Endogenous Imitation and Technology Absorption in a Model of North–South Trade

Abstract

This paper considers the transfer of technology from the North to the South that occurs through trade in high-technology goods and explicitly models the ‘reverse-engineering’ process that allows the South to assimilate new technologies. A key finding of this study is that the South's rate of growth is dictated by the size of the country's human capital, which determines its absorptive capacity and its ability to assimilate knowledge from the North. We find that while a Southern country that is poor in human capital can only imitate, Southern countries that possess sufficiently large human capital endowments, beyond a certain threshold, signal the onset of innovation. We also find that the North enjoys a higher rate of innovation and growth with trade than without. North's gains are the highest when it trades with a human-capital ‘poor’ South, because imitation increases South's demand for Northern intermediates. But trade with the Southern countries that are human capital rich (and therefore involved in innovation), dampens their demand for Northern imports, adversely affecting North's growth. The model predicts growth convergence between the North and a South that is well passed the threshold for innovation.     

Stable International Environmental Agreements: An Analytical Approach

In this paper we examine the formation of international environmental agreements (IEAs). We show that the welfare of the signatories does not increase monotonically with respect to the number of signatories. We provide an analytical solution of the leadership model. In particular, we find that if the number of countries is greater than four then there exists a unique stable IEA with either two, three, or four signatories. Furthermore, we show that the welfare of the signatories is almost at its lowest level when the IEA is stable. While in our model each country's choice variable is emissions, we extend our results to the case where the choice variable is abatement efforts.     

Research cooperation and international standards in a model of coalition stability

Suggestions on international cooperation in climate policy beyond 2012 include substituting or complementing international environmental agreements (IEA) with technology-oriented agreements (TOA). We look at the impact of TOA on environmental cooperation in a framework of coalition stability. Using a numerical model, we analyze the differences of several TOA and how they interact. We find that participation in and environmental effectiveness of the IEA are raised less effectively when the TOA focuses on research cooperation in mitigation technology rather than cooperation on augmenting productivity in the private good sector. This is due to the former having an effect on all actors via emissions, whereas effects of the latter are exclusive to research partners. For the same reason, we find that restricting research cooperation to the coalition is only credible when it focuses on productivity. Technology standards that reduce the emission intensity of production are unlikely to raise participation by themselves and may suffer from inefficiencies. However, these disadvantages do not apply when standards are implemented as a complementary instrument. Separately negotiated technology standards may hence facilitate participation in an IEA without adding to its complexity.     

Self-enforcing International Environmental Agreements with Costly Monitoring for Compliance

Theoretical analyses of international environmental agreements (IEAs) have often employed the concept of self-enforcing agreements to predict the number of parties to such an agreement. The term self-enforcing, however, is a bit misleading. The concept refers to the stability of cooperative agreements, not to enforcing compliance with these agreements once they are in place. In this paper we analyze an IEA game in which parties to an agreement finance an independent monitor who audits the compliance performance of the members of an agreement. These audits reveal instances of noncompliance so they can be sanctioned. We find that costly monitoring of compliance limits the circumstances under which international cooperation to protect the environment is worthwhile, but when IEAs do form they will often involve greater participation than IEAs that do not require costly monitoring. Consequently, costly monitoring of IEAs can produce higher international environmental quality. Moreover, under certain conditions, aggregate welfare is higher when IEAs require costly monitoring.      

Climate Policy,Learning, and Technology Adoption in Small Countries

A significant reduction in global greenhouse gas emissions requires international cooperation in emission abatement as well as individual countries’ investment in the adoption of abatement technology. The existing literature on climate policy pays insufficient attention to small countries, which account for a substantial proportion of global emission. In this study, we investigate how climate policy and learning about climate damage affect investment in abatement technology in small countries. We consider three alternative climate policy instruments: emission standards, harmonized taxes and auctioned permits. We say that learning is feasible if an international environmental agreement (IEA) is formed after the resolution of uncertainty about climate damage. We find that, either with learning and quadratic abatement costs or without learning, harmonized taxes outperform emission standards and auctioned permits in terms of investment efficiency. Without learning, a large cost of nonparticipation (that a country incurs) in the IEA can be beneficial to the country. Whether learning improves investment efficiency depends on the size of this nonparticipation cost.     

A Dynamic Model for International Environmental Agreements

In this paper we develop a model that uses a dynamic framework to analyze the process through which countries join international environmental agreements (IEAs). In the model, while all countries suffer from the same environmental damage as a result of total global emissions, non-signatory countries decide on their emission levels by maximizing their own welfare, whereas signatory countries decide on their emission levels by maximizing the aggregate welfare of all signatory countries. It is assumed that signatory countries will be able to punish non-signatories, at some cost to themselves. When countries decide on their pollution emissions, they account for the evolution of the stock of pollution over time. Moreover, we propose a mechanism to describe how countries reach a stable IEA. The model is able to capture situations characterized by partial cooperation within an IEA that is stable over time. It also captures situations where all countries participate in a stable agreement, and situations where no stable agreement is feasible. Where more than one possibility coexist, the long-term outcome of the game depends on the initial conditions (i.e., the initial number of signatory countries and pollution level).     

