unequal vulnerability to climate change and the transmission of adverse effects through international trade in this paper we consider the unequal distribution of climate change damages in the world and we examine how the underlying costs can spread from a vulnerable to a non vulnerable country through international trade to focus on such indirect effects we treat this topic in a north south trade overlapping generations model in which the south is vulnerable to the damages entailed by global pollution while the north is not we show that the impact of climate change in the south can be a source of welfare loss for northern consumers in both the short and the long run in the long run an increase in the south s vulnerability can reduce the welfare in the north economy even in the case in which it improves its terms of trade in the short run the south s vulnerability can also represent a source of intergenerational inequity in the north therefore we emphasize the strong economic incentives for non vulnerable and a fortiori less vulnerable economies to reduce the climate change damages on more vulnerable countries

building the family nest premarital investments marriage markets and spousal allocations we develop a model of the household in which spousal incomes are determined by premarital investments the marriage market is characterized by assortative matching and endogenously determined sharing rules form the basis of intra household allocations by incorporating pre marital investments and spousal matching into the collective household model we are able to identify the fundamental determinants of endogenously determined and maritally sustainable intra marital sharing rules in particular we find that all sharing rules along the assortative order support unconditionally efficient outcomes where both pre marital investments and intra household allocations are efficient the efficiency of both pre marital choices and household allocations then enables us to show that for each couple the marriage market generates a unique and maritally sustainable sharing rule that is a function of the distribution of pre marital endowments and the sex ratios in the market

interrupted work careers depreciation and restoration of human capital the quantitative effects and even the existence of a human capital depreciation phenomenon have been a subject of controversy in the recent literature prior work however was largely cross sectional and the longitudinal dimension if any was retrospective using longitudinal panel data on married women in nls we have now established that real wages at reentry are indeed lower than at the point of labor force withdrawal and the decline in wages is greater the longer the interruption another striking finding is a relatively rapid growth in wages after the return to work this rapid growth appears to reflect the restoration or repair of previously eroded human capital the phenomenon of depreciation and restoration is also visible in data for immigrants to the united states however while immigrants eventually catch up with and often surpass natives returnees from the nonmarket do not fully restore their earnings potential

human capital formation and local economic performance bradley s and taylor j 1996 human capital formation and local economic performance reg studies 30 1 14 this paper is concerned with the interaction between the vocational education and training system vet and local economic performance in britain after briefly discussing the shortcomings of britain s vet system the paper examines the way in which the education and training system and the local economy interact in particular it is argued that the outputs from the local education and training system determine and are determined by the locality s stock of high skill workers these high skill workers in turn help to determine the competitiveness and hence the economic performance of the local economy this has feedback effects on the stock of high skill workers through its effect on the occupational mix of in migrants some empirical tests of the model are provided based on data relating to 107 local education authority areas in england bradley s et taylor j 1996 la formation du capi

does family income matter for schooling outcomes using adoptees as a natural experiment one would expect that family income is an important positive factor in children s school attainment however evidence is often tainted by the lack of control for parental ability since at least a portion of ability is transferred genetically to children this paper uses a sample of adopted children and offers genetically unbiased estimates we further correct for biases arising from unobserved parenting qualities and from parents differentiation between their own birth and adopted children family income still has a significant effect it implies that high ability children in low income families face binding credit constraints that society may wish to relieve

rotating and accumulating savings and credit associations a development perspective abstract financial self help groups in low income countries consist of two basic types rotating and accumulating savings and credit associations or roscas and ascras in the ascra funds are not immediately withdrawn but are left to grow for loan making comparing the two groups the author finds similarities and differences efforts to rectify the rosca s shortcomings have prompted many innovations and given birth to a hybrid preserving the best of both types in constant adaptation to changing environments

the sustainable borders of the state economic crises have historically set the stage for the reconfiguration of the economic borders of the state current concerns focus on debt and associated intergenerational issues such as pensions infrastructure and the environment the sustainable state is designed to put in place a framework for integrating these intergenerational issues alongside the traditional focus on macroeconomic policy static market failures and transfers the building blocks include the accounting framework and in particular a national balance sheet setting out assets and liabilities and providing for capital maintenance over time to support these assets and to provide for sufficient investment the sustainable state requires an appropriate level of savings and institutions to translate these savings into investments two components are the deployment of regulatory asset bases to underpin long term sunk and fixed costs given the time inconsistency problem in government s commitments and the development of financial intermediaries such as an infrastructure bank copyright 2011 oxford university press

unemployment and early school leaving theoretical predictions about the effect of unemployment on school leaving are ambiguous unemployment might affect the decision to leave school in a number of different ways i current youth unemployment a higher probability of current unemployment for those who choose to leave school would tend to discourage early school leaving first by reducing the expected gains from job search a discouraged worker effect and second by reducing the opportunity cost of additional education ii expected future unemployment the theoretical predictions here are less clear cut an increase in the probability of future unemployment that affected both those with and without additional education would tend to reduce the rate of return to education and hence education demand on the other hand those with more education may be less affected by rises in unemployment and this may encourage further schooling these two opposing effects have been formalised as a shift and a tilt in the unemployment probability schooling relationship kodde i988 fig i suggests that in the united kingdom both effects could have accompanied the transition from the late 1970s to the i98o the full effects of uncertainty on education investment in a two period model depend on the correlation between the uncertainty in the two periods levhari and weiss 1974 how current unemployment rates are used to form expectations of future unemployment is clearly an important issue here also some individuals may be able to undertake job search before committing themselves to leave school and whilst affected by the risk of future unemployment may be comparatively unaffected by the risk of current unemployment iii effects ofparental unemployment parents unemployment in general reduces family income their children s educational demand may fall as a consequence for three reasons first the consumption demand for education will be lower second a reduction in the first period income reduces the investment demand for education assuming decreasing absolute risk aversion kodde i 988

