    Prob 1 14. In August 2007, a sharp downturn in the U.S. housing market reduced the income of many who worked in the home construction industry.

With this information, use one of the principles of economy-wide interaction to trace a chain of links that explains how reduced spending for U.S. home purchases is likely to affect the performance of the Mexican economy.
