renewable resource economists and policy what differences have we made abstract this paper surveys developments in fisheries economics and fisheries policy over the past half century early work clarified the nature of the economic issues associated with open access laying the groundwork for changes in policies after coastal nations expanded their jurisdictions in 1976 perhaps the most important point made by economists is that property rights matter and that open access conditions create economic as well as biological problems the policy process has begun to create property rights systems although many of the world s fisheries still operate under mixed systems of regulations and open access incentives

capacity choice and the theory of the mine when extraction from mineral deposits is constrained byfixed capacity an r per cent rule holds this deposit specific rule however is more partial than hotelling s rule in that it is followed byprice takers and does not require price to adjust to produce equilibrium toobtain the resource rent to which the rule applies the shadow value ofcapacity must be subtracted from the usual net price i e price lessshort run marginal cost but the shadow value of capacity cannot becalculated from common depreciation formulas an alternative method ofcalculating the shadow values is derived the shadow value of reserves maybe increasing in the level of initial reserves if there are increasingreturns to installing capacity the value of the resource is not equal tothe discounted resource rent

determinants of financial stress in emerging market economies the global financial crisis of 2008 2009 illustrates how financial turmoil in advanced economies could trigger severe financial stress in emerging markets previous studies dealing with financial crises and contagion show the linkages through which financial stress are transmitted from advanced to emerging markets this paper extends the existing literature on the use of financial stress index fsi in understanding the channels of financial transmission in emerging market economies using fsi of 25 emerging markets our panel regression estimates show that not only advanced economies fsi but also regional and nonregional emerging market fsis significantly increase domestic financial stress our findings also suggest that there is a common regional factor significantly affecting domestic fsi in emerging asia and emerging europe furthermore the results from a structural vector autoregression model with contemporaneous restrictions indicate that although a domestic financial shock still accounts for most of the variation in domestic fsi regional shocks play an important role in emerging asia

global financial services and a global single currency abstract the purpose of this paper is to highlight the evolution of financial institutions in the context of increasingly volatile foreign exchange markets the paper discusses the importance of the formation of a single currency in the us in the 19th century and the formation of the euro in the 20th century for reducing volatility in foreign exchange markets that have assisted financial institutions international business expansion the paper also considers some of the key assumptions of an optimal currency theorem such as labour mobility and argues that in the 21st century more comprehensive financial market integration and a single global currency could emerge provided that capital mobility and hence foreign capital flows continue meeting labour in the host countries for production rather than the other way round

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

toward a political theory of the emergence of environmental incentive regulation this article makes some steps toward a formal political economy of environmental policy economists quasi unanimous preference for sophisticated incentive regulation is reconsidered we recast the question of instrument choice in the general mechanism design literature within an incomplete contract approach to political economy we show why constitutional constraints on the instruments of environmental policy may be desirable even though they appear inefficient from a standard economic viewpoint their justification lies in the limitations they impose on the politicians ability to distribute rents insights are provided on the emergence of incentive mechanisms in environmental regulation

liquidity and the dynamic pattern of asset price adjustment a global view abstract global liquidity expansion has been very dynamic since 2001 contrary to conventional wisdom high money growth rates have not coincided with a concurrent rise in goods prices at the same time however asset prices have increased sharply significantly outpacing the subdued development in consumer prices we investigate the interactions between money and goods and asset prices at the global level using aggregated data for major oecd countries our var results support the view that different price elasticities on asset and goods markets explain the observed relative price change between asset classes and consumer goods

the response of worker effort to piece rates we measure the elasticity of worker effort with respect to changes in the piece rate using panel data collected from the payroll records of a british columbia tree planting firm our data contain information on daily worker productivity and the piece rate received over a five month period using a structural model to control for the endogeneity of the piece rate we estimate this elasticity to be approximately 2 14 we also calculate a nonstructural lower bound to this elasticity equal to 0 77 structural estimation also allows us to perform policy experiments and to compare firm profits under alternative compensation systems our results suggest that profits would increase by at least 17 percent were the firm to implement the optimal static contract as predicted by principal agent theory this increase in profits would be due to capturing worker rents after the revelation of private information over ability yet only a negligible proportion of these rents could be captured while inducing workers to reveal ability truthfully suggesting that dynamic considerations were important in determining the firm s actual choice of contract

