learning and wage dynamics we develop a dynamic model of learning about worker ability in a competitive labor market the model produces three testable implications regarding wage dynamics 1 although the role of schooling in the labor market s inference process declines as performance observations accumulate the estimated effect of schooling on the level of wages is independent of labor market experience 2 timeinvariant variables correlated with ability but unobserved by employers such as certain test scores are increasingly correlated with wages as experience increases and 3 wage residuals are a martingale we present evidence from the nlsy that is broadly consistent with the model s predictions

the dynamic behavior of wages and prices cointegration tests within a large macroeconomic system the dynamic relationship between wages and prices has long held a central place within the economic literature most macroeconomic models make assumptions as to the causal relationship between the two variables unfortunately empirical investigations have produced widely divergent results in particular the present paper examines the results of time series studies and argues that the lack of a consensus is due to improperly specified models once the wage price relationship is embedded within a multiple vector system identification of a wage price cointegrating relationship is significantly improved in addition the increased efficiency yields evidence in favor of the dual feedback between wages and prices

international technology transfer and the technology gap abstract we build a quality ladders product cycle model that explores how the quality of technology transferred through foreign direct investment fdi is linked to innovation and imitation when the absorptive capacity of ldcs is limited successful imitation of low quality levels makes fdi involving high quality levels possible through reduction of the technology gap a subsidy to imitation or a tax on low quality fdi production encourages imitation relative to innovation thus releasing the constraint faced by foreign firms seeking to produce in the south these forces that stimulate high quality fdi raise southern welfare through lower prices faster innovation and higher wages

production function regressions returns to scale and externalities a number of recent papers have used simple linear regressions in an attempt to identify market structure the extent of returns to scale and possible external effects in u s manufacturing industries the results obtained from these regressions have important implications for several branches of modern macroeconomics as a result the macro literature frequently cites specific numerical evidence from caballero and lyons 1992 and hall 1990 which suggests that there are quantitatively significant increasing returns to scale or external effects in u s manufacturing in contrast it is the argument of this paper that this evidence is not convincing the most robust evidence suggests that the typical u s manufacturing industry displays constant returns with no external effects on the other hand there is significant heterogeneity across industries

the liability of localness in innovation i analyze differences in the innovativeness of domestic firms and subsidiaries of foreign firms operating in the same country i argue that domestic firms suffer a liability of localness in innovation or a competitive disadvantage in product innovation relative to subsidiaries of foreign firms i propose that this liability of localness is driven by the relatively lower levels of multiculturalism in employees of domestic firms in comparison with subsidiaries which limit the identification transfer and integration of a large diversity of knowledge that supports product innovation i also propose that managers of domestic firms can compensate for this liability of localness in two ways by investing in the training of their employees and by exporting training modifies the mindsets and abilities of employees and enables them to become more cognitively multicultural which facilitates product innovation exporting changes employees mindsets as they become exposed to new ideas available abroad which also facilitates product innovation i test these arguments on a sample of manufacturing firms and find that although domestic firms introduce fewer new products than subsidiaries of foreign firms they introduce more new products than subsidiaries at the same level of investment in language training and of exports

the tangible contribution of r d spending foreign owned plants to a host region a plant level study of the irish manufacturing sector 1980 1996 abstract the rapid growth of the irish economy over the past decade and the simultaneous increase in i the number of foreign owned plants in the high tech sectors and ii the research and development r d activities of foreign owned plants have given rise to an increased interest in the relationship between foreign direct investment fdi and economic growth in ireland the central question explored in this paper is whether the tangible contribution of mnc plants which undertake r d investment in ireland is greater than the tangible contribution of mnc plants which undertake no r d investment we use a plant level data set and conclude that the scale of r d activity in a plant is an important determinant in i lengthening the duration over which that plant will remain in ireland and ii improving the quality of employment created in that plant although it has long been recognised that the attraction of fdi to ireland has been beneficial the results of this paper support the idea that r d active firms generally provide greater benefit to the economy on employment grounds alone policy should favour r d active plants in high tech sectors

