modelling seasonality in residential water demand the case of tunisia this article proposes to model seasonal patterns of residential water demand using the techniques of seasonal integration and cointegration the methodology is applied to quarterly aggregate time series data for tunisia 1980 2007 applying the same increasing multi step pricing scheme in the whole country first a seasonal cointegration analysis demonstrates the relevance of a pricing policy that increases the size of the lower consumption block in summer second the nonseasonal cointegration analysis reveals a relatively high price elasticity for the highest consumption block therefore we also propose to increase the tariff progressivity to promote water savings this modified pricing scheme will help to achieve goals of environmental protection and social equity

shifts in the composition of government spending in response to external debt burden abstract this paper examines the effects of external public debt burden on the composition of public spending in a sample of 47 developing countries for 1972 2001 we specify a system of equations for the relative spending shares of six economic categories and estimate it using several estimation methods and samples we find support for the adverse effect of the debt burden on capital expenditure in the full sample and in the middle east north africa and sub saharan africa subsamples where the debt burden was relatively high among components of current expenditure increased debt burden shifted the shares against nonwage goods services and subsidy and transfers while leaving the share of politically sensitive category of wages and salaries unscathed in most cases

a note on price perception in water demand models a household s decision to acquire price knowledge is endogenous in the demand for utility services and may affect elasticities and consumption levels a simultaneous equation model with endogenous switching is developed to evaluate the effects of price

general equilibrium impact of an energy saving policy in the public sector we analyse a disregarded environmental policy instrument a switch in government expenditure away from energy or other natural resources and toward a composite good which includes energy saving expenditure we first develop two variants of an analytical general equilibrium model a composite good is produced with constant returns to scale and energy is imported or produced domestically with diminishing returns yielding a differential rent to its owners the government purchases energy and composite goods from private firms such a policy unambiguously increases employment it also raises private consumption and welfare under two conditions i it is not too costly and ii the initial share of the resource is smaller in public spending than in private consumption or the difference is small enough we then run numerically a model featuring both importation and domestic production of energy oil gas and electricity for the oecd as a whole simulations show that employment welfare and private consumption rise we provide magnitudes for different parameter values

public capital asymmetric information and economic growth we investigate the provision of public capital in an endogenous growth model with asymmetric information in a credit market with costly screening we show that the equilibrium contracts are characterized by the self selection of borrowers through identifying an additional adverse effect of taxation on growth we show that the optimal tax rate in our model is smaller than the output elasticity of public capital therefore our analysis justifies a more conservative tax policy in the presence of asymmetric information furthermore our model suggests a number of implications that appear to be well supported by preliminary evidence in cross country data jel classification d82 h21 041

fiscal policy and the term structure of interest rates an intertemporal optimizing analysis the effects of government expenditure on the dynamic evolution of the term structure of interest rates are analyzed in an infinite horizon intertemporal optimizing macroeconomic framework three types of disturbances are discussed unanticipated and anticipated permanent increases and a temporary decrease in the case of anticipated future and temporary disturbances the lead time in the former and the duration in the latter are critical determinants of the dynamics for a very temporary shock the short term and long term rates will diverge in the short run while most of the analysis focuses on infinitesimally short and infinitely long bonds the dynamics of the entire yield curve are also considered copyright 1992 by ohio state university press

schooling and public capital in a model of endogenous growth this paper studies the allocation of public spending between education services and infrastructure investment in an endogenous growth model where public capital in infrastructure affects the process of human capital accumulation the balanced growth path is derived and the dynamics associated with a budget neutral reallocation of spending from education to infrastructure are studied through numerical simulations the growth maximizing tax rate is shown to depend only on the production technology as in standard flow models of public expenditure whereas the optimal share of infrastructure investment depends also on the productiveness of infrastructure relative to education services in the schooling technology

