In recent contributions, von Weizsäcker (2014) and Summers (2014) maintain that mature economies accumulate too much capital. They suggest large and lasting public deficits as a remedy. This study argues that overaccumulation cannot occur in an economy with land. It presents novel data of aggregate land values, analyzes the issue within a stochastic framework and conducts an empirical test of overaccumulation.

According to the literature on traditional banking, lenders often discriminate against female borrowers. However, studies of peer-to-peer lending in the United States find that female borrowers have better chances of obtaining funds than do males. We provide evidence on the success of female borrowers at a large German peer-to-peer lending platform. Our results show that there is no effect of gender on the individual borrower’s chance to receive funds on this platform, ceteris paribus. Several robustness checks confirm this finding. Hence, female discrimination seems to be eased by the ‘wisdom of the lending crowd’.

We investigate the relationship between life satisfaction and mortality using the German Socio-Economic Panel, which allows us to follow around 15,000 people for more than two decades. Seventeen per cent of the respondents surveyed in 1984 died between 1984 and 2007. After controlling for initial health conditions, we find that people’s life satisfaction at the beginning of the survey is deeply linked to their life expectancy: a ten per cent increase in life satisfaction is connected to a four per cent decline in the probability of death in the period studied. The relationship between life satisfaction and mortality is stronger for the married and the men but life satisfaction does not matter for the women. We find some suggestive evidence that links between life satisfaction and mortality could be operating via accidents and mental health. Finally, we show that the life satisfaction measured in 1984 extends to the rest of life: people who were happier in 1984 more frequently experienced high levels of happiness in the rest of their lives. These results suggest that life satisfaction is a powerful risk-factor for later mortality and is more predictive of mortality than a host of other variables.

This study evaluates whether economists support economic policies such as free trade because they deem them to be good for their home country or because they increase global welfare. In a telephone survey, 100 German economists were asked to judge different policy proposals dealing with immigration, military exports and climate policy. Our results show that the acceptance of the policy proposals is strongly influenced by national efficiency judgements. In contrast, global efficiency judgements exert no significant positive effect on policy proposal acceptance. These effects even hold for economists who self-reported a global perspective in the assessment of the policy proposals. These judgements might be based on the potentially erroneous assumption that their policy judgements, taken from a national perspective, are consistent with global interests.
