high risk low return and vice versa the effect of product innovation on firm performance in a transition economy common wisdom suggests that high risk strategies will be associated with high expected returns and vice versa focusing on the effect of new product development on firm performance in this paper

stylized facts and stylized illusions inflation and productivity revisited recent estimates of a negative empirical relationship between inflation and the rate of growth of productivity provide a strong case for vigorous anti inflationary policy this paper tests the robustness of this evidence using long quarterly and annual datasets for four countries canada united states united kingdom west germany our results from cointegration and other time series tests show no evidence for any connection between inflation and the level of productivity we do find a strong connection between inflation and productivity growth but it is so internally inconsistent as to be incredible the best explanation is that it is accounted for entirely by statistical bias from attempting to cointegrate stationary and non stationary variables

estimating dynamic games of oligopolistic competition an experimental investigation we evaluate standard assumptions in the estimation of dynamic oligopoly models with laboratory data using an entry exit game we estimate structural parameters under the assumption that the data are generated by a markov perfect equilibrium and subsequently predict counterfactual behavior if behavior was collusive however the assumption would be violated and one would mispredict counterfactuals the laboratory allows us to compare predicted behavior to true counterfactuals implemented as treatments our main finding is that prediction errors due to collusion are modest in size we also document a different deviation from equilibrium behavior inertia that can lead to large prediction errors

productivity growth scale economies and the schumpeterian hypothesis the schumpeterian hypothesis is usually interpreted as implying 1 a positive relationship between innovation and monopoly power with the concomitant above normal profits or 2 large firms are more than proportionately more innovative than small firms 6 22 empirical tests of the latter version of the schumpeterian hypothesis have traditionally examined the relationship between some measure of innovative activity and firm size innovative activity has been measured using innovative inputs such as r d expenditures or the employment of scientific and engineering personnel or innovative outputs as represented by the number of patents significant innovations or sales of new products the shortcomings of each of these as a proxy for innovative activity has been discussed extensively in the literature studies by phillips 10 stigler 13 carter and williams 3 weiss 15 allen 1 bock and farkas 2 greer and rhoades 4 kendrick and grossman 7 sveikauskas and sveikauskas 14 and scherer 11 have employed the growth rate of productivity either labor or total factor as a measure of innovative activity in empirical tests of the schumpeterian hypothesis this variable serves as a proxy for the rate of technical change and is particularly appropriate as a measure of dynamic efficiency in industries such as transportation primary metals utility services etc where the emphasis is on process and not product innovations as noted by kamien and schwartz 6 productivity may grow over time as a result of i shifts in the production function associated with technical change or ii increases in productivity arising from economies of scale this study demonstrates that inclusion of the scale effect in estimates of productivity growth imparts a downward bias in the relationship between firm size and dynamic efficiency which may lead to an inappropriate rejection of the schumpeterian hypothesis the empirical implications of this bias are illustrated using data from a sample of electric utilities operating in the u s during the period 1961 73

attitudes toward risk and the risk return paradox prospect theory explanations this study attempted to explain bowman s risk return paradox in terms of recent research in behavioral decision theory and prospect theory the research emphasized the role of reference or target

business risk and return a test of simultaneous relationships bowman 1980 found an unexpected and paradoxical negative relationship between risk and return in many firms and for about a decade various researchers have attempted to explain the paradox this article summarizes some of those explanations and shows that industry conditions and business strategies are likely to influence both risk and return the relationships are depicted in a simultaneous model where business return risk and debt are endogenously determined the model is tested with 132 nondiversified firms in 8 disparate industries ols estimates of the parameters of the model show the risk return relationship to be significantly negative as many past researchers have found however 3sls estimates of the parameters of the simultaneous model reveal no significant relationship between risk and return the tentative conclusion is that many of the studies in the line of research concerned with bowman s 1980 paradox may have used an improperly specified model and that when a more realistic sim

trucks without bailouts equilibrium product characteristics for commercial vehicles the entry and exit of products rather than firms serve as the main equilibrating force in many markets so accurately predicting changes from a merger or bankruptcy should incorporate this behavior this paper estimates a structural model of the us commercial vehicle market and demonstrates the importance of allowing for endogenous product offerings in the context of the 85 billion automotive industry bailout in 2009 under alternate policies that facilitate an acquisition or liquidation of gm and chrysler product entry and exit moderate markup increases and output decreases by up to three quarters

semiparametric inference in dynamic binary choice models we introduce an approach for semiparametric inference in dynamic binary choice models that does not impose distributional assumptions on the state variables unobserved by the econometrician the proposed framework combines bayesian inference with partial identification results the method is applicable to models with finite space of observed states we demonstrate the method on rust s model of bus engine replacement the estimation experiments show that the parametric assumptions about the distribution of the unobserved states can have a considerable effect on the estimates of per period payoffs at the same time the effect of these assumptions on counterfactual conditional choice probabilities can be small for most of the observed states

economic growth and development towards a catchup model we develop a model for economic growth applicable to a group of countries constituting around half of the gross global production that have been consistently catching up to the us since 1960 or so this group can be termed the convergence club the model has a theoretical basis developed in other publications cited but the present work is essentially empirical it demonstrates that there is a very strong correlation between catchup growth with respect to the us and an energy proxy ep the energy proxy that works best is a linear combination of domestic electric power consumption petroleum oil consumption per capita compared to the us levels the results presented here do not constitute a theory of growth but they are consistent with theory presented elsewhere on a practical level we argue that consistent catchup trends over the past 40 years can safely be extrapolated for a few more decades for scenario construction purposes we also believe that the observed catchup trends can be regarded as potential mid term or long term growth trajectories for transition economies and others that have recently been adversely affected by conflict or mismanagement

