盈余管理、金融市场化与公司超额银行借款

公司在获取银行信贷的过程中会通过盈余管理以满足会计业绩审核要求的行为已得到学者们的关注, 但现有文献尚未研究公司在获得一定的银行借款后是否会继续进行盈余管理以获得超额银行借款.本文基于该问题, 以2003年～2016年中国A股上市公司为研究对象, 从应计盈余管理和真实盈余管理两个维度, 考察了盈余管理行为与公司超额银行借款之间的关系.研究结果表明, 应计盈余管理和真实盈余管理均与公司超额银行借款正相关;进一步, 在考虑地区金融市场化程度之后, 发现金融市场化弱化了应计盈余管理与公司超额银行借款的正相关关系, 但增强了公司通过真实盈余管理获得更多超额银行借款的行为.本文从公司超额银行借款行为出发, 同时结合金融市场化程度, 拓展了会计信息质量与信贷资源配置的研究视角.     

Inferring Labor Income Risk and Partial Insurance From Economic Choices

This paper uses the information contained in the joint dynamics of individuals' labor earnings and consumption‐choice decisions to quantify both the amount of income risk that individuals face and the extent to which they have access to informal insurance against this risk. We accomplish this task by using indirect inference to estimate a structural consumption–savings model, in which individuals both learn about the nature of their income process and partly insure shocks via informal mechanisms. In this framework, we estimate (i) the degree of partial insurance, (ii) the extent of systematic differences in income growth rates, (iii) the precision with which individuals know their own income growth rates when they begin their working lives, (iv) the persistence of typical labor income shocks, (v) the tightness of borrowing constraints, and (vi) the amount of measurement error in the data. In implementing indirect inference, we find that an auxiliary model that approximates the true structural equations of the model (which are not estimable) works very well, with negligible small sample bias. The main substantive findings are that income shocks are moderately persistent, systematic differences in income growth rates are large, individuals have substantial amounts of information about their income growth rates, and about one‐half of income shocks are smoothed via partial insurance. Putting these findings together, the amount of uninsurable lifetime income risk that individuals perceive is substantially smaller than what is typically assumed in calibrated macroeconomic models with incomplete markets.     

股利政策、盈余持续性与信号显示

本文基于盈余持续性的概念,实证检验了上市公司的股利类型、股利支付率与企业未来盈利能力的关系,并进一步考察了大股东派发现金股利对盈余持续性的影响.本文的研究发现,总体而言,我国上市公司中派发了现金股利的公司其盈余持续性要强于未派发股利的公司,而且在净利润和营业利润上也表现出更强的增长能力.但在派发现金股利的公司中.股利支付率的大小与盈余持续性强弱并不成简单的线性关系,股利支付率高的公司在盈余的整体及其组成部分上并未表现出更强的盈余持续性.最后,大股东对于现金股利的偏好并未显著影响到盈余的持续性.由此,本文认为,我国上市公司的现金股利政策能够成为以持续性衡量的盈余质量或未来盈利能力的附加信号.     

THE IMPACT OF INCOME SHOCKS ON HEALTH: EVIDENCE FROM COHORT DATA

We study the effect of permanent income innovations on health for a prime‐aged population. Using information on more than half a million individuals sampled over a 25‐year period in three different cross‐sectional surveys we aggregate data by date‐of‐birth cohort to construct a “synthetic cohort” data set with details of income, expenditure, socio‐demographic factors, health outcomes, and selected risk factors. We then exploit structural and arguably exogenous changes in cohort incomes over the 1980s and 1990s to uncover causal effects of permanent income shocks on health. We find that such income innovations have little effect on a wide range of health measures, but do lead to increases in mortality and risky health behaviour. (JEL: I10, D31)     

Approximations for Estimating Change in Life Expectancy Attributable to Air Pollution in Relation to Multiple Causes of Death Using a Cause Modified Life Table

