where do markets come from production markets have two sides producers are a fully connected clique transacting with buyers as a separate but aggregated clique each producer is a distinctive firm with a distinctive product each side continually monitors reactions of the other through the medium of a joint social construction the schedule of terms of trade each producer is guided in choice of volume by the tangible outcomes of other producers not by speculation on hypothetical reactions of buyers to its actions each producer acts purely on self interest based on observed actions of all others summarized through a feedback process the summary is the terms of trade schedule which reduces to constant price only in limiting cases the market emerges as a structure of roles with a differentiated niche for each firm explicit formulae both for firms and for market aggregates are obtained by comparative statics methods for one family of assumptions about cost structures and about buyers evaluations of differentiated products not just any set of firms can sustain terms of trade with any set of buyers there prove to be three main kinds of markets and three sorts of market failure within a parameter space that is specified in detail one sort of market paradox has a madison avenue flavor another is more conventional grind and a third crowded is a new form not included in any existing theory of markets current american industrial markets are drawn on for 20 illustrations of which three are presented in some detail inequality in firms market shares measured by gini coefficients is discussed

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

strategic price complexity in retail financial markets abstract there is mounting empirical evidence to suggest that the law of one price is violated in retail financial markets there is significant price dispersion even when products are homogeneous also despite the large number of firms in the market prices remain above marginal cost and may even rise as more firms enter in a non cooperative oligopoly pricing model i show that these anomalies arise when firms add complexity to their price structures complexity increases the market power of the firms because it prevents some consumers from becoming knowledgeable about prices in the market in the model as competition increases firms tend to add more complexity to their prices as a best response rather than make their disclosures more transparent because this may substantially decrease consumer surplus in these markets such practices have important welfare implications

cross hedging minimum return guarantees basis and liquidity risks we reveal pitfalls in the hedging of insurance contracts with a minimum return guarantee on the underlying investment e g an external mutual fund we analyze basis risk entailed by hedging the guarantee with a dynamic portfolio of proxy assets for the funds we also take account of liquidity risk which arises since the insurer may need to advance funds for performing the hedge based on a least squares monte carlo simulation we study the economic implications of basis and liquidity risks we demonstrate that both risks may be surprisingly high and show how the design of the contract and the hedging strategy may help to alleviate them

bargain hunting or star gazing investors preferences for stock mutual funds investors who wish to purchase shares in mutual funds balance many types of information from a variety of sources when making their fund selection this research examines how investors choose a mutual fund within a given class of funds among the major findings are that investors pay a great deal of attention to past performance and vastly overweight loads relative to expense ratios when evaluating a fund s overall fee structure i also find that investors with a greater knowledge of basic finance are less likely not more likely to make reasonable fund choices

close but no cigar the bimodal rewards to prize seeking this article examines the economic effects of prizes with implications for the diversity of market positions especially in cultural fields many prizes have three notable features that together yield an emergent reward structure 1 consumers treat prizes as judgment devices when making purchase decisions 2 prizes introduce sharp discontinuities between winners and also rans and 3 appealing to prize juries requires costly sacrifices of mass audience appeal when all three conditions obtain winning a prize is valuable but seeking it is costly so trying and failing yields the worst outcome a logic we characterize as a tullock lottery we test the model with analyses of oscar nominations and hollywood films from 1985 through 2009 we create an innovative measure of prize seeking or oscar appeal on the basis of similarity to recent nominees in terms of such things as genre plot keywords and release date we then show that oscar appeal has no effect on profitability however this zero order relationship conceals that returns to strong oscar appeals are bimodal with super normal returns for nominees and large losses for snubs we then argue that the effect of judgment devices on fields depends on how they structure and refract information

