workforce reorganization and the worker in this article we study the joint decision process of changing the structure of jobs and laying off individual workers in a firm that downsizes its workforce a hierarchical decision model is proposed and estimated using personnel data from a firm in demise comparing the characteristics of the individual workers and the structure of the firm s labour force before and after its reorganization our results show that workers in jobs in the top levels of each skill group s hierarchy are better protected against downsizing due to larger productivity shocks and larger firing costs

what happens to wages after displacement faced with limited resources policymakers need to know when and where to target support for displaced workers the academic literature offers little support presenting wide ranging results with no consistent explanation for the observed differences in wages after workers are displaced in this paper we demonstrate that the heterogeneity found in the literature is consistent with varying market conditions the results suggest that support for displaced workers can be more efficiently allocated by considering the timing and location of displacement

aspects of labor market adjustments in japan this article discusses some aspects of labor market adjustments in japan that may be relevant to the low unemployment rate there japanese statistics treat kyugyosha persons not at work as being employed but some of these workers would be counted as unemployed in the united states the kyugyosha group appears to increase in size during downturns and decreases during upturns suggesting that temporarily laid off persons are an important part of this group japanese employers evidently rely less on employment adjustments and more on adjustments in hours of work and inventory while employers in the united states rely more on employment adjustments to deal with cyclical changes in product demand japanese manufacturing employment became less sensitive and hours of work more sensitive to demand shocks after the introduction of the employment insurance law in 1975

do contracts matter in canada this paper empirically examines the view that wage rigidity in long term labor contracts matters for the behavior of employment in particular i follow bils s 1991 approach which looks for systematic employment patterns in the first year of long term contracts using a new panel data set which includes annual firm level employment observations from the canadian manufacturing sector i find evidence in many industries that employment over adjusts to shocks that occur during the contract my examination of wage dynamics however indicates that for those industries in which contracts appear to matter for the behavior of employment there is little indication that contractual wage rigidity is the source of the over adjustment of employment

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

factor demand models with nonlinear short run fluctuations abstract this paper considers asymmetric costs of adjustment that propagate nonlinear shortrun fluctuations in stochastic factor demand systems the model endogenously generates asymmetric cyclical demand for capital and labour between peaks and troughs of the business cycle the empirical analysis of the model is based on quarterly time series data of the dutch manufacturing sector for the period 1971 i 1984 iv and annual time series data of the u k manufacturing sector for the period 1955 1986 i find important differences of adjustment speed of capital and labour inputs between expansionary and contractionary phases of the business cycle

adjustment costs inventories and output this paper analyzes the optimal adjustment strategy of an inventory holding firm facing price and quantity adjustment costs in an inflationary environment the model nests both the original menu cost model that allows production to be costlessly adjusted and the later model that includes price and quantity adjustment costs but rules out inventory holdings it is shown that the firm s optimal adjustment strategy may involve stockouts at low inflation rates output is inversely related to the inflation rate and the length of time demand is satisfied increases with the demand elasticity but decreases with the storage cost and the real interest rate

a flexible specification of adjustment costs in dynamic factor demand models this paper proposes a flexible form of adjustment cost function an empirical illustration shows that the flexible form can detect both convex and non convex adjustment costs furthermore the flex

finance and employment evidence from u s banking reforms abstract economic theory offers competing hypotheses about how the cost and availability of finance influence labor market outcomes making use of the u s banking reforms between the 1970s and the 1990s as a quasi natural experiment this paper studies the impact of credit market development on employment this paper documents the significant effects of these reforms on employment growth potential channels between finance and employment are also investigated changes in the growth of the number of self employed individuals the entry and exit of firms and investment growth do not explain most of the employment growth following the reforms the reforms had a substantially higher impact in industries with higher labor intensity which is consistent with the idea that labor has fixed costs that need to be financed

migration regional equilibrium and the estimation of compensating differentials in this study we have developed an improved model of net migration that encompasses both equilibrium and disequilibrium components instrumental variables fixed effects estimates of the model with time series data for 51 areas in the united states over the period 1971 1988 support the importance of both equilibrium and disequilibrium factors in migration excerpt

liabilities of regional foreignness and the use of firm level versus country level data a response to dunning et al 2007 we are pleased that dunning et al have provided macro country level data demonstrating the increased internationalization of many nations over the past decade we also appreciate their findings lending support to our perspective on the regional nature of world business our work was based solely on micro firm level data both country level data and firm level data have methodological problems which we attempt to reconcile in this commentary we also address the broader conceptual issues of how to interpret country level vs firm level data

