price setting supergames with capacity constraints this paper examines the role of industry capacity in enforcing collusion in the context of repeated games for a fixed capacity per firm it is shown that changes in the number of firms have a non monotone effect on the best enforceable cartel price this is due to the fact that while an additional firm lowers the share that each of the other firms enjoys at the collusive price it also increases the losses to each firm should the cartel fail

international search behavior of business group affiliated firms scope of institutional changes and intragroup heterogeneity this paper investigates whether and when affiliation to business groups enables or constrains firms international search behavior during institutional transitions we theorize that given the unique structure and complex form of business group organizations the search behavior of affiliated firms is influenced by the degree of misalignment in outlook at the group and affiliate levels of management we identify the scope of institutional changes business group attributes and affiliate characteristics as sources of such misalignment the results from panel data on 298 firms from the indian pharmaceutical industry for the 1992 2007 period show that the constraining effects of business group affiliation are observed only when institutional changes are specific to the affiliates industry and not when broad institutional changes affect the business group as a whole moreover we observe heterogeneity in the search behavior of group affiliated firms first the degree of misalignment is greater in the case of affiliates belonging to older business groups and those that are more distant in terms of age and industry since the group s founding second by contrast and suggesting an alignment in outlook we find that affiliated firms that occupy a prominent position within a group or industry are able to bargain for and receive attention and support from the business group to undertake international search our findings have implications for research on the role of business groups in a changing institutional context and for the strategic adaptation of firms embedded in complex organizational and institutional settings

advertising learning and consumer choice in experience good markets an empirical examination this article empirically analyzes different effects of advertising in a nondurable experience good market a dynamic learning model of consumer behavior is presented in which i allow both informative effects of advertising and prestige or image effects of advertising this learning model is estimated using consumer level panel data tracking grocery purchases and advertising exposures over time empirical results suggest that in this market advertising s primary effect was that of informing consumers the estimates are used to quantify the value of this information to consumers and evaluate the welfare implications of an alternative advertising regulatory regime

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

generic drug industry dynamics both the economics literature and the business press suggest that a typical pattern for a new industry or what jovanovic and macdonald 1994 call an invention i s to have an initial phase in which a small number of firms each earn significant profits followed by a phase in which rapid entry of new firms leads to increased competition and dissipation of some of those profits often accompanied by a shakeout whereby only a few large firms remain especially if subsequent innovations increase the optimal scale although this pattern seems to characterize many industries the length of time during which early movers retain their profits how prices adjust during the entry process and the

sweatshops economic analysis and exploitation as unfairness the economic and moral defense of sweatshops given by powell and zwolinski j bus ethics 107 449 472 2012 has been criticized in two recent papers coakley and kates j bus ethics 117 553 558 2013 focus on putative weaknesses in the logic of powell s and zwolinski s argument preiss bus ethics quart 24 1 55 82 2014 argues that even granting the validity of their economic argument powell s and zwolinski s defense is without force when viewed from a kantian republican viewpoint we are concerned that sweatshop critics have misinterpreted the economic literature and overstated the conclusions that follow from their ethical premises we show that the best understanding of the current economic literature supports powell s and zwolinski s conclusions about the negative effects of sweatshop wage regulation and that it is unreasonable to reject economic analysis in moral argument against sweatshops even from a kantian perspective additionally we defend the theory of exploitation as unfairness given by wertheimer exploitation 1996 and show how economic analysis can be applied to that theory to identify cases of sweatshop exploitation

organizational inertia and momentum a dynamic model of strategic change this study provides an empirical test of hannan and freeman s theory of structural inertia we examined the changes organizations undertook in response to a major environmental change in addition

exploiting injustice in mutually beneficial market exchange the case of sweatshop labor mutually beneficial exchanges in markets can be exploitative because one party takes advantage of an underlying injustice for instance employers of sweatshop workers are often accused of exploiting the desperate conditions of their employees although the latter accept the terms of their employment voluntarily a weakness of this account of exploitation is its tendency for over inclusiveness certainly given the prevalence of global and domestic socioeconomic inequalities not all exchanges that take place against background injustices should be considered exploitative this paper offers a framework to identify exploitation in mutually beneficial exchange focusing on the case of sweatshop labor it argues that an employer can be viewed as taking unfair advantage of an underlying injustice if and only if the employer s surplus from the exchange in the unjust state of affairs exceeds the surplus it could maximally obtain in a just state of affairs the paper illustrates the applicability of this framework using three different conceptions of justice and argues that it is superior to microlevel accounts of exploitation that regard background justice as irrelevant the paper concludes by describing some normative implications that follow from judging an exchange exploitative

the impact of minimum wages in mexico and colombia there are diverging views about how minimum wages affect labor markets in developing countries advocates of minimum wages hold that they redistribute resources in a welfare enhancing way and can thus reduce poverty improve productivity and foster growth opponents on the other hand contend that minimum wage interventions result in a misallocation of labor and lead to depressed wages in the very sectors the rural and informal urban sectors where most of the poor are found with the effect of wasting resources and reducing the growth rate data from colombia and mexico for the 1980s provide an opportunity to evaluate the impact of minimum wages in mexico in the 1980s the minimum wage fell in real terms roughly 45 percent by 1990 mexico s minimum wage was about 13 percent of the average unskilled manufacturing wage during the same period the minimum wage in colombia increased at nearly the same rate reaching roughly 53 percent of the average unskilled wage the author charts how the mandated minimum wage affected the demand for skilled and unskilled labor in both countries during that decade findings are as follows in mexico minimum wages have had virtually no effect on wages or employment in the formal sector the main reason the minimum wage is not an effective wage for most firms or workers in the informal sector in turn there is considerable noncompliance with the mandated minimum wage especially among part time and female workers as a result significant numbers of workers are paid at or below minimum wages in colombia minimum wages have a much stronger impact on wages judging from their proximity to the average wage and both cross section and time series estimates the estimates imply that the elasticity of low paid unskilled employment with respect to minimum wages is in the range of 2 to 12 percent

invited paper learning models an assessment of progress challenges and new developments learning models extend the traditional discrete choice framework by postulating that consumers have incomplete information about product attributes and that they learn about these attributes over time in this survey we describe the literature on learning models that has developed over the past 20 years using the model of erdem and keane as a unifying framework erdem t keane m 1996 decision making under uncertainty capturing dynamic brand choice processes in turbulent consumer goods markets marketing sci 15 1 1 20 we describe how subsequent work has extended their modeling framework and applied learning models to a wide range of different products and markets we argue that learning models have contributed greatly to our understanding of consumer behavior in particular in enhancing our understanding of brand loyalty and long run advertising effects we also discuss the limitations of existing learning models and potential extensions one key challenge is to disentangle learning as a source of

