nonmonetary effects of the financial crisis in propagation of the great depression this paper examines the effects of the financial crisis of the 1930s onthe path of aggregate output during that period our approach is complementary to that of friedman and schwartz who emphasized the monetary impact of the bank failures we focus on non monetary primarily credit related aspects of the financial sector output link and consider the problems of debtors as well as those of the banking system we argue that the financial disruptions of 1930 33 reduced the efficiency of the credit allocation process and that the resulting higher cost and reduced availability of credit acted to depress aggregate demand evidence suggests that effects of this type can help explain the unusual length and depth of the great depression this abstract was borrowed from another version of this item

rational heuristics expectations and behaviors in evolving economies with heterogeneous interacting agents we analyze the individual and macroeconomic impacts of heterogeneous expectations and action rules within an agent based model populated by heterogeneous interacting firms agents have to cope with a complex evolving economy characterized by deep uncertainty resulting from technical change imperfect information coordination hurdles and structural breaks in these circumstances we find that neither individual nor macroeconomic dynamics improve when agents replace myopic expectations with less naive learning rules our results suggest that fast and frugal robust heuristics may not be a second best option but rather rational responses in complex and changing macroeconomic environments jel c63 d8 e32 e6 o4

uncertainty risk and the financial crisis of 2008 the distinction between uncertainty and risk originally drawn by frank knight and john maynard keynes in the 1920s remains fundamentally important today in the presence of uncertainty market actors and economic policy makers substitute other methods of decision making for rational calculation specifically actors decisions are rooted in social conventions drawing from innovations in financial markets and deliberations among top american monetary authorities in the years before the 2008 crisis we show how economic actors and policy makers live in worlds of risk and uncertainty in that world social conventions deserve much greater attention than conventional ipe analyses accords them such conventions must be part of our toolkit as we seek to understand the preferences and strategies of economic and political actors

technical change and wage share fluctuations in a regime switching model abstract our model generates endogenous economic fluctuations from relationships between technical change employment and the submodel that determines wages and prices parameters of the wage price submodel which express a conflict between firms desires for greater markups on wages and workers desires for higher real wages are assumed to change when a critical level of employment is reached this switch in regime avoids explosive results and allows a great variety of results showing that economic fluctuations are consistent with a broad range of behavior and labor and product markets

are national accounts revisions harmful for historical comparisons revisions of national accounts affect economic analysis calling into question theoretical findings based on earlier data revisions to german national accounts have resulted in a markedly higher gdp in absolute terms and a lower volatility in macroeconomic production according to the revised data recessions have been less pronounced moreover less volatility in production has changed income accounts and above all reduced the fluctuations in property and entrepreneurial income the stylised fact of declining property and entrepreneurial incomes during recessions in west germany from 1970 to 1991 has vanished into thin air as a result of the revisions of 2002 and 2006

political aspects of innovation abstract political aspects that enhance but also undermine the positive transformational power of public innovation policies are examined as such this paper follows michal kalecki in his 1943 paper that identifies the political aspects which enhance and undermine the positive transformational power of keynesian full employment policies similarly this paper provides a policy framework that identifies what government and business support as innovation policies the role of innovation stems from schumpeter s long run perspective but incorporates the more dynamic cyclical short term and trend perspectives of kalecki this paper critiques the strategy of public innovation policy in general and derives policy implications

econometric analysis of bank lending and business cycles in south africa this article examines econometric relationships between bank lending and business cycle in south africa two long run economic relationships are hypothesized between total credit and the variables namely coincidental indicators spread between lending and borrowing rates money supply stock price index inflation and banking sector specific factors included in the model of these variables only coincident indicators changes in money supply as well as capital and reserve are found to exert some influence on short run total credit availability

