A large amount of activity in the financial sector occurs in secondary financial markets, where securities are traded among investors without capital flowing to firms. The stock market is the archetypal example, which in most developed economies captures a lot of attention and resources. Is the...

This paper studies optimal contracting under synergies. We define influence as the extent to which effort by one agent reduces a colleague's marginal cost of effort, and synergy to be the sum of the (unidimensional) influence parameters across a pair of agents. In a two-agent model, effort...

This paper identifies a limit to arbitrage that arises from the fact that a firm's fundamental value is endogenous to the act of exploiting the arbitrage. Trading on private information reveals this information to managers and helps them improve their real decisions, in turn enhancing...

The paper develops a model of foreign direct investments (FDI) and foreign portfolio investments (FPI). FDI is characterized by hands-on management style which enables the owner to obtain relatively refined information about the productivity of the firm. This superiority, relative to FPI, comes...

The paper develops a model of foreign direct investments (FDI) and foreign portfolio investments (FPI).The model describes an information-based trade off between direct investments and portfolio investments. Direct investors are more informed about the fundamentals of their projects. This...

FDI investors control the management of the firms, whereas FPI investors delegate decisions to managers. Therefore, direct investors are more informed than portfolio investors about the prospects of projects. This information enables them to manage their projects more efficiently. However, if...

This paper develops a model of a self-fulfilling credit market freeze and uses it to study alternative governmental responses to such a crisis. We study an economy in which operating firms are interdependent, with their success depending on the ability of other operating firms to obtain...

We examine the choice between Foreign Direct Investment and Foreign Portfolio Investment at the level of the source country. Based on a theoretical model, we predict that (1) source countries with higher probability of aggregate liquidity crises export relatively more FPI than FDI, and (2) this...

In this paper, we review three branches of theoretical literature on financial crises. The first one deals with banking crises originating from coordination failures among bank creditors. The second one deals with frictions in credit and interbank markets due to problems of moral hazard and...