war and pestilence as labor market shocks u s manufacturing wage growth 1914 1919 there is not a single expert machinist in the labor market today if such a one exists he will be able to command his own wages the arkansas gazette october 22 1918 1 i introduction the possibility of a worldwide influenza pandemic in the near future is of growing concern for many countries around the globe the world bank estimates that a global influenza pandemic would cost the world economy 800 kill tens of millions of people 2 researchers at the u s centers for disease control and prevention calculate that deaths in the united states could reach 207 000 and the initial cost to the economy could approach 166 billion or roughly 1 5 of gdp 3 the u s department of health and human services paints a more dire picture up to 1 9 million dead in the united states and initial economic costs near 200 billion 4 while researchers and public officials can only speculate on the likelihood of a global influenza pandemic many of the worst case scenario predictions for a current pandemic are based on the global influenza pandemic of 1918 this global pandemic often termed the spanish flu killed 675 000 people in the united states nearly 0 8 of the 1910 population and nearly 40 million people worldwide 5 only the black death of 13481351 is estimated to have killed more people roughly 60 million over a similar time period 6 the global magnitude and spread of the 1918 influenza pandemic was exacerbated by world war i which itself is estimated to have killed roughly 10 million civilians and 9 million troops nicolson 1980 not only did the mass movement of troops from around the world lead to the spread of the disease tens of thousands of allied and central power troops died as a result of the influenza rather than combat although combat deaths in world war i did increase the mortality rates for participating countries civilian mortality rates from the 1918 influenza were typically much higher for the united states estimates of combat related troop mortalities are about one tenth that of civilian mortalities from the 1918 influenza given the magnitudes and the concurrence of both the 1918 influenza pandemic and world war i one would expect volumes of research on the economic effects of each event although there does exist a significant literature on the economic consequences of world war i rockoff 2004 the scope of published research on the economic effects of the 1918 influenza pandemic is scant 8 most research that has been done has focused on the health and economic outcomes of decedents of pandemic survivors almond 2006 keyfits and flieger 1968 and mortality differences across socioeconomic classes mamelund 2006 noymer and garenne 2000 this paper contributes to the literature on the economic effects of the 1918 influenza pandemic and world war i by exploring the influence of mortalities from these concurrent events on the growth of manufacturing wages in u s states and cities over the period 1914 1919 9 the general conceptual foundation for the paper is that ceteris paribus both of these events resulted in a large number of deaths which constituted a significant negative shock to manufacturing labor supply and thereby would have increased wages in the manufacturing sector immediately following both events a similar conceptual framework has been used in studies that explored the economic effects of the black death campbell 1997 karakacili 2004 and the effects of immigration on labor markets borjas 1987 card 1990 greenwood and mcdowell 1986 the analysis presented here is the first to separate the potential manufacturing labor market effects of world war i and the 1918 influenza this is an interesting exercise given that mortalities from the 1918 influenza were nearly ten times greater than world war i combat mortalities but world war i combat mortalities were more likely men aged roughly 18 44 prime ages for manufacturing workers

capitalization and the theory of local public finance the tiebout literature is incomplete this paper argues because it has not fully accounted for the capitalization of local fiscal variables into house values the paper explains why capitalization arises why it persists in long run equilibrium how it affects both residential location and the outcome of local voting and why it interferes with the efficiency of a system of local governments the analysis which is based on the main tiebout assumptions plus a property tax combines a model of household bids in a housing market with a median voter model of local public service determination

learning by doing vs learning about match quality can we tell them apart understanding the accumulation of match specific capital is crucial in shedding light on the reasons for the prevalence of long term employ ment relationships and on the welfare consequences of turnover in the labor market one of the most important source of match specific capital is human capital acquired through match specific learning such learn ing can take on two distinct forms in the first case workers accumulate match specific human capital through learning by doing in the second case a worker and a firm in an employment relationship learn about the quality of the match over time thereby acquiring valuable information i construct a structural model that embeds these two learning explana tions i show that it is possible to distinguish the two explanations given turnover data on employing firms coupled with data on workers such data now exist in the form of matched employer employee data sets i use a matched french data set to estimate the structural model using the efficient method of moments a simulation based estimation method i find that while learning by doing could be present in the first few months of an employment relationship learning about match quality dominates at tenures above half a year this finding has important consequences for economists understanding of the sources of match specific capital and for the desirability of policies that alter the incentives for turnover for workers of different tenure

partial adjustment without apology econometric partial adjustment models perform relatively well at the aggregate level however many kinds of microeconomic behavior involve discrete and occasional choices analyzing the classic employment adjustment problem we show how a generalized partial adjustment model tractably accommodates both observations by aggregating the actions of heterogeneous producers facing fixed adjustment costs aggregate disturbances cause changes in establishment level target employment and in the measure of establishments actively adjusting to their target whereas aggregate responses exhibit partial adjustment our framework also can be applied in general equilibrium settings with persistent idiosyncratic shocks without forfeiting the convenient use of linear solution methods