why the microbrewery movement organizational dynamics of resource partitioning in the u s brewing industry1 the number of small specialty brewers in the u s beer brewing industry has increased dramatically in recent decades even as the market for beer became increasingly dominated by mass production brewing companies using the resource partitioning model of organizational ecology this article shows that these two apparently contradictory trends are fundamentally interrelated hypotheses developed here refine the way scale competition among generalist organizations is modeled and improve the theoretical development of the sociological bases for the appeal of specialist organizations products especially those related to organizational identity evidence drawn from qualitative and quantitative research provides strong support for the theory the article offers a brief discussion of the theoretical and substantive issues involved in application of the model to other industries and to other cultures

reprint of investors distraction and strategic repricing decisions abstract in this paper i analyze investors reactions to changes in the expense ratios of equity mutual funds i show that investment flows response to fees cannot be fully explained by looking at investors performance sensitivity while performance sensitivity monotonically increases with past performance price sensitivity does not investors who buy top past performers seem to be distracted by the fund s previous return and pay relatively little attention to the expense ratios moreover price sensitivity increases with fund visibility while performance sensitivity decreases and while looking at data from 1986 to 2006 no discernible trend can be observed in the average performance sensitivity price sensitivity strongly increases due to the dramatic increase in the availability of mutual funds information for retail investors finally i show that investment companies strategically time their repricing decisions in order to exploit time variations in price and performance sensitivities and that fund governance quality affects the degree to which investment companies engage in this opportunistic behavior

cultural industries in international business research progress and prospect cultural industries systems of organizations that produce and distribute cultural goods with substantive symbolic aesthetic or artistic value represent an important exciting and complex context that receives growing scholarly attention as the first review of management research on cultural industries this paper aims to provide a systematic synthesis of current research summarizing distinctive characteristics of cultural industries and highlighting research gaps we also illustrate how the unique nature dynamics and evolution of cultural industries provide opportunities to broaden international business theories in four research themes i e internationalization strategy cross border innovation social inclusion in the global economy and emerging market research

identity claims and diffusion of sustainability report evidence from korean listed companies 2003 2010 this study integrates theories of diffusion and social identity to conceptualize the diffusion of sustainability report sr as a result of a firm s identification with its reference groups specifically we first hypothesize four different sources of external stakeholder pressures driving the diffusion next we argue that the source of external stakeholder pressures has a differential effect on the adoption of sr for firms that claim their identity on sustainability management for firms with organizational identity claims in group stakeholder pressure will amplify whereas out group stakeholder pressure will dampen the adoption we test our theory using an event history analysis of 675 publicly traded firms in korea during the period of 2003 2010 the results show that all four sources of external pressure serve as mechanisms through which sr spread in korea more importantly we find support for the moderating role of organizational identity claims in the effect of external pressures we discuss how organizational identity matters in the diffusion of corporate social initiatives along with implications for policy makers

costly search and mutual fund flows this paper studies the flows of funds into and out of equity mutual funds consumers base their fund purchase decisions on prior performance information but do so asymmetrically investing disproportionately more in funds that performed very well the prior period search costs seem to be an important determinant of fund flows high performance appears to be most salient for funds that exert higher marketing effort as measured by higher fees flows are directly related to the size of the fund s complex as well as the current media attention received by the fund which lower consumers search costs

the persistence of risk adjusted mutual fund performance the authors examine predictability for stock mutual funds using risk adjusted returns they find that past performance is predictive of future risk adjusted performance applying modern portfolio theory techniques to past data improves selection and allows the authors to construct a portfolio of funds that significantly outperforms a rule based on past rank alone in addition they can form a combination of actively managed portfolios with the same risk as a portfolio of index funds but with higher mean return the portfolios selected have small but statistically significant positive risk adjusted returns during a period where mutual funds in general had negative risk adjusted returns copyright 1996 by university of chicago press

a solution concept for network games the role of multilateral interactions abstract we propose an allocation rule that takes into account the importance of both players and their links and characterize it for a fixed network our characterization is along the lines of the characterization of the position value for network games by van den nouweland and slikker 2012 the allocation rule so defined admits multilateral interactions among the players through their links which distinguishes it from the other existing rules next we extend our allocation rule to flexible networks a la jackson 2005