an interdisciplinary model for macroeconomics macroeconomic modelling has been under intense scrutiny since the great financial crisis when serious shortcomings were exposed in the methodology used to understand the economy as a whole criticism has been levelled at the assumptions employed in the dominant models particularly that economic agents are homogeneous and optimizing and that the economy is equilibrating this paper seeks to explore an interdisciplinary approach to macroeconomic modelling with techniques drawn from other natural and social sciences specifically it discusses agent based modelling which is used across a wide range of disciplines as an example of such a technique agent based models are complementary to existing approaches and are suited to answering macroeconomic questions where complexity heterogeneity networks and heuristics play an important role

interpreting econometric evidence the behaviour of consumers expenditure in the uk abstract the dynamic models of consumers expenditure proposed by davidson et al 1978 and hendry and von ungern sternberg 1979 are re appraised in the light of hall s 1978 analysis of the empirical implications of the life cycle permanent income hypothesis in particular that the series for consumption should obey a random walk apart from trend in an attempt to reconcile the conflicting findings monte carlo experiments are used to demonstrate that if the davidson et al model were actually correct the hall model would appear to give a good description of the data and would probably not be rejected all the models are re estimated with new data for the uk and these data do reject a modified random walk specification in conclusion we discuss the issue of income exogeneity and comment on questions of model selection and interpretation

macroeconomic forecasting using pooled international data it has long been recognized that national economies are economically interdependent see e g burns and mitchell 1946 for evidence of comovements of business activity in several countries and zarnowitz 1985 for a summary of recent evidence recognition of such interdependence raises the question can such interdependence be exploited econometrically to produce improved forecasts of countries macroeconomic variables such as rates of growth of output and so forth this is the problem that we address in this article using annual and quarterly data for a sample of european economic community eec countries and the united states

monetary information and monetary neutrality abstract the monetary theory of business fluctuations in market clearing models constructed under the rational expectations assumption as advanced by lucas and others involves the idea that suppliers and demanders will typically misinterpret movements in the general level of prices as representing more or less favorable relative opportunities for real activities the present paper examines the consequences of agents possessing contemporaneous monetary information of a potentially noisy variety for the non neutrality of unanticipated monetary events within such an equilibrium business cycle model this modification of the information structure has the strong testable implication that real activity will be uncorrelated with contemporaneous monetary data

optimal taxation and fiscal constitution abstract assuming a world with excessive taxes the focuses of this paper are political mechanisms that ensure efficiency enhancing restraints on taxes in particular it is shown that supermajority requirements to approve tax increases as currently used in some us states is the means of attaining this objective their relationship to another such mechanism prevalent in earlier centuries that of franchise restrictions is discussed

what happens during recessions crunches and busts we provide a comprehensive empirical characterization of the linkages between key macroeconomic and financial variables around business and financial cycles for 21 oecd countries over the period 1960 2007 in particular we analyse the implications of 122 recessions 113 28 credit contraction crunch episodes 114 28 episodes of house price declines busts 245 61 episodes of equity price declines busts and their various overlaps in these countries over the sample period our results indicate that the interactions between macroeconomic and financial variables can play a major role in determining the severity and duration of a recession specifically we find evidence that recessions associated with credit crunches and house price busts tend to be deeper and longer than other recessions stijn claessens m ayhan kose and marco e terrones

a new approach to decomposition of economic time series into permanent and transitory components with particular attention to measurement of the business cycle abstract this paper introduces a general procedure for decomposition of non stationary time series into a permanent and transitory component allowing both components to be stochastic the permanent component is shown to be a random walk with drift and the transitory or cyclical component is a stationary process with mean zero the decomposition methodology which depends only on past data and therefore is computable in real time is applied to the problem of measuring and dating business cycles in the portwar u s economy we find that measured expansions and contractions are of roughly equivalent duration and that our dating of cyclical episodes tends to lead the traditional nber dating and to a lesser extent the growth cycle chronology of zarnowitz and boschan 1977

