This paper documents that antidumping (AD) "echoing" (i.e., different countries sequentially imposing AD measures on the same product from the same exporter) is common practice among users of AD. We develop a dynamic game where two competing importers can impose AD measures on a third exporting country in one of two periods, if at all. Assuming that governments are politically motivated (favoring their import-competing industry), AD echoing occurs only for intermediate values of a country's political-economy parameter. This result is confirmed by our econometric analysis, demonstrating that countries' political-economy-driven AD actions are interdependent and should not be analyzed in isolation.
