This paper shows that larger auctions are more efŽ cient than smaller ones, but that despite this scale effect, two competing and otherwise identicalmarkets or auction sites of different sizes can coexist in equilibrium. We Ž nd that the range of equilibrium market sizes depends on the aggregate buyer–seller ratio, and also whether the markets are especially thin. (JEL: D44, L11)

We study whether the effects on registered manufacturing output of dismantling the License Raj — a system of central controls regulating entry and production activity in this sector — vary across Indian states with different labor market regulations. The effects are found to be unequal across Indian states with different labor market regulations. In particular, following delicensing, industries...

This paper analyzes the evolution of firm size distribution in the U.S. manufacturing industries over 35 years from 1963 to 1997. Firm size distribution undergoes systematic changes, the magnitude and the direction of which depend on whether an industry experiences a phase of growth, shakeout, stability, or decline. The observed patterns have implications for the theories of industry dynamics a...

Cross sectional estimation of convergence regressions is known to be hazardous if there is convergence towards heterogeneous steady state values. In this paper, Monte Carlo methods are used to investigate the implications of this parameter heterogeneity problem. The cross sectional and pooled OLS estimators are compared with a panel estimator which is unaffected by heterogeneity. If there is he...

This paper formalizes an empirically implementable framework for the definition of local antitrust markets in retail markets. This framework rests on a demand model that captures the trade-off between distance and pecuniary cost across alternative shopping destinations within local markets. The paper develops, and presents estimation results for, an empirical demand model at the store level for...

In this paper we argue that two important causes of welfare losses in oligopolistic markets have been neglected. We show that in models where location is endogenous, welfare losses arising from wrong locations or from lack of market coverage may be substantial despite firms competing in prices. In contrast, welfare losses arising from quality choice are modest but they might vary discontinuousl...

Competition authorities have a growing interest in assessing the effects of partial ownership arrangements. We show that the effects of such agreements on competition and welfare depend on the intensity of competition in the market and on the firms’ governance structure. When assessing the effects of partial ownership, competition policy has to consider both the financial interest and level of ...

We argue that there exists a problem of adverse selection in the provision of advertising which makes it impossible to establish direct markets for it. The media are regarded as intermediaries that can channel advertising and allocate it efficiently by screening consumers. This role of media may result in excessive quality and prices of media products. These distortions will be more severe if c...

We use microdata collected at the border and store to characterize price impact of recent US trade policy on importers, exporters, consumers. At border, import tariff pass-through is much higher than exchange rate pass-through. Chinese exporters did not lower their dollar prices by much, despite appreciation dollar. By contrast, significantly lowered affected foreign retaliatory tariffs. In sto...