job change patterns and the wages of young men this study uses data from the national longitudinal survey of youth to distinguish empirically between mover stayer search good and experience good models of job mobility we estimate wage models in which the pattern of overall job mobility affects both the level and tenure slope of the log wage path after controlling for the correlation between mobility patterns and time constant person and job specific unobservables we find that workers who undergo persistent mobility have lower log wage paths than less mobile workers this finding is consistent with models in which job mobility is driven by time varying unobservables such as experience good models where changes in perceived match quality cause turnover

measures of technology and the business cycle empirical evidence on the relationship between technology shocks and e g hours worked hinges crucially on the identification of the unobservable technological progress in this paper we study different measures of technology in order to find out i to what extent they capture the same underlying phenomenon and ii whether the implications for macroeconomic theory are robust across the approaches several versions of the productions function approach and structural var models are investigated our main finding is that the different technology measures are highly correlated however the exact formulation of the identifying restrictions seems to matter for the results while we replicate the standard finding of a strongly procyclical solow residual all other measures of technology are either acyclical or countercyclical

comparative advantage learning and sectoral wage determination we develop a model in which a worker s skills determine the worker s current wage and sector the market and the worker are initially uncertain about some of the worker s skills endogenous wage changes and sector mobility occur as labor market participants learn about these unobserved skills we show how the model can be estimated using nonlinear instrumental variables techniques we apply our methodology to study wages and allocation of workers across occupations and industries using individual level panel data from the national longitudinal survey of youth we find that high wage sectors employ high skill workers and offer high returns to workers skills

rule of thumb consumers productivity and hours in this paper we study the transmission mechanism of productivity shocks in a model with rule of thumb consumers in the literature this nancial friction has been studied only with reference to scal shocks we show that the presence of rule of thumb consumers is also very helpful in accounting for recent empirical evidence on productivity shocks rule of thumb agents together with nominal and real rigidities play an important role in reproducing the negative response of hours and the delayed responses of output and

on real and sticky price theories of the business cycle after presenting some facts about the growth of government in western industrialized countries possible causes of this development are analyzed from a public choice perspective next some empirically tested theories which seek to explain this growth are discussed finally possible consequences for efficiency and individual liberty are examined it is shown that both the number and size of interest groups age of democracy as stated by mancur olson 1982 and the increasing share of government expenditure in gdp seem to exert a negative influence on the growth rate of gdp copyright 1986 by ohio state university press

foreign direct investment competition and industrial development in the host country this paper analyses the impact of foreign direct investment fdi on the development of local firms we focus on two likely effects of fdi a competition effect which deters entry of domestic firms and positive market externalities which foster the development of local industry using a simple theoretical model to illustrate how these forces work we show that the number of domestic firms follows a u shaped curve where the competition effect first dominates but is gradually outweighed by positive externalities evidence for ireland tends to support this result specifically applying semi parametric regression techniques on plant level panel data for the manufacturing sector we find that while the competition effect may have initially deterred local firms entry this initial effect has been outpaced by positive externalities making the overall impact of fdi largely positive for the domestic industry

an equilibrium analysis of wage productivity gaps we develop a model in which each firm chooses a hiring standard as well as a wage schedule and an application fee we then characterize the set of nash equilibria and establish necessary and sufficient conditions for the existence of equilibrium if the distribution of productivities within each ability type is gaussian workers who pass the test will be paid more than the value of their marginal product while workers who fail the test will receive a wage net of the application fee below the value of their marginal product

industry specific capital and the wage profile evidence from the national longitudinal survey of youth and the panel study of income dynamics using data from the national longitudinal survey of youth 1979 96 and the panel study of income dynamics 1981 91 i seek to determine whether there is any net positive return to tenure with the current employer once we control for industry specific capital including total experience in the industry as an additional explanatory variable i show that the return to seniority is markedly reduced using gls while it virtually disappears using iv gls at both the one digit and three digit levels therefore it seems that what matters most for the wage profile in terms of human capital is industry specificity not firm specificity

