can stabilisation policy reduce long run growth this paper presents an analysis of the long run implications of short term stabilisation policy the analysis is based on a simple stochastic model of an imperfectly competitive economy with nominal rigidities and an endogenous technology by virtue of the latter temporary shocks have permanent effects such that the cyclical and secular properties of output are related in particular smoother cyclical fluctuations may be associated with flatter secular trends implying a trade off between short term stabilisation and long term growth

long term growth and short term economic instability when learning by doing is at the origin of growth the long run growth rate should be negatively related to the amplitude of the business cycle if human capital accumulation is increasing and concave in the cyclical component of production empirical evidence strongly supports this nding for industrialized countries and european regions using the standard control variables we nd that countries and regions that have a higher standard deviation of growth and of unemployment have lower growth rates the result does not come from an e ect of instability on investment the negative relation however does not hold for non industrialized countries for which learning by doing may not to be the main engine of growth 2000 elsevier science b v all rights reserved jel classixcation o40 e32

unemployment persistence is there evidence for stigma effects we present evidence for a highly significant interaction between state dependence in individual unemployment risk and the business cycle the disadvantage from having been unemployed in the previous period is smaller in times of relatively high unemployment and larger in times of low unemployment this is consistent with the existence of stigma effects in the sense that unemployed individuals face difficulties finding a new job because employers interpret unemployment as a negative signal and do so especially when it is easier to find jobs i e when unemployment is low

business cycles and long run growth in this survey we discuss the effect of macroeconomic fluctuations on long run growth from both a theoretical and empirical perspective we emphasize the opportunity cost approach which states that firms will intertemporally substitute productivity enhancing activities for regular production activity during recessions we provide aggregate evidence in favor of the opportunity cost approach copyright 1997 by oxford university press

unemployment dynamics and duration dependence in france the netherlands and the united kingdom this paper analyzes unemployment dynamics in the french dutch and u k labor market it presents a method to distinguish between the effects of duration dependence and unobserved heterogeneity on the exit rate out of unemployment it turns out that for british male unemployed there is strong genuine negative duration dependence for french unemployed there is no strong duration dependence during the first year of unemployment while for dutch unemployed there is nonmonotonic duration dependence for all groups of french and dutch individuals significant unobserved heterogeneity is found for u k male unemployed heterogeneity seems to be empirically unimportant copyright 1994 by royal economic society

common trends and common cycles in international labor productivity abstract the objective of this paper is to present a trend cycle decomposition of the industrial labor productivity series in six major industrialized countries to study the relationship between trend and cycle innovations and to highlight the role of monetary policy as a possible source of transitory and permanent variations in labor productivity

the british low wage sector and the employment prospects of the unemployed abstractare low wages a way for the unemployed to switch to higher paying jobs using data from the british household panel survey the labour market dynamics of unemployed low paid and higher paid employed men are analysed moreover the respective un employment duration and occupational skill level are accounted for results show that in general low wages significantly reduce the risk of future unemployment and increase the chances of ascending the salary ladder especially in the case of long term unemployment 360 days furthermore the occupational skill level has a substantial influence on the upward mobility of low paid jobs individuals working in the initial period in a low paid and higher skilled occupation have on average an 11 percentage points higher probability of entering higher pay compared to when working in a low paid and low skilled occupation

innovative activity over the business cycle this paper examines cyclical patterns of innovative activity in the united kingdom over the period 1948 83 innovative activity turns out to have many of the properties of a random walk but does show a tendency to cluster during booms there is clear evidence of a long term secular relation between the level of innovative activity and the level of economic activity although this may have changed in the 1980s finally the data provide no reason for thinking that these clusters of innovation cause cyclic variations in economic activity but variations in economic activity do granger cause changes in innovative activity copyright 1995 by royal economic society

business cycles and research investment this paper examines the impact of uncertainty and the business cycle on us high tech manufacturing firms research investment although the reliance on internal financing suggests firms will consider uncertainty and the business cycle when determining their research budget little is known about how the business cycle and uncertainty influence research investment using firm level data on sales cash flow and industry level indicators of the business cycle this paper finds that the firm s response to the business depends on the firm s industry and the industry s current location in the business cycle the data also shows that the business cycle also depresses the firm s reaction to changes in sales and cash flow uncertainty clearly reduces research efforts although non linearly

