from shadow to green linking environmental fiscal reforms and the informal economy in the past few decades many papers have analysed in some depth different environmental tax reforms and the double dividend hypothesis i e the possibility of improving not only the environment but also the economy through the reduction of distortions in the tax system recently more stress has been placed on testing empirically what effects a reduction in labour taxes may have on unemployment when accompanied by a carbon or other environmental tax however such studies have not modelled the effects of the presence of a shadow economy even though informal markets account for a significant and growing part of gdp in many developed economies this paper analyses this link using an applied general equilibrium model for the case of spain which has one of the highest unemployment rates in the world and one of the biggest informal economies of any wealthy country we conclude that our analysis strengthens the case for an environmental tax reform in spain if revenues from a co2 tax are recycled via a labour tax reduction

the demand for energy cross country evidence using the florida model abstract income and own price elasticities of demand for energy for 51 countries in 1980 are presented based on pooled estimates from an 11 good demand system estimated with the florida model results indicate income elasticities of demand for energy are significantly larger than unitary for all countries and own price elasticities of demand for energy range between 0 8 and 1 0

dairy tariff quota liberalization contrasting bilateral and most favored nation reform options we develop a highly disaggregated tariff line source differentiated partial equilibrium model of u s specialty cheese imports to investigate alternative reform options for tariffrate quotas a mixed complementarity framework is used to represent bilateral and multilateral tariff quota administration methods within the u s dairy industry the impact of liberalizing u s specialty cheese imports via bilateral and multilateral tariffrate quota expansions out of quota tariff cuts and simultaneous liberalization scenarios is evaluated we find that the path of liberalization is quite different depending on the reform approach undertaken the results have important policy implications in the agricultural negotiations

the demand for energy evidence from a cross country demand system abstract some new evidence on the income own price elasticities of demand for energy consumption by consumers is presented estimates are derived from a complete system of cross country demand equations with energy being one of the commodities considered

estimating the distortionary effects of ethnic quotas in singapore using housing transactions abstract desegregation is a key policy issue in many countries i investigate a residential desegregation program in singapore the ethnic housing quotas i show that choice restrictions imposed on apartment blocks above the quota limits constrained could have distortionary effects causing price and quantity differences for constrained versus unconstrained blocks i test these predictions by hand matching more than 500 000 names in the phonebook to ethnicities to calculate ethnic proportions at the apartment block level i can then investigate differences for constrained and unconstrained blocks close to the quota limits and test for sorting around the limits i find that price differences are between 3 and 5 quantity effects are economically significant translating to longer time on market durations selection cannot fully explain these results my results point to challenges in achieving desegregation using quantity restrictions

micro foundations of external economies the first purpose of this paper is to specify certain microeconomic determinants of external economies and then analyze the consequences of these economies for production and welfare in a simple general equilibrium model the second purpose is to explore the circumstances under which the implied industry production functions are consistent with the ad hoc specifications used in trade theory and growth theory the motivation for the latter exercise is that despite progress in general equilibrium analysis of internal economies these industry production functions allow the author to capture the very powerful analytical advantages of competitive general equilibrium and duality theory

can a carbon permit system reduce spanish unemployment this paper analyses the impact of carbon policy on unemployment in spain and whether recycling the public revenues earned from permit auctions can alleviate this problem while spain s deviation from the european union s intermediate emission goals is more serious than most other member countries unemployment in spain is also well above average for the european union we use a computable general equilibrium model that includes unemployment in the markets for unskilled and skilled labour we find that introducing carbon permits does not aggravate spanish unemployment in fact if supplied with revenue recycling schemes unemployment rates may actually fall contrary to other european studies we find that the best option is to reduce payroll taxes on relatively skilled types of labour this reform is successful in both increasing labour demand and dampening the supply response to rising wages however while all of the recycling schemes generate dividends in terms of aggregate welfare none entirely offsets the abatement costs

growth and employment the scope of a european initiative this paper is an abridged version of a policy initiative paper prepared with a dozen colleagues in louvain la neuve and paris we propose a set of policies to cope with europe s persistent unemployment including two medium term programs a drastic reduction of the indirect cost of unskilled labour and an ambitious stimulation of targeted investments the bottom line is that policies addressing meaninfully europe s unemployment problem must be pursued on a bolder scale than currently contemplated

