technology make the private return to investing in these activities less than their social return. This means
that the private sector will tend to invest less in high-technology sectors than is socially optimal. Although
there may be some case for intervention, the difficulties in targeting the correct industry and understanding
the quantitative size of the externality make effective intervention complicated. To address this market
failure of insufficient knowledge creation, the first best policy may be to directly support research and
development in all industries. Still, although it is a judgment call, the technology spillover case for
industrial policy probably has better footing in solid economics than any other argument.
Another set of market failures arises when imperfect competition exists. Strategic trade policy by a government
can work to deter investment and production by foreign firms and raise the profits of domestic firms.
An example is provided in the text that illustrates the case where the increase in profits following the
imposition of a subsidy can actually exceed the cost of a subsidy to an imperfectly competitive industry
if domestic firms can capture profits from foreign firms. Although this is a valid theoretical argument for
strategic policy, it is nonetheless open to criticism in choosing the industries that should be subsidized and
the levels of subsidies to these industries. These criticisms are associated with the practical aspects of
insufficient information and the threat of foreign retaliation. The case study on the attempts to promote the
semiconductor chips industry shows that neither excess returns nor knowledge spillovers necessarily
materialize even in industries that seem perfect for activist trade policy.
The next section of the chapter examines the anti-globalization movement. In particular, it examines the
concerns over low wages in poor countries. Standard analysis suggests that trade should help poor
countries and, in particular, help the abundant factor (labor) in those countries. Protests in Seattle, which
shut down WTO negotiations, and subsequent demonstrations at other meetings showed, though, that
protestors either did not understand or did not agree with this analysis.
The concern over low wages in poor countries is a revision of arguments in Chapter 2. Analysis in the
current chapter shows again that trade should help the purchasing power of all workers and that if anyone
is hurt, it is the workers in labor-scarce countries. The low wages in export sectors of poor countries
are higher than they would be without the export-oriented manufacturing, and although the situation of
these workers may be more visible than before, that does not make it worse. Practically, the policy issue is
whether or not labor standards should be part of trade pacts. Although such standards may act in ways
similar to a domestic minimum wage, developing countries fear that such standards would be used as a
protectionist tool. A case study on the 2013 collapse of a garment factory in Bangladesh highlights this
tension. The Bangladeshi garment industry would not be globally competitive if it had to raise labor
standards to rich country standards. Bangladeshi garment workers, though very poorly paid by rich
country standards, earn more than workers in non-export sectors. A potential solution would be for
consumers in rich countries to pay more for goods certified to have been produced under improved labor
standards, thereby giving producers in poor countries both the means and the incentive to improve labor
standards,
Anti-globalization protestors were by no means united in their cause. There were also strong concerns that
export manufacturing in developing countries was bad for the environment. Again, the issue is whether these
concerns should be addressed by tying environmental standards into trade negotiations, and the open
question is whether this can be done without destroying the export industries in developing countries.
