the impact of national culture on software piracy this paper examines the impact of the level of economic development income inequality and five cultural variables on the rate of software piracy at the country level the study finds that software piracy is significantly correlated to gnp per capita income inequality and individualism implications for anti piracy programs and suggestions for future research are developed

financial illiteracy and pension contributions a field experiment on compound interest in china i conduct a field experiment to study the relationship between peoples misunderstanding of compound interest and their pension contributions in rural china i find that explaining the concept of compound interest to subjects increased pension contributions by roughly 40 the treatment effect is larger for those who underestimate compound interest than for those who overestimate compound interest moreover financial education enables households to partially correct their misunderstanding of compound interest i structurally estimate the level of misunderstanding of compound interest and conduct a counterfactual welfare analysis lifetime utility increases by about 10 if subjects misunderstanding of compound interest is eliminated authors have furnished an internet appendix which is available on the oxford university press web site next to the link to the final published paper online

a simple model of voice we think of voice as a means of information aggregation within groups operating in a variety of settings we explore how the characteristics of groups and their leaders influence voice in relatively homogeneous groups members farthest away from the leader have the best incentives to provide information and their voice tends to moderate policy decisions in large heterogeneous groups where leaders cannot identify individual members the possibilities for informational exchange are severely limited and any communication that exists pushes policies farther to the extreme

communication networks knowledge and decisions that communication pervades the everyday life of organizations is a statement of the obvious how this widespread communication affects organization s performance is less clear another truism about organizations is that their members are seldom fully knowledgeable of the exact state of the world in which they operate to overcome this information uncertainty burden organizations tend to devote a substantial amount of resources to retrieve information about their environment individual experimentation is a natural way to obtain superior information when the nature and the consequences of the prevailing uncertainty is common to all organization members a natural substitute for replications of individual experiments is to have agents communicate their private information among themselves communication is then a means to save on experimentation costs when they display diminishing returns in another vein shared information fosters coordination between individual agents which is beneficial to the organization as a whole when coordinated actions lead to higher benefits for everyone altogether when each organization member individually ascertains that both uncertainty and coordination are the main driving networked interactions

governing adaptation super 1 to remain competitive an organization must both respond to information about its environment and coordinate its activities we analyse how the allocation of decision rights within an organizational hierarchy influences the organization s ability to solve such problems of coordinated adaptation when information is both soft and distributed inside the organization and the organizational participants behave strategically the results show that contrary to the common intuition the performance differential between centralized and decentralized decision making is non monotone in the importance of coordination further both these common structures are dominated by asymmetric structures in sufficiently asymmetric environments such as a small division developing a new product in the presence of a large division with an established product finally if the incentive conflicts between the participants can be made sufficiently small centralized decision making is always dominated by decentralized decision making copyright 2008 wiley blackwell

assessing the energy implications of replacing car trips with bicycle trips in sheffield uk a wide range of evidence supports policies which encourage people to cycle more and drive less for health and environmental reasons however the likely energy implications of such a modal shift have remained relatively unexplored in this paper we generate scenarios for increasing the cycling rate in sheffield between 2010 and 2020 this is done through the novel application of a simple model borrowed from population ecology the analysis suggests that pro cycling interventions result in energy savings through reduced consumption of fuel and cars and energy costs through increased demand for food the cumulative impact is a net reduction in primary energy consumption the magnitude of which depends on a number of variables which are subject to uncertainty based on the evidence presented and analysed in this paper we conclude that transport policy has a number of important energy implications some of which remain unexplored we therefore advocate the formation of closer links between energy policy and transport policy in academia and in practice our approach provides a simple yet flexible framework for pursuing this aim in the context of modal shift

access based consumption the case of car sharing access based consumption defined as transactions that can be market mediated but where no transfer of ownership takes place is becoming increasingly popular yet it is not well theorized this study examines the nature of access as it contrasts to ownership and sharing specifically the consumer object consumer consumer and consumer marketer relationships six dimensions are identified to distinguish among the range of access based consumptionscapes temporality anonymity market mediation consumer involvement the type of accessed object and political consumerism access based consumption is examined in the context of car sharing via an interpretive study of zipcar consumers four outcomes of these dimensions in the context of car sharing are identified lack of identification varying significance of use and sign value negative reciprocity resulting in a big brother model of governance and a deterrence of brand community the implications of our findings for understanding the nature of exchange consumption and brand community are discussed

