Description:
In this paper we provide new empirical evidence on the relationship between market power, as measured by market share, and incomplete exchange rate pass-through. The role of market power is examined in the context of a Cournot model, which is estimated with data relating to Japan's presence in the US market. To test for the existence of possible aggregation biases due to sectoral heterogeneity, estimations are carried out on time series data for the total economy and the manufacturing sector and on panel data for five manufacturing industries at the three-digit level of classification, using the Johansen multivariate cointegration technique and the recently developed by [Larsson, R., Lyhagen, J., & Lothgren, M. (2001). Likelihood-based cointegration tests in heterogeneous panels. Econometrics Journal, 4, 109-142] multivariate panel cointegration technique. Hypotheses about the degree of pass-through are tested as restrictions on estimated equilibrium pricing equations and robustness tests are performed. The empirical results indicate that Japanese firms have market power and this validates the use of an imperfect competition model. However, it appears that market power is not the only element on which to base the analysis of the incomplete exchange rate pass-through by Japanese firms.
