durable goods and product obsolescence the issue of product obsolescence is addressed by examining the optimal sales strategy of a monopolist firm that may introduce an improved version of its current product consumers expectations of a forthcoming product lowers the price that they are willing to pay for the current product because of its loss in value due to obsolescence the new product is characterized by consumers increased willingness to pay and by its competitive interaction with the old product these characteristics affect the tradeoff that the firm makes between the cost of waiting for new product sales versus the cost of cannibalizing these sales we analyze the effect of these characteristics of the new product on the firm s optimal sales strategy we consider the various policy measures available to the firm including limiting initial sales in order to lower cannibalization of the new product buying back the earlier version of the product in order to generate greater demand for the new product and announcements of future product introductions we find that for modest levels of product improvement the firm s optimal policy is to phase out sales of the old product while for large improvements a buy back policy is more profitable lastly we find that the firm is better off if it informs consumers whether a new product is forthcoming

conceptualising energy use and energy poverty using a capabilities framework in this article we conceptualise energy use from a capabilities perspective informed by the work of amartya sen martha nussbaum and others following them building on this we suggest a corresponding definition of energy poverty as understood in the capabilities space we argue that such an understanding provides a theoretically coherent means of comprehending the relationship between energy and wellbeing and thus conceptualising energy deprivation that makes sense across settings including both the global north and south a coherence which has previously been lacking at the same time it has the flexibility to be deployed in a way that is sensitive to local contexts understanding energy use in the capabilities space also provides a means for identifying multiple sites of intervention including some areas that are currently largely overlooked we argue that this is advantageous for attempts to address energy poverty in the context of climate change and imperatives for the containment of aggregate energy consumption

evidence on the choice of inventory accounting methods lifo versus fifo in this paper we describe various systematic properties of lifo and fifo firms accounting numbers included are assessments of these properties for firms reported annual numbers and for their as if counterparts obtained by estimating what lifo fifo firms would have reported had they used the fifo lifo inventory method instead our purpose in conducting these assessments is to provide additional evidence on tax and nontax explanations of firms choices of inventory accounting methods in the next subsection we elaborate on these two classes and suggest that the nontax explanations may have attracted adherents partly because existing empirical evidence is not entirely consistent with the tax explanation of lifo fifo choices of inventory accounting methods although data limitations prevent us from performing direct tests of these alternative explanations our empirical results

further evidence on the marginal gains in accuracy of alternative levels of specificity of the producer price indexes in the process of evaluating the reliability of the current cost data required to be disclosed by its statement no 33 fasb 1979 the financial accounting standards board fasb is soliciting empirical evidence on the accuracy of price indexes for estimating the current cost of machinery and equipment see fasb 1983 sunder and waymire 1983 presented some preliminary evidence that the marginal gains in accuracy from increasing the specificity of price indexes utilized as measurement techniques for three approximations of the u s economy were not substantial their hypothetical economies consisted of portfolios of 15 68 and 199 commodities represented by selected price indexes from the two digit three digit and four digit producer price indexes ppi respectively most of the indexes they selected represent inventorytype commodities in the absence of actual price data the sunder and waymire 1983 methodology provides a means to assess only the relative efficiency of various aggregations of the ppi to estimate the current costs of assets

conspicuous consumption and sophisticated thinking consumers purchase conspicuous goods to satisfy not only material needs but also social needs such as prestige in an attempt to meet these social needs producers of conspicuous goods like cars perfumes and watches highlight the exclusivity of their products in this paper we propose a monopoly model of conspicuous consumption using the rational expectations framework and then examine how purchase decisions are affected by the desire for exclusivity and conformity we show that snobs can have an upward sloping demand curve but only in the presence of consumers who are weakly followers laboratory tests lend support for this model prediction and for the rational expectations framework the experimental results suggest that subjects used some degree of sophisticated thinking to arrive at their first period decisions their behavior in the subsequent trials however can be adequately captured by a purely adaptive learning mechanism we discuss the implications of consumer learning for optimal dynamic pricing policy by a monopolist

