an experimental examination of labor supply and work intensities estimated negative substitution effects on work hours question the empirical validity of the classical labor supply model estimates are reconciled by allowing a dual choice of hours and effort for piecerate workers in such a model these negative substitution effects result from substituting on and off the job leisure we test our model using controlled experimentation on human subjects these experiments while not naturally occurring environments represent real economic choices and can generate data unavailable elsewhere e g effort data the results support our model and they have implications both for labor management and for empirical research focusing only on the hours choice the classical static model of the labor leisure choice offers positive compensated wage effects on hours of work as its main testable implication previous attempts to test this hypothesis with field data have cast doubt on the empirical validity of the static labor supply model due to the frequency of negative estimated compensated wage elasticities a limitation of the model is that it views the choice of hours of work as the only

the basic macro economics of oil economies focussing on the rentier aspects of an oil economy where the rent accrues in foreign exchange this paper constructs a simple keynesian model of a typical oil economy increases in oil financed government expenditures in the short run are shown to raise the general price level and the relative price of non tradables sustained increases in oil financed government expenditures are shown to result in an economy whose structure resembles that of the present day oil economies

spatial sustainability trade and indicators an evaluation of the ecological footprint the search for frameworks and indicators of sustainable development has taken a prominent place in this journal however some specific aspects have received little or no attention notably the spatial dimension and the role of international trade in indicator development moreover many sustainable development indicators comprise implicit valuations weighting schemes and policy objectives which are insufficiently recognised as such this contribution tries to highlight these issues by means of a review of a recently proposed indicator for ecological economic analysis namely the ecological footprint that has been developed by wackernagel and rees its concept and calculation procedure are criticised on a number of points and it is concluded that the ecological footprint is not the comprehensive and transparent planning tool as is often assumed in explaining our position we will argue that spatial sustainability and regional sustainable development have not been precisely discussed so far neither in the literature on trade and environment nor in that on sustainable development we will defend the view that trade can contribute positively and negatively to environmental unsustainability consequently indicators and models are needed that allow for analysing interactions and trade offs between such opposite effects 1999 elsevier science b v all rights reserved

in search of a natural systems sustainability index abstract this research note proposes an index of sustainability to be attached to any natural system evaluated according to several indicators of sustainability the proposed index is is very operational and most of the indices proposed in the literature can be considered to be particular cases of is moreover the is propounded can be used to reach balances or compromises between an engineering solution of maximum aggregate sustainability and an ecological solution of most balanced sustainability of the system

from groundless universalism to grounded generalism improving ecological economic indicators of human environmental interaction abstract ecological economics occasionally makes universal claims about how to understand and measure change in systems of human environmental interaction in terms of environmental policy one of the most influential universal concepts that has come out of the ecological economics literature recently is ecological efficiency or eco efficiency this article uses eco efficiency as a vehicle to illustrate that universal indicators of human environmental interaction are theoretically unfounded and practically problematic population ecology and neo classical economics are identified as two theoretical approaches that have contributed to the emergence of universal concepts such as eco efficiency the limited applicability of the approaches is highlighted by putting them in comparative context with approaches that make less universal claims namely systems ecology and institutional economics investigating indicators of human environmental interaction from disciplinary perspectives that are rarely found in indicator literature offers novel insights on what indicators are for and how they should be applied the article concludes with a call for scale sensitive generalization in the development of future indicators

well being and or quality of life in eu countries through a multidimensional index of sustainability abstract the aim of my paper is to demonstrate that sen s theory of well being can be applied to make the concept of sustainable human development operational through the building of a multidimensional index of sustainability which takes into account at the same time economic social and environmental variables this index may be considered an alternative to the current measures of welfare sustainability since not only conventional measures such as gdp but also multi attribute indices such as human development index hdi genuine savings index of sustainable economic welfare isew etc are found to be inadequate to make the concept of sustainable development operational therefore the limitations of these measures of welfare sustainability justify the search for a new index of sustainability this index will show at the operational level how sen s theory of well being can be useful to sustainable development it was applied to eu countries using the standardised deviation methodology being the closest and most suitable methodology to be adopted for building multidimensional indices the factor analysis methodology will also be used in my paper lastly the comparison between sen s trend of sustainability and gdp trend index number which are both of them applied to italy will show how much the criticisms and the limitations directed towards the indicator of gdp are founded