the global integration of business functions a study of multinational businesses in integrated global industries the way that multinational businesses in integrated global industries coordinate and control r d manufacturing and marketing functions across borders has significant implications for performance we propose that in such global industries certain integrating modes will be more effective than others in integrating a function globally we show that each function has a different combination of effective integrating modes for global r d integration people based and information based modes are more effective than formalization based and centralization based modes for manufacturing people information and formalization are more effective than centralization with respect to marketing information and centralization are more effective than people and formalization we also demonstrate that the co alignment between actual and ideal profiles configurations or patterns of integrating modes results in superior performance our results reveal that people based and information based modes are generally more effective than formalization based and centralization based modes in coordinating and controlling business functions worldwide

employment dynamics and the structure of labor adjustment costs in this article we document the patterns of employment adjustment at the micro level we find clear evidence of lumpy adjustment consistent with the presence of nonconvexities in the adjustment technology inaction is pervasive action spells are short lived and extreme adjustment episodes are responsible for a nontrivial share of employment adjustment we also find that the probability of employment adjustment increases with the duration of inaction the skill structure of the workforce the type of employment contract and the proportion of low tenure workers which we interpret as proxies for the magnitude of adjustment costs all influence the probability of adjustment

adjustment costs uncertainty and the level of activity what is the effect of adjustment costs on economic activity this is an important question that is still debated either at the political or the academic level we consider a simple model where basically two effects come into play adjustment costs decrease current activity but may help maintain future activity we examine their relative strength first in a model with uncertain prices and then in a model with demand uncertainty newsboy problem

the globalization of swedish mnes empirical evidence and theoretical explanations we define globalization as the geographical dispersion of multinational enterprises mnes value chain in combination with increased inter regional coordination and use detailed firm level data to show that 12 of sweden s 17 largest manufacturing companies indeed are global by developing a globalization process model we theoretically argue in contrast to much of the existing literature that globalization may evolve to a more general phenomenon the globalization process is tortuous as mnes have to develop dynamic capabilities which make them gradually more competitive and able to cope with varying institutional contexts empirical testing on globalization of mnes originating from other home countries is suggested

regional sorting of human capital the choice of location among young adults in sweden berck p tano s and westerlund o regional sorting of human capital the choice of location among young adults in sweden regional studies migration rates are highest among young adults especially students and their location choices affect the regional distribution of human capital growth and local public sector budgets using swedish register data on young adults the choice of whether to enrol in education and the choice of location are estimated jointly the results indicate a systematic selection into investment in further education based on school grades and associated preferences for locations with higher per capita tax bases for students the estimates indicate lower preferences for locations with higher shares of older people the importance of family networks for the choice of location is confirmed

labor adjustment costs in a destination country the case of mexico abstract rodrik rodrik d 1997 has globalization gone too far institute for international economics washington dc argues that firms use the threat of moving to low cost generally developing markets to make employment more flexible at home although a large literature documents significant adjustment costs in developed countries we know little about their size and importance in developing countries that receive capital we employ monthly mexican data from the gatt nafta period to estimate adjustment costs in mexico we consider adjustment costs for production and non production workers and allow for asymmetry while patterns of adjustment costs are similar as in developed countries adjustment costs in mexico are generally an order of magnitude smaller

factor adjustment spikes and interrelation an empirical investigation we take a descriptive look at interrelated factor demand starting from the observation that adjustment of capital and labor is lumpy we find that the adjustment dynamics of an input factor are affected by large adjustments in the other

labor market volatility in the search and matching model the role of investment specific technology shocks abstract shocks to investment specific technology have been identified as a main source of u s aggregate output volatility in this paper we present a model with frictions in the labor market and explore the contribution of these shocks to the volatility of labor market variables namely unemployment vacancies tightness and the job finding rate thus our paper contributes to a recent body of literature assessing the ability of the search and matching model to account for the large volatility observed in labor market variables to this aim we solve a neoclassical economy with search and matching where neutral and investment specific technologies are subject to shocks the three key features of our model economy are i firms are large in the sense that they employ many workers ii adjusting capital and labor is costly iii wages are the outcome of an intra firm nash bargaining problem between the firm and its workers in our calibrated economy we find that shocks to investment specific technology explain 40 of the observed volatility in u s labor productivity moreover these shocks generate relative volatilities in vacancies and the workers job finding rate which match those observed in u s data relative volatilities in unemployment and labor market tightness are 55 and 75 of their empirical values respectively

