the growth of business firms facts and theory we refer to the framework developed by ijiri and simon 1977 and to the notion of independent submarkets sutton 1998 to provide a simple candidate explanation for the shape of the firm growth distribution based on a model of proportional growth at the level of both the introduction of new products by firms and their size dynamics we exploit the features of a unique longitudinal data set which covers the entire distribution of products and firms in the worldwide pharmaceutical industry to test the model at different levels of aggregation as well as at different time lags econometric investigations show that the model s predictions are in good agreement with empirical evidence jel l11 l65

understanding corporate coherence theory and evidence abstract multiproduct firms are perceived to be coherent in their scope yet there is no strong theoretical foundations to explain coherence in modern industrial organization theory this paper shows that as u s manufacturing firms grow more diverse they maintain a constant level of coherence between neighboring activities this finding runs counter to the idea that firms with many activities are generally more incoherent a framework is then presented which appeals to the nature of enterprise learning path dependencies and the nature of the selection environment to explain the ubiquity of coherent diversifiers

temporary income taxes and consumer spending both economic theory and casual empirical observation of the u s economy suggest that spending propensities from temporary tax changes are smaller than those from permanent ones but neither provides much guidance about the magnitude of this difference this paper offers new empirical estimates of this difference and finds it to be quite substantial the analysis is based on an amendment of the standard distributed lag version of the permanent income hypothesis that distinguishes temporary taxes from other income on the grounds that the former are more transitory this amendment which is broadly consistent with rational expectations leads to a nonlinear consumption function though the standard error is unavoidably large the point estimate suggests that a temporary tax change is treated as a 50 50 blend of a normal income tax change and a pure windfall over a 1 year planning horizon a temporary tax change is estimated to have only a little more than half the impact of a permanent tax change of equ

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

product quality product price and share dynamics in the german compact car market the present paper examines one of the central elements of evolutionary thinking the replicator dynamics mechanism using data on product characteristics of automobiles sold on the german domestic market over the period 2001 2006 we construct a fitness variable for each car model applying non parametric efficiency measurement techniques better known as data envelopment analysis dea the basic question we intend to answer is whether cars providing a higher quality price ratio for consumers tend to increase their market share compared to variants with lower quality price ratio for consumers the relationship between a car models fitness and its market performance is empirically tested in a regression framework the results show that the principle of growth of the fitter is working as suggested by evolutionary theory in particular we find that car models with considerably lower fitness than the market average lose whereas models with above average fitness gain additional market shares

technological regimes and schumpeterian patterns of innovation this paper proposes that the specific pattern of innovative activities in an industry can be explained as the outcome of different technological learning regimes a technological regime is defined by the particular combination of technological opportunities appropriability of innovations cumulativeness of technical advances and properties of the knowledge base building upon the distinction between schumpeter mark i and schumpeter mark ii industries this paper provides empirical estimates of the relationships between indicators of the schumpeterian patterns of innovation concentration of innovative activities stability in the hierarchy of innovators and importance of new innovators and indicators of the variables defining technological regimes

adjustment costs durables and aggregate consumption abstract previous tests of the permanent income hypothesis pih have focused on either non durables or durables expenditures in isolation this paper studies consumer purchases of non durables and durables as the outcome of a single optimization problem it is shown that with non separability in utility the presence of adjustment costs of changing durables stocks may affect the time series properties of both components of expenditure an econometric test of the pih based on the model developed in the paper is both more efficient and less prone to bias than those in some previous studies however this test confirms earlier rejections of the pih in aggregate quarterly data

permanent and transitory movements in labor income an explanation for excess smoothness in consumption many have argued that if labor income is difference stationary the permanent income hypothesis predicts that consumption should be relatively volatile in u s aggregate data labor income is well characterized as having a unit root however consumption turns out to be relatively smooth this anomaly is known as deaton s paradox i resolve deaton s paradox by providing decompositions of labor income into permanent and transitory components these preserve the univariate dynamic properties of labor income however when agents distinguish permanent and transitory movements in their labor income as the rational expectations hypothesis asserts they should the permanent income hypothesis correctly predicts the observed smoothness in consumption

innovation diversity and diffusion a self organisation model a number of features of innovation diffusion are identified appropriability diversity expectations selection learning and spillover externalities a dynamic model is formul ated to embed the diffusion question into a more general framework of disequilibrium competition the model incorporates distinct vintage structures reflecting a change in technological trajectory learning by using a nd expectations driven investment rules of thumb simulation studies reveal robust quasi logistic curves but a complicated pattern of net market share gains and losses uncertainty regarding the rationality of early or late adoption it is argued ensures that the requisite behavioral variety is present to generate these diffusion patterns copyright 1988 by royal economic society