real wages in the business cycle and the theory of income distribution an unresolved conflict between theory and facts in mainstream macroeconomics the focus of this article is the recurring tension between mainstream macroeconomics and observed facts in connection with the difficult task of providing explanations of the business cycle consistent both with the traditional theory of income distribution and with the empirical evidence concerning the co movements of real wages and employment over the cycle the attempts to reconcile facts and theory have led to the continuous introduction of specific and arguably ad hoc hypotheses in contrast with the search for greater theoretical rigour claimed by the various streams of macroeconomic modelling subsequent to the neo classical synthesis in addition the specific assumptions introduced in the models or their implications are in turn often contradicted or at best not confirmed by subsequent empirical research it is suggested in the conclusions that the difficulty of keeping together in a simple and consistent framework theory and facts reflects the flawed theoretical foundations of mainstream theory

the concentration of capabilities and international trade over the course of the previous two decades political scientists have become increasingly interested in the relationship between international politics and global trade much of the literature on this topic centers on the effects of a hegemonic distribution of power on commerce hegemonic stability theorists argue that hegemony is a necessary condition for the existence of a liberal economic order and that in the absence of a hegemon a liberal international economy is particularly difficult to establish and maintain however a growing number of theoretical and empirical critiques have been leveled against the gemonic stability theory and the issue of whether hegemony helps shape patterns of global trade continues to be the topic of heated debate

business cycle models with endogenous technology this paper compares real and monetary business cycle models with and without endogenous technical change if technology is endogenous the properties of these models change significantly in particular both real and monetary models yield very similar output processes if growth is endogenous and changes in aggregate demand can result in permanent changes in productivity employment and output the effect of depreciation of technology is examined and the pattern of real wage movements over the cycle when money wages are fixed but technology is changing is briefly considered copyright 1990 by american economic association

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

learning while voting determinants of collective experimentation this paper combines dynamic social choice and strategic experimentation to study the following question how does a society a committee or more generally a group of individuals with potentially heterogeneous preferences experiment with new opportunities each voter recognizes that during experimentation other voters also learn about their preferences as a result pivotal voters today are biased against experimentation because it reduces their likelihood of remaining pivotal this phenomenon reduces equilibrium experimentation below the socially efficient level and may even result in a negative option value of experimentation however one can restore efficiency by designing a voting rule that depends deterministically on time another main result is that even when payoffs of a reform are independently distributed across the population good news about any individual s payoff increases other individuals incentives to experiment with that reform due to a positive voting externality

the intertemporal substitution model of labour market fluctuations an empirical analysis the paper uses two approaches to study whether aggregate fluctuations in employment and unemployment may be explained within a market clearing framework as intertemporal substitution in labour supply first log linear equations for labour supply and unemployment are estimated using a forecasting model to measure wage and price expectations second a utility function is used to derive and estimate an equation for labour supply as a function of the current real wage and consumption the influence of expected future real wages and interest rates is captured by the consumption variable the empirical results do not support the intertemporal substitution model

a real model of the world business cycle abstract in this paper a stochastic two country log linear infinite horizon model is used to analyze the generation and transmission of economic fluctuations across countries it is argued that following a country specific supply disturbance production interdependence and unitary elasticities in consumption and production are sufficient to generate comovements in aggregate economic activity investment and trade that are persistent over time and positively correlated across countries however the empirical analysis carried out for the usa japan germany and uk for the 1960 82 period suggests that common shocks rather than trade links are responsible for this pattern of comovements

international evidence on the historical properties of business cycles we contrast properties of real quantities with those of price levels and stocks of money for ten countries over the last century although the magnitude of output fluctuations has varied across countries and periods relations among real quantities have been remarkably uniform properties of price levels however exhibit striking differences between periods inflation rates are more persistent after world war ii than before and price level fluctuations are typically procyclical before world war ii and countercyclical afterward fluctuations in money are less highly correlated with output in the postwar period but are no more persistent than in earlier periods jel e32 e31

inefficiency in legislative policymaking a dynamic analysis this paper develops an infinite horizon model of public spending and taxation in which policy decisions are determined by legislative bargaining the policy space incorporates both productive and distributive public spending and distortionary taxation the productive spending is investing in a public good that benefits all citizens e g national defense and the distributive spending is district specific transfers e g pork barrel spending investment in the public good creates a dynamic linkage across policymaking periods the analysis explores the dynamics of legislative policy choices focusing on the efficiency of the steady state level of

