What is an accurate description of how the political economy of many of the world's nation-states has changed radically since the late 1980s?

The most important facts of the economy were: the imbalances of countries such as the United States, Japan and Germany, which were manifested in the exchange, credit and securities markets, the acceleration in the integration of Europe.

Explanation:

These facts suggest that the economic policy of the late 1980s could focus more on the subsidiary and market economy, with better coordination and that it would be more favored in saving and thinking about the stability of the financial and banking system. The most important challenge should be to converge towards GDP or the level of inflation without resorting to monetary policy and without abuse in fiscal policy.
