competition and social influence the diffusion of the sixth generation processor in the global computer industry1 when is a social actor most strongly influenced by its peers this article addresses this question by clarifying when computer firms were most strongly affected by the choices of their structurally equivalent rivals to adopt a well known technology intel s sixth generation processor the core hypothesis is that the effect of adoptions by structurally equivalent firms increases with the competitive pressure that a focal firm faces in its market position the results show that a chosen firm is most strongly influenced by comparable others when it faces scale based competition and is diversified the implications of this study are twofold a social actor s sensitivity to the conduct of others may depend not only on its place in a hierarchy but also on the nature of its ties to an external audience and a contingent theory of social influence may be necessary to characterize diffusion processes correctly particularly when external and time varying nonnetwork factors have significant effects

consumer research with big data applications from the food demand survey foods in three separate studies based on data from the food demand survey foods which has been conducted monthly for over three years this paper explores heterogeneity in preference across consumers in traditional demand systems heterogeneity in preferences over time in choice experiments and the tail of the distribution for a particular food consumption pattern vegetarianism results show that elasticities of demand for food at home and food away from home vary widely across different groups of consumers defined by a priori cluster analysis based on demographic and attitudinal variables results from a choice experiment are found to depend on when the experiment was conducted and on the market prices prevailing at the time of the survey given the large sample of consumers observed over time there is sufficient data to demographically characterize a small portion of the population vegetarians using traditional logit models and a machine learning method a classifications tree

gender sorting and the glass ceiling in high tech firms with few exceptions studies have conceived of the glass ceiling as reflecting internal promotion biases in this article the authors argue that glass ceiling patterns can also be the result of external recruitment and hiring processes using data on people applying by means of the internet for jobs at 441 small and medium sized high tech firms they find evidence that the glass ceiling is produced by both internal and external hiring processes on the supply side females are sorted into lower level job queues than males on the demand side screening biases against women also are evident but a series of what if simulations suggest that demand side screening processes play a comparatively minor role in producing the glass ceiling pattern these results suggest that bias remediation policies designed to equalize gender differences in hiring chances are likely to be less effective than recruitment and outreach policies designed to improve gender disparities in candidate pools

structural workshop paper discrete choice models of consumer demand in marketing marketing researchers have used models of consumer demand to forecast future sales to describe and test theories of behavior and to measure the response to marketing interventions the basic framework typically starts from microfoundations of expected utility theory to obtain an econometric system that describes consumers choices over available options and to thus characterize product demand the basic framework has been augmented significantly to account for quantity choices to accommodate purchases of several products on a single purchase occasion multiple discreteness and multicategory purchases and to allow for asymmetric switching between brands across different price tiers these extensions have enabled researchers to bring the analysis to bear on several related marketing phenomena of interest this paper has three main objectives the first objective is to articulate the main goals of demand analysis forecasting measurement and testing and to highlight several considerations associated with these goals our second objective is to describe the main building blocks of individual level demand models we discuss approaches built on direct and indirect utility specifications of demand systems and we review extensions that have appeared in the marketing literature the third objective is to explore a few emerging directions in demand analysis including considering demand side dynamics combining purchase data with primary information and using semiparametric and nonparametric approaches we hope researchers new to this literature will take away a broader perspective on these models and see the potential for new directions in future research

am i getting a good deal reference dependentdecision making when the reference price is uncertain models of consumer decision making commonly incorporate reference dependent preferences in these models the reference point is typically assumed to be known by the consumer however research on price recall and the reference formation process reveals that the reference price is often uncertain at the time of purchase reference price uncertainty creates ambiguity for the consumer about whether they are getting a good or bad deal this paper develops a model of consumer choice in the presence of reference dependent preferences when the reference price is uncertain data from two empirical studies that vary the product category and order of the elicitation of reference prices show that the new model generally outperforms conventional discrete choice models that either ignore reference prices or treat reference prices as certain the new model provides insights into the effect of reducing reference price uncertainty on consumer choice and reveals that high uncertainty smoothes the kink in the demand curve that is present in traditional reference price demand models

quality quantity and spatial variation of price this paper develops and implements a method for estimating price elasticities of demand using cross sectional household survey data geographically clustered households report unit values which when corrected for quality effects and for measurement error indicate the underlying spatial variation in prices and can be matched to variation in demand patterns a simple model of quality choice is proposed while the correction for measurement error exploits the clustered design of such surveys data from a 1979 household survey from the ivory coast are used to estimate price elasticities for beef meat fish cereals and starches copyright 1988 by american economic association

looking for loss aversion in scanner panel data the confounding effect of price response heterogeneity recent work in marketing has drawn on behavioral decision theory to advance the notion that consumers evaluate attributes and therefore choice alternatives not only in absolute terms but asdeviations from a reference point the theory has important substantive and practical implications for the timing and execution of price promotions and other marketing activities choice modelers using scanner panel data have tested for the presence of these reference effects in consumer response to an attribute such as price in applications of the theory of reference dependent choice tversky and kahneman 1991 some modelers report empirical evidence of loss aversion when a consumer encounters a price above his or her established reference point a loss the response is greater than for a price below the reference point a gain researchers have gone so far as to suggest that evidence for the so called reference effect make it an empirical generalization in marketing e g kalyanaram and winer 1995 meyer and johnson 1995 it is our contention that the measurement of loss aversion in empirical applications of the reference dependent choice model is confounded by the presence of unaccounted for heterogeneity in consumer price responsiveness our reasoning is that the kinked price response curve implied by loss aversion is confounded with the slopes of the response curves across segments that are differentially responsive to price a more price responsive consumer with a steeper response function tends to have a lower price level as a reference point this consumer faces a larger proportion of prices above his reference point thus the response curve is steeperin the domain of losses similarly the less price responsive consumer sees a greater proportion of prices below his reference point so the response curve is less steep within the domain of gains as a result any cross sectional estimate of loss aversion that does not take this into account will be biased upward researchers who do not control for heterogeneity in price responsiveness may arrive at incorrect substantive conclusions about the phenomenon it is interesting to note that in this instance failure to control for heterogeneity induces a bias infavor of finding an effect rather than the more typical case of attenuation of the effect toward zero we first test our assertion regarding the referencedependent model using scanner panel data on refrigerated orange juice and subsequently extend this analysis to 11 additional product categories in all cases we find as predicted that accounting for price response heterogeneity leads to lower and frequently nonsignificant estimates of loss aversion we do however find some categories in which the effect does not disappear altogether we also estimate loss aversion using a sticker shock model of brand choice in which the reference prices arebrand specific in line with the results of the majority of prior literature we find smaller and insignificant estimates of loss aversion in this model we show that this is because in the sticker shock model there is no apparent correlation between the price responsiveness of the consumer and the representation of reference effects as losses or gains our findings strongly suggest that loss aversion may not in fact be a universal phenomenon at least in the context of frequently purchased grocery products

