Gender differences in self‐employment

This paper examines the factors that influence transitions into self‐employment, paying particular attention to gender differences. We find that: (i) men are more responsive to the wage differential between wage/salaried employment and self‐employment; (ii) liquidity constraints are more important for men; and (iii) the link between father's self‐employment status and the probability of self‐employment is stronger for men. Taken together, these results suggest that, for women, self‐employment is a closer substitute for part‐time work and labour‐market inactivity than it is for men. We attribute such differences to the different labour market opportunities and occupational strategies of women.     

Labor Market Discrimination against Women with Disabilities

This article estimates the extent of wage discrimination and, for the first time, the employment effects of wage discrimination, against women with disabilities. In 1984, more than one-half of the offer wage differential between disabled and nondisabled women is attributable to discrimination, but the absolute wage differential is small. The results suggest that wage discrimination related to disability tends to be most severe for a relatively small group of women with impairments against which prejudice is most intense. There is a large difference between the employment rates of disabled and nondisabled women but only a small part of the differential is attributable to the disincentive effects of wage discrimination. The results also show that women with disabilities face a double burden of gender- and disability-related discrimination, but do not show that gender-related discrimination is worse for women who have a disability.     

Joint Estimation of Factor Sensitivities and Risk Premia for the Arbitrage Pricing Theory

The APT is represented as a multivariate regression model with across-equations restrictions. Both observed and unobserved (latent) macroeconomic factors are included, thus generalizing and unifying two previous strands of literature. Large portfolios representing unobserved factors are treated as endogenous, and nonlinear 3SLS estimates are shown to differ sharply from estimates that ignore this endogeneity. Using monthly stock returns and six factors, we cannot reject January effects. The following results are invariant with respect to the inclusion of January effects: we reject the CAPM in favor of the APT; however, we cannot reject the APT restrictions on the linear factor model.     

ARE SURVEYS OF EXPERTS UNBIASED? EVIDENCE FROM COLLEGE FOOTBALL RANKINGS

Policymakers are frequently interested in soliciting unbiased information regarding alternative policies, and expert surveys can be influential. As ranking policies is an often subjective process, there is always the concern of bias, both intentional and not. Expert bias is difficult to discern in the policy world, but surveys of expert opinion are compiled and “tested” for accuracy weekly in college football, allowing for hypothesis testing. Although previous research has used college football rankings to determine the ability of surveys to incorporate relevant information, this article examines the Associated Press and American Football Coaches' Association rankings for evidence of systematic bias. Specifically, more than 1,300 games from the 2003 to 2008 regular seasons are tested for factors that are systematically correlated with upsets. Both polls predict the winner nearly 80% of the time, and although there is evidence of systematic conference bias, correcting the rankings would only improve the accuracy of the polls by about 1%. There is no evidence of a bias favoring “big market” teams, nor teams that have strong journalism programs or are from the East Coast. (JEL D4, L8)     

Impact of Married Women's Employment on Individual Household Member Expenditures for Clothing

Family member and per capita clothing expenditures are estimated via tobit, using 1980–1981 Consumer Expenditure Survey data. Occupation categories are developed and implicit wage rates imputed for each wife in the sample. Employed-wife households have higher expenditures for clothing than do nonemployed-wife households and wife's occupation differentially affects family member expenditures. Wife's implicit wage is not significant, while wife's unearned income has a positive impact on all categories of expenditures except for infants. These results indicate that it is not possible to generalize across family members about the influence of income and socio-demographic variables on clothing expenditures.     

Consumer attitudes towards the quality of domestic and imported apparel and footwear*

Due to increased imports and increasingly competitive consumer markets, this study was undertaken to determine consumers' quality images of Canada and the major countries from which men's, women's and children's clothing, and men's and women's footwear were imported. A self-completed mail survey of 635 members of a consumer panel yielded demographic representation from English- and French-speaking men and women. The Fishbein-Rosenberg multi-attribute model was used to compute consumers' attitudes towards countries as producers of clothing and footwear. Consumers had high quality images of Canadian-, U.S.- and European-made clothing and footwear. The styling of Italian-made shoes and French-made clothing was perceived as superior to Canadian-made products. All consumers were critical of the products from low-wage countries, particularly consumers with higher education, income and employment status. Implications were drawn emphasizing the need for consumer research and marketing strategies.     

POLICY EVALUATION IN THE PRESENCE OF OUTSOURCING: GLOBAL COMPETITIVENESS VERSUS POLITICAL FEASIBILITY

We analyze the effects of outsourcing in the presence of a minimum wage by presenting a general-equilibrium model with an oligopolistic export sector and a competitive import-competing sector. An outsourcing tax is politically popular because it switches jobs to unemployed natives. It is also economically sound because it raises national income. An export subsidy may or may not be justified on welfare grounds. Increased international competition has no effect on the level of outsourcing, but the direction of its effect on unemployment and national income depends on the relative factor intensities of the two sectors.     

Does Network Care Prolong Work Absences?

We used data on 120,000 workers with occupational injuries occurring in California, Connecticut, and Texas to analyze the effects of healthcare networks on postinjury durations of work absence. Controlling for selection and unobserved heterogeneity, work absences are shorter, all else equal, for network cases than for non‐network cases. The shorter durations could reduce lost productivity by more than $3.8 million (a 9% reduction in work loss days for non‐network cases) if network care were extended to the non‐network cases in our sample.