corporate growth and industrial structures some evidence from the italian manufacturing industry this work analyses the properties of corporate growth in a large longitudinal sample of italian manufacturing firms in particular it focuses on the statistical properties of growth rates and on the influence of proxies for relative efficiency upon relative growth in line with previous work the emergence of fat tails in growth rate distributions and the idiosyncratic nature of autocorrelation coefficients confirm the existence of a structure in the growth process richer than the one normally assumed by the gibrat law hypothesis and suggest the presence of firm specific drivers of growth at the same time there is a remarkable puzzle concerning the absence of any negative relationship between size and growth variance and only weak influences of relative efficiencies upon growth dynamics

a reexamination of friedman s consumption puzzle the different average and marginal consumption propensities estimated from time series data constitute a classic puzzle of the theory of consumption this article argues that if consumption and income possess a common stochastic trend and thus are cointegrated both the average propensity to consume apc and the marginal propensity to consume mpc will be consistent but biased in small samples upon correcting for this small sample bias the puzzling discrepancies between the apc and the mpc estimated using annual data for the united states from 1897 to 1949 become substantially smaller this supports an alternative resolution of the puzzle based on the theory of cointegration

trade openness and the changing water polluting intensity patterns of dirty and clean industrial sectors abstract this study analyzes the economic activity bod biochemical oxygen demand relationships of the so called dirty and clean water polluting industries during the period of 1995 2005 the results indicate that the economic activity environment trade off of dirty and clean industrial sectors has been altered during the period of study on average pollution intensive dirty industries in the poorer nations were found to benefit in terms of bod emissions from extra exports and openness to trade the opposite was true for clean sectors where increased trade openness seems to have contributed to a wider gap between poorer and richer nations pollution intensities with openness to trade skewing innovations away from the clean industries industrial sectors in which the poorer countries specialize the classical model of opening the economy and lifting barriers to technology adoption will not be enough to improve the poorer nations water quality policies that induce innovation by reducing the cost and increasing the return on innovation particularly on r d activities in which the poorer countries have a comparative advantage will be necessary in order to improve their economic activity environment relationship

gibrat s law and diversification this article presents an analysis of the growth patterns of the worldwide top 200 firms in the pharmaceutical industry a test of the gibrat s law of proportionate effect is performed and we find in line with previous literature a violation concerning the variance of growth using disaggregated data on sub markets we are however able to show that this violation can be completely accounted for by a diversification effect namely a scale relation between the number of sub markets in which a firm is active and its size to interpret these findings we propose a stochastic branching model of firm diversification consistent with a notion of cumulative corporate competences

the footprint of evolutionary processes of learning and selection upon the statistical properties of industrial dynamics evolutionary theories of economic change identify the processes of idiosyncratic learning by individual firms and of market selection as the two main drivers of the dynamics of industries are such processes able to account for the statistical regularities which industrial structures and dynamics display in this work we address this question by means of a simple multi firm model formalizing the mechanisms of learning and selection as such despite its simplicity the model is able to robustly reproduce an ensemble of empirical stylized facts including ample heterogeneity in productivity distributions persistent market turbulence and fat tailed distribution of growth rates

international spillovers and water quality in rivers do countries free ride transboundary spillovers may degrade environmental quality if countries free ride this paper examines the extent of such degradation in water quality in international rivers using data from river monitoring stations in the un s global emissions monitoring system gems it compares pollution levels in international and domestic rivers the results suggest that free riding may substantially increase pollution in international rivers but the estimates are sensitive to the inclusion of country effects this abstract was borrowed from another version of this item

scaling in economics a reader s guide this paper discusses examples of scaling laws in economics and finance it argues that these regularities in data are useful for disciplining theory formation estimation of the conditional predictive distribution and estimation of impulse response functions is a main goal of econometric work scaling type regularities give useful information on the underlying data generating process the ability of scaling laws to suggest lines of potentially fruitful research was illustrated by the suggestion of several speculative research projects in this paper most importantly the paper stresses the challenges that face empirical and theoretical researchers who wish to make use of scaling law type regularities to improve econometric identification of the underlying causal data generating mechanism copyright 1999 by oxford university press