organizational innovation and its effects organizational innovation its persistence its relationship with technological innovation and their influence on firm performance remain under researched these issues are investigated using an integrated firm level data set obtained from two recent waves of the norwegian community innovation survey cis 3 and 4 and firms financial accounts a heckman two step estimation to ensure against potential sample selection bias was used to demonstrate that between 1999 and 2004 a number of norwegian firms were persistent in organizational innovation and this persistence raised the positive effects of organizational innovation on their performance the results also reveal that many firms undertook and benefited from different types of organizational innovation and such benefits were increased by the combinative effect of organizational and technological innovation the study also found that older and larger firms are more inclined to attempt organizational change while smaller firms are more able to benefit copyright 2012 the author 2012 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

capital market development and firm restructuring during an economic shock we conceptualize capital markets in terms of resource access and governance and argue that more developed capital markets facilitate firm restructuring through more effective provision of capital and governance of transactions we then develop a contingency model that specifies that the effects of capital market development on restructuring vary by 1 types of restructuring 2 the nature of the economic environments and 3 firms access to resources we evaluate a broad range of restructuring actions among independent firms and business group affiliates in singapore and south korea before and during the economic shock of 1998 1999 results support our predictions of the impact of capital market development and of contingencies and highlight the value of incorporating an external capital markets perspective to complement internally focused theoretical explanations for firm restructuring

pricing patent loss and the market for pharmaceuticals dustry the drug price competition and patent term restoration act of 1984 very clearly reflects the determination of policy makers to simultaneously address issues of price control and technical progress the 1984 act increased returns to innovation by extending the period of patent protection to take into account the time between receipt of a patent and food and drug administration fda approval of a drug for sale in the market the 1984 act also reduced the testing requirements for approval of new generic brands of existing chemical entities thus reducing entry barriers in markets where patents have expired the expected outcome from eased entry conditions for generic substitutes was substantially enhanced price competition and lower prices for brand name drugs in fact prices for brand name drugs have tended to increase following entry by generics wagner and duffy 28 examined price changes for top selling generics and name brands they show substantial price increases in brand name prices accompanying large reductions in generic prices as entry of generics occurs grabowski and vernon 9 examined data on 18 major orally administered rug products subject to generic competition between 1983 and 1987 and found that the name brand price increased by an average of 7 one year subsequent to generic entry and 11 two years following generic entry

reference pricing competition and pharmaceutical expenditures theory and evidence from a natural experiment abstract we study the impact of regulation on competition between brand names and generics and pharmaceutical expenditures using a unique policy experiment in norway where reference pricing rp replaced price cap regulation in 2003 for a sub sample of off patent products first we construct a vertical differentiation model to analyze the impact of regulation on prices and market shares of brand names and generics then we exploit a detailed panel data set at product level covering several off patent molecules before and after the policy reform off patent drugs not subject to rp serve as our control group we find that rp significantly reduces both brand name and generic prices and results in significantly lower brand name market shares finally we show that rp has a strong negative effect on average molecule prices suggesting significant cost savings and that patients copayments decrease despite the extra surcharges under rp

dynamic demand for new and used durable goods without physical depreciation the case of japanese video games we develop a new dynamic demand model for new and used durable goods and quantify the impact of used goods markets on producers profits and consumer welfare

generics and new goods in pharmaceutical price indexes drug prices and their rate of inflation are a major focus of current policy debates on u s health care in this paper we show that where patent expiration and generic entry are significant as they are for many important classes of drugs movements in the official price indexes may be poor indicators of the actual prices paid and the resulting changes in consumer welfare when a drug goes off patent those consumers who regard the branded and generic versions as more or less perfect substitutes experience a substantial price decline and concomitant welfare gain which the current methods used by the statistical agencies fail to capture we suggest a number of alternative ways of proceeding although our computations are based on a limited number of cases they imply that the overall rate of inflation in drug prices may be quite seriously overstated while generic pharmaceuticals are the topic of our calculations the problem discussed is also of wider importance generic drugs are a special and possibly easy case

price competition in pharmaceuticals the case of anti infectives a fundamental question in industrial organization regards the relationship between price and the number of sellers this relationship has been particularly important in the pharmaceutical industry where legislative changes were specifically designed to foster competition previous research on the pharmaceutical industry has shown generic entry has a mixed impact generic prices fall rapidly with generic entry whereas branded prices tend to increase or decrease only slightly using more complete data focused on one segment of the pharmaceutical industry anti infectives we find that the relationship between pharmaceutical prices and the number of sellers is more like that found in other industries jel l11 l65 d4

platform pricing at sports card conventions platform pricing at sports card conventions we study a new data set of us sports card conventions in order to evaluate the pricing theory of two sided markets conventions are two sided because organizers must set fees to attract both consumers and dealers we have detailed information on consumer price dealer price and since most conventions are local the market structure for conventions we present several findings first consumer pricing decreases with competition at any reasonable distance but pricing to dealers is insensitive to competition and in longer distances even increases with competition second when consumer price is zero and thus constrained dealer price decreases more strongly with competition these results are compatible with existing models of two sided markets but are difficult to explain without such models

dynamic oligopoly with capacity adjustment costs abstract the literature on strategic investment emphasized the case of completely irreversible investment this paper considers an oligopoly model in which investment is reversible and capacity is subject to adjustment costs an n player linear quadratic differential game is analyzed existence and characterization results for perfect equilibrium feedback strategies are provided feedback strategies provide incentives for each player to invest strategically so as to preempt subsequent expansion by rivals a larger set of perfect equilibria is constructed by using memory dependent trigger strategies equilibria of this type are shown to support joint value maximization for some initial states and asymmetric steady states

export subsidies under dynamic duopoly abstract in this paper i analyze an export subsidy game under a dynamic cournot duopoly using a discrete time markov equilibrium model of dynamic cournot duoply according to maskin and tirole 1987 assuming a linear demand function i will show that under a dynamic duopoly 1 firms are more sensitive to changes in export subsidies 2 the equilibrium export subsidy in an export subsidy game is smaller 3 the output at the subsidy equilibrium is larger than a static duopoly with lower subsidy and higher output the welfare in countries under a dynamic duopoly is higher than a static duopoly

entry into pharmaceutical submarkets a bayesian panel probit analysis summary we study entry into pharmaceutical submarkets by using a dynamic panel probit model we develop a bayesian version of wooldridge s approach to dealing with unobserved heterogeneity we distinguish between greenfield entry entry with first product and undifferentiated entry which may take the form of introducing further products we extend the standard reduced form model to consider company size in the submarket and across all submarkets we find that greenfield and undifferentiated entries have different determinants that global and submarket size measures have different effects and that sunk costs often have positive effects on entry due to a commitment mechanism copyright 2012 john wiley sons ltd

