The Happiness Trade‐Off between Unemployment and Inflation

Unemployment and inflation lower well‐being. The macroeconomist Arthur Okun characterized the negative effects of unemployment and inflation by the misery index—the sum of the unemployment and inflation rates. This paper makes use of a large European data set, covering the period 1975–2013, to estimate happiness equations in which an individual subjective measure of life satisfaction is regressed against unemployment and inflation rate (controlling for personal characteristics, country, and year fixed effects). We find, conventionally, that both higher unemployment and higher inflation lower well‐being. We also discover that unemployment depresses well‐being more than inflation. We characterize this well‐being trade‐off between unemployment and inflation using what we describe as the misery ratio. Our estimates with European data imply that a 1 percentage point increase in the unemployment rate lowers well‐being by more than five times as much as a 1 percentage point increase in the inflation rate.     

Systemic Liquidation Risk and the Diversity–Diversification Trade‐Off

This paper proposes a portfolio choice model in which investors are subject to liquidation risk and (endogenously) face higher costs in the event of joint liquidation (as was observed during the crisis of 2008 to 2009). The risk of joint liquidation creates an incentive for investors to choose heterogeneous portfolios and to rationally forgo diversification benefits. Joint liquidation risk is also reflected in asset prices, resulting in (1) assets with high idiosyncratic risk having low expected returns, and (2) assets that display high correlation with the portfolios of (liquidation‐prone) investors having high expected returns.     

Nonlinearity and Flight‐to‐Safety in the Risk‐Return Trade‐Off for Stocks and Bonds

We document a highly significant, strongly nonlinear dependence of stock and bond returns on past equity market volatility as measured by the VIX. We propose a new estimator for the shape of the nonlinear forecasting relationship that exploits variation in the cross‐section of returns. The nonlinearities are mirror images for stocks and bonds, revealing flight‐to‐safety: expected returns increase for stocks when volatility increases from moderate to high levels while they decline for Treasuries. These findings provide support for dynamic asset pricing theories in which the price of risk is a nonlinear function of market volatility.     

What Makes the Output–Inflation Trade‐Off Change? The Absence of Accelerating Deflation in Japan

It is standard to model the output–inflation trade-off as a linear relationship with a time-invariant slope. We assess empirical evidence for two sets of theories that allow for endogenous variation in the slope of the short-run Phillips curve. At an empirical level, we examine why large negative output gaps in Japan in the late 1990s did not lead to accelerating deflation but instead coincided with stable, albeit moderately negative inflation. Our results suggest that this episode is most convincingly interpreted as reflecting a gradual flattening of the Phillips curve. We find that this flattening is best explained by models with endogenous price durations. These models imply that in any economy where trend inflation is substantially lower (or substantially higher) today than in past decades, time variation in the slope of the Phillips curve has become too important to ignore.     

Time‐Varying Risk–Return Trade‐off in the Stock Market

We uncover a strong comovement of the stock market risk–return trade‐off with the consumption–wealth ratio (CAY). The finding reflects time‐varying investment opportunities rather than countercyclical aggregate relative risk aversion. Specifically, the partial risk–return trade‐off is positive and constant when we control for CAY as a proxy for investment opportunities. Moreover, conditional market variance scaled by CAY is negatively priced in the cross‐section of stock returns. Our results are consistent with a limited stock market participation model, in which shareholders require an illiquidity premium that increases with CAY, in addition to the risk premium that is proportional to conditional market variance.     

A Gap‐Filling Theory of Corporate Debt Maturity Choice

We argue that time variation in the maturity of corporate debt arises because firms behave as macro liquidity providers, absorbing the supply shocks associated with changes in the maturity structure of government debt. We document that when the government funds itself with more short‐term debt, firms fill the resulting gap by issuing more long‐term debt, and vice versa. This type of liquidity provision is undertaken more aggressively: (1) when the ratio of government debt to total debt is higher and (2) by firms with stronger balance sheets. Our theory sheds new light on market timing phenomena in corporate finance more generally.     

