Regional development or resource preservation? A perspective from Japanese appliance exports

This paper examines Japanese resource outflows in the form of exported used (and functional) products in 2007 by quantifying the unintentional metal exports for a number of specialty metals typically used in electronics and electrical equipment. We find that more than half of the indium and 20-30% of the barium, lead, antimony, strontium, zirconium, silver, gold, and tin in domestically discarded products were not recycled in Japan, but rather were exported in products to be used elsewhere. The destinations of these metals were mainly Asian countries with rudimentary recycling technology. These results demonstrate that although these metals could have been stockpiled domestically for future recovery and recycling, they were instead sent to countries where recycling of these scarce metals is unlikely. From a resource perspective, therefore, the free trade of used Japanese products compromises long-term domestic resource availability as it increases the quality of life in developing countries.     

Mineral resources for renewable energy: Optimal timing of energy production

The production of energy from renewable sources is much more intensive in minerals than that from fossil resources. The scarcity of certain minerals limits the potential for substituting renewable energy for scarce fossil resources. However, minerals can be recycled, while fossil resources cannot. We develop an intertemporal model to study the dynamics of the optimal energy mix in the presence of mineral intensive renewable energy and fossil energy. We analyze energy production when both mineral and fossil resources are scarce, but minerals are recyclable. We show that the greater the recycling rate of minerals, the more the energy mix should rely on renewable energy, and the sooner should investment in renewable capacity take place. We confirm these results even in the presence of other better known factors that affect the optimal schedule of resource use: expected productivity growth in the renewable sector, imperfect substitution between the two sources of energy, convex extraction costs for mineral resources and pollution from the use of fossil resources.     

Hotelling and recycling

We study the exploitation of recyclable exhaustible resources such as metals that are crucial for the energy transition or phosphorus that is crucial for agricultural production. We use a standard Hotelling model of resource exploitation that includes a primary sector and a recycling sector. We study two polar cases: competitive and monopolistic extraction. We show that, when the primary sector is competitive, the Hotelling’s rule holds and the price of the recyclable resource increases over time. We then show a new reason why the price of an exhaustible resource may decrease: when the primary sector is monopolistic, the primary producer has incentives to delay its production activities in order to delay recycling. As a consequence, the price path of the recyclable resource may be U-shaped. Numerical simulations reveal that the monopolist has an incentive to delay extraction when the recoverability rate is high (because more recycled goods are produced) or when the recoverability rate is low (when fewer recycled goods are expected to be produced in the future). As a consequence, the date of exhaustion of the virgin resource is further away in time for high and low levels of recoverability than for intermediate levels.     

Consumption patterns of food,tobacco and beverages: a cross-country analysis

This study considers the consumption patterns of food, tobacco, soft drinks, and alcohol in 43 developed and developing countries. Such an analysis is important for policy issues associated with tobacco, alcohol, and soft drinks. The results show that consumers in the developing countries spend a much higher proportion of their income on food than consumers in developed countries. The proportion of expenditure allocated to the other three commodities, tobacco, alcohol, and soft drinks, are similar in the two groups of countries. On average, people around the world allocate about one quarter of their income on food, 2.6% on tobacco, 3.2% on alcohol and 1.2% on soft drinks. The income elasticity estimates reveal that food is a necessity in most countries, while tobacco and alcohol are necessities in most of the developed countries and luxuries in a majority of developing countries. Soft drinks are a luxury in a majority of the developing as well as the developed countries. The own-price elasticities show that demand for all four commodities is price inelastic in all countries.     

Exhaustible resources,technology choice and industrialization of developing countries

How should the world economy adapt to the increased demand for exhaustible resources from countries like China and India? To address that issue, this paper presents a dynamic model of the world economy with two technologies for production; a resource technology, which uses an exhaustible resource as an input and an alternative technology, which does not. I find that both the time path of resource extraction and the adoption of the alternative technology depend on the optimal allocation of capital across the technologies, and on the size of the capital stock in relation to the resource stock. In particular, if the capital stock is low, only the resource technology is used initially and the alternative technology is adopted with a delay. Next, I use the model to analyze the effects of industrialization of developing countries on the extraction of oil and technology choice for energy production. As a result of industrialization, the alternative technology for energy production is adopted earlier.     

Capital Accumulation and Resource Depletion: A Hartwick Rule Counterfactual

How much produced capital would resource-abundant countries have today if they had actually followed the Hartwick Rule (invest resource rents in other assets) over the last 30 years? We employ time series data on investment and rents on exhaustible resource extraction for 70 countries to answer this question. The results are striking: Venezuela, Trinidad and Tobago, and Gabon would all have as much produced capital as South Korea, while Nigeria would have five times its current level. A specific rule for sustainability – maintain positive constant genuine investment – is shown to lead to unbounded consumption.