the dual nature of public goods and congestion the role of fiscal policy revisited the role of fiscal policy is examined when public goods provide both productive and utility services in the presence of congestion the consumption tax is shown to be distortionary optimal fiscal policy involves using consumption based instruments in conjunction with the income tax an income tax financed increase in government spending dominates both lump sum and consumption tax financing replacing the lump sum tax with an income tax to finance a given level of spending dominates introducing an equivalent consumption tax these results contrast sharply with the literature where the consumption tax is generally viewed as the least distortionary source of public finance on re examine le role de la politique fiscale quand les biens publics fournissent a la fois des services productifs et de bien etre quand il y a congestion on montre que la taxe sur la consommation cree des distorsions la politique fiscale optimale consiste a faire bon usage des taxes sur la consommation en conjonction avec l impot sur le revenu une depense gouvernementale financee par l impot sur le revenu est preferable a un financement par un paiement forfaitaire ou une taxe sur la consommation remplacer le paiement forfaitaire par un impot sur le revenu pour financer un niveau donne de depense vaut mieux qu introduire une taxe equivalente sur la consommation ces resultats contrastent vivement avec ce qu on trouve dans la litterature specialisee ou l on considere generalement la taxe sur la consommation comme la source de finance publique qui cree le moins de distorsion

optimal taxation and intergovernmental transfer in a dynamic model with multiple levels of government abstract in this paper we study the optimal choices of the federal income tax federal transfers and local taxes in a dynamic model of capital accumulation and with explicit game structures among multiple private agents multiple local governments and the federal government in general the optimal local property tax is zero if the local property tax is constrained to be nonnegative whereas the optimal local consumption tax is always positive when the local consumption tax is chosen optimally the federal income tax can be either positive or negative for most reasonable parameter values our numerical calculations have shown that with a positive local consumption tax there exists a reverse transfer from local governments to the federal government

public infrastructure investment output dynamics and balanced budget fiscal rules abstract we study the dynamic macroeconomic effects of public infrastructure investment under a balanced budget fiscal rule using an overlapping generations model of a small open economy the government finances public investment by employing distortionary labor taxes the balanced budget rule implies a negative short run output multiplier that exceeds in absolute terms the positive long run output multiplier larger public capital spillovers sharpen the intertemporal output tradeoff in contrast to conventional results regarding public investment shocks we obtain dampened cyclical responses for plausible parameter values the cyclical dynamics arise from the interaction between the labor tax rate the tax base and the intergenerational spillover effects we show that financing scenarios involving public debt creation can substantially reduce the short run output contraction and the transitional macroeconomic fluctuations induced by public investment

public capital and imperfect competition abstract in this paper we consider a macroeconomic model in which public capital is a productive input and there is monopolistic competition in the product market we analyze the effects of a permanent variation in public capital investment both in the short and in the long run finally we show that the optimal provision of public capital under imperfect competition is higher than that associated with the first best policy

government spending and the optimal rates of consumption and capital accumulation this paper investigates the effects of a temporary change in government expendit ure on private consumption and investment the model employed is one of a closed economy populated by infinitely lived utility maximizing individuals the analysis focuses on the implications of alternative assumptions concerning the relationship between public and private c onsumption in the household s utility function a temporary increase in government expenditure is found to reduce investment if public and private goods are edgeworth complements or independent however if they are substitutes there exists the possibility of an increase in investment

alternate price specifications for estimating residential water demand with fixed fees using a new model formulation and data from a sample of colorado utilities we investigated the price specification controversy marginal price versus average revenue when estimating residential water demand the improved statistical fit using average revenue as the price variable was shown to be an artifact of the unitary elastic identity created when monthly rate schedules contain a fixed fee when the fixed fee was purged from the data average price was not significant but marginal price remained significant in the preferred double log marginal price model estimated price elasticity was 0 3 and conservation programs had no significant effect on water use

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

output effects of government purchases the theoretical analysis focuses on the distinction between temporary and permanent movements in government purchases under plausible conditions the temporary case involves an output response that is positive less than one to one with the change in government purchases and larger than that generated by an equal sized but permanent shift in purchase the equilibrium real rate of return rise in the temporary case but changes little in the permanent one defense purchases are divided empirically into permanent and temporary components by considering the role of temporary wars no temporary shifts in nondefense purchases were isolated empirical results verify an expansionary output effect for temporary purchases that exceeds that of permanent purchases the results for some other expectational hypotheses are found to be generally supportive of the theory