Ex‐Dividend Profitability and Institutional Trading Skill

We use institutional trading data to examine whether skilled institutions exploit positive abnormal ex‐dividend returns. Results show that institutions concentrate trading around certain ex‐dates, and earn higher profits around these events. Dividend capture trades represent 6% of all institutional buy trades but contribute 15% of overall abnormal returns. Institutional dividend capture trading is persistent. Institutional ex‐day profitability is also strongly cross‐sectionally related to trade execution skill. The relation between execution skill and profits disappears around placebo non‐ex‐days. Results suggest that skilled institutions target certain opportunities rather than benefiting uniformly over time. Furthermore, only skilled institutions can profit from dividend capture.     

Profitability and investment‐based factor pricing models

Ex ante predictors of stock returns must exhibit explanatory power across the feasible set of investments. But empirical results of factor pricing models that incorporate firm investment and profitability cannot explain the apparently high returns of US small stocks with very high investment levels and very low profitability. Whilst these stocks comprise only a small fraction of US data sets, this is not the case across global markets. Using a data set that is concentrated with stocks that exhibit high investment despite low profitability, we demonstrate that such factor models are limited in their explanatory power over these stocks.     

Mean Reversion in Profitability for Non‐listed Firms

The presence of mean reversion in profitability at the firm level is important for valuation and prediction of growth and earnings. We investigate the mean reversion in accounting profitability for Norwegian non‐listed firms for the period 1988–2006. We find a mean reversion rate of about 0.44 per year. This is higher than found in other studies. We also find that small firms have a higher mean reversion rate than large firms. Our results should have important practical implications for the difficult task of valuing non‐listed firms. Previously, price‐to‐book ratios have been used to investigate changes in profitability over time for listed firms. We examine bankruptcy risk as an alternative variable for unlisted firms. We find that bankruptcy risk may help explain changes in profitability, but the results are not as strong as found in previous work.     

The Optimal Currency Composition of External Debt: Theory and Applications to Mexico and Brazil

The changes in exchange rates, interest rates, and commodityprices during the past decades have had large impacts on developingcountries. Many developing countries have limited access toalready incomplete international long-term hedging markets.Thus the question arises whether the currency composition ofexternal debt can be used to minimize exposure to external pricerisk. Using a utility-maximizing framework, this article showsthat, by choosing the optimal currency composition, a countrycan indeed manage its external exposure. The optimal, risk-minimizingcurrency composition depends on the relation between exportreceipts and the costs of borrowings in each currency and onthe relations among the costs of borrowings in different currencies.A simple methodology can be used to derive the optimal sharesof individual currencies and is applied to Mexico and Brazil.The results show that Mexico and Brazil could have lowered theirexternal exposure to a limited degree by continuously alteringthe currency composition of their debts. The low correlationsbetween the costs of borrowings and export and import pricesmake the currency composition of debt a very imperfect hedgingtool, and it is likely that hedging instruments directly linkedto prices are preferable.     

Taxes and the Theory of Trade Debt

In this paper, we show that taxes motivate the flow of trade credit without involving the assumption of credit market imperfections. The direction of trade credit flow depends on the distribution of marginal tax rates among buyers and sellers. In equilibrium, the trade credit decision follows a tax-induced clientele on both the supply and demand side.     

Claims‐Made and Reported Policies and Insurer Profitability in Medical Malpractice

The liability crisis of the 1970s led to the introduction of a new type of insurance policy designed to reduce the undiversifiable uncertainty associated with writing long‐tail liability lines. These new claims‐made and reported policies gained favor in place of the traditional occurrence coverage in the early 1980s not only in medical malpractice but also in the general liability arena. The main question we want to address in this article is why two types of contracts that cover the same risk exposure exist in the medical malpractice insurance industry whereas only one exists primarily in other insurance lines.     

