power systems expansion planning with time varying co2 tax abstract this article analyzes the effects of implementing a two stage carbon tax on a ten year power expansion planning model the timing effect of the tax is analyzed by studying the costs capacity investments economic dispatch and co 2 emissions in fixed flat and two stage tax schemes results show that under the absence of political economy constraints the most cost effective solution is to have a low co 2 tax in the first stage and an optimal higher tax in the final stage however early actions can be justified depending on how relevant the policy maker considers the beneficial economic and not economic outcomes of a higher first stage tax consequently focusing on a final period goal may not be the best way of facing the global warming problem if emissions saved early have an important value when preventing the consequences of climate change

the design of environmental markets what have we learned from experience with cap and trade this article reviews the design of environmental markets for pollution control over the past 30 years and identifies key market design lessons for future applications the focus is on a subset of the cap and trade systems that have been implemented planned or proposed around the world three criteria led us to the selection of systems for review first among the broader class of tradable permit systems our focus is exclusively on cap and trade mechanisms thereby excluding emission reduction credit or offset programmes second among cap and trade mechanisms we examine only those that target pollution abatement and so we do not include applications to natural resource management such as individual transferable quota systems used to regulate fisheries third we focus on the most prominent applications those that are particularly important environmentally economically or both

financial markets and growth the last five years have witnessed a resurgence of interest in the relationship between financial intermediation and economic growth this issue had been extensively studied nearly two decades earlier by goldsmith 1969 mckinnon 1973 shaw 1973 and others who produced considerable evidence that financial development correlates with growth but their work though insightful lacked analytical foundations in traditional growth theory financial intermediation could be related to the level of the capital stock per worker or to the level of productivity but not to their respective growth rates the latter were ascribed to exogenous technical progress the recent revival of interest in the link between financial development and growth stems mainly from the insights and techniques of endogenous growth models which have shown that there can be self sustaining growth without exogenous technical progress and that the growth rate can be related to preferences technology income distribution and institutional arrangements this provides the theoretical underpinning that early contributors lacked tinancial intermediation can be shown to have not only level effects but also growth effects the resulting models have offered important insights into the effect of financial development on growth and vice versa they have also provided new impetus to empirical research on these issues this paper reviews the ground covered so far on the theoretical and empirical front and points to some still unresolved issues

the weitzman price corner abstract the standard theoretical approach to comparing price and quantity policies is strictly interior we extend the comparison to account for the possibility of corner outcomes where a polluting industry responds to a tax by abating either completely or not at all we show that when the uncertainty in marginal costs is high the inclusion of corner outcomes confers an extra and unnoticed advantage upon an emissions tax in situations where the standard approach would recommend a quantity policy the possibility of corners can reverse that recommendation

evidence on growth increasing returns and the extent of the market if economic growth relies upon the extent of the market then openness will decrease the connection between initial income and later growth alternatively learning by doing models suggest that wealth will be more positively correlated with growth in open economies because trade causes advanced economies to specialize in products with more opportunities for learning we examine twentieth century less developed countries and nineteenth century u s states in both data sets there is a much stronger correlation between growth and initial wealth among closed economies these findings support the importance of the extent of the market and aggregate demand in fostering growth

network models and financial stability abstract systemic risk is a key concern for central banks charged with safeguarding overall financial stability in this paper we investigate how systemic risk is affected by the structure of the financial system we construct banking systems that are composed of a number of banks that are connected by interbank linkages we then vary the key parameters that define the structure of the financial system including its level of capitalisation the degree to which banks are connected the size of interbank exposures and the degree of concentration of the system and analyse the influence of these parameters on the likelihood of knock on defaults first we find that the better capitalised banks are the more resilient is the banking system against contagious defaults and this effect is non linear second the effect of the degree of connectivity is non monotonic i e initially a small increase in connectivity increases the contagion effect but after a certain threshold value connectivity improves the ability of a banking system to absorb shocks third the size of interbank liabilities tends to increase the risk of knock on default even if banks hold capital against such exposures fourth more concentrated banking systems are shown to be prone to larger systemic risk all else equal in an extension to the main analysis we study how liquidity effects interact with banking structure to produce a greater chance of systemic breakdown we finally consider how the risk of contagion might depend on the degree of asymmetry tiering inherent in the structure of the banking system a number of our results have important implications for public policy which this paper also draws out

the socially optimal recycling rate evidence from japan this paper estimates the average social cost of municipal waste management as a function of the recycling rate social costs include all municipal costs and revenues costs to recycling households to prepare materials estimated with an original method external disposal costs and external recycling benefits results suggest average social costs are minimized with recycling rates well below observed and mandated levels in japan cost minimizing municipalities are estimated to recycle less than the optimal rate these results are robust to changes in the components of social costs indicating that japan and perhaps other developed countries may be setting inefficiently high recycling goals

international trade and air pollution damages in the united states abstract this paper investigates the health and economic consequences of trade due to various air pollutants embodied in exports and imports we compare the us emissions generated for us exports and those that were avoided by importing an input output framework of the us economy is employed together with a comprehensive database on damages expressed in monetary terms generated by pollutants as estimated by muller et al 2011 we find that damages associated with international trade in 2002 were considerable the net result is that damages were avoided through trade and that these avoided damages amounted to 2 7 of the us trade deficit and 3 4 of the us value added associated with trade moreover the computed damage to value added ratios differed greatly across industries exports in some industries are so hazardous that more than half of the value added gained from extra exports disappeared due to environmental damages these findings imply that the us might benefit more from trade by increasing its exports more in low damage intensive products than in high damage intensive products

sulfur dioxide control by electric utilities what are the gains from trade title iv of the 1990 clean air act amendments caaa established a market for transferable sulfur dioxide so2 emission allowances among electric utilities this market offers firms facing high marginal abatement costs the opportunity to purchase the right to emit so2 from firms with lower costs and this is expected to yield cost savings compared to a command and control approach to environmental regulation this paper uses econometrically estimated marginal abatement cost functions for power plants affected by title iv of the caaa to evaluate the performance of the so2 allowance market specifically we investigate whether the much heralded fall in the cost of abating so2 compared to original estimates can be attributed to allowance trading we demonstrate that for plants that use low sulfur coal to reduce so2 emissions technical change and the fall in prices of low sulfur coal have lowered marginal abatement cost curves by over 50 percent since 1985 the flexibility to take advantage of these chan

