distributional effects of a carbon tax in broader u s fiscal reform abstract this paper analyzes the distributional implications of an illustrative 15 carbon tax imposed in 2010 on carbon in fossil fuels we analyze its incidence across income classes and regions both in isolation and when combined with measures that apply the carbon tax revenue to lowering other distortionary taxes in the economy consistent with earlier findings we find that a carbon tax is regressive using tax swap simulations we then subtract the burden of other taxes the carbon tax revenue could displace and compute the net effect on households under three assumptions about how capital and labor income might be distributed

uncertainty and monetary policy in a wage bargaining model in a wage bargaining model increased uncertainty concerning monetary and real aggregates is shown to give rise to a higher equilibrium unemployment rate moreover the equilibrium unemployment rate is found to depend on the choice of monetary policy regime as this choice affects the uncertainty wage setters face when setting the nominal wage rate it is also shown that the equilibrium inflation rate may depend on uncertainty in such a way that increased uncertainty gives rise to a higher equilibrium unemployment rate as well as a higher equilibrium inflation rate or what has been called stagflation

endogenous unions and governments a game theoretic approach abstract this paper applies some elements of game theory to the determination of government spending and wages within a simple macroeconomic framework where these variables are ordinarily treated as exogenous in the short run by showing how nominal wages respond to increased government spending and taxes and vice versa the paper attempts to explain the simultaneous tendency of many western economies toward persistent inflation and expansion of the public sector in particular the paper stresses the macroeconomic consequences of the interaction between endogenous utility maximizing governments and labour unions and shows how the response of the economy to changes in government and union behaviour depends on the preferences of both parties with respect to inflation employment real disposable wages and government spending as well as on their view of the relative magnitude of the employment and price effects of such changes

the carbon implications of declining household scale economies in the united states average household size decreased significantly over the past half century from 1950 to 2010 the number of households increased 72 faster than population size in this paper we consider how this drift toward more and smaller households occurring alongside rising affluence undermines efforts to curb carbon dioxide co2 emissions by eroding household scale economies of consumption and associated co2 emissions to estimate the household scaling of co2 emissions we link consumer expenditure data to an economic input output life cycle assessment model we find that the co2 scaling benefits of cohabitation are compellingly large with the carbon footprint of a representative person cohabiting with others being 23 less on average than if that same person lived alone additionally we find that household scale economies 1 decrease in income reflecting the rise in the percentage of household expenditures devoted to more rival goods and services and 2 increase intuitively in household size reflecting the direct expenditure sharing benefits of cohabitation the combined downward pressure on scale economies from declining household size and rising incomes typifying the trajectory of developing societies toward more and smaller households and rising affluence places significant upward pressure on co2 emissions globally

classical unemployment accommodation policies and the adjustment of real wages a model of wage formation and stabilization policy in economies with strong trade unions is developed the analysis provides a theoretical underpinning for the assertion that accommodation policies may cause wage inflation and ultimately reduce employment various methods of accomplishing a real wage adjustment are discussed i a policy of complete nonaccommodation 2 continued accommodation policies but with lower employment targets 3 social contracts and 4 tax based incomes policies tip

an integration of trade union models in a sequential bargaining framework this paper aims to embed two popular models of trade union behavior the monopoly model and the efficient bargaining model in a more general framework it does this by analyzing sequential bargaining models where wages are determined before employment and the power of the union in the two stages of the bargain differs as well as finding that the monopoly and efficient bargain models are special cases of this model a new class of models is also discovered this framework is used to analyze the relationship between union pow er and efficiency the empirical analysis of trade unions and the effects of trade union legislation copyright 1987 by royal economic society

union militancy external shocks and the accommodation dilemma stabilization policy under centralized wage setting is represented as a noncooperative game between an encompassing union and the government the dilemma of the government is whether or not to accommodate supply disturbances when it cannot tell if they are due to an intentionally militant wage policy or unforeseen external price shocks in a single round of wage setting there is no government strategy which can both guarantee full employment and prevent union militancy in a repeated game however there exists a conditional accommodation policy which permits accommodation of supply shocks while inducing the union to refrain entirely from a militant wage policy

