다국어 초록 (Multilingual Abstract)

This study is to analyze asymmetric spatial price transmission of Potato in Ecuador, using nonlinear autoregressive distributed lag(NARDL) model. For spatial market data, the monthly price data was collected from the System of Agriculture Public Information in Ecuador. The data of 4 regional markets are collected from January 2013 to June 2019. Based on the highest production areas, Latacunga, Quito, Riobamba and San Gabriel are selected for an analysis. For cointegration test, we made a pair of two regions such as Quito and Latacunga, Riobamba and Latacunga, San Gabriel and Latacunga, Riobamba and Quito, San Gabriel and Quito, Riobamba and San Gabriel. The null hypothesis of no co-integration is rejected at 1% and 5% significance level, respectively. Therefore, there exist long-run relationships between regional markets under the asymmetry assumption. Long-run and short-run effects of regional markets are different.
