the cost of environmental protection reported expenditures for environmental protection are often cited as an assessment of the burden of current regulatory efforts however the potential for both incidental savings and uncounted costs means that the actual burden could be either higher or lower than these reported values using a production cost model that considers the possible interaction between environmental and non environmental expenditures we directly estimate the dollar for dollar incidental savings uncounted costs arising from a one dollar increase in reported environmental expenditures although recent literature supports the idea that reported expenditures probably understate the actual burden we find no such evidence in the manufacturing sector based on a large panel of plant level data in one industry we find statistically significant overstatement in three others we find no significant deviation in either direction we conclude that although cost estimates are not overstated on average variation and uncertainty exist

designing economic instruments for the environment in a decentralized fiscal system designing economic instruments for the environment when external effects are important markets will be inefficient and economists have considered several broad classes of economic instruments to correct these inefficiencies however the standard economic analysis has tended to neglect important distinctions and interactions between the geographic scope of pollutants the enforcement authority of various levels of government and the fiscal responsibilities of the levels of government for example externalities generated in a particular local area may be confined to the local area or may spill over to other jurisdictions also local governments may be well informed about how best to regulate or enforce pollution control within their jurisdiction but they may not consider the effects of their actions on other jurisdictions finally the existence of locally generated waste emissions affects the appropriate assignment of both expenditure and tax responsibilities among levels of government the standard analysis therefore focuses mainly upon an aggregate or national perspective it typically ignores the possibility that the externality may be created and addressed by local governments and it does not consider the implications of decentralization for the design of economic instruments targeted at environmental problems this paper examines the implications of decentralization for the design of corrective policies that is how does one design economic instruments in a decentralized fiscal system in which externalities exist at the local level and in which subnational governments have the power to provide local public services as well as to choose tax instruments that can both finance these expenditures and correct the market failures of externalities

firm valuation earnings expectations and the exchange rate exposure effect consistent with previous research we fail to find a significant correlation between the abnormal returns of our sample firms with international activities and changes in the dollar we investigate the possibility that this failure is due to mispricing lagged changes in the dollar are a significant variable in explaining current abnormal returns of our sample firms suggesting that mispricing does occur a simple trading strategy based upon these results generates significant abnormal returns corroborating evidence from returns around earnings announcements as well as errors in analysts forecasts of earnings is also provided it is a widely held view that exchange rate movement should affect the value of a firm standard economic analysis implies that the profitability and value of most u s firms with foreign sales or operations abroad should increase decrease with an unexpected depreciation appreciation of the dollar as expected foreign currency cash flows translate into larger smaller u s

the effect of clean water regulation on profitability testing the porter hypothesis previous theoretical research provides opposing arguments regarding the effect of environmental regulation on profitability this study provides empirical evidence on this debated effect by testing the strong version of the porter hypothesis we employ panel data analysis to examine the effect of water regulation as measured by permitted wastewater discharge limits on the profitability of publicly held firms operating within the chemical manufacturing industries we find that tighter water regulation meaningfully lowers profitability by reinterpreting profitability in terms of sales and costs the results demonstrate that tighter water regulation increases costs conditioned on a given level of sales

social cost of environmental quality regulations a general equilibrium analysis the use of cost benefit analysis by federal regulatory agencies has expanded greatly in scope and sophistication unfortunately agencies continue to employ private cost rather than social cost to evaluate environmental quality regulations furthermore general equilibrium impacts and intertemporal effects of regulations are typically not included in the evaluation in this paper we estimate the social cost of environmental quality regulations mandated by the clean air and clean water acts we construct an econometric general equilibrium model of the united states to demonstrate that social cost estimates diverge sharply from private cost estimates we also demonstrate that general equilibrium impacts are significant and pervasive and that intertemporal effects of the regulations heretofore ignored are significant

asymmetric exchange rate exposure theory and evidence abstract this paper tests the hypothesis that exchange rate exposure is asymmetric over appreciation depreciation cycles more specifically it investigates whether returns on nine sector indexes across four major countries are asymmetrically affected by exchange rate movements the results show that in several instances exposure is asymmetric asymmetries are found to be more pronounced in the financial and non cyclical sectors possible theoretical explanations are provided regarding the particular type of exposure found across sectors and countries