majority voting with single crossing preferences we clarify and extend a number of sufficient conditions for the existence of a majority voting equilibrium on one dimensional choice domains these conditions variously stated in the previous literature all impose order restrictions on voter preferences for instance monotone marginal rates of substitution which we show to imply or be equivalent to a general ordinal version of the single crossing condition this simple property is economically intuitive and easily checked in applications this ease of application is demonstrated through an examination of voting models of redistributive income taxation and trade union bargaining behaviour

on the marginal welfare cost of taxation this paper develops a rigorous partial equilibrium analysis of the determinants of margin al welfare cost mwc of taxes on labor earnings it shows that four key parameters interact to determine the magnitude of mwc using aggregate data and plausible ranges of values for the parameters mwc can vary from under 10 percent to more than 300 percent of marginal tax revenue intermediate parameter values sugge st mwc is in the 25 50 percent range however the more extreme estimates cannot be ruled out on the basis of available evidence suggesting that mwc cannot yet be copyright 1987 by american economic association

how robust is the microeconomic theory of the trade union this article argues that the predictions of standard trade union models and the tests for distinguishing between these models are not robust to quite small and reasonable changes in the conventional assumptions in particular it considers the effect of assuming that the ex post substitutability between labor and capital is less than the ex ante substitutability the paper shows that much of the conventional wisdom about the effects of trade unions is not necessarily true in this framework

income growth and atmospheric pollution in spain an input output approach abstract the relationships between economic growth and environmental pressures are complex since the early nineties the debate on these relationships has been strongly influenced by the environmental kuznets curve hypothesis which states that during the first stage of economic development environmental pressures increase as per capita income increases but once a critical turning point has been reached these pressures diminish as income levels continue to increase however to date such a delinking between economic growth and emission levels has not happened for most atmospheric pollutants in spain the aim of this paper is to analyse the relationship between income growth and nine atmospheric pollutants in spain in order to obtain empirical outcomes for this analysis we adopt an input output approach and use namea data for the nine pollutants first we undertake a structural decomposition analysis for the period 1995 2000 to estimate the contribution of various factors to changes in the levels of atmospheric emissions and second we estimate the emissions associated with the consumption patterns of different groups of households classified according to their level of expenditure

labor union objectives and collective bargaining we consider a model oflabor union behavior in which workers make decisions about wages and employment by simple majority rule we show that under general conditions such a union has a well behaved objective function different from those previously postulated in the literature we then show that the union s majority preferences generally lack a von neumann morgenstern utility representation and thus cannot be inserted into traditional bargaining models we then develop and characterize the solutions to a new bargaining model that is consistent with the structure of union preferences several comparative statics results are presented

distributional impacts of carbon pricing a general equilibrium approach with micro data for households article i nfo many policies to limit greenhouse gas emissions have at their core efforts to put a price on carbon emissions carbon pricing impacts households both by raising the cost of carbon intensive products and by changing factor prices a complete analysis requires taking both effects into account the impact of carbon pricing is determined by heterogeneity in household spending patterns across income groups as well as heterogeneity in factor income patterns across income groups it is also affected by precise formulation of the policy how is the revenue from carbon pricing distributed as well as the treatment of other government policies e g the treatment of transfer payments what is often neglected in analyses of policy is the heterogeneity of impacts across households even within income or regional groups in this paper we incorporate 15 588 households from the u s consumer and expenditure survey data as individual agents in a comparative static general equilibrium framework these households are represented within the mit usrep model a detailed general equilibrium model of the u s economy in particular we categorize households by full household income factor income as well as transfer income and apply various measures of lifetime income to distinguish households that are temporarily low income e g retired households drawing down their financial assets from permanently low income households we also provide detailed within group distributional measures of burden impacts from various policy scenarios

a political economy theory of fiscal policy and unemployment this paper presents a political economy theory of fiscal policy and unemployment the underlying economic model is one in which unemployment can arise but can be mitigated by tax cuts and public spending increases such policies are fiscally costly but can be financed by issuing government debt policy decisions are made by a legislature consisting of representatives from different political districts the theory provides a positive account of the simultaneous determination of fiscal policy and unemployment the most important implication of the theory is that debt and unemployment levels should be positively correlated some evidence in support of this prediction is provided using data from a panel of developed countries

