reforms of environmental policies in the presence of cross border pollution and public private clean up we construct a two country model where pollution from production is transmitted across borders pollution abatement is undertaken by both private producers and the public sector we characterize nash optimal levels of the policy instruments in the two countries emission taxes and funds allocated for public abatement activities we examine the implications of a number of multilateral policy reforms one of our findings is that the magnitude of the beneficial effect of a reform depends on the scope of the reform if it is restricted to a subset of policy instruments then the efficacy of environmental policy reform can be greatly undermined

day of the week effects and asset returns the number of empirical studies using daily stock returns is rapidly increasing researchers generally assume that the distribution of stock returns is identical for all days of the week a convenient statistical assumption but not a necessary condition of market equilibrium nevertheless there are reasons to suspect that the distribution of returns may vary according to the day of the week the most obvious is the impact of weekends on monday s return since monday s return is calculated over three instead of one calender day the mean and variance may well be higher on monday compared with any other daily return perhaps three times as large previous research has examined the daily distribution of stock returns for a monday effect while fama 1965 does not compare daily mean returns he does report that monday s variance is about 20o greater than other daily returns with a traditional distributional assumption regarding the returns on a financial asset specifies that the expected returns are identical for all days of the week contrary to this plausible assumption this paper discovers that the expected returns on common stocks and treasury bills are not constant across days of the week the most notable evidence is for monday s returns where the mean is unusually low or even negative several explanations of the results are investigated but none proves satisfactory aside from documenting significant day of the week effects the implications of the results for tests of market efficiency are examined while market adjusted returns continue to exhibit day of the week effects these effects are no longer concentrated on monday during the last year we have had many conversations with our colleagues throughout the professions we are particularly thankful to the participants at sessions of the western and american finance associations where preliminary versions of this paper were presented special thanks are due to gene fama gailen hite jon ingersoll robert jarrow merton miller clifford smith and rex thompson the expert research assistance of frank rabinovitch and youngsup yun is gratefully acknowledged 1 the list of papers using daily stock returns is too long to name recent examples include charest 1978 dodd 1980 banz 1981 and reinganum 1981

do better schools matter parental valuation of elementary education the evaluation of numerous school reforms requires an understanding of the value of better schools given the difficulty of calculating the relationship between school quality and student outcomes i turn to another method and use house prices to infer the value parents place on school quality i look within school districts at houses located on attendance district boundaries houses then differ only by the elementary school the child attends i thereby effectively remove the variation in neighborhoods taxes and school spending i find that parents are willing to pay 2 5 percent more for a 5 percent increase in test scores this finding is robust to a number of sensitivity checks

the effect of contemporaneous reserve accounting on the market for federal funds abstract this paper evaluates the effect of the transition from lagged to contemporaneous reserve accounting for the determination of bank reserve requirements through its impact on the market for federal funds the results indicate that increased target reserve uncertainty resulting from the implementation of the contemporaneous reserve accounting system cra caused an initial increase in intraday federal funds rate variance and daily interest rate differences however subsequent to a learning period intraday variance appears to be less pronounced and daily differentials appear to be narrower than under the previously used lagged reserve accounting system lra these results are attributed to the lengthening of the accounting period from one to two weeks therefore while not costless the new system does not appear to have seriously disrupted the federal funds market

hedonic estimation applied to a water rights market rights is concerned with the efficiency of water allocations where there are legal and institutional constraints on water rights trades economists have argued that such constraints prohibit water from moving to its socially highest valued uses and hence that the allocation of water under these restrictions is inefficient on the other hand if water rights associated with a certain parcel of farm real estate could be sold separately from the land in a perfectly competitive market the allocation of water would be efficient hirshleifer et al 1969 42 43 anderson 1983 1 the past attempts to examine and compare the efficiency of water rights markets have been qualitative one notable example is the study by brown et al 1982 which hypothesized that water rights markets are more efficient in regions where water is relatively scarce six basins were examined and as

do safeguard tariffs and antidumping duties open or close technology gaps abstract this paper examines how the country breadth of tariff protection can affect the technology adoption decisions of both domestic import competing and foreign exporting firms the contribution of the analysis is to show how firm level technology adoption changes under tariffs of different country breadth i show that a country specific tariff like an antidumping duty induces both domestic import competing firms and foreign exporting firms to adopt a new technology earlier than they would under free trade in contrast a broadly applied tariff like a safeguard can accelerate technology adoption by a domestic import competing firm but will slow down technology adoption by foreign exporting firms because safeguard tariffs can delay the foreign firm s adoption of new technology the worldwide welfare costs associated with using them may be larger than is generally believed