There is considerable debate as to the most appropriate metric for characterizing the mortality impacts of air pollution. Life expectancy has been advocated as an informative measure. Although the life‐table calculus is relatively straightforward, it becomes increasingly cumbersome when repeated over large numbers of geographic areas and for multiple causes of death. Two simplifying assumptions were evaluated: linearity of the relation between excess rate ratio and change in life expectancy, and additivity of cause‐specific life‐table calculations. We employed excess rate ratios linking PM_2.5 and mortality from cerebrovascular disease, chronic obstructive pulmonary disease, ischemic heart disease, and lung cancer derived from a meta‐analysis of worldwide cohort studies. As a sensitivity analysis, we employed an integrated exposure response function based on the observed risk of PM_2.5 over a wide range of concentrations from ambient exposure, indoor exposure, second‐hand smoke, and personal smoking. Impacts were estimated in relation to a change in PM_2.5 from 19.5 μg/m³ estimated for Toronto to an estimated natural background concentration of 1.8 μg/m³. Estimated changes in life expectancy varied linearly with excess rate ratios, but at higher values the relationship was more accurately represented as a nonlinear function. Changes in life expectancy attributed to specific causes of death were additive with maximum error of 10%. Results were sensitive to assumptions about the air pollution concentration below which effects on mortality were not quantified. We have demonstrated valid approximations comprising expression of change in life expectancy as a function of excess mortality and summation across multiple causes of death.     

Empowering leadership and managers' career perceptions: Examining effects at both the individual and the team level

In a multilevel model of leadership behavior, we investigated whether and how empowering leadership affects individuals' career perceptions. We developed a conceptual model that links empowering leadership at the individual level and at the group level (mean as well as dispersion) to individuals' career self-efficacy and career satisfaction. To test our model, we used questionnaire data from a multilevel data set of 2493 employees in leadership positions nested in 704 teams from a large German corporation. Hierarchical linear regression analyses showed that empowering leadership at the individual level was positively related to career self-efficacy, which in turn mediated the relationship between empowering leadership and career satisfaction. Empowering leadership at the group level was positively related to career self-efficacy when it was conceptualized as leadership differentiation (i.e., the standard deviation of empowering leadership ratings), but not when it was conceptualized as leadership climate (i.e., mean empowering leadership ratings). Career self-efficacy in turn mediated the relationship between empowering leadership differentiation and career satisfaction. Finally, we found a negative relationship between empowering leadership differentiation and career satisfaction.     

WHY DO MOST ITALIAN YOUTHS LIVE WITH THEIR PARENTS? INTERGENERATIONAL TRANSFERS AND HOUSEHOLD STRUCTURE

More than 80% of Italian men aged 18–30 live with their parents. We argue that one contributing factor to this remarkably high rate of cohabitation is parents' tastes for coresidence. In order to investigate the role of parental preferences, we estimate the effect of exogenous changes in parental income on rates of cohabitation in Italy using Survey of Households' Income and Wealth (SHIW) micro data from 1989 to 2000. In order to identify a source of exogenous variation in parental income, we use changes in fathers' retirement age induced by the 1992 reform of the Italian Social Security system as an instrumental variable for parental income. By raising retirement age, this reform forced some fathers to remain in the labor market longer than they would have otherwise, therefore raising their disposable income. We use a two‐sample instrumental variable (TSIV) strategy. Our TSIV estimates indicate that a rise in parents' income significantly raises the children's propensity to live at home: A 10% increase in annual parental income results in approximately a 10% rise in the proportion of men living with their parents. Although we cannot definitely rule out alternative interpretations, these results are consistent with our hypothesis that cohabitation is a normal good for Italian parents.

Longevity and Lifetime Labor Supply: Evidence and Implications

Conventional wisdom suggests that increased life expectancy had a key role in causing a rise in investment in human capital. I incorporate the retirement decision into a version of Ben‐Porath's (1967) model and find that a necessary condition for this causal relationship to hold is that increased life expectancy will also increase lifetime labor supply. I then show that this condition does not hold for American men born between 1840 and 1970 and for the American population born between 1890 and 1970. The data suggest similar patterns in Western Europe. I end by discussing the implications of my findings for the debate on the fundamental causes of long‐run growth.     

A Comprehensive Profile of the Working Poor

Abstract. In this paper, a comprehensive profile of the ‘working poor’ is presented using data from the 2003 March Supplement of the Current Population Survey. We test an earnings model with effective cost constraints. The dependent variable is the likelihood of an employed individual being a member of the working poor. The explanatory variables are the worker's occupation and firm characteristics, and cost constraints comprising, on the one hand, the worker's family characteristics (notably family income), and, on the other, the costs to the worker of signals used by firms in making employment decisions. These include not only the cost of education but also what we call ‘discriminatory signals’, e.g. gender, race, ethnicity and citizenship status. The paper provides new insight into the complex set of relationships between the signaling variables themselves, between signals and occupations, and between industries and occupations, in the formation of relative wage rates.     