internal labor markets too many theories too few facts that firms employ internal labor markets in which wages and careers are partly shielded from the vagaries of external labor markets seems well accepted yet peter doeringer and michael piore s 1985 seminal work on internal labor markets has had a rather limited impact on the economics profession in contrast to textbooks on human resource management which have adopted their paradigm wholeheartedly labor economics texts tend to pay only cursory attention to internal labor markets the competitive model in which wages reflect an individual s marginal product remains the paradigm of choice there are many reasons for this lackluster reception including intellectual convenience a more acceptable excuse is that while doeringer and piore s study which was based on interviews with 75 companies identified several key regularities ports of entry career ladders etc that have come to shape our perception of internal labor markets the book never presented a theory to explain these findings with the advent of information economics and contract theory models of internal labor markets or at least selected features of these markets have begun to emerge the objective of these theories is to show that internal labor market outcomes can be construed as second best solutions to contracting problems under incomplete information for instance tournament theory edward lazear and sherwin rosen 1981 sees the attachment of wages to jobs as part of an efficient incentive scheme michael waldman 1984 explains the same phenomenon as an insurance arrangement against variations in individual productivity seniority rules in promotion and wagesetting can be understood as responses to problems of collusion or influence activities paul milgrom and john roberts 1988 the list could be extended at this point there is hardly any feature of internal labor markets that cannot be given some logical explanation using the right combination of uncertainty asymmetric information and opportunism doeringer and piore 1985 in the preface to the second printing of their book take exception with this line of theoretical research they believe that internal labor markets are inherently a social group phenomenon and that something fundamental is missed by pursuing individualistic models be that as it may we think there is another more serious problem with the direction that this research has taken too much of it relies on the old empirical stereotype the original study was done 25 years ago and focused almost exclusively on blue collar male unionized manufacturing workers one might rightly wonder how relevant these findings are in today s environment and whether they extend to white collar work as most discussions seem to assume before proceeding with the theory it is prudent to ask do we have the facts right in this paper we report on two recent case studies of individual firms that use personnel records to analyze wage and career paths of managerial workers lazear 1992 and baker et al 1994a b 1 person

an economic approach to influence activities in organizations members of organizations spend considerable time effort and ingenuity attempting to influence decision makers such influence activities may bring benefits to the organization but they also involve real costs this essay offers an economic rationale for such influence activity as representing rational self interested behavior in the presence of informational asymmetries and an analysis of how the design of the organization s structure and policies should respond to the incentives for attempting influence it is posited that information valuable for the organization s decision making is directly available only to members of the organization who have some personal stake in the decisions these individuals may then have an incentive to try to manipulate the information they develop and provide in order to influence the resulting decisions to their benefits this can be costly both in degrading the quality of decision making and in diverting the attention and effort of the organization s members from more productive activities the organization has three different methods it can employ to discourage excessive influence activities and to encourage more directly productive uses of time and effort it can limit access to decision makers and participation in decision making it can alter its decision making criteria to favor those performing well in productive activities and it can provide direct financial incentives to encourage the desired allocation of effort it is shown that an efficiently designed organization will use such financial incentives only as a last resort instead it will always first alter its decision participation policies and decisionmaking criteria

market structure uncertainty and intrafirm diffusion the case of optical scanners in grocery stores this study uses monthly data on the adoption of optical scanners by sixty three grocery chains in thirty two large u s cities to identify the determinants of the rate of intrafirm diffusion the methodology involves a two stage approach that relates market environment characteristics to the estimated rate of intrafirm diffusion the results indicate that firms with larger market shares adopt a new innovation scanners more quickly initially but diffuse the innovation through their stores more slowly than firms with smaller market shares in addition firms that lag competitors in the initial adoption of scanners tend to diffuse the innovation more quickly copyright 1992 by mit press

institutional labor economics the new personnel economics and internal labor markets a reconsideration the author illustrates the utility of institutional labor economics and makes a case for a reconsideration of it two recent developments motivate this effort the rise of new personnel economics npe as a significant subfield of labor economics and the substantial shifts in work organization that have taken place since the 1990s understanding how and why firms have reorganized work opens the door for a renewed interest in institutional approaches the author explains that the rules of institutional labor markets ilms emerge from the competition between organizational interest groups unions personnel professionals and the government and competing views of firms objectives resulting in the rise of ilms the slow diffusion of high performance work systems strategies used to obtain a high level of commitment from workers the use of contingent employees and the spread of new promotion rules in response to equal employment opportunity pressures as such the role of power and influence in establishing work rules is of central concern though more conventional npe considerations also remain important

predicting the effects of sugar sweetened beverage taxes on food and beverage demand in a large demand system a censored exact affine stone index incomplete demand system is estimated for 23 packaged foods and beverages and a numeraire good instrumental variables are used to control for endogenous prices a half cent per ounce increase in sugar sweetened beverage prices is predicted to reduce total calories from the 23 foods and beverages but increase sodium and fat intakes as a result of product substitution the predicted decline in calories is larger for low income households than for high income households although welfare loss is also higher for low income households neglecting price endogeneity or estimating a conditional demand model significantly overestimates the calorie reduction

bank commercial loan markets and the role of market structure evidence from surveys of commercial lending abstract this paper seeks to test two tenets that underlie the current practice of antitrust analysis in banking the first is the view that bank commercial loan markets are local in nature and the second is the view that banks in more concentrated markets are more likely to engage in some form of noncompetitive behavior tests of both of these tenets are conducted using an extensive set of loan specific survey information not previously employed to address these issues results consistent with the existence of local banking markets and the dominance of competitive differences as an explanation for observed differences in loan rates are found

