Would global patent protection be too weak without international coordination?

I extend the Grossman and Lai (2004) model to answer the question, "Would global patent protection be too weak without international coordination?" by introducing firmbiased government preferences and trade barriers in the model. I make use of the estimates of the firm-bias parameter from the political economy literature to proxy for the degree of governments' firm-bias. Then I calculate the range of trade barriers that is sufficient to give rise to under-protection of patents in the global system without international policy coordination in IPR protection. I make the judgement that the true trade barrier between countries very likely falls within this range of under-protection. Therefore, I conclude that there was probably under-protection of patents without international policy coordination in IPR protection. It means that the free-rider problem with a large number of independent players overrides the effects of firm-bias and trade barriers, giving rise to too low a rate of innovation in the world. Allowing for the possibility that countries discriminate against foreign firms in Nash equilibrium does not change this conclusion. The problem can possibly be corrected by international coordination in intellectual property rights (IPR) protection.Intellectual property rights, TRIPS, Innovation

The most-favored nation rule in club enlargement negotiation

We study the effects of the Most-Favored Nation rule in an applicant's negotiation to join a club. When the applicant has to carry out a series of bilateral bargains with the existing members, we find that there are two effects of the MFN rule, viz. the hardened bargainer effect and the free-rider effect. The former effect tends to favor the applicant, while the latter effect tends to hurt the applicant. We find that the free-rider effect is stronger the more asymmetric are the members. The hardened bargainer effect is stronger the larger is the "size of the pie." As the number of members increase, it is more likely that the hardened bargainer effect would dominate.International trade ; Industrial organization (Economic theory) ; World Trade Organization

A Theory of Government Procrastination

We present a theory to explain government procrastination as a consequence of its present-bias resulting from the political uncertainty in a two-party political system. We show that under a two-party political system the party in office tends to be present-biased. This may lead to inefficient procrastination of socially beneficial policies that carry upfront costs but yield long-term benefits. However, procrastination is often not indefinite even as we consider an infinite-horizon game. There exist equilibria in which the policy is implemented, and in many cases carried out to completion in finite time. When the net social benefit is large, there is no procrastination problem. When the net social benefit is small, the policy can be procrastinated indefinitely, though there may co-exist some gradual implementation equilibria. When the net social benefit is intermediate in magnitude, there are all sorts of procrastination equilibria, including gradual implementation. The theory predicts that a government with a more strongly predominant party tends to procrastinate less.present-bias, procrastination, policy implementation

International Protection of Intellectual Property

We study the incentives that governments have to protect intellectual property in a trading world economy. We consider a world economy with ongoing innovation in two countries that differ in market size, in their capacities for innovation, and in their absolute and comparative advantage in manufacturing. We associate the strength of IPR protection with the duration of a country's patents that are applied with national treatment. After describing the determination of national policies in a non-cooperative regime of patent protection, we ask, Why are patents longer in the North? We also study international patent agreements by deriving the properties of an efficient global regime of patent protection and asking whether harmonization of patent policies is necessary or sufficient for global efficiency.

Would Global Patent Protection be too Weak without International Coordination?

This paper analyzes the setting of national patent policies in the global economy. In the standard model with free trade and social-welfare-maximizing governments à la Grossman and Lai (2004), cross-border positive policy externalities induce individual countries to select patent strengths that are weaker than is optimal from a global perspective. The paper introduces three new features to the analysis: trade barriers, firm heterogeneity in terms of productivity and political economy considerations in setting patent policies. The first two features (trade barriers interacting with firm heterogeneity) tend to reduce the size of cross-border externalities in patent protection and therefore make national IPR policies closer to the global optimum. With firm lobbying creating profit-bias of the government, it is even possible that the equilibrium strength of global patent protection is greater than the globally efficient level. Thus, the question of under-protection or not is an empirical one. Based on calibration exercises, we find that there would be global under-protection of patent rights when there is no international policy coordination. Furthermore, requiring all countries to harmonize their patent standards with the equilibrium standard of the most innovative country (the US) does not lead to global over-protection of patent rights.intellectual property rights, patents, TRIPS, harmonization

Accession Rules and Trade Agreements: The Case of the WTO

This paper models the accession process to the World Trade Organization (WTO) as a two stage game. In the first stage, member countries choose tariff rates to be applied on trade with each other. In the second stage a non-member country applies for membership in the agreement and negotiates with the member countries over the tariff rates to be applied. Based on the rules of the WTO accession process, we model this negotiation using the Nash bargaining solution. The analysis focuses on the question of how the pattern of trade between the acceding country and the member countries affects the distribution of gains from accession between the members and the acceding countries, given the rules of the WTO negotiation process. We consider two n good, n country trade models which highlight features of the WTO tariff negotiations. The first is a model in which each country imports one good from all of the other countries (competing supplier model). This model highlights the role of the MFN principle, since member countries are forced to extend the same tariff treatment to non-members when they join. We show that the non-member will free ride on tariff reductions among the member countries in this case, and that the non-member will gain a larger fraction of the gains from accession if transport costs are sufficiently low. The second model considers a case in which each country exports a single good to the other countries (principal supplier model). We show that in this case tariff reductions by the member countries reduce the welfare of the non-member country, and the member countries gain a larger share of the gains from accession.

A Model of Trade with Ricardian Comparative Advantage and Intra-sectoral Firm Heterogeneity

In this paper, we merge the heterogenous firm trade model of Melitz (2003) with the Ricardian model of Dornbusch, Fisher and Samuelson (DFS 1977) to explain how the pattern of international specialization and trade is determined by the interaction of comparative advantage, economies of scale, country sizes and trade barriers. The model is able to capture the existence of inter-industry trade and intra-industry trade in a single unified framework. It explains how trade openness affects the pattern of international specialization and trade. It generalizes Melitz’s firm selection effect in the face of trade liberalization to a setting where the patterns of inter-industry trade and intra-industry are endogenous. Although opening to trade is unambiguously welfare-improving in both countries, trade liberalization can lead to an counter-Melitz effect in the larger country if it is insufficiently competitive in the sectors where it has the strongest comparative disadvantage but still produces. In this case, the operating productivity cutoff is lowered while the exporting cutoff increases in the face of trade liberalization. This is because the intersectoral resource allocation (IRA) effect dominates the Melitz effect in these sectors. Consequently, the larger country can lose from trade liberalization. Some hypotheses related to firms’ exporting behavior across sectors upon opening up to trade and upon trade liberalization are also derived. Analyses of firm-level data of Chinese manufacturing sectors confirm these hypotheses.inter-industry trade, intra-industry trade, heterogeneous firms, trade liberalization
