estimates of effective marginal tax rates on factor incomes this chapter describes a method of calculating summary measures of effective factor income tax rates in the united states using readily available data the numbers resulting from application of this method in a study are reported in the chapter and some of their possible uses are discussed the estimated factor income tax rates behave over time in a manner quite consistent with the behavior of other broad measures of federal tax policy the postwar movement in the tax rate on income from labor relative to that on income from capital or more accurately the relevant components of these tax rates provides suggestive support for the miller scholes hypothesis that the federal personal income tax has been moving in the direction of a pure consumption tax the tax rates reported in the chapter are consistent with other studies that show a decrease since the 1950s in rates of taxation at the corporate level of income from corporate held capital they are also consistent with the view that rates of taxation of such income at the noncorporate level have risen but not quite sufficiently to offset the decline in the corporate tax burden

fiscal policy coordination with demand spillovers and unionised labour markets we explore the incentives for governments to cooperate by expanding expenditure we have three countries two are in a monetary union the emu the labour markets of both the emu countries are unionised and there is involuntary unemployment in equilibrium we explore the intra and intercountry effects of changes in bargaining power we then examine optimal government expenditures in each emu country we find that there is a positive spillover and that expenditures are strategic complements the coordinated equilibrium involves higher expenditure than the uncoordinated equilibrium

economics psychology and the history of consumer choice theory this paper examines elements of the complex place role influence of psychology in the history of consumer choice theory the paper reviews and then challenges the standard narrative that psychology was in consumer choice theory early in the neoclassical revolution then strictly out during the ordinal and revealed preference revolutions now possibly back in with recent developments in experimental behavioural and neuroeconomics the paper uses the work of three particular economic theorists to challenge this standard narrative and then provides an alternative interpretation of the history of the relationship between psychology and consumer choice theory copyright the author 2009 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

how do fiscal and technology shocks affect real exchange rates new evidence for the united states abstract using vector autoregressions on u s time series relative to an aggregate of industrialized countries this paper provides new evidence on the dynamic effects of government spending and technology shocks on the real exchange rate and the terms of trade to achieve identification we derive robust restrictions on the sign of several impulse responses from a two country general equilibrium model we find that both the real exchange rate and the terms of trade whose responses are left unrestricted depreciate in response to expansionary government spending shocks and appreciate in response to positive technology shocks

international fiscal policy transmission the paper examines international transmission of stochastic fiscal policy disturbances in a two country general equilibrium framework with possible excess supply equilibria with underutilization o

tastes and technology in a two country model of the business cycle explaining international trade on international financial markets allows people to insure country specific risk and smooth consumption intertemporally equilibrium models of business cycles with trade on global financial markets typically yield international consumption correlations near one and excessive volatility of investment the authors incorporate nontraded goods in the model and find that the implications for aggregate consumption investment and the trade balance are consistent with business cycle properties of industrialized countries however the model driven by technology shocks alone yields counterfactual implications for comovements between consumption and prices at the sectoral level taste shocks produce price quantity relationships more consistent with the data copyright 1995 by american economic association

capacity adequacy and revenue sufficiency in electricity markets with wind power we present a computationally efficient mixed integer program mip that determines optimal generator expansion decisions as well as periodic unit commitment and dispatch the model is applied to analyze the impact of increasing wind power capacity on the optimal generation mix and the profitability of thermal generators in a case study we find that increasing wind penetration reduces energy prices while the prices for operating reserves increase moreover scarcity pricing for operating reserves through reserve shortfall penalties significantly impacts the prices and profitability of thermal generators without scarcity pricing no thermal units are profitable however scarcity pricing can ensure profitability for peaking units at high wind penetration levels capacity payments can also ensure profitability but the payments required for baseload units to break even increase with the amount of wind power the results indicate that baseload units are most likely to experience revenue sufficiency problems when wind penetration increases and new baseload units are only developed when natural gas prices are high and wind penetration is low

situation as determinant of selection and valuation this article investigates the proposition that situation is the determinant of selection and valuation it investigates the ways in which various types of situation dictate selections and valuations and contrasts this process with the marginal model of economic theory rational and behavioural approaches to theory are compared it is suggested that situation related selection provides a more realistic account of consumer selection than neoclassical theory the situations that govern choice are seen as established through a process of support bargaining whereby individuals adjust their behaviour and opinions to gain the support of those around them this process forms also the abstract situations embodied in theories about the nature of the world and society the individualism of neoclassical theory is displaced in the process of support bargaining the idea of support bargaining focuses attention on the dependence of neoclassical theory on support to offset its fundamental faults it is suggested that it be replaced with the theory of support bargaining and associated situation related selection

a dynamic analysis of a demand curve based capacity market proposal the pjm reliability pricing model because of high generation adequacy standards in the power industry some peaking capacity operates for a limited time during the year and may not receive sufficient energy revenues to meet its fixed costs this is particularly true when energy prices are capped in order to mitigate market power the northeastern u s independent system operators isos have responded to this issue by establishing capacity obligations for loads and markets for installed capacity thus providing a capacity revenue stream to generators the installed capacity icap markets in the northeastern u s markets are a response to this need for additional incentives to construct generation the federal energy regulatory commission ferc has accepted the pjm interconnection s pjm proposal to replace the present fixed icap requirement that is placed upon load serving entities lses with a demand curve based system in which the iso would be responsible for acquiring residual capacity on behalf of lses the demand curve approach pays more when reserve margins are smaller and provides a reduced incentive for investment when installed reserves are above the target another goal is to make revenues more predictable for generators making investment less costly and ultimately lowering prices for consumers a dynamic representative agent model is presented for projecting effects upon reserve margins generator profitability and consumer costs and is applied to alternative demand curves proposed for the pjm market the consumer costs resulting from a sloped demand curve are robustly lower compared to the present fixed requirement under a wide range of assumptions concerning behavior of generation owners including risk attitudes bidding behavior and willingness to build capacity as a function of forecast profit the cost savings arise from lower capital costs to generators due to reduced risk and risk premiums also average installed capacity is less for the same level of reliability because of reduced fluctuations in installed reserves