convergence across canadian provinces 1961 to 1991 the purpose of this study is to provide a new look at the evolution of regional disparities in canada in the light of the recent convergence studies produced by european and american economists the degree of convergence of a variety of per capita income and output measures from 1961 to today is analysed the empirical analysis suggests that there is evidence of convergence in canada for different measurements of per capita income and output since the early 1960s during this period convergence has been helped by a favorable change in terms of trade and by government transfers and taxes our estimates of the convergence speed for canadian provinces are of the same magnitude as those found for regions within the same country and across countries in european and american studies

borrowing constraints human capital accumulation and growth abstract borrowing constraints increase aggregate savings and therefore may increase growth this paper argues however that by reducing human capital accumulation borrowing constraints also have negative effects on growth these effects are discussed in an overlapping generations model with endogenous growth empirical evidence for oecd and developing countries lend support to the main predictions of the model

financial intermediation and endogenous growth an endogenous growth model with multiple assets is developed agents who face random future liquidity needs accumulate capital and a liquid but unproductive asset the effects of introducing financial intermediation into this environment are considered conditions are provided under which the introduction of intermediaries shifts the composition of savings toward capital causing intermediation to be growth promoting in addition intermediaries generally reduce socially unnecessary capital liquidation again tending to promote growth

stock markets and development this paper asks if financial development especially stock market development affects the level and or the growth rate of economic activity it finds a substantial effect on both current wisdom suggests that the growth effects of financial intermediation could be either permanent or transitory for instance the greenwood jovanovic 1990 henceforth gj model has an ak stucture with no diminishing returns to the reproducible factor and a permanent exogenous improvement in financial structure would cause a permanent increase in the rate of growth on the other hand if the returns to the reproducible factor did diminish better intermediation could lead only to level effects since one should not a priori exclude either growth effects or level effects we shall look for both our search for growth effects will use the gj model our search for level effects will rely on an amended version of the mankiw romer and weil 1992 henceforth mrw structure

a geographically resolved method to estimate levelized power plant costs with environmental externalities in this analysis we developed and applied a geographically resolved method to calculate the levelized cost of electricity lcoe of new power plants on a county by county basis while including estimates of some environmental externalities we calculated the lcoe for each county of the contiguous united states for 12 power plant technologies the minimum lcoe option for each county varies based on local conditions capital and fuel costs environmental externalities and resource availability we considered ten scenarios that vary input assumptions we present the results in a map format to facilitate comparisons by fuel technology and location for our reference analysis which includes a cost of 62 tco2 for co2 emissions natural gas combined cycle wind and nuclear are most often the lowest lcoe option while the average cost increases when internalizing the environmental externalities carbon and air pollutants is small for some technologies the local cost differences are as high as 0 62 kwh for coal under our reference analysis these results display format and online tools could serve as an educational tool for stakeholders when considering which technologies might or might not be a good fit for a given locality subject to system integration considerations

measuring the damages of air pollution in the united states abstract this paper measures the damages due to emissions of air pollution in the united states an integrated assessment model is used to calculate the marginal damage associated with emitting an additional ton of pollution from nearly 10 000 sources in the u s the total damage produced by a source is the marginal damage of an emission its shadow price times the total tons emitted from a specific source adding total damages across all sources yields gross annual damages gad which is a green accounting parallel to gross domestic product gdp gad in 2002 varies between 71 billion and 277 billion 0 7 2 8 of gdp the range of values depends largely on the value of health and the concentration response function relating exposures to fine particulate matter pm 2 5 to adult mortality rates source location also matters urban emissions constitute 52 of total emissions by weight yet they cause nearly three quarters of the gad

a moral hazard trap to growth this paper studies the consequences of asymmetric information in the investment sector upon economic growth in this paper the information asymmetry generates a moral hazard problem this moral hazard problem restricts financial arrangements it is shown that these restrictions make even the long run competitive equilibrium income dependent upon history this result also holds in case there is perfect capital mobility however when there is capital mobility the government may be able to intervene in a pareto improving way copyright 1992 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

environmental accounting for pollution in the united states economy this study presents a framework to include environmental externali ties into a system of national accounts the paper estimates the air pollution damages for each industry in the united states an inte grated assessment model quantifies the marginal damages of air pol lution emissions for the us which are multiplied times the quantity of emissions by industry to compute gross damages solid waste com bustion sewage treatment stone quarrying marinas and oil and coal fired power plants have air pollution damages larger than their value added the largest industrial contributor to external costs is coal fired electric generation whose damages range from 0 8 to 5 6 times value added jel e01 l94 q53 q56

an economic analysis of scrappage this article examines the impact of policies aimed at encouraging the retirement of older high polluting vehicles such as the cash for clunkers policy endorsed by president george bush in 1992 the analysis assesses the likely benefits and costs of vehicle scrappage programs i also address the interaction of a scrappage program with other ongoing policies such as improved inspection and maintenance finally the simulation for los angeles suggests plausible design values for a scrappage program

endogenous technical change and environmental regulation abstract a model of environmental regulation under uncertainty is developed to compare the effect of price versus quantity rules upon technical change quantity rules tend to encourage more efficient levels of technical change

financial contagion and attention allocation this paper explains financial contagion between two stock markets with uncorrelated fundamentals by fluctuations in international investors attention allocation we model the process of attention allocation that underlies portfolio investment in international markets using investors who face information processing constraints investors optimally allocate more attention to a region hit by a financial crisis to the detriment of other markets the resulting endogenous increase in uncertainty causes a reduction in the capacity to bear risks by international investors that induces them to liquidate their positions in all risky assets hence there is a collapse in stock prices around the world we show that the degree of non anticipation of a crisis is crucial for the existence of contagion using data from the east asian crisis and the number of news stories about thailand in the financial times relative to news stories about argentina brazil and chile as a proxy for the relative attention allocated to the asian stock market we find evidence consistent with two key predictions of our model first the higher the volatility of the originator market the more relative attention allocated to this market and second the more relative attention allocated to the originator market the higher the volatility of the other markets our findings support the attention reallocation channel as a transmission mechanism of financial crises between regions during the period from january 1997 to july 1998

