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 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...

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...

Using data on over 3.5 million firm-bank relationships, I document new facts suggesting that search frictions are pervasive in the market for small business loans. Motivated by this evidence, I develop a theory of firm-bank matching where firms incur costs to search for banking partners. The...

We develop and estimate a search model in which identical consumers trade with price-setting firms that differ in productivity. In the model, equilibrium distributions of both prices and markups are non-degenerate and continuous with a firm's price decreasing in its productivity. Variation in...

Assessing the quantitative relevance of match quality and search frictions for house price dispersion is key to understanding house price formation and the importance of uninsurable housing wealth shocks. In this paper, we use a unique auction-level data set from Norway, combined with a...

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...

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 consumer search literature mostly considers independently distributed products. In contrast, I study a model of directed search with infinitely many products whose valuations are correlated through shared attributes. I propose a tractable, systematic, history-dependent scoring system based...

I analyze a model of directed search in which a consumer inspects a finite number of products sharing attributes with each others. The consumer discovers her valuation for the attributes of the inspected products and adapts her search strategy based on what she has learned. The consumer...

In many markets, firms offering low-quality goods are more prominent than firms offering high-quality goods. Then, consumers are perfectly informed about the good of the prominent low-quality firm but incur search costs to bring the high-quality good of a competitor to mind. We analyze under...

We propose a model that reconciles microeconomic evidence of frequent and large price changes with sizable monetary non-neutrality. Firms incur separate lump-sum costs to change prices and to gather and process some information about marginal costs. Additional relevant information is...

We tested the influence of time pressure and to what extent time pressure interacts with the contextual factors ("payoff scheme" and "level of costs for information that can be acquired") in three laboratory experiments. Participants had to decide how many pieces of information they wanted to...

This research investigates the profound influence of information friction on housing market outcomes in Beijing, China. Leveraging an extensive dataset of administrative micro-level housing resale transactions, we employ a boundary discontinuity design and difference-in-differences model to...

When considering whether or not to buy a product, the consumer can often evaluate different attributes of it. Due to limited attention, the consumer often can only search for information about one attribute at a time. Assuming that a product has two attributes, we study the optimal search...

To describe underinvestment in green assets, we employ a combined learning-investment model to rationalize portfolio underdiversification. Building upon the literature of investment under incomplete information, we derive a Merton-type stochastic continuous-time learning-investment model, where...

In many economic situations, such as job search and online shopping, agents are sequentially searching for information to choose one of a few options. Information revealed through their search process affects the eventual choice outcomes of such economies. This study explores a Bayesian...

A general equilibrium model is presented in which individuals can learn about the realization of a payoff relevant latent random variable at a cost or extract information embedded in prices. While only partially revealing the realization of the latent random variable, equilibrium prices fully...

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...
