Purpose – This editorial aims to introduce the special issue on employment discrimination against immigrants. Design/methodology/approach – The first part is a commentary on key issues in the study of employment discrimination against immigrants. The second part presents the five articles in...

We study the optimal auction problem with participation costs in the symmetric independent private values setting, where bidders know their valuations when they make independent participation decisions. After characterizing the optimal auction in terms of participation cutoffs, we provide an...

I study a multi-player mechanism design problem where the players are able to collude. I characterize the extent that the principal can link the compensation level of one of these players to the production performance of the other. I use this characterization result to identify the optimal...

The paper explains new methodology that was used in the 2005 International Comparison Program (ICP) that compared the relative price levels and GDP levels across 146 countries. In this round of the ICP, the world was divided into 6 regions: OECD, CIS, Africa, South America, Asia Pacific and West...

We study how competing matchmakers use prices to sort participants into search markets, where they form random pairwise matches, and how equilibrium outcomes compare with monopoly in terms of prices, search market structure and sorting efficiency. The role of prices to facilitate sorting is...

We model, using evolutionary game theory, the implications of endogenous determination of preferences over the outcomes of any given two-player normal form game, G. We consider a large population randomly and repeatedly matched to play G. Each individual has a preference relation over the...

Technical supplement to the paper forthcoming in Rand Journal of Economics.

We study an adverse selection problem, where an agent is able to understate his productivity, but not allowed to overstate it. The solution to this problem is generally different than the solution to the standard problem, where no restriction is made on the statements of the agent. We identify a...
