PROJECT EVALUATION AND RESOURCE SUSTAINABILITY

This paper outlines a procedure for embodying the principle of resource sustainability in evaluating projects that use significant amounts of natural resources. In this analysis, sustainability requires maintaining the productivity of the resource used over time, either by renewing the resource or by investing its depletion in other capital assets. The basis of a project's evaluation is its net present social value (NPSV), including resource depletion as a social cost. The social cost of depletion is the amount that must be saved and reinvested annually to accumulate a fund that will yield a perpetual annual income equal to the net output lost by resource depletion. By treating resource depletion as a social cost in calculating NPSV, projects causing a high rate of resource depletion receive a relatively low valuation compared with projects causing less resource depletion. Resource depletion includes environmental damage caused by constructing and operating a project, as well as the direct consumption of natural resources.
Several problems arise in reinvesting depletion to preserve the value of a resource base. One major problem relates to the substitutability of man-made capital for natural resources. The conclusion of the analysis here is that society must invest a substantial amount of resource depletion in: (i) replenishing renewable resources, (ii) increasing product output per unit of resource used, or (Hi) increasing the end-use efficiency of resource-intensive products.     

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.     

Environment, human development and economic growth

Over the last few years, environmental issues have entered into policy design, particularly development and growth policies. Natural resources are considered necessary production inputs and environmental quality is considered a welfare determinant. The integration of environmental issues into economic growth and development theories and empirics is currently widely analyzed in the literature. The effects of natural resources endowment on economic growth are mainly analyzed through the so-called Resource Curse Hypothesis (RCH) whereas the effects of economic growth on environmental quality are part of the Environmental Kuznets Curve (EKC). Furthermore, recent contributions on RCH and EKC have shown the important role of institutions and human development dimensions in building a sustainable development path. In this paper, we attempt to analyze the causal relationships between economic growth, human development and sustainability combining the RCH and EKC models and adopting a human development perspective. Results confirm the importance of high institutional quality and investments for human capital accumulation in order to build a sustainable development path.     

Conditions for Sustainable Optimal Economic Development

This paper shows that, for dynamic optimizing economies with different types of natural resource, environmental, and human‐made capital stocks, a necessary and sufficient condition for permanently sustaining an optimal utility/consumption level is the stationarity of the current‐value Hamiltonian. For economies whose development is not exogenously and directly affected by time (i.e., time‐autonomous economies), this stationarity condition generalizes Dixit et al.’s (1980 ) “zero‐net‐aggregate‐investment” rule of sustain‐ability, which in turn generalizes Solow‐Hartwick’s sustainability rule. For non‐autonomous economies, the stationarity condition is not generally fulfilled, and the current‐value Hamiltonian under (over) estimates the true welfare level by an amount equal to the discounted value of the net “pure time effect.” For the non‐autonomous case of a time‐dependent utility discount rate, a general condition on the discount rate function (of which the hyperbolic discount rate function is a special case) upholds the results obtained for autonomous cases. The paper concludes with a discussion of policies that promote both optimality and sustainability objectives.     

Distributive impact of structural change: Does environmental degradation matter?

Vulnerability to reduction of natural capital depends on defensive substitution possibilities that, in turn, are affected by the availability of other productive factors. However in several developing countries asset distribution tends to be highly skewed. Taking into account these elements, this paper proposes a model considering an economy polarized into two classes (the rich and the poor) and characterized by the following stylized facts: income and productivity of the rural poor is highly dependent on natural resources; labour remuneration in rural sector represents the opportunity cost for wage labour; the rich can partially substitute natural capital with physical capital and wage labour. In this context, agents differ for feed back mechanisms and interactions between their choices of production and environmental dynamics. Moreover environmental depletion may trigger economic transition, but the structural change is likely to result regressive.     

Canada’s dependence on natural capital wealth: Was Innis wrong?

