Abstract：

Using a unique institutional setting of dual exchange rates in China, this paper provides novel evidence that firms manipulate international trade data to evade capital controls for foreign exchange arbitrage. We develop a model showing that trade data overreporting is positively (negatively) correlated with the exchange rate spread when the spread is positive (negative) if firms fake trade data to engage in foreign exchange arbitrage, and such correlations are more pronounced for products with a low risk of being detected. Empirical results from threshold regressions using the aggregate time series data and Benford's law using the disaggregated firm-product trade data between the Chinese Mainland and Hong Kong support the theoretical predictions of dual exchange rate arbitrage camouflaged under international trade. Our results highlight the challenges to implementing capital controls and may help improve the effectiveness of such policies.