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

income segregation and local progressive taxation empirical evidence from switzerland this study investigates spatial income segregation in fiscally decentralized urban areas the theoretical part proposes the progressivity of local income taxes as a new theoretical explanation for income segregation the empirical part studies how income tax differentials across municipalities affect the households location decisions i use data from the swiss metropolitan area of basel that contains tax information on all moving households in 1997 the location choice of the households is investigated within the framework of the random utility maximization model different econometric specifications of the error term structure such as conditional logit nested logit and multinomial probit are compared the empirical results show that rich households are significantly and substantially more likely to move to low tax municipalities than poor households this result holds after controlling for alternative explanations of segregation social interactions and distance from the central business district are established as other major factors for income segregation households in general tend to choose locations close to other households like themselves

age specific dynamic labor demand and human capital investment abstract to study the optimal age specific labor demand and human capital investment at the firm level we extend the standard dynamic labor demand model by introducing age as a second dynamic variable and distinguish between two types of workers low skilled and high skilled applying an age structured optimal control model we derive qualitative features of the optimal age specific hiring and training effort for the case of a linear revenue and production function we prove that firms do not anticipate changes in adjustment costs in their optimal decisions this result no longer holds if a nonlinear revenue or production function is considered

housing demand and community choice an empirical analysis abstract housing demand reflects the household s simultaneous choice of the neighborhood whether to own or rent the dwelling and the quantity of housing services demanded existing literature emphasizes the final two factors but overlooks the choice of community this paper develops an econometric model that incorporates all three components and then estimates this model using a sample of tampa florida households incorporating community choice increases the price elasticity of demand and reduces the differential between white and comparable nonwhite households the results are robust to the inclusion of permanent income and taxes

adjustment costs and factor demands in canadian manufacturing industries the question of whether regional disparities in canada could arise as a result of nonconstant returns to scale and non identical production functions is examined this is accomplished by estimating and comparing the decision rules for factor demands across canadian regions the decision rules are based on a flexible and dynamic production technology which allows for the presence of internal adjustment costs do not impose constant returns to scale or require hours and workers to have the same output elasticities the model is estimated for four separate canadian regions ontario quebec the western and eastern provinces on annual data ranging from 1965 to 1985

a comment on the economics of labor adjustment mind the gap reply in earlier contributions ricardo j caballero and eduardo m r a engel 1993 hereafter ce and caballero et al 1997 hereafter ceh investigate labor dynamics using a methodology which postulates that employment changes depend on a gap between the actual and target levels of employment both studies find evidence of nonlinearities in aggregate timeseries data employment growth depends on the cross sectional distribution of employment gaps this finding is taken as evidence that nonlinear adjustment at the microeconomic level matters for aggregate time series this is important for business cycle and policy analysis as it implies macroeconomics must take the cross sectional distribution of employment gaps into account this paper questions the methodology and thus the conclusions of these studies we argue that these reported aggregate nonlinearities may be the consequence of mismeasurement of the gap rather than nonlinearities in plant level adjustment both ce and ceh rely upon a hypothesis that employment growth responds to a gap z between the desired and actual number of workers at a plant the advantage to the gap approach is that the choice of employment an inherently difficult dynamic optimization problem is characterized through a nonlinear relationship between and z that is the adjustment rate z is postulated to be a nonlinear function of z however there is no free lunch the desired number of workers and hence the employment gap is unobservable thus in order to confront data this approach needs an auxiliary theory to infer z from observed variables both ce and ceh use observed hours variations to infer the employment gap this inference is one element of our critique of the gap methodology to assess this methodology we simulate data from the solution of a dynamic model of labor adjustment assuming quadratic adjustment cooper department of economics university of texas austin tx 78712 e mail cooper eco utexas edu willis research department federal reserve bank of kansas city kansas city mo 64198 e mail jonathan willis kc frb org we are grateful to seminar participants at boston university emory university the university of british columbia the federal reserve bank of boston the university of haifa the university of iowa the university of michigan the university of pennsylvania the university of texas at austin the 2002 nber ef meeting and the 2000 cmsg conference at mcmaster university for comments and suggestions discussions with eduardo engel john haltiwanger daniel hamermesh peter klenow and christopher ragan were much appreciated the authors thank the nsf for financial support we also appreciate comments from the referees cooper thanks the federal reserve bank of minneapolis for its hospitality during revisions of this manuscript the views expressed herein are solely those of the authors and do not necessarily reflect the views of the federal reserve bank of kansas city the federal reserve bank of minneapolis or the federal reserve system 1 daniel hamermesh 1989 uses a gap methodology as well but does not adopt the approach of estimating a nonlinear hazard function explained below to infer the nature of adjustment costs hence we focus on ce and ceh in this discussion of methodology 2 we do not contest the general view of nonlinear employment adjustment at the plant level this finding is consistent with other evidence that points to inactivity as well as bursts of employment adjustment at the plant level for example hamermesh 1989 provides a revealing discussion of lumpy labor adjustment at a set of manufacturing plants steven davis and john haltiwanger 1992 document large employment changes at the plant level ceh also report evidence of inactivity in plant level employment adjustment there seems little doubt that an explanation of plant level employment dynamics requires a model of adjustment that is richer than the quadratic adjustment cost structure and includes some forms of nondifferentiability and or nonconvexity 3 as the gap approach is used in numerous other applications capital adjustment durable adjustment price adjustment to approximate the solution to dynamic optimization problems our concerns may be relevant for those exercises as well