incentive based policy design for pollution control and biodiversity conservation a review this paper provides a succinct review of the main developments in the literature on incentive based policy mechanisms in the contexts of pollution control and biodiversity conservation dating from the early beginnings of the science in the 1960s a focal point in the review is on the design features of these policy mechanisms key developments in policy design were originally established in controlling externalities arising from pollution and have since been extended to policy design tailored towards biodiversity conservation special emphasis is given to the spatial characteristics of the environmental problems underlying both pollution control and biodiversity conservation the paper concludes by drawing some lessons and setting out elements of a future research agenda in both policy domains

an interim evaluation of sulfur dioxide emissions trading ide iv of the 1990 clean air act amendments established the first large scale long term environmental program to rely on tradable emissions permitscalled allowances in this program to control pollution this program was designed to cut acid rain by reducing sulfur dioxide so2 emissions from electric generating plants to about half their 1980 level beginning in 1995 it is of interest both as a response to an important environmental issue and as a landmark experiment in environmental policy this experiment comes at a particularly important time since emission trading is under serious consideration with strong u s backing for use to deal with global climate change by curbing emissions of carbon dioxide co2 the economic stakes in climate change surpass those in acid rain by several orders of magnitude intergovernmental panel on climate change 1996 this article summarizes the results to date of our ongoing empirical analysis of compliance costs and allowance market performance under the u s acid rain program

uniqueness and indeterminacy on the dynamics of endogenous growth abstract in this paper we study the dynamics of endogenous growth both in the model of lucas and in a generalization that incorporates a labor leisure choice we characterize the regions of the parameter space that give rise to unique equilibria as well as the regions that yield a continuum of equilibria with positive growth rates we find that such multiple equilibria exist for empirically very plausible parameters in particular when the lucas model is modified to incorporate endogenous labor journal of economic literature numbers e00 e3 o40

nonconvexity induced by external costs on production theoretical curio or policy dilemma this paper considers with a degree of scepticism the sweeping policy conclusions that can be found in the theoretical literature concerning nonconvexit ies in the social production set induced by external costs on firms this literature has provided proofs of the possibility that such nonconvexit ies exist but these proofs have readily been interpreted as a basis on which to judge the advisability of policies to control external costs 2 indeed a number of authors have felt able to proceed from specific theoretical examples of the existence of nonconvexity to the opinion that nonconvexity represents a general obstacle to policy one of the ma in themes will be to demonstrate that the theoretical possibility of the existence of a nonconvexity at a m icro level does not imply the existence of a m icro or a fortiori macro nonconvexity in the real world nor does it imply that any nonconvexity that does exist in reality is relevant to policy the intention is not to deny that nonconvexit ies may represent an obstacle to the efficient control of external costs in specific contexts but in order to establish the real world policy relevance of a nonconvexity it is necessary to verify its existence emp irically and to establish that it stands in a particular relationship to the no policy starting point

the control of invasive species on private property with neighbor to neighbor spillovers invasive pests cross property boundaries property managers may have private incentives to control invasive species despite not having sufficient incentive to fully internalize the external costs of their role in spreading the invasion each property manager has a right to future use of his own property but his property may abut others properties enabling spread of an invasive species the incentives for a foresighted property manager to control invasive species have received little attention we consider the efforts of a foresighted property manager who has rights to future use of a property and has the ability to engage in repeated discrete control activities we find that higher rates of dispersal associated with proximity to neighboring properties reduce the private incentives for control controlling species at one location provides incentives to control at a neighboring location control at neighboring locations are strategic complements and coupled with spatial heterogeneity lead to a weaker link public good problem in which each property owner is unable to fully appropriate the benefits of his own control activity future use rights and private costs suggest that there is scope for a series of coase like exchanges to internalize much of the costs associated with species invasion pigouvian taxes on invasive species potentially have qualitatively perverse behavioral effects a tax with a strong income effect e g failure of effective revenue recycling can reduce the value of property assets and diminish the incentive to manage insects on one s own property

the welfare consequences of mixed environmental policy instruments with voluntary provision this article evaluates the welfare consequences of a mixed regulatory framework with a voluntary cap and trade program and intensity standards using data from the texas electricity industry i construct and estimate a structural model of the compliance choices of power generating units to recover their abatement costs then i simulate for the counterfactual equilibrium under a mandatory cap and trade regulation results show that the mixed policy framework mainly benefits generating units with small capacity and high abatement costs however a mandatory cap and trade regulation with redistribution policies could bring in substantial pareto improvement

pattern formation spatial externalities and regulation in coupled economic ecological systems abstract we study the management of ecosystems in which interacting state variables that are affected by management decisions diffuse in space we study pattern formation first in a setting where economic agents maximize myopic profits and ignore spillovers onto agents at other sites and second in the context of a social planner who internalizes these spillovers we compare patterns under these two institutions and study how the differences in the patterns generated by these two institutions impact the design of regulatory schemes to internalize the externalities at the same time we introduce new methods based on fourier series type decompositions that enable us to turn an intractable infinite dimensional optimal control problem into a countable number of finite dimensional optimal control problems as far as we know these methods are new to the economics literature our theory is applied to the management and regulation of a semi arid system

fiscal federalism and interjurisdictional externalities new results and an application to us air pollution abstract the economics of fiscal federalism has identified two book end departures from first best provision of a public good local governments may respond to local conditions but ignore inter jurisdictional spillovers alternatively central governments may internalize spillovers but impose uniform incentives ignoring local heterogeneity we provide a simple model that demonstrates that the choice of pricing policy also depends crucially on a third factor the shape of marginal costs of providing the public good if marginal costs are convex then marginal abatement cost elasticities will be higher around the local policies this increases the deadweight loss of those policies relative to the centralized policy ceteris paribus if they are concave then the opposite is true using a detailed simulation model of the us electricity sector we then empirically explore these tradeoffs for us air pollution we find that us states acting in their own interest lose about 31 5 of the potential first best benefits whereas the second best uniform policy loses only 0 2 of benefits the centralized policy outperforms the state policy for two reasons first inter state spillovers are simply more important that inter state heterogeneity in this application second because of the convexity of the marginal cost functions elasticities are much lower over the range relevant to the centralized policy dampening the distortions