environmental tax policy and intergenerational distribution abstract we study the effects of environmental taxation within the context of an overlapping generations model the quality of the environment is modelled as a durable consumption good introduction of the environmental tax harms old existing generations and benefits young existing generations as well as all future generations increasing the tax in a pareto improving manner is easier the higher the pre existing tax the reverse holds if tax policy is decided by majority rule a suitably designed bond policy can be used to redistribute the efficiency gains due to the internalisation of environmental externalities across the generations

degradation of environmental capital and national accounting procedures abstract the capital theoretic approach to the environment as a wastable stock a stock with a flow of abatement services is explored in a simple ricardo like model involving wheat production and pollution production as an essential by product we then turn to how the national accounts are implicit in growth or capital theory models and how formulae emerge for accounting for the wasting of environmental capital airsheds and watersheds from excessive use

career interruptions and subsequent earnings a reexamination using swedish data this paper reexamines the link between career interruptions and subsequent wages using a rich new swedish dataset we are able to disaggregate time out of work into several components regressing

optimal tax rules and public sector efficiency with an externality in an overlapping generations model abstract this paper examines optimal tax rules and public sector efficiency integrating them in a second best world with pollution by using an overlapping generations model the second best world is characterized by the comparative statics of green preferences the main results obtained are as follows first the marginal cost of public funds may be reduced by the externalities regardless of the choice of taxes second optimal environmental and non environmental tax rules are additively and directly affected by the dynamic efficiency of capital accumulation per unit labour decal and indirectly by it through the efficiency of the public sector environmental taxes going beyond pigovian ones may be welfare improving if the decal is improved by the environmental tax even optimal non environmental tax rules should additively and directly counter the dynamics of pollution to consider the income effects of the optimal tax system for the future third the additivity property or the principle of targeting does not hold even in the absence of incentive compatibility constraints the essential reasons for this are clarified as follows distortions that should be countered by taxes that is the income effects of the optimal tax system and the decal in this model break the equality between optimal environmental taxes and the externalities measured by governments finally growing environmental concerns may in fact increase pollution the inverse relationship between environmental and labour income taxes may not hold

managing cattle grazing under degraded forests an optimal control approach abstract in this paper aspects of knowledge generation and administration concerning management of a rural enterprise in the argentine chaco region are analyzed the deterioration of natural resources and human living conditions show that forest cattle interaction and the ecological economics of the system are poorly understood or not properly taken into account a methodological solution to a typical decision making problem is proposed here and illustrated by a worked example extracted from a real feasibility study the introduction provides a summary of the natural history and of the human interventions in the region arguments on the roke of silvopastoral systems in reverting forest and soil degradation into sustainable productive undertakings are also exposed the mathematical treatment of the problem follows a system theoretic approach a basic nonlinear model for the dynamics is designed first its simplest version includes three state variables livestock units forest biomass and forage availability and two manipulated variables percentage of female calves sold each year and percentage of the cows that did not give birth during the past period and went for sale states and controls are related by coupled differential difference equations selected results from simulation are shown foundations are also laid for taking into account impulsional controls selective and massive wood extractions forage implantation cattle additions and sales the objective function reflects sustainable development principles it evaluates the process in terms of usual economics and introduces ecological components of the management strategy the total cost is expressed as the accumulation of net expenses made for a fixed number of years minus the sale value of the firm at the end then a dynamic programming scheme is developed for finding optimal trajectories with respect to the basic setup shadow prices for the states are derived from the solution progress towards the building of a decision support system with the preceding elements is reported

second order sustainability conditions for the development of sustainable innovations in a dynamic environment abstract in particular radical innovations can be important means to achieving improved sustainability due to the existence of path dependency and lock in however the transition from one technological trajectory to another more sustainable one is often impeded by significant barriers fortunately these barriers are by their nature subject to substantial changes in time so it makes sense to carefully distinguish between periods of stability showing high barriers in which the given trajectory can hardly be left and periods of instability characterized by low barriers where a new trajectory can be reached more easily the latter distinction matters since sustainable innovations often rely on governmental regulation and the economic burden arising from this regulation will be much lower in periods of instability moreover due to the complexity and dynamics of change in their respective environments innovations are generally associated with fundamental uncertainty such that it becomes impossible to predict the degree of sustainability yielded by specific innovations in the longer run under these circumstances it is essential to facilitate the change between trajectories and to allow for the possibility to select between a variety of alternative trajectories within a process of trial and error sustainability as viewed from this evolutionary perspective is therefore better understood as the general capability to adapt that is to readily change from less to more sustainable technological trajectories since the latter kind of sustainability determines the conditions under which the former kind i e sustainability related to a specific technology can be achieved the two kinds are respectively called second order and first order sustainability finally a series of determinants and corresponding indicators from the techno economic political and socio cultural sphere is identified which after proper measurement and weighting allow for making an assessment whether and when the incumbent industry is sufficiently destabilized and the political system rendered sufficiently favorable to the new more sustainable technology such that a transition to the preferred trajectory is possible without too much effort

