◼ Chapter Overview

The Intent Of This Chapter Is To Provide Both An Overview Of The Subject Matter Of
International Economics And To Provide A Guide To The Organization Of The Text. It Is
Relatively Easy For An Instructor To Motivate The Study Of International Trade And
Finance. The Front Pages Of Newspapers, The Covers Of Magazines, And
The Lead Reports On Television News Broadcasts Herald The Interdependence Of The U.S.
Economy With The Rest Of The World. This Interdependence May Also Be Recognized By
Students Through Their Purchases Of Imports Of All Sorts Of Goods, Their Personal
Observations Of The Effects Of Dislocations Due To International Competition, And Their
Experience Through Travel Abroad.

The Study Of The Theory Of International Economics Generates An Understanding Of Many
Key Events That Shape Our Domestic And International Environment. In Recent History,
These Events Include The Causes And Consequences Of The Large Current Account Deficits
Of The United States; The Dramatic Appreciation Of The Dollar During The First Half Of
The 1980s Followed By Its Rapid Depreciation In The Second Half Of The 1980s; The Latin
American Debt Crisis Of The 1980s And The Mexican Crisis In Late 1994; And The
Increased Pressures For Industry Protection Against Foreign Competition Broadly Voiced In
The Late 1980s And More Vocally Espoused In The First Half Of The 1990s. More Recently,
The Financial Crisis That Began In East Asia In 1997 And Spread To Many Countries
Around The Globe And The Economic And Monetary Union In Europe Have Highlighted
The Way In Which Various National Economies Are Linked And How Important It Is For Us
To Understand These Connections. At The Same Time, Protests At Global Economic
Meetings Have Highlighted Opposition To Globalization. The Text Material Will Enable
Students