street crime and street culture a model shows how reputation concerns can support widespread street crime a street culture where the direct incentives for such behavior are weak there are social benefits to street reputations but those benefits are dominated when reputation concerns draw into crime those who obtain no direct gain from it the model matches facts about violent crime that a standard model cannot easily explain including low monetary returns disproportionate victimization of the young and poor and high variance in rates across small distances the model generates novel implications for policy and social science including a negative effect of social capital

research note trading up a strategic analysis of reference group effects reference groups influence product and brand evaluations especially when the product is a publicly consumed luxury good marketers of such luxury goods need to carefully balance two important social forces 1 the desire of leaders to distinguish themselves from followers and 2 the countervailing desire of followers to assimilate with leaders in this paper we examine the theoretical implications of these social forces for firm prices product design and target consumer selection we show that the presence of reference group effects can motivate firms to add costly features which provide limited or no functional benefit to consumers furthermore reference group effects can induce product proliferation on one hand and motivate firms to offer limited editions on the other hand we find that offering a limited edition can increase sales and profits in some cases reference group effects can even lead to a buying frenzy

optimal income tax in the presence of status effects abstract the existence of distortions from individuals competing to attain social status by using consumption signals justifies some measure of income tax as a counter acting distortion the question posed here is whether it also constitutes a reason for a more progressive income tax schedule the answer is found to be broadly negative if progressiveness is interpreted as a more convex tax schedule unless the rich are more concerned with status seeking than the poor on the other hand status seeking makes the optimal tax schedule steeper so that redistribution is increased essentially the analysis of status seeking based on a signaling approach confirms and strengthens the existing view of an optimal tax schedule and can be incorporated into the diamond american economic review 88 1998 83 95 approach

energy justice and the contested petroleum politics of stranded assets policy insights from the yasuni itt initiative in ecuador abstract ecuador s progressive yasuni itt initiative operational 2007 to 2013 would have left almost one billion barrels of crude oil locked in perpetuity beneath one of the most intact and diverse nature reserves on the planet the project attempted to strand these oil assets in order to protect biodiversity respect the territory of indigenous peoples combat climate change and encourage more sustainable economic development the yasuni itt proposal would have had the international community pay ecuador 3 6 billion roughly half the value of the oil found there in exchange for not developing the ishpingo tambococha tiputini itt oilfields funds would have been placed into social and environmental development programs and the promotion of domestic renewable energy instead the project collected only 13 million and succumbed to a series of challenges including limited financing intense political pressure a national commitment to oil and carbon leakage this article summarizes the history benefits and insurmountable obstacles facing the yasuni itt initiative and presents six broader lessons and implications for climate and energy analysts practitioners and policymakers it questions the political viability of and serves as a stark warning against those promoting and advocating policies centered on carbon budgets stranded assets negative emissions and carbon revenue streams

dynamic pricing of new experience goods we develop a dynamic model of experience goods pricing with independent private valuations we show that the optimal paths of sales and prices can be described in terms of a simple dichotomy in a mass market prices are declining over time in a niche market the optimal prices are initially low followed by higher prices that extract surplus from the buyers with a high willingness to pay we consider extensions of the model to integrate elements of social rather than private learning and turnover among buyers

steady state of energy feedbacks and leverages for promoting or preventing sustainable energy system development abstract while energy demand has been growing over the last few decades and is projected to keep expanding the current energy system is pushing biophysical source and sink limits at the same time growing demand for energy globally is associated with an expansion of welfare to avoid undesired environmental and social implications of energy developments in the long run a systemic understanding of the dynamics promoting or preventing sustainable energy development is needed departing from daly s steady state economics theory this study conceptualizes a sustainable energy system using a systems thinking approach efficiency increase the central element of daly s theory defined as the service throughput ratio is put in the center of a conceptual analysis of a sustainable energy system and is carefully scrutinized meadows leverage points concept is used to facilitate an analysis of different policies that aim at promoting sustainable energy system development this study concludes that energy policies always need to be explored as part of the broader causality structure into which they are embedded otherwise their impacts on other variables in the system may be overlooked such as in the case of efficiency increase which is shown to have undesired side effects for the development of a sustainable energy system

