We examine the business model of traditional commercial banks in the context of their co-existence with shadow banks. While both types of intermediaries create safe "money-like" claims, they go about this in different ways. Traditional banks create safe claims by relying on deposit insurance,...

We build a model that helps explain why increases in liquidity - such as lower bid-ask spreads, a lower price impact of trade, or higher share turnover - predict lower subsequent returns in both firm-level and aggregate data. The model features a class of irrational investors, who underreact to...

This paper presents estimates of the systematic risk of the debt in public leveraged recapitalizations. We calculate the systematic risk of the debt as a function of the difference between the systematic equity risk before and after the recapitalization. The increase in equity risk is...

We explore the consequences for corporate financial policy that arise when investors exhibit inertial behavior. One implication of investor inertia is that, all else equal, a firm pursuing a strategy of equity-financed growth will prefer a stock-for-stock merger to greenfield investment financed...

This paper surveys recent work that relates to the "lending" view of monetary policy transmission. It has three main goals: 1) to explain why it is important to distinguish between the lending and "money" views of policy transmission; 2) to outline the microeconomic conditions that are needed to...

This essay surveys the body of research that asks how the efficiency of corporate investment is influenced by problems of asymmetric information and agency. I organize the material around two basic questions. First, does the external capital market channel the right amount of money to each firm?...

We develop a model that clarifies the respective advantages and disadvantages of academic and private-sector research. Our model assumes full protection of intellectual property rights at all stages of the development process, and hence does not rely on lack of appropriability or spillovers to...

Standard models of informed speculation suggest that traders try to learn information that others do not have. This result implicitly relies on the assumption that speculators have long horizons, i.e, can hold the asset forever. By contrast, we show that if speculators have short horizons, they...

We study the implications of learning in an environment where the true model of the world is a multivariate one, but where agents update only over the class of simple univariate models. If a particular simple model does a poor job of forecasting over a period of time, it is eventually discarded...

Theory suggests that, in the presence of local bias, the price of a stock should be decreasing in the ratio of the aggregate book value of firms in its region to the aggregate risk tolerance of investors in its region. We test this proposition using data on U.S. Census regions and states, and...
