The impact of trade promotion services on Canadian exporter performance
研究了加拿大贸易专员服务出口促进项目对出口商的影响，发现其显著提升了现有产品-目的地市场的出口额，而对拓展新产品或新市场的作用较小且不稳健。
Abstract From 1999 to 2006, Canadian firms successfully diversified their exports to destinations beyond the United States while smaller firms increased their share in total exports. Both are explicit aims of the Trade Commissioner Service export promotion program. Exploiting assumptions from the treatment effects literature, we identify a causal, export‐boosting effect. In contrast with existing evidence for Latin American countries, the intensive margin effect—higher exports to existing product‐destination markets—dominates. Effects at the extensive margin—exporting more products to more destinations—are smaller and sensitive to identification assumptions. We interpret this evidence in light of trade models with heterogeneous firms.