linking economic and ecological models for a marine ecosystem increasingly economists and ecologists have begun to recognize the value to public policy of combining information and results from each discipline into multidisciplinary studies here we present a methodological approach that links economic and ecological analyses we develop an economic ecological model by merging an input output model of a coastal economy with a model of a marine food web we describe distinct linear system sub models of the economy and the ecosystem and we develop a method for linking the two our method extends the work of earlier researchers by incorporating an ecosystem matrix into resource multipliers and by showing how these multipliers may be calculated we present a numerical example for the new england region using coastal economic and marine ecological data from the region for a restricted set of industry sectors and food web trophic levels we calculate resource multipliers for the example and we simulate the economic impacts of changes in primary production in the ecosystem on final demands for fishery products the results illustrate the effects of incorporating the impacts of habitat destruction and ecosystem structure on resource multipliers our approach can be extended to incorporate the full range of sectors in the economy and trophic levels in a linked ecosystem 2003 elsevier b v all rights reserved

accounting for the value of ecosystem services abstract a value of ecosystem services ves may be calculated by multiplying a set of ecosystem services by a set of corresponding shadow prices this paper examines the role of the ves concept in measuring trends in human well being under conventional arguments from applied welfare economics standard measures of market consumption may be extended to include the value of direct environmental services which affect welfare in ways that are not mediated by the consumption of purchased goods the ves concept does not capture values such as ecological sustainability and distributional fairness that are not reducible to individual welfare and its operationalization is constrained by the well known limitations of nonmarket valuation methods nonetheless attempts to calculate the value of environmental services can provide insights into the tradeoffs between market activity and environmental quality that are implicit in the process of economic growth such efforts can promote informed debate concerning the achievement of sustainable development

optimal dutch disease growth models of the dutch disease such as those of krugman 1987 matsuyama 1992 sachs and warner 1995 and gylfason et al 1999 explain why resource abundance may reduce growth however the literature also raises a new question if the use of resource wealth hurts productivity growth how should such wealth be optimally managed this question forms the topic of the present paper in which we extend the growth literature on the dutch disease from a positive to a normative setting we show that the assumptions in the previous literature imply that the optimal share of national wealth consumed in each period needs to be adjusted down however some dutch disease is always optimal thus lower growth in resource abundant countries may not be a problem in itself but may be part of an optimal growth path the optimal spending path of the resource wealth may be increasing or decreasing over time and we discuss why this is the case

informal microfinance institutions and development led tourism entrepreneurship this paper explores how informal microfinance institutions imfis support development led tourism entrepreneurship through providing microcredit and development opportunities to small tourism firms stfs as well as undertaking communitarian projects and outreach activities that promote the business activities of stfs drawing on resilience and social capital as central concepts the paper argues that the form of collective action found in imfis can be examined to understand their impact on development led tourism entrepreneurship using cameroon as a case study important policy challenges in destinations where regulatory constrains cause many stfs to become dependent on imfis as opposed to formal regulated financial institutions in development led tourism are highlighted

do recessions keep students in school the impact of youth unemployment on enrolment in post compulsory education in england in this paper i assess the impact of the youth labour market on enrolment in post compulsory education to that end i construct data for a panel of english regions and identify youth labour market effects using variation in youth unemployment rates across regions and over time my estimates suggest that the youth labour market has large enrolment impacts at least twice as large as suggested by uk estimates based on time series data this helps to explain why enrolment growth slowed down from the mid 1990s and suggests that a weakening youth labour market could cause enrolment to increase again

on the intergenerational allocation of natural resources it is known hartwick and others that under standard assumptions a society that invests in reproducible capital the competitive rents on its current extraction of exhaustible resources will enjoy a consumption stream constant in time it is shown here that this result can be interpreted as saying that an appropriately defined stock of capital including the initial endowment of resources is being maintained intact and that consumption can be interpreted as the interest on that patrimony this seems like a useful rule of thumb for policy

the wage expectations of european business and economics students expected earnings and expected returns to education are seen by labor economists as a major determinant of educational attainment in spite of this the empirical knowledge about expectations and their formation is scarce in this paper we report the results of the first systematic study of the wage expectations of european university students our data are based on a uniform questionnaire answered by about 3 000 business and economics university students across europe we study the determinants of wage expectations and expected employment probabilities the variability of these expectations and their variation across countries and universities we also examine the tradeoff between expected starting wages and expected wage growth

intertemporal equity and efficient allocation of resources abstract competitive paths which are efficient are shown to satisfy a terminal cost minimization condition thereby providing a continuous time counterpart to the discrete time result due to malinvaud using this result competitive paths which are equitable and efficient are shown to satisfy hartwick s investment rule which states that the value of net investment is zero at each date our result indicates that hartwick s rule can help to signal inefficiency of competitive equitable paths journal of economic literature classification numbers c61 d90 o41

environmental issues and economic decisions in developing countries abstract this paper explains the key role of environmental economics in incorporating environmental concerns into decision making and in facilitating the more efficient management of natural resources as a step toward sustainable development it reviews concepts and techniques for valuation of environmental impacts for use in conventional cost benefits analysis as well as key related aspects including environmental impacts of economywide policies multicriteria analysis risk and uncertainty and discount rate issues several developing country case studies are summarized which cover a range of practical valuation methods the evidence presented suggests that the valuation techniques for determining use values may be applied successfully in appropriate cases but examples involving nonuse values are rare the use of multiobjective desicion methods also needs to be explored where economic valuation is not feasible