household welfare and co2 emission impacts of energy and carbon taxes in mexico abstract we analyse the effects of environmental taxes on welfare and carbon emissions at the household level for the case of mexico the integrated welfare environmental analysis which is based on a censored energy consumer demand system extends previous work in two ways first the estimation of a full matrix of substitution elasticities allows us to test the necessity of incorporating second order effects into the welfare analysis second the substitution elasticities derived from the demand system are used to estimate the shortrun co2 emission reduction potential we find that first order approximations of welfare effects provide reasonable estimates particularly for carbon taxes analog to evidence in other low and middle income countries the taxation of all energy items is found to be regressive with the exception of motor fuels the analysis of the emission implications of different tax scenarios indicates that short run emission reductions at the household level can be substantial though the effects depend on how revenue is recycled this effectiveness combined with moderate and manageable adverse distributional impacts renders the carbon tax a preferred mitigation instrument considering the large effect of food price increases on poverty and the limited additional emission saving potential the inclusion of ch4 and n2o in a carbon tax regime is not advisable

incorporating reference price effects into a theory of consumer choice although there has been a good deal of research on incorporating the effects of reference price formation into empirical models of consumer buying behavior little formal theoretical work had been undertaken to date this paper incorporates reference price effects into the traditional economic theory of consumer choice and examines the effects of reference price formation on the results of the traditional theory its marketing implications and the implications for empirical models which examine the effects of reference price formation on actual consumer behavior several implications of the theoretical model are empirically tested using weekly retail egg sales data from southern california this analysis indicates that reference price formation does have significant effects on consumer behavior furthermore these effects are asymmetric with consumers two and a half times more responsive to egg price increases that are in excess of the reference price than they are to comparable egg price decreases

foreign ownership and technology adoption evidence from indian firms abstract firms in developing countries rely on foreign technology purchases to improve their technology we use a theoretical framework developed by katz and shapiro to examine the ongoing technology adoption behavior of foreign owned and domestic firms using firm level data on indian firms from 1989 to 1993 we test this theoretical model we find that foreign ownership firm size and market structure are among the variables that impact a firm s probability of adopting new technology we also find that the 1991 liberalization of technology transfer policies in india appears to have had a larger impact on foreign owned firms than domestic firms

in search of excellence fads success stories and adaptive emulation1 the faddishness of the business community is often noted and lamented but not well understood by standard models of innovation and diffusion we combine arguments about organizational cognition and institutional mimicry to develop a model of adaptive emulation where firms respond to perceived failure by imitating their most successful peers computational experiments show that this process generates empirically plausible cascades of adoption even if innovations are entirely worthless faddish cycles are most robust across alternative treatments of managerial decision making where innovations have modest positive effects on outcomes these results have broad implications for the faddishness of a business community increasingly marked by media driven accounts of success and for the properties of organizational practices that are hot one day and cold the next

the success of a policy model irrigation management transfer in mexico abstract the mexican policy of irrigation management transfer has been widely propagated as a success and has become a model for other countries seeking to improve the performance of their irrigation systems while also cutting public expenditures this article analyses the process of policy making that has generated the policy model and follows the practices means and events through which it has achieved increasing transnational circulation popularity and support the main argument of this article is that the success of a policy model is only a success within the cultural and ideological understandings of a policy network and given the means practices and events that generate and disseminate it this particular case further suggests that success in policy making rather than being based on straightforward evidence of improved management performance is often part of a cultural performance

refraining from imitation professional resistance and limited diffusion in a financial market why do some practices not spread although this is an important question for both diffusion theorists and those interested in institutional change we know surprisingly little about the limitations on diffusion because most diffusion studies sample on successful diffusion i address the question of why some practices fail to spread by introducing the concept of a deviance discount a deviance discount is a systematic downgrading of the observed adoption performance of controversial practices which limits the contagion of such practices i test and find qualitative and quantitative support for my thesis in the product introduction behavior of swedish mutual fund firms my findings hold implications for diffusion theory and theories of endogenous institutional change

an evaluation of federal policy instruments to stimulate basic research in industry a model of the resource allocation behavior of a group of firms demonstrates that unaided industry allocation to basic inappropriable research is suboptimal furthermore provision of seed money is generally counterproductive while the provision of a matching subsidy is not very cost efficient in increasing the allocation innovative policy alternatives are proposed

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

empirical generalizations from reference price research considerable theoretical justification for consumers use of psychological reference points exists from the research literature from a managerial perspective one of the most important applications of this concept is reference price an internal standard against which observed prices are compared in this paper we propose three empirical generalizations that are well supported in the marketing literature first there is ample evidence that consumers use reference prices in making brand choices second the empirical results on reference pricing also support the generalization that consumers rely on past prices as part of the reference price formation process third consistent with other research on loss aversion consumers have been found to be more sensitive to losses i e observed prices higher than reference prices than gains we also propose topics for further research on reference prices

the intra firm diffusion of new process technologies the study of intra firm diffusion has largely been neglected and the limited extant literature overwhelmingly relies upon uncertainty reduction via information spreading or epidemic learning as the main driver in this paper an alternative approach is taken whereby the intra firm diffusion of new process technologies reflects the profitability of new technology adoption as proxied by firm characteristics the approach is tested using data relating to the diffusion of computer numerically controlled machine tools within firms in the uk engineering and metalworking sectors the empirical analysis does not reject the hypothesis that profitability considerations are important with a number of firm characteristics being isolated as of special relevance including firm size and the use of complementary technologies and managerial techniques however there is little support for the traditional epidemic effect

rank stock order and epidemic effects in the diffusion of new process technologies an empirical model in this article we construct a general duration model of technology adoption that incorporates the main factors discussed in different theories of diffusion of new process technologies the model is applied to data on diffusion of cnc in the uk engineering industry although we find strong evidence in support of rank and endogenous learning effects there seems to be little evidence in support of the stock and order effects the main factors affecting the diffusion of cnc are found to be endogenous learning firm size industry growth rates the cost of the technology and expected changes in the cost of the technology