a behavioral theory of r d expenditures and innovations evidence from shipbuilding i base an integrated model of innovation development and launch on the behavioral theory of the firm this model specifies that research and development expenses are increased when low performance causes problemistic search and when excess resources cause slack search innovations generated by search are launched if low performance gives managers high risk tolerance using data from shipbuilding firms i show that high performance reduces r d intensity and innovation launches and high slack increases r d intensity as predicted

empirical implications of alternative models of firm dynamics abstract this paper considers two models of firm behavior that allow for heterogeneity among firms idiosyncratic or firm specific sources of uncertainty and discrete outcomes exit and or entry both the characteristics of firm level panel data sets and the nature of the questions we characteristically ask of them imply that models with these features are likely to underlie most detailed empirical work on microdata sets the models we consider are a bayesian learning model due to jovanovic 20 and a model of research and exploration due to ericson and pakes 11 the paper provides a simple set of empirical procedures to help determine which if either of these two models might be appropriate for alternative data sets we conclude by checking for the implications of the two models on an eight year panel of wisconsin firms the results indicate that one model is consistent with the data on manufacturing firms while the other is consistent with the data on retail trade journal of economic literature classification numbers c52 l60 l80

menu costs and dynamic duopoly examining a state dependent pricing model in the presence of menu costs and dynamic duopolistic interactions this paper claims that the assumption regarding market structure is crucial for identifying the menu costs for price changes prices in a dynamic duopolistic market can be more rigid than those in more competitive markets such as a monopolistic competition market therefore the estimates of menu costs under monopolistic competition are potentially biased upward due to the price rigidity from strategic interactions between dynamic duopolistic firms by developing and estimating a dynamic discrete choice model with duopoly to correct for this potential bias this paper provides empirical evidence that dynamic strategic interactions as well as menu costs play an important role in explaining the observed degree of price rigidity in weekly retail prices

measuring productivity in economic growth since world war ii the improvement in the material well being of their citizens has been an explicit goal of nearly every nation associated with this goal is the challenge of how to utilize primary resources more efficiently to get more from what goes into the productive process success in this endeavor requires that the economic processes be in continual disequilibrium which gives rise to opportunities that decision makers can use to advan

prospect theory and the risk return relation some belgian evidence in this study fiegenbaum and thomas s application of prospect theory to empirically derived risk return relations was replicated and extended with belgian accounting data four profitability varia

prices and endogenous market structure in office supply superstores we consider the relationship between prices and market structure for office supply superstores in the u s which was central to the federal trade commission s opposition to the merger of staples and office depot due to potential biases in a standard regression we employ a two stage approach in which a model of endogenous market structure provides correction terms for a second stage price regression using a cross section of data on market structures and staples prices we find that excluding the correction term substantially distorts the importance of competitors as the two stage model yields stronger negative relationships between prices and market structure variables

the impact of electric power on productivity according to the historical record the increased use of energy in general and electric power in particular stands as one of the key factors in productivity growth growth accountants however find little support for this view rejecting claims that the productivity slowdown can be attributed to the lower rate of growth of the energy input in us manufacturing in this study an attempt at reconciling the historical record with the empirical facts is made specifically the commonly used factor income shares in the relevant divisia input growth index are replaced by the estimated output input elasticities the latter attribute a considerably larger role to electric power than previous studies indicated these are then used to reevaluate the sources of growth in us manufacturing

estimating the innovator s dilemma structural analysis of creative destruction in the hard disk drive industry 1981 1998 this paper studies strategic industry dynamics of creative destruction in which firms and technologies experience turnover theories predict that cannibalization between existing and new products delays incumbents innovation whereas preemptive motives accelerate it incumbents cost dis advantage relative to that of entrants would further reinforce these tendencies to empirically assess these three forces i estimate a dynamic oligopoly model using a unique panel data set of hard disk drive manufacturers the results suggest that despite strong preemptive motives and a substantial cost advantage over entrants cannibalization makes incumbents reluctant to innovate which can explain at least 57 percent of the incumbent entrant innovation gap

china s transition and its implications for international business this paper focuses on institutional change as the central and most consequential contextual aspect of china s transition identification of key characteristics of china s emergent institutions leads to propositions on their relevance for international business practice china s transition also raises issues for theory development including the way that transition is modeled the need to draw upon multiple perspectives and the concomitants of a contextual approach

computable markov perfect industry dynamics we provide a general model of dynamic competition in an oligopolistic industry with investment entry andexit toensurethatthereexistsacomputationallytractablemarkov perfectequilibrium we introduce firm heterogeneity in the form of randomly drawn privately known scrap values and setup costs into the model our game of incomplete information always has an equilibrium in cutoff entry exit strategies in contrast the existence of an equilibrium in the ericson and pakes model of industry dynamics requires admissibility of mixed entry exit strategies contrary to the assertion in their article that existing algorithms cannot cope with in addition we provide a condition on the model s primitives that ensures that the equilibrium is in pure investment strategies building on this basic existence result we first show that a symmetric equilibrium exists under appropriate assumptions on the model s primitives second we show that as the distribution of the random scrap values setup costs becomes degenerate equilibria in cutoff entry exit strategies converge to equilibria in mixed entry exit strategies of the game of complete information

