intrinsic bubbles the case of stock prices several puzzling aspects of the behavior of united states stock prices may be explained by the presence of a specific type of rational bubble that depends exclusively on aggregate dividends the authors call bubbles of this type intrinsic bubbles because they derive all of their variability from exogenous economic fundamentals and none from extraneous factors intrinsic bubbles provide a more plausible empirical account of deviations from present value pricing than do the traditional examples of rational bubbles their explanatory potential comes partly from their ability to generate persistent deviations that appear to be relatively stable over long periods copyright 1991 by american economic association

an initial investigation into the impact of tourism on local budgets a comparative analysis of spanish municipalities abstract the spanish federation of municipalities has particularly since 2008 been vocal about a chronic deficit situation caused by high public expenditures in tourist areas within this context new strategies to increase revenues have been proposed including the introduction of tourist taxes this paper contributes to this debate by determining if tourism activity actually has a negative impact on local finances in spain to that end a comparative analysis of budget structures between tourism intensive and non tourism intensive municipalities is undertaken using data from more than 3200 local corporations for the years 2001 2010 the determinants of expenditures revenues and deficit per capita are identified using a linear regression the results indicate a direct relationship between tourism intensity and local deficits only in the smallest and largest municipalities while a beneficial effect is actually seen in the remainder of the sample in view of this evidence we recommend revising the existing regulations to allow for municipalities below 20 000 residents to be officially recognized as tourist municipalities so that they can benefit from that status in addition the option of introducing new tourist taxes should be more restricted in scope and depend upon further evidence of possible cost inefficiency in the affected municipalities

tourism and environmental taxes with special reference to the balearic ecotax abstract during the last few decades tourism has undergone rapid growth however it seems clear that this growth is not exempt from certain costs economists attention is increasingly directed at the economic social cultural and environmental repercussions of tourism regarded as externalities focusing on the aforementioned repercussions the aim of this study is to confirm both the existence of external environmental costs and the need to internalise them with the aid of appropriate economic instruments in this respect an outline is given of the recent proposal by the government of the autonomous community of the balearic islands to introduce a tourist tax on visitors presented to public opinion in the form of an environmental tax and a critical review is made of the proposal in the light of a number of criteria regarded as relevant in the description design and implementation of these taxes

intervention analysis with cointegrated time series the case of the hawaii hotel room tax tourism taxes have become an important source of revenue for many tourist destinations in the usa among the most widely used is the hotel room tax levied by 47 states and many localities room taxes are touted by proponents as a way to shift the local tax burden to non residents while the travel industry claims the levies signi cantly harm their competitiveness previous studies of room tax impacts have relied on ex ante estimates of demand and supply elasticities in this study we analyse the ea ect onhotel revenuesof the hawaiiroom tax using timeseries interventionanalysis we specify a time series model of revenue behaviour that captures the long run cointegrating relationships among revenues and important income and relative price

prices and quantities unsustainable consumption and the global economy abstract the ecological unsustainability of current consumption patterns is now well documented one aspect of this problem which has not been sufficiently addressed is the growth of excess consumption driven by falling goods prices the index of department store prices have fallen substantially since the early 1990s in large part because global capital mobility and excess global labor supply has allowed firms to depress wages and avoid paying environmental costs consumers have responded by purchasing increasing numbers of these artificially cheap goods the example of apparel is discussed in some detail and data from other goods categories are presented these trends suggest that achieving sustainable consumption in the us is not only a technical issue but will also involve fundamental changes in the global political economy to eliminate the artificially low prices of imported goods

sustainability as a fair bequest an evaluation challenge abstract in contrast to conventional approaches the conceptualisation of sustainability as fair bequest makes it possible to consider a finite time horizon valuation is necessary to determine whether the bequest package that is passed on from one generation to the next is fair acknowledging the merits as well as the limitations of economic price theory this paper differentiates between three classes of valuables the essential the useful and the unique it is argued that a fair bequest package should contain items from each of the classes because the three classes are incommensurable fairness of the bequest cannot be expressed by a single figure like a non declining total value of the package we then discuss which methods are appropriate for describing a bequest package with respect to its fairness

tourism demand forecasting models choice of appropriate variable to represent tourists cost of living abstract price is generally regarded as a major determinant of demand tourism has two price elements the cost of travel to the destination and the cost of living for tourists in the destination previous studies where econometric forecasting models have been developed for international tourism demand usually take the consumer price index in a country to be a proxy for the cost of tourism in that country owing to lack of appropriate data this article attempts to evaluate the performance of proxy variables compared with a specific tourists cost of living variable within the context of tourism demand forecasting models

