Earnings volatility in America: Evidence from matched CPS

We offer new evidence on earnings volatility of men and women in the United States over the past four decades by using matched data from the March Current Population Survey. We construct a measure of total volatility that encompasses both permanent and transitory instability, and that admits employment transitions and losses from self employment. We also present a detailed decomposition of earnings volatility to account for changing shares in employment probabilities, conditional variances of continuous workers, and conditional mean variances from employment entry and exit. Our results show that earnings volatility among men increased by 15% from the early 1970s to mid 1980s, while women's volatility fell, and each stabilized thereafter. However, this pooled series masks important heterogeneity in volatility levels and trends across education groups and marital status. We find that men's earnings volatility is increasingly accounted for by employment transitions, especially exits, while the share of women's volatility accounted for by continuous workers rose, each of which highlights the importance of allowing for periods of non-work in volatility studies.     

Inequality and Crime: Separating the Effects of Permanent and Transitory Income*

Earlier studies on income inequality and crime have typically used total income or total earnings. However, it is quite likely that it is the changes in permanent rather than in transitory income that affects crime rates. The purpose of this paper is therefore to disentangle the two effects by, first, estimating region‐specific inequality in permanent and transitory income and, second, estimating crime equations with the two separate income components as explanatory variables. The results indicate that it is important to separate the two effects; while an increase in the inequality in permanent income yields a positive and significant effect on total crimes and three different property crimes, an increase in the inequality in transitory income has no significant effect. Using a traditional, aggregate, measure of income yields insignificant effects on crime.     

Lifecycle bias in estimates of intergenerational earnings persistence

This paper identifies a significant negative relationship between estimated intergenerational earnings persistence and the age at which fathers are observed. In total, the estimation methodology and the age of the father at observation account for 40 percent of the variation among existing studies. The paper explores two possible causes of this pattern: increasing attenuation bias resulting from growing transitory earnings variance and a lifecycle bias which follows from the rise in permanent earnings variance over the lifecycle. Evidence presented favors the latter explanation over the former. The paper also considers both formal and informal approaches to mitigating the lifecycle bias.     

The Effects of Household Income Volatility on Divorce

We extend the literature on the effects of earnings shocks on divorce by identifying separately the effects of transitory and permanent household income shocks and by allowing the shocks to have asymmetric effects across education and racial groups. The econometric evidence suggests negative (positive) transitory household income shocks increase (decrease) the probability of divorce, while there is only weak evidence that positive (negative) permanent household income shocks raise (lower) the probability of divorce. Some differences in the effects of household income shocks on divorce propensities arise for subsamples selected by education and race.     

Neighborhood social networks and female self-employment earnings in Taiwan

Using the sample of Taiwanese female self-employed workers from the Taiwan Women and Family Survey (TWFS) conducted in 1989, this article explores neighborhood social networks and female self-employment earnings. The evidence from linear regression and endogenous treatment effect models suggests that an individual’s past provision of personalized assistance to adjacent neighbors significantly increases current self-employment earnings, with corrections for self-selection into network participation. An individual’s past voluntary contributions to community organizational activities also significantly increase current earnings, both with and without corrections for self-selection. However, there are negative self-selections into both cooperative neighborhood networks and community organizational activities in the sense that female self-employed workers with high earnings capacity are less likely to choose to participate in these types of social networks.     

Life-cycle variations in the association between current and lifetime earnings: Evidence for German natives and guest workers

In many economic models a central variable of interest is lifetime or permanent income which is not observed in survey data sets and typically proxied by annual income information. To assess the quality of such approximations, we use a unique source of lifetime earnings — the German pension system — and focus on two important issues that have been largely ignored in the existing literature. The first is how to deal with zero income observations in the analysis of women. The second is whether these approximations differ between natives and guest workers. For female earners, we find that estimates of the associations between current and lifetime income are highly sensitive to the treatment of zero earnings. The reason turns out to be the highly cyclical nature of the labor supply behavior of mothers. Furthermore, immigrants' income proxies are prone to significantly larger attenuation biases over the entire life-cycle. This result is explained by the larger share of annual income variance attributable to the transitory income component for immigrants. Averaging income over up to 15 years alleviates the attenuation bias as well as the difference in biases between natives and guest workers.     

Testing neoclassical convergence in regional incomes and earnings

The time-series properties of per capita income and per capita earnings in the regions of the United States are tested for consistency with the neoclassical growth model's prediction of convergence. We find evidence for per capita income convergence for U.S. regions during the 1929–1990 period after allowing for a trend break in 1946. These findings support the neoclassical model's prediction of convergence. The evidence for per capita earnings convergence is, however, less conclusive. Shocks to per capita earnings are found to be more persistent than shocks to per capita income. This implies that the regional distribution of transfer payments tends to smooth the effects of deviation on relative regional per capita earnings and reinforce trends in per capita income convergence.     

