an experimental investigation of the hahn noll revenue neutral auction for emissions licenses abstract this paper reports on three series of laboratory experiments designed to test the performance of the hahn noll revenue neutral auction rna an alternative institution a no rebate uniform price auction upa is also examined as a benchmark in these experiments the rna markets were little different from upa markets in terms of either prices or market efficiencies the two institutions did differ in terms of the distribution of the gains from exchange and of the propensity of bidders to engage in a certain type of overbidding

perishable inventory theory a review this paper reviews the relevant literature on the problem of determining suitable ordering policies for both fixed life perishable inventory and inventory subject to continuous exponential decay we consider both deterministic and stochastic demand for single and multiple products both optimal and sub optimal order policies are discussed in addition a brief review of the application of these models to blood bank management is included the review concludes with a discussion of some of the interesting open research questions in the area

the non monetary nature of gifts this paper addresses the prevalence of non monetary gifts over more highly valued and e cient monetary transfers in social relationships we demonstrate that under a wide variety of circumstances ine cient non monetary gifts will be o ered by a donor in lieu of cash in order to signal the donor s quality of information about the recipient s preferences this result emerges because gift giving is ine cient relative to cash and not because of any arbitrary assumptions regarding communication in particular the donor has available the strategy of o ering cash and saying what he would have purchased nonetheless there is still an important equilibrium role for buying gifts 2001 elsevier science b v all rights reserved jel classixcation a13 d10 d64 d82 z1

gift giving and the evolution of cooperation gift giving is a practice common to many societies in an evolutionary model the social custom of giving gifts at the beginning of a relationship can lead to trust and cooperation the evolutionary approach makes predictions about the character of the goods that can be used as gifts for example gift goods may have little use value even at low levels of consumption although the gifts themselves are useless the institution is not

why do people volunteer an experimental analysis of preferences for time donations why do individuals volunteer their time even when recipients receive far less value than the donor s opportunity cost previous models of altruism that focus on the overall impact of a gift cannot rationalize this behavior despite its prevalence we develop a model that allows for differential warm glow depending on the form of the donation in a series of laboratory experiments that control for other aspects of volunteering such as its signaling value subjects demonstrate behavior consistent with the theoretical assumption that gifts of time produce greater utility than the same transfers in the form of money subjects perform an effort task accruing earnings at potentially different wage rates for themselves or a charity of their choice with the ability to transfer any of their personal earnings to charity at the end of the experiment subjects exhibit strong preferences for donating time even when differential wage rates make it costly to do so the results provide new insights on the nature of vo

does consumer irrationality trump consumer sovereignty scholars working on the border of economics and psychology have documented many contexts in which individual decision making is unreliable and might be improved by paternalistic interventions against this mounting body of negative evidence economists default belief in consumer sovereignty has been motivated primarily by theory rather than evidence the goal of the present study is to see whether there is direct evidence supporting economists faith in consumer sovereignty in a simple context we address this question by presenting direct evidence that consumers own purchases generate between 10 and 18 more value per dollar spent than items received as gifts

the deadweight loss of christmas reply we welcome bradley j ruffle and orit tykocinski s 1999 attempt to reconcile the difference in findings between our paper solnick and hemenway 1996 and joel waldfogel s 1993 in both studies subjects were asked to estimate the cost and the value to them of gifts they had received waldfogel found that gift recipients typically valued their gifts at only 87 percent of their estimated cost to the givers by contrast our sample of adults from train stations and airports and from faculty staff and graduate students at harvard reported valuing their gifts at more than twice the estimated cost ruffle and tykocinski examine the wording of the question used to elicit the valuation of the gift waldfogel s subjects were economics students hence he could ask them directly what amount of cash would make them indifferent between the gift and a cash alternative since we wanted to question people without economics training we asked respondents to name the amount of money that would make them equally happy as receiving the gift ruffle and tykocinski find that the change from waldfogel s wording to ours results in a 15to 20 percent increase in estimated value while leaving accompanying cost estimates unchanged the wording of the question clearly matters but to pose a question that only those with training in economics can answer limits the scope of inquiry in the study by ruffle and tykocinski 10 percent of the psychology students raised their hands to ask for a definition of indifferent we wonder how this concept was explained to them what those who asked and those who did not ask made of the term and what set of emotions might have been activated had waldfogel used our question rather than finding any deadweight loss a yield of 87 percent he would have reported gifts being valued very close to cost 100 0 or 104 4 percent thus ruffle and tykocinski take us partway towards an understanding of the difference in our findings and waldfogel s yet a wide gulf remains ruffle and tykocinski reject our claim that sample selection may be largely responsible for the difference between our results and waldfogel s it does appear that results do not vary a great deal with the type of undergraduate questioned whether a student is enrolled in a psychology or an economics class or in a more or less prestigious institution but the real issue of sample selection has not been adequately addressed ours remains the only study to use adults living independently as subjects we note that ruffle and tykocinski s subjects performed poorly in estimating costs for example psychology students estimated the cost of the mask at 603 shekels and economics students at 375 shekels actual retail price was 800 shekels this incidental finding supports our belief that college students may not be full fledged participants in many market or gift exchange processes it is certainly possible that the average gain in gift exchange may be lower than the 214 percent measured in our survey but we remain convinced that even examining solely the material value to the recipient gift giving can and often does result in a gain rather than a deadweight loss