financial literacy and mortgage equity withdrawals abstract mortgage equity withdrawals mew are correlated with covariates consistent with a permanent income framework augmented for credit constraints we assess linkages between mew and financial literacy education using the health and retirement study hrs and panel study of income dynamics psid we find that the financially literate are 3 5 percentage points less likely to withdraw housing equity via non home equity loan mortgages using the hrs while college graduates are 5 percentage points less likely than those without a high school degree in the psid among those withdrawing housing equity in the psid college graduates extract significantly less equity and are less likely to have high levels of housing leverage after doing so

preferred solutions to the energy crisis as a function of causal attributions results of two studies support the hypotheses that those accepting personal responsibility for the energy crisis favor and report adopting the personal solution of voluntary energy conservation and those making attributions to nonpersonal causes opec oil companies u s government are most likely to favor nonpersonal solutions implications are discussed

knowing what others know coordination motives in information acquisition we explore how optimal information choices change the predictions of strategic models when a large number of agents play a game with strategic complementarity information choices exhibit complementarity as well if an agent wants to do what others do they want to know what others know this makes heterogeneous beliefs di cult to sustain and may generate multiple equilibria in models with substitutability agents prefer to difierentiate their information choices we use these theoretical results to examine the role of information choice in recent price setting models and to propose modeling techniques that ensure equilibrium uniqueness

face to face communication in organizations communication is integral to organizations and yet field evidence on the relation between communication and worker productivity remains scarce we argue that a core role of communication is to transmit information that helps co workers do their job better we build a simple model in which workers choose the amount of communication by trading off this benefit against the time cost incurred by the sender and use it to derive a set of empirical predictions we then exploit a natural experiment in an organization where problems arrive and must be sequentially dealt with by two workers for exogenous reasons the first worker can sometimes communicate face to face with their colleague consistently with the predictions of our model we find that 1 the second worker works faster at the cost of the first worker having less time to deal with incoming problems when face to face communication is possible 2 this effect is stronger when the second worker is busier and for homogenous and closely located teams and 3 the career incentives of workers determine how much they communicate with their colleagues we also find that workers partially internalise social outcomes in their communication decisions our findings illustrate how workers in teams adjust the amount of mutual communication to its costs and benefits

on the design of hierarchies coordination versus specialization we consider an economy that has to decide how assets are to be used agents have ideas but these ideas conflict we suppose that decision making authority is determined by hierarchy each asset ha

demand uncertainty and sales a study of fashion and markdown pricing the theory of clearance sales is expanded and applied to explain why markups markdowns and the frequency of sales of merchandise sold by department stores have increased dramatically in recent years and why they differ across merchandise groups tha major theme of the paper is that the growing role of fashion and product variety is an important reason for these increases and for the differences between merchandise groups the growing importance of fashion is illustrated by documenting the declining use of whites and the increasing use of colors and prints estimates of the effects of imports and technological and demographic changes on markups and markdowns are presented copyright 1988 by american economic association

change and complementarities in the new competitive landscape a european panel study 1992 1996 this paper addresses three weaknesses in the literature on new organizational forms the limited mapping of the extent of contemporary organizational change confusion about how contemporary changes link together and the lack of systematic testing of the performance consequences of this kind of change drawing on a large scale survey of organizational innovation in european firms the paper finds widespread but not revolutionary change in terms of organization structure processes and boundaries using the economics notion of complementarities the paper develops contingency and configurational approaches to suggest that organizational innovations will tend to cluster in particular ways and that the performance benefits of these innovations depend on their clustering complementarities in performance are explored from both inductive and deductive perspectives consistent with the expectations of complementarity theory high performing firms appeared to be innovating more and differently than low performing firms again consistent with complementarities piecemeal changes with the exception of it were found to deliver little performance benefit while exploitation of the full set of innovations was associated with high performance though few european firms were found to exploit the complementarities of new organizational practices those that did enjoyed high performance premia