specific and general taxation of tourism activities evidence from spain abstract this article mainly discusses whether the introduction or increase of tourism taxation should be addressed through specific or general indirect taxation with this aim the paper describes the concept of tourism taxes and presents the several reasons that back their use the paper also offers some numerical exercises comparing the effects of specific and general tourism taxation in spain a developed country with a sizeable tourism industry the article suggests that both specific and general taxes on tourism would be able to yield improvements in terms of revenues and internalization of costs without hampering the economy yet in comparative terms general indirect taxes may be a more feasible equitable and neutral way to obtain tax revenues from tourism activities

status effects and environmental externalities abstract this paper examines a static competitive economy where the production of a consumption good generates pollution that adversely affects human welfare preferences are defined over consumption leisure pollution and economic status each person s status increases with her own consumption but decreases with the average consumption of society the achievement of a pareto efficient resource allocation requires a consumption tax to offset the incentive to overconsume in the pursuit of enhanced status in contrast with standard prescriptions the efficient pollution tax generally exceeds the sum of individuals marginal willingness to pay for pollution abatement these findings remain unaltered when preferences are modified to incorporate altruistic concern for others well being altruism however suggests a potential role for government intervention to achieve a desirable i e pareto efficient distribution of welfare between individuals

a micro analysis of business travel demand this study tests two hypothesis 1 that tax deductibility and the dual benefit nature of goods on the business pleasure borderline increases the demand for business travel and 2 that this dual benefit decreases price elasticity the study uses expenditure microdata and contrasts the behaviour of business travellers and pleasure travellers both groups are assumed to have indentical tastes but the expenditure behaviour of business travellers is modified by the role of the business trip as a factor of production the linear expenditure system les allocation model is applied to expenditures on individual goods at a particular tourist destination business travellers are shown to have higher expenditures than pleasure travellers for food lodging and local transportation minimum quantities estimated by the les are also higher for business travellers uncompensated price elasticities of business travellers are significantly smaller than that of pleasure travellers for local transportation clothing a

tourism s taxing times value added tax in europe and denmark abstract in recent times the business council of the world tourism organisation has been concerned at the escalation in the number of tourism taxes and the rates at which tourism is taxed there is a justifiable suspicion that governments are looking at the burgeoning tourist industry not from the rational principles of taxation but simply as a new revenue source particularly as foreign tourists are not voters in the destination the tourism industry has to cope with specific taxes such as a departure tax and general taxation such as value added tax vat this article reviews the principles by which tourism should be taxed and focuses on the different rates of vat in a european context using denmark as a case example a simulation exercise is carried out to examine the hotel sector s claim that a more efficient and equitable economic solution would result from cutting vat

is subsidising tourism firms an effective use of public funds abstract this study assesses the impact of state aid on firms in the tourism sector by implementing an accurate micro econometric evaluation of their causal effect analyses consider subsidies allocated by the main regional policy in italy the law 488 1992 during the period 1999 2003 a matching difference in difference mdid estimator is applied considering the presence of selection on observable and non observable factors effects on the tourism sector are compared with those in the manufacturing industry the impacts with respect to different types of tourism destinations where tourism firms operate are also evaluated the results show higher output and employment growth but lower labour productivity dynamics in subsidised firms relative to non subsidised ones the impacts are diverse across types of tourism destinations

a new product growth for model consumer durables this article originally appeared in management science january 1969 volume 15 number 5 pp 215 227 published by the institute of management sciences a growth model for the timing of initial purchase of new products is developed and tested empirically against data for eleven consumer durables the basic assumption of the model is that the timing of a consumer s initial purchase is related to the number of previous buyers a behavioral rationale for the model is offered in terms of innovative and imitative behavior the model yields good predictions of the sales peak and the timing of the peak when applied to historical data a long range forecast is developed for the sales of color television sets

are positional concerns stronger in some domains than in others for more than one hundred years economists have discussed the concept of positional goods that the utility conferred by many perhaps even most goods depends not only on the amount the individual consumes but also on the amount others consume e g thorstein veblen 1899 james duesenberry 1949 john k galbraith 1958 robert frank 1985 while economic interest in positional goods is increasing e g mark pingle and mike mitchell 2002 kenneth arrow et al 2004 ed hopkins and tatiana kornienko 2004 the literature remains largely theoretical rather than empirical if status concerns affect all items in the utility function equally leisure as well as goods the positional effect would operate like a lump sum tax reducing well being without changing the allocation of time or money arrow et al 2004 however if positional concerns are stronger for some things than for others then in order to understand how people can become better off in well being not simply in wealth we must investigate how interpersonal competition interacts with material gains frank 1997 evidence about what goods are more positional than others is essential for correct policy recommendations gregory besharov 2002 but little is actually known about the relative positional rankings of items in the typical consumer s utility function four hypotheses proposed in the literature are

the rate elasticity of florida tourist development aka bed taxes one aspect of taxation in florida is unique in that state policymakers have created several different tourist development taxes generally allowing local governments to adopt up to four of these ad valorem levies which can total 5 on transient rentals the rentals include but are not limited to hotel stays in this article we estimate the elasticity of this local tax base with respect to the rate for florida counties with rate changes between 1998 and 2012 results indicate several significant and large short term declines from periodic county level increases in the tax rate but no significant long term effects