tariffs versus quotas in the presence of imperfect competition and cross border externalities we consider trade policies intended to affect the production of a foreign monopolist that generates negative externalities we derive the optimal tariff and optimal import quota and examine which policy measure should be used to maximize domestic welfare we find that if the domestic government does not have full information on the foreign firm s production method and if cross border externalities exist import quotas are in some cases preferable to tariffs otherwise however tariffs are preferable to quotas jel classification f13 f18 droits de douane versus contingentements quand il y a concurrence imparfaite et effets externes trans frontaliers les auteurs examinent les politiques commerciales qui veulent affecter la production d un monopoleur etranger qui engendre des effets externes negatifs on definit le droit de douane optimal et le contingentement optimal des importations et on determine quelle politique devrait etre utilisee pour maximiser le niveau de bien etre au niveau national il appert que si le gouvernement national n a pas une information complete sur les methodes de production de la firme etrangere et si les effets externes traversent les frontieres un contingentement des importations est preferable dans certains cas a des droits de douanes autrement cependant les droits de douane constituent la solution preferable

endogenous international joint ventures and the environment abstract this paper examines the welfare effects of emission taxes under a choice between an international joint venture jv and a full ownership fdi foreign direct investment by parent firms from a developed country the north and a developing country the south as well as their location and share decisions if the south has a poor abatement technology its best policy is to impose a relatively high emission tax to attract a full ownership fdi if it has a good abatement technology the best policy is to impose a relatively low emission tax to attract the jv furthermore deregulation of foreign ownership of the jv improves the quality of the environment

equilibrium pollution taxes in open economies with imperfect competition abstract this paper argues that imperfect competition in global markets creates a strategic interaction between governments that can lead to the inefficient distortion of pollution taxes this distortion can be decomposed into a rent capture effect and a pollution shifting effect the rent capture effect lowers equilibrium taxes as each country attempts to gain a competitive advantage over its trading partner and thereby capture foreign rent through net exports the pollution shifting effect raises equilibrium taxes as each country attempts to transfer production and its associated pollution to the other country this effect vanishes if pollution is perfectly transboundary because shifted pollution causes as much damage to the domestic environment as does domestic pollution the net effect on symmetric equilibrium taxes is negative except in the special case of perfect competition with no transboundary pollution in this case the two effects are mutually offsetting and the nash equilibrium is efficient when pollution is at least partially transboundary there also arises the usual transboundary externality and this reinforces the negative net strategic effect giving rise to equilibrium taxes that are lower than what is globally efficient

optimal tariffs and the choice of technology discriminatory tariffs vs the most favored nation clause abstract we compare the effects of optimal tariffs on the technology choice of exporters under the discriminatory tariffs regime and the most favored nation mfn clause it is shown that a lower marginal cost mc technology will be chosen in equilibrium under the mfn clause as a result the importing country s long run welfare increases with the adoption of mfn while in most cases the exporting countries welfare decreases however ex post technology choice the importing country prefers discriminatory tariffs this result therefore highlights the role of mfn as a commitment mechanism to resolve a time inconsistency problem facing the importing country

international trade and environmental quality a survey abstract international trade has been incorporating various aspects of environmental issues since 1970 the extent to which environmental problems might affect many facets of trade or vice versa has been the subject of considerable debate over these years in this article we have attempted to establish some of the links between international trade and environmental quality by performing a comprehensive literature review we discuss issues such as establishing direct and indirect effects of international trade on environmental quality effects of trade on economic development environmental quality and energy and their relation with each other and finally the role of governments and international organizations in this context studies have so far revealed some linkages between trade and environment through conventional trade theory however interactions between international trade and types of pollution their sink and assimilative capacity need to be analyzed using a general equilibrium approach currently very little knowledge and agreement on the nature of interactions between trade theories development process and environmental quality exist existing studies have shown that the structure of environmental regulations should be modified to reflect the existence of trade under imperfect competition therefore further research on the interaction between new trade theory and environmental regulation is needed also theoretical and quantitative analysis regarding the effects of environmental regulations on competitiveness and location decision is needed the intensity and type of environmental measures vary across issues and countries therefore harmonizing environmental measures creates an inefficient atmosphere and to assume that trade restrictions will either improve or reverse the environmental damages is a serious mistake given the dynamic and intricate nature of the problem trade and environment debate continues despite vast research and poses a challenge for researchers and policy makers in the foreseeable future

