Workers in less secure jobs are often paid less than identical-looking workers in more secure jobs. We show that this lack of compensating differentials for unemployment risk can arise in equilibrium when all workers are identical and firms differ only in job security (i.e. the probability that...

We investigate the role of complementarities in production and skill mobility across cities. We propose a general equilibrium model of location choice by heterogeneously skilled workers, and consider different degrees of complementarities between the skills of workers. The nature of the...

We propose a theory of firm production that requires diverse inputs. We show that in a competitive labor market, firms differ in their skill composition. Organizations with higher Total Factor Productivity (TFP) are larger and hire from a broader range of skills. Technological progress leads to...

Many markets rely on information intermediation to sustain cooperation between large communities. We identify a key trade-off in costly information intermediation: intermediaries can create trust by incentivizing information exchange, but with too much information acquisition, intermediation...

In this paper, we show that information trade has similar characteristics to a natural monopoly, where competition may be detrimental to efficiency due either to the duplication of direct costs or the slowing down of information dissemination. We present a model with two large populations in...

We develop and test a model linking the duration of financial fraud to information produced by auditors and analysts and efforts by managers to conceal the fraud. Our empirical results suggest fraud termination is more likely in the quarter following the release of audited financial statements,...