sustainability of public debt public capital formation and endogenous growth in an overlapping generations setting abstract under the golden rule of public finance for public investment with a constant budget deficit gdp ratio we show that for the sustainability of government budget deficits there is a threshold of the initial public debt for a given stock of public capital and that this threshold level of public debt is increasing in the stock of public capital if the initial public debt is greater than the threshold the government can no longer sustain budget deficits while if it is smaller the government can conduct a permanent deficit policy which eventually leads to a positive public debt gdp ratio

evaluating tourism s economic effects new and old approaches abstract techniques such as multiplier analysis and input output analysis are still very commonly used to make estimates of the economic impact of changes in tourism expenditure these techniques have serious limitations and as a result alternative techniques have been developed to address the problems computable general equilibrium cge models are now extensively used especially in australia the uk the us and canada to estimate economic impacts of a wide variety of changes and policies across most sectors cge techniques have been used in the tourism context but so far not extensively economic evaluation in tourism thus fails to achieve best practice the paper presents arguments in support of cge modelling as the preferred technique in analysing the economic impacts of tourism and discusses its potential to drive future research in this area that is more relevant to real world tourism destinations

tourism demand modelling and forecasting a review of recent research abstract this paper reviews the published studies on tourism demand modelling and forecasting since 2000 one of the key findings of this review is that the methods used in analysing and forecasting the demand for tourism have been more diverse than those identified by other review articles in addition to the most popular time series and econometric models a number of new techniques have emerged in the literature however as far as the forecasting accuracy is concerned the study shows that there is no single model that consistently outperforms other models in all situations furthermore this study identifies some new research directions which include improving the forecasting accuracy through forecast combination integrating both qualitative and quantitative forecasting approaches tourism cycles and seasonality analysis events impact assessment and risk forecasting

tourism in the balearic islands a dynamic model for international demand using panel data abstract the balearic islands are one of the most important tourist destinations in the mediterranean sea the tourism sector dominates the economic activity of the islands the purpose of this study is to identify and measure the impact of the main determinants of the inbound international tourism flows the annual panel data set includes the number of arrivals from the 14 most important generating countries during the period 1991 2003 and a number of possible explanatory variables taking into account the changing structure of consumer preferences a dynamic model is estimated the estimated coefficient for the lagged dependent variable may be reflecting the importance of consumer loyalty to the destination as a determinant of tourism demand the results suggest that the demand is heavily dependent on the evolution of economic activity in each of the origin countries and on the relative cost of living of tourists in the destination this study also suggests that diversification of promotion and provision of high quality services are some recommended measures of tourism policy

the sustainability of bond financed deficits an overlapping generations approach abstract the last decade has witnessed a dramatic and fundamental shift in the expenditure and taxation policies of many western democracies a shift unprecedented in peacetime history balanced budgets have virtually disappeared from the scene in their place deficit financing has arisen as an alternative for many countries becoming a focus of both professional interest and public debate the current literature has examined this issue by assessing the likelihood that governments violate their intertemporal budget constraint this paper takes a different tack we incorporate permanent fiscal deficits into an overlapping generations model and evaluate the implications we already know that if the steady state interest rate is less than the growth rate then permanent deficits are indeed sustainable however this is a necessary but not a sufficient condition in addition these deficits and the current stock of debt must also not be too big we calibrate the model to u s data with plausible parameters of taste and technology derive the theoretical limit to the maximal sustainable deficit implied by this model and discuss the relevance of our findings for current policy issues

commercial real estate prices and stock market returns an international analysis the movement toward globalization of institutional investments requires an understanding of the historical relationship between international commercial real estate price changes and stock returns previous studies have focused on the time series of stock and real estate returns using data from a single country by necessity these studies examined returns and price changes over short intervals creating a bias when property values are smoothed from year to year this study examines the relation between stock returns and changes in property values and rents based on data from 17 countries although we find no relation between real estate values and rents and stock returns in the united states we find significant relations in a number of other countries when the data are pooled the relation between stock returns and both value changes and changes in rental rates is very strong

incorporating resilience in the assessment of inclusive wealth an example from south east australia this paper explores the consequences of changes in a system s resilience on the sustainability of resource allocation decisions as measured by inclusive wealth iw arrow et al in environ resour econ 26 647 685 2003 we incorporate an estimate of resilience in iw by taking account of known or suspected thresholds that can lead to irreversible or practically irreversible changes in the productivity and value of assets and hence social welfare these thresholds allow us to identify policies or projects that may be leading to an increased risk of decline in capital stocks the wealth of the region such risks are not reflected through usual measures of current system performance e g agricultural production we use the goulburn broken catchment in south eastern australia as a case study to explore the significance and practicality of including resilience in inclusive wealth estimates

