〈The Politics of Free Trade Agreements〉 by Elhanan Helpman & Gene Grossman

[Abstract]

Suppose that an opportunity arises for two countries to negotiate a free
trade agreement (FTA). Will an FTA between these countries be politically
viable? And if so, what form will it take? We address these questions using a
political-economy framework that emphasizes the interaction between industry
special interest groups and an incumbent government. We describe the economic
conditions necessary for an FTA to be an equilibrium outcome, both for the
case when the agreement must cover all bilateral trade and when a few,
politically sensitive sectors can be excluded from the agreement.

〈Technology, Trade, and Factor Prices〉 by Paul Krugman

[Abstract]

A number of recent studies appear to show that international trade is a
secondary factor in the growing inequality of wages, with technology probably
the main culprit. These studies have, however, been subjected to severe and
in some cases harshly worded criticism by trade theorists, who argue that the
authors of these studies have misspecified the impacts of both technology and
trade on factor prices. This paper shows that it is the critics who are
confused. In particular, much recent discussion about technology, trade, and
wages is marked by a failure to distinguish between the models we all use and
the particular thought experiments we typically use to teach these models --
which happen not to be the appropriate thought experiments we need to analyze
the real-world issues.

〈Trade and Wages, Reconsidered〉 by Paul Krugman

陳博志提到的文章，基本上就是對上篇文章的再思考

8,90 年代貿易領域著名三 man，沒修過貿論的可以順便認識一下

又看到光拿本《一課經濟學》就來包山包海做政策評論的
如果你的醫生說他都不是靠新英格蘭醫學期刊，而是健康小百科這類讀物來充實醫學知識
你敢給他醫嗎？

入門書不是不好，易上手的代價就在知識有限
更別說貿論教科書本身也會談最適關稅
比如針對國外獨占廠商，本國政府可以透過課稅來提升福利的狀況

對現實的社會情況如何，大師們意見都未必一致了
又怎能妄想光靠本入門書來當政策指引？