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

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

job search stigma effect and escape rate from unemployment this article formulates job search models incorporating certain types of the stigma effect of unemployment it is assumed that the probability of getting a job offer given the unemployment individual contacts the firm is influenced by the duration of unemployment and is justified in a signaling context the optimal search is analyzed for one sector as well as across several independent labor market segments it is shown that there are reasonably general conditions on the search environments for which both the individual reservation wage and escape rate are negative duration dependent a fact observed in empirical studies

the great moderation and the relationship between output growth and its volatility this study examines the effect of the great moderation on the relationship between u s output growth and its volatility over the period 1947 to 2006 first we consider the possible effects of structural change in the volatility process in so doing we employ garch m and arch m specifications of the process describing output growth rate and its volatility with and without a one time structural break in volatility second our data analyses and empirical results suggest no significant relationship between the output growth rate and its volatility favoring the traditional wisdom of dichotomy in macroeconomics moreover the evidence shows that the time varying variance falls sharply or even disappears once we incorporate a one time structural break in the unconditional variance of output starting 1982 or 1984 that is the integrated garch effect proves spurious finally a joint test of a trend change and a one time shift in the volatility process finds that the one time shift dominates

how changes in labor demand affect unemployed workers this study analyzes the manner in which certain favorable shifts in labor demand affect job search although all shifts increase reservation wages they do not necessarily decrease expected unemployment spell durations and increase expected post unemployment wages so that upward sloping short run phillips curves may occur a result due to chamberlain is used to demonstrate that if the wage offer distribution is restricted to be logconcave two of the shifts guarantee downward sloping phillips curves for one of these two shifts previous research by flinn and heckman used logconcavity in a different manner to achieve properly shaped phillips curves

scar effects of unemployment an assessment of institutional complementarities this article uses panel data from the survey of income and program participation sipp and the european community household panel echp for a comparative analysis of workers post unemployment earnings trajectories in the united states and 12 western european countries across the study sample of industrialized countries results of difference in difference propensity score matching show post unemployment earnings losses to be largely permanent and particularly significant for high wage and older workers as well as for women the analyses also show that negative effects of unemployment on workers subsequent earnings are mitigated through either generous unemployment benefit systems or strict labor market regulation these effects stem partly from favorable behavioral responses that prevent downward occupational and industrial mobility and partly from changes in the overall structure of labor markets favoring the transferability of worker skills between jobs these positive effects materialize despite t

a socio economic model of stigma and related social problems abstract recent years have seen a rapid expansion of economic literature on stigma a notion that had been widely studied in sociology in relation to social deviance yet the economic literature overlooks the original sociological intuition that certain consequences of stigmatization could be socially inefficient this paper formalizes this intuition by developing a model of community behavior which mimics a classic sociological setting concerning the rehabilitation of a former criminal offender the conditions under which a socially inefficient equilibrium arises are derived some of those conditions are shown to be consistent with the findings from micro labor studies on crime

an empirical examination of the procyclicality of r d investment and innovation abstract the schumpeterian opportunity cost hypothesis predicts that firms concentrate innovative activities in recessions however empirical evidence suggests that innovative activities are procyclical theory proposes that firms shift r d investments and innovation from recessions to booms to maximize returns by capturing high demand periods before imitators compete away rents this paper provides the first empirical test of these predictions results indicate that r d spending is more procyclical in industries with faster obsolescence where matching invention to demand is more valuable and innovation is more procyclical in industries with weaker ip protection where imitation poses a greater threat

spectral and persistence properties of cyclical growth abstract this article investigates the cyclical properties of an endogenous growth model an explicit solution is derived which permits the full characterization of the cyclical as well as the long run properties of the model using spectral autocorrelation and impulse response functions we show that introducing endogenous growth overcomes some of the main shortcomings of rbc models in particular the model can generate positive autocorrelation of output growth when endogenous growth dominates the dynamics moreover the model exhibits the hump shaped pattern of impulse response functions of the trend reverting component of output

sources of productivity growth an empirical analysis with german sectoral data many theoretical analyses of the sources of economic growth focus on knowledge spillovers and scale economies to explain growth endogenously the contribution of this paper is to shed some light on these arguments by an empirical investigation based on a production function framework sectoral production functions are estimated with annual german data of 51 sectors from 1960 90 the estimates reveal that both a pure solow growth model and a solow model augmented with human capital cannot account for the observed productivity increases the model should be extended by allowing for inter industry spillovers and scale economies at the aggregate level as well as for scale economies associated with human capital at the sectoral level the business cycle affects observed productivity changes in the short run and in the long run