the ambiguous effects of taxing foreign buyers abstract i model the effects of a discriminatory tax in the context of monopoly the monopolist serves two types of customers locals and foreigners while the firm may or may not price discriminate the government taxes foreign customers only i show that this tax has ambiguous effects on price output and welfare under uniform pricing moreover it may reduce local welfare even if the price falls i also show that the tax reduces output and local welfare under third degree price discrimination

on the limitations of government borrowing a framework for empiricaltesting this paper seeks to distinguish empirically between two views on the limitations of government borrowing according to one view nothing precludes the government from running a permanent budget deficit paying interest due on the growing debt load simply by issuing new debt an alternative perspective holds that creditors would be unwilling to purchase government debt unless the government made a credible commitment to balance its budget in present value terms we show that distinguishing between these possibilities is mathematically equivalent to testing whether a continuing currency inflation might be fueled by speculation alone or is instead driven solely by economic fundamentals empirical tests which have been developed for this economic question lead us to conclude that postwar u s deficits are largely consistent with the proposition that the government budget must be balanced in present value terms this abstract was borrowed from another version of this item

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

the siable law model of stock returns this study investigates the tail shapes of empirical distributions of returns on an extensive group of common stocks the tails of the return distributions are found to be thinner than those of infinite variance stable distributions therefore although homogeneity is evident in general economic and statistical inferences drawn from stable law parameters estimated from samples of stock returns may be misleading this is in spite of the apparent overall similarity in shape between empirical and stable distributions

net national product as an indicator of sustainability net national product nnp can potentially serve several objectives among others to measure value added and to be an indicator of welfare in the aftermath of the world commission on environment and development however it also seems important to investigate whether the concept of nnp can serve as an indicator of sustainability my point of departure following hicks 1946 ch 14 is therefore to require that nnp should measure what can be consumed in the present period without reducing future consumption possibilities and in line with this to argue that the nnp should equal the maximum per capita consumption level that can be sustained if sufficiently many facilitating assumptions are made then a concept of nnp that serves as an exact indicator of sustainability can easily be constructed for instance for a closed economy with a constant population a stationary technology and with only one capital good it follows that the present does not reduce future consumption possibilities if and only if it does not decrease the stock of the single capital good hence under the assumption that the one capital good k is identical to the one consumption good x nnp defined as y x k measures the maximal sustainable consumption at time t because then x y is equivalent to k the purpose of this note is to establish that with multiple capital goods it is not in general possible to construct an exact indicator of sustainability on the

capital theory and the measurement of sustainable development an indicator of weak sustainability the measurement of sustainable development is not without considerable difficulties yet this should not detract from the positive advances that can be made in this direction in this paper we present one form that a weak sustainability indicator can take derived from a simple but intuitive savings rule it incorporates the idea that the level of overall capital stock should be non decreasing although subject to qualification at this stage some interesting results emerge from the application of the rule to 18 countries

cointegration how short is the long run abstract when testing for cointegration and faced with short sample periods it is common for researchers to turn to more frequently sampled observations that is to move from annual to quarterly or monthly data in order to increase the number of observations we argue that such a gain in the degrees of freedom is more apparent than real essentially cointegration is a long run concept and hence requires long spans of data to give tests for cointegration much power rather than merely large numbers of observations using monte carlo simulations we demonstrate this for four popular tests for cointegration

capital market integration and fiscal sustainability abstract by constructing a two country endogenous growth model with a debt financing government this paper studies the relationship between the sustainability of public finance and increases in inter regional factor mobility to this end it identifies the minimum tax rate that ensures fiscal sustainability against the backdrop of capital tax competition and studies whether competition for mobile capital lowers or improves fiscal sustainability the main findings are as follows i when countries are symmetric increasing capital flows promotes economic growth through the expansion of romer type knowledge spillovers resulting in increased fiscal sustainability in all countries and ii when a marked difference exists between countries tax competition caused by capital movements might lower fiscal sustainability in a country with abundant capital and large outstanding debt

land and stock prices in japan in late 1991 the total land value in japan was estimated at nearly 20 trillion this was more than 20 percent of the world s wealth or to put it in some other contexts about double the world s equity markets or half again as large as the world s bond markets japanese land was then valued at about five times that of the united states the land under the emperor s palace which is about three quarters of a square mile was estimated to be worth about the same as all the land in california or in canada real estate assets of japanese corporations grew by 2 8 trillion from 1986 to 1988 an increase in valuation roughly equal to the size of the japanese gross national product an equally dramatic rise in stock prices accompanied the rise in land prices at its peak in december 1989 the japanese stock market had a value of about 4 trillion which was about 44 percent of the world s equity market capitalization to put that figure in perspective the value of the equity on all the stock exchanges in the united states in august 1992 was less than 5 trillion but then from its peak in december 1989 to august 1992 the japanese stock market fell by over 60 percent various indices of speculative land values fell a similar amount meanwhile other land prices industrial commercial residential as measured by various indices fell 15 20 percent this paper discusses the rise of japanese stock and land prices in the past four decades and their dramatic decline in the early 1990s to what extent can

