Prices, Activity, and Machinery Exports: An Analysis Based on New Price Data
利用美国、德国和日本的新出口价格数据，分析机械和运输设备出口的价格弹性，发现美国弹性最高、德国最低，且价格变化对出口的影响持续至少两年，美国可能长达四年。
New data for the export prices of the United States, Germany, and Japan produced price elasticities for exports of machinery and transport equipment that were highest for the United States and lowest (well below 1) for Germany. The effects of price changes on exports lasted at least two years in all three countries and possibly four years in the United States. Only in Germany would most effects of price changes take place in the year of the change. U.S. export income in foreign currency would not exceed its pre-depreciation level until the third year after a depreciation.
