external economies and international trade redux comment recently in this journal grossman and rossi hansberg 2010 proposed a novel way to think about the implications of international trade in the presence of national external economies at the industry level instead of perfect competition and two industries grh assume bertrand competition and a continuum of industries grh conclude that the equilibrium is unique if transport costs are low that there is no trade for high transport costs and that there is no equilibrium in pure strategies when transport costs are intermediate in this note we reexamine the equilibrium analysis

unanticipated aggregate disturbances and tests of the life cycle consumption model several recent studies have used data on food consumption from the panel study of income dynamics psid to test t he rational expectations life cycle hypothesis against the alternative of prevalent liquidity constraints these tests invoke the rational expectations restriction that income forecast errors are independent of lagged information this restriction however applies only in a time series context it is possible that unanticipated macroeconomic disturbances cause forecast errors to be correlated with lagged information in a cross section of families the authors present evidence of such a correlation in the psid data show that this correlation biases previous tests of the life cycle model toward rejection and derive a proper test of the life cycle model using pa nel data copyright 1993 by mit press

variable returns to scale in production and patterns of specialization this paper discusses some trade and welfare implications of the two sector model based on increasing returns to scale irs in one industry and decreasing returns to scale drs in the other it has been shown by horst herberg and murray kemp that given homothetic production functions with irs in one industry and drs in the other the production possibilities frontier ppf is strictly concave to the origin near the irs axis and strictly convex to the origin near the drs axis while this result constitutes an important finding and is contrary to the general impression among economists even twelve years after the publication of herberg and kemp s paper no attempt has been made to analyze its implications for welfare and patterns of specialization in this paper i consider a simple twocommodity model with irs in one industry and drs in the other and discuss some interesting implications of variable returns to scale vrs first i demonstrate that in this model if a small open economy specializes completely in production it will do so in the drs commodity and not in the irs commodity as is generally believed second if at a given price ratio an internal production equilibrium exists a welfaremaximizing small open economy will never specialize completely in production even though the ppf exhibits decreasing opportunity costs over a part of its range third given output generated economies and diseconomies of scale welfare maximization for a small country requires a permanent tax subsidy scheme encouraging expansion of the irs industry and contraction of the drs industry finally in a two country model with identical tastes and technology across the countries free trade equilibrium may result in incomplete specialization by the exporter of the irs commodity and complete specialization by the exporter of the drs commodity in the course of the analysis i argue that tinbergen s formulation of frank graham s case for protecting the irs industry is incorrect i then present a possible reformulation of it in section i the basic production model is introduced in section ii the model is analyzed and in section iii it is argued that all the results continue to hold in the multifactor case

comparative advantage agglomeration economies and trade costs abstract this paper contributes to the theoretical research exploring the interface between comparative advantage locational fundamentals and agglomeration economies a simple model is developed which highlights costly trade of final outputs and of intermediates we derive the novel insight that the interaction between comparative advantage and agglomeration economies involves a fundamental tension which is intricately affected by trade costs a reduction of trade costs fosters the dispersive impact of comparative advantage in sectors governed by this force whilst the impact of agglomeration economies is enhanced by a fall in trade costs in industries where increasing returns prevail the key implication for international trade is that the relative wage between large and small economies is not only shaped by the primitive determinants of agglomeration economies and comparative advantage but also in a different way by trade costs the key implication for an economic geography setting where labor is mobile is that partial agglomeration emerges when agglomeration economies are strong relative to comparative advantage and this is more likely when trade costs are lower higher in industries governed by increasing returns comparative advantage the model provides a foundation for an urban system in which the larger city exhibits more diversity in production

models of inflation expectations formation a comparison of household and economist forecasts the recent appreciation of the critical role played by expectations of inflation in the behavior of macromodels has stimulated empirical studies of the formation of expectations by different groups time series survey data on expectations of inflation exist now for economists households and businesses these data have been used as independent variables in explaining wage behavior gordon 16 turnovsky and wachter 34 and de menil and bhatta 5 prices turnovsky and wachter 34 and wachtel 36 interest rates gibson 14 hendershott and van horne 19 pearce 30 and mishkin 27 and consumption wachtel 36 generally with a significant improvement in explanatory power they have also been used as dependent variables in attempts to determine how expectations are formed by gordon 15 mullineaux 28 jacobs and jones 20 and figlewski and wachtel 9 for the economist survey van duyne 35 for the household survey and leonard 23 and de leeuw and mckelvey 4 for businesses given their different levels of knowlege of economics and perspectives one might expect that the models used by the different groups to forecast inflation would