the quiet revolution that transformed women s employment education and family the modern economic role of women emerged in four phases the first three were evolutionary the last was revolutionary phase i occurred from the late nineteenth century to the 1920s phase ii was from 1930 to 1950 phase iii extended from 1950 to the late 1970s and phase iv the quiet revolution began in the late 1970s and is still ongoing three aspects of women s choices distinguish the evolutionary from the revolutionary phases horizon identity and decision making the evolutionary phases are apparent in time series data on labor force participation the revolutionary phase is discernible using time series evidence on women s more predictable attachment to the workplace greater identity with career and better ability to make joint decisions with their spouses each of these series has a sharp break or inflection point signifying social and economic change these changes moreover coincide by birth cohort or period the relationship between the development of modern labor economics and the reality of women s changing economic role is explored the paper concludes by assessing whether the revolution has stalled or is being reversed women who graduated college in the early 1980s did not opt out but recent cohorts are too young to evaluate this abstract was borrowed from another version of this item

international trade and the sustainability footprint a practical criterion for its assessment a simple and minimal criterion for sustainability is that the value of natural capital plus manufactured capital be not decreasing on the basis of any individual country or region the above simple comparison may be misleading as it does not take account of the production of goods for consumption in other countries regions via international trade in other terms the full environmental footprint of a country may not be properly assessed a method of calculating a weak sustainability criterion has been established for both a closed economy approach and an open economy approach there are significant differences between the open and closed economies measures for several regions particularly the middle east overall global sustainability on this criterion has been positive and increasing using a difference equation approach a further analysis has been made of the average proportional rate of change of global sustainability between 1980 and 1990 and its various regional and structural components have been determined these indicate that most of global sustainability growth can be attributed to western europe other asia and japan particularly through high savings ratios the usa on the other hand has made a very small net contribution to the growth in global sustainability

discounting of long term costs what would future generations prefer us to do decisions with intergenerational consequences may leave future generations worse off i e not be pareto optimal if costs and benefits are not discounted correctly we point out that this happens if the conventional social discount rate is applied to intergenerational costs with that rate the justification of intergenerational costs benefits of a project are invested and the proceeds can cover future costs leads to an inconsistency over the long term eventually the supposed benefits of any project become larger than the entire gnp the conventional approach commits an error by treating the time preference component of the discount rate as if it represented creation of wealth while it really involves only redistribution the time horizon of the redistribution is limited by the duration of market transactions especially loans thus we recommend a two step discounting procedure with the conventional social discount rate for the short term about 30 years and the growth rate of the economy for the long term data for gnp per capita growth in the us the uk france germany japan and the soviet union since the industrial revolution combined with data for net economic welfare per capita suggest an intergenerational discount rate in the range of 1 to 2 for practical application the rate at which costs and benefits will grow over time is just as important as the discount rate only the difference between these two rates matters for many environmental costs these rates may be close to each other during the next few generations this implies that some of the uncertainty in the prediction of rates cancels and one can treat the problem as if the effective rate were close to zero the consequence for costs such as global warming or nuclear power can be very significant the valuation can increase by more than an order of magnitude compared to values based on conventional discounting

measuring the depreciation of australia s non renewable resources a cautionary tale abstract the pursuit of sustainability is widely seen as requiring the calculation and publication of environmentally adjusted measures of national income and or of economic indicators intended to show whether or not economic behaviour is consistent with sustainability requirements in either case a measure of natural resource depreciation is needed the paper restricts its attention to non renewable mineral resources and measures their depreciation in australia according to different methods proposed in the literature using data published by the australian bureau of statistics the different methods are found to yield strikingly different results the conclusion is that robust measurement of natural resource depreciation is unlikely and that results appertaining to such should be treated sceptically

the sustainable residential water use sustainability efficiency and social equity the european experience abstract the present paper traces the operational conditions governing the sustainable use of water in cities towards this objective the paper first proposes a new comprehensive definition for the sustainable use of water next efficiency in use is proposed as a fundamental instrument in achieving sustainability in spite of prevailing opinions maintaining that sustainability and efficiency aim at different and probably conflicting objectives in this light several pricing modes that inhibit efficiency are examined and their effects are defined in this context egalitarian pricing which nevertheless prevents efficiency is also systematically evaluated until it is ascertained that it does not serve social equity in the use of water in the long run all the more the present paper advocates that certain egalitarian pricing systems such as the increasing block rates most prevalent at this time may have the reverse effect than the one intended and hence in the long run impose negative impacts on the welfare of low incomes as a result full cost prices are proposed as a necessary instrument for the sustainable use of water an instrument that promotes social equity in the long run the assumptions of the study are examined in a comparative analysis of representative european pricing systems and urban management modes

seizing community participation in sustainable development pueblos magicos of mexico despite ten years of strategic focus on growth through sustainable tourism few research projects generated understanding of how development policy initiatives contributed to community benefits locally this article addresses this research gap and explores how the aims of local development and cultural sustainability defined in the mexican national tourism program pueblos magicos are put into practice the analysis is focused on how citizenship local participation and democracy are operationalized and what are the local consequences of this governmental program in the community of alamos by following the constitution and decision making processes in the local pueblos magicos committee we demonstrate how different groups bargain on behalf of the community and how they seize the opportunity to promote different development priorities in particular we address the role of a north american migrant community in shaping sustainable tourism development as cultural brokers social entrepreneurs and mediators of market knowledge the paper criticizes the notion of homogenous local communities as an instrumental condition of sustainable and participatory development