The Incentives for North-South Transfer of Climate-Mitigation Technologies with Trade in Polluting Goods

The need to transfer climate mitigation technologies towards the developing world has been acknowledged since the beginning of climate negotiations. Little progress has however been made, as shown by Article 10 of the Paris Agreement. One reason is that these technologies could become vital assets to compete on global markets. This paper presents a partial equilibrium model with two regions, the North and the South, and imperfect competition in the international polluting goods market, to analyze the North’s incentives to accept technology transfer. Results crucially depend on the existence of environmental cooperation. When both northern and southern governments set emission quotas non-cooperatively, inducing fewer global emissions is a necessary, but not sufficient condition for the North to accept the transfer. In contrast, when governments set quotas cooperatively, the North has no incentive to share its technology either before or after the agreement. Technology transfer commitments may be included in the agreement, but with no effect on global emissions and global surplus. The only impacts are distributional, technology transfers and side payments may be substitute instruments.     

International Environmental Permit Trade and Debt: the Consequences of Country Sovereignty and Cross-Default Policies*

We investigate the joint occurrence of international intertemporal trade and international environmental-permit trade, both of which are subject to country sovereignty. Assuming that side payments cannot be made to keep a debtor country from terminating international environmental cooperation, we analyze the impact of these two trade opportunities on a debtor country's incentive to continue environmental cooperation. We also show how, by way of a suitable strategic linkage between debt and permit trade, the public good of ensuring continued environmental cooperation can be provided by the supply side of private international loans.     

Coalition Stability in Public Goods Provision: Testing an Optimal Allocation Rule

We test the canonical model of international environmental agreements (IEAs) in a laboratory setting with asymmetric agents. IEA participation represents coalition formation and public good provision where there are gains to cooperation, but an incentive to free-ride. We test four competing methods of dividing the coalition’s worth: a recently proposed optimal rule which accounts for subjects’ payoffs as a single free-rider, the Shapley value, the Nash bargaining solution, and an equal split. Each treatment generates the theoretically predicted coalition size more often than not. The shares of the potential gains to cooperation achieved by each rule are: 51, 36, 40 and 13%, respectively. These results highlight the importance of using an optimal rule to improve IEAs, and more broadly for voluntary public good provision.     

Trade Liberalization and Environmental Regulation on International Transportation

Incorporating pollution emissions from international transportation into a model of strategic trade and environmental policies, we investigate the effect of trade liberalization and environmental regulation on national welfare and the environment. Our model includes imperfectly competitive markets for international transportation and final products. We find that trade liberalization may reduce each country's welfare unless some level of environmental regulation on international transportation is in place. When international trade is liberalized initially, a mutual increase in the common emission tax rates may improve each country's welfare. However, when international trade is highly protected initially, imposing an emission tax may reduce welfare.     

Political stability,corruption and trust in politicians

In this article we develop a dynamic model where an endogenous evolution of trust impacts a politician's choice for bribe-taking and tax re-distribution. The politician obtains utility from net income that comes from his wage income, tax embezzlements and bribe-taking, and he also has incentives for tax re-distribution. The higher the tax embezzlements and the more bribes the politician takes the lower his citizens' trust and the less likely will he be re-elected. We support the evolution of trust with an econometric investigation.We analyze the necessary and sufficient conditions, and find that withholding taxes and taking bribes may be complements or substitutes for a politician, depending on the politician's incentives for tax re-distribution. Without these incentives, tax embezzlement and bribe taking are necessarily substitutes. With sufficiently strong incentives, we find re-distribution and bribe-taking may become complements. Complements implies that the politician, at least partly, increases bribe-taking because this allows him to increase re-distribution, which aids his additional motives for tax re-distribution.Based on comparative statics at steady state we also find that the higher the politician's wage the lower the bribe-taking and the higher the trust; stronger social capital leads to less bribe-taking and higher levels of trust; improvements in electoral accountability induce a decrease in bribing while trust increases.     

The effects of tariffs on coalition formation in a dynamic global warming game

The prospects for cooperation on climate protection beyond 2012 are currently uncertain. Thus policy instruments which foster participation in International Environmental Agreements (IEA) are in demand. Among the instruments under discussion are trade sanctions. Multi-region optimal growth models are a state of the art tool for integrated assessment, but introducing trade sanctions distorts the competitive equilibrium, making it difficult to compute numerically. We introduce trade and trade sanctions into a model of coalition stability to assess the potential of trade sanctions to support an IEA. Trade is modeled by having all countries produce a generic output good, but adopting national product differentiation (Armington assumption). Coalitions are free to impose tariffs on imports from non-cooperating countries. We solve the model numerically using a refined version of Negishi's [Negishi, T., 1960. Welfare economics and existence of an equilibrium for a competitive economy. Metroeconomica 12, 92–97] basic algorithm. We then apply the model to analyze the influence of tariffs on international cooperation. The model suggests that there is indeed a significant potential to raise participation through trade sanctions, even when goods from different countries are nearly perfect substitutes. Furthermore we investigate the effect of trade sanctions on global welfare, environmental effectiveness, and the credibility of the tariff mechanism.     