Urbanization with and without industrialization

We document a strong positive relationship between natural resource exports and urbanization in a sample of 116 developing nations over the period 1960–2010. In countries that are heavily dependent on resource exports, urbanization appears to be concentrated in “consumption cities” where the economies consist primarily of non-tradable services. These contrast with “production cities” that are more dependent on manufacturing in countries that have industrialized. Consumption cities in resource exporters also appear to perform worse along several measures of welfare. We offer a simple model of structural change that can explain the observed patterns of urbanization and the associated differences in city types. We note that although the development literature often assumes that urbanization is synonymous with industrialization, patterns differ markedly across developing countries. We discuss several possible implications for policy.     

General Equilibrium Tragedy of the Commons

Many poor economies depend on open access resources for their livelihoods. Households in resource-based economies allocate their time and other factors between resource extraction and other activities. As a result, factors may shift from one sector to another as marginal returns change. This has two important implications. First, it implies potentially strong linkages between resource and non-resource sectors. Second, it means that unmanaged resources cause inefficient allocations of inputs across all sectors, and the effects of resource management spill into other sectors. We construct a local general equilibrium model that accounts for inputs that over-allocate to an open access resource and create a general equilibrium tragedy of the commons. This model describes resource rent dissipation more adequately in economies with mobile factors than a model with slowly dissipating rents. Perfectly mobile factors dissipate rent in every period, but endogenous wages cause labor and capital allocations to change with the resource stock. We use the model to illustrate medium-run impacts of a limit on capital in an artisanal fishery in Honduras. Simulation results reveal that fishery management has economy-wide impacts on prices and wages. Managers in developing countries thus should consider these linkages when implementing policies to conserve fish stocks.     

BUSINESS CYCLES IN SMALL OPEN ECONOMIES: EVIDENCE FROM PANEL DATA BETWEEN 1900 AND 2013

Using a novel data set for 17 countries between 1900 and 2013, we characterize business cycles in both small developed and developing countries in a model with financial frictions and a common shock structure. We estimate the model jointly for these 17 countries using Bayesian methods. We find that financial frictions are an important feature for not only developing but also small developed countries. Furthermore, business cycles in both groups of countries are marked with trend productivity shocks. Common disturbances explain one third of the fluctuations in small open economies, especially during important worldwide phenomena.     

外包与技术转移:基于发展中国家异质性模仿的分析

本文构建了一个模型来研究外包以及依附于外包活动中的技术转移,对发展中国家经济发展的多重影响效应.我们的研究表明,在发展中国家为低模仿类型时,外包活动中发达国家对发展中国家的技术转移,有利于发达国家与发展中国家双方的福利增进;在发展中国家为高模仿类型时,技术转移有利于发达国家,而不利于发展中国家可持续发展能力的培育.我们的研究支持这样一种观点:外包条件下发达国家对发展中国家的技术转移,并不必然会带来发展中国家的经济可持续增长,一个不可忽略的必要条件是,发展中国家自身制度条件制约了外包与技术转移对发展中国家可持续发展能力的作用.     

Long-Run Implications for Developing Countries of Joint Implementation of Greenhouse Gas Mitigation

Joint Implementation (JI) calls for cooperation between industrialized and developing countries in the mitigation of greenhouse gas (GHG) emissions. However, a major concern of potential host countries is that, if they utilize their low-cost options for JI now, they will be left with only high cost options in the future, thereby penalizing them at a time when they may be obligated to mitigate GHGs themselves. This paper formalizes this hypothesis by utilizing an optimal control framework analogous to the Hotelling model of non-renewable resource extraction. The results are that cumulative abatement effects can impose costs on the future, but that they can be offset by technological change, market power, or compensation.     

The curse of natural resources in the transition economies*

The curse of natural resources is a well‐documented phenomenon for developing countries. Economies that are richly endowed with natural resources tend to grow slowly. Among the transition economies of the former ‘Eastern Bloc’, a similar pattern can be observed. This paper shows that a large part of the variation in growth rates among the transition economies can be attributed to the curse of natural resources. After controlling for numerous other factors, there is still a strong negative correlation between natural resource abundance and economic growth. Among the transition economies the prime reasons for the curse of natural resources were corruption and a neglect of basic education. In order to overcome the curse of natural resources and move to a sustainable path of development, the resource abundant transition countries should fight corruption and ensure that their resource revenues are invested in human capital or the preservation of natural capital.     

