13、ts from the NSE:,New structural economics emphasizes that countries at different levels of development have different optimal industrial structures, firm sizes, capital requirements and nature of risks, therefore, many institutions and policies should be different accordingly and have different poli

14、cy insights compared to the old structuralism and neoclassics: Financial institutions:Old structuralism: Direct government mobilization and allocation of financial resources.Neoclassics: Financial liberalization and development of modern big banks and equity marketNew structural economics: Optimal f

15、inancial structure will be different depending on level of development. For low-income countries, small, local financial institutions should be the core of financial structure; and big banks and equity market will play increasingly important role as the firm size and risks increase with the level of

16、 development.Fiscal stimulus:Old structuralism: Keynesian stimulus, using tax and expenditure policies to offset business cycles.Neoclassics: Ricardian Equivalence, warming against the use of fiscal stimulus.New Structural economics: Beyond Keynesianism, using public investments to invest in product

18、process of continuous process of industrial upgrading and structural transformation. The state should play a facilitating role in the process.Industrial policy is a necessary instrument for the state to play the facilitating role Contents of coordination will be different, depending on industries. T

19、he governments resources and capacity are limited. The government needs to use them strategically.The sad fact is that most governments in the developing world used industrial policies but failed, the reason was:Attempt to develop industries that went against comparative advantageThe firms in the in

20、dustrial policys targeted sectors were non-viable in competitive markets and required government policy supports for their initial investment and continuous operations. The supports were implemented through price distortions. As a result, planning and administrative allocations were required.This le

22、ns The issues are:The government may not have the capacity to introduce all those changesThe first-best institutions may be different at different stage of developmentNo identification of industries with latent comparative advantages and no compensation for the first moversGrowth DiagnosticsThe goal

23、 is to remove binding constraintsThe issues are:Binding constraints are endogenous to industriesIt relies on survey of existing firms. Many of them may be in industries where the country has no comparative advantages.No firms will be in the new industries that the countries have latent comparative a

24、dvantageAim before fire: For an industrial policy to be successful, it should target sectors that conform to the economys latent comparative advantage:Firms will be viable and the sectors will be competitive once the government helps the firms overcome the coordination and externality issuesBut how

25、to pick the sectors that are the economys latent comparative advantages,19,A,The existing approaches for in,What Can Be Learned From History,Historical experiences show that successful countries industrial policies, in general, targeted dynamic industries in successful countries with a similar endow

26、ment structure and somewhat higher per capita income:Britain targeted the Netherlands industries in the 16th and 17th century, its per capita GDP was about 70 % of Netherlands.Germany, France, and USA targeted Britains industries in the late 19th century, their per capita income were about 60 to 75

27、% of Britains per capita GDPIn Meiji restoration, Japan targeted Prussias industries, its per capita GDP was about 40% of Prussias. In the 1960s, Japan targeted USAs industries, its per capita GDP was about 40% of USAs per capita GDPIn the 1960s-1980s, Korea, Taiwan, Hong Kong, and Singapore targete

28、d Japans industries, their per capita income was about 30% of Japans per capita GDPIn the 1970s, Mauritius targeted Hong Kongs industries, its per capita income was about 50% of Hong Kongs.In the 1980s, Ireland targeted information industries, its per capita income was about 45% of the USAs.In the 1

29、990s, Costa Rica targeted memory chip assembly and testing, its per capita GDP was about 40% of that of Taiwan, which was the main economy in this sector. Unsuccessful industrial policies in general target industries in countries where their per capita GDPs were less than 20 per cent of those target

30、ed countries.A new approach for industrial policy: Growth identification and facilitation,20,A,What Can Be Learned From Histo,Step 1: Identifying sectors with latent comparative advantage,Find dynamic growing countries with a similar endowment structure and with about 100% higher per capita income.

31、Identify tradable industries that have grown well in those countries for the last 20 years as the potential targets of industries for upgrading or diversificationSimilar to Hausmanns idea of jumping to nearby trees, but easier to implementConsistent with FDI research suggesting technology transfer i

32、s easier when domestic and foreign firms are closer to each other on the technological frontier (Blomstrom, Kokko),21,A,Step 1: Identifying sectors wi,Step 2: Removing constraints for existing firms.How?,See if some private domestic firms are already in those industries (of which may be existing or

33、nascent). Identify constraints to quality upgrading, further firm entry, and reduction of transaction costs (hard and soft infrastructure). Take action to remove constraintsMethods:Value-chain analysisGrowth Diagnostics (Hausmann, Rodrik, and Velasco (2008)Investment Climate Assessments (World Bank)

34、Successful ExamplesChile: wineEcuador: cut flowers,22,A,Step 2: Removing constraints f,Step 3: Seek FDI or organize New Firm Incubation Programs,In industries where no domestic firms are currently present, seek FDI from countries examined in step 1, or organize new firm incubation programs.Famous ex

35、amples of FDI:garment sector in BangladeshTextile industry in MauritiusMemory chip assembly and testing in Costa RicaElectronics and other consumer products in ChinaInformation industries in IrelandLaura Alfaro and Andrew Charlton, in a paper in the Journal of International Economics, show that:Many

36、 countries promote FDI selectivelyTargeted sectors grow fasterFamous example of incubation programs:Taiwan-Chinas Hsingchu Science-based Industrial Park for the development of electronic and IT industriesFundacin Chiles demonstration of commercial salmon farming,23,A,Step 3: Seek FDI or organize N,S

37、tep 4: Scale up private firms self discovery,In addition to the industries identified above, the government should also pay attention to spontaneous self discovery by private enterprises and give support to scale up the successful private innovations in new industriesExamplesIndias information indus

39、 these barriers to firm entry and FDI and encourage industrial clusters.Examples:Chinas special economic zonesMauritius export process zoneEnormous Increase in Number of Zones World Wide: from 29 in 1975 to 3500 in 2006!The zones will be successful only if the industries targeted by the zones are co

41、governments in developed countries compensate pioneer firms by:PatentsSupports for basic researchMandateGovernment procurementExcept for patents, the other supports are sector specificThe government in a developing country can compensate pioneer firms in the listed identified in step 1 withTax incentives for a limited periodDirect credits for investmentsAccess to foreign exchangesAs the governments support is only to compensate for information externalities, the support can, and should, be limited both in magnitude and time.,26,A,Step 6: Provide limited subsid,