The Oslo Protocol on sulfur reduction: the great leap forward?

The increasing number of international environmental agreements (IEAs), and the fact that under some agreements emissions have been reduced beyond agreed targets, are frequently viewed as success stories of international cooperation. We argue that success can only be measured if abatement targets under an IEA are compared with estimated abatement levels in the absence of a treaty, and are evaluated in terms of costs and benefits. We analyze the Oslo Protocol on sulfur reduction, showing that this IEA is not the great leap forward when compared with the calculated Nash equilibrium and the social optimum. However, we also demonstrate that under the Oslo Protocol, more ambitious targets could not have been realized due to strong free rider incentives.     

Market competition,lobbying influence and environmental externalities

In this paper, we contribute to the debate regarding the relationship between lobbying and environmental regulation by explicitly taking into account the role of market competition. We analyse how the number of firms affects both the effectiveness of lobbying in fighting environmental regulation and the individual incentive for firms to switch to green technology. To explore this issue, we present a Cournot oligopoly where firms can choose between abating the environmental externality or lobbying the government to hold a loose regulation. We investigate two alternative government's political objectives. In the first, government aims to only minimise the externality, while in the second, it also cares about the consumers surplus. We find that, in both cases, the higher the number of firms, the higher the incentive to abate. However, while in the first case, either both types of firms coexist or all firms switch to be green, in the other case, there exists a minimum the number of firms below which all firms remain polluting.     

Implementation without incentive compatibility: Two stories with partially informed planners

We consider two stories, Typhoon by Conrad and Traveler's Dilemma by Basu, 1994, Basu, 2007, as implementation problems under incomplete information without incentive compatibility, but where the planner has some private information regarding the state. If social choice functions do not satisfy incentive compatibility, full implementation is unattainable via existing approaches. For each story, we construct a direct mechanism that relies on the planner's private information. We provide a sufficient condition on players' beliefs regarding the state under which every player has a unique rationalizable action, namely, telling the truth. Thus, in these stories, the planner's information can bypass the lack of incentive compatibility.     

Transboundary Pollution and International Migration

We analyze the welfare effects of international migration in the presence of transboundary pollution. We use a simplified Copeland and Taylor (1999) model, where the (developed) home country's pollution abatement technology is superior to that of the (less developed) foreign country. If there is no trade, workers will migrate from the foreign country to the home country. The foreign country gains from migration, but whether the home country gains or not depends on the abatement‐technology gap and the magnitude of the coefficient of transboundary pollution. World welfare will increase under migration. If there is free trade in goods, international migration occurs when the home country specializes in the production of the environmentally sensitive good. In this case, migration will result in increased production of the manufactured good and increase the level of world pollution.     

Environmental Product Standards in North–South Trade

Consumption is one channel through which the environment is damaged. To protect the environment, various product standards have been introduced across the world. This paper uses a new economic geography framework to explore the effects of environmental product standards on environment in a North–South trade model. It examines the situation in which the North unilaterally introduces an environmental product standard. Specifically, those products that do not meet the standard are not allowed to be sold in the North's market. It is found that such a standard may worsen the North's environment but improve the South's environment as a result of firm relocation.     

Negotiation over Intellectual Property Rights Protection in a Mixed Market

This article models a North–South negotiation under a mixed oligopolistic setting where a public firm in the South and a private firm from the North compete in the southern market. The southern firm is a public one whose objective is a weighted sum of the South's social welfare and its own profit, whereas the northern firm is a pure profit maximizer. The North provides a quid pro quo in exchange for the strengthening of the enforcement of intellectual property rights (IPR) protection in the South. We show that when the northern and southern firms engage in quantity competition in the southern market, the southern government's optimal choice is either complete protection or complete violation. We show this to depend on the southern government's valuation of the quid pro quo. Moreover, strengthening IPR protection will deepen the privatization process in the South, though it brings about a social welfare loss to the South.     

The Managers versus the Consultants*

Since engineering information is rarely available, standard practice is to benchmark managerial performance against best observed practice. We exploit a rare opportunity to benchmark managerial performance against engineering standards. Our managerial performance describes the activities of Spanish electricity distributors, and our engineering standards are obtained from an engineering grid created by an international consultancy. We find the consultancy's network to be much less costly to operate. When we decompose the cost differential, we find that the superior network design, combined with lower input prices, accounts for more than all of the predicted cost savings. However we also find that the managers are more cost efficient than the consultancy, presumably because they exploit their incentive to be cost efficient under a revenue cap regulatory regime.     

Environmental regulation and technology transfers

This paper analyzes the situation in which a national government introduces environmental regulations. Within the framework of an international duopoly with environmental regulations, an environmental tax imposed by the government in the home country can induce a foreign firm with advanced abatement technology to license it to a domestic firm without this technology. Furthermore, when the domestic firm's production technology is less efficient than that of the foreign firm, the foreign firm may freely reveal its technology to the domestic firm. These improvements through the voluntary transfer of technology imply that environmental regulations have positive impacts on innovation.
