behavioral demand effects when buyers anticipate inventory shortages abstract firms often worry about how buyers will react when there is an inventory shortage but the anticipation of facing a shortage may also impact buyer behavior in this paper we use a combination of theoretical modeling computational methods and laboratory experiments to understand buyers search behavior in markets where there is potential for either a costly or costless inventory shortage when inventory shortages are costly to buyers we find their equilibrium purchasing strategy generates a newsvendor problem among the firms in turn experimental data suggests buyer behavior can be explained by prospect theory better than by standard assumptions of fully rational expected utility maximizing agents indicating that potential inventory shortages generate loss aversion among buyers and there is systematic mis identification of the probability with which they will be able to procure an item using computational methods we find firms are able to extract more surplus from behavioral buyers via higher prices than would be predicted by the standard model on the other hand when inventory shortages are not costly to buyers the effect of behavioral biases on the part of buyers is not relevant but in this case there can be a benefit to reducing inventory via a reduction in price competition

national institutional structures transaction cost economizing and competitive advantage the case of japan japan s economic success since world war ii has been striking modern japan was the first major industrial economy to emerge from outside the western tradition economically devastated in 1945 by 1990 japan had the world s second largest economy and a gdp per head 20 percent greater than that of the united states in this paper it is argued that one reason for japan s success is that the costs of achieving cooperation and specialization are lower in japan than in the west cooperation and specialization have been acknowledged to have a beneficial impact upon productivity ever since adam smith wrote about cooperative specialization in the context of the division of labor modern economic theory however suggest that in a world of self interested individuals the costs of achieving cooperation and specialization are substantial in this paper it is argued that the cultural value system that japan has inherited from its preindustrial past and particularly the tokugawa period helps facilitate cooperation b

newsvendor demand chasing revisited existing research on newsvendor behavior asserts that individuals engage in demand chasing adjusting their order quantities towards prior demand several metrics have been used to identify this heuristic by simulation current metrics are shown to yield excessive false positives indicating demand chasing when the true order generating process is independent of prior demand a simple correlation measure does not suffer from this problem and is proposed here as an alternative to some of the more commonly used measures this paper was accepted by martin lariviere operations management

product and international diversification among japanese multinational firms this paper examines the relationship of performance with product and international diversification on japanese multinational firms from 1977 to 1993 we show the relationships between diversification and performance change over time through the use of multiple time periods and accounting for keiretsu membership results show that while diversity strategies vary between keiretsu and non keiretsu firms performance is not much different across time periods performance varies considerably but strategies are less variable product diversity has weak effects on firm performance only in one time period while international diversification has negative profitability and positive growth consequences in in some periods these results suggest first that diversification strategies and their effects on performance vary across time periods and generally produce some unexpected findings we do not find strong interactive diversity effects copyright 2000 john wiley sons ltd

marshallian factor market externalities and the dynamics of industrial localization abstract when an industry has thus chosen a locality for itself it is likely to stay there long so great are the advantages which people following the same skilled trade get from near neighborhood to one another a localized industry gains a great advantage from the fact that it offers a constant market for skill employers are apt to resort to any place where they are likely to find a good choice of workers while men seeking employment naturally go to places where there are many employers who need such skill as theirs the advantages of variety of employment are combined with those of localized industries in some of our manufacturing towns and this is a chief cause of their continued growth alfred marshall principles of economics 8th ed pp 271 272 1920

industrial districts old wine in new bottles harrison b 1992 industrial districts old wine in new bottles reg studies 26 469 483 according to the theory of industrial districts a new wave of economic growth is being led in a number of regions in europe north america and east asia by spatially concentrated networks of mostly small and medium sized enterprises often using flexible production technology and characterized by extensive local interfirm linkages does this amount to a re emergence of the dominance of what urban and regional economists call agglomeration economies over the well known pressures on business to spatially disperse its operations neoclassical economic theorizing from marshall to perroux provides one perspective on the contemporary industrial district phenomenon another is afforded by granovetter s more recent elaboration of the ideas of embedding under and over socialization confronting each of these theoretical approaches with the other leads me to conclude that the industrial district prototypes involv

