investment spikes new facts and a general equilibrium exploration abstract using plant level data from chile and the u s we show that investment spikes are highly pro cyclical so much so that changes in the number of establishments undergoing investment spikes the extensive margin account for the bulk of variation in aggregate investment the number of establishments undergoing investment spikes also has independent predictive power for aggregate investment even controlling for past investment and sales we re calibrate the thomas 2002 is lumpy investment relevant for the business cycle journal of political economy cx 508 534 model that includes fixed costs of investing so that it assigns a prominent role to extensive adjustment the recalibrated model has different properties than the standard rbc model for some shocks

estimation of a taiwan monetary reaction function with time varying parameters this paper employs a nonlinear kalman filter to examine the time varying responses of taiwan s monetary policy in the presence of a limited dependent variable the kalman filtered parameters reveal that the responses are not constant but change over time furthermore a counter cyclical reaction function is identified and a stronger than usual discretionary policy during the recessions is found

fixed costs and long lived investments abstract fixed costs models are difficult to analyze because they feature non degenerate time varying distributions of capital across firms if investments are sufficiently long lived however then the cross sectional distribution of capital holdings has virtually no bearing on the equilibrium and the aggregate behavior of fixed cost models is essentially identical to neoclassical models the findings are due to a near infinite elasticity of investment timing for long lived investments a feature shared by fixed cost models and neoclassical models irrelevance results found in numerical studies of fixed cost models are not parametric special cases but instead are fundamental properties of models with long lived investment goods

the costs of hiring skilled workers the shape of adjustment costs in factor demand has been a matter of controversy for quiet some time while some researchers assume quadratic adjustment costs i e that it becomes increasingly expensive to recruit workers in a given time period others believe that there are economies of scale in recruitment surprisingly there is hardly any evidence so far on the shape of hiring costs based on microeconomic data in this paper we estimate the functional form of hiring costs in the theoretical framework of a generalized model of monopsony using both parametric and nonparametric estimation techniques we find strong evidence in favor of diseconomies of scale in recruiting skilled workers our results indicate that the labor market is monopsonistic

does the federal reserve respond to errant money growth evidence from three monetary regimes this paper tests the hypothesis that the federal reserve responds to deviations between actual and targeted money growth with a corrective adjustment in their policy instrument the authors divide the sample period of 1975 87 into three monetary regimes their results suggest that the fed responded to errant money growth in the pre 1979 and the 1979 82 subperiods however the authors find no evidence that the fed responded to errant money growth in the post 1982 subperiod these results yield some insights into the source of the money supply announcement puzzle by lending support for what has been termed the policy anticipation effect copyright 1992 by ohio state university press

time varying response of monetary policy to macroeconomic conditions we reject the hypothesis that the federal reserve s response to the macroeconomy over the period of 1953 1994 can be accurately represented with a fixed parameter discrete choice model thus we model the fed s time varying response with a nonlinear kalman filter the estimated time paths of the reaction function coefficients suggest that the fed has responded countercyclically to movements in the price level except for the middle 1970s when it accommodated inflation the fed has generally responded countercyclically to unemployment and output during recessions however it has not maintained a countercyclical policy during nonrecessionary times until the 1980s a reaction function empirically relates a monetary policy indicator often the federal funds rate or a monetary aggregate to the macroeconomic objectives of monetary policy usually national output inflation and unemployment assuming that the underlying macroeconomy is stable estimated coefficients from a reaction function reveal information about the monetary authority s response to macroeconomic conditions chappell havrilesky and mcgregor 1993 beyond the assumption described above most reaction function studies further assume that the federal reserve s response function is linear in the sense that it contains fixed coefficients see the survey by barth sickles and weist 1982 and more recently chappell havrilesky and mcgregor 1993 that is most studies implicitly assume that the fed responds to a change in inflation for example with the same vigor regardless of whether the level of inflation is unusually high or low and regardless of the timing of the response with respect to the business cycle elections and so on although it is generally recognized that a fixed coefficient estimate of the fed s reaction function overly homogenizes the fed s actual response to macroeconomic conditions solutions to the problem have been ad hoc studies that seek to expose a political business cycle impose structural break points on the fed s reaction function based on pre and postelections periods and then estimate a fixed coefficient reaction function within each subperiod hakes 1988a chappell havrilesky and mcgregor 1993 gamber and hakes 1997 other studies impose structural break points based on political or policy regimes and then estimate a fixed coefficient

