We study the repeal of a regulation that imposed maximum wholesale and retail markups for all but five fresh fruits and vegetables. We compare the prices of products affected by regulation before and after the policy change and use the unregulated products as a control group. We find that...

The aim of this paper is to study the effects of product market competition on the explicit compensationpackages that firms offer to their executives. In order to measure the net effect of competition we use twodifferent identification strategies. The first exploits cross sectoral variation in...

This paper uses a difference-in-difference estimator to test whether the introduction of patient choice and hospital competition in the English NHS in January 2006 has prompted hospitals to become more efficient. Efficiency was measured using hospitals' average length of stay (LOS) for patients...

In this paper we investigate the evolution of quality adjusted prices for servers motivated by two facts. First, the productivity acceleration in the US economy since the mid 1990s is closely linked to spread of information technology of which networked computing is a large component. Second,...

This paper contains an empirical analysis demand for "work-group" (or low-end) servers. Servers are at thecentre of many US and EU anti-trust debates, including the Hewlett-Packard/Compaq merger and investigationsinto the activities of Microsoft. One question in these policy decisions is whether...

Case study evidence suggests that exporting firms learn from their clients. But econometric evidence, mostly using exporting and TFP growth, is mixed. We use a UK panel data set with firm-level information on exporting and productivity. Our innovation is that we also have direct data on the...

We provide the first assessment of whether an intensification of product market competition reduces the racial wage gap exactly where taste-based theories predict that competition will reduce labor market discrimination. in economies where employers have strong racial prejudices. We use bank...

We re-consider the impact that regulation of call termination on mobile phones has had on mobile customers' bills. Using a large panel covering 27 countries, we find that the "waterbed" phenomenon, initially observed until early 2006, becomes insignificant on average over the 10-year period,...

This paper presents a pairwise matching model with two-sided information asymmetry to analyse the impact of information costs on endogenous network building and matching by information intermediaries. The framework innovates by examining the role of information costs on incentives for trade...

A two-sided, pair-wise matching model is developed to analyse the strategic interaction between two information intermediaries who compete in commission rates and network size, giving rise to a fragmented duopoly market structure. The model suggests that network competition between information...