real wages over the business cycle evidence from panel data one topic on which keynes did not disagree with classical economists was the cyclical behavior of real wages keynes 1936 as well as various classical writers predicted that real wages should move countercyclically quoting the general theory p 17 in general an increase in employment can only occur through the accompaniment of a decline in real wages thus i am not disputing this vital fact which the classical economists have rightly asserted as indefeasible this prediction is based on the premise of competition and a given short run capital stock increases in employment then correspond to more intensive use of capital and through diminishing product lower real wages for this reason evidence by dunlop 1938 and tarshis 1939 that real wages move procyclically was viewed as paradoxical both dunlop and tarshis based their findings on an observed positive correlation between real and money wages which given the procyclical movement of money wages implies a positive correlation between

new business formation in a rapidly growing economy the irish experience the extraordinary growth of the irish economy since the mid 1990s the celtic tiger has attracted a great deal of interest commentary and research indeed many countries look to ireland as an economic development role model and it has been suggested that ireland might provide key lessons for other eu members as they seek to achieve the objectives set out in the lisbon agenda much of the discussion of ireland s growth has focused on its possible triggers the long term consequences of the late 1980s fiscal stabilisation eu structural funds education wage moderation and devaluation of the irish punt the industrial policy perspective has highlighted the importance of inflows of foreign direct investment but a notable absence from the discourse on the celtic tiger has been any mention of the role of new business venture creation and entrepreneurship in this paper we use unpublished irish vat data for the years 1988 2004 to provide the first detailed look at national trends in business birth and death rates in ireland over the take off period we also use sub national vat data to shed light on spatial trends in new venture creation our overall conclusions are that new business formation made no detectable contribution to the acceleration of ireland s growth in the late 1990s although we do find evidence of spatial convergence in per capita business stocks

price and investment dynamics theory and plant level data we construct a model of a firm competing for market share in a customer market and making investments in physical capital the firm is financially constrained and there are implementation lags in investment our model predicts that product prices should depend on costs and competitors prices but respond weakly to demand shocks also prices should be strongly related to investment we estimate price and investment equations on panel data for swedish manufacturing plants and find results that are qualitatively in line with these predictions though the relation between investment and prices is stronger than predicted by our model

real wages employment and the phillips curve a recent study by bils found real wages to be procyclical contradicting previous findings by geary and kennan who found no consistent relationship and neftci who found countercyclical movements in real wages these studies differed in both methodology and sample period in this study we found that real wages were either procyclical or countercyclical depending on the sample period chosen employment changes generated by aggregate supply shocks were associated with procyclical real wage movements while during years dominated by shifts in aggregate demand real wages were highly countercyclical

prices productivity and wage bargaining in open economies according to the standard union bargaining model unemployment benefits should have big effects on wages but product market prices and productivity should play no role in the wage bargain we formulate an alternative strategic bargaining model where labour and product market conditions together determine wages a wage equation is derived and estimated on aggregate data for four nordic countries wages are found to depend not only on unemployment and the replacement ratio but also on productivity international prices and exchange rates there is evidence of considerable nominal wage rigidity exchange rate changes have large and persistent effects on competitiveness

sectoral shifts and cyclical unemployment a substantial fraction of cyclical unemployment is better characterized as fluctuations of the frictional or natural rate than as deviations from some relatively stable natural rate shifts of employment demand between sectors of the economy necessitate continuous labor reallocation since it takes time for workers to find new jobs some unemployment is unavoidable this paper presents evidence that most of the unemployment fluctuations of the seventies unlike those in the sixties were induced by unusual structural shifts within the u s economy simple time series models of layoffs and unemployment are constructed that include a measure of structural shifts within the labor market these models are estimated and a derived natural rate series is constructed