zero as a special price the true value of free products when faced with a choice of selecting one of several available products or possibly buying nothing according to standard theoretical perspectives people will choose the option with the highest cost benefit difference however we propose that decisions about free zero price products differ in that people do not simply subtract costs from benefits but instead they perceive the benefits associated with free products as higher we test this proposal by contrasting demand for two products across conditions that maintain the price difference between the goods but vary the prices such that the cheaper good in the set is priced at either a low positive or zero price in contrast with a standard cost benefit perspective in the zero price condition dramatically more participants choose the cheaper option whereas dramatically fewer participants choose the more expensive option thus people appear to act as if zero pricing of a good not only decreases its cost but also adds to its benefits after documenting this basic effect we propose and test several psychological antecedents of the effect including social norms mapping difficulty and affect affect emerges as the most likely account for the effect

is everything neutral in his well known analysis of the national debt robert barro introduced the notion of a dynastic family this notion has since become a standard research tool particularly in the areas of public finance and macroeconomics in this paper we critique the assumptions on which the dynastic model is predicated and argue that this framework is not a suitable abstraction in contexts in which the objective is to analyze the effects of public policies we reach this conclusion by formally considering a world in which each generation consists of a large number of distinct individuals as opposed to one representative individual we point out that family linkages form complex networks in which each individual may belong to many dynastic groupings the resulting proliferation of linkages between families gives rise to a host of neutrality results including the irrelevance of all public redistributions distortionary taxes and prices since these results are not at all descriptive of the real world we conclude

incentive aligned conjoint analysis abstract because most conjoint studies are conducted in hypothetical situations with no consumption consequences for the participants the extent to which the studies are able to uncover true consumer preference structures is questionable experimental economics literature with its emphasis on incentive alignment and hypothetical bias suggests that more realistic incentive aligned studies result in stronger out of sample predictive performance of actual purchase behaviors and provide better estimates of consumer preference structures than do hypothetical studies to test this hypothesis the authors design an experiment with conventional hypothetical conditions and parallel incentive aligned counterparts using chinese dinner specials as the context the authors conduct a field experiment in a chinese restaurant during dinnertime the results provide strong evidence in favor of incentive aligned choice conjoint analysis in that incentive aligned choice conjoint outperforms hypothetical choice conjo

an optimal ordering and issuing policy for a two stage inventory system for perishable products this paper considers the problem of ordering and issuing policies arising in controlling finite life time fresh meat carcass inventories in supermarkets a supermarket orders a product which constitutes a set of sub products of fixed proportion from a vendor at the beginning of each time cycle after it is received from the vendor the product is stored in the cool room before being issued to the display shelves the sub products then satisfy random customer demand after passing the life time sub products are salvaged in this system the sub products are issued to the display shelves according to theorder up to level policies at the beginning of every period the decisions to be taken to solve this problem are the product ordering quantity from the outside vendor and the order up to issuing quantities for each sub product the objective function to be maximized is the expected profit per unit time consisting of revenue from sales and salvage and the cost of ordering processing or issuing inventory holding emergency issuing and shortage in this paper we first develop a mathematical model describing actual operations and then simplify the sub product runout period so that optimal ordering and issuing policies are easily established we then carry out extensive numerical experiments for a case of two sub products in order to ascertain the properties and the behavior of the optimal solutions

entrepreneurship social mobility and income redistribution in south india development economists have been preoccupied with the problem of increasing the size of the gnp pie to the relative neglect of its distribution despite the recent disenchantment with the viewpoint that all classes share in the benefits of industrial growth empirical data on the distribution of income business opportunity and economic power are in short supply many of the studies on entrepreneurship and economic development when they are not apologetics for ruthless capitalist exploitation as paul baran suggests extol the achievements of the capitalist entrepreneur without examining class origins and monopoly advantage joseph schumpeter sees entrepreneurs irrespective of class origin as heroic figures with the dream and will to found a private kingdom to conquer adversity to achieve success for its own sake and to experience the joy of creation for gustav papanek 1967 the private entrepreneur who is frugal diligent far sighted remarkably able and willing to take political risks is in large part responsible for the success of pakistan in achieving rapid industrialization