a model of expertise we study a model in which perfectly informed experts offer advice to a decision maker whose actions affect the welfare of all experts are biased and thus may wish to pull the decision maker in different directions and to different degrees when the decision maker consults only a single expert the expert withholds substantial information from the decision maker we ask whether this situation is improved by having the decision maker sequentially consult two experts we first show that there is no perfect bayesian equilibrium in which full revelation occurs when both experts are biased in the same direction it is never beneficial to consult both in contrast when experts are biased in opposite directions it is always beneficial to consult both indeed in this case full revelation may be induced in an extended debate by introducing the possibility of rebuttal

learning to cope voluntary financial education and loan performance during a housing crisis as we write this paper at the end of 2009 delinquency and default rates on individual home mortgages have reached unprecedented levels this wave of defaults reflects a vicious combination of a deep recession a burst housing bubble and ill advised financial choices by home borrowers these effects are particularly pronounced among the least creditworthy borrowers many of whom became first time homeowners in the heady days of the bubble this experience prompted calls for increased government intervention in mortgage markets the ensuing policy discussion has centered on two key and not mutually exclusive approaches i tighter oversight of mortgage lenders and products and ii concerted efforts to educate prospective homebuyers to ensure sustainability of their financial commitments the importance of the latter approach has been buoyed by a growing body of research that showed gross inadequacies in financial literacy and the consequential nature of resulting mistakes michelle white 2007 annamaria lusardi 2008 lusardi and olivia mitchell 2008 lusardi and peter tufano 2009 sumit agarwal et al 2010 among others learning to cope voluntary financial education and loan performance during a housing crisis

understanding collaborative consumption an extension of the theory of planned behavior with value based personal norms collaborative consumption is proposed as a potential step beyond unsustainable linear consumption patterns toward more sustainable consumption practices despite mounting interest in the topic little is known about the determinants of this consumer behavior we use an extended theory of planned behavior to examine the relative influence of consumers personal norms and the theory s basic sociopsychological variables attitudes subjective norms and perceived behavioral control on collaborative consumption moreover we use this framework to examine consumers underlying value and belief structure regarding collaborative consumption we measure these aspects for 224 consumers in a survey and then assess their self reported collaborative consumption behavior in a second survey our structural model fits the data well collaborative consumption is more strongly through intentions influenced by personal norms and attitudes than by subjective norms personal norms to consume collaboratively are determined by consumers altruistic biospheric and egoistic value orientations cost savings efficient use of resources and community with others are found to be consumers attitudinal beliefs underlying collaborative consumption we conclude that collaborative consumption can be pin pointed neither as a mere form of economic exchange nor as a primarily normative form of sharing resources instead collaborative consumption is determined by economic egoistic e g cost savings and normative e g altruistic and biospheric value orientations motives implications for collaborative consumption research the theory of planned behavior and practitioners are discussed

acquiring information through peers we develop an endogenous network formation model in which agents form connections to acquire information our model features complementarity in actions as agents care not only about accuracy of their decision making but also about the actions of other agents in equilibrium the information structure is a hierarchical network and under weakly convex cost of forming links the equilibrium network is core periphery although agents are ex ante identical there is ex post heterogeneity in payoffs and actions

institutionalisation of sustainable consumption patterns based on shared use the product service system pss concept has been proposed as a way of dealing with unsustainable patterns of consumption in the business to consumer b2c domain existing alternatives to traditional consumption based on ownership such as car sharing communal washing centres and tool sharing schemes indicate that more sustainable patterns of consumption may be found for other household functions however the low profile of these examples in society and on the market calls for a query into factors that may facilitate or hinder broader acceptance of more sustainable alternatives in this study the aforementioned examples are analysed from institutional and product service system perspectives and it is suggested that the embodiment of alternative consumption patterns into every day routines depends on institutional arrangements regulatory and normative on how the product service systems are designed and applied in practice and oil the socio cultural background of the society the systems are implemented in c 2004 elsevier b v all rights reserved less

planning and financial literacy how do women fare many older us households have done little or no planning for retirement and there is a substantial population that seems to undersave for retirement of particular concern is the relative position of older women who are more vulnerable to old age poverty due to their longer longevity this paper uses data from a special module we devised on planning and financial literacy in the 2004 health and retirement study it shows that women display much lower levels of financial literacy than the older population as a whole in addition women who are less financially literate are also less likely to plan for retirement and be successful planners these findings have important implications for policy and for programs aimed at fostering financial security at older ages

