Withdrawal of anti-dumping complaints in the EU: A sign of collusion

The study looks at a possible relation between the withdrawals of anti-dumping (AD) complaints and the price increases and quantity decreases in the EU imports. Such a positive relationship is a sign of a tacit collusion. Terminated cases without withdrawals are taken as a benchmark in the second part of the analysis. The dataset covered the ordinary new investigations only to eliminate the impact of different AD protection measures and different types of investigations. The coefficients were estimated with cross-case time-series feasible GLS regressions with heteroscedastic case time series and case-specific autocorrelation AR(1). Current and lagged nominal exchange rates were used as control variables. The collusive impact both on prices (proxied by unit values) and quantities (volumes) was detected.
