We document a sharp reversal in electoral participation between the North and the South of Italy after the 1912 enfranchisement which extended voting rights from a limited élite to (almost) all adult males. When voting was restricted to the élite, electoral turnout was higher in the South but...

The ratio of second to fourth digit (2D4D) has been shown to correlate negatively with entrepreneurial skills and financial success. We document that in a sample of entrepreneurs women have a lower 2D4D ratio than men, in sharp contrast with the features of the distribution in random samples....

By using an extensive panel data set of Italian firms, we show empirically that the fraction of firms that engage in a lumpy investment follows a non-normal, double-exponential distribution across region-year. We propose a simple sectoral model that generates the double-exponential distribution...

Using a large sample of retail investors as well as experimental data we find that risk and ambiguity aversion are positively correlated. We show the common link is decision style: intuitive thinkers tolerate more risk and ambiguity than effortful reasoners. One interpretation is that intuitive...

We develop a methodology to collect and analyze data on CEOs’ time use. The idea – sketched out in a simple theoretical set-up – is that CEO time is a scarce resource and its allocation can help us identify the firm’s priorities as well as the presence of governance issues. We follow 94...

We collect information on prenatal testosterone in a large sample of entrepreneurs by measuring the length of their 2th to 4th fingers in face to face interviews. Entrepreneurs with higher exposure to prenatal testosterone (lower second to fourth digit ratio) manage larger firms, are matched...

We use survey data to study American households‘ propensity to default when the value of their mortgage exceeds the value of their house even if they can afford to pay their mortgage (strategic default). We find that 26% of the existing defaults are strategic. We also find that no household...

We contrast two potential explanations of the substantial differences in entrepreneurial activity observed across geographical areas: entry costs and external effects. We extend the Lucas model of entrepreneurship to allow for heterogeneous entry costs and for externalities that shift the...

I provide a test of narrow framing to explain why individuals turn down small positive expected value lotteries. Participants in a large survey have been asked whether they would accept a small lottery of winning 180 euros with probability of 1/2 or losing 100 euros with the same probability. To...

This chapter reviews the recent debate about the role of social capital in economics. We argue that all the difficulties this concept has encountered in economics are due to a vague and excessively broad definition. For this reason, we restrict social capital to the set of values and beliefs...
