duopolistic vertical restraints abstract in an industry where competition exists at the wholesale level vertical restraints are not necessarily desirable from the standpoint of the manufacturers when vertical restraints are employed it is never in the form of retail price maintenance but rather in the form of franchise fee pricing when the products produced by the manufacturers are only slightly differentiated the producers may benefit from the double marginalization that arises with linear pricing such double marginalization results in higher retail prices which relieve competitive pressures

technological learning environments and organizational practices cross sectoral evidence from britain this study explores the co occurrence of technological and organizational learning processes by analyzing the adoption and use of four types of human resource management hrm practices rewarding problem solving top down management and decentralization in the 1990s across different technological learning environments using a sample of british workplaces we show that the level of use of diverse hrm practices aimed at creating different learning incentives is persistently heterogeneous across technological learning environments suggesting that hrm forms an essential part of the technological learning structure of firms copyright 2011 the author 2011 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

common marketing agency as a device for facilitating collusion in a variety of markets firms voluntarily and independently delegate control over certain aspects of marketing to common agents in this article we present an explicit model of agency delegation where firms noncooperatively select agents name output prices and choose compensation schemes we exhibit an equilibrium in which all strategic variables not merely the marketing choices delegated to agents but prices as well are selected perfectly cooperatively this cooperative equilibrium is very simple and attractive each firm sets the collusive output price and employs a commission scheme to compensate the agent although each

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

the effects of expectations on technology adoption some empirical evidence n rosenberg 1976 argues that in many markets prospective buyers for an innovation are strongly influenced by expectations concerning the timing and significance of future improvements the primary objectives of this article are to provide a model of the innovation decision process of user firms that expect improvements in current best technology and to offer an empirical study that tests the model s predictions among other results the author finds empirical support for rosenberg s argument and demonstrates theoretically that compared to models without technological expectations and learning the optimal decision process is nonmonotonic copyright 1994 by blackwell publishing ltd

determinants of environmental investments testing the structural model abstract the main purpose of this study is to provide the needed additional quantitative evidence regarding the introduction of environmental technologies and to increase the possibility for generalization and thus policy application of conclusions to achieve that purpose a conceptual model is developed and then tested on a large database of firms from various industries with the use of structural equation modeling the results show that policy measures past environmental investments the importance of environmental technologies for customers and the firm performance have a positive effect on environmental investments furthermore the results show that policy measures are a second order three factor construct

innovations and the economics of new technology spreading within and across users gaps and way forward r d subsidies are often considered the main policy tool to stimulate the competitiveness and the innovativeness of firms this is especially true for innovations designed to produce greener products or cleaner and more energy efficient technologies however a consistent literature has now shown that even when a clean or a cost reducing technology is ready available in the market its spreading within intra or across inter households or firms takes several years and in some cases decades therefore it is not only important to generate innovations via investments in r d but it is also important that such innovations are adopted and used by firms this paper briefly illustrates the main theoretical approaches to the analysis of the factors leading to inter firm diffusion and emphasise the existing gap led by the paucity of literature on intra firm diffusion a final section briefly discusses some methodological issues surrounding the diffusion of consumer non durable technologies within and across households and how ad hoc models can be used to test the validity of environmental policies

the determinants of technology adoption the case of the banking firm using data on the adoption of automatic teller machines by firms in the banking industry this study examines the relationship between the decision to adopt new technology and its determinants since banking firms differ considerably in terms of the competitive environments in which they operate focusing on this one innovation in this industry allows a stronger test of the relationship between market structure and the adoption of new technology than has been previously conducted using a failure time estimation procedure we find that larger banks and banks operating in more concentrated local banking markets register a higher conditional probability of adopting this new technology all else equal we also find that other results are consistent with the underlying model and that the bank s regulatory environment shapes its adoption decision in plausible ways

