This paper argues that the introduction of a short-sale constraint in the Arrow-Radner frameworkinvalidates standard definitions of complete and incomplete markets. In this constrained set-up,two threshold values with familiar properties arise.The case of a zero short-sale bound set on some...

In this paper, we document that households' consumption expenditures crucially depend on their expected earnings - even after controlling for realized earnings, wealth and time-invariant unobserved characteristics such as permanent income and over-confidence. To explain this evidence, we develop...

In this paper, we document that households' consumption expenditures depend on their expected earnings - even after controlling for realized earnings and wealth. To explain this evidence, we develop and structurally estimate a standard-incomplete markets model in which rational households...

We investigate whether US households possess advance information about their future income and what this means for consumption insurance. Based on insights from a theoretical model, we propose a new test to detect advance information, which requires only panel data on consumption and income....

This paper provides evidence from a natural experiment on the importance of tacit knowledge that workers have about firms' intangible assets for competition in product and labor markets. First, evidence is presented on product and labor market imperfections across firms in manufacturing and...

Recessions and expansions are often caused or reinforced by developments in private consumption - the largest component of aggregate demand - which, as a result, varies over the business cycle. As such, an accurate measurement of the cyclical component of consumption and an understanding of its...

We analyse a model of equilibrium directed search in a large labour market. Each worker, observing the wages posted at all vacancies, makes a fixed, finite number of applications, a. We allow for the possibility of ex post competition should more than one vacancy want to hire the same worker....

We examine wage competition in a model where identical workers choose the number of jobs to apply for and identical firms simultaneously post a wage. The Nash equilibrium of this game exhibits the following properties: (i) an equilibrium where workers apply for just one job exhibits unemployment...