government spending endogenous labor and capital accumulation following turnovsky and fisher 1995 journal of economic dynamics and control 19 747 786 we reexamine the dynamic responses of the capital stock to an unanticipated temporary increase in government consumption and infrastructure expenditures the key factors determining capital accumulation are endogenous labor the duration of policy expansion and the relationship between private decisions and the composition of public expenditure given that private decisions and public consumption are edgeworth independent if employment is variable investment increases with the duration of fiscal expansion following a temporary public infrastructure expansion there always exists the possibility of a decrease in investment before the fiscal reversion under fixed employment however a temporary public infrastructure expansion under variable employment leads to a likely increase in investment before the fiscal reversion

an empirical survey of residential water demand modelling abstract the increased reliance on demand side management policies as an urban water consumption management tool has stimulated considerable debate among economists water utility managers regulators consumer interest groups and policymakers in turn this has fostered an increasing volume of literature aimed at providing best practice estimates of price and income elasticities quantifying the impact of non price water restrictions and gauging the impact of non discretionary environmental factors affecting residential water demand this paper provides a synoptic survey of empirical residential water demand analyses conducted in the last 25 years both model specification and estimation and the outcomes of the analyses are discussed

does precommitment raise growth the dynamics of growth and fiscal policy we develop an endogenous growth model driven by externalities from both private and public capital the government levies distortionary taxation to finance a publicly provided consumption good and public infrastructure firms face adjustment costs we compare the optimal and time consistent policies in a linear quadratic approximation of the model although the timeconsistent equilibrium is sub optimal in terms of ex ante intertemporal welfare it yields higher long run growth and welfare through an accumulation of assets by the state and a cut in government consumption

are bond financed deficits inflationary a ricardian analysis this paper considers the possible theoretical validity of the following monetarist hypothesis that a constant positive government budget deficit can be maintained permanently and without inflation if it is financed by the issue of bonds rather than money the question is studied in a discrete time perfect foresight version of the competitive equilibrium model of sidrauski modified by the inclusion of government bonds as a third asset it is shown that the monetarist hypothesis is invalid if the deficit is defined exclusive of interest payments but that it is valid under the conventional definition it is also shown that the stock of bonds can grow indefinitely at a rate in excess of the rate of output growth provided that the difference is less than the rate of time preference these formal conclusions do not take account of possible limitations on taxing capacity arising from default incentives that tend to grow with the stock of bonds

estimation of residential water demand with imperfect price perception using data from a household survey carried out in the french overseas territory of reunion we investigate the price of drinking water perceived by households faced with an increasing multi step pricing scheme to this purpose we use an improved version of the method introduced by shin 1985 to estimate the demand for residential water when consumers are imperfectly informed about their pricing schedule the empirical results suggest that reunion households underestimate the price of water and thus consume more than what is economically rational providing information to households about the marginal price of water may be an innovative means of inducing them to respond to pricing policies designed to promote water conservation

demand and distributional effects of water pricing policies abstract worldwide water scarcity threatens delivery of water to urban centers water pricing is often recommended to reduce demand in this paper demand and distributional effects of water pricing policies are examined in a block pricing model that is applied to the metropolitan region of sao paulo water demand functions are estimated using marginal and average price models based on monthly data for the period 1997 2002 price elasticities of water demand range between 0 45 and 0 50 and income elasticities between 0 39 and 0 42 for the current combined regressive progressive block price system the poor spend almost 4 2 to 4 7 of their income on water the rich only pay 0 4 to 0 5 of their income whereas they consume more than twice as much a progressive block price or an income dependent price system may result in a more equalized income distribution however the analysis shows that there is a trade off between a more equalized income distribution and revenues earned by the water company more pro poor pricing systems may result as well in lower revenues for the water company

the heterogeneous responses of consumption between poor and rich to government spending shocks government spending shocks have substantially different effects on consumers across the income distribution consumption increases for the poor whereas it decreases for the rich in response to a rise in government expenditure i shed light on this issue by incorporating a progressive tax scheme and productive public expenditure into a heterogeneous agent model economy with indivisible labor the model economy is able to successfully match aggregate and disaggregate effects of government spending shocks on consumption when the government increases its spending and accompanies it by a rise in tax progressivity the poor are employed and increase their consumption since after tax wage rates increase while the rich decrease their consumption because of a fall in after tax wage rates

public capital and total factor productivity this paper examines the impact of the stock of public capital on output levels and productivity growth rates in the united states the analysis is based on the estimation of parameters in a translog profit function prices of intermediate goods are introduced into a quasiproduction function for value added recently developed econometric techniques for dealing with nonstationary time series are used in the estimation the authors find that the services of public capital are an important part of the production process and that about 40 percent of the productivity decline is explained by a fall in the public capital labor ratio copyright 1993 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