output and welfare effects of inflation with costly price and quantity adjustments there exists by now a burgeoning literature concerned with the consequences of a fixed cost of price adjustment due to this cost a monopolistic firm does not necessarily adjust its price even though the current price deviates from the price that would maximize the firm s current profit as a result the production generally differs from what it would be in the absence of a menu cost with the effect of inflation on the average output and welfare under monopolistic competition being ambiguous and depending in a complicated way on the profit and demand functions 1 however one strong result holds unambiguously for all profit and demand functions at low inflation rates the average output and welfare are above their levels at full price stability where firms charge the static monopoly price 2 the driving force is that discounting makes a firm more concerned with its real profits earlier in a period with a constant nominal price than with its real profits later in the period in fact as the inflation rate approaches zero the firm s initial real price converges to the profit maximizing real price while the terminal real price converges to a smaller real price at low inflation rates therefore a firm s price is most of the time below the price that would maximize the current profit since output and welfare under monopolistic competition are inversely related to price average output and welfare are higher than under full price stability the inevitable conclusion is that the economy benefits from a little bit of inflation a critical assumption underlying this result is that firms can continuously adjust their production to satisfy demand so while the menu cost literature explicitly assumes that there is a small fixed cost incurred at each price adjustment it also implicitly assumes that it is costless to continuously adjust the quantity of output 3 this is however a questionable assumption there is some empirical evidence indicating the existence of a cost of quantity adjustment part of which is fixed in that it does not depend on the size of the adjustment 4 the cost of quantity adjustment stems from the need to rearrange and reorganize the factor inputs for the new level of production and includes managerial time and effort a fixed cost of quantity adjustment rules out any continuous adjustment of the production to satisfy the increasing demand that results from a decreasing real price within a period with a constant nominal price under the reasonable assumption that the menu cost does not exceed the fixed cost of quantity adjustment 5 in an inflationary environment a firm chooses to adjust its nomi

on the connections between intra temporal and intertemporal trades abstract this paper develops a new theory of international economics by introducing heckscher ohlin features of intra temporal trade into an intertemporal trade approach of current account to do so we consider a dynamic general equilibrium model with tradable sectors of different factor intensities which allows for substitution between intertemporal trade current account adjustment and intra temporal trade goods trade an economy s response to a shock generally involves a combination of a change in the composition of goods trade and a change in the current account flexible factor markets reduce the need for the current account to adjust on the other hand the more rigid the factor markets the larger the size of current account adjustment relative to the volume of goods trade and the slower the speed of adjustment of the current account towards its long run equilibrium we present empirical evidence consistent with the theory

economic theory and the world of practice a celebration of the s s model it was the question of how best to balance the costs of ordering and of running out of stock against the costs of holding excess inventory that inspired kenneth arrow theodore harris and jacob marschak to introduce the s s model in 1951 in this celebratory article we show how this model not only answered important practical questions but also opened the door to a quite startling range of important and challenging follow up questions many of great practical importance and analytic depth the s s model has become one of the touchstone models of economics opening new vistas of applied economic theory to all who internalize its structure today it is universally applied to solve questions faced in inventory control the core model elements uncertainty and fixed costs of adjustment are ubiquitous which has resulted in its becoming the general purpose economic model of discrete adjustment the s s model has also become a profound source of inspiration for macroeconomists seeking to understand the role that discrete microeconomic adjustments play in macroeconomic fluctuations looking forward we foresee rapid growth in the use of s s modeling to aid households making complex and costly financial decisions such as when and how to terminate a mortgage in the projected era of household operations research new modeling challenges will arise due to enriched feedback from the world of practice

how effective are level based r d tax credits evidence from the netherlands this paper examines the impact of the r d fiscal incentive program on r d by dutch firms taking a factor demand approach we measure the elasticity of firm r d capital accumulation to its user cost econometric models are estimated using a rich unbalanced panel of firm data covering the period 1996 2004 with firm specific r d user costs varying with tax incentives using the estimated user cost elasticity we perform a cost benefit analysis of the r d incentive program we find some evidence of additionality suggesting that the level based program of r d incentives in the netherlands is effective in stimulating firms investment in r d however the hypothesis of crowding out can be rejected only for small firms the analysis also indicates that the level based nature of the fiscal incentive scheme leads to a substantial social dead weight loss