investment in technological innovations an option pricing approach abstract this paper develops a model of the optimal investment strategy for a firm confronted with a sequence of technological innovations we incorporate many of the most important characteristics of real world technology markets for example we permit innovations to be stochastic in their arrival times and their profitability we also incorporate learning so that firms adopting current innovations become better able to benefit from future innovations the model yields four distinct investment strategies the model is then used to predict actual firm policy these implications are discussed and compared with observed firm behavior

intra plant diffusion of new technology role of productivity in the study of steel refining furnaces abstract this paper examines intra plant diffusion of new technology in the japanese steel industry the introduction of the basic oxygen furnace bof was the greatest breakthrough in steel refining in the last century using unique panel data the paper estimates total factor productivity by technology type and associates the estimates with intra plant diffusion the paper finds that intra plant diffusion accounts for about a half of the industry productivity growth large plants are likely to adopt the new technology earlier but retain the old technology longer than their smaller counterparts

the impact of economics on management abstract this article analyzes the impact of economics on management by examining citations of 71 management journals aer jpe econometrica and qje have the highest impact industrial organization journals also have a particularly large impact the share of economics in management citations drops from 9 91 percent until 1995 to 5 70 percent for 1996 2005 three possible explanations for this decrease are analyzed economics research became more mathematical because management is a younger discipline it grew faster than economics in quantity and quality of research and interdisciplinary spillover of research is slower than the spillover within a discipline only the second explanation is supported by the data

are more innovative firms less vulnerable to new environmental regulation compliance with pollution limits and standards requires firms to implement adaptation processes that are not only costly themselves but also affect future profits in as much as they modify production systems and methods this paper attempts to respond to the question of how technological knowledge moderates the effect that the implementation of a new environmental regulation has on the results of affected firms the regulation selected for this study is the integrated pollution prevention and control act ippc a multivariate regression model mvrm has been applied to the regulatory event the most important implication of this paper is that technological knowledge prepares a firm for adapting to a greater environmental demand such as may be derived from a new regulation

non capital investment costs and the adoption of cad and cnc in the u s metalworking industries many studies have shown that firm size is the strongest and most consistent predictor of the adoption of technological innovations but the causes for this relationship are debated i investigate the relationships between various size measures and the adoption of computer aided design cad and computer numerically controlled cnc machine tools plant size is the dominant factor in predicting cad and cnc adoption other measures such as firm size or multiplant operations have independent effects that are not present after controlling for plant size i test four potential explanations for the results noncapital cost spreading equipment replacement risk aversion and learning there is support only for the first explanation

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

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

excessive retailing at the bertrand equilibria in oligopolistic markets where competition is in prices producers may prefer to be represented by agents that sell their products even if those agents do not provide any direct services to promote the sale of the product and even if contracting is costly contracting with the agents serves as a medium to relieve competitive pressures in the product market the benefit that a single firm derives from contracting is an increasing function of the number of firms that have already contracted with agents hence if the contracting cost is relatively low there exists a unique equilibrium where all firms contract with agents

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

an evolutionary pattern of innovation diffusion the case of flexible automation abstract the aim of this paper is to provide evidence supporting an evolutionary model of the process of innovation diffusion relying on an extensive field study the paper analyses the pattern of adoption of the entire set of innovations deriving from the flexible automation paradigm on the part of a large sample of italian metalworking firms owing to the relevance of the technology examined and to the size of the sample the case illustrates quite representatively the dynamics of the early stage of development of radical and complex innovations the main results of the paper confirm the importance of firm size and market structure to explain the characteristics of the innovation diffusion process at the same time they emphasize that the localized search procedures on the part of potential users involve a step by step approach to adoption namely the technological and organizational profile of firms turns out to play a decisive role in favouring diffusion moreover empirical support is provided for the existence of persistent market disequilibria along the diffusion paths witnessed by the extent of the retrofitting phenomenon