okun s micro macro system a review article prices and quantities is the brilliant and disturbing last work of arthur m okun 1928 1980 for more than a decade okun was the foremost practitioner of macroeconomics in the united states his critical intelligence at both the theoretical and empirical ends of economics was unsurpassed these facts were virtually a manufacturer s warranty that the book whatever its argumentation and evidence would be significant we want to know what okun thought but this background was no guarantee of an important treatise and it must have taken some courage to venture a big theoretical work in an accessible style on urgent questions in fact okun has delivered a creative and virtuosic study in economic theory the book s contribution is to provide a complete description of an economy in which rational economic agents consider the distributional consequences of wage and price decisions the perspective adopted one which is winning growing favor of late is contract theoretic because they wish to economize on their costly transactions with one another people trade repeatedly with the same agent so trust and fidelity to understandings are important the ensuing analysis lodges some basic dissents from the informational expectational paradigm developed over the last score of years it is particularly stimulating and troubling on the main policy controversy of the decade the question of disinflation

heteroscedasticity or production risk a synthetic view two veins of literature namely production risk literature and stochastic frontier analysis are examined both fields are concerned of output variation the former due to exogenous shocks the latter due inefficiency by covering the literature from both the fields this review suggests that the concept of heteroscedasticity can be utilized to build a synthesis between these mainly separate branches of literature however the synthetic approach brings a challenge how to differentiate between different sources of output variation this challenge is identified as the main obstacle to meaningfully combine the two approaches

a re examination of the structure of unemployment this paper examines whether there has been a structural change in the sensitivity of unemployment to the business cycle in the united states the analytical framework of the investigation rests on two functional relationship between unemployment and economic activity introduced by thurow 1965 the results are conclusive in suggesting that there has been no change in this sensitivity over the period 1948 88 qi thus both total unemployment and various categories including sex race age and industry of unemployment are as sensitive to variations in the level of economic activity today as they were three decades ago

the importance of sectoral and aggregate shocks in business cycles the importance of sectoral and aggregate shocks in business cycles the theoretical literature on business cycles proposes numerous causes for their occurrence this paper attempts to measure the relative importance of aggregate whether real or nominal and sectoral factors in generating real economic fluctuations as well as to identify economic variables that are correlated with the various factors empirical results indicate that both aggregate and industry level factors are statistically significant in explaining variations in output with the aggregate factor being the most important some evidence is presented that links the aggregate factor with monetary variables i introduction prior to the keynesian revolution a great deal of theoretical and empirical research was conducted on the business cycle 1 with the acceptance of keynesian ideas the emphasis of macroeconomic research shifted from the study of business cycles to the study of macroeconomic policies required to reduce economic fluctuations this research program continued until the 1970s when oil price increases and the generally poor predictive performance of keynesian models caused many macroeconomists to question this research program as a result some economists such as robert lucas edward prescott and thomas sargent began to employ stochastic general equilibrium models to explain the main characteristics of the business cycle movements in output or real economic activity arise from the interaction of economic shocks and internal mechanisms which propagate their effects in this general framework which is based on the work of frisch 1933 and slutsky 1937 unanticipated disturbances or shocks are spread through the propagation mechanism resulting in serially correlated fluctuations in output while most theories of economic fluctuations can be fitted into this general framework there are disagreements over the form of the propagation mechanism and the source of the disturbances some models stress the role of aggregate demand shocks while other models such as the real business cycle models focus on real technological shocks such technological shocks may be sector specific and thus represent a set of disaggregate disturbances that cannot be viewed in the manner of aggregate shocks there is little agreement as to the main sources of disturbances knowledge of the relative importance of sector specific and aggregate shocks would be a significant development in theoretical work on business cycles this paper attempts to determine the relative importance of aggregate and disaggregate shocks in generating macroeconomic fluctuations it extends norrbin and schlagenhauf 1988 in a number of important ways the relative contribution of aggregate and sectoral shocks in generating real economic fluctuations is measured using disaggregated industrial production data which we believe is a better measure of real economic activity in addition we employ a more detailed disaggregation of manufacturing and mining industries covering a longer time period the robustness of the results is more carefully identified finally the methodology used to determine the relative importance of the shocks is substantially different in this paper 2 ii a time series model of disaggregate output the work of frisch 1933 and slutsky 1937 suggests that movements in output can be decomposed into an impulse effect and a propagation effect in this section we present a multivariate time series model of output for the united states this model is in the tradition of frisch s and slutsky s work and is sufficiently general to encompass most competing linear business cycle theories the model is developed at a disaggregate industry level allowing a propagation of output changes between industries in addition output fluctuations can arise from national industry group specific or idiosyncratic factors

