| Outline of Final Research Achievements |
There are some facts commonly observed in the real trading world. First, many countries trade in a large number of goods. Second, there exist some products (link commodities in technical terms) that are commonly produced in more than one country and exported: for example, cars in Japan, USA, and Germany; beef in Brazil, USA, and Australia. Third, most countries engaged in foreign trade have involuntary unemployment, or Keynesian unemployment, arising from a shortage of effective demand. Although there are the other facts such as the existence of inputs trade, this study developed and provided a trade model that incorporated the above three facts.

| Academic Significance and Societal Importance of the Research Achievements |
研究成果の概要で述べたような3つの事実（多数国多数財貿易、連結財、ケインズ的失業）を同時に組み込んだ貿易モデルは、これまで内外ともに存在していなかった。本研究において初めて開発・提示されたものであり、学術的な意義がある。さらに、外国と競合する部門の技術進歩はその国の交易条件を有利にするが、自国だけが競争力を持つ部門の技術進歩はそうではないことを示した。これは、国内厚生水準を上昇させるための政策的優先順位を考える上で有意義である。
