This study contributes to guidance for understanding farmland purchase and rent decisions in Korea via an analysis using a machine learning tool, Random Forests: A Supervised Machine Learning Algorithm. Farm Household Economy Survey is employed to predict the relationship between farmland acquisition and farm household economic characteristics. Our main findings are two folds. First, a farmland purchase decision is positively related to transfer incomes, the value of inventory & fixed assets, and the value of farmland that farmers owned. Second, a farmland rent decision is also positively associated with a rent paid in a prior year, revenue from field crops, inventory and agricultural assets, and transfer incomes.

In 2018, African Swine Fever (ASF) first broke out in China and had a noticeable effect on China's pork market and the entire meat market. This paper models China's meat market, including pork, beef, mutton, and poultry, and examines how the outbreak of ASF impacts structural changes in China's meat demand. We use the inverse almost ideal demand system (IAIDS) model and employ province-level meat consumption and price data to form the panel data set of 30 provinces of China from 2015 to 2020. Our results indicate that ASF has a significant impact on the demand for pork, poultry, and mutton. Based on the estimated price flexibilities and scale flexibilities, we find that the outbreak of ASF impacts structural change in China's meat demand. Furthermore, our results show the heterogeneity of the ASF's effects across different provinces in China.

An unexpected surge in sugar imports in 2008 under NAFTA resulted in a large U.S. sugar price fluctuation. This study explores the acreage decision for U.S. sugar beets in an environment where both price support and trade liberalization takes place at the same time. Our empirical analysis is based on county-level data for sugar beets and three substitute crops (corn, soybean and wheat) in twelve U.S. sugar beet growing states over 1997-2018. While we find that an increase in price fluctuation overall has adverse impacts on acreage, the results indicate that farmers respond to price risk differently before and after NAFTA and to the level of price risk. This suggests a need for more precise policy instruments that better protect against unexpected income loss rather than a fixed level of support and enable producers to deal with future extreme events.

This study analyzed the benefits of the B2B online agricultural exchange, which is promoted by the government for digital transformation in the distribution sector as the Fourth Industrial Revolution technology is introduced and the agricultural distribution environment is changing rapidly owing to COVID-19. Currently, the Korean government is conducting the national B2B online agricultural exchange, where sellers, including producer organizations and agricultural corporations, can make direct transactions and buyers, including public market wholesale corporations, intermediaries, and trade participants, can purchase agricultural products through the online platform, regardless of time and location.
Against this backdrop, we analyzed the potential benefits of the online agricultural exchange, divided into those from the reduction in distribution stages and from the increase in user convenience. For the analysis, benefits from the reduction in distribution stages are divided into logistics cost saving, shrinkage loss reduction, and commission reduction. Benefits from the increase in user convenience are divided into shipper's saving of search cost and buyer's saving of transaction cost. Assuming that the online agricultural exchange is worth KRW 500 billion, the expected economic benefit was analyzed to be about KRW 38.3 billion per year.