direct measurement of popular price expectations expectations are an important determinant of economic behavior the analysis of economic expectations however has suffered from inadequate measurement throughout the literature expectations have been treated as unobservable and have therefore been measured only indirectly the object of this paper is to develop and test a direct measure of the expectations of inflation a particularly critical economic variable a direct measure of inflationary expectations is here taken to be one constructed from a sample survey in which individuals are asked to state their expectations explicitly the paper focuses on a popular forecast of the rate of change of consumer prices in the forthcoming year as calculated from responses to the survey of consumer finances scf this measure is presented in section i the scf and others like it have existed for some time but a few recent studies notwithstanding most economists continue to regard survey measures as inherently unreliable their principal criticism is that the opinions an individual expresses

panel data modelling and the tax spend controversy in the euro zone this article attempts to differentiate between the debatable tax and spend spend and tax fiscal synchronization and institutional separation hypotheses in order to explore empirically the interplay between public expenditures and public revenues in the economic and monetary union emu member states for this purpose panel data models are derived to test the validity of the four hypotheses in emu countries a notable characteristic of this article is that the four hypotheses are tested by dividing emu countries into various subgroups and using disaggregated data for government expenditures and revenues seeking for the robustness of the empirical evidence the panel data methods of generalized two stage least squares gtsls and generalized method of moments gmm are accordingly applied to identify the relationship between public outlays and taxation receipts gtsls and gmm results strongly support the fiscal synchronization hypothesis implying that budget decision making is significantly influenced b

co integration and error correction models the temporal causality between government taxes and spending several interesting papers have recently considered whether government taxes granger cause government spending or vice versa the findings based on standard granger 6 causality tests are not consistent manage and marlow 10 conclude that when evidence of one way causality exists federal taxes granger cause federal spending while anderson wallace and warner 1 conclude that the evidence supports one way causality in the opposite direction ram 11 reexamining the issue concludes that taxes granger cause spending at the federal level but that spending granger causes taxes at the state and local level von furstenberg green and jeong 13 in another related article examine the tax and spend spend and tax causality issue using a more general vector autoregressive var model they introduce in addition to federal taxes and spending two economic variables the gnp gap and the inflation rate decompose federal spending into several categories and remove the effects of automatic stabilizers when appropriate they find little evidence that taxes granger cause spending and limited evidence that spending causes taxes a finding which corresponds most closely to that of anderson wallace and warner 1 our purpose is to reconsider the causality issue with the aid of co integration and errorcorrection modeling our analysis illustrates with a specific example how sources of causality can be neglected in standard granger causality tests moreover addressing the question of temporal causality between government taxes and spending provides insight as to how different policies might or might not help control the growth of government the results of our estimating various co integration and error correction models with quarterly data suggest bi directional causality between government taxes and spending both for the federal and state and local sectors this finding counters the conclusions of previous studies when annual data are used however our

testing the rationality of inflation forecasts from survey data another look at the src expected price change data this paper develops a unified econometric approach for testing the rationality of expectations from survey data series the paper employs the estimation techniques of hansen 1982 and eichenbaum hansen and singleton 1982 to conduct tests of unbiasedness efficiency and orthogonality for the src expected price change data in contrast to the existing literature the analysis takes careful account of serial correlation and conditional heteroskedasticity in the disturbance terms the results do not reject the properties of unbiasedness efficiency or othogonality for this survey data series copyright 1989 by mit press

do actions speak louder than words household expectations of inflation based on micro consumption data survey data on household expectations of inflation are routinely used in economic analysis yet it is not clear how accurately households are able to articulate their expectations in survey interviews we propose an alternative approach to recovering households expectations of inflation from their consumption expenditures we show that these expectations measures have predictive power for consumer price index cpi inflation they are better predictors of cpi inflation than household survey responses and more highly correlated with professional inflation forecasts except for highly educated consumers consistent with the view that more educated consumers are better able to articulate their expectations we also document that households inflation expectations respond to inflation news as measured by the unpredictable component of inflation predictions in the survey of professional forecasters the response to inflation news tends to increase with households level of education consistent with the existence of constraints on household s ability to process this information