the optimality of tariff quotas under uncertainty abstract a tariff quota is a schedule of tariffs in which the tariff rate steps upward as imports exceed some critical quantity or value this has desirable properties in the face of uncertainty about domestic demand and supply and about foreign supply we show that a specific ad valorem tariff quota is the policy maximizing domestic expected surplus subject to constraints on average imports import expenditure and on the average amount by which imports import expenditure exceed some critical value

environmental taxation and unemployment some evidence on the double dividend hypothesis in europe abstract the employment double dividend hypothesis suggests that an appropriately designed fiscal reform in which emission charges are used to subsidize employers social security contributions may realize at least two relevant policy goals a better quality of the environment and at the same time an increase in employment levels this paper uses a newly developed econometric general equilibrium model for the european union as well as for each member country and presents simulation results up to the year 2010 of the effects of a european carbon tax the revenues from which are recycled to reduce employers social security contributions the results show that recycling carbon tax revenues may provide an employment double dividend only in the short run

tax reform and the dutch labor market an applied general equilibrium approach abstract this paper develops an applied general equilibrium model to explore various tax cuts aimed at combating unemployment and raising labor supply the model calibrates modern labor market theories on wage setting job matching labor supply and labor demand on dutch data it represents the core of a larger applied general equilibrium model for the netherlands called mimic simulations reveal that targeting in work benefits at the low skilled is the most effective way to cut economy wide unemployment however targeting is likely to damage the quality and quantity of labor supply tax cuts in the higher tax brackets boost the quantity and quality of formal labor supply but are less effective in reducing unemployment and in raising unskilled employment and female labor supply

progressive taxes and the labour market is the trade off between equality and efficiency inevitable does an income tax harm economic efficiency more the more progressive it is public economics provides a strong case for a definite yes but at least three forces may pull in the other direction first low wage workers may on average have more elastic labour supply schedules than high wage workers in which case progressive taxes contribute to a more efficient allocation of the total tax burden second in non competitive labour markets progressive taxes may encourage wage moderation and hence reduce the equilibrium level of unemployment and third if wage setters have egalitarian objectives progressive taxes may reduce the need for redistribution in pre tax wages and hence increase the demand for low skilled workers this paper surveys the theoretical as well as the empirical literature about labour supply taxes and wage setting we conclude that in a second best world the trade off between equality and efficiency is not always inevitable copyright 2002 by blackwell publishers ltd

optimal allocation of quotas abstract consider a government which fixed the supply of a good e g by an import quota suppose the market for the good can be partitioned e g sales in different years or in different areas of the country can be considered sales in different markets we show that maximization of consumer surplus in the domestic economy may require segmentation of the domestic market into two but no more parts

income and price elasticities of demand at low levels of real income abstract for levels of real per capita income starting at 3 of the u s per capita income in 1975 income and price elasticities of demand are tabulated the prominent role of food consumption for low income households is emphasized

recycling energy taxes impacts on a disaggregated labour market abstract this paper analyses the impacts of energy taxes whose revenue is recycled to reduce gross wages and increase employment the main novel feature of this paper is the attempt to assess the effectiveness of this fiscal reform by using a labour market model in which both skilled and unskilled workers are used in the production process this segmentation enables us to compare a policy which aims at reducing unskilled workers wages as in the original delors white book with a policy in which the environmental fiscal revenue is used to reduce the gross wage of all workers moreover two policy scenarios will be considered a non co operative one in which each country determines the optimal domestic energy tax to achieve a given employment target and a co operative one in which the energy taxes are harmonised to equalise marginal abatement costs in the eu and in which the employment target is set for the eu our results show that i an employment double dividend can be achieved in the short run only even if a trade off between environment and employment always exists ii the effect on employment is larger when the fiscal revenue is recycled into all workers gross wages rather than into unskilled workers only iii a co operative policy leads to even larger benefits in terms of employment provided that an adequate redistribution of fiscal revenues is adopted by eu countries

