Awards: Rockwool Foundation Berlin Grant “Integrated Labor Markets, Cross-Border Workers, and Wage Equalization”

A law passed in June 2004 banned the use of gender preferences in job recruiting in Austria. At the time over 40% of openings on the nation’s largest job-board specified a preferred gender. We use data on filled vacancies, merged to employer records, to study how the legal prohibition of gender preferences affected hiring and job outcomes. Prior to the ban, most vacancies with a stated preference signalled stereotypical preferences (e.g., a preference for females at a majority female workplace), but a minority stated preferences to recruit against stereotypes - a subset we call “non-stereotypical” vacancies. Vacancies with a gender preference were very likely (>90%) to be filled by someone of the preferred gender. We develop models based on pre-ban vacancies to predict the probability of specifying a preference for female, males, or neither gender. We then conduct event studies of the effect of the ban on different predicted preference groups. We find that the ban led to a rise in the fraction of women hired for jobs that were likely to be targeted to men (and vice versa), reducing the degree of gender segregation across firms. Partially offsetting this effect, we find a reduction in the success of non-stereotypical vacancies in recruiting workers that would diversify the gender mix of the workplace, and a rise in filling times for these vacancies. For the larger set of stereotypical vacancies, however, vacancy filling times, wages and job durations were largely unaffected by the ban, suggesting that the law had at most small consequences on job match efficiency.

This study presents unique empirical evidence on the importance of moral support for performance. We take advantage of an unusual change in Argentinean football legislation. In August 2013, as a matter of National security, the Argentinean government forced all teams in the first division to play their games with only home team supporters. Supporters of visiting teams were not allowed to be in stadiums during league games. We estimate the effect of this exogenous variation of supporters on team performance, and find that visiting teams are, on average, about 20% more likely to lose without the presence of their supporters. As a counterfactual experiment, we run the analysis using contemporaneous cup games, where the visiting team supporters were allowed to attend, and find no effect of the ban on those games. Moreover, the ban does not seem to bias the decisions of referees, the lineups or the market value of the teams, suggesting that the effect on team performance is due to the loss of moral support rather than other factors. Finally, we find that moral support is more relevant when there is equal power between the two teams, suggesting that moral support compensates the power of monetary resources. This paper provides a proof of concept of moral support as an important non-monetary resource, even in settings with high monetary incentives.

We present acreg, a new command that implements the arbitrary clustering correction of standard errors proposed in Colella et al. (2019, IZA discussion paper 12584). Arbitrary here refers to the way observational units are correlated with each other, we impose no restrictions so that our approach can be used with a wide range of data. The command accommodates both cross-sectional and panel databases and allows the estimation of ordinary least-squares and twostage least-squares coefficients, correcting standard errors in three environments: in a spatial setting using units’ coordinates or distance between units, in a network setting starting from the adjacency matrix, and in a multiway clustering framework taking multiple clustering variables as input. Distance and time cutoffs can be specified by the user, and linear decays in time and space are also optional.

Awards: E4S Grant “transition toward a more resilient, sustainable and inclusive economy”

This paper examines the extent to which changes in international market relative prices lead to shifts in firms’ skill requirements through trade, in the context of an exogenous currency appreciation. On January 15, 2015 the Swiss National Bank unexpectedly abandoned the exchange rate floor with the Euro, causing a 15% increase of the value of the Swiss franc, which remained relatively stable in the subsequent years. This unforeseen appreciation immediately impacted the relative price of trade, creating new incentives and opportunities for import, while simultaneously reducing expected profits for firms exposed to foreign competition. I study how this sharp change in trade conditions affected skill requirements in Switzerland using novel data on trade and labor demand. Specifically, I merge trade data containing information on each single import or export transaction made by Swiss firms to firm-specific job postings data. I find that in the two years after the shock firms with a workforce more exposed to offshorability and automation, increased imports and posted more job ads for highly skilled workers. For these firms, a 10 percent increase in monthly import translates into a 2.1 percent reduction in the routine intensity of their labor demand.