Analysts' utilization of historical earnings information

This study examines whether security analysts (in)efficiently utilize the information contained in past series of annual and quarterly earnings in producing earnings forecasts. To do so, it investigates whether equal-weighted combinations of security analysts' forecasts with forecasts from statistical models based on historical earnings are superior, both in terms of being a better surrogate for the market's expectations of earnings and of accuracy, to forecasts from either one of these two sources. The empirical findings indicate that, although analysts' forecasts are superior to forecasts from statistical models, performance can be improved—both in terms of accuracy and also of being a better surrogate for market earnings expectations—by combining analysts' forecasts with forecasts from statistical models based on past quarterly earnings. Improvements in proxying for market earnings expectations were obtained even when analysts' forecasts made in June of the forecast year were used in the combinations. An implication of these findings is that investors can improve their investment decisions by using an average of the mean analysts' forecasts and the forecast produced by a time-series model of quarterly earnings in their investment decisions.     

How CEO narcissism affects earnings management behaviors

This study examined whether chief executive officers’ (CEOs) with narcissistic tendencies are more likely to execute earnings management behavior because of pressure to fulfill earnings thresholds. The results revealed that a CEO who exhibits high narcissism is more likely to be involved in earnings management to compensate for her/his performance. Our findings suggest that CEO narcissism directly influences financial decisions. Considering the earnings thresholds, firms with a more narcissistic CEO experience a regulatory effect on real earnings management behavior. Studies have indicated that CEOs manipulate earnings to satisfy three primary earnings thresholds: prior year’s reported earnings, zero earnings, and analysts’ forecasts. Our empirical results provide further evidence that CEOs engage in earnings management to fulfill positive earnings thresholds and analysts’ forecasts. We infer that CEOs use the abnormal production cost method as an underlying mechanism to increase reported earnings. Our findings help clarify the relationship between CEO personality traits and earnings manipulation to assist investors with decision-making.     

The contractual and value relevance of reported earnings in a dividend-focused environment

This study investigates the relevance of reported earnings in the context of an institutional environment, i.e., Switzerland, in which investors focus on dividends. In conjunction with a dividend focus, the financial reporting environment faced by Swiss firms provides their managers with more accounting discretion than managers of Anglo-Saxon firms typically have. From a contractual perspective, dividendbased earnings management is expected since Swiss corporate law explicitly states that dividends, which must be voted on by stockholders, are to be based upon a firm's reported earnings. From a value perspective, thin trading conditions and a long-term investment horizon are expected to increase the importance of dividend payments and to influence the informativeness of reported earnings. Results indicate that Swiss managers do engage in dividend-based earnings management, that earnings quality signals are used by managers to voluntarily constrain their accounting choices and that the value relevance of earnings is conditional upon dividend payments.     

Literacy and earnings: an investigation of the interaction of cognitive and unobserved skills in earnings generation

This paper uses direct measures of literacy to examine the influence of cognitive and unobserved skills on earnings. We find that cognitive skills contribute significantly to earnings and that their inclusion in earnings equations reduces the measured impact of schooling. The impact of literacy on earnings does not vary across quantiles of the earnings distribution, schooling and literacy do not interact in influencing earnings, and introducing literacy has little effect on the estimated impact of experience. Our findings suggest that cognitive and unobserved skills are both productive but that having more of one skill does not enhance the other's productivity.     

Intergenerational Earnings Mobility Among Daughters and Sons: Evidence from Sweden and a Comparison with the United States

This article adopts Chadwick and Solon's (2002 ) model by using family earnings in the study of intergenerational earnings mobility with a highlight on the role of assortative mating. I analyze mean and quantile regression coefficients as well as transition matrices to investigate family earnings mobility between parents and daughters and parents and sons from Swedish register data. My findings indicate that Sweden has a higher degree of mobility compared to the United States, and that assortative mating also plays an important role as a channel through which income status is transmitted across generations in Sweden. However, the difference in intergenerational mobility patterns between the two countries does not, inherently, depend on factors that affect the marriage match. Swedish daughters and sons exhibit a rather similar scheme of intergenerational earnings transmission. Daughters tend to be slightly more mobile than sons, and the difference between their elasticity estimates is small but statistically significant. The quantile regression approach reveals that parents' family earnings are less important as an explanatory variable at the upper end of the children's earnings distribution than they are at the bottom, while transition matrices show substantial earnings persistence in the top earnings class.     

Women and poverty: Beyond earnings and welfare

Women’s poverty rates are higher than men’s, with single mothers having extremely high poverty rates. This article first briefly examines poverty measures and U.S. poverty rates among men and women. The author then describes and evaluates three categories of economic research on poverty: the lack or inadequacy of employment and earnings; family structure and welfare; and earnings capacities, care-giving responsibilities and employment. Finally the author assesses the policies to alleviate women’s poverty derived from these explanations.     

Stochastic trends and economic fluctuations in a small open economy

In this paper we describe how restricted vector autoregressions can be employed to examine the sources of macroeconomic fluctuations. We show how cointegration restrictions can be used to identify a VAR system with common stochastic trends subject to transitory and permanent changes in average growth, and how we may investigate the system's responses to permanent shocks, i.e. to innovations to the trends. Theoretical cointegration vectors are derived from a small open economy growth model for terms of trade, real GDP, real consumption, and real investments. Applying these methods to Swedish annual data (1875–1986) we find that permanent real (supply) shocks account for most of the fluctuations in GDP, even in the short run.     