prospect theory and the risk return association an empirical examination in 85 industries a new sample of 85 industries about 3 300 firms defined in terms of homogenous products provides strong evidence that prospect theory can explain the tradeoff between two of the most researched parameters in evaluating organizations namely risk and return in particular organizations below their target level are found to be risk takers hl while organizations above their target level are risk averters h2 moreover the below target tradeofl was generally steeper than the above target with a median below to above slope ratio of about 3 l h3 risk and return are probably the two single parameters most researched by the various and related disciplines of economics finance and management although each one of them has looked at these two parameters from different aspects and for different purposes they have provided a wide understanding of these two factors in the contest of the theory of the firm the purpose of this study is to look closely at the relationship between these two important parameters in order to understand firm s competitive behavior using the recent development in behavioral decision theory namely prospect theory kahneman and tversky 1979 although march 1988 has criticized the discipline of management for its later adaptation in considering risk elements for evaluating organization performance and decision making processes recent studies e g bettis 1981 rumelt 1974 singh 1986 jemison 1987 and baird and thomas 1986 have paid considerable attention to risk aspects in evaluating the performance of firms in general these studies have concluded that the characteristics of the firms environment strategy and implementation processes have significant and important influence on the firm s risk level and its associated rate of return bowman 1980 has looked closely at 85 u s industries and explored the

dynamic branching and interest rate competition of commercial banks evidence from hungary abstract i supplement previous models of bank competition by incorporating the endogenous branching choices of commercial banks i apply a dynamic structural model of banks branching and interest rate choices to a unique bank level dataset on hungarian commercial banks during 2004 2007 i find that banks charge a premium in interest rates for relative branch network dominance and banks with relatively smaller networks are less likely to close branches i present significant and robust estimates of branch setup costs and scrap values and discuss the potential use of branching restrictions as regulatory tools to alter lending rates and consumer surplus

the incidence of classified property taxes in a three sector model with an imperfectly mobile population abstract this paper analyzes the incidence of a classified property tax imposing different effective tax rates on residential commercial and industrial property as compared to a uniform property tax taxing capital and land in all sectors at the same rate our model includes three sectors commercial industrial and residential and three factors of production land labor and capital capital is assumed to be perfectly mobile but we consider varying degrees of labor mobility allowing the possibility that part of a classified property tax may be shifted to workers through lower wages

price leadership and welfare losses in u s manufacturing reply a model of price leadership is used to estimate the welfare losses dueto monopoly in u s manufacturing given that the leaders behave independently an hypothesis confirmed empirically the deadweight lossis estimated at 0 114 percent of gnp based on a sample of 445 four digit industries this estimate lends strong support to arnold c harberger s finding of thirty years ago copyright 1986 by american economic association

toward a model of risk in declining organizations an empirical examination of risk performance and decline scholars who study organizational decline have argued that declining organizations reduce or eliminate their riskier activities such as innovation further they cite reduced risk taking as a primary contributor to further decline scholars with an interest in risk per se come to the opposite conclusion low performing firms often take more risks than other firms and such risks reduce subsequent performance this study attempts to resolve these conflicting views by examining the risk of firms in decline our model based on cyert march s cyert r m j g march 1963 a behavioral theory of the firm prentice hall englewood cliffs nj behavioral theory of the firm includes six basic variables 1 performance 2 slack 3 aspirations 4 expectations 5 risk income stream uncertainty and 6 organization size as a measure of decline the estimated model includes prior levels of risk and performance in the risk and performance equations respectively as controls this study uses data on 34

price leadership and dynamic aspects of oligopoly in u s manufacturing this study which covers a sample of 314 four digit industries taken from an exhaustive set of 450 four digit industries shows that increases in concentration associated with rising productivity occur mainly in low concentration industries while decreases in concentration associated with rising productivity occur mainly in high concentration industries the empirical results of this study indirectly lend support to a plausible hypothesis that a small group of firms makes a big impact on the productivity of an initially unconcentrated industry and thereby concentrates it later the small firms imitate the now big firms and concentration goes down while productivity keeps rising

customer satisfaction productivity and profitability differences between goods and services there is widespread belief that firms should pursue superiority in both customer satisfaction and productivity however there is reason to believe these two goals are not always compatible if a firm improves productivity by downsizing it may achieve an increase in productivity in the short term but future profitability may be threatened if customer satisfaction is highly dependent on the efforts of personnel if so there are potential tradeoffs between customer satisfaction and productivity for industries as diverse as airlines banking education hotels and restaurants managers in these types of service industries as well as goods industries in which the service component is increasing need to understand whether or not this is the case for example if efforts to improve productivity can actually harm customer satisfaction and vice versa the downsizing of u s and european companies should be viewed with concern it follows that developing a better understanding of how customer satisfaction and productivity relate to one another is of substantial and growing importance especially in light of expected continued growth in services throughout the world economy the objective of this paper is to investigate whether there are conditions under which there are tradeoffs between customer satisfaction and productivity a review of the literature reveals two conflicting viewpoints one school of thought argues that customer satisfaction and productivity are compatible as improvements in customer satisfaction can decrease the time andeffort devoted to handling returns rework warranties and complaint management while at the same time lowering the cost of making future transactions the second argues that increasing customer satisfaction should increase costs as doing so often requires efforts to improve product attributes or overall product design a conceptual framework useful in resolving these contradictory viewpoints is developed the framework serves in turn as a basis for developing a theoretical model relating customer satisfaction and productivity the model predicts that customer satisfaction and productivity are less likely to be compatible when 1 customer satisfaction is relatively more dependent on customization the degree to which the firm s offering is customized to meet heterogeneous customers needs as opposed to standardization the degree to which the firm s offering is reliable standardized and free from deficiencies and 2 when it is difficult costly to provide high levels of both customization and standardization simultaneously to move forward from the model s propositions to the development of testable hypotheses we argue that services are more likely than goods to have the preceding characteristics hence tradeoffs between customer satisfaction and productivity should be more prevalent for services than for goods although this classification is not precise many services are standardizable and many goods have a service component it has the advantage of allowing an initial test of the propositions the empirical work employs a database matching customer based measures of firm performance with traditional measures of business performance such as productivity and return on investment roi the central feature of this database is the set of customer satisfaction indices provided by the swedish customer satisfaction barometer scsb the scsb provides a uniform set of comparable customer based firm performance measures and offers a unique opportunity to test the study s hypotheses the findings indicate that the association between changes in customer satisfaction and changes in productivity is positive for goods but negative for services in addition while both customer satisfaction and productivity are positively associated with roi for goods and services the interaction between the two is positive for goods but significantly less so for services taken together the findings suggest support for the contention that tradeoffs are more likely for services hence simultaneous attempts to increase both customer satisfaction and productivity are likely to be more challenging in such industries of course this does not imply that such firms should not seek improvements in both productivity and customer satisfaction for example appropriate applications of information technology may improve both customer satisfaction and productivity simultaneously the findings should provide motivation for future research concerning the nature of customer satisfaction and productivity as well as appropriate strategy and tactics for each one it is worth emphasizing that this is an issue that is not only important today but certainly will become even more important in the future as the growth of services continues and world markets become increasingly competitive the importance of customer satisfaction will also increase to compete in such a world firms must strike the right balance between their efforts to compete efficiently and their efforts to compete effectively

