current publication lags in economics journals phe economics profession depends to a large degree upon its scholarly journals to disseminate the results and applications of its recently completed research the journal of economic literature is in fact evidence of that dependence much of the contents of each issue is devoted to an indexing of the current articles to facilitate both access to primary sources and quick cross referencing with related material but how recent are the results reported in the current literature how long does it usually take for a piece of research to evolve from a submitted manuscript to a published article to my knowledge only one study has confronted this question directly and it was published nearly 15 years ago in that study robert coe and irwin weinstock 1967 p 40 reported an average lag between submission and publication of 250 days 8 2 months for articles published in 1966 what has happened since there are no formal surveys to support the suspicion but there is evidence to suggest that the lags have actually increased some journals have begun to charge submission fees ostensibly to reduce the number of manuscripts they must review a plethora of specialized journals have emerged to provide new outlets for specialized papers and to relieve some of the burden from the traditional journals of more general scope one new journal economics letters has been founded completely in response to the lag problem it publishes short papers as quickly as possible in an effort to distribute at least the thrust of current research without a prolonged waiting period all of these responses to long lags lead to one question how severe are the current lags between submission and publication this brief note will report on the results of a survey that can begin to assess the current magnitude of the lag problem the major components of that problem and the success of the various efforts to alleviate it information about the lags involved in the 40 most recently published articles in each journal was solicited from the editors of 66 journals whose contents are routinely recorded in the jel twenty editors responded directly to the request and their reports formed the foundation of this study seven other journals were also in

political instability corruption and policy formation the case of environmental policy abstract this paper develops a theory of environmental policy formation taking into consideration the degree of corruptibility and political turbulence the predictions that emerge are that the interaction between the two variables is important political instability has a negative effect on the stringency of environmental regulations if the level of corruption is low but a positive effect when the degree of corruption is high corruption reduces the stringency of environmental regulations but the effect disappears as political instability increases the empirical findings are fully consistent with the predictions of the model

nature reserves as a bioeconomic management tool a simplified modelling approach this paper demonstrates analytically how a nature reserve may protect the total population realize maximum sustainable yield msy and economic yield ey and how this depends on biological growth migration reserve size and economic parameters the pre reserve population is assumed to follow the logistic growth law and two post reserve growth models are discussed to explore the importance of model assumptions for assessment of reserves the post reserve growth has either a common carrying capacity as in the pre reserve case or each sub population has its own carrying capacity proportionate to its distribution area a combined model as a continuum of the two models is also formulated and briefly discussed population protection against extinction is assured against low cost harvesting including zero cost when relative reserve size is greater than relative migration reserve size may be tuned to realize msy in one model but not in the other economic yield is generally greater in the former but maximum ey cannot be realized in any one

corruption trade and resource conversion abstract recent evidence suggests that special interest groups significantly affect tropical deforestation through lobbying we develop an open economy model in which resource conversion is determined by a self interested government that is susceptible to the influences of the political contributions it receives from the profit maximizing economic agent responsible for land conversion we investigate the effects of lobbying on the cumulative level of resource conversion and examine how trade policy influences the distortions created by political corruption we derive testable predictions that are analyzed through a panel analysis of cumulative agricultural land expansion over 1960 99 for low and middle income tropical countries our findings suggest that increased corruption and resource dependency directly promote land conversion whereas rising terms of trade reduce conversion

guidelines for exploiting natural resource wealth the principles of how best to manage the various components of national wealth are outlined where the permanent income hypothesis the hotelling rule and the hartwick rule play a prominent role as far as managing natural resource wealth is concerned a case is made to use an intergenerational sovereign wealth fund to smooth consumption across generations a liquidity fund for the precautionary buffers to deal with commodity price volatility and an investment fund to park part of the windfall until the country is ready to absorb extra spending on domestic investment capital scarcity implies that a positive part of the windfall should be spent on domestic investment the conclusions highlight the political economy problems that will have to be tackled with these normative proposals for managing wealth the author 2014 published by oxford university press