coordinating climate and trade policies pareto efficiency and the role of border tax adjustments abstract this paper explores the role of trade instruments in globally efficient climate policies focusing on whether or not some form of border tax adjustment bta is warranted when carbon prices differ internationally the analysis shows that while there is no case for bta when all instruments can be freely deployed pareto efficiency does require a form of bta when carbon taxes in some countries are constrained its purpose then is to partly counteract the impact on emissions of inappropriate carbon pricing there or equivalently to undo the trade distortions such pricing creates the required form of bta is generally complex but a special case is identified in which it optimally has the simple structure envisaged in practical policy discussions it is also shown that the efficiency case for bta depends critically on whether climate policies are pursued by carbon taxation or by cap and trade

on the effects of unilateral environmental policy on offshoring in multi stage production processes in the last decades supply chains emerged that stretch across many countries this has been explained with decreasing trade and communication costs we extend the literature by analyzing if and how unilateral environmental regulation induces offshoring to unregulated jurisdictions we first apply an analytical partial equilibrium model of a two stage production process that can be distributed between two countries and investigate unilateral emission pricing and its supplementation with border carbon taxes to get a more comprehensive picture we subsequently apply a computable general equilibrium model that includes a better representation of international supply chains we find heterogeneous but mostly positive effects of a unilateral carbon emission reduction by the european union on the degree of vertical specialisation of european industries and explain these differences by heterogeneity in the emission intensity and pre policy vertical specialisation of sectors border taxes are successful in protecting upstream industries but with negative side effects for downstream industries

international trade and the environment policy reform in a polluted small open economy abstract this paper investigates sufficient conditions for welfare improving policy reforms in a small open economy facing many trade and pollution distortions we investigate and compare reform in tax regimes quota regimes and mixed regimes where some pollutants are regulated with taxes and others with quotas it is also shown that the welfare benefits of reforming pollution policy are greater in an economy with international factor mobility than in an economy not subject to such mobility

tariffs and the adoption of clean technology under asymmetric information this paper examines the effect of a tariff on the decision of a foreign monopolist to adopt clean technology which reduces the flow of a negative cross border externality the clean technology increases the marginal cost of production relative to the dirty technology but only the firm knows the extent of the increase under complete information despite its protectionist motivation the importing country s optimal tariff induces the firm to adopt the clean technology if and only if it is globally efficient to do so under incomplete information this efficiency property is disrupted and the firm biases its choice in favour of dirty technology jel classification f13 f18 ce memoire examine l effet d un tarif douanier sur la decision d un monopoleur etranger d adopter une technologie qui reduise le flux d effets externes negatifs a travers la frontiere la technologie propre accroit le cout marginal de production par rapport a ce qu il serait avec une technologie salissante mais seule l entreprise connait la taille de cet accroissement en regime d information complete malgre ses motivations protectionnistes le tarif optimal du pays importateur entraine l entreprise a adopter la technologie propre si et seulement si c est globalement efficient de le faire en regime d information incomplete cette propriete est perturbee et l entreprise tend a faire ses choix en faveur de la technologie salissante

will u s agriculture really benefit from global warming accounting for irrigation in the hedonic approach will u s agriculture really benefit from global warming accounting for irrigation in the hedonic approach wolfram schlenker w michael hanemann and anthony c fisher there has been a lively debate about the potential impact of global climate change on u s agriculture most of the early agro economic studies predict large damages see for example richard m adams 1989 harry m kaiser et al 1993 and adams et al 1995 in an innovative paper robert mendelsohn william d nordhaus and daigee shaw 1994 hereafter mns propose a new approach using the variation in temperature and precipitation across u s counties to estimate a reduced form hedonic equation with the value of farmland as the dependent variable a change in temperature and or precipitation is then associated with a change in farmland value which can be interpreted as the impact of climate change adams et al 1998 characterize the hedonic approach as a spatial analogue approach and acknowledge that the strength of the spatial analogue approach is that structural changes and farm responses are implicit in the analysis freeing the analyst from the burden of estimating the e ects of climate change on particular region speci c crops and farmer responses on the other hand one of the potential disadvantages of the hedonic approach is that it is a partial equilibrium analysis i e agricultural prices are assumed to remain constant 1 while year to year uctuations in annual weather conditions certainly have the potential to impact current commodity prices especially for crops produced only in a relatively localized area such as citrus fruits which are grown mainly in california and florida changes in long run weather patterns i e changes in climate might have a smaller e ect on commodity prices because of the greater potential for economic adaptation particularly shifts in growing regions 2 the hedonic approach as implemented by mns predicts that existing agricultural land on average might be more productive and hence result in bene ts for u s farmers 3 the hedonic approach has received considerable attention in our judgment in part because the conclusions are at variance with those of some other studies

