"The Effects of Relative Prices on Trade Shares," Cowles Foundation Discussion Paper No. 597, June 1981, unpublished.Paper: pdf file
I never published this paper, but I have included it in my research list because it is the first specification of trade share equations for my multicountry econometric model. The trade share equations in this paper were used for the results in 1982#2. The specification of the trade share equations was changed for the model presented in 1984#2--see Chapter 4, Section 4.2.6, . The trade share equations are also discussed in detail in 2020#3.
