GENDER EARNINGS DIFFERENCES IN CHINA: BASE PAY,PERFORMANCE PAY,AND TOTAL PAY

We utilize a data set that has not been used in literature—the Life Histories and Social Change in Contemporary China (LHSCCC)—to provide new evidence on male‐female pay differences in China. The data set not only enables us to control for a wide range of pay‐determining characteristics but also is the first to enable an analysis of the different components of pay (e.g., base pay and performance pay) as well as for total pay. We find: (1) Women receive about three‐quarters of male pay for each of the dimensions of base pay, performance pay, and total pay, before adjusting for the effect of different pay‐determining factors; (2) Approximately two‐thirds of the gap reflect the fact that females tend to be paid less than males for the same wage‐determining characteristics (often labeled as discrimination), while about one‐third reflects the fact that males have endowments or characteristics that tend to be associated with higher pay, especially supervisory responsibilities, general labor market experience, occupational skills, education, and membership in the Communist party; (3) Marriage has a large positive effect on the earnings of women in China (and none for men), but childcare responsibilities for children under the age of 6 have a large negative effect on the earnings of women although these are offset almost completely if an elder family member is present, highlighting that childcare responsibilities disproportionately fall on women unless an elder family member is present; (4) Pay premiums for higher level skills and higher supervisory ranks are remarkably small for both males and especially females; (5) With respect to the unexplained or “discriminatory” portion of the gap, females get a huge pay penalty for simply being female, but a substantial portion of this gets offset by the higher pay premium they receive for such factors as Han ethnicity, being married, and education. This suggests that discrimination tends to occur in the form of a pay penalty for simply being female and not from lower returns to the same endowments of pay‐determining characteristics.

Gender pay differentials during the transition in Poland*

This paper assesses the relative economic welfare of women during the transition in Poland. After providing an account of gender differences in several labour market outcomes we analyse the male‐female wage differential over the period 1993–97. We find that there is almost no change in the wage gap, that most of the explained portion of the wage gap may be attributed to industrial and occupational segregation, and that a substantial portion of the wage gap remains unexplained. We briefly discuss possible socio‐economic explanations for our findings.     

Sex Discrimination and Occupational Segregation in the Australian Labour Market*

This paper explores the implications of the difference between the occupational distribution for males and females in a joint model determining earnings and occupation. The male/female wage differential is evaluated for a number of broad occupational classifications. This is followed by an evaluation of the role and relative importance of inter-occupational and intra-occupational effects as contributors to the overall male/female wage differential The main conclusion following from the econometric results is that intra-occupational effects dominate Thus, policies which attempt to address the gender wage differential by re-allocation of labour across occupations are unlikely to solve the problem.     

Male–female wage discrimination in Chinese industryInvestigation using firm‐level data1

We use firm‐level data to analyze male–female wage discrimination in China's industry. We find that there is a significant negative association between wages and the share of female workers in a firm's labour force. However, we also find that the marginal productivity of female workers is significantly lower than that of male workers. Comparing wage gaps and productivity gaps between men and women, we notice an intriguing contrast between state‐owned enterprises (SOEs) and private firms. The wage gap is smaller than the productivity gap in SOEs, while the converse is true for private firms. These results suggest that women in the state sector receive wage premiums, whereas women in the private sector face wage discrimination.     

Sex Differences in the Ultimatum Game: An Evolutionary Psychology Perspective

In the two-person ultimatum game, an allocator is required to split a given sum of money with a recipient. Subsequently the recipient can either accept or reject the offer. If it is accepted, both players receive their respective splits, while if it is rejected neither of them get anything. Using evolutionary psychology as the theoretical framework, we predicted and found that males made more generous offers when pitted against a female as opposed to a male. While females made equal offers independently of the sex of the recipient. That male allocators are altruistic towards female recipients and competitive with male recipients is construed as a manifestation of social rules, which evolve from the male pre-disposition to use resources for attracting mates. In contrast, females have not evolved such a pre-disposition, and thus, female allocators are more concerned about fairness when making offers to recipients. Several alternate explanations of the above findings are discussed and the evolutionary explanation is concluded as the most parsimonious one. Other potential moderators that are amenable to evolutionary explanations, namely, physical attractiveness, age and ethnicity of participants, are also discussed in this context.

The relationship between the markets for health insurance and medical malpractice insurance

This article evaluates the interdependence of medical malpractice insurance markets and health insurance markets. Prior research has addressed the performance of these markets, individually, without specifically quantifying the extent to which they are linked. Increasing levels of health insurance losses could increase the scale of potential malpractice claims, boosting medical malpractice losses, or could embody an improvement in medical care quality, which will reduce malpractice losses. Our results for a state panel data set from 2002 to 2009 demonstrate that health insurance losses are negatively related to medical malpractice insurance losses. An additional dollar of health insurance losses is associated with a $0.01–$0.05 reduction in medical malpractice losses. These findings have potentially important implications for assessments of the net cost of health insurance policies.     

