an empirical analysis of life cycle fertility and female labor supply this paper examines us household fertility and female labor supply over the life cycle using data from the panel study of income dynamics the authors investigate how maternal time inputs and market expenditures on offspring as well as the benefits they yield their parents vary with ages of offspring and influence female labor supply and contraceptive behavior the econometric framework combines a female labor supply model and a contraceptive choice index function it also accounts for the fact that conceptions are not perfectly controllable events using longitudinal data on married couples the authors estimate these equations and test alternative specifications of the technologies governing child care the findings suggest that while parents cannot perfectly control conceptions variations in child care costs do affect life cycle spacing of births furthermore the results demonstrate the gains of modeling the linkages between female labor supply and fertility behavior at the household level authors modified

the drawbacks and opportunities of carbon charges in metropolitan areas a spatial general equilibrium approach in cities there is a variety of economic and spatial forces that may influence to what extent a travel related co2 emission pricing can be an effective instrument to contribute to the achievement of co2 reduction goals therefore we examine the effectiveness and impact of co2 emission charges using a spatial general equilibrium model of an urban economy calibrated according to an average german city our analyses suggest that the imposition of a pigouvian type co2 emission charge on urban passenger travel may be able to reduce emissions by about 1 11 depending on the estimated social damage cost of carbon dioxide such a policy increases urban welfare mainly on account of a reduction of congestion costs however pricing congestion directly not only provides higher urban welfare but also higher emission reductions pricing congestion and co2 emissions simultaneously allows to achieve a wide range of emission reduction goals if however the reduction goal is very ambitious the emission charge must be raised to higher levels then distortions in the urban markets and in spatial travel decisions lower labor supply and thus urban production income of city residents federal tax revenue income of landowners outside the city all together implying losses in welfare

monopolistic quantity rationing in this paper we address the question of whether a price setting monopolist can improve his welfare by imposing quantity constraints on buyers we show first that if all buyers are identical quantity rations are not useful for the monopolist we then show by means of an example that if buyers are diverse quantity rations may be desirable it is shown that if there are only two commodities the only constraint that may be useful to the monopolist is a zero constraint on one of the two commodities an example shows that this property does not hold for more than two commodities

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

marginal tax reform externalities and income distribution the paper examines welfare improving and revenue neutral directions marginal policy reforms for an economy with nonidentical individuals and an externality that has a feedback effect on the consumption of taxed goods it considers three types of policy instruments the indirect taxes the uniform poll transfer and public abatement this extends the framework set up by ahmad and stern 1984 bovenberg and de mooij 1994 and schob 1996 the theoretical model is illustrated for a specific externality namely congestion caused by peak car transport

carbon tax simulations using a household demand model abstract the main objective of this paper is to analyse consumer response and welfare effects due to changes in energy or environmental policy to achieve this objective we formulate and estimate an econometric model for non durable consumer demand in sweden that utilises micro and macro data in the simulations we consider two revenue neutral scenarios that both imply a doubling of the co2 tax one that returns the revenues in the form of a lower vat and one that subsidise public transport one conclusion from the simulations is that the co2 tax has regional distribution effects in the sense that household living in sparsely populated areas carry a larger share of the tax burden

taxing family size and subsidizing child specific commodities abstract the effects and optimal choice of policy instruments directly affecting the welfare of parents and children are examined within the context of a household economics model if fertility were exogenous and households differed in number of children only a first best could be implement through a grant conditional on family size outside this very special case public intervention is either not justifiable on distributional grounds or involves taxing child specific commodities less than adult specific commodities if fertility is endogenous family size must be taxed or subsidized according to whether household expenditure on children is decreasing or increasing in the mother s wage rate

on the taxation of trade within and between households abstract tax reform proposals affect individual welfares in ways which strongly depend on the nature of specialisation in household production and the pattern of trade within households variation in the degree of specialisation in domestic production across households strongly influences the impacts on individual tax burdens of a given tax reform the standard models of the economics literature cannot be used to analyse these issues because they ignore the two person nature of households and the existence of household production and trade this paper proposes a simple and tractable model to remedy this and uses it to analyse the impacts of the types of tax reform that have been the subject of recent policy debate