clusters dispersion and the spaces in between for an economic geography of the banal while the geographical clustering of economic activities remains an enduring feature of the industrial landscape and a perennial source of theoretical and empirical interest the geographical scale at which external economies and agglomerative effects are now claimed to operate is on the increase such changes in the spatial form and potential causes of agglomeration over time pose important questions how should we analyse changes in the spatial extent of external economies and agglomerative effects ought we to pay more attention to the sorts of banal economic spaces thrown up as part of increasingly diffuse forms of agglomeration to answer the first of these questions it is noted how economists and geographers have explained agglomerations often in the rather singular and invariant categories of pecuniary and marshallian externalities respectively this paper considers the relevance of neo marshallian analysis and the concept of borrowed size as variations on these classical principles to an analysis of the mobility and fixity of external economies and contemporary diffuse forms of agglomeration whilst reflecting important changes in the spatial extent of industrial agglomerations they are insufficiently sensitive to the interaction of different types of external economies with different scale dependencies in answering the second question it is noted that part of the value of analysing the economic basis of largely overlooked banal intermediate places lies in what they may reveal about the functioning of diffuse forms of agglomeration

is tourism firm competitiveness driven by different internal or external specific factors new empirical evidence from spain abstract the quest to understand the multilevel antecedents of competitiveness has led to a separation of approaches on one side of the question are the environment theories that analyze the structural characteristics of the general and competitive environment on the other side are the resource based view and its extensions that highlight firm specific resources and capabilities as the main basis of firms competitiveness however in recent years the nature of competition and shifting economic conditions have given rise to new theoretical approaches that complement the assumptions underlying both environmental and firm theories specifically this study contributes by examining the regional environment effect the district effect and the strategic group effect through a study of 364 spanish tourism firms this research explores the relative importance of distinct external forces such as the general environment or country effect the regional effect the competitive environment or industry effect the district effect and internal factors such as the firm s tangible resources capabilities and strategy selection the results demonstrate that firms capabilities are more important than environment effects and tangible resources

industrial districts and regional economic development a regulation approach digiovanna s 1996 industrial districts and regional economic developoment a regulation approach reg studies 30 373 386 this paper examines the regulatory underpinnings of industrial districts as many regional governments have been forced to accept greater responsibility for their own economic futures the industrial district model has been presented as an attractive path to economic development the underlying assumption among many policy makers is that all industrial districts are based on similar models of production organization and labour relations nevertheless the comparative approach illustrates that districts which appear similar on the surface are often quite distinct particularly when the experience of workers is considered by applying the concepts of regulation theory to the experiences of emilia romagna baden wurttemberg and silicon valley this paper illustrates that flexibly specialized districts can result in a variety of social outcomes this paper concludes that the success o

labour productivity in the british and south wales coal industry 1874 1914 naked to the waist hot and grimy with labour they squatted on their heels for a few minutes and talked seeing each other dimly by the light of the safety lamps while the black coal rose jutting around them and the props of wood stood like little pillars in the low black very dark temple the day passed pleasantly enough there was an ease a go asyou please about the day underground a delightful camaraderie of men shut off alone from the rest of the world in a dangerous place and a variety of labour holing loading timbering and a glamour of mystery and adventure in the atmosphere d h lawrence 1955 the above quote from d h lawrence while perhaps over emphasizing glamour and adventure illustrates one important aspect of colliery work the intensity of a collier s effort was primarily self imposed it was the work intensity combined with other factors that determined labour productivity in the coal mines a number of articles have addressed the problem of labour productivity in coalmining during the late nineteenth and early twentieth centuries two of the most important being a j taylor s 1961 examination of productivity and technological change in britain and r h walters 1975 analysis of the same topic for south wales 1 in addition there is a rich and growing literature on the broader problem of the existence of a climacteric a downward shift in the performance of the british economy in the late nineteenth century often attributed to the failure of british entrepreneurs as represented by their seeming unwillingness to adopt the best available techniques of production 2 the purpose of this paper is to specify and estimate an empirical model of labour productivity in coalmining as well as to provide some suggestive evidence regarding the performance of entrepreneurs in this major industry 3 we believe our results provide added insight into the determination of labour productivity during this period lending support to those who argue that the failure of british entrepreneurs has yet to be proved while providing mixed evidence regarding conclusions drawn by economic historians