from constraint to sufficiency the decoupling of energy and carbon from human needs 1975 2005 abstract we investigate the relationship between human needs energy consumption and carbon emissions for several indicators of human development life expectancy literacy income and the human development index we find that high human development can be achieved at moderate energy and carbon levels increasing energy and carbon past this level does not necessarily contribute to higher living standards by conducting a novel longitudinal analysis from 1975 to 2005 we observe a previously undetected decoupling of the per capita energy and carbon required for human needs if resources were equally distributed current energy and carbon levels would be more than sufficient to satisfy global human needs at high levels of human development by projecting current trends to 2030 we demonstrate that the global energy consumption and carbon emissions required to satisfy human needs will decrease with time despite growth in population

understanding the role of energy consumption in human development through the use of saturation phenomena a correlation is presented between the un human development index and per capita energy consumption for 120 nations a strong relationship between index values and energy consumption is observed for the majority of the world additionally a distinct secondary trend emerges from the dataset representing heavy energy exporters such as the organization of the petroleum exporting countries and some former soviet union nations among others the preliminary observation is made that these two trends closely resemble saturation curves exhibited by a variety of natural phenomena for the primary trend three regions are isolated a steep rise in human development relative to energy consumption for energy poor nations a moderate rise for transitioning nations and essentially no rise in human development for energy advantaged nations consuming large amounts of modern energy these correlations suggest that tremendous gains in human development are possible for the world s poorest with small incremental access to energy

gains from digitization evidence from gift giving in music abstract in this paper we focus on recorded music gifts during the holiday season and estimate the reduction in deadweight loss due to the transition from physical cd gift giving to digital music gift giving with gift cards based on our survey data we find that music cd gifts generate an average deadweight loss between 15 and 38 of the price according to our estimates of gift music album sales which are based on u s data the welfare gains from digitization in terms of eliminated deadweight loss as a percentage of total spending on music albums were between 5 and 13 during the week when digital sales peak in 2014

review of inventory systems with deterioration since 2001 abstract this paper presents an up to date review of the advances made in the field of inventory control of perishable items deteriorating inventory the last extensive review on this topic dates back to 2001 goyal s k and giri b c recent trends in modeling of deteriorating inventory european journal of operational research 134 1 16 since then over two hundred articles on this subject have been published in the major journals on inventory control indicating the need for a new review we use the classification of goyal and giri based on shelf life characteristics and demand characteristics contributions are highlighted by discussing main system characteristics including price discounts backordering or lost sales single or multiple items one or two warehouses single or multi echelon average cost or discounted cash flow and payment delay

markets gift cards the mobil oil company introduced the first retail gift card that recorded value on a magnetic strip in 1995 in under a decade such gift cards replaced apparel as the number one item sold during the christmas season this study will discuss the reasons for the strong surge in the gift card market it will then consider the value of gift cards as an intermediate option between two alternatives purchasing a physical gift which could possibly be returned or exchanged versus giving cash empirical data on the resale price of gift cards from an internet auction website provide information on the value that recipients place on gift cards suggesting that the difference between the cost of a gift card to the giver and its value to the recipient is substantial although perhaps not quite as large as the parallel gap involved in physical gifts

on the income dependence of equivalence scales household consumption exhibits economies of scale as the number of household members increases we collect survey data from two countries germany and france in order to obtain direct subjective estimates of household consumption economies of scale and in particular to examine an additional dimension whether household consumption economies of scale change as living standards go up our data from both countries indicate strongly that household economies of scale increase as the living standard goes up we discuss the robustness of our survey method and compare our results to these of alternative estimation methods in the literature

what experimental protocol influence disparities between actual and hypothetical stated values preferences elicited in hypothetical settings have recently come underscrutiny causing estimates from the contingent valuation method to bechallenged due to perceived hypothetical bias given that the receivedliterature derives value estimates using heterogeneous experimentaltechniques understanding the effects of important design parameters onthe magnitude of hypothetical bias is invaluable in this paper we addressthis issue statistically by using a meta analysis to examine data from 29experimental studies our empirical findings suggest that on averagesubjects overstate their preferences by a factor of about 3 in hypotheticalsettings and that the degree of over revelation is influenced by thedistinction between willingness to pay and willingness to accept publicversus private goods and several elicitation methods