Gender Inequality in the Provision of Employer-Supported Education

Abstract
Only 27 per cent of females compared with 51 per cent of males undertaking programs of education in Australia do so with financial or other support from their employer. Using data from the How Workers Get Their Training, Australia 1989 survey, an analysis of this differential is undertaken by investigating the effects of dependent children and by controlling for differences in other characteristics between males and females. Although after controlling for these differences the absolute difference between males and females was small, 3.5 percentage points, the estimated bias in favour of males accounts for over 80 per cent of this differential; that is, less than 20 per cent of the differential can be accounted for by differences in male and female characteristics .     

中国城市劳动力市场上的性别工资差异

本文描述了中国城市劳动力市场上男女在行业获得和工资上的差异,并且用计量方法对工资差异进行了分解。分解结果表明,男女工资差异主要由同类行业内工资差异引起,而由于两者行业分布不同而带来的工资差异不大;歧视是造成性别之间的工资差异的主要原因,人力资本所起的作用很小。由此,缩小行业内的工资差异,消除对女性的歧视,是缩小工资性别差异的重要途径。     

Courts,scheduled damages,and medical malpractice insurance

We study how the functioning of the judicial system affects the availability and affordability of medical liability insurance, as proxied by the number of insurers and the premiums paid. We use two unique datasets collected in Italy from 2000 to 2010. Using the first dataset—insurance contracts for hospitals—we estimate the average treatment effect of schedules on insurers and premiums paid, conditional on judicial efficiency and proxied by different measures. Our identification rests on the partial overlap between healthcare districts and judicial districts, meaning that the caseload of a court and malpractice events at the healthcare provider level are not perfectly correlated. On average, the adoption of schedules does not produce any significant effect on insurers or on premiums paid. However, adopting schedules has a robust and significant effect on the number of insurers, but only in inefficient courts. We further investigate these findings using a second dataset comprising 17,578 malpractice insurance claims. We find evidence of a composition effect among claims that is triggered by higher levels of judicial inefficiency: As a court’s inefficiency increases, the likelihood for a case to not be decided on the merits decreases and the levels of reserve and recovery per claim decrease.     

Gender Earnings Differential in Urban China

This study uses survey data collected from five large cities in China to describe and decompose the earnings difference between female and male workers. The results indicate that the main source of lower earnings for females lies in unequal pay within sectors, and that the earnings gap due to differences in sectoral attainment is relatively small. The results also reveal that most of the gender earnings differential is attributable to sex discrimination rather than to the gender difference in the endowment of human capital. Therefore, eliminating discrimination against females within individual sectors is effective in narrowing the gender earnings gap.     

Climate change, health and migration in urban China

In this paper, I empirically investigate the effect of climate change on health and migration in China. Using urban survey data sets from different Chinese cities, I find that an increase in female morbidity is associated with current high temperature change, especially for the symptom of frailty; past hot weather is related to the exacerbation of health problems in women, and the effect on females is larger than that on males who migrate from rural areas to cities; past temperature change is also correlated with a higher probability of chronic symptoms for females. I also find that migration preference from a rural area to a city is correlated with avoiding exposure to hot weather shocks, which shows a regressive tendency. Finally, the migration preferences of male residents who migrate from one city to another city are not associated with the effects of past low temperature changes on health.     

On the predictive power of monetary exchange rate model: the case of the Malaysian ringgit/US dollar rate

Despite anecdotal and survey evidence suggesting the presence of discrimination against customers in stores, restaurants and other small-transaction consumer markets, few studies exist that identify or quantify the nature of any unequal treatment. We provide evidence from a field study of wait times in Boston-area coffee shops that suggests that female customers wait an average of 20 seconds longer for their orders than do male customers even when controlling for gender differences in orders. We find that this differential in wait times is inverse to the proportion of employees who are female and directly related to how busy the coffee shop is at the time of the order. This supports the conclusion that the observed differential is driven at least in part by employee animus and/or statistical discrimination rather than unobserved heterogeneity in the purchasing behaviour of female customers.     

Union wage effects in Australia: an endogenous switching approach

Using data from the Household and Labour Income Dynamics Australia (HILDA), an endogenous switching model is employed to analyse union wage effects in Australia between 2001 and 2013. An advantage of this approach is that the decision to join a union is treated as potentially endogenous, a function of the wage differential between union and non-union workers, rather than exogenous as is the case in virtually all previous Australian studies. The article finds that the decision to join a union is highly sensitive to the wage differential between union and non-union workers. The article also finds that male (female) union workers with average union characteristics earn 12% (18%) more than male (female) non-union workers with average non-union characteristics. However, a decomposition analysis finds that this difference is due to union workers having better human capital endowments than their non-union counterparts. In addition, they also receive a lower return for those endowments. These decomposition results suggest that union wage effects in Australia may be negative, rather than the small positive effects typically found in the Australian literature.     