carbon pricing and energy efficiency improvement why to miss the interaction for developing economies an illustrative cge based application to the pakistan case abstract carbon energy taxes and energy efficiency improvement are studied well in the recent years for their potential adverse impacts on economy especially for lost production and international competitiveness and rebound effects however little attention has been paid to investigate them jointly which can not only prevent fall of energy services cost and thereby rebound effect but reduce the associated macroeconomic costs this study thus employs a 20 sector cge model to explore separately the impacts of carbon tax and its coordinated implementation with energy efficiency improvement on the pakistan economy the country underwent enormous pressure of energy security issues as well as climate change fallouts in the last couple of years and can be regarded as a suitable candidate for energy environmental conservation policies to be considered at a broader context with more concrete efforts the simulation results show that the impact of carbon tax on gdp is negative but resulting reductions in pollutant emissions are relatively high moreover the gdp is expected to grow comparatively positive when analyzed with improvements in energy efficiency with even higher decline in energy consumption demand and so emissions this simultaneous economic and environmental improvement would thus have positive implications regarding sustainable development of the country

the asymmetric effects of reversible tariff changes under the united states gsp in a partial equilibrium textbook model of competitive international trade the volume and net value of imports always vary inversely with the tariff rate this result depends on assumptions that the tariff changes are substantial exogenous permanent and applied on a most favorednation mfn basis empirical applications of this theory however encounter different conditions generalequilibrium effects such as changes in prices exchange rates and income tend to be offsetting imperfect competition can make the incidence of the tariff indeterminate many tariff changes are small endogenous temporary and or discriminatory to illustrate how these differences in tariffs can alter their observed relation to imports we offer the following examples a tokyo round cuts in u s tariffs were staged generally over eight years and averaged only 0 3 percent per annum 6 as compared to 6 4 percent average annual changes in american import prices over the same 1980 87 period 18 if search and recontracting costs caused buyers to ignore relatively small price variations then many observed tariff changes would produce negligible effects b governments tend to lower tariffs when imports are low enough to obviate political problems and they raise them as a response to import surges observers who ignore this endogeneity might conclude that imports are positively related to tariff rates c while many tariff concessions are bound under the gatt some duties are temporarily altered to provide import relief for domestic producers or preferential access for certain trade partners importers may not respond if the temporary benefits of doing so are exceeded by the costs of finding substitutes d the importers response to a tariff change will also differ between cases where some or all imports of a given product are affected a discriminatory tariff change might shift the shares of suppliers while leaving total imports virtually unaltered empirical studies seldom test the relation between imports and tariffs directly time series estimates of import demand equations usually subsume the tariff in a gross price variable

an empirical model of mark ups in a quality differentiated export market abstract this paper develops an empirical model to allow for imperfect competition in the market for traded goods a simultaneous equation model incorporating the demand for and supply of taiwanese footwear exports to the united states is specified and estimated the model allows the identification of two separate sources of mark ups in export prices the first comes from the u s imposed quantitative restriction on these exports the second comes from imperfect competition in the international market for these exports the results suggest competitive behavior by taiwanese footwear exporters the quantitative restriction resulted in a 16 9 percent mark up of prices over marginal cost

a cross country tabulation of own price elasticities of demand abstract this paper tabulates frisch slutsky and cournot own price elasticities for each of 10 goods at the per capita real income levels of 30 countries ranging from india to the united states

product differentiation and the treatment of foreign trade in computable general equilibrium models of small economies this paper examines the treatment of exports and imports and external closure rules adopted in recent single country computable general equilibrium models of small economies the paper presents a simple one sector analytic model which captures the major features of the multi sector counterpart used in applied models the paper derives graphical and algebraic solutions to the model and shows that unlike some earlier external closures this one gives rise to a well behaved price taking economy the model is also useful to illustrate the role of elasticities in popular trade theoretic models that include traded and non traded goods

production quota in multiproduct pacific fisheries abstract assessing the individual firm s technology and costs in a multispecies fishery allows design of a more effective output quota prior to regulation by anticipating and controlling for the firm s regulation induced responses an empirical study of a pacific coast trawl fishery indicates that the firm s flexibility of product decision is tightly constrained by its technology and cost structure hence as the resource stock for the regulated species sablefish deteriorates and the trip quota progressively tightens the firm cannot sufficiently reorganize its product bundle to preclude increasingly large sablefish disposal this defeats the purpose of the production quota