the deadweight loss of christmas comment two previous surveys used to measure the welfare implications of christmas gift giving in the united states have reached opposite conclusions joel waldfogel 1993 finds a welfare reduction of 13 percent or more associated with christmas giving curiously sara j solnick and david hemenway s 1996 henceforth sh replication of waldfogel s survey turns up just the opposite result a 214 percent welfare gain we design a series of controlled laboratory experiments to determine why the two papers arrive at opposite conclusions we do not produce our own estimate of the deadweight loss of gift giving rather our aim is to understand how and which among the differences in methodology between the two studies account for their divergent findings waldfogel 1993 surveyed 58 students enrolled in an intermediate microeconomics class about specific gifts they had received for christmas he asked recipients to estimate the amount paid by the giver for each gift received recipients were then asked to place a value on each gift they received respondents were instructed to estimate the value of a gift as the amount of cash such that you are indifferent between the gift and the cash not counting the sentimental value of the gift p 1331 waldfogel measures the welfare yield of a gift as the difference between the recipient s valuation and her cost estimate of the gift based on 278 gifts reported waldfogel finds that gifts have an average yield of 87 1 percent indicating that gifts lose about 13 percent of their value in the exchange from giver to receiver when cash gifts are excluded the average yield falls further to 83 9 percent sh were intrigued enough by waldfogel s results to replicate his study contrary to waldfogel sh find that gift giving is actually welfare improving with an average yield of 214 percent median yield 111 percent they claim that a broader subject pool than that questioned by waldfogel explains the reversal concerned that undergraduates in an intermediate microeconomics class may be unrepresentative sh administered their survey to members of the general public at train stations and airports and to staff and graduate students enrolled in a biostatistics or an economics class at the harvard school of public health they also altered the question used to elicit respondents valuations of gifts received their survey question reads as follows p 1300 aside from any sentimental value if without the giver ever knowing you could receive an amount of money instead of the gift what is the minimum amount of money that would make you equally happy the change in wording from the amount of cash such that you are indifferent to the amount of money that would make you equally happy was prompted by a concern that indifference is a technical word familiar only to economists it remains to be seen whether sh s equally happy question is substantially equivalent to the indifference version of the question or whether they have introduced a greater change than they realize an additional methodological concern is that the cost estimates always precede respondents valuations in both studies order effects are well documented in the social psychology literature cost estimates may influence valuations in particular costs may serve as a judgmental anchor upon which to base value estimates reversing the order of the questions is a technique common to survey and experimental methods in the social sciences to balance the researcher s design and offset possible order effects ruffle department of economics ben gurion university p o b 653 beer sheva 84105 israel e mail bradley bgumail bgu ac il tykocinski department of behavioral sciences ben gurion university beer sheva 84105 israel e mail oritt bgumail bgu ac il we thank tomer bakalash for research assistance and sara solnick todd kaplan three anonymous referees of this journal and seminar participants at ben gurion university universite louis pasteur and the 1998 esa meetings in mannheim for comments 1 howard schuman and stanley presser 1981 provide a good starting point in this literature

information sharing and order variability control under a generalized demand model the value of information sharing and how it could address the bullwhip effect have been the subject of studies in the literature most of these studies used different forms of demand models assuming that no order smoothing was used by the retailer and that the supplier has full knowledge of the retailer s demand model and order policy in this paper we contribute to the literature by starting with a most general demand model coupled with a smoothing policy for order variability control in addition we do not require that the supplier has full knowledge of the retailer s demand model and order policy but instead let the retailer share its projected future orders and freely revise them as the retailer sees fit under such a setting we first obtain a unifying formula for the magnitude of the bullwhip effect the formula indicates that it is the forecast correlation over the exposure period as a whole that determines the magnitude of the bullwhip effect we then quantify the value of information sharing and generalize the existing results in the literature finally we explore the optimal smoothing parameters that could benefit the total supply chain the resulting optimal policy resembles the postponement strategy we find that information sharing together with order postponement improves the supply chain performance even though the order variability may amplify in some cases

gifts as economic signals and social symbols gift giving has often puzzled economists especially because efficient gifts like cash or giving exactly what a person asks for seem crass or inappropriate it is shown in a formal game theoretic model that gifts serve as signals of a person s intentions about future investment in a relationship and inefficient gifts can be better signals other explanations for the inefficiency of gift giving are advanced and some stylized facts about gift giving practices are described many of which are consistent with the signaling view of gifts

