Past ARC Conventions at IRES


(ARC Convention 09/14-018)

Five year interdisciplinary project on issues of sustainability starting October 1, 2009. Topics to be investigated include specific issues relevant to intergenerational justice, sustainability criteria and Pontryagin optimality, optimal population size, population composition and dynamics, population policy, the problem of short-termism, the choice by firms of sustainable technology.

Objectives – The concept of sustainability is everywhere. Yet, the analytical questions it raises are far from settled. This is true of course in the natural sciences. It is equally so in other disciplines such as economics or philosophy. Consider the question ‘Are we consuming too much?’ raised by a group of economists led by Nobel Prize winner K. Arrow. While consumption per head is rising in the West, how should we factor in the depletion of our natural resources as well as the growth of the world population? Extensive conceptual work is required – including on technological and demographic aspects - if we are to move beyond principles such as Brundtland’s view that sustainable development is characterized by the fact that ‘…[it] meets the needs of the present without compromising the ability of future generations to meet their own needs’.

Geographical mobility of factors 

(ARC Convention 09/14-019) 

Five year interdisciplinary project on issues of geographical mobility of factors starting September 1, 2009. Topics to be investigated include determinants of factor mobility, interdependencies with public policies and economic performances, analysis of mobility at various geographic scales.

Objectives – Recent increases in trade and capital flows, foreign direct investments and labor mobility have intensified the integration of national and regional economies, and strengthened the competition between them for both better and worse. At the international or intra-national levels, economies with high skill endowments keep on attracting scarce factors, generating generous return rates and increasing their supremacy. The polarization of economic activities and the concentration of scarce factors (such as knowledge and skills) are shaping both the world and the internal evolution of countries. Through five connected axes, the purpose of this project is to enhance the understanding of the determinants of factor mobility and the interdependencies between factor mobility, public policies and economic performance. Axes 1 and 2 belong to the literature on the determinants of international factor mobility. The novelty of our approach is that it is based on new and unique databases on workers’ and firms’ mobility. In axes 3 to 5, we build bridges between different strands of literature to characterize the joint determination of factor mobility, economic performances and institutions (including public policies, norms, social capital, etc.).

Promoters: Frédéric Docquier (coordinator), Henri Sneessens, Jacques Thisse, Hylke Vandenbussche, Bruno Van der Linden.

II. Description of the five axes

Axis 1: Dynamics of migrants’ diasporas

Axis 1 focused on the determinants of international labor mobility. The dynamics of migrants’ diasporas (defined as the stock of people born in a country i and living in another country j) is the outcome of a complex combination of self-selection (i.e. endogenous decisions of heterogeneous individuals to leave their country) and out-selection mechanisms (i.e. host-country decisions to accept immigrants, reflected in their immigration policies). How do characteristics of existing diasporas (size, education level, gender structure) affect the size and structure of current migration flows? How do existing diasporas impact on the effectiveness of immigration policy reforms? In particular, would more selective immigration policies generate important effects on the structure of EU immigration flows? In this axis, we improved existing databases on the size and structure of bilateral migration flows. For the first time, we developed comprehensive database on migration stocks by education and gender covering about 40,000 corridors (200 countries of origin and destination). We coupled our databases with new data on the desired migration (i.e. people who would like to emigrated but have not yet done it). We used these data sets to analyze the determinants of migration, to quantify and disentangle diaspora externalities. As for the methods, we collected and harmonized a large number of isolated data, and used empirical techniques to identify the determinants of migration.

Our scientific activities under Axis 1 involved two early-stage researchers funded by ARC (A. Kayaoglu, S. Salomone), one non-funded early-stage researcher (A. Ariu), one post-doc researchers funded by ARC (I. Ruyssen), and ten external collaborators (E. Artuc, M. Beine, L. Lowell, A. Marfouk, C. Ozden, C. Parsons, G. Peri, H. Rapoport, K. Sekkat, M.P. Squicciarini). Our main findings under Axis 1 can be classified in three categories:

  • A first set of papers, written during the first two years, presents new database documenting the size and structure of international migration flows. In 2009, we built on our previous databases on migration stocks to OECD countries, updated the data using new sources, standardized 1990 and 2000 categories, and introduced the gender breakdown. For the first time, we developed new data on stocks and rates of emigration by level of schooling and by gender. The same year, we complemented the literature through three case studies on very different regional and professional contexts: the African medical brain drain, the exodus of European researchers to the United States, and the contribution of the Indian diaspora to the rise of the IT sector in India. More importantly, we developed a new dataset of international bilateral migration stocks by gender and education level, which includes both OECD and non-OECD countries as destinations in 1990 and 2000. Census data were available for a large number of developing countries. For the sake of comprehensiveness, we used pseudo-gravity model regressions to impute missing values where data are unavailable, such that we are able to provide, for the first time, a global assessment of human capital mobility. The comprehensiveness of the resulting matrices facilitates a more nuanced definition of emigration rates based on the concept of the natural labor force, which additionally considers both entries and exits of workers. Although the paper is still forthcoming in an academic journal, this project was initiated as early as in 2009 and was used in several studies under Axes 1, 3 and 5.
  • Second, we produced several papers looking at the determinants of migration flows and quantifying the size of diaspora externalities (i.e. effect of existing network on new flows). We found that diasporas increase migration flows and lower their average educational level. Interestingly, diasporas explain majority of the variability of migration flows and selection. This suggests that, without changing the generosity of family reunion programs, education-based selection rules are likely to have moderate impact. Availability of new data by gender enabled us to identify the factors influencing the gender composition of migration. We found that network effects vary by education level but not by gender. In two recent works in progress, we investigated the role of governance quality on bilateral migration flows, and disentangled diaspora externalities into its two components: the effect on private assimilation costs (self-selection channel) and the effect on legal entry barriers through family reunification programs (immigration policy channel). Another paper by Kayaoglu quantified the effect of the state of emergency (i.e. military presence of Turkish soldiers in Eastern and South-Eastern regions of Turkey) on economic performance and migration out of the region.
  • Third and more recently, we obtained access to a large-scale database on willingness to emigrate (the Gallup world poll survey). We analyzed empirically what country-specific and bilateral factors determine the size (and composition between education groups) of the pool of potential migrants. The latter is defined as those who have revealed being willing to migrate by positively answering the question “Ideally, if you had the opportunity, would you like to move permanently or temporarily to another country, or would you prefer to continue living in this country?”. Most of them have, then, indicated a preferred country in the follow-up question “To which country would you like to move?”. In the second step, we analyzed how these potential migrants combine with factors determining migration opportunities and generate actual migration flows. We found that the size of the network of previous migrants and the average income per person at destination are crucial determinants of the size of the pool of potential migrants. Economic growth in the destination country, on the other hand, is the main economic generator of migration opportunities for a given pool of potential migrants. We also found that college educated exhibit greater actual emigration rates mainly because of better chances in realizing their immigration potentials, rather than because of higher willingness to migrate. The new data on desired migration were abundantly used in Axis 3.

Axis 2: Mobility and dynamics of firms

Axis 2 focused on globalization and the determinants of firms’ internationalization and mobility. The amount of exports and worldwide Foreign Direct Investment (FDI) has risen spectacularly in the last decades. This has triggered substantial efforts to integrate the increase in firm’ internationalization into the neo-classical theory of international trade. In this axis, we aimed to make both theoretical and empirical contributions in this direction. Theoretically, we aimed to modify existing trade models to rationalize findings in the data that cannot be explained by existing trade models. We identified new determinants of trade in the theory and find convincing empirical evidence for them. The latest trade theories explains firm-level trade mainly through firm-level productivity. These models argue that only firms with high enough productivity can engage in exporting and in FDI. But this supply-side explanation of trade, while important, is unlikely to capture all the features of the data. In this axis, we developed models that explore the importance of demand-side trade determinants. We allowed firms to differ in the quality they export and allow consumers within a country and across countries to be heterogeneous in their taste for products. Quality and taste differences across products are a powerful source of exports, but thus far could not be disentangled clearly in the theory. We presented new models that clearly separate quality from taste effects with clear predictions on how export prices and quantities are affected by both. We collaborated with the National Bank of Belgium and used firm-level data to test our new theory and find that quality and taste are important determinants of firm-level exporting. We also used this data to explore the phenomenon of “carry-along trade” where we showed that firms often export products that they do not produce. The existence of substantial “carry-along trade” in the data goes against the maintained assumption in the theory that firms only export what they produce. Lastly, we also explored the multi-product nature of firms. We showed that the large majority of Belgian exporters are multi-product firms. Again this evidence is in strong contrast with the mainstream assumption in trade models that firms are single-product firms. The empirical evidence that we provided, seriously questions this assumption which opens a whole range of new issues that will need to be tackled in the presence of multi-product exporting firms.