a general equilibrium analysis of foreign exchange shortages in a developing economy an acute shortage of foreign exchange has been a recurring problem for many developing economies this paper reexamines the foreign exchange gap issue and the debate between structuralists and neoclassicists by providing a quantitative assessment of the role of different assumptions about the values of key trade elasticities it also seeks to complement the existing descriptive analysis of the consequences of alternative adjustment mechanisms with a quantitative analysis that indicates the relative importance of different behavioural assumptions and policy regimes the empirical analysis is based on a computable general equilibrium model which is walrasian in spirit and captures price mechanisms market interactions and structural interdependence in a non linear multisector framework the analysis lends support to the structuralist view that it is not sufficient to look at problems of adjustment only at the macroeconomic level

the impact of employment tax cuts on unemployment and wages the role of unemployment benefits and tax structure abstract i model and simulate the effects of employment tax cuts on unemployment and wages in four equilibrium models competitive union bargaining search and efficiency wages i find that if the ratio of unemployment compensation to wages is fixed the effect of the tax cut is mainly on wages but if income out of work is fixed in real terms there are substantial employment effects when wages are determined by bargaining revenueneutral reforms that make the tax more progressive also reduce unemployment thus policy towards unemployment compensation and tax structure are key influences on the effect of taxes on unemployment

how effective are trade barriers an empirical analysis of trade reduction diversion and compression we analyze the effects of trade barriers using highly disaggregated data the level of disaggregation allows us to separate the effects of tariffs and nontariff barriers ntbs into reduction dive

differentiated products and supply controls in the analysis of agricultural policy reform the case of tobacco abstract with a multi market model of the u s tobacco and cigarette industries we analyze the impact of a reduction in the assistance to u s tobacco producers by relaxing production quotas with nonbinding price support and by lowering tariffs on tobacco imports the results show the importance of incorporating differentiated product and supply control assumptions into agricultural policy analysis

the importance of the design of market based instruments for co2 mitigation an age analysis for spain in the past few decades economists have defended the use of market based instruments mbi in environmental and climate policy there have been many papers which have compared the costs of attaining environmental objectives with mbis and with command and control instruments however very few have compared different mbis in examining these costs this paper seeks to analyse various mbis for co2 mitigation from the viewpoint of cost effectiveness using an age applied general equilibrium model for the case of spain a distinction is drawn between 1 quantity instruments which represent different extents of a market for emission permits and 2 price instruments which represent different types of tax each instrument can affect different segments of the emission sources and therefore can have very different effects on the economy as a whole we show how mbi can help to minimise mitigation costs but also how taxes and tradable emission permits that are limited or constrained by many exemptions and distortions can raise costs considerably

labour market outliers lessons from portugal and spain iberian labour markets why spain and portugal are oecd outliers spain has the highest unemployment rate 22 2 of any european union country portugal one of the lowest 7 3 superficially these countries share many labour market features the toughest job security rules in the oecd an apparently similar architecture of wage bargaining and comparable generosity of their unemployment insurance systems at least since 1989 we address the puzzle by examining portuguese and spanish labour market institutions in particular job security unemployment benefits and the system of wage bargaining we then conduct empirical analysis of spanish and portuguese unemployment outflows and wage distributions using micro data we find differences in unemployment benefits non existent in portugal until 1985 and less generous nowadays differences in wage flexibility wage floors by category established by collective agreements are set at a lower relative level in portugal and in practice higher firing costs in spain a key explanation of the difference in portuguese and spanish unemployment rates is the wage adjustment process generous benefit levels may have been necessary for the path spanish unions took but this was not the sole explanation of different wage setting in spain and portugal olympia bover pilar garcia perea and pedro portugal

the relative inefficiency of quotas the cheese case the nonequivalence of tariffs and quotas under a wide variety of circumstances is well established in economic theory this study considers heterogeneity as a source of nonequivalence and demonstrates its practical importance where restriction is inevitable the bias of economists in favor of price instruments is not thoroughly grounded this study should help provide a foundation the point of departure from the equivalence model is differentiation of products

environmental policy and the equilibrium rate of unemployment abstract this paper integrates environmental policy instruments with the theory of equilibrium unemployment we investigate the question of whether a low equilibrium rate of unemployment and a high quality of the environment are complementary policy goals or must be traded off it turns out that an interval exists for a tax on emissions where the two goals are indeed complementary the tax stimulates the emergence of an abatement sector which provides pollution control and vacancies for the job seekers for constrained efficiency the policy maker operates five instruments to internalize the environmental and the search externalities a tax on emissions employment subsidies and recruiting allowances for the polluting industries are sufficient to implement the first best the optimal emission tax is an increasing function of the workers bargaining strength for labor markets where workers have a strong bargaining position the optimal pollution tax may easily exceed the pigouvian tax