questioning demand a study of regretted purchases in great britain abstract this paper presents findings from a nationally representative household survey on the tendency to regret purchases across 20 product groups the survey reveals that the vast majority of adults in great britain 82 have regretted a purchase in the past post purchase regret is shown to be particularly prevalent for clothing footwear and takeaway food the tendency to regret purchases appears to reduce with age and to be more common amongst white collar rather than blue collar workers combining survey results with average price estimates gives an estimated aggregate annual expenditure on regretted purchases of 5 25bn equivalent to 2 10 of annual consumer spending on goods in great britain these findings are interesting because they suggest that there is a degree of self assessed over consumption that if reduced could help to reduce pressures on the environment

public sector capital and the productivity puzzle a number of studies have suggested a quantitatively important relationship between public sector capital accumulation and private sector productivity with the most compelling evidence derived from analyses of state level data estimates herein of production functions that use standard techniques to control for unobserved state specific characteristics however reveal essentially no role for public sector capital in affecting private sector productivity only estimates of state production functions that do not include such controls find substantial productivity impacts this result reconciles existing econometric estimates with the findings of hulten and schwab based on growth accounting techniques as such techniques effectively control for state specific effects region level estimates are essentially identical to those from state data suggesting no quantitatively important spillover effects across states copyright 1994 by mit press

were japanese stock prices too high abstract this paper asks whether market fundamentals can explain the recent run up and decline of japanese equity values and price earnings ratios accounting differences explain about half of the long run disparity between u s and japanese p e s for example if japanese firms used u s accounting rules the japanese p e ratio would have been 32 6 not 53 7 in 1989 accounting differences cannot however explain the doubling of this ratio in 1986 nor its decline in 1990 similarly we are unable to isolate changes in required stock returns or growth expectations that are large enough to explain recent japanese stock price movements

the economic analysis of biodiversity an assessment biodiversity is complex difficult to define difficult to measure and often involves international and intergenerational considerations biodiversity loss presents significant economic challenges a great deal of economics is required to understand the issues but a simple and important observation is that most species and ecosystems are not traded in markets so prices are often absent and biodiversity is under provided despite the formidable obstacles to high quality economic analysis economics has plenty to offer to biodiversity policy first economic valuation techniques can be employed to roughly estimate the value of the benefits provided by biodiversity and ecosystems second assessing the optimum amount of biodiversity involves recognizing that the conversion of natural capital into manufactured and human capital has so far generated vast amounts of wealth while there may have been too much biodiversity in the past economic analysis suggests that this is a difficult position to hold now third econometric techniques and carefully designed policy studies can assist in determining what policies are most suited to different contexts to cost effectively reduce biodiversity loss fourth political economy is helpful because international coordination is often required ecosystems do not respect national borders and many biodiverse ecosystems are in poorer countries this paper synthesizes the issues and proposes a research agenda which includes improving the measurement and accounting of natural capital improving valuation techniques and theory to provide greater guidance as to the optimum biodiversity and developing our understanding of the merits of different alternatives for government intervention to reduce biodiversity loss

conservation and human welfare economic analysis of ecosystem services the importance of the links between well functioning ecosystems and human well being are clearly evident in our age of rapidly changing environmental and socio economic conditions and yet the role ecosystems play in supporting and sustaining human welfare has been only a marginal area of study to date in the field of economics dasgupta 2010 but this is starting to change millennium ecosystem assessment 2005 and the burgeoning literature on ecosystem services that has followed largely instigated by work in ecology has begun to percolate into economics the number of articles by economists on various aspects of ecosystem services including the benefits of conserving ecosystems and biodiversity tradeoffs among services payments for ecosystem services pes and other incentive mechanisms has risen dramatically in the past several years still the economics literature on ecosystems and biodiversity is nowhere near as prominent as the economics literature on climate change economists have played a central role in defining the key elements of the debate on climate change following publication of the stern review stern 2007 and the ensuing debates e g nordhaus 2007 sterner and persson 2008 weitzman 2007 economists have yet to play such a central role in ecosystem services and biodiversity ecosystems provide a wide range of benefits from the water and climate regulation roles of forests the waste assimilation and storm regulation capacities of wetlands to the cultural and aesthetic benefits derived from savannas ecosystems processes and raw materials are