a theory of wage dynamics a dynamic equilibrium model of long term implicit labour contracts under incomplete but symmetric information is developed workers are assumed to be risk averse and of unknown ability or productivity risk neutral firms learn as do workers about each worker s productivity by observing the worker s output over time it is shown that equilibrium contracts provide for wages which never decline with age and increase only when the worker s market value increases above his current wage in addition to characterizing the equilibrium wage contract we also derive some of its implications for the behaviour of aggregate wages across various groups of workers these implications explain some findings in the recent empirical literature on ageearnings profiles in particular our model can explain why earnings may be positively related to experience even after controlling for productivity as some empirical studies have indicated

a dynamic analysis of educational attainment occupational choices and job search this article examines career choices using a dynamic structural model that nests a job search model within a human capital model of occupational and educational choices wage growth occurs in the model because workers move between firms and occupations as they search for suitable job matches and because workers endogenously accumulate firm and occupation specific human capital simulations performed using the estimated model reveal that both self selection in occupational choices and mobility between firms account for a much larger share of total earnings and utility than the combined effects of firm and occupation specific human capital

inventories as factors of production and economic fluctuations this paper presents a theory of inventory investment by stage of processing and uses it to examine the role of inventory investment in economic fluctuations the model in which inventories are treated as factors of production is estimated for four durable goods industries three conclusions emerge from the estimation first the estimates generally satisfy the theoretical restrictions second the elasticity of inventory demand with respect to output is high indicating an important accelerator effect finally the estimates suggest that shifts in the demand for inventories are an important source of economic fluctuations copyright 1989 by american economic association

learning your comparative advantages we introduce an equilibrium labor market model where workers gradually learn about their unobserved production abilities while engaged in a productive activity occupation workers observe their output and extract information that allows them to make inferences about their unobserved aptitudes because workers are learning about themselves their output informs them not only about their productivity in their current occupation but about their likely productivity in other occupations as well as workers acquire more information they self select into the occupations in which they expect to perform best and their wages increase returns to experience here capture improved job selection by workers as they sort through occupations and learn

the impact of foreign direct investment on new firm survival in the uk evidence for static versus dynamic industries the paper examines the impact of foreign direct investment fdi on the survival of business start ups fdi has potential for both negative displacement competition effects as well as positive knowledge spillover and linkage effects on new ventures we find a net positive effect for the whole dataset however a major contribution of the paper is to outline and test an argument that this effect is likely to be comprised of a net negative effect in dynamic industries high churn firm entry plus exit relative to the stock of firms alongside a net positive effect in static low churn industries we find evidence to support this view the results identify new effects of globalisation on enterprise development with associated challenges for industrial policy

market efficiency and cointegration an application to the sterling and deutschemark exchange markets abstract the assumption that the foreign exchange market is efficient that is that agents are risk neutral and use all available information rationally so that the forward exchange rate is an unbiased predictor of the future spot rate is a property often imposed in theoretical international macroeconomic models although a vast empirical literature has evolved to test market efficiency we use recent developments in the theory of cointegration to provide new methods of testing several aspects of foreign exchange market efficiency we ffind evidence inconsistent with market efficiency for both germany and the united kingdom

factor hoarding and the propagation of business cycles shocks this paper analyzes the role of variable capital utilization rates in propagating shocks over the business cycle to this end we formulate and estimate an equilibrium business cycle model in which cyclical capital utilization rates are viewed as a form of factor hoarding we find that variable capital utilization rates substantially magnify and propagate the impact of shocks to agents environments the strength of these propagation effects is evident in the dynamic response functions of various economy wide aggregates to shocks in agents environments in the statistics that we construct to summarize the strength of the propagation mechanisms in the model and in the volatility of exogenous technology shocks needed to explain the observed variability in aggregate u s output other authors have argued that standard real business cycle rbc models fail to account for certain features of the data because they do not embody quantitatively important propagation mechanisms these features include the observed positive serial correlation in the growth rate of output the shape of the spectrum of the growth rate of real output and the correlation between the forecastable component of real output and various other economic aggregates allowing for variable capital utilization rates substantially improves the ability of the model to account for these features of the data

