Much of the applied work in finance, for instance the literature on capital budgeting, assumes that a firm's management has an accurate estimate of the firm's beta. This estimate is presumably derived by running a regression of the form:

where:

Ri = rate of return on equity for firm i,

Rf = the risk-free rate, and

u = a white noise random variable.

Using a data set of Korean business groups in the period 1999–2006, just after the Asian Financial Crisis, this study shows how business groups’ financial leverage can lead group-affiliated firms to lose market share to industry rivals. This analysis reveals that the negative effect of group leverage is greater when an affiliated firm is financially weak. Additionally, high group leverage is more detrimental to firms operating in fast-growing industries, discouraging affiliated firms from investing while encouraging their rivals. The results suggest that groups’ financial positions encompass a substantial strategic dimension of group-affiliated firms.

We solve for optimal consumption and portfolio choice in a life-cycle model with short-sales and borrowing constraints; undiversifiable labor income risk; and a predictable, time-varying, equity premium and show that the investor pursues aggressive market timing strategies. Importantly, in the presence of stock market predictability, the model suggests that the conventional financial advice of reducing stock market exposure as retirement approaches is correct on average, but ignoring changing market information can lead to substantial welfare losses. Therefore, enhanced target-date funds (ETDFs) that condition on expected equity premia increase welfare relative to target-date funds (TDFs). Out-of-sample analysis supports these conclusions.

We highlight the role of cash-flow uncertainty on corporate employment and investment. We find that a 1% increase in cash-flow uncertainty leads to a 0.62% decrease in tangible investment, a 1.39% decrease in intangible investment, and a 3.67% decrease in corporate employment growth. Our results are statistically and economically significant. We further find that these relationships are stronger during economic recessions. Our findings have significant policy implications. To wit, if policy makers would like corporations to increase their employment and investment, they should focus on policies that decrease corporate cash-flow uncertainty.

Stock split ex-dates are associated with both an increased intensity of small investor buying and a positive abnormal return. The broker promotion hypothesis suggests that the increase in relative spread after a split induces brokers to promote splitting stocks to small investors. The trading inconvenience hypothesis ascribes the ex-split effects to inconveniences such as investors' aversion to dealing with due bills, which is unrelated to relative spreads. The reduction in the bid-ask spread due to decimalization allows us to disentangle these two hypotheses. During the 1/8th pricing period, we show that after the ex-date, the relative spread increases significantly. The average buy order size decreases and the frequency of small transactions increases after the split. After decimalization, these changes are smaller in magnitude. We observe significant positive abnormal returns around the ex-date during the 1/8th pricing period, but not in the decimal pricing period. These results support the broker promotion hypothesis.

This paper provides a new explanation for why closed-end bond funds coexist along with otherwise identical open-end bond funds. Closed-end bond funds offer investors the opportunity to leverage their fixed income investment at very low borrowing rates and are attractive to investors for this reason. We find that differences in leverage are reflected in the discount on closed-end bond funds in a manner consistent with the advantage of leverage.

I investigate whether changes in stock market participation costs can explain the long-term increase in the number of U.S. stockholders. I separate these costs into two components: an information cost (the cost of collecting market information), and an entry cost (all other costs, including commissions and fees), and disentangle their general equilibrium implications in a noisy rational expectations economy. While a falling information cost cannot explain the observed increase in stock market participation, a falling entry cost can account for this plus several other features of the U.S. economy, including the falling equity premium, rising return variances, and the boom in passive relative to active investing.

By integrating staggered interstate banking deregulation into a gravity model following Goetz, Laeven, and Levine (2013), (2016), we construct a time-varying, bank-specific instrument for geographic diversification and investigate its causal effect on corporate innovation via the lending channel. We find that bank geographic diversification spurs corporate innovation and enhances the economic value of innovation. We identify relaxing debt covenants and alleviating borrowers’ financial constraints as the two underlying mechanisms explaining the documented effects. Moreover, by offering lenient covenants, geographically diversified banks provide greater financial and operational flexibility to borrowing firms, enabling them to engage in future mergers and acquisitions.

This paper examines estimation issues associated with multivariate tests of asset pricing. Two issues are considered: (1) the constraint that the sample size (N) must be less than the time series (T), and (2) the relative effect on power of using the multivariate statistic versus a univariate counterpart. We find that an alternative statistic that allows for large N does not dominate the usual portfolio tests. More notably, we find that the power of a simple diagonal statistic usually dominates the multivariate statistic for cases considered in this study.

We develop a dynamic game-theoretic model of a futures market in which prices can be manipulated by corner and squeeze. We investigate equilibrium trading strategies and the price dynamics these strategies produce. Price paths produced by our model can mimic observed prices for potentially comerable commodities and explain the volatility of certain prices even when no manipulations occur. Our model also generates occasional apparent price bubbles and accounts for the existence of normal backwardation in futures markets even when players are risk neutral.

The flattening of yield curves at long-term maturities is proven to be approximately proportional to the reciprocal of the time to maturity under general conditions. This is a consequence of the persistence of earlier forward rates in the averaging process, which produces yields from forward rates. This relationship suggests the use of a “reciprocal maturity yield curve,” which significantly facilitates the interpretation of the behavior of long-term yields by linearizing them for display over a shorter interval. This is illustrated using a yield curve for U.S. Treasury bills.

