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

a reevaluation of the macroeconomic effects of positive trend inflation abstract to date most of the papers which have examined the effects of trend inflation on the properties of new keynesian model were based on relatively simple sticky prices dsge models and whose realism was sometimes questionable in this paper we re evaluate the macroeconomic effects of non zero trend inflation building on the model of ascari 2004 as one of the most cited papers in the literature on the effects of trend inflation we show that the omission of some important theoretical ingredients significantly distorts the results obtained to date we propose a refinement of this model by introducing two theoretical important ingredients namely investment adjustment costs and a roundabout production structure once we add these features to make the model more realistic as commonly for medium scale models we find that the standard new keynesian model without real frictions overestimates the short term macroeconomic effects of a positive trend inflation rate and underestimates those of the long term

the impact of fiscal policy on profits i introduction a large number of policy making decisions rely on the key issue of the impact of fiscal policy on the economy therefore it is not surprising that the effect of fiscal policy on macroeconomic aggregates has been extensively studied in the empirical literature 1 several authors starting with blanchard and perotti 2002 have attempted to estimate the effect of government spending shocks on output and other variables in the context of structural var models see perotti 2008 for a survey this interest has been renewed since the 2008 2009 recession given the unprecedented size of fiscal packages worldwide barro and redlick 2009 hall 2009 an important part of this literature focuses on the theoretical and empirical investigation of the fiscal policy transmission channels theories of fiscal policy transmission differ in their implications regarding the response of different macroeconomic variables to government spending shocks for example the neoclassical model predicts a negative impact of government spending on real wages and consumption while this prediction is challenged by new keynesian models to that end an important branch of empirical literature on fiscal multipliers has investigated the transmission channels of fiscal policy by looking mainly at the response of private consumption and real wages 2 this paper deals with an important but relatively under investigated channel of fiscal policy transmission which is the effect of fiscal policy on profits as pointed out by hall 2009 the impact of fiscal shocks on the markup of price over marginal cost is important for understanding the functioning of the fiscal multiplier in the purely neoclassical general equilibrium model a rise in government spending produces a negative wealth effect the labor supply curve shifts outward and real wages and consumption fall this implies that the output multiplier will be well below unity a keynesian type fiscal multiplier implying a large positive output effect and positive responses of private consumption and real wages to increased government spending relies on a negative response of the markup of price over marginal cost to an increase in economic activity the intuition is that a decrease in the price marginal cost markup in response to higher government spending allows a rise in wages or at least a smaller reduction in wages compared with the case when the markup is constant a rise in wages would then imply that households will substitute away from leisure and into consumption therefore if the markup is countercyclical conditional on government spending shocks sizeable output multipliers of fiscal spending are consistent with existing empirical evidence that fiscal shocks are not related to strong decreases in real wages or consumption blanchard and perotti 2002 fatas and mihov 2001 gall david lopez salid and valles 2007 perotti 2005 2008 in general a new keynesian model with sticky prices implies a countercyclical markup ratio as input prices rise in a boom while output prices stay constant however for understanding the fiscal policy transmission the key factor is markup and not price stickiness itself as a countercyclical markup could also be implied by models with flexible prices when the desired markup changes in response to a shock 3 a model which assigns a central role to markups for fiscal policy transmission has been presented by ravn schmitt grohe and uribe 2007 assuming that demand has a price inelastic component that is a function of deep habits a government spending shock that leads to a positive output response increases the share of the price elastic component of demand causing a rise in the overall demand elasticity and a corresponding decline in the optimal markup 4 thus for a sufficient decline in the markup the resulting rise in wages induces households to substitute away from leisure and into consumption thereby more than offsetting the negative wealth effect of government spending predicted by the neoclassical model

asset returns and business cycles in models with investment adjustment costs we show that adjustment cost models with labor supply can explain both asset returns and business cycle facts when adjustment costs penalize the changes of investment this conclusion stands in contrast to results obtained in the literature with adjustment costs that penalize the changes of capital

supply storage and service reliability decisions by gas distribution utilities a chance constrained approach this paper explores the trade offs among purchases storage and service reliability decisions faced by natural gas distribution utilities the short term demand for natural gas fluctuates because of the weather to encourage load leveling the pipeline transmission companies that supply the utilities use a demand contract that charges utilities based on their peak day needs and often charge for a minimum daily purchase requirement whether that purchase is made or not the policy variables available to the utility include increasing its storage capacity and providing interruptible service to some customers thereby lowering reliability of service there are also technological constraints on the maximum storage gas flows to explore these trade offs a chance constrained cost minimization problem is formulated two decision rules for gas purchases and storage operation are examined in these rules an initial decision is made at the beginning of each month about either the level of purchases or the level of

real business cycle models past present and future in this paper i review the contribution of real business cycles models to our understanding of economic fluctuations and discuss open issues in business cycle research this abstract was borrowed from another version of this item

a large scale linear complementarity model of the north american natural gas market abstract the north american natural gas market has seen significant changes recently due to deregulation and restructuring for example third party marketers can contract for transportation and purchase of gas to sell to end users while the intent was a more competitive market the potential for market power exists we analyze this market using a linear complementarity equilibrium model including producers storage and peak gas operators third party marketers and four end use sectors the marketers are depicted as nash cournot players determining supply to meet end use consumption all other players are in perfect competition results based on national petroleum council scenarios are presented

