演講摘要 : We reconcile the conflicting evidence between the aggregate and the microeconomic data on the exchange rate elasticity of exports. The estimation of typical macroeconomic export equations provides us with insignificant estimates for this elasticity, while recent firm level evidence suggests significantly negative values. Using Japanese firm data, we estimate a monopolistic competition model of exporting firms, and show that the exchange rate elasticity of exports is significantly negative at both firm and aggregate levels, with consistent aggregation. We identify the preferences and technology parameters and find the importance of decreasing returns to scale and the high elasticity of substitution among consumption goods in determining the magnitude of this elasticity.