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

monetary policy and exchange rate volatility in a small open economy we lay out a small open economy version of the calvo sticky price model and show how the equilibrium dynamics can be reduced to a simple representation in domestic inflation and the output gap we use the resulting framework to analyse the macroeconomic implications of three alternative rulebased policy regimes for the small open economy domestic inflation and cpi based taylor rules and an exchange rate peg we show that a key difference among these regimes lies in the relative amount of exchange rate volatility that they entail we also discuss a special case for which domestic inflation targeting constitutes the optimal policy and where a simple second order approximation to the utility of the representative consumer can be derived and used to evaluate the welfare losses associated with the suboptimal rules

optimal monetary policy in a currency area abstract this paper investigates how monetary policy should be conducted in a two region general equilibrium model with monopolistic competition and price stickiness this framework delivers a simple welfare criterion based on the utility of the consumers that can be used to evaluate monetary policy in a currency area if the two regions share the same degree of nominal rigidity the terms of trade are completely insulated from monetary policy and the optimal outcome is obtained by targeting a weighted average of the regional inflation rates these weights coincide with the economic sizes of the region if the degrees of rigidity are different the optimal plan implies a high degree of inertia in the inflation rate but an inflation targeting policy in which higher weight is given to the inflation in the region with higher degree of nominal rigidity is nearly optimal

commodity trade and international risk sharing how much do financial markets matter abstract this paper evaluates the social gains from international risk sharing in some simple general equilibrium models with output uncertainty a simulation model calibrated to selected moments of u s and japanese data estimates the incremental loss from a ban on international portfolio diversification to be on the order of 0 20 percent of output per year even the theoretical gains from asset trade may disappear under alternative sets of assumptions on preferences and technology the paper argues that the small magnitude of potential trade gains may help explain the apparently inconsistent findings of empirical studies on the degree of international capital mobility

do deployment policies pick technologies by not picking applications a simulation of investment decisions in technologies with multiple applications abstract the role of deployment policies that aim to foster technological change has grown considerably especially in the fields of energy and climate however recent research has shown that the adoption of deployment policies carries the potential of locking in the technology that is most cost effective at the point of policy introduction but may be inefficient in the long term the present paper contributes to the emerging literature on the role of deployment policies in creating path dependency and eventually technology lock in while previous studies focused on the relationship between lock in and the technology specificity of deployment policies this paper introduces a new factor the existence of multiple applications for a technology we argue that this factor is highly relevant for technological lock in and should be considered by policy makers to support our argument we simulate the competition among four stationary battery technologies across energy system applications in an investment simulation model this simulation shows that the degree of competition among technologies differs strongly across applications which corresponds with a highly varying lock in probability hence selecting applications in deployment policies very likely corresponds to selecting technologies we discuss the implications of these results for both policy makers and for the academic debate on deployment policies and technological lock in as well as on technology assessment and governance more generally based on the notion that policies can have different technology specificity levels we develop the idea of the application specificity of policies and provide examples of currently enacted deployment policies that vary in terms of their technology and application specificity

price stability in open economies this paper studies the conditions under which price stability is the optimal policy in a two country open economy model with imperfect competition and price stickiness special conditions on the levels of country specific distortionary taxation and the intratemporal and intertemporal elasticities of substitution need to be satisfied these restrictions apply to both cooperative and non cooperative settings most importantly we show that cooperative and non cooperative solutions do not coincide despite market completeness and producer currency pricing in this framework our analysis suggests a role for international policy coordination

modeling long term dynamics of electricity markets in the last decade many countries have restructured their electricity industries by introducing competition in their power generation sectors although some restructuring has been regarded as successful the short experience accumulated with liberalized power markets does not allow making any founded assertion about their long term behavior long term prices and long term supply reliability are now center of interest this concerns firms considering investments in generation capacity and regulatory authorities interested in assuring the long term supply adequacy and the stability of power markets in order to gain significant insight into the long term behavior of liberalized power markets in this paper a simulation model based on system dynamics is proposed and the underlying mathematical formulations extensively discussed unlike classical market models based on the assumption that market outcomes replicate the results of a centrally made optimization the approach presented here focuses on replicating the system structure of power markets and the logic of relationships among system components in order to derive its dynamical response the simulations suggest that there might be serious problems to adjust early enough the generation capacity necessary to maintain stable reserve margins and consequently stable long term price levels because of feedback loops embedded in the structure of power markets and the existence of some time lags the long term market development might exhibit a quite volatile behavior by varying some exogenous inputs a sensitivity analysis is carried out to assess the influence of these factors on the long run market dynamics

tax disturbances and real economic activity in the postwar united states abstract this paper investigates the macroeconomic effects of cyclical fluctuations in marginal tax rates it finds that systematically including tax variables in a standard real business cycle model substantially improves the model s ability to reproduce basic facts about postwar u s business cycle fluctuations in particular modeling fluctuations in personal and corporate income tax rates increases the model s predicted relative variability of hours and decreases its predicted correlation between hours and average productivity fluctuations in tax rates produce large substitution effects that alter the leisure labor supply decision

fiscal stimulus in times of high debt reconsidering multipliers and twin deficits we investigate the impact of fiscal stimuli at different levels of the government debt to gdp ratio for a sample of 17 european countries from 1970 to 2010 this is implemented in an interacted panel var framework in which all coefficient parameters are allowed to change continuously with the debt to gdp ratio we find that responses to government spending shocks exhibit strong nonlinear behavior while the overall cumulative effect of a spending shock on real gdp is positive and significant at moderate debt to gdp ratios this effect turns negative as the ratio increases the total cumulative effect on the trade balance as a share of gdp is negative at first but switches sign at higher levels of debt consequently depending on the degree of public indebtedness our results accommodate long run fiscal multipliers that are greater and smaller than one or even negative as well as twin deficit and twin divergence behavior within one sample and time period from a policy perspective these results lend additional support to increased prudence at high public debt ratios because the effectiveness of fiscal stimuli to boost economic activity or resolve external imbalances may not be guaranteed