employment and deadweight loss effects of observed nonwage labor costs i introduction nonwage labor costs consist of several mandated benefits health training accident housing plans as well as several taxes and are intended to increase workers welfare and job security however these benefits tend to come at the expense of reducing employment and deadweight losses to quantify these resulting effects one needs a reliable measure of the employment labor cost elasticity most studies conducted on this subject find low estimated values for this elasticity which contrasts with policy makers enthusiasm to reduce labor costs in this article using a peruvian matched firm workers data set we find that nonwage labor costs reduce employment measured in total hours of work by 17 for white collars and by 53 for blue collars with associated deadweight losses of 10 and 35 of total contributions revenues respectively we also compute employment losses of compliance with mandated employers and workers contributions of 4 for white collars and 12 for blue collars with respective associated deadweight losses of 2 and 6 of contribution revenues these results come from estimating the long run unconditional firm level labor demand function by a procedure that corrects for endogeneity of wages we show that unbiased estimates even using small units such as firm level data require not only that wages are exogenous but also that their unobserved determinants are uncorrelated with the unobserved determinants of labor demand this requirement is not fulfilled in the likely event pointed out by becker 1993 that larger firms are matched with more productive workers consequently an estimation that corrects for endogeneity yields a larger labor cost elasticity of labor demand than one that does not like ordinary least squares ols in the past two decades there has been intensive theoretical and empirical research on the effects of labor market frictions on job creation western european economies characterized by large job security provisions have been the center of attention of this research that has modeled these frictions as adjustment costs in labor demand bentolila and bertola 1990 hamermesh 1989 hopenhayn and rogerson 1993 nickell 1987 rendon 2004 this literature finds that the effects of eurosclerosis that is labor markets with high firing costs are ambiguous in good times sclerotic labor markets create fewer jobs than free labor markets however in bad times sclerotic labor markets reduce job destruction most of the research done in latin america has been done under these guidelines obtaining statistically significant negative effects of job security provisions on employment rates 1 furthermore using country level data for latin america and organization for economic cooperation and development countries heckman and pages serra 2000 found large effects of job security provisions on employment 2 which are robust to several specifications ols random and fixed effects the authors present their results as a strong evidence against freeman s 2000 view that job security regulations mostly affect distribution but not efficiency and advocate the substitution of job security provisions by other mechanisms that provide income security at lower efficiency and inequality costs under a classic labor demand framework and using worker and firm level data this article provides new evidence in the same direction extending the computation of the effects of job security provisions to deadweight losses hamermesh 1993 surveys several studies on the estimation of labor demand and remarks that estimates of the labor cost employment elasticity should be interpreted and compared cautiously depending on the specification adopted capital is an explanatory variable in a short run labor demand estimation it is not in a long run labor demand estimation similarly output is included in the estimation of a conditional labor demand but excluded in the estimation of an unconditional labor demand

employment changes the structure of adjustment costs and plant size abstract in this paper we analyze the pattern of employment adjustment using a rich panel of norwegian plants the data suggest that the frequency of episodes of zero net employment changes is inversely related to plant size we develop and estimate a simple q model of labor demand allowing for the presence of fixed linear and quadratic components of adjustment costs the econometric evidence supports the existence of purely fixed components unrelated to plant size as a result the range of inaction is wider for smaller plants the quadratic component of costs is also always important in most specifications fixed costs are higher for employment contractions the quadratic component is higher during employment contractions compared to expansions for small plants while this is not true for larger plants

effects of the minimum wage on employment dynamics the voluminous literature on minimum wages offers little consensus on the extent to which a wage floor impacts employment we argue that the minimum wage will impact employment over time through changes in growth rather than an immediate drop in relative employment levels we show that commonly used specifications in this literature especially those that include state specific time trends will not accurately capture these effects using three separate state panels of administrative employment data we find that the minimum wage reduces job growth over a period of several years this finding is supported using several empirical specifications

semiglobalization and international business strategy if markets were either completely isolated by or integrated across borders there would be little room for international business strategy to have content distinctive from mainstream strategy but a review of the economic evidence about the international integration of markets indicates that we fall in between these extremes into a state of incomplete cross border integration that i refer to as semiglobalization more specifically most measures of market integration have scaled new heights in the last few decades but still fall far short of economic theory s ideal of perfect integration the diagnosis of semiglobalization does more than just supply a relatively stable frame of reference for thinking about the environment of cross border operations it also calls attention to the critical role of location specificity in the prospects of distinctive content for international business strategy relative to mainstream business and corporate strategy in addition it flags factors products subject to location specificity as being salient from the perspective of international business finally it highlights the scope for strategies that strive to capitalize on the large residual barriers to cross border integration as well as those that simply try to cope with them

estimating preferences for local public services using migration data using swedish micro data the paper examines the impact of local public services on community choice the choice of community is modelled as a choice between a discrete set of alternatives it is found that given taxes high spending on child care attracts migrants less conclusive results are obtained with respect to the role of spending on education and elderly care high local taxes deter migrants relaxing the independence of the irrelevant alternatives assumption by estimating a mixed logit model has a significant impact on the results