cheap talk with two audiences these problems have in common a simple structure an informed sender says something to two interested but uninformed receivers who then take actions based on their beliefs these actions affect the sender as well as the receivers in this paper we study how costless nonverifiable claims cheap talk can affect these beliefs and hence the actions and how the incentives for truthful revelation to one receiver are affected by the presence of the other we then ask how welfare is affected by whether claims are made in public or in private as some of the above examples suggest public messages may be more credible than private messages addressed to either audience one possibility is that the presence of one audience can discipline the sender s relationship with the other we call this one sided

sharing sustainability how values and ethics matter in consumers adoption of public bicycle sharing scheme this study investigates the antecedents and mechanisms of consumers adoption of a public bicycle sharing scheme pbss as a form of shared sustainable consumption drawing on marketing ethics and sustainability literature it argues that cultural and consumption values drive or deter the adoption of pbss through the mediating mechanism of ethical evaluation this study tests its hypotheses using a sample of 755 consumers from one of the largest pbss programs in china the results confirm the significance of collectivism man nature orientation materialism and face consciousness as key determinants of the adoption of pbss interestingly these values play mixed roles in influencing pbss adoption it also finds that such values and beliefs need to be effectively translated into ethical evaluations of pbss adoption and need to be addressed in the specific social context thus ethical evaluation constitutes a cognitive strategy that allows consumers to justify and defend their adoption of sustainability practices the results suggest that a desirable sustainability program needs to not only cater to the cultural and psychological motivations of consumers but also reflect the social norms and social context in which the sustainability practices and consumers are embedded

strategic communication networks in this paper we consider situations in which individuals want to choose an action close to others actions as well as close to a payoff relevant state of nature with the ideal proximity to the common state varying across the agents before this coordination game with heterogeneous preferences is played a cheap talk communication stage is offered to players who decide to whom they reveal the private information they hold about the state the strategic information transmission taking place in the communication stage is characterized by a strategic communication network we provide a direct link between players preferences and the strategic communication network emerging at equilibrium depending on the strength of the coordination motive and the prior information structure equilibrium strategic communication networks are characterized in a very tractable way and compared in term of efficiency in general a maximal strategic communication network may not exist and communication networks cannot be ordered in the sense of pareto however expected social welfare always increases when the communication network expands strategic information transmission can be improved when group or public communication is allowed and or when information is certifiable

rational inattention and organizational focus this paper studies optimal communication flows in organizations a production process can be coordinated ex ante by letting agents stick to a prespecified plan of action alternatively agents may adapt to task specific shocks in which case tasks must be coordinated ex post using communication when attention is scarce an optimal organization coordinates only a few tasks ex post those tasks are higher performing more adaptive to the environment and influential hence scarce attention requires setting priorities not just local optimization our results provide microfoundations for a central idea in the management literature that firms should focus on a limited set of core competencies

language and the theory of the firm we characterize efficient technical languages and study their interaction with the scope and structure of organizations efficient languages use precise words for frequent events and vague words for unusual ones a broader organizational scope allows for more synergies to be captured but reduces within unit efficiency since it requires a more generic language a manager working as specialized translator may also be used to achieve between unit coordination while maintaining separate languages our theory reconciles two recent well documented phenomena within organizations the recent increase in information centralization and the reduction in hierarchical centralization

the economics of career concerns part ii application to missions and accountability of government agencies the paper uses a simple multitask career concern model in order to analyse the incentives of government agencies officials incentives are impaired by the agency pursuing multiple missions a lack of focus is even more problematic in the case of fuzzy missions that is when outsiders are uncertain about the exact nature of the missions actually pursued by the agency consequently agencies pursuing multiple missions receive less autonomy the paper further shows that professionalization creates a sense of mission for the agency and that the specialization of officials raises their incentives last the paper compares its predictions with the stylized facts on government bureaucracies 1999 the review of economic studies limited

when does coordination require centralization this paper compares centralized and decentralized coordination when manag ers are privately informed and communicate strategically we consider a multi divisional organization in which decisions must be adapted to local conditions but also coordinated with each other information about local conditions is dispersed and held by self interested division managers who communicate via cheap talk the only available formal mechanism is the allocation of decision rights we show that a higher need for coordination improves horizontal com