entrepreneurship social mobility and income redistribution in south india development economists have been preoccupied with the problem of increasing the size of the gnp pie to the relative neglect of its distribution despite the recent disenchantment with the viewpoint that all classes share in the benefits of industrial growth empirical data on the distribution of income business opportunity and economic power are in short supply many of the studies on entrepreneurship and economic development when they are not apologetics for ruthless capitalist exploitation as paul baran suggests extol the achievements of the capitalist entrepreneur without examining class origins and monopoly advantage joseph schumpeter sees entrepreneurs irrespective of class origin as heroic figures with the dream and will to found a private kingdom to conquer adversity to achieve success for its own sake and to experience the joy of creation for gustav papanek 1967 the private entrepreneur who is frugal diligent far sighted remarkably able and willing to take political risks is in large part responsible for the success of pakistan in achieving rapid industrialization

real exchange rates and macroeconomics a selective survey the paper discusses real exchange rate issues of industrial and of developing countries for real exchange rates among the key industrial countries we ask what is the best conceptual framework to shed light on this question we look at alternative theoretical approaches and at empirical evidence on the relation among interest rates expectations and depreciation the discussion of developing countries real exchange rates focuses on the link between real exchange rates real wages and the profitability of capital the model highlights the discrepancy between the mobility of capital including in the long run physical capital and

integrating real options analysis with long term electricity market models abstract in liberalized electricity markets the investment postponement option is deemed decisive for understanding the addition of new generating capacity basically it refers to the possibility for investors to postpone projects for a period while waiting for the arrival of new and better information about the market evolution when such development involves major uncertainties the generation business becomes riskier and the investors wait and see behavior might limit the timely addition of new power plants in that sense the literature provides solid empirical evidence about the occurrence of construction cycles in the deregulated electricity industry however the strategic flexibility inherent to the option to defer new power plants has not yet been rigorously incorporated to investment signals in existing market models therefore this paper proposes a novel methodology to assess the long term development of liberalized power markets based on a more realistic approach for valuing generation investments the work is based on a stochastic dynamic market model built upon system dynamics simulation approach the decision making framework considers that the addition of new capacity is driven by the economic value of the strategic flexibility associated with deferring investments under uncertainties thus the value of the postponement option is quantified in monetary terms through real options analysis simulations confirm the cyclical behavior of the energy only market in the long run as suggested by the empirical evidence found in the literature in addition sensitivity analysis regarding some relevant exogenous variables depicts an even more fluctuating evolution of the capacity due to the combination of strong demand growth rates with large volatilities finally the model validity is assessed through a formal procedure according to the scope of system dynamics modeling approach

dynamic modeling of thermal generation capacity investment application to markets with high wind penetration modeling the dynamics of merchant generation investment in market environments can inform the making of policies whose goals are to promote investment in renewable generation while maintaining security of supply such models need to calculate expected output costs and revenue of thermal generation subject to varying load and random generator outages in a power system with high penetrations of wind this paper presents a dynamic investment simulation model where the short term energy market is simulated using probabilistic production costing using the mix of normals distribution mond technique to represent residual load load net of wind output price mark ups due to market power are accounted for an energy only market setting is used to estimate the economic profitability of investments and forecast the evolution of security of supply simulated results for a great britain gb market case study show a pattern of increased relative security of supply risk during the 2020s in addition many new investments can recover their fixed costs only during years in which more frequent supply shortages push energy prices higher

country characteristics and the effects of government consumption shocks on the current account and real exchange rate abstract this paper examines the effects of government consumption shocks on the current account and the real exchange rate as well as the influence of various country characteristics on these effects a dataset of 18 industrial countries is used for the analysis panel var models are estimated for the groups of countries classified by country characteristics the primary empirical findings are as follows first positive government consumption shocks lead if anything to real exchange rate depreciation but the direction of the current account response varies across samples in particular positive government consumption shocks lead to real exchange rate depreciation under a floating exchange rate regime second international capital mobility has a significant impact on the effects of government consumption shocks the depreciation of the real exchange rate and the improvement of current account are larger in countries with low international capital mobility than those with high capital mobility third albeit less robust the depreciation of the real exchange rate and the improvement of the current account are larger in countries under more flexible exchange rate regimes than those under less flexible exchange rate regimes in addition the current account improves more in countries with high trade openness than those with low trade openness standard theories do not fully explain these empirical patterns thus these findings suggest a need for further theoretical development