falling short of the promise poverty vulnerability in the united states and britain 1993 2003 the welfare state promises to moderate the duration and concentration of poverty the authors ask how well this promise has been fulfilled in the united states and britain from 1993 to 2003 they examine two aspects of poverty vulnerability during this period of welfare reform 1 its persistence and associated risk factors and 2 the efficacy of social transfers after accounting for measurement error sociodemographic characteristics and the impact of redistributive programs the authors find that poverty is often persistent and risk is concentrated especially in the united states moreover the british safety net appears to better protect those at risk

the risk of policy tipping and stranded carbon assets if global warming is to stay below 2 c there are four risks of assets stranding first substantial fossil fuel reserves will be stranded at the end of the fossil era second this is true for exploration capital too third unanticipated changes in present or expected climate policy cause discrete jumps in today s valuation of physical and natural capital fourth if timing and intensity of climate policy are uncertain revaluation of assets occurs as uncertainty about future climate policy is resolved to highlight these four effects we use an analytical model of investment in exploration capital with intertemporal adjustment costs reserves depletion and market capitalization and calibrate it to the global oil and gas industry climate policy implements a carbon budget commensurate with 2 c peak warming and we allow for immediate or delayed carbon taxes and renewable subsidies the social welfare ranking of these instruments is inverse to that of the oil and gas industry which prefers renewable subsidy and delaying taxes for as long as possible we also pay attention to how the legislative risk of tipping into policy action affects the timing of the end of the fossil era the profitability of existing capital and green paradox effects

inflation and stock prices no illusion campbell and vuolteenaho 2004 use var results to advocate inflation illusion as the explanation for the positive association between inflation and dividend yields using a structural approach we find that a fully rational dynamic general equilibrium model can generate a positive correlation between dividend yields and inflation as observed in the data the paper describes a channel by which the technology shock moves both inflation and dividend yields in the same direction resulting in a positive correlation between the two

lumpy investment and corporate tax policy in the presence of both convex and nonconvex capital adjustment costs in a dynamic general equilibrium model corporate tax policy generates both intensive and extensive margin effects via the channel of marginal q i ts impact is determined largely by the strength of the extensive margin effect which in turn depends on the cross sectional distribution of firms depending on the initial distribution of firms the economy displays asymmetric responses to tax changes moreover an anticipated increase in the future investment tax credit reduces investment and adjustment rate initially

firm level investment spikes and aggregate investment over the great recession it is widely accepted that firm level investment is characterized by periods of low investment punctuated by spikes but widely debated whether such lumpiness matters for aggregate investment we provide new empirical evidence that variation in uk aggregate investment is driven by variation in the number of firms undertaking investment spikes this pattern holds for all sectors and across the business cycle we set out and estimate a tractable firm level model of the timing of investment spikes that incorporates the effect of specific macroeconomic factors and aggregates to match observed variation in aggregate investment using simulations we establish that low demand growth was the dominant factor inhibiting uk firms investment spikes immediately following the great recession while heightened uncertainty prolonged low investment and prevented a v shaped economic recovery we use the great recession as a source of exogenous variation with which to study heterogeneity in response to aggregate shocks we find that the minority of firms operating with persistently high debt levels and therefore with balance sheets more exposed to the costs of financial distress were significantly less likely to undertake an investment spike following the recession

slipping into and out of poverty the dynamics of spells this paper examines the dynamics of poverty previous analyses have examined either fluctuations in the male heads earnings or the frequency of poverty periods over a fixed time frame our approach depends on a definition of spells of poverty using this methodology we find that the majority of poor persons at any time are in the midst of a rather long spell of poverty the methodology also allows us to estimate that less than 40 percent of poverty spells begin because of a drop in the heads earnings while 60 percent of the spells end when the heads earnings increase thus researchers must focus on household formation decisions and on the behavior of secondary family members there has been a dramatic resurgence recently of discussion of the underclass the discussion is reminiscent of debates about poverty during the 1960s when the notions of a culture of poverty particularly as popularized by michael harrington s other america 1962 dominated both intellectual and policy thinking the idea of an underclass seems inconsistent however with much of the research on the dynamics of poverty during the 1970s that research using new longitudinal data seemed to show that the bulk of the poor were poor for only a few years the research also showed that the poor were a very heterogeneous group including a small minority of persistently poor the persistence of poverty is of interest both for understanding the phenomenon and for developing policy claims about dependency and separate life styles among the poor rest on assumptions about the long term nature of poverty questions