parallel search and information gathering many microeconomic problems fall into the following category a decision maker has a number n of opportunities or projects each project yields an unknown reward at an uncertain time and is characterized by an independent joint probability distribution once a project is selected its reward is revealed after a random time lag when it is collected the projects are selected sequentially in any order desired furthermore at any time a number m 1 m n of projects may be explored simultaneously that is in parallel the decision problem is to determine the sequential strategy for choosing the projects to maximize an objective which is a function of the rewards collected most of the problems in search theory dynamic allocation problems and many information gathering problems fall into this class a firm s problem of choosing technologies to develop products job search decision of workers price search of consumers development of resource pools exploration problems of mines and wells investment decisions and marketing strategies are but a few examples where the problem stated above is naturally applicable indeed the problem is basic to many imperfect information contexts and its analysis reveals useful insights into the nature of information acquisition and structures of markets the motivation for the study of parallel search and information gathering models is obvious in problems where information acquisition is costly and time consuming the returns to parallel effort are higher than when undertaking a single project at a time for example in research and development contexts if large improvements in information are possible at low cost in early stages of development then it becomes efficient to run several projects in parallel in scheduling and dynamic allocation applications where all projects must be undertaken parallel operation substantially reduces the overall completion time the instance of the problem when only one project can be chosen at a time m 1 has been studied extensively in recent economic literature in contrast there has been no significant attempt to study parallel selection of projects unfortunately the elegant results that may be derived for singleproject selection do not readily generalize to the parallel project case furthermore this problem in principle may be formulated in a dynamic programming framework and solved through standard techniques such as backward induction or fixed point methods however in most actual cases this approach besides shedding little economic insight would be a combinatorially complex task of formidable proportions unless n and m are small hence there is a need to study the effectiveness of meaningful operational rules the purpose of this paper is to point out that simple ordering rules are obtained for the optimal parallel selection of projects under reasonably general and meaningful conditions these conditions may be stated in terms of risks and stochastic orderings of the distributions associated with the projects the problem of single project selection m 1 falls into the general class of bandit processes see the works of j c gittens 1979 and others the solution for which is usually characterized by a reservation rule each project is assigned a reservation number or an index analogous to internal rate of return depending only on the features of that project and independent of all other projects at each decision instant the project with the highest reservation number is selected these reservation numbers as department of economics and center for urban affairs and policy research northwestern university evanston il 60201 research supported by nsf grant ses 8708325

productivity growth and the structure of the business cycle abstract over the recent years opportunity cost oc models of growth have argued that recessions are times when firms engage in productivity improving activities because of intertemporal substitu tion this paper tests whether this approach is correct the technique used to disentangle the trend from the cycle is semi structural vector autoregression the results are mildly supportive of the oc theory there tends to be a negative impact of demand shocks on productivity both in the short run and in the long run and the short run impact is stronger in those countries where fluctuations are more transitory however there is no significant response of r d to demand shocks

are output fluctuations transitory according to the conventional view of the business cycle fluctuations in output represent temporary deviations from trend the purpose of this paper is to question this conventional view if fluctuations in output are dominated by temporary deviations from the natural rate of output then an unexpected change in output today should not substantially change one s forecast of output in say five or ten years our examination of quarterly postwar united states data leads us to be skeptical about this implication the data suggest that an unexpected change in real gnp of 1 percent should change one s forecast by over 1 percent over a long horizon

declining reservation wages and learning empirical studies of job search strongly suggest that the reservation wages of unemployed job seeking individuals decline with the length of their respective unemployment spells previous explanations of this behaviour based on age effects liquidity constraints and limited unemployment benefits are not adequate we provide a new answer to this question based on the reasonable assumption that workers do not have precise knowledge of the distribution of the prevailing wages an individual model of job search and learning is formulated it is shown that the declining trend of reservation wages naturally arises due to the selection process when search costs are not too small the example of a normal wage offer distribution is analysed and the implications are discussed

on the effects of ranking by unemployment duration abstract we propose a theory based on the firm s hiring behavior that rationalizes the observed significant decline of callback rates for an interview and exit rates from unemployment and the mild decline of reemployment wages over unemployment duration we build a directed search model with symmetric incomplete information on worker types and non sequential search by firms sorting due to firms testing of applicants in the past makes expected productivity fall with duration which induces firms to rank applicants by duration in equilibrium callback and exit rates both fall with unemployment duration in our numerical exercise using u s data we show that our model can replicate quite well the observed falling patterns with the firm s ranking decision accounting for a sizable part