price dispersion and incomplete learning in the long run abstract in each period a seller chooses a price and the customer for that period buys either one unit or nothing the relationship between price and purchase probability is one of two linear functions it is shown that the seller behaving optimally does not necessarily learn which function is the actual relationship since there can be a positive probability of sequences of prices converging to the price at which the two functions give the same purchase probability

the economics of predation what drives pricing when there is learning by doing predatory pricing a deliberate strategy of pricing aggressively in order to eliminate competitors is one of the more contentious areas of antitrust policy and its existence and efficacy are widely debated the purpose of this paper is to formally characterize predatory pricing in a modern industry dynamics framework that endogenizes competitive advantage and industry structure our framework encompasses important phenomena such as learning by doing network effects switching costs dynamic demand and certain types of adjustment costs due to its prominent role in legal cases involving alleged predation we examine learning by doing in more detail we first show that predation like behavior arises routinely in our learning by doing model equilibria involving predation like behavior typically coexist with equilibria involving much less aggressive pricing to disentangle predatory pricing from mere competition for efficiency on a learning curve we next decompose the equilibrium pricing condition and develop alternative characterizations of a firm s predatory pricing incentives we finally measure the impact of these incentives on industry structure conduct and performance we show that forcing a firm to ignore the predatory incentives in setting its price can have a large impact and that this impact stems from eliminating equilibria with predation like behavior along with the predation like behavior however a fair amount of competition for the market is eliminated

a dynamic oligopoly structural model for the prescription drug market after patent expiration this article incorporates consumer learning and heterogeneity into a dynamic oligopoly model for the prescription drug market in the model both firms and patients need to learn the generic qualities via patients experiences generic firms entry decisions are endogenous but their entry timings depend on a random approval process i apply the model to examine the impact of shortening the expected generic approval time although this policy experiment brings generics to the market sooner it increases a potential entrant s likelihood of entering a crowded market and hence could reduce the total number of generic entrants and consumer welfare

global apparel production and sweatshop labour can raising retail prices finance living wages this paper provides some empirical evidence on issues raised by the global antisweatshop movement we first consider the relationship between wage and employment growth finding no consistent trade off between them we then measure the share of labour costs in the production of garments in the us and mexico we find that the retail price increases necessary to absorb the costs of raising wages substantially are small well within the range of price increases that polls suggest us consumers are willing to pay we close by considering some implications of these results copyright 2004 oxford university press

a foundation for markov equilibria in sequential games with finite social memory we study stochastic games with an infinite horizon and sequential moves played by an arbitrary number of players we assume that social memory is finite every player except possibly one is finitely lived and cannot observe events that are sufficiently far back in the past this class of games includes games between a long run player and a sequence of short run players and games with overlapping generations of players an equilibrium is purifiable if some close by behaviour is consistent with equilibrium when agents payoffs in each period are perturbed additively and independently we show that only markov equilibria are purifiable when social memory is finite thus if a game has at most one long run player all purifiable equilibria are markov

a theory of dynamic oligopoly iii cournot competition abstract we study the markov perfect equilibrium mpe of an alternating move infinite horizon duopoly model where the strategic variable is quantity we exhibit a pair of difference differential equations that when they exist differentiable mpe strategies satisfy for quadratic payoff functions we solve these equations in closed form and demonstrate that the mpe corresponding to the solution is the limit of the finite horizon equilibrium as the horizon tends to infinity we conclude with a discussion of adjustment costs and endogenization of the timing

the dynamic spillovers of entry an application to the generic drug industry this paper examines whether experience from entry in one market can potentially enhance profitability at a future market opportunity for a related product we formulate and estimate a dynamic game of entry in which forward looking firms make decisions not just based on present benefits of past entry but also anticipating potential future benefits of current entry dynamic spillovers of entry are incorporated through a firm specific unobservable to the researcher cost that depends on past entry decisions the unobserved costs may also be serially persistent thus the model allows for firm specific unobserved heterogeneity that evolves based on firm actions the challenge of estimating a dynamic game with serially correlated unobserved state variables subject to endogenous feedback is overcome by embedding a particle filter based technique in a nested fixed point algorithm using an application to a stylized model of entry in the generic pharmaceutical industry we underscore the motivation for the model specification and the methodology developed our estimates imply positive spillover effects of entry moreover these spillovers suggest heterogeneity not just across firms but also within firms over time based on their history of entry decisions our results illustrate that entry may potentially provide firms with additional strategic advantage in later markets and that entry spillovers may be an important factor to consider in the equilibrium evolution of the generic drug industry the web appendix is available at https doi org 10 1287 mnsc 2016 2648 this paper was accepted by j miguel villas boas marketing

momentum or deceleration theoretical and methodological reflections on the analysis of organizational change research on organizational change has consistently shown that prior change increases the probability of further change which supports the view that repetitive momentum governs change processes we challenge this consensus offering theoretical arguments for the opposite change propensity decreases as changes accumulate we argue that unobserved heterogeneity in the inherent change propensity of organizations has biased prior results analyses of three data sets yielded positive effects of prior change on further change when we used the methodology of earlier studies however fixed effects models that control for heterogeneity yielded negative effects we conclude that deceleration not repetitive momentum governs change processes

ownership size and the formal structure of organizations evidence from us public and private firms 1992 2002 this study considers the effects of i ownership structure ii prior size dynamics of growth and decline and iii organizational size on changes in the formal structure of organizations using a broad sample of almost 70 000 us public and private firms i test the arguments by estimating conditional logistic regressions using as dependent variables two dimensions of organizational structural differentiation the number of formal subunits and hierarchical levels the findings show that public firms are more likely to elaborate structurally but less likely to simplify their structural differentiation as organizations grow decline in size they apparently tend to increase decrease their degree of structural differentiation however for a given change in size the level of structural differentiation is less likely to increase during growth than it is to decrease during decline indicating an asymmetric pattern i also find that organizational size can serve as a facilitator or inhibitor for structural change depending on the direction of change finally i find that the asymmetric pattern of growth and decline works differently for large and small firms the same proportional increase in size is more likely to generate structural differentiation for larger firms than for smaller firms but the same proportional decrease in size has a smaller likelihood of causing structural de differentiation for larger firms than for smaller firms copyright 2009 the author 2009 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