twin sons of different mothers the long and the short of the twin deficits debate i introduction the relationship between the government budget deficit and the current account deficit has been a contentious subject in empirical macroeconomics for at least the past 20 yr papers have variously found a positive link no link and three recent pieces even find a negative link between the two there are however some things that almost all these studies have in common for example they ignore the possibility of structural breaks in the series when examining their time series properties most previous studies treat the variables under study as being integrated of order 1 which is to say as having a unit root this is a hard assumption to square with the fact that the variables are measured as fractions of gross domestic product gdp and have over the last half century at least shown no inclination toward typical unit root behavior by contrast in three recent pieces corsetti and muller 2006 kim and roubini 2008 muller 2006 the two series are simply treated as pure stationary processes without any pretesting which obviously conflicts with results from the traditional unit root tests in this article we show that both the budget deficit and the current account deficit are stationary around an occasionally shifting mean which is to say that they have structural breaks but are stationary after allowing for those breaks since it is well known that traditional unit root tests have little power when the underlying data contain structural breaks this explains the puzzling finding that the budget deficit and the current account deficit expressed as fractions of gdp test out as i 1 series in practice our findings also cast doubt on the validity of assuming the two series are purely stationary processes given our framework a simple test for the existence of a long run equilibrium relationship between budget and current account deficits is to compare the number and timing of their structural shifts we find that the two series are not closely related either in their number of breaks or in their timing of structural shifts we thus conclude that over the long run genetically the deficits are not twins another factor that existing studies have in common is their treatment of the error structure of the model as homoskedastic despite relatively clear visual evidence of volatility clustering conditional heteroskedasticity in least squares residuals when we consider the short run dynamics of the demeaned variables through a vector autoregression var analysis we show that the error covariance of this var model is significantly conditionally heteroskedastic and go on to specifically account for this phenomenon with a var generalized autoregressive conditional heteroskedasticity garch model we consider a trivariate model that also includes the real interest rate here we find a significant and sizeable positive short run effect of budget deficit innovations on the current account deficit in both the impulse response functions and the variance decompositions of the model our answer to the question of the paternity of the two deficits thus depends on the horizon studied each series has structural breaks that are largely independent of each other so they are not twins at all over the long run however once we allow for these secular shifts the short run dynamics reveal a very strong family resemblance indeed the rest of the article is organized as follows in section ii we review some of the existing empirical literature section iii discusses the time series properties of the data and presents our results about the long run evidence on the twin deficits question section iv sets out our var garch model and presents our results on short run twin deficits behavior section v is a brief conclusion ii an overview of the empirical literature the relationship between current account deficits and government budget deficits has been a subject of extensive study

current real business cycle theories and aggregate labor market fluctuations hours worked and the return to working are weakly correlated traditionally the ability to account for this fact has been a litmus test for macroeconomic models existing real business cycle models fail this test dramatically we modify prototypical real business cycle models by allowing government consumption shocks to influence labor market dynamics this modification can in principle bring the models into closer conformity with the data our empirical results indicate that it does

temporary and permanent government spending in an open economy some evidence for the united kingdom abstract this paper investigates the effects of government spending changes on a small open economy in an intertemporal substitution framework if agents internalize the government s budget constraint temporary and permanent spending have different implications for wealth and consequently different effects on output and the balance of trade estimation of these effects isolates the different channels through which government spending can influence economic activity main findings for the united kingdom are that government spending i crowds out private spending ii is directly productive and iii when rising permanently leads to a negative wealth effect which induces a large rise in work effort

the role of consumption substitutability in the international transmission of monetary shocks abstract this paper develops a general framework to analyze the impact of monetary shocks in an open economy focusing on the role of the degree of substitutability between goods produced in different countries we extend the contributions by obstfeld and rogoff obstfeld m rogoff k 1995 exchange rate dynamics redux journal of political economy 103 624 659 and corsetti and pesenti corsetti g pesenti p 1997 welfare and macroeconomic interdependence nber working paper 6307 to show that the welfare impact differs across countries when the degree of substitutability between goods produced in different countries is different from the degree of substitutability between goods produced in the same country a shock that would be beneficial in a closed economy can have an adverse beggar thyself effect in the country where it takes place or an adverse beggar thy neighbor effect on its neighbor

productivity shocks budget deficits and the current account abstract productivity shocks and budget deficits are considered to be two key determinants of the current account in order to assess formally the role of both factors in driving current account movements the present paper extends the standard intertemporal model of the current account to allow for non ricardian household behavior testable cross equation restrictions for the current account and investment are derived by drawing on the distinction between country specific and global innovations to productivity as well as to the government budget we test the restrictions of the model against time series data for 21 oecd countries and find evidence in support of the model

twin deficits squaring theory evidence and common sense in this paper we reconsider the twin deficit hypothesis that fiscal shocks generating budget deficits also worsen external trade both from a theoretical point of view and by analyzing data for australia canada the uk and the us first we assess the joint dynamics of budget and trade deficits along the business cycle uncovering a strikingly recurrent s shaped relation between the two the correlation is actually negative suggesting twin divergence this observation however cannot rule out the possibility that government spending expansions and or tax cuts may cause trade deficits as the overall correlation is likely to be dominated by cyclical factors second we reconsider the transmission of government spending in a standard two country two good model we find that openness and the persistence of fiscal shocks are major determinants of the magnitude or even sign of the response of the trade balance to fiscal shocks for a given persistence of the fiscal shock the closer an economy the larger the crowding out effect on investment the lower the deterioration of the trade balance third we take this insight to the data investigating the transmission of fiscal shocks in a var framework in the four countries in our sample our empirical findings tend to support our view in the us and australia which are relatively less open than canada and the uk and where government spending shocks are less persistent we find that the external impact of fiscal policy is rather limited instead private investment responds substantially the reverse is true for canada and the uk these findings confirm and put into perspective earlier results whereas fiscal expansions in the us are found to have on average a negligible effect on the country s trade balance however we emphasize that these results are consistent with a call for a us fiscal retrenchment to address global imbalances the impact of budget cuts on the us external trade is muted by their positive effect on domestic investment strengthening the us ability to generate resources against future interest and debt repayment

indivisible labor lotteries and equilibrium abstract this paper considers an economy where labor is indivisible and agents are identical although the discontinuity in labor supply at the individual level disappears as a result of aggregation it is shown that indivisible labor has strong consequences for the aggregate bahavior of the economy it is also shown that optimal allocations involve lotteries over employment and consumption

tax and spending shocks in the open economy are the deficits twins abstract we present evidence on the open economy consequences of us fiscal policy shocks identified through proxy instrumental variables tax shocks and government spending shocks that raise the government budget deficit lead to persistent current account deficits in particular the negative response of the current account to exogenous tax reductions through a surge in the demand for imports is among the strongest and most precisely estimated effects moreover we find that the reduction of the current account is amplified when the tax reduction is due to lower personal income taxes and when the government increases its consumption expenditures historically a much larger share of current account dynamics has been due to tax shocks than to government spending shocks

