An Analysis of the Effect of the Subsidy for Closing Farms on the Number of Hanwoo Breeding Herds

This paper analyzes how the subsidy for closing farms affected the number of Hanwoo breeding herds using ARIMA model. To build a estimation model, we use a bio-behavioral system based on birth rates and slaughter rates. This study sets up three time series models to estimate and capture the effect of subsidy program for closing farms in Hanwoo industry. The main differences among three models depends on which variable of female cow slaughter rate is used. This paper compares the actual numbers and predicted estimates and calculates the effect of the sub-sidy program. To testify the statistical significance of the results, we use dummy variable in time series model s and economic models. The results show that the calf birthrate is significantly de-creased about 4 to 8 percent point by the subsidy for closing farms. However, the female cow slaughter rate is not statistically significant.
