We analyse consumers' search and purchase decisions on an Internet platform. Using a rich dataset on all adverts posted and transactions made on a major French Internet platform (PriceMinister), we show evidence of substantial price dispersion among adverts for the same product. We also show...

We consider a labor market with search frictions in which workers make multiple applications and firms can post and commit to general mechanisms that may be conditioned both on the number of applications received and on the number of offers received by its candidate. When the contract space...

This paper provides a comprehensive assessment of the margins along which firms in Norway respond to increased union density, using legislative changes in the tax deductibility of union dues as a quasi-exogenous shock to firm-level unionization rates. Despite higher personnel costs driven by a...

This paper extends Hall's (1988) methodology to analyse imperfections in both the product and the labour market for firms in the Belgian manufacturing industry over the period 1988-1995. We investigate the heterogeneity in price-cost mark-up and workers' bargaining power parameters among 18...

This paper examines the impact of trade liberalization on firms' product and labor market power. We estimate the prevalence and intensity of firm-level price-cost markups and either wage markups or wage markdowns. We take the dependence between these model-consistent measures of product and...

Married individuals match with spouses who share their occupation more frequently than predicted by chance, suggesting either a preference for same-occupation matches or lower search costs within occupation. To distinguish between these explanations, we use a differences-in-differences strategy...

We investigate the effect of search frictions on labor market sorting by constructing a model which is in line with recent evidence that employers collect a pool of applicants before interviewing a subset of them. In this environment, we derive the necessary and sufficient conditions for sorting...

This paper examines how individuals select into job search in terms of their individual qualifications and perceptions and measures how recruiting additional applicants with a modest job-search subsidy affects selection. I use experimental evidence to examine individuals' decisions to attend and...

Worker sorting into tasks and occupations has long been recognized as an important feature of labor markets. But this sorting may be inefficient if jobseekers have inaccurate beliefs about their skills and therefore apply to jobs that do not match their skills. To test this idea, we measure...

This paper considers competitive search equilibrium in a market for a good whose quality differs across sellers. Each seller knows the quality of the good that he or she is offering for sale, but buyers cannot observe quality directly. We thus have a "market for lemons" with competitive search...