useful government spending direct crowding out and fiscal policy interdependence this paper introduces perfect substitutability between private and public consumption in a dynamic open economy with imperfect competition and nominal rigidities this implies a direct crowding out effect that generalising to the two country case some well known properties of a closed economy tends to reduce consumption following both domestic and foreign expansions a less expected result is that sub stitutability has a positive effect on the short run output spillover we also show that if we modify the model to allow for home bias in government spending temporary fiscal expansions display a quasi neutrality property

us trade balance dynamics the role of fiscal policy and productivity shocks and of financial market linkages abstract this paper examines whether domestic and foreign productivity and fiscal policy changes can account for the wide swings in us net exports during the period 1975 1991 a two country real business cycle model is used for that purpose the model is simulated using data on productivity government purchases and taxes for the g7 countries a version of the model with incomplete asset markets in which only bonds can be used for international capital flows tracks the us trade balance fairly closely provided permanent country specific productivity shifts are assumed the simulations suggest that us productivity changes were the main source of fluctuations in us net exports

the impact of investors risk aversion on the performances of capacity remuneration mechanisms abstract this paper analyses the impact of risk aversion on the performances of capacity remuneration mechanisms with investors facing an uncertain peak load three market designs are studied for this purpose a competitive energy only market a capacity market and a strategic reserve mechanism a simulation model based on system dynamics is developed in order to represent investment decisions and analyse the behaviour of each market design risk aversion is modelled through the computation of conditional value at risk the results are discussed in terms of impact on the reliability ability to limit shortages and cost total generation costs of the studied market designs when comparing the three market designs the capacity market seems to be the least affected by the introduction of risk aversion both in terms of cost and reliability this result suggests that implementing a capacity market is preferable in order to deal with the adverse effects of risk aversion given the simulations and parameters that were used

welfare and macroeconomic interdependence we develop a baseline model of monetary and fiscal transmission in interdependent economies the welfare effects of expansionary policies are related to monopolistic supply in production and monopoly power of a country in trade an unanticipated exchange rate depreciation can be beggar thyself rather than beggar thy neighbor as gains in domestic output are offset by deteriorating terms of trade smaller and more open economies are more prone to suffer from inflationary shocks larger economies benefit from moderate demand led expansions but may be worse off if policy makers attempt to close the output gap fiscal shocks are generally beggar thy neighbor in the long run in the short run they raise domestic demand at given terms of trade thus reducing the welfare benefits from monetary expansions analytical tractability makes our model uniquely suitable as a starting point to approach the recent new open economy macroeconomic literature

the macroeconomic effects of distortionary taxation abstract prescott 1986 estimates that technology shocks account for 75 of the fluctuations in the postwar u s economy this paper reestimates the contribution of technological change for a standard business cycle model that includes a public sector and fiscal disturbances i find that a significant fraction of the variance of aggregate consumption investment output capital stock and hours of work can be explained by disturbances in labor and capital tax rates and government consumption i also use the model to quantify the welfare costs of capital and labor taxation for both the time series and welfare calculations maximum likelihood estimates of taste technology and policy parameters are used

risk return incentives in liberalised electricity markets we employ monte carlo analysis to determine the distribution of returns for various electricity generation technologies costs and revenues for each technology are calculated by means of a unit commitment and economic dispatch algorithm at hourly resolution this represents a considerable contribution to the literature as costs and revenues are determined endogenously which in turn allows the returns of midmerit and peaking plant to be examined market entry is determined on the basis of a heuristic while market exit is according to a predetermined retirement schedule the results show that ccgt is the investment technology of choice for baseload only portfolios while ocgt proves optimal when all technologies are considered the high capital costs of baseload generation reduce incentives to invest the methodology can be expanded to consider random outages revenues from scarcity prices capacity markets and ancillary service payments

dynamics of the trade balance and the terms of trade the j curve the authors provide a theoretical interpretation of two features of international data the countercyclical movements in net exports and the tendency for the trade balance to be negatively correlated with current and future movements in terms of trade but positively correlated with past movements they document the same properties in a two country stochastic growth model in which trade fluctuations reflect in large part the dynamics of capital formation the authors find that their general equilibrium perspective is essential the relation between the trade balance and the terms of trade depends critically on the source of fluctuations copyright 1994 by american economic association

the robot the party animal and the philosopher an evolutionary perspective on deliberation and preference this paper examines the evolutionary fitness of a variety of ways of reaching decisions in early hunter gatherer societies in order to derive insights about how economists should view modern consumers it challenges conclusions reached by mainstream economists robson rayo and becker about why hunter gatherers needed sensory rewards and about the kinds of preference systems that would have conferred evolutionary fitness it argues that evolution favours those with a variety of ways of reaching decisions programmed deliberative intuitive and go with the flow and that the prospect of sensory rewards serves an evolutionary role by diverting people from thinking too much about what they are doing in situations in which deliberation might interfere with survival or reproduction the evolutionary role of a reluctance or failure to make trade offs is also considered along with the benefits of developing a relatively fixed identity rather than being all things to all men

mode locking and international business cycle transmission abstract we investigate international business cycle synchronization business cycles in many countries have a tendency to synchronize with one another in what appears to be a world business cycle yet researchers find that trade and capital linkages are not strong enough for one country to drive business cycles in another country how is this world business cycle formed this study suggests that the world business cycle results from a mode locking phenomenon a nonlinear process by which weak coupling between oscillating systems tends to synchronize oscillations in the systems simulations and econometric analyses are performed to attempt to verify this hypothesis

sticky goods prices flexible asset prices monopolistic competition and monetary policy a monetary general equilibrium asset pricing model with sticky goods prices is developed goods prices are set by monopolistically competitive firms that maximize stock market value equilibria with underutilization of resources excess capacity in some states result in contrast to previous monetary asset pricing models the degree of competition affects capacity utilization monetary policy can affect output and resource utilization in addition to real asset prices depending upon the amount of information available to the monetary authority

