What is the economic role of mergers? We investigate this issue by performing a comparative study of mergers and other forms of corporate investment, at the industry and firm levels. In our framework, merger activity is motivated by both firm- and industry-level forces that can generally be...

The essence of structured finance activities is the pooling of economic assets (e.g. loans, bonds, mortgages) and subsequent issuance of a prioritized capital structure of claims, known as tranches, against these collateral pools. As a result of the prioritization scheme used in structuring...

This paper develops a new model of transaction costs, arising as the rents that a monopolistic market maker is able to extract from impatient investors. The mechanism for trade is a limit order, and immediacy is supplied when the limit order is executed. We show that limit orders are American...

This document describes how interactive market simulations are used to teach finance in the Dynamic Markets course at Harvard Business School. The course is organized around hands-on application in a wide variety of capital market settings with the goal of producing experts in financial...

This paper examines asset fire sales, and institutional price pressure more generally, in equity markets, using market prices of mutual fund transactions caused by capital flows from 1980 to 2003. Funds experiencing large outflows (inflows) tend to decrease (increase) existing positions, which...

We document that the risks and pre-fee returns of broad hedge fund indices can be accurately matched with simple equity index put writing strategies, which provide monthly liquidity and complete transparency over their state-contingent payoff profiles. This nonlinear risk exposure combines with...

This paper models transaction costs as the rents that a monopolistic market maker extracts from impatient investors who trade via limit orders. We show that limit orders are American options. The limit prices inducing immediate execution of the order are functionally equivalent to bid and ask...

This paper examines the trading behavior of professional investors around 2,130 mergers announced between 1994 and 2000. We find considerable support for the existence of price pressure around mergers caused by uninformed shifts in excess demand, but that these effects are short-lived,...

The central insight of asset pricing is that a security's value depends both on its distribution of payoffs across economic states and on state prices. In fixed income markets, many investors focus exclusively on estimates of expected payoffs, such as credit ratings, without considering the...