the double dividend second best worlds and real world environmental policy abstract the recent series of papers by bovemberg goulder parry and others argue that the double dividend is unlikely to exist because of second best problems they argue that the imposition of environmental tax in an economy already distorted by income taxes will further distort the economy by reducing incentives to supply labor our paper argues that this is not likely to be the case because of the restrictive assumptions made by these models and because of the role of the environment as a factor of production

linear and nonlinear foreign exchange rate exposures of german nonfinancial corporations this paper investigates whether the low significance of the impact of foreign exchange rate risk on firm value reported in previous studies can be explained by the fact that only the linear exposure component has been estimated or that exchange rate indices were used for a comprehensive sample of german firms empirical evidence is presented for the existence of significant linear and nonlinear exposures which can be identified for bilateral as well as multilateral foreign exchange rates the percentage of foreign sales measures of firm liquidity and industry sectors are significant determinants of the exposure

computable general equilibrium model analysis of economywide cross effects of social and environmental policies in chile abstract the analysis of the linkages between development policies and social and environmental variables is a neglected area within the development literature this paper focuses on the key interrelations among the economic social and environmental elements of the sustainable development triangle a thorough review is undertaken of both social and environmental policies in chile underlining important economic growth and reforms using the static cge model ecogem chile the economywide impacts of several environmental social and combined policies are simulated for the chilean economy six different policies are simulated three environmental policies that impose different taxes on pm10 so 2 and no 2 emissions respectively the same tax on pm10 in a context of high unemployment one social policy that increases government transfers to households and a mixed social environmental policy package where the environmental tax on pm10 and the social transfer policy are simulated simultaneously the results show that environmental tax policies may have negative social effects using real disposable income by quintiles as proxy the impacts depend on the use of the new revenues and the status of employment taxing pm10 emission yields better environmental results than taxing so 2 and no 2 social policies do not show negative environmental impacts combined environmental and social policies improve results thus specific compensating social policies would improve environmental policy acceptance while also reducing poverty or strong income distribution disparities the evidence suggests that environmental policies may have social impacts but not vice versa the results show that the ecogem chile model is useful for analyzing systematically and holistically different economywide policies and their impact on the chilean economy winners and losers may be identified as well as the potential magnitude of gains and losses the results obtained are not all straightforward due to indirect effects

is demand for polluting goods manageable an econometric study of car ownership and use in mexico abstract our motivation for estimating a demand system for gasoline and cars is its strategic relevance to policy objectives such as pollution control if demand is responsive to pricing demand reductions for polluting goods will provide an important share of the pollution reductions otherwise cleaner technologies will have to do most of the job we estimate a model of gasoline demand and car ownership in mexico using a panel of annual observations by state key features that we introduce include instrumental variables on differenced data and the treatment of possible dynamics measurement errors in the data and unobserved individual state characteristics we use tests of serial correlation in the a residuals to model the dynamics properly the resulting demand system is quite responsive to pricing even in the short term 0 6 for the own price elasticity of gasoline but we emphasize a medium to long term perspective of 5 10 years as most relevant for policy five to ten year elasticity estimates are in the range of 1 25 to 1 13 applying these elasticity estimates to data on pollution control options for the vehicle fleet in mexico city the costs of reaching a target for pollution reductions would be 45 more expensive if one were not willing to use a demand management instrument such a gasoline tax in the control program

weak complementarity and production abstract this paper describes how weak complementarity a common assumption to characterize consumer preferences for recovering measures of willingness to pay for nonmarketed environmental resources can be used to evaluate the effects of pollution that may affect profits or costs in such cases pollution serves as an externality imposed by third parties on production activities

policy watch government analysis of the benefits and costs of regulation recently congress has shown a greater interest in assessing the economic impact of regulation this interest was driven in part by estimates that federal regulation costs several hundred billion dollars annually in 1996 congress required the director of the office of management and budget to provide estimates of the total annual benefits and costs of individual regulations this essay reviews the increasing use of economic analysis in regulatory decisionmaking critically assesses the first 0mb report and considers how the use of economic analysis can help inform regulatory decisionmaking it argues that policymakers need to address a growing body of evidence that casts doubt on the effectiveness and efficiency of much regulation

