Changes in Cash: Persistence and Pricing Implications

Journal of Accounting Research 2014 52(3), 599-634
ABSTRACT This paper decomposes the cash component of earnings and analyzes persistence characteristics and pricing implications of various subcomponents, with particular attention to changes in cash. Changes in underlying fundamentals might dictate changes in cash to new optimal levels. Alternatively, suboptimal changes in cash might result from agency costs allowing managers’ actions to diverge from the best interests of shareholders. We predict and find that both suboptimal increases and decreases in cash bode poorly for future earnings. In fact, we find that suboptimal increases (decreases) in cash have less (greater) persistence than any of the earnings components we study, including accruals and net distributions to both shareholders and debt holders. Market efficiency tests indicate that the market severely punishes firms with suboptimal decreases in cash, but we find no evidence to support the hubris hypothesis that the market overreacts to the earnings implications of unwarranted increases in cash.

Innovation and financial liberalization

Journal of Banking & Finance 2014 47, 214-229
This paper attempts to shed some light on the role of financial sector policies in generating new knowledge, drawing on the experience of one of the fastest growing and largest developing countries. Using time series data for India over the period 1963–2005, the results indicate that interest rate restraints help generate ideas. Other financial repressionist policies, in the form of high reserve and liquidity requirements, as well as significant directed credit controls, appear to have a dampening effect on ideas production. These results lend some support to the argument that some form of financial sector reforms may help stimulate economic growth via increasing technological innovation.

Modeling and monitoring risk acceptability in markets: The case of the credit default swap market

Journal of Banking & Finance 2014 47, 63-73
Minimal discounted distorted expectations across a range of stress levels are employed to model risk acceptability in markets. Interactions between discounting and stress levels used in measure changes are accommodated by lowering discount rates for the higher stress levels. Acceptability parameters represent a maximal and minimal discount rate, a maximal stress level and the speed of rate reduction in response to stress. An explicit model relating credit default swap (CDS) prices to default probabilities is formulated with a view to making the default risk market acceptable. Data on CDS prices and default probabilities for the six major US banks obtained from the Risk Management Institute of the National University of Singapore is employed to estimate parameters defining acceptability and the movements in market implied recovery rates. We observe that the financial crisis saw an increase in the maximal discount rate and its spread over the minimal rate along with an increase in the maximal stress level being demanded for acceptability and a stable pattern for the speed of rate adjustment through the period. The maximal rate, rate spread and stress levels have come down but with periods in the interim where they have peaked as they did in the crisis. Recovery rates have oscillated and they did fall substantially but have recovered towards 40 percent near the end of the period.

Taxation of Human Capital and Wage Inequality: A Cross-Country Analysis

Review of Economic Studies 2014 81(2), 818-850
Wage inequality has been significantly higher in the U.S. than in continental European countries (CEU) since the 1970s. Moreover, this inequality gap has further widened during this period as the U.S. has experienced a large increase in wage inequality, whereas the CEU has seen only modest changes. This article studies the role of labour income tax policies for understanding these facts, focusing on male workers. We construct a life cycle model in which individuals decide each period whether to go to school, work, or stay non-employed. Individuals can accumulate human capital either in school or while working. Wage inequality arises from differences across individuals in their ability to learn new skills as well as from idiosyncratic shocks. Progressive taxation compresses the (after-tax) wage structure, thereby distorting the incentives to accumulate human capital, in turn reducing the cross-sectional dispersion of (before-tax) wages. Consistent with the model, we empirically document that countries with more progressive labour income tax schedules have (i) significantly lower before-tax wage inequality at different points in time and (ii) experienced a smaller rise in wage inequality since the early 1980s. We then study the calibrated model and find that these policies can account for half of the difference between the U.S. and the CEU in overall wage inequality and 84% of the difference in inequality at the upper end (log 90–50 differential). In a two-country comparison between the U.S. and Germany, the combination of skill-biased technical change and changing progressivity of tax schedules explains all the difference between the evolution of inequality in these two countries since the early 1980s.

Human Capital and the World Technology Frontier

The Review of Economics and Statistics 2014 96(4), 676-692
This paper examines the productivity growth effects of educational attainment and its interaction with the distance to the world technology frontier, which is the percentage distance to the country with the highest total factor productivity (TFP) (the United Kingdom or United States), while allowing for the endogeneity of educational attainment in some of the estimates. For this purpose, a new annual data set for educational attainment is constructed for 21 industrialized countries over the period from 1870 to 2009. The results show that changes in educational attainment and the interaction between education and the distance to the frontier, as predicted by Schumpeterian growth theory, have been influential for productivity growth over the past 140 years.

The Swaption Cube

Review of Financial Studies 2014 27(8), 2307-2353 open access
We infer conditional swap rate moments model independently from swaption cubes. Conditional volatility and skewness exhibit systematic variation across swap maturities and option expiries (conditional kurtosis less so), with conditional skewness sometimes changing sign. Conditional skewness displays some relation to the level and volatility of swap rates but is most consistently related to the conditional correlation between swap rates and swap rate variances. From realized excess returns on synthetic variance and skewness swap contracts, we infer that variance and (to a lesser extent) skewness risk premia are negative and time varying. For the most part, results hold true in both the USD and EUR markets and in both precrisis and crisis subsamples. We design and estimate a dynamic term structure model that captures much of the dynamics of conditional swap rate moments.

Can firms learn by observing? Evidence from cross-border M&As

Journal of Corporate Finance 2014 25, 202-215
In the presence of high uncertainty and limited experience, can observing the actions of other acquiring predecessors help firms make better acquisition decisions? Using a sample of cross-border M&As conducted by US acquirers in developing countries, we document a positive and significant relationship between an acquirer's performance and its predecessors' acquisition activity. This relationship is especially pronounced in the prevalence of news events about the outcome of predecessors' acquisitions, when predecessors consist of US peers from the same industry and/or when targets are based in culturally distant countries. Our findings shed light on one channel through which information spillovers across industries and acquiring firms could be a key driver of value creation in developing market cross-border M&As.

On Confidence Intervals for Autoregressive Roots and Predictive Regression

Econometrica 2014 82(3), 1177-1195
Local to unity limit theory is used in applications to construct confidence intervals (CIs) for autoregressive roots through inversion of a unit root test (Stock (1991)). Such CIs are asymptotically valid when the true model has an autoregressive root that is local to unity (ρ = 1 + c/n), but are shown here to be invalid at the limits of the domain of definition of the localizing coefficient c because of a failure in tightness and the escape of probability mass. Failure at the boundary implies that these CIs have zero asymptotic coverage probability in the stationary case and vicinities of unity that are wider than O(n−1/3). The inversion methods of Hansen (1999) and Mikusheva (2007) are asymptotically valid in such cases. Implications of these results for predictive regression tests are explored. When the predictive regressor is stationary, the popular Campbell and Yogo (2006) CIs for the regression coefficient have zero coverage probability asymptotically, and their predictive test statistic Q erroneously indicates predictability with probability approaching unity when the null of no predictability holds. These results have obvious cautionary implications for the use of the procedures in empirical practice.