targeted transfers and the fiscal response to the great recession abstract between 2007 and 2009 government expenditures increased rapidly across the oecd countries while economic research on the impact of government purchases has flourished in the data most of the increase in expenditures was in government transfers after documenting this fact we argue that future research should focus on the positive impact of transfers towards this we present a model in which there is no representative agent and ricardian equivalence does not hold because of uncertainty imperfect credit markets and nominal rigidities targeted lump sum transfers are expansionary both because of a neoclassical wealth effect and because of a keynesian aggregate demand effect

a time series analysis of representative agent models of consumption andleisure choice under uncertainty this paper investigates empirically a model of aggregate consumption and leisure decisions in which utility from goods and leisure is nontime separable the nonseparability of preferences accommodates intertemporal substitution or complementarity of leisure and thereby affects the comovements in aggregate compensation and hours worked these cross relations are examined empirically using postwar monthly u s data on quantities real wages and the real return on the one month treasury bill the estimated values of the parameters governing preferences differ significantly from the values assumed in several studies of real business models several possible explanations of these discrepancies are discussed

a marginal cost pricing model for gas distribution utilities we develop a natural gas distribution utility pricing model that includes optimization of supply mix and capacity expansion financial analysis of revenue requirements and design of either average cost or marginal cost based rates and apply it using data from the east ohio gas company the results clearly point to the superiority of marginal cost over average cost pricing policies in terms of lesser capital requirements better capacity utilization and higher end use economic efficiency

pre announcement and timing the effects of a government expenditure shock abstract an econometric strategy to identify a pre announced fiscal policy shock is proposed i show that the reduced form innovations can be recovered by estimating a vector moving average model using the kalman filter the structural effects are identified exploiting the shock s pre announced nature which leads to potentially different signs of the responses of some endogenous variables during the announcement and after the realization of the shock i illustrate my strategy by identifying a pre announced shock to government consumption expenditures i find that the response of private consumption is significantly negative on impact rises and becomes significantly positive two quarters after the realization of the policy shock

fiscal shocks and real exchange rate dynamics some evidence for latin america this paper analyses the effects of fiscal shocks using a two country macroeconomic model for output labour input government spending and relative prices which provides the orthogonality restrictions for obtaining the structural shocks dynamic simulation techniques are then applied in particular to shed light on the possible effects of fiscal imbalances on the real exchange rate in the case of six latin american countries using quarterly data over the period 1980 2006 we find that in a majority of cases fiscal shocks are the main driving force of real exchange rate fluctuations

fiscal expansions unemployment and labor force participation theory and evidence structural vars indicate that for many oecd countries labor force participation employment and the unemployment rate significantly increase following increases in government expenditures under a variety of specifications and identification schemes fiscal expansions also tend to increase real wages existing models have difficulties in generating such responses we show that the empirical regularities can be reproduced with two additions into a standard new keynesian model with matching frictions a a labor force participation choice and b workers heterogeneity

does neoclassical theory account for the effects of big fiscal shocks evidence from world war ii much debate surrounds the usefulness of the neoclassical growth model for assessing the macroeconomic impact of fiscal shocks we test the theory using data from world war ii which is by far the largest fiscal shock in the history of the united states we take observed changes in fiscal policy during the war as inputs into a parameterized dynamic general equilibrium model and compare the values of all variables in the model to the actual values of these variables in the data our main finding is that the theory quantitatively accounts for macroeconomic activity during this big fiscal shock

the fiscal multiplier in a liquidity constrained new keynesian economy we study the effects of fiscal policy on the macroeconomy using a liquidity constrained new keynesian model in which government bonds are liquid and private financial assets are only partially liquid we find that the fiscal multipliers in this economic environment are large enough for fiscal policy to be highly effective in this model a bond financed fiscal expansion can stimulate output because higher public borrowing improves liquidity by increasing the proportion of liquid assets in private sector wealth

household debt and fiscal multipliers we study the size of government spending multipliers in a general equilibrium model with search and matching frictions in which we allow for different levels of household indebtedness the main results are a the presence of impatient households and private debt helps to generate government spending multipliers greater than 1 b as financial conditions worsen the size of the government spending multiplier falls c conversely employment vacancies and unemployment multipliers are larger in a credit crunch d the model explains the observed pattern of responses of labour market variables housing prices and private debt to a fiscal shock reasonably well

marginal tax rates and income new time series evidence this paper estimates the dynamic effects of marginal tax rate changes on income reported on tax returns in the united states over the 1950 2010 period after isolating exogenous variation in average marginal tax rates in structural vector autoregressions using a narrative identification approach i find large positive effects of tax cuts in the top 1 of the income distribution in contrast to earlier findings based on tax return data i also find large effects in other income percentile brackets a hypothetical tax reform cutting marginal rates only for the top 1 leads to sizeable increases in top 1 incomes and has a positive effect on real gdp there are also spillover effects to incomes outside of the top 1 but top marginal rate cuts lead to greater inequality in pre tax incomes