trade tastes and nutrition in india this paper introduces habit formation into an otherwise standard model of international trade household tastes evolve over time to favor foods consumed as a child the opening of trade causes preferred goods to rise in price as these were relatively inexpensive in autarky neglecting the correlation between tastes and agro climatic endowments overstates the short run nutritional gains from agricultural trade liberalization and masks potential caloric losses for laborers i examine the predictions of this model of trade with habit formation using household survey data from india both by looking across indian regions and by examining the consumption patterns of inter state migrants

the dynamics of technological change in uk retail banking services an evolutionary perspective abstract the purpose of this paper is to elaborate an evolutionary perspective on the process of structural change that has characterized the banking industry in the united kingdom uk for this purpose the evolution of retail financial services is contrasted against the backdrop of the implementation and development of information and communication technologies icts the paper delves into the sources and the effects of technological change in banking over a long term perspective 1840s 1990s to point out the significance of the opportunities and the constraints that have shaped the growth and development of this industry this is interpreted as a three stage evolutionary process driven by intertemporal coordination across several complementary domains including activities of production business organization consumption and the underlying regulatory setting it is concluded that the evolution of uk retail banking displays the characteristics of a distributed process of innovation in which developers of technologies service suppliers and customers contribute to the process of structural change of the industry

complementarity and cumulative learning effects in early diffusion of multiple technologies this paper concentrates on the contextual diffusion of flexible automation production and design engineering technologies in the italian metalworking industry the authors use duration data analysis with explanatory covariates to point out the role of complementarities between the technologies examined and learning by using effects matured with experience of previously available technologies in shaping diffusion paths the impact of industry and plant specific control variables as well as that of the stock of previous adopters on adoption probabilities is also taken into account in addition the authors analyze duration versus calendar time dependence of adoption probabilities copyright 1995 by blackwell publishing ltd

unobserved preference heterogeneity in demand using generalized random coefficients we model unobserved preference heterogeneity in demand systems via random barten scales in utility functions these barten scales appear as random coefficients multiplying prices in demand functions consumer demands are nonlinear in prices and may have unknown functional structure we therefore prove identification of generalized random coefficients models defined as nonparametric regressions where each regressor is multiplied by an unobserved random coefficient having an unknown distribution using canadian data we estimate energy demand functions with and without random coefficient barten scales we find that not accounting for this unobserved preference heterogeneity substantially biases estimated consumer surplus costs of an energy tax jel codes c14 d12 d13 c21 keywords unobserved heterogeneity nonseparable errors random utility parameters random coefficients equivalence scales consumer surplus welfare calculations the authors wish to thank jinyong hahn richard blundell stefan hoderlein rosa matzkin and anonymous referees for helpful discussions and suggestions earlier versions of this paper were circulated under the

the provision of incentives in firms i ncentives are the essence of economics despite many wide ranging claims about their supposed importance there has been little empirical assessment of incentive provision for workers the purpose of this paper is to critically overview existing work on the provision of incentives since the interests of workers and their employers are not always aligned a large theoretical literature has emphasized how firms design compensation contracts to induce employees to operate in the firm s interest this literature has reached into many areas of compensation and has pointed to a multitude of different mechanisms that can be used to induce workers to act in the interests of their employers these include piece rates options discretionary bonuses promotions profit sharing efficiency wages deferred compensation and so on my objective here is to evaluate this literature in the light of a growing empirical literature on compensation where possible i will address the literature from two perspectives first an underlying assumption of this literature is that individuals respond to contracts that reward performance accordingly i consider whether agents behave in this way and whether these responses are always in the firm s interest second i address whether firms write contracts with these responses in mind in other words do contracts look like the predictions of the theory incentives are provided to workers

schumpeterian dynamics an evolutionary model of innovation and imitation abstract this paper develops a simple evolutionary model of innovation and imitation it analyzes how dynamic interactions between equilibrating force of imitation and disequilibrating force of innovation mold the evolutionary pattern of an industry s state of technology and shows that in this schumpeterian world the industry will never approach a neoclassical equilibrium with perfect knowlwdge even in the long run the paper also examines the steady state efficiency distribution of firms that characterizes the industry s long run and obtains some comparative dynamics results

the drivers of climate change innovations evidence from the australian wine industry this study examined the drivers of climate change innovations and the effects of these innovations on firm outcomes in a sample of 203 firms in the south australian wine cluster the results of structural equation modeling analysis suggest that absorptive capacity has a direct effect on climate change innovations and stimulates knowledge exchanges kes between firms in the cluster kes between firms in the cluster in turn directly affect the climate change innovations the findings suggest a perhaps counterintuitive interrelationship between firm and cluster level impacts in which kes between firms in the cluster play a partial mediating role in the innovation process the study further finds that climate change innovations are related to firm performance fp and reductions in greenhouse gases ghgs mitigative innovations lead to greater ghg reductions while adaptive innovations impact on fp contributions of the findings are discussed as are future research directions

choice experiments are not conducted in a vacuum the effects of external price information on choice behavior abstract consumers carry a wealth of external knowledge and experience into a study that may affect choices in even the most well crafted experiment we derive a conceptual model showing how the level and variability of price perceptions outside the task at hand might affect choice behavior and we conduct an experiment to test the model by manipulating information provided to respondents in a way to alter the outside the experiment perceptions mixed logit error component models show that reference dependent models best describe the choice data and we find that consumer choice is significantly affected by the experiment manipulations the predictions of the model are borne out in the data as expected price sensitivity is generally higher for price changes above a price reference point than below also as predicted exogenously increasing external reference prices and exogenously reducing the variability in references prices both serve to increase the probability of making a purchase and reduce the probability of choosing none these results have important implications for the design and practice of choice experiments as they show that consumer choice is affected by perceptions of the level and variability of prices outside the experiment more generally the results highlight the need to understand the formation and distribution of reference prices when predicting consumer choice

how golden parachutes unfolded diffusion and variation of a controversial practice we contribute to a growing focus on variation in diffusion processes by examining the ways in which contested practices are modified as they spread among adopters expanding on prior diffusion accounts we argue that the extensiveness and similarity of a practice will vary in response to both population and organization level mechanisms to examine these issues we study variation in golden parachute contracts a controversial corporate governance practice that emerged and spread widely during the hostile takeover wave of the 1980s using a concept network approach to analyze the composition of parachute plans we find evidence of mechanisms that both increase and decrease extensiveness and variation of golden parachutes our findings hold implications for accounts of practice diffusion over contested terrain by revealing substantial variation in the course of diffusion

