The contribution of agriculture to the welfare of society is determined by its economic, social and environmental performance. Although theoretical discussions can be found in the literature, few reports exist that integrate the social demand for multifunctional agriculture in the evaluation of the sustainability and the global welfare of society. This paper presents a methodology that combines economic valuation, integrated modelling, stakeholder analysis, and multi-criteria evaluation. It consists of three steps to determine: (1) social demands for multifunctional agriculture; (2) feasible technical alternatives available from the supply part of the market; (3) the net utility of alternatives for society measured as the change in social net benefit, i.e. the sum of changes compared to the current situation expressed in utility of market and non-market net benefits. Market net benefits are represented by their monetary value. Quality Function Deployment combined with Analytic Network Process (QFD/ANP) were used to estimate the non-market net benefits. The methodology is applied to the case study of a dairy-farming based agricultural landscape in the Northern Friesian Woodlands, The Netherlands. Social net benefit depended on land use, i.e. pasture management regimes on each of the agricultural fields and on presence or absence of hedgerows around the fields. Changes in market net utility were expressed in terms of changes for farmers, consumers and government. Changes in non-market net utility were expressed in terms of changes in landscape quality, nature value and environmental health for Dutch society as a whole, as estimated from European public surveys (Eurobarometer). The complete solution space defined by the market and non-market net benefits of landscapes with alternative patterns of land use was estimated to offer insight in the trade-off between market and non-market performance and enable selection of ‘icon’ landscapes to target or avoid. Improvement of the current landscape towards the social optimum would involve changes in pasture management resulting in higher gross margin for farmers, slightly relaxing current environmental restrictions, which could be reached at lower levels of subsidies in agri-environmental programs. In addition to such overall optimum the results demonstrate the trade-off between market and non-market benefits and the characteristics of current, utopian and dystopian landscapes. The approach provides an alternative to current economic valuation methods which focus on assessment of economic value as an input to analysis. Here, economic value emerges as the trade-off between market and non-market functions which is an output of the analysis.  相似文献

All federal programs are accountable for their use of public funds. This paper presents conservative estimates of the net social benefits associated with the Baldrige National Quality Award Program, established within the National Institute of Standards and Technology in 1987. On the basis of survey data from members of the American Society for Quality, we estimate cost savings benefits to members, extrapolate those benefits to the economy as a whole, and compare the benefits to the social costs associated with the Program. Our estimation method implies that the ratio of economy-wide benefits to social costs probably exceeds 207:1, supporting the hypothesis that the public investments in quality-standards infrastructure are worthwhile.  相似文献

Land-use change has a significant impact on the world’s ecosystems. Changes in the extent and composition of forests, grasslands, wetlands and other ecosystems have large impacts on the provision of ecosystem services, biodiversity conservation and returns to landowners. While the change in private returns to landowners due to land-use change can often be measured, changes in the supply and value of ecosystem services and the provision of biodiversity conservation have been harder to quantify. In this paper we use a spatially explicit integrated modeling tool (InVEST) to quantify the changes in ecosystem services, habitat for biodiversity, and returns to landowners from land-use change in Minnesota from 1992 to 2001. We evaluate the impact of actual land-use change and a suite of alternative land-use change scenarios. We find a lack of concordance in the ranking of baseline and alternative land-use scenarios in terms of generation of private returns to landowners and net social benefits (private returns plus ecosystem service value). Returns to landowners are highest in a scenario with large-scale agricultural expansion. This scenario, however, generated the lowest net social benefits across all scenarios considered because of large losses in stored carbon and negative impacts on water quality. Further, this scenario resulted in the largest decline in habitat quality for general terrestrial biodiversity and forest songbirds. Our results illustrate the importance of taking ecosystem services into account in land-use and land-management decision-making and linking such decisions to incentives that accurately reflect social returns.  相似文献