Canada has abundant natural resources—its stock of natural capital wealth. A recurring debate in the literature is whether resource rich countries benefit in the form of higher sustained growth rates or not from the export of their natural resources. Canada's Harold Innis wrote extensively on this subject over 80 years ago and argued for the “no” side in the debate. Was he was right or wrong? I begin with the foundations of natural resource theory then turn to empirical work in recent decades. I agree with the literature that Canada overall has benefited from the export of its natural resources, but question whether that can continue given the focus on short term growth and the failure to account for the social costs of resource extraction and use—the environmental externalities that degrade and reduce stocks of natural capital. These externalities increasingly threaten our water and land resources and without more effective policy, the ability of resources to sustain growth and well‐being is questionable. Was Innis wrong? Yes in that the evidence supports the counter argument—resources have helped Canada become a developed economy with relatively high incomes and sustained growth rates. Innis was right that the uneven distribution of resources causes different impacts regionally especially during booms and busts and recognized the need to find substitutes for declining and degrading resource stocks. But Innis, like many after him, focused more on the intrinsic features of natural resources than policy to address the social costs of their development, a legacy that leaves us in a precarious position today.     

自然资源丰裕程度与经济发展水平关系的研究

“资源的诅咒”是经济学中的一个经典假说,但这一命题在一国内部不同地区是否成立尚缺乏验证。本文以中国的省际面板数据为样本,对这一假说进行了实证检验。计量结果显示,该命题在我国内部的地区层面同样成立,多数省份丰裕的自然资源并未成为经济发展的有利条件,反而制约了经济增长。自然资源的丰裕以及对这种资源的依赖,主要是通过资本投入的转移机制制约了经济增长,劳动投入的转移机制也存在这种效应,但不如前者显著。本文选择山西为典型省份,进一步揭示“资源的诅咒”的作用机制。结果表明,密集而过度的资源开采引致的制造业衰退和制度弱化是制约经济增长的主要原因。     

Why do many resource-rich countries have negative genuine saving?: Anticipation of better times or rapacious rent seeking

We investigate the Hartwick rule for saving of a nation necessary to sustain a constant level of private consumption for a small open economy with an exhaustible stock of natural resources. The amount by which a country saves and invests less than the marginal resource rents equals the expected capital gains on reserves of natural resources plus the expected increase in interest income on net foreign assets plus the expected fall in the cost of resource extraction due to expected improvements in extraction technology. Effectively, depletion is then postponed until better times. This suggests that it is not necessarily sub-optimal for resource-rich countries to have negative genuine saving. However, in countries with different groups with imperfectly defined property rights on natural resources, political distortions induce faster resource depletion than suggested by the Hotelling rule. Fractionalised societies with imperfect property rights build up more foreign assets than their marginal resource rents, but in the long run accumulate less foreign assets than homogenous societies. Hence, such societies end up with lower sustainable consumption and are worse off, especially if seepage is strong, the number of rival groups is large and the country does not enjoy much monopoly power on the resource market. Genuine saving is zero in such societies. However, World Bank genuine saving figures based on market rather than accounting prices will be negative, albeit less so in more fractionalised societies with less secure property rights.     

Consumer Capital as the Source of Happiness: The Missing Economic Theory Underlying the Income-Happiness Paradox

Self-reported happiness does not generally increase with rising income, as established by Richard Easterlin. We argue that the current debate in economics about the income-happiness paradox has paid too little attention to the theoretical foundation of the expected positive relation between income and happiness, seeking an empirical resolution through better data and more elaborate estimating equations instead. We return to the history of economics and revisit the contributions of Irving Fisher and Kenneth Boulding for the missing economic theory that underlies the income-happiness paradox. According to both Fisher and Boulding, “consumer capital” is the ultimate source of welfare, whereby consumer capital is defined as an accumulated stock of tangible and intangible instruments that yield a stream of services over their useful life. In the view of Fisher and Boulding, it is the utilization of this capital stock that renders happiness to individuals. Moreover, income that pays for the goods of consumption can be a “bad,” reflecting the cost of maintaining the consumer capital stock. Therefore, Fisher and Boulding’s insights bring a new perspective to the Easterlin paradox, showing that the empirical finding that rising income contributes only little, if anything, to levels of happiness has been overemphasized at the expense of the theoretically more relevant relation between consumer capital and happiness, and the exact role of income therein.     