aggregate pattern of time dependent adjustment rules ii strategic complementarity and endogenous nonsynchronization abstract this paper provides an explanation for an important institutional feature of staggered time dependent adjustment rules assumed in a number of macroeconomic models it identifies strategic complementarity as the crucial factor leading to nonsynchronized decisions in a game theoretic framework the paper first shows that nonsynchronization is the equilibrium outcome in an infinite horizon game in which strategic complementarity is present whether the players choose predetermined or fixed actions by pursuing the interpretation of a nonsynchronized move dynamic game as a series of games with symmetric stackelberg leadership it is further suggested that the relationship between strategic complementarity and the benefit to the stackelberg follower provides the insight to the game theoretic explanation of nonsynchronization the results of this paper reveal a link between strategic complementarity and nonsynchronization two important macroeconomic features journal of economic literature classification numbers e30 l16

higher wages for sustainable development employment and carbon effects of paying a living wage in global apparel supply chains abstract in this paper we explore how paying a living wage in global supply chains might affect employment and carbon emissions sustainable development goals 8 and 13 previous work has advocated using wage increases for poorer workers to increase prices for wealthier consumers thereby reducing consumption and associated environmental damage however the likely effects of such an approach remain unclear using an input output framework extended with income and demand elasticities we estimate the employment and carbon effects of paying a living wage to brazilian russian indian and chinese bric workers in the western european clothing supply chain we find negligible effects on carbon emissions but a substantial increase in bric employment under 3 scenarios of consumer behaviour changes in western european consumption lead to small decreases in global carbon emissions and bric employment however the increase in bric wages increases demand in bric this increased demand increases production which largely cancels out the carbon savings and generates net increases in bric employment we conclude by arguing that paying higher wages in global supply chains represents a good but not sufficient step toward achieving the sustainable development goals

interdependent behavior in foreign direct investment the multi level effects of prior entry and prior exit on foreign market entry this paper examines the interdependent foreign market entry decisions of multinational corporations mncs based on the argument that legitimacy and competition are two important forces in foreign market entry decisions we hypothesize that an mnc s market entry decisions are influenced by its own prior entry and prior exit decisions and those of other mncs we examine this general proposition at four levels of analysis the host country global industry an industry that spans host countries local industry an industry that is separately defined within each host country and parent firm level our analysis of a panel data of over 4000 market entry decisions that were made by japanese mncs shows that an mnc s market entry decision has a stronger inverted u shaped relationship with the prior entry and exit decisions of other mncs at the local industry level than the prior entry and exit decisions of other mncs at the host country and global industry levels we also find that both the prior entry and prior exit decisions of an mnc have a marginal influence on its own subsequent market entry decisions at the parent firm level

a dynamic oligopoly with collusion and price wars we provide a collusive framework with heterogeneity among jirms investment entry and exit it is a symmetric information model in which it is hard to sustain collusion when there is an activejim that is likely to exit in the near future numerical analysis is used to compare a collusive to a noncollusive environment only the collusive industry generates price wars also the collusive industry offers both more and higherquality products to consumers albeit often at a higher price the positive effect of collusion on variety and quality more than compensates consumers for the negative effect of collusive prices so that consumer surplus is larger with collusion

physician agency and adoption of generic pharmaceuticals i examine physician agency in health care services in the context of the choice between brand name and generic pharmaceuticals i examine micro panel data from japan where physicians can legally make profits by prescribing and dispensing drugs the results indicate that physicians often fail to internalize patient costs explaining why cheaper generics are infrequently adopted doctors respond to markup differentials between the two versions indicating another agency problem however generics markup advantages are short lived which limits their impact on increasing generic adoption additionally state dependence and heterogeneous doctor preferences affected generics adoption policy makers can target these factors to improve static efficiency

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

dynamic complexity in duopoly games abstract we discuss the occurrence of periodic and chaotic phenomena in infinite horizon duopoly games where firms maximize their discounted sum of profits and use markov perfect equilibrium strategies in the alternating case their corresponding actions are then constrained orbits of a map similar to a cournot t tonnement we show that any behavior is possible for small discount factors and that one obtains the cournot t tonnement as the discount factor goes to zero in the simultaneous case we show by mean of an example that many cournot t tonnements can be viewed as markov perfect equilibria of an infinite horizon game and that one obtains the nash equilibrium of the static game as the discount parameter goes to zero we are thus led to study in detail the dynamical properties of a cournot t tonnement

bridging behavioral and economic theories of decline organizational inertia strategic competition and chronic failure this paper is another plea for bridging behavioral and economic approaches to the study of competition in markets and strategy making by firms the arguments focus on a specific case in point the behavioral theory of organizational decline and the economic modeling of immediate exit the arguments come in three steps first the literature on organizational decline is reviewed by organizing a framework that summarizes arguments from varying economic and organizational perspectives that have for the most part developed independently observations from empirical and theoretical studies are combined in order to investigate the causes conditions courses and consequences of organizational downturn second a theoretical argument is developed that explains voluntary exit and chronic failure by introducing a proxy of organizational inertia in a model of strategic cournot duopoly the key assumptions which have a behavioral flavour that seemingly contradicts orthodox economics are grounded in the theoretical and empirical literatures the results of the model support the claim that pure profit maximizing behavior may be at the expense of organizational survival d aveni 1990 p 135 third by formulating two hypotheses and presenting tentative evidence from the chemical industry the paper hopes to convincingly argue that such integrative models lead to empirical testing of interesting hypotheses a key finding here is that inefficient firms may outlast their efficient rivals cf d aveni 1989a

responding to rivals and complements how market concentration shapes generational product innovation strategy this study examines how competitive market conditions shape the responsiveness with which businesses release generational product innovations gpis following the introduction of gpis by either competitors or complementary firms gpis are substantial technical advances in the performance of products within technology regimes prior studies of innovation timing in the organizational strategy literature emphasize internally driven strategies of gpi although internally driven strategies may predominate when businesses face diffuse competition for their product lines the literature largely overlooks the point that businesses need to be increasingly responsive to external events as market concentration increases this study which examines businesses competing in the u s packaged software industry in the 1990s shows that increasing industry concentration raises the stakes surrounding market positions and leads to greater interdependence of innovation strategies in an industry including interactions both with competitors and with other players in a larger system of complementary products as concentration increases therefore organizations are less driven by historical patterns of innovation and become increasingly responsive to innovations by both types of external actors

