Suppose that you test the Linder hypothesis by comparing Germany's absolute difference in per capita income from each of its trading partners with the size of Germany's total trade with each respective partner. You find a strongly negative correlation. Do you thus conclude that the Linder hypothesis must necessarily offer a good explanation of Germany's trade? Why or why not?

The strongly negative correlation between Germany's absolute difference in per capita income from its trading partners and the size of Germany's total trade with each partner does not necessarily mean that the Linder hypothesis offers a good explanation of Germany's trade. While the Linder hypothesis suggests that countries with similar income levels are more likely to trade with each other due to similar preferences and demand for goods, the negative correlation could be influenced by other factors such as trade policies, geographical proximity, or historical ties.

It is important to consider other variables and conduct further analysis before concluding that the Linder hypothesis is a good explanation for Germany's trade patterns. Additionally, the Linder hypothesis is just one of many theories that attempt to explain international trade patterns, and it is important to consider other theories and factors that may also influence Germany's trade relationships with its partners.

Suppose that data are assembled on (1) research and development expenditures as a fraction of industry costs across U.S. industries (ranked from highest to lowest), and (2) the export success of U.S. industries (ranked from highest to lowest). If the "product cycle theory" is useful as an explanation for the pattern of U.S. exports, then an analyst would expect that statistical association (rank correlation coefficient) between these two series of data would be
