Essays in labor economics

Leslie, Emily Catherine 01 May 2017 (has links)
This thesis considers how potentially vulnerable populations are affected by various economic and policy shocks. In the first chapter, I investigate the impact of natural resource booms on crime by estimating the effect of the coal boom and bust of the 1970s and 1970s on reported crime rates. I begin by demonstrating that changes in the value of coal reserves affected local economic conditions and population composition, both of which have theoretical and empirical links to crime. The net effect is theoretically ambiguous. The estimates suggest that the immediate impact of increasing the value of natural resources is to depress crime rates, primarily through changes in property crime, but these changes erode over time. My findings are consistent with an initial change in criminal activity in response to local labor market conditions that is subsequently offset by selective migration. Individuals who are charged with committing a crime often find themselves behind bars while their case is adjudicated. In the United States, over 400,000 individuals are in jail each day waiting for their criminal cases to be resolved. The majority of these individuals are detained pretrial due to the inability to post low levels of bail (less than $3,000). In chapter 2, my coauthor and I estimate the impact of being detained pretrial on the likelihood of an individual being convicted or pleading guilty, and their sentence length, using data on nearly a million misdemeanor and felony cases in New York City from 2009 to 2013. Causal effects are identified using variation across arraignment judges in their propensities to detain defendants. We find that being detained increases the probability of conviction by over seven percentage points by causing individuals to plead guilty more often. Because pretrial detention is driven by failure to post bail, these adverse effects disproportionately hurt low-income individuals. While some public policies create burdens that fall most heavily on low-income people and households, the public safety net is comprised of programs intended to protect and support this vulnerable population. In chapter three, my coauthors and I examine whether programs that provide vouchers to households can continue to influence behavior even after the household leaves the program. Using detailed scanner data, we test whether benefit vouchers received through the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) change household purchasing decisions and whether these changes continue to persist even after households are no longer eligible to participate in the program. In 2009, the package of goods available through WIC vouchers changed to include additional items and place nutritional restrictions on other items. Examining variation due to this package change, we show that the WIC vouchers change purchasing decisions consistent with the nutritional guidelines of the program. However, we find evidence of limited persistence post-eligibility, and that households exposed longer to the revised package are generally not more likely to continue to purchase these items after eligibility ends.

Fathoming the fathers in environmental education : a feminist poststructuralist analysis

Gough, Annette, annette.gough@deakin.edu.au January 1994 (has links)
The purpose of this study is to provide a feminist poststructuralist analysis of the dominant international discourses in environmental education, and how these have been realised in Australian national statements and in state policies over the past two decades, in terms of their implicit views about science, the environment, epistemology and education. The methodology of the study presents an argument for a 'politics of method' in the form of a research approach which reflects the ideology and intent of the study, i.e. an argument toward feminist poststructuralism as a methodology, but with elements of critical feminist research. Part of this methodology involves consideration of the gendered nature of language and discourses, particularly in the sciences. The argument is for the reconstituting of knowledge through feminist standpoint theory and the adoption of standards of 'strong objectivity'. In the spirit of its poststructuralist methodology the study presents three different stories (archaeologies) about environmental education: one told in terms of people, events and their outcomes; one told in terms of the changing views of education and how these were interpreted in environmental education; and the third told in terms of the emergence of ecofeminism as a parallel movement to environmental education and the emerging relationship between these two movements. These stories serve two purposes: to review the relevant literature in these three areas, and to provide the 'data' for later chapters. The discourses of environmental education, particularly those of the 'founders' and UNESCO documents, are then analysed from a poststructuralist perspective, followed by a feminist reconstruction of environmental education which argues for thinking from women's and other marginalized lives as a preferred strategy for environmental education, and develops research principles to explore this possibility. The conclusion reflects on the philosophical and theoretical issues engaged, and the methodological issues addressed, in the study.