bidding behavior and decision costs in field experiments i introduction positive opportunity costs of mental effort may invalidate the predictions of traditional models of rational or hyperrational agents conlisk 1996 uses deliberation costs as a recurring theme when discussing four important reasons for incorporating bounded rationality in economic models smith and walker 1993 and smith and szidarovszky 1999 present effort models that predict individual behavior will more closely match the predictions of rational behavior theories as 1 the stakes of the decision increase and 2 the decision costs decrease smith and walker 1993 find evidence of these two effects in a comprehensive review of 31 published laboratory experiments camerer and hogarth 1999 extend smith and walker s survey by examining 74 experimental papers and find evidence in favor of the cognitive effort theory noting that higher levels of incentives have the largest effects in judgment and decision tasks p 34 although the laboratory evidence is compelling there has been little verificati on of these predictions outside the laboratory 1 the present article fills this gap by examining field data from 214 multiunit sports card auctions carried out in an active marketplace on the floor of a sports card show we auctioned four types of trading cards with book values ranging from 3 to 70 providing significant variation in the stakes of the auction our auctions also included two distinct types of subjects some auctions had sports card dealers bidding against each other whereas others had individual card collectors as the participants this variation allows us to explore the second dimension of decision cost theory do dealers who commonly participate in sports card auctions and therefore likely require less effort to bid optimally bid more rationally than nondealers our measure of rational bidding comes from multiunit auction theory which predicts strategic demand reduction in uniform price auctions 2 for each type of bidder and each type of card we measure this demand reduction behavior in the uniform price auction relative to a control the multiunit vickrey 1961 auction where bidders are predicted to fully reveal their demands our sports card data generated from sales of 428 cards with a combined book value of nearly 10 000 provide two major insights first we find that the predicted strategic behavior is considerably greater when the auctioned cards have higher values second dealers exhibit more of the predicted strategic behavior than do nondealers for both lower and higher priced cards one conjecture to explain this finding is that nondealers may find that the cognitive effort required to bid strategically exceeds the benefits especially for low valued cards by contrast dealers have more experience with auctions and make their living by buying selling trading cards so their cognitive costs are likely much lower than those of nondealers these two findings are consistent with recent theoretical models of monetary rewards and decision costs and extend previous experimental evidence from the laboratory into the field ii experimental design as mentioned recent theoretical literature has suggested that demand reduction inherent in uniform price auctions with multiunit demand can induce inefficient allocations and possible reductions in auction revenue to avoid the inefficiencies associated with the uniform price auction theorists have identified an alternative mechanism the generalized vickrey auction which gives bidders a dominant strategy of revealing their true valuations for all units of the good in this multiunit vickrey auction as in the uniform price auction each bidder can submit up to n different sealed bids on individual units and the highest n bids are declared winners if a bidder submits one or more of the winning bids his or her price for the first unit equals the highest rejected bid submitted by someone else and his or her price for the kth unit equals the kth highest of the rejected bids submitted by others

substitutability experience and the value disparity evidence from the marketplace abstract recent empirical evidence suggests that important disparities exist between willingness to pay and compensation demanded for the same good these results which clearly contradict closely held economic doctrines have led some influential commentators to call for an entirely new economic paradigm to displace conventional neoclassical theory this study examines the generality of these experimental findings by going to a well functioning marketplace and examining more than 350 individual decisions across two incentive compatible elicitation mechanisms the data suggest that behavior of individuals with intense experience approaches neoclassical predictions any observed wta wtp disparity amongst this group is negligible

information distortion in a supply chain the bullwhip effect this article originally appeared in management science april 1997 volume 43 number 4 pp 546 558 published by the institute of management sciences consider a series of companies in a supply chain each of whom orders from its immediate upstream member in this setting inbound orders from a downstream member serve as a valuable informational input to upstream production and inventory decisions this paper claims that the information transferred in the form of orders tends to be distorted and can misguide upstream members in their inventory and production decisions in particular the variance of orders may be larger than that of sales and distortion tends to increase as one moves upstream a phenomenon termed bullwhip effect this paper analyzes four sources of the bullwhip effect demand signal processing rationing game order batching and price variations actions that can be taken to mitigate the detrimental impact of this distortion are also discussed

retrospectives consumer sovereignty the term consumer sovereignty is usually traced to william harold hutt and his 1936 book economists and the public a study of competition and opinion hutt paid only passing attention to the maximization of consumer welfare or the achievement of market efficiency he was stalking different game for him the basic issues revolved around the exercise of power in a free society and those issues concerned sovereignty why should consumers be given such great power in determining the allocation of resources and the course of production hutt s major argument for consumer sovereignty centered on its role in promoting political and social stability it is unlikely that hutt s defense of consumer sovereignty will be embraced by the economics profession in the near future it received only passing attention when first propounded and has largely disappeared from active discussion yet i would argue that his approach has a most interesting message

