This paper studies how changes in the two key parameters of unemployment insurance—the benefit replacement rate (RR) and the potential benefit duration (PBD)—affect the duration of unemployment. To identify such an effect we exploit a policy change introduced in 1989 by the Austrian government, which affected various unemployed workers differently: a first group experienced an increase in RR; a second group experienced an extension of PBD; a third group experienced both a higher RR and a longer PBD; and a fourth group experienced no change in the policy parameters. We find that unemployed workers react to the disincentives by an increase in unemployment duration, and our empirical results are consistent with the predictions of job search theory. We use our parameter estimates to split up the total costs to unemployment insurance funds into costs due to changes in the unemployment insurance system with unchanged behaviour and costs due to behavioural responses of unemployed workers. Our results indicate that costs due to behavioural responses are substantial.

In Spring 2005, the Ombud for Equal Treatment in Austria launched a campaign notifying employers and newspapers that gender preferences in job ads were illegal. At the time, over 40% of vacancies on the nation’s largest job board stated a gender preference; within a year the rate fell below 5%. We merge job board vacancies and employer records to study how the campaign affected hiring choices and the gender diversity of occupations and workplaces. Using pre-campaign data, we predict the use of gender preferences, then conduct a difference-in-differences analysis of hiring outcomes for vacancies with predicted male or female preferences, relative to those with no predicted preferences. The elimination of explicit gender preferences boosted the share of women hired for jobs that were likely to be targeted to men (and vice versa). At the firm level, we find that the campaign led to a rise in the share of women at firms that were more likely to use male stated gender preferences (SGP’s), and a symmetric increase in the share of men at firms that were likely to use female SGP’s, with no effects on firm survival, employment, or average wages.