the challenge of measuring biofuel sustainability a stakeholder driven approach applied to the french case measuring biofuel sustainability requires dealing with a wide variety of complex and conflicting values at stake consequently the biofuel capacity to contribute to one specific value cannot lead to any absolute conclusion about the overall sustainability of biofuel the scope of the sustainability concept may vary depending on individuals preferences the time scale and the geographical region based on the 5 pillars sustainability concept that includes social economic environmental legal and cultural considerations the present study proposes to assess several biofuel sustainability options for france by 2030 through a stakeholder driven approach rather than seeking to reach a consensus our approach allows us to capture the wide diversity of stakeholders perspectives and preferences french stakeholders perceive 22 different sustainability criteria for biofuels with a very low level of agreement between the different segments of professions feedstock producers biofuel producers refining industry fuel distributors car manufacturers end users government and ngos in order to operationalize the sustainability assessment a set of indicators has been identified with stakeholders that allows us to measure the capacity of biofuels to fulfill each of their criteria seventeen biofuel options were assessed with regards to economic social environmental cultural and legal considerations allowing the identification of the strengths and weaknesses of each biofuel

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

allocation distribution and scale towards an economics that is efficient just and sustainable abstract the practical policy of issuing tradeable permits for depletion and pollution requires for its implementation the clear separation of the three basic economic goals of efficient allocation equitable distribution and sustainable scale economic theory needs to catch up with policy in recognizing that scale issues cannot be reduced to either allocation or distribution

public multi criteria assessment for societal concerns and gradual labelling we present a multicriteria product assessment framework that can be used to rank existing products against hypothetical product scenarios products are ranked for environmental impact healthfulness naturalness and fairness assessment criteria and relative importance weights are sourced from the public the framework has been demonstrated for fresh tomato production scenarios results are valid because they correspond to public concerns gradient to reward small production improvements and relative to available product alternatives their interpretation can be normative with reference to existing production averages without agreement on absolute acceptability thresholds data improvement agrees with rational stakeholder behaviour results identify technological applications of higher and lower public acceptability potential for production and research agenda optimisation other producer uses include labelling and brand name protection civil society uses include the critical assessment of production public uses include labelling in consumer driven markets and smooth production sector re structuring by incentivizing a race to the top for production externalities of public concern like the environmental sustainability or the fairness of production

why is the labour force participation of women declining in india summary this paper explores the recent fall in female labour force participation and its socio economic determinants in india the major contribution of this paper is to explore both micro and macro level factors which determine female labour force participation rate lfpr to examine the u shape female lfpr by examining the likely income and substitution effects of the real wage increase to identify the sub sectors within manufacturing and service sectors that could create jobs for new female job aspirants and those older women displaced from agriculture in recent years and thus to understand the conditions under which female lfpr could be raised using both macro level and household survey nss data we find that the recent fillip in the process of structural transformation has pushed a large number of females out of agriculture the growing mechanization in agriculture and rising capital intensity in manufacturing sectors together have limited the opportunity for females because of their low education and skill and due to other cultural constraints we also found that the rise in real wages in rural areas and the consequent improvement in the standard of living has produced a strong negative income effect which outweighs the positive substitution effect and as a result female lfpr has declined substantially however with the massive increase in female enrollment in secondary and higher levels of education it could be expected that the substitution effect of the increase in real wage would become stronger if appropriate measures are taken by the government which are suggested

does the labour supply of wives respond to husbands wages canadian evidence from micro data and grouped data using micro data and grouped data we assess the extent to which canadian wives adjusted their labour supply in response to changes in husbands wages during the period 1980 2000 grouped data parameters based on weighted least squares and the unbiased error in variables estimator developed by devereux 2004 2007a b yield cross wage elasticities that are substantially higher in absolute value than those derived from ols regressions run on micro data both grouping estimators indicate that the labour supply of canadian wives responded strongly to changes in husbands wages during the 1980s for the 1990s our estimates of wives cross wage elasticity display greater dispersion a l aide de micro donnees et de donnees groupees on etablit jusqu a quel point les epouses canadiennes ont ajuste leur offre de travail en reponse aux changements dans les salaires de leurs epoux au cours de la periode 1980 2000 les parametres pour les donnees groupees derives par la methode des moindres carres ponderes et de l estimateur developpe par devereux 2004 2007a b engendrent des elasticites croisees qui sont substantiellement plus grandes en termes absolus que ceux derives par la methode des moindres carres ordinaires en utilisant des micro donnees les deux estimations montrent que l offre de travail des epouses canadiennes a repondu fortement aux changements dans les salaires des epoux au cours des annees 80 pour les annees 90 les evaluations des elasticites croisees des salaires montrent une plus grande dispersion