competition in regional environmental policies when plant locations are endogenous abstract a two region model is presented in which an imperfectly competitive firm produces a good with increasing returns at the plant level production of the good causes local pollution the firm decides whether to maintain plants in both regions serve both regions from a single plant or shut down if the disutility of pollution is high enough the two regions will compete by increasing their environmental taxes standards until the polluting firm is driven from the market alternatively if the disutility from pollution is not as great the regions will usually compete by undercutting each other s pollution tax rates

international pollution control cooperative versus noncooperative strategies abstract international pollution control involving two neighboring countries is modeled as a simple two player dynamic game each country produces a good that is consumed by domestic households production of each consumption good results in emissions of pollutants households in each country derive utility from the consumption of the domestically produced good but incur costs through the total stock of pollution stock externality in this setting we characterize cooperative as well as noncooperative pollution control strategies of the governments of the two countries that maximize the discounted stream of net benefits of a representative consumer it turns out that when the governments are restricted to use linear strategies noncooperative behavior results in overall losses for both countries if on the contrary governments use nonlinear markov perfect strategies and the discount rate is small enough a pareto efficient steady state pollution stock can be supported as a differentiable subgame perfect equilibrium thus the emergence of first best solutions cooperative outcomes does not require any institutional arrangements threats retaliation etc but can be brought about through the use of nonlinear markov perfect equilibrium strategies

the contribution of l c gray to the economic theory of exhaustible natural resources and its roots in the history of economic thought abstract the paper opens with an assessment of natural resources economics up to 1913 14 when gray published his two pioneering articles in natural resources economics part i an in depth study of gray weighing his contribution to the microeconomic theory of the mine and the macroeconomic theory of conservation against current literature constitutes the main body of the paper part ii gray and hotelling s contributions to the theory of the mine are compared part iii the paper concludes with a comparison drawn between the author s findings and the scant attention previously paid to gray s contributions to natural resources economics so far as i know this is the first attempt to apply economic theory to this particular problem of conservation h c taylor unpublished letter to c r van hise may 23 1913 a reference to gray s economic possibilities of conservation

avoiding invasives trade related policies for controlling unintentional exotic species introductions abstract international commodity trade serves as the primary conduit for unintentional introductions of damaging exotic species we use a simple model of contaminated goods trade to analyze the optimal mix of tariffs and inspections as means of controlling damage from this negative externality among other policy relevant results we find that 1 while it is always optimal to employ tariffs there are non trivial cases in which inspections should optimally be set to zero 2 a higher infection rate requires a higher tariff but beyond a point optimal inspections decrease in the infection rate and finally 3 taking a dynamic view and considering future effects of current introductions leads unambiguously to more stringent inspections but may give rise to higher or lower tariffs

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

on estimating the option value of preserving a wilderness area in this paper option pricing theory is used to analyse whether or not to preserve a wilderness area a numerical approach is demonstrated that can be applied to any generalized stochastic process the impact of assuming that amenity value follows a logistic process rather than geometric brownian motion is considered the calculation of critical levels for amenity value necessary to justify preserving a wilderness area such as the killarney provincial park in ontario or the headwaters forest in california is demonstrated the impact of changing the assumed growth and volatility of amenity value is also examined jel classifcation d81 q26 ce memoire utilise la theorie de la tarification d une option pour analyser si on doit preserver un espace naturel on utilise une approche numerique qui peut etre appliquee a tout processus stochastique generalise on examine l impact de possibilites que le profil de la valeur de la ressource dans la temps suive un processus logistique plutot qu un pattern geometrique de type brownien le texte montre le calcul des niveaux critiques de la valeur de la ressource qui seraient necessaires pour justifier la preservation d une espace naturel comme le parc provincial killarney en ontario ou les forets headwaters en californie l impact de postulats differents quant a la croissance et a la volatilite de la valeur de la ressource est examine

channels of interstate risk sharing united states 1963 1990 we develop a framework for quantifying the amount of risk sharing among states in the united states and construct data that allow us to decompose the cross sectional variance in gross state product into several components which we refer to as levels of smoothing we find that 39 percent of shocks to gross state product are smoothed by capital markets 13 percent are smoothed by the federal government and 23 percent are smoothed by credit markets the remaining 25 percent are not smoothed we also decompose the federal government smoothing into subcategories taxes transfers and grants to states

a note on uncertainty and the hotelling rule abstract in this paper we derive the hotelling rule of optimal natural resource depletion modified to account for uncertainty in rates of return it is shown that in the presence of risk aversion the rule implies that the expected equilibrium rate of increase of net resource price must equal the expected rate of interest if and only if there exists a zero covariance between the marginal utility of consumption and the difference between the rate of net price increase and the rate of interest the sign of this covariance is an empirical question as an example illustrates