The scientific activities under Axis 2 involved the work by six researchers supported by financial means of ARC. Most of them obtained their PhD (F. Di Comité, E. Forlani, A. Khatibi, L. Rovegno, A. Sissokko, C. Viegelahn) and another student is still under way (S. Blanas). Our activities involved one postdoc non-funded researcher (J. Martin) and thirteen external collaborators (C. Altomonte, A. Bernard, E. Blanchard, J. Hartigan, K. Miyagiwa, S. Poncet, H. Song, T. Sono, W. Steingress, J. Konings, I. Van Beveren, J. Wauters, M. Zanardi). Several published papers have been turned into non-technical summaries and published on the global internet forum VOX. Our main findings can be summarized as follows:

  • In a first set of papers we showed that existing trade models are not well suited to explain all the variation in firm-level exporters data. Thus we showed that the firm-level cost side and productivity can at best only offer a partial explanation of exporter performance success. We argue that the missing source of variation must come from the demand side. We developed a new theoretical framework that incorporates important features of demand side aspects, i.e. quality and taste differences between firms and products.
  • In a second set of papers, we showed another weakness of existing trade models. In those models, it is assumed that firms only export one product i.e. firms are single-product firms. However, our own empirical findings showed that for Belgian data this assumption is violated. Most Belgian exporters are multi-product firms. The multi-product nature of firms brings about a whole range of new issues that now have to be taken into account in trade models (cannibalization issues, demand complementarity in exports etc). Thus we showed that existing models of firms’ exports need to be about multi-product firms. We developed a new model of multi-product firms that can account for cannibalization and demand complementarities and showed that this model is able to explain some additional features of the data that existing models cannot capture.
  • In a third set of papers, we questioned a third important assumption of existing trade models, i.e. that firms only export products that they actually produce. However, in the data we found evidence that many firms export products that they do not make themselves. We coined this observation as “carry-along trade”. We developed a model that can explain carry-along products, i.e. product that firms purchase from other domestic suppliers to export jointly with their main products that they produce in house. The underlying determinants of carry-along trade can be found both on the supply-side where rising costs imply that some products are better outsourced, but we also showed that complementarity in demand on the consumers’ side incentivize firms to export both types of products.
  • In a final set of papers, we explored various features of firm internationalization. We measured quality in exports and we looked into the importance of access to finance for exporting firms.

Axis 3: Brain drain, growth and economic policies

Axis 3 focused on the links between migration and economic performance. Although the recent literature suggests that migration generates positive spillover effects on countries of origin, many economists see it as a curse for the developing world because it is skill-biased (or of a brain-drain nature). Nevertheless, even in this pessimistic context, it is crucial to clarify how causatin operates. Does high-skilled emigration cause poverty or does poverty induce emigration? Many studies suggest that both links are operating simultaneously. However, in the recent brain drain literature, the analysis of these two causal links has given rise to two separate strands. In this axis, we refined the analysis of the consequences of migration for sending and receiving countries, and built bridges between the various strands using unified models and examining the complex interactions between emigration decisions and economic performance in origin and destination countries. As far as the methodologically is concerned, we combined empirical methods and quantitative theory. The latter consists of stylized models calibrated to match current or historical observations, and then simulated under alternative policy scenarios.

Our scientific activities under Axis 3 involved four early-stage researchers funded by ARC (A. Kayaoglu, J-F. Maystadt, S. Salomone, C. Vasilakis), four non-funded early-stage researchers (A. Aubry, M. Burzynski, M. Delogu, J. Machado), two post-doc researchers funded by ARC (A. Jakobbson, I. Ruyssen), two non-funded postdoc researchers (M. Mercier, S. Salomone), and seventeen external collaborators (M. Beine, A. Bhargava, C. Defoort, D. de la Croix, A. Kaya, M. Le Goff, E. Lodigiani, L. Marchiori, Y. Moullan, C. Ozden, G. Peri, L. Ragot, H. Rapoport, K. Sekkat, M. Schiff, I. Shen, P. Verwimp). Our main findings can be classified in four categories:

  • In a first set of papers, written in 2010 and 2011, we empirically confirmed the existence of significant links between skill-biased migration prospects and human capital formation. Compared to the existing literature, we used alternative specifications, databases (including panel data) and estimation techniques. We took advantage of the new databases on the size and structure of migration developed under Axis 1.
  • A second set of papers sheds light on the implications of emigration (of low-skilled workers, high-skilled workers, physicians, refugees) for sending countries. Our quantitative models account for effects on wages and employment, fertility and education, productivity, health, remittances, probability of a military conflict. We also examined the behavioral effect of emigration through transfers of norms (fertility or political norms) and quantified diaspora externalities (effect of migration network on trade and investment costs).
  • A third set of papers investigates the implications of immigration for receiving countries. We focused on the labor market, fiscal, productivity and market size effects of immigration. The use of quantitative models enabled us to quantify the welfare impact of immigration and to identify the relative contribution of each channel of transmission. In addition, some of our interdisciplinary contributions examined the effect of refugees’ migration and the social integration of immigrants.
  • And finally, the interactions between migration and economic performance was studied in new integrated models, highlighting the possibility of multiple equilibria in emigration and poverty outcomes. We showed that this is an issue for small island developing countries which, for this reason, require appropriate policies. In the recent months, we obtained the permission to use a unique database on the willingness to emigrate. This database covers almost all the countries of the world. We used it to disentangle migration costs into its private and legal components. On this basis, we revisited the literature on the efficiency and inequality effects of a further liberalization of migration flows. Contrary to previous studies, we predict much small migration responses and economic effects. Interestingly, we established strong similarities between the effect of a skill-biased liberalization of labor mobility and what occurred in football after the 1995 Bosman ruling.

Axis 4: Workers’ mobility and labor market institutions

In Axis 4, we studied how job and worker flows and their geographical distribution determine the within-country distribution of (un-)employment and income. More precisely, our objective was to examine the mechanisms by which geographical disparities in employment and income may arise and persist over time. A priori, one could think that labor mobility contributes to eliminate or at least reduce spatial disparities. We showed that some imperfections in the residential mobility interact with search-matching frictions to yield non negligible levels of equilibrium unemployment rates despite perfect mobility of jobs. The wage and unemployment performance of African-Americans and African migrants is a major concern. The role of “contact jobs” as a source of discrimination and the role of public housing had not been much studied in the literature. Interacted with residential mobility, they both turn out to deeply affect the position of these discriminated workers. Axis 4 relied on the search and matching framework where imperfect information generates frictions and a positive equilibrium unemployment rate. This framework was extended by making the spatial dispersion of workers and jobs explicit. So doing, one could see how decision locations (about residence and where to search for a job) interact with the housing and the frictional labor market. Getting as many analytical results as possible was the aim. However, the complexity of the interactions makes numerical analyses needed. Our models were calibrated for regions and MSAs in the US and then simulated. An alternative approach was also developed, namely the collection of large individual data sets and the application of micro-econometric techniques to estimate reduced-form models.
In the equilibrium job-search theory, it has been shown by Burdett and Mortensen that identical workers can be paid differently if there is on-the-job search and wage posting. We reached a similar dispersion among identical workers when geography matters. With the models developed within Axis 4, the equilibrium values of unemployment and earnings can be dispersed even when job centers are identical and workers are equally productive. To get this conclusion, we introduced explicitly the spatial distribution of jobs and workers in theoretical settings where the mobility of workers (between locations and between unemployment and employment) is imperfect and/or, thanks to nowadays communication technologies, job-seekers can search in different regions without first migrating. In all cases, inefficiency of the allocation in the laisser-faire economy is the rule rather than the exception. Discrimination had been studied for a long time. The originality of the research conducted in Axis 4 is threefold. First, the specific role of consumer discrimination through ‘’contact jobs’’ was investigated and shown to be important. Second, the interaction between discrimination and residential mobility was accounted for. The conclusion is that taking into account the sorting process due to residential mobility does not change the conclusion that relative earnings of African-Americans are lower in areas where the proportions of prejudiced individuals and of contact jobs are high. Third, the geographical distribution of public housing (a major institution in some European countries) distorts the efficient allocation of labor and hence affects the labor market outcomes of African immigrants in France.

Axis 4 was mainly supervised by Bruno Van der Linden and Henri Sneessens. One full-time researcher, Paola Montero Ledezma, has been affected to this axis. A second researcher not financed by the ARC contract, Vanessa Lutgen, has been associated to the project. Finally, a post-doc researcher, Morgane Laouenan, has also been affected to this axis. In collaboration with the promoters and external collaborators, the two first researchers have developed new search/matching models of the equilibrium unemployment rate when individuals and firms are spatially distributed. The post-doc researcher has studied the interaction between ‘’contact jobs’’, the housing market and discrimination against African-Americans and African migrants in France. Our activities involved eight external collaborators (A. Bucher, P. Combes, B. Decreuse, E. Lehmann, A. Trannoy, G. Verdugo, W. Xiao, Y. Zenou). Our main findings can be described as following:

  • The research of Paola Montero Ledezma generated four papers, one of which is under revision at the Journal of Urban Economics. The defense of her PhD is expected in March 2015. These papers are at the boundary between Urban economics and Labor economics. They intend to understand how equilibrium unemployment can be the consequence of the spatial distribution of workers and jobs in the presence of search-matching frictions. They also study the efficiency of the allocation of resources. The research of Vanessa Lutgen has currently two outputs at the boundary of Regional economics and Labor economics. The aims are the same as in the case of the first researcher. However, commuting is ruled out and replaced by endogenous inter-regional migration. The first output is a static model under revision at Regional Science and Urban Economics. The second paper is an extension of the first one in a dynamic setting. All these papers conclude that besides a number of factors that are standard in labor economics, geography matters when one intends to understand the causes of equilibrium unemployment. Workers’ and firms’ mobility is not sufficient to eliminate unemployment in these theoretical settings. The allocation of resources is inefficient in a laissez-faire decentralized economy. In each case, the models were calibrated and simulated to provide orders of magnitude of the effects.
  • In a paper forthcoming in the Journal of Labor Economics, Morgane Laouenan investigates the link between the over-exposure of African immigrants to unemployment in France and their under-representation in jobs in contact with customers. The results show that there is both employer and customer discrimination in the French labor market. The other papers are either submitted (one under revision at Labour Economics) or work-in-progress. Two papers exploiting US data proved that racial discrimination are detrimental to employment and wages of African-Americans and that this effect is not driven by their residential mobility out of prejudiced areas. In a last paper, she showed that ethnic networks in public housing influence both the residential location choice of African immigrants and their labor market outcomes. All these papers of Morgane Laouenan used the search and matching framework and develop a thorough micro-econometric analysis.

Axis 5: Mobility at various scales

Axis 5 focused on the links between international, interregional and intra-regional movements of factors. Urban economics and new economic geography have uncovered the underpinnings of urban agglomeration and regional disparities, thus explaining spatial inequality at various spatial scales. The aim of the current axis was to build bridges between the international and the regional levels by developing new theoretical frameworks as well as empirical testing of some of the predictions arising. In this axis, we examined the interactions between, intra-national labor mobility, between the rural and urban sectors or between the informal and formal sectors, and economic development. Our team is now introducing high-skilled international migration in this framework; he investigates the link between international migration and rural-to-urban migration within the country. Second, we studied the determinants of international migrant’s location choice in Belgium. Methodologically speaking, the first set of papers used quantitative theory and parametrized models on developing or sub-Saharan African countries. The paper on location decisions of foreigners used structural econometrics.

Our scientific activities under Axis 5 involved one early-stage researchers funded by ARC (A. Kayaoglu), one non-funded early-stage researchers (M. Delogu), one post-doc researchers funded by ARC (I. Ruyssen), and five external collaborators (H. Jayet, T. Müller, J. Naval Navarro, G. Rayp, N. Ukraynchuk). We obtained the following three main findings:

  • First, we studied the dynamic implications of informality for developing countries. Indeed, one of the most salient features of poor economies is the existence of a large, sometimes predominant, informal sector. Although informality serves to protect low-skilled workers against unemployment, it has important implications for the long-run development of developing countries. On the one hand, informality increases the income level of poor households and the potential demand for education. On the other hand, it negatively affect the returns to education and increase the opportunity cost of children (by facilitating child labor). We investigated the dynamics effects on income inequality, human capital accumulation and development. Our model can generate transitory informality equilibria or informality-induced poverty traps. Its calibration reveals that the case for the poverty-trap hypothesis is strong: although informality serves to protect low-skilled workers from extreme poverty in the short-run, it prevents income convergence between developed and developing nations in the long run. We examined the effectiveness of different development policies to exit the poverty trap
  • The second paper investigated the complex interactions between education, urbanization and development. Since Lucas (1988) and Azariadis and Drazen (1990), human capital disparities have been given a central role in the analysis of growth and development. In addition, it has long been argued that there is a close connection between urbanization and economic growth. Hence, it is a paradox that, in the second half the past century, the highest progress in schooling and urbanization was observed in sub-Saharan Africa, the region with the lowest GDP per capita growth rates. We built a unified model endogenizing human capital accumulation, urbanization and economic development in a model with temporary urbanization costs. The model was calibrated on Africa using panel regressions and identification hypotheses. It does an excellent job in fitting historical data on the proportion of college graduates, share of urban population and growth in GDP per capita. The model was then used to predict the evolution of the key variables for the next decades. Due to those temporary urbanization costs, rapid urbanization and human capital development in Africa have not yet given rise to high economic growth rates. However they create a latent growth potential (referred to as the African growth backlog) which will gradually materialize when urban population and human capital will have reach stable levels. In the same framework, Marco Delogu has introduced high-skilled international migration to investigate the link between international migration and rural-to-urban migration within the country. As brain drain operates, the demand for low-skilled labor decreases in cities. This slows down the urbanization process and the accumulation of human capital. Marco uses numerical simulations to investigate the short-run and long-run impacts on the economy.
  • Finally, Ilse Ruyssen’s paper studied migratory streams to Belgian municipalities between 1994 and 2007. The Belgian population register constitutes a rich and unique database of yearly migrant in flows and stocks broken down by nationality, which allows us to empirically explain the location choice of immigrants at municipality level. The analysis enables to disentangle the network effect, captured by the number of previous arrivals, from other location-specific characteristics such as local labor or housing market conditions and the presence of public amenities. It was shown that the spatial repartition of immigrants in Belgium is determined by both network effects and local characteristics. The determinants of local attractiveness vary by nationality but, for all nationalities, they dominate the impact of network effects.