fiscal policy and external adjustment new evidence abstract relatively little empirical evidence exists about countries external adjustment to changes in fiscal policy and in particular to changes in taxes this paper addresses this question by measuring the effects of tax and government spending shocks on the current account and the real exchange rate in a sample of four industrialized countries our analysis is based on a structural vector autoregression in which the interaction of fiscal variables and macroeconomic aggregates is left unrestricted identification is instead achieved by exploiting the conditional heteroscedasticity of the structural disturbances three main findings emerge i the data provide little support for the twin deficit hypothesis ii the estimated effects of unexpected tax cuts are generally inconsistent with the predictions of standard economic models except for the us and iii the puzzling real depreciation triggered by an expansionary public spending shock is substantially larger in magnitude than predicted by traditional identification approaches

cross border electricity market effects due to price caps in an emission trading system an agent based approach the recent low co2 prices in the european union emission trading scheme eu ets have triggered a discussion whether the eu ets needs to be adjusted we study the effects of co2 price floors and a price ceiling on the dynamic investment pathway of two interlinked electricity markets loosely based on great britain which already has introduced a price floor and on central western europe using an agent based electricity market simulation with endogenous investment and a co2 market including banking we analyse the cross border effects of national policies as well as system wide policy options a common moderate co2 auction reserve price results in a more continuous decarbonisation pathway this reduces co2 price volatility and the occurrence of carbon shortage price periods as well as the average cost to consumers a price ceiling can shield consumers from extreme price shocks these price restrictions do not cause a large risk of an overall emissions overshoot in the long run a national price floor lowers the cost to consumers in the other zone the larger the zone with the price floor the stronger the effect price floors that are too high lead to inefficiencies in investment choices and to higher consumer costs

estimation and control of an optimization based model with sticky prices and wages abstract this paper provides estimates of an optimization based equilibrium model with sticky prices and wages the estimated model is used to analyse the welfare properties of various interest rate rules for conducting monetary policy an important feature of this model is that it involves a tradeoff between the variances of price and wage inflation and the output gap this tradeoff implies that it is desirable for the monetary authority to respond to wage inflation in addition to price inflation output and past interest rates when setting the current interest rate the issue whether wages and prices can be indexed to steady state inflation has important implications both for the characterization of optimal interest rate rules and interest rate volatility in particular optimal policy in the presence of indexation induces implausibly high steady state inflation

the market for preferences learning processes are widely held to be the mechanism by which boundedly rational agents adapt to environmental changes we argue that this same outcome might also be achieved by a different mechanism namely specialisation and the division of knowledge which we here extend to the consumer side of the economy we distinguish between high level preferences and low level preferences as nested systems of rules used to solve particular choice problems we argue that agents while sovereign in high level preferences may often find it expedient to acquire in a pseudo market the low level preferences in order to make good choices when purchasing complex commodities about which they have little or no experience a market for preferences arises when environmental complexity overwhelms learning possibilities and leads agents to make use of other people s specialised knowledge and decision rules

the role of saving and investment in exchange rate determination under alternative monetary mechanisms abstract we argue that the demand for national currencies depends on existing payment arrangements for imports and exports therefore exchange rate movements depend on these arrangement as a result the relationship between exchange rate movements and various macroeconomic aggregates like saving and investment depend on what we call the monetary mechanism these points are explicitly demonstrated by studying two extreme monetary mechanisms one in which all payments are done with the seller s currency and one in which all payments are done with the buyer s currency

the importance of composition of fiscal policy evidence from different exchange rate regimes abstract we study the macroeconomic effects of fiscal policies in an open economy we emphasize two transmission mechanisms the cost channel by which wage government spending and labor taxes raise the real wage firms must pay and the exchange rate channel by which the nominal exchange rate shifts induced by fiscal policy have real effects if some prices and wages are sticky the latter channel implies that changes in wage government spending or in labor taxation should have different effects under flexible than under fixed exchange rates in a 1964 93 panel of oecd countries we find significant evidence for both channels moreover we find that the real product wage and profitability are more responsive than quantities employment and output to fiscal policy innovations

exchange rates and traded goods prices abstract this paper presents a partial equilibrium model of the determination of domestic and export prices by a monopolistic competitive firm the model stresses the role of exchange rate uncertainty and expectations the most important result of the analysis is that the stochastic properties of deviations from the law of one price are crucially affected by the currency of denomination of export prices using data on domestic and dollar export prices of japanese goods i find that deviations from the law of one price are due to exchange rate surprises but also to price staggering and ex ante price discrimination

capital controls and fiscal policy in the world economy an intertemporal utility maximization framework is employed to model a world economy with capital controls the effects of fiscal policy in such an environment are examined several results emerge concerning the international transmission of fiscal policy under capital controls and the nature of comovements in macro economic aggregates such as output employment consumption and investment some of the paper s other results concern the implications of capital controls for ricardian equivalence the role of financing decisions in the international transmission process under capital controls and the effect of capital controls on the magnitude of fiscal induced fluctuations throughout the world economy contr6les des mouvements de capitaux et politique fiscale dans l conomie mondiale les auteurs utilisent une approche par la maximisation intertemporelle de l utilite pour modeliser une economie mondiale dans laquelle des controles sur les mouvements de capitaux existent ils examinent les effets de la politique fiscale dans un tel contexte on tire de ces analyses plusieurs resultats quant i la transmission internationale des effets de la politique fiscale et quant aux mouvements lies de certains agregats economiques comme les niveaux de production d emploi de consommation et d investissement certains autres resultats de cette analyse ont trait aux implications des controles des mouvements de capitaux sur l1 quivalence ricardienne au role des decisions de financement dans le processus international de transmission quand il y a controle des mouvements de capitaux et aux effets des controles sur les mouvements de capitaux sur la magnitude des fluctuations induites a travers l economie mondiale par la politique fiscale helpful comments from two anonymous referees are gratefully acknowledged discussion in workshops held at ucla duke university iowa state university queen s university vanderbilt university vpi and the university of western ontario has also been useful canadian journal of economics revue canadienine d economique xviii no 4 november novembre 1985 printed in canada imprime au canada 0008 4085 85 743 65 1 50 canadian economics association this content downloaded from 207 46 13 129 on mon 27 jun 2016 05 25 03 utc all use subject to http about jstor org terms 744 jeremy greenwood and kent p kimbrough