genuine savings and sustainability genuine savings gs has emerged as the leading economic indicator of sustainable economic development at the country level it derives from the literatures on weak sustainability wealth accounting and national income accounting we discuss the theoretical underpinnings of gs focusing on the relationship between changes in a nation s extended capital stock and the future path of consumption the indicator has entered widespread use propelled by the world bank s publications despite its varying performance as a predictor for future consumption notwithstanding the extensive body of literature reviewed promising future research avenues are identified

double dividend with involuntary unemployment efficiency and intergenerational equity this paper analyzes the double dividend and distributional issues within an overlapping generations model framework with involuntary unemployment we characterize the necessary conditions needed to obtain a double dividend when the revenue of the environmental tax is recycled by a variation of the labor tax rate we show that an employment dividend may occur without any efficiency dividend and that the young generation is not always harmed by the fiscal reform even without any intergenerational transfers therefore three dividends environmental efficiency and intergenerational equity can occur simultaneously

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

scarcity resource price uncertainty and economic growth over the course of the past decade significant steps have been taken to empirically link indicators of resource scarcity to changes in economic growth this paper extends this previous literature in two ways first rather than concentrating exclusively on energy we focus on the technological change embodied in the prices of an array of complementary natural resource inputs second we investigate using g arch methods the importance of resource price uncertainty as well as resource price levels on aggregate economic growth we find that output growth is significantly influenced by both resource price levels and resource price uncertainty

national accounts and environmental resources in the paper optimal growth theory is used to derive the appropriate definition of the net national product concept when there are environmental resources and environmental damage to take into account the basic conclusions are that conventional defined np should be corrected by deducting environmental damage and adding the value of the net change of all resources

sustainable farm income in the presence of soil erosion an agricultural hartwick rule soil erosion is a physical and economic problem of natural capital degradation even along an intertemporally efficient trajectory one can have in a loss of soil fertility and a continuous decline of agricultural net revenue moreover soil erosion is a major source of surface water pollution in rural areas erosion control is thus a challenge for sustainable resource management and internalizing external effects to sustain the level of farm income an agricultural hartwick rule is proposed which addresses both on farm and off farm effects of soil erosion first it requires the investment of the soil rents into alternative capital second additional measures are required to comply with an ambient quality target a charge subsidy scheme proves the most adequate from a perspective of cost effectiveness and sustainability if effluent charge revenues are earmarked to subsidize cropland retirement at the watershed scale in combination with the investment of soil rents this enables to maintain the level of farm income constant over time while respecting the ambient quality target altogether this fulfills the requirements of efficiency and sustainability 2003 elsevier science b v all rights reserved

the greenhouse effect and intergenerational transfer abstract the scientific basis for understanding the economic issues involved in the greenhouse effect is outlined four important aspects of the problem are identified and discussed irreversibility international and institutional constraints uncertainty and intergenerational equity attention is focused upon the intertemporal choice problem a model describing the potential for intergenerational transfers under the uncertainty of climatic change due to fossil fuel combustion is presented we conclude intergenerational compensation can be achieved by investment in capital or technology or by bequest and is ethically required regardless of any other action

economic analysis of the climate pledges of the copenhagen accord for the eu and other major countries abstract this article uses the world gem e3 computable general equilibrium model to assess the economic consequences of the climate copenhagen accord the model allows analyzing the macroeconomic costs in terms of gdp the change in employment as well as the impacts on production of specific energy intensive sectors various 2020 climate scenarios are evaluated depending on the ghg mitigation pledges we find that the cost for the developed countries is around 0 5 of gdp in 2020 for the more ambitious pledges whereas the gdp effects are more heterogeneous across developing countries and russia reflecting the different pledges and the assumptions in the reference scenario across these countries further the article explores whether there is a form of double dividend in the eu when the revenues from auctioning or taxation of ghg emissions are used to reduce the social security contributions of employees we conclude that gdp and employment perform better compared to the free allocation of permits when more sectors are subject to auctioning or ghg taxes and the additional government revenues are used to reduce the cost of labour

savings growth and the resource curse hypothesis an important connection between recent attempts to understand the determinants of economic growth and the measurement of sustainability is the finding of a negative and significant relationship between natural resource abundance and economic growth this is the so called resource curse hypothesis using cross country regressions we offer evidence that the curse may itself be a manifestation of the inability of governments to manage large resource revenues sustainably in particular these results offer another perspective on the resource curse hypothesis the countries where growth has lagged are those where the combination of natural resource macroeconomic and public expenditure policies have led to a low rate of genuine saving net saving adjusted for resource depletion

investment in schooling and the marriage market we present a model in which investment in schooling generates two kinds of returns the labor market return resulting from higher wages and a marriagemarket return defined as the impact of schooling on the marital surplus share one can extract men and women may have different incentives to invest in schooling because of different market wages or household roles this asymmetry can yield a mixed equilibrium with some educated individuals marrying uneducated spouses when the labor market returns to schooling rises home production demands less time and the traditional spousal labor division norms weaken more women may invest in schooling than men