Training of non-funded PhD students

Six non-funded PhD students benefitted from the ARC environment and defended their PhD:

  • Emanuele Forlani
  • Arastou Khatibi
  • Laura Rovegno
  • Aminata Sissoko
  • Andrea Ariu
  • Christian Viegelahn
  • Joël Machado

Training of non-funded PhD students who have not yet defended

Five other non-funded PhD students have not yet defended:

  • Amandine Aubry
  • Sotiris Blanas
  • Michal Burzynski
  • Marco Delogu
  • Vanessa Lutgen

Training of postdocs funded by ARC

Three postdoc students were funded by ARC:

  • Morgane Laouenan joined IRES for a one-year postdoc position in October 2012. Morgane conducted research on discrimination against ethnic minorities in the labor market. In her PhD thesis, she used individual-level data to study the impact of racial prejudice on labor market outcomes of minorities, such as employment, wages and probability of occupying a job in contact with consumers. Her research focused both on African immigrants in France and on Afro-Americans in the US. Morgane stayed at IRES between October 2012 and August 2014 and took part of the ARC project on “Geographical mobility of workers and firms”. She worked on the links between labor market institutions, unemployment and labor mobility between regions.
  • In September 2013, Ilse Ruyssen joined IRES for a one-year postdoc. Ilse obtained her PhD from Ghent University. In her dissertation, she empirically investigated the determinants of international migration and migrants’ location choice. The focus was on identifying the driving forces of migration to the OECD and between African countries, with specific attention to dynamic processes and spatial dependence. She also analyzed to what extent immigrants’ choice of residence within Belgium is driven by networks versus the genuine appeal of municipalities. Another part of her research involves the role of European immigration policies in shaping migration streams from African countries. At IRES, she exploited new micro-data on desired migration. She compared desired migration with actual migratory movements and studies how removing legal migration barriers could affect migration flows. She was also involved in another research project on bilateral migration and international conflicts.
  • In January 2014, Amanda Jakobsson joined IRES for a six-month postdoc under the ARC convention on “Geographical Mobility of Workers and Firms”. She was on leave from Singapore Management University where she is Assistant Professor of Economics after obtaining her PhD from Stockholm School of Economics in June 2013. In her dissertation, she developed and calibrated dynamic general equilibrium models of North-South trade to study the role of intellectual property rights for exporting and foreign direct investment (FDI). The focus was on disentangling the impact of trade liberalization and stronger patent protection in developing countries on innovation, technology transfers and consumer welfare. At IRES, she studied how the location of multinational firm activity affects international migration of skilled labor in developing countries. More precisely, she investigated whether investments by multinational firm in nearby countries increases the emigration of high-skilled workers, spurring the brain drain and the geographic concentration of talents within developing countries.

Training of non-funded postdocs

Three other non-funded postdocs were closely related to our team:

  • Julien Martin
  • Sara Salomone
  • Marion Mercier

V. Events


Mid-term workshop on “Geographical Mobility of Workers and Firms”

A multi-axis workshop was organized at IRES on January 17-18, 2012. This workshop was financially supported by the Belgian French-speaking Community (convention ARC 09/14-019) and the FRS-FNRS (Fonds de la Recherche Scientifique). The organizers were Frédéric Docquier, Khalid Sekkat, Hylke Vandenbussche and Bruno Van der Linden.