seniority rules and productivity an empirical test the primary purpose of this paper is to test empirically the effect of labor quality on short run manufacturing productivity in doing so the study makes major advances in two areas for the first time a job tenure function is estimated and a time series of job tenure in manufacturing is developed this estimated tenure series empirically verifies the use of seniority rules in the firm worker employment relationship having generated a tenure series the authors then test whether tenure enhances productivity in manufacturing the results clearly indicate that seniority rules have a statistically significant positive impact on productivity and the pattern of the seniority rules is reminiscent of a model where human capital has a specific component copyright 1989 by the london school of economics and political science

a comment on the economics of labor adjustment mind the gap rejoinder numerous papers in this literature have used these questions as motivation understanding the structure of labor adjustment costs is relevant any time a policy or forecasting question requires input on the properties of labor dynamics of course for some policy questions we are interested in the aggregate effects of policies hence understanding whether nonconvexities have implications for aggregate labor demand is crucial as well in terms of the ongoing discussion over these questions there seems to be agreement that the simple quadratic adjustment cost model is not an adequate representation of the costs plants face in adjusting the number of workers from data displayed by daniel hamermesh 1989 and caballero et al 1997 hereafter ceh one is certainly struck by both the inactivity of labor adjustment and the bursts of job creation and destruction at the plant level that said while these observations serve as evidence against a model which contains only quadratic adjustment costs they do not directly identify a particular structure of adjustment costs at the plant level inspection of the adjustment patterns reported in ceh though cast in terms of gaps does provide some evidence of partial adjustment and thus suggests the presence of both convex and nonconvex adjustment costs further caballero and engel 1993 hereafter ce and ceh appear to have provided useful evidence on the second question the nonlinearities they uncover in aggregated data suggest that nonconvexities at the plant level have aggregate implications

the employment financing nexus evidence from a panel of west german firms the objective of the paper is to investigate the linkage between financial factors and employment decisions of west german firms the underlying model is based upon rational expectations and convex adjustment costs the time series cross section estimates for the period 1989 1994 are obtained using information on individual firms contained in business surveys we find that financial constraints can indeed restrain the level of employment in small firms on the contrary there is no evidence that this result applies to larger firms as well

inventories and the automobile market this article studies the within model year pricing production and inventory management of new automobiles using new monthly data on u s transaction prices we document that for the typical vehicle prices fall over the model year at a 9 0 annual rate concurrently both sales and inventories are hump shaped to explain these time series we formulate an industry model for new automobiles in which inventory and pricing decisions are made simultaneously the model predicts that automakers build to stock inventory management policy substantially influences the time series of prices and sales accounting for four tenths of the price decline observed over the model year

fixed term contracts and the dynamics of labour demand abstract we estimate a model of labour demand that accounts for dynamics arising from the relative costs of hiring and firing workers on either indefinite term contract itc or fixed term contract ftc we use a panel of 1000 french firms for which we can measure the number of entries and exits for each type of contract between 1988 and 1992 our estimates suggest that 1 it is much more costly to lay off workers under itc than to hire them 2 it is much less costly to adjust the number of ftc than to adjust the number of itc 3 the asymmetry between hiring and layoff costs is more important for non production than for production workers

lost in transition the costs and consequences of sectoral labour adjustment this paper uses an equilibrium search and matching model to study canada s sectoral labour adjustment in 2002 2006 during an increase in global commodity prices and exchange rate appreciation i estimate economically significant adjustment costs for the aggregate economy in this episode and demonstrate that difficulty in transferring skills between jobs for individual workers can be an important contributor to these aggregate costs the analysis also demonstrates that the level of unemployment benefits impacts the economy s sectoral composition its aggregate productivity and the speed of its adjustment to shocks ce texte utilise un modele d equilibre de la recherche et de l arrimage pour etudier les ajustements sectoriels du travail au canada dans la periode 2002 2006 une periode d appreciation des prix globaux des produits de base et du taux de change j estime que les couts d ajustement sont economiquement significatifs pour l economie agregee au cours de cet episode et que la difficultea transferer les competences entre emplois pour les travailleurs individuels peut etre une source importante de ces couts agreges les analyses montrent aussi que le niveau des prestations d assurance emploi a un impact sur la composition sectorielle de l economie sur la productivite et sur la vitesse des ajustements aux chocs

labor demand and the structure of adjustment costs this study examines the costs firms face in adjusting labor demand to exogenous shocks evidence on monthly plant level data shows that adjustment proceeds in jumps employment is unchanged in response to small shocks but moves instantaneously to a new equilibrium if the shocks are large results in the large literature that assumes smooth adjustment are due to aggregation of this nonlinear relation the finding has implications for cyclical changes in productivity for severance pay layoff and plant closing restrictions and for all other policies that affect the cost of adjusting employment copyright 1989 by american economic association