work environment and individual background explaining regional shirking differentials in a large italian firm the prevalence of shirking within a large italian bank appears to be characterized by significant regional differentials in particular absenteeism and misconduct episodes are substantially more prevalent in the south we consider a number of potential explanations for this fact different individual backgrounds group interaction effects sorting of workers across regions differences in local attributes different hiring policies and discrimination against southern workers our analysis suggests that individual backgrounds group interaction effects and sorting effects contribute to explaining the north south shirking differential none of the other explanations appears to be of first order importance i introduction whether individual behavior is determined by group interactions or by individual background is undoubtedly a fundamental question for the social sciences this question presented itself forcefully when we stumbled onto the following piece of evidence there appear to be significant regional differentials in the prevalence of shirking among the employees of a large italian bank in particular absenteeism and misconduct episodes are considerably more frequent in the southern branches of the bank in this paper we examine several potential explanations for this fact first individual preferences for shirking versus working may differ according to one s region of hirth we will refer to this hj othesis as one of different individual hackgrounds the second possibility is one of locational sorting low shirking types may tend to migrate to the north high shirking types may tend to migrate to the south or hoth third the northern and southern

wage rates and work intensity in the south wales coalfield 1874 1914 in a recent article in this journal hirsch and hausman 1983 attempt to identify and measure the influences determining labour productivity in the british and especially the south wales coalfield during the 40 years before the first world war in particular attention is focused on the idea commonly expressed by contemporary coal owners that the upturn in wage rates both nominal and real during the 1880s exerted a major depressing influence on labour productivity the findings of hirsch and hausman are largely consistent with the views of traditional economic historians notably taylor 1961 and walters 1975 while less emphasis is placed by hirsch and hausman upon the effects of diminishing returns they find strong support for the contention that rising wage rates played a major role in explaining decreased productivity essentially hirsch and hausman claim to offer a firm empirical foundation for the persuasive but far from conclusive arguments of taylor and walters by using regression analysis to isolate the separate influences determining labour productivity if the estimates presented by hirsch and hausman are considered legitimate their results are striking for south wales elasticities of labour productivity with respect to both nominal and real wages of approximately 0 27 are reported juxtaposition of this parameter with the nominal wage index employed by walters which rises around 55 per cent between 1888 and 1914 suggests that over 60 per cent of the 24 per cent fall in labour productivity during the same period was accounted for by rising wage rates a consistent though moderately less strong interpretation is produced if the real wage index which increases some 40 per cent in the same period is preferred the contention of this paper is that the inverse association between wages and productivity postulated by hirsch and hausman for the south wales coalfield between 1874 and 1914 is without statistical foundation the basis for this assertion is that hirsch and hausman replicate unacceptable elements in the framework albeit without the qualifications offered by walters indeed this is done by intent we employ a somewhat ad hoc model reflecting the discussion by economic historians it will be argued that this desire to test the literature leads hirsch and hausman to estimate a model for which the results are difficult to interpret and to reach conclusions that are implausible specification problems are compounded by the choice of data particularly by the adoption of the wage rate index employed by walters but also by the use of proximate indicators to measure the balance between technical progress and diminishing returns

the firms that feed industrial districts a return to the italian source italian industrial districts comprise a great variety of firms and are criss crossed by various networks and business groups although the vast majority of industrial district firms are relatively small it is a mistake to assume that they are organizationally symmetrical and that they mimic the supposedly dominant norms of the communities in which they are located larger firms frequently organize production among groups of smaller firms introduce technological innovations and expand existing markets copyright 1999 by oxford university press