the concept of natural capital the natural environment is now commonly viewed as a form of capital asset or natural capital also included are ecosystems that provide important goods and services to the economy managing natural capital has consequences for sustainable development however there are contrasting weak versus strong sustainability views which in turn have implications for green accounting natural resource based sovereign wealth funds have emerged as key financial instruments for compensating resource depreciation with greater economy wide investments recent scientific evidence recommends demarcating safe operating spaces to limit exploitation of critical global biophysical subsystems or processes these challenges suggest that the concept of natural capital is pivotal to sound policy

citations in economics measurement uses and impacts i describe and compare sources of data on citations in economics and the statistics derived from them constructing data sets of the post publication citation histories of articles published in the top five journals in the 1970s and 2000s i examine distributions and life cycles of citations compare citation histories of articles in different subspecialties in economics and present evidence on the history and heterogeneity of those journals impacts and the marginal citation productivity of additional coauthors i use a new data set of the lifetime citation histories of over 1 000 economists from thirty universities to rank economics departments by various measures and demonstrate the importance of intra and interdepartmental heterogeneity in productivity throughout the discussion summarizes earlier work including the impacts of citations on salaries and nonmonetary rewards and how citations reflect judgments about research quality in economics and the importance of economic ideas

environmental depletion governance and conflict t he link between natural resource dependence and internal conflict has been approached from a variety of angles in a large and growing interdisciplinary literature while there is an expanding consensus as to what matters the most for such intra state violence episodes the feasibility discontent dichotomy still appears to characterize a disciplinary divide between economists and political scientists this paper attempts to help bridge the gap by allowing for both intrinsic and extrinsic motivations of potential rebels simple non cooperative bargaining yields a nonlinear impact of regulatory quality on the likelihood of conflict and shows that corruption and resource depletion jointly affect the outcome the empirical analysis that follows looks at the effect of environmental depletion and government corruption on the emergence of civil conflicts using a large panel dataset resource depletion the quality of governance and their interaction are found to be significant determinants of civil conflict incidence results are robust to several steps taken to address potential endogeneity concerns

the curse of natural resources in fractionalized countries abstract this paper develops a model that can explain why natural resources are a blessing for some countries but a curse for others in this model natural resources cause fighting activities between rivalling groups fighting reduces productive activities and weakens property rights making productive activities even less attractive the aggregate production decrease exceeds the natural resources direct positive income effect if and only if the number of rivalling groups is sufficiently large the model thus predicts that natural resources lower incomes in fractionalized countries but increase incomes in homogenous countries empirical evidence supporting this prediction is provided

wealth and sustainability for economists in 1974 it was a live question whether the exhaustion of natural resources such as oil would necessarily lead to the decline of economic activity solow showed that constant levels of consumption could be sustained in the face of exhaustibility if there is sufficient substitutability between produced and natural factors of production hartwick then proved that underpinning this result is a saving rule set investment in produced capital equal to the value of resource depletion at each point in time a large literature has shown that a comprehensive measure of the change in real wealth net saving plays a central role in determining whether current well being can be sustained in particular current declines in real wealth signal that future well being will also decline a result that has been confirmed empirically using data for developing countries changes in wealth and sustainability are therefore joined at the hip the current composition of wealth serves to define the policy challenges that countries face in achieving sustainable development if substitution possibilities are limited between natural and other factors of production as one might expect then technical progress is a necessary complement to policies for sustainability

uncertainty measures for economics journal impact factors academic economists appear to be intensely interested in rankings of journals institutions and individuals yet there is little discussion of the uncertainty associated with these rankings to illustrate the uncertainty associated with citations based rankings i compute the standard error of the impact factor for all economics journals with a five year impact factor in the 2011 journal citations report i use these to derive confidence intervals for the impact factors as well as ranges of possible rank for a subset of thirty journals i find that the impact factors of the top two journals are well defined and set these journals apart in a clearly defined group an elite group of 9 11 mainstream journals can also be fairly reliably distinguished the four bottom ranked journals are also fairly clearly set apart for the remainder of the distribution confidence intervals overlap and rankings are quite uncertain jel a14

