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...

This paper presents a competitive search model focusing on the impact of asymmetric information on credit markets. We show that limited entry by lenders results in endogenous credit rationing, which, in turn, plays a key role in managing adverse selection and prevents the credit market from...

We examine the evolution of spatial house price dispersion during Germany's recent housing boom. Using a dataset of sales listings, we find that house price dispersion has significantly increased, which is driven entirely by rising price variation across postal codes. We show that both price...

In this study we evaluate the effects of low-skilled immigration on small businesses, wages and employment in Germany. We develop a search and matching model with heterogeneous workers, cross-skill matching, and endogenous entry into entrepreneurship. The model is calibrated using German...

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...

We introduce a collective experimentation problem where a continuum of agents choose the timing of irreversible actions under uncertainty and where public feedback from the actions arrives gradually over time. The leading application is the adoption of new technologies. The socially optimal...

We leverage rich data from a prominent online job board in Uruguay to assess directed search patterns in job applications, focusing on posted wages and advertised non-wage amenities. We find robust evidence of directed search based on posted wages in the cross-section, with stark heterogeneity...

We study the effect of finding a job through one's social contact on starting wages. Using combined SOEP-INKAR data for Germany and propensity score analysis - both matching and weighting - we document that referral hiring is associated with a wage penalty of 10%. This penalty is stable over...

When searching for employment, workers consider non-wage job characteristics, such as effort requirements or amenities. We study an environment where unemployed workers search for jobs of different quality in a labor market characterized by directed search. In equilibrium, firms are more likely...

This study estimates and decomposes recruitment elasticity, a key measure of employer market power, across job-matching stages using data from Japan's largest job-matching intermediary. On average, recruitment elasticity is negative but not statistically significantly different from zero....

This paper investigates how worker beliefs and job prospects impact the wages and growth of young firms, as well as the aggregate economy. Building a heterogeneous-firm directed search model where workers gradually learn about firm types, I find that learning generates endogenous wage...

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 linked employer-employee data from Brazil, we document a large gender pay gap due to women working at lower-paying employers. To interpret this fact, we develop an equilibrium search model with endogenous firm pay, amenities, and hiring. We provide a constructive proof of identification of...

The job finding rate declines with the duration of unemployment, but the relative importance of workers' search behavior and employers' recruitment behavior remains unclear. We use monthly search diaries from Swiss public employment offices to shed new light on this issue. Search diaries record...

The Dwarf Mongoose Optimization (DMO) algorithm, inspired by the behaviors and foraging patterns of dwarf mongooses, is a recently formulated swarm-based metaheuristic method emulating the cooperative behavior of mongooses during food searches. The DMO algorithm effectively addresses various...

We introduce a collective experimentation problem where a continuum of agents choose the timing of irreversible actions under uncertainty and where public feedback from the actions arrives gradually over time. The leading application is the adoption of new technologies. The socially optimal...

This paper studies a dynamic quantile model for intertemporal decisions under uncertainty, in which the decision maker maximizes the τ-quantile of the stream of future utilities, for τ ∈ (0,1). We present two sets of contributions. First, we generalize existing results in directions that are...

We propose a standard search and bargaining model with divisible money, in which only the random matching market opens and the generalized Nash bargaining settles each trade. Assuming fixed production costs, we analytically characterize a tractable equilibrium, called a pay‐all equilibrium ,...

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...

We investigate how job displacement affects whom men marry and study implications for marriage market matching theory. Leveraging quasi-experimental variation from Danish establishment closures, we show that job displacement leads men to break up if matched with low-earning women and to re-match...

Recent research documents mounting evidence for sizable and persistent biases in individual labor market expectations. This paper incorporates subjective expectations into a general equilibrium labor market model and analytically studies the implications of biased expectations for wage...