an allocation and distribution model for perishable products this paper presents an allocation model for a perishable product distributed from a regional center to a given set of locations with random demands we consider the combined problem of allocating the available inventory at the center while deciding how these deliveries should be performed two types of delivery patterns are analyzed the first pattern assumes that all demand points receive individual deliveries the second pattern subsumes the frequently occurring case in which deliveries are combined in multistop routes traveled by a fleet of vehicles computational experience is reported

the bullwhip effect progress trends and directions the bullwhip effect refers to the phenomenon where order variability increases as the orders move upstream in the supply chain this paper provides a review of the bullwhip literature which adopts empirical experimental and analytical methodologies early econometric evidence of bullwhip is highlighted findings from empirical and experimental research are compared with analytical and simulation results assumptions and approximations for modelling the bullwhip effect in terms of demand forecast delay replenishment policy and coordination strategy are considered we identify recent research trends and future research directions concerned with supply chain structure product type price competition and sustainability

order variability in perishable product supply chains abstract empirical research has shown that the degree of order variability in supply chains is significantly influenced by product and industry specific factors this paper analyzes the impact of perishability on order variability and the bullwhip effect in supply chains we decompose the ordering process of a retailer into a sales and an outdating process and quantify their short and long term variability and correlation we find differences to non perishable product supply chains driven by the impact of the inventory depletion policy stock out management and retailers service level requirement these three factors significantly affect the retailer s order variability and thus the decision making process and the profitability of the upstream supply stage for the majority of instances the perishable nature of a product results in the ordering process having a lower variability than the demand process only when inventory depletion is dominated by last in first out in high service level environments variability amplification can be observed we propose a dynamic ordering policy for the upstream supply stage taking into account negative correlation of retailer orders between periods this dynamic policy may lead to substantial performance improvements in a sensitivity analysis we investigate the impact of shelf life lead time and demand correlation

in search of welfare improving gifts gift giving is thought to decrease welfare recipients are sometimes stuck with gifts they would not have purchased because the giver does not perfectly know the recipient s preferences and in kind gifts cannot be costlessly refunded such gifts are welfare reducing compared to giving cash if in addition recipients possess full information as to which stores carry their desired goods and the ability to reach these stores costlessly we replace these two latter assumptions with the more realistic assumptions of uncertainty about the location of goods and search costs in contrast to existing economic models gifts in our model enhance expected welfare moreover gift giving cannot be replaced by a profit maximizing trader nor the introduction of nearby specialty stores carrying gift goods we use our model to explain a number of stylized facts about gift giving the organization of retail trade and in kind government transfers 2008 elsevier b v all rights reserved

forced gifts the burden of being a friend abstract in many developing countries gift expenses escalate with income growth and account for a substantial share of household expenditure we develop a theoretical model to demonstrate how unequal income growth may trigger gift competition and drive up the financial burden associated with gift exchange we use unique census type panel data from rural china to test our model predictions and demonstrate that 1 the value of gifts responds to the average gift in the community 2 the escalation of gift giving may have adverse welfare implications especially for the poor and 3 escalating gift expenses crowd out expenditures on other consumption items

