Abstract
We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous findings, our dynamic models indicate an inverse u-shaped association between bmi and wages. As the implied maximum occurs in the ‘overweight’ category, the positive trend in weight may not yet constitute a major limitation to productivity. Further investigation points out a stronger association among young workers and workers with jobs that are less protected. Work satisfaction of young workers is associated with bmi beyond the effect of earnings.

The Role of Entrepreneurship in US Job Creation and Economic Dynamism

Abstract
An optimal pace of business dynamics—encompassing the processes of entry, exit, expansion, and contraction—would balance the benefits of productivity and economic growth against the costs to firms and workers associated with reallocation of productive resources. It is difficult to prescribe what the optimal pace should be, but evidence accumulating from multiple datasets and methodologies suggests that the rate of business startups and the pace of employment dynamism in the US economy has fallen over recent decades and that this downward trend accelerated after 2000. A critical factor in accounting for the decline in business dynamics is a lower rate of business startups and the related decreasing role of dynamic young businesses in the economy. For example, the share of US employment accounted for by young firms has declined by almost 30 percent over the last 30 years. These trends suggest that incentives for entrepreneurs to start new firms in the United States have diminished over time. We do not identify all the factors underlying these trends in this paper but offer some clues based on the empirical patterns for specific sectors and geographic regions.

A Weighty Issue Revisited: The Dynamic Effect of Body Weight on Earnings and Satisfaction in Germany
Frieder Kropfhäußer, Marco Sunder
Abstract
We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous literature, the dynamic models indicate that there is an inverse u-shaped association between bmi and wages among young workers. Among young male workers, work satisfaction is affected beyond the effect on earnings. Our finding of an implied optimum bmi in the overweight range could indicate that the recent rise in weight does not yet constitute a major limitation to productivity.

Is There a Gap in the Gap? Regional Differences in the Gender Pay Gap

Abstract
In this paper, we investigate regional differences in the gender pay gap both theoretically and empirically. Within a spatial model of monopsonistic competition, we show that more densely populated labour markets are more competitive and constrain employers’ ability to discriminate against women. Utilizing a large administrative data set for western Germany and a flexible semi-parametric propensity score matching approach, we find that the unexplained gender pay gap for young workers is substantially lower in large metropolitan than in rural areas. This regional gap in the gap of roughly 10 percentage points remained surprisingly constant over the entire observation period of 30 years.