clusters and comparative advantage implications for industrial policy abstract cases of industrial agglomeration or clusters arise in the presence of industry specific and local externalities also called marshallian externalities the standard argument is that such externalities may justify a policy of infant industry protection to allow and encourage clusters to emerge in this paper i explore this carefully and show that different policy implications emerge under a more realistic modeling of clusters in particular rather than distorting prices to promote clusters in advanced sectors that may exhibit strong clustering possibilities countries should focus instead on promoting clustering in current sectors which have revealed to have the strongest comparative advantage import substitution is not a proper way to achieve this

lag length selection and tests of granger causality between money and income one of the most widely accepred relationships in macroeconomics is the positive relationship between the rate of growth of the money supply and the rate of growth of income a diversity of opinion arises however with the attempt to identify a causal relationship between these variables while friedman and schwartz 1963 initiated the empirical investigation of money income causality sims 1972 made the most significant contribution to this literature with a practical application of the criterion developed by granger 1969 for identifying a causal relationship since the appearance of sims s approach and an alternative one advanced by sargent 1976 many researchers have applied these techniques to the investigation of the causal relationship between money and income l with two exceptions hsiao 1981 and mcmillin and fackler 1984 these researchers have arbitrarily chosen the lengths of their distributed lags the purpose of this paper is to test for granger causality between money and income this paper differs from previous work in that considerably more attention is focused on the effect of the lag specification on the test results in particular we investigate the extent to which rules of thumb arbitrary lag specifications and

survey measures of expected u s inflation of real interest rates and cash flows for decisions concerning investment expenditures international capital flows and exchange rate movements hinge in large part on expected real yield differentials across countries the federal reserve needs reliable measures of expected inflation to formulate and gauge the thrust of monetary policy in fact inflation expectations have become more important to the fed given the diminished stability of the link between the monetary aggregates and gdp expenditures since the early 1980s and the greater role which has been thrust upon expected real short term interest rates in the implementation of federal reserve policy the issue of rationality of inflation expectations that is the extent to which agents form expectations without making systematic mistakes in their beliefs about what inflation will be is important if inflation expectations are formed rationally labor and financial markets will strongly tend to neutralize the potential redistributive effects of inflation over time financial capital will flow efficiently within and across national borders moreover some of the stronger claims of new classical macroeconomics like the claim that only unexpected monetary policy actions will

endogenous comparative advantage gains from trade and symmetry breaking abstract similar countries often choose very different policies and specialize in very distinct industries this paper proposes a novel mechanism to explain policy diversity between similar countries from an open economy perspective i study optimal policies in a two country model where policies affect the determinants of trade patterns symmetric countries choose asymmetric policies in equilibrium if aggregate income is sufficiently convex in own policy such high social increasing return to policy despite constant returns to scale in production generate enough gains from trade to sustain policy diversity in equilibrium any asymmetric equilibrium is welfare improving compared to the common autarky optimum similarly a more asymmetric nash equilibrium pareto dominates a less asymmetric one as an application i consider a model in which the government s choice of education policy affects skill distribution and comparative advantage in this application the existence of an asymmetric nash equilibrium in education policy requires that the elasticity of the education cost of agents with respect to skill is relatively low

wage growth and the inflationary process a reexamination the nature of the relationship between wage growth and inflation has long been the subject of ongoing debate the expectations augmented phillips curve theory contends that the two variables are mutually causal however the original wage type phillips curve model argues it is inflation that causes wage growth rather than vice versa the price markup scheme holds an opposite view and asserts that wage growth plays an independent causal role in the inflationary process of course other theories e g the monetarist deny the presence of any reliable linkage between wages and prices researchers have also expended enormous effort attempting to investigate empirically the relationship between wage growth and inflation but with mixed results for example mehra 24 and ashenfelter and card 1 report results suggesting a bidirectional causality barth and bennett 2 and stein 37 38 find causality running from prices to wages without feedback while shannon and wallace 34 and hill and robinson 19 report results showing causality only in the reverse direction from wages to prices still gordon 11 bazdarich 4 batten 3 and mehra 27 find no causal linkage between the two variables clearly such remarkably mixed evidence is unfortunate in light of the profound implications that the precise wage price relationship may have for economic and public policy a more recent and quite interesting study is that of mehra 28 mehra employed the technique of cointegration and error correction modelling on u s quarterly data for the period 1959 1 1989 3 he concluded that inflation and wage growth are cointegrated implying that their long run movements are correlated as the expectations augmented phillips curve theory predicts however contrary to this theory and in accordance with the original wage type phillips curve view mehra argued that the inflation wage growth long run correlation is primarily the outcome of the former causing the latter mehra s model encompasses three basic variables namely prices p productivity adjusted wages w and an output gap proxy g he tested each of the three variables in logs for the presence of unit roots finding evidence of two unit roots in p and w but a single unit root in g mehra then examined cointegration of the two variables having two unit roots p w his re

