Knowledge that Transforms

U.S. multinational firms hold significantly more cash than domestic firms. I study this cash differential using a dynamic model featuring corporate physical and intangible investment, cross-border decisions, and financial policies. I find that the cash differential diminishes by 42% if repatriation costs are set to zero. Hence, costly repatriation induces cash accumulation offshore. Further, firms that invest overseas have different ex ante cash policies from firms that do not. I examine this self-selection effect by eliminating heterogeneous intangibility across multinational and domestic firms, which reduces the cash differential by 28%. I also examine the likelihood of corporate inversion under federal regulations. The estimated annual tax loss to the U.S. Treasury from inversions is reduced from 2.2 billion to 1.3 billion if the requirements for foreign ownership are tightened from 20% to 50%.

Despite the importance of banks’ role as delegated monitors, little is known about how non-price terms of loan contracts are structured to optimize information production in a lending relationship. Using a large sample of corporate loans, this paper examines the effect of relationship lending on covenant choice. Consistent with information asymmetry theories, covenant tightness is relaxed over the duration of a relationship, especially for opaque borrowers. In contrast, the effect of lending relationship intensity on the number of covenants included in a loan follows an inverted U shape. I discuss potential explanations for this finding.

The persistence of returns is a critical issue for investors in their choice of private equity managers. In this paper, we analyse buyout performance persistence in new ways, using a unique database containing cash flow data on 13,523 portfolio company investments by 865 buyout funds. We focus on unique realized deals and find that persistence of fund managers has substantially declined as the private equity sector has matured and become more competitive. Private equity has, therefore, largely conformed to the pattern found in most other asset classes in which past performance is a poor predictor of the future.

We investigate the optimal savings decisions for investors with access to pre-tax (traditional) and post-tax (Roth) versions of tax-advantaged retirement accounts. The model features a progressive tax schedule and uncertainty over future tax rates. Traditional accounts are valuable for hedging retirement account performance and managing current income near tax-bracket cutoffs, whereas Roth accounts allow investors to mitigate uncertainty over future tax schedules. The optimal asset location policy for most households involves diversifying between traditional and Roth vehicles. Contrary to conventional advice, the substantial economic benefits from Roth investments are not limited to investors with low current income.

We develop a dynamic model of banking to assess the effects of liquidity and leverage requirements on banks’ financing decisions and insolvency risk. In this model, banks face taxation, issuance costs of securities, and default costs and maximize shareholder value by choosing their debt-to-asset ratio, deposits-to-debt ratio, liquid asset holdings, equity issuance and default policies in response to these frictions as well as regulatory requirements. Our analytic characterization of the bank policy choices shows that imposing liquidity requirements leads to lower bank losses in default at the cost of an increased likelihood of default. Combining liquidity and leverage requirements reduces both the likelihood of default and the magnitude of bank losses in default.

A model in which homebuyers make a modest approximation leads house prices to display three features present in the data but usually missing from rational models: momentum at one-year horizons, mean reversion at five-year horizons, and excess longer-term volatility relative to fundamentals. Approximating buyers assume that past prices reflect only contemporaneous demand, just like professional economists who use trends in housing prices to infer trends in housing demand. Consistent with survey evidence, this approximation leads buyers to expect increases in the market value of their homes after recent house price increases.

Stock prices incorporate less news before negative events than positive events. Further, informed agents use less price aggressive (limit) orders before negative events and more price aggressive (market) orders before positive events (buy–sell asymmetry). Motivated by these patterns, we model the execution risk that informed agents impose on each other and relate the asymmetry to costly short selling. When investor base is narrow, security borrowing is difficult, or the magnitude of the event is small, buy–sell asymmetry is pronounced and price discovery before negative events is lower. Overall, we show that the strategies of informed traders influence the process of price formation in financial markets, as predicted by theory.

Prior research finds that firms hire directors for their acquisition experience, regardless of acquisition quality (whether their prior acquisitions earned positive or negative announcement returns). Using several short- and long-run measures, we examine the effects of directors’ acquisition experience on the acquisition performance of firms hiring them. We find that board acquisition experience is positively related to subsequent acquisition performance, demonstrating that firms appropriately value experience. Beyond experience itself, however, the quality of directors’ prior acquisitions is also important. Our results suggest that firms may be better served to select directors based upon both past acquisition experience and acquisition performance.

Much research has suggested that independent boards of directors are more effective in reducing agency costs and improving firm governance. How they influence innovation is less clear. Relying on regulatory changes, we show that firms that transition to independent boards focus on more crowded and familiar areas of technology. They patent and claim more and receive more total future citations to their patents. However, the citation increase comes mainly from incremental patents in the middle of the citation distribution; the numbers of uncited and highly cited patents—arguably associated with riskier innovation strategies—do not change significantly.

We examine the effects of high-frequency traders (HFTs) on liquidity using the September 2008 short sale-ban. To disentangle the separate impacts of short selling by HFTs and non-HFTs, we use an instrumental variables approach exploiting differences in the ban's cross-sectional impact on HFTs and non-HFTs. Non-HFTs’ short selling improves liquidity, as measured by bid-ask spreads. HFTs’ short selling has the opposite effect by adversely selecting limit orders, which can decrease liquidity supplier competition and reduce trading by non-HFTs. The results highlight that some HFTs’ activities are harmful to liquidity during the extremely volatile short-sale ban period.