trade transboundary pollution and foreign lobbying in this paper we explore the use of trade policy in addressing transboundary stock pollution problems such as acid rain and water pollution we show that a tariff determined by the current level of accumulated pollution can induce the time path of emissions optimal for the downstream polluted country but if the upstream polluting country can lobby the downstream government to impose lower tariffs distortions brought by corruption and foreign lobbying lead to a rise in the upstream country s social welfare and to a decrease in social welfare in the downstream country thus the usefulness of trade policy as a tool for encouraging cooperation and internalizing transboundary externalities depends critically on the degree of governments susceptibility to foreign political influence

plant location wind direction and pollution policy under offshoring we examine pollution policy in a unified three country framework with the country in the middle playing double roles as both a polluter and a victim we find that government preference over profits and consumer surplus to be important and so is environmentalism in particular the most downwind country has the least incentives to control pollution under oligopoly several additional undesirable scenarios may arise due to the interaction between wind direction and the incentive trade offs in rent shifting and pollution control we analyse the mechanisms behind and provide policy guidance

which hedonic models can we trust to recover the marginal willingness to pay for environmental amenities abstract the hedonic property value model is among our foremost tools for evaluating the economic consequences of policies that target the supply of local public goods environmental services and urban amenities we design a theoretically consistent and empirically realistic monte carlo study of whether omitted variables seriously undermine the method s ability to accurately identify economic values our results suggest that large gains in accuracy can be realized by moving from the standard linear specifications for the price function to a more flexible framework that uses a combination of spatial fixed effects quasi experimental identification and temporal controls for housing market adjustment

the impact of global warming on agriculture a ricardian analysis reply we measure the economic impact of climate on land prices using cross sectional data on climate farmland prices and other economic and geophysical data for almost 3 000 counties in the united states we find that higher temperatures in all seasons except autumn reduce average farm values while more precipitation outside of autumn increases farm values applying the model to a global warming scenario shows a significantly lower estimated impact of global warming on u s agriculture than the traditional production function approach and in one case suggests that even without co sub 2 fertilization global warming may have economic benefits for agriculture 16 refs 5 figs 5 tabs

reserve regulation and recourse as a source of risk premia in the federal funds market abstract in this paper we demonstrate that there is a pronounced and persistent daily pattern of returns in the federal funds market centered on wednesday we present evidence that explains this phenomenon as a reflection of the optimal behavior of banks operating in an environment in which there are effective reserve requirements and a penalty cost for recourse to discount borrowing in particular we report empirical evidence that shows there was a significant upward shift in the amplitude of this pattern of daily returns that resulted from 1 the increase in uncertainty associated with the change in federal reserve operating procedures during the 1979 1982 period and 2 the imposition of a surcharge on discount borrowing instituted by the federal reserve our results demonstrate that what otherwise might be regarded as anomalous interest rate behavior is consistent with the optimal response of banks to the regulatory environment within which they operate

the effects of shifts in monetary policy and reserve accounting regimes on bank reserve management behavior in the federal funds market abstract this paper looks at the effects on fed fund rates and fed fund purchasing behavior of large banks resulting from i the 1982 regime switch from non borrowed to borrowed reserve targeting by the fed and ii the 1984 switch from lagged to almost contemporaneous reserve accounting cra whether we analyse changes in the interest rate or quantity dimensions the shift in monetary policy targets appeared to have had a more profound effect on the market for bank reserves than the shift in reserve accounting regime these results therefore tend to support the contention that a shift to cra by itself will have little effect on bank reserve management behavior unless combined with its logical counterpart a total reserves target

interest rate dispersion and volatility in the market for daily funds abstract the purpose of this paper is to study the determinants of equilibrium in the market for daily funds we use the eonia panel database which includes daily information on the lending rates applied by contributing commercial banks the data clearly show an increase in both the time series volatility and the cross section dispersion of rates towards the end of the reserve maintenance period these increases are highly correlated we design a model to account for these empirical facts our theoretical model shows how the operational framework of monetary policy causes a reduction in the elasticity of the supply of funds by banks throughout the reserve maintenance period this reduction in the elasticity together with market segmentation and heterogeneity is able to generate distributions for the interest rates and quantities traded with the same properties as in the data we also investigate the effects of the changes in the eurosystem s operational framework enacted on march 2004 for interest rate behaviour