The literature on leasing has generally concentrated on providing management with a selection criterion for the lease-versus-purchase decision; over the years, a variety of recommendations have been advanced ([1], [3], [6], [8], [16], and [18]). More recent papers, however, have shown that the terms of leasing contracts in a transaction-costless competitive capital market will inevitably be such as to render the stockholders of value-maximizing firms indifferent to that decision ([11] and [12]). Simply put, competition among potential lessors-together with the mandates of securities-price-equilibrating trading activities of investors in lessee and lessor firms—will necessarily drive the present values of the cash flows associated with lease arrangements to parity with direct asset purchase prices.

We study an investor’s asset allocation problem with a recursive utility and with tradable volatility that follows a 2-factor stochastic volatility model. Consistent with previous findings under the additive utility, we show that the investor can benefit substantially from volatility trading due to hedging demand. Unlike existing studies, we find that the impact of elasticity of intertemporal substitution (EIS) on investment decisions is of 1st-order importance. Moreover, the investor can incur significant economic losses due to model and/or parameter misspecifications where the EIS better captures the investor’s attitude toward risk than the risk aversion parameter.

Pricing in the euroyen market is based on LIBOR, the London Interbank Offered Rate, set at 11:00AM London time or TIBOR, the Tokyo Interbank Offered Rate, set at 11:00AM Tokyo time. The changing TIBOR-LIBOR spread reflects the credit risk associated with Japanese banks or the “Japan premium”. The spread is modeled as a function of determinants of bank default and firm value. Systematic variation in the spread can be explained by interest rate and stock price effects along with public information flows of good and bad news regarding Japanese banking, with a separate role for bank credit downgrades and upgrades.

This paper studies the effect of hedge-fund trading on idiosyncratic risk. We hypothesize that while hedge-fund activity would often reduce idiosyncratic risk, high initial levels of idiosyncratic risk might be further amplified due to fund loss limits. Panel-regression analyses provide supporting evidence for this hypothesis. The results are robust to sample selection and are further corroborated by a natural experiment using the Lehman bankruptcy as an exogenous adverse shock to hedge-fund trading. Hedge-fund capital also explains the increased idiosyncratic volatility of high-idiosyncratic-volatility stocks as well as the decreased idiosyncratic volatility of low-idiosyncratic-volatility stocks over the past few decades.

In spite of the growing research concerning investor protection, the relation between investor protection and real investment by foreign multinationals is largely unexplored. Recognizing this relation, however, is especially important in light of the surge in cross-border activity in recent decades and the potential impact cross-border investment can have on a country's economic development. We find that U.S. multinational foreign investment is significantly greater both when shareholder protection is poor and when creditor protection is poor. Consistent with existing literature, our results suggest that U.S. firms have greater comparative advantages when local firms in poor investor protection countries either i) invest suboptimally due to agency problems or ii) have constrained access to debt capital. The increased investment by U.S. multinationals in poor investor protection countries is of particular interest, because it suggests an important way in which adverse outcomes related to poor investor protection may be mitigated.

This paper reexamines the issue of common stock market risk stationarity by applying a newly available exact test for random-walk regression coefficients. For each eight-year subperiod tested in the 1951–1974 interval, betas for individual New York Stock Exchange-listed stocks appeared to be nonstationary. The statistical powers of the exact test and of locally most powerful tests are compared to the power of the test employed previously by Sunder. These power considerations are cited to explain the differences between test results obtained here and those reported by Sunder.

Estimation and control of security risk are subjects of major theoretical and practical importance. Much of the literature in this area has focused on the risk associated with returns over a single holding period. Within this context, a great deal of attention has been devoted to estimation of security betas, which relate to coveriance with “the market,” since the well-known Capital Asset Pricing Model implies that expected returns will, in equilibrium, be related to such values. However, a number of papers [3, 7, 14] have considered “extra-market covariances,” i.e., covariances among security returns not due to common correlations with the market as a whole. Accurate estimates of such covariances are necessary for tailoring portfolios to account for differences in investors' circumstances (e.g., tax brackets) and, a fortiori, for active portfolio management designed to exploit any security mispricing.

We show that the 2016 Brexit Referendum had multifaceted consequences for corporate America, shaping employment, investment, divestitures, R&D, and savings. The unexpected vote outcome led U.S. firms to cut jobs and investment within U.S. borders. Using establishment-level data, we document that these effects were modulated by the reversibility of capital and labor. American-based job destruction was particularly pronounced in industries with less skilled and more unionized workers. U.K.-exposed firms with less redeployable capital and high input-offshoring dependence cut investment the most. Data on the near universe of U.S. establishments also point to measurable, negative effects on establishment turnover (openings and closings). Our results demonstrate how foreign-born political uncertainty is transmitted across international borders, shaping domestic capital formation and labor allocation.

Mergers in Japan have the dubious distinction of not creating wealth for shareholders of target firms, in sharp contrast to what occurs in much of the rest of the world. Using a sample of 91 mergers from 1982 through 2003 we document several distinctive features of the merger market in Japan: Mergers tend to be countercyclical and appear to be driven chiefly by creditor concerns. In particular, where the merging firms share a common main bank, we find that merger gains are lower. Overall, our results point to a market that is distinctly less shareholder focused than that in the U.S., and a market where creditors play an important, perhaps dominant, role in corporate governance.
