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)

Abstract. This paper presents an updated estimation of the bottom-up global surface seawater dimethyl sulfide (DMS) climatology. update, called DMS-Rev3, is third its kind and includes five significant changes from last climatology, L11 (Lana et al., 2011), that was released about a decade ago. The first change inclusion new observations have become available over decade, creating database 873 ...

In theory, regulators concerned about inequality will deviate from efficient two-part tariffs, charging lower-than-efficient fixed monthly fees and higher-than-efficient per-kilowatt-hour prices. To quantify that relationship, we develop a measure of the redistributive extent utility tariffs: “electric Gini.” Utilities with higher electric Ginis shift more costs households using relatively litt...

This paper studies the interaction between barriers to firm entry and distortions allocative efficiency in a standard model of dynamics. We derive strategy infer based on cross-country differences size distribution idiosyncratic distortions. The inferred resemble regulation-based indicators advanced economies but are substantially higher middle- low-income countries. Regulation-based cannot acc...

The large and growing industry of price comparison websites (PCWs) or ‘web aggregators’ is poised to benefit consumers by increasing competitive pricing pressure on firms acquainting shoppers with more prices. However, these sites also charge for sales, which feeds back raise I investigate the impact introducing PCWs a market homogeneous good. find that single PCW increases prices all consumers...

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...
