Exploring Dynamics of PRODYs with International Trade Data

Tieju Ma
Abstract—Economists have used the concept of PRODYs to evaluate the added values to different traded products. Are PRODYs of products relatively constant or keeping changing? Little work has been done to answer this question. This study uses the International Trade Data from 1984 to 2010 to explore the dynamics of PRODYs. For a product, its PRODY is usually calculated as the weighted GDP per capital of countries who export the product. With the increase of most countries GDPs per capital, PRODYs of most products tends to increase. We created the PRODY-order data set for every year from 1984 to 2010, and found different dynamic patterns. Some products’ PRODY-orders tend to increase and some tend to decrease. This study implies when doing international comparisons, people should be careful that products’ relative PRODYs (PRODY-orders) could be changing.
