Export Bans, Environmental Protection, and Unemployment 总被引:2,自引:0,他引:2
This study investigates the case for an export ban on intermediate goods which generate environmental damage. Since export restrictions on intermediates have long been advocated as a method of stimulating domestic industries in developing countries, we consider whether the case for an export ban is strengthened or weakened by the presence of unemployment in the industrial sector. We find that, in the short run, an export restriction worsens unemployment, thus weakening the case for a ban. In the long run, however, the results are reversed. If the environmental problem is severe, unemployment has a negligible impact on the case for an export ban. 相似文献

This paper develops a general equilibrium model to examine the optimal level of environmental preservation in terms of its costs and benefits for a closed as well as an open economy. The optimal preservation policy for a closed economy is to tax the general population and use the tax revenue to compensate affected workers. Furthermore, for a small open economy, free trade in resources can meet whatever shortage of domestic productive resources that may occur, thereby leading to a higher optimal level of environmental preservation. 相似文献

Environmental Protection and Urban Unemployment: Environmental Policy Reform in a Polluted Dualistic Economy 总被引:1,自引:0,他引:1
Ichiroh Daitoh 《Review of Development Economics》2003,7(3):496-509
This paper explores sufficient conditions for the welfare‐improving environmental policy reform in the Harris–Todaro economy. A rise in the pollution tax rate in the urban manufacturing has spillover effects on the two labor market distortions: the less‐than‐optimal manufacturing employment and the urban unemployment. If both are weakened the welfare improves. Otherwise, we need to develop an alternative sufficient condition. It is shown that there exists a range of welfare‐improving pollution tax rates, and that it corresponds to the lower values of tax rate. This range may shrink by the wage subsidy policy and the technological change toward less pollution‐intensive techniques. 相似文献

Cooperative Management of Groundwater Resources in the Presence of Environmental Externalities 总被引:1,自引:0,他引:1
This paper investigates how cooperation among users can achieve a better management of groundwater in the presence of environmental externalities. Cooperation allows users to internalize the damages caused by their activities and reduce extractions. The paper develops a game theoretical framework to assess the value of cooperation in an aquifer that is divided into three sub-aquifers that are being overly exploited. Two types of externalities are modeled: first, water extractions in each sub-aquifer impact water levels in neighboring sub-aquifers (extraction externality). Second, the three sub-aquifers are also connected to an ecosystem and thus decisions in each sub-aquifer affect the health of the ecosystem (environmental externality). A cooperative game theory model is applied. The model empirically shows how the uncontrolled extractions in each sub-aquifer affects neighboring groundwater users but also cause severe impacts to the linked ecosystem. The model is tested empirically in one of the most important aquifers in Spain, the Eastern la Mancha aquifer. The results illustrate how both extraction and environmental externalities interact in affecting the likelihood of cooperation among the users. The paper estimates the value of cooperation and its stability with and without the environmental externality. 相似文献

The paper develops a general–equilibrium model with layoff unemployment to examine the effect of different unemployment insurance policies on international capital mobility. Conditions are derived under which capital will flow to the high–benefit country. Incentives for international capital movements are unaffected by how the burden of financing unemployment benefits is distributed between workers and firms. It is shown that capital outflows might have positive welfare effects for workers. This contrasts with results from standard models of international factor movements. 相似文献

Optimal Factor Income Taxation in the Presence of Unemployment 总被引:2,自引:0,他引:2
According to conventional wisdom internationally mobile capital should not be taxed or should be taxed at a lower rate than labour. An important underlying assumption behind this view is that there are no market imperfections, in particular that labour markets clear competitively. At least for Europe, which has been suffering from high unemployment for a long time, this assumption does not seem appropriate. This paper studies the optimal factor taxation in the presence of unemployment which results from the union-firm wage bargaining both with optimal and restricted profit taxation when capital is internationally mobile and labour immobile. In setting tax rates the government is assumed to behave as a Stackelberg leader towards the private sector playing a Nash game. The main conclusion is that in the presence of unemployment, the conventional wisdom turns on its head; capital should generally be taxed at a higher rate than labour. 相似文献

This paper offers a new explanation of the recent Australian wage inequality and unemployment experience. Building on a standard international trade model, it is argued that trade affects wage inequality and unemployment through changes in the bargaining power of different groups of workers in the presence of hiring and firing costs. This allows previously puzzling aspects of the trends to be explained, including the inconsistency of the existing Stolper-Samuelson trade explanation with rising relative skilled wages at the same time as rising skilled labour intensity of production. Considering differences in labour market institutions, in particular hiring and firing costs and minimum wages, allows differences between the experiences of Australia, the USA and Europe to be explained. 相似文献

