Prequalifications and information acquisition in procurement auctions

Abstract: I model the impact of firms’ endogenous research in a renewable energy capacity procurement auction. I include a technological cost in the auction which acts as a common-value component. I find that, at equilibrium, endogenous research creates a business-stealing effect in the auction, leading too many firms to conduct research. This in turn implies that prequalification requirements for the auction based on information about project costs are inefficient and reduce social welfare. Second, when auctions exist for two substitute technologies, such as PV and wind, it is not necessarily optimal to link the auctions across technologies. Finally, using a database of European Union auctions, I find some empirical evidence of endogenous research.

Private Preferences for Jobs and Labor Market Dynamics 

Abstract:

We build a new dynamic search model in which workers have heterogeneous preferences for jobs that are not observed by employers, giving rise to monopsony. Employers make wage offers based on beliefs about workers' preferences. These beliefs evolve endogenously over time because workers' mobility decisions reveal information about how much they like their jobs. We estimate the model using matched employer-employee data from France and quantify how preferences for jobs shape wage dynamics, markdowns, and worker mobility.

Please register via this form :Identity and Policy Design workshop 

Economic decisions are often shaped by social identity, through norms, group membership, or self-image. The study of its implications for behavior is expanding to an increasingly broad set of groups and norms (e.g., gender, race, class, age, caste), and its normative implications are receiving growing attention. In this workshop, we aim to bring together researchers working on theory and empirics, on positive and normative questions alike, to inform better policy design.

An algorithmic procedure for solving the generalized minimum information checkerboard copula problem

Abstract: 
The minimum information copula principle (see Meeuwissen and Bedford, 1997) is a maximum entropy-like approach for finding the least informative copula that satisfies a certain number of expectation constraints specified either from expert knowledge or the available limited data. In this presentation, we first propose a generalization of this principle allowing the inclusion of additional constraints fixing certain higher-order margins of the copula. We next prove that the associated optimization problem has a unique solution under a natural condition. As the latter problem is intractable in general, following the existing literature, we consider its version with all the probability measures involved in its formulation replaced by checkerboard approximations. This amounts to attempting to solve a
so-called discrete I-projection linear problem. We then use the seminal results of Csiszar (1975) to derive an IPFP-like procedure for solving the latter and provide theoretical guarantees for its convergence. We next report numerical experiments in dimensions up to four with substantially finer discretizations than those encountered in the literature. We finally discuss the computational cost of the procedure and hint at memory saving implementations that should allow to tackle higher dimensional problems under certain conditions.