An Empirical Estimation of the Investor Loss Function Associated with the Use of Analysts' Forecasts of Earnings

The aggregate investor loss function associated with the use of analysts' forecasts of earnings expresses the relation between loss and prediction error. Prior research suggested that the shape of this loss function should provide guidance in decision rules for investors. This study empirically estimates the investor loss function and finds an asymmetry in the relation between loss and analysts' prediction error. For overestimates of earnings, loss is a quadratic function of error; while for underestimates of earnings, loss is a linear function of error.     

Cost of Children,Parental Decisions,and Family Policy

ABSTRACT: The aims and means of family policy are examined in the light of standard economic theory, and of the microeconomics of fertility. It is shown that compensating parents for the cost of having children is unjustified, and that such a cost is not captured by the methods commonly used to estimate it anyway. On the other hand, a family policy may be justified if fertility or parental expenditures on children are‘'too small'’(or‘'too large”) as a result of externalities or market incompleteness; if some couples are physically rationed in their fertility decisions; or in order to relieve poverty. Manipulating taxes on parental earnings and child-specific goods is generally preferable to changing child benefits rates.     

TCDD Exposure-Response Analysis and Risk Assessment

We examined the relation between cancer mortality and time-dependent cumulative exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) estimated from a concentration- and age-dependent kinetic model of elimination, and we estimated incremental cancer risks at age 75. Data from the National Institute for Occupational Safety and Health study of 3,538 workers with occupational exposure to TCDD were analyzed using standardized mortality ratios and Cox regression procedures. Analyses adjusted for potential confounding by age, year of birth, and race and considered exposure lag periods of 0, 10, or 15 years. Other potential confounders including smoking and other occupational exposures were evaluated indirectly. To explore the influence of extreme values of cumulative TCDD ppt-years, we restricted the analysis to observations with exposure below the 95th percentile or used logarithmic (ln) transformed exposure values. We applied penalized smoothing splines to examine variation in the exposure-response relation across the exposure range. TCDD was not statistically significantly associated with cancer mortality using the full data set, regardless of the lag period. When we restricted the analysis to observations with exposure below the 95th percentile, TCDD was associated positively with cancer mortality, particularly when a 15-year lag was applied (untransformed exposure data: regression coefficient , standard error (s.e.) = 1.4 x 10(-6), p < 0.05; ln-transformed exposure data: , s.e. = 2.9 x 10(-2), p < 0.05). The estimated incremental lifetime risk of mortality at age 75 from all cancers was about 6 to more than 10 times lower than previous estimates derived from this cohort using exposure models that did not consider the age and concentration dependence of TCDD elimination.     

Poorer Is Riskier

To examine the relationship between economic well being and health status, two economic concepts were explored: the permanent-income hypothesis and the transitory-income hypothesis. A regression analysis of time-series mortality data for the period of 1950-1988 was conducted. The regression results indicated that the total mortality rate is negatively associated with permanent income and positively associated with the transitory income. Results are also reported for the 8 major causes of death in the United States. The implications for risk analysis are discussed.     

重大公共威胁情境下个体亲社会行为形成机制———以新冠疫情为例

现有研究对于威胁情境和个体亲社会行为的关系并未达成共识.对于两者之间的关系,本研究以新冠肺炎疫情为具体研究情境,从威胁情境的时间和类型两个角度填补了以往研究的空白,以内群体认同和关注他人为中介机制,提出重大公共威胁情境下影响个体捐赠意愿的双路径形成机制和相关调节变量.本文的研究表明,对于新冠疫情这种捐赠方和受助方同时面对的公共威胁情境:1)潜在捐助者所在地的疫情严重程度对其捐赠意愿的影响没有显著差异.2)群体认同和关注他人具有相反的中介作用,其掩盖了潜在捐助者所在地的疫情严重程度对其捐赠意愿的影响;本地疫情严重程度一方面会增强个体的内群体认同继而正向影响捐赠意愿,另一方面会使个体减少关注他人继而减弱其捐赠意愿.3)威胁情境影响过程中,区域文化取向调节了内群体认同的正向中介作用和关注他人的负向中介作用.具体而言,相较于偏个体主义,当区域文化取向为偏集体主义时,本地疫情严重程度对于内群体认同的正向影响能够增强,对于关注他人的负向影响能够减弱.     