a general equilibrium analysis of conjunctive ground and surface water use with an application to morocco groundwater resources gw account for nearly 30 of the world s sustainable water supplies yet this resource which is fraught with externalities has largely been left unregulated the economic literature on gw is predominantly of a partial equilibrium type we analyze gw regulation in a general equilibrium setting focusing on the stabilization value of gw under natural drought and economic rural urban water transfer shocks a general equilibrium approach allows evaluating direct and indirect effects of gw regulation on agriculture and nonagriculture sectors and extends the scope for water policy the analysis is applied to morocco by extending an existing computable general equilibrium cge model to include ground and surface water sw resources we study effects of i an increase in gw extraction cost e g as a result of prolonged extraction beyond natural recharge that lowers the aquifer s water table ii a transfer of sw from rural irrigation to urban domestic use and iii a reduction of water availability due to severe drought we estimate the value of gw and assess the direct partial equilibrium and indirect general equilibrium impacts we find that gw plays a critical role in mitigating the negative effects of these types of shocks

externalities in international trade the case for differential tariffs abstract this paper examines the economic justification for the use of differential tariffs to control for positive and negative externalities embodied in traded products in particular economic efficiency requires that taxes and subsidies should be applied to internalize external costs or benefits it is argued that products such as timber minerals and agricultural products that produce large negative environmental externalities should be differentially tariffed to either provide an incentive to cease destructive practices or provide funding for amelioration examples from the mining and agricultural sectors are used to demonstrate the magnitude of tariffs required to offset the estimated environmental damage products with embedded cultural content are used as examples of exports that may possess positive externalities and should be subject to a subsidy

the profits of power land rights and agricultural investment in ghana we examine the impact of ambiguous and contested land rights on investment and productivity in agriculture in akwapim ghana we show that individuals who hold powerful positions in a local political hierarchy have more secure tenure rights and that as a consequence they invest more in land fertility and have substantially higher output the intensity of investments on different plots cultivated by a given individual corresponds to that individual s security of tenure over those specific plots and in turn to the individual s position in the political hierarchy relevant to those specific plots

international trade rules and environmental cooperation under asymmetric information with asymmetric information about local costs relative to international benefits of direct environmental policy countries will rely too heavily on trade policy in controlling cross border externalities in negotiated agreements the unilateral externality policy chosen before negotiations by an exporter provides a signal about its local cost modifying the information used in negotiations the greater the exporter s incentive to use an externality tax as a second best trade instrument the better the signal consequently exogenous limits on the unilateral use of trade policy in the absence of environmental cooperation can diminish the informational problem and improve the performance of prospective environmental agreements copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

federal funds rate prediction we examine the forecasting performance of a range of time series models of the daily us effective federal funds ff rate recently proposed in the literature we find that i most of the models and predictor variables considered produce satisfactory oneday ahead forecasts of the ff rate ii the best forecasting model is a simple univariate model where the future ff rate is forecast using the current difference between the ff rate and its target iii combining the forecasts from various models generally yields modest improvements on the best performing model these results have a natural interpretation and clear policy implications

tariffs and environmental taxes in the presence of environmental r d it is generally held that trade liberalization results in less stringent environmental regulations which suggests that policies regulating trade and the environment are positively correlated this paper examines whether this monotonic relationship still holds true when pollution reducing environmental research and development erd ii an environmental tax instrument only and iii both regulatory instruments to correct for distortions relating to trade and the environment we find that if it is not possible to abate pollution completely through er d then the monotonic relationship between tariffs and environmental taxes is sustained however if it is possible to fully abate pollution through er d then the optimal tariff environmental tax may not increase monotonically with taxes tariffs when both environmental taxes and tariffs are employed these two policies may be strategic substitutes a positive relationship between tariffs and environmental taxes may not be applicable

up the average cost curve inefficient entry and the new protectionism abstract a two country model is developed in which each country produces one good with increasing returns the goods being perfect or imperfect substitutes with cournot nash behavior and free entry certain restrictive trade policies have effects opposite to their favorable effect under noentry assumptions import tariffs and export subsidies lead to inefficient entry that raises rather than decreases the average production cost of and price charge by the domestic industry with negative welfare consequences we argue that these predictions of our model are closely consistent with extensive canadian data on entry exit and firms responses to trade liberalization

greenhouse gas emission controls and firm locations in north south trade this paper studies greenhouse gas emission ghg controls in the presence of international carbon leakage through international firm relocation in a new economic geography model with two countries north and south only north sets a target for ghg emissions we compare the consequences of emission quotas and emission taxes under trade liberalization on location of two manufacturing sectors with different emission intensities and degrees of carbon leakage with low trade costs further trade liberalization increases global emissions by facilitating carbon leakage regulation by quotas leads to spatial sorting resulting in less carbon leakage and less global emissions than regulation by taxes

