4. The U.S. economy moves into a severe recession.

5. The United States engages in a high-interest-rate monetary policy.

6. Mexican products become more fashionable to U.S. consumers.

7. The Mexican government encourages U.S. firms to invest in Mexican oil fields.

8. The rate of productivity growth in the United States diminishes sharply.