conspicuous consumption and race using nationally representative data on consumption we show that blacks and hispanics devote larger shares of their expenditure bundles to visible goods clothing jewelry and cars than do comparable whites these differences exist among virtually all subpopulations are relatively constant over time and are economically large although racial differences in utility preference parameters might account for a portion of these consumption differences we emphasize instead a model of status seeking in which conspicuous consumption is used as a costly indicator of a household s economic position using merged data on race and state level income we demonstrate that a key prediction of the status signaling model that visible consumption should be declining in reference group income is strongly borne out in the data for each racial group moreover we show that accounting for differences in reference group income characteristics explains most of the racial difference in visible consumption

an empirical test of the effect of asset aggregation on valuation accuracy significant increases in the general price level during the past two decades have precipitated an ongoing debate concerning possible inadequacies of financial reports and taxation laws based on historical costs many proposed solutions have centered on various methods of asset valuation two american accounting association committees 1964 and 1966 suggested that direct methods of valuation estimation appraisal market quotation were theoretically preferred but that adjustments by price indices could be used as surrogates regarding the latter however there is some uncertainty about how many price indices should be used in the valuation process some suggest that a number of price indices will be necessary to ensure reasonably accurate valuations arthur andersen co 1979 in contrast others suggest that the use of numerous indices may not significantly improve valuation accuracy boersema 1974 and sunder s 1978 analysis shows that the use of additional indices sometimes results in less accurate valuation the purpose of this paper is to offer empirical evidence concerning the effect of the number of price indices on the accuracy of valuation in section 1 i briefly review prior works that have addressed similar research questions the methodology is described in section 2 followed by the results and analysis in section 3 section 4 contains the limitations and conclusions of the study

the uniqueness of the energy security justice and governance problem this article argues that among all policy fields exhibiting externalities of a global scale energy stands out on four dimensions vertical complexity horizontal complexity higher entailed costs and stronger path dependency these structural attributes are at odds with contemporary key challenges of energy security energy justice and low carbon energy transition with regard to the latter energy governance challenges occur related to unclear levels of authority and weak resilience this has implications for energy scholarship specifically relating to the political economy of energy transitions discussions about common pool resources systems analysis and other neighboring disciplines

pricing of conspicuous goods a competitive analysis of social effects abstract social needs play an important role in the purchase of conspicuous goods in this article the authors extend traditional economic models to accommodate social needs such as desire for uniqueness and conformism and examine their implications for pricing conspicuous goods first in the context of a duopoly the authors identify the conditions under which the desire for uniqueness can increase demand among some consumers as the price of a product increases second the authors show that though the desire for uniqueness leads to higher prices and firm profits a desire for conformity leads to lower prices and profits third the authors find that consumers purchase high quality products not because of their desire for uniqueness but despite it finally marketers of conspicuous goods may find it beneficial not to emphasize the functional differences among their products when the need for uniqueness is high in a laboratory test the authors find support for the claim that demand for a product amo

on limiting the market for status signals abstract in many societies individuals care how others view them in their efforts to impress such individuals engage in consumption signals which attempt to establish higher levels of status than their true status type this leads to an inefficiency which offers the possibility of a pareto improving tax policy the impacts of tax policy and benefits on the signalling equilibrium are considered

conspicuous consumption and dynamic pricing how do firms develop marketing strategy when consumers seek to satisfy both quality and status related considerations we develop an analytical model to study this issue examining both pricing and product management decisions in markets for conspicuous durable goods our analysis yields many interesting and nontrivial insights first we demonstrate that high intrinsic quality indirectly generates exclusivity via pricing effects in turn this exclusivity generates considerable social payoffs where consumers value status this insight reverses the direction of causality in the existing literature wherein only status considerations matter and mere price increases may enhance consumer utility second our dynamic model indicates that where consumers prioritize status benefits producers incur substantial price depreciation in equilibrium third we examine the product management strategies used by firms to preserve early adopter exclusivity finally we discuss the boundary conditions of our results as well as our results implications for managerial and policy issues

design innovation and fashion cycles a model of fashion cycles is developed in which designs are used as a signaling device in a dating game a monopolist periodically creates a new design over time the price of the design falls as it spreads across the population once sufficiently many consumers own the design it is profitable to create a new design and thereby render the old design obsolete this paper gives conditions under which all consumers would be better off by banning the use of fashion competition among designers may lead to less frequent changes in fashion and to higher prices than monopoly copyright 1995 by american economic association