causation spending and taxes sand in the sandbox or tax collector for the welfare state causal relations between federal expenditure and taxation are analyzed using an approach based on the invariance of econometric relationships in the face of structural interventions institutional evidence for interventions or changes of regime combined with econometric tests for structural breaks are used to investigate the relative stability of conditional and marginal probability distributions for each variable the patterns of stability are the products of underlying causal order the authors find two distinct causal structures operating in the postwar era before the mid 1960s taxes appear to cause spending after the late 1960s taxes and spending are causally independent copyright 1992 by american economic association

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

have large budget deficits caused rising trade deficits for the united states the 1980s have been years of both large and unprecedented trade deficits as well as massive federal budget deficits the trade deficit rose from 25 billion in 1980 to 124 billion in 1985 during this same period federal budget deficits soared from 74 billion in 1980 to more than 212 billion in 1985 it is widely believed that the u s trade deficit rose mainly because of the skyrocketing federal budget deficit presenting such a view are for example hutchison and pigott 25 hutchison and pyle 26 clark 11 modigliani 30 and aschauer 2 besides economists many labor unions i e afl cio and official government documents see the economic report of the president particularly of 1984 have all shared similar views the issues involved have important policy implications suppose that the basic reason for rising trade deficits is indeed the escalating federal budget deficit in this case policy makers may focus on curtailing the budget deficit in order to resolve the trade deficit problem that has adversely affected several sectors such as manufacturing industries and agriculture however if such a view concerning the causal role of the budget deficit is incorrect then reductions in the federal budget deficit may not resolve the trade deficit dilemma and moreover attention will be diverted from more relevant and urgently needed policy options 6 the purpose of this paper is to empirically investigate the conventional argument that high federal budget deficit has been the prime cause of the escalating u s trade deficit finding only partial empirical evidence to support it in section ii i argue that most of previous studies in this area appear flawed by a methodological error rendering their tests unreliable for discriminating between a number of equally plausible hypotheses section iii describes the data and methodology used in the paper section iv presents the empirical results section v summarizes and concludes the paper

inflation expectations and behavior do survey respondents act on their beliefs we compare the inflation expectations reported by consumers in a survey with their behavior in a financially incentivized investment experiment the survey is found to be informative in the sense that the beliefs reported by the respondents are correlated with their choices in the experiment more importantly we find evidence that most respondents act on their inflation expectations showing patterns consistent with economic theory respondents whose behavior cannot be rationalized tend to have lower education and lower numeracy and financial literacy these findings help confirm the relevance of inflation expectations surveys and provide support to the microfoundations of modern macroeconomic models

a theoretical explanation of some stylized facts of economic growth this paper presents a three good two country general equilibrium model that is consistent with several stylized facts of economic growth the three goods are manufactures agriculture and services manufactures are subject to economies of scale the model predicts that services a nontraded good must be more expensive in the country with higher per capita income it also shows that as per capita income increases we should expect the productivity in commodities relative to services to rise the model is able to generate many other stylized facts of economic growth

government spending and taxation what causes what in the past few years as federal deficits have risen to high nominal levels economists have argued about the effect that raising taxes ostensibly to reduce deficits might have on government spending some economists including milton friedman have argued that raising taxes will simply lead to more spending others including james buchanan and richard wagner have said that the high deficits themselves have been responsible for the growth of federal spending and that if that spending had to be financed completely by direct taxes people would demand that the federal government spend less a third group led by robert barro says that increased taxes and borrowing are results of increased government spending in section ii we briefly review various hypotheses about the relationship between federal government spending and revenues section iii describes the testing procedure used to discriminate between these hypotheses the results of four tests are presented in section iv section v contains a summary and major conclusions to foreshadow what follows we find no evidence that higher real federal taxes today lead to either higher or lower federal spending tomorrow on the other hand we find strong evidence that higher spending now will lead to higher taxes later our results support a view of the world in which the political system somehow determines how much to spend and then looks for revenue sources to finance that level of spending including direct taxation borrowing and money creation we also find evidence that real federal revenues are positively affected by real gross national product gnp real federal spending also rises with real gnp but it appears to be independent of the rate of inflation