Spatial modeling of extraction and enforcement in developing country protected areas

Budget constraints prohibit protected area managers (PAMs) in developing countries from completely deterring extraction and the resulting resource degradation. Because benefits from extraction are a function of distance, PAMs have an opportunity to patrol in a spatial pattern that minimizes degradation for a given budget level. This paper develops a spatial model of a game between a PAM and neighboring villagers to determine the optimal patterns of extraction and enforcement under various constraints. It demonstrates the importance of spatial aspects of PA management, reveals the inefficiency of many PA policies, and supports explicitly spatial management schemes such as extraction zones. The framework underpins a discussion of incomplete enforcement, rural welfare, budgetary tradeoffs between PA size and enforcement costs, and PA shape decisions with human-induced edge effects.     

On the Dynamics of Recycling and Natural Resources

We study the dynamic impact of recycling through its effect on the production set of the economy and its relationship with natural resources. The contribution of renewable and recyclable resources for sustainability is studied. Although in the short run recycling may alleviate resource scarcity, in the long run it is not enough to compensate for the exhaustibility of non-renewable resources and the possibility of obtaining non-decreasing output paths crucially depends on the extent to which production rests on renewable resources. Furthermore, recycling interacts with natural resource growth, surprisingly not always favoring sustainability. The Production and Recycling Function is a generalization of the traditional production function, providing an integrated view of regular production and recycling and representing the production set of the economy when a recycling technology is available.     

Sustainable management of renewable resources: an experimental investigation in continuous time

This study addresses one of the most basic questions in renewable resource management: the ability of economic agents to exploit a renewable resource in an efficient and sustainable manner. In a laboratory experiment, subjects are presented with renewable resource extraction problems, where optimal management will lead to a stable steady state. A test of sustainability of the extraction practices shows that extraction behaviour results in steady states only 56% of the time. The mode of the steady state distribution coincides with the optimal steady state extraction. The trade-off between accruing a higher payoff in the present and sustaining the resource for future exploitation leads to suboptimal behaviours such as initial overextraction of the resource compared to the optimal extraction policy, costly downward adjustment of the extraction later in time, and settling down for lower long-run resource and extraction. The suboptimal behaviours lead to 17% loss in efficiency on average in terms of the accumulated payoff. We further look at extraction behaviour in terms of the degree of impatience it projects and find, based on their extraction decisions, that most of our subjects seem more impatient in managing their resource than is justified by the decision-making problem presented to them.     

Complexities of Decentralization in a Globalizing World

In many developing countries, decentralization programmes for natural resource management aim to induce incentives for sustainable resource management at the local level. The effectiveness of such programmes has, however, suffered from weak property rights to the resource and by the presence of externalities. Growing economic integration among countries has exacerbated these problems by increasing the exposure of local user groups to commercial actors interested in resource extraction. In this paper, the interplay of decentralization and globalization in affecting environmental outcomes and community welfare is analysed through a game-theoretic model of community-firm interactions. The results highlight the complexities of policy design. First, by raising the extractive value of the resource, globalization may lead to communities negotiating resource extraction agreements with firms. Second, with a lack of effective state enforcement of community resource rights, communities may be unable to assume de facto ownership over the resource, while commercial actors succeed in exploiting resources without community consent. No single policy option provides a panacea to counteracting these negative effects. Instead, a mix of policies, combining incentive payments along with the provision of more secure property rights and poverty alleviation is shown to have the potential to improve both environmental outcomes and community welfare.     

技术选择、制度与经济发展

Lin(2003)的研究表明,大多数发展中国家没有成功地缩小与发达国家的收入差距,主要根源在于它们的政府采取了不适当的发展战略——赶超战略。本文试图将Lin(2003)的上述思想初步模型化,在统一的技术选择模型的框架内研究发展战略、自生能力以及以扭曲的价格、计划的资源配置和缺乏自主权的微观主体为特征的三位一体经济体制之间的关系,并在此基础上,研究发展战略和这个三位一体经济体制对经济收敛的影响。     

Intellectual property rights and the upgrading of the global value chain status

The present paper explores how intellectual property rights (IPR) protection affects an economy’s status in global value chains (GVC) by introducing IPR protection into the sequential production model. We find that a suitable IPR protection system that matches the phase of economic and technological development a country has reached is the key for developing countries to upgrade their status in GVC, which are dominated by multinational firms from developed countries. Empirical analysis with multinational panel data for 55 countries from 2005 to 2015 provides evidence in support of the predictions of this model, although the GVC‐enhancing effects of IPR protection are heterogeneous for developing and developed countries. The empirical conclusions are robust after using the instrumental variable method and controlling for endogeneity.