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

keynesian government spending multipliers and spillovers in the euro area the global financial crisis has led to a renewed interest in discretionary fiscal stimulus advocates of discretionary measures emphasize that government spending can stimulate additional private spending the keynesian multiplier effect thus we investigate whether the spending package announced by euro area governments for 2009 and 2010 is likely to boost gdp by more than one for one because of modelling uncertainty it is essential that such policy evaluations be robust to alternative modelling assumptions and parameterizations we use five different empirical macroeconomic models with keynesian features such as price and wage rigidities to evaluate the impact of the fiscal stimulus four of them suggest that the planned increase in government spending will reduce private consumption and investment significantly only a model that largely ignores the forward looking behavioural response of consumers and firms implies crowding in of private spending we review a range of issues that may play a role in the recession of 2008 2009 implementation lags are found to reinforce crowding out and may even cause an initial contraction zero bound effects may lead the central bank to abstain from interest rate hikes and increase the gdp impact of government spending crowding in however requires an immediate anticipation of at least two years at the zero bound using a multi country model we find that spillovers between euro area countries are negligible or even negative because direct demand effects are offset by the indirect effect of a euro appreciation new keynesian dynamic stochastic general equilibrium dsge models provide a strong case for government savings packages announced with sufficient lead time spending cuts induce a significant short run stimulus and crowding in of private spending tobias cwik and volker wieland

sticky price models of the business cycle can the contract multiplier solve the persistence problem we construct a quantitative equilibrium model with firms setting prices in a staggered fashion and use it to ask whether monetary shocks can generate business cycle fluctuations these fluctuations include persistent movements in output along with the other defining features of business cycles like volatile investment and smooth consumption we assume that prices are exogenously sticky for a short time persistent output fluctuations require endogenous price stickiness in the sense that firms choose not to change prices much when they can do so we find that for a wide range of parameter values the amount of endogenous stickiness is small thus we find that in a standard quantitative model staggered price setting alone does not generate business cycle fluctuations

a mixed complementarity based equilibrium model of natural gas markets we present a new multiseasonal multiyear natural gas market equilibrium model based on the concept of a competitive equilibrium involving the market participants producers storage reservoir operators peak gas operators pipeline operators marketers and consumers the first three classes are depicted as price takers consistent with perfect competition the pipeline operations are described with regulated tariffs but also involve congestion pricing as a mechanism to allocate scarce pipeline capacity the marketers are price takers in all markets except in sales to consumers in which they compete as nash cournot players finally consumers are described by demand curves for each of the four sectors residential commercial industrial and electric power we show that the equilibrium model is an instance of a mixed nonlinear complementarity problem ncp and provide sufficient detail not generally seen in previous complementarity models of natural gas the ncp formulation is derived from considering the karush kuhn tucker optimality conditions of the optimization problems faced by these participants under mild conditions we show that this ncp has a solution and under additional reasonable conditions we show that the market prices are unique we also validate the model on a representative sample network with nine market participants and three seasons using four scenarios

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

from great depression to great credit crisis similarities differences and lessons the great depression of the 1930s and the great credit crisis of the 2000s had similar causes but elicited strikingly different policy responses while it remains too early to assess the effectiveness of current policy it is possible to analyse monetary and fiscal responses in the 1930s as a natural experiment or counterfactual capable of shedding light on the impact of current policies we employ vector autoregressions instrumental variables and qualitative evidence for 27 countries in the period 1925 39 the results suggest that monetary and fiscal stimulus was effective that where it did not make a difference it was not tried they shed light on the debate over fiscal multipliers in episodes of financial crisis they are consistent with multipliers at the higher end of those estimated in the recent literature and with the argument that the impact of fiscal stimulus will be greater when banking systems are dysfunctional and monetary policy is constrained by the zero bound miguel almunia agustin benetrix barry eichengreen kevin h o rourke and gisela rua

technological change in u s jet fighter aircraft this paper quantitatively measures technological change in u s jet fighter aircraft from 1944 to the present day using the hedonic pricing approach the technical and performance characteristics of jet fighters have changed dramatically between the time they were first developed at the beginning of the 1940s and the present parallel to this technological change there has been a sharp escalation in costs regarding the new generations of jet fighter aircraft we estimate a measure of price for the performance and technical characteristics of these aircraft embodied technological change in jet fighter airframes is measured using quality adjusted prices although the flyaway cost of jet fighter aircraft has soared on average by about 12 63 per year the quality adjusted aircraft cost has only risen by about 2 6 per year a figure lower than the average observed general inflation rate for the period around 4 this represents an impressive average technological progress ratio of around 10 per year a revealed preferences argument shows that the characteristic most valued by the government is stealth capability followed by advanced avionics

measuring the impact of fiscal policy in the face of anticipation a structural var approach empirical estimates of the impact of government spending shocks disagree on central issues such as the size of output multipliers and the responses of consumption and the real wage one explanation for the disagreement is that fiscal shocks are often anticipated due to misspecification of the information set anticipation effects may invalidate svar estimates of impulse responses we use economic theory to derive a fiscal svar estimator that is applicable when fiscal shocks are anticipated we study its properties and apply it to us data we fail to find evidence that anticipation effects overturn the existing findings from the fiscal svar literature despite years of intensive research the empirical literature on fiscal policy has yet to reach consensus on the macroeconomic impact of fiscal policy shocks disagreements concern central issues such as the size of output multipliers and the impact of government spending shocks on consumption and the real wage clearly such level of disagreement constrains our ability to give simple guidelines for the operation of one of the most important stabilisation policies a key empirical obstacle is the measurement of innovations to fiscal policy one strand of the literature employs structural vector autoregressive svar methods and achieves identification based on the presence of decision lags or sign restrictions