rent seeking and resource booms abstract this paper develops a model of rent seeking in which the opportunity cost of rent seeking is foregone entrepreneurship it provides conditions under which resource booms tend to lead to an increase in rent seeking activity and those in which they induce entrepreneurship we identify an important difference between the two activities which leads resource booms to bias gains in favour of rent seeking over entrepreneurship but we also show that this bias depends on the nature of the initial equilibrium

environmental protection a theory of direct and indirect competition for political influence how is it that environmental groups can have a strong impact on environmental policy but without much lobbying this paper develops a model of direct lobbying the government and indirect persuading the public competition for political influence and finds that they are complementary however an increase in the effectiveness of public persuasion or a rise of public environmental awareness induces substitution between the two the findings establish that the empirical phenomenon of lack of political contribution from environmental groups may not be related to financial constraints but to their greater effectiveness in public persuasion and growing public environmental awareness the size of its economic stake and hence the associated lobbying effort and the efficiency of its organization in exerting political influence how then can we explain why some environmental groups have been very successful against polluting industries when the latter s economic stakes seem very high and they lobby more and their interests are more efficiently organized some might suggest that the reason for the success of the environmental movement is that environmental groups have large memberships and can provide block votes 2 however according to olson 1965 a large membership of an interest group is not necessarily an advantage and it is still uncertain whether environmental groups are able to mobilize their members to cast votes based on such affiliations this paper suggests an alternative explanation by developing a theory of direct and indirect competition between special interests for political influence rather than marshalling block votes a primary feature of our framework is that two opposing interest groups an environmentalist group and an industrialist group compete directly and indirectly for political influence in a three stage game the indirect competition takes place in the first stage in which interest groups exert effort in persuading the public to indirectly influence government policy the direct competition takes place in the second stage in which interest groups exert effort in

environmental and resource economics a canadian retrospective the paper reviews research contributions to environmental and resource economics by scholars in canada we focus mainly on work from the past 25 years but also highlight earlier pathbreaking work we begin by looking at broad trends in research both internationally and within canada we then review canadian contributions to various topics in the field canadians have played a leading role in the development of the field especially in resource economics international environmental economics and the valuation of environmental amenities

dissemination of cooking energy alternatives in india a review abstract energy requirements for cooking account for 36 of total primary energy consumption in india the rural and urban populaces depend mainly on non commercial fuels to meet their energy needs diverse urban growth patterns have led to structural changes in economy and have important ramifications on energy consumption in household sector it is observed that india follows income based ladder starting with fuelwood and ending with sophisticated fuels like liquefied petroleum gas lpg and electricity this paper discusses cooking energy dissemination in the country with an objective of understanding the underlying socioeconomic factors governing the utilization of various fuels energy carriers in cooking the diffusion of renewable energy devices is observed to be far below their estimated potential policy interventions required for better dissemination of renewable energy based devices are also discussed

taxes and subsidies for pollution intensive industries as trade policy abstract this paper constructs a model of international oligopoly with negative externalities in production in which optimal environmental policy responses to foreign emission tax and subsidy programs can be calculated it is shown that by granting subsidies for abatement efforts or for a heavily taxed polluting input domestic net welfare is improved by capturing a greater share of the world market since the subsidy programs are supposed to improve the quality of the global environment they can be justified on environmental grounds in addition we show that a pigouvion emission tax restores efficiency in natural resource allocation whereas subsidy programs are in principle used as instruments in imperfectly competitive international markets

exploration and development of u s oil and gas fields 1955 2002 we study the exploration and development of oil and gas fields in the u s over the period 1955 2002 we make four contributions to explain the economic evolution of the oil and gas industry during this period first we derive a testable model of the dynamics of competitive oil and gas field exploration and development second we show how to empirically distinguish hotelling scarcity effects from effects due to technological change third we test these hypotheses using statewide panel data of exploration and development drilling we find that the time paths of exploration development and total wells drilled are dominated by hotelling scarcity effects finally we offer an explanation for why fixed costs from exploration can make the contracting equilibrium in the mineral rights market efficient

