Three Essays On Health, Food, And Agricultural Economics, Saber Feizy

Theses and Dissertations--Agricultural Economics

This dissertation comprises three distinct but interrelated projects that explore the intersection of agriculture, nutrition, and economics. The first project investigates the impact of Community Supported Agriculture (CSA) food programs on the health outcomes of its participants. Using fixed effects models and a matching algorithm, the study finds that while conventional fixed effects models indicate a significant effect of CSA participation on diet-related medical expenditures, our modified time-heterogenous fixed effects model did not find a meaningful effect. The results of the matching method are consistent with those of our modified model.

The second project examines racial disparities in the prevalence …

Consumer Measures Of Local Food System Performance And Shopping Behavior Across Covid, Azita Varziri

Theses and Dissertations--Agricultural Economics

This dissertation consists of three essays: In the first essay, we utilize a Principal Component Analysis (PCA) to measure the residents’ perceptions of the local food system performance. Local food system (LFS) components are classified into related measures that may help explain the overall performance scores provided. LFS performance measures are explored across 15 different communities in the U.S. South. The second essay explores the awareness and performance differences toward farmers markets, including the markets themselves and the corresponding local food product quality, product diversity, and markets infrastructure across different age-range groups and community sizes in Southern states. Finally, in …

Theses and Dissertations--Agricultural Economics

The first chapter of this dissertation examines price discovery and volatility spillovers in the coffee spot-futures commodity market over the post-ICA period by employing the PT-IS and bivariate EGARCH models. This research covers two actively traded coffee types, Arabica and Robusta, and utilizes daily time-series price data over 1990:01-2020:04 for Arabica and over 2008:01-2020:04 for Robusta. The empirical results indicate that coffee spot markets play a dominant role in the coffee price discovery for both Arabica and Robusta. The results also show volatility spillovers take place from the coffee spot market to the futures markets. This study helps small-scale coffee …

Animal and Food Sciences Faculty Publications

Replacement heifer rearing is critical for the future of dairy operations, to improve genetic merit and maintain herd size. A myriad of options exist on how to manage, feed, and ultimately raise replacement heifers. Pasture is perceived to offer optimal welfare and an economical housing system for replacement animals, but confinement systems are gaining popularity. This study investigates the costs associated with replacement heifer management decisions from birth to calving, considering the factors of housing systems, labor, feed, and health. The objective of this study was to develop an economic model to determine the cost of raising a replacement heifer …

Three Essays On The Application Of Machine Learning Methods In Economics, Abdelaziz Lawani

Theses and Dissertations--Agricultural Economics

Over the last decades, economics as a field has experienced a profound transformation from theoretical work toward an emphasis on empirical research (Hamermesh, 2013). One common constraint of empirical studies is the access to data, the quality of the data and the time span it covers. In general, applied studies rely on surveys, administrative or private sector data. These data are limited and rarely have universal or near universal population coverage. The growth of the internet has made available a vast amount of digital information. These big digital data are generated through social networks, sensors, and online platforms. These data …