arbitrage across borders why itunes gift cards sell above face value on ebay i introduction firms that operate internationally often charge different prices for the same product in different countries these price differences may be due to cost differences exchange rate fluctuations and or price discrimination where firms set prices based on consumers willingness to pay for the product there is an extensive literature on international price differences but nearly all of this research has focused on physical goods where arbitrage the situation where someone buys the product from a low price country and resells it to someone in a high price country tends to be relatively costly because of transaction costs including search costs and transportation costs there have been no empirical papers in the economics literature thus far on the arbitrage of downloadable goods this paper looks at the case of itunes which sells downloadable music videos books ipad and iphone applications and other content worldwide and shows how the sale of itunes gift cards above face value on the auction website ebay is linked to the arbitrage of itunes products itunes which is operated by apple first started selling music downloads in 2003 and by 2008 it was the largest music retailer in the united states and the world 1 people typically purchase products from their own country specific itunes stores but not all content is available in all countries due in part to licensing restrictions and consumer preferences e g itunes does not sell music movies and tv shows in many countries prices also vary across countries as detailed in section iii of this paper one can easily switch to any other country s itunes store with just a few mouse clicks in particular the u s store would seem to be a natural focal point and it tends to have lower prices and a wider selection however in order to actually purchase something from the u s store one needs to have either a u s credit card or a u s itunes gift card available in denominations ranging from 10 to 100 in the primary market through apple and its authorized sellers such as wal mart and best buy as such it can be surmised that some individuals outside the united states may be willing to purchase itunes gift cards on ebay in order to gain access to the u s store it should be noted that itunes terms and conditions specify that the u s store s products are available only to buyers in the united states we can see the evidence for this through the sale of itunes gift cards on ebay nearly 200 itunes gift cards are sold daily on ebay about 10 of all gift cards and more than half of these itunes gift cards sell above face value a phenomenon that is unusual among gift cards after discussing some background information and related literature this paper examines more than 1 300 ebay transactions in february 2011 and finds that itunes gift cards targeted to international buyers which are often sent electronically are more likely to have higher prices controlling for seller reputation shipping charges and other variables this indicates that non u s buyers are willing to pay a premium for the gift cards because they are unable to obtain them otherwise information about the buyers countries allows us to see whether it is the u s store s greater product availability or its lower prices that buyers are interested in this paper addresses an important issue because of the rising popularity of the sales of downloadable content worldwide this market includes music videos books video games and applications the internet has also made it easier for buyers and sellers in different countries to find one another and in the case of digital products exchange goods if arbitrage is widespread firms may decide to either minimize price differences between countries stop selling in low price countries altogether or use the legal system or other methods to prevent arbitrage in terms of the big picture this issue has implications for social welfare copyright enforcement and international trade policies and governments in some countries may also be concerned if their citizens have access to goods that are banned

energy consumption and economic growth new evidence from meta analysis abstract the causal relationships between energy consumption and economic growth have given rise to much discussion but remain controversial alternative data sets based on different time spans countries energy policies and econometric approaches result in diverse outcomes a meta analysis using a multinomial logit model with 174 samples governing the relationships between gdp and energy consumption is applied here to investigate the major factors that affect these controversial outcomes the empirical results have demonstrated how the time spans subject selections including gdp and energy consumption econometric models and tools for greenhouse gases emission reduction characteristics significantly affect these controversial outcomes

the magic of the personal touch field experimental evidence on money appreciation as gifts this paper makes use of two field experiments to explore individual effort responses to gifts we extend the literature by looking at nonfinancial gifts and gifts that combine financial and nonfinancial elements with or without adding a personal touch we find that non pecuniary gifts that signal worker appreciation induce reciprocity most importantly we find that there are interaction effects between money and appreciation while money and appreciation are individually effective they only work well together when they are combined with a personal touch this points to the importance of interpersonal elements in gift giving and has important implications for how to effectively elicit worker effort

laboratory testbeds and non market valuation the case of bidding behavior in a second price auction with an outside option researchers now use the lab to examine the behavioral underpinnings of valuation before the field application which some argue has less experimental control but lab valuation work raises its own set of concerns when it uses private goods to explore non market valuation behavior because private goods have substitutes often unaccounted for in the lab therefore the lab as a tool to testbed field valuation work may be limited herein we design an induced valuation experiment to explore bidding behavior in a second price auction with an outside option that is a perfect substitute for the auction commodity theory predicts that rational bidders will consider the prices of outside options when formulating bidding strategies and will reduce their bids whenever their resale value exceeds the price of the outside option our results suggest that bidders account for outside options when formulating bids with behavior following comparative static predictions in addition we provide evidence concerning hypothetical versus actual behavior with induced values the data suggesting a hypothetical bias in the level of bids but not in bid shaving

an experiment on cash and in kind transfers with application to food assistance programs the impact of providing food assistance in kind via food stamps or restricted debit cards vs cash has long been a subject of debate prior efforts to causally identify the effects of the two types of transfers have been hindered by concerns over non random selection into assistance programs misreporting of program benefits and identification of inframarginal households who theoretically should treat cash and in kind transfers identically this paper reports the results of an economic experiment designed to cleanly test some conceptual issues associated with in kind vs cash giving in a lunchroom meal setting given current debates about the healthiness of food assistance recipients diets we also consider the impacts of placing restrictions on in kind transfers that either prohibit soda purchases with the transfer or require the transfer be spent on fruits and vegetables overall we find that as theory predicts in kind transfers have the same effect on food expenditures as an unrestricted cash transfer for inframarginal consumers and for extramarginal consumers food expenditures are higher for in kind than cash transfers participants also respond to the fruit and vegetable restriction as theory would predict however in contrast to the theoretical prediction the soda restriction reduces soda expenditures for more than half the inframarginal consumers