cross border externalities and trade liberalization the strategic control of pollution the authors examine international trade in a commodity whose production creates a negative externality for the importing country and they consider the nations strategic policy choices when they can restrict trade and when they are bound by a free trade agreement when pollution abatement technology is available the exporting country induces its adoption despite national indifference to the externality in order to reduce the tariff in a free trade agreement environmental policy is used to exploit monopoly power in trade an alternative policy instrument a process standard is introduced national competition in controlling emissions leads to very restrictive antipollution measures we examine international trade in a commodity whose production creates a negative externality for the importing country and we consider the nations strategic policy choices when they can restrict trade and when they are bound by a free trade agreement when pollution abatement technology is available the exporting country induces its adoption despite national indifference to the externality in order to reduce the tariff in a free trade agreement environmental policy is used to exploit monopoly power in trade an alternative policy instrument a process standard is introduced national competition in controlling emissions leads to very restrictive anti pollution measures

an embarrassment of riches confronting omitted variable bias and multiscale capitalization in hedonic price models abstract many researchers have addressed concerns of omitted variable bias in hedonic price models through the use of spatial fixed effects we argue that this approach does not consider the biases introduced by effects that overlap the zone of capitalization for nonmarket goods we show this bias can dominate the usual omitted variable bias using data on developer provided open space we control for multiscale capitalization and omitted variables simultaneously by extending the hausman taylor estimator where the panel component of the estimator is defined over repeated transactions within neighborhoods rather than the traditional definition following a unique cross sectional unit through time

the micromechanics of the federal funds market implications for day of the week effects in funds rate variability the federal funds rate arguably is the most important interest rate in the u s capital market because it plays a central role in monetary policy and the term structure this paper examines the micromechanics of the funds market we show that in a continuous market with asynchronous trading regulatory constraints and accounting conventions that focus agents attention on discrete time instants have important implications for the dynamics of trading activity and realized market prices we also exhibit a model of the market that explains observed regularities in the intertemporal behavior of the funds rate

greenhouse gas emission controls in an open economy to examine how greenhouse gas emission controls affect a country s industrial and trade structures this article presents an open economy model that has both ricardian and heckscher ohlin features we specifically compare emission quotas emission taxes and emission standards the patterns of production and trade critically hinge on those policy tools it is shown that a domestic emission control may lead to carbon leakage and may not reduce the world emissions and that emission standards may work as a hidden production subsidy toward an emission intensive industry

between a rock and a hard place a trade theory analysis of leakage under production and consumption based policies without a comprehensive global climate agreement carbon leakage remains a contentious issue consumption based pricing of emissions which could in practice be implemented with a full border tax adjustment bta has been forwarded as an option to increase the effectiveness of unilateral climate policy this paper questions the economic rationale behind this approach using a theoretical 2 times 2 trade model in which leakage occurs through terms of trade effects we show analytically first that consumption based pricing of emissions does not necessarily result in less leakage than production based policies second the sign of the optimal unilateral carbon tariff depends on the carbon intensity differential between the foreign country s exporting and non exporting sectors and not on the differential between home s and foreign s exporting sectors as implied by the full bta approach third based on empirical data for the year 2004 our model implies that full bta applied by the european union on e g imports from and exports to china would by shifting china s production from the export sector with a relatively low carbon intensity towards the more carbon intensive non export sector actually increase leakage

asymmetric tax policy responses in large economies with cross border pollution we build a model of cross border pollution between two large open economies one importing the polluting good and the other exporting it and derive their non cooperative trade and environmental tax policies we show among other things that 1 in response to a bilateral reduction in trade taxes by both countries the former country s optimal policy is to lower its nash emissions tax while the latter s is to raise it and 2 in response to an increase in emissions tax rates by both countries the former country s optimal reaction is to raise its nash import tariff while the latter s is to reduce its nash export tax that is in the present context freer trade leads the exporting country to adopt stricter while the importing country laxer environmental tax policies

day to day monetary policy and the volatility of the federal funds rate we propose a model of the interbank money market with an explicit role for central bank intervention and periodic reserve requirements and study the interaction of profit maximizing banks with a central bank targeting interest rates at high frequency the model yields predictions on biweekly patterns of the federal funds rate s volatility and on its response to changes in target rates and in intervention procedures such as those implemented by the fed in 1994 theoretical results are consistent with empirical patterns of interest rate volatility in the u s market for federal funds

cross border pollution terms of trade and welfare we construct a two good general equilibrium model of international trade for two small open economies where pollution from production is transmitted across borders governments in both countries impose emission taxes non cooperatively within this framework we examine the effect of changes in the degree of cross border pollution on nash emission taxes emission levels and welfare we do so under two scenarios when changes in cross border pollution do not affect domestic pollution non strategic and when they do strategic we also examine the effect of changes in international terms of trade on pollution and welfare when cross border pollution is non strategic