tourism development in ldcs hotel capacity expansion with reference to barbados abstract the rate of expansion in the hotel sector is critical in a tourist oriented developing country yet difficult to plan in the face of rising and uncertain demand this paper proposes a methodology for determining optimal hotel capacity which is applied to the case of barbados for the period 1979 1984 it is concluded that overbuilding did occur among luxury hotels over the period gains to other tourism sectors very likely compensated for losses but the offsetting is not expected to continue in the future due to rising construction costs

modelling international tourism and country risk spillovers for cyprus and malta abstract small island tourism economies sites are developing sovereign countries that rely on tourism as a source of exports and need a consistent inflow of foreign investment in order to facilitate economic growth access to international capital markets helps sites smooth out their consumption over time while absorbing adverse domestic production shocks this paper provides a comparison of tourism growth country risk returns and their associated volatilities or uncertainty for 2 sites namely cyprus and malta monthly data are available for both international tourist arrivals and composite country risk ratings compiled by the international country risk guide icrg for the period may 1986 to may 2002 the time varying conditional variances of tourism growth and country risk returns for the 2 sites are analysed using multivariate models of conditional volatility empirical results show that cyprus and malta are complementary destinations for international tourists changes to tourism patterns in cyprus lead to changes to tourism patterns in malta hence tour operators and national tourism promotion authorities in cyprus and malta should collaborate closely in marketing and promoting joint tourism products moreover foreign entities interested in investing in the tourism sectors of cyprus and malta should consider investment projects that span a long period of time the performance of the tourism sector and the associated composite risk are independent of each other for the two countries however there is a direct relationship between the tourism sectors of cyprus and malta and their respective country risk settings

intertemporal equity and hartwick s rule in an exhaustible resource model in a standard exhaustible resource model it is known that if along a competitive path investment in the augmentable capital good equals the rents on the exhaustible resource known as hartwick s rule then the path is equitable in the sense that the consumption level is constant over time in this paper we show the converse of this result if a competitive path is equitable then it must satisfy hartwick s rule

environmental equity and sustainability rejecting the kaldor hicks criteria abstract an implementable translation of environmental equity and sustainability is provided for use in benefit cost analysis as such the approach builds on the underlying economic structure of benefit cost analysis while trying to cause it to evolve in ways that take into account issues of greater concern to ecological economists environmental equity and sustainability are interpreted as imposing new decision criteria that require additional benefit cost tests based on actual compensation to identified sub groups of the population this rejects the pre world war ii compromise of economists regarding potential compensation embodied in the kaldor hicks criteria for environmental equity a project is proposed to pass a benefit cost test if the identified group either receives net benefits or is more than compensated for its losses for sustainability a project is proposed to pass a benefit cost test if the compensation is larger than the net value of the resource and the net value of the resource is reinvested

international and intergenerational environmental externalities we examine a world in which policymakers actions in a given country at a given time have long lived effects on a common resource the global environment we consider the first best in which long lived planners behave cooperatively then examine the allocation of resources when there is non cooperation across countries across time or both finally we analyze the dynamic behavior of the economy along balanced growth paths it is found that while long lived international institutions are necessary to internalize all externalities cooperation at a point in time may be harmful to future generations

in search of an appropriate form of tourism for africa lessons from the past and suggestions for the future abstract this paper examines the concepts of leakage tourist dollar flows and social exchange by analyzing historical accounts of conventional processes of tourism development in africa found in the tourism literature it argues that within the context of many sub saharan african economies conventional tourism may actually be more suitable for the developed world than african countries suitable alternative perspectives of development in are suggested

dutch disease and the mitigation effect of migration evidence from canadian provinces this article evaluates whether immigration can mitigate the dutch disease effects associated with booms in natural resource sectors we derive predicted changes in the size of the non tradable sector from a small general equilibrium model a la obstfeld rogoff using data for canadian provinces we find evidence that aggregate immigration mitigates the increase in the size of the non tradable sector in booming regions the mitigation effect is due mostly to interprovincial migration and temporary foreign workers there is no evidence of such an effect for permanent international immigration interprovincial migration also results in a spreading effect of dutch disease from booming to non booming provinces

national account of timber and forest environmental resources in sweden this paper outlines an extension of the national account of income from forest resources in sweden 1987 incorporating changes in timber inventories production of nonmarketed timber and nontimber goods and depletion or improvement in vital environmental stocks such as soil nutrients biodiversity and carbon sinks the total net value added provided by forest resources and forestry labour 1987 is estimated to 22 billions sek this is one third more than the contribution of forestry to ordinary gnp

deforestation and national accounting we construct a first best growing economy in which land is being switched continuously from use in forestry to an alternative use we find that implicitly for such activity to take place there must be no net loss to land owners this implies no deduction in the national accounts for deforestation with soil erosion on deforested land pigovian taxes must be levied to sustain a first best we also observe an optimal tax on households for their implicit use of forests as oxygenation sinks

limits to community participation in the tourism development process in developing countries abstract this study deals with a normative concept of participatory development approach which originates in the developed world in particular it analyses and explains the limitations to the participatory tourism development approach in the context of developing countries it was found that there are operational structural and cultural limits to community participation in the tdp in many developing countries although they do not equally exist in every tourist destination moreover while these limits tend to exhibit higher intensity and greater persistence in the developing world than in the developed world they appear to be a reflection of prevailing socio political economic and cultural structure in many developing countries on the other hand it was also found that although these limitations may vary over time according to types scale and levels of tourism development the market served and cultural attributes of local communities forms and scale of tourism developed are beyond the control of local communities it concludes that formulating and implementing the participatory tourism development approach requires a total change in socio political legal administrative and economic structure of many developing countries for which hard political choices and logical decisions based on cumbersome social economic and environmental trade offs are sine qua non alongside deliberate help collaboration and co operation of major international donor agencies ngos international tour operators and multinational companies

