Using data on applied-for jobs for the universe of Danish UI recipients, we examine variation in job search behavior both across individuals and over time during unemployment spells. We find large differences in the level of applied-for wages across individuals but over time all individuals adjust wages downward in the same way. The decline in applied-for wages over time is descriptively small but economically important in standard models of job search. We find similar results when examining variation in the non-wage characteristics of applied-for jobs and in the search methods used to find them. We discuss implications for theory.

We study how online job search advice affects job search behavior and labor market outcomes of unemployed workers. In a large-scale field experiment embedded in the online platform of the Danish public employment service, we provide job seekers with vacancy information and occupational recommendations. Using a two-stage randomized design with regionally varying treatment intensities, we examine both direct effects of advice and treatment spillovers. We find that advice significantly increases employment and earnings when provided to a limited share of job seekers. As treatment intensity rises, these effects diminish and eventually disappear. The decline is driven by negative spillovers among treated job seekers, consistent with increased congestion in the occupations toward which job seekers redirect their search. Spillover effects on untreated job seekers are heterogeneous and depend on how advice alters occupation-specific competition in local labor markets.