understanding the dynamic effects of government spending on foreign trade abstract using vector autoregressions on u s time series the present paper documents the effects of fiscal policy on foreign trade an increase in government spending significantly depreciates the nominal exchange rate appreciates the terms of trade and increases net exports exposed to the same spending shock a new keynesian general equilibrium model is shown to match qualitatively the response of relative prices the response of net exports in contrast depends on the intra and intertemporal elasticities of substitution and the degree of home bias in private spending an accommodating monetary policy dampens but does not alter the response of net exports

the effects of government purchases shocks review and estimates for the eu in this article we review the theoretical consequences of government purchases shocks for both closed and open economies followed by a discussion of the empirical literature next we provide our own estimates for the eu countries we find that an increase in government purchases raises output consumption and investment and reduces the trade balance however the stimulating effect is weaker and the trade balance reduction is larger for the more open eu economies consistent with larger leakage effects further we show that government purchases shocks in large eu economies have non negligible consequences for economic activity in the main trading partners

global effects of national stabilization policies under fixed and floating exchange rates this paper deals with international effects of two types of stabilization policies monetary expansion directed towards the demand side and a reduction in payroll taxes directed towards the supply side the analysis focuses on employment relative prices and welfare issues it rests on a simple intertemporal general equilibrium model of two countries that includes a specific micro theory of money under floating exchange rates a country s employment is insulated from both policies abroad but its consumption generally changes under fixed exchange rates no such insulation prevails while monetary expansion is generally expansionary reduced payroll taxes constitute a beggar thy neighbor policy in both systems the welfare of a country may decrease although its employment increases an immiserizing expansion may occur

has fiscal policy helped stabilize the postwar u s economy abstract in this paper i consider whether postwar fiscal policy has helped stabilize the u s economy i do this by adding to the stochastic growth model fiscal policy feedback rules estimated from postwar data these rules allow fiscal policies to respond to current and lagged output and labor hours i use the estimated policy rules to see if postwar fiscal policy reduces output volatility and or lengthens expansions and shortens recessions i find that fiscal policy in general provides little stability on either count i also find that the endogenous feedback links by themselves can provide some stabilization

fiscal policy in general equilibrium this paper studies four classic fiscal policy experiments within a quantitatively restricted neoclassical model the authors main findings are as follows 1 permanent changes in government purchases can lead to short run and long run output multipliers that exceed one 2 permanent changes in government purchases induce larger effects than temporary changes 3 the financing decision is quantitatively more important than the resource cost of changes in government purchases and 4 public investment has dramatic effects on private output and investment these findings stem from important dynamic interactions of capital and labor absent in earlier equilibrium analyses of fiscal policy copyright 1993 by american economic association

fiscal policy in the new neoclassical synthesis we analytically derive the cyclical effects of fiscal policy shocks in a new neoclassical synthesis model price stickiness has the consequence that a rise in government demand affects labor demand while at the same time the usual wealth effect boosts labor supply the strength of the demand effect depends on the response of the real interest rate governed by the monetary policy regime when the central bank controls money growth fiscal expansions are deflationary and might even be contractionary whereas output wages and inflation can increase when the rise in the real interest rate is dampened by an interest rate rule however price stickiness alone is not sufficient to explain a rise in consumption as predicted by keynesian theory

the effects of government spending on real exchange rates evidence from military spending panel data abstract using panel data on military spending for 125 countries we document new facts about the effects of changes in government purchases on the real exchange rate consumption and current accounts in both advanced and developing countries while an increase in government purchases causes real exchange rates to appreciate and increases consumption significantly in developing countries it causes real exchange rates to depreciate and decreases consumption in advanced countries the current account decreases in both groups of countries these findings are not consistent with standard international business cycle models we discuss potential sources of the differences between advanced and developing countries in the responses to spending shocks

excess capacity monopolistic competition and international transmission of monetary disturbances analyzes the excess capacity monopolistic competition and international transmission of monetary policy disturbances in the united states sheds light on the international impact of monetary policy emphasis on the spillover effects of monetary disturbances similarity of framework used with open economy macroeconomics

technology shocks and employment recent empirical work has suggested that in response to a positive technology shock employment shows a persistent decline we show that the standard open economy flexible price model can generate a negative response of employment to a positive technology shock and can also match the negative conditional correlation between productivity and employment quite well if trade elasticities are low while the model also has good overall properties it fails to generate sufficient procyclicality in employment this finding indicates that the rbc model faces a tension between accounting for the negative response of employment to technology shocks and simultaneously maintaining that technology shocks are the major source of business cycle fluctuations

fiscal shocks and their consequences this paper investigates the response of hours worked and real wages to fiscal policy shocks in the post world war ii us we identify these shocks with exogenous changes in military purchases and argue that they lead to a persistent increase in government purchases and tax rates on capital and labor income and a persistent rise in aggregate hours worked as well as declines in real wages the shocks are also associated with short lived rises in aggregate investment and small movements in private consumption we describe and implement a methodology for assessing whether standard neoclassical models can account for the consequences of a fiscal policy shock simple versions of the neoclassical model can account for the qualitative effects of a fiscal shock once we allow for habit formation and investment adjustment costs the model can also account reasonably well for the quantitative effects of a fiscal shock