multiple pollutants co benefits and suboptimal environmental policies abstract in our analytical general equilibrium model polluting inputs can be substitutes or complements we study a tax increase on one pollutant where the other faces a tax or permit policy our solutions highlight key parameters and welfare effects with gains from abatement plus positive or negative co benefits from other pollutants in the covered and uncovered sectors we demonstrate several ways taxes and permits differ first the change in taxed pollutant depends on whether the other pollutant faces a tax or permit policy also only with a tax on the other pollutant can a co benefit arise the sign of co benefits depends on the sign of cross price elasticities and on whether the other pollutant s price is above or below marginal damages finally the other pollutant s tax or permit policy also affects emissions in the uncovered sector leakage in a numerical illustration of carbon tax in u s electricity we calculate emissions of co2 and so2 in both sectors for plausible parameters co benefits are larger than direct

are there environmental benefits from driving electric vehicles the importance of local factors we combine a theoretical discrete choice model of vehicle purchases an econometric analysis of electricity emissions and the ap2 air pollution model to estimate the geographic variation in the environmental benefits from driving electric vehicles the second best electric vehicle purchase subsidy ranges from 2 785 in california to 4 964 in north dakota with a mean of 1 095 ninety percent of local environmental externalities from driving electric vehicles in one state are exported to others implying they may be subsidized locally even when the environmental benefits are negative overall geographically differentiated subsidies can reduce deadweight loss but only modestly

consequences of the clean water act and the demand for water quality since the 1972 u s clean water act government and industry have invested over 1 trillion to abate water pollution or 100 per person year over half of u s stream and river miles however still violate pollution standards we use the most comprehensive set of files ever compiled on water pollution and its determinants including 50 million pollution readings from 240 000 monitoring sites and a network model of all u s rivers to study water pollution s trends causes and welfare consequences we have three main findings first water pollution concentrations have fallen substantially between 1972 and 2001 for example the share of waters safe for fishing grew by 12 percentage points second the clean water act s grants to municipal wastewater treatment plants which account for 650 billion in expenditure caused some of these declines through these grants it cost around 1 5 million 2014 dollars to make one river mile fishable for a year we find little displacement of municipal expenditure due to a federal grant third the grants estimated effects on housing values are smaller than the grants costs we carefully discuss welfare implications

modeling financial contagion using mutually exciting jump processes we propose a model to capture the dynamics of asset returns with periods of crises that are characterized by contagion in the model a jump in one region of the world increases the intensity of jumps both in the same region self excitation as well as in other regions cross excitation generating episodes of highly clustered jumps across world markets that mimic the observed features of the data we develop and implement moment based estimation and testing procedures for this model the estimates provide evidence of self excitation both in the us and the other world markets and of asymmetric cross excitation with the us market typically having more influence on the jump intensity of other markets than the reverse we propose filtered values of the jump intensities as a measure of market stress and examine their out of sample forecasting abilities

optimal tax policy under heterogeneous environmental preferences abstract we model an economy of k heterogeneous regions where agents value consumption vs nature differently consumption obtained through pollution inducing production also generates a negative externality on neighbors we show that even with a decentralized policy we can obtain first best efficiency by choosing a combination of pollution taxes in both regions and lump sum transfers moreover we show that optimal pollution taxes are determined only by the externality parameters independent of agents preferences for consumption and nature

determinants of participation in accelerated vehicle retirement programs one potential way to reduce hydrocarbon emission is through accelerated vehicle retirement programs however it is difficult to forecast participation rates in these programs because the number and characteristics of participants are likely to vary with the price offered to attract old cars this paper presents a theoretical model of the owner s car tenure and scrappage decision an econometric model of participation is then developed and estimated using data from a recent old vehicle scrap program in delaware participation rates at different possible offer prices are then predicted

information contagion and bank herding we show that the likelihood of information contagion induces profit maximizing bank owners to herd with other banks when bank loan returns have a common systematic factor the cost of borrowing for a bank increases when there is adverse news on other banks since such news conveys adverse information about the common factor the increase in a bank s cost of borrowing relative to the situation of good news about other banks is greater when bank loan returns have less commonality in addition to the systematic risk factor hence banks herd and undertake correlated investments so as to minimize the impact of such information contagion on the expected cost of borrowing competitive effects such as superior margins from lending in different industries mitigate herding incentives

the problem of the commons still unsettled after 100 years the problem of the commons is more important to our lives and thus more central to economics than a century ago when katharine coman led off the first issue of the american economic review as the us and other economies have grown the carrying capacity of the planet in regard to natural resources and environmental quality has become a greater concern particularly for commonproperty and open access resources the focus of this article is on some important unsettled problems of the commons within the realm of natural resources there are special challenges associated with renewable resources which are frequently characterized by open access an important example is the degradation of openaccess fisheries critical commons problems are also associated with environmental quality a key contribution of economics has been the development of market based approaches to environmental protection these instruments are key to addressing the ultimate commons problem of the twenty first century global climate change jel q15 q21 q22 q25 q54

your money or your life green growth policies and welfare in 2050 this paper proposes a simple index of economic progress that weighs in the monetary cost induced by climate change mitigation policies as well as the health benefits arising from the reduction in local air pollution the shadow price of pollution is calculated indirectly through its impact on life expectancy taking into account the health benefits of mitigation policies significantly reduces their monetary cost in china and india as well as in countries with large fossil based energy producing sectors australia canada and the united states

market design in cap and trade programs permit validity and compliance timing abstract cap and trade programs have considerable heterogeneity in permit validity and compliance timing for example permits have different validities across time e g banking borrowing and seasons and space e g zonal restrictions and compliance timing can be annual in overlapping cycles or in multi year periods we discuss nine prominent cap and trade programs along these dimensions and construct a general model of permit validity and compliance timing we derive sufficient conditions under which abatement is invariant to compliance timing i e compliance timing cannot smooth abatement cost shocks under these conditions i expected compliance costs are invariant ii the variance of compliance costs increases with the delayed compliance iii equilibrium prices may not be unique and iv the delayed compliance equilibrium may rely on degenerate prices not determined by marginal abatement costs we demonstrate the model s broad applicability by illustrating different types of temporal permit validity

an assessment of two environmental and economic benefits of cash for clunkers abstract this research aims to provide a more comprehensive life cycle accounting of two categories of environmental and economic benefits associated with the 3 billion us cash for clunkers vehicle scrappage program first using a life cycle emissions methodology developed in lenski et al 2010 we find that about 29 000 metric tons of criteria pollutant emissions were avoided for a benefit of about 23 million avoided carbon dioxide emissions by comparison provided a benefit worth 90 million second we compare the market value of scrapped vehicles to the rebates provided calculating the consumer surplus or gift to participants to be up to 2 billion about 2000 to 3000 per vehicle this is significantly more than offered in previous vehicle scrappage programs and suggests opportunities to get more environmental and economic bang for the buck finally these two categories of benefits are found to be heavily concentrated geographically around urban centers about 2 of us counties 50 counties received 50 and 30 of the aggregate benefits from avoided criteria pollutant emissions and consumer surplus from the rebates respectively

