When vacancies are filled, the ads that were posted are often not withdrawn, creating "phantom" vacancies. The existence of phantoms implies that older job listings are less likely to represent true vacancies than are younger ones. We assume that job seekers direct their search based on the...

This paper examines the impact of diagnostic efficiency on the COVID-19 pandemic. Using an exogenous policy on diagnostic confirmation, we show that a one- day decrease in the time taken to confirm the first case in a city publicly led to 9.4% and 12.7% reductions in COVID-19 prevalence and...

This paper contributes to the literature on public health communication by studying how the framing of a message relaying the forecast impact of COVID-19 prevention measures affects compliance behaviour amongst both the young and old. A representative sample of survey respondents in the UK and...

This paper examines how individuals select into job search in terms of their individual qualifications and perceptions and measures how recruiting additional applicants with a modest job-search subsidy affects selection. I use experimental evidence to examine individuals' decisions to attend and...

Bayesian Updating is the dominant theory of learning in economics. The theory is silent about how individuals react to events that were previously unforeseeable or unforeseen. Recent theoretical literature has put forth axiomatic frameworks to analyze the unknown. In particular, we test if...

SMS information campaigns are increasingly used for policy. We conduct a field experiment to study information sharing through mobile phone messages. Subjects are rural households in Mozambique who have access to mobile money. In the baseline intervention, subjects receive an SMS containing...

We study how the transparency of welfare systems affects labor market outcomes of unemployed workers in a large-scale field experiment. Our low-cost information intervention uses a personalized online tool that informs benefit recipients about their personal risk of a benefit reduction when not...

Job seekers often face substantial information frictions related to potential job quality. This is especially true in international labor markets, where intermediaries match prospective migrants with employers abroad. We conducted a randomized trial in Indonesia to explore how information about...

We survey samples of German firms and households to document novel stylized facts about the extent of information frictions among the two groups. First, firms' expectations about macroeconomic variables are closer to expert forecasts and less dispersed than households', consistent with higher...

We investigate in a laboratory setting whether revealing information on the intelligence of both players affects behavior in repeated games. We study the Prisoners' Dilemma (PD) and Battle of Sexes (BoS) as they cover a large set of the interesting scenarios generated by repeated games of two...