demand shocks and firm financed r d expenditures business cycles might affect firms ability and incentive to perform r d firms finance most r d activities out of cash flow so when cash flow decreases the funds available for r d also decreases this limits the ability of firms to perform r d potentially leading to reduced r d expenditures during recessions however business cycles also influence the incentive to perform r d the opportunity cost of funds devoted to r d falls during recessions since the return on production will likely be lower than during an expansion during recessions this provides firms with an incentive to redistribute an existing pool of funds away from production and towards r d projects this paper tests whether the business cycle influences the incentive and ability of firms to engage in r d activities in particular examining whether the response is symmetric across the business cycle

procyclical labour productivity a closer look at a stylized fact at 4 digit united states manufacturing industry level we find evidence suggesting that the stylized fact of procyclical labour productivity should be treated with great caution we use the nber manufacturing productivity database to investigate the relationship between hourly labour productivity and real output for 450 industries for the years 1958 91 labour productivity is significantly procyclical in 63 of industries and acyclical in 36 in the latter respect a high proportion of investment goods industries display acyclical productivity cross section regressions are carried out that seek to explain the interindustry distribution of cyclicality the analysis attributes a significant role to variations in materials costs as a proxy for fluctuations in factor utilization

costly search with adverse selection solicitation curse versus acceleration blessing we analyze a dynamic trading model of adverse selection where a seller can increase the frequency of strategic price quotes a low quality seller benefits more from trade and therefore searches more intensively than a high quality seller this makes a seller s contact carry negative information but a seller s availability become a stronger indicator of high quality in the stationary environment the two effects exactly offset each other and reducing search costs is weakly beneficial to the seller in the nonstationary environment the relative strengths of the two effects vary over time and reducing search costs can be detrimental to the seller

statistical discrimination and duration dependence in the job finding rate this article models a frictional labour market where employers endogenously discriminate against the long term unemployed the estimated model replicates recent experimental evidence which documents that interview invitations for observationally equivalent workers fall sharply as unemployment duration progresses we use the model to quantitatively assess the consequences of such employer behaviour for job finding rates and long term unemployment and find only modest effects given the large decline in callbacks interviews lost to duration impact individual job finding rates solely if they would have led to jobs we show that such instances are rare when firms discriminate in anticipation of an ultimately unsuccessful application discrimination in callbacks is thus largely a response to dynamic selection with limited consequences for structural duration dependence and long term unemployment

heterogeneity and unemployment dynamics many previous articles have studied the contribution of inflows and outflows to the cyclical variation in unemployment but ignored the critical role of unobserved heterogeneity across workers thi

duration dependence and labor market conditions evidence from a field experiment this article studies the role of employer behavior in generating negative duration dependence the adverse effect of a longer unemployment spell by sending fictitious resumes to real job postings in 100 u s cities our results indicate that the likelihood of receiving a callback for an interview significantly decreases with the length of a worker s unemployment spell with the majority of this decline occurring during the first eight months we explore how this effect varies with local labor market conditions and find that duration de pendence is stronger when the local labor market is tighter this result is consistent with the prediction of a broad class of screening models in which employers use the unemployment spell length as a signal of unobserved productivity and recognize that this signal is less informative in weak labor markets jel code j64

the influence of industry downturns on the propensity of product versus process innovation this article sheds light on how industry fluctuations affect firms propensity to innovate we test two seemingly conflicting arguments that suggest how firms are more or less inclined to engage in innovation activities during industry fluctuations by studying a panel of 622 italian manufacturing firms during the period 1995 2003 we show how differentiating between product and process innovation may help reconcile the theory of opportunity cost of innovation with the cash flow effect argument we find that industry downturns are related to product and process innovation in different ways firms tend to invest in product innovation rather than process innovation in downturns the findings have implications for both theory showing when the opportunity cost of innovation dominates and research design showing the importance of both the input and output measures in innovation studies and how they might influence the results

politics and the pursuit of fame humans strive after fame especially in politics we construct a model in which the executive is motivated by fame as well as the desire to hold office the fame of an executive is based on his or her achievements relative to all prior executives periods of great uncertainty for a nation make politicians more likely to pursue fame rather than reelection we show that fame incentives weaken as a country ages if politicians are wiser than the median voter then the pursuit of fame by politicians improves welfare and the diminution of fame incentives over time causes national decline