steps towards indicators of sustainable development linking economic and ecological concepts abstract conceptions of defining and measuring sustainable development can broadly be placed in two categories weak and strong sustainability the concept of weak sustainability is based on neo classical economic theory and assumes that manufactured and natural capital are close substitutes this means that costs of environmental deterioration e g forest damage can be compensated by benefits from manufactured capital e g income thus environmental damages are valued in monetary units the concept of strong sustainability denies the degree of substitution that weak sustainability assumes at least for some critical elements of natural capital this paper pledges for strong sustainability indicators especially for critical loads and critical levels since the costs and benefits of avoiding critical impacts have to be taken into account a combination of strong and weak sustainability indicators means a linkage of ecological physical and economic monetary approaches should be suggested

a comparison of the labor force behavior of married women in the united states and canada with special attention to the impact of income taxes estimation results are presented for the probability of working the hourly wage rate and the annual hours of work for wives in seven different age groups in both the u s and canada federal and state or provincial taxes are incorporated into the analysis an iterative estimation method is employed to circumvent the statistical problems resulting from the dependence of the hours of work on the tax rate and the dependence of the tax rate on the hours of work authors

redefining innovation eco innovation research and the contribution from ecological economics while innovation processes toward sustainable development eco innovations have received increasing attention during the past years theoretical and methodological approaches to analyze these processes are poorly developed against this background the term eco innovation is introduced in this paper addressing explicitly three kinds of changes towards sustainable development technological social and institutional innovation secondly the potential contribution of neoclassical and co evolutionary approaches from environmental and innovation economics to eco innovation research is discussed three peculiarities of eco innovation are identified the double externality problem the regulatory push pull effect and the increasing importance of social and institutional innovation while the first two are widely ignored in innovation economics the third is at the least not elaborated appropriately the consideration of these peculiarities may help to overcome market failure by establishing a specific eco innovation policy and to avoid a technology bias through a broader understanding of innovation finally perspectives for a specific contribution of ecological economics to eco innovation research are drawn it is argued that methodological pluralism as established in ecological economics would be very beneficial for eco innovation research a theoretical framework integrating elements from both neoclassical and evolutionary approaches should be pursued in order to consider the complexity of factors influencing innovation decisions as well as the specific role of regulatory instruments and the experience gathered in ecological economics integrating ecological social and economic aspects of sustainable development is highly useful for opening up innovation research to social and institutional changes 2000 elsevier science b v all rights reserved

calculating a water poverty index summary this paper provides discussion of ways in which an interdisciplinary approach can be taken to produce an integrated assessment of water stress and scarcity linking physical estimates of water availability with socioeconomic variables that reflect poverty i e a water poverty index it is known that poor households often suffer from poor water provision and this results in a significant loss of time and effort especially for women by linking the physical and social sciences to address this issue a more equitable solution for water allocation may be found for the purpose of initiating discussion a summary of different approaches to establishing a water poverty index is discussed 2002 elsevier science ltd all rights reserved

sustainable development in pacific micro economies abstract this paper argues that the central economic problem for a number of very small pacific island economies is the preservation and enhancement of their status as rentier societies and the relatively high living standards vis a vis other developing countries which go with the status the thrust of most development planning in the region with its focus on sustainable expansion of productive activity is misdirected in these small countries it is not productive activity but rent entitlements which must be sustained and reproduced over time aid philately and migrant remittances are not merely supplements to local incomes they are the foundations of the modern economy insofar as conventional development projects crowd out aid and remittance entitlements their impact is immiserizing criticism is offered of a recent argument for returning to sustainable subsistence economies

canadian contributions to family economics canadian scholars have made substantial contributions to the relatively new field of family economics these include new models of how men and women match in marriage markets and of how decisions are made in multi person households several were early contributors to the literature on married women s labour supply and labour supply in a family context and helped to develop empirical methods in this area a particular focus has been on the impacts of policy relevant parameters such childcare costs on family labour supply and child well being new work on child development the impact of early life conditions and the processes of intergenerational transmission also highlight the importance of family context in determining economic well being

a regulatory framework for a policy of sustainability lessons from the neo liberal school abstract in this paper targets institutions and policy measures for describing and implementing sustainable development are evaluated in terms of their conformity with the economic framework of a market system from the viewpoint of neo liberal economic thinking as conceived by the german freiburg school of economists a general set of criteria is developed it includes issues of operationalization and legitimation of goals as well as institutional and instrumental issues on this basis general rules for designing an ecological framework guaranteeing the greatest possible degree of conformity with a market system are derived the concrete application of these rules leads to recommendations for a policy of sustainability with respect to the setting of goals the establishment of institutions as well as the use of appropriate instruments