price discrimination by u s and german exporters the insensitivity of the u s trade balance to the sharp depreciation of the dollar in the past three years has revived interest in the relationship between exchange rates and the trade balance a central issue in most analyses of the relation between the current account and the exchange rate concerns the price adjustment process the simple integrated competitive market model predicts that local currency prices should change in proportion to the nominal exchange rate for a country too small to influence world prices the relationship between local currency import prices and exchange rates has been referred to as the pass through relationship in the empirical literature in international economics if the proportional relationship between import prices and exchange rates holds pass through is said to be complete accounts of recent u s experience cite the failure of dollar prices of imported goods to rise in proportion to exchange rates i e incomplete pass through as an important factor in explaining the persistence of the trade deficit unfortunately observations on pass through alone provide limited insight into the behavior of markets since incomplete pass through is consistent with at least two fundamentally different paradigms one is the standard competitive model of trade in which the law of one price holds but exchange rate fluctuations are associated with large changes in import demand due to other factors for example if dollar appreciation is correlated with increases in world demand and industry marginal cost is increasing then pass through will be less than complete the other is an imperfectly competitive model in which exporters are capable of price discriminating across destination markets a phenomenon paul krugman 1987 has labeled pricing to market in this model incomplete pass through is typically associated with fluctuations in the markup of price over marginal cost on exports 2 these fluctuations in markups are believed to be countryspecific they do not reflect the behavior of prices to other export destinations both models are plausible explanations of recent u s experience unfortunately it is impossible to distinguish between these competing models using only information on import prices and exchange rates for a single country in order to distinguish between the competing models an empirical analysis of goods prices and exchange rates must be capable of measuring either marginal cost or the markup over marginal cost either of these tasks poses formidable empirical problems much of the empirical literature in industrial organization has been concerned with precisely these issues since markups are an important measure of the competitiveness of industries

an econometric model of production with endogenous improvement in energy efficiency 1970 1995 the purpose of this paper is to introduce a modification of a standard four input production process where energy is used in an inefficient way due to partly unnecessary waste of energy in this production process r d investment is an additional input in order to improve energy efficiency it closes the gap between energy purchased and energy used effectively the more is invested the less is the waste of energy with the cost and benefit of r d investment incorporated in our model of the firm we analyze the impact of an energy tax on r d effort on output and on the waste of energy the model is implemented empirically by choosing a translog cost function and a set of first order conditions using data for the german chemical industry 1970 1995 in a simulation study based on higher energy prices we found outsourcing as the consequent reaction of the firm more material is used and less of energy labor and capital given the unchanged output level there is no indication of a double dividend in terms of environmental improvement as well as higher demand for labor on the industry level calling for a computable general equilibrium approach in order to answer this open question

exchange rate exposure and industry characteristics evidence from canada japan and the usa abstract this paper examines industry level exchange rate exposures for canada japan and the usa measuring exposure by adding the change in the exchange rate to the domestic market model of industry portfolio returns some industries in all three countries display significant exposures moreover for each country the exchange rate is important for explaining industry returns at the economy wide level to explore whether exchange rate exposures are systematically linked to the activities of the industries we model exposure as a function of industry characteristics for all three countries the relation between exposure and industry characteristics is broadly consistent with economic theory jel f3

sectoral and macroeconomic impacts of the large combustion plants in poland a general equilibrium analysis abstract this paper analyses the final incidence of direct costs of implementation of the eu directive on so 2 and no x emission limits for large combustion plants in poland first we simulate a model from a power sector perspective where compliance with the directive appears to be associated only with direct costs second a more realistic market wide perspective is modeled where abatement costs borne by the power sector become the revenues of the sectors supplying abatement technologies and services simulations indicate that if environmental benefits of implementation are unaccounted for the directive would seem to cause a deadweight loss in the economy the overall impact however is likely to be less negative than what the interest groups claim