explaining the distribution of firm growth rates empirical analyses on aggregated datasets have revealed a common exponential behavior in the shape of the probability density of corporate growth rates we present clear cut evidence on this topic using disaggregated data we explain the observed regularities proposing a model in which firms ability to take up new business opportunities increases with the number of opportunities already exploited a theoretical result is presented for the limiting case in which the number of firms and opportunities go to infinity moreover using simulations we show that even in a small industry the agreement with asymptotic results is almost complete

comparative analysis of firm demographics and survival evidence from micro level sources in oecd countries in this paper we present cross country evidence on firm size distribution firm demographic and post entry performance for 10 oecd countries we use harmonized firm level data drawn from business registers or social security records these data enable international comparisons and the identification of idiosyncratic country effects while average firm size differs across countries due to both sectoral specialization and within sector characteristics we find similar degrees of firm churning across countries in most of them about 20 of firms enter and exit most markets every year and about 20 40 of entering firms fail within the first 2 years of life however post entry growth of successful entrants is much higher in the usa than in europe which may be indicative of barriers to firm growth as opposed to barriers to entry

trade the pollution haven hypothesis and the environmental kuznets curve examining the linkages abstract this paper examines the extent to which the ekc inverted u relationship can be explained by trade and specifically the migration or displacement of dirty industries from the developed regions to the developing regions the pollution haven hypothesis phh using detailed data on north south trade flows for pollution intensive products the evidence for the phh is assessed emissions of 10 air and water pollutants are then estimated controlling for trade openness structural change and dirty north south trade flows evidence of pollution haven effects is found although such effects do not appear to be widespread and appear to be relatively small compared to the roles played other explanatory variables

productivity market selection and corporate growth comparative evidence across us and europe this paper analyses the patterns of market selection in manufacturing industries of france germany uk and usa we first disentangle the contribution to industry level productivity growth of within firm productivity changes and between firm reallocation of shares the evidence corroborates the notion that within firm learning prevails over market selection forces with larger firms driving such innovation and learning processes second we address the strength of selection by exploring to what extent firm growth rates are shaped by relative productivity levels as compared to variation thereof our key finding is that although changes in relative efficiency have a greater impact on growth than relative efficiency levels there is an overall weak relationship between productivity and growth and therefore a weak power of selection forces in all countries the results hold across firms of different size but we also find that selection bites more on smes

dirty industries patterns of change in industrial countries this article concerns itself with the environmental role of heavily polluting industries since 1970 analysing its development in 11 basic industries as well as electricity production and road transport in 32 industrial countries it argues for a green industrial policy demonstrating that other mitigations of environmental pressure in industrial countries end of pipe treatment relocation to the third world structural change in the industrial sector and even environmentally oriented modernization have so far been unable to solve the problems of dirty industries although some approaches have shown some promise

public policies and the art of catching up matching the historical evidence with a multicountry agent based model in this paper we study the effects of industrial policies on international convergence using a multi country agent based model which builds upon dosi et al 2019b the model features a group of microfounded economies with evolving industries populated by heterogeneous firms that compete in international markets in each country technological change is driven by firms activities of search and innovation while aggregate demand formation and distribution follows keynesian dynamics interactions among countries take place via trade flows and international technological imitation we employ the model to assess the different strategies that laggard countries can adopt to catch up with leaders market friendly policies industrial policies targeting the development of firms capabilities and rd protectionist policies focusing on tariffs only we find that markets cannot do the magic in absence of government interventions laggards will continue to fall behind on the contrary industrial policies can successfully drive international convergence among leaders and laggards while protectionism alone is not necessary to support catching up and countries get stuck in a sort of middle income trap finally in a global trade war where developed economies impose retaliatory tariffs both laggards and leaders are worse off and world productivity growth slows down

firm growth and laplace distribution the importance of large jumps abstract recent empirical studies have shown that firm growth rate distribution is not gaussian but closely follows a laplace distribution this robust feature of the growth rate distribution challenges existing models based on gibrat s model because it predicts a gaussian distribution first we analyze more than 100 000 japanese firms and empirically show that the laplace shape can be observed for the japanese firms then by using the theory of stochastic processes we theoretically show that the absence of jumps causes the discrepancy between gibrat s model and the laplace shape in particular based on the laplace shape and the law of proportionate effect we show that the firm growth process is a jump process in other words firm growth cannot be explained by the consequence of many small shocks but is determined by a few large jumps the widely observed laplace distribution reflects this jump property of firm growth dynamics