the effect of uncertainty on investment evidence from texas oil drilling this paper estimates the response of investment to changes in uncertainty using data on oil drilling in texas and the expected volatility of the future price of oil using a dynamic model of firms investment problem i find that i the response of drilling activity to changes in price volatility has a magnitude consistent with the optimal response prescribed by theory ii the cost of failing to respond to volatility shocks is economically significant and iii implied volatility data derived from futures options prices yields a better fit to firms investment behavior than backward looking volatility measures such as garch jel c58 d92 g13 g31 l71 q31 the real options literature beginning with marschak 1949 and arrow 1968 and developed in bernanke 1983 pindyck 1991 and dixit and pindyck 1994 explains how firms should make decisions about investments that involve sunk costs real options theory views such investments as options in that at any point in time a firm may choose to either invest immediately or delay and observe the evolution of the investment s payoff a key insight is that the option to delay has value when future states of the world with positive returns to investing and states with negative returns are both possible even holding the expected future return constant at its present level thus in the presence of irreversibility and uncertainty a naive investment timing rule proceed with an investment if its expected benefit even slightly exceeds its cost is suboptimal because it does not account for the value of continuing to hold the option instead firms should delay irreversible investments until a significant gap develops between the investments expected benefits and costs moreover as uncertainty increases real options theory tells us that the incentive to delay should grow stronger and the gap between the expected benefit and cost necessary to trigger investment should widen while real options theory therefore prescribes how firms should carry out irreversible investments in uncertain environments it is not empirically well known

productivity in the united states trends and cycles productivity growth in the us has taken a sharp downturn in recent years two experts provide a new body of comparative data on productivity since 1948 by major sector and industry the book analyzes 20 industries to highlight trends and fluctuations in productivity and to provide a better context for the discussion of policy options the authors set forth the causes of productivity advances based on growth accounting for the business economy as a whole they detail interindustry regressions with particular reference to the productivity slowdown since 1966 they look at both the traditional measure of productivity labor output per hour and the more recently developed measure of total factor productivity which takes into account capital as well as labor inputs the quarterly and annual data are used to relate changes to other basic variables such as factor prices unit costs and product prices an appendix presents data for 35 industries 42 references 8 figures 30 tables

productivity and the embodiment of technical progress this survey of the issues involved in the embodiment hypothesis that technical change and productivity can be explained by changes in the quality of inputs into the production process treats the interrelationships of technical change and productivity presents some empirical findings on this subject and discusses some fundamental issues in further studies of embodiment topics covered include the nature of the embodiment hypothesis the vintage model of capital and embodiment in other inputs the use of the embodiment hypothesis to study productivity trends the embodiment hypothesis and the productivity slowdown in the 1970s and 1980s and potential future applications of the embodiment hypothesis

a framework for dynamic oligopoly in concentrated industries in this article we introduce a new computationally tractable framework for ericson and pakes style dynamic oligopoly models that overcomes the computational complexity involved in computing markov perfect equilibrium mpe first we define a new equilibrium concept that we call moment based markov equilibrium mme in which firms keep track of their own state the detailed state of dominant firms and few moments of the distribution of fringe firms states second we provide guidelines to use mme in applied work and illustrate with an application how it can endogenize the market structure in a dynamic industry model even with hundreds of firms third we develop a series of results that provide support for using mme as an approximation we present numerical experiments showing that mme approximates mpe for important classes of models then we introduce novel unilateral deviation error bounds that can be used to test the accuracy of mme as an approximation in large scale settings overall our new framework opens the door to study new issues in industry dynamics

activist fiscal policy during and after the great recession that began in december 2007 the u s federal government enacted several rounds of activist fiscal policy in this paper we review the recent evolution of thinking and evidence regarding the effectiveness of activist fiscal policy although fiscal interventions aimed at stimulating and stabilizing the economy have returned to common use their efficacy remains controversial we review the debate about the traditional types of fiscal policy interventions such as broad based tax cuts and spending increases as well as more targeted policies while there have been improvements in estimates of the effects of broad based policies much of what has been learned recently concerns how such multipliers might vary with respect to economic conditions such as the credit market disruptions and very low interest rates that were central features of the great recession the eclectic and innovative interventions by the federal reserve and other central banks during this period highlight the imprecise divisions between monetary and fiscal policy and the many channels through which fiscal policies can be implemented

