The Role Of Snap And Habit Formation On Household Consumption Behavior, Shaheer Burney

Theses and Dissertations--Agricultural Economics

This collection of essays examines the impact of two antecedents of household food consumption: SNAP and habit formation to nutrients. Household food choice invariably plays a substantial role in health outcomes such as obesity. Low-income households may be especially vulnerable to obesity as they face a more restricted set of food choices due to income constraints and may have less information on healthy eating relative to high-income households. This dissertation unravels this dynamic by providing causal estimates of the effect of two major determinants of food choice.

Chapter 2 and chapter 3 test the impact of SNAP participation on consumption …

Natural Resource, Regional Growth, And Human Capital Accumulation, Na Zuo

Theses and Dissertations--Agricultural Economics

The dissertation research will comprise three essays on the topic of the resource curse hypothesis and its mechanisms. The phenomenon of low economic growth in resource-rich regions is recognized as the “resource curse”. These essays will contribute to an understanding of the regional resource-growth relation within a nation.

Essay one tests the resource curse hypothesis at the U.S. state level. With a system of equations model, I decompose the overall resource effect to account for the two leading explanations — crowding-out and institution effects, thus investigate whether the institutions mediate the crowding-out effects. I did not find evidence of an …

Environmental Values, Stated Preferences, And Hypothetical Bias, Jerrod M. Penn

Theses and Dissertations--Agricultural Economics

Contingent Valuation (CV) methods are a primary tool in environmental economics to ascertain non-use or other values not observable through existing market mechanisms. Because common CV approaches typically rely on hypothetical answers from surveys in order to generate welfare estimates, these are often labelled stated preferences. Results from stated preference methods often diverge from those obtained when actual preference or behavior are involved. This divergence is commonly known as Hypothetical Bias (HB). This dissertation addresses HB as it applies to environmental applications. To begin, a meta-analysis using a sample of studies many times larger than previous works was performed. Its …

Three Essays On Food Safety Regulations And International Trade Of Agricultural Products, Jun Ho Seok

Theses and Dissertations--Agricultural Economics

This dissertation investigates food safety regulations and international trade of agricultural products dividing into three aspects: the signalling effect from U.S. strict food safety regulations on U.S. vegetable exports, political determinants of sanitary and photosanitary non-tariff barriers, and the impact of trade barriers on employment in developing countries. In chapter 2, we investigate the impact of high U.S. maximum residue limit (MRL) standards on U.S vegetable exports to 102 countries utilizing the hierarchical model. MRL, which is one of non-tariff barriers with respect to food safety, is applied to home and foreign countries at the same time. Thus, firms in …

Agricultural Input Intensification, Productivity Growth, And The Transformation Of African Agriculture, Didier Y. Alia

Theses and Dissertations--Agricultural Economics

This dissertation studies agricultural input intensification, defined as the increased use of modern inputs such as hybrid seeds, mineral fertilizer, herbicide, and pesticide in African agriculture. It also analyses the potential of this intensification to accelerate productivity growth and tests the effectiveness of two policies, input subsidies and land reforms, in promoting it and consequently in increasing crop yield. In the first essay, we argue that to create the conditions for the emergence of a green revolution in Africa, modern agricultural technologies have to be adopted as a package, not in a piecemeal fashion. This argument is consistent with a …
