The Conundrum of Recovery Policies: Growth or Jobs?

This paper adopts a Neo-Schumpeterian approach to macroeconomics, by proposing a model which includes fully-endogenous growth, involuntary search-based unemployment, and financial frictions. The model analyzes the effects of several recovery policies used by governments to fight unemployment or/and enhance growth. Employment protection legislation reduces growth and unemployment. Policies that reduce the cost of job vacancies decrease unemployment and raise growth. Industrial policies in the form of production subsidies to young small firms, production taxes to adult large firms, and R&D subsidies increase growth and unemployment. Policies that reduce financial frictions accelerate growth but exert an ambiguous effect on unemployment.fully- endogenous growth, Schumpeterian unemployment, financial frictions, recovery policies, vacancy creation

Product innovation, diffusion and endogenous growth

We develop a model of Schumpeterian growth featuring a stochastic diffusion process where the rate of commercial success of product innovations is endogenously determined by advertising intensity. We consider both informative advertising, which young technological leaders use to increase the probability of diffusion, and defensive advertising, which incumbents use to prevent the diffusion of competing products. Economic growth depends positively on the arrival rate of product innovations and the diffusion rate of innovations into the mainstream market. We show that R&D subsidies shift relative investment incentives towards innovation and away from diffusion. This creates an inverted U-shaped relationship between R&D subsidies and both economic growth and welfare as innovations arrive more frequently, but fewer commercialize successfully. We find that lower advertising costs increase diffusion, growth, and welfare when advertising is purely informative. When we include defensive advertising, lower costs lead to socially wasteful increases in resources devoted to advertising without large increases in diffusion, reducing growth and welfare

Intellectual Property-Related Preferential Trade Agreements and Offshoring to Developing Countries

International standards in the protection of intellectual property rights (IPRs) are increasingly guided by bilateral and regional preferential trade agreements (PTAs). In this paper, we estimate the effect of these IP-related PTAs on US offshoring behavior in developing countries. We utilize a difference-in-difference empirical methodology that addresses several possible sources of endogeneity and exploits industry variation in the importance of IPRs to identify the effect of these PTA-induced IPR reforms. We find that IP-related PTAs are associated with a substantial increase in US offshoring in IPR-intensive industries relative to non-IPR-intensive industries. This increase occurs both within the boundaries of the multinational firm and through arm’s-length contracts with domestic firms. We do not find strong evidence for a compositional shift towards either type of offshoring. These findings provide direct empirical evidence that PTA-induced IPR reform stimulates multinational activity in developing countries

R&D policies, endogenous growth and scale effects

This paper constructs a scale-free endogenous growth model and studies the determinants of optimal R&D policy. The model combines two of the main approaches to removal of scale effects: the rent protection approach and the diminishing technological opportunities approach. The steady-state rate of innovation is a function of all of the model's parameters including the R&D subsidy/tax rate. Thus, growth is fully endogenous. Numerical simulations imply that it is optimal to tax R&D when innovations are of very small and very large magnitudes, and to subsidize R&D when innovations are of medium size. Under a wide range of empirically relevant calibrations, the subsidy rate turns out to be positive and fluctuates between 5% and 25%.Scale effects Innovation Rent protection Technological change

A Schumpeterian model of equilibrium unemployment and labor turnover

This paper constructs a general equilibrium model of equilibrium unemployment by combining an endogenous growth model with a variant of equilibrium search theory. The analysis offers two explanations for the causes of widening wage gap between skilled and less-skilled labor, and rising unemployment rate among the less skilled: technological change in the form of an increase in the size of innovations or skilled labor saving technological change in R&D activity. In addition, the model identifies two distinct effects of faster technological progress on the aggregate unemployment rate. First, it increases the rate of labor turnover and therefore increases the aggregate unemployment rate - the creative destruction effect. Second, it creates R&D jobs, which offer workers complete job security, and consequently reduces the aggregate unemployment rate - the resource reallocation effect.Frictional unemployment - Wage inequality - Endogenous growth - Job-matching

Globalization, R&D and the iPod Cycle

This paper constructs a dynamic scale-free North-South model of trade with endogenous innovation. In the North a local-sourcing-targeted race and an outsourcing-targeted R&D race take place simultaneously within each industry. The former results in the winner firm manufacturing in the North, while the latter culminates in the winner firm's immediate outsourcing to the South, generating the iPod cycle. We study three aspects of globalization: reductions in the resource-requirement in outsourcing-targeted R&D, increased subsidies to outsourced production, and reduced Southern imitation due to TRIPs. Each event boosts outsourcing-targeted R&D and increases the frequency of iPod cycles. The aggregate innovation rate rises despite a possible fall in local-sourcing-targeted R&D, and the North-South relative wage decreases.Outsourcing Innovation Product cycle Endogenous growth

Globalization, rent protection institutions, and going alone in freeing trade

We construct a two-country North South Product-cycle model of trade with endogenous growth and trade barriers. We remove the scale effects on growth by incorporating rent protection activities by Northern incumbents. We examine the effects of two forms of globalization an expansion of the relative size of the South and unilateral trade liberalization by either country. We find that the location of rent protection institutions and the sectoral trade structure determine whether or not globalization raises steady-state economic growth. We demonstrate that for accelerating worldwide economic growth, contrary to conventional wisdom, unilateral Northern trade liberalization is preferable to bilateral trade liberalization
