intersectoral labor immobility sectoral comovement and news shocks sectoral comovement of output and hours worked is a prominent feature of business cycle data however most two sector neoclassical models fail to generate this sectoral comovement we construct and estimate a two sector neoclassical dynamic stochastic general equilibrium dgse model generating sectoral comovement in response to both anticipated and unanticipated shocks the key to our model s success is a significant degree of intersectoral labor immobility which we estimate using data on sectoral hours worked furthermore we demonstrate that imperfect intersectoral labor mobility provides a better explanation for the sectoral comovement than an alternative model emphasizing the role of labor supply wealth effects

micro and macro labor supply elasticities a reassessment of conventional wisdom the response of aggregate labor supply to various changes in the economic environ ment is central to many economic issues especially the optimal design of tax policies conventional wisdom based on studies in the 1980s and 1990s has long held that the analysis of micro data leads one to conclude that aggregate labor supply elasticities are quite small in this paper we argue that this conventional wisdom does not hold up to empirically reasonable and relevant extensions of simple life cycle models that served as the basis for these conclusions in particular we show that several pieces of conventional wisdom fail in the presence of human capital accumulation or labor supply decisions that allow for adjustment along both the extensive and intensive margin we conclude that previous estimates of small labor supply elasticities based on micro data are fully consistent with large aggregate labor supply elasticities jel d91 e24 j22

internal and external habits and news driven business cycles in many applications of habit persistence to macroeconomics it is of little significance whether habits are internal or external in this paper it is shown that the distinction between internal and external habits is important in a situation wherein a shock is news about the future an internal habit can be a source of news driven business cycles positive comovement in consumption labor investment and output from the news about the future whereas an external habit cannot

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

understanding expectation driven fluctuations a labor market approach this paper presents a uni ed analysis of neoclassical models that can generate expectation driven business cycles under anticipated future technology shocks or news shocks it shows that the ability or inability of various rbc models to generate positive comovement of aggregate variables hinges crucially on the structure of the labor market equilibrium the analysis provides a simple and intuitive guide to understanding the existing literature and to searching for new models that can explain the data under news shocks

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

indeterminacy aggregate demand and the real business cycle abstract we show that under indeterminacy aggregate demand shocks are able to explain not only aspects of actual fluctuations that standard rbc models predict fairly well but also aspects of actual fluctuations that standard rbc models cannot explain such as the hump shaped trend reverting impulse responses to transitory shocks found in us output cogley and nason am econom rev 85 1995 492 the large forecastable movements and comovements of output consumption and hours rotemberg and woodford am econom rev 86 1996 71 and the fact that consumption appears to lead output and investment over the business cycle indeterminacy arises in our model due to capacity utilization and mild increasing returns to scale

capacity utilization under increasing returns to scale abstract this paper overcomes an important objection against the empirical relevance of the benhabib farmer model as a potential account of actual business cycle fluctuations this is attributable to an elasticity effect and a returns to scale effect of capacity utilization these effects are closely related to the empirical puzzles that capital appears to play an insignificant role in explaining cyclical movements in output and that the estimated labor elasticity appears to be larger than labor s share due to these effects multiple equilibria and persistent fluctuations can easily occur in a growth model for externalities mild enough so that the aggregate labor demand curve is downward sloping analyses show that the propagation mechanism generated by capacity utilization under mild increasing returns is capable of explaining the periodic patterns of u s business cycles documented by watson journal of economic literature classification numbers e32 e22 c52

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

when can changes in expectations cause business cycle fluctuations in neo classical settings abstract it is often argued that changes in expectation are an important driving force of the business cycle however it is well known that changes in expectations cannot generate positive co movement between consumption investment and employment in the most standard neo classical business cycle models this gives rise to the question of whether changes in expectation can cause business cycle fluctuations in any neo classical setting or whether such a phenomenon is inherently related to market imperfections this paper offers a systematic exploration of this issue our finding is that expectation driven business cycle fluctuations can arise in neo classical models when one allows for a sufficiently rich description of the production technology however such a structure is rarely allowed or explored in macro models in particular we identify a multi sector setting and a setting with a costly distribution system in which expectation driven business cycles can arise

wealth varying intertemporal elasticities of substitution evidence from panel and aggregate data abstract this paper constructs and estimates a model of consumer preferences in which the intertemporal elasticity of substitution ies of consumption expenditure rises with the level of wealth the purpose of this paper is to measure the effect that systematic variation in the ies of poor and rich consumers has on the ies of aggregate consumption expenditure we find economically significant differences in the ies of poor and rich consumers in indian panel data on the consumption of individual households we also find economically significant differences in the ies measured in aggregate time series data for the u s and india

the spirit of capitalism and expectation driven business cycles abstract while news shocks are believed to be instrumental in explaining business cycles many existing models fail to predict a boom in consumption investment employment output and asset prices in response to good news about future productivity a model with the intrinsic desire for wealth is shown to generate the aforementioned responses a news driven boom is explained predominantly by an expansion of labor supply and is characterized by the falling real wage the simulated model not only captures well conventional business cycle statistics but also reproduces countercyclical real returns and hump shaped responses of hours and output to an unexpected technology shock