demand fluctuations in the ready mix concrete industry i investigate the role of demand shocks in the ready mix concrete industry using census data on more than 15 000 plants i estimate a model of investment and entry in oligopolistic markets these estimates are used to simulate the effect of eliminating short term local demand changes a policy of smoothing the volatility of demand has a market expansion effect the model predicts a 39 increase in the number of plants in the industry since bigger markets have both more plants and larger plants a demand smoothing fiscal policy would increase the share of large plants by 20 finally the policy of smoothing demand reduces entry and exit by 25 but has no effect on the rate at which firms change their size

real wage growth technical change and competition in the labor market the paper measures the rate of growth of average labor cost and the real wage for the twenty u s two digit manufacturing industries 1948 76 it is argued that these rates of growth give interesting information which other studies on the real wage ignore the results suggest that the gains from technical advance are shared equally across all labor markets consistent with the competitive paradigm a simple and appealing rationale for the observation that high growth industries show the slowest relative rate of growth of prices is also given t he general theory keynes 1936 unleashed many controversies one of the earliest and still topical controversy is the cyclical behavior of the real wage essentially the real wage employment debate has focussed on whether or not the demand schedule slopes downwards and there have been many studies on this topic producing a variety of conflicting findings a common feature of the real wage employment studies is to abstract away from the growth in the real wage that is bound to occur in a growing economy these studies are primarily concerned with deviations from trend or innovations in the real wage and the theme of this paper is that to ignore the growth in the real wage is to throw away valuable and interesting information this information on real wage growth tells us a great deal about competition in the labor market this study should be seen as being complementary rather than conflicting with the real wage employment studies the existence of a downward sloping demand curve for labor is after all not sufficient and probably not necessary for the functioning of competitive labor markets over the span of years 1948 76 i find that individual u s manufacturing industries record widely varying rates of productivity growth however these same industries tend to show a common rate of growth of the real wage this feature of productivity growth was emphasized by the late salter 1960 in his pathbreaking analysis of technical change he writes there is no tendency for above average increases in labour productivity to be accompanied by above average increases in earnings

welfare implications of oligopoly in u s food manufacturing a statistical procedure is used to show that increased concentration in u s food manufacturing industries is associated with increased total input productivity a price leadership model is employed in order to estimate total welfare loss if an elasticity of 1 is assumed deadweight loss to society is estimated at 0 5 of food value if an elasticity of 0 5 is assumed total loss to consumers amounts to 6 11 of food value which is 10 billion in 1975 the increase in total factor productivity which is linked to concentration is roughly sufficient to offset the entire loss to consumers

learning by doing organizational forgetting and industry dynamics learning by doing and organizational forgetting have been shown to be important in a variety of industrial settings this paper provides a general model of dynamic competition that accounts for these economic fundamentals and shows how they shape industry structure and dynamics previously obtained results regarding the dominance properties of flrms pricing behavior no longer hold in this more general setting we show that forgetting does not simply negate learning rather learning and forgetting are distinct economic forces in particular a model with learning and forgetting can give rise to aggressive pricing behavior market dominance and multiple equilibria whereas a model with learning alone cannot

decomposing growth in revenues and costs into price quantity and total factor productivity contributions this article employs the superlative fisher and tornqvist indexes for exact decomposition of growth in nominal revenues and costs the findings confirm the well known result that these indexes very closely approximate each other implying that the mathematically simpler and computationally easier tornqvist is the more practicable index moreover this article s nominal growth decomposition yields all the results from the more common real growth decomposition and is also more informative for policy purposes application to the us agricultural sector during 1948 2001 shows that of the 3 31 average annual growth in revenues tfp growth contributed 1 90 percentage points pct pts growth in output prices added 1 43 pct pts while growth in input quantities contributed 0 02 pct pts i e fewer inputs therefore real output growth or revenue growth less output price growth was 1 88 pct pts revealing that tfp s 1 90 pct pts growth contribution was fully responsible for real output growth with

patents and the global diffusion of new drugs analysis of the timing of launches of 642 new drugs in 76 countries during 1983 2002 shows that patent and price regulation regimes strongly affect how quickly new drugs become commercially available in different countries price regulation delays launch while longer and more extensive patent rights accelerate it health policy institutions and economic and demographic factors that make markets more profitable also speed up diffusion the estimated effects are generally robust to controlling for endogeneity of policy regimes with country fixed effects and instrumental variables the results highlight the important role of policy choices in driving the diffusion of new innovations

declining productivity revisited secular trends or cyclical losses dickens 1982 argued that the productivity slowdown since the mid 1960s is cyclical and not a long term trend this letter tests the robustness of dickens conclusion specifically with respect to labor productivity

inferring labor income risk and partial insurance from economic choices this paper uses the information contained in the joint dynamics of individuals labor earnings and consumption choice decisions to quantify both the amount of income risk that individuals face and the extent to which they have access to informal insurance against this risk we accomplish this task by using indirect inference to estimate a structural consumption savings model in which individuals both learn about the nature of their income process and partly insure shocks via informal mechanisms in this framework we estimate i the degree of partial insurance ii the extent of systematic differences in income growth rates iii the precision with which individuals know their own income growth rates when they begin their working lives iv the persistence of typical labor income shocks v the tightness of borrowing constraints and vi the amount of measurement error in the data in implementing indirect inference we find that an auxiliary model that approximates the true structural equations of the model which are not estimable works very well with negligible small sample bias the main substantive findings are that income shocks are moderately persistent systematic differences in income growth rates are large individuals have substantial amounts of information about their income growth rates and about one half of income shocks are smoothed via partial insurance putting these findings together the amount of uninsurable lifetime income risk that individuals perceive is substantially smaller than what is typically assumed in calibrated macroeconomic models with incomplete markets