causes and consequences of hysteresis aggregate demand productivity and employment in this work we develop an agent based model where hysteresis in major macroeconomic variables e g gross domestic product productivity unemployment emerges out of the decentralized interactions of heterogeneous firms and workers building upon the schumpeter meeting keynes family of models cf in particular dosi et al 2016b 2017c we specify an endogenous process of accumulation of workers skills and a state dependent process of firms entry indeed hysteresis is ubiquitous however this is not due to market imperfections but rather to the very functioning of decentralized economies characterized by coordination externalities and dynamic increasing returns so contrary to the insider outsider hypothesis blanchard and summers 1986 the model does not support the findings that rigid industrial relations may foster hysteretic behavior in aggregate unemployment on the contrary this contribution provides evidence that during severe downturns and thus declining aggregate demand phenomena like decreasing investment and innovation rates skills deterioration and declining entry dynamics are better candidates to explain long run unemployment spells and reduced output growth in that more rigid labor markets may well dampen hysteretic dynamics by sustaining aggregate demand thus making the economy more resilient

modes of knowledge accumulation entry regimes and patterns of industrial evolution this paper explores the interplay between entry selection and innovative learning as determinants of industrial evolution it proposes a model aimed at capturing some essential features of learning and competition as drivers of the dynamics using both analytical and numerical techniques the paper disentangles possible generic properties which robustly hold for a wide range of parameterizations in particular the paper identifies different generic evolutionary archetypes defined by characteristic interactions between entry exit regimes learning and industrial structures

exploring the processes of firm growth evidence from a vector auto regression this article offers many new insights into the processes of firm growth by applying a vector autoregression model to longitudinal panel data on french manufacturing firms we observe the coevolution of key variables such as growth of employment sales gross operating surplus and labor productivity growth preliminary results suggest that employment growth is succeeded by the growth of sales which in turn is followed by growth of profits generally speaking however growth of profits is not followed by much employment growth or sales growth quantile regressions highlight some asymmetries between negative growth and fast growth firms

what drives markups evolutionary pricing in an agent based stock flow consistent macroeconomic model this paper studies coordination between firms in a multi sectoral macroeconomic model with endogenous business cycles firms are both in competition and interdependent and set their prices with a markup over unit costs markups are heterogeneous and evolve under market pressure we observe a systematic coordination within firms in each sector and between each sector the resulting pattern of relative prices are consistent with the labor theory of value those emerging features are robust to technology shocks

towards an economic theory of the multiproduct firm this paper outlines a theory of the multiproduct firm important building blocks include excess capacity and its creation market imperfections and the peculiarities of organizational knowledge including its fungible and taut character a framework is adopted in which profit seeking firms are seen to diversify in order to avoid the high transactions costs associated with using various markets to trade the services of various specialized assets neoclassical explanations of the multiproduct firm are shown to be seriously deficient

diversification ricardian rents and tobin s q according to prevailing theory firms diversify in response to excess capacity of factors that are subject to market failure by probing into the heterogeneity of these factors we develop the corollary that firms that elect to diversify most widely should expect the lowest average rents an empirical test with tobin s q as the measure of rents is consistent with this theory

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

production theory accounting for firm heterogeneity and technical change the paper presents a new framework to assess firm level heterogeneity and to study the rate and direction of technical change building on the analysis of revealed short run production functions by hildenbrand 1981 we propose the normalized volume of the zonotope composed by vectors firms in a narrowly defined industry as an indicator of inter firm heterogeneity moreover the angles that the main diagonal of the zonotope form with the axes provide a measure of the rates and directions of technical change over time the proposed framework can easily account for n inputs and m outputs and crucially the measures of heterogeneity and technical change do not require many of the standard assumptions from production theory

invariances and diversities in the evolution of manufacturing industries this work explores and compares some basic properties of corporate growth process at both aggregate manufacturing level and disaggregated sectoral levels using an extensive dataset on italian manufacturing firms we investigate which properties of firm growth dynamics are robust under disaggregation we compare the results obtained with three different definitions of firm size namely total sales number of employees and value added our analysis suggests that while different sectors are characterized by significant differences in firm size distributions in the degrees of concentration and in the autoregressive structure of the growth processes there are also regularities which hold across all of them such as the approximate unit root nature of the growth process and the power exponential shape of the growth rates density together these stylized facts suggest challenging puzzles on the drivers of corporate growth and the resulting industrial structures