trade unions nonneutrality and stagflation the claim that in policy games nonneutrality and a stagflation bias emerge in equilibrium if the unions care about inflation per se is discussed this assumption is shown to be not necessary to obtain a stagflation bias the same applies to nonneutrality if a government acts in the economy the question of whether unions should be envisaged as institutions i e interested in variables unrelated to wages and employment is also addressed two model based alternatives providing microeconomic foundations versus macroeconomic foundations to unions behaviour are presented the conclusion is that the modelling of unions remains an unsettled problem

the impact of a carbon tax on inequality abstract climate change and economic inequality are inextricably linked despite widespread agreement among researchers and policymakers that a carbon tax is the most efficient mechanism to curb greenhouse gas emissions such a tax exacerbates inequality since low income households spend a greater share of their income on carbon intensive goods using input output tables and detailed expenditure data for the united states we estimate households carbon footprints and examine the impact of a revenue neutral tax of 50 per ton of co2 on multiple forms of inequality devoting carbon tax revenue to fund a carbon dividend makes the policy progressive minimizes redistribution among households of similar means mitigates group based inequalities and benefits 56 of people including 84 in the bottom half of the distribution while some researchers have dismissed dividends on efficiency grounds we show that the double dividend typically associated with labor tax cuts is insufficient to protect the purchasing power of a majority of americans

targets for global climate policy an overview a survey of the economic impact of climate change and the marginal damage costs shows that carbon dioxide emissions are a negative externality the estimated pigou tax and its growth rate are too low to justify the climate policy targets set by political leaders a lower discount rate or greater concern for the global distribution of income would justify more stringent climate policy but would imply an overhaul of other public policies catastrophic risk justifies more stringent climate policy but only to a limited extent

governments trade unions and the macroeconomy an expository analysis of the political business cycle we have briefly reviewed the state of the art of research on the political business cycle in the context of a simple textbook model of the macroeconomy it has been demonstrated that the government generated political business cycle vanishes as expectations turn rational even then however non inflationary policies apparently are time inconsistent hence democracies seem to be stuck with some sort of inflationary bias

the interaction of monetary policy and wages this paper focuses on the interaction of monetary policy and wage formation in economies with strong labor unions government and unions are viewed as endogenous utility maximizers and the macroeconomic consequences of their strategic interaction are explored with the aid of some elements of simple game theory specifically it is shown a how labor unions adjust wages to prices so as to maximize their utility following changes in monetary policy b how the effectiveness of monetary policy is circumscribed without necessarily being nullified by the utility maximizing reactions of unions and c how the interplay of government and unions can create a persistent tendency towards inflation and unemployment simultaneously

the effect of wage bargains on the stock market value of the firm the author estimates the change in the value of common stock resulting from an unexpected change in collectively bargained labor costs using bargaining unit wage data and nyse stock returns he estimates a dollar for dollar trade off between these variables this result is consistent with stock valuations based on present value maximizing managerial decisions that is the results are consistent with hotelling s lemma the author also finds support for the hypothesis that collective bargains maximize the sum of shareholder and union member wealth that is the results are consistent with strong efficiency in the contracting environment copyright 1989 by american economic association

unexpected inflation real wages and employment determination in union contracts this paper examines the effect of nominal contracting provisions on employment determination in union contracts in most contracts the nominal wage rate is wholly or partially predetermined real wage rates therefore contain unanticipated components that reflect unexpected price changes and the degree of indexation the empirical analysis based on a large sample of indexed and nonindexed contracts suggests that unexpected real wage changes are associated with systematic employment responses in the opposite direction the author concludes that nominal contracting provisions play a potentially important role in the cyclical properties and persistence of employment movements in the union sector copyright 1990 by american economic association

climate change policy s interactions with the tax system abstract this paper presents a range of insights from recent literature on how climate change policies and other environmental policies interact with the fiscal system it explores four issues associated with fiscal interactions first it examines how these interactions influence the prospects for a double dividend both an environmental improvement and a reduction in the costs of the tax system second it analyzes how the use of revenues from a carbon tax or from a cap and trade system involving auctioned emissions allowances influences these policies economic costs third it addresses the question whether carbon taxes or cap and trade programs represent more efficient sources of government revenue than other more traditional revenue sources such as income sales or payroll taxes finally it analyzes how fiscal interactions affect the choice between co 2 emissions pricing instruments carbon taxes and cap and trade and other climate policy instruments