facts and challenges from the great recession for forecasting and macroeconomic modeling this paper provides a survey of business cycle facts updated to take account of recent data emphasis is given to the great recession which was unlike most other postwar recessions in the united states in being driven by deleveraging and financial market factors we document how recessions with financial market origins are different from those driven by supply or monetary policy shocks this helps explain why economic models and predictors that work well at some times do poorly at other times we discuss challenges for forecasters and empirical researchers in light of the updated business cycle facts

commodity price fluctuations price dependent delays and nonlinearities as explanatory factors this paper develops a price adjustment model for a single commodity market with state dependent production and storage delays conditions for the equilibrium price to be stable are derived in terms of a variety of economic parameters when stability of the equilibrium price is lost a hopf bifurcation occurs giving rise to an oscillatory commodity price with a period between two and four times the equilibrium production storage delay

dynamic pivotal politics we analyze a dynamic extension of a parsimonious model of lawmaking in which preferences evolve over time and today s policy becomes tomorrow s status quo unlike in existing models of pivotal politics policy makers voting behavior depends on the institutional environment and on their expectations about future economic and political shocks relative to sincere voting the equilibrium behavior exhibits a strategic polarization effect which increases with the degree of consensus required by the institution the volatility of the policy environment and the expected ideological polarization of the future policy makers the equilibrium behavior also exhibits a strategic policy bias which works against any exogenous policy bias embedded in the voting rule our analysis implies that the existing literature underestimates the inertial effect of checks and balances and overestimates the impact of institutional biases such as fiscally conservative budget procedures

information as a substitute for inventories abstract in recent years the ratio of inventories to sales in north american manufacturing has fallen without the offsetting increases in unfilled orders or price variation that are predicted by some theoretical models the explanation offered here is that in the face of falling relative costs of communications firms will substitute information for inventories thereby allowing their production systems to absorb a greater part of demand shocks the implicit hypothesis that the demands for communications and inventories are therefore determined simultaneously is tested with data on canadian inventories and on telecommunications between canada and europe and is not rejected

adjustment lags versus information lags a test of alternative explanations of the phillips curve phenomenon reply it is perhaps a truism that without lags either in the adjustment of prices and wages or in the transmission of information about prices and wages there would be no business cycle but rather employment and output would follow presumably smooth paths determined by demographic factors capital accumulation and other long run processes the observation that movements in wages and prices are correlated with output and employment and the hypothesis that this phenomenon may be accounted for by adjustment lags in prices and wages are not new and certainly predate both the phillips 25 paper in 1958 and the keynesian revolution in macroeconomics for example irving fisher 5 6 presented both empirical and theoretical analyses along these lines more than a decade before publication of keynes general theory 15 in 1936 milton friedman s 8 analysis of the phillips curve phenomenon parallels fisher s thinking quite closely both emphasizing an hypothesized lag in factor prices behind final product prices attributed at least partially to the existence