An integrated economic/ecological model is built to address tradeoffs between biodiversity conservation and two marketable rangeland ecosystem services: cattle grazing and elk hunting. The ecology is represented by an eleven species food web in which individual optimizing plants and animals engage in competitive and predator/prey relationships. The ecological model defines a steady-state set of sustainable grazing and hunting options, and for each option, biodiversity is measured using an index defined over the eleven species. In linking the ecology to the economics, social welfare depends on grazing profits and hunter net benefits. The problem can be stated as maximizing economic welfare over two ecosystem services, subject to their sustainable use and subject to a target level of biodiversity. A numerical application with economic and biological data from the Western United States is used to determine sustainable grazing and hunting options for alternative biodiversity levels, and to select the option that maximizes welfare.  相似文献

In many countries, sickness absence financed by generous insurance benefits is an important concern in the policy debate. There are strong variations in absence behavior among local geographical areas. Such variations are difficult to explain in terms of observable socioeconomic factors. In this paper, we investigate whether such variations are related to group effects in the form of social interaction among individuals within neighborhoods. Well‐known methodological problems arise when trying to answer this question. A special feature of our efforts to deal with these problems is that we adopt several alternative approaches to identify group effects. Our study is based on a rich set of Swedish panel data, and we find indications of group effects in each of our approaches.  相似文献

Previous research has shown that afforestation of agricultural land is a relatively low-cost option compared to energy-based approaches for mitigating net carbon dioxide emissions, and that financial incentives affect landowner behavior and can be used to increase carbon sequestration on private land. In this paper we use stated preference data from private landowners in the Pacific Northwest region of the U.S. to examine the key factors affecting participation in an incentive program for carbon sequestration through afforestation. We also estimate the corresponding potential for carbon sequestration and its cost. Our results suggest that incentive payments would significantly and positively affect landowners⿿ level of enrollment in a tree planting program.  相似文献

The object of this paper is to assess the net distributive impact of state expenditures and revenues on labour income in Greece for the 1958-95 period. This effect is measured by the net social wage defined as the difference between the total benefits received by labour from state spending and the labour taxes. We also discuss certain issues related to the empirical methodology employed in the present and similar studies and the way its inconsistent use has affected inter-country comparisons of the net social wage in the literature. Our empirical findings for Greece indicate that for the entire period no redistribution of income in favour of labour has taken place via the actions of the state. The average net social wage is very close to zero even though during the last decade we observe an increasing involvement of the state in the reproduction of labour. The positive net social wage of the few recent years coincided with high public deficits and appears to be a result of slow growth, high unemployment rates and compensation for the adverse developments for labour in the market distribution of income.  相似文献

Natural resources, capital accumulation and the resource curse   总被引:2,自引:0,他引:2  
Early concern by economists for the effect of natural capital on economic growth gave way to complacency and neglect during the nineteenth century. Evidence has emerged, however, that since the 1960s the economic performance of low-income countries has been inversely related to their natural resource wealth. This relationship is not a deterministic one so policy counts. SEEA can help improve the policy and performance of resource-abundant low-income countries by reinforcing the rationale for the sound management of natural resources and also by providing an index of policy sustainability in the form of the net saving rate. This policy index, along with other measures such as a capital fund for sterilizing the rent, initiatives to increase the transparency of rent flows and the rigorous evaluation of alternative uses of additional public sector revenue can improve the efficiency by which natural resource rent is transformed into alternative forms of capital to sustain rising social welfare. Chad and Mauritania provide case studies to illustrate how SEEA and net saving can be used to diagnose policy failure and improve economic performance.  相似文献

Recently issued U.S. Federal Energy Regulatory Commission regulations require comparable treatment of demand reduction and generation in the wholesale electric market so that they are compensated at the same market clearing price. The new regulations measure demand reduction as a reduction from a “customer baseline,” a historically based estimate of the expected consumption. In this paper, we study the incentive effects on the efficiency of the demand response regulation using a static equilibrium model and a dynamic extension of the model. Our analysis provides three main results. Firstly, our analysis shows that the demand reduction payment will induce consumers to (1) inflate the customer baseline by increasing consumption above the already excessive level during normal peak periods and (2) exaggerate demand reduction by decreasing consumption beyond the efficient level during a demand response event. This result persists when applied to alternative baseline designs in a dynamic model. Secondly, we study alternative policy remedies to restore the efficiency of demand response regulation and introduce a new approach to define the customer baseline as a fixed proportion of an aggregate baseline. In particular, the aggregate baseline approach can significantly weaken or eliminate the incentive to inflate the baseline. Finally, we illustrate that if the baseline inflation problem is solved and demand and supply functions are linear, the current policy can produce a net social welfare gain. However, the welfare improvement requires that demand reduction be paid only when the wholesale price is at least twice the fixed retail rate. This argues that the policy should include a sufficiently high threshold price below which demand response is not dispatched.  相似文献

