France，in addition to its occasional stabs at strategic trade policy，pursues an active nationalist cultural policy，promoting French art，music，fashion，cuisine，and so on．This may be primarily a matter of attempting to preserve a national identity in an increasingly homogeneous world，but some French officials also defend this policy on economic grounds．In what sense could some features of such a policy be defended as a kind of strategic trade policy？

If the United States had its way，it would demand that Japan spend more money on basic research in science and less on applied research into industrial applications．Explain why in terms of the analysis of appropriability．

Suppose the U.S. government were able to determine which industries will grow most rapidly over the next 20 years．Why doesn't this automatically mean that the nation should have a policy of supporting these industries' growth？

The U.S. Commerce Department has urged that the United States provide special support for its high-technology industries．It argues that these industries have the prospect of rapid future growth，provide inputs to many other industries．and generate technology that benefits the whole economy．Furthermore．some U.S. high-technology industries such as aircraft and microelectronics face challenges by government-supported foreign competitors．Which of these arguments might be valid reasons for the United States to have a policy targeting these industries？

“The new strategic trade policy argument demonstrates the wisdom of policies like that of South Korea，which subsidizes its exports across the board．The subsidy gives each industry the strategic advantage it needs to establish itself in world competition”Discuss．
