Comparing Alternative Policies to Reduce Traffic Accidents AgEcon
Parry, Ian W.H..
This paper derives and implements formulas for the welfare effects of differentiated and uniform mileage taxes, gasoline taxes, and per mile insurance premiums, for reducing the external costs of passenger vehicle accidents. The model distinguishes three driver groups and five vehicle groups, and we obtain estimates of external accident costs per mile for each group from crash data. The (average) external accident cost is estimated at 2.2-6.6 cents per mile. Accidents costs differ substantially across drivers of different ages, but only moderately across different vehicles groups. Annual welfare gains from a mileage tax differentiated across drivers and vehicles according to marginal external costs are $9.4 billion in the benchmark case. The uniform...

Why Governments Tax or Subsidize Trade: Evidence from Agriculture AgEcon
Gawande, Kishore; Hoekman, Bernard.
This paper empirically explores the political-economic determinants of why governments choose to tax or subsidize trade in agriculture. We use a new data set on nominal rates of assistance (NRA) across a number of commodities spanning the last five decades for 64 countries. NRAs measure the effect on domestic (relative to world) price of the quantitative and price-based instruments used to regulate agricultural markets. The data set admits consideration of both taxes and subsidies on exports and imports. We find that both economic and political variables play important roles in determining the within-variation in the NRA data. Based on our results we offer a number of data-driven exploratory hypotheses that can inform future theoretical and empirical...

The Long-Run Effects of Environmental Reform in Open Economies AgEcon
Karp, Larry S.; Zhao, Jinhua; Sacheti, Sandeep.
We compare the short-run and long-run effects of environmental reform and harmonization under autarky and free trade. When trade is driven by environmental distortions rather than real relative advantages, harmonization of environmental policies, even if achieved by lowering standards in one country, can improve short-run aggregate welfare. With the possibility of multiple steady states, long-run considerations favor a "race to the top" rather than a "race to the bottom" even when upward and downward harmonizations are equivalent in the short run. For a country trapped in a low (or bad) steady state, environmental reform may not move it to a high (or good) steady state under autarky. However, under trade, harmonization of policies may enable this country...

Existe un conflicto entre la globalizacion del turismo y los recursos naturales? AgEcon
Font, Antoni Riers; Parrilla, Javier Capo; Tous, Teresa Palmer.
La globalización, así como el turismo internacional, son dos de los fenómenos económicos más analizados en los últimos años, tanto por su creciente importancia como por sus visibles efectos sobre la economía. La notable expansión del turismo tiene como origen, en gran parte, las mismas causas que explican la globalización económica, de ahí que, a menudo, se hable de‘globalización turística’. Uno de los argumentos más utilizados por los detractores de la globalización es su elevado impacto en términos ambientales. En este sentido, resulta obligado reflexionar sobre la existencia de un potencial conflicto entre el, cada vez mayor, desarrollo turístico y la conservación de los recursos naturales. Una cuestión ésta que adquiere especial importancia en el caso...

Estimating the Welfare Effect of Congestion Taxes: The Critical Importance of Other Distortions Within the Transport System AgEcon
Parry, Ian W.H.; Bento, Antonio M..
This paper uses analytical and numerical models to illustrate how the presence of other distortions within the transport system changes the overall welfare effect of a congestion tax. These other distortions include a transit fare subsidy, congestion on competing (unpriced) routes, accident externalities, gasoline taxes, and pollution externalities. Each of these pre-existing distortions can substantially alter the welfare effect of a congestion tax that would be predicted by a first-best analysis. If congestion taxes encourage travel on other congested routes, they can produce sizeable indirect welfare losses. In addition, induced reductions in the demand for gasoline can lead to substantial welfare losses when, as appears to be the case for European...

The Political economy of environmental policy with overlapping generations AgEcon
Karp, Larry S.; Rezai, Amon.
A two-sector OLG model illuminates previously unexamined intergenerational effects of a tax that protects an environmental stock. A traded asset capitalizes the economic returns to future tax-induced environmental improvements, benefiting the current asset owners, the old generation. Absent a transfer, the tax harms the young generation by decreasing their real wage. Future generations benefit from the tax-induced improvement in environmental stock. The principal intergenerational conflict arising from public policy is between generations alive at the time society imposes the policy, not between generations alive at different times. A Pareto-improving policy can be implemented under various political economy settings.