Short‐Term Corporate Debt around the World

Short‐term corporate debt as a proportion of total debt issued by public firms varies greatly across countries, between 28% in the United States and 78% in China. This paper argues that the interaction between information asymmetry and legal protection of creditors is an important determinant of debt maturity. When short‐term debt plays a dual role as signaling and commitment devices, a reduction in information asymmetry has a larger impact on debt maturity when creditor rights are weaker. We find empirical support for this prediction using firm‐level data from 45 countries around the world.     

Pre‐Issuance Hedging of Fixed‐Rate Debt

This article analyzes several corporate hedging strategies to manage interest rate risk on fixed‐rate debt prior to issuance. The authors start by considering these strategies using a highly stylized model: a binomial forward interest rate tree that, while simple in design, illustrates derivative pricing methodologies that are used in practice. Under a given rate volatility assumption, they demonstrate expected outcomes when entering a forward bond contract, a forward‐starting pay‐fixed interest swap, and a purchased option on that swap, as well as the “default” alternative of doing nothing. In principle, the decision of whether or not to hedge, as well as how to do so, depends on management's view of future interest rate volatility and degree of comfort with possible outcomes. The authors then assess the pros and cons of hedging strategies, with considerable emphasis on practical considerations. For example, while their theoretical model would allow an issuer to “lock” a specific debt issuance, in practice one can hedge only “benchmark” interest rate risk. The authors describe the use of both Treasury locks and forward‐starting swaps to address unexpected benchmark yield changes, and discuss how factors such as the time to issuance affect an issuer's choice of instrument. For instance, Treasury locks are typically used when the time to issuance is relatively short, while interest rate swaps are more common for longer times to issuance. The article also discusses circumstances in which a “do nothing” strategy may be preferable to other alternatives, as well as the disadvantages of issuing in advance. Finally, the authors describe the impact of financial accounting on different hedge strategies.     

Should Intangibles Be Measured: What Are the Economic Trade‐Offs?

We investigate whether a firm's intangible investments should be measured and separated from operating expenses. We find that the information extracted from accounting reports of investments and earnings is different when intangibles are measured and identified separately from operating expenses than when intangibles are left commingled with operating expenses. This difference in the market's information causes a change in the behavior of market prices, inducing changes in the firm's investments and cash flows. Thus, from a real effects perspective, measuring intangibles is not unambiguously desirable. We identify the conditions under which providing information on intangibles may be desirable. This study also shows the inadequacy of statistical associations between accounting numbers and prices as a basis for evaluating the desirability of measuring intangible investments. We show that the measurement of intangibles alters the very distribution of cash flows about which the measurement regime is seeking to provide information.     

Expected versus Ex Post Profitability in the Cross‐Section of Industry Returns

Asset pricing theory predicts a positive cross‐sectional relation between expected profitability and expected returns. However, empirical studies typically use lagged ex post profitability as a proxy for expected profitability. In this article, we use out‐of‐sample combination forecasts to estimate expected industry‐level operating profit, gross profit, operating cash flow, and net income. We then construct real‐time industry‐rotation strategies based on high and low expected profitability. For each measure except gross profit, these predicted‐profitability strategies earn significant alpha net of transaction costs and outperform strategies based on ex post profitability.     

Determinants of the Method of Payment in Asset Sell‐Off Transactions

Using a sample of asset sell‐off transactions from January 1990 to April 2010, we find that the method of payment used in asset sell‐off transactions is associated with several characteristics cited in the acquisitions research that reflect cash constraints of the bidder. Specifically, bidders facing more stringent cash constraints are more likely to use equity when purchasing assets, while sellers subjected to cash constraints prefer cash when selling assets. Second, we find that the variation in method of payment among asset sell‐off transactions also is partially explained by variables representing asymmetric information. Third, we apply our model to an expanded sample that includes non‐U.S. sellers of assets and find that an equity payment is more likely when sellers are based in countries that have relatively high country risk (more government restrictions), weak shareholder rights, and a weak legal system. Thus, it appears that bidders prefer that sellers share in the risk of the transaction under these conditions.