faraway so close coupled climate and economic dynamics in an agent based integrated assessment model abstract in this work we develop an agent based model that offers an alternative to standard computable general equilibrium integrated assessment models iams the dystopian schumpeter meeting keynes dsk model is composed of heterogeneous firms belonging to capital good consumption good and energy sectors production and energy generation lead to greenhouse gas emissions which affect temperature dynamics climate damages are modelled at the individual level as stochastic shocks hitting workers labour productivity energy efficiency capital stock and inventories of firms in that aggregate damages emerge from the aggregation of losses suffered by heterogeneous interacting and boundedly rational agents the model is run focusing on a business as usual carbon intensive scenario consistent with a representative concentration pathway 8 5 we find that the dsk model is able to account for a wide ensemble of micro and macro empirical regularities concerning both economic and climate dynamics simulation experiments show a substantial lack of isomorphism between the effects of micro and macro level shocks as it is typical in complex system models in particular different types of shocks have heterogeneous impact on output growth unemployment rate and the likelihood of economic crises pointing to the importance of the different economic channel affected by the shock overall we report much larger climate damages than those projected by standard iams under comparable scenarios suggesting possible shifts in the growth dynamics from a self sustained pattern to stagnation and high volatility and the need of urgent policy interventions

the cyclical behavior of marginal cost and price the author examines the cyclical behavior of price marginal cost margins for u s manufac turing after 1956 short run marginal cost is markedly procyclical this is primarily due to procyclical overtime payments incurred beca use employment is not perfectly flexible in most industries output price fails to respond to the cyclical movement in marginal cost so price marginal cost margins are markedly countercyclical the res ults contradict business cycle theories that explain low production i n a recession by a high real cost of producing they support theories that explain low production in a recession by the inability of firms to sell their output copyright 1987 by american economic association

financing constraints and inventory investment a comparative study with high frequency panel data this study provides new evidence of the importance of financing constraints for explaining the dramatic cycles in inventory investment we compare the empirical performance of different financial variables coverage ratio cash stocks and cash flow used in previous research to test for the presence of financing constraints the comparison is undertaken in a common framework with an identical sample and high frequency quarterly firm panel data cash flow is much more successful than cash stocks or coverage in explaining the facts about inventory investment across firm size different inventory cycles and different manufacturing sectors

the role of international factors in the business cycle a multi country study abstract empirical research has been conducted on the various theories of the business cycle over many countries however very little research has attempted to undertake a multi country disaggregate investigation into the sources of output change this paper decomposes fluctuations in industry output in a particular country into 1 a nation specific shock 2 an industry specific shock 3 a common shock and 4 an idiosyncratic factor using a dynamic factor analysis state space approach the paper finds that the industry specific impulse explains a significant but small part of the variance of the forecast error this provides limited support for the disaggregated real business cycle paradigm

an inquiry into the sources of macroeconomic fluctuations abstract this paper attempts to decompose the sources of fluctuations in quarterly employment by industry and region into 1 an aggregate national shock 2 region specific shocks 3 industry specific shocks and 4 idiosyncratic factors the empirical analysis is motivated by a dynamic theory of the business cycle the empirical methodology is the engle watson dynamic mimic model implemented via the em algorithm the work is motivated as an attempt to compare empirically aggregate single factor theories of the cycle with real business cycle theories emphasizing industrial or regional shocks

bankruptcies firm size and unemployment a big bang theory of economic cycles this paper analyses the impact of bankruptcies on unemployment in an economy characterised by no substitutability of labour a computer simulation model is used to analyse its properties spectral analysis reveals the existence of cycles in unemployment it is found that average unemployment tends to be lower the more flexible are wages and interest rates provided both move anticyclically and the more rapid is the speed with which existing firms expand an economy characterised by small firms is found to be more stable with a tendency to a longer cycle than one characterised by large firms however given the assumptions we have made it is also likely to be characterised by higher average unemployment