keynesian unemployment as a nash equilibrium with endogenous wage price setting an example abstract a simple 3 good 1 consumer 1 firm model of fixed price quantity constrained equilibrium is developed a game is then defined on the set of globally unique equilibria the consumer sets the money wage the firm sets the money price of output money is numeraire nash solutions of the game exist and may involve keynesian unemployment but never involve classical unemployment or repressed inflation

intercountry comparisons of labor force trends and of related developments an overview this paper is a survey of analyses of women s labor force growth in 12 industrialized countries originally presented at a conference in sussex england in june 1983 the main focus of the conference papers and of the current survey is on growth of the labor force of married women in the years 1960 80 trends in fertility wages and family instability also receive attention as related developments married women s labor force growth is observed in all countries except for the ussr after 1970 where labor force rates of women reached the level of men growth rates differ among countries they apparently respond to growth in real wages and to growth in education but response elasticities differ among countries estimates of these elasticities contained in the country papers were helpful in predicting the trends other findings include ubiquitous declines in fertility and growth of divorce in the 1970s both developments are related to long run labor force growth in all countries wages of women were lo

fertility taxation and family policy historically there is clear evidence of an inverse relationship between female labour supply and fertility however the relationship across countries is now positive countries like germany and italy with the lowest fertility also have the lowest female participation rates this paper analyses the extent to which this can be explained by public policy in particular taxation and the system of child support the results suggest that countries which have individual rather than joint taxation and which support families through child care facilities rather than child payments are likely to have both higher female labour supply and higher fertility

the effects on competitiveness of coordinated versus unilateral fiscal policies reducing ghg emissions in the eu an assessment of a 10 reduction by 2010 using the e3me model abstract international competitiveness effects from coordinated and uncoordinated multilateral policies to reduce co 2 emissions from 11 member states of the eu by 2010 are compared with those from unilateral policies to achieve a 10 cut in each member state alone the paper presents the results from four projections using a large scale integrated regionalised e3 model of the eu estimated on time series cross section data 1968 93 with international trade treated as between each member state and a european transport and distribution network the 10 reduction is achieved by additional excise duties incremented every year 1999 to 2010 according to the carbon contents of fuels with special with special treatment of electricity taxed on outputs not inputs with revenues recycled via reductions in employers social security contributions multilateral coordinated policies require a common tax rate of 156 ecu per tonne carbon 1999 prices which rises to an average of 165 ecu per tonne with a wide range between regions when policies are uncoordinated all the tax shift projections show double dividends for emission reduction and employment gain for all member states unilateral policies do not show much carbon leakage but they show smaller gains for output and employment effects for price competitiveness appear to be small and mixed with serious losses appearing only for the netherlands and for metals and chemicals especially for unilateral action

application of computable general equilibrium cge to climate change mitigation policy a systematic review abstract with the growing literature related to climate change mitigation measures and policy interventions a systematic review of the application of computable general equilibrium cge model is inevitable therefore this article aims to characterise the relevant studies define a comparative framework to identify the current state of the art and the gaps in applied general equilibrium models firstly the systematic review found a total of 301 research articles from scopus and web of science databases and finally analysed 154 articles based on inclusion and exclusion criteria from 67 refereed journals the review analysis found that application of cge model is very vital in addressing climate change mitigation issues at the national regional and global levels however china attracted the most substantial research interests followed by the usa india and australia among others which are in line with their share of greenhouse gas emissions in the world most of the research themes focus on the carbon tax emission reduction target emission trading renewable energy energy efficiency and carbon capture and storage as primary drivers of low carbon economy nevertheless there is a trend of employing more static cge model compared to the dynamic cge although application of the latter has a limitation of providing right inputs to the macroeconomic policy finally research directions and gaps envision other complementary models such as dynamic stochastic general equilibrium dsge and agent based model abm for proper policy interventions