a one stage model of link formation and payoff division abstract in this paper we introduce a strategic form model in which cooperation structures and divisions of the payoffs are determined simultaneously we analyze the cooperation structures and payoff divisions that result according to nash equilibria strong nash equilibria and coalition proof nash equilibria we find that no cycle will be formed if a player claims a positive amount for the formation of one of its links and that a player does not necessarily profit from a central position in a cooperation structure journal of economic literature classification numbers c71 c72

media legitimation effects in the market for initial public offerings in this study we argue that media provided information affects investors impressions of newly public firms in 225 initial public offerings ipos the volume of mediaprovided information had a negative diminishing relationship with underpricing and a positive diminishing relationship with stock turnover on the first day of trading the relationship between the tenor of media provided information and underpricing increases at a nonlinear rate and decreases similarly for turnover findings provide important evidence that publicly available information not only reflects ipos legitimacy but also adds to their legitimacy and influences investor behavior in the last 20 years an increasing amount of research on markets has been conducted from a social constructionist perspective emphasizing how social structures enhance the flow of useful and credible information that market participants use to reduce the uncertainty of market exchanges e g aldrich fiol 1994 zuckerman 1999 further recent organizational research has begun to stress the influence of information intermediaries such as financial analysts and the media on mar

investment with a conscience examining the impact of pro social attitudes and perceived financial performance on socially responsible investment behavior this article addresses the growing industry of retail socially responsible investment sri profiled mutual funds very few previous studies have examined the final consumer of sri profiled mutual funds therefore the purpose of this study was to in an exploratory manner examine the impact of a number of pro social financial performance and socio demographic variables on sri behavior in order to explain why investors choose to invest different proportions of their investment portfolio in sri profiled funds an ordinal logistic regression analysis on 528 private investors revealed that two of the three pro social variables had a positive impact on how much the consumer invested in sri profiled funds moreover there was proof of a non altruistic motive for investing in sri as consumers who perceive that financial return of sri is equal or better than regular mutual funds invested a greater proportion of their portfolio in sri profiled mutual funds furthermore the results showed that women and better educated investors were more likely to invest a greater proportion of their investment portfolio in sri overall the findings indicate that both financial perceptions and pro social attitudes are connected to consumer investment in sri

managerial cognition and the mimetic adoption of market positions what you see is what you do managers planning to abandon a market position need to find a promising alternative and face a choice of inventing a new market position or entering an existing one the great uncertainty on the consequences of different actions leads them to rely on other organizations for information on how to compete making adoption of existing market positions likely their wish to avoid direct rivalry and maximize growth leads them to seek out information on new market positions with few incumbents as a result recently innovated market positions are mimetically adopted by organizations that can easily observe previous adoptions and see them as relevant to their market situations increasing the market differentiation this theory is tested and supported by analysis of the spread of new radio formats in the united states 1998 john wiley sons ltd

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

economic behavior in institutional environments the corporate merger wave of the 1980s over the last 100 years the united states has experienced four waves of corporate merger activity the first occurred at the turn of the century then again in the 1920s the 1960s and the 1980s most research on merger waves has focused on individual mergers within a wave our research focuses on the wave itself we develop a theoretical model that centers on the actors who promote the mergers and on those changes in the political and economic environments that provide the resources these actors need to act specifically we argue that a permissive state combined with increased access to capital market funds encourages fringe players to initiate the innovations that enable them to execute mergers merger waves occur when these actors become increasingly successful and their innovations are imitated throughout the business community we provide empirical support for the model using data from the 1980 s merger wave