learning about new products an empirical study of physicians behavior i introduction an important aspect of economic innovation is the development of new products thus firms often devote large amounts of resources to research and development the pharmaceutical industry in particular is characterized by a high degree of product innovation and significant investments in research and development 1 critical to the adoption of a new pharmaceutical however is the willingness of physicians to prescribe it although clinical trials and advertising convey information about the quality of a new pharmaceutical considerable uncertainty remains not only about its general quality but also about its effect on individual patients 2 because physicians ultimately resolve this uncertainty by prescribing the new drug 3 to their patients namely by experimentation the adoption of a new pharmaceutical is closely related to the experimentation process by which physicians gain information in this paper we focus on the entry of a new antiulcer drug omeprazole in the italian pharmaceutical market in june of 1990 4 our data consist of monthly prescriptions of antiulcer medications by physicians in the rome metropolitan area between june 1990 and december 1992 we develop and estimate a dynamic discrete choice model of physician bayesian learning about the quality of a new drug in our model physicians have initial beliefs about the new drug s efficacy and update them every time that they prescribe the new drug and observe the treatment outcome when choosing which drug to prescribe to a particular patient a forward looking physician considers not only the expected outcome for that patient but also the opportunity to learn about the new drug s quality and use the information on future patients our parameter estimates allow us to disentangle how uncertainty about the new drug s quality intertemporal preferences and prices affect the adoption of the new drug and the corresponding health outcomes a recent literature has explored the role of learning about pharmaceuticals 5 as noted by manchanda et al 2005 in their review of this literature some important aspects of the learning mechanism are the channels through which agents learn prescription detailing marketing meetings and events their preferences toward risk risk averse or risk neutral and whether they are short sighted myopic or forward looking myopic agents maximize their current expected utility while forward looking agents evaluate their current utility as well as the expected future value of the information they might gain through the current prescription 6 the studies also differ in whether they use physician level or aggregate data a central contribution of our paper is the prediction of market demand for the new drug through a parsimonious yet behaviorally rich model using the same physician level data used here coscelli and shum 2004 model the behavior of doctors who learn in a bayesian fashion yet are myopic we in contrast model the forward looking behavior of physicians and reject the null hypothesis that physicians are myopic according to our estimates myopic behavior significantly delays the adoption of the new drug and generates large losses to patients health crawford and shum 2005 use related patient level data and model how forward looking patients learn about their curative and symptomatic matches with respect to alternative medications in their model a patient s learning about a medication is not driven by the fact that the medication is new rather it is driven by her need to learn which medication suits her best hence she learns about her match to each medication not just the new one in our model however learning is driven by the market level uncertainty associated with omeprazole as a new product 7 while it would be of interest to study both doctors and patients learning our doctor level data motivate our focus on physician learning

modeling the dynamics of strategic fit a normative approach to strategic change this study develops and tests a dynamic perspective on strategic fit drawing from contingency and resource based arguments in the strategy and organizational theory literatures we propose a distinctive analytical approach to identify environmental and organizational contingencies that should predict changes in a firm s strategy and the performance implications of such changes we test our model using extensive longitudinal data from over 4000 u s savings and loan institutions during a period when many s ls considered changing strategic direction the findings support our model of dynamic strategic fit specifically we find that 1 the timing direction and magnitude of strategic changes can be logically predicted based on differences in specific environmental forces and organizational resources and 2 organizations that deviated from our model s prediction of dynamic strategic fit i e changed more or changed less than our model prescribed experienced negative performance consequences we conclude by discussing the implications of our approach and findings for future research on strategic fit and strategic change copyright 2000 john wiley sons ltd

endogeneity and simultaneity in competitive pricing and advertising a logit demand analysis in this article we use four data sets to provide a benchmark study of the effects of accounting for endogeneity and simultaneity in estimating marketing mix effects in a logit demand framework we compare the results obtained from accounting for endogeneity only to those from accounting for both endogeneity and simultaneity and in the latter case we allow for more general models of firm behavior to examine the consequences of imposing assumptions about the behavior of firms we find that accounting for both endogeneity and simultaneity not only affects the parameter estimates but also results in efficiency gains that affect the statistical significance of the estimates

strategic flexibility in information technology alliances the influence of transaction cost economics and social exchange theory utilizing a model drawn from both transaction cost economics and social exchange theory we analyze determinants of strategic flexibility in a sample of strategic alliances involved in joint development agreements or joint research pacts findings indicate that in general determinants suggested by transaction cost economics provided flexibility in modification and inflexibility in exit from social exchange theory trust was found to be positively related to both types of flexibility while another component of social exchange theory dependence was found to be negatively related to the strategic flexibility of the alliance results also found that factors suggested by both transaction cost economic theory and social exchange theory were related to the concept of trust economic constraints as suggested by transaction cost economics were positively related to trust between the alliance partners while dependence was negatively related to trust additionally the quality of communication and the existence of shared values were positively related to trust between the exchange partners results provide support for the role of determinants from both transaction cost economics and social exchange theory in the flexibility of strategic alliances

the trap of continual ownership change in international equity joint ventures this article examines how multiple ownership changes unfold in international equity joint venture iejv evolution and how such repeated changes impact short term performance and long term survival by theorizing a new concept the trap of continual change in the iejv context we challenge the adaptive viewpoint assumed in alliance dynamics research we propose that partners sometimes respond to an initial dissatisfaction with the venture result with a dysfunctional repetition of rearranging the ownership control structure this continual change locks the organization into bad choices and sends it into a downward spiral acknowledging the mixed motive nature of inter partner relationships we incorporate cooperative versus competitive dynamics manifested in shared control arrangements we propose that shared ownership control lends stability to the iejv until the initial iejv agreement is renegotiated this stability is a result of the cooperative forces of mutual interdependence and mutual forbearance between the partners however when the power balance breaks down the potential for inter partner conflict increases when the ownership control structure of the iejv is restructured especially multiple times shared control arrangements become increasingly unstable as behavioral cultural and managerial differences are amplified

regulating innovation with uncertain quality information risk and access in medical devices we study the impact of regulating product entry and quality information requirements on an oligopoly equilibrium and consumer welfare product testing can reduce consumer uncertainty but also increase entry costs and delay entry using variation between eu and us medical device regulations we document patterns consistent with valuable learning from more stringent us requirements to derive welfare implications we pair the data with a model of supply demand and testing regulation us policy is indistinguishable from the policy that maximizes total surplus in our estimated model while the european union could benefit from more testing post market surveillance could further increase surplus

multinationals and anti sweatshop activism during the 1990s anti sweatshop activists campaigned to improve conditions for workers in developing countries this paper analyzes the impact of antisweatshop campaigns in indonesia on wages and employment identification is based on comparing the wage growth of workers in foreign owned and exporting firms in targeted regions or sectors before and after the initiation of antisweatshop campaigns we find the campaigns led to large real wage increases for targeted enterprises there were some costs in terms of reduced investment falling profits and increased probability of closure for smaller plants but we fail to find significant effects on employment jel f23 j31 j81 l67 o14 o15