savings growth and the path of utility we derive an expression relating the change in instantaneous utility to the growth of net genuine saving in an economy with multiple stocks and externalities that maxi mizes welfare in the utilitarian sense this result is then shown to hold for decentralized competitive efficient economies as well to yield an extension of the hartwick rule instan taneous utility is non declining along a development path if genuine saving is decreasing by way of example the rule is applied as a constant genuine saving rate rule in a simple dasgupta heal solow stiglitzeconomy the rule yields a path with unbounded consump tion and higher wealth than on the standard hartwick constant consumption path jel classification q01 q56 o13

on the endogeneity of resource comanagement theory and evidence from indonesia we examine theoretically the emergence of participatory comanagement agreements that share between state and user the management of resources and the benefits from use going beyond user user interactions our state user model addresses a critical question when will comanagement arise in order to consider the right baseline for evaluating comanagement s forest and welfare impacts we then compare our model s hypotheses concerning de facto rights negotiated agreements and transfers all endogenous with community level data including observed agreements in a protected indonesian forest these unique data could refute the model despite being limited but instead offer support

technology change as a policy response to promote changes in land management for environmental benefits a previous study developed a framework for choosing among groups of policy mechanisms for encouraging environmentally beneficial land use change the framework highlights that these choices should depend on the relative levels of private or internal net benefits and public or external net benefits incentive based mechanisms polluter pays and or beneficiary pays and extension need to be targeted carefully to appropriate projects where private net benefits are close to zero and or public net benefits are more extremely positive or negative this article focuses on policy mechanisms that alter the net benefits of changing land management including r d to develop new technologies and training to improve the skill of landholders at using existing technologies these policy options are now treated more comprehensively within the public benefits private benefits framework benefits of technology change projects can include reductions in the opportunity cost of compliance with environmental programs increases in the public benefits of a particular type of land use change or improvements in private net benefits resulting in public benefits through greater or more rapid adoption by private landholders from an environmental management perspective technology development is most relevant where public net benefits of land use change are positive and private net benefits are negative but not highly negative there is a set of projects for which technology change is the only viable alternative to no action highlighting the importance of technology change in these cases

one sided sustainability tests with amenities and changes in technology trade and population abstract if an economy with multiple consumption goods including environmental amenities uniquely maximises present value with constant discounting it is unsustainable at some time if either of two measures augmented net investment or the change in augmented green net national product are zero or negative then augmented denotes that time is treated as a productive stock which includes in each measure the value of future exogenous changes in technology or terms of trade adjustments are found to make each measure a test for individual sustainability when population grows exogenously the practical and philosophical rationale for testing sustainability in a present value maximising and therefore fully prescribed development path is discussed

trade tropical deforestation and policy interventions trade interventions are increasingly advocated as a means for controlling timber related tropical deforestation this paper analyzes the impact on deforestation of such policy instruments in a dynamic framework the forest is modelled as a potentially renewable resource and timber is extracted for purposes of export and domestic consumption optimality conditions for a variety of model specifications are derived and the impacts of changes in the terms of trade and market structure on long run deforestation are analyzed the results of this analysis suggest that trade interventions that seek to affect the terms of trade against the export of tropical timber products are in the long run a second best policy option for influencing the deforestation process

how do journal quality co authorship and author order affect agricultural economists salaries utilizing an original data set containing annual salaries and peer reviewed publication histories for 326 faculty members from top ranked ph d granting programs we examine the labor market for academic agricultural economists the results suggest that higher quality publications have a greater impact on annual earnings that sole authored articles have a higher return than multi authored articles and that no wage premium exists for being the lead author of a non alphabetic article

reputation and earnings the roles of quality and quantity in academe we examine the determinants of professional reputation does quantity of exposures raise reputation independent of quality does quality of the most important exposure have extra effects on reputation in a very large sample of academic economists there is little evidence that a scholar s most influential work provides any extra enhancement of reputation quality rankings matter more than absolute quality quantity has a zero or even negative effect on proxies for reputation data on salaries however show positive effects of quantity independent of quality we test explanations for the differences between the determinants of reputation and salary jel l14 j31