time varying discrete monetary policy reaction functions a novel dynamic ordered probit model with time varying parameters is proposed to estimate a monetary policy reaction function with narrative based monetary indicators the estimation and inference are carried out using the bayesian simulation based approach empirically these are the following findings first there is strong evidence in support that the central bank in taiwan responds counter cyclically to inflation but weaker if any evidence to economic growth secondly the persistence and consistence in policy making of the monetary authority is confirmed by the significance of the positive autoregressive coefficient although not all the estimates of the tvp dop model provide at least partial support of time varying parameters finally the results indicate that studies of the discrete monetary policy reaction functions without explicitly considering the possible dynamics inherent in the time series data and time variations in model parameters may be inappropriate if not incorrect

lumpy investment and the monetary transmission mechanism abstract the lumpy nature of plant level investment is generally not taken into account in the context of new keynesian monetary theory see e g christiano et al 2005 woodford 2005 our main result shows that if this theory is augmented by a standard model of lumpy investment monetary policy shocks lead to large but very short lived impacts on output and inflation in a way that goes against empirical evidence and the consensus view in the literature

aging and pensions in general equilibrium labor market imperfections matter we re examine the effects of population aging and pension reforms in an olg model with labor market frictions the most important feature brought about by labor market frictions is the connection between the interest rate and the unemployment rate exogenous shocks such as aging leading to lower interest rates also imply lower equilibrium unemployment rates because lower capital costs stimulate labor demand and induce firms to advertise more vacancies these effects may be reinforced by increases in the participation rate of older workers induced by the higher wage rates and the larger probability of finding a job these results imply that neglecting labor market frictions and employment rate dynamics may seriously bias the evaluation of pension reforms when they have an impact on the equilibrium interest rate

the objectives and priorities of monetary policy under different federal reserve chairmen this paper utilizes a monetary policy reaction function that relates policy intentions to forecasts of policy objectives estimates of this reaction function over the post accord period suggest that the burns period was unique while the martin and volcker periods were extremely similar the burns period was structurally distinct from both the martin and volcker periods further model specifications that allow for an independent influence on monetary policy from different presidential administrations also imply that there are significant differences in monetary policy under different fed chairmen copyright 1990 by ohio state university press

the cyclical behavior of the price cost markup countercyclical markups constitute the key transmission mechanism for monetary and other demand shocks in new keynesian models this paper tests the foundation of those models by studying the cyclical properties of the markup of price over marginal cost the first part of the paper studies markups in the aggregate economy and the manufacturing sector we use bils s 1987 insights for converting average cost to marginal cost but do so with richer data we find that all measures of markups are either procyclical or acyclical moreover we show that monetary shocks lead markups to fall with output the second part of the paper merges input output information on shipments to the government with detailed industry data to study the effect of demand changes on industry level markups industry level markups are found to be acyclical in response to demand changes

cyclical productivity in europe and the united states evaluating the evidence on returns to scale and input utilization this paper studies procyclical productivity growth at the industry level in the united states and three european countries france germany and the netherlands industry specific demand side instruments are used to examine the prevalence of non constant returns to scale and unmeasured input utilization for the aggregate us economy unmeasured input utilization seems to explain procyclical productivity however this correction still leaves one in three us industries with procyclical productivity this failure of the model can also be seen in europe and is mostly concentrated in services industries

riskiness endogenous productivity dispersion and business cycles abstract in the data cross sectional productivity dispersion is countercyclical at both the plant level and the firm level see e g bloom 2009 i incorporate a firm s choice of risk level into a model of firm dynamics with real business cycle features to explain this empirical finding both qualitatively and quantitatively in the model in every period each firm chooses the investment amount and the risk level associated with a production project every period all projects available to each firm have the same expected flow return determined by the aggregate and idiosyncratic shocks to the firm s productivity and differ from one another only in their risk the endogenous option of exiting the market and the limited funding for new investment jointly play an important role in motivating firms risk taking behavior the model predicts that in each period relatively small firms are more likely to take risk and hence exhibit a higher exit rate and that the cross sectional productivity dispersion measured as the standard deviation of the realized individual component of productivity is larger in recessions

lumpiness capital adjustment costs and investment dynamics aggregate investment in the us economy displays a hump shaped pattern in response to shocks and the autocorrelation of aggregate investment growth is positive for the first few quarters turning negative for the later quarters this paper shows that this feature of the data is the natural outcome of a two sector consumption investment model designed and calibrated to reproduce plant level evidence on capital accumulation

two sided market r d and payments system evolution abstract it takes many years for more efficient electronic payments to be widely used and the fees that merchants consumers pay for using those services are increasing decreasing over time we address these puzzles by studying payments system evolution with a dynamic model in a two sided market setting we calibrate the model to u s payment card data and conduct welfare and policy analysis our analysis shows that the market power of electronic payment networks plays important roles in explaining the slow adoption and asymmetric price changes and the welfare impact of regulations may vary significantly through the endogenous r d channel