is inflation sticky abstract new keynesian sticky price models predict that monetary policy can affect real variables however they also predict that inflation can be reduced without depressing output or employment in fact bringing down inflation is costly presenting a challenge to the new keynesian model two departures from the new keynesian model predict costly disinflation one assumes sticky inflation rather than sticky prices while the other assumes less than perfectly rational expectations taking into account information from surveys of inflation expectations i find the evidence suggests that inflation is not sticky and that inflation expectations are less than perfectly rational

monetary policy for inattentive economies we offer a contribution to the analysis of optimal monetary policy we begin with a critical assessment of the existing literature arguing that most work is based on implausible models of inflation output dynamics we then suggest that this problem may be solved with some recent behavioral models which assume that price setters are slow to incorporate macroeconomic information into the prices they set a specific such model is developed and used to derive optimal policy in response to shocks to productivity and aggregate demand optimal policy is price level targeting base drift in the price level which is implicit in the inflation targeting regimes currently used in many central banks is not desirable in this model when shocks to desired markups are added optimal policy is flexible targeting of the price level that is the central bank should allow the price level to deviate from its target for a while in response to these supply shocks but it should eventually return the price level to its target path optimal policy can also be described as an elastic price standard the central bank allows the price level to deviate from its target when output is expected to deviate from its natural rate

on error correction models specification interpretation estimation abstract error correction models ecms have proved a popular organising principle in applied econometrics despite the lack of consensus as to exactly what constitutes their defining characteristic and the rather limited role that has been given to economic theory by their proponents this paper uses a historical survey of the evolution of ecms to explain the alternative specifications and interpretations and proceeds to examine their implications for estimation the various approaches are illustrated for wage equations by application to uk labour market data 1855 1987 we demonstrate that error correction models impose strong and testable non linear restrictions on dynamic econometric equations and that they do not obviate the need for modelling the process of expectations formation with the exception of a few special cases both the non linear restrictions and the modelling of expectations have been ignored by those who have treated ecms as merely reparameterisations of dynamic linear regression models or vector autoregressions

inflationary expectations and rationality revisited abstract we find evidence indicating cointegration between each of three survey measures of inflation expectations and actual inflation using johansen s framework we confirm weak form rationality for each survey and estimate significant speeds of adjustment for both inflation and inflation expectations

tax and spend or spend and tax an inquiry into the turkish budgetary process for resolving the budget deficit problem some economists have advocated spending cuts while others support either tax increases or tax cuts this paper investigates the interrelationship between the two fiscal variables for turkey using bivariate and multivariate cointegrating models the engle granger and johansen tests consistently support the existence of one nonzero cointegrating vector representing a stable long run relationship between government spending and revenues in turkey furthermore the multivariate error correction model suggests that taxes unidirectionally granger cause negative changes in spending in accordance with the buchananwagner hypothesis thus from the perspective of policy making and the deficit solution debate raising taxes in turkey is perhaps the optimal solution to the current budget deficit predicament contemporary economies perhaps without exception have been plagued with huge and escalating government budget deficits these deficits are expected to have adverse economic consequences including high real interest rates slow capital formation and high unemployment rates moreover to the extent that the deficit is financed through the issuance of government bonds the recurrent large deficits have further worsened the public debt problem which threatens the well being of numerous countries both developed and developing therefore researchers and policymakers have expended enormous efforts attempting to analyze the deficit problem and to suggest ways to resolve it some for example advocate cuts in government spending rather than tax increases as the optimal solution to the deficit dilemma they reason that governments often spend all that they receive in taxes and perhaps much more under this line of reasoning raising taxes would simply induce more spending leaving the deficit unchanged or even higher others however deny this implied tax and spend nexus and argue that it is taxes that adjust gradually to spending under this latter scenario tax increases will not lead to higher spending and thus could be used as an effective deficit cutting measure along with spending cuts still other researchers posit that changes in spending and taxes could occur simultaneously therefore focusing on one component of the government budget while ignoring the interdependence with the other component would have an ambiguous overall effect on the deficit

expectations heterogeneous forecast errors and consumption micro evidence from the michigan consumer sentiment surveys the household data underlying the michigan index of consumer sentiment are used to test the rationality of consumer expectations and their usefulness in forecasting expenditure the results can be interpreted as characterizing the shocks that hit different types of households over time expectations are found to be biased and inefficient at least ex post people underestimated the disinflation of the early 1980s and the severity of recent business cycles people s forecast errors are also systematically correlated with their demographic characteristics in part because of time varying group level shocks further sentiment helps forecast consumption growth some of this rejection of the permanent income hypothesis is due to the systematic demographic components in forecast errors