frictions in a competitive regulated market evidence from taxis this paper presents a dynamic equilibrium model of a taxi market the model is estimated using data from new york city yellow cabs two salient features by which most taxi markets deviate from the efficient market ideal are first matching frictions created by the need for both market sides to physically search for trading partners and second regulatory limitations to entry to assess the importance of these features we use the model to simulate the effect of changes in entry alternative matching technologies and different market density we use the geographical features of the matching process to back out unobserved demand through a matching simulation the matching function exhibits increasing returns to scale which is important to understand the impact of changes in this market and has welfare implications for instance although alternative dispatch platforms can be more efficient than street hailing platform competition is harmful because it reduces effective density

estimation of dynamic discrete choice models in continuous time with an application to retail competition this paper provides a method for estimating and solving dynamic discrete choice models in a continuous time framework that is computationally light the method is particularly useful in dynamic games in the proposed framework players face a standard dynamic discrete choice problem at decision times that occur stochastically the resulting stochastic sequential structure naturally admits the use of ccp methods for estimation and makes it possible to compute counterfactual simulations for relatively high dimensional games we apply our techniques to examine the impact of walmart s entry into the retail grocery industry showing that even the threat of entry by walmart has a substantial eect on market structure

estimating a war of attrition the case of the us movie theater industry this paper estimates the impact of competition and exogenous demand decline on the exit process of movie theaters in the us from 1950 1965 i modify fudenberg and tirole 1986 s model of exit in a duopoly with incomplete information to an oligopoly i estimate this model with panel data using variations in tv diusion across house holds and other market characteristics to identify the parameters in the theater s payo function and the distribution of unobservable exit values using the estimated model i show that theaters who are making negative pro ts may choose to remain in the market if they expect to outlast their competitors because at that point their pro ts would increase this creates a signi cant delay in the exit process in addition by decompos ing the across market variation in the exit process i nd that tv diusion explains a substantial proportion of the variation in the exit process

information technology and the world economy this paper addresses the impact of investment in information technology it on the recent resurgence of world economic growth we describe the growth of the world economy seven regions and 14 major economies during the period 1989 2003 we allocate the growth of world output between input growth and productivity and find surprisingly that input growth greatly predominates the contributions of it investment have increased in all regions but especially in industrialized economies and developing asia differences in per capita output are explained by differences in per capita input rather than by variations in productivity

an empirical model of firm entry with endogenous product type choices i describe a model of entry with endogenous product type choices these choices are formalized as the outcomes of a game of incomplete information in which rivals differentiated products have nonuniform competitive effects on profits i estimate the model for location choices in the video retail industry using a nested fixed point algorithm solution the results imply significant returns to product differentiation simulations illustrate the tradeoff between demand and intensified competition and the extent to which markets with more scope for differentiation support greater entry

imitation costs and patents an empirical study it has long been recognised that the costs of imitating new products have an important effect on the incentives for innovation in a market economy as arrow i962 and others have pointed out if firms can imitate an innovation at a cost that is substantially below the cost to the innovator of developing the innovation there may be little or no incentive for the innovator to carry out the innovation in their discussions of the innovation process economists frequently have called attention to the major role played by the costs of imitation but there has been little or no attempt to measure these costs to test various hypotheses concerning the factors influencing them or to estimate their effects in this paper we report some findings of what seems to be the first study of this topic in addition we present data regarding the effects of patents on imitation costs and on the rate of innovation

dynamic product positioning in differentiated product markets the effect of fees for musical performance rights on the commercial radio industry this article predicts how radio station formats would change if as was recently proposed music stations were made to pay fees for musical performance rights it does so by estimating and solving using parametric approximations to firms value functions a dynamic model that captures important features of the industry such as vertical and horizontal product differentiation demographic variation in programming tastes and multi station ownership the estimated model predicts that high fees would cause the number of music stations to fall significantly and quite quickly for example a fee equal to 10 of revenues would cause a 4 6 drop in the number of music stations within 2 1 2 years and a 9 4 drop in the long run the size of the change is limited however by the fact that many listeners particularly in demographics that are valued by advertisers have strong preferences for music programming publication abstract

time to build and fluctuations in bulk shipping abstract this paper explores the nature of fluctuations in world bulk shipping by quantifying the impact of time to build and demand uncertainty on investment and prices we examine the impact of both construction lags and their lengthening in periods of high investment activity by constructing a dynamic model of ship entry and exit a rich dataset of secondhand ship sales allows for a new estimation strategy resale prices provide direct information on value functions and allow their nonparametric estimation we find that moving from time varying to constant to no time to build reduces prices while significantly increasing both the level and volatility of investment jel g31 l11 l62 l92