would hotelling kill the electric car in this paper we show that the potential for endogenous technological change in alternative energy sources may alter the behaviour of resource owning firms when technological progress in an alternative energy source can occur through learning by doing resource owners face competing incentives to extract rents from the resource and to prevent expansion of the new technology we show that in such a context it is not necessarily the case that scarcity driven higher traditional energy prices over time will induce alternative energy supply as resources are exhausted rather we show that as we increase the learning potential in the substitute technology lower equilibrium energy prices prevail and there may be increased resource extraction and greenhouse gas emissions we show that the effectiveness and the incidence of emissions reduction policies may be altered by increased potential for technological change our results suggest that treating finite resource rents as endogenous consequences of both technological progress and policy changes will be important for the accurate assessment of climate change policy

on using current information to value hard rock mineral properties we reformulate the hotelling valuation principle to take into account the special production characteristics of hard rock minerals the data requirements of the revised model are still parsimonious but the resultant valuations are some 40 below those produced by the hotelling valuation principle our valuation equations are also user friendly allowing the valuer to specify price and cost expectations that need not comply with the hotelling rule empirically our model provides estimates of market value for producing mineral properties that are more accurate than those produced by the hotelling valuation principle

booming sector and de industrialisation in a small open economy this paper presents a theoretical analysis of the dutch disease the phenomenon whereby a boom in one traded goods sector squeezes porfitability in other traded goods sectors both by directly bi

globalisation growth and institutions abstract we are currently in the second wave of globalisation despite the fact that over the past two decades a number of national financial and other barriers have been removed there are still a number of national regional and global factors that are slowing down the process of financial globalisation from trickling down to all parts of the world this paper briefly discusses the process of globalisation and considers the human development index including education as a way of measuring economic growth and financial wealth in different parts of the world the paper analyses the process of financial globalisation and the way some nations have become the recipients of more foreign capital than others as a way of seeing the importance of both national and international economic and financial integration as important ingredients for sustained economic growth the process of financial integration in europe is analysed as a model for acceleration of the process of globalisation and sustained economic growth in this century the 21st century is referred to as the pacific century and hence financial integration in the asia pacific region apec could create a new impetus for the eu to increase its internal integration including its fiscal policies as a way of remaining competitive in the global economy

efficiency inducing taxation for polluting oligopolists abstract we show that there exists a time independent tax rule that guides polluting oligopolists to achieve the socially optimum production path the optimal tax is dependent on the current pollution stock and it may be negative when the pollution stock is low a surprising result is that the optimal tax rule may give firms a subsidy for an initial time interval even though under laissez faire their output always exceeds the socially optimal output this subsidy however induces firms to produce less than they would under laissez faire

unintended biological invasions does risk vary by trading partner abstract international trade is the primary conduit for unintentional and damaging species introductions but biogeographic heterogeneity and differences in historical trade exposure across trade partners suggest that not all imports are equally risky we develop an analytical model linking exotic species introductions and discoveries to trade volumes the model is estimated using a novel historical data set on global trade and species introductions by region our estimates support theoretical predictions that trade from different regions poses different risks and that the cumulative number of introductions from a region is a concave function of imports for each trade region we then calculate the marginal and cumulative invasion risk from additional trade simple volume restrictions on imports to reduce nis introductions are not advisable based on coarse cost benefit calculations

intertemporal depletion of resource sites by spatially distributed users mineral deposits and other exhaustible resources are scattered around the globe as are their users yet the theory for analyzing depletion of such resources assumes that all resource sites and all users are located in the same place when applying the theory therefore one is forced to disregard what often seems to be an important real world consideration our purpose here is to generalize harold hotelling s 1931 theory of exhaustible resources to accommodate situations in which resource sites and their users are spatially distributed our analysis has many applications it can be applied to a conventional exhaustible resource like oil alternatively it can be applied to an unconventional exhaustible resource like scarce landfill space shipments of solid waste to landfills in other states or countries have become a prominent public policy issue eduardo ley et al 2000 finally our analysis can be applied in situations where the space reflects not geographical location but characteristics of the resource e g the sulfur content hardness and so forth of coal which users find distinctive 2 only two theoretical papers in resource economics have introduced spatial considerations 3 jean jacques laffont and michel moreaux 1986 studied the extraction of resources from sites located along a line segment with all users at one end charles kolstad 1994 was the first to consider spatially distributed users in his formulation consumers are distributed uniformly along a line segment with resource sites at each end kolstad s approach although innovative requires that the set of users be parti

marketable permits market power and cheating abstract in this paper we present a model of a noncompliant firm operating in a marketable pollution permit market in the main result of the paper we show how compliance is related to the initial distribution of permits a firm with market power will cheat less the larger its endowment of permits is from a fixed stock of permits the competitive fringe however will cheat more as its endowment of permits is reduced generating an ambiguous global impact on cheating