A Tale of Two Market Failures: Technology and Environmental Policy AgEcon
Jaffe, Adam B.; Newell, Richard G.; Stavins, Robert N..
Market failures associated with environmental pollution interact with market failures associated with the innovation and diffusion of new technologies. These combined market failures provide a strong rationale for a portfolio of public policies that foster emissions reduction as well as the development and adoption of environmentally beneficial technology. Both theory and empirical evidence suggest that the rate and direction of technological advance is influenced by market and regulatory incentives, and can be cost-effectively harnessed through the use of economicincentive based policy. In the presence of weak or nonexistent environmental policies, investments in the development and diffusion of new environmentally beneficial technologies are very likely...

The Optimal Climate Policy Portfolio when Knowledge Spills Across Sectors AgEcon
Massetti, Emanuele; Nicita, Lea.
This paper studies the implications for climate policy of the interactions between environmental and knowledge externalities. Using a numerical analysis performed with the hybrid integrated assessment model WITCH, extended to include mutual spillovers between the energy and the non-energy sector, we show that the combination between environmental and knowledge externalities provides a strong rationale for implementing a portfolio of policies for both emissions reduction and the internalisation of knowledge externalities. Moreover, we show that implementing technology policy as a substitute for stabilisation policy is likely to increase global emissions.

Emission Taxes and Tradable Permits: A Comparison of Views on Long Run Efficiency AgEcon
Pezzey, John C.V..
We compare three different views on the long run efficiencies of emission taxes which include thresholds, and of tradable emission permits where some permits are initially free. The differences are caused by different assumptions about whether thresholds and free permits should be subsidies given only to firms that produce, or full property rights. Treating tax thresholds, as well as free permits, as property rights would depart from the conventional view, but would allow greater flexibility in making economic instruments both efficient and acceptable. Such flexibility could be very important in achieving efficent control of greenhouse gas emissions.

Green industrial policy: trade and theory AgEcon
Karp, Larry S.; Stevenson, Megan.
This paper studies the reality and the potential for green industrial policy. We provide a summary of the green industrial policies, broadly understood, for five countries. We then consider the relation between green industrial policies and trade disputes, emphasizing the Brazil-US dispute involving ethanol and the broader US-China dispute. The theory of public policy provides many lessons for green industrial policy. We select four of these lessons, involving the Green Paradox, the choice of quantities versus prices with endogenous investment, the coordination issues arising from emissions control, and the ability of green industrial policies to promote cooperation in reducing a global public bad like carbon emissions.

Using Incentives to Buy Land-Use Change in Agriculture for Environmental Benefits AgEcon
Pannell, David J..
In general, the use of incentive payments to landholders in environmental programs is poorly thought through. This article discusses situations where environmental incentive payments are more likely to be a cost-effective response by environmental funders. It is proposed that incentives can be used in two broad ways: to encourage trialling of new practices by landholders, or to compensate landholders for losses resulting from land-use changes. It appears that environmental funders often do not pay sufficient attention to the differences between these two approaches. The first approach only makes sense if the new practices are 'adoptable', and so are expected to remain attractive to landholders beyond the trialling phase. The importance of adoptability and...

How Large Are the Welfare Costs of Tax Competition? AgEcon
Parry, Ian W.H..
Previous literature has shown that competition among regional governments may lead to inefficiently low levels of capital taxation, because governments do not take account of the external benefits of capital flight to other regions. However, the fiscal distortion is smaller the more elastic the supply of capital (for the region bloc), if governments are not perfectly competitive, or they behave in part as a revenue-maximizing Leviathan. There has been very little empirical work on the magnitude of the welfare effects of fiscal competition. This paper presents extensive calculations of the welfare effects using a model that incorporates the possibility of Leviathan behavior, strategic behavior by governments, monopsony power in factor markets, and a wide...

Invasive Species Management Through Tariffs: Are Prevention and Protection Synonymous? AgEcon
Ranjan, Ram.
This Paper designs a political economy model of invasive species management in order to explore the effectiveness of tariffs in mitigating the risk of invasion. The revenue interests of the government together with the interests of the lobby group competing with the imported agricultural commodity, that is believed to be the vector of invasive species, are incorporated in a Nash Bargaining game. The government, however, also considers the impact of tariffs on long run risks of invasion and decides optimal tariffs based upon its welfare in the pre and post-invasion scenarios. Along with the size of the lobby group, which is a function of the slope of the demand and supply curves, the weights assigned to the various components in the government welfare...