the employment real wage relationship an international study the neoclassical and keynesian theories of employment both predict an inverse relationship between employment and real wages in the short run the observed correlation between employment and real wages however has usually failed to conform to this prediction dunlop 1938 and tarshis 1939 reported a positive correlation between real and money wages which given procyclical movement of money wages was interpreted as evidence against the theoretical prediction the statistical significance of these results was however challenged by ruggles 1940 and tobin 1948 more recent studies by kuh 1966 and bodkin 1969 failed to detect a significant relationship between real wages and employment these findings stimulated a series of contributions by solow and stiglitz 1968 barro and grossman 1971 1976 and others developing alternative models not apparently refuted by the evidence barro and grossman recast macro theory under the assumption that markets did not clear modigliani 1977 argued that the observed relationship between employment and real wages could be accounted for in an oligopolistic model of firm behavior thus both the competitive and equilibrium assumptions of the classical model were diagnosed as the sources of its apparent empirical refutation

political models of the business cycle should be revived political models of the business cycle have typically been ignored because they appear inconsistent with rational behavior and because empirical evidence is inconclusive this paper addresses the second issue demonstrating for u s real gnp unemployment and inflation that electoral cycles persistent patterns across electoral terms are significant but apparently only for republican incumbents and that partisan cycles persistent differences between parties are also significant these findings are consistent with the conjecture that a minority party is more constrained by electoral concerns whereas a majority party is freer to pursue partisan objectives

does anticipated monetary policy matter an econometric investigation a heated debate has arisen over the policy ineffectiveness proposition associate with the work of lucas sargent and wallace it postulates that anticipated aggregate demand policy will have no effect on business cycle fluctuations so that one deterministic feedback policy rule is as good as any other from the point of view of stabilizing the economy this paper develops a methodology for empirically analyzing rational expectations models displaying this neutrality result and then applies it to the important question of whether anticipated monetary policy matters to the business cycle

tests of equilibrium macroeconomics using contemporaneous monetary data abstract this paper uses contemporaneous monetary data to carry out econometric tests of the equilibrium approach to modelling the relation between monetary disturbances and macroeconomic fluctuations the theoretical analysis introduces into an equilibrium macroeconomic model the availability of preliminary data on current monetary aggregates and the process of accumulation of revised monetary data the econometric analysis tests two hypothesis derived from this extended model one hypothesis concerns the neutrality of perceived monetary policy the econometric results imply rejection of this hypothesis the other hypothesis concerns the non neutrality of errors in preliminary monetary data the econometric results fail to reject the contrary of this hypothesis these tests provide strong evidence against the reality of the equilibrium approach

an introduction to the theory of rational expectations under asymmetric information every good economics textbook contains the cliche that market prices provide signals which facilitate the allocation of resources to their best use in a world not subject to random shocks consumers and producers when faced with competitive prices need look no further than their own preferences or production technology to be able to make a decision they need give no thought to the tastes endowments or technology of other agents however in a world subject to random shocks this is no longer the case agents are faced with the problem of forecasting future states of nature and more importantly of forecasting the impact of these states on the actions of other agents rational expectations theories provide a model of how agents make those forecasts in a world subject to random shocks it will be the case that agents acquire or at least attempt to acquire information about the future realization of the shocks it will in general be the case that different agents have access to different information the fact that information is dispersed throughout the economy has the potential to cause a misallocation of resources relative to what would be the case if all agents knew everything an efficient allocation of resources will in general require the transfer of information from consumers who have some information about their future demands to producers who can take current actions to mitigate avoidable scarcities or surpluses though many classical and neo classical writers emphasize the informational role of prices the standard marshallian or walrasian model of competitive equilibrium does not involve prices transferring information across traders the purpose of this paper is to show that rational expectations models are radically different from walrasian models in an economy where traders have diverse information this is demonstrated by showing that unlike what occurs in a walrasian equilibrium of an economy with heterogeneous information if there is a complete set of insurance markets and utility is additively separable over time then there exists a rational expectations equilibrium which gives consumers the same allocation as if each consumer has access to all of the economy s information this implies that under the above assumptions a central planner with all the economy s information could not pareto dominate the competitive allocation achieved when traders have diverse information and rational expectations this paper makes no attempt to survey the literature on rational expectations the reader is referred to shiller 1978 barro 1981 for a survey of macroeconomics and rational expectations and radner 1980 for a survey of the microeconomics and mathematical theory of rational expectations this paper will however try to outline the evolution of the rational expectations concept from a notion of optimal forecasting to a virtually complete departure from the walrasian model of equilibrium the rest of this section is devoted to a discussion of pre rational expectations ideas

