Explaining service-price differences in international comparisons
用一个包含非贸易部门的一般贸易模型，重新考察各国服务价格差异及其与人均GDP的正相关关系，发现要素禀赋、人口、贸易政策和贸易差额对服务价格和实际收入有不确定甚至相反的影响。
This paper reexamines observed international differences in the price of services and the positive correlation of these with per capita GDP differences. Using a general trade model with a nontraced sector, the authors find that differences in countries' factor endowments, populations, trade policies, and trade balances will have ambiguous and sometimes opposite effects on their service prices and real incomes. Estimating the service-price equation using recent data suggests that larger endowments of agricultural land, minerals, and capital, larger trade deficits, and higher prices for tradables increase service prices. Conversely, larger populations and labor forces reduce service prices. Copyright 1991 by American Economic Association.
