Investment, Wage Goods, and Industrial Policy
Raising and sustaining long-run growth rates is made more difficult by the complexity of economic growth and by the complexity of growth theory debates. Nonetheless, the investment rate is central to long-run growth and development. Growth sustained by high investment rates will also involve structural change: a shift of resources into high-productivity economic activities. This chapter combines discussion of investment—why it matters, what economic policies help to raise investment rates and keep them high—with discussion of ‘industrial policy’. But the terrain of industrial policy has expanded to take account of new high-productivity activities, of servicification, and of agribusiness; policy officials thus need to refine the criteria used to make resource allocation and incentive decisions accordingly. A particularly important political economy constraint on investment rates is the non-inflationary supply of wage goods.
