This theoretical study rigorously investigates how generative artificial intelligence reshapes decision-making in social entrepreneurship by modeling the opportunity search process through the lens of optimal stopping theory. Social entrepreneurs often face high uncertainty and resource...

Belgium's 2016 payroll tax exemption for first-time employers triggered a sharp increase in firms hiring their first worker but little growth among larger firms. To account for this pattern, we develop and estimate a directed search model - with discrete hiring, firm heterogeneity, and...

In a field experiment with 9,000 Danish job seekers, we study how unemployed workers' wage expectations affect job search and re-employment. In our survey, we generate exogenous variation in respondents' wage expectations by informing a random half of them about re-employment wages of comparable...

Heterogeneous search costs enable price discrimination, which I study in the canonical Wolinsky (1986) sequential search setting. Firms observe a public signal of a consumer's search cost before posting a personalized price. The welfare effects of search-cost-based price discrimination depend on...

We present a tractable, hybrid framework that nests random and perfectly directed search, in which workers are more likely to direct their search toward submarkets with higher returns, while still searching in inferior submarkets with positive probability. The choice of submarket is governed by...

We study mean-field games of optimal stopping (OS-MFGs) and introduce an entropy-regularized framework to enable learning-based solution methods. By utilizing randomized stopping times, we reformulate the OS-MFG as a mean-field game of singular stochastic controls (SC-MFG) with entropy...

Wage information is rare in job adverts, yet crucial for search. To study this information friction, we run a field experiment with real vacancies, randomly adding or withholding wage information. Disclosing wages does not change average application volumes. Instead, it amplifies the wage...

This paper applies some of the key insights of dynamic discrete choice models to continuous-time job search models. Our framework incorporates preference shocks into search models, resulting in a tight connection between value functions and conditional choice probabilities. In this environment,...

This paper connects classical preference theory to quantitative job search and savings models. We treat job acceptance as a choice between stochastic income lotteries. By integrating Decreasing Absolute Risk Aversion (DARA) and Prudence (DAP), we derive five contributions. First, we prove the...

We show that workers use outside options to extract match-specific rents. Exploiting unique data on worker skills, we construct a measure of match quality based on the relationship between workers’ multidimensional skills and job-specific skill requirements. Focusing on job-to-job movers, we...

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...

This paper examines how caseworkers influence job finding rates and job quality. To rule out selection effects, I exploit that caseworkers are assigned based on the jobseekers’ month of birth in some offices of the Austrian public employment service. Combining administrative data on...

I study tâtonnement processes in a matching market without transfers. In each period, schools set cutoffs, i.e. the preference ranks of the least preferred students they are willing to admit, and students accept their most preferred offers. Cutoffs are adjusted on the basis of demand-supply...

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...

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 present an experimental study of decentralized two‐sided matching markets with no transfers. Experimental participants are informed of everyone's preferences and can make arbitrary nonbinding match offers that get finalized when a period of market inactivity has elapsed. Several insights...

The effects on criminal behaviour of raising the minimum wage for those aged 25 and over in the United Kingdom are analysed, using data on police stop and search activities. A 1% increase in the minimum wage raises the fraction of people stopped by the police by 2.96%, the fraction of people...

We develop a model where heterogeneous agents choose whether to engage in onthe-job search (OJS) to improve labor income. The model accounts for untargeted microdata patterns: fiscal incentives affect job-to-job mobility and wage growth of stayers-but not leavers-across the income distribution,...

In the United States, workers whose past earnings were below a threshold are generally ineligible for unemployment insurance (UI), creating a discontinuous jump in the value of being unemployed. Using a regression discontinuity design with administrative panel data, we estimate a sizable local...

This report replicates the study by Belot et al. (2022), which investigates how posted wages affect labor supply through a field experiment using a job platform with varying wage postings. The paper's main finding is that a higher wage increases job seekers' interest in a vacancy, a result at...