resolving society s energy trilemma through the energy justice metric carbon dioxide emissions continue to increase to the detriment of society in many forms one of the difficulties faced is the imbalance between the competing aims of economics politics and the environment which form the trilemma of energy policy this article advances that this energy trilemma can be resolved through energy justice energy justice develops the debate on energy policy to one that highlights cosmopolitanism progresses thinking beyond economics and incorporates a new futuristic perspective to capture these dynamics of energy justice this research developed an energy justice metric ejm that involves the calculation of several metrics 1 a country national ejm 2 an ejm for different energy infrastructure and 3 an ejm which is incorporated into economic models that derive costs for energy infrastructure projects an ejm is modeled for china the european union and the united states and for different energy infrastructure in the united kingdom the ejm is plotted on a ternary phase diagram which is used in the sciences for analyzing the relationship trilemma of three forms of matter the development of an ejm can provide a tool for decision making on energy policy and one that solves the energy trilemma with a just and equitable approach

limited edition products when and when not to offer them many brands today introduce limited edition le products as part of their product line however little is known about the conditions under which a brand should introduce an le product or the competitive implications of doing so we investigate this issue using a game theoretic model of a market where two brands compete for consumers who desire exclusivity our analysis shows that adding an le product has a positive direct effect on brand profits through the increased willingness of consumers to pay for such a product but also has a negative strategic effect by increasing price competition between brands these effects result in different conclusions depending on the nature of brand differentiation when brands differ in quality we show that only the high quality brand may gain in comparison to a scenario where there are no le products although a low quality brand may offer an le product as a defensive strategy its profits are lower than would be in a world without le products because of the negative strategic effect when we consider brands that are differentiated on a horizontal attribute such as taste we find that the negative strategic effects cause lower equilibrium profits if both brands introduce le products yet brands cannot avoid introducing le products because they face a prisoners dilemma

energy justice at the end of the wire enacting community energy and equity in wales energy justice has emerged as a useful lens for understanding and guiding energy decision making however whilst calls for greater energy justice have grown fleeting attention has been paid to the role and agency of the very people at the heart of this agenda clearly given the increasing prevalence of local energy initiatives such projects warrant more sustained focus both to explore how energy justice is constructed between settings and to prompt greater consideration of its associated outcomes this paper seeks to address this gap by using energy justice to assess local ownership of small scale energy generation through a study of the community energy sector in wales in so doing it aids greater understanding of the energy equity dimension understood in terms of accessibility and affordability of the energy trilemma from a conceptual standpoint the research examines how energy justice is negotiated and contested at community scale through a focus on issues of distributive and procedural justice from a policy standpoint the research shows that community energy is often involved in a wide range of local objectives and directs attention to how best to support such initiatives to further stimulate local action and deliver more widespread equity gains

managing the energy trilemma the case of indonesia abstract this article argues that a central challenge for energy governance is how to manage a complex energy trilemma involving the sometimes competing demands of energy security climate change mitigation and particularly in developing countries energy poverty it suggests that tensions between the horns of the trilemma in large part explain indonesia s current profoundly suboptimal energy policy while these tensions are not inherently incapable of resolution such resolution would require good governance at both state and global levels the possibilities for and obstacles confronting such governance are explored and provisional solutions canvassed

optimal price skimming by a monopolist facing rational consumers this paper considers the intertemporal pricing problem for a monopolist marketing a new product the key feature differentiating this paper from the extant management science literature on intertemporal pricing is the assumption that consumers are intertemporal utility maximizers a subgame perfect nash equilibrium pricing policy is characterized and shown to involve intertemporal price discrimination we compare this policy to the optimal policy for a monopolist facing myopic consumers and find that for any given state prices are always lower with rational consumers than with myopic consumers for plausible parameter values the assumption of consumer rationality can be shown to lead to large differences in optimal prices moreover if a monopolist facing rational consumers implements the optimal myopic consumer pricing policy profits can be significantly less than if the monopolist follows the equilibrium pricing policy for rational consumers