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

aggregate consumption and saving in the postwar united states two commonly used sources of aggregate expenditure data are personal consumption expenditures in the national income and product accounts and the consumer expenditure surveys administered by the bureau of labor statistics we adjust both data sources to incorporate the service flows from owner occupied housing and other consumer durables a comparison of the two estimates of aggregate expenditure reveals that the differences between the two data sets have been growing over time by 1989 the level of aggregate expenditure in the national accounts exceeds that reported in the consumer expenditure surveys by 1224 billions less than half of this difference can be attributed to definitional differences in the two data sources

on the difficulty of eliminating deficits with higher taxes some canadian evidence government budget deficits have increased along with government revenues from direct and indirect taxation both in absolute amounts and as a share of national income in canada as well as in several other countries especially since the 1960s this phenomenon also has coincided particularly since 1980 with skepticism over the notion that government deficit spending stimulates economic growth and employment instead many now expect deficits to produce negative effects on economic activity including high real interest rates reduced real capital formation and production increased unemployment and possible long term inflation 2 these expectations have produced a near concensus on the need to reduce government budget deficits but not on the means of achieving that goal some advocate reductions in government spending as the optimal solution while others call for increases in taxation to raise revenue although either policy in principle may achieve the same result for the deficit they arise from different theories of the determinants of government spending in particular those who advocate expenditure cuts suggest that increased taxation would increase government spending more than it would reduce the deficit arguing that there is a causal direction from increased tax revenues to increased government expenditures although the taxation spending causality hypothesis has assumed increased prominence over the last decade 3 little statistical testing has been done for canada studies by manage and marlow 18 and ram 21 lend support to the argument that expenditures are more responsive to revenues than the reverse on the basis of u s data indeed ram s work contradicts the earlier conclu

friedman tax cuts vs buchanan deficit reduction as the best way of constraining government i introduction both milton friedman and james buchanan believe that the federal government spends more than can be justified on the basis of economic efficiency both also agree that the reason for excessive government spending is that the political process allows people to realize the benefits from government spending without fully paying the cost of that spending but friedman and buchanan are in apparent disagreement on the effectiveness of alternative approaches at constraining government by considering friedman and buchanan s apparent disagreement at the level of fiscal policy it is possible to better understand their agreement at the level of constitutional policy milton friedman has argued that a reduction in taxes and tax revenues with an increase in the budget deficit serves the useful function of restraining government spending for example friedman 1982 60 61 has written i want to cut tax rates but if the lafferites were correct in the extreme form that a particular cut in taxes increased revenue then my conclusion would be that we hadn t cut tax rates enough because what i want to cut is government revenue that s what feeds government spending what they the big spenders want is to increase taxes so they will have more money to spend and won t have to cut spending the triumph in my opinion of the tax cutting policy that president reagan has been following is that he has made the big spenders talk on his terms for the first time they have to face up seriously to cutting spending 1 in contrast james buchanan argues that reducing taxes and increasing debt financing lowers the perceived cost of government spending and consequently increases government spending for example buchanan and wagner 1977 138 139 state the replacement of current tax financing by government borrowing has the effect of reducing the perceived price of government goods and services with the result that taxpayers increase their demands for such goods and services preferred budget levels will be higher and these preferences will be sensed by politicians and translated into political outcomes in discussing the economic policy of the reagan administration william niskanen who was a member and acting chairman of the president s council of economic advisers during the reagan presidency takes note of the conflicting views of friedman and buchanan according to niskanen 1988 109 milton friedman promoted a view that tax rates should be reduced at every opportunity believing that the resulting increase in the deficit would increase pressure to reduce federal spending james buchanan expressed a directly contrary view that a tax increase would reduce spending by increasing the perceived price of government services to the current voters niskanen continues by expressing his leanings toward the buchanan view a leaning based on his own research niskanen 1978 he points out however that recent empirical work is inconclusive with some supporting friedman s position and some supporting buchanan s niskanen 1988 109 concludes his discussion of the difference of opinion between friedman and buchanan by observing that economists and politicians unfortunately do not yet share a clear understanding of these taxing spending and budget deficit relations a simple model of taxation spending and deficit determination provides a framework for examining systematically the conflict between friedman and buchanan it makes clear that the relationships among these variables cannot be determined by empirical investigation alone because both the friedman and buchanan positions emerge as special cases of a more general model it is not surprising that empirical studies can be found to support either position indeed we demonstrate that historic episodes exist which support the positions of both men ii the model political decisions like market decisions are made in response to benefits and costs