on the competitive pressure created by the diffusion of innovations abstract we consider the decision of a dominant firm to adopt a sequence of potential cost reducing innovations where the latest technology adopted diffuses to a competitive fringe at an exogenous rate with price competition on the product market the leader optimally spaces apart the adoption dates of successive innovations so the industry is characterized by schumpetarian cycles of alternating innovation and diffusion an increase in the rate of diffusion has ambiguous effects on innovative activity and up to a point hastens the pace of innovation these results may however be reversed in the case of quantity competition

interdependences in the intrafirm diffusion of technological innovations confronting the rational and social accounts of diffusion this article investigates the intrafirm diffusion of technological innovations and the interdependences that exist among rival firms in this process previous research has offered two potential explanations for these interdependences social accounts in which they result from institutional pressures and rational accounts in which firms are interdependent as a result of how adoption by rivals affects expectations about the profitability of the technology the article offers two contributions first we propose a competitive interaction mechanism that is consistent with the fundamentals of rational accounts of diffusion second the empirical analysis shows the dominance of the proposed rational mechanism over social accounts of innovation diffusion in the generation of interdependences in the process of intrafirm diffusion

a comparative analysis of reference price models the effect of reference price on brand choice decisions has been well documented in the literature researchers however have differed in their conceptualizations and therefore in their modeling of reference price in this article we evaluate five alternative models of reference price of which two are stimulus based i e based on information available at the point of purchase and three that are memory based i e based on price history and or other contextual factors we calibrate the models using scanner panel data for peanut butter liquid detergent ground coffee and tissue to account for heterogeneity in model parameters we employ a latent class approach and select the best segmentation scheme for each model the best model of reference price is then selected on the basis of fit and prediction as well as on the basis of parsimony in cases where the fits of the models are not very different in all four categories we find that the best reference price model is a memory based model namely one that is based on the brand s own price history in the liquid detergent category however we find that one of the stimulus based models namely the current price of a previously chosen brand also performs fairly well we discuss the implications of these findings

promoting clean energy technology entrepreneurship the role of external context abstract this study examines how political social and economic factors influence clean energy technology entrepreneurship cete government policies supporting clean energy technology development and the development of markets for clean energy create opportunities for cete however the extent to which such opportunities lead to the emergence of new clean energy businesses depends on a favorable external context promoting cete this study employs a novel dataset combining indicators of the policy and social context of cete with information on clean energy technology startup firms in the usa to provide empirical evidence that technological and market conditions supporting clean energy induce more extensive cete under contexts where local attention to clean energy issues and successful firms commercializing clean energy technologies are more prominent by establishing that cete is contingent upon a supportive local environment as well as technology and market opportunities the study holds relevance for policy makers and clean energy technology firms

the internal economics of the firm evidence from personnel data we analyze twenty years of personnel data from one firm the hierarchical structure is quite simple and stable career movements suggest that the employee s rate of learning and the firm s learning about ability are important there are promotion fast tracks exit rates vary little with tenure or salary the firm has personnel policies like those described in the internal labor markets literature although several theoretical preconditions for ilms such as ports of entry and exit are lacking job levels are important to compensation but there is also substantial individual variation in pay within levels our companion paper in this issue explores the wage policy of this firm

the social construction of market value institutionalization and learning perspectives on stock market reactions this study advances a social constructionist view of financial market behavior the paper suggests that the market s reaction to particular corporate practices such as stock repurchase plans are not as financial economists contend simply a function of the inherent efficiency of such practices rather stock market reactions are also influenced by the prevailing institutional logic and the degree of institutionalization of the practice the theory first predicts that the emergence of the agency perspective on corporate governance in the mid 1980s represented a powerful new institutional logic that would lead the market to reverse its prior aggregate reaction to stock repurchase plans in the united states the paper then considers the potential for institutional decoupling of repurchase plans and develops competing hypotheses about how the market value of these policies might have changed as more firms formally adopted but did not implement the plans over time in contrast to a financial economic pers

on the merit of equal pay performance manipulation and incentive setting abstract work performance is often difficult to assess thus leaving room for manipulation of commonly used metrics we created a laboratory workplace in which we can precisely assess both work performance along with manipulation activities using two independent experiments we show that whenever pay for performance is used manipulation is pervasive leading to both a waste of organizational resources and a weakening of incentives by contrast paying organizational members equally effectively deters manipulation attempts leading to higher organizational production

between preferences and references asymmetric price elasticities and the simulation of fiscal policies abstract canonical demand studies and fiscal policy simulations rest on the assumption that consumers react symmetrically to price increases and decreases such assumption has been challenged from both the empirical and theoretical points of view we propose theoretically consistent empirical specifications to estimate discrete choice models random utility dcm and continuous demand systems easi and aids demand systems that allow for reference prices and asymmetric own and cross price demand response our application focuses on the demand for sugar sweetened beverages in great britain using transaction level household purchase data and different product aggregation levels we find substantial evidence of asymmetric consumer response and loss aversion with a stronger response when prices rise above their reference level our results hold for both dcms on highly differentiated products and demand systems on aggregate product categories and are robust to alternative model and reference price specifications simulations of taxes and subsidies on soft drinks shows that ignoring asymmetry may lead to biases especially when predicting price cuts

technological innovations and sectoral change transformative capacity adaptability patterns of change an analytical framework following up on recent debates about sectoral systems of innovation and production the paper introduces a heuristic framework for analyzing and explaining distinct patterns of technology based sectoral change the concept is based on two interrelated influencing factors the first is the sectoralspecific transformative capacity of new technologies themselves that is their substantial or incremental impact on socioeconomic and institutional change in a given sectoral system the second is the sectoral adaptability of socioeconomic structures institutions and actors confronted with the opportunities presented by new technologies the first factor the sectoral transformative capacity of new technologies enables us to identify the technology based pressure to change and adjust the structural institutional and organizational architectures of the sectoral system the second complementary factor sectoral adaptability helps us to discern the distinct social patterns of anticipating and adopting this technology based pressure the specific interplay between the two influencing factors creates distinguishable modes of sectoral transformation ranging from anticipative and smooth adjustments to reactive and crisis ridden patterns of change even processes of radical sectoral change continue over longer periods of mismatch and are characterized by numerous and mostly gradual organizational structural and institutional transformations