on measuring the effects of fiscal policy in recessions we do not have a good measure of the effects of fiscal policy in a recession because the methods that we use to estimate the effects of fiscal policy both those using the observed outcomes following different policies in aggregate data and those studying counterfactuals in fitted model economies almost entirely ignore the state of the economy and estimate the government multiplier which is presumably a weighted average of the one we care about the multiplier in a recession and one we care less about the multiplier in an expansion notable exceptions to this general claim sug gest this difference is potentially large our lack of knowledge stems significantly from the focus on linear dynamics vector autoregressions and linearized or close to linear dynamic stochastic general equilibrium dsge models our lack of knowledge also reflects a lack of data deep recessions are few and nonlinearities hard to measure the lack of statistical power in the estimation of nonlinear models using aggregate data can be addressed by exploiting estimates of partial equilibrium responses in disaggregated data microeconomic estimates of the partial equilibrium causal effects of a policy can discipline the causal channels inherent in any dsge model of the general equilibrium effects of policy microeconomic studies can also provide measures of the dependence of the effects of a policy on the states of different agents which is a key component of the dependence of the general equilibrium effects of fiscal policy on the state of the

fiscal policy in good and bad times in this paper we analyze whether the effect of fiscal policy differs across the business cycle to tackle this question we use a regime switching error correction framework where nonlinearities are only modeled in the short run and have no impact on the long run equilibrium regime specific shocks to government revenue and government purchases are identified using sign restrictions linear combinations of the impulse responses of these basic shocks are used to construct a deficit spending shock and a deficit financed tax cut shock we find that active spending policies have a stronger impact in recession with multipliers exceeding unity and should be preferred to deficit financed tax cuts

why does private consumption rise after a government spending shock recent empirical evidence suggests that private consumption is crowded in by government spending this outcome violates existing macroeconomic theory according to which the negative wealth effect brought about by a rise in public expenditure should decrease consumption

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

discretionary tax changes and the macroeconomy new narrative evidence from the united kingdom abstract this paper provides new estimates of the macroeconomic effects of tax changes using a new narrative dataset for the united kingdom identification is achieved by isolating exogenous tax policy changes using the romer and romer narrative strategy i find that a 1 percent cut in taxes increases gdp by 0 6 percent on impact and 2 5 percent over three years the findings are remarkably similar to romer and romer narrative estimates for the united states reinforcing the view that tax changes have powerful and persistent effects exogenous tax changes are also shown to have contributed to important episodes in the uk business cycle jel e23 e32 e62 h20 h61

fiscal policy in the aftermath of 9 11 this paper investigates the nature of u s fiscal policy in the aftermath of 9 11 we argue that the recent declines in the government surplus and tax rates cannot be accounted for by either the state of the u s economy as of 9 11 or as the typical response of fiscal policy to a large exogenous rise in military expenditures our evidence suggests that had tax rates responded in the way they normally do to a large fiscal shock aggregate output would have been lower and the surplus would not have changed by much our results do not bear directly on the desirability of the decline in tax rates or the surplus after 9 11

effective tax rates in macroeconomics cross country estimates of tax rates on factor incomes and consumption abstract this paper proposes a method for computing tax rates using national accounts and revenue statistics using this method we construct time series of tax rates for large industrial countries the method identifies the revenue raised by different taxes at the general government level and defines aggregate measures of the corresponding tax bases this method yields estimates of effective tax rates on factor incomes and consumption consistent with the tax distortions faced by a representative agent in a general equilibrium framework these tax rates compare favorably with existing estimates of marginal tax rates and highlight important international differences in tax policy

measuring the effects of fiscal policy measuring the effects of discretionary fiscal policy is both difficult and controversial as some explicit or implicit identifying assumptions need to be made to isolate exogenous and unanticipated changes in taxes and government spending studies based on structural vector autoregressions typically achieve identification by restricting the contemporaneous interaction of fiscal and non fiscal variables in a rather arbitrary way in this paper we relax those restrictions and identify fiscal policy shocks by exploiting the conditional heteroscedasticity of the structural disturbances we use this methodology to evaluate the macroeconomic effects of fiscal policy shocks in the u s before and after 1979 our results show substantive differences in the economy s response to government spending and tax shocks across the two periods importantly we find that increases in public spending are in general more effective than tax cuts in stimulating economic activity a key contribution of this study is to provide a formal test of the identifying restrictions commonly used in the literature

rule of thumb consumers meet sticky wages it has been argued that rule of thumb consumers substantially alter the determinacy properties of simple interest rate rules and the dynamics of an otherwise standard new keynesian model in this paper we show that nominal wage stickiness helps re establishing standard results key findings are that wage stickiness i affects the shape of determinacy regions in the parameters space restoring the relevance of the taylor principle for the conduct of monetary policy ii implies that a rise in consumption in response to an innovation in government spending is not a robust feature of the model

using stock returns to identify government spending shocks this article explores a new approach to identifying government spending shocks which avoids many of the shortcomings of existing approaches the new approach is to identify government spending shocks with statistical innovations to the accumulated excess returns of large us military contractors this strategy is used to estimate the dynamic responses of output hours consumption and real wages to a government spending shock we find that positive government spending shocks are associated with increases in output hours and consumption real wages initially decline after a government spending shock and then rise after a year we estimate the government spending multiplier associated with increases in military spending to be about 1 5 over a horizon of 5 years