the effects of expected and unexpected volatility on long run growth evidence from 18 developed economies 1 introductionalthough there is disagreement about the magnitude many economists agree that business cycles have negative consequences for welfare in the short run by causing output to deviate from potential as a result most policymakers regard reducing volatility as a desirable goal however there is disagreement about the long run consequences of business cycles some models suggest that business cycle volatility should reduce long run growth in these models increased volatility increases risk reduces investment and slows the growth rate of output in addition volatility may reduce the diffusion rate of new technology which might reduce the long run growth rate hence business cycles have negative short run consequences by causing output to deviate from the trend and negative long run consequences by slowing the long run growth rate if these models are accurate then the welfare consequences of business cycles are more severe than previously thought an alternative view of the growth volatility relationship suggests that there may be a long run benefit to business cycles in these models increased volatility stimulates inventive activity which increases the long run growth rate reduced volatility will be beneficial in the short run but if reduced volatility decreases the long run growth rate then there are costs to stabilization as a result policymakers would face a trade off between business cycle volatility and long run growth in addition it is possible that the long run costs of stabilization policy might exceed the short run benefits this article sheds new light on the growth volatility relationship first this article focuses on two types of volatility expected volatility and unexpected volatility this allows a more thorough test of the two general hypotheses linking growth to volatility second this article empirically examines the relationship between growth and volatility for 18 industrialized nations over a 110 year period therefore the analysis avoids the problem of short time span of data this article proceeds as follows section 2 clarifies the relationship between the competing hypotheses as well as between expected and unexpected volatility section 3 analyzes the growth volatility relationship without making the distinction between expected and unexpected volatility section 4 uses generalized method of moments gmm and ordinary least squares ols along with panel data to estimate the effects of expected and unexpected volatility on growth section 5 concludes with suggestions for further research 2 the growth volatility relationshipthe view that business cycle volatility reduces the long run growth rate focuses on risk bernanke 1983 ramey and ramey 1991 and pindyck 1991 argue that volatility creates risk about future demand and that firms are unlikely to invest in new plants and equipment if they are unsure about the demand for their product the greater the volatility in output the more uncertain future demand becomes the greater the risk and the less likely firms are to invest this negative relationship between volatility and investment might lead to a negative relationship between growth and volatility increased volatility decreases investment which then slows the growth rates of the capital stock and output the effect would be especially pronounced if new technology is embodied in new capital goods ramey and ramey 1995 and macri and sinha 2000 have found results consistent with this view of the growth volatility relationship using aggregate data this view emphasizes the risks associated with unexpected changes in output when firms cannot accurately forecast the demand for their goods they reduce capital expenditures which reduces growth the view that business cycles might increase long run growth focuses on the opportunity cost of productivity enhancing activities peas bean 1990 and saint paul 1993 view firms as solving an intertemporal profit maximizing problem in which producing goods provides profits today but engaging in peas produces profits only in the distant future

taxation risk taking and growth a continuous time stochastic general equilibrium analysis with labor leisure choice abstract this paper investigates the equilibrium relationship between taxation portfolio choice risk taking and capital accumulation specifically it examines how taxes affect risk taking and capital accumulation we extend the existing literature by relaxing two crucial assumptions in modelling risk taking behavior i that the investment opportunity set is fixed and ii that there is no distinction between attitudes towards risk and behavior towards intertemporal substitution we extend the investment opportunity set of individuals through optimally determined human capital and distinguish intertemporal substitution from attitudes towards risk via a recursive utility function in the presence of these extensions the paper successfully derives a closed form solution to the stochastic growth model with stochastic wage income

unemployment and growth some empirical evidence from structural time series models this study investigates the empirical relationship between unemployment and growth in a number of oecd economies a structural time series model is used for labour productivity growth to demonstrate that in most economies there seems to be a negative correlation between unemployment and labour productivity growth the results provide little support for the theory that recessions may stimulate productivity growth the use of a structural time series approach allows an attempt to model the underlying dynamics of productivity growth jointly with the effect of unemployment

r d expenditure in g7 countries and the implications for endogenous fluctuations and growth abstract the literature on endogenous growth cycles predicts countercyclical r d expenditure aggregate r d expenditure in g7 countries from 1973 to 2000 tends to be procyclical implications for future theoretical research are discussed