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

cross border relocations of headquarters in europe this paper analyzes the relocations of both corporate and regional headquarters hq in a multi country setting on the basis of a dataset of 52 cross border hq relocations in europe during 1996 2006 we document an increasing trend toward relocation push and pull factors affecting hq location choice and catalyzing factors that affect the relocation decision high taxes and a high employment rate represent push factors that we find to increase the likelihood of hq relocation in particular at the mean rate of corporate tax a one percentage point increase in tax translates into a 6 8 increase in hq relocation likelihood in contrast central location and low taxes represent pull factors that increase the attractiveness of the hq location in terms of catalyzing factors we find that export oriented companies and regional hq have a higher tendency to relocate as a whole we extend the existing research by putting forward a conceptual framework of hq relocation decisions and by providing novel empirical evidence on the hq relocation phenomenon our findings contribute to an improved understanding of the determinants of corporate hq relocation decisions and provide important tax policy considerations for public policy decision makers in individual european countries and in the european commission

when market information constitutes fields sensemaking of markets in the commercial music industry in this paper we outline a key mechanism through which organizational fields are constituted we suggest that in competitive fields the market serves as a magnet around which groups of actors consolidate and that cognition of markets occurs through the creation distribution and interpretation of a web of information about the market to illustrate our theory we present a case study of thebillboard music chart from the commercial music industry to show that changes in either scope methodology or political tone with which market information is presented can provide a major jolt to the participants understanding of their field

misinformed speculators and mispricing in the housing market this paper examines the contribution of out of town second house buyers to mispricing in the housing market we show that demand from out of town second house buyers during the mid 2000s predicted not only house price appreciation rates but also implied to actual rent ratio appreciation rates a proxy for mispricing we then apply a novel identification strategy to address the issue of reverse causality we give supporting evidence that out of town second house buyers behaved like misinformed speculators earning lower capital gains misinformed and consuming smaller dividends speculators

when cheaper is better fee determination in the market for equity mutual funds abstract in this paper we develop a model of the market for equity mutual funds that captures three key characteristics of this market first there is competition among funds second fund managers ability is not observed by investors before making their investment decisions third some investors do not make optimal use of all available information the main results of the paper are that 1 price competition is compatible with positive mark ups in equilibrium and 2 worse performing funds set fees that are greater or equal to those set by better performing funds these predictions are supported by available empirical evidence

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

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

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

understanding gentrification an empirical analysis of the determinants of urban housing renovation abstract the back to the city phenomenon presented an unpredicted countercurrent in the prevalent tide of suburbanization and this process of upper income resettlement in the inner city has been thoroughly analyzed in the urban economic literature housing renovation a process that always accompanies gentrification and constitutes a significant portion of residential housing investment has been studied much less contrary to the expectation that location matters the existing empirical studies have concluded that most neighborhood amenities and structural attributes are insignificant as determinants of renovation using a detailed parcel level data set that documents all residential renovation activity in chicago between 1995 and 2000 this paper establishes that the characteristics of a building and its neighborhood do indeed influence the likelihood that it will be renovated

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

are investors rational choices among index funds s p 500 index funds represent one of the simplest vehicles for examining rational behavior they hold virtually the same securities yet their returns differ by more than 2 percent per year although the relative returns of alternative s p 500 funds are easily predictable the relationship between cash flows and performance is weaker than rational behavior would lead us to expect we show that selecting funds based on low expenses or high past returns outperforms the portfolio of index funds selected by investors our results exemplify the fact that in a market where arbitrage is not possible dominated products can prosper

bidding for surplus in network allocation problems in this paper we study non cooperative foundations of network allocation rules we focus on three allocation rules the myerson value the position value and the component wise egalitarian solution for any of these three rules we provide a characterization based on component efficiency and some balanced contribution property additionally we present three mechanisms whose equilibrium payoffs are well defined and coincide with the three rules under consideration if the underlying value function is monotonic non monotonic value functions are shown to deal with allocation rules applied to monotonic covers the mechanisms are inspired by the implementation of the shapley value by perez castrillo and wettstein bidding for the surplus a non cooperative approach to the shapley value j econ theory 100 2 2001 274 294

