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....

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 develop a methodology to collect and analyze data on CEO’s 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 CEOs of...

Using information on a large sample of retail investors and experimental data we find that risk aversion and risk ambiguity are correlated: individuals who dislike risk also dislike ambiguity. We show that what links these traits is the way people handle decisions. Intuitive thinkers are less...

We study the life cycle of portfolio allocation following for 15 years a large random sample of Norwegian households using error-free data on all components of households’ investments drawn from the Tax Registry. Both, participation in the stock market and the portfolio share in stocks, have...

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...

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...

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...

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 atter 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...
