The paper studies the causes of the current financial crisis and considers proposals for mitigation and prevention of future crises. The crisis is was the product of a ‘perfect storm’ bringing together a number of microeconomic and macroeconomic pathologies. Among the microeconomic systemic...

We develop a model of financially constrained arbitrage, and use it to study the dynamics of arbitrage capital, liquidity, and asset prices. Arbitrageurs exploit price discrepancies between assets traded in segmented markets, and in doing so provide liquidity to investors. A collateral...

We develop a dynamic model of liquidity provision, in which hedgers can trade multiple risky assets with arbitrageurs. We compute the equilibrium in closed form when arbitrageurs' utility over consumption is logarithmic or risk-neutral with a non-negativity constraint. Liquidity is increasing in...

This Paper constitutes a first attempt to analyse the impact of the emergence of new funds on portfolio decisions of mutual fund managers who are evaluated on the basis of relative performance. Recent theoretical literature has pointed to the inefficiencies in portfolio selection caused by...

We examine the risk-return characteristics of a rolling portfolio investment strategy where more than six thousand Nasdaq initial public offering (IPO) stocks are bought and held for up to five years. The average long-run portfolio return is low, but IPO stocks appear as ‘longshots’, as...

Recent empirical work suggests a strong connection between the incentives money managers are offered and their risk-taking behavior. We develop a general model of delegated portfolio management, with the feature that the agent can control the riskiness of the portfolio. This represents a...

There is now extensive empirical evidence showing that fund managers have relative performance objectives and adapt their investment strategy in the last part of the calendar year to balance their performance in the early part of the year. However, emphasis was put on returns in excess of some...

This paper takes a systematic look at the portfolio choice problem faced by investment banks or funds investing in transition economies. We relate the performance of projects in the transition economies to the broader macroeconomic and international environment, which affect the project through...

We analyze incentives to develop entrepreneurial ideas for venture capitalists (VCs) and incumbent firms. If VCs are sufficiently better at judging an idea's value and if it is sufficiently more costly to patent low than high value ideas, VCs acquire valuable ideas, develop them beyond the level...

This paper investigates how patent applications and grants held by new ventures improve their ability to attract venture capital (VC) financing. We argue that investors are faced with considerable uncertainty and therefore rely on patents as signals when trying to assess the prospects of...