20th anniversary of eaere the european association of environmental and resource economists environmental and resource economics occupies a curious place in contemporary economics i know of no economist who does not regard nature to be a vital capital asset nor do i know any economist who does not regard humanity s dealings with nature to involve inter temporal externalities and yet most economists appear to be convinced that technological advances and the accumulation of reproducible capital and growth in human capital can overcome diminutions in natural capital otherwise it is hard to explain why twentieth century economics has been so detached from the environmental sciences judging by the profession s writings we economists see nature when we see it at all as a backdrop from which resources and services can be drawn in isolation macroeconomic forecasts routinely exclude natural capital and accounting for nature if it comes into the calculus at all is an afterthought to the real business of doing economics when asked economists acknowledge nature s existence but many deny she is worth much at the margin i have heard professional colleagues remark at seminars that the services nature provides amount at best to 2 3 of an economy s output which is the share of agriculture in the gross domestic product of the united states why they ask should one incorporate a capital asset in macro economic models of growth and distribution when it is of negligible importance typically growth models assume that nature is a fixed indestructible factor of production 1 the problem with the assumption is that it is wrong nature consists of degradable resources agricultural land forests watersheds fisheries fresh water sources wetlands the atmosphere more generally ecosystems are assets that are self regenerative but suffer from depletion or deterioration when they are over used 2 the innumerable processes that characterize nature run at different speeds and operate at different spatial scales which give rise to positive feedback loops that unless countered can mean catastrophes for people ranging from village communities to populations covering entire biomes moreover the environmental sciences tell us that the elasticity of substitution between reproducible capital and

when can carbon abatement policies increase welfare the fundamental role of distorted factor markets abstract this paper employs analytical and numerical models to assess the welfare effects of a revenue neutral carbon tax and nonauctioned carbon emissions permits taking into account preexisting tax distortions in factor markets the presence of preexisting taxes significantly raises the general equilibrium costs of both policies this cost increase is much greater under emissions permits since this policy does not generate revenues to reduce distortionary taxes under our central estimates emissions permits cannot increase welfare unless environmental damages exceed about 18 per ton of carbon in contrast an appropriately scaled carbon tax is welfare improving so long as environmental damages are positive

evaluating projects and assessing sustainable development in imperfect economies we are interested in three related questions 1 how should accounting prices be estimated 2 how should we evaluate policy change in an imperfect economy 3 how can we check whether intergenerational well being will be sustained along a projected economic programme we do not presume that the economy is convex nor do we assume that the government optimizes on behalf of its citizens we show that the same set of accounting prices should be used both for policy evaluation and for assessing whether or not intergenerational welfare along a given economic path will be sustained we also show that a comprehensive measure of wealth computed in terms of the accounting prices can be used as an index for problems 2 and 3 above the remainder of the paper is concerned with rules for estimating the accounting prices of several specific environmental natural resources transacted in a few well known economic institutions

efficient regulation with little information reality in the limit we present a regulatory scheme that converges to ramsey pricing and productive efficiency even if regulators have little information about technology or demand the model has firms selecting prices subject to the regulator s requirement that the firm earn a fair return on capital at today s capital stock and output levels regulators then review later performance and are more likely to request new rate hearings as the firm s return deviates more from the fair return as long as regulators do not review negative returns too fast relative to positive returns these conditions are sufficient for convergence to ramsey prices and productive efficiency public utility regulators generally set prices not rates of return per se these prices however often are meant to achieve approximately some target rate of return but when projecting how prices will affect rates of return regulators are often at the mercy of the firms for economic projections about the effects of various price vectors e g across customer classes upon profits so if realized rates of return deviate from targets regulators may call new rate hearings and they may expedite these hearings if the deviations are large 2 by formalizing these real world observations some rather surprising efficiency results appear suppose that regulators have no knowledge of demands and technologies but can observe past realizations of prices and quantities if the review probabilities are as noted above and satisfy an asymmetry condition then this regulatory process may converge not only to productive efficiency overcoming averch johnson over capitalization effects but to ramsey prices these conclusions are derived from unifying and extending work by bawa and sibley 1980 and vogelsang and finsinger 1979

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

ownership risk investment and the use of natural resources the effect of insecure ownership on ordinary investment and natural resource use is examined insecure ownership is postulated to depend on the type of government regime in power and the prevalence of political violence or instability the political determinants of economy wide investment are estimated from cross country data and the results are used to form an index of ownership security when introduced into empirical models of natural resource use this index has a significant and quantitatively important effect on the use of forests and petroleum contrary to conventional wisdom ownership risk slows resource use in some circumstances

credible regulatory threats abstract as competition emerges in parts of utility industries and utility regulation policy is reviewed it is useful to examine alternative forms of regulation that may be implemented when hit and run entry is believed to be a non credible threat potential entry may not constrain incumbent firms pricing and production decisions this paper proposes that the credible threat of intervention by a regulator may impact upon incumbent firms decisions empirical evidence from the english and welsh electricity pool market is investigated to discover whether the threat of regulator intervention may have influenced the pricing strategies of the dominant firms in this market

