Our data show that nearly all firms borrow for the first time in their life from a single bank, but soon afterward some of them start borrowing from additional banks. Duration analysis shows that the likelihood of a firm substituting a single relationship with multiple relationships increases with the duration of that relationship. It also shows that this substitution is more likely to occur for firms with more growth opportunities and for firms with poor performance. The analysis of the ex post effects of the initiation of multiple relationships, in turn, shows that firms with higher levels of investment prior to the initiation of multiple relationships increase their investment even further when they start to borrow from multiple banks and that firms with poor prior performance continue to perform poorly afterward. These results suggest that concerns with hold-up costs, together with an unwillingness by the incumbent bank to increase its exposure to a firm because of its past poor performance, are the key reasons for these firms to initiate an additional relationship this early in their life.

We use a simulation model for a pharmaceutical R&D program to examine the tradeoff between objectivity and relevance of accounting information under various methods of R&D reporting. A simple capitalization rule, similar to the successful‐efforts method of capitalizing oil and gas exploration costs, provides a stronger relation between accounting information and economic values than immediate expensing of R&D outlays or capitalizing the full cost of outlays. The superior relevance of this “successful‐efforts” method persists even when earnings management is widespread.

This study presents a general approach for selecting comparable firms in market‐based research and equity valuation. Guided by valuation theory, we develop a “warranted multiple” for each firm, and identify peer firms as those having the closest warranted multiple. We test this approach by examining the efficacy of the selected comparable firms in predicting future (one‐ to three‐year‐ahead) enterprise‐value‐to‐sales and price‐to‐book ratios. Our tests encompass the general universe of stocks as well as a sub‐population of so‐called “new economy” stocks. We conclude that comparable firms selected in this manner offer sharp improvements over comparable firms selected on the basis of other techniques.

With a year of equity loans by a major lender, we measure the effect of actual short-selling costs and constraints on trading strategies that involve short-selling. We find the loans of initial public offering (IPOs), DotCom, large-cap, growth and low-momentum stocks to be cheap relative to the strategies’ documented profits and that investors who can short only stocks that are cheap and easy to borrow can enjoy at least some of the profits of unconstrained investors. Most IPOs are loaned on their first settlement days and throughout their first months, and the underperformance around lockup expiration is significant even for the IPOs that are cheap and easy to borrow. The effect of short-selling frictions appears strongest in merger arbitrage. Acquirers’ stock is expensive to borrow, especially when the acquirer is small, though the major influence on trading profits is not through expense but availability.

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.

This study theoretically and empirically examines altruistic and joy-of-giving motivations underlying contributions to charitable activities. The theoretical analysis shows that in an economy with an infinitely large number of donors, impurely altruistic preferences lead to either asymptotically zero or complete crowd-out. The paper then establishes conditions on preferences that are sufficient to yield zero crowd-out in the limit. These conditions are fairly weak and quite plausible. An empirical representation of the model is estimated using a new 198692 panel of donations and government funding from the United States to 125 international relief and development organizations. Besides directly linking sources of public and private support, the econometric analysis controls for unobserved institution-specific factors, institution-specific changes in leadership, year-to-year changes in need, and expenditures by related organizations. The estimates show little evidence of crowd-out from either direct public or related private sources. Thus, at the margin, donations to these organizations appear to be motivated solely by joy-of-giving preferences. In addition to addressing the basic question of motives behind charitable giving, the results help explain the existing disparity between econometric and experimental crowd-out estimates.