the foreign exchange exposure of japanese multinational corporations we find that about 25 percent of our sample of 171 japanese multinationals stock returns experienced economically significant positive exposure effects for the period january 1979 to december 1993 the extent to which a firm is exposed to exchange rate fluctuations can be explained by the level of its export ratio and by variables that are proxies for its hedging needs highly leveraged firms or firms with low liquidity tend to have smaller exposures foreign exposure is found to increase with firm size we also find that keiretsu multinationals are more exposed to exchange rate risk than nonkeiretsu firms it is conventional wisdom that exchange rate movements affect both the cash flows of a firm s operations and the discount rate employed to value these cash flows measuring foreign exchange exposure is now a central issue of international financial management and this issue has spawned a considerable amount of research existing empirical evidence on foreign exchange exposure however seems perplexing studies have so far documented a weak link between contemporaneous exchange rate fluctuations and stock returns of u s multinational firms 2 gendreau 1994 finds it difficult and unconvincing that the weak results imply that exchange rate changes have no effect on exporters stock returns bartov arnd bodnar 1994 attribute the observed insignificant relationship between exchange rate changes and st ock returns to probable problems associated with the previous studies samiple selection procedure or to mispricing caused by investors errors in estimat

tightening environmental standards the benefit cost or the no cost paradigm ms ff ichael porter and claas van der linde have written a paper that is interesting and to us at least somewhat astonishing it is a defense of environmental regulation indeed an invitation to more stringent regulation that makes essentially no reference to the social benefits of such regulation this approach contrasts starkly with the methods that economists and other policy analysts have traditionally used when assessing environmental or other regulatory programs the traditional approach consists of comparing the beneficial effects of regulation with the costs that must be borne to secure these benefits for environmental regulation the social benefits include the reductions in morbidity or premature mortality that can accompany cleaner air the enhanced recreational opportunities that can result from water quality improvements the increased land values that might attend the cleanup of a hazardous waste site the enhanced vitality of aquatic ecosystems that might follow reductions in agricultural pesticide use or any of the other potentially significant benefits associated with tighter standards from this benefit cost approach emerges the standard tradeoff discussed in virtually every economics textbook porter and van der linde deny the validity of this approach to the analysis of environmental regulation claiming it to be an artifact of what they see as a static mindset in their view economists have failed to appreciate the capacity of

coupling model of energy consumption with changes in environmental utility abstract this study explores the relationships between metropolis energy consumption and environmental utility changes by a proposed environmental utility of energy consumption euec model based on the dynamic equilibrium of input output economics theory it considers three simulation scenarios fixed technology technological innovation and green building effect it is applied to analyse hong kong in 1980 2007 continual increase in energy consumption with rapid economic growth degraded environmental utility first energy consumption at fixed technology was determined by economic outcome in 1990 it reached a critical balanced state when energy consumption was 22 109 kwh before 1990 x1 22 109 kwh expansion of energy consumption facilitated socio economic development but suppressed environmental benefits second technological innovation strongly influenced energy demand and improved environmental benefits the balanced state remained in 1999 when energy consumption reached 32 33 109 kwh technological innovation dampened energy consumption by 12 99 exceeding the fixed technology condition finally green buildings reduced energy consumption by an average of 17 5 in 1990 2007 they contributed significantly to energy saving and buffered temperature fluctuations between external and internal environment the case investigations verified the efficiency of the euec model which can effectively evaluate the interplay of energy consumption and environmental quality

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

how do federal regulations affect consumer prices an analysis of the regressive effects of regulation this study is the first to measure the impact of federal regulations on consumer prices by combining consumer expenditure and pricing data from the bureau of labor statistics industry supply chain data from the bureau of economic analysis and industry specific regulation information from the mercatus center s regdata database we determine that regulations promote higher consumer prices and that these price increases have a disproportionately negative effect on low income households specifically we find that the poorest households spend larger proportions of their incomes on heavily regulated goods and services prone to sharp price increases while the literature explores other specific costs of regulation noting that higher consumer prices are a probable consequence of heavy regulation this study is the first to provide a thorough empirical analysis of that relationship across industries irrespective of the reasons for imposing new regulations these results demonstrate that in the aggregate the negative consequences are significant especially for the most vulnerable households

environmental policy on the back of an envelope a cobb douglas model is not just a teaching tool abstract to clarify and interpret the workings of a large computable general equilibrium cge model of environmental policy we build an aggregated cobb douglas cd model that can be solved easily and analytically its closed form expressions show exactly how key parameters determine the sign and size of effects from a large new carbon tax on emissions revenue prices output and welfare data and parameters from the detailed dynamic cge model of goulder and hafstead 2018 are used in the cd model to calculate results that can be compared with theirs results from the cd model track aggregates from the large cge model quite closely even though the cd model omits much detail such as the number of sectors intermediate inputs and international trade a cge model is quite useful to generate detailed numerical results and to reflect on particular aspects of environmental policy but the simpler cd model provides a transparent view of exactly how the policy affects key outcomes