context dependent biodiversity conservation management regimes theory and simulations ecosystem degradation hasmotivated a search for successful conservation approaches the perceived failure of state directed protected areas in the tropics has prompted experimentation with community management and co management strategies numerous case studies suggest that none of these are effective universally there exists however little analytical or empirical work to identify under what conditions one arrangement will be more effective than another this paper develops a model of statedependent equilibrium conservation management design that identifies the comparative advantage of different managers in the interest of appropriately locating authority for conservation tasks as a function of prevailing biophysical economic and sociopolitical conditions

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

an examination of the influence of theory and individual theorists on empirical research in microeconomics most economists would concur that an important role of economic theory is to influence the direction of empirical research either by posing new questions or by suggesting new answers to old questions whether or not modem theory should be judged to be a success on that metric is a frequently debated question but one on which there has been little systematic investigation in this paper we provide some preliminary empirical evidence on the extent to which various fields of economic theory as well as specific theorists have succeeded in influencing the path followed by empirical research in the area of microeconomics based on our analysis of all empirical microeconomics papers published in three leading journals over a three year period we arrive at a number of conclusions concerning the impact of theory on empirical research our first finding is that the set of theory papers cited as the primary motivation for leading empirical work is surprisingly dispersed very few individual works of theory seem to have exerted a great influence in the 149 empirical papers we consider one author gary becker is cited 15 times but no other author is cited more than 10 times no single paper is cited more than five times a second finding is that empirical researchers behave as if they are heavily influenced by recent theoretical contributions among the theory pa

net national product as an indicator of sustainability net national product nnp can potentially serve several objectives among others to measure value added and to be an indicator of welfare in the aftermath of the world commission on environment and development however it also seems important to investigate whether the concept of nnp can serve as an indicator of sustainability my point of departure following hicks 1946 ch 14 is therefore to require that nnp should measure what can be consumed in the present period without reducing future consumption possibilities and in line with this to argue that the nnp should equal the maximum per capita consumption level that can be sustained if sufficiently many facilitating assumptions are made then a concept of nnp that serves as an exact indicator of sustainability can easily be constructed for instance for a closed economy with a constant population a stationary technology and with only one capital good it follows that the present does not reduce future consumption possibilities if and only if it does not decrease the stock of the single capital good hence under the assumption that the one capital good k is identical to the one consumption good x nnp defined as y x k measures the maximal sustainable consumption at time t because then x y is equivalent to k the purpose of this note is to establish that with multiple capital goods it is not in general possible to construct an exact indicator of sustainability on the

public benefits private benefits and policy mechanism choice for land use change for environmental benefits the choice of policy mechanisms for encouraging environmentally beneficial land use change should depend on the relative levels of private or internal net benefits and public or external net benefits a map of recommended policy mechanisms is developed depending on the relative levels of these variables positive incentives negative incentives and extension need to be targeted carefully to appropriate projects where private net benefits are closer to zero and or public net benefits are more extremely positive or negative technology development is suggested where private net costs outweigh public net benefits no action is recommended for many potential projects

human capital tangible wealth and the intangible capital residual since income is the return on wealth the total wealth of any given country should be on the order of 20 times its gdp instead the average observed ratio from the balance sheet accounts of the system of national accounts sna is a factor of 2 6 to 6 6 depending on whether natural resource stocks are included in the balance sheet the clear implication is that the sna wealth accounts are incomplete with the most obvious omission being human capital estimating the value of human capital using the lifetime income approach for a sample of thirteen mostly high income countries yields a mean share of human capital in total wealth of 62 four times the value of produced capital and 15 times the value of natural capital but for selected high income countries in the sample there is still an average of 25 of total wealth which is unaccounted it is neither produced nor natural nor human capital this residual intangible wealth is arguably the stock equivalent of total factor productivity the value of assets such as institutional quality and social capital which augment the capacity of produced natural and human capital to support a stream of consumption into the future