imperfect competition and fixprice equilibria under consumer aggregation and net substitutes the general question posed here and in a companion paper is under what conditions do models of imperfect competition generate equilibria which are also fixprice equilibria answers to this question are provided for the cournot walras general equilibrium model originated by gabszewicz and vial 1972 and the model of a quantity constraining monopolist due to bohm et al 1983 whereas our earlier paper derived results for other models from gross substitute complement assumptions here we also offer results based on net substitute complement assumptions plus appropriate aggregation of consumers this note thus extends the earlier paper by analyzing different models using different techniques the net substitute complement classification used is the inverse net or hicksian q classification described in section ii for the sake of brevity the discussion of the models in sections iii and iv restricts attention to equilibria where price and consumption vectors are strictly positive notation and definitions are those of the earlier paper cf madden and silvestre 1991 section ii

jointly determined saving and fertility behaviour theory and estimates for germany italy uk and usa abstract the comparative statics predictions of models of the joint determination of household saving and fertility are derived under various hypotheses self interest altruism of parents towards children altruism of children towards parents etc and compared with those of models which determine saving under the assumption of exogenous fertility country specific saving and fertility equations are then estimated using time series data for germany italy uk and usa for each of the countries considered the estimates are consistent with the hypothesis that saving and fertility are jointly determined by self interested parents and reject the alternative hypotheses the data also show that a self financing expansion of social security discourages fertility and generally raises household saving

income distribution policies with endogenous fertility the implications of endogenous fertility for intra generational welfare comparisons of alternative policies with respect to income taxation and family allowances are considered the interactions among the choices between leisure options labor force participation and fertility are shown to be crucial to the determination of both the signs and the magnitudes of the optimal child allowances and income tax rates the implications of a negative marginal tax rate and a negative child allowance are considered annotation

analysing gasoline demand elasticities a survey this paper is a survey of studies on gasoline demand although there are very many dxerent studies in this eld which sometimes appear to arrive at contradictory results we find that with proper stratification of studies by model and data type much of the contict turns to consensus in this survey we classtfy studies by data type and by ten d erent categories of model and with the exception of estimates on seasonal data which tend to be unstable and of certain inappropriate model formulations we find a fair degree of agreement concerning average short run and even long run income and price elasticities

household transport demand in a cge framework the main objective of this study is to improve the modelling of household demand for transport services in a computable general equilibrium cge model the new extended model is then used for numerical calculations to test how the swedish economy reacts to a carbon target special attention will be given to distributional effects and the connection between labour supply and work journeys in a sparsely populated country like sweden a differentiation between trip purposes and trip length a complementary relationship between work journeys and labour supply and a subdivision of households by density of population and income influence the numerical results our main conclusions from the analysis of a carbon target are that if the carbon tax revenue is recycled by decreasing the employers social contribution fee welfare costs are lower than with lump sum replacements of tax revenue to households the welfare cost may be reduced even further if work journeys are not additionally taxed as compared to the base year however the lower total welfare cost is obtained at the expense of making society more unequal since both labour tax recycling cuts in employers social contributions and exempting tax on work journeys will make low income groups carry a higher burden an increased carbon dioxide tax is also shown to increase welfare differences between sparsely populated areas and city regions in sweden

transport tax reform commuting and endogenous values of time abstract we consider a model of urban transport with two trip purposes commuting assumed perfectly complementary to labour supply and noncommuting to analyse the effects of transport tax reform on the value of time and marginal external congestion costs higher commuting taxes plausibly reduce time values but higher noncommuting transport prices will typically raise the value of time the intuition for this latter finding is that the reduction in congestion that follows from the tax increase itself raises net wages per hour of work inclusive of commuting time empirical illustrations with belgian data show a potentially large effect of transport tax reform on time values in quite a few of the tax reforms studied traffic levels are reduced but the increase in time values implies that marginal external congestion costs actually increase

intra household resource allocation an inferential approach if household income is pooled and then allocated to maximize welfare then income under the control of mothers and fathers should have the same impact on demand with survey data on family health and nutrition in brazil the equality of parental income effects is rejected unearned income in the hands of a mother has a bigger effect on her family s health than income under the control of a father for child survival probabilities the effect is almost twenty times bigger the common preference or neoclassical model of the household is rejected if unearned income is measured with error and income is pooled then the ratio of maternal to paternal income effects should be the same equality of the ratios cannot be rejected there is also evidence for gender preference mothers prefer to devote resources to improving the nutritional status of their daughters fathers to sons