nature or nurture learning and the geography of female labor force participation one of the most dramatic economic transformations of the past century has been the entry of women into the labor force while many theories explain why this change took place we investigate the process of transition itself we argue that local information transmission generates changes in participation that are geographically heterogeneous locally correlated and smooth in the aggregate just like those observed in our data in our model women learn about the efiects of maternal employment on children by observing nearby employed women when few women participate in the labor force data is scarce and participation rises slowly as information accumulates in some regions the efiects of maternal employment become less uncertain and more women in that region participate learning accelerates labor force participation rises faster and regional participation rates diverge eventually information difiuses throughout the economy beliefs converge to the truth participation attens out and regions become more similar again to investigate the empirical relevance of our theory we use a new county level data set to compare our calibrated model to the time series and geographic patterns of participation

education and fertility evidence from a natural experiment declining fertility is often attributed to the increased education of women it is difficult to establish a causal link because both fertility and education have changed secularly in this paper we study the connection between fertility and education using educational reform as an instrument to control for selection our results indicate that increasing education leads to postponement of first births away from teenage motherhood and towards women having their first birth in their 20s as well as for a smaller group up to the age of 35 40 we find no evidence however that more education results in more women remaining childless or having fewer children

the capital gains from trade are not enough evidence from the environmental accounts of venezuela and mexico abstract in principle a country cannot endure negative genuine savings for long periods of time without experiencing declining consumption nevertheless theoreticians envisage two alternatives to explain how an exporter of non renewable natural resources could experience permanent negative genuine savings and still ensure sustainability the first one alleges that the capital gains arising from the expected improvement in the terms of trade would suffice to compensate for the negative savings of the resource exporter the second alternative points at technological change as a way to avoid economic collapse this paper uses the data of venezuela and mexico to empirically test the first of these two hypotheses the results presented here prove that the terms of trade do not suffice to compensate the depletion of oil reserves in these two open economies

capital gains and net national product in open economies it is shown within a given framework that with the world economy following an egalitarian path the aggregate capital gains being positive is equivalent to the interest rate tending to decrease this result is of importance for the concept of net national product in open economies in particular with positive aggregate capital gains an open economy cannot sustain consuming the return on its capital stocks since some part of the return must be used to augment the country s national wealth it is established that a country s share of world wide sustainable consumption equals its share of worldwide wealth

on the regional labour market determinants of female university enrolment in europe casarico a profeta p and pronzato c d on the regional labour market determinants of female university enrolment in europe regional studies this paper empirically investigates how young women s decisions of investing in post secondary education are affected by labour market outcomes of older women living in the same region eu silc data on educational decisions of women who completed secondary schooling are used and indicators of the regional labour market are constructed exploiting regional and time variability it is found that the share of working women with young children of women with managerial positions and the self employed positively affect the probability to enrol significant effects of these variables for men are not found

intergenerational altruism and the environment we construct an overlapping generations model of pollution externality in which individuals are altruistically linked to their offspring as in barro 1974 it is shown that steady state consumption may be a decreasing function of the intergenerational degree of altruism despite individuals altruism the competitive equilibrium is not optimal we thus study the social optimum and show that it can be decentralized

safe port in a storm the impact of labor market conditions on community college enrollments the paper examines the impact of the business cycle on enrollments and finances at individual community colleges between the late 1960s and the mid 1980s we find that 1 percent increases in the unemployment rates of recent high school graduates and of all adults are associated with rises in full time attendance of about 0 5 percent and 4 percent respectively part time enrollment exhibits similar anticyclical patterns this link carries over in large part to degrees obtained in contrast state and local appropriations per student are procyclical we interpret this funding pattern as a failure to integrate education policy sufficiently closely with labor market policy

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

the more the merrier the effect of family size and birth order on children s education there is an extensive theoretical literature that postulates a tradeoff between child quantity and quality within a family however there is little causal evidence that speaks to this theory using a rich dataset on the entire population of norway over an extended period of time we examine the effects of family size and birth order on the educational attainment of children while we find a negative correlation between family size and children s education when we include indicators for birth order and or use twin births as an instrument family size effects become negligible in addition birth order has a significant and large negative effect on children s education we also study adult earnings employment and teenage childbearing and find strong evidence for birth order effects with these outcomes particularly among women these findings suggest the need to revisit economic models of fertility and child production focusing not only on differences across families but differences within families as well

empirical testing of genuine savings as an indicator of weak sustainability a three country analysis of long run trends genuine savings has emerged as a widely used indicator of sustainable development this approach to conceptualising what sustainability is about has strong links to work published by anil markandya and colleagues over 20 years ago in this paper we use long term data stretching back to 1870 to undertake empirical tests of the relationship between genuine savings gs and future well being for three countries britain the usa and germany our tests are based on an underlying theoretical relationship between gs and changes in the present value of future consumption based on both single country and panel results we find evidence supporting the existence of a cointegrating long run equilibrium relationship between gs and future well being and fail to reject the basic theoretical result on the relationship between these two macroeconomic variables this provides some support for the gs measure of weak sustainability