municipal water supply and sewage treatment costs prices and distortions municipal water supply and sewage treatment utilities in ontario canada are studied in order to establish their costs of supply and evaluate their pricing practices prices charged to residential and commercial customers are found to be only one third and one sixth of the estimated marginal cost for water supply and sewage treatment respectively for example the average price to residential customers is 0 32m superscript 3 while the estimated marginal cost is 0 87 m superscript 3 the estimated cost parameters are combined with estimated residential and nonresidential demands functions in order to calculate approximate welfare losses that arise from overconsumption

systematic liquidity and the funding liquidity hypothesis abstract in order to reconcile weak evidence of supply side determinants of commonality in liquidity in previous studies we examine commonality in liquidity in china over the period 1995 2012 consistent with supply side explanations we find that market declines and market volatility increase liquidity commonality to identify the direct relationship between the supply side determinants and commonality in liquidity we provide two specific tests and show that an increase in market participants has a negative effect on liquidity commonality while the split share structure reform in 2005 2007 that results in a large increase in shares supply has a positive impact on liquidity commonality finally we find that commonality in liquidity also has a real impact on the economy

changes in wage inequality in canada an interprovincial perspective this paper uses the canadian labour force survey to understand why the level and dispersion of wages have evolved differently across provinces from 1997 to 2013 the faster increase in the level of wages and the decline in wage dispersion in newfoundland saskatchewan and alberta are the starkest interprovincial differences we find that they are accounted for by the growth in the extractive resources sectors which benefited less educated and younger workers the most increases in minimum wages since 2005 are found to be the main reason why wages at the very bottom grew more than those in the middle of the distribution

species preservation and biodiversity value a real options approach abstract we evaluate biodiversity in a real options framework when the resources in use are substitutable we examine optimal conservation decisions given that a biodiversity loss is irreversible and that future use values are uncertain while species substitutability has been shown to reduce the value of diversity we show that the flexibility associated with substitutability is a source of value marginal species value is decreasing in the number of species but rising and convex in the value of the marginal species as we show in the two species homogenous model increased volatility raises biodiversity value and a positive correlation between species values both reduces the value of the pool of species and the value of biodiversity the role played by the correlation between the value of a species and the value of other species is reminiscent of the beta of a financial asset just like an asset with a negative beta derives additional value by providing insurance against fluctuations in the market portfolio a species whose value tends to move in the opposite direction as the species in use derives additional value from its higher probability to be available for substitution if the value of the species in use diminishes

natural resources national accounting and economic depreciation abstract the current value hamiltonian in an aggregate optimal growth problem with heterogeneous capital stocks including exhaustible renewable and environmental stocks is the nnp function routine substitutions reveal that the using up of natural resource stocks is representable as easy to interpret economic depreciation magnitudes we obtain true nnp inclusive of natural resource stock diminution implications for actual national accounting practices are also discussed

resource depletion and sustainability in small open economies abstract exogenous price changes affect the amount that a small country exporting natural resource commodities must invest to sustain its consumption level the necessary amount is given by the difference between hotelling rent and the discounted sum of future terms of trade effects capital gains the latter term is found to be large relative to the former in the case of petroleum depletion in indonesia this suggests that resource rich countries will need to invest more than previously expected to sustain their consumption levels if natural resource prices continue their long term historical decline

environmental policy when market structure and plant locations are endogenous abstract a two region two firm model is developed in which firms choose the number and the regional locations of their plants both firms pollute and market structure is endogenous to environmental policy there are increasing returns at the plant level imperfect competition between the home and the foreign firm and transport costs between the two markets at critical levels of environmental policy variables small policy changes cause large discrete jumps in a region s pollution and welfare as a firm closes or opens a plant or shifts production to from a foreign branch plant the implications for optimal environmental policy differ significantly from those suggested by traditional pigouvian marginal analysis

a test of the hotelling valuation principle time series tests of the hotelling r percent rule for natural resource prices have not been strongly supportive but the tests and the data are subject to serious difficulties we propose here an alternative testing strategy based on another but less widely known implication of the hotelling model we test this implication which we call the hotelling valuation principle by regressing the market values of the reserves of a sample of u s domestic oiland gas producing companies on their estimated hotelling values we find that the estimated hotelling values account for a significant portion of the observed variations in market values and that the hotelling measures are better indicators of the market values of petroleum properties than two widely cited publicly available alternative appraisals

