Economists have argued that a high concentration of land holdings in a country can create powerful interest groups that retard the creation of economic institutions, and thus hold back economic development. Could these arguments apply beyond underdeveloped countries with backward political...

This paper uses new data to reexamine trends in concentration in U.S. markets from 1994 to 2019. The paper's main contribution is to construct concentration measures that reflect narrowly defined consumption-based product markets, as would be defined in an antitrust setting, while accounting for...

This survey examines recent developments in economic research relating to antitrust, paying specific attention to research in the areas of collusion and merger enforcement. Research relating to both collusion and mergers has made significant advances in the last twenty years. With respect to...

In essence, this paper will try to decompose the concentration-profits relationship into separate concentration-price arid concentration-cost relationships. By doing this, I hope to shed light on some of the allocative and distributive issues that, I suspect, give the subject its intrinsic...

We study the relationship between market structure and public procurement outcomes. In particular, we ask whether and to what extent consolidation-driven increases in industry concentration affect the way in which the government procures its goods and services. We focus on the defense industry,...

We analyze the role of three aspects of HMO market structure -- HMO penetration, HMO plan concentration, and HMO for-profit share on explaining hospital cost and revenue growth during the HMO expansion period (1994-1999) and backlash period (2000-2005). We find that HMO penetration effects...

Using patents as indicators of inventive activity, this article characterizes the concentration of origins of invention from 1976 to 2010, and how these changed over time. The analysis finds pervasive deconcentration in virtually every area related to ICT, but it can explain only a small part of...

Transition in Central Europe is four years old. State firms which dominated the economy are struggling with market forces. A new private sector quickly emerged and has taken hold. Unemployment, which did not exist, is high and still increasing. Will this process of transition accelerate, or slow...

While output declined in virtually all transition economies in the initial years, the speed and extent of the recovery that followed has varied widely across these countries. The contrast between the more and less successful transitions, the latter largely in the former Soviet Union, raises many...
