The underpricing of the shares sold through Initial Public Offerings (IPOs) is generally explained with asymmetric information and risk. We complement these traditional explanations with a new theory. Investors who buy IPO shares are also concerned by expected liquidity and by the uncertainty...

High-tech start-ups get external finance and guidance mostly from venture capitalists and/or business angels. We identify a simultaneous double moral hazard for the management style of entrepreneurs and the decision to advise the firm for financiers. We embed this relationship into the financial...

Speculators often advertise arbitrage opportunities in order to persuade other investors and thus accelerate the correction of mispricing. This induces under-diversification: a risk-averse arbitrageur will optimally advertise only one of several mispriced assets, and overweigh it in his...

This paper investigates the importance that market regulation and financial imperfections have in firm size. We analyse institutions affecting labour market as Employment Protection Laws (EPL) and Product Market Regulation (PMR). Moreover, we study the effects of these institutions on firm...

The costs of enforcing contracts is a key determinant of market performance. We document this point with reference to the credit market. We start by presenting a model of opportunistic debtors and inefficient courts. According to the model, improvements in judicial efficiency reduce credit...

Many argue that the primary function of banks is to provide cheap credit, and to this effect advocate strict protection of creditor rights. But banks serve another important function: through project screening, they can improve the allocation of capital across projects. In this paper we show...

We explore the pattern of elderly homeownership using microeconomic surveys of 17 OECD countries. In most countries the survey is repeated over time, permitting construction of an international dataset of repeated cross-sectional data, merging 59 national household surveys on about 300,000...

Many studies show that most people are not financially literate and are unfamiliar with even the most basic economic concepts. However, the evidence on the determinants of economic literacy is scant. This paper uses international panel data on 55 countries, merging indicators of economic...

In this paper we focus on poor financial literacy as one potential factor explaining lack of portfolio diversification. We use the 2007 Unicredit Customers’ Survey, which has indicators of portfolio choice, financial literacy and many demographic characteristics of investors. We first propose...

Rational investors perceive correctly the value of financial information. Investment in information is therefore rewarded with a higher Sharpe ratio. Overconfident investors overstate the quality of their own information, and thus attain a lower Sharpe ratio. We contrast the implications of the...