a stochastic dynamic programming model for scheduling of offshore petroleum fields with resource uncertainty abstract norwegian deliveries of natural gas to europe have grown considerably over the last years additionally plans involve even greater supplies introducing major gas fields as the troll field the market for natural gas may to a large extent be viewed as a contractual market this is normally explained by the big investments involved in development and transport in such a perspective the supplier s planning problem of scheduling fields and pipes may prove important in order to be able to meet contractual agreements this paper describes a model of stochastic dynamic programming type which may be viewed as a first attempt in solving this type of problem the main focus in this model is on project scheduling and resource uncertainty each project s production profile is viewed as a stochastic variable then a possible goal could be to minimize expected deviation from a given predicted contract profile we use the term spsp stochastic project scheduling problem to refer to our problem besides a simplified description of the mathematical model the paper also describes some tests with model examples these examples are constructed to obtain some interesting non intuitive effects the paper concludes with some remarks on complexity and speedup possibilities

investment adjustment costs an empirical assessment we evaluate empirical evidence for costs that penalize changes in investment using us industry data in aggregate models such investment adjustment costs have been introduced to help account for a variety of business cycle and asset market phenomena so far no attempt has been made to estimate these costs directly at a disaggregated level we consider an industry model with investment adjustment costs and estimate its parameters using generalized methods of moments the ndings indicate small costs associated with changing the ow of investment at the industry level the weighted average of the industry elasticities with respect to the shadow price of capital which depends inversely on the adjustment cost parameter is more than seven times larger than the largest estimate based on aggregate data we examine potential sources which may account for the large industry aggregate dierence overall our results suggest

heterogeneous consumers and fiscal policy shocks this paper studies empirical facts regarding the effects of unexpected changes in aggregate macroeconomic fiscal policies on consumers that are allowed to di er depending on their individual characteristics we use data from the consumption expenditure survey cex to estimate individual level impulse responses as well as multipliers for government spending the main empirical finding of this paper is that unexpected fiscal shocks have substantially different effects on consumers depending on their income and age levels in particular the wealthiest individuals tend to behave according to the predictions of standard rbc models whereas the poorest individuals tend to behave according to standard is lm non ricardian models most likely due to credit constraints furthermore government spending policy shocks tend to decrease consumption inequality forthcoming in journal of money credit and banking

how to reduce unemployment a new policy proposal this paper uses a model with a continuum of equilibrium steady state unemployment rates to explore the effectiveness of fiscal policy the existence of multiple steady state equilibria is explained by the presence of search and recruiting costs i use the model to explain the current financial crisis as a shift to a high unemployment equilibrium induced by the self fulfilling beliefs of market participants about asset prices i ask two questions 1 can fiscal policy help us out of the crisis 2 is there an alternative to fiscal policy that is less costly and more effective the answer to both questions is yes

government spending entry and the consumption crowding in puzzle this article documents empirically that net firm entry robustly rises after a u s government spending expansion we use this new finding to test the empirical validity of various model features that have been proposed to generate consumption crowding in after positive expenditure shocks endogenous entry models typically fail to generate the observed joint increase in consumption and entry model features that dampen the wealth effect such as rule of thumb households or complementarity between labor and consumption in preferences tend to reduce entry we show that utility or productivity enhancing public spending can reconcile the model with our documented fact and performs well empirically

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

factor hoarding and the propagation of business cycles shocks this paper analyzes the role of variable capital utilization rates in propagating shocks over the business cycle to this end we formulate and estimate an equilibrium business cycle model in which cyclical capital utilization rates are viewed as a form of factor hoarding we find that variable capital utilization rates substantially magnify and propagate the impact of shocks to agents environments the strength of these propagation effects is evident in the dynamic response functions of various economy wide aggregates to shocks in agents environments in the statistics that we construct to summarize the strength of the propagation mechanisms in the model and in the volatility of exogenous technology shocks needed to explain the observed variability in aggregate u s output other authors have argued that standard real business cycle rbc models fail to account for certain features of the data because they do not embody quantitatively important propagation mechanisms these features include the observed positive serial correlation in the growth rate of output the shape of the spectrum of the growth rate of real output and the correlation between the forecastable component of real output and various other economic aggregates allowing for variable capital utilization rates substantially improves the ability of the model to account for these features of the data

fiscal policy monopolistic competition and finite lives abstract this paper studies the short run transitional and long run output effects of permanent and temporary shocks in public consumption under various financing methods to this end a dynamic macroeconomic model for a closed economy is developed which features a perfectly competitive final goods sector and a monopolistically competitive intermediate goods sector finitely lived households consume final goods supply labor and save part of their income amongst the findings for a permanent rise in public consumption are i monopolistic competition increases the absolute value of the balanced budget output multiplier ii positive long run output multipliers are obtained only if the generational turnover effect is dominated by the intertemporal labor supply effect iii short run output multipliers under lump sum tax financing are smaller than long run output multipliers if labor supply is elastic and iv bond financing reduces the size of long run output multipliers as compared to lump sum tax financing and may give rise to non monotonic adjustment paths if labor supply is sufficiently elastic and the speed of adjustment of lump sum taxes is not too high temporary bond financed fiscal shocks are shown to yield i permanent effects on output and ii negative long run output multipliers