capital theory and the measurement of sustainable development an indicator of weak sustainability the measurement of sustainable development is not without considerable difficulties yet this should not detract from the positive advances that can be made in this direction in this paper we present one form that a weak sustainability indicator can take derived from a simple but intuitive savings rule it incorporates the idea that the level of overall capital stock should be non decreasing although subject to qualification at this stage some interesting results emerge from the application of the rule to 18 countries

an examination of the reliability of prestigious scholarly journals evidence and implications for decision makers in universities all over the world hiring and promotion committees regularly hear the argument this is important work because it is about to appear in prestigious journal x moreover those who allocate levels of research funding such as in the multi billion pound research assessment exercise in uk universities often come under pressure to assess research quality in a mechanical way by using journal prestige ratings this paper s results suggest that such tendencies are dangerous it uses total citations over a quarter of a century as the criterion the paper finds that it is far better to publish the best article in an issue of a medium quality journal like the oxford bulletin of economics and statistics than to publish the worst article or often the worst 4 articles in an issue of a top journal like the american economic review implications are discussed

differences in citation patterns across journal tiers the case of economics we study how citation patterns differ between journal tiers in economics concretely we analyze citations patterns of more than 6 000 economics research articles published in top five second tier and top field economics journals between 1992 and 1996 in line with previous literature we find that top five journals articles generally receive more citations and that the life cycles of those citations are longer however their influence in term of citations is overestimated in its first twenty five years since publication the median top five article accumulates 4 25 around 3 as many citations when compared to the second tier and top field median article we show that this ratio is strongly associated with the field of economics research e g this ratio is the lowest for econometric methods papers and with articles impact e g in all fields of economics research except for theory this ratio decreases sharply as one moves toward high impact articles in term of citations

constant savings rates and quasi arithmetic population growth under exhaustible resource constraints in the dasgupta heal solow stiglitz dhss model of capital accumulation and resource depletion we show the following equivalence if an efficient path has constant gross and net of population growth savings rates then population growth must be quasi arithmetic and the path is a maximin or a classical utilitarian optimum conversely if a path is optimal according to maximin or classical utilitarianism with constant elasticity of marginal utility under quasi arithmetic population growth then the gross and net of population growth savings rates converge asymptotically to constants

taking natural capital seriously the paper sets out a pragmatic case for preserving the aggregate level of natural capital in the face of the declines in biodiversity and the rising population and major increases in consumption that economic growth will bring in this century the accounting framework to achieving this objective is considered focused on the role of asset registers particular attention is paid to renewable assets at risk of falling below critical thresholds these assets are key components of the balance sheet capital maintenance expenditures are required to maintain the value of assets intact since renewable natural assets should not be depreciated but rather treated as assets in perpetuity within the aggregate substitutions with other forms of capital are permitted but only if there is compensation for any detriment to natural capital offsetting is one mechanism for achieving this compensation the case for enhancing the aggregate is considered and the paper shows how a broader national plan over a generation could contribute to the policy objective of leaving the next generation with a richer endowment of natural capital the policy instruments for embedding natural capital into public policy are reviewed

comprehensive wealth and future consumption accounting for population growth economic theory predicts that the current change in national wealth broadly defined to include natural and human capital as well as produced capital genuine savings determines whether the present value of future changes in consumption is positive or negative theoretical research has focused on the effects of population growth on this relation but no rigorous empirical investigation has been conducted panel data for 64 developing countries during 1970 82 are used to test the effects of three adjustments for population growth including one that controls for omitted wealth although the adjustments have substantial impacts on estimates of genuine savings they lead to only limited improvements in the relation between those estimates and subsequent consumption changes even without adjustments for population growth adjustments for natural resource depletion improve the relation significantly policymakers and economists can interpret published estimates of genuine savings as signals of future consumption paths if and only if the estimates include adjustments for natural resource depletion but better estimates of capital stocks are needed before it can be confidently said that adjustments for population growth significantly improve the accuracy of those signals