The Impacts of Fees and Taxes on Choices of Development Timing and Capital Intensity AgEcon
Jou, Jyh-Bang; Lee, Tan.
This article compares the effects of various fiscal policies on choices of development timing and capital intensity when rents on housing follow geometric Brownian motion with those when rents follow arithmetic Brownian motion. These policy instruments include fees on capital, housing, and land, and taxes on urban income, and properties both before and after development. Regardless of the motion of rents, when one choice is fixed, the effects of these policy instruments on the other choice are qualitatively the same. When the two choices are determined endogenously, although these policy instruments exhibit the same qualitative effect on the choice of development timing, they may exhibit different effects on the choice of capital intensity if rents on...

Does Britain or the United States Have the Right Gasoline Tax? AgEcon
Parry, Ian W.H.; Small, Kenneth A..
This paper develops an analytical framework for assessing the second-best optimal level of gasoline taxation taking into account unpriced pollution, congestion, and accident externalities, and interactions with the broader fiscal system. We provide calculations of the optimal taxes for the US and the UK under a wide variety of parameter scenarios, with the gasoline tax substituting for a distorting tax on labor income. Under our central parameter values, the second-best optimal gasoline tax is $1.01/gal for the US and $1.34/gal for the UK. These values are moderately sensitive to alternative parameter assumptions. The congestion externality is the largest component in both nations, and the higher optimal tax for the UK is due mainly to a higher assumed...

Distributional Impacts of an Environmental Tax Shift: The Case of Motor Vehicle Emissions Taxes AgEcon
Walls, Margaret; Hanson, Jean.
One of the most common criticisms of pollution taxes is that they are often believed to be inequitable -- i.e., low income households are thought to be disproportionately harmed. In this paper, we assess the distributional impacts of three taxes aimed at reducing emissions from motor vehicles: (i) a tax on total annual emissions, (ii) a tax on emissions rates (in grams per mile), and (iii) a tax on annual miles traveled. We use two alternative measures of economic well-being, annual household income and a constructed measure of lifetime income. We find that all three fees look regressive, both on the basis of annual and lifetime income - though much less so on a lifetime income basis. However, if one of these fees is used to substitute for existing vehicle...

Environmental regulation and horizontal mergers in the eco-industry AgEcon
Canton, Joan; David, Maia; Sinclair-Desgagne, Bernard.
This paper considers the environmental policy and welfare implications of a merger between environment firms (i.e., firms managing environmental resources or supplying pollution abatement goods and services). The traditional analysis of mergers in Cournot oligopolies is extended in two ways. First, we show how environmental policy affects the incentives of environment firms to merge. Second, we stress that mergers in the eco-industry impact welfare beyond what is observed in other sectors, due to an extra effect on pollution abatement efforts; this might lead to disagreements between an anti-trust agency seeking to limit market concentration which can be detrimental to consumer surplus and a benevolent regulator who maximizes total welfare.

Biological Carbon Sinks: Transaction Costs and Governance AgEcon
van Kooten, G. Cornelis.
Activities that remove CO2 from the atmosphere and store it in forest and agricultural ecosystems can generate CO2-offset credits that can thus substitute for CO2 emissions reduction. Are biological CO2-uptake activities competitive with CO2 offsets from reduced fossil fuel use? In this paper, it is argued that transaction costs impose a formidable obstacle to direct substitution of carbon uptake offsets for emissions reduction in trading schemes, and that separate caps should be set for emissions reduction and sink-related activities. While a tax/subsidy scheme is preferred to emissions trading for incorporating biologically-generated CO2 offsets, contracts that focus on the activity and not the amount of carbon sequestered are most likely to lead to the...

Market-Based Instruments for the Optimal Control of Invasive Insect Species: B. Tabaci in Arizona AgEcon
Richards, Timothy J.; Ellsworth, Peter; Tronstad, Russell; Naranjo, Steve.
Invasive insect species represent perhaps one of the most significant potential sources of economic risk to U.S. agricultural production. Private control of invasive insect species is likely to be insufficient due to negative externality and weaker-link public good problems. In this study, we compare a system of Pigouvian taxes with tradable permits for invasive species control. While the emissions control literature shows that taxes are preferred to permits under cost uncertainty, invasive species control involves correlated cost and benefit uncertainty, so we expect a quantity-based system to be preferred. Monte Carlo simulations of optimal steady-state outcomes confirm our expectations.