fiscal policy the real exchange rate and traded goods we estimate the effects of government spending shocks on the cpi real exchange rate the trade balance and their co movements with gdp and private consumption we decompose the variations of the cpi real exchange rate into variations of the traded goods real exchange rate and the relative price of traded to non traded goods we reach three main conclusions a rise in government spending induces a depreciation of the cpi real exchange rate and a trade balance deficit private consumption rises in response to a government spending shock and therefore co moves positively with the real exchange rate both components of the cpi real exchange depreciate we employ vector auto regression var techniques to estimate the effects of fiscal policy and in particular government spending on the cpi real exchange rate and the trade balance in the us and three other oecd countries our empirical analysis delivers two key results first a rise in government spending tends to induce a real exchange rate depreciation and a trade balance deficit although especially in the us the latter effect tends to be small second in all countries private consumption rises in response to a government spending shock and therefore co moves positively with the real exchange rate two important implications follow from these results our evidence provides support for a traditional twin deficit hypothesis in stark contrast with a recent study by kim and roubini 2008 a second implication concerns the consistency of facts and theory both the response of the real exchange rate and its co movement with private consumption and the trade balance are at odds with a benchmark general equilibrium open economy model featuring complete financial markets in fact while the model is successful in replicating the negative response of the trade balance to a government spending shock that we observe in the data and also in linking the magnitude of that response to the degree of openness it has counterfactual predictions on the response of the real exchange rate and of private consumption we argue that the key failure of the model lies in the equilibrium behaviour of private consumption in the model as a result of a typical wealth effect on labour supply private consumption falls in response to a rise in government spending whereas the opposite is true in the data this in turn explains the behaviour of the real exchange rate in the reference model with complete asset markets a risk sharing arbitrage condition ties the ratio of the marginal utilities of consumption across countries to the real exchange rate via this condition and provided that deviations from purchasing power parity are feasible the fall in consumption is accompanied by an equilibrium appreciation of the real exchange rate we proceed by investigating further the sources of the cpi real exchange rate movements in the data a traditional approach decomposes the real exchange rate into two terms

natural gas corridors between the eu and its main suppliers simulation results with the dynamic gastale model abstract growth in gas demand poses a challenge for european energy consumers and other gas importing countries in terms of an increasing dependency on gas imports and consequently also supply security this paper focuses on interactions among demand supply and investments in natural gas corridors namely pipeline transport lng and storage facilities affecting the european natural gas market over the period 2005 2030 a number of policy scenarios including a business as usual bau scenario are formulated to study the impact of demand uncertainty and delays in investment on the gas transport infrastructure required in the long run in europe the analyses indicate that substantial investments in gas transport corridors are needed to accommodate imports and seasonal demand variations analysis of scenarios of supply interruption in the form of suddenly reduced import capacity for particular pipeline routes indicates that portions of europe could experience price increases of up to 100 in the case of a year long interruption to accommodate import needs and to mitigate possible disruptions pipeline connections running from east to west need to be given special priority

can government purchases stimulate the economy this essay briefly reviews the state of knowledge about the government spending multiplier drawing on theoretical work aggregate empirical estimates from the united states as well as cross locality estimates i assess the likely range of multiplier values for the experiment most relevant to the stimulus package debate a temporary deficit financed increase in government purchases i conclude that the multiplier for this type of spending is probably between 0 8 and 1 5 jel e23 e62 h50

on fiscal multipliers estimates from a medium scale dsge model this paper contributes to the debate on fiscal multipliers in the context of a structural model i estimate a micro founded dynamic stochastic general equilibrium model that features a rich fiscal policy block and a transmission mechanism for government spending shocks using bayesian techniques for us data

housework and fiscal expansions in an otherwise standard business cycle model with housework calibrated consistently with data on time use we discipline complementarity between consumption and hours worked and relate its strength to the size of fiscal multipliers evidence on the substitutability between home and market goods confirms that complementarity is an empirically relevant driver of fiscal multipliers however in a housework model substantial complementarity can be generated without imposing a low wealth effect which contradicts the microeconomic evidence also explicitly modeling housework matters for assessing the welfare effects of government spending which are understated by theories that neglect substitutability between home produced and market goods

resurrecting the weak credibility hypothesis in models of exchange rate based stabilization abstract we analyze how weak credibility affects the volatility of consumption spending in a model of exchange rate based stabilization that allows for both durable and nondurable goods the inclusion of durables greatly improves the explanatory power of the weak credibility hypothesis the hypothesis can account for the main qualitative properties of the boom bust cycle provided the elasticity of durables expenditure with respect to tobin s q is greater than the intertemporal elasticity of substitution moreover the quantitative effects are very large in numerical simulations based on conservative assumptions about the expenditure share of durables 20 and wealth effects none aggregate consumption increases 17 22 and the real exchange rate appreciates 24 26 when the crawl decreases from 100 to zero for 3 years in variants of the model that incorporate supply effects the consumption boom is equally strong but appreciation of the real exchange rate rises to 30 40

fiscal policy in a tractable liquidity constrained economy we analyse the effects of fiscal expansions when public debt is used as liquidity by the private sector aggregate shocks are introduced into an incomplete market economy where heterogenous agents face occasionally binding borrowing constraints and store wealth to smooth out idiosyncratic income fluctuations debt financed increases in spending facilitate self insurance by bond holders and may crowd in private consumption they also loosen the borrowing constraints faced by firms thereby raising labour demand and possibly the real wage whether private consumption and wages rise or fall ultimately depends on the relative strengths of the liquidity and wealth effects that arise following the shock

