タイトル(掲載誌)Discussion Papers In Economics And Business
一般注記We develop a small open economy model with non-renewable natural resource, where firms can improve the extraction technology by investment. We analytically derive the equilibrium investment in extraction technology and then derive the equilibrium duration of non-renewable resource extraction. We show that a subsidy for investment in extraction technology promotes the investment and extends the duration. Moreover, we assume that the subsidy is financed by the income tax, and examine the effect of the investment subsidy. As a result, the higher the share of natural resource earnings in total output, the weaker the positive effect of subsidy on the duration is. The optimal subsidy which maximizes the profit from natural resource sales is lower as the ratio of resource sales to non-resource output is higher.
