Trade policy becomes increasingly critical for Japan in the interdependent world with uncertainty on global trade liberalization. In spite of the gains from trade supported unanimously by economists, the opinions on trade policy widely vary among individuals, depending on income, skill, industry, and many other social backgrounds. This research project empirically explores how various individual characteristics are related with trade policy preferences in Japan. Findings from our survey on the aging population in Japan will reveal regularities informative for policy planners not only in Japan but also in many other developed economies.