endogenous structural breaks public investment in agriculture and agricultural land productivity in taiwan using time series data for taiwan s agricultural sector and with the government s public investment in the agricultural sector serving as a proxy variable for nonfarm current inputs aside from the original labour and capital input variables usually taken into consideration this article examines the relationship between public investment in agriculture public investment land and agricultural land productivity output land in taiwan our main findings are as follows first the cointegration test reveals that public investment in agriculture and the productivity of agricultural land exhibit a significant positive relationship in the long run where the elasticity of land productivity in relation to public investment in agriculture is 0 55 second when controlling for endogenous structural breaks the long run equilibrium relationship for the productivity of the agricultural land model is still supported third the results of the weak exogeneity test indicate that a causal relationship exists in the lo

determinants of residential water demand in germany abstract we econometrically analyze the impact of several economic environmental and social determinants for the per capita demand for water in about 600 water supply areas in germany besides prices income and household size we consider the effects of population age the share of wells housing patterns precipitation and temperature we also explore why current per capita residential water consumption in the new federal states is about 30 lower than in the old federal states since average cost pricing may cause an endogeneity problem we apply instrumental variable procedures in addition to single equation ordinary least squares but find no evidence that prices are endogenous our estimation results suggest that the price elasticity of water demand in germany is around 0 24 the income elasticity is positive decreases with higher income levels and is at least three times higher in the new federal states than in the old federal states current differences in prices and income levels explain about one third of the gap in residential water use between the two regions household size and the share of wells have a negative impact on per capita water demand and water use increases with age finally the findings provide some evidence that rainfall patterns rather than total rainfall affect water consumption while temperature appears to have no impact at all all outcomes are robust to a log log and two types of semi log specifications for the water demand function

public spending reallocations and economic growth across different income levels this paper examines the effects of public spending reallocations on economic growth assembling a disaggregated public spending dataset of 83 countries over the 1970 2011 period we show that spending reallocations towards education from health and social protection have significant growth promoting effects across a wide range of countries income levels however income heterogeneity matters particularly when reallocations involve infrastructure spending specifically a reallocation from this spending to education also promotes growth albeit primarily when the income level is low this occurs because the effects of infrastructure spending are particularly weak in low income countries possibly due to the low quality of governance

efficiency and equity in natural resources pricing a proposal for urban water distribution service this paper focuses on the design of optimal prices for urban water distribution service in this context pricing should be aimed at achieving efficiency equity financial aspects and or public acceptability and transparency the proposed tariffs are based on the theoretical frameworks suggested by ramsey 1927 and feldstein 1972 as a prior step estimations of urban water demands and water costs are carried out for the spanish municipality of seville finally an empirical comparison in welfare terms is conducted between the proposed tariffs and those applicable in the year 2000