how national culture and ethics matter in consumers green consumption values abstract going green in consumption is gaining momentum globally but little is known how national cultural values and consumers ethical ideologies explain green consumption with a culturally rich sample of 1929 responses from consumers in finland germany portugal and the united kingdom the present study examines how cultural long term orientation and collectivism predict consumers green consumption values and if these relationships are moderated by ethical ideologies the study finds that cultural collectivism has a significant positive effect on green consumption values as expected however the results show that the two long term orientation constructs namely planning and tradition point in opposite directions when predicting green consumption we demonstrate that while long term planning has a significant positive effect on green consumption values the effect of traditional values is negative we further show that this negative effect varies across consumers ethical ideologies so that the effect is the greatest for exceptionists and absolutists that is those who rely in their actions on universal moral principles rather than particular circumstances therefore our research contributes to the literature by providing new evidence for the cultural and ethical aspects in green consumption values furthermore the study suggests that managers pay special attention to the consumers who have high collectivistic and future oriented values to promote environmentally friendly consumption

the firm as a communication network this paper analyzes how organizations can minimize costs of processing and communicating information communication is costly because it takes time for an agent to absorb new information sent by others agents can reduce this time by specializing in the processing of particular types of information when these returns to specialization outweigh costs of communication it is efficient for several agents to collaborate within a firm it is shown that efficient networks involve centralization that individuals delegate tasks to subordinates only if they are overloaded and that the number of transits to the top tends to be equalized across individual information items

financial literacy financial education and downstream financial behaviors policy makers have embraced financial education as a necessary antidote to the increasing complexity of consumers financial decisions over the last generation we conduct a meta analysis of the relationship of financial literacy and of financial education to financial behaviors in 168 papers covering 201 prior studies we find that interventions to improve financial literacy explain only 0 1 of the variance in financial behaviors studied with weaker effects in low income samples like other education financial education decays over time even large interventions with many hours of instruction have negligible effects on behavior 20 months or more from the time of intervention correlational studies that measure financial literacy find stronger associations with financial behaviors we conduct three empirical studies and we find that the partial effects of financial literacy diminish dramatically when one controls for psychological traits that have been omitted in prior research or when one uses an instrument for financial literacy to control for omitted variables financial education as studied to date has serious limitations that have been masked by the apparently larger effects in correlational studies we envisage a reduced role for financial education that is not elaborated or acted upon soon afterward we suggest a real but narrower role for just in time financial education tied to specific behaviors it intends to help we conclude with a discussion of the characteristics of behaviors that might affect the policy maker s mix of financial education choice architecture and regulation as tools to help consumer financial behavior this paper was accepted by uri gneezy behavioral economics

movers and shakers most projects in most walks of life require the participation of multiple parties while it is difficult to unite individuals in a common endeavor some people who we call movers and shakers seem able to do it the paper specifically examines moving and shaking of an investment project whose return depends both on its quality and the total capital invested in it we analyze a model with two types of agents managers and investors managers and investors initially form social connections managers then bid to buy control of the project and the winning bidder puts effort into making investors aware of it finally a subset of aware investors are given the chance to invest and they decide whether to do so after receiving private signals of the project s quality we first show that connections are valuable since they make it easier for a manager to move and shake the project i e obtain capital from investors when we endogenize the network we find that while managers are identical ex ante a single manager emerges as most connected he consequently earns a rent in extensions we move away from the assumption of ex ante identical managers to highlight forces that lead one manager or another to become a mover and shaker our theory sheds light on a range of topics including entrepreneurship venture capital and anchor investments

do traditional chinese cultural values nourish a market for pirated cds on one hand chinese consumers are well known for conspicuous consumption and the adoption of luxury products and named brands on the other hand they also have a bad reputation for buying counterfeit products their simultaneous preferences for two contrasting types of product present a paradox that has not been addressed in the literature this study attempts to present an explanation of this paradox by examining the effects of traditional chinese cultural values and consumer values on consumers deontological judgment of pirated cds and the amount of social benefits they perceive they gain from them we interviewed 300 hong kong chinese consumers and found that face consciousness increased materialism and risk aversion thereby producing a favorable deontological judgment of pirated cds face consciousness also has a direct effect on the amount of social benefits perceived in pirated cds both favorable deontological judgment and perceived social benefits contributed to a strong intention to buy pirated cds the results are discussed in a cultural perspective