EVALUATING MEDICAL MALPRACTICE REFORMS

Which of the tort reforms enacted during the mid-1970s to alleviate the medical malpractice litigation crisis have succeeded? Under some circumstances, the frequency and disposition of claims may indicate how reforms affected key policy variables such as the number of injuries and costs of litigation. But potential pitfalls exist in using claims data to evaluate tort reforms. In this paper, we identify and discuss these problems, review recent findings, and offer guidance to improve policy analysis.     

Publicly Provided Goods and Intrafamily Resource Allocation: Female Child Survival in India

The paper examines the problem of excess mortality of females in India. The determinants of gender–specific child survival are investigated through the traditional household production model pioneered by Becker, which is extended to include publicly provided goods as fixed inputs in production decisions. The introduction of government–provided goods provides an avenue for investigating the influence of the state on household decisions. Gender–specific child survival equations are estimated using a robust "seemingly unrelated regression" method. Results using 1981 Indian Census data indicate that increases in female literacy and female labor force participation increase female child survival in rural India. Furthermore, higher ratios of female to male medical technicians are associated with higher female child survival relative to males. This paper demonstrates that a large and effective role exists for government to address excess female morality.     

Medical practice and malpractice litigation in an evolutionary context

We model the interactions between the behaviors of physicians and patients, subject to clinical and legal risks, by means of evolutionary game theory. We propose an original game in which patients may sue their physician for medical malpractice, and physicians have to choose between two alternative treatments, with different levels of benefits and risks. The safer treatment is also the less effective, therefore its provision corresponds, under the assumptions of our model, to practicing negative defensive medicine. We study the Nash equilibria, test their stability in the replicator dynamics, and analyze their welfare properties. We find that the accuracy of the judicial system plays an important role, with possible counter-intuitive effects related to legal reforms. If the court is not sufficiently accurate, defensive medicine can be favored, paradoxically, by an increase in the probability that defensive physicians are sanctioned by the court. A similar outcome can be generated also by an increase in the compensation paid to patients by physicians, when sanctioned for medical malpractice.     

Remittances and labour allocation decisions at communities of origin: the case of rural Mexico

From a theoretical perspective, the effect that remittances have on the labour decisions of those that receive them is ambiguous; the empirical evidence reported in the literature is mixed and shows, unsurprisingly, that the net effect of remittances on labour supply is context-dependent. We contribute to this literature by using a detailed data set for rural Mexico that allows us to understand how remittances reshape rural livelihoods by modifying labour allocation decisions. Following previous evidence, we analyse female and male responses separately. Our results show that the income effect of remittances dominates male labour allocation decisions: the probability of participating in the labour market and the total number of hours worked decrease with remittances. We find no effect for female labour allocation decisions. The effects are not uniform across the different productive activities and remittances seem to be contributing to a trend in which Mexican rural inhabitants increasingly move away from agriculture- or nature-based activities. This reinforces the direct effect that emigration has in terms of a reduction in total supply of local labour.     

Reverse moral hazard of liability insurers: evidence from medical malpractice claims

This study investigates putative differences in the legal defense of medical malpractice claims between liability carriers with distinct ownership forms: doctor-controlled and commercial-stock. The scope of a carrier's legal defense is determined by claim characteristics, such as injury severity and liability, and possibly the doctor's private costs from settling or losing a claim. When a carrier does not internalize the doctor's private costs from losing or settling a claim, then a conflict of interest arises as the carrier provides a lower level of legal defense than preferred by the doctor (i.e., reverse moral hazard). The perception is that doctor-sponsored carriers mitigate such conflicts of interest. If this is the case, we should expect to see differences in the amount spent by the carrier in defense of the doctor and the propensity to settle claims. To test these expectations, we use medical malpractice claims filed in Florida between 1985 and 1990. We indeed find differences in legal defense in terms of amount spent on legal defense and settlement rate between carriers with different ownership. The doctor-sponsored carrier we investigated was less likely to settle out-of-court, and did spend more on a doctor's legal defense than stock carriers.     

Measuring the extent of earnings discrimination: an update

Ordinary least squares (OLS) regression and data from the March 1990 Current Population Survey are used to estimate yearly earnings averages for white males, white females, black males and black females. In order to test for the possible existence or gender and/or race discrimination, earnings estimates are decomposed, using the tradional Oaxaca (1973) and Blinder (1973) methodology. In comparing these results with those from Carlson and Swartz (1988, using 1979 data), we find that overall and unexplained residual differences have declined quite substantially, but that they still favour white males. We then incorporate an extension of the traditional methodology (Jackson and Lindley, 1989) which allows for testing for the significance of enexplained residuals, and for jointly testing for the significance of residual effect components, the constant and coefficient effects. These results call into question the unambiguous conclusion that earnings differentials uniformly favour white males. Strong support is found for the Jackson–Lindley contention that significant and positive residuals may have have offsetting signs. More specifically, where males appear to receive an entry level premium, as measured by constant effect differentials, but other groups appear to receive favourable treatment as measured by response rates to changes in independent variables (the coefficient effect). This result suggests that efforts may be underway to ‘make up’ for the entry level white male premium.
