Economic Impacts of Climate Change on Korean Livestock Industry

Adopting the Ricardian approach, this study investigates the economic effects of climate changes such as average temperature and rainfalls on Korean livestock farm revenue. The explanatory variables of empirical model were selected based on the previous literature. The pseudo-panel analysis is employed to resolve the imperfectness of the panel data. The results indicate that the control variables such as farming experience, household size, employment, ownership of heavy machinery, technology use, full-time farming and male owner affect the livestock farm revenue positively, and the age does negatively. The impact of summer average temperature on farm revenue was significant and negative, while that of winter was significant and positive. The marginal change of the summer temperature decrease farm revenue per head by 2.48%. This paper suggests that the livestock farm’s revenue responds sensitively to changes in summer and winter average temperature, and so we need to establish the long-term countermeasures against rapid climate change.
