he classic search models assume that consumers adhere to a particular method of search (sequential or non-sequential) and that they know the true price distribution. In this paper, we evaluate how well the search cost estimates from classic models predict search outcomes - the amount of search...

We investigate how reducing information costs through forced experimentation with postal voting, while holding administrative rules fixed, affects subsequent voting behavior. Leveraging a natural experiment during Bavaria’s 2020 Mayoral Elections and drawing on municipality-level...

This paper examines the welfare implications of priority service in a frictional search environment with heterogeneous outside options. Priority search facilitates expedited matching with public options in the market by charging a service premium. Our main analysis demonstrates that a...

College graduates tend to marry each other. We use detailed Norwegian data to show that strong assortativity further arises by institution and field of study, especially among high earners from elite programs. Admission discontinuities reveal that enrollment itself, rather than selection,...

Whether and how workers search on the job depends on their beliefs about pay and working conditions in other firms. Yet little is known about workers' knowledge of outside pay. We use a large-scale survey of full-time German workers, linked to their Social Security records, to elicit pay...

This paper studies how dynamic changes in the search environment affect consumer search and purchase behavior. We develop a dynamic model that incorporates a non-stationary search environment and propose a feasible estimation procedure to estimate its parameters. We apply our model and...

We study the determination of market power at the firm and industry levels when heterogeneous firms compete for sales to ex ante homogeneous buyers in a market with both directed and random search and free entry of firms that differ in productivity. Search and the distribution of productivity...

We study markets in which potential buyers engage in costly search to find a good deal. Our novel solution concept for prices builds upon the idea that any movement in a firm's price is followed by an opportunity for its competitors to respond with special offers. This mechanism selects the...

We study price discrimination by a monopolistic seller that endogenously produces a market segmentation at a cost, and question the efficiency of the production of market segmentations led by private incentives. We show that the efficient market segmentation gives all the gains in total surplus...

We study a static bilateral trade setting with moral hazard, where a seller privately chooses quality and a buyer may pay to verify it. We show that buyer-side information acquisition can lead to informational hold-up through a mechanism wecall surplus squeezing: precise verification enables the...

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...

The rapid development of digital finance has transformed traditional financial institutions. We investigate the effect and economic consequences of bank digital transformation on corporate financial constraints using data from China. The results show that bank digital transformation alleviates...

We study the effect of diminishing search frictions in markets with adverse selection by presenting a model in which agents with private information can simultaneously contact multiple trading partners. We highlight a new trade-off: facilitating contacts reduces coordination frictions but also...

This paper considers a random search model where some locations provide sellers with better chances of meeting many buyers than other locations (for example popular shopping streets or the first page of a search engine). When sellers are heterogeneous in terms of the quality of their product...
