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...

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...

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...

The empirical evidence on rational inattention lags far behind the theoretical developments: micro evidence on the most immediate consequence of observation costs (the infrequent observation of state variables) is not available in standard datasets. We contribute to filling the gap with two...

A vast literature has investigated the relationship between trust and aggregate economic performance. We investigate the relationship between individual trust and individual economic performance. We find that individual income is hump-shaped in a measure of intensity of trust beliefs available...

We exploit time variation in the degree of development of local credit markets and matched employer-employee data to assess the role of the firm as an internal credit market. In less developed local credit markets firms can offer a flatter wage-tenure profile than firms in more developed credit...

The financial crisis has brought to light diffuse opportunistic behaviour and some serious frauds. Because of this trust towards banks, bankers, brokers and the stock market has collapsed to unprecedented levels and there are so far no signs of recovery. This paper uses survey-based information...