land markets and the value of water hedonic analysis using repeat sales of farmland author s buck s auffhammer m sunding d abstract the lack of robust water markets makes it difficult to value irrigation water because water rights are appurtenant to land it is possible to infer the value of water from observed differences in the market price of land we use panel data on repeat farmland sales in california s san joaquin valley to estimate a hedonic regression equation with parcel fixed effects this controls for sources of omitted variables bias and allows us to recover the value of irrigation water to landowners in our sample we show that a more traditional cross sectional regression results in an artificially low value of irrigation water the author 2014

buy coal and act strategically on the fuel market abstract a coalition of given size fights climate change by a policy of purchasing fossil fuel deposits and it seeks to manipulate the fuel price in its favor assuming that non signatories are price takers in the fuel market harstad 2012 designs a policy of trading deposits that attains efficiency despite the coalition s option to act strategically in the fuel market the deposit transactions constituting that policy include the trade of deposits which the non signatories would have exploited and the coalition will exploit the present paper shows that in a proper subset of economies a simpler policy is also efficient that consists of deposit purchases for preservation only in these economies the coalition is unable to raise its welfare above the level in the benchmark case of fuel price taking in the economies where the efficient policy requires deposit transactions for exploitation the coalition is better off and the non signatories are worse off than in case of price taking

the value of heterogeneous property rights and the costs of water volatility the system of prior appropriation in the western unites states prioritizes property rights for water based on the establishment of beneficial use creating a hierarchy where rights initiated first are more secure i estimate the demand for security in water rights through their capitalization in agricultural property markets in the yakima river basin a major watershed in washington state all water rights are satisfied in an average year so the relative value of secure property rights is a function of water supply volatility and the costs of droughts are predominantly born by those with weak rights in aggregate security in water rights does not capitalize into property values at the irrigation district level however there is heterogeneity in the premium for secure water rights the lack of a premium for district level water security is robust to a variety of econometric methods to account for correlated district unobservables and the null result produces an economically significant upper bound on the value to water security for the district the ability for farmers to adapt to water supply volatility as well as expectations about water markets and government infrastructure investment are leading explanations for the lack of an aggregate premium these explanations are supported by the pattern of heterogeneity in the water security premium

monetary policy implementation and the federal funds rate this paper investigates how the implementation of monetary policy affects the dynamics and the volatility of the federal funds rate since the early 1980s the most important changes in the fed s conduct of monetary policy refer to the role of the federal funds rate target and the reserve requirement system we show that the improved communication and transparency regarding the federal funds rate target has significantly increased the fed s influence on the federal funds rate since 1994 by contrast the declining role of required reserves in the u s has contributed to higher federal funds rate volatility our results suggest that the planned introduction of remunerated reserves will further enhance the controllability of the federal funds rate

optimal environmental border adjustments under the general agreement on tariffs and trade a country choosing to adopt border carbon adjustments based on embodied emissions is motivated by both environmental and strategic incentives we argue that the strategic component is inconsistent with commitments under the general agreement on tariffs and trade gatt we extend the theory of border adjustments to neutralize the strategic incentive and consider the remaining environmental incentive in a simplified structure the theory supports border adjustments on carbon content that are below the domestic carbon price because price signals sent through border adjustments inadvertently encourage consumption of emissions intensive goods in unregulated regions the theoretic intuition is supported in our applied numeric simulations countries imposing border adjustments at the domestic carbon price will be extracting rents from unregulated regions at the expense of efficient environmental policy and consistency with international trade law

regional carbon policies in an interconnected power system how expanded coverage could exacerbate emission leakage abstract interconnected regional electricity markets are often subject to asymmetric carbon policies with partial coverage for co2 emissions while the resulting problem of carbon leakage has been well studied its mitigation has received relatively less attention we devise a proactive carbon policy via a bi level modelling approach by considering the impact of an emission cap that limits the cost of damage from a regional power market in particular a welfare maximising policymaker sets the cap when facing profit maximising producers and the damage costs from their emissions at two nodes a partial coverage policy could degrade maximised social welfare and increase total regional co2 emissions with potential for carbon leakage due to a higher nodal price difference a modified carbon policy that considers co2 emissions from both nodes tightens the cap which increases maximised social welfare and decreases total co2 emissions vis a vis the partial coverage policy albeit at the cost of greater scope for carbon leakage as it causes nodal prices to diverge as a compromise an import coverage policy implemented by california that counts only domestic and imported co2 emissions could alleviate carbon leakage at the cost of lower maximised social welfare with higher total emissions vis a vis the modified coverage policy

