Multinational public goods provision under multilateral income transfers and productivity differences

摘要

This article examines multinational public goods provision under multilateral income transfers and productivity differences across countries. Under a planner who uses linear approximation for utility maximization, we show that (1) a country is an income receiver if it has a higher productivity than the average in producing public goods, enabling it to provide more public goods; (2) the amount of transfers can be pinned down for all countries with an adjustment cost; (3) each country obtains an identical utility increment; and (4) the country with the lowest adjustment cost is the best candidate for the planner country. All results are derived based on well-known information regarding the cost of producing the public goods and income levels.