what makes cities attractive the determinants of urban labour migration in germany striking disparities characterise the population growth of cities in industrialised countries some cities suffer from ongoing population decline whereas other cities have experienced increasing numbers of inhabitants in recent years whether labour market conditions or amenities via their impact on migration primarily account for differences in cities demographic development is an important issue this paper investigates the determinants of the migration balance of german cities between 2000 and 2007 the focus is on the mobility of workers because labour migration in particular affects the future prospects of cities the findings suggest that not only labour market conditions but also amenities have an impact on the net migration rate moreover large cities seem to be ceteris paribus more attractive than small cities this finding possibly points to the importance of amenities such as cultural infrastructure and matching externalities in urban labour markets that are linked to city size urban policy aimed at enhancing the attractiveness of cities should thus consider both boosting the local economy and improving the quality of life

cash holdings and labor heterogeneity the role of skilled labor firms differ in their dependence on skilled labor and face labor adjustment costs that increase with their workers skill level we show that firms with a higher share of skilled workers and thus less flexibility to adjust their labor demand in response to cash flow shocks hold more precautionary cash the effect of labor skills on cash holdings is more pronounced for financially constrained firms and varies with exogenous differences in firing and hiring costs we address endogeneity concerns by using subsamples of firms with reasonably similar characteristics propensity score matching and a quasi experimental shock to labor markets

sequentiality versus simultaneity interrelated factor demand abstract firms may adjust capital and labor sequentially or simultaneously in this paper we develop a structural model of interrelated factor demand subject to nonconvex adjustment costs and estimated by simulated method of moments based on norwegian manufacturing industry plant level data parameter estimates reveal cost advantages for adjusting capital and making net changes in labor simultaneously factor demand models with fully specified interrelated adjustment costs structures perform best to describe the dynamic panel data

the evolution of research on coordination mechanisms in multinational corporations the mechanisms of coordination used by multinational corporations mncs are studied through an exhaustive literature review a pattern of evolution is found as time has passed researchers have concentrated more on subtler and informal mechanisms abandoning their unidimensional focus on structural issues it is suggested that the increase in the study of those mechanisms may be due among other reasons to the fact that mncs are indeed making more use of them that could be explained by changes in the international competitive environment which force firms to adjust their strategies requiring ever more multidimensional coordination

experiential knowledge and costs in the internationalization process using a behavioral approach this study identifies and delineates components of experiential knowledge in the internationalization process three hypotheses are developed and tested they center around the lack of knowledge in the areas of foreign business foreign institutions and firm internationalization as well as the effect that this lack of knowledge has on managers perceived cost in the internationalization process with the help of a lisrel based structural model the three hypotheses are tested on a sample of 362 service firms the analysis shows that lack of internationalization knowledge has a strong impact on the lack of both business and institutionalization but there is no direct effect of lack of internationalization knowledge on perceived cost of internationalization

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

what are the determinants of hiring the importance of product market demand and search frictions in this article we study the importance of product market demand and search frictions for hiring we use a search matching model with imperfect competition in the product market to derive an equat

non convex costs and capital utilization a study of production scheduling at automobile assembly plants i study detailed data from eleven automobile assembly plants these data display considerable cross plant heterogeneity in production scheduling to explain the observed heterogeneity i solve a dynamic programming model when desired production is below the plant s minimum e cient scale non convexities induce production bunching the plant uses less than full capital utilization on average and production is more volatile than sales when desired production is above the plant s minimum e cient scale the plant operates in a convex region of the cost curve in this case it uses high levels of capital utilization and production is less volatile than sales 2000 elsevier science b v all rights reserved jel classixcation e23 d21 l23

the uppsala internationalization process model revisited from liability of foreignness to liability of outsidership the uppsala internationalization process model is revisited in the light of changes in business practices and theoretical advances that have been made since 1977 now the business environment is viewed as a web of relationships a network rather than as a neoclassical market with many independent suppliers and customers outsidership in relation to the relevant network more than psychic distance is the root of uncertainty the change mechanisms in the revised model are essentially the same as those in the original version although we add trust building and knowledge creation the latter to recognize the fact that new knowledge is developed in relationships

the response of prices sales and output to temporary changes in demand we determine empirically how the big three automakers accommodate shocks to demand they have the capability to change prices alter labor inputs through temporary layoffs and overtime or adjust inventories these adjustments are interrelated non convex and dynamic in nature combining weekly plant level data on production schedules and output with monthly data on sales and transaction prices we estimate a dynamic profit maximization model of the firm using impulse response functions we demonstrate that when an automaker is hit with a demand shock sales respond immediately prices respond gradually and production responds only after a delay the size of the immediate sales response is linear in the size of the shock but the delayed production response is non convex in the size of the shock for sufficiently large shocks the cumulative production response over the product cycle is an order of magnitude larger than the cumulative price response we examine two recent demand shocks the ford explorer firestone tire recall of 2000 and the september 11 2001 terrorist attacks