inferior products and profitable deception we analyse conditions facilitating profitable deception in a simple model of a competitive retail market firms selling homogenous products set anticipated prices that consumers understand and additional prices that naive consumers ignore unless revealed to them by a firm where we assume that there is a binding floor on the anticipated prices our main results establish that bad products those with lower social surplus than an alternative tend to be more reliably profitable than good products specifically 1 in a market with a single socially valuable product and sufficiently many firms a deceptive equilibrium in which firms hide additional prices does not exist and firms make zero profits but perversely 2 if the product is socially wasteful then a profitable deceptive equilibrium always exists furthermore 3 in a market with multiple products since a superior product both diverts sophisticated consumers and renders an inferior product socially wasteful in comparison it guarantees that firms can profitably sell the inferior product by deceiving consumers we apply our framework to the mutual fund and credit card markets arguing that it explains a number of empirical findings regarding these industries

hot hands in mutual funds short run persistence of relative performance 1974 1988 the relative performance of no load growth oriented mutual funds persists in the near term with the strongest evidence for a one year evaluation horizon portfolios of recent poor performers do significantly worse than standard benchmarks those of recent top performers do better though not significantly so the difference in risk adjusted performance between the top and bottom octile portfolios is six to eight percent per year these results are not attributable to known anomalies or survivorship bias investigations with a different previously used data set and with some post 1988 data confirm the finding of persistence

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

design choices in privatized social security systems learning from the swedish experience in the 2000 u s presidential campaign george w bush advocated a partial privatization of the social security system according to his plan a portion of the payroll tax would be designated for individual savings accounts at the same time as this issue was being debated in the united states sweden was in the process of launching a system that is very similar to president bush s proposal although bush s plan did not get much attention in the early years of his administration the proposal may resurface either in the united states or in other countries if so important lessons can be learned from the swedish experience in particular the swedish plan adopted an interesting mix of design choices that can now be evaluated based on three years of post implementation experience although there is a large literature in economics on the design of social security systems most of that literature is concerned with macroeconomic considerations such as funding in contrast there has been much less attention devoted to the details of how plans might be designed in part because these details do not seem important from a standard economic perspective in this paper we reverse this usual pattern and focus our attention on the design aspects of the swedish plan we find that although most of the design choices are those that might be approved by most economists in some cases these choices produced undesirable consequences

a strategic model of social and economic networks we study the stability and efficiency of social and economic networks when self interested individuals can form or sever links first for two stylized models we characterize the stable and efficient networks there does not always exist a stable network that is efficient next we show that this tension persists generally to assure that there exists a stable network that is efficient one is forced to allocate resources to nodes that are not responsible for any of the production we characterize one such allocation rule the equal split rule and another rule that arises naturally from bargaining of the players

social network effects on the extent of innovation diffusion a computer simulation of innovation diffusion no longer focus exclusively on explaining the rate at which innovations diffuse or the sequence in which they are adopted they also focus on explaining why certain innovations diffuse extensively be coming de facto standards whereas others do so partially or not at all many of these theories specify a bandwagon process a positive feedback loop in which increases in the number of adopters create stronger bandwagon pressures and stronger bandwagon pressures in turn cause increases in the number of adopters factors affecting if and how many times this feedback loop cycles explain if and how many potential adopters jump on a bandwagon we argue that one important factor has not yet been incorporated into theories explaining bandwagons extent the structure of social net works through which potential adopters of innovations find out information about these innovations which can cause them to adopt these innovations we advance a theory of how the structure of social networks affects bandwagons extent we propose that both the number of network links as well as small seemingly insignificant idiosyncracies of their structures can have very large effects on the extent of an innovation s diffusion among members of a social network

the gains from pension reform we classify social security pension systems in three dimensions actuarial versus non actuarial funded versus unfunded and defined benefit versus defined contribution systems recent pension reforms are discussed in terms of these dimensions shifting to a more actuarial system reduces labor market distortions although limiting the scope for redistribution shifting to a funded system may increase saving redistribute income to future generations and distort contermporary labor supply a partial shift to a funded system helps individuals diversify their pension assets a shift from a defined benefit to a defined contribution system means that income risk will be shifted from workers to pensioners