the intra country distributional impact of policies to fight climate change a survey abstract in this paper we present a survey of distributional impact analysis of environmental policies with emphasis on taxes envisaged or implemented to reduce greenhouse gas emissions ghg these policies usually aim at reducing ghg directly or indirectly however they can produce important changes in factor allocation relative prices in specific countries as well as on world markets when adopted by a large number of countries changes in welfare can be important for vulnerable groups of population in developing countries this survey reviews the evidence on the incidence of these policies in the process it shows that the computable general equilibrium cge microsimulation approach has not been fully exploited in the context

household labour supply with rationing in spain this paper provides new empirical evidence on household labour supply with rationing to that end we use the latest spanish data in order to estimate three flexible functional forms namely the nles the quadratic and the hausman ruud forms and calculate the income and wage elasticities we find that the number of dependants has a negative effect on the labour supply of the female moreover the north and the east spanish regions have a clearly positive effect on the labour supply of the female whilst the north has the same effect on that of the male the elasticities of three functional forms are very similar male labour supply is slightly decreasing with the wage whilst for the female it is increasing leisure is a normal good for both spouses as expected whilst the labour hours are net substitutes

restricting the market for quota an analysis of tobacco production rights with corroboration from congressional testimony regulatory programs that restrict output levels often impose restrictions on the transfer of rights to produce or to use particular inputs in this paper we use a unique cross section time series data set from north carolina to quantify the welfare effects of transfer restrictions for poundage quota under the u s flue cured tobacco program we find that the deadweight costs of such restrictions are small but that the distributional effects are substantial we analyze congressional testimony on quota transfer legislation and conclude that our estimates of the distributional effects are consistent with expressed views of market participants

the effects of trade liberalisation abstract the liberalisation of agricultural trade has been an important component of the uruguay round of multilateral trade negotiations under the gatt a considerable amount of research effort has been expended on estimating the costs of agricultural protectionism most of this activity has been based on a partial equilibrium framework with conventional quantification of the distributive benefits and costs to be expected from liberalisation attempts at general equilibrium analysis have been fewer but provide evidence of the economy wide gains from the removal of protection whilst these analyses have had a powerful influence on the nature of the political discussions on agricultural trade policy they have not helped define the details of politically acceptable alternatives to current agricultural supports the reasons are the technical economic data and statistical problems which restrict the interpretation of results to broad generalisations and the failure of analyses to focus on the most important political concerns indicating these concerns may help define the focus of future research but it is doubted if conventional economic analysis has very much more to offer

green fiscal reform and employment a survey in the european debate an increase in employment is generally regarded as an important extra dividend in addition to improved environmental quality from environmental taxes the scope of this paper is to evaluate going through the existing empirical literature if and to what degree this result could be achieved through a green fiscal reform a further goal of this paper is to assess which taxes are more efficient in terms of employment creation when they are utilized for recycling back to the economy the revenue flowing from environmental taxes this kind of exercise is largely different from the theoretical analysis of the double dividend issue a large quantity of literature has grown during the recent years according to this approach but this version of the double dividend theory will be disregarded in this paper

energy taxation in a small open economy social efficiency gains versus industrial concerns welfare analyses of energy taxes typically show that systems with uniform rates perform better than differentiated systems especially if revenue can be recycled by cutting taxes that are more distortionary however in practical policy efficiency gains must be traded off against industrial concerns presumably energy dependent industries of small open economies will suffer relatively more if taxed this computable general equilibrium cge study examines the social costs of compensating the energy intensive export industries in norway for their profit losses from imposing the same electricity tax on all industries the costs are surprisingly modest this is explained by the role of the nordic electricity market which is still limited enough to respond to national energy tax reforms thus an electricity price reduction partly neutralizes the direct impact of the tax on profits in addition we examine the effects of different compensation schemes and find significantly lower compensation costs when the scheme is designed to release productivity gains