tax design in the alcohol market abstract alcohol consumption generates negative externalities that are non linear in the total amount of alcohol consumed if tastes for products are heterogeneous and correlated with marginal externalities then varying tax rates on different products can lead to welfare gains we study this problem in an optimal tax framework and empirically for the uk market we find that heavy drinkers have systematically different patterns of alcohol demands and welfare gains from optimally varying rates are higher the more concentrated externalities are among heavy drinkers

arbitraging a discriminatory labor market black workers at the ford motor company 1918 1947 the 1918 47 employee records of the ford motor company provide a rare opportunity to study a firm willing to hire black workers when similar firms would not the evidence suggests that ford did profit from discrimination elsewhere but not by paying blacks less than whites an apparent wage equity constraint prevailed resulting in virtually no racial variation in wages inside ford an implication was that blacks quit ford jobs less often than whites holding working conditions constant arbitrage profit came from exploiting this nonwage margin as ford placed blacks in hot dangerous foundry jobs where quit rates were generally high

coming forward the effects of social and regulatory forces on the voluntary restatement of earnings subsequent to wrongdoing we investigate the effects of social and regulatory forces on a firm s decision to disclose past wrongdoing by voluntarily restating its earnings with an eight year sample of more than 2 500 public firms including 170 voluntary restaters we find that firms are more likely to voluntarily restate their earnings in response to informal social pressures from other firms in their industry and less likely to do so in response to formal regulatory sanctions we also show that the impact of these forces varies with firm status we contribute to corporate governance and public policy research that examines the effectiveness of hard versus soft deterrence measures on firm compliance

an empirical analysis of internal and external reference prices using scanner data single source yogurt data are used to examine whether both internal and external reference prices affect purchase decisions internal reference prices are memory resident prices based on actual fair or other price concepts external reference prices are observed stimuli such as regular prices that stores may display along with a sale price for comparability discrete choice models with variables representing the two types of reference prices are estimated and both types of variables are found to have significant effects on purchase probabilities this suggests that consumers may use multiple reference points in evaluating price in purchase decisions in addition a model using an indicator of a sale price discount explains purchase probabilities as well as one that models the actual discount which suggests that consumers may be reacting to the indication of savings rather than to the amount of the discount

international comparisons of r d effort the case of the canadian pharmaceutical industry abstract the canadian federal government anxious to stimulate innovation announced recently a policy objective for the economy the attainment of industrial research expenditures reaching 1 5 percent of the gross national product the proposed substantial increase over the current level is rationalized by comparison with economy wide research intensities gerd gnp in other oecd countries this paper questions the economic validity and policy relevance of international aggregate comparisons it argues that inter country comparisons should take place at individual industry levels where technologies are similar and proposes a methodology for formulating rd this canadian industry presumably does not require governmental attention to its r d activities

gone fishing reported sickness absenteeism and the weather i introduction the principal agent problem of contracting employee work effort that is imperfectly monitored arises in a number of areas of economic theory including models of remuneration by seniority lazear 1979 involuntary unemployment e g shapiro and stiglitz 1984 performance based pay macleod and malcomson 1998 and labor hoarding depken redmount and snow 2001 given the importance of this mechanism in the theoretical work the empirical research on the agency problem is remarkably scant in part this reflects the limited availability of personnel data as baker and holmstrom argue in their review article internal labour markets too many theories too few facts 1995 but more fundamentally it reflects the inherent difficulty of empirically capturing the employee effort levels that underlie the models using direct measures of employee or firm level productivity is unquestionably the preferred approach but these measures are notoriously problematic and the studies that use them tend to be case studies introducing external validity issues it is also unlikely to isolate the type of malfeasant shirking behavior that concerns variants of the models where the employee effort decision entails disciplinary risk to inform employee incentives to engage in malfeasant behavior economists have relied on two measures employee disciplinary rates e g cappelli and chauvin 1991 ichino and maggi 2000 and absenteeism rates e g arai and thoursie 2005 bradley green and leeves 2007 ichino and riphahn 2005 the difficulty is that disciplinary rates capture only shirking activity that is identified by employers not that which goes undetected while reported absenteeism particularly sickness absenteeism rates may be entirely legitimate one can therefore never be sure whether differences in these rates across workers facing different shirking costs reflect actual shirking activity as opposed to differences in employers willingness or ability to detect and punish shirkers or differences in employee health that may be correlated with these costs in this paper we identify a different type of shirking activity that potentially addresses both of these shortcomings employees misreporting health in order to exploit weather conditions favorable to high utility outdoor recreation 1 we begin by considering a shirking model of sickness absenteeism in which employees marginal utility of outdoor leisure is increasing in the interaction of two state dependent parameters health and outdoor weather quality the intuition being that ideal weather conditions for engaging in outdoor recreation are valued more when one is physically and perhaps also mentally healthy this assumption leads to two main propositions first increases in sickness absenteeism associated with marginal improvements in weather quality reflect the decisions of the inframarginal workers those workers who in the absence of the weather improvement would be present at work who are the healthiest implying an increase in absenteeism that is unambiguously illegitimate second comparing across workers marginal weather improvements should have the largest impact on sickness absenteeism where shirking costs are highest the reason is that where existing incentives to misreport health are the weakest such as where sick pay is not offered or job protection is weak existing sickness absenteeism levels will be lowest and the inframarginal workers will be the healthiest thereby benefitting most from the weather improvement we examine the empirical relevance of these propositions using a two step approach first we construct an index of weather preferences by linking temperature relative humidity precipitation wind speed and cloud cover data to time use data identifying the weekend and weekday evening outdoor recreational activities of employees with regular daytime work schedules we then examine the empirical relation between the resulting index of the recreational quality of the weather hereafter referred to simply as weather quality and the incidence of short term spells of sickness absenteeism reported in survey data comparing the magnitude of this relation across workers facing different levels of sick pay job protection and job finding rates