the relative adjustment of wages and prices direct tests within a multiple equation system in order to assess the relative rigidity of the aggregate price level and the nominal wage rate most researchers have focused on the implied behaviour of the real wage rate in response to a purely demand disturbance the present work examines the explicit behaviour of the two variables and is therefore able to analyse the variables short run responses within the context of their defined long run behaviour while the paper reports evidence of long run stability in the real wage rate additional evidence is presented which supports both sticky price and sticky wage models the determining factor is the choice of lag

new firm survival new results using a hazard function a limitation of audretsch s 1991 study of new firm survival was the level of aggregation to industries this precluded linking establishment specific characteristics such as organizational structure and size to post entry performance the purpose of this paper is to relate the post entry performance of individual establishments not only to their technological and market structure environments but also to establishment specific characteristics we do this by estimating a hazard duration function for more than 12 000 individual establishments in u s manufacturing started in 1976 by tracking their subsequent performance over a ten year period we conclude that establishment specific characteristics which audretsch was not able to capture in his earlier study play an important role in shaping the exposure to risk confronting new establishments copyright 1995 by mit press

what should i be when i grow up occupations and unemployment over the life cycle abstract why is unemployment higher for younger individuals we address this question in a frictional model of the labor market that features learning about occupational fit in order to learn the occupation in which they are most productive workers sample occupations over their careers because young workers are more likely to be in matches that represent a poor occupational fit they spend more time in transition between occupations through this mechanism our model can replicate the observed age differences in unemployment which as in the data are due to differences in job separation rates

the relation between price and marginal cost in u s industry an examination of data on output and labor input reveals that some u s industries have marginal cost well below price the conclusion rests on the finding that cyclical variations in labor input are small compared with variations in output in booms firms produce substantially more output and sell it for a price that exceeds the costs of the added inputs the paper documents the disparity between price and marginal cost where marginal cost is estimated from annual variations in cost it considers a variety of explanations of the findings that are consistent with competition but none is found to be completely plausible

understanding the city size wage gap in 2000 wages of full time full year workers were more than 30 percent higher in metropolitan areas of over 1 5 million people than rural areas the monotonic relationship between wages and city size is robust to controls for age schooling and labor market experience in this paper we decompose the city size wage gap into various components we propose an on the job search model that incorporates latent ability search frictions firm worker match quality human capital accumulation and endogenous migration between large medium and small cities counterfactual simulations of the model indicate that variation in returns to experience and differences in wage intercepts across location type are the most important mechanisms contributing to the overall city size wage premium steeper returns to experience in larger cities is more important for college graduates while differences in wage intercepts is more important for high school graduates sorting on unobserved ability within education group and differences in labor market search frictions and distributions of firm worker match quality contribute little or slightly negatively to observed city size wage premia in both samples

production growth and business cycles ii new directions abstract this paper outlines new directions for investigations of real business cycle models consideration of stochastic growth of exogenous and endogenous forms analysis of suboptimal outcomes arising due to externalities of distorting taxes and implications of labor market heterogeneity

political cycles and cyclical policies we test how government revenue and expenditure depend on ideology elections and economic activity we show how fiscal forecasts can be used to identify the determinants of government revenue and expenditure the approach is illustrated using a unique unpublished swedish data set of fiscal forecasts and forecasts of economic activity we find partisan effects but no election effects revenue and expenditure but also the fiscal surplus are lower with right wing governments fiscal policy has been countercyclical revenue varies positively with nominal earnings expenditure varies negatively with real gdp

the specificity of general human capital evidence from college major choice college graduates do not always pursue careers related to their major science majors working in jobs unrelated to their field of study earn approximately 30 lower wages than those working in related jobs we develop a structural model of major choice and labor market outcomes that allows for skill uncertainty and differential accumulation of human capital across major our findings confirm that the average return to obtaining a science degree and working in a related job remains close to 30 we also find that individuals are uncertain about their future productivity at the time of the college major decision