INTEGRATED ENVIRONMENTAL AND ECONOMIC ACCOUNTING: FRAMEWORK FOR A SNA SATELLITE SYSTEM

National accounts have provided the most widely used indicators for the assessment of economic performance, trends of economic growth and of the economic counterpart of social welfare. However, two major drawbacks of national accounting have raised doubts about the usefulness of national accounts data for the measurement of long-term sustainable economic growth and socio-economic development. These drawbacks are the neglect of (a) scarcities of natural resources which threaten the sustained productivity of the economy and (b) the degradation of environmental quality from pollution and its effects on human health and welfare. In the present paper, the authors attempt to reflect environmental concerns in an accounting framework which maintains as far as possible SNA concepts and principles. To this end, the accounting framework is used to develop a "SNA Satellite System for Integrated Environmental and Economic Accounting" (SEEA). Environmental costs of economic activities, natural asset accounts and expenditures for environmental protection and enhancement, are presented in flow accounts and balance sheets in a consistent manner, i.e. maintaining the accounting identities of SNA. Such accounting permits the definition and compilation of modified indicators of income and expenditure, product, capital and value added, allowing for the depletion of natural resources, the degradation of environmental quality and social response to these effects. A desk study of a selected country is used to clarify the proposed approaches, to demonstrate their application in future country studies and to illustrate the quantitative effects of the use of modified concepts on the results of analysis.     

Can innovation shocks determine CO2 emissions (CO2e) in the OECD economies? A new perspective

ABSTRACT

This study has attempted to address prior knowledge gaps in the environmental economics literature by integrating the innovation shocks into the Environment Kuznets Curve (EKC) equation for twenty-six OECD economies using data from 1990 to 2014. Foreign direct investment (FDI), exports (EXP), renewable energy consumption (REC), and GDP per capita were included as control variables. The results from multiple empirical analyses indicated that positive shocks to innovation improve, but the negative shocks disrupt environmental quality. Data analyses also showed that a positive correlation exists between income per capita of OECD economies. From the negative coefficient of income per capita (squared) and the existence of a negative nexus between FDI and CO2e, both the EKC and the Pollution Halo Hypothesis (PHH) were confirmed in sampled economies, respectively. The paper offers empirical support for the favourable impacts of REC on the quality of the environment and calls for the adoption of innovation shocks as a policy instrument to formulate better environmental policies for a sustainable future.     

Vested Interests and the Common People in Developing Countries: Understanding Oppressive Societies and Their Effects

The standard economic model of how economies work is that activities are essentially productive. This is not a correct view of reality. The principal difficulty is that there is economic activity that is unproductive and harmful (from the point of view of those being harmed). This is a central feature of the economic organization of these societies, and creates poverty. The first section of the article discusses the concept of harm. The second section describes how societies are run on this basic set of principles: Take and maintain control of the government and other aspects of society, and use the power of government to obtain income. The third section of the article describes how this system harms the common people. Topics include corruption, misappropriation of natural resources, conflict and other harm engendered by the struggle for control, the influence on present society of the past operation of harmful economic systems, and discrimination as well as other “barriers to entry.”     

Economic Convergence,Capital Accumulation,and Income Traps: Empirical Evidence

This paper examines the factors that increase the likelihood of economic transition to higher income status, thereby attempting to answer the question of why some economies move to a higher income country group while others do not. Using a quintile income distribution approach, we identify 62 economies that moved to a higher quintile income group in each decade from 1960s to the 2010s out of a sample of 182 economies. Our findings show that higher physical and human capital growth and oil revenues are significantly associated with a greater probability of transitioning to higher quintile income group, although their effects vary not only across income groups within a sample period but also across different periods. Our results indicate that economies that have attained substantial capital accumulation (either physical or human, or combination thereof) and/or are blessed with natural resources have avoided income traps and demonstrated a successful and often steady transition to higher income groups.     

Has Canada's 21st-Century Grand Gender Convergence Stalled? Male and Female Income and Human Resource Stock Distributions Viewed Through an Equal Opportunity Lens

The increasing similarity of male and female labor market roles in advanced economies over the past 50 years, dubbed the “Grand Gender Convergence” by Goldin (2014), appears to have stalled. Given commonality of preferences for work and human resource acquisition across the gender divide, women and men with similar human resources and efforts should have similar income distributions in a non-discriminatory equal opportunity equilibrium. However, income convergence is a necessary but not sufficient condition for a “Grand Gender Convergence” as similarities in incomes could be achieved with differences in human resources and efforts given discriminatory rewards. In this study, using new tools for examining distributional convergence processes, the progress of Canada's 21-st Century “Grand Gender Convergence” is examined in the context of an equal opportunity paradigm. While income convergence is almost universally apparent, human resource stock distributions appear to be diverging, with women having increasingly superior resources to men, evidence that the grand convergence is not progressing.     