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

the development and use of machine tools in historical perspective abstract improvements and diffusion of machine tools have had a major impact on productivity in manufacturing industry since the industrial revolution the impact has been both direct and indirect the direct impact consists of rising labor productivity through the use of faster more accurate more mechanized machines and of the higher capital productivity through higher operating rates greater reliability and higher utilization rates the indirect impact arises as the use of new or improved machine tools has necessitated or facilitated organizational changes affecting both labor capital raw materials and energy the magnitude of these impacts has varied over the years with the areas of application as new production methods have made possible entirely new products or lowered the cost of existing products sufficiently to create new markets the first part of the paper contains a review of the historical development of machine tool technology since the industrial revolution paying particular attention to the role of interaction between producers and users of machine tools the second part focuses on the way in which recent development differs from that in earlier periods in particular it is found that the major changes in machine tool technology from the so called american system of manufactures in the early 19th century to the development of detroit automation in the 1950s have tended to improve mass production methods by contrast the development of numerical control beginning in 1948 has opened up the possibility of extending industrial production methods and automation to areas previously characterized more by handicraft methods even though this technology is not yet fully utilized it is clear that the economics of industrial production has been revolutionized by the cost reduction of small scale production relative to large scale and the degree of flexibility offered by the technology the third section of the paper deals with the present development trends particularly discussing the increasing importance of flexibility and the shifting emphasis from development of individual pieces of machinery to integration and control of entire manufacturing processes i a through the use of industrial robots the reasons for the need for greater flexibility in manufacturing are also identified

subdiscipline specific journal rankings whither applied economics in light of widespread specialization of research and teaching it seems appropriate to supplement the existing general rankings of economics journals with subdisciplinespeci c rankings that is the primary objective of this paper the availability of subdiscipline speci c rankings also permits both i alternative journal ranking methods for the general discipline that account for the breadth of a journal s impact across specialized elds and ii estimation of the relative weights implicitly associated with each eld in traditional disciplinary journal rankings the results are robust to the exclusion of self citations

the strategic choice of managerial incentives do firms with separate owners and managers maximize profits we address this question for an oligopoly where managers compete in quantities or prices as in the cournot or bertrand models and owners choose their managers incentives we find that there is a strategic aspect in the problem of selecting incentives and that profit maximizing behavior does not result in particular in the oligopoly we study the behavior of firms competing in quantity price more closely resembles perfectly competitive collusive behavior than cournot bertrand behavior

intra firm diffusion of green energy technologies and the choice of policy instruments environmental benefits only unfold if green environmentally friendly technologies are widely diffused and intensively deployed within a firm we investigate how different types of policies directly and in combination affect the number of different green energy technologies adopted by a single firm intra firm diffusion using data from a dedicated survey on the diffusion of green energy technologies of 1200 swiss firms and applying well identified econometric models we found that energy taxes are a very effective policy instrument for the intra firm diffusion of green energy technologies even more important however are non political measures that show the largest effect among all tested instruments additional analyses show that a time consistency in policy making is more important for energy tax regimes than for regulations and b no evidence for complementarities between the policy types could be identified

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

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

firm size and the adoption of flexible automation data on the diffusion of flexible automation systems in the italian metalworking industry are used to point out the role of size for the adoption of complex systemic innovations plant and firm sizes turn out to be positively correlated to adoption rates moreover adoption is more likely ceteris paribus in plants which are part of large industrial groups this pattern applies in general and is particularly remarkable for more advanced solutions in this light guidelines for industrial policies that focus on financial support the diffusion of industrial standards and the correction of asymmetries in the availability of know how and skills are proposed

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

the journals of economics we examine the principal journals of economics with particular attention to the communication between journals as reflected by the network of interjournal citations during 1987 90 and the changes over the past century in the characteristics of the authors and the techniques they have used the numerical results and those of the statistical modeling of these results reinforce the importance of economic theory as an exporter of intellectual influence to applied economics the study includes an examination of the degree of specialization among different subfields of economics a statistical model is presented for measuring the flow of intellectual influence as measured by citations in terms of simple univariate scores