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

do wages rise with job seniority many previous studies have found a strong positive effect of job seniority tenure on wages this paper re examines the evidence using a simple instrumental variables scheme to deal with the fact that tenure is likely to be related to unobserved individual and job characteristics that affect the wage we use the variation of tenure over a given job match as the principal instrumental variable for tenure the variation in tenure over the job is uncorrelated by construction with the fixed individual and job match specific components of the error term of the wage equation our main finding is that the partial effect of tenure on wages is small and that general labour market experience and job shopping account for most wage growth over a career the strong cross section relationship between tenure and wages is due primarily to heterogeneity bias prior researchers see mincer and jovanovic 1981 bartel and borjas 1981 borjas 1981 cline 1979 and mellow 1981 and many others have established that job seniority has a strong positive relationship with wage rates in a cross section or a cross section time series of individuals in this paper we re evaluate the evidence concerning the partial effects on wages of job seniority tenure and total labour market experience the extent to which wages rise with tenure is important for several reasons first and foremost the wage tenure profile is a fundamental question about the structure of earnings over careers second the wage tenure profile is a key determinant of the extent to which the earnings power of individuals is tied to specific jobs and it is important for assessment of the losses suffered by displaced workers hamermesh 1984 third evidence that wages rise with job tenure has been used to explain the decline in quits with tenure since the wage growth on the current job lowers the probability that the worker will locate a superior alternative a growing theoretical literature surveyed in parsons 1984 has taken the evidence of a strong wage tenure profile at face value and sought to provide an explanation for the relationship the most prominent explanation is the theory of specific human capital oi 1962 becker 1962 mincer 1974 parsons 1972 kuratani 1973 and hashimoto 1980 in which the growth of wages with tenure holding experience constant is attributed to the worker s share of investments in firm specific skills more recently lazear 1981 has presented a supervision model of wage growth in which firms defer compensation as a means of inducing workers not to shirk freeman 1977 and harris and holmstrom 1982 provide an explanation for wage growth based on an insurance motive salop and salop 1976 nickell 1976 and guasch and weiss 1982 present adverse selection models of wage growth in which firms use a wage tenure profile as a

labor hoarding and the business cycle this paper investigates the sensitivity of solow residual based measures of technology shocks to labor hoarding behavior using a structural model of labor hoarding and the identifying restriction that innovations to technology shocks are orthogonal to innovations in government consumption we estimate the fraction of the variability of the solow residual that is due to technology shocks our results support the view that a significant proportion of movements in the solow residual are artifacts of labor hoarding behavior specifically we estimate that the variance of innovations to technology is roughly 50 percent less than that implied by standard real business cycle models in addition our results suggest that existing real business cycle studies substantially overstate the extent to which technology shocks account for the variability of postwar aggregate u s output

the contributions of search and human capital to earnings growth over the life cycle abstract this paper presents and estimates a unified model where both human capital investment and job search are endogenized this unification enables us to quantify the relative contributions of each mechanism to life cycle earnings growth while investigating potential interactions between human capital investment and job search within the unified framework the expectation of rising rental rates of human capital through job search gives workers more incentive to invest in human capital in addition unemployed workers reduce their reservation rental rates and increase their search effort to leave unemployment quickly to take advantage of human capital accumulation on the job the results show both forces are important for earnings growth and the interactions are substantial human capital accumulation accounts for 50 of total earnings growth job search accounts for 20 and the remaining 30 is due to the interactions of the two

