Essays in Household and Demographic Economics

This dissertation consists of three empirical studies that are believed to provide new contributions to the literature exploring the determinants of children/adolescents achievement test scores (Chapter 2), adolescent health risk behaviors (Chapter 3), and children time use patterns (Chapter 4). The second and third studies look at the separate roles of fathers and of mothers in influencing outcomes, wherein parental time is the resource input of interest quantitatively measured and directly derived from time diaries. The last chapter looks at the time allocation of children and how it varies according to child and household characteristics.

How Important Are Intergenerational Transfers of Time? a Macroeconomic Analysis.

This paper examines the implications of intergenerational transfers of time and money for labor supply and capital accumulation. Although intergenerational transfers of time in the form of grandparenting are as substantial as monetary transfers in the data, little is known about the role and importance of time transfers. In this paper, we calibrate an overlapping generations model extended to allow for both time and monetary transfers to the US economy. We use simulations to show that time transfers have important positive effects on capital accumulation and that these effects can be as significant as those of monetary transfers. However, while time transfers increase the labor supply of the young, monetary transfers produce an income effect that tends to decrease work effort. We also find that child care tax credits have little impact on parental time and money transfers, but that a universal child tax credit would increase the welfare of the rich while the poor would benefit from a means-tested program.

Labor Market Institutions and Gender Differences in Wage Inequality.

In this paper, we present graphical and quantitative evidence on the important role played by changes in labor market institutions on the rise in wage inequality in the United States during the 1980s. We show that the decline in the real value of the minimium wage and in the rate of unionization explains over a third of the rise in inequality among men.

Attitudes about work practices, time allocation and publication output: profiles of U.S. marketing academics

This study examines attitudes of U.S.-based Academy of Marketing Science members toward teaching, research, participation in administration (including service), and academic promotional issues. Individuals were grouped using Ward’s and K-means clustering procedures, which revealed four groups—established academics, research-focused academics, less satisfied midcareer academics, and satisfied teachers. Clusters were further profiled according to the amount of time spent on teaching, research, and administration; research output; and individual demographic and institutional characteristics. Overall, clusters were generally dissatisfied with a range of work-related issues, with workload stress appearing as an issue that needs to be addressed within marketing academia.

Attitudes about work practices, time allocation and publication output : profiles of Australasian marketing academics

The Australasian tertiary education sector has undergone significant organizational and cultural changes, which have increased pressures on academics to undertake a range of additional activities while at the same time improving research performance. These pressures impact on individuals in different ways, although there may be some groups or clusters of individuals within institutions with common characteristics. Managers may need to develop different sets of management strategies and policies to assist each group of academics to deal better with these pressures and improve their individual performance. The paper examines Australasian marketing academics’ perceptions of their work environments and whether these perceptions result in differing clusters of individuals who might also vary based on their research performance, time allocated to different academic roles, and their professional and demographic characteristics. Sixty-eight members of the Australian and New Zealand Academy of Marketing responded to a survey using a modified version of an instrument developed by Diamantopoulos et al. (1992). K-means clustering procedure identified four groups of academics – “Traditional Academics,” “Satisfied Professors,” “Newer Academics,” and “Satisfied Researchers.” While only a few significant differences among clusters were identified in relation to time allocated to academic activities and research performance, it appears that clusters differ on several professional and demographic characteristics.

Examination of relationships between urban form, household activities, and time allocation in the Atlanta Metropolitan Region

A substantial body of research is focused on understanding the relationships between socio-demographics, land-use characteristics, and mode specific attributes on travel mode choice and time-use patterns. Residential and commercial densities, inter-mixing of land uses, and route directness in conjunction with transportation performance characteristics interact to influence accessibility to destinations as well as time spent traveling and engaging in activities. This study uniquely examines the activity durations undertaken for out-of-home subsistence; maintenance, and discretionary activities. Also examined are total tour durations (summing all activity categories within a tour). Cross-sectional activities are obtained from household activity travel survey data from the Atlanta Metropolitan Region. Time durations allocated to weekdays and weekends are compared. The censoring and endogeneity between activity categories and within individuals are captured using multiple equations Tobit models. The analysis and modeling reveal that land-use characteristics such as net residential density and the number of commercial parcels within a kilometer of a residence are associated with differences in weekday and weekend time-use allocations. Household type and structure are significant predictors across the three activity categories, but not for overall travel times. Tour characteristics such as time-of-day and primary travel mode of the tours also affect traveler's out-of-home activity-tour time-use patterns.

Rank Regressions, Wage Distributions and the Gender Gap.

In this paper, we model the interactions between the distribution of male and female wages under the assumption that any change in the wage distribution of women must be offset by an opposite change in the wage distribution of men.