foreign exchange exposure of us tourism related firms abstract to date literature on foreign exchange risk has paid a particular attention to multinationals in trade related industries the tourism sector is also sensitive to the exchange rates between travelers home countries and their destinations suspecting that the exposure of domestic tourism related firms to foreign exchange risk results from price elasticity of demand the current study tested the cash flow exposure of sample firms accounting for nonlinearity asymmetry and lagged effects as a result a significant percentage 78 of domestic tourism related firms was found to have significant foreign exchange exposure this study also found that exchange rate exposure for tourism related firms was nonlinear asymmetric and lagged the evidence implied that several tourism related firms are passive regarding their exposure and may face financial burdens caused by demand fluctuations implications and suggestions are presented along with the findings of the study

valuing nature in a general equilibrium abstract we explore the consequences of modeling the demand for environmental quality improvements as a fully integrated part of a general equilibrium demand system in an applied general equilibrium or cge analysis demand for non market goods depends on a full range of relative prices as well as environmental outcomes we simulate the effects of reducing two air pollutants to improve human health and three ecosystem services provided to households the ecosystem services make non separable contributions to household utility we find that willingness to pay measures of use based ecosystem services are impacted by changes in demand for complementary market goods demand for these goods shifts due to pollution reductions that enhance ecosystem services partial equilibrium estimates of these use values can be measured with substantial error if they fail to account for the general equilibrium adjustments caused by pollution over 300 calibrations of the model identify the model features important to these errors we find that effects on ecosystem services associated with non use values have important implications for the feedback effects on use related measures of economic tradeoffs this is due to how our model integrates market and non market effects reflecting the non market services importance to general equilibrium market outcomes

forward markets currency options and the hedging of foreign exchange risk abstract although transactions exposure to foreign exchange risk can be completely hedged in the forward market the same is not true for economic exposure we show that in some cases a portfolio of currency options can be constructed which hedges economic exposure when the firm has ex post production flexibility in the more general case of uncertainty in multiple exchange rates however more elaborate options than those currently available are required to hedge economic risk completely

measuring the environmental consequences of trade policy a nonmarket cge analysis the newly approved gatt trade agreement is likely to focus greater attention on the conflicts between the proliferation of diverse national policies toward environmental quality and the need to maintain competitiveness in world markets virtually all policy evaluations of this conflict have been limited by a significant misspecification in existing models none of the available computable general equilibrium cge models for international trading patterns consistently reflect the effects of environmental resources on consumers preferences the purpose of this paper is to report the first generation of a composite nonmarket and cge model nm cge for the european community the united states japan and a single region for the rest of the world the model incorporates the morbidity and mortality effects of particulates sulfur oxides and nitrogen oxides it uses existing nonmarket valuation estimates freeman with a specification for consumer preferences that allows changes in atmospheric emissions to diffuse in different amounts to

exchange rate variability and the riskiness of u s multinational firms evidence from the breakdown of the bretton woods system abstract we examine the relation between exchange rate variability and stock return volatility for u s multinational firms and decompose this relation into components of systematic and diversifiable risk focusing on two five year periods around the 1973 switch from fixed to floating exchange rates we find a significant increase in volatility of monthly stock returns corresponding to the period of increased exchange rate variability even relative to the increase in stock return volatility for three control samples in conjunction with this increase in total volatility there is also an increase in market risk beta for multinational firms

the effects of pollution taxes on urban areas with an endogenous plant location this paper has integrated space into the effect of a direct pollution control on the pollution damage of heavily populated areas like cbd this integration gives us some new insights into the effectiveness of a pollution tax as a pollution control device when the plant location of the firm is endogenized it is shown that when the plant location is endogenous as pollution taxes become higher the firm moves its plant towards the cbd causing higher pollution damage to the cbd residents if the production function exhibits decreasing returns to scale