nonconvex factor adjustments in equilibrium business cycle models do nonlinearities matter recent empirical analysis has found nonlinearities to be important in understanding aggregated investment using an equilibrium business cycle model we search for aggregate nonlinearities arising from the introduction of nonconvex capital adjustment costs we find that while such costs lead to nontrivial nonlinearities in aggregate investment demand equilibrium investment is effectively unchanged our finding based on a model in which aggregate fluctuations arise through exogenous changes in total factor productivity is robust to the introduction of shocks to the relative price of investment goods

when is sticky information more information this paper uses sectoral data to study survey based balance indices designed to capture changes in the business cycle in real time the empirical framework recognizes that when answering survey questions regarding their firm s output respondents potentially rely on infrequently updated information the analysis then suggests that their answers reflect notable information lags on the order of 71 2 months on average moreover information stickiness implies that noisy output fluctuations will be attenuated in survey answers and consequently helps explain why balance indices successfully track business cycles conversely in an environment populated by fully informed identical firms as in the standard rbc framework for example balance indices instead become degenerate finally information regarding changes in aggregate output tends to be sectorally concentrated the paper therefore illustrates how this feature of the data may be relevant for the construction of balance indices

lumpy investment lumpy inventories the link between the physical micro environment frictions and heterogeneity and the macroeconomic dynamics in general equilibrium macro models is influenced by the details of how exactly general equilibrium closes such a model we make this general observation concrete in the context of the recent literature on how important nonconvex capital adjustment costs are for aggregate investment dynamics specifically we introduce inventories into a two sector lumpy investment model we find that with inventories nonconvex capital adjustment costs dampen and propagate the reaction of investment to shocks the initial response of fixed capital investment to productivity shocks is 50 higher with frictionless adjustment than with the calibrated capital adjustment frictions once inventories are introduced the reason for this result is that with two means of transferring consumption into the future fixed capital and inventories the tight link between aggregate saving and fixed capital investment is broken in contrast in the case the literature has focussed on with only one type of capital good to save and invest in fixed capital investment dynamics are more tightly linked to consumption dynamics which in turn are determined by the euler equation of a representative household which holds regardless of whether fixed capital investment is costly or not

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

fixed adjustment costs and aggregate fluctuations this paper studies the analytics of a canonical model of xed adjustment costs in the presence of idiosyncratic productivity shocks we provide a novel analytical characterization of the steady state and dynamics of aggregate outcomes implied by the model the dynamics are shown to have an intuitive partial adjustment representation these results are then used to derive a set of approximations to model outcomes in the presence of a small adjustment cost surprisingly these reveal that both aggregate steady state outcomes and aggregate dynamics are approximately neutral with respect to a small xed adjustment cost we show that this neutrality result emerges from a symmetry property in the distributional dynamics of the model and arises even in the absence of general equilibrium adjustment of prices a set of quantitative illustrations con rms these analytical results for parameterizations commonly used in the literature on employment adjustment

menu costs and the neutrality of money a model of endogenous price adjustment under money growth is presented firms follow s s pricing policies and price revisions are imperfectly synchronized in the aggregate price stickiness disappears and money is neutral the connection between firm price adjustment and relative price variability in the presence of monetary growth is also investigated the results contrast with those obtained in models with exogenous fixed timing of price adjustment

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

investment tobin s q and interest rates the interest rate is a key determinant of rm investment we integrate a widelyused term structure model of interest rates cir cox ingersoll and ross 1985 with the q theory of investment hayashi 1982 and abel and eberly 1994 we show that stochastic interest rates have signicant eects on investment and rm value because capital is medium long lived capital adjustment costs have a rst order eect on investment and rm value we use duration to measure the interest rate sensitivity of rm value decompose a rm into assets in place and growth opportunities and value each component by extending the model to allow for endogenous capital liquidation we nd that the liquidation option provides a valuable protection against the increase of interest rates we further generalize the model to incorporate asymmetric adjustment costs a price wedge between purchasing and selling capital xed investment costs and irreversibility we nd that inaction is often optimal for an empirically relevant range of interest rates for rms facing xed costs or price wedges finally marginal q is equal to average q in our stochastic interest rate settings including one with serially correlated productivity shocks

quantifying uk capital adjustment costs this paper estimates uk capital adjustment costs using manufacturing and service industry data for 19702000 there is evidence of significant adjustment costs with a 1 increase in investment reducing value added by 0 05 this implies an elasticity of investment with respect to tobin s q of 2 5 and a convergence time for capital of 12 years the results suggest that adjustment costs may have caused half of the slowdown in uk total factor productivity tfp growth during the second half of the 1990s the impact is larger than that reported for the united states reflecting larger adjustment costs and higher investment growth