government debt government spending and private sector behavior a current period tax reduction financed by issuing government debt shifts the timing of tax collection from the current period to the future if the future taxes implied by government debt are not fully perceived and discounted by the private sector there will be a net wealth effect that increases private sector consumption thus reducing capital accumulation and growth if on the other hand the implied future taxes are perceived and discounted by the private sector the current period tax reduction will be used to increase private saving to pay for the future taxes and government debt will be absorbed without any real effects on the economy the effects of government spending financed by current period taxation also depend upon private sector perceptions 2 if the benefits of government spending are ignored private sector consumption will decrease in accordance with the reduction in permanent disposable income to the extent that government spending is on consumption type goods that are perceived as substitutes for privately provided consumption goods there will be a relatively greater reduction in private sector consumption to the extent that government spending is on investment type goods yielding future goods and services that are perceived as substitutes for future privately provided consumption goods there will be a relatively smaller reduction in private sector consumption the standard approach to modeling private sector consumption saving behavior involves a rather asymmetric set of assumptions as to how the private sector perceives the various elements of government fiscal policy 3 current period taxes are assumed to be fully perceived but current period government spending is implicitly assumed to be completely ignored by the private sector in considering permanent personal disposable income the private sector is assumed to be forward looking in its assessment of income and taxation the stock of government debt is nevertheless included as part of the stock of private wealth the implicit assumption associate professor of economics graduate school of business university of chicago 1101 east 58th street chicago il 60637 i thank eugene fama levis kochin michael mussa paul evans and an anonymous referee for helpful comments i am particularly grateful to daniel benjamin for contributing many hours of discussion and laura lahaye who was a research assistant and valuable adviser on earlier drafts the theoretical debate on the burden of the debt has been long standing gerald o driscoll 1977 documents ricardo s nineteenth century position robert barro 1974 reopened the debate by introducing the fundamental issue of intergenerational transfers also discussed in merton miller and charles upton 1974 the empirical side of the debate was initiated by levis kochin s 1974 attempt to test for the effects of deficits on consumption and by martin feldstein s 1974 attempt to test for the effects of social security wealth on consumption other empirical contributions include jess yawitz and laurence meyer 1976 myself 1978 and j earnest tanner 1978 1979 with respect to the effects of government deficits and debt and barro 1978 michael darby 1979 and dean leimer and selig lesnoy 1982 with respect to social security wealth see also interesting recent papers by john seater 1982 who generates detailed tests of the effects of deficits and debt on consumption charles plosser 1982 who explores the effects of government spending and debt shocks on interest rates and feldstein 1982 who attempts tests similar to some in this paper see fn 29 2martin bailey s 1962 1971 development of the effects of government spending on private consumption and aggregate economic activity is the seminal contribution paul david and john scadding 1974 extend bailey s ideas and provide some supporting empirical evidence more recently willem buiter 1977 and myself 1978 developed models based on bailey s earlier work barro 1981 has an interesting paper on related issues see also david aschauer 1982 3the standard approach incorporates fiscal policy through the concept of personal disposable income and by including the stock of government debt as part of personal wealth see for example the empirical specification of albert ando and franco modigliani 1963 which has been the basis of most empirical consumption studies since and feldstein 1974 for one of the more influential papers based on the ando modigliani specification

perspectives on multinational enterprises in emerging economies multinational enterprises mnes play a pivotal role in the development of many emerging economies in consequence they became the focus of scholarly research by economists and policy analysts in contrast international business scholars have been comparatively uninterested in analysing this role of mnes yet they could make important contributions to these debates first studies taking the individual firms as starting point would enhance understanding of the interaction between mnes and the local environment second theories and research methodologies developed in international business research could provide new insights into the dynamics of mnes in emerging economies the objective of this paper is to motivate more international business scholars to engage in research on positive and negative spillovers from foreign direct investment fdi in emerging economy societies to advance this research agenda scholars need to analyse the specific activities and capabilities of the firms involved and the impact of fdi on the broader social and environmental context for management this agenda raises the ethical question to what extent ought businesses to care about their local stakeholders

public investment congestion and private capital accumulation this paper analyses the impact of public investment on the dynamics of private capital formation in an intertemporal optimising market clearing framework the key feature characterising the analysis is that the public good is treated as a durable capital good subject to congestion we show how in the presence of congestion the effect of government investment on private capital formation involves a tradeoff between the degree of substitution between private and public capital in production and the degree of congestion both lump sum and distortionary tax financing are considered with this tradeoff being tightened in the latter case

perception of price when price information is costly evidence from residential electricity demand a bstract residential electricity consumption is an example of a good for which it is costly to determine marginal price since price changes with the quantity purchased according to multistep block rate schedules this paper investigates the effect of the price information problem on consumers price perceptions an alternative hypothesis of average price perception is tested against the marginal price postulate which assumes wellinformed consumers the model which includes a price perception variable allows the estimation of the price to which consumers actually respond the empirical results support the hypothesis that consumers respond to average price perceived from the electricity bill

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

environmental abatement and intergenerational distribution this paper employs an overlapping generations model to explore the impact of public abatement on private investment and the intergenerational distribution of welfare whereas public abatement benefits old generations in terms of non environmental welfare future generations gain most in terms of environmental welfare the overall benefits tend to be smallest for generations born at the time of the unanticipated policy shock public debt policy however can be employed to ensure that welfare gains are distributed more equally across the various generations such a policy implies that natural capital crowds out man made capital

price and income elasticities of residential water demand a meta analysis this article presents a meta analysis of variations in price and income elasticities of residential water demand meta analysis constitutes an adequate tool to synthesize research results by means of an analysis of the variation in empirical estimates reported in the literature we link the variation in estimated elasticities to differences in theoretical microeconomic choice approaches differences in spatial and temporal dynamics as well as differences in research design of the underlying studies the occurrence of increasing or decreasing block rate systems turns out to be important with respect to price elasticities the use of the discrete continuous choice approach is relevant in explaining observed differences