imperfect competition and fixprice equilibria when goods are gross substitutes it is possible in principle that the price quantity pair generated by a model of imperfect competition may satisfy the conditions voluntary trading and absence of frictions for a fixprice equilibrium it is shown that imperfect competitors will typically satisfy voluntary trading provided that appropriate gross substitute assumptions are satisfied hence such assumptions are seen to ensure that the solutions of some well known imperfectly competitive general equilibrium models are indeed fixprice equilibria thus bringing together two important traditions in theoretical microeconomics copyright 1991 by the editors of the scandinavian journal of economics

the consumption tax in the presence of altruistic cash and human capital bequests with endogenous fertility decisions abstract we provide an analysis of the consumption tax policy in the presence of cash bequests human capital investments in children and endogenous fertility decisions it is shown that the consumption tax is no longer neutral if the tax rate is constant over the taxpayer s life cycle labor supply is exogenous and the parent expects the offspring to pay the same tax rate if the number of children is chosen optimally by the parent neutrality breaks down because the shadow prices of both bequests and fertility are interlinked it is more expensive to produce a child the larger either bequest is and it is more expensive to make a bequest of either type to each child the larger the number of children produced several examples are provided where imposing the consumption tax induces an increase in the number of children produced and a decrease in net capital formation

fertility and the tax benefit system a reconsideration of the theory of family taxation the author examines the simultaneous nature of the decision to have children the decision to spend money on them and the decision to seek employment it will be argued that the children income trade off emphasised by the present paper is more relevant to most family decisions than the income leisure trade off on which much of the policy debate has been centred in order to do that we shall bring together the recently developed economic theory of the family or new home economics with the microeconomic branch of the theory of public finance a model of family choice is developed the main message of the present paper is that if as the evidence suggests parents have some control over the number of children they put into the world then the effect of taxes and subsidies on the familys allocation of time and money will be generally weaker and in some respects the opposite of what it would be if the number of children were physiologically constrained or exogenously given another is that if parents derive utility from having children this has to be taken into account in any welfare calculation fertility may thus affect the design of optimal policy in two ways indirectly through its effect on market behaviour and directly through its effect on welfare excerpt

taxation unemployment and growth dynamic welfare effects of green policies abstract this paper analyzes the effects of environmental tax reforms on a small open economy the labor market is characterized by union wage setting the carbon tax acts as an implicit tariff which gives rise to terms of trade gains the terms of trade effect together with the union wage setting leads to a positive relationship between the capital labor ratio and net foreign wealth in the short run the disinvestments in real and financial capital give temporary room for higher consumption and instantaneous utility the long run effect on instantaneous utility is more uncertain a strong double dividend may exist

transport taxes with multiple trip purposes a congestible urban transport system is considered in which cars and buses are used for commuting and non commuting trips commuting is a strict complement to taxable labour supply the optimal tax structure for raising a given amount of government revenue is examined for the cases where differentiation of transport tolls between trip purposes is and is not possible an application to belgian urban environments shows that optimal toll differentiation produces significant efficiency improvements without differentiation reforming transport taxes generates substantial gains only when the labour tax can be reduced

transfers to families with children as a principal agent problem abstract the relationship between government and parents is modelled as a principal agent problem with the former in the role of principal and the latter in that of agents we make four major points the first is that if the well being of the child depends not only on luck but also on parental actions that the government cannot readily observe the latter can influence parental behaviour by conditioning income transfers to families on child performance the second point is that if there are market inputs into the making of a happy or successful child which the government can observe but not ascribe to any particular parent or child because they are bought anonymously an income transfer policy can be usefully complemented by an indirect subsidy on the price of these inputs the third is that if parents care about their children incentive considerations may have to be tempered by the need to compensate those who have the misfortune of getting a child with low ability the fourth is that parents can be induced to have the socially desirable number of children by making the transfer conditional not only on child performance but also on number of children ways of making these findings operational and the effects of administrative costs are discussed in some detail