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

wages and the intensity of labor effort efficiency wages versus compensating payments the distinction between efficiency wages and compensating payments is at best rather vague in both the theoretical and empirical literatures positing a relationship between wages and the intensity of labor effort while efficiency wages and compensating payments are both related to work intensity the mechanisms that generate these relationships are in each case quite distinct compensating payments exist in competitive labor markets to equalize overall compensation across identical workers with dissimilar working conditions workers who expend more labor effort must be paid more or they will seek employment elsewhere efficiency wages are employment rents paid by firms in order to ensure adequate labor effort these rents vary with the costs firms face in monitoring labor effort they cannot be competed away because without employment rents profit maximizing levels of work intensity would not be forthcoming in this paper we distinguish between the efficiency wage and compensating payments components in wage differences across workers and firms in the first section of the paper we use a theoretical model of optimal labor effort choice by workers and firms to make these two com

resolving the commitment versus flexibility trade off the role of resource accumulation lags we examine how time consuming resource accumulation influences the classic strategy trade off between commitment and flexibility in particular using 1975 95 data from the worldwide petrochemical

educational expansion and economic output in the united states 1890 1969 a production function analysis our research analyzes the effect of educational expansion on economic output in the united states from 1890 to 1969 in a departure from the individual level inferences often used in prior research we use an aggregate production function framework to estimate directly educational effects on economic output net of labor and capital the two basic factors of production using aggregate time series analyses we find that expansion at the secondary and doctorate levels was positively related to economic output in the years since 1933 we do not however find consistent evidence for effects of these or other levels of schooling from 1890 to 1928 consequently while we have found that educational expansion has made contributions to economic output the effects of education are more limited and time specific than shown in previous studies

detection and impact of industrial subsidies the case of world shipbuilding this paper provides a model based empirical strategy to i detect the presence and gauge the magnitude of government subsidies and ii quantify their impact on production reallocation across countries industry prices costs and consumer surplus i construct and estimate an industry model that allows for dynamic agents in both demand and supply and apply my strategy to world shipbuilding a classic target of industrial policy i nd strong evidence consistent with china having intervened and reducing shipyard costs by 15 20 corresponding to 5 billion us dollars between 2006 and 2012 the subsidies led to substantial reallocation of ship production across the world with japan in particular losing signi cant market share they also misaligned costs and production while leading to minor surplus gains for shippers

regulation and capacity competition in health care evidence from u s dialysis markets abstract this paper studies entry and capacity decisions by dialysis providers in the united states we estimate a structural model where providers make continuous strategic choices of capacity based on their private information about own costs and knowledge of the distribution of competitors private information we evaluate the impact on the market structure and providers profits under counterfactual regulatory policies that increase the costs or reduce the payment per unit of capacity we find that these policies reduce the market capacity as measured by the number of dialysis stations however the downward sloping reaction curve shields some providers from negative profit shocks in certain markets the paper also has a methodological contribution in that it proposes new estimators for bayesian games with continuous actions

being efficiently fickle a dynamic theory of organizational choice a central proposition in organization theory is that discrete organizational forms are matched to environmental conditions market strategies or exchange conditions this paper develops a contrary theoretical proposition we argue that efficiency may dictate modulating between discrete governance modes i e structural modulation in response to a stable set of exchange conditions if governance choices are discrete as much of organization theory argues then the consequent steady state functionality delivered by these organizational forms is itself discrete however if the desired functionality lies in between the steady state functionality delivered by two discrete choices then efficiency gains may be available by modulating between modes we develop an analytical model of structural modulation and examine factors that influence when modulation is ef ficiency enhancing as well as the optimal rate of modulation we conclude that under certain conditions structural modulation is efficiency enhancing further contrary to theories that highlight the potentially destructive consequences of inertia on organizational survival we identify important efficiencyyielding benefits of inertia

the costs of free entry an empirical study of real estate agents in greater boston this paper studies the consequences of xed commissions and low entry barriers in greater boston s real estate brokerage industry from 1998 2007 a period with substantial agent turnover we nd that entry is not associated with increased sales probabilities or reduced sales time instead it decreases the market share of experienced agents and reduces average service quality we develop a dynamic empirical model motivated by these patterns to study the extent of ineciency in the current system compared to alternatives to accommodate a large state space we approximate the value function using sieves and impose the bellman equation as an equilibrium constraint if commissions are cut in half there would be 40 fewer agents implying social savings of 23 of industry revenue and the average agent would facilitate 73 more transactions house price appreciation of 50 during our sample period accounts for a 24 increase in the number of agents and a 31 decline in average agent productivity finally improving information about past agent performance can increase productivity and generate signicant social savings

could good intentions backfire an empirical analysis of the bank deposit insurance the recent financial crisis led to the expansion of deposit insurance coverage in many countries we develop a structural model of the banking market in which banks act as financial intermediaries between consumers who have funds and businesses that seek loans and explore the implications of such policies for banks and depositors our results indicate the policy could erode market discipline and increase banks moral hazard as a result banks extend their lending to riskier loans than they would have in the absence of the policy we find this policy may even harm consumers moreover market competition magnifies the lack of market discipline and induces additional moral hazard for excessive risk taking counterfactuals indicate banks may reduce their deposit interest rates by 2 7 in a duopoly market and almost triple their risk caps under the new policy the estimated losses of depositors welfare are equivalent to at least a 3 27 drop in deposit interest rates data are available at https doi org 1

the productivity inflation nexus the case of the australian mining sector this paper examines the causal links between productivity growth and two price series given by domestic inflation and the price of mineral products in australia s mining sector for the period 1968 1969 to 1997 1998 the study also uses a stochastic translog cost frontier to generate improved estimates of total factor productivity tfp growth the results indicate negative unidirectional causality running from both price series to mining productivity growth regression analysis further shows that domestic inflation has a small but adverse effect on mining productivity growth thus providing some empirical support for australia s inflation first monetary policy at least with respect to the mining sector inflation in mineral price on the other hand has a greater negative effect on mining productivity growth via mineral export growth