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

effect of price information on residential water demand microeconomic theory predicts that people decrease consumption when price increases the magnitude of the effect depending on price elasticity the law of demand however implicitly assumes that consumers know prices an assumption that is not always satisfied in markets with ex post billing when prices are not transparent elasticity estimates are potentially lower than their full information potential evidence of low price elasticity abounds in residential water demand studies limiting the effectiveness and desirability of using price signals as a conservation tool it is hypothesized that resident s sluggish response to price is partly due to the absence of price information on water bills differences in the informational content of bills are documented for the first time on the basis of sample bills collected from 383 utilities across the usa a standard aggregate water demand model is augmented with qualitative variables describing differences in billing information allowing such variables to a

measuring the income elasticity of water demand the importance of publication and endogeneity biases we present the first study that examines the effects of publication selection in the literature estimating the income elasticity of water demand paradoxically more affected by publication selection are the otherwise preferable estimates that control for endogeneity attempting to correct simultaneously for publication and endogeneity biases we find that the mean underlying elasticity is approximately 0 15 or less the result is robust to controlling for more than 30 characteristics of the estimates and accounting for model uncertainty the differences in the reported estimates are systematically driven by differences in the tariff structure regional coverage data granularity and control for temperature

public policies and convergence abstract this paper employs a dynamic framework to compare the effects of alternative government policies on convergence of industrialized economies to the technology frontier the government s instruments include facilitating private investment and education policy the latter enhances skills of heterogenous specialists and implies the decision on their respective shares the analysis distinguishes between an isolated policy of a single economy and coordinated policies of various countries which policy maximizes the speed of convergence is crucially affected by the economy s state of development a policy switch between the mentioned instruments while catching up may be preferable

infrastructure alternative government finance and stochastic endogenous growth abstract this paper constructs a stochastic version of an endogenously growing economy with a public good that raises the productivity of private capital we explore how growth and welfare are influenced by changes in the mean and variance of productive public spending under two alternative financing methods mixed money bond financing and wealth tax financing in addition to evaluate the differences between money financing and bond financing we consider mixed money bond financing under which a larger ratio of bonds to money is utilized to finance a given increase in public spending

public capital maintenance and congestion long run growth and fiscal policies abstract in this paper we study an endogenous growth model in which public maintenance expenditures affect the depreciation rate of public capital and the latter is subject to congestion we find that economies with low congestion in public infrastructure will require a threshold level of public capital maintenance for ongoing growth we also examine the fiscal implications of public capital maintenance policies and we find that the composition of public capital expenditures under congestion is a crucial determinant of optimal and growth maximizing fiscal policies the government can affect the return of public capital by re allocating public expenditures between new public investment and maintenance and hence avoid excessive taxation that is required under increasing congestion

the composition of government expenditure and its consequences for macroeconomic performance abstract this paper employs the intertemporal optimizing market clearing framework to compare the effects of government consumption expenditure and government infrastructure expenditure on macroeconomic adjustment and performance particular attention is focused on the time path of the capital stock and its adjustment to both permanent and temporary changes in government expenditure are considered we show how the effects of both forms of government expenditure on economic welfare can be broken down into 1 i a direct crowding out effect and 2 ii a second component which describes the intertemporal tradeoffs between the short run rate of capital accumulation and the resulting change in the capital stock

an intertemporal model of saving and investment this paper characterizes a market economy with infinitely long lived consumers and value maximizing firms which face costs of adjustment for capital the temporary equilibrium of this economy is similar to the short run equilibrium of standard macroeconomic models consumption is a function of wealth investment is related to the value of firms equilibrium between aggregate demand and aggregate supply is achieved by the endogenous adjustment of the sequence of current and future interest rates the dynamic behavior of output consumption and investment in this economy is the same as in an optimal growth model with adjustment costs the paper shows this equivalence and then uses it together with the equivalence of taxes to technological shocks to study the dynamic effects of fiscal policy