a bayesian approach to real options the case of distinguishing between temporary and permanent shocks traditional real options models demonstrate the importance of the option to wait due to uncertainty over future shocks to project cash flows however there is often another important source of uncertainty uncertainty over the permanence of past shocks adding bayesian uncertainty over the permanence of past shocks augments the traditional option to wait with an additional option to learn the implied investment behavior differs significantly from that in standard models for example investment may occur at a time of stable or decreasing cash flows respond sluggishly to cash flow shocks and depend on the timing of project cash flows during the past two decades the real options approach to valuation of irreversible investment opportunities has become part of the mainstream literature in financial economics the central idea is that the opportunity to invest is equivalent to an american call option on the underlying investment project as a consequence the problem of optimal investment timing is analogous to the optimal exercise decision for an american option applications of the real options approach are now numerous 1 one feature that is common to virtually all real options models is that the underlying uncertainty pertains only to future shocks since future cash flows are uncertain there is an important opportunity cost of investing today the value of the asset might go up so that tomorrow will be an even better time to invest this opportunity cost is often referred to in the literature as the option

a unified model of entrepreneurship dynamics we develop an incomplete markets q theoretic model to study entrepreneurship dynamics precautionary motive borrowing constraints and capital illiquidity lead to underinvestment conservative debt use under consumption and less risky portfolio allocation the endogenous liquid wealth illiquid capital ratio w measures time varying financial constraint the option to accumulate wealth before entry is critical for entrepreneurship flexible exit option is important for risk management purposes investment increases and the private marginal value of liquidity decreases as w decreases and exit becomes more likely contrary to predictions of standard financial constraint models we show that the idiosyncratic risk premium is quantitatively significant especially for low w

is lumpy investment relevant for the business cycle the lumpiness of investment activity at the plant level is a well established fact previous research has suggested that such discrete and occasional adjustments have significant aggregate implications in particular it has been argued that changes in plants willingness to invest in response to aggregate shocks can at times generate large movements in total investment demand in this study i reassess these predictions in a general equilibrium environment specifically assuming nonconvex costs of capital adjustment i derive generalized s s adjustment rules yielding lumpy plant level investment within an otherwise standard equilibrium business cycle model in contrast to previous partial equilibrium analyses model results reveal that the aggregate effects of lumpy investment are negligible in general equilibrium households preference for relatively smooth consumption profiles offsets changes in aggregate investment demand implied by the introduction of lumpy plant level investment as a result

measuring factor adjustment costs i estimate adjustment costs for labor and capital from the euler equations for factor demand for both factors i find relatively strong evidence against substantial adjustment costs my estimates use annual data from two digit industries my results support the view that rents arising from adjustment costs are relatively small and are not an important part of the explanation of the large movements of the values of corporations in relation to the reproduction costs of their capital i investigate the potential effects of three types of specification error 1 aggregation over time 2 aggregation over firms with heterogeneous demand shocks and 3 estimation of a convex adjustment cost technology in the presence of nonconvex discrete adjustment costs i find that the likely biases from these specification errors are relatively small

the relation between narrative and money market indicators of monetary policy this paper studies the relation between narrative based indicators of monetary policy and widely used money market indicators of monetary policy three principal findings emerge first changes in monetary policy as measured by the narrative based policy indices are associated with persistent changes in the levels of m2 and the monetary base in contrast changes in the narrative policy indicators lead to transitory changes in short term interest rates nonborrowed reserves and the spread between the six month commercial paper rate and the three month treasury bill rate third these findings are generally robust across different narrative based policy indices

investment dynamics with information costs investment in physical capital at the micro level is infrequent and large or lumpy the most common explanation for this is that firms face non convex physical adjustment costs the model developed in this paper shows that information costs make investment lumpy at the micro level even in the absence of non convex adjustment costs when collecting and processing information is costly the firm optimally chooses to do it sporadically and to be inactive most of the time this behavior results in infrequent and possibly large capital adjustments the model fits plant level investment rate moments well and it also matches some higher order moments of aggregate investment rates keywords investment dynamics information costs inattentiveness lumpy investment jel classification d21 d83 d92 e22

a fallacy of composition the representative agent framework has endowed macroeconomists with powerful microeconomic tools unfortunately it has also blurred the distinction between statements that are valid at the individual level and those that apply to the aggregate in this paper the author argues that probability theory puts strong restrictions on the joint behavior of a large number of units that are less than fully synchronized many fallacies arise from disregarding these restrictions for example asymmetric factor adjustment costs at the firm level need not imply asymmetric responses of aggregate employment flows to positive and negative shocks copyright 1992 by american economic association