International conference on “International labor mobility and inequality across nations"

picture conference ferdiIn the framework of the ARC research project on “Geographical Mobility of Workers and Firms”, IRES organized an international Conference on "International labor mobility and inequality across nations". The event was jointly organized with FERDI/CERDI (Université d’Auvergne) and was held in Clermont-Ferrand on January 23-24, 2013. The conference was devoted to investigating the effects of international migration on the geographic distribution of human capital and its implications for the world economy (Axis 3). Questions addressed were: How large are migration flows (by education and by gender)? How does labor mobility affect inequality across nations? What are the determinants of migration flows/stocks? Are policy barriers quantitatively important? How would the world economy respond to a (selective or non-selective) liberalization of labor mobility? The conference included presentations by invited renowned speakers (Michel Beine from the University of Luxembourg, Jesús Fernández-Huertas Moraga from FEDEA-IAE-CSIC, Mäelan Legoff from CEPII, Andrew Mountford from Royal Holloway London, Çaglar Özden from the World Bank, Chris Parsons from the University of Oxford, Hillel Rapoport from Bar Ilan University, Sara Salomone from IRES), one dinner speech by Paul Collier from the University of Oxford, and 24 selected papers organized in 8 thematic sessions. A selection of papers from the conference is now being considered for a special issue of The World Economy.

Scientific committee: Simone Bertoli (CERDI UdA), Jim de Melo (Unige and FERDI), Frédéric Docquier (IRES and FERDI) and Patrick Guillaumont (FERDI). Local organizers: Simone Bertoli (CERDI UdA), Vianney Dequiedt (CERDI UdA), Frédéric Docquier (IRES and FERDI) and Kelly Labart (FERDI).

International Conference on "Labor Mobility, the Housing Market and Labor Market Outcomes”

In the framework of the ARC research project on “Geographical Mobility of Workers and Firms”, Axis 4 organized in Louvain-la-Neuve an international Conference on "Labor Mobility, the Housing Market and Labor Market Outcomes”. This workshop was held on May 22-23, 2014. Regional disparities in unemployment and wages are large, often persistent, and presumably not efficient. The workshop aimed at bringing together high-quality papers that address the following questions. To what extent are these disparities due to a range of frictions (search-matching frictions, lack of labor mobility, etc.), imperfect competition or discrimination? Is the functioning of the housing market (homeownership, housing busts, etc.) part of the explanation? Do agglomeration forces reinforce/reduce these disparities? Is public intervention an additional cause or instead required to correct inefficiencies? During the workshop, three keynote lectures were given by respectively Paul Beaudry (UBC), Etienne Wasmer (Science Po, Paris) and Yves Zenou (Stockholm University). Fifteen other presentations from all over Europe, the US, and Canada were of high quality.

Organizers: Mathias Hungerbühler (Université de Namur), Morgane Laouénan, Vanessa Lutgen and Bruno Van der Linden (Université catholique de Louvain).

Visiting research program

 Thanks to ARC funding, IRES has initiated a new Visiting Research Program. We invite leading international experts for a research stay at IRES. Experts give a research seminar, and meet our members and colleagues from UCLouvain to exchange ideas. 

