ABSTRACT This paper asks how well different organizational structures perform in terms of generating information about investment projects and allocating capital to these projects. A decentralized approach‐with small, single‐manager firms‐is most likely to be attractive when information about projects is “soft” and cannot be credibly transmitted. In contrast, large hierarchies perform better when information can be costlessly “hardened” and passed along inside the firm. The model can be used to think about the consequences of consolidation in the banking industry, particularly the documented tendency for mergers to lead to declines in small‐business lending.

ABSTRACT Momentum effects in stock returns need not imply investor irrationality, heterogeneous information, or market frictions. A simple, single‐firm model with a standard pricing kernel can produce such effects when expected dividend growth rates vary over time. An enhanced model, under which persistent growth rate shocks occur episodically, can match many of the features documented by the empirical research. The same basic mechanism could potentially account for underreaction anomalies in general.

If arbitrage is costly and noise traders are active, asset prices may deviate from fundamental values for long periods of time. We use a sample of 158 closed‐end funds to show that noise‐trader sentiment, as proxied by retail‐investor flows, leads to fluctuations in the discount. Nevertheless, we reject the hypothesis that noise‐trader risk is the cause of the long‐run discount. Instead we find that funds which are more difficult to arbitrage have larger discounts, due to: (1) the censoring of the discount by the arbitrage bounds, and (2) the freedom of managers to increase charges when arbitrage is costly.

ABSTRACT Firms differ in the extent to which they “pass through” changes in exchange rates into foreign currency prices and in their “exposure” to exchange rates—the responsiveness of their profits to changes in exchange rates. Because pricing affects profitability, a firm's pass‐through and exposure should be related. This paper develops models of exporting firms under imperfect competition to study these related phenomena. From these models we derive the optimal pass‐through decisions and the resulting exchange rate exposure. The models are estimated on eight Japanese export industries using both the price data pass‐through and financial data for exposure.

ABSTRACT What ties together the traditional commercial banking activities of deposit‐taking and lending? We argue that since banks often lend via commitments, their lending and deposit‐taking may be two manifestations of one primitive function: the provision of liquidity on demand. There will be synergies between the two activities to the extent that both require banks to hold large balances of liquid assets: If deposit withdrawals and commitment takedowns are imperfectly correlated, the two activities can share the costs of the liquid‐asset stockpile. We develop this idea with a simple model, and use a variety of data to test the model empirically.