the short term price effect of a tourist tax through a dynamic demand model the case of the balearic islands abstract tourist taxes have become an important source of revenue for many tourist destinations taxes on accommodation are upheld by their proponents as a way of shifting the local tax burden on to non residents while the travel industry claims that these levies do significant damage to their level of competitiveness the objective of this paper is to identify the market s sensitivity to price changes in travel related services or groups of services assuming that one of the main factors that influences travel decisions is the information on the destination that consumers receive in order to include this effect the study applies a combination of a diffusion model and a traditional economic utility theory model to tourists visiting the balearic islands spain from the united kingdom germany france and the netherlands

spatial aggregation and the value of natural capital abstract location matters for the value of capital assets the value of changes in natural capital wealth can depend on whether natural capital asset prices are measured locally and then aggregated or whether average values are applied over aggregate representative areas spatial heterogeneity of resource characteristics and institutions impact approximations of the intertemporal welfare function and accounting price function because when spatial aggregation precedes valuation it implies greater arbitrage opportunities leading to more inelastic shadow accounting price functions than when valuation is done locally and then aggregated aggregation of observed values across varying resource and institutional characteristics can lead to omitted variables bias we illustrate these results in the context of groundwater in the kansas high plains aquifer and demonstrate that the accounting price function is less elastic when the accounting price is measured locally failure to measure locally and then aggregate could lead to undervaluing scarce resources and overvaluing plentiful ones which biases wealth accounts in favor of passing the non declining wealth sustainability test

exhaustibility and risk as asset class dimensions a social investor approach to capital resource economies this paper develops a framework in which asset class dimensions are extended to include both risk and exhaustibility for explaining the evolution of shadow prices of marginal units of exhaustible natural resources in capital resource economies it is shown that the pricing kernel function required for socially valuing marginal units of exhaustible resource hereafter called the exhaustion stochastic discount factor combines a factor that discounts for risk and another factor that discounts for resource exhaustion over time the social rate of return on the marginal unit of resource stock adds to the risk premium an exhaustion premium that accounts for the resource depletion over time in this setting the principle of no arbitrage holds by extending asset class dimensions to include not only a risk dimension but also an exhaustibility dimension

the economics of the climate i review the economic characteristics of the climate problem focusing on the choice of discount rates in the presence of a stock externality risk and uncertainty ambiguity and the role of integrated assessment models iams in analyzing policy choices i suggest that iams can play a role in providing qualitative understanding of how complex systems behave but are not accurate enough to provide quantitative insights arguments in favor of action on climate issues have to be based on aversion to risk and ambiguity and the need to avoid a small but positive risk of a disastrous outcome

are we consuming too much this paper articulates and applies frameworks for examining whether consumption is excessive we consider two criteria for the possible excessiveness or insufficiency of current consumption one is an intertemporal utility maximization criterion actual current consumption is deemed excessive if it is higher than the level of current consumption on the consumption path that maximizes the present discounted value of utility the other is a sustainability criterion which requires that current consumption be consistent with non declining living standards over time we extend previous theoretical approaches by offering a formula for the sustainability criterion that accounts for population growth and technological change in applying this formula we find that some poor regions of the world are failing to meet the sustainability criterion in these regions genuine wealth per capita is falling as investments in human and manufactured capital are not sufficient to offset the depletion of natural capital

estimating the impact of anti dumping and anti cartel actions using intervention analysis intervention analysis is proposed as a method for estimating the effects of anti dumping actions in the presence of a domestic cartel data requirements and modelling effort compare favourably with traditional structural model approaches the method is applied to an antidumping action brought to the european commission and in which the european producers of the product were fined after an anti cartel action by the commission covering an overlapping period intervention analysis is applied to distinguish the effects of the anti dumping action from those of changes in cartel behaviour it has been argued that in the post uruguay round world anti dumping ad actions as with other contingent protection measures may become an instrument of choice in place of tariffs to restrict international trade messerlin and reed 1995 some reasons for this may be found in the political economy literature tharakan 1991 1995 where it is argued that such measures which are typically non transparent quasijudicial gatt legal and capable of being targeted at the level of an individual supplier may prove very tempting to both policymakers and those lobbying for protection if economists are to have an effective input to the debate on such measures then it is essential to be able to estimate the consequences of such protection preferably in a way that provides reasonable estimates without the need of onerous data or logistical requirements in this paper we propose a tractable time series based method that requires minimal data the unit value and volume of imports data series we illustrate the technique by reporting estimates of the costs to the united kingdom of the price undertaking that resulted from the successful ad action brought to the european commission in 1982 and directed at four japanese suppliers of polypropylene pp film the illustration is also of interest because a subset of those european pp producers bringing the ad action were the subject of an anti trust ruling that resulted in fines for collusive behaviour messerlin 1990 the anti cartel judgement covered the period during which the industry lodged the complaint of dumping and secured minimum price undertakings from thejapanese producers anti dumping actions in the european union may be resolved in favour of the complainants by the imposition of ad duties adds or more commonly by the foreign suppliers targeted in the actions voluntarily giving an under

