Against the background of an ongoing trade dispute between the United States and China, Senior Scholar Jan Kregel analyzes the potential for achieving international adjustment without producing a negative impact on national and global growth. Once the structure of trade in the current international system is understood (with its global production chains and large imbalances financed by international borrowing and lending), it is clear that national strategies focused on tariff adjustment to reduce bilateral imbalances will not succeed. This understanding of the evolution of the structure of trade and international finance should also inform our view of how to design a new international financial system capable of dealing with increasingly large international trade imbalances.

Empirical Studies

In this second part of our study we survey the rapidly expanding empirical literature on the determinants of the functional distribution of income. Three major strands emerge: technological change, international trade, and financialization. All contribute to the fluctuations of the labor share, and there is a significant amount of self-reinforcement among these factors. For the case of the United States, it seems that the factors listed above are by order of increasing importance. We conclude by noting that the falling US wage shares cointegrates with rising inequality and a rising top 1 percent income share. Thus, all measures of income distribution provide the same picture. Liberalization and financialization worsen economic inequality by raising top incomes, unless institutions are strongly redistributive.

The labor share has also fallen, for structural reasons and for reasons related to economic policy. Such explanations are left to parts III and IV of our study, respectively. Part I investigated the theories of income distribution.