input output linkages and sectoral volatility why are some sectors more volatile than others this paper uncovers evidence of an empirical regularity in the us economy upstream sectors that are far removed from final consumers have higher levels of output volatility the relationship between volatility and upstreamness is not driven by sector size sector concentration trade openness or the level of aggregation at which sectors are defined rather the paper shows a stronger link between upstreamness and nominal output volatility than with indexes of real output volatility aggregate exports at the national level also reflect the empirical regularity of higher volatility with upstreamness export volatility is higher in economies with trade portfolios dominated by upstream sectors on average reducing the upstreamness of exports by 1 also reduces aggregate export volatility by about 10 the pattern of higher volatility for upstream sectors is explained with a model of demand shock transmission between sectors

machine replacement and the business cycle lumps and bumps this paper explores investment fluctuations due to discrete changes in a plant s capital stock the resulting aggregate investment dynamics are surprisingly rich reflecting the interaction between a replacement cycle the cross sectional distribution of the age of the capital stock and an aggregate shock using plant level data lumpy investment is procyclical and more likely for older capital further the predicted path of aggregate investment that neglects vintage effects tracks actual aggregate investment reasonably well however ignoring fluctuations in the cross sectional distribution of investment vintages can yield predictable nontrivial errors in forecasting changes in aggregate investment

partisan monetary policies presidential influence through the power of appointment we investigate the channels through which partisan influence from a presidential administration could affect monetary policy making influence could be a result of direct presidential pressure exerted on members of the federal open market committee fomc or it could be a result of partisan considerations in presidential appointments to the board of governors to investigate these two channels of influence we devise and apply a method for estimating parameters of monetary policy reaction functions that can vary across individual members of the fomc our results suggest that the appointments process is the primary mechanism by which partisan differences in monetary policies arise

putty clay technology and stock market volatility abstract firms first order conditions imply that stock returns equal investment returns from the production technology much applied work uses the adjustment cost technology which implies that the realized return is high when the investment capital ratio is high this paper derives for an arbitrary stochastic discount factor the investment return implied by the putty clay technology the combination of capital heterogeneity and irreversibility creates a novel channel for return volatility the investment return is high when the ratio of investment to gross job creation is low empirically the putty clay feature helps account for u s stock market data

the role of non convex costs in firms investment and financial dynamics abstract this paper shows that non convex costs of financial adjustment are quantitatively relevant for explaining firm dynamics first empirically financial activity is lumpy more than investment activity second non convex costs are necessary in the context of a dynamic investment and financing model to rationalize this lumpiness two versions of the model with and without non convex costs are compared only the non convex costs version replicates the dynamics in the data generating financial lumpiness higher than investment lumpiness other predictions of the model with respect to investment and finance are discussed

dynamic adjustment in us agriculture under climate change we construct a stochastic dynamic dual model to investigate the structural adjustment of two aggregate output and three aggregate input categories in us agriculture under stochastic climatic change more than a century of national annual data 1910 2011 is used in the empirical analysis no constraints on asset fixity are imposed results indicate that with rational expectations both output categories as well as all input categories exhibit quasi fixity in response to market change and stochastic climate change crops adjust more than twice as fast as livestock 49 versus 20 of the way toward their long run equilibrium in one year fertilizer adjusts most rapidly toward equilibrium levels 88 in one year and capital adjusts most slowly 5 in one year labor oscillates rather than converging smoothly toward equilibrium its distance from equilibrium is the same as if it adjusted 59 of the way toward its optimal level in one year failing to anticipate climate change dramatically slows the estimated rate of adjustment for two netputs and modestly speeds the rate for two others thus likely increasing overall adjustment costs failing to account for uncertainty in anticipated climate change has little impact on adjustment rates

estimating the euler equation for aggregate investment with endogenous capital depreciation this article looks at the empirical consequences of introducing endogenous capital depreciation in the standard neoclassical model with quadratic adjustment costs to this end we formulate an empirical specification that accommodates capital maintenance and utilization in the euler equations for aggregate investment the empirical estimates with data from the canadian survey on capital and repair expenditures show that in contrast to the existing literature the performance of the euler equations is improved when we account for the impact of variable capital depreciation