fiscal policy and occupational employment dynamics we document substantial heterogeneity in occupational employment dynamics in response to government spending shocks in the united states employment rises most strongly in service sales and office pink collar occupations by contrast employment in blue collar occupations is hardly affected by fiscal policy we provide evidence that occupation specific changes in labor demand are key for understanding these findings we develop a business cycle model that explains the heterogeneous occupational employment dynamics as a consequence of composition effects due to heterogeneous employment changes across industries and occupation specific within industry employment shifts due to differences in the short run substitutability between labor and capital services across occupations

identifying discretionary fiscal policy reactions with real time data we propose a method of identifying discretionary fiscal policy reactions using real time data automatic stabilizers should depend on true gdp while discretionary fiscal policy is contingent on the information that policy makers have in real time we can compute a real time measurement error by comparing the first release of gdp data with later revisions discretionary fiscal policy is influenced by this measurement error whereas automatic fiscal policy is not we use this identification approach to test the central identifying assumption of blanchard and perotti s 2002 seminal structural vector autoregression var according to this assumption fiscal policy makers do not react to gdp developments contemporaneously in a discretionary fashion we find that government expenditure is adjusted upward if gdp growth in real time is lower than true gdp this suggests that fiscal policy makers use short term funds to buy goods and services in response to their perception of gdp dynamics

unemployment fiscal multipliers we estimate the effects of fiscal policy on the labor market in us data an increase in government spending of 1 percent of gdp generates output and unemployment multipliers respectively of about 1 2 percent at one year and 0 6 percentage points at the peak each percentage point increase in gdp produces an increase in employment of about 1 3 million jobs total hours employment and the job finding probability all rise whereas the separation rate falls a standard neoclassical model augmented with search and matching frictions in the labor market largely fails in reproducing the size of the output multiplier whereas it can produce a realistic unemployment multiplier but only under a special parameterization extending the model to strengthen the complementarity in preferences to include unemployment benefits real wage rigidity and or debt financing with distortionary taxation only worsens the picture new keynesian features only marginally magnify the size of the multipliers when complementarity is coupled with price stickiness however the magnification effect can be large

the effects of government spending shocks on the real exchange rate and trade balance in turkey the aim of this study is to investigate the effects of government spending shocks on the real exchange rate and foreign trade balance in turkey for the period of 2002 01 2012 04 within a structural var framework the analysis shows that a positive shock to the government spending tends to induce real exchange rate appreciation and deterioration in trade balance we also find that the composition of the government spending matters although shocks to the government nonwage consumption generate an appreciation in the real exchange rate and worsening of the trade balance the effects of government investment shocks remain insignificant furthermore the analysis demonstrates that shocks to government spending are associated with a rise in taxes which is indicative of a spending driven tax adjustment process in turkey

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

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

on the size of government spending multipliers in europe this article compares the size of government spending multipliers in europe by applying a panel structural vector autoregression analysis on 11 eurozone and 8 non eurozone countries using quarterly data from 1991q1 to 2012q4 we find that i spending multipliers are smaller in eurozone compared to non eurozone countries ii across the euro area the impact of government spending on gdp has been higher before than after the introduction of the euro iii spending multipliers are larger in the eurozone periphery than in the core countries and iv since the beginning of the recent financial crisis spending multipliers have become larger both for eurozone and for non eurozone countries we relate these results to an emerging theoretical literature linking the size of fiscal multipliers to the monetary policy stance we also discuss the implications of our findings for the effectiveness of fiscal policy in europe

habit formation adjustment costs and international transmission of fiscal policy abstract the paper studies the effects of fiscal policy in an integrated world economy the setup is one with habit forming endogenous rates of time preference and adjustment costs in investment most of the predictions of the model are in line with the recent empirical literature on fiscal policy for instance in response to a balanced fiscal expansion we obtain positive long run output multipliers long run increases in employment short and medium run increases in wages and decreases in investment our results suggest that short run government spending multipliers are smaller than tax multipliers most importantly we show that the model can generate positive short and medium run consumption responses to a positive fiscal shock this is relevant as negative consumption responses are considered to be one of the main challenges facing neo classical models of fiscal policy

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

optimizing short term natural gas supply portfolio for electric utility companies natural gas fired power plants ngfpp are important electricity generation resources in the united states optimizing the natural gas supply portfolio especially the short term portfolio is critical for the day to day operations and the financial performance of ngfpps traditionally such optimization problems are solved using cost minimization based frameworks however such frameworks are facing challenges due to the lack of consideration of associated financial risks in the current deregulated electricity markets which the electric utility companies eucs who own and operate ngfpps now bear this paper presents a utility maximization based framework to optimize the short term natural gas supply portfolio for the euc it considers the financial risks associated with the portfolio and incorporates the risk preferences of the eucs as decision maker dm in the portfolio optimization process an application of the proposed framework is provided and its results show that the proposed framework is more desirable in terms of risk cost trade off optimization