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

the performance of bond mutual funds using linear and nonlinear models the authors examine two samples of bond funds one sample designed to eliminate survivorship bias and a second much larger sample overall and for subcategories of bond funds they find that bond funds underperform relevant indexes postexpenses the authors results are robust across a wide choice of models they find that on average a percentage point increase in expenses leads to a percentage point decrease in performance the nonlinear model weights closely match actual composition weights the authors find no evidence of predictability using past performance to predict future performance for their unbiased sample copyright 1993 by university of chicago press

speculating on home improvements we develop a speculation based theory of home improvements housing services are produced from a mix of land and structures homeowners have an option to increase their structures i e make improvements holding xed their land speculative improvements arise because overcondent homeowners mistakenly believe they can add to structures for a lower cost than a competitive construction industry improvements are increasing and convex in home prices there is excessive home remodeling in equilibrium and the change in the recoup ratio the ratio of resale value of improvements to construction costs is negatively correlated with construction cost growth controlling for home price appreciation we provide evidence consistent with our theory using data on the costs and recoup values of remodeling projects across u s cities

asset float and speculative bubbles we model the relationship between asset float tradeable shares and speculative bubbles investors with heterogeneous beliefs and short sales constraints trade a stock with limited float because of insider lockups a bubble arises as price overweighs optimists beliefs and investors anticipate the option to resell to those with even higher valuations the bubble s size depends on float as investors anticipate an increase in float with lockup expirations and speculate over the degree of insider selling consistent with the internet experience the bubble turnover and volatility decrease with float and prices drop on the lockup expiration date

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

cooperative interconnection settlement among isps through nap abstract this paper studies the settlement problem among internet service providers isps who interconnect with each other through network access point nap a cooperative game framework is adopted for the analysis two commonly adopted allocations i e the non settlement profit allocation and the shapley value based profit allocation are analyzed and compared we check whether these two allocations can encourage isps to interconnect with each other i e in the core of the game and at the same time demonstrate fairness in settlement our results show that the non settlement allocation is not in the core and does not preserve fairness and the shapley value based profit allocation is in the core and demonstrates fairness however the complex structure of shapley value makes it difficult to understand for isps and hard to be implemented at nap especially when isps can only make their pricing decisions independently therefore we propose a characterized profit allocation cpa which is in the core preserves fairness and is easy to interpret we further propose a settlement rule based on cpa which enables the isps to act independently but achieve global optimality we also extend our basic model to incorporate interconnection quality decisions and market competition and show that the proposed settlement rule and its extended form work well in these scenarios numerical experiments confirm that cpa and its corresponding settlement rule can effectively encourage interconnection among isps and motivate isps to expand their networks

the international diffusion of public sector downsizing network emulation and theory driven learning we examine change in the size of the public sector between 1980 and 1997 across twenty six organization for economic cooperation and development oecd member nations with particular attention to diffusion dynamics general method of moments gmm analyses demonstrate imitation of shifts in government employment within the united states and mutual influence among nations that are geographically proximate and that trade extensively disaggregated analyses show that downsizing is contagious while upsizing is not proximate downsizers but not upsizers are imitated and states act on evidence that downsizing is economically beneficial while ignoring evidence that it is harmful we argue that these asymme tries in emulation and learning are a product of the dominance of neoliberal and managerialist discourses that legitimate and theorize shrinking the public sector the twentieth century as a whole and particularly the three decades after world war ii witnessed steady growth in government size and responsibility states devel oped extensive social safety nets actively managed aggregate demand and regu lated a widening swath of economic and social life this trajectory of expansion was linked to powerful forces of economic development and demographic change and anchored in a broad political consensus 1 the 1980s and 1990s saw a sea change in the rate of public sector growth brit ish prime minister margaret thatcher and u s president ronald reagan led the way with privatization outsourcing and load shedding of public responsibilities but the shift in direction was not limited to radicals on the right country reports
