Can R&D-inducing green tariffs replace international environmental regulations?

This paper investigates the link between trade and environment by exploring the effects of green tariffs on innovation, location of production and the environment. It shows that tariffs levied on polluting goods could result in less world pollution than global harmonization of environmental standards by inducing more pollution-abatement R&D effort and generating lower unit emissions from production. Specifically, green tariffs reduce pollution by (1) shifting production to the region where environmental standards are respected, (2) inducing the firm in the clean country to engage in more abatement R&D by granting it a higher market power/share in its home market, (3) instigating green R&D investment by deterring delocation. When these outweigh the R&D-creating effect of environmental harmonization in the dirty country, green tariffs bring about a cleaner environment.     

Intellectual Property Rights and Entry into a Foreign Market: FDI versus Joint Ventures

We study the effect of the intellectual property rights (IPR) regime of a host country (South) on a multinational's decision between serving a market via greenfield foreign direct investment to avoid the exposure of its technology or a North–South joint venture (JV) with a local firm, which allows R&D spillovers under imperfect IPRs. JV is the equilibrium market structure when R&D intensity is moderate and IPRs strong. The South can gain from increased IPR protection because it encourages a JV, whereas policies to limit foreign ownership in a JV gain importance in technology‐intensive industries as complementary policies to strong IPRs.     

Political institutions and government spending behavior: theory and evidence from Iran

This study examines how the quality of political institutions affects the distribution of the government budget in Iran. We first introduce a mechanism through which democracy can shift government expenditure from national defense (military) to productivity-enhancing public spending (e.g., education). Using impulse response functions and a variance decomposition analysis on the basis of a vector autoregressive (VAR) model, our results imply that the response of military spending to an improvement (a deterioration) of democratic institutions is negative (positive) and statistically significant, whereas that of education spending is positive (negative) and significant. Our results are robust to other indicators of political institutions, different orderings of variables in the VAR, and alternative specifications of government spending categories.     

Financial Liberalization and Stock Market Efficiency: Causality Analysis of Emerging Markets

This paper studies the long- and short-run relationship between financial liberalization and stock market efficiency. It expands the extant body of knowledge by investigating Granger causality relationship applying mean group, common correlated effect mean group and common correlated effect pooled estimator to balanced panel data for 27 emerging markets over the period 1996–2011. We find evidence of financial liberalization Granger causes stock market efficiency, which is consistent with liberalization leads to efficiency hypothesis. Subsequently, our work makes a fresh contribution to the literature by focusing on informational efficiency of stock markets rather than financial development. Furthermore, we find that a negative long-term relationship between financial liberalization and stock return autocorrelation coexists with a positive short-term relationship between the two. The findings that financial liberalization, which has a deteriorated effect on stock market efficiency in the short-run, but positive impact in the long-run, allow us to draw an analogy similar to the J-curve hypothesis.     

Firm Heterogeneity,Contract Enforcement,and the Industry Dynamics of Offshoring*

We develop an endogenous growth model with R&D spillovers to study the long‐run consequences of offshoring with firm heterogeneity and incomplete contracts. In so doing, we model offshoring as the geographical fragmentation of a firm's production chain between a home upstream division and a foreign downstream division. While there is always a positive correlation between upstream bargaining weight and offshoring activities, there is an inverted U‐shaped relationship between these and growth. Whether offshoring with incomplete contracts also increases consumption depends on firm heterogeneity. As for welfare, whereas with complete contracts an R&D subsidy is enough to solve the inefficiency due to R&D spillovers, with incomplete contracts a production subsidy is also needed.     

Offshoring and product innovation

We propose an endogenous growth model with offshoring to investigate its effects on product innovation and growth in the country of origin. Offshoring is associated with reduced feedback from offshored plants to domestic labs as well as coordination problems between the offshored and domestic divisions of firms. Production and transport cost parameters affect the static decision to relocate plants but not R&D. Hence, offshoring may be chosen by firms when it damages the growth rate of their countries of origin. In particular, if offshoring reduces the feedback from plants to labs, it is likely to bring dynamic losses when the countries of origin are large, especially in sectors in which R&D is cheap and product differentiation is strong. It is also likely to slow growth in sectors in which contractual incompleteness gives a strong bargaining power to offshored divisions in intra-firm transactions.

Asymmetric Labor Markets, Southern Wages and the Location of Firms

This paper studies the behavior of firms towards weak protection of labor standards in developing countries (South). A less than perfectly elastic labor supply in the South gives firms an oligopsony position in the labor market tempting them to strategically reduce output to cut wages. In an open economy, competitors operating where labor standards are recognized meanwhile enjoy less aggressive competitors and raise output. Delocation also increases Southern wages and triggers a competition effect, lowering ex post output and hence potential profits of a relocating firm. These effects reduce relative profitability of moving production to the South casting doubts on traditional beliefs that multinationals are attracted to regions with lower wages. Moreover, adopting a minimum wage policy in the South eliminates the oligopsony distortion and improves competitiveness of Southern firms in the world product market. It also enhances consumer and wage surplus in the South and hence unambiguously raises Southern welfare.     

Strategic Intellectual Property Rights Policy and North-South Technology Transfer

This paper analyzes welfare implications of protecting intellectual property rights (IPR) in the framework of TRIPS for developing countries (South) through its impact on innovation, market structure and technology transfer. In a North-South trade environment, the South sets its IPR policy strategically to manipulate multinationals’ decisions on innovation and location. Firms can protect their technology by exporting or risk spillovers by undertaking FDI to avoid tariffs. A stringent IPR regime is always optimal for the South as it triggers technology transfer by inducing FDI in less R&D-intensive industries and stimulates innovation by pushing multinationals to deter entry in high-technology sectors.

Intellectual property rights and diaspora knowledge networks: Can patent protection generate brain gain from skilled migration?

This paper studies the mechanism through which intellectual property rights (IPR) protection can influence the impact of skilled migration on innovation activities in developing countries. We argue that knowledge acquired by emigrants abroad can flow back to their country of origin through diaspora networks. IPR protection in the sending country facilitates this channel by increasing returns to skills and encouraging workers to move into the innovation sector. An expansion of the innovation sector allows diaspora knowledge to be absorbed by a larger range of workers. Strong IPR enforcement therefore makes it more likely for brain drain to be transformed into brain gain.     

Intellectual property rights,product complexity and the organization of multinational firms

This paper studies how the intellectual property right (IPR) regime in destination countries influences the decision of firms between procurement from related parties and from independent suppliers while the latter may involve technology sharing or not. Using firm‐level data on the mode choice for each transaction and a new product complexity measure, results confirm that firms are generally reluctant to source complex goods from outside firm boundaries. However, when technology is shared, IPRs promote outsourcing of more complex goods whereas without technology sharing, IPRs promote outsourcing of less complex products that are prone to reverse engineering and simpler to imitate.