conspicuous consumption snobbism and conformism abstract we develop a model in which consumers purchase a conspicuous good in order to signal high income and thereby achieve greater social status in equilibrium the signalling value of conspicuous consumption depends in an identifiable way on the number of consumers and consumer behaviour is characterized by either snobbism or conformism the market demand curve for the conspicuous good may exhibit a positive slope if consumers are conformist we derive some unconventional policy implications concerning the taxation of luxuries and the voluntary provision of public goods

entry of copycats of luxury brands we develop a game theoretic model to examine the entry of copycats and its implications by incorporating two salient features these features are two product attributes i e physical resemblance and product quality and two consumer utilities i e consumption utility and status utility our equilibrium analysis suggests that copycats with a high physical resemblance but low product quality are more likely to successfully enter the market by defying the deterrence of the incumbent furthermore we show that higher quality can prevent the copycat from successfully entering the market finally we show that the entry of copycats does not always improve consumer surplus and social welfare in particular when the quality of the copycat is sufficiently low the loss in status utility from consumers of the incumbent product overshadows the small gain in consumption utility from buyers of the copycat leading to an overall decrease in consumer surplus and social welfare

consumer choice between hedonic and utilitarian goods abstract in this article the authors examine how consumer choice between hedonic and utilitarian goods is influenced by the nature of the decision task building on research on elaboration the authors propose that the relative salience of hedonic dimensions is greater when consumers decide which of several items to give up forfeiture choices than when they decide which item to acquire acquisition choices the resulting hypothesis that a hedonic item is relatively preferred over the same utilitarian item in forfeiture choices than in acquisition choices was supported in two choice experiments in a subsequent experiment these findings were extended to hypothetical choices in which the acquisition and forfeiture conditions were created by manipulating initial attribute level reference states instead of ownership finally consistent with the experimental findings a field survey showed that relative to market prices owners of relatively hedonic cars value their vehicles more than do owners of relat

accuracy of linear valuation rules in industry segmented environments industry vs economy weighted indexes abstract the comparative ability of valuation rules using economy weighted versus industry weighted price indexes to estimate the unobserved economic value of a basket of assets in modelled industry weighted indexes do not necessarily provide valuations of higher accuracy than economy weighted indexes dominance depends on 1 the relative magnitude of the mean and variability of price changes and 2 the magnitude of errors of measurement in the current price data larger measurement errors favor economy weighted indexes larger mean and variability of prices changes favor industry weighted indexes

veblen effects in a theory of conspicuous consumption the authors examine conditions under which veblen effects arise from the desire to achieve social status by signaling wealth through conspicuous consumption while veblen effects cannot ordinarily arise when preferences satisfy a single crossing property they may emerge when this property fails in that case budget brands are priced at marginal cost while luxury brands though not intrinsically superior are sold at higher prices to consumers seeking to advertise wealth luxury brands earn strictly positive profits under conditions that would with standard formulations of preferences yield marginal cost pricing the authors explore factors that induce veblen effects and they investigate policy implications copyright 1996 by american economic association

stock price effects of the allowance of lifo for tax purposes abstract i investigate stock price behavior associated with the allowance of lifo for tax purposes the analysis is structured as an event study of the revenue acts of 1938 and 1939 the results indicate a positive net market reaction to legislative events leading to lifo s incorporation into the us tax code for the sample firms having the largest estimated lifo tax benefits i conclude the market revised its probabilities that firms most likely to benefit would avail themselves of the opportunity to use lifo and defer taxes on inventory profits

getting ahead of the joneses when equality increases conspicuous consumption among bottom tier consumers it is widely believed that increasing the equality of material possessions or income in a social group should lead people at the bottom of the distribution to consume less and save more however this prediction and its causal mechanism have never been studied experimentally five studies show that greater equality increases the satisfaction of those in the lowest tier of the distribution because it reduces the possession gap between what they have and what others have however greater equality also increases the position gains derived from status enhancing consumption since it allows low tier consumers to get ahead of the higher proportion of consumers clustered in the middle tiers as a result greater equality reduces consumption when consumers focus on the narrower possession gap but it increases consumption when they focus on the greater position gains i e when consumption is conspicuous social competition goals are primed and the environment is competitive