competition and subsidies in the deregulated us local telephone industry the 1996 telecommunications act opened the monopolistic us local telephone industry to new entrants however substantial entry costs have prevented some markets from becoming competitive we study various subsidy policies designed to encourage entry we estimate a dynamic entry game using data on potential and actual entrants allowing for heterogeneous option values of waiting we find that subsidies to smaller markets are more cost effective in reducing monopoly markets but subsidies to only lower cost firms are less cost effective than a nondiscriminatory policy subsidies in only early periods reduce the option value of waiting and accelerate the arrival of competition

regulation imperfect competition and the u s abortion market the u s abortion market has grown increasingly concentrated recently while many states tightened abortion laws using data on abortion providers i estimate an equilibrium model of demand price competition entry and exit to capture the effect of regulation on industry dynamics estimates show regulations played an important role in determining the abortion market structure and evolution counterfactual simulations reveal increases in demand aimed regulation were the most important observed factor in explaining recent abortion declines simulating utah s regulatory regime nationally shows tightening abortion restrictions can increase abortions in equilibrium mainly through tilting the competitive landscape toward low price providers

identification and estimation of dynamic games when players beliefs are not in equilibrium this article deals with the identification and estimation of dynamic games when players beliefs about other players actions are biased that is beliefs do not represent the probability distribution of the actual behaviour of other players conditional on the information available first we show that an exclusion restriction typically used to identify empirical games provides testable non parametric restrictions of the null hypothesis of equilibrium beliefs in dynamic games with either finite or infinite horizon we use this result to construct a simple likelihood ratio test of equilibrium beliefs second we prove that this exclusion restriction together with consistent estimates of beliefs at two points in the support of the variable involved in the exclusion restriction is sufficient for non parametric point identification of players belief functions as well as useful functions of payoffs third we propose a simple two step estimation method we illustrate our model and methods using both monte carlo experiments and an empirical application of a dynamic game of store location by retail chains the key conditions for the identification of beliefs and payoffs in our application are the following 1 the previous year s network of stores of the competitor does not have a direct effect on the profit of a firm but the firm s own network of stores at previous year does affect its profit because the existence of sunk entry costs and economies of density in these costs and 2 firms beliefs are unbiased in those markets that are close in a geographic sense to the opponent s network of stores though beliefs are unrestricted and potentially biased for unexplored markets which are farther away from the competitors network our estimates show significant evidence of biased beliefs furthermore imposing the restriction of unbiased beliefs generates a substantial attenuation bias in the estimate of competition effects

real effects of information frictions when the states and the kingdom became united abstract this paper exploits a unique historical experiment to estimate how information frictions distort international trade the establishment of the transatlantic telegraph in 1866 i use newly collected data on cotton prices trade and information flows from historical newspapers and find that the average and volatility of the transatlantic price difference fell after the telegraph while average trade flows increased and became more volatile using a trade model in which exporters use the latest news about a foreign market to forecast expected prices i estimate the efficiency gains of the telegraph to be equivalent to 8 percent of export value jel d83 f12 f14 l96 n71 n73

towards an explanation of the productivity slowdown an acceleration deceleration hypothesis after two and a half decades of prosperous post war development western industrialised countries recently experienced a slowdown of economic growth and productivity advance together with an increase in the rates of inflation and unemployment in trying to explain this malaise we are looking at a diagnosis that could help us to identify early indicators of a future turnaround or some policy variables which deserve to be included in a therapeutic programme although we shall focus on what can be measured complying with the standards of the guild we shall not refrain from considering complex relationships which can be grasped only intuitively even if they include phenomena which lie beyond the limits of official statistics 2 the outcome may be soft economics but we find some consolation in the dictum that it is better to be vaguely right than to be precisely wrong

a dynamic model of entry and exit in a growing industry the potential demand in a new industry evolves over time demand is initially low but advertising by the industry s early entrants can speed up demand growth however there is intrinsic uncertainty of the demand level in each period and uncertainty of the demand evolution path which can be affected by the underlying economic environment we construct a dynamic model that features the stochastically and endogenously expanding demand of a new industry and we investigate the optimal entry and exit behavior of firms as the industry evolves we find that firms incentive to enter early depends critically on the cost that early entrants have to pay in developing the market when the cost is high and the benefit spills over to potential entrants firms have an incentive to wait and the probability of entry can increase with the number of incumbents under certain circumstances firms entry strategy is also influenced by the transition of economic states firms are more likely to enter under a state that shows the prospect of demand taking off soon we also find that in the early stage of an industry higher demand uncertainty can induce faster entry

firm expansion size spillovers and market dominance in retail chain dynamics we develop and estimate a dynamic game of strategic firm expansion and contraction decisions to study the role of firm size in future profitability and market dominance modeling firm size is important because retail chain dynamics are more richly driven by expansion and contraction than de novo entry or permanent exit additionally anticipated size spillovers may influence the strategies of forward looking firms making it difficult to analyze the effects of size without explicitly accounting for these in the expectations and hence decisions of firms expansion may also be profitable for some firms while detrimental for others thus we explicitly model and allow for heterogeneity in the dynamic link between firm size and profits as well as potential for persistent brand effects through firm specific unobservable factors as a methodological contribution we surmount the hurdle of estimating the model by extending a two step procedure that circumvents solving the game the first stage combines semipar

patterns of state productivity growth in the u s farm sector linking state and aggregate models this article focuses on agricultural productivity growth at both sector and state levels it does so in a way that preserves the economic integrity of national and state production accounts a model accounting for interstate transactions in farm goods links sectorwide and state specific measures of total factor productivity growth an interesting conclusion is that the smooth persistently positive trend typically observed for farm sector productivity growth masks considerable variation across states and regions the results also indicate that farm sector productivity growth is wholly a function of productivity trends in the individual states interstate shifts in production activity and resource reallocations have had little impact