real stock prices and the long run money demand function evidence from canada and the usa abstract this paper investigates the relationship between stock prices and the long run money demand function in canada and the usa during the post wwii period 1955 1989 the empirical investigation is conducted by means of the johansen method of cointegration and the error correction modelling strategy results show that stock prices play a significant role in the determination of stationary long run real m1 and real m2 demand functions in both countries the direction and magnitude of the role of stock prices depends upon the definition of the money and the country error correction results provide evidence of causality between the real money stock and the determinants of the money demand including real stock prices

policy regime changes and monetary expectations testing for super exogeneity abstract the super exogeneity status for weekly u s monetary expectations structure is examined the incomplete structure of the proposed model requires the use of an incidental parameter which is approximated by a linear function of certain instruments a super exogeneity test within the instrumental variables framework examines whether distributional changes stemming from the regime shifts affect the error correction parameter in the expectations structure under the assumption that the variance of the error correction term is constant the data evidence is found to reject super exogeneity

new keynesian economics and the phillips curve models with sticky prices are an important part of new keynesian economics the author shows that several of the new keynesian models imply a formulation that is similar to the expectations augmented phillips curve of milton friedman and edmund phelps he then presents new estimates of the new keynesian phillips curve the author uses two proxies for price expectations survey based measures and an econometric based measure originally developed by bennett mccallum 1976 overall the results are consistent with the model but the survey based results are more precise suggesting that the surveys may be better measures of actual expectations copyright 1995 by ohio state university press

biases in macroeconomic forecasts irrationality or asymmetric loss empirical studies using survey data on expectations have frequently observed that forecasts are biased and have concluded that agents are not rational we establish that existing rationality tests are not robust to even small deviations from symmetric loss and hence have little ability to tell whether the forecaster is irrational or the loss function is asymmetric we quantify the exact trade off between forecast inefficiency and asymmetric loss leading to identical outcomes of standard rationality tests and explore new and more general methods for testing forecast rationality jointly with flexible families of loss functions that embed quadratic loss as a special case an empirical application to survey data on forecasts of nominal output growth demonstrates the empirical significance of our results and finds that rejections of rationality may largely have been driven by the assumption of symmetric loss

policy designs in a dynamic model of infant industry protection abstract this paper takes the neoclassical infant industry model allows agents to respond to future expectations and reveals previously unexplained relationships between protection and outcome policy which projects to protect the industry until international competitiveness may not necessarily succeed consistent to the mixed empirical evaluations to guarantee success protection has to last longer however for success to be an equilibrium protection can last shorter decline after take off is also an equilibrium when adjustment speed is bounded increasing the protection rate is not isomorphic to decreasing its duration in policy design adjustment speed critical industry scale and policy duration are all relevant

exogenous oil supply shocks how big are they and how much do they matter for the u s economy abstract the paper proposes a new measure of exogenous oil supply shocks the timing the magnitude and the sign of this measure may differ greatly from current state of the art estimates it is shown that only a small fraction of the observed oil price increases during oil crisis periods can be attributed to exogenous oil production disruptions exogenous oil supply shocks cause a sharp drop of u s real gdp growth after five quarters rather than an immediate and sustained reduction in economic growth and a spike in cpi inflation after three quarters overall exogenous oil supply shocks made remarkably little difference for the evolution of the u s economy since the 1970s although they did matter for some historical episodes

macroeconomic expectations of households and professional forecasters economists have long emphasized the importance of expectations in determining macroeconomic outcomes yet there has been almost no recent effort to model actual empirical expectations data instead m acroeconomists usually simply assume that expectations are rational this paper shows that while empirical household expectations are not rational in the usual sense expectational dynamics are well captured by a model in which households views derive from news reports of the views of professional forecasters which in turn may be rational the model s estimates imply that people only occasionally pay attention to news reports this inattention generates stickyness in aggregate expectations with important macroeconomic consequences

the causal relation between federal expenditures and receipts federal expenditures have consistently exceeded federal revenues since 1970 in fact the federal government has seen a surplus in only five years since 1950 the symptoms of such fiscal imbalance are of course budget deficits while budget deficits are nothing new in u s history the recent and projected size of the deficit during peacetime nonrecessionary years has been the cause of much concern to academics the news media and politicians this preoccupation with federal deficits has produced a variety of policy proposals to deal with them

