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

Three Essays On Price Analysis And International Trade, Wei Zhang
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 …
Three Essays On The Application Of Machine Learning Methods In Economics, Abdelaziz Lawani
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 …
The Effects Of Country Of Origin Image And Patriotism On Consumer Preference For Domestic Versus Imported Beef, Thong Meas
Theses and Dissertations--Agricultural Economics
Country of origin (COO) effect is a well-researched topic in the international marketing literature. It is well recognized that consumers are biased against imports, due to consumer ethnocentrism or patriotism tendency. However, the research on COO effects also suggests that consumers form certain image of origin countries (COO image) and favorable image, be it associated with the countries, their people, or general product quality, improves the evaluation and acceptance of foreign imports.
The publications related to COO effects which focus on consumer durables are abundant. However, the contrasting COO effects on food products are much less investigated. This study surveys …

Food Imports Under Foreign Exchange Constraints In The Cfa’S Franc Zone Of Sub-Saharan Africa (Ssa), Seydina Ousmane Sene
Theses and Dissertations--Agricultural Economics
To respond to the high imported food prices in their domestic markets, net food importing countries in the Communauté Financière Africaine (CFA) zone[1] are adjusting their import tariffs and homologate domestic prices of imported commodities such as rice, wheat, maize, and sugar. This research uses a multivariate specification of error correction model (VECM) of estimation to investigate the link between food imports, world price index of rice, wheat, maize and sugar, real effective exchange rates, domestic food production, GDP, and trade openness in the short and long run. The data are on each homogenous commodity from 1969 to 2012. …