market structure and innovation a survey economics we all recite deals with allocation of limited resources towards satisfaction of unlimited wants resources are typically identified as land labor and capital plus a technology that determines their transformation into consumer goods disparity between the available goods and services and the desired gives rise to scarcity and the question of what how and for whom to produce the focus then shifts to description and evaluation of alternative resource allocation mechanisms for making the choices the pareto criterion by which an allocation of resources is deemed efficient if any reallocation improving the position of some individual worsens the position of others is a commonly employed gauge of a mechanism s performance in the absence of externalities increasing returns to scale and uncertainty a perfectly competitive market system yields a pareto optimal allocation of resources this underlies the view that individual self interest is compatible with society s interest the further conclusion that pareto optimality may not be achieved via the market system in the presence of monopoly elements provides an economic rationale for antitrust laws the objective of a resource allocation mechanism appears to be according to the analysis described above to make the best of available resources the alternative objective of relaxing constraints through expanding the resource base or developing new technology seems to be beyond its scope thus until rather recently technical advance had been regarded in the mainstream of economic theory as unmotivated by the quest for profits and substantially unaffected by resource allocation instead as j schmookler observed technology had been viewed as a parameter like the weather affecting the outcome of resource allocations but itself unaffected by them 84 1965 evidence that technological progress has significantly contributed to growth in productivity together with a substantial increase in research and development activity largely financed by government and carried out by industry see f machlup 51 1962 may have spurred reconsideration of this view once technical advance is regarded as an economic variable it is natural to in

the effect of prices on nutrition comparing the impact of product and nutrient specific taxes this paper provides an analysis of the role of prices in determining food purchases and nutrition using very detailed transaction level observations for a large nationally representative sample of us consumers over the period 2002 2007 using product specific nutritional information we develop a new method of partitioning the product space into relevant nutritional clusters that define a set of nutritionally bundled goods which parsimoniously characterize consumer choice sets we then estimate a large utility derived demand system over this joint product nutrient space that allows us to calculate price and expenditure elasticities using our structural demand estimates we simulate the role of product taxes on soda sugar sweetened beverages packaged meals and snacks and nutrient taxes on fat salt and sugar we find that a 20 nutrient tax has a significantly larger impact on nutrition than an equivalent product tax due to the fact that these are broader based taxes however the costs of these taxes in terms of consumer utility are only about 70 cents per household per day a sugar tax in particular is a powerful tool to induce healthier nutritive bundles among consumers

designing a tax to discourage unhealthy food and beverage purchases the case of chile the global shift towards diets high in sugar sweetened beverages ssbs and energy dense ultra processed foods is linked to higher prevalence of obesity diabetes and most other noncommunicable diseases ncds causing significant health costs chile has the highest ssb consumption in the world very high junk food intake and very rapid increases in these poor components of the diet plus obesity prevalence this study s purpose is to compare the effect of different tax schemes for ssbs and ultra processed foods on nutrient availability utilizing price elasticities which are estimated from a quadratic almost ideal demand system model using the 2011 2012 income and expenditure survey we take into account the high proportion of households not purchasing various food and beverage groups censored nature of data the food groups considered were sweets and desserts salty snacks and chips meat products and fats fruits vegetables and seafood cereals and cereal products ssb ready to drink ssb from concentrate plain water coffee and tea and milk which together represent 90 of food expenditures the simulated taxes were 1 40 price tax on ssbs 22 above the current tax level 2 a 5 cents per gram of sugar tax on products with added sugar and 3 30 price tax on all foods 27 above current tax levels and beverages 12 above the current tax level exceeding thresholds on sodium saturated fat and added sugar and for which marketing is restricted based on a chilean law effective june 16 2016 unhealthy foods are price elastic 1 99 for salty snacks and chips 1 06 for ssbs ready to drink and 1 27 for ssbs from concentrate meaning that the change in consumption is proportionally larger with respect to a change in price results are robust to different model specification and consistent among different socioeconomic sub populations overall the tax on marketing controlled foods and beverages is associated with the largest reduction in household purchases of sodium added sugar saturated fat and calorie purchases chile is unique in currently having instituted a small current ssb tax as well as marketing controls and front of package labeling of unhealthy foods and beverages the design of a larger more comprehensive tax to enhance the overall effect of these policies on healthier diets is a next critical step this study shows that a large tax on the same foods and beverages already delineated as unhealthy by the marketing controls and front of pack labeling should prove to be more effective for promoting a healthier diet

strategic commitment with r d the case of bertrand competition abstract when there is multiplicatively separable demand and firms compete in the price dimension there is no room for strategic use of r d by firms under a different demand situation strategic use of r d by firms competing in the price dimension reduces r d spending reduces output increases price and increases profits of each firm

a control function approach to endogeneity in consumer choice models abstract endogeneity arises for numerous reasons in models of consumer choice it leads to inconsistency with standard estimation methods that maintain independence between the model s error and the included variables the authors describe a control function approach for handling endogeneity in choice models observed variables and economic theory are used to derive controls for the dependence between the endogenous variable and the demand error the theory points to the relationships that contain information on the unobserved demand factor such as the pricing equation and the advertising equation the authors approach is an alternative to berry levinsohn and pakes s 1995 product market controls for unobserved quality the authors apply both methods to examine households choices among television options including basic and premium cable packages in which unobserved attributes such as quality of programming are expected to be correlated with price without correcting for endogeneity aggregate d

models of technology diffusion abstract the literature on new technology diffusion is vast and it spills over many conventional disciplinary boundaries this paper surveys the literature by focusing on alternative explanations of the dominant stylized fact that the usage of new technologies over time typically follows an s curve the most commonly found model which is used to account for this model is the so called epidemic model which builds on the premise that what limits the speed of usage is the lack of information available about the new technology how to use it and what it does the leading alternate model is often called the probit model which follows from the premise that different firms with different goals and abilities are likely to want to adopt the new technology at different times in this model diffusion occurs as firms of different types gradually adopt it there are actually many ways to generate an s curve and the third class of models which we examine are models of density dependence popularized by population ecologists in these models the twin forces of legitimation and competition help to establish new technologies and then ultimately limit their take up finally we look at models in which the initial choice between different variants of the new technology affect the subsequent diffusion speed of the chosen technology such models often rely on information cascades which drive herd like adoption behaviour when a particular variant is finally selected