An economic analysis of the earnings of industrial accountants

This paper explores hypothesized determinants of accountants' earnings using a conventional Mincer earnings function. Findings indicate that the CPA credential, MBA degree, and years of work experience increase earnings. Also presented is a more detailed analysis of the earnings gap between accountants employed in traditional accounting positions and those in finance-related positions.     

The relationship between accounting numbers and returns: some empirical evidence from the emerging market of the Czech Republic

Generally, stock prices reflect future expectations of earnings, whereas accounting data reflect past performance. This paper attempts to discover the relationship between accounting data and market price returns of the companies listed on the Prague Stock Exchange (PSE). The Prague Stock Exchange was established in 1993 and provides an opportunity to make a comparison between a newly established market and the findings of studies of established markets. There has been a wealth of publications and accounting research studies on developed markets. Generally, accounting attributes are thought to be relevant because they tend to be contemporaneously statistically associated with stock prices. Some studies have suggested, and empirically tested, that stock prices lead earnings (e.g. Collins et al., 1987; Kothari, 1992; Kothari and Sloan, 1992; Kothari and Zimmerman, 1995). This study tests the existence of such a relationship in the Czech capital market, relying partially on the methodology proposed by Kothari and Sloan (1992) and Kothari (1992). This paper investigates whether there is a statistically significant permanent relationship between returns and accounting data on the Czech market. The study was conducted using accounting earnings and stock prices during the period 1993–8. The empirical evidence here suggests that a similar relation exists on the emerging Czech market. The relation is statistically significant for measurement windows of one year and longer. The increase in the mean response coefficient, reported later in this study, suggests that one-leading-year returns are as important as contemporaneous returns in terms of their sensitivity to annual earnings changes. However, one cannot infer with a degree of confidence that the Czech capital market views earnings changes to be largely permanent, which would be consistent with the time-series properties of annual earnings.     

Correlated income shocks and excess smoothness of consumption

In the literature, econometricians typically assume that household income is the sum of a random walk permanent component and a transitory component, with uncorrelated permanent and transitory shocks. Using data on realized individual incomes and individual expectations of future incomes from the Survey of Italian Households׳ Income and Wealth, I find that permanent and transitory shocks are negatively correlated. Relaxing the assumption of no correlation between the shocks, I explore the effects of correlated income shocks on the estimated consumption insurance against permanent and transitory shocks, and consumption smoothness using a life-cycle model with self-insurance calibrated to U.S. data. Negatively correlated income shocks result in smoother consumption, and upward-biased estimates of the insurance against transitory (and permanent when borrowing constraints are not tight) income shocks. While the life-cycle model with negatively correlated shocks fits well the sensitivity of consumption to current income shocks observed in U.S. data, it falls short of explaining the sensitivity of consumption to income shocks cumulated over a longer horizon.     

Estimating the intergenerational persistence of lifetime earnings with life course matching: Evidence from the PSID

Why do estimates of the intergenerational persistence in earnings vary so much for the United States? Recent research suggests that lifecycle bias may be a major factor [Grawe, N., Lifecycle bias in estimates of intergenerational earnings persistence. Labour Economics 2006, 13:551–570; Haider, S., and Solon, G., Life-cycle variation in the association between current and lifetime earnings. American Economic Review 2006, 96(4):1308–1320.]. In this paper we estimate the intergenerational correlation in lifetime earnings by using sons' and fathers' earnings at similar ages in order to account for lifecycle bias. Our estimate based on earnings measured at 35–44 for both fathers and sons is similar to that for the age range 45–54.     

Immigrant earnings,relative to what? The importance of earnings function specification and comparison points

Immigrant relative earnings estimates are sensitive to the choice of comparison point and the specification of earnings. Non-sample mean comparisons (Borjas, 1985) understate relative earnings. Simple earnings specifications (linear education, quadratic experience) overstate relative earnings for both poorly and well-educated immigrants. Specifications which ignore omitted variables understate the relative earnings of poorly educated immigrants and overstate those of well-educated ones. Although measures of assimilation and changes in immigrant quality are insensitive to earnings specification, they indicate strong earnings growth for post-1964 immigrants, an overall decrease in immigrant quality, and an increase in Mexican immigrant quality.     

The relationship between the Beveridge–Nelson decomposition and other permanent–transitory decompositions that are popular in economics

The Beveridge–Nelson (BN) decomposition is a model-based method for decomposing time series into permanent and transitory components. When constructed from an ARIMA model, it is closely related to decompositions based on unobserved components (UC) models with random walk trends and covariance stationary cycles. The decomposition when extended to I(2)$I\left(2\right)$ models can also be related to non-model-based signal extraction filters such as the HP filter. We show that the BN decomposition provides information on the correlation between the permanent and transitory shocks in a certain class of UC models. The correlation between components is known to determine the smoothed estimates of components from UC models. The BN decomposition can also be used to evaluate the efficacy of alternative methods. We also demonstrate, contrary to popular belief, that the BN decomposition can produce smooth cycles if the reduced form forecasting model is appropriately specified.