evaluating policy interventions with general equilibrium externalities abstract we report on the results of analytical and numerical models that describe the effects of non separable externalities or public goods on public policies with important general equilibrium consequences in the numerical exercise we calibrate a general equilibrium model with non separable air quality benefits in order to measure the excess burden and total net benefits of transportation and energy taxes in the 1995 u s economy the change in the physical level and the economic value in air quality associated with a given policy is a function of the substitution patterns between air quality and market goods that we assume the size of the deadweight loss due to pre existing distortions such as a tax on labor income is substantially affected by these substitution patterns

the exchange rate exposure of u s multinationals this article examines the exposure of u s multinationals to foreign currency risk evidence is presented that the relationship between stock returns and exchange rates differs systematically across multinationals given these results the study focuses on the determinants of exchange rate exposure the comovements between stock returns and the value of the dollar is found to be positively related to the percentage of foreign operations of u s multinationals copyright 1990 by the university of chicago

banning the bulb institutional evolution and the phased ban of incandescent lighting in germany much academic attention has been directed at analysing energy efficiency investments through the lens of behavioural failure these studies have challenged the neoclassical framing of regulation which emphasises the efficiency benefits of price based policy underpinned by the notion of rational individual self mastery the increasing use of a regulatory ban on electric lamps in many countries is one of the most recent and high profile flash points in this dialectic of freedom versus the state in the public policy discourse this paper interrogates this debate through a study of electric lamp diffusion in germany it is argued that neoclassical theory and equilibrium analysis is inadequate as a tool for policy analysis as it takes the formation of market institutions such as existing regulations for granted further still it may be prone to encourage idealistic debates around such grand narratives which may in practice simply serve those who benefit most from the status quo instead we argue for an evolutionary approach which we suggest offers a more pragmatic framing tool which focuses on the formation of market institutions in light of shifting social norms and political goals in our case progress towards energy efficiency and environmental goals

on market equilibrium analysis in this paper we develop the implications of competitive market equilibrium for production and household behavior when some prices are endogenously determined the properties of market equilibrium functions are explored including the effects of pricing policy a slutsky type equation relating compensated and uncompensated market equilibrium functions is derived implications for multimarket welfare analysis are presented focusing on the effects of pricing policy and technical change

technical change and measuring pollution abatement costs an activity analysis framework the cornerstones of studies that estimate the effectof environmental regulations on an economy areestimates of the pollution abatement costs incurred bythe manufacturing and electric utility sectors however there are concerns regarding the accuracy ofthe surveys used to generate these cost estimates this paper demonstrates that technical change tends toresult in an increasing share of pollution abatementcosts being impossible to measure this finding hasimportant implications for estimating the productivityeffects of environmental regulations developingregulatory budgets and data collection effortsrelated to environmental accounting

linear and nonlinear exchange rate exposure abstract this paper presents a new methodological approach to examine exchange rate exposure which takes account of the role of the market portfolio and macroeconomic variables in exposure regressions exchange rate regimes based on periods of depreciation and appreciation and nonlinear exposure within each regime we show that the stock market s own exposure to exchange rates should be taken into account before considering industry exposure in addition we adjust the exchange rate and the stock market for common economy wide factors that are unrelated to exchange rates within this framework we show that exposure to bilateral exchange rates is statistically and economically important and that industries with extensive international trade are more often exposed than industries with low levels of international trade the signs of exposure coefficients in each regime are consistent with the extent to which an industry exports we also show that nonlinear exposure is often statistically and economically significant interestingly there is little evidence that industries are exposed to a currency basket

applied general equilibrium models for energy studies a survey the importance of energy in any economy developed or underdeveloped became clear after the first oil shock in 1973 since then different studies were carried out to formulate energy policies and to study their impact on the economies since energy policy issues are related to various aspects of the economy such as price formation output determination income generation and distribution consumption behaviour government operation etc a coherent and systematic mechanism is required for such analysis by offering such a framework of analysis age models gained popularity among energy modellers in the 1980s the environmental issues have gained importance and the focus shifted towards curbing and containing emissions of environmentally unfriendly gases resulting from the use of energy age models because of their capability to capture the complexities of the economy have found relevance in analysing the economic impacts of controlling pollution and greenhouse gases this paper surveys the literature on such general equilibrium models as applied to energy studies and reports their special features evolution through time as well as their limitations