the derivation of discount rates with an augmented measure of income abstract most developed economies invest in public goods such as national defense education infrastructure and the environment discount rates used to evaluate such projects should reflect the rate of return on the current mix of investment opportunities rates derived from the productivity of private capital neglect returns beyond the market boundary the present paper derives discount rates using an augmented measure of national income inclusive of non market goods in an empirical application focusing on air pollution and climate damages in the united states economy the paper reports that the difference between augmented and market discount rates averages 0 3 percentage points from 1999 to 2014

indeterminacy and increasing returns abstract we investigate properties of the one sector growth model with increasing returns under two organizational structures capable of reconciling the existence of aggregate increasing returns with competitive behavior by firms the first involves input externalities the second involves monopolistic competition we show for parameters in close accord with recent literature on real business cycles that the model displays an indeterminate steady state that can be exploited to generate a model of business fluctuations driven by self fulfilling beliefs in our first class of models growth is generated by exogenous increases in factor productivity in the second class the marginal product of capital is large enough for endogenous growth journal of economic literature classification numbers e00 e3 o40

economic spillovers in spatial harvest behavior abstract there has been a strong push within natural resource management to incorporate spatial structure into management regimes however discussions surrounding the appropriate designs of spatial management have largely been conceptual this paper develops a spatial econometric model of fishing location choice using non confidential data from the great barrier reef coral trout commercial fishery harvest location decisions are modeled as a function of spatial patterns of expected economic returns the preferred spatially dependent econometric model is shown to outperform ordinary least squares and fixed effects models in out of sample forecasting estimates from the spatial model reveal spatial spillover effects in fleet harvest location behavior in particular harvest activity at any given site is equally sensitive to same site economic returns and surrounding site economic returns the econometric results are illustrated using a fee based policy simulation results suggest non spatial management is characterized by two inefficiencies first heterogeneity between sites is averaged resulting a fee that is too high or too low across space second fees that are too high or too low affect the fishing effort in nearby locations

the compensation regime in liability law incentives to curb environmental harm ex ante and ex post this paper analyzes private incentives for precautions against environmental harm before accidents occur and for clean up after the fact we consider the compensatory regimes used in various jurisdictions which differ in terms of the basis for compensation the level of harm clean up costs or some combination of the two and the resulting levels of compensation we establish that socially optimal decisions are usually not induced by liability law in any of the compensatory regimes however the different types and levels of compensation have distinct effects allowing the policy maker to identify the most appropriate regime for specific circumstances

human capital urbanization and canadian provincial growth coulombe s 2003 human capital urbanization and canadian provincial growth reg studies 37 239 250 this paper investigates the conditional convergence of both human capital indicators and nominal per capita income across canadian provinces in a panel data empirical framework long run relative provincial steady states are determined by relative rates of urbanization one time shocks to quebec s and alberta s relative steady states and a nova scotia fixed effect indicators of relative human capital ratios appear to have converged following a pattern that is common and similar to per capita income but with two notable exceptions first in alberta the 1973 oil shock contributed to the rise in per capita income but its effect on human capital is significant only for females second human capital appears to remain concentrated in the relatively poor province of nova scotia two notable findings come out of the analysis first nominal income disparities at the provincial level appear to be real no

non market valuation in integrated assessment modeling the benefits of water right retirement abstract the impact of resource management on natural capital value depends on processes that affect resource stocks over space and time we develop an integrated assessment modeling framework that links econometric estimates of non market benefits from a resource stock to a spatially explicit model of resource dynamics results from a dichotomous choice contingent valuation survey are used to estimate a marginal willingness to pay function for groundwater which has no market we use the model to measure the economic benefits to agricultural producers of a program that pays for water right retirement under the baseline scenario without water right retirement the benefits from groundwater stocks in the study region decline in value by 3 6 million over 15 years because of groundwater depletion water right retirement leads to groundwater benefits that are 0 55 million higher than in the baseline after 15 years but benefits vary greatly over space comparing this to an explicit program cost of 45 million suggests that other social benefits from groundwater stocks must exist to justify the program from a benefit cost perspective valuing the economic benefits from increasing natural capital stocks can inform policy and provide insight into the value of management in resource and environmental systems

optimal trading ratios for pollution permit markets abstract we demonstrate a novel method for improving the efficiency of pollution permit markets by optimizing the exchange of emissions through trade under full information it is optimal for emissions to exchange according to the ratio of marginal damages under asymmetric information we derive necessary conditions for the marginal damage trading ratios to be optimal illustrate that the marginal damage trading ratios are generally not optimal and show how to improve efficiency using optimal trading ratios we calculate the optimal trading ratios for a global carbon market the gains from using optimal trading ratios rather than marginal damage trading ratios range from substantial to trivial which suggests the need for careful consideration of asymmetric information when designing permit markets

wind coal and the cost of environmental externalities abstract we compare the cost of generating electricity with coal and wind in chile on average we estimate that the levelized cost of coal including externalities is 84 mwh it is efficient to abate air pollutants so x no x and pm 2 5 but not co 2 with abatement the cost wrought by environmental externalities equals 23 mwh or 27 of total cost depending on the price of coal the levelized cost may vary between 72 and 99 mwh the levelized cost of wind is 144 mwh with capacity factor of 24 this cost includes backup capacity to maintain lolp which equals 13 mwh or 9 of total cost the levelized cost of wind varies between 107 mwh with capacity factors of 35 to 217 mwh with capacity factors of 15 wind is competitive only with capacity factors around 35 and very high coal prices alternatively a carbon price of 73 tco 2 268 tc would make coal and wind equally costly but this value implies a marginal damage at the 98th percentile of the distribution deduced from tol s 2011 estimates rather far from the mean 16 tco 2 59 tc