In this paper, we simulate a macroeconometric model of Slovenia over the period 2012–2060, using the projected demographic development as input, and determine time paths for budgetary and macroeconomic variables under alternative assumptions about Slovenian policy instruments so as to limit budgetary pressures stemming from population ageing. The main macroeconomic indicators (growth, employment, price stability, sustainable public finances) are shown to depend on the assumed long-run policy options followed. It is demonstrated that the ageing of the Slovenian population projected in the demographic forecast leads to severe budgetary problems unless increases of the retirement age, rising social security contributions or reductions of state financed pensions are implemented. A reduction of the pension replacement rate turns out to be the most effective measure to cope with the budgetary implications of population ageing. However, none of the analysed policy measures is sufficient to stabilise the debt ratio.  相似文献

Consumer decisions regarding retail payment instruments entail private and social costs. Due to these social costs, policymakers are increasingly trying to understand the determinants of consumer payment choices as documented by the European Central Bank’s regular publications. This article contributes to this understanding by investigating the role of perceived risk. Based on an original survey of French consumers, we measure the effects of perceived risk on the decisions to hold and use the main retail payment instruments: cash, card and cheque. We point to the sequential dependence of the decisions to hold and use a payment instrument, and study jointly both decisions. The bivariate analysis based on risk factors shows that unavailability risk and time risk have the greatest transverse influence on holding and using payment instruments. Our results, robust to controlling for consumer characteristics, confirm their propensity for a quick-to-use and constantly available payment instrument. We discuss the relevance of our results for policy making purposes.  相似文献

When countries need to implement costly economic policy reforms, these often imply uncertainties about their effectiveness for the home country and their spillovers to other countries. We develop a model to show that under these circumstances countries implement too few or too many policy reforms. From a social perspective, too many reforms follow if the spillover effects of reforms become sufficiently uncertain. Since centralization of policies to correct inefficient policies is often not possible, we look for alternative instruments that can restore the efficient level of reforms. We compare subsidizing reform efforts with insuring against bad outcomes, and argue that subsidies are advantageous in terms of requiring less information for implementation.  相似文献

We explore the welfare implications of agricultural expansion in the Brazilian Amazon by comparing spatially explicit estimates of soybean rents and the value of ecosystem services. Although these estimates are generated from different datasets, models, and estimation techniques, the values are comparable, such that the value of ecosystem services is greater than soybean rents for about 61% of the total area and 24% of the area where soybean rents are positive if protected areas are well enforced. Based on the balance between the benefits and costs of conversion, failure to value ecosystem services reduces total social welfare by 7.13 billion dollars annually relative to an optimum. Policy instruments that internalize the value of ecosystem services via protected lands, land conversion taxes, conservation subsidies, or excise taxes can avoid much of this loss. Regardless of intervention regime, policy makers should be cognizant of the diminishing net benefits of converting natural ecosystems to agriculture. Realizing the final 3.8% requires the conversion of an additional 15% natural ecosystems to soybean production.  相似文献

The literature argues that the benefits of an independent central bank accrue at no cost to the real side. In this paper, we argue that the lack of correlation between monetary autonomy and output variability is due to the proactive role of fiscal policy when faced with rigid monetary objectives. Few of the attempts to measure these correlations actually allow for a changing fiscal role. Yet, when an independent authority handles monetary policy, fiscal and wage/social protection policies remain instruments in the hands of elected governments. We find that, so long as the two authorities pursue their goals independently of each other, a conflict arises that becomes stronger as preferences diverge. We also find that the establishment of a conservative central bank encourages more divergent preferences among the public (as reflected in the government that is elected). The election of more interventionist governments then makes it harder for either authority to reach its own preferred objectives, unless cooperation is possible.  相似文献