inter and intra firm effects in the diffusion of new process technology using primarily the example of computerised numerically controlled machine tools cnc in the uk metalworking and engineering industry it is shown that even many years after the date of first use of a new technology although the larger proportion of firms may be using that technology because the extent of intra firm diffusion is limited the proportion of total industry output produced on that technology may be quite small using backward projection techniques it is further shown that intra firm diffusion tends to lag behind inter firm diffusion over the whole of the diffusion process and inter firm diffusion patterns and extent may thus be poor indicators of overall diffusion although intra firm diffusion is therefore crucial to the understanding of overall diffusion patterns the existing literature relating to it has severe limitations and there are no associated policy results it is argued that much greater emphasis should be placed on intra firm issues in future diffusion research it is also suggested that discussions of intra firm policy could usefully proceed within the context of already established general diffusion policy principles

the impact of hierarchies on wages abstract hierarchical production theory has only one consistent prediction that wages increase with level in a hierarchy theoretical disagreement exists as to what causes this wage premium and how it might be affected by the number of levels of superiors above an employee by empirically analyzing these issues we find that i level one supervisors receive a premium due to some unobserved characteristic ii higher level supervisors receive a premium through higher rates of return on human capital and iii the marginal effect on wages of increasing the level of an employee declines with the number of levels above the employee

on the diffusion of new technology a game theoretic approach this paper is an attempt at a rigorous albeit not exceedingly general analysis of the diffusion of new technology in particular consider an industry composed of two firms each using the current best practice technology the firms are assumed to be operating at nash equilibrium output levels generating a market price given demand and profit allocations when a cost reducing innovation is announced each firm must determine when if ever to adopt it based in part upon the discounted cost of implementing the new technology and in part upon the behavior of the rival firm if either firm adopts before the other it can expect to make substantial profits at the expense of the other firm on the other hand the discounted sum of purchase price and adjustment costs may decline with the lengthening of the adjustment period as various quasi fixed factors become more easily variable therefore although waiting costs the firm more in terms of foregone profits it may save money on the cost of purchasing the new technology thus the firm must weigh the costs and benefits of delaying adoption as well as take account of its rival s strategic behavior

intrafirm diffusion of new technologies an empirical application research on the diffusion of new technologies has centred on the study of the interfirm rate of diffusion paying much less attention to intrafirm aspects this paper attempts to overcome this gap in the literature by analysing the factors that influence the speed with which a new technology the atm is fully adopted the data over which the hypotheses are tested belongs to the spanish savings banks market the results show that the rate of intrafirm diffusion is explained by innovation firm and market characteristics in testing our hypotheses we make use of both traditional methods and survival analysis techniques

preemption and rent equalization in the adoption of new technology we study the adoption of a new technology to illustrate the effects of preemption in games of timing we show that the threat of preemption equalizes rents in a duopoly but that this result does not extend to the general oligopoly game if the gain to preemption is sufficiently small then the optimal symmetric outcome which involves late adoption is an equilibrium this contrasts with reinganum s result that in precommitment equilibria there must be diffusion we develop a new and richer formalism for modeling games of timing which permits a continuoustime representation of the limit of discrete time mixed strategy equilibria

when fashion is fleeting transitory collective beliefs and the dynamics of tqm consulting we analyze changes over time in the types of consulting firms offering total quality management services when tqm was a booming management fashion consultants tended to be generalists with weak links to the technical foundations of the practice after the fashion went bust tqm consulting was increasingly populated by specialists with quality control expertise these results suggest that fashionable practices can return to their technical roots after the hype is over reversing the usual institutional trajectory they also help explain why fashion booms are so fragile and how management practices can be sustained once a boom is over

e business usage across and within firms in the uk profitability externalities and policy using data from the third uk community innovation survey we model the usage of e business across and within firms in the uk in the year 2000 as a single observation upon an integrated process of inter and intra firm diffusion the intra firm dimension is a significant extension to standard analysis the model estimates indicate that the pattern of e business usage reflects the heterogeneity of firms in terms of size other innovative activity and labour force skills generating differences in the payoffs to use as well as market and non market intermediated externalities the policy implications of the findings are discussed c 2008 elsevier b v all rights reserved

coevolution in management fashion an agent based model of consultant driven innovation the rise of management consultancy has been accompanied by increasingly marked faddish cycles in management techniques but the mechanisms that underlie this relationship are not well understood the authors develop a simple agent based framework that models innovation adoption and abandonment on both the supply and demand sides in opposition to conceptions of consultants as rhetorical wizards who engineer waves of management fashion firms and consultants are treated as boundedly rational actors who chase the secrets of success by mimicking their highest performing peers computational experiments demonstrate that consultant driven versions of this dynamic in which the outcomes of firms are strongly conditioned by their choice of consultant are robustly faddish the invasion of boom markets by low quality consultants undercuts popular innovations while simultaneously restarting the fashion cycle by prompting the flight of high quality consultants into less densely occupied niches computational experiments also indicate conditions involving consultant mobility aspiration levels mimic probabilities and client provider matching that attenuate faddishness

internal labor markets firm specific human capital and heterogeneity antecedents of employee idiosyncratic deal requests a field study of 615 managers in 11 korean manufacturing firms extends theory regarding labor contracting to the study of idiosyncratic deals i deals despite i deals potential to benefit both employees and employers economic theory asserts that employers attempt to reduce individual contracting by use of internal labor markets ilms this study identifies limits to that assertion by identifying conditions under which i deals are sought despite employee participation in ilms furthermore we develop and test theory reconciling the roles of ilms and firm specific human capital in employee requests for i deals employee reports of ilm practices are negatively related to i deal requests whereas firm specific human capital is positively related to these requests in addition we find an interaction between the two such that the suppressive effects of ilm reports on i deal requests hold largely for workers with low firm specific human capital individuals with high firm specific human capital tend to seek i deals despite reported ilm practices i deal requests also increase with group level heterogeneity in firm specific human capital in all our findings suggest that ilms function as economic theory asserts for workers with limited firm specific human capital but they are less able to reduce i deal requests among workers with higher firm specific human capital