systemic risk financial contagion and financial fragility abstract although it is hard to arrive at a widely accepted definition for systemic risk it is generally acknowledged that it is the risk of the occurrence of an event that threatens the well functioning of the system of interest financial payments banking etc sometimes to the point of making its operation impossible we model systemic risk with two main components a random shock that weakens one or more financial institutions and a transmission mechanism which transmits and possibly exacerbates such negative effects to the rest of the system our model could be conceptually represented by a network already described in previous works in this work we show how is possible to estimate the distribution of losses for the banking system with our model additionally we show how it is possible to separate the distribution of losses into two components the losses incurred by the initial shock and the losses resulting from the contagion process finally once the distribution is estimated we can derive standard risk measures for the system as a whole another important contribution of this work is that we can follow the evolution of certain risk measures like the expected loss or the cvar in order to evaluate if the system is becoming more or less risky in fact more or less fragile additionally we can decompose the distribution of losses of the whole banking system into the systemic and the contagion elements and we can determine if the system is more prone to experience contagious difficulties during a certain period of time

implementing optimal taxes using tradable share permits abstract this paper presents a simple system for efficient regulation under asymmetric information each firm s income is controlled by a tax that depends on the firm s own output and on a parameter construed as a share permit these shares of total expected output lower a firm s tax burden and are acquired in a competitive market by employing this scheme the planner only requires knowledge of marginal damage to induce the first best outcome relative to a traditional cap and trade approach the system increases expected social welfare

emissions trading electricity restructuring and investment in pollution abatement this paper analyzes an emissions trading program that was introduced to reduce smog causing pollution from large stationary sources using variation in state level electricity industry restructuring activity i identify the effect of economic regulation on pollution permit market outcomes there are two main findings first deregulated plants in restructured electricity markets were less likely to adopt more capital intensive environmental compliance options as compared to regulated or publicly owned plants second as a consequence of heterogeneity in electricity market regulations a larger share of the permitted pollution is being emitted in states where air quality problems tend to be more severe jel l51 l94 l98 q53 q58 when the us federal government first began regulating major sources of air pollution in the 1960s the conventional approach to meeting air quality standards involved establishing maxi mum emissions rates or technology based standards for regulated stationary sources however economists have long maintained that an emissions permit market could more efficiently coor dinate pollution abatement activities provided a series of assumptions are met over the past few decades market based cap and trade cat approaches to regulating emissions from industrial point sources have become a centerpiece of environmental regulation in the united states in the theoretical first best permit market equilibrium the total social cost of meeting an emis sions cap is minimized each firm chooses a level of pollution abatement such that its marginal cost of reducing pollution is set equal to the social marginal benefit from emissions reduction in practice preexisting distortions in product markets that are subject to cat regulation may interfere with the emissions permit market s ability to operate efficiently this paper studies the effects of electricity market regulation on permit market outcomes in the context of a major us emissions trading program the nox budget program the recent wave of electricity industry restructuring in the united states has resulted in significant interstate variation in economic regulation consequently facilities in the same cat program face very different economic regu lation and investment incentives in their respective electricity markets whereas rate base regu lated plants are guaranteed to earn a rate of return on prudent investments in pollution abatement equipment deregulated plants operating in restructured electricity markets are offered no such

stability analysis of financial contagion due to overlapping portfolios abstract common asset holdings are widely believed to have been the primary vector of contagion in the recent financial crisis we develop a network approach to the amplification of financial contagion due to the combination of overlapping portfolios and leverage and we show how it can be understood in terms of a generalized branching process this can be used to compute the stability for any particular configuration of portfolios by studying a stylized model we estimate the circumstances under which systemic instabilities are likely to occur as a function of parameters such as leverage market crowding diversification and market impact although diversification may be good for individual institutions it can create dangerous systemic effects and as a result financial contagion gets worse with too much diversification there is a critical threshold for leverage below it financial networks are always stable and above it the unstable region grows as leverage increases note that our model assumes passive portfolio management during a crisis however we show that dynamic deleveraging during a crisis can amplify instabilities the financial system exhibits robust yet fragile behavior with regions of the parameter space where contagion is rare but catastrophic whenever it occurs our model and methods of analysis can be calibrated to real data and provide simple yet powerful tools for macroprudential stress testing

transaction costs and tradeable permits abstract tradeable permit systems are at the center of current interest and activity in market based reforms of environmental policy because these systems can offer significant advantages over conventional approaches to pollution control unfortunately claims made for their relative cost effectiveness have often been exaggerated transaction costs which may be significant in these markets reduce trading levels and increase abatement costs in some cases equilibrium permit allocations and hence aggregate control costs are sensitive to initial permit distributions providing an efficiency justification for politicians typical focus on initial allocations

do energy efficiency investments deliver evidence from the weatherization assistance program a growing number of policies and programs aim to increase investment in energy efficiency because conventional wisdom suggests that people fail to take up these investments even though they have positive private returns and generate environmental benefits many explanations for this energy efficiency gap have been put forward but there has been surprisingly little field testing of whether the conventional wisdom is correct this article reports on the results of an experimental evaluation of the nation s largest residential energy efficiency program the weatherization assistance program conducted on a sample of approximately 30 000 households in michigan the findings suggest that the upfront investment costs are about twice the actual energy savings furthermore the model projected savings are more than three times the actual savings although this might be attributed to the rebound effect when demand for energy end uses increases as a result of greater efficiency the article fails to find evidence of significantly higher indoor temperatures at weatherized homes even when accounting for the broader societal benefits derived from emissions reductions the costs still substantially outweigh the benefits the average rate of return is approximately 7 8 annually

credit markets with differences in abilities education distribution and growth this article presents an endogenous growth model in which credit markets affect time allocation of individuals with different educational abilities credit markets allow the more able to specialize in studying and the less able to specialize in working this specialization can increase growth and welfare this article also shows that in economies with high low levels of education abilities the opening of credit markets induces a more disperse equal income distribution the role of intergenerational transfers in overcoming the absence of credit markets is also discussed as well as other forms of credit markets imperfections

liquidity coinsurance moral hazard and financial contagion we study the propagation of financial crises between regions characterized by moral hazard problems the source of the problem is that banks are protected by limited liability and may engage in excessive risk taking the regions are affected by negatively correlated liquidity shocks so that liquidity coinsurance is pareto improving the moral hazard problem can be solved if banks are sufficiently capitalized under autarky a limited investment is needed to achieve optimality so that a limited amount of capital is sufficient to prevent risk taking with interbank deposits the optimal investment increases and capital becomes insufficient to prevent excessive risk taking thus bankruptcy occurs with positive probability and the crises spread to other regions via the financial linkages opening the financial markets is nevertheless pareto improving consumers benefit from liquidity coinsurance although they pay the cost of excessive risk taking finally we show that in this framework a completely connected deposit structure is more conducive to financial crises than an incompletely connected structure

