This paper examines the effects of regional characteristics on spread highly pathogenic avian influenza (HPAI) during Korea's 2016-2017 outbreak. A spatial econometric model is used to determine HPAI dispersion using data from 162 counties in Korea. Results indicate existence dependence, suggesting that occurrence a county significantly influenced by neighboring counties. We found larger size poultry, including laying hens, breeders, and ducks are associated with greater incidence HPAI....

The Korean agricultural sector faces increasing challenges such as an aging population, labor shortages, and the liberalization of markets. To overcome these challenges, government has striven to enhance competitiveness agriculture by introducing AI-based technologies sector, labeling this smart farming. This study estimates farm-level benefits adopting farming technologies, robotic milking systems, in dairy farms. are estimated comparing productivity (i.e., savings input, increased calf...

This study analyzes the self-reported intake of dietary supplements (DS) and their effects on perceived health well-being from a survey with 1210 adult respondents in Korea. To account for selectivity bias observable confounders, we use propensity score matching (PSM) model. Our findings show that demographics, concerns, family history disease, frequency hospital visits, regular exercise are positively associated DS among consumers. Results PSM leads to significant improvements takers...

This study analyzed consumers’ characteristics for health functional food intake. A consumer survey was conducted to look various factors influencing the consumption of food. Heckman selection model is used control sample bias. The probit results show that women, married person, smaller family members, and higher income were more likely purchase In addition, interest in disease history, number visits hospital lead age, income, longer intake period induce amount These could be utilized...

The South Korean livestock industry has increased in scale and production, generating positive impacts on the national economy. However, externalities, primarily malodor, have subsequently led to conflicts between producers affected communities. This study estimated households' willingness-to-pay (WTP) for government subsidies help address malodor using a contingent valuation method (CVM) derived from double-bounded dichotomous choice model. annual average household WTP was at 29,206 won...

Highly pathogenic avian influenza (HPAI) outbreaks are a threat to human health and cause extremely large financial losses the poultry industry due containment measures. Determining most effective control measures, especially culling radius, minimize economic impacts yet contain spread of HPAI is great importance. This study examines factors influencing probability farm being infected with during 2016–2017 outbreak in Korea. Using spatial random effects logistic model, only few commonly...

Evaluating the effectiveness of government programs is an important topic for economic developers. One popular example U.S. Economic Development Administration’s (EDA) Public Works Program, initially established in 1965. Haughwout (1999) found a significant positive impact EDA public works projects completed 1990 on county-level employment over period to 1994. The authors reexamine whether this effect continues hold 20 years later by replicating Haughwout’s specification using data from 2010...

Hay is an important field crop in the U.S., with over 54 million harvested acres 2015. In many southern states, hay input for cattle production, and reducing forage costs crucial improving profitability of livestock operations. It well known that yields quality are significantly influenced by weather variations, which can have different impacts across geographical regions years. This study quantifies possible heterogeneous yield responses to variations Oklahoma yields. The paper uses panel...
