Has economic research been helpful in dealing with the financial crises of the early 2000s? On the whole, the answer is negative, although there are bright spots. Economists have largely failed to predict both crises, largely because most of them were not analytically equipped to understand...

This paper distils three lessons for bank regulation from the experience of the 2009-12 euro-area financial crisis. First, it highlights the key role that sovereign debt exposures of banks have played in the feedback loop between bank and fiscal distress, and inquires how the regulation of...

We investigate the determinants of firms’ implicit employment and wage insurance to employees against industry-level and idiosyncratic shocks. We rely on differences between family and non-family firms to identify the supply of insurance, and between national public insurance programs to gauge...

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...

We present a model where firms compete for scarce managerial talent ("alpha") and managers are risk-averse. When managers cannot move across firms after being hired, employers learn about their talent, allocate them efficiently to projects and provide insurance to low-quality managers. When...

We present a model in which issuers of asset backed securities choose to release coarse information to enhance the liquidity of their primary market, at the cost of reducing secondary market liquidity or even causing it to freeze. The degree of transparency is inefficiently low if the social...

How does finance affect employment and inter-industry job reallocation? We present a model that predicts that financial development (i) increases employment and/or labor productivity and wages, with a smaller impact at high levels of the equilibrium wage and financial development; (ii) may...

This paper examines the role of credit rating agencies in the subprime crisis that triggered the 2007-08 financial turmoil. We focus on two aspects of ratings that contributed to the boom and bust of the market for structured debt: rating inflation and coarse information disclosure. The paper...

In the last decade, the increased competition between European stock exchanges has reduced the cost of trading and increased the variety of trading mechanisms. The London Stock Exchange, which initiated the competition in 1986 by setting up the SEAQ-I market, attracted considerable trading...

We analyze how the law and its enforcement affect equity market equilibrium. Improvements in the legal system, while invariably associated with broader equity markets, have different effects on equity returns depending on the institutional change considered and on the degree of international...