innovation and the dynamics of global warming global warming and the carbon cycle are a dynamic system with positive feedbacks fossil fuels are exhaustible resources these two facts mean that innovation in clean energy technology rather than mitigating global warming can lead to a permanently higher temperature path this paper explores the impact of innovation in the simplest model linking the economic theory of exhaustible resources with positive feedback dynamics in the carbon cycle

why doesn t capital flow from rich to poor countries an empirical investigation we examine the empirical role of difierent explanations for the lack of ows of capital from rich to poor countries the lucas paradox the theoretical explanations include difierences in fundamentals across countries and capital market imperfections we show that during 1970i2000 low institutional quality is the leading explanation for example improving peru s institutional quality to australia s level implies a quadrupling of foreign investment recent studies emphasize the role of institutions for achieving higher levels of income but remain silent on the speciflc mechanisms our results indicate that foreign investment might be a channel through which institutions afiect long run development

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

quota induced discarding in heterogeneous fisheries abstract individual quota iq programs are a promising and increasingly common means of regulating fisheries this paper examines how profit maximizing fishers respond to different types of iq programs in fisheries where many types of fish are harvested simultaneously this analysis shows that the most common types of individual quota programs can induce discarding and that individual quota programs that regulate the value of harvests never induce discarding since discarded fish have a high mortality rate value based individual quota programs are superior to their more conventional counterparts in that they waste fewer fish the disadvantages of value based quotas are also examined results are driven by the fact that the harvest technology examined here does not satisfy a free disposal assumption since this free disposal assumption is ubiquitous in production theory and not obviously true the framework developed herein may be useful for analyzing a broad class of problems involving joint production

environmental risks and bank liability abstract many governments have introduced or are considering introducing laws to recover from the liable parties the cleanup costs caused by pollution damages in particular the banks who finance the firms causing environmental damages may be considered liable in various court cases in the us and elsewhere banks have been found liable while they have been exempted in others we develop a model in which the insurance sector may insure the firm for the pollution risk and the bank may lend money for investment under complete information of the bank about the firm s activities the limited liability of the firm induces excessive investment and insufficient care but full liability of the bank creates the appropriate internalization of the environmental risk this rationalization of the laws on lender liability must be qualified because in general the banks suffer from agency problems adverse selection and moral hazard in their relationships with firms in the adverse selection case full liability of the bank leads to underinvestment partial liability is better but may fail to implement the optimal second best allocation in the case of moral hazard full responsibility is killing the project too often while still leading to low care too often partial responsibility may achieve the second best optimal allocation but in some cases the level of responsibility necessary to induce the proper level of care is too high for the project to be financed by the bank we conclude with a discussion of the implications of our results with regards to liability laws for environmental damages

do children matter an examination of gender differences in environmental valuation abstract this paper is concerned with the role played by children in a household on choice behaviour related to willingness to pay wtp for environmental goods improvements data from a contingent valuation cvm survey dealing with three environmental improvements are used to examine three hypotheses the first is that after controlling for income individuals with children have higher wtp than childless individuals the second hypothesis is that women with children are willing to pay more for environmental improvements than men with children particularly in the case where there is concern for environmental health risks the third is that childless men and women exhibit significant differences in wtp that arise from greater time constraints faced by women estimated wtp functions are shown to be statistically different for four groups of individuals women with children men with children women without children and men without children parents of either gender are willing to pay more than their childless counterparts valuations of mothers and fathers are statistically different for only one of the three goods being evaluated interestingly it is the fathers mean valuations that are higher this may arise from the fact that these environmental improvements lead to better recreational opportunities and as indicated earlier men are less time constrained further support for this view comes from results that show that valuations of childless men are significantly greater than those for childless women for two goods the paper concludes with some directions for future research in the area

the case for international emission trade in the absence of cooperative climate policy we evaluate the efficacy of international trade in carbon emission permits when countries are guided strictly by their national self interest to do so we construct a calibrated general equilibrium model that jointly describes the world economy and the strategic incentives that guide the design of national abatement policies countries decisions about their participation in a trading system and about their initial permit endowment are made noncooperatively so a priori it is not clear that permit trade will induce participation in international abatement agreements or that participation will result in significant environmental gains despite this we find that emission trade agreements can be effective that smaller groupings pairing developing and developed world partners often perform better than agreements with larger rosters and that general equilibrium responses play an important role in shaping these outcomes