human capital specificity evidence from the dictionary of occupational titles and displaced worker surveys 1984 2000 measures of four basic skills constructed from the dictionary of occupational titles are used to examine the source of human capital specificity the measures are used to characterize the skill portfolio of each job and to construct distance measures between jobs wage losses in the displaced worker surveys are shown to be more closely associated with switching skill portfolios than switching industry or occupation code per se these switches represent large decreases in the skill portfolio in the postdisplacement job the recent evidence for industry specific capital is reexamined the results suggest a difference between fluid and crystallized skills

technology transfer and spillovers does local participation with multinationals matter this paper examines the effects on technology transfer and spillovers deriving from ownership sharing of foreign multinational affiliates more specifically we try to answer two questions using unpublished indonesian micro data firstly do establishments with minority and majority ownership differ in terms of productivity levels secondly does the degree of spillover differ with the degree of ownership in the fdi our results show that foreign establishments have comparable high levels of labor productivity and that domestic establishments benefit from spillovers however the degree of foreign ownership does neither affect the level of labor productivity in foreign establishments nor the degree of spillovers

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

the survival of new plants start up conditions and post entry evolution abstract this paper examines the longevity of entrants we find size to be an important determinant of the chances of survival this being particularly relevant to de novo entrants as compared with entry by established firms current size is also found to be a better predictor of failure than initial size moreover our findings indicate that after controlling for size differences past growth matters for survival suggesting a partial adjustment process for firm size in the post entry period finally new plants are more likely to live longer if they enter growing industries or industries with little entry activity

real wages and the business cycle the objectives of this review are threefold 1 to characterize the empirical literature on the cyclical behavior of real wages 2 to identify the sources of the differences in results across studies and 3 to enumerate key factors that determine the cyclicality of real wages given a host of measurement and methodological issues drawing firm conclusions is difficult but several generalizations can be made the estimated cyclicality of real wages depends crucially on the time period of analysis and the choice of whether to examine the production or the consumption wage composition effects play an important but complicated role as well

the relative stickiness of wages and prices i introduction a continuing challenge to macroeconomics is to explain how a purely nominal disturbance produces short term aggregate real effects in the classical paradigm in which wages and prices are perfectly flexible a positive nominal aggregate demand disturbance will cause nominal wages and output prices to rise in the same proportion leaving real wages unchanged thus neither employment nor output will be affected consequently many business cycle theories posit the existence of wage and or price stickiness to explain how nominal aggregate demand disturbances generate real macroeconomic effects according to these theories the failure of nominal wages or prices to fully adjust in the short run to purely nominal disturbances explains why shocks to aggregate demand will cause both employment and output to temporarily deviate from their natural rates the relative importance of wage and price stickiness in the transmission of nominal shocks to the real economy however remains an unsettled issue the purpose of this paper is to exploit evidence on the behavior of real wages in an attempt to assess the relative importance of these two sources of stickiness first consider models emphasizing sticky or slowly adjusting nominal wages 1 if for example output prices are free to adjust but nominal wages are sticky a positive aggregate demand shock will cause prices to rise and real wages to temporarily fall below market clearing levels the fall in real wages will stimulate employment and thus output as the aggregate demand shock induces movement along a stable labor demand curve consequently sticky wage models predict a negative correlation between aggregate demand shocks and real wages if on the other hand wages are flexible while output prices are sticky 2 aggregate demand disturbances and real wages will tend to be positively correlated in the short run in sticky price models imperfectly competitive firms may resist adjusting output prices in response to changes in demand perhaps due to menu costs instead increases in demand are met by corresponding increases in output this requires an increase in labor inputs which in turn requires an increase in the real wage rate if wages are flexible and the labor supply curve is positively sloped thus when prices are sticky but wages are flexible a positive aggregate demand shock is associated with an increase in real wages it may be that neither prices nor wages are fully flexible if prices and wages both exhibit stickiness we would expect real wages to be positively correlated or negatively correlated with aggregate demand shocks depending in large part on whether prices or wages are stickier thus knowledge of the direction of the short run response of real wages to aggregate demand disturbances would offer important evidence on the relative stickiness of nominal wages and output prices if all business cycle fluctuations are due solely to aggregate demand disturbances such evidence could be obtained by examining the cyclical behavior of real wages since regardless of the source of stickiness aggregate demand disturbances are positively correlated with employment and output countercyclical procyclical real wages would indicate that nominal wages are stickier more flexible than output prices indeed some consider the stylized fact of slightly procyclical real wages 3 to be an important challenge to models that emphasize wage stickiness for example bennett mccallum 1986 argues for the superiority of models with sticky output prices since if wage stickiness alone were responsible for the real effects of monetary actions with product prices adjusting flexibly then we should observe countercyclical movements in the real wage that we do not has recently been reconfirmed in a study by bils 1985 gregory mankiw 1987 107 has concluded the final and perhaps most serious problem with the unadorned nominal wage story is that real wages do not move over the business cycle as the theory predicts