does growth vary over the business cycle some evidence from the g7 countries in this paper we analyse the dynamics of business cycles in the g7 countries our aim is to answer the question of whether growth varies in an absolute sense over the business cycle and hence to examine whether the simple two phase characterization downturn upturn is an appropriate description of the business cycle to study growth over the cycle we estimate single country equations and then a pooled regression that takes into account the important interactions of international business cycles the results confirm the steepness asymmetry of the growth cycles and show that growth varies systematically within upturns and downturns these are consistent with the notion of deepness asymmetry which implies that contractions are more pronounced in the later stages of a downturn whereas expansions are stronger immediately after troughs

some evidence concerning macroeconomic chaos abstract an empirical assessment of a linear stochastic perspective for canadian macroeconomic time series is presented the methods used are based on the mathematics of chaos present evidence suggests that low order deterministic chaos does not provide a satisfactory characterization of the data the absence of significant nonlinear structure for the investment and unemployment series is of particular note in light of past findings with american data the degree to which the use of a time trend can impose a pseudo structure on the data is illustrated

heterogeneous information and the theory of the business cycle the inability to observe the money supply and price level has been an essential ingredient of informational based equilibrium models of cycles here we assume these data are available but show that heterogeneous information about the productivity of capital can lead to a monetary theory of fluctuations in equilibrium each agent s investment depends on the difference between his own productivity and the perceived real rate in the presence of money demand shocks the nominal rate is noisy signal of the real rate this leads to greater fluctuations in output than if all agents had the same information

a nonparametric investigation of duration dependence in the american business cycle does the termination probability of a business expansion or contraction increase with age this question may be formally addressed by analyzing the nature of duration dependence in aggregate economic activity our null hypothesis is that there is no duration dependence which we test via intentionally nonparametric procedures we also argue that common notion of business cycle periodicity can be usefully interpreted in terms of whole cycle duration dependence we find some evidence for duration dependence in whole cycles and in prewar expansions but little evidence elsewhere

spending biased legislators discipline through disagreement this paper studies politicians who have a present bias for spending they want to increase current spending and procrastinate spending cuts we argue that legislators bias is more severe in economies with low institutional quality we show that disagreement in legislatures leads to policy persistence and that this attenuates the temptation to overspend depending on the environment legislators decisions to be fiscally responsible may either complement or substitute other legislator s decisions in economies with weak institutions politicians actions are strategic complements thus institutional changes that induce fiscal responsibility are desirable they generate a positive responsibility multiplier and reduce inefficient spending however in economies with better institutions the same institutional change would induce some legislators to free ride on others responsibility and may lead to more inefficient spending

nonlinear business cycle modelling abstract literature which employs nonlinearities to explain economic fluctuations commonly called business cycles is surveyed relaxation of the linearity assumption significantly increases the range of possible dynamic solution paths and introduces the possibility that business cycles are endogenously determined the dominant post war modelling strategy has been the frisch 1933 and slutsky 1937 inspired one of developing essentially log linear economic models which produce damped cycles or monotonic damping to propagate the energy provided by repeated random or autocorrelated shocks the cycle is exogenously driven since it would die out in the absence of shocks deterministic nonstochastic nonlinear models can produce a wide range of endogenous fluctuations including stable limit cycles growth cycles and chaotic output which have the appearance of random fluctuations further the same model can produce qualitatively different outputs according to starting and parameter values if the possibility of shocks to parameters is admitted then behaviour can change abruptly following shocks evidence on the existence of nonlinearities and chaos in macroeconomic time series is assessed and alternative approaches to modelling dynamic economic development related to the work of keynes marx schumpeter and shackle are discussed their ideas have not proved readily amenable to mathematical modelling but attempts to encapsulate some of them are reviewed
