Testing the Heckscher–Ohlin–Vanek theory with a natural experiment
利用西岸通勤者几乎无法进入以色列的历史事件，检验了赫克歇尔-俄林-瓦内克贸易模型的三个关键预测，发现工资变化与劳动力冲击规模无关，且劳动力回流多的地区更转向劳动密集型产业，消费数据也支持模型假设。
Abstract I use the historical episode of near‐elimination of commuting from the West Bank into Israel to test three key predictions of the Heckscher–Ohlin–Vanek model of trade and find strong support for them. On the production side, I use variation between districts and find that wage changes were not correlated with the size of the shock to the labour force (factor price insensitivity) and that districts that received larger influx of returning commuters shifted production more towards labour‐intensive industries (Rybczynski effect). On the consumption side, data are consistent with identical homothetic preferences, which, combined with the production results, supports the Heckscher–Ohlin–Vanek theorem on the factor content of trade.