Widespread unemployment has been observed in some developing countries. On the other hand, extensive movement of labor across countries has also been observed. Therefore, in order to examine the interaction between the domestic and international labor markets, this paper develops a model that includes unemployment, international factor movement, and the difference between skilled and unskilled labor. The model examines the effect of production subsidies on unemployment and evaluates their effectiveness as a possible policy in order to alleviate the problem of unemployment. Further, this paper investigates the effects of international factor movement on unemployment and welfare. 相似文献

This paper investigates how the international factor movements affect the unemployment and skilled–unskilled wage inequality with the existence of a modern agricultural sector. Our research has the new feature that we not only consider that the rural labor migrates to the urban sector but also to the modern agricultural sector. The main conclusions are that the unskilled labor outflow certainly decreases the wage inequality and unemployment rate and the influences that skilled labor movement and capital inflow have on wage inequality and unemployment rate are dependent on the factor intensity between the urban and modern agricultural sectors. 相似文献

We consider an environment of a fixed size that can be converted to another use. This conversion can be made in steps, but it is irreversible. The future benefits (per unit) from the original use, and from the alternative use, follow a diffusion process. For a fairly general case, we show that the value function must be the unique (viscosity) solution to the associated Hamilton-Jacobi-Bellman equation. We also exhibit several properties of the solution for the case of constant relative risk aversion between 0 and 1, and a log-linear diffusion for the benefits.

We investigate the welfare effects of environmental tax reform, i.e. raising environmental taxes and using the proceeds to reduce distortionary taxes on labour. The framework of analysis is a small open economy with involuntary unemployment due to a rigid consumer wage. Environmental tax reform boosts not only environmental quality but also employment if substitution between labour and resources is easy, the production share of the fixed factor is large, and the initial tax rates on resources and profits are small. If the initial tax system is sub-optimal with a negligible tax on resources, profits rise as well. 相似文献

We study the environmental and economic effects of public abatement in the presence of multiple stable steady-state ecological equilibria featuring reversible hysteresis. The isocline for the stock of pollution possesses two stable branches. Assuming that the ecology is initially located on the upper (high pollution) branch of the isocline, a simple time-invariant temporary abatement policy can be used to steer the environment from the high- to the low-pollution equilibrium. In all models considered in this paper, a “cold turkey” abatement policy is optimal within the class of stepwise policies, i.e. the largest feasible shock should be administered for the shortest possible amount of time. The cold-turkey result is robust to alternative models for the economic system, although there is a capital feedback effect that either helps or hinders the speed of transition to the low-pollution equilibrium. 相似文献

We examine the hypothesis that induced technological change (ITC) can dramatically lower the cost of a carbon tax in a static optimal tax model. The research and development sector is represented by an aggregate stock of energy-saving technology, which acts as a weak substitute with a polluting resource in the energy generation sector. Using this model, we analytically show how ITC occurs and affects the cost of a carbon tax. Applying quantitative estimates of the size of ITC to numerical simulations calibrated to the US economy, we find that existing empirical evidence can reduce the welfare cost of environmental tax reform by 12%. Our tests of alternative parameters show that this result is highly sensitive to the assumptions used, suggesting that ITC could result in much larger reductions in cost. 相似文献

Co-operation and Unilateral Commitment in the Presence of Global Environmental Problems 总被引:1,自引:0,他引:1
This paper focuses on the link between group co-operation and unilateral commitment of some countries in the presence of global environmental problems. We show that in case of a failure of negotiation, some countries can decide to commit unilaterally and reduce their emissions. We call this behaviour precautionary commitment. Absence of international agreement does not mean global defection from the environmental issue.We also show that the emergence of a non-co-ordinatedglobal co-operation can result from a strategic actionfrom the members of the coalition. The insiders of the coalition create an incentive for the non-members to reduce without co-ordinating their emissions. 相似文献

This paper investigates how a rise in the urban pollution tax rate may affect urban unemployment and welfare in a small open Harris–Todaro (HT) model with intersectoral capital mobility. First, by formulating urban pollution as a dirty input in manufacturing, we find that an increase in the urban pollution tax rate can increase the level of urban unemployment even with intersectoral capital mobility. That is, the optimistic finding by Rapanos (2007 ) that environmental protection policy reduces urban unemployment in the long run does not always hold. Second, the (sub)optimal pollution tax rate under urban unemployment is higher than the Pigouvian tax rate (the marginal damage of pollution). This result opposes those of Beladi and Chao (2006 ) for a closed HT economy and that of Tsakiris et al. (2008 ) for an open HT economy with sector‐specific capital. 相似文献