the competitiveness of joint bidding in multiple units uniform price auctions recent literature on joint bidding in a single unit common value cv auction argues that the inference and precision that emerges from pooling information by joint bidders enhances competition such information pooling mitigates adverse selection and results in more aggressive bidding and may even increase revenue despite the reduction in the number of bidders we analyze here for the first time joint bidding in a simple cv uniform price auction with multi unit demand this introduces an opposite force due to increased monopsony power of the joint bidders called demand reduction dr we show that the pro competitive benefit from joint bidding in single unit auctions does not generalize to a multi unit environment even when dr is disallowed with dr the scope for improved competition is further eroded

communication and coordination in social networks i model people in a coordination game who use a communication network to tell each other their willingness to participate the minimal sufficient networks for coordination can be interpreted as placing people into a hierarchy of social roles or stages initial adopters then followers and so on down to late adopters a communication network helps coordination in exactly two ways by informing each stage about earlier stages and by creating common knowledge within each stage we then consider two examples first we show that low dimensional networks can be better for coordination even though they have far fewer links than high dimensional networks second we show that wide dispersion of insurgents people predisposed toward participation can be good for coordination but too much dispersion can be bad although collective action depends on both social structure and individual incentives these integral aspects have been formalized separately in the fields of social network theory and game theory by considering them together this paper engages the classic question of which structures are conducive to coordination and shows that structure and strategy are related in a mutually interesting way here we consider a coordination game in which each person wants to participate only if others participate social structure is thought of as a communication network by which people tell each other their willingness to participate each person knows whether her neighbours in the network are willing but does not know about anyone else our model is thus a game of incomplete information in which each person given his local knowledge decides whether to participate the main result is a characterization of the minimal sufficient networks for coordination in terms of a hierarchy of social roles or stages initial adopters then followers and so on down to late adopters for example a communication network helps coordination in exactly two ways by informing each stage about earlier stages and by creating common knowledge within each stage we also consider two simple examples first we show that low dimension or strong link networks can be better for coordination even though they have far fewer links than high dimension or weak link networks second we show that wide dispersion of insurgents people predisposed toward participation can be good for coordination but too much dispersion can be bad this paper is built on the assumption that the most basic and common mechanism for coordination is the i ll go if you go mechanism individuals first communicate with each other about their preferences and then each individual chooses whether to participate or not hence a person s participation depends on what he knows about his neighbours it does not depend solely on their participation itself either through learning adaptation or social influence the physical analogies of contagion or diffusion are not

endogenous information acquisition in coordination games in the context of a beauty contest coordination game in which payoffs 1 depend on the quadratic distance of actions from an unobserved state variable and 2 from the average action players choose how much costly attention to pay to vari 3 ous informative signals each signal has an underlying accuracy how precisely it 4 identifies the state and a clarity how easy it is to understand the unique linear 5 equilibrium has interesting properties the signals which receive attention are the 6 clearest available even if they have poor underlying accuracy the number of sig 7 nals observed falls as the complementarity of players actions rises and if actions 8 are more complementary the information endogenously acquired in equilibrium 9 is more public in nature the consequences of rational inattention constraints on 10

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

leadership coordination and corporate culture what is the role of leaders in large organizations we propose a model in which a leader helps to overcome a misalignment of followers incentives that inhibits coordination while adapting the organization to a changing environment good leadership requires vision and special personality traits such as conviction or resoluteness to enhance the credibility of mission statements and to eectively rally agents around them resoluteness allows leaders to overcome

the scope and organization of production firm dynamics over the learning curve i introduce a bayesian learning model of the firm to account for a variety of empirical facts about firms the many tasks the firm can undertake the scope of the firm are informationally related so that the firm can enjoy some economies of scope from information the model predicts changes in firm size and its comovement with firm scope that are broadly consistent with the empirical evidence it also provides an explanation for the limits to the scope of the firm the firm may lack information or it may be costly to communicate the information necessary to undertake many tasks