perverse reverse price competition average wholesale prices and medicaid pharmaceutical spending abstract generic drugs comprise an increasing share of total prescriptions dispensed in the u s rising from nearly 50 in 1999 to 75 in 2009 the generic drug market has typically been viewed at the wholesale level as a competitive market with price approaching marginal costs however the large presence of third party payers as final purchasers may distort prices at the retail level relative to what a standard model of price competition would predict in this paper we investigate how generic drug producers compete in the presence of the procurement rules of the medicaid program medicaid reimbursement to pharmacies like that of other payers is based on a benchmark price called the average wholesale price awp the awp is reported by generic producers themselves and until recently has been subject to essentially no independent verification as a result generic producers have had an incentive to compete for pharmacy market share by reporting awps that exceed actual average wholesale prices as this spread leads to larger pharmacy profits in 2000 after a federal government audit of actual wholesale prices of generic products states were advised to reduce medicaid reimbursement by as much as 95 for about 400 generic and off patent drug products we use variation induced by the timing of this policy along with its differential impact on drug products medicaid reimbursement to estimate the impact of this exogenous price change on the market share of targeted products our findings indicate that pharmacies did respond to the perverse incentives of the medicaid program by dispensing products with the highest awps overall the medicaid market share fell by about 45 for targeted drug products as a result of the policy

firm behaviour and innovative performance an empirical exploration of the selection adaptation debate innovation is a complex trade off between routinisation and change between reliability and accountability of firms and timely adaptation this innovator s dilemma confronts innovation theory with the question how to align routinisation with innovation induced organisational change and consistent performance obviously it is a complex issue dominant innovation theory neglects this subject due to its pro innovation bias while evolutionary organisation and innovation theory give opposite perspectives on this problem the adaptation perspective considers pro active behaviour as the best condition for innovative performance whereas the selection perspective advances inert firm behaviour as the best alternative to achieve successful innovations our research question focuses on the explanatory value of either the selection or the adaptation perspective for the innovative performance of industrial firms our empirical findings confirm the adaptation perspective and reject the selection perspective comparatively firm behaviour involving the highest risks and uncertainties e g high environmental dynamics and high levels of adaptive activity contributes most significant to the explanation of innovative performance inert risk averse behaviour conversely does not improve or even impedes innovative performance compared with other types of firm behaviour

structuring a theory of moral sentiments institutional and organizational coevolution in the early thrift industry the authors investigate the coevolution of organizations and institu tions they study how institutional definitions rules and expectations unfold in tandem with the organizational structures and processes that embody those institutions the research site is the early thrift industry changes in thrifts technical environment the rise of a transient and heterogeneous population and institutional environment the rise of progressivism propelled this coevolutionary process the coevolution of thrift organizations and institutions proceeded primarily through selection adaptation was constrained by both institutional factors it was difficult to adopt a novel institutional logic and technical factors early thrifts were generally small so entry and exit were easy

out of the frying pan why small business managers introduce high risk products abstract some managers in small firms who are disappointed with their firm s current performance will introduce new products to improve the situation although untested in a small business context prospect theory suggests that managers who are less satisfied may be more likely to introduce products with riskier characteristics the current study confirmed this finding that managers who were less satisfied introduced products into less familiar markets and required more resources the study also provided tentative evidence that these characteristics may decrease the product s economic performance and the manager s subsequent satisfaction with the business suggesting that a dangerous downward spiral may occur

convergence to symmetry in dynamic strategic models of r d the undiscounted case abstract will r d increase or decrease the asymmetry between firms over time we examine this issue in the context of a dynamic alternate move duopoly model of non cooperative r d the asymmetry we consider is with respect to the initial stocks of technological knowledge which provides one firm a greater potential for current and future profits in the product market utilizing a value loss process constructed from the optimality equation of dynamic programming we show that for the undiscounted case the asymmetry between the firms disappears over time we obtain this convergence to symmetry result by imparting a temporal character to r d through the notion that r d investment cannot be changed instantaneously by allowing research externalities complementarity or substitutability between own and appropriated r d and either increasing decreasing or constant returns to scale in the production of technical knowledge from own and rival r d

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

regulation of pharmaceutical prices evidence from a reference price reform in denmark reference price systems for prescription drugs constitute widely adopted cost containment tools under these regimes patients co pay a fraction of the difference between a drug s pharmacy retail price and a reference price that is set by the government reference prices are either externally based on drug prices in other countries or internally based on domestic drug prices determined we study the effects of a change from external to internal reference pricing in denmark in 2005 we find that the reform led to substantial reductions in retail prices reference prices and patient co payments as well as to sizable decreases in overall producer revenues and health care expenditures the reform induced consumers to substitute away from branded drugs for which we estimate strong preferences the increase in consumer welfare due to the reform therefore depends on whether or not we take perceived quality differences into account in its calculation

new blood as an elixir of youth effects of human capital tenure on the explorative capability of aging firms the relationship between firm age and innovation has been an enduring topic of interest we contribute to this research by studying how the effect of firm age on the quality of explorative and exploitative innovations is affected by the firm specific and industry tenure of the talent resources employees that the firm utilizes we start with the baseline predictions that firm age is related to the development of better exploitative innovations and worse explorative innovations however the tenure of employees intervenes in these relationships by way of bringing in new knowledge mental models and beliefs we predict that longer firm specific and industry tenure of employees enhances the positive effect of firm age on the quality of exploitative innovations while amplifying the negative effect of firm age on the quality of explorative innovations in addition for both the baseline and the moderating effect we also formulate a prediction comparing the quality of explorative innovations with those of

country and organizational level adaptation to foreign workplace ideologies a comparative study of distributive justice values in china russia and the united states drawing from concepts of cultural distance and cultural propensity to change we predict the convergence divergence or crossvergence of distributive justice values in china and russia as compared with us managers using institutional theory we predict responses by organizational type joint ventures foreign owned vs state owned enterprises soes lastly we develop predictions based on the interaction of culture and organizational type results indicate divergence in china regardless of organizational type in contrast differences by organizational type were observed among russian managers with convergence among managers in joint ventures but continuing divergence among managers in soes implications for theory are discussed

inside the hybrid iron cage political origins of hybridization this paper examines how social movement type political interactions between conflicting parties within an organization influence the adoption of a hybrid practice we argue that a hybrid practice is likely to be adopted when power balance between challengers and incumbents is achieved to shed light on conditions for organizational settlement based on such power balance we focus on three factors structures actors and processes of social movement type political interactions within organizations by studying changes in the presidential selection systems of korean universities between 1988 and 2006 this paper illustrates how organizational settlement resulted in the adoption of a hybrid system by combining elements of two previous competing presidential selection systems appointment and direct voting systems the general implications for the understanding of hybridization organizational settlement and organizational heterogeneity are discussed