twin deficit or twin divergence fiscal policy current account and real exchange rate in the u s abstract in spite of concerns about twin deficits fiscal and the current account deficits for the united states economy empirical evidence suggests that twin divergence is a more usual feature of the historical data i e when fiscal accounts worsen the current account improves and vice versa this paper empirically studies the effects of fiscal policy government budget deficit shocks on the current account and the real exchange rate during the flexible exchange rate regime period based on var vector auto regression models we identified exogenous fiscal policy shocks after controlling for business cycle effects on fiscal balances in contrast to the predictions of most theoretical models the u s results suggest that an expansionary fiscal policy shock or a government budget deficit shock improve the current account and depreciate the real exchange rate increases in private savings and declines in investment contribute to the current account improvement while a nominal exchange rate depreciation as opposed to a relative price level change is mainly responsible for the real exchange rate depreciation the twin divergence of fiscal balances and current account balances is also explained by the prevalence of output shocks i e output shocks more than fiscal shocks appear to drive the co movements of the current account and the fiscal balance

evolution and human nature from an economic perspective on individual decision making human beings have three key characteristics preferences beliefs and rationality beliefs are the probabilities with which people think various outcomes will occur conditional on information that might be available preferences are the rankings over the set of gambles that are based on such beliefs over the outcomes rationality is the extent to which people succeed in choosing optimal actions in the light of their beliefs and preferences and the extent to which their beliefs are appropriately modified by their information economists typically impose only rather weak assumptions on preferences for example preferences are taken to be transitive and sometimes less explicitly exogenous and unchanging stronger assumptions are typically imposed on preferences in specific contexts however for example preferences over time might be represented by an additively separable function with constant rate of discount despite widespread recognition that this case is a special one further attitudes to risk are often represented by the expected utility theorem which rests on assumptions that are strong if also appealing the assumptions made on rationality in particular are usually very strong that is rationality in economic models usually entails the exact optimization of preferences and modification of beliefs in accordance with bayes theorem the economist s basic picture of preferences beliefs and rationality has been subject to challenges from a growing number of empirical anomalies the proposed explanations of these anomalies involve relaxing the assumptions that economists make on these preferences beliefs or rationality for example preferences

an analysis of a forward capacity market with long term contracts we analyze the effectiveness of a forward capacity market fcm with long term contracts in an electricity market in the presence of a growing share of renewable energy an agent based model is used for this analysis capacity markets can compensate for the deteriorating incentive to invest in controllable power plants when the share of variable renewable energy sources grows but may create volatile prices themselves capacity markets with long term contracts have been developed e g in the uk to stabilize capacity prices in our analysis a fcm is effective in providing the required adequacy level and leads to lower cost to consumers and more stable capacity prices as compared to a yearly capacity market in case of a demand shock a fcm may develop an investment cycle but it still maintains security of supply its main effect on the power plant portfolio is more investment in peak plant

the macroeconomic effects of war finance in the united states world war ii and the korean war during world war ii government expenditures were financed primarily by issuing debt during the korean war expenditures were financed almost exclusively by higher taxes reflecting president truman s preference for balanced budgets this paper evaluates quantitatively the economic effects of the different policies used to finance these two wars counterfactual experiments are used to explore the implications of financing world war ii like the korean war and financing the korean war like world war ii the author finds that using a korean war policy during world war ii would have resulted in much lower output and welfare relative to the actual policy copyright 1997 by american economic association

the effects of discretionary fiscal policy on macroeconomic aggregates a reappraisal fiscal stimuli to recover a cascade of academic and layman articles debate the effectiveness of fiscal policy in stimulating the economy backed up by different economic models and empirical support this essay surveys the theoretical predictions and recent empirical vector autoregression var evidence on the short run effects of discretionary fiscal policy on macroeconomic aggregates

habit formation and fiscal transmission in open economies in this paper we analyze the ability of an open economy version of the neoclassical model to account for the time series evidence on fiscal policy transmission revisiting the evidence we find that i government spending raises output while inducing a simultaneous decline of investment and the current account and ii the responses of output and investment are more muted in more open economies while current account deficits tend to be larger turning to the model we explore the role of habit formation for fiscal policy transmission specifically we show that the model can account for the evidence if consumption behavior is characterized by habit formation and the terms of trade adjust endogenously

channels of international policy transmission abstract four channels of international budgetary and monetary policy transmission are analysed within the context of nominal wage sluggishness the first is based on capital gains on holdings of foreign assets spill over effects arising through the second and third channels depend on whether home and foreign goods are gross substitutes or gross complements and on whether the elasticity of intertemporal substitution is less or greater than one the final channel assumes finite lifetimes and no bequest motive it departs from debt neutrality in order to give a non trivial role to wealth effects and current account dynamics

long term assessment of power capacity incentives by modeling generation investment dynamics under irreversibility and uncertainty abstract in actual energy only markets the high volatility of power prices affects the expected returns of generators when dealing with irreversibility under uncertainty deferring decisions to commit in new power plants waiting for better information is therefore a rational approach theoretical and empirical evidence suggests that such investment pattern determines the occurrence of construction cycles which strongly compromise supply security in order to supplement generators revenues several remuneration mechanisms have been devised over past years along this line this work addresses the long run dynamics of capacity adequacy and market efficiency with both a price based and a quantity based capacity remuneration policy for that purpose a recently developed stochastic simulation model is used as a benchmark hence the optimal postponement of generation investment decisions is integrated into a long run power market model by formulating the decision making problem in the framework of real options analysis results suggest that policymakers may exchange supply security effectiveness for energy prices to be paid by consumers efficiency when designing and implementing capacity remuneration mechanisms by doing so this article contributes to the ongoing debate regarding the design of incentive policies and efficient power markets by considering the microeconomics of investors decision making under irreversibility and uncertainty