permanent income current income and consumption evidence from two panel data sets in this article i estimate euler equations that is the first order conditions of the consumers maximization problem using data from two data sets consumption data are taken from the consumer expenditure survey income data are taken from the panel study of income dynamics because the data for the estimation come from two samples i use a generalization of the instrumental variables estimator the two sample instrumental variables estimator i find evidence that consumption is excessively sensitive to predictable income growth the estimates of the coefficient of excess sensitivity for three consumption measures range from 2 to 5

tax and spend spend and tax or fiscal synchronization new evidence for ten countries cointegration and vector autoregression are used to test the tax and spend spend and tax and fiscal synchronization for ten countries using annual time series data over the period 1951 to 1996 three of them are part of the newly industrialized countries of asia south korea taiwan and thailand and seven are industrialized countries australia canada japan new zealand south africa uk and the usa this paper includes gdp as a control variable into the model like baghestani and mcnown 1994 ross and payne 1998 and koren and stiassny 1998 the johansen 1988 and johansen and juselius 1990 cointegration test results indicate that these three variables are cointegrated with two cointegrating vectors for south korea one vector for australia canada south africa taiwan uk and the usa and no vector for japan new zealand and thailand the results from granger causality tests suggest unidirectional causality running from revenues to spending supporting the tax and spend hypoth

the intertemporal elasticity of substitution an exploration using a us panel of state data this paper uses state level consumption data to estimate the intertemporal elasticity of substitution of consumption ies in contrast to the results of hall 1988 and campbell and mankiw 1989 we provide evidence indicating that the ies is significantly different from zero and probably close to one since inference about the ies in the context of the standard euler equation is problematic as a result of mis specification bias we cast most of our discussion in the context of the framework developed by campbell and mankiw this modifies the euler equation in that a fraction of agents simply consume their income the use of panel data to examine the relationship between interest rates and consumption growth has two advantages first we achieve a significant increase in precision which in particular allows us to rule out a zero ies second we can use the panel aspect of the data to bypass asset return measurement problems in particular we identify a common time component in expected consumption growth that is associated with movements in interest rates when the ies is positive

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

income variance dynamics and heterogeneity recent theoretical work has shown the importance of measuring microeconomic uncertainty for models of both general and partial equilibrium under imperfect insurance in this paper the assumption of i i d income innovations used in previous empirical studies is removed and the focus of the analysis is placed on models for the conditional variance of income shocks which is related to the measure of risk emphasized by the theory we first discriminate amongst various models of earnings determination that separate income shocks into idiosyncratic transitory and permanent components we allow for education and time specific differences in the stochastic process for earnings and for measurement error the conditional variance of the income shocks is modelled as a parsimonious arch process with both observable and unobserved heterogeneity the empirical analysis is conducted on data drawn from the 1967 1992 panel study of income dynamics we find strong evidence of sizeable arch effects as well as evidence of unobserved heterogeneity in the variances

turkish budget deficit sustainability and the revenue expenditure nexus the sustainability of the turkish budget deficits as well as the dynamics of government revenues and expenditures in controlling the size of the deficit is examined using annual data from 1968 to 2004 the findings support the existence of a long run relation between government revenues and expenditures once allowance is made for an unknown structural break however the size of the slope parameter is significantly less than one suggesting that the government might face difficulties in financing its future debt with respect to the revenue expenditure nexus the empirical evidence is favourable to the tax spend hypothesis through the error correction term in the expenditures equation finally there is no evidence of asymmetries in the adjustment process in either the threshhold autoregressive or momentum threshold autoregressive specifications of the budgetary adjustment process

models of inflation expectations formation a comparison of household and economist forecasts comment in the third section of his paper models of inflation expectations formation a comparison of household and economist forecasts gramlich 1983 presents statistics suggesting that two survey measures of inflation expectations are biased and inefficient in this comment we show that the main results presented in his table 1 are generated using a misspecified model when the specification error is corrected we find that the michigan survey of household inflation expectations passes the standard tests for unbiasedness and weak tests for efficiency 1 however there remains doubt about the properties of the inflation expectation series derived from the livingston survey of professional economists 2 the particular results we review were presumably generated from ordinary leastsquares ols estimation of the following equation equation 2 in gramlich