strategic investment and conjectural variations abstract this paper analyzes investment decisions under the alternative assumptions of competitive collusive open loop non cooperative and feedback non cooperative behavior steady state capital stocks prices and outputs are obtained and compared the paper shows that one of the linear feedback equilibrium decision rule coefficients is a dynamic version of a contemporaneous conjectural variation the same decision rule coefficients are shown to imply a particular value for the contemporaneous conjecture the implied conjecture embodies subgame perfection and approaches the competitive value as the number of firms in the industry increases

decision making under uncertainty capturing dynamic brand choice processes in turbulent consumer goods markets we construct two models of the behavior of consumers in an environment where there is uncertainty about brand attributes in our models both usage experience and advertising exposure give consumers noisy signals about brand attributes consumers use these signals to update their expectations of brand attributes in a bayesian manner the two models are 1 a dynamic model with immediate utility maximization and 2 a dynamic forward looking model in which consumers maximize the expected present value of utility over a planning horizon given this theoretical framework we derive from the bayesian learning framework how brand choice probabilities depend on past usage experience and advertising exposures we then form likelihood functions for the models and estimate them on nielsen scanner data for detergent we find that the functional forms for experience and advertising effects that we derive from the bayesian learning framework fit the data very well relative to flexible ad hoc functional forms such as exponential smoothing and also perform better at out of sample prediction another finding is that in the context of consumer learning of product attributes although the forward looking model fits the data statistically better at conventional significance levels both models produce similar parameter estimates and policy implications our estimates indicate that consumers are risk averse with respect to variation in brand attributes which discourages them from buying unfamiliar brands using the estimated behavioral models we perform various scenario evaluations to find how changes in marketing strategy affect brand choice both in the short and long run a key finding obtained from the policy experiments is that advertising intensity has only weak short run effects but a strong cumulative effect in the long run the substantive content of the paper is potentially of interest to academics in marketing economics and decision sciences as well as product managers marketing research managers and analysts interested in studying the effectiveness of marketing mix strategies our paper will be of particular interest to those interested in the long run effects of advertising note that our estimation strategy requires us to specify explicit behavioral models of consumer choice behavior derive the implied relationships among choice probabilities past purchases and marketing mix variables and then estimate the behavioral parameters of each model such an estimation strategy is referred to as structural estimation and econometric models that are based explicitly on the consumer s maximization problem and whose parameters are parameters of the consumers utility functions or of their constraints are referred to as structural models a key benefit of the structural approach is its potential usefulness for policy evaluation the parameters of structural models are invariant to policy that is they do not change due to a change in the policy in contrast the parameters of reduced form brand choice models are in general functions of marketing strategy variables e g consumer response to price may depend on pricing policy as a result the predictions of reduced form models for the outcomes of policy experiments may be unreliable because in making the prediction one must assume that the model parameters are unaffected by the policy change since the agents in our models choose among many alternative brands their choice probabilities take the form of higher order integrals we employ monte carlo methods to approximate these integrals and estimate our models using simulated maximum likelihood estimation of the dynamic forward looking model also requires that a dynamic programming problem be solved in order to form the likelihood function for this we use a new approximation method based on simulation and interpolation techniques these estimation techniques may be of interest to researchers and policy makers in many fields where dynamic choice among discrete alternatives is important such as marketing decision sciences labor and health economics and industrial organization

on measuring the effects of fiscal policy in recessions we do not have a good measure of the effects of fiscal policy in a recession because the methods that we use to estimate the effects of fiscal policy both those using the observed outcomes following different policies in aggregate data and those studying counterfactuals in fitted model economies almost entirely ignore the state of the economy and estimate the government multiplier which is presumably a weighted average of the one we care about the multiplier in a recession and one we care less about the multiplier in an expansion notable exceptions to this general claim sug gest this difference is potentially large our lack of knowledge stems significantly from the focus on linear dynamics vector autoregressions and linearized or close to linear dynamic stochastic general equilibrium dsge models our lack of knowledge also reflects a lack of data deep recessions are few and nonlinearities hard to measure the lack of statistical power in the estimation of nonlinear models using aggregate data can be addressed by exploiting estimates of partial equilibrium responses in disaggregated data microeconomic estimates of the partial equilibrium causal effects of a policy can discipline the causal channels inherent in any dsge model of the general equilibrium effects of policy microeconomic studies can also provide measures of the dependence of the effects of a policy on the states of different agents which is a key component of the dependence of the general equilibrium effects of fiscal policy on the state of the

adapting to radical change strategy and environment in piece rate adoption during china s transition adaptation to radical change is central to research in organization theory and some of the most dramatic examples of environmental change have occurred recently in transition economies such as china i take advantage of change during china s economic reform to study the relative importance of organizational and environmental factors in producing innovative managerial response i find that strategic choice predicted innovation in the early stages of reform but environmental factors increased in salience over time intrafirm support communist party connections and a market orientation produced innovation early in reform simple imitation of others was also salient in early years as reform progressed managers increasingly imitated other profitable firms and drew on their own experience my results inform an understanding of both the process by which innovation occurs and firm behavior in transition economies

move to the beat rhythms of change and firm performance this study examines how different rhythms of change relate to firm performance an explorative analysis of 67 european insurance companies between 1995 and 2004 reveals that corporate strategic changes occur in four distinct rhythms which are classified as either regular or irregular focused punctuated and temporarily switching subsequent quantitative analysis shows that companies that change regularly outperform those that change irregularly this finding prevails under different internal and external contingencies under different change characteristics and over time periods we also find that the rhythm and frequency of change have distinct performance effects our findings contribute to research on the change stability paradox by showing that a regular and sequential balance between change and stability is associated with long term success

the effects of banning advertising in junk food markets we develop a structural model to analyze the eects of banning advertising on market equilibria and welfare in junk food markets we consider the impact on demand and prices and show how to quantify welfare eects when advertising might lead consumers to take decisions that are inconsistent with their underlying preferences we use transaction level data on the potato chips market and nd that banning advertising leads to a direct reduction in demand but also toughens price competition leading to lower prices and increased demand welfare increases as consumers benet from no longer making distorted

experimentation and learning in a differentiated products duopoly abstract this paper explores price setting behavior in the context of a duopoly in which firms are uncertain about the degree of product differentiation firms learn from the difference in their realized demands in light of the price differential the informativeness of this market experiment is shown to be increasing in size of the price differential in markets with highly substitutable products price dispersion is enhanced as firms adjust their prices so as to generate more information in markets with highly differentiated products firms compress their prices as they prefer to reveal less about the extent of product differentiation journal of economic literature classification numbers d43 d83 l13