Lifetime Buy Decisions with Multiple Obsolete Parts

Life‐cycle mismatch occurs when the life cycles of parts end before the life cycles of the products in which those parts are used. Lifetime buys are one tactic for mitigating the effect of part obsolescence, where a quantity of parts is purchased for the remaining life of a product. We extend prior work that determines optimal lifetime buy quantities for one product with one obsolete part by providing an analytic solution and two simple heuristic policies for the optimal lifetime buy quantities when many parts become obsolete over a product's life cycle. We determine which of our two heuristics is most accurate for different product life cycles, which yields a metaheuristic with increased accuracy. That analysis also reveals critical perspectives in making lifetime buy decisions with nonstationary life‐cycle demand patterns.

考察了语言多样性对分析师盈余预测质量的影响,以及这种影响如何因员工教育水平的不同而变化.基于中国上市公司的实证检验结果显示,语言多样性显著降低了分析师盈余预测质量,但是随着公司员工受教育水平提高,语言多样性对分析师盈余预测质量的负面影响有所减弱.进一步研究发现,分析师与CEO间的校友关系增强了员工教育水平对语言多样性与分析师盈余预测准确性之间关系的正向调节作用.研究结论一定程度上丰富了分析师私有信息获取及其影响机理以及社会关系等方面的文献,而且还可帮助投资者、监管者等利益相关方更好地理解分析师行为,促进资源合理配置,增强资本市场的有效性等方面具有一定的启示意义.     

Approximations and Heuristics for the "Cause-Modified" Life Table

Life-table analysis can help to gauge the lifetime impacts that accrue from modifications to (age-specific) baseline mortality. Modifications of interest include those stemming from risk-factor-related exposures or from interventions. The specific algorithm used in these analyses can be called a cause-modified life table (a generalization of the cause-deleted life table). The author presents an approach for approximating that algorithm and uses it to obtain remarkably simplified expressions for approximating three indices of common interest: life-years lost (LYL), excess lifetime risk ratio (ELRR), and risk of exposure-induced death (REID). These efforts are restricted to the special case of multiplicative increases to baseline mortality (modeled as an excess rate ratio, ERR). The simplified expressions effectively "break open" what is often treated as a "black-box" calculation. Several insights result. For a practical range of risk factor impacts (ERRs), each index can be related to the ERR as a function of a baseline summary statistic and a "characteristic number" specific to the population and cause of interest. Conveniently, those numbers help form "rules of thumb" for translating among the three indices and suggest heuristics for extrapolating indices across populations and causes of death.     

Generalized Utilitarianism and Harsanyi's Impartial Observer Theorem

Harsanyi's impartial observer must consider two types of lotteries: imaginary identity lotteries (“accidents of birth”) that she faces as herself and the real outcome lotteries (“life chances”) to be faced by the individuals she imagines becoming. If we maintain a distinction between identity and outcome lotteries, then Harsanyi‐like axioms yield generalized utilitarianism, and allow us to accommodate concerns about different individuals' risk attitudes and concerns about fairness. Requiring an impartial observer to be indifferent as to which individual should face similar risks restricts her social welfare function, but still allows her to accommodate fairness. Requiring an impartial observer to be indifferent between identity and outcome lotteries, however, forces her to ignore both fairness and different risk attitudes, and yields a new axiomatization of Harsanyi's utilitarianism.     

Unemployment Duration of Spouses: Evidence From France

This paper analyses the conditional probability of leaving unemployment of French married individuals from 1991 to 2002. We find that the effect of spousal labor income on unemployment duration is asymmetric for men and women. In particular, the probability of men to find a job is increasing in wife's labor income, while it is decreasing in husband's earnings for women. To adjust for endogenous selection into marriage, we use the quarter of birth as an instrumental variable for the spousal wage. Finally, we show that introducing a breadwinner stigma in a joint job search model generates the positive correlation observed for men in the data.