low carbon transition in a coal producing country a labour market perspective abstract the decarbonisation of energy in a coal producing country involves phasing out the coal sector and reducing employment in coal mining our case study of poland reveals that in the past half of the workers that left the mining sector failed to move to other sectors and left the labour market this could be explained by the lower education levels of miners and lower wages in other sectors relative to mining we use a mathematical model to demonstrate that if ex miners fail to move to green or neutral sectors decarbonisation involves a net loss of the labour force regardless of the number of jobs created in the green sector the loss of labour constitutes a macroeconomic cost that must be added to changes in energy system costs the size of the cost does not depend on whether reduction of emissions is achieved by the substitution of coal with renewable energy sources or by an increase in energy efficiency the size of the cost is largest when the reduction of emissions is achieved by replacing coal with imported gas finally we demonstrate how costs related to the imperfect transition of labour could be taken into account in numerical general equilibrium models

price discrimination and markups in export markets abstract imperfect competition in international markets is one of the key explanations for why prices of similar goods might differ among destination countries this paper develops an empirical model to examine the presence of price discrimination stemming from imperfect competition in the international market for a country s exports the model is used to examine the export behavior of taiwanese exporters of footwear the generalized supply relation allows identification of deviations from competitive pricing in each export market in addition the model provides insights into the extent of exchange rate pass through finally the model is modified in order to estimate the effect of the voluntary export restraint imposed in the u s on footwear imports from taiwan

trade democracy and the gravity equation abstract does democracy affect trade there are several channels by which democracy may affect trade with differing implications first democratization in the exporting country can improve product quality and reduce trade costs increasing bilateral trade second democratization in the importing country may increase trade barriers and thus reduce imports in this paper i analyze the effect of democracy on trade by augmenting the gravity equation with democracy using a rich panel data set and controlling for the endogeneity of democracy i find empirical evidence consistent with the hypothesis that democracy fosters trade this finding is robust to various econometric methods and to the use of disaggregated specifications

does the central american common marke1 benefit its members does the central american common market benefit its members i introduction the members of the central american common market cacm have recently taken measures to revitalize their union they have formally pledged to improve regional economic integration and they have reinforced the common external tariff they took these measures in the belief that a stronger union would improve their economic welfare a belief that has also led both the united states and the european community to support a stronger union the idea that a regional trading group would improve economic welfare of the central american countries originated in the early 1950s when raul prebisch and other economists in the united nations economic commission for latin america ecla argued persuasively that such a union would help these countries develop their economies to many the views of the ecla economists were vindicated when the inceptionof the cacm in 1960 was followed shortly by accelerated economic growth in the region further support for their views came from quantitative studies cline and delgado 1978 willmore 1976 yotopoulos and nugent 1976 nugent 1974 and wilford 1970 which all concluded that the union provides static welfare gains for its members there is however room for skepticism about the benefits of the cacm much of the argument of the ecla economists is based on the notion that import substitution is a good way to promote economic development a notion that has since fallen into disrepute nor does the accelerated growth that followed the union s formation provide strong evidence that the cacm provides benefits the volume of trade between members is too small for the union to have had more than a minor effect on the region s economy so even if this effect were negative the region would presumably still have grown rapidly in the mid 1960s the evidence from the quantitative studies is also faulty these studies did not estimate directly the effects of the cacm but merely imputed these effects by assuming either that market shares or income elasticities would have remained constant without the union furthermore they assumed that supplies of different countries are perfect substitutes for each other whereas recent studies by collier 1979 grossman 1982 and anderson 1985 have shown that the degree of substitutability in demand between these supplies is important in determining how customs unions and other discriminatory tariff changes affect welfare it is particularly important to allow for less than perfect substitutability when analyzing the cacm because member imports from developed countries often have no close substitutes among locally produced goods in this paper the static welfare consequences of the cacm are reexamined with two important advances over the previous studies first direct estimates are made of the effects of the union second the shortcomings of the perfect substitutes assumption are overcome by allowing imports from different countries to be imperfect substitutes for each other and for domestic output the model which is partial equilibrium in nature also enjoys two advantages over the computable general equilibrium models such as those whalley 1985 and hamilton and whalley 1985 used to examine the effects of various economic integration schemes it requires fewer data and its operation is more transparent so it shows more clearly how introducing imperfect substitutes alters the traditional analysis of a customs union the model s main limitation is that it applies only to customs unions among small countries ii the model geometric presentation figures 1 2 and 3 show the home market and figure 4 the export market for country a a representative member of the cacm a s residents distinguish between four goods imports from other members imports from nonmembers domestic output for home consumption and exports

