The determinants of time off work after childbirth

Relatively little is known about the role that leave policies--family, parental, or maternity-leave policies--play in facilitating time off work after childbirth. Yet time off is a critical element of leave policies, as it facilitates the mother's recovery from childbirth and promotes maternal-infant attachment. Using data from Minnesota, the state with the highest rate of female labor force participation, we examine the extent to which policies, relative to personal, job, and workplace characteristics, determine the duration of women's childbirth-related leaves from work. A random sample of women identified from vital statistics records is used to estimate the relationship between leave policies and time off work after childbirth. Of our sample 85 percent had access to some paid leave benefits, although only 46 percent had paid maternity leave benefits. The difference in duration of leave between women with and without paid leave policies was approximately four weeks, a substantial difference for most women and their infants. Paid leave policies and spousal earnings as primary determinants of maternal time off work, suggest problems in the use of unpaid leave for economically vulnerable women.     

Sex differences in the causes of adolescent suicide ideation

A model that incorporates both socioenvironmental and psychological factors was developed in an attempt to explain adolescent suicide ideation. A sample of 407 high school students was used to test the model. Most of the previous research on the causes of adolescent suicidal behavior has not used multivariate data analysis techniques and has failed to explore sex differences. Results of the present study suggest that these are important omissions. Although significant at the zero-order level, factors such as self-esteem and interpersonal problems at school were not related to suicide ideation when the effects of the other explanatory variables were controlled. The incidence of suicide ideation was higher for females. Emotional problems and involvement in delinquent behavior were important predictors of ideation for females, while employment problems were the most potent predictor for males.Received his Ph.D. from Florida State University.

The institutions of economic freedom and entrepreneurship: evidence from panel data

This paper provides new evidence on the determinants of entrepreneurship across countries. The paper investigates the relationship between the institutional setting, in terms of economic freedom, and entrepreneurship, measured by self-employment, in a panel data setting covering 23 OECD countries for the period 1972–2002. The measure of economic freedom includes five aspects: size of government, legal structure and security of property rights, access to sound money, freedom to trade internationally, and the regulation of credit, labour and business. The empirical findings show that a smaller government sector, better legal structure and security of property rights, as well as less regulation of credit, labour and business tend to increase entrepreneurship.     

Power transition in Northeast Asia: U.S.-China security perceptions and the challenges of systemic adjustment and stability

This article argues that the rise of China and the changing North-east Asian balance of power are creating the classical adjustment problems of Great Power international relations historically associated with power transitions and that three types of misperceptions across five important issues in the Sino-American security relationship are interfering with the prospects of achieving the systemic adjustments required for long-term stability. Power transition and the rise of China are seen as potentially undermining stability in four ways: (1) by generating security dilemmas and arms races, (2) by contributing to increased incidence of conflicting security interests, (3) by aggravating South china Sea maritime disputes, and (4) by undermining Chinese domestic stability in a manner which potentially results in a hostile regime that adopts an aggressive foreign policy coming to power at some point in the future. Systemic adjustment is defined as the process by which major powers peacefully reconcile their opposing interests and is viewed as being an essential feature of stability over the long term. The article argues that three types of misperceptions concerning: (1) salient issues, (2) security interests, and (3) the influence of domestic politics on foreign policy are manifesting themselves in misunderstandings of five security issues that are impeding the systemic adjustment process. These five issues are: (1) the nature of post-cold war Sino-American security relations and international politics, (2) the role of democracy and U.S. human rights in foreign policy, (3) the significance of China’s South China Sea policy, (4) Middle East diplomacy and arms sales, and (5) nuclear weapons and arms control policy. The article concludes with a discussion of policy implications that stresses the importance of consultation and dialogue to reduce misperceptions.