sustaining wealth simulating a sovereign wealth fund for the uk s oil and gas resources past and future abstract exhaustible resources and the revenues they generate present a number of broad problems for macroeconomic management for example tax revenues can be large and highly volatile and the stream of revenues is finite an increasing number of countries now view resource funds and or fiscal rules for resource revenues as the answer to these challenges in this paper we explore the consequences for the uk if past revenues arising from the depletion of subsoil assets had been channelled into a sovereign wealth fund we show that had a decision been made to establish such a fund in 1975 this could have been substantial in size by 2018 about gbp 354 billion and moreover would have had a number of benefits such as a reduction in volatility of resource revenues flowing to the treasury crucially the fund s value would have substantially boosted the size of the government balance sheet yielding corresponding fiscal benefits we argue this missed opportunity is underlined further by considering the current debate about shale gas development in the uk notwithstanding considerable uncertainties favourable and optimistic projections for key parameters are required for any shale based fund to match what we simulate based on past experience for conventional subsoil assets

the slowdown of the economics publishing process over the last three decades there has been a dramatic slowdown of the publication process at top economics journals a substantial part is due to journals requiring more extensive revisions various explanations are considered democratization of the review process increases in the complexity of papers growth of the profession and cost and benefit arguments changes in the profession are examined using time series data connections between these changes and the slowdown are examined using paper level data there is evidence for some explanations but most of the slowdown remains unexplained changes may reflect evolving social norms

rationalist explanations for war realist and other scholars commonly hold that rationally led states can and sometimes do fight when no peaceful bargains exist that both would prefer to war against this view i show that under very broad conditions there will exist negotiated settlements that genuinely rational states would mutually prefer to a risky and costly fight popular rationalist and realist explanations for war fail either to address or to explain adequately what would prevent leaders from locating a less costly bargain essentially just two mechanisms can resolve this puzzle on strictly rationalist terms the first turns on the fact that states have both private information about capabilities and resolve and the incentive to misrepresent it the second turns on the fact that in specific strategic contexts states may be unable credibly to commit to uphold a mutually preferable bargain historical examples suggest that both mechanisms are empirically plausible

environmental regulations transfers and trade theory and evidence abstract this paper develops a theory of compensation of producers for the costs associated with environmental regulations we show that the existence of transfers can give counter intuitive effects of environmental policy on both output and trade flows in particular the compensation obtained by producers neutralizes the effect of environmental policy on output and consequently on trade flows this may help explain why previous empirical research has found weak evidence that environmental regulations affect trade patterns the theory is tested using agricultural sector data the evidence supports the hypothesis that environmental regulations and transfers are positively correlated

spatial aggregation and the value of natural capital abstract location matters for the value of capital assets the value of changes in natural capital wealth can depend on whether natural capital asset prices are measured locally and then aggregated or whether average values are applied over aggregate representative areas spatial heterogeneity of resource characteristics and institutions impact approximations of the intertemporal welfare function and accounting price function because when spatial aggregation precedes valuation it implies greater arbitrage opportunities leading to more inelastic shadow accounting price functions than when valuation is done locally and then aggregated aggregation of observed values across varying resource and institutional characteristics can lead to omitted variables bias we illustrate these results in the context of groundwater in the kansas high plains aquifer and demonstrate that the accounting price function is less elastic when the accounting price is measured locally failure to measure locally and then aggregate could lead to undervaluing scarce resources and overvaluing plentiful ones which biases wealth accounts in favor of passing the non declining wealth sustainability test

is there value added from the review process in economics preliminary evidence from authors do referees employed by journals merely screen acceptable from unacceptable manuscripts or are they charged with an additional value adding responsibility vis a vis the papers they review drawing from editorial correspondence provided by survey respondents i address this question by examining the relationship between citations of published papers and comments provided by reviewers and editors referees comments demonstrate a positive impact on subsequent citation of papers while comments made by editors show no such impact value adding by editors appears to derive principally from efficient matching of papers with reviewers