INCOME UNCERTAINTY,CONSUMER DURABLES INVESTMENTS,AND HOME PRODUCTION: EVIDENCE FROM CHINA

We investigate the effect of uncertainty on home durable purchase decisions, and empirically evaluate the efficacy of consumer durable policies under uncertainty. A model of lumpy home capital adjustment shows that elevated uncertainty leads households to adopt a cautionary perspective and postpone their capital adjustment. We test this prediction using microevidence from China where both uncertainty and home production are substantial. We exploit a wide‐scale rebate program funded by the Chinese government as a natural experiment, and examine the impact on household investment. We find strong, significant, and robust evidence that greater income uncertainty inhibits durable adjustment. Our findings highlight the impediment that income uncertainty poses to investment in home durables, which are often considered as “engines of liberation” in emerging economies.

Dynamite in the EKC tunnel? Inconsistencies in resource stock analysis under the environmental Kuznets curve hypothesis

Recent studies incorporating consumption into the relationship between GDP and conservation increasingly reveal that economic prosperity does not lead to improvements in environmental quality, even in cases where rich countries may appear to protect a greater proportion of their domestic resources. This study reinforces those findings for forest and species conservation across two groups of countries. Additionally, through explicit comparison with two previous EKC studies, I enable an illustration of precisely how EKC results are affected by the incorporation of consumption and highlight persistent problems with EKC analyses. Despite general linear modeling results showing that wealthy countries drive deforestation in poorer countries through the import of forest resources, EKC analyses can still indicate improvements in conservation for wealthier countries. Such contradictions suggest that recent methodological improvements to the EKC cannot guarantee the validity of evidence from EKC analyses. Poor quality of resource stocks data, the restrictive time scales that can be examined with those data, and the lack of consistent results across different groups of countries all speak to continued inadequacies of the EKC hypothesis and the need to focus on approaches that address actual behavior patterns exhibited by different income groups.     

Japanʼs intangible capital and valuation of corporations in a neoclassical framework

This paper estimates the economic value in the 1980s and 1990s of corporate assets in Japan, including both tangible and intangible assets, based on the neoclassical framework of McGrattan and Prescott (2005). Our estimates use a new micro-data set that comprises the accounting statements of all listed, non-financial companies in Japan. We find that in 1980–1986, a period that immediately preceded Japan?s so-called “bubble economy”, our assessed value of corporate productive assets, net of the value of corporate debt, is approximately equal to the actual stock market value of Japanese corporate equity. The finding differs from previous results based on studies of aggregate data sets or based on studies of micro-data sets that neglected intangible capital. We also show that the Japanese ratio of the amount of intangible capital stock to the amount of tangible capital stock is comparable to the analogous ratios for the U.S. and U.K.     

Wealth Accounting,Exhaustible Resources and Social Welfare

The empirical literature on natural resource accounting uses methods which implicitly or explicitly entail measuring changes in total resource asset value when an exhaustible resource is depleted. In contrast, the growth theoretic literature on saving, social welfare and sustainable development is built upon a central finding, that the change in real wealth (as measured by net or ‘genuine’ saving) is proportional to the change in social welfare. We show that the change in total wealth exceeds the change in real wealth in optimal and non-optimal models of resource-extracting economies. This suggests that the change in social welfare is over-estimated when the change in total resource asset value is used as the measure of depletion. A simple empirical exercise, using World Bank data on ‘adjusted net saving’, reinforces the results from theory.     

Natural Resources and Missing Inputs in International Productivity Comparisons*

Standard theory for cross-country productivity comparisons assumes all countries use the same factor inputs in production. This assumption is violated when including natural resources, such as oil, gas and gold, because countries do not extract the full set of resources. In this paper we propose a solution by viewing it as a “missing goods” problem and assigning missing inputs a reservation price equal to the world resource price. We show that this has a substantial impact on relative productivity levels for countries heavily reliant on natural resources for generating their income. Under our new productivity measure, resource-rich countries are no longer uncommonly productive.     

国际贸易和自然资源"诅咒":中国的增长威胁到东南亚地区的发展了吗?

随着中国经济的迅猛发展和快速融入全球市场,东南亚资源丰裕国家正在不断丧失其在劳动密集型制造业上的比较优势,同时其资源开发变得更为有利可图.对这些东南亚国家,尤其是一些最为贫穷同时却又正处于减少中央对资源控制管理的分权过程中的国家而言,这一趋势如何影响长期增长和福利?正如"自然资源诅咒"所预言一样,快速的资源采伐和减速的工业发展可能会使这些国家进入慢速经济增长时期.
