Worker movements played a crucial role in making workplaces safer. Workplace safety is costly for firms but increases labour supply. A laissez-faire approach leav- ing safety of workplaces unknown is suboptimal. Safety standards set by better- informed trade unions are output and welfare...

Most empirical studies have estimated a positive union–nonunion “injury gap,†suggesting that unionized workers are more likely than their nonunion counterparts to have a nonfatal occupational injury. Using individual-level panel data for the first time in this type of study,...

Using a repeated cross-section of more than 258,000 residents of 39 European countries covering the period from 1990 to 2012, I study the impact of knowing different foreign languages on income and (for the first time) on unemployment. To help identify causal effects, I also employ a novel...

To which extent does an increase in effectiveness of a public employment agency on the one hand and a reduction of unemployment benefits on the other reduce unemployment? Using the recent labour market reform in Germany we find that an improved agency explains substantial part of the observed...

It is common practice to estimate the volatility-growth link by specifying a standard growth equation such that the variance of the error term appears as an explanatory variable in this growth equation. The variance in turn is modelled by a second equation. Hardly any of existing applications of...