lumpy investment sticky prices and the monetary transmission mechanism abstract smoothness in aggregate capital accumulation is a necessary condition for new keynesian nk models to imply a quantitatively relevant monetary transmission mechanism see e g woodford 2005 firm specific capital and the new keynesian phillips curve international journal of central banking 2 1 46 can that aggregate smoothness be entertained in the context of an nk model featuring lumpy plant level investment our answer is yes imperfect competition in goods markets and or sticky prices are identified as economic mechanisms which render lumpy investment relevant in general equilibrium

evidence on the role of cash flow for investment abstract recent work in macroeconomics argues that imperfections in capital markets may lead to business cycle fluctuations by propagating relatively modest shocks evidence for such a mechanism also known as the financial accelerator consists largely of firm level studies showing that cash flow is an important predictor of investment but this evidence is often viewed with skepticism because cash flow is also a good indicator of investment opportunities in this paper we develop a framework for estimating the extent to which the predictive power of cash flow can be attributed to its role as a fundamental versus its role in alleviating credit frictions for firms with access to commercial paper and bond markets we find that the perfect capital markets model of investment can fully account for the role of cash flow for firms with only limited access to capital markets as indicated by lack of participation in public debt markets however investment appears to be excessively sensitive to fluctuations in cash flow these results thus clarify the role of cash flow in investment equations and provide support for the existence of a financial accelerator

monetary policy and presidential elections a nonpartisan political cycle this paper develops a federal reserve reaction function which relates policy intentions to forecasts of policy objectives pre and postpresidential election estimates of this reaction function for the post accord period of 1953 1984 suggest two conclusions

credit reallocation deleveraging and financial crises this paper studies how the process of reallocation of credit across firms behaves before and after financial crises applying the methodology typically used for measuring job reallocation we track credit reallocation across korean firms for over three decades 1980 2012 the credit boom preceding the 1997 crisis featured a slowdown of credit reallocation after the crisis and the associated reforms the creditless recovery deleveraging masked a dramatic intensification and increased procyclicality of credit reallocation the findings suggest that the intensification of reallocation was efficiency enhancing

schumpeter meeting keynes a policy friendly model of endogenous growth and business cycles this paper studies an agent based model that bridges keynesian theories of demandgeneration and schumpeterian theories of technology fueled economic growth we employ the model to investigate the properties of macroeconomic dynamics and the impact of public polices on supply demand and the fundamentals of the economy we find profound complementarities between factors influencing aggregate demand and drivers of technological change that affect both short run fluctuations and longterm growth patterns from a normative point of view simulations show a corresponding complementarity between keynesian and schumpeterian policies in sustaining long run growth paths characterized by milder fluctuations and relatively lower unemployment levels the matching or mismatching between innovative exploration of new technologies and the conditions of demand generation appear to suggest the presence of two distinct regimes of growth or absence thereof characterized by different short run fluctuations and unemployment levels

dynamic coordination and the optimal stimulus policies this article studies stimulus policies in a simple macroeconomic model featuring a dynamic coordination problem that arises from demand externalities and fixed costs of investment in times of low economic activity firms face low demand and hence have lower incentives for investing which reinforces their low demand expectations in a benchmark case with no shocks the economy might get trapped in a low output regime and a social planner would be particularly keen to incentivise investment at times of low economic activity however this result vanishes once shocks are considered

adjustment costs and threshold effects in factor demand relationships abstractit has been recently argued that producers may not respond to every input price change in the way that a linear factor demand model would predict this lumpy response is due to adjustment costs that are inherent in the act of adjusting the mix of inputs applied in the underlying production technologies this study aims to provide a solid conceptual framework for these nonlinearities in factor demand relationships industry specific implications of convex and non convex adjustment costs for the linearity of the factor demand relationships as well as price and substitution elasticities are explored a two regime threshold system of factor demand equations is estimated for several manufacturing industries in the united states empirical results suggest significant threshold effects in the factor demand relationships in most nondurable goods sectors the size and the nature of thresholds depend upon industry characteristics including input composition and non convexity of underlying adjustment costs

rational inefficiency adjustment costs and sequential technologies abstract in this paper we propose a novel approach to estimate the rational inefficiency of decision making units in the presence of adjustment costs using sequential definitions of the production technology we show how cost inefficiency can be decomposed into rational and residual inefficiency as well as inefficiency caused by technical change furthermore we estimate lower bounds for the unobserved adjustment costs based on unexploited cost reductions due to rational inefficiency these adjustment costs are used to evaluate the feasibility of exploiting cost reductions caused by residual inefficiency we demonstrate the empirical applicability of our model by estimating and decomposing the cost inefficiency of u s coal fired power plants using panel data which cover the period between 1994 and 2009