how much difference is there between industrial district firms a net value creation approach abstract we argue that industrial district firms possess a number of shared resources that explain the competitive superiority of these firms these factors include common reputation intensity of exchange and combination of resources and participation of the local institutions using these shared resources we aim to address an unsolved question in the industrial district literature namely the internal heterogeneity of the clustered firms our empirical research drew upon a sample of 288 spanish manufacturing firms belonging to industrial districts findings suggest that even assuming a certain degree of homogeneity among internal district firms they develop their own particular relationships and networks and as a result exploitation of the shared resources is irregular these differences can therefore be used to explain the differences in value creation among firms

collective efficiency growth path for small scale industry this study is concerned with the growth of small local industry in developing countries and explores one particular route for understanding and fostering such growth it focuses on the clustering of firms and the competitive advantage which they derive from local external economies and joint action captured in the concept of collective efficiency following a conceptual discussion the article explores the economic and institutional conditions which enhance or hinder collective efficiency this includes a case study which suggests that responding to opportunity and crisis requires shifting from mere reliance on external economies to joint action and from ascribed to earned trust

getting to know you a theory of strategic group identity this paper develops a theory of strategic group identity that explains how strategic groups emerge in an industry and how they can affect firm behaviors and outcomes in so doing it provides a theoretical basis for the existence of strategic groups we argue that managers cognitively partition their industry environment to reduce uncertainty and to cope with bounded rationality social learning theory and social identification theory are used to describe how cognitive groups coalesce into meaningful substructures and how a group level identity emerges we describe the ways in which macro level factors condition the development of groups and their identities we introduce the notion of a strong identity which characterizes any group sufficiently recognized and attended to by members to affect individual action groups with weak identities are no more than transient agglomerations of firms and do not exist in any meaningful sense these ideas are developed into propositions that describe the conditions under which groups with strong identities are likely to emerge a second set of propositions describes their transformation over time identity strength is linked to both positive and negative outcomes in a final set of propositions we show how strategic groups with strong identities can affect firm performance resolving a longstanding problem which has plagued strategic groups research and conclude by suggesting some approaches for measurement and future research 1997 by john wiley sons ltd

employment decentralisation polycentricity or scatteration the case of barcelona at the present time most large cities in the world are polycentric and at the same time they are undergoing processes of employment decentralisation and deconcentration it has been argued that polycentricity is just an intermediate stage between monocentricity and a more unstructured chaotic and amorphous location model scatteration for the case of the polycentric barcelona the aims of this study are to test whether its employment is moving from polycentricity to scatteration and whether its employment location model is increasingly random and unstructured the results show that in spite of the decentralisation and deconcentration processes employment concentrated in centres still represents a significant percentage of total employment and new sub centres have emerged in the periphery what is more the results also show an increasing influence of employment sub centres on employment location and density conditions as a result polycentricity has been reinforced

reasons for the development of islands of innovation evidence from hertfordshire this paper analyses why innovations often cluster in a few metropolitan islands of innovation the reason for this interest is that a growing body of neo schumpeterian economic theory argues that economic recovery after periods of economic recession and depression such as we have seen during the 1980s and early 1990s is driven by innovations these do not spring up all over the country but are spatially concentrated in a small number of metropolitan regions it is therefore important to know why this is so in order to evaluate the effectiveness of various uk and eu public policies whose specific objectives are to stimulate local and regional economic development agglomeration theory is used in order to understand the driving forces behind the spatial clustering of new innovations this leads to four explanatory hypotheses these are that innovation is facilitated by agglomeration in order to reduce distance transaction costs between firms in different spaces or by local factor conditions which provide

towards a competence theory of the region this paper argues the case for extending the competence theory of the firm or more generally the competence perspective to analysis of the region the relevance of the perspective follows from the characterisation of productive systems such as firms and regions as ensembles of competences that emerge from but are not reducible to social interaction attention is drawn to an identifiable although unacknowledged convergence of ideas in the recent regional literature arguing that these ideas are best re conceptualised in terms of regional competences the cluster of hightechnology firms in the cambridge region of the uk is briefly referred to in order to illustrate the main ideas of the paper