目前我国尚未形成统一的环境政策评估规范体系,而对具体环境政策进行评估时,可能会因不同领域、不同视角、不同评估方法而带来不同的评估结果。针对现有环境政策评估体系存在的局限性,提出可以客观评估环境政策实施效果的框架:政策脱轨效应。从政策脱轨效应的定义、产生原因、分类及评估思路四个方面构建理论体系,同时根据脱轨效应理论框架分析我国不同时期的环境政策。该框架体系的基本特点是:将不同环境政策的评估统一到同一体系之下,以特定的模型和方法,评估环境政策实施是否存在"脱轨效应"。研究表明,环境政策实施后存在发生政策脱轨效应的可能性;消费品之间的替代(或互补)关系、单位环境效益和单位产量排污因子均会影响政策脱轨效应的产生;从脱轨效应角度分析,环境政策制定时的决策目标会影响政策实施效果,只有当环境政策以社会净福利为决策目标时,政策实施才可能避免出现政策脱轨效应,实现环境保护和经济增长的双重红利。  相似文献

The present paper aims to quantify efficiency properties of flat and earnings-related pay-as-you-go financed social security systems of various institutional designs in order to identify an optimal pension design. Starting from a benchmark economy without social security, we introduce alternative pension systems and compare the costs arising from liquidity constraints as well as distortions of labor supply versus the benefits from insurance provision against income and lifespan uncertainty. Our findings suggest an optimal replacement rate of about 50 % of average earnings. In our model a single-tier earnings-related pension system yields the highest efficiency gains dominating flat benefits as well as two-tier systems of any form. We also show that the negative correlation between pension progressivity and pension generosity of real-world social security systems can be justified on efficiency grounds. Finally, our results indicate a positive impact of means-testing flat benefits against earnings-related benefits within multi-pillar pension systems.  相似文献

It has been known for a long time that many binary voting rules can select a Pareto dominated outcome, that is an outcome such that there exists some other alternative which is preferred by every voter. In this paper, we show that some of these rules can select an outcome Pareto dominated in a much stronger sense. Furthermore, our main results are concerned with the evaluation of the likelihood of Pareto dominated outcomes under four social choice rules commonly used in Parliaments or in committees. Given a set of four alternatives and a set of n individuals, we assume anonymous profiles and using analytical methods we compute the proportion of profiles at which the Pareto criterion is violated. Our results show that one should not be especially worried about the existence of the possibility as such. We are grateful to two anonymous referees for very helpful remarks and suggestions.  相似文献

A quarter of the total increase in emissions is attributable to the growth of emissions per capita, whereas three-quarters are due to population growth. This evidence notwithstanding, demography in climate–economy models typically follows exogenous trends. We develop a climate–economy integrated model with endogenous fertility through a quality–quantity trade-off. The decentralization of the social optimum requires two complementary instruments: a carbon pricing policy and family planning interventions. Global population increases and reaches a peak, depending on the scenario, between 11.6 billion in the social optimum and 14.6 billion if only carbon prices are implemented. Fertility costs (i.e., the net present value of the climate-related costs per child) are in 2020 estimated to be about 22,000 euros in the “social optimum” scenario, and about 88,000 euros in the “second-best with fertility taxes” scenario. Carbon pricing tends to have a rebound effect as it increases population growth leading to higher future emissions. Our results highlight the effects of fertility choices and global population on climate change, quantifying the cost of neglecting the interaction.  相似文献

The Dawkins and Freebairn paper illustrates the importance of the linkages between unemployment and social security policy, but is not entirely convincing in its explanation of unemployment, the wage-employment elasticity, and the net benefits of a negative income tax.  相似文献

This paper addresses the impact of endogenous technology through research and development (R&D) on the timing of climate change policy. We develop a model with a stock pollutant (carbon dioxide) and abatement technological change through R&D, and we use the model to study the interaction between carbon taxes and innovation externalities. Our analysis shows that the timing of optimal emission reduction policy strongly depends on the set of policy instruments available. When climate-specific R&D targeting instruments are available, policy has to use these to step up early innovation. When these instruments are not available, policy has to steer innovation through creating demand for emission saving technologies. That is, carbon taxes should be high compared to the Pigouvian levels when the abatement industry is developing. Finally, we calibrate the model in order to explore the magnitude of the theoretical findings within the context of climate change policy.   相似文献