is god in the details a reexamination of the role of religion in economic growth summary barro and mccleary 2003 religion and economic growth across countries american journal of sociology 68 760 781 is a key research contribution in the new literature exploring the macroeconomic effects of religious beliefs this paper represents an effort to evaluate the strength of their claims we evaluate their results in terms of replicability and robustness overall their analysis generally meets the standard of statistical replicability though not perfectly on the other hand we do not find that their results are robust to changes in their baseline statistical specification when model averaging methods are employed to integrate information across alternative statistical specifications little evidence survives that religious variables help to predict cross country income differences copyright 2011 john wiley sons ltd

robust policies to mitigate carbon leakage abstract unilateral climate policy induces carbon leakage through the relocation of emission intensive and trade exposed industries to regions without emission regulation previous studies suggest that emission pricing combined with border carbon adjustment is a second best instrument and more cost effective than output based rebating we show that the combination of output based rebating and a consumption tax for emission intensive and trade exposed goods can be equivalent with border carbon adjustment moreover it is welfare improving for a region that implements emission pricing along with output based rebating to introduce such a consumption tax the welfare gain is particularly large if output based rebating is already implemented for a sector that is not much exposed to leakage e g due to uncertainty about exposure or due to lobbying activities thus supplementing output based rebating with a consumption tax constitutes robust policies to mitigate carbon leakage

free trade and global warming a trade theory view of the kyoto protocol this paper demonstrates how three important results in environmental economics true under mild conditions in closed economies are false or need serious amendment in a world with international trade in goods since the three results we highlight have framed much of the ongoing discussion and research on the kyoto protocol our viewpoint from trade theory suggests a re examination may be in order specifically we demonstrate that in an open trading world but not in a closed economy setting 1 unilateral emission reductions by the rich north can create self interested emission reductions by the unconstrained poor south 2 simple rules for allocating emission reductions across countries such as uniform reductions may well be efficient even if international trade in emission permits is not allowed and 3 when international emission permit trade does occur it may make both participants in the trade worse off and increase global emissions

pollution content tariffs environmental rent shifting and the control of cross border pollution this paper considers the optimal unilateral policy for a country that imports a good from a neighbouring country and is harmed by pollution generated during the production of that good if the foreign country has a variable abatement technology then home has an incentive to impose a tax on the pollution content of imports a pollution content tariff foreign regulation of pollution does not eliminate home s incentives to intervene but instead may create rent shifting opportunities by making the right to pollute a scarce asset foreign pollution quotas create rents that the home government can try to extract

transboundary pollution and the gains from trade we analyse the effects of transboundary pollution on trade patterns and welfare in a general equilibrium trade model production in a dirty industry generates pollution that negatively effects productivity both at home and abroad in a clean industry trade may lead to the spatial separation of production but the existence of transboundary pollution can offset the benefits from specialization we present a general model in which the effects of a country s pollution is country specific we analyse particular cases that correspond to an acid rain problem and a problem in which one country has a cleaner technology than the other we also present some results for small open economies to examine the effects of transboundary pollution in the absence of terms of trade effects

public pollution abatement regional capital mobility and tax competition the environmental economics literature has ignored the effects of the interaction among capital mobility private and public pollution abatement and cross border pollution on environmental policies we analyze these effects in the context of a general equilibrium model we find among other things that i when countries are symmetric the presence of public pollution abatement makes nash equilibrium pollution taxes efficient while lump sum taxes remain inefficient and ii when countries are asymmetric both taxes are inefficient and the nash equilibrium pollution taxes depend mainly on the direction of capital mobility factor intensity and the degree of cross border pollution these results indicate that policy cooperation is more important when countries are different

institutional path dependence in climate adaptation coman s some unsettled problems of irrigation districts that emerged in the american west in the late nineteenth and early twentieth centuries in response to aridity to facilitate agricultural water delivery use and trade raise the transaction costs today of water markets these markets are vital for smooth reallocation of water to higher valued uses elsewhere in the economy and for flexible response to greater hydrological uncertainty this institutional path dependence illustrates how past arrangements to meet conditions of the time constrain contemporary economic opportunities they cannot be easily significantly modified or replaced ex post

appropriative water rights and the efficient allocation of resources this paper investigates the allocative efficiency of the appropriative system of water rights within the context of a simplified model of a water using industry at a long run competitive equilibrium for the industry and with a prohibition on the transfer of water rights among firms it is shown that 1 senior appropriators claim and use more water than junior appropriators 2 senior appropriators bear less risk than junior appropriators 3 the allocation of water and diversion capacitie 6among firms is inefficient being dominated by an equal sharing among firms the equal sharing allocation which is pareto optimal when diversion capacities are supplied by a competitive leasing industry can be achieved under the appropriative system if there are competitive markets in water rights and in leases for the use of diversion capacities an application of the coase theorem