the time varying volatility of macroeconomic fluctuations we investigate the sources of the important shifts in the volatility of us mac roeconomic variables in the postwar period to this end we propose the esti mation of dsge models allowing for time variation in the volatility of the structural innovations we apply our estimation strategy to a large scale model of the business cycle and find that shocks specific to the equilibrium condition of investment account for most of the sharp decline in volatility of the last two decades jel c51 e32

aggregate returns to scale and embodied technical change theory and measurement using stock market data abstract we develop a new general equilibrium growth accounting framework that features increasing returns to scale imperfect competition and incorporates technological revolutions into the description of technical progress we propose a way to tell apart revolutionary changes in technology and incremental innovations using stock market data we use our framework to jointly estimate the overall embodied tfp change during 1953 1995 and the aggregate output elasticity we find that the it revolution raised the aggregate tfp level by about 20 we suggest a 1 09 1 11 range for the aggregate returns to scale

how does government spending news affect interest rates evidence from the united states abstract this study analyzes the effects of news shocks to u s government spending on interest rates especially long term interest rates and investigates the role of agents expectations in the propagation of government spending to interest rates using large bayesian vector autoregressive models with sufficient information we find that news about increases in government spending induce significant increases in both short and long term interest rates while the effects of government spending surprise shocks on interest rates are mixed and ambiguous government spending news shocks in the baseline model account for around 10 of the variance in forecast errors in long term interest rates which is much more important than government spending itself using empirical dynamic term structural models we further decompose increases in long term interest rates into changes in expectations of future monetary policy and changes in term premiums we find that an increase in the long term interest rate after a positive government spending news shock mainly reflects higher expected future short term interest rates which demonstrates the importance of the coordination between fiscal and monetary policy communication

an exploration into pigou s theory of cycles abstract this paper explores a theory of business cycles in which recessions and booms arise due to difficulties encountered by agents in properly forecasting the economy s future needs in terms of capital the idea has a long history in the macroeconomic literature as reflected by the work of pigou industrial fluctuation macmillan london 1926 the contribution of this paper is twofold first we illustrate the type of general equilibrium structure that can give rise to such phenomena second we examine the extent to which such a model can explain the observed pattern of u s recessions frequency depth without relying on technological regress we argue that such a model offer a framework for understanding elements of both the recent u s recession and of the asia downturns of the late 1990s

overaccumulation interest and prices an emerging view of business cycles from the news shock literature suggests that recessions may occur when agents depress their demand for new capital upon the realization that they have accumulated too much conditional on current information in this paper i use a new keynesian model with a financial accelerator to study the behaviour of interest and prices under both a technology boom bust driven by changes in expectation about tfp and a credit boom bust driven by changes in expectations about the efficiency of the financial sector while the two scenarios are similar in that they both lead to a run up and then sharp drop off in new capital and debt i show that the behaviour of interest and prices depends critically on the nature of the new shock driving the overaccumulation in particular the boom phase of the tfp boom bust is characterized by below trend inflation or deflation whereas that of the credit boom bust is characterized by above trend but low inflation in contrast inflation falls below trend in the bust phases of both i show that consistent with results elsewhere in the literature stricter inflationtargeting fails to pull the economy toward the efficient equilibrium during the boom phase of the tfp boom bust in contrast stricter inflation targeting pushes the economy closer to the flexible price response during the boom phase of the credit boom bust in both cases however conditional on realization of overaccumulation inflation targeting pulls the economy towards the flexible price equilibrium

news about aggregate demand and the business cycle abstract the plausibility of expectations driven cyclical fluctuations in an otherwise standard one sector real business cycle model with variable capital utilization and mild increasing returns to scale in production is examined due to a dominating wealth effect our model is able to generate qualitatively as well as quantitatively realistic aggregate fluctuations driven by news impulses to future consumption demand or government spending on goods and services when the economy is subject to anticipated total factor productivity or investment specific technology shocks the relative strength of the intertemporal substitution effect needs to be enhanced for our model to exhibit positive macroeconomic co movement and business cycle statistics that are consistent with the data

the demand for creative arts in regional victoria australia a healthy creative arts industry can contribute significantly to the economic and social fabric of a community unfortunately regional areas often suffer from a lack of supply and demand for the creative arts this article explores the demand for the creative arts in three regional locations in victoria australia using three broad dimensions of demand attitudes towards the arts frequency of participation in the arts and level of expenditure on the arts the analysis of demand patterns uses the general modelling approach of levy garboua and montmarquette 1996 as a basis and makes use of the ordered probit class of models for its statistical analysis the study confirms that individual levels of demand are contingent on a range of demographic characteristics and also identifies factors such as festival attendance and increased past creative arts expenditure as being important determinants of demand for the arts