career choice and wage growth in this article i present structural estimates of a search model that flexibly incorporates general human capital accumulation along with career and firm choice where a career is empirically identified as a combination of industry and occupation i use these estimates to empirically distinguish between the relative importance of various factors for generating wage growth over the life cycle evidence presented in the article highlights the importance of considering the two stage search process that originates from the model in particular i demonstrate that previous instrumental variables methods dramatically underestimate the importance of firm specific matches for wage growth

the costs of occupational mobility an aggregate analysis we estimate the costs of occupational mobility using a novel approach that relies on aggregate flows of workers across occupations rather than on wage data the theoretical underpinnings for this approach are derived from a model of occupation choice that delivers a gravity equation linking worker flows to occupation characteristics and to transition costs which we proxy using task data from the dictionary of occupational titles dot occupation flow data are constructed from the matched monthly current population survey cps between 1994 and 2012 we find that transition costs vary widely across occupations are increasing in task distance the dissimilarity in the mix of tasks performed in the two occupations and are higher for transitions across broad task categories however most of the transition costs are accounted for by general task independent entry costs specific to each destination occupation

mnes and industrial structure in host countries a portfolio analysis of irish manufacturing ireland has been very successful in attracting foreign mnes in high technology sectors although these sectors exhibit faster growth than the traditional low technology sectors populated primarily by indigenous firms the high technology sectors are also more volatile we use portfolio theory to show that ireland s fdi strategy has led to a more diversified manufacturing sector that exhibits higher growth without a commensurate increase in volatility and risk

multinational companies technology spillovers and plant survival how does the presence of multinational companies affect plant survival in the host country we postulate that multinational companies can impact positively on plant survival through technology spillovers we examine the nature of the effect of multinationals using a cox proportional hazard model which we estimate using plant level data for irish manufacturing industries our results show that the presence of multinationals has a life enhancing effect only on indigenous plants in high tech industries suggesting the presence of technology spillovers in contrast multinationals compete with each other in low tech sectors in the host country

job matching and occupational choice this paper presents a model of job matching the generalizes the existing literature by allowing for different jobs types or occupations such differences affect the value of job specific experience inducing a career profile where certain types are sampled before others more specifically the analysis shows that it is optimal for the young and inexperienced to gravitate toward jobs exhibiting a certain kind of risk then after deriving the equilibrium job turnover rate for an economy in which people do not switch occupations panel data are used to estimate its underlying parameters the hypothesis that people do not switch occupations is rejected against the alternative that they do thus providing empirical support for the theoretical extension undertaken here

technology shocks and the labor input response evidence from firm level data we study the relationship between technology shocks and labor input on swedish firm level data using a production function approach to identify technology shocks taking standard steps yields a contractionary contemporaneous labor input response in tine with previous studies this finding may however be driven by measurement errors in the labor input variable relying on a unique feature of our data set which contains two independently measured firm specific labor input measures we can evaluate the potential bias we do not find that this bias conceals any true positive contemporaneous effect the results thus point away from standard flexible price models and toward models emphasizing firm level rigidities