increasing returns labour utilization and externalities procyclical productivity in the united states and japan this paper investigates procyclical productivity and attempts to discriminate among several competing explanations the study focuses on the united states and japan since the different industrial relations in these two economies serve to cast a sharper light on the procyclical productivity debate labour hoarding evaluated through the introduction of a labour utilization proxy proves to be an important influence the interpretation of the role of external economies remains an open issue

the anatomy of unemployment dynamics abstract this paper examines the relation between individual unemployment durations and incidence inflow size on the one hand and the time varying macroeconomic conditions in the economy on the other we develop a model for the analysis of aggregate unemployment incidence and duration data and estimate this model on quarterly french data over the period 1982 1994 stratified by sex we find upward trends in both incidence and durations the former is relatively important for females the latter for males male incidence and durations are countercyclical with only a minor role for cohort effects on durations in contrast female cohorts entering at the top of the cycle have relatively short unemployment spells and the female incidence is if anything procyclical there is strong seasonal variation in particular in the incidence finally we find relatively small non monotonic individual duration dependence in the first six quarters of unemployment unobserved heterogeneity explains the observed negative duration dependence at these durations we provide some evidence that negative individual duration dependence and not heterogeneity is important at higher durations

endogenous growth and the procyclical behaviour of productivity abstract in this paper a model with endogenous growth is used to explain the procyclical behaviour of productivity periods when the marginal return to goods production is high are associated with low levels of human capital formation and other investment like activities in particular the model successfully explains the surges in productivity exhibited in the uk during wartime and the apparently permanent effect of the level of defence spending on the growth of total factor productivity

endogenous growth cycles current explanations why a growing economy necessarily goes through periods of high and low growth predict countercyclical r d investment as this is very controversial from an empirical perspective a stochastic poisson model of endogenous growth cycles is presented where the determinants of the cyclical behaviour of r d investment are analytically studied providing an explicit expression for the expected length of a cycle shows that high frequency fluctuations can indeed be understood by this approach it is also shown how small technological improvements translate into large aggregate fluctuations

job creation and job destruction by small firms an empirical investigation for the dutch manufacturing sector this paper studies the differences in behaviour of small and large firms concerning job creation and job destruction in the dutch manufacturing sector over the period 1978 1991 we find that both job creation and job destruction rates are higher in small firms than in large ones in addition we found that the persistence of jobs created in slumps are much higher for small firms than for large firms persistence rates of job destruction are however less connected to the state of the business cycle and increase with firm size more importantly small firms seem to reallocate their jobs in a continuous way as job turnover moves independent of the business cycle large firms on the other hand reallocate counter cyclically an obvious explanation for this phenomenon is that small firms are better equipped to adjust to shifts in economic circumstances large firms adjust only slowly and for them reallocating jobs in a recession is more advantageous than in a boom

the duration of unemployment as a signal abstract a model is studied in which the unemployment duration of job applicants affects firms hiring decisions the equilibrium wage offered to applicants is decreasing in their unemployment duration a fraction of the workers whose unemployment spell exceeds a critical length withdraws from the labor market

the effects of unemployment and underemployment on employment opportunities results from a correspondence audit of the labor market for college graduates the authors use data from a resume audit to estimate the impact of unemployment and underemployment on the employment prospects of recent college graduates they find no statistical evidence linking unemployment spells of different durations to employment opportunities by contrast college graduates who are underemployed have callback rates that are 30 lower than those of applicants who are adequately employed the null effects associated with unemployment and the adverse effects associated with underemployment are robust across cities with relatively tight and loose labor market conditions internship experience obtained while completing one s degree substantially reduces the negative effects of underemployment the data support the proposition that employers view underemployment as a strong signal of lower expected productivity

on the cyclicality of r d this paper explores the link between short run cycles and long run growth by examining the cyclicality of rd but aggregate data repeatedly show that rd but interestingly estimates using demand shift instruments suggest that it responds asymmetrically to demand shocks we propose that liquidity constraints and technology improvement cause the observed pro cyclicality of r d

the impact of r d subsidies during the crisis this study investigates the impact of r d subsidies on r d investment during the past financial crisis we conduct a treatment effects analysis and show that r d subsidies increased r d spending among subsidized small and medium sized firms in germany during the crisis years in the first crisis year the additionality effect induced by public support was however smaller than in other years this temporary decrease may be caused by an altered innovation subsidy scheme in crisis years or by a different innovation investment behavior of the subsidy recipients we do not find support for the countercyclical innovation subsidy scheme having caused the smaller additionality effect and conclude that it is likely to be driven by subsidy recipient behavior