robust strategies for natural gas procurement abstract in order to serve their customers natural gas local distribution companies ldcs can select from a variety of financial and non financial contracts the present paper is concerned with the choice of an appropriate portfolio of natural gas purchases that would allow a ldc to satisfy its demand with a minimum tradeoff between cost and risk while taking into account risk associated with modeling error we propose two types of strategies for natural gas procurement dynamic strategies model the procurement problem as a mean risk stochastic program with various risk measures naive strategies hedge a fixed fraction of winter demand the hedge is allocated equally between storage futures and options we propose a simulation framework to evaluate the proposed strategies and show that i when the appropriate model for spot prices and its derivatives is used dynamic strategies provide cheaper gas with low risk compared to naive strategies ii in the presence of a modeling error dynamic strategies are unable to control the variance of the procurement cost though they provide cheaper cost on average based on these results we define robust strategies as convex combinations of dynamic and naive strategies the weight of each strategy represents the fraction of demand to be satisfied following this strategy a mean variance problem is then solved to obtain optimal weights and construct an efficient frontier of robust strategies that take advantage of the diversification effect

equity returns and business cycles in small open economies this is the first paper in the literature to match key business cycle moments and long run equity returns in a small open economy with production these results are achieved by introducing three modications to a standard real business cycle model 1 borrowing and lending costs are imposed to increase the volatility of the intertemporal marginal rate of substitution 2 investment adjustment costs are assumed to make equity returns more volatile and 3 ghh preferences are employed to smooth consumption we also decompose the contributions of productivity the world interest rate and government expenditure shocks to the equity premium our results are based on data from argentina brazil and chile

what do british historical data tell us about government spending multipliers british data from the early 1700s through world war i reflect the results of numerous high quality natural experiments of government spending britain frequently participated in wars increasing military spending massively wartime distortions were relatively limited because the government generally adopted tax smoothing policy and rarely implemented interventions government spending multiplier estimates are low or negative and significantly below unity this paper finds no evidence that the multiplier was higher in the slack state than in the normal state jel e32 e62

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

the effects of public spending externalities abstract we conduct a positive analysis on the effects of externalities produced by government spending to this effect we estimate using u s data an rbc model with two salient features first we allow government consumption to directly affect the marginal utility of consumption second we allow public capital to shift the productivity of private factors we provide an identification analysis that supports the strategy adopted for estimating the parameters governing these two channels on one hand private and government consumption are robustly estimated to be substitute goods because of substitutability labor supply reacts little to a government consumption shock so the estimated output multiplier is much lower than in models with separabilities on the other hand our results point towards public investment being unproductive

debt and deficit fluctuations and the structure of bond markets we analyse the implications of optimal taxation for the stochastic behaviour of debt we show that when a government pursues an optimal fiscal policy under complete markets the value of debt has the same or less persistence than other variables in the economy and it declines in response to shocks that cause the deficit to increase by contrast under incomplete markets debt shows more persistence than other variables and it increases in response to shocks that cause a higher deficit data for us government debt reveals diametrically opposite results from those of complete markets and is much more supportive of bond market incompleteness

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 dynamic effects of neutral and investment specific technology shocks the neoclassical growth model is used to identify the short run effects of neutral technology shocks which affect the production of all goods homogeneously and investment specific shocks which affect only investment goods the real equipment price crucial for identifying the investment shocks experiences an abrupt increase in its average rate of decline in 1982 so the analysis is based on a split sample on the basis of the preferred specification the two technology shocks account for 73 percent of hours and 44 percent of output s business cycle variation before 1982 and 38 percent and 80 percent afterward the shocks also account for more than 40 percent of hours and 58 percent of output s forecast errors over a three to eight year horizon in both samples the majority of these effects are driven by the investment shocks

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

new keynesian versus old keynesian government spending multipliers renewed interest in fiscal policy has increased the use of quantitative models to evaluate policy because of modelling uncertainty it is essential that policy evaluations be robust to alternative assumptions we find that models currently being used in practice to evaluate fiscal policy stimulus proposals are not robust government spending multipliers in an alternative empirically estimated and widely cited new keynesian model are much smaller than in these old keynesian models the estimated stimulus is extremely small with gdp and employment effects only one sixth as large and with private sector employment impacts likely to be even smaller we investigate the sensitivity of our findings with regard to the response of monetary policy the zero bound on nominal interest rates and the inclusion of an empirically relevant degree of rule of thumb behaviour in the new keynesian model in addition we relate our findings using estimated structural macroeconomic models to the recent literature using reduced form regression techniques

fiscal policy pricing frictions and monetary accommodation this paper empirically investigates whether the theoretical conditions for government expenditure expansions to be effective hold for the data we ask whether the necessary conditions for fiscal effectiveness are relevant on average and in special circumstances that capture features of the recent crisis fiscal policy can be an effective countercyclical tool if monetary policy accommodates the fiscal expansion if expectations about future output growth and inflation are constant and if structural relationships are invariant to the policy change recent expansions are unlikely to produce large output multipliers or have important debt or inflation effects credible deficit and debt reduction schemes can produce sizeable output multipliers fabio canova and evi pappa

exchange rate based stabilisation durables consumption and the stylised facts in this article we show that a model featuring durable consumer goods imperfect substitution between domestic and foreign assets and weak credibility can explain the qualitative and quantitative aspects of the stylised facts associated with exchange rate based stabilisation including the tremendous increase in real interest rates following a temporary reduction in the crawl total consumption spending rises 14 26 the real exchange rate appreciates 20 37 and the current account deficit swells to 10 15 of gross domestic product despite large capital inflows the real interest rate increases from 10 to 20 100