which journal rankings best explain academic salaries evidence from the university of california the ranking of an academic journal is important to authors universities journal publishers and research funders rankings are gaining prominence as countries adopt regular research assessment exercises that especially reward publication in high impact journals yet even within a rankings oriented discipline like economics there is no agreement on how aggressively lower ranked journals are down weighted and in how wide is the universe of journals considered moreover since it is typically less costly for authors to cite superfluous references whether of their own volition or prompted by editors than it is to ignore relevant ones rankings based on citations may be easily manipulated in contrast when the merits of publication in one journal or another are debated during hiring promotion and salary decisions the evaluators are choosing over actions with costly consequences we therefore look to the academic labor market using data on economists in the university of california system to relate their lifetime publications in 700 different academic journals to salary we test amongst various sets of journal rankings and publication discount rates to see which are most congruent with the returns implied by the academic labor market jel a14 i23 j44

the political economy of wildlife exploitation in this paper we analyze the exploitation of wildlife in a third world context in the model there are two agents an agency managing a habitat area of fixed size and a group of peasants the agency managing the habitat area has the legal right to exploit the wildlife while the local people hunt illegally introducing the concept of relative harvesting dominance we demonstrate that the stock utilization depends crucially on the prevailing economic and ecological conditions it is also shown that the existing property rights regime appears in different forms depending on these conditions

green growth degrowth and the commons the concepts of green growth and degrowth occupy central positions in the public debate on the relationship between economic growth and the environment while proponents of the former approach claim that environmental measures can promote growth by for example more efficient use of natural resources proponents of the latter maintain that environmental integrity can only be upheld by slowing down growth this paper argues that both approaches constitute inadequate foundations for public policy as they fail to appropriately conceptualize social welfare we show how policy aimed at social welfare can be understood as managing a portfolio of capital stocks some of which exhibit the characteristics of commons i e common pool resources and public goods we then propose a programme of welfare diagnostics which aims at establishing minimum thresholds for capital stocks essential to welfare as a guide for real world policy formulation and discuss the role of appropriation of natural resource rents for its practical implementation we conclude by highlighting the central role of scientific policy advice in determining how different conceptions of welfare would be reflected in setting targets and choosing the means to achieve them

resource depletion and sustainability in small open economies abstract exogenous price changes affect the amount that a small country exporting natural resource commodities must invest to sustain its consumption level the necessary amount is given by the difference between hotelling rent and the discounted sum of future terms of trade effects capital gains the latter term is found to be large relative to the former in the case of petroleum depletion in indonesia this suggests that resource rich countries will need to invest more than previously expected to sustain their consumption levels if natural resource prices continue their long term historical decline

green growth an assessment green growth is almost tautologically required for global welfare to rise in the long run economic growth is desirable not least because over 1 billion people still live in conditions of poverty undermining the ecological basis for human civilization will damage human welfare and further undermine economic growth there are large adverse environmental externalities from economic activity that affect human welfare directly and indirectly through lower measured output finding ways to tackle these externalities will enhance wellbeing and allow continued growth of gdp while preserving aggregate natural capital however achieving this goal presents societies with major challenges the composition of gdp is likely to have to change significantly with more emphasis on new ideas and less on increased material throughputs the role of the state in a green growth transition will have to go beyond internalizing externalities to get prices right the necessary transformation will be large system wide and structural so the state must also provide at the least overall strategic direction innovation will be central to any successful strategy as will be dealing with the distributional consequences of stronger environmental policies particularly in developing countries organizing the appropriate collective action at the right levels in the face of inadequate information while ensuring that the appropriate governance arrangements are in place will not be easy policy experimentation is needed with more rigorous ex post evaluation and where successful rapid dissemination of the results