multiple pollutants uncovered sectors and suboptimal environmental policies in our analytical general equilibrium model where two polluting inputs can be substitutes or complements in production we study the effects of a tax on one pollutant in two cases one where both pollutants face taxes and the second where the other pollutant is subject to a permit policy in each case we solve for closed form solutions that highlight important parameters we demonstrate two important ways that environmental taxes and permits are not equivalent first the change in the pollutant facing a tax increase depends on whether the other pollutant is subject to a tax or permit policy second if that other pollutant is subject to a tax then general equilibrium effects can increase or decrease its quantity affecting overall welfare however when the second pollutant is subject to a permit policy that binds then welfare is not affected by this spillover effect finally a numerical exercise helps demonstrate these two ways that taxes and permits differ using the example of coal fired power plants our numerical exercise examines the impacts of increasing a hypothetical carbon tax on the quantity of sulfur dioxide emissions don fullerton department of finance university of illinois bif box 30 mc520 515 east gregory drive champaign il 61820 and nber dfullert illinois edu daniel h karney department of economics university of illinois david kinley hall champaign il 61820 dkarney2 illinois edu in a simple model with multiple pollutants the first best can be achieved either by a tax on each pollutant or equivalent permit price that reflects each marginal environmental damage that is the first best requires each pollutant to be optimally regulated not all pollutants are regulated however and even regulated ones likely face suboptimal policy the multiple pollutant setting creates complications for regulators tightening rules on one pollutant changes how firms value other pollutants thus a regulator concerned with social welfare who can change only one policy needs to account for changes across multiple pollutants for example policymakers who adopt a new carbon policy may not be able to adjust each regulation on other types of pollution especially where different laws and jurisdictions govern the different pollutants our model is general enough to represent any industry with multiple pollutants that are substitutes or complements so a price increase on one can induce firms to increase or decrease other pollutants for example sigman 1996 studies chlorinated solvents used for metal cleaning and degreasing and she finds that raised disposal costs for liquid chemical wastes may lead to more air emissions i e substitutes ren et al 2011 find that reducing co2 by use of biofuel can increase nitrogen runoff from farms our numerical example below involves coal fired electric power plants that emit both carbon dioxide co2 and sulfur dioxide so2 agee et al 2014 describe four ways these two pollutants could be substitutes or complements they find that reducing nox has substantially reduced so2 and co2 while reducing so2 has substantially increased co2 p 66 our illustration uses the u s epa assumption that a carbon tax reduces use of coal and therefore both pollutants i e complements a permit policy limits so2 from power plants under the u s acid rain program arp which has received much academic attention if co2 were to be regulated by a 1 in fact studies of a particular environmental regulation often include ancillary benefits from the reduction of other pollutants see burtraw et al 2003 groosman et al 2011 and kolstad et al 2014 2 yet greenstone 2003 finds little evidence that the clean air act increased water or ground pollution gamper rabindran 2006 finds that off site recycling is a substitute for chemical waste disposal while fare et al 2012 find that nox and so2 are substitutes in production at power plants 3 in response to so2 controls the switch to low sulfur coal with lower heat rate could increase co2 per kilowatt hour also desulfurization equipment uses electric power that requires burning more coal and may generate added co2 emissions from the chemical reactions that capture so2 if the response is to shut down dirty plants then effects on co2 depend on whether new plants use coal or natural gas 4 see schmalensee et al 1998 burtraw et al 1998 and carlson et al 2000 the arp s cap on so2 is not currently binding so the permit price is zero starting in 2011 to explore the general problem of interactions between pollution policies our numerical exercises use positive so2 prices from 2007 data

distributional weights in environmental valuation and cost benefit analysis theory and practice abstract cost benefit analysis cba is built on the kaldor hicks efficiency criterion whereby projects that have aggregate positive net benefits are recommended even if those who lose are not compensated for their losses two kinds of problems can be identified with the use of the criterion first as income tends to affect monetary welfare changes positively the preferences of those with higher wealth have a larger weight in societal decision making second monetary welfare changes can be thought of as changes in real income which matter more for those with a lower initial wealth level both problems can be mitigated with distributional weighting despite their strong theoretical pedigree distributional weights have been largely neglected in practical cbas one exception being analyses in climate change economics we present the theory of distributional weighting and illustrate how weights can be applied empirically in an international environmental cba that deals with marine water quality improvements we show that different weighting schemes can result in different policy recommendations we also show that taking the income distribution within countries into account can change a country s willingness to participate in the water quality improvement program and that the income elasticity of willingness to pay wtp is an important indication of the direction of change

government failure and market failure on the inefficiency of environmental and energy policy in this article we describe some important themes in energy and environmental policy there are two main reasons for our interest in these policies first such policies will likely be important in the coming decades as issues related to climate change and energy security come to the fore second there are important lessons to be learned from a careful review of the actual performance of energy and environmental policies we undertake a selective survey of the literature to highlight what is known about the efficiency of particular kinds of policies laws and regulations in these areas this paper makes three key contributions the first is to synthesize a large literature on energy and environmental policy in a way that can be easily digested by both non experts and experts the second contribution is to suggest that if history is a guide then we should not expect many interventions in these policy areas to come close to maximizing net economic benefits the third is to suggest what might be needed for the development of more efficient energy and environmental policies copyright 2010 oxford university press

economic ideas for a complex climate policy regime abstract the parsimony of economic theory provides general insights into an otherwise complex world however the most straightforward organizing principles from theory have not often taken hold in environmental policy or in the decentralized climate policy regime that is unfolding one reason is inadequate recognition of a variety of institutions this paper addresses three ways that the standard model may inadequately anticipate the role of institutions in the actual implementation of climate policy with a u s focus multilayered authority across jurisdictions the impressionistic rather than deterministic influence of prices through subsidiary jurisdictions and the complementary role of prices and regulation in this context the economic approach is built on the premise that incentives affect behavior we suggest that an important pathway of influence for economic theory is to infuse incentive based thinking into the conventional regulatory framework in a complex policy regime incentives can be shaped by shadow prices as well as market prices