a dynamic analysis of the market for wide bodied commercial aircraft this paper uses an empirical dynamic oligopoly model of the commercial aircraft industry to analyse industry pricing industry performance and optimal industry policy a novel feature of the model with respect to the previous literature is that entry exit prices and quantities are endogenously determined in markov perfect equilibrium mpe we find that many unusual aspects of the aircraft data such as high concentration and persistent pricing below static marginal cost are explained by this model we also find that the unconstrained mpe is quite efficient from a social perspective providing only 10 less welfare on average than a social planner would obtain finally we provide simulation evidence that an anti trust policy in the form of a concentration restriction would be welfare reducing

learning from experience simply there is substantial academic interest in modeling consumer experiential learning however approximately optimal solutions to forward looking experiential learning problems are complex limiting their behavioral plausibility and empirical feasibility we propose that consumers use cognitively simple heuristic strategies we explore one viable heuristic index strategies and demonstrate that they are intuitive tractable and plausible index strategies are much simpler for consumers to use but provide close to optimal utility they also avoid exponential growth in computational complexity enabling researchers to study learning models in more complex situations well defined index strategies depend on a structural property called indexability we prove the indexability of a canonical forward looking experiential learning model in which consumers learn brand quality while facing random utility shocks following an index strategy consumers develop an index for each brand separately and choose the brand with the highest index using synthetic data we demonstrate that an index strategy achieves nearly optimal utility at substantially lower computational costs using iri data for diapers we find that an index strategy performs as well as an approximately optimal solution and better than myopic learning we extend the analysis to incorporate risk aversion other cognitively simple heuristics heterogeneous foresight and an alternative specification of brands

market diffusion with two sided learning we analyze the diffusion of a new product of uncertain value in a duopolistic market both sides of the market buyers and sellers learn the true value of the new product from experiments with it buyers have heterogeneous preferences over the products and sellers compete in prices the pricing policies and market shares in the unique markov perfect equilibrium are obtained explicitly the dynamics of the equilibrium market shares display excessive sales of the new product relative to the social optimum in early stages and too low sales later on the diffusion path of a successful product is s shaped

how organizational resources affect strategic change and performance in turbulent environments theory and evidence this study examines how historical resource endowments and competencies affect strategic change and its outcomes amid environmental turbulence drawing from both behavioral and economics based literatures we develop four distinct perspectives regarding the likely effect of resources on strategic change these four perspectives offer alternative predictions about how and why resource endowments should affect the likelihood or magnitude of strategic change and how and why they should moderate the relation between strategic change and performance we examine the predictive power of these four alternative arguments using extensive longitudinal data from a single industry context characterized both by substantial resource heterogeneity and environmental turbulence results indicate that organizations possessing greater stocks of historically valuable resources were much less likely to engage in adaptive strategic change but also that this resource driven disinclination towards change tended to have a benign or even beneficial effect on performance we discuss the implications of our theory and findings for the strategic change literature and also for the literature on the resource based view of the firm

patents as options some estimates of the value of holding european patent stocks in many countries holders of patents must pay an annual renewal fee in order to keep their patents in force this paper uses data on the proportion of patents renewed and the renewal fees faced by post world war ii cohorts of patents in france the united kingdom and germany in conjunction with a model of patent holders renewal decisions to estimate the returns earned from holding patents in these countries since patents are often applied for at a nearly stage in the innovation process the model allows agents to be uncertain about the sequence of returns that will be earned if the patent is kept inforce formally then the paper presents and solves a discrete choice optimal stochastic control model derives the implications of the model on aggregate behaviour and then estimates the parameters of the model from aggregate data the estimates enable a detailed description of the evolution of the distribution of returns earned from holding patents over their life spans and calculations of both the annual returns earned from holding the patents still in force or the patent stocks in the alternative countries and the distribution of the discounted value of returns earned from holding the patents in a cohort this abstract was borrowed from another version of this item

start up sustainability an insurmountable cost or a life giving investment abstract an outstanding question in the entrepreneurship literature reigns given recent emphases on sustainable business practices and corporate social responsibility if small start ups are generally stretched for time and resources does it enhance their chances for survival and success to be sustainable and socially responsible new firms can aid in rectifying pressing environmental and social issues by being more sustainable while many entrepreneurs like a sustainable business model and or mission investment may not follow so willingly this paper examines a sample of 300 start ups across thirty cities around the world to consider whether sustainability is rewarded by investors investors signal confidence in start ups when they infuse life extending investments into them this analysis also considers whether a more sustainable national context affects investor confidence and whether a sustainable firm within a sustainable national context gains more investor attention and investment results show that investors avoid sustainable firms particularly those that are environmentally sustainable moreover investors enjoy national contexts that are socially responsible but pay no attention to those that are environmentally conscious in addition firms that are sustainable in a sustainable national context are not better off for attracting investment insights for policy are that mainstream investors are attracted by national social policies but these investors are unlikely to be the main force behind sustainable venture growth under today s conditions

entry and vertical differentiation this paper analyzes the entry of new products into vertically differentiated markets where an entrant and an incumbent compete in quantities the value of the new product is initially uncertain and new information is generated through purchases in the market we derive the unique markov perfect equilibrium of the infinite horizon game under the strong long run average payoff criterion the qualitative features of the optimal entry strategy are shown to depend exclusively on the relative ranking of established and new products based on current beliefs superior products are launched relatively slowly and at high initial prices whereas substitutes for existing products are launched aggressively at low initial prices the robustness of these results with respect to different model specifications is discussed

frequent incremental change organizational size and mortality in high technology competition while radical technological change is often characterized as hazardous particularly to incumbents incremental technological change has appeared to be immune from such risks little attention has been given to the possibility that under some circumstances incremental technological change can be quite risky this article argues that there may be tradeoffs to high rates of incremental technological change the costs are of two kinds the organizational disruptions associated with frequent technological change and overestimating the advantages and receptiveness of the technological improvement we argue that larger firms are better equipped than smaller firms to cope with these costs and will reap greater benefits from incremental changes using data on the population of worldwide floppy disk drive manufacturers we find that frequent incremental technical changes decrease organizational mortality for large firms but increase it for smaller firms we also find that large firms that frequently introduce incremental technological improvements are more potent competitors this study helps us understand how frequent incremental change affects mortality as organizations grow advice to managers to engage in continuous incremental innovation can therefore be misguided because unless firms are large they may incur costs that are so great that the firm actually fails by innovating frequently copyright 2010 the author 2009 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

sweatshop regulation tradeoffs and welfare judgements the standard economic and ethical case in defense of sweatshops employs the standard of the welfare of their workers and potential workers to argue that sweatshop regulations harm the very people they intend to help scholars have recently contended that once the benefits and costs are balanced regulations do in fact raise worker welfare this paper describes the short and long run tradeoffs associated with sweatshop regulation and then examines how reasonable constructions of measures of worker welfare would evaluate these tradeoffs finding that the standard economic and ethical case against sweatshop regulations is well supported