on the welfare significance of green accounting as taught by parable abstract green nnp is a national accounting concept that subtracts off from gnp not just depreciation of capital but also depletion of environmental assets for a time autonomous technology green nnp has a rigorous welfare interpretation as an exact measure of the economy s future power to consume the present paper extends the standard framework to cover the case of labor augmenting technological progress for this special case of time dependence a powerful conceptual parable applies it is as if the conclusion from a simple minded welfare story told by the standard neoclassical one sector growth model covers a far more general situation involving any number of different types of capital any convex production possibilities set and fully optimizing behavior implications and applications are discussed

undergraduate econometrics instruction through our classes darkly the past half century has seen economic research become increasingly empirical while the nature of empirical economic research has also changed in the 1960s and 1970s an empirical economist s typical mission was to explain economic variables like wages or gdp growth applied econometrics has since evolved to prioritize the estimation of specific causal effects and empirical policy analysis over general models of outcome determination yet econometric instruction remains mostly abstract focusing on the search for true models and technical concerns associated with classical regression assumptions questions of research design and causality still take a back seat in the classroom in spite of having risen to the top of the modern empirical agenda this essay traces the divergent development of econometric teaching and empirical practice arguing for a pedagogical paradigm shift

hartwick s rule in open economies to sustain constant consumption the hartwick rule prescribes reinvesting all resource rents in reproducible capital this paper shows that the rule does not apply to open economies since the underlying stationary technology assumption is violated when gains from trade are taken into account a correct analog to the hartwick rule for open economies is developed and applied to a model of capital accumulation and resource depletion la regle de hartwick dans les e conomies ouvertes pour maintenir la consommation constante la regle de hartwick prescrit qu il faut reinvestir toutes les rentes des ressources dans du capital reproductible ce me moire montre que la regle ne s applique pas dans le cas d economies ouvertes parce que le postulat d une technologie stationnaire n9est pas satisfait quand on tient compte des gains engendres par le commerce international l auteur developpe une version correcte pour les economies ouvertes dans 1 esprit de la regle de hartwick et l applique a un modele d accumulation de capital et d epuisement des ressources

the inclusive wealth index a critical appraisal abstract among recent high profile propositions to revise national accounts and to provide new indicators of sustainability and well being the inclusive wealth framework and the related inclusive wealth index iwi undoubtedly stand out as one of the most promising endeavours built up at the confluence of welfare development and sustainability economics the indicator has been designed to bring information about the wealth of nations and their sustainability in a comprehensive way the inclusive wealth framework is nevertheless fraught with limitations due to questionable theoretical assumptions gaps in data availability unrealistic assumptions about the future and inability to account for distributional issues we propose a non exhaustive critical appraisal of the index and its underlying framework we conclude that these limitations undermine its capacity to fulfil the requirements of a satisfactory sustainability indicator we argue that most problems lie in the substantial discrepancy between the inclusive ambition of the indicator and the scarce means to implement it whereas the interconnectedness of the various assets that constitute wealth as well as their complex evolution through time are acknowledged by the proponents of inclusive wealth the way the iwi is computed is rather a mere addition of layers of actuarial like monetary values for a not inclusive yet range of capital assets caution is thus warranted while using such an approach and shorter range alternatives to pursue similar goals are proposed

investing exhaustible resource rents and the path of consumption we set out dollar valued net national product for an economy with a wasting essential stock oil deposit we take up maintaining capital intact and locally unchan ging consumption the percentage change in net investment or genuine savings relative to the market rate of interest denotes whether current consumption is rising

choices and the value of natural capital sustainability requires maintaining opportunities for future generations so they can meet their needs opportunities are passed to future generations through a set of capital assets nature provides an important class of these assets but markets seldom reveal the marginal value of natural capital rather the marginal social worth or asset price must be imputed based on intertemporal exchange in the context of assessing whether intertemporal allocation rules lead to sustainable development appropriate asset prices must be based on the actual allocations and trade offs society makes therefore measuring economic programmes that enable the measurement of asset prices is an important empirical task we review the theory of measuring natural capital asset prices and discuss the key elements of measuring economic programmes that enable the measurement of natural capital asset prices we place the measurement of economic programmes and natural capital asset prices in the context of wealth based sustainability metrics