state dependent pricing and the general equilibrium dynamics of money and output economists have long suggested that nominal product prices are changed infrequently because of fixed costs in such a setting optimal price adjustment should depend on the state of the economy yet while widely discussed statedependent pricing has proved difficult to incorporate into macroeconomic models this paper develops a new tractable theoretical state dependent pricing framework we use it to study how optimal pricing depends on the persistence of monetary shocks the elasticities of labor supply and goods demand and the interest sensitivity of money demand

determinants of relative poverty in advanced capitalist democracies using relative poverty measures based on micro level data from the luxembourg income study in conjunction with pooled time series data for 14 advanced capitalist democracies between 1970 and 1997 the authors analyze separately the rate of pretax transfer poverty and the reduction in poverty achieved by systems of taxes and transfers socioeconomic factors including de industrialization and unemployment largely explain pre tax transfer poverty rates of the working age population in these advanced capitalist democracies the extent of redistribution measured as poverty reduction via taxes and transfers is explained directly by welfare state generosity and constitutional structure number of veto points and the strength of the political left both in unions and in government

new and old models of business investment a comparison of forecasting performance previous empirical evaluations of investment models have focused on the relative in sample fit of various nonstructural models the authors evaluation extends this work along two dimensions first they augment the usual set of models with two euler equations derived explicitly from dynamic optimization under rational expectations one euler equation is typical of those found in the investment literature while the other embeds time to build lags that yield a richer dynamic structure second the authors focus on out of sample forecast performance as the primary criterion of model evaluation their results indicate that the traditional models dominate both euler equations in forecasting investment copyright 1995 by ohio state university press

idiosyncratic shocks and the role of nonconvexities in plant and aggregate investment dynamics we examine a model of lumpy investment wherein establishments face persistent shocks to common and plant specific productivity and nonconvex adjustment costs lead them to pursue generalized s s investment rules we allow persistent heterogeneity in both capital and total factor productivity alongside low level investments exempt from adjustment costs to develop the first model consistent with available evidence on establishment level investment rates reassessing the implications of lumpy investment for aggregate dynamics in this setting we find that they remain substantial when factor supply considerations are ignored but are quantitatively irrelevant in general equilibrium the substantial implications of general equilibrium extend beyond the dynamics of aggregate series while the presence of idiosyncratic shocks makes the time averaged distribution of plant level investment rates largely invariant to market clearing movements in real wages and interest rates we show that the dynamics of plants investments differ sharply in their presence thus model based estimations of capital adjustment costs involving panel data may be quite sensitive to the assumption about equilibrium our analysis also offers new insights about how nonconvex adjustment costs influence investment at the plant when establishments face large and weakly persistent idiosyncratic productivity shocks consistent with existing estimates we find that nonconvex costs do not cause lumpy investments but act to eliminate them

child poverty in britain and the united states child poverty rose sharply in britain and the us in the period preceding the blair and clinton governments so that over a third of children were in poverty in both countries demographic change falls in work and increasing wage inequality all contributed to this rise in britain with benefit changes having an offsetting effect in the us demographic and wages changes were the drivers both administrations acted with a range of welfare reforms aimed at increasing work incentives and in britain benefits for those not working were also raised child poverty fell under the blair and clinton governments with work and benefit changes explaining most of the fall in britain and work and demographic change the us fall

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

the federal reserve s response to aggregate demand and aggregate supply shocks evidence of a partisan political cycle the orthodox approach to modeling the fed s response to economic conditions is to employ a monetary policy reaction function most reaction functions are estimated by regressing a policy indicator possibly the federal funds rate or a monetary aggregate on variables that describe the state of the economy such as unemployment inflation and growth in output under certain conditions which we discuss below estimated coefficients from a reaction function provide information about the fed s monetary policy priorities moreover extending the model to include election and partisan dummy variables may provide information about the fed s response to political pressures there are two problems with interpreting the coefficients in a standard reaction function as the weights that the fed attaches to its policy objectives first the monetary policy decision may not be represented accurately by an aggregate reaction function one that models the fed as a whole because there are twelve voting members on the fomc chappell havrilesky and mcgregor 10 have recently addressed this issue by employing a disaggregated set of reaction functions the second problem with interpreting reaction function coefficients as the weights the fed places on its policy objectives is that this interpretation implicitly assumes structural stability of the underlying macroeconomy abrams froyen and waud 1 31 acknowledge this shortcoming when they state coefficients from estimated reaction functions do not provide direct information on policymaker utility functions rather than being the solution to an unconstrained optimization dependent only on policymaker preferences reaction functions are the output of a constrained maximization where the constraints are the reduced form equations that characterize