generalized progress of abatement technology incentives under environmental liability law this paper considers the incentives environmental liability creates to improve pollution abatement technology our analysis considers technical progress in end of pipe abatement and in the production technology used thereby generalizing the approach taken by endres et al environ resour econ 36 341 366 2007 we establish that this generalization has drastic repercussions on incentives under negligence liability while the performance of strict liability is not compromised furthermore it is demonstrated that the social desirability of investment in abatement or production technology or both decisively determines how ex ante and ex post regulation fare with respect to welfare maximization in the case of negligence liability

technology adoption under time differentiated market based instruments for pollution control abstract peak concentrations of ground level ozone pose health risks to millions of u s citizens across the u s in order to reduce peak ozone concentrations nitrogen oxide nox emissions from the power sector among others have been regulated with technology based standards or more commonly in recent years market based instruments such as cap and trade programs however the lack of temporal flexibility in current designs of these market based instruments limits their cost effectiveness on days forecasted to have the highest levels of pollution including ozone precursors such as nox and as further emission reductions are sought the marginal cost of these approaches increases dramatically in this paper we compare three regulatory schemes for reducing nox emissions on high ozone days time differentiated pricing which prices nox emissions only on days with high ozone concentrations undifferentiated pricing which represents current nox emission regulations and technology based standards we develop a novel model that captures for the first time both the short and long term response of generators through redispatching and control technology adoption to a dynamic pricing scheme such as time differentiated pricing unlike prior studies on time differentiated pricing the heart of our model a unit commitment model accounts for inter temporal constraints on power generation that may be crucial to accurately capturing the response of generators to a transient price signal we apply this model to the texas power system and find that while control technology adoption specifically selective catalytic reduction does occur at very high time differentiated prices time differentiated pricing mainly affects emissions and costs through redispatching of gas for coal fired generation furthermore we show that time differentiated pricing due to its targeted pricing mechanism provides a more cost effective approach than undifferentiated pricing or technology based standards for reducing nox emissions on high ozone days but is not cost effective at reducing summer wide nox emissions our results illustrate the trade offs between these regulatory approaches and suggest that states should consider dynamic pricing schemes such as time differentiated pricing for achieving further reductions in peak ozone concentrations

the effects of fiscal stimulus evidence from the 2009 cash for clunkers program we evaluate the impact of the 2009 cash for clunkers program on short and medium run auto purchases our empirical strategy exploits variation across u s cities in ex ante exposure to the program as measured by the number of clunkers in the city as of summer 2008 we find that the program induced the purchase of an additional 370 000 cars in july and august 2009 however we find strong evidence of reversal high clunker counties bought fewer autos in the 10 months after the program expired which offset most of the initial purchases we find no evidence of an effect on employment house prices or household default rates in cities with higher exposure to the program jel codes h20 e62 copyright 2012 oxford university press

efficient pollution regulation getting the prices right this paper argues for efficient environmental regulations that equate the mar ginal damage of pollution to marginal abatement costs across space the paper estimates the source specific marginal damages of air pollution and calculates the welfare gain from making the current sulfur dioxide allowance trading pro gram for power plants more efficient the savings from using trading ratios based on marginal damages are between 310 and 940 million per year the potential savings from setting aggregate emissions efficiently and from includ ing more sources of air pollution are many times higher jel h23 q53 q58

emission trading in europe with an exchange rate this paper explores the analytical and empirical properties of a new method for emission trading according to a fixed exchange rate the exchange rate is based on the ratios of the marginal costs of abatement in the optimal solution in order to account for the impact of the location of emission sources on the deposition it is shown that generally this system will not achieve the optimal solution and does not guarantee that environmental deposition constraints are not violated although total abatement costs are always reduced a routine was developed to mimic trading as a bilateral sequential process subject to an exchange rate in the example used results for so2 emissions in europe show that starting from a uniform reduction exchange rate trading achieves higher cost savings than one to one trading without achieving the cost minimum sulfur deposition targets are not violated since the initial emission allocation overfulfilled targets at many places the results are sensitive to pre trade emission levels the transaction costs the availability of information on potential cost savings and assumptions made on the behavior of trading partners

financial contagion and economic development an epidemiological approach abstract we develop an epidemiological approach to analyze how financial contagion may affect and be affected by economic activity we show that according to specific parameter values the economy may converge either to a non speculative or to a speculative equilibrium in the former situation the level of per capita income is maximal while in the latter it is reduced by financial contagion the presence of economic and financial feedback effects may also give rise to macroeconomic fluctuations during the transitional path clearly showing that such economic and financial links are an important driver of the short run macroeconomic performance by extending the analysis to a spatial dimension we also show that financial contagion in some specific region may propagate quickly also in regions far away from those in which the contagion initially occurs highlighting the role of regional policy coordination to avoid interregional contagion

efficient pollution regulation getting the prices right comment the cost effectiveness of cap and trade emissions regulations has become widely accepted a 2009 proposal by muller and mendelsohn would replace conventional ton for ton trading with trading based on estimates of marginal damages by pollutant and by source this proposal faces difficulties arising from the negative marginal damage estimates neglected in muller and mendelsohn 2009 for nitrogen oxide no x emissions from many urban counties such estimates imply nonconvexities in air chemistry that complicate trading and could result in trades that increase emissions by both buyer and seller uncertainty in source specific damages also creates rent seeking opportunities and the potential for costly litigation jel h53 q53 q58

the effectiveness of incomplete and overlapping pollution regulation evidence from bans on phosphate in automatic dishwasher detergent abstract this paper examines the effectiveness of command and control policies in the presence of incomplete and overlapping regulations we study how recent bans on phosphate in household dishwasher detergent affect pollution loads to waterways costs at wastewater treatment facilities and consumer behavior we show that the effectiveness of the bans in reducing effluent depends critically on regulations at receiving treatment facilities as cost minimizers facilities with an emissions standard on phosphorus face no incentive to deviate from the standard we show that bans have weak effects on effluent especially in the most polluted waterways we also use an early isolated ban in spokane washington to study the effect of the bans on consumers we find that this ban shifted approximately 40 of dishwasher detergent sales from spokane to bordering counties until a state wide ban was implemented using these estimates we find that the welfare loss to consumers from recent bans is likely greater than the cost savings to treatment plants