irreversibility and uncertainty cause an intergenerational equity efficiency trade off abstract two important policy goals in intergenerational problems are pareto efficiency and sustainability i e intergenerational equity we demonstrate that the pursuit of these goals is subject to an intergenerational equity efficiency trade off our analysis highlights two salient characteristics of intergenerational problems and policy i temporal irreversibility i e the inability to revise one s past actions and ii uncertainty of future consequences of present actions in human environment systems we employ a two non overlapping generations model that combines an intragenerational production decision on the use of circulating capital and a non renewable resource with a negative intergenerational externality as an unforeseen contingency if initially unknown problems become apparent and policy is enacted after irreversible actions were taken policy making faces a fundamental trade off between ex post pareto efficiency and sustainability that is one can achieve either one of these two goals but not both

regulating environmental threats environmental consequences of natural resource exploitation often entail threats of future occurrences of detrimental abrupt events rather than or in addition to inflicting a damage gradually the possibility of abrupt occurrence of climate change related calamities is a case in mind the uncertainty associated with the realization of these threats and their public bad nature complicate the design of optimal economic response we derive a pigouvian hazard tax schedule that implements the socially optimal outcome the tax is based on the expected cost of the hazard generating activities and serves to reduce hazardous emissions well in advance of the catastrophic occurrence a numerical example illustrates possible effects of the proposed regulation scheme implications for climate policy are discussed

the pricing of japanese equity warrants discrepancies between the black scholes value of japanese equity warrants and their observed prices are explained in part by the stochastic volatility of changes in prices of the underlying stocks we fit garch and egarch models to the stochastic volatility and briefly compare their performance to the cev model a hopscotch algorithm is used to value the warrants in the presence of the stochastic stock price volatility the stochastic volatility hopscotch warrant values still differ substantially from corresponding prices in contrast away from the money short term nikkei 225 options valued with the same stochastic volatility models are close to observed prices a regression model is used to fit the differences between warrant values and prices as a function of proxies for market impediments

status effects and negative utility growth this paper explains the observed stagnation of happiness measures through a growth model in which agents care about conspicuous consumption normal goods confer direct utility while status goods confer utility only at the expense of others firms can improve the quality of both goods through r d the nash equilibrium of the consumer game results in the share of expenditure on status goods increasing with the number of times the status good has been improved as the economy grows resources for innovation are transferred entirely to status good r d the resulting long run rate of utility growth is negative

inclusive wealth with a changing but aging population we consider the effect of population age distribution in inclusive wealth accounting numerical results demonstrate that the wealth of nations with an aging demographic structure as well as those with a rapidly increasing working age generation may have been overestimated

an applied general equilibrium analysis of the economic effects of tourism in a quite small quite open economy a computable general equilibrium model is used to project the effects of tourism on the industrial and regional structures of the australian economy the most striking conclusion is that queensland usually thought to be the most tourism oriented of the australian states would be a net loser from an economy wide expansion of tourism as well as having a relatively large share of its gsp accounted for by tourist oriented activities queensland is also relatively heavily dependent on agriculture and mining traditional export sectors which are crowded out by the expansion of international tourism

the assessment introducing competition into regulated industries the introduction of competition into utilities is currently being pursued in the many countries including the uk competition can take various forms such as competition for outputs inputs franchises and outright takeovers attention is currently focused on output competition whereby customers are being given a choice of final supplier in many industries we consider the implications of the introduction of such competition including the effects on industrial structure and contracts cross subsidies and distributional concerns and uncertainty and stranded contracts we also analyze the transitional problems encountered as competition is introduced and suggest that the uk regulators and government have in some key respects failed to define a clear and consistent policy

dynamic analysis of an endogenous growth model with public capital this paper develops an endogenous growth model with productive public capital along with private capital in a spirit similar to that of r j barro 1990 since the authors model includes two stock variables it has transitional dynamics unlike most of the previous studies on endogenous growth including barro s where concerns are restricted to the steady state analysis first they show that the transitional path is unique and stable second the character of the transitional path is explored third the authors show that the optimal tax rate is smaller than the rate that maximizes the national growth rate with a log linear utility function copyright 1993 by the editors of the scandinavian journal of economics

an empirical study of outbound tourism demand in the uk a general to specific methodology is used to construct uk demand for outbound tourism models to twelve destinations a tourism destination preference index is introduced to take into account social cultural and psychological influences on tourists decisions concerning their overseas holiday destinations the tests support the existence of a cointegration relationship for each of 11 uk overseas holiday destinations the corresponding error correction models are estimated the empirical results show that the long run income elasticities for all destinations range from 1 70 to 3 90 with an average of 2 367 the lowest and highest short run income elasticities are 1 05 and 3 78 respectively with an average of 2 216 the estimates of the income elasticities imply that overseas holidays are highly income elastic while the own price elasticities suggest that the demand for uk outbound tourism is relatively own price inelastic in terms of the significance of substitution prices in the regression equations ir