reference point dependence and specification bias abstract issues of specification bias arise in deterministic as well as in econometric models this paper shows that such biases depend on the reference point used to evaluate them using numerical general equilibrium models in which the incorporation of quality upgrading in the competitive case increases or reduces the welfare costs of trade barriers depending upon whether a trade distorted equilibrium or free trade is used as the reference point

quotas as options quota licenses are options their price is given by expected discounted future value which hangs on the possibility that the quota may bind a number of auxiliary administrative details of quota systems are also analyzed in this context the presence of use it or lose it requirements and of restrictions on rate of usage of the annual quota can be seen as attempts to offset the implied protection on below limit imports they are shown to be inefficient recognition of the option valuation of quota licenses is rich with suggestions for future work on evaluation of quotas and comparisons with alternative schemes for protection

the measurement of income and price dispersion in cross country demand analysis abstract measures are formulated for the dispersion of real income and relative prices across countries they are applied to 30 countries in 1975 for 10 groups of consumer goods

income elasticities at different price vectors abstract cross country data are used to evaluate the income elasticities of the demand for ten broad groups of goods at two different price vectors the observed prices of separate countries and the geometric means of these prices across all countries the major effect is on the income elasticity of the demand for food using observed rather than geometric mean prices results in lower elasticity values for the more affluent countries

tax reform structural unemployment and the environment the effects of environmental tax reform i e using the proceeds of a higher energy tax rate to lower the labour tax rate on wage formation employment and environmental quality are analysed in the context of a small open economy with structural unemployment caused by hiring costs we find that such a reform may boost employment if it shifts the tax burden away from workers towards those without employment in the formal sector environmental tax reform succeeds in shifting the tax burden away from workers in the formal sector if higher energy taxes reduce earnings in the informal sector by reducing labour productivity

taxes and the quality of capital abstract this paper shows that tax policy toward investment by changing the relative prices of capital varieties even within narrow classes of equipment can have a direct effect on the quality composition of capital goods that firms purchase detailed data on farming mining and construction machinery suggest that this impact is economically important firms significantly shift investment toward higher quality varieties when they receive investment subsidies and do not do so when investment is high for other reasons in the aggregate all of the new investment generated by tax subsidies appears to come from firms shifting to higher quality capital goods rather than buying a larger number of their existing capital types the paper also applies a methodology for calculating the implied deadweight loss from the quality distortion and shows that its magnitude may represent a substantial efficiency cost from capital taxation that is neglected in conventional work

measuring the distance between relative price vectors of different countries abstract a simple measure is developed for the distance between relative price vectors it is applied to cross country data the procedure also provides a justification for the use of geometric mean prices in cross country demand analysis

world product and income international comparisons of real gross product the volume reports on the third phase of the united nations international comparison project icp the main results provide comparisons of real gross domestic product gdp per capita for thirty four countries in 1975 quantity and price comparisons are given also for personal consumption capital formation and public consumption and further subdivisions of final expenditures on gdp are estimated

economic issues in tariffication an overview abstract the agricultural trade liberalization proposal known as tariffication aims at converting all existing non tariff barriers ntbs to trade into bound tariffs and to reduce these tariffs over time this is in tune with the original philosophy of the general agreement on tariffs and trade gatt and it calls for a dramatic overhaul of existing agricultural policies in many developed countries the main economic issues that arise with tariffication stem from the non equivalence of tariffs and ntbs in a number of scenarios this paper analyzes non equivalence arising from the existence of imperfect competition in importing countries price instability in importing and exporting countries and inefficient allocation of quantitative restrictions it is shown that in all these cases the definition of an appropriate equivalent tariff to be used in tariffication is not straightforward and that in general this equivalent tariff cannot be computed on the basis of only observed price differences between countries tariff rate quotas which are meant to be the main tool of implementation of tariffication according to the existing proposal are analyzed in some detail concerning the relationship between tariffication and the other elements of the trade liberalization package it is shown that tariffication would limit the scope of export subsidy policies it is also shown that the existence of production and export subsidies makes observed price gaps between countries of questionable value in setting equivalent tariff levels finally it is argued that the main focus of tariffication should be the conversion of ntbs to acceptable long run bound tariffs rates and considerable flexibility in this conversion process could be exercised in the transition period
