This paper develops a model in which market structure is determined endogenously by the choice of intermediation mode. We consider two representative business modes of intermediation that are widely used in real-life markets: one is a middleman mode where an intermediary holds inventories which...

This study uses survey data on small business loans granted 2022 -2023 to explore racial disparities in the terms of loans to small firms. Similar data has not been available since the 2003 Survey of Small Business Finances (SSBF). We find that for Hispanic-, Asian American- and Black-owned...

We provide evidence that long-term relationships between trading parties emerge endogenously in the absence of third party enforcement of contracts and are associated with a fundamental change in the nature of market interactions. Without third party enforcement, the vast majority of trades are...

This paper investigates price-setting for truly homogenous products sold in markets without any formal trade barriers. We use data from IKEA, a furniture company selling identical products in an identical shopping environment in different EU countries. We get four remarkable outcomes: 1) The law...

While most empirical analysis of prediction markets treats prices of binary options as predictions of the probability of future events, Manski (2004) has recently argued that there is little existing theory supporting this practice. We provide relevant analytic foundations, describing sufficient...

Anecdotal, empirical, and experimental evidence suggests that offering extrinsic rewards for certain activities can reduce people's willingness to engage in those activities voluntarily. We propose a simple rationale for this 'crowding out' phenomenon, using standard economic arguments. The...

A striking feature of the past few decades has been the development of wage-determination models that assume that labour markets are imperfectly competitive. This paper discusses two such models (trade unions and oligopsony), although there are many more. It also asks if imperfectly competitive...

At first blush, most advances in labour demand were achieved by the late 1980s. Since then progress might appear to have stalled. We argue to the contrary that significant progress has been made in understanding labour market frictions and imperfections, and in modelling search behaviour and...

Although market concentration is one of the main impediments to productivity growth globally, data constraints have limited its analysis to developed countries or cross-country studies based on definitions of market concentration across nations and industries. This paper takes advantage of a...