microlending in emerging economies building a new line of inquiry from the ground up the world s poor may be the last great frontier in international business international microlenders are increasingly tapping into this emerging opportunity by extending small business loans to millions of borrowers however to date there is very limited understanding of this domain from an international business perspective using qualitative case studies developed in guatemala and the dominican republic we probe the causes and consequences of high performance and business failure for microloan recipients the analysis of these cases led to the development of six testable propositions focused on the behavior of borrowers whose loans populate the portfolios of international microlenders our research aims to lay a foundation in international business for future research on microlending

long term substitutability between environmental and man made goods abstract substitutability between environmental and man made goods plays a major role in the sustainability debate the notion of substitutability covers a continuous spectrum with perfect substitutability at one end and poor substitutability at the other in this paper it is shown that if economic growth sustains a sharp distinction emerges between perfect and poor substitutability without any intermediate interpretation of substitutability if poor substitutability prevails environmental resources will eventually constitute the major part of total consumption value we relate our results to baumol s disease and assess the implications of this phenomenon for the compensation of environmental losses

building sustainable hybrid organizations the case of commercial microfinance organizations we explore how new types of hybrid organizations organizations that combine institutional logics in unprecedented ways can develop and maintain their hybrid nature in the absence of a ready to w

an overlapping generations model of growth and the environment this article analyzes the potential conflict between economic growth and the maintenance of environmental quality in an overlapping generations model short lived individuals make decisions which have long lasting effects on both factor productivity and the environment the model provides a theoretical explanation of observed correlations between environmental quality and income whereby economic growth is associated first with declines then improvements in environmental quality it suggests circumstances in which multiple pareto ranked steady state equilibria may arise and in which sustained growth of both capital and environmental quality may occur overmaintenance of the environment analogous to dynamically inefficient overaccumulation of capital may emerge copyright 1994 by royal economic society

the anatomy of an informal financial market rosca participation in taiwan abstract little is known about informal financial markets in developing countries this paper analyzes participation in rotating savings and credit associations using a national household survey from taiwan we find that participation is highest among high income households there is some evidence that income stability may play a role as well life cycle differences suggest a role in funding durables purchases our evidence indicates that roscas may be an alternative savings device to the formal financial sector

microcredit social capital and common pool resources abstract the paper presents a conceptual scheme for understanding the impact of microcredit small loans to poor borrowers on common pool resources impacts on common pool resources are posited to occur through changes in household production and consumption the focus on women and the social capital created from group training decision making and risk bearing with the group lending techniques characteristic of many microcredit programs enhanced human and social capital can improve environmental outcomes a nonrandom survey of microfinance organizations suggests increased environmental awareness and potential cpr stewardship through microcredit but empirical research is needed to demonstrate actual impacts

irreversibility and uncertainty cause an intergenerational equity efficiency trade off abstract two important policy goals in intergenerational problems are pareto efficiency and sustainability i e intergenerational equity we demonstrate that the pursuit of these goals is subject to an intergenerational equity efficiency trade off our analysis highlights two salient characteristics of intergenerational problems and policy i temporal irreversibility i e the inability to revise one s past actions and ii uncertainty of future consequences of present actions in human environment systems we employ a two non overlapping generations model that combines an intragenerational production decision on the use of circulating capital and a non renewable resource with a negative intergenerational externality as an unforeseen contingency if initially unknown problems become apparent and policy is enacted after irreversible actions were taken policy making faces a fundamental trade off between ex post pareto efficiency and sustainability that is one can achieve either one of these two goals but not both

tax reform structural unemployment and the environment the effects of environmental tax reform i e using the proceeds of a higher energy tax rate to lower the labour tax rate on wage formation employment and environmental quality are analysed in the context of a small open economy with structural unemployment caused by hiring costs we find that such a reform may boost employment if it shifts the tax burden away from workers towards those without employment in the formal sector environmental tax reform succeeds in shifting the tax burden away from workers in the formal sector if higher energy taxes reduce earnings in the informal sector by reducing labour productivity

from regressive pollution taxes to progressive environmental tax reforms european countries have increased their use of environmental tax instruments by designing new tax bases but many countries face opposition from public opinion for fear of the distributive consequences of these environmental tax reforms this paper sheds light on the distributive consequences of environmental tax policies when households are heterogeneous the objective is to assess whether an environmental tax reform could be pareto improving when the revenue of the pollution tax is recycled by a change in labor tax properties we show that whatever the degree of regressivity of the environmental tax alone it is possible to design a recycling mechanism that renders the tax reform more pareto efficient by simultaneously decreasing the wage tax and increasing its progressivity

reevaluating the first and the second dividends of environmental tax reforms abstract there is increasing global interest in market based climate change policies following the last elections in the united states in this context an exxon mobil chief executive came out in favour of a carbon tax this paper is concerned with the welfare analysis of environmental tax reforms etr and takes up the claims for the need of an unambiguous and operative definition of the double dividend both for empirical purposes and political advisement in this paper we contest the usual definition of the second dividend and its assimilation to an efficiency dividend we propose alternative definitions by suggesting a different splitting of the total welfare variation between the first and the second dividend in order to isolate the efficiency effects of the etr the new definitions become clearly understandable and easy for economic and policy interpretation concepts like weak and strong double dividend turn out to be unnecessary finally we analyze etr for the us economy to illustrate the advantages of the proposed definitions for policy implementation