  • IRES hosted Tobias Müller between October 1 and 31, 2011. Tobias is an associate Professor of applied economics at the University of Geneva. After completing his PhD at the University of Geneva, he was invited Professor at the University Laval in Québec. He has also served as a consultant for the World Bank and the Swiss federal government. His research focuses on different aspects of migration (temporary migration, political economy of migration, trade and migration networks) and on the analysis of tax-benefit reforms and their impact on income distribution and the labor market. His past research also includes studies on European integration using computable general equilibrium models. Tobias gave a presentation on «The political economy of naturalization: the Swiss case» at the IRES Research seminar and interacted with our migration team. We started new projects on trade and migration, attitudes towards immigrants, and the effects of informality on development.
  • We hosted Oded Galor from Jan 24 to Feb 6, 2012. Oded is the Herbert H. Goldberger Professor of Economy at Brown University. He obtained his PhD in Economics from the University of Columbia (1984). Since then, he has produced many seminal contributions to the study of income distribution and economic growth, the transition from stagnation to growth, human evolution and economic development, the study of development traps, the demographic transition, and the advancement of the foundations of overlapping-generations models. He has founded the field of Unified Growth Theory, a theory of growth incorporating an evolutionary perspective and being able to account for the transition from Malthusian stagnation to the modern growth regime. He serves on the editorial boards of several journals, including the Journal of Economic Growth (Editor), Journal of Population Economics (Associate Editor) and Macroeconomic Dynamics (Associate Editor). Since 1995, he has been co-director of the National Bureau of Economic Research group on Income Distribution and Macroeconomics. During his stay, he interacted with many PhD students as well as faculty members of IRES. Oded also gave two presentations. On Jan 27, he gave a keynote lecture on "Cultural Diversity, Geographical Isolation, and the Origin of the Wealth of Nations", in which he argues that variations in the interplay between cultural assimilation and cultural diffusion can account for differential patterns of economic development across the globe. On Feb 2, he presented his paper on "The Out of Africa Hypothesis, Human Genetic Diversity, and Comparative Economic Development" at the IRES Research Seminar. This paper states that variations in migratory distance from the cradle of humankind to various settlements across the globe affected genetic diversity and deeply influenced the pattern of comparative economic development.
  • We also invited Etienne Lehmann in April 2012. Etienne is Professeur des Universités affiliated to CREST (INSEE) and on leave from Paris II. He is member of CESifo (Munich) and IZA (Bonn). He is also an IRES research associate. In 2011, he has been nominated for the 2011 prize for the best young economist. This annual prize is awarded by the Newspaper Le Monde and the Cercle des économistes to researchers in Economics on the basis of academic excellence and policy outreach criteria. In 2012, he has been nominated to become junior member of the Institut Universitaire de France. Etienne Lehmann's research interests are mainly in Public Economics and Macroeconomics. He is in particular a renowned expert in the field of Optimal Taxation. He has published in the Review of Economic Studies, the Journal of Public Economics and the Scandinavian Journal of Economics among others. He has collaborated for more than ten years with Bruno Van der Linden.
  • Maurice Schiff visited IRES between September 16 and 20, and between October 24 and 29, 2013. Maurice got his PhD from the University of Chicago. He spent two years as Professor and Research Director of the Faculty of Economics and Business of the University of Concepcion in Chile. He then served as a Lead Economist in the World Bank International Trade Unit (Development Research Group) and directed the Research Program on International Migration until 2012. He is presently International Consultant in the Development Economics Research Group at the World Bank. His fields of expertise are international trade, agriculture, regional integration, trade and technology diffusion, and international migration. He published more than ten books and many articles in journals such as Journal of International Economics, European Economic Review, Journal of Development Economics, World Bank Economic Review, American Journal of Agricultural Economics, Canadian Journal of Economics, etc. During his stay at IRES, Maurice collaborated with Frédéric Docquier, Fabio Mariani and Ilse Ruyssen on several issues such as (i) the relationship between bilateral migration, trade and international conflicts, (ii) the labor market integration of immigrants in the OECD countries, and (iii) political economy models of immigration policies. Maurice’s stay at IRES was funded by the ARC convention on “Geographical mobility of workers and firms”.
  • Giovanni Peri visited IRES between March 4 and 8, 2013. This event was initiated by IRES and organized under our Visiting Research Program. Giovanni Peri is Professor of Economics at University of California at Davis, Research Associate of the National Bureau of Economic Research, Research Professor at Ifo in Munich, and affiliated with IZA-Bonn and CReAM-London. Giovanni obtained his PhD in Economics at Berkeley in 1998. Since then, he has published many influential papers on the impact of international migrations on labor markets, housing markets and productivity of the receiving countries and on the determinants of international migrations. His works have been published in academic journals such as the American Economic Review, the Review of Economic Studies, the Review of Economics and Statistics, the European Economic Review and the Journal of European Economic Association. Giovanni is Editor of Regional Science and Urban Economics and acts as a member of the editorial Board of five other academic journals in economics. Giovanni has a joint research project at IRES with Frédéric Docquier on the determinants of intentions to emigrate and on the identification of legal immigration barriers. This project is part of our ARC-funded research program on “Geographical mobility of workers and firms”. During his stay, Giovanni had many fruitful interactions with PhD students and faculty members of IRES. On March 7, he gave a presentation on the growth impact of STEM workers (Scientists, Technology professionals, Engineers and Mathematicians) in the United States. His analysis reveals that STEM workers contributed importantly to total factor productivity growth and changes in returns to schooling between 1990 and 2010. And a large fraction of the change in STEM employment has been supply-driven by the expansion of the H1-B immigration visa program.