female labour supply in australia another example of a backward bending labour supply curve abstract hours worked by employed married females in australia are analysed using techniques to correct for sample selection bias consistent with the conclusions of the study of female labour supply in the u s and canada by nakamura and nakamura 1981 working wives work fewer hours per week when paid higher hourly wage rates

external shocks and adjustment in a mineral dependent economy a short run model for zambia abstract standard dutch disease analyses would suggest that mineral price declines reverse the effects of mineral booms in particular that the real depreciation caused by the fall in export prices helps revive the traded sectors notably manufacturing zambia s experience however shows that the sectoral impacts of external shocks are much more complex to investigate the tradeoffs inherent in economic adjustment policies including those currently advocated by the international monetary fund imf we use a multisector general equilibrium model the study shows that policies even those directed at a specific sector have indirect but not necessarily benign effects on the rest of the country

more on the labour supply of canadian women the traditional consensus on female labour supply is that the wage elasticity is large and positive in contrast to a small and generally negative elasticity for males this consensus has recently been challenged in a series of important papers by alice and masao nakamura who find a backward bending supply curve for females similar to that for males this result has been challenged on a variety of grounds the present paper tests the hypothesis advanced by the nakamuras on data that have several advantages over the census type in their papers the results offer strong support for the nakamuras conclusions

new estimates of labour supply elasticities for married women in canada 1996 2005 in this article we estimate income and substitution labour supply and participation elasticities for canadian married women using data from the survey of labour and income dynamics 1996 2005 we use the canadian tax and credit simulator ctacs and detailed information on the structure of income at the household level to compute the marginal tax rates faced by each individual we then use these marginal tax rates to compute net own wage spouse wage and nonlabour income we show how the magnitude of the estimated elasticities varies depending on whether net or gross wages and income are used in the estimation procedure and quantify biases caused by using average tax rates instead of marginal tax rates finally because marginal tax rates vary significantly over the sample we use quantile regressions to compare elasticities at different points of the hours distribution overall our results show that public policies now have on average less scope for influencing hours of work than 10 years ago howev

is it retirement or unemployment induced retirement and constrained labour supply among older workers this paper uses the 1986 labour market activity survey of statistics canada to examine the importance of labour demand for hours of work and labour force participation among older workers it tests a model of constrained labour supply against a nested unconstrained alternative and concludes that constraints on weeks of work are empirically significant for older workers a significant fraction of retirement decisions are also influenced by the belief that there are no jobs available

planning for sustainability as a learning concept abstract the major theme of the following discussion is the importance of a transdisciplinary approach to guide sustainability related planning and management activities the proposed approach involves much more than the usual interaction between partners from different disciplines a revised process is needed to allow real cooperation in sustainability planning this process will require a more open recognition of the subjective priorities that become the framework of sustainable development issues of various interest groups and disciplines the sustainable development agenda should be more geared towards learning processes than projected future outcomes learning is enhanced through a participatory framework inclusive of stakeholder interests insights from a broad range of disciplinary areas including the science of complexity sociology philosophy law economics and management are presented to support this position the conventional stranglehold of disciplinary thinking in policy circles limits the capacity of our decision makers to unravel the complexity of all real world environmental policy and management problems policy making needs to embody respect for that complexity and allow flexibility to promote perpetually evolving learning as a fundamentally transdisciplinary framework ecological economics has some prospect to represent these interests in a purposeful and necessarily pragmatic way

green economy and related concepts an overview for the last ten years the notion of a green economy has become increasingly attractive to policy makers however green economy covers a lot of diverse concepts and its links with sustainability are not always clear in this article we focus on definitions of green economy and related concepts and an evaluation of these concepts against the criterion of strong and weak sustainability the article serves three purposes firstly we identify and describe diverse theories concepts approaches and tools related to a green economy among these are the theories of environmental economics and ecological economics the concepts and approaches of cleaner production waste hierarchy bio economy industrial ecology circular economy nature based solutions and dematerialization through product servicizing and tools like life cycle assessment and cost benefit analysis secondly we develop a framework that shows the capacity of the green economy concepts approaches and tools to support the transition towards sustainability such a framework can serve as a heuristic to embed diverse concepts and approaches into a green economy framework thirdly we briefly discuss green economy concepts with respect to their impact on strong and weak sustainability depending on the different concepts approaches and tools identified in the green economy framework different degrees of substitutability and trade offs between environmental and economic benefits are allowed and more or less structural changes of our modes of living are required by discussing the notion of green economy and related concepts approaches and tools we seek to make a contribution to their definitions and relationships as a prerequisite for operationalizing green economy