renewable energy technologies as beacon of cleaner production a real options valuation analysis for liberia abstract the importance of energy consumption for growth and development calls for improved decision support for a sustainable energy transition given africa s dependence on fossil fuels the economic and environmental savings from research development and deployment of renewable energy technologies may be substantial although the benefits of renewable energy technologies research development funding may appear to be low assuming immediate deployment the uncertainty in the non renewable energy price and the flexibility over timing makes research development program more appealing this study develops different scenarios in order to quantify benefits provided by research development funding for renewable power generation in liberia by using real options pricing approach to estimate the value of renewable energy technologies while taking into account the uncertainty of fossil fuel prices and learning by doing in renewable energy technologies the optimal solution shows that renewable energy technologies are economically attractive especially when external costs are internalized however annual research development funding is low and should be raised significantly in order to guarantee the highest possible investment incentives with minimal expenditures the study also hypothesizes that with the likelihood of renewable energy to replace non renewable energy renewable power use in liberia can potentially reduce carbon dioxide emissions by approximately 13 9 by 2015 compared to the 2008 levels the key insight provided by the real options analysis in this study is that while renewable energy may have inherent limitations such as seasonality of supply low energy content and capacity factor issues they still hold a significant amount of value which can only be detected when externalities are internalized thus underscoring the need for external costs related policies

the impact of economics on environmental policy abstract environmental economists have seen their ideas translated into the rough and tumble policy world for over two decades they have witnessed the application of economic instruments to several environmental issues including preserving wetlands lowering lead levels and curbing acid rain this essay examines the impact of the rise of economics in the policy world on the making of environmental policy i focus on two related but distinct phenomena the increasing interest in the use of incentive based mechanisms such as tradable permits to achieve environmental goals and the increasing interest in the use of analytical tools such as benefit cost analysis in regulatory decision making i argue that economists and economic instruments have had a modest impact on shaping environmental health and safety regulation but that economists will play an increasingly important role in the future although the role of economics is becoming more prominent it does not follow that environmental policy will become more efficient this apparent inconsistency can be explained by the political economy of environmental policy

asymmetric corporate exposures to foreign exchange rate changes research examining firms economic exposures to exchange rate movements has not differentiated periods of foreign currency appreciation and depreciation when estimating exposure coefficients recent theoretical developments regarding real options and pricing to market suggest corporate exposures may be asymmetric i e the financial performance impact of a foreign currency appreciation may not be offset by the currency s depreciation our empirical analysis indicates that for the small percentage of u s manufacturing firms exposed to currency appreciations or depreciations their exposures are asymmetric 1998 john wiley sons ltd

product differentiation and oligopoly in international markets the case of the u s automobile industry this paper develops and estimates a model of the u s automobile industry on the demand side a discrete choice model is adopted that is estimated using micro data from the consumer expenditure survey the estimation results are used in conjunction with population weights to derive aggregate demand on the supply side the automobile industry is modelled as an oligopoly with product differentiation equilibrium is characterized by the first order conditions of the profit maximizing firms the estimation results are used in counterfactual simulations to investigate two trade policy issues the effects of the ver and exchange rate pass through

exposure and markups this article examines how to properly specify and test for factors that affect exchange rate exposure starting from theoretical underpinnings and a sample of u s manufacturing industries between 1979 and 1995 we find that 4 of 18 industry groups are significantly exposed to exchange rate movements through the effect of industry competitive structure export share and imported input share on average a 1 appreciation of the dollar decreases the return of the average industry by 0 13 consistent with our model s predictions as an industry s markups fall rise its exchange rate exposure increases decreases exchange rate movements are an important source of risk for a firm they affect a firm s expected cash flows and or change the terms of competition for exporters importers and multinationals hung 1992 estimates that during the 1980s u s manufacturing industries lost approximately 23 billion year or 10 of total profits due to the dollar s movements surprisingly early studies which assume exchange rate exposure to be constant e g jorion 1990 bodnar and gentry 1993 and amihud 1994 find that exchange rates have no effect on the stock returns of u s multinationals exporters or manufacturing industries recently however allayannis 1997 and bodnar dumas and marston 1998 examine time varying exposure of industry returns 1 in particular the former article focuses on the effect the variation of u s industries import and export shares have on exposure while the latter focuses on pass through and exposure in a sample of japanese export oriented industries besides trade shares and pass through exchange rate exposure also depends on the markup of an industry specifically in industries with