two stage perishable inventory models in this paper we consider perishable inventory systems with two types of demand demand may be for either fresh items or for somewhat older items we model the system with two inventory stages the first stage holds fresh items and the second stage holds the older items we approximate the performance of the two stage inventory system and compare two managerial policies

what goes up recent trends in china s energy consumption since 1996 china s energy output has dropped by 17 while primary energy use has fallen by 4 driven almost entirely by shrinking output from coal mines and declining direct use since china is the world s second largest emitter of greenhouse gases it is important to understand the sources of this apparent transformation and whether it portends a permanent change in patterns of energy use this remarkable reversal of the long term expansion of energy use has occurred even as the economy has continued to grow albeit more slowly than in the early 1990s generation of electric power has risen implying a steep fall in end uses particularly in industry available information points to a variety of forces contributing to this phenomenon including rapid improvements in coal quality structural changes in industry shutdowns of factories in both the state owned and non state segments of the economy improvements in end use efficiency and greater use of gas and electricity in households a combination of slowing economic growth industrial restructuring broader economic system reforms and environmental and energy efficiency policies has apparently led to at least a temporary decline in and perhaps a long term reduction in the growth of energy use and therefore greenhouse gas emissions

information transmission and the bullwhip effect an empirical investigation the bullwhip effect is the amplification of demand variability along a supply chain a company bullwhips if it purchases from suppliers more variably than it sells to customers such bullwhips amplifications of demand variability can lead to mismatches between demand and production and hence to lower supply chain efficiency we investigate the bullwhip effect in a sample of 4 689 public u s companies over 1974 2008 overall about two thirds of firms bullwhip the sample s mean and median bullwhips both significantly positive respectively measure 15 8 and 6 7 of total demand variability put another way the mean quarterly standard deviation of upstream orders exceeds that of demand by 20 million we decompose the bullwhip by information transmission lead time estimating the bullwhip s information lead time components with a two stage estimator we find that demand signals firms observe with more than three quarters notice drive 30 of the bullwhip and those firms observe with less than one quarter s notice drive 51 from 1974 1994 to 1995 2008 our sample s mean bullwhip dropped by a third this paper was accepted by christian terwiesch operations management

modeling gift choice the effect of uncertainty on price sensitivity abstractgift giving generates high revenues for retailers it is also marked with significant welfare or deadweight loss in that givers tend to pay more than the receivers valuation previous research has attributed this discrepancy to givers inaccurate predictions of the receivers preferences this research demonstrates that reduced price sensitivity is another important source of the deadweight loss givers use gift prices to signal the importance of their relationship with the receiver in order to demonstrate this mechanism the authors develop a new bayesian gift choice model that captures both preference predictions as well as the signaling value of price the model is estimated on two choice based conjoint studies for gift giving that allow for the manipulation of the giver s uncertainty about the receiver s preferences both studies show the strong signaling value of price especially when givers are uncertain about receivers preferences decomposition of the deadweight loss shows that the s

beyond gdp measuring and achieving global genuine progress article i nfo while global gross domestic product gdp has increased more than three fold since 1950 economic wel fare as estimated by the genuine progress indicator gpi has actually decreased since 1978 we synthesized estimates of gpi over the 1950 2003 time period for 17 countries for which gpi has been estimated these 17 countries contain 53 of the global population and 59 of the global gdp we compared gpi with gross domestic product gdp human development index hdi ecological footprint biocapacity gini coefficient and life satisfaction scores results show a significant variation among these countries but some major trends we also estimated a global gpi capita over the 1950 2003 period global gpi capita peaked in 1978 about the same time that global ecological footprint exceeded global biocapacity life satisfaction in almost all countries has also not improved significantly since 1975 globally gpi capita does not increase beyond a gdp capita of around 7000 capita if we distributed income more equitably around the planet the current world gdp 67 trillion yr could support 9 6 billion people at 7000 capita while gpi is not the perfect economic welfare indicator it is a far better approximation than gdp development policies need to shift to better account for real welfare and not merely gdp growth

how inefficient are multiple in kind transfers the inefficiencies from multiple in kind transfers are smaller than one would guess from studying such programs singly though medicaid can give rise to average discounts as large as 60 percent the benefits from the programs are quite large relative to recipients incomes effective marginal tax rates under in kind transfers are appreciably lower than they would be if the programs gave cash poverty rates among recipients are markedly lowered if one counts the value of in kind transfers as income this effect is insensitive to whether one accounts for the discounting of in kind transfers by recipients

the role of human social built and natural capital in explaining life satisfaction at the country level toward a national well being index nwi this paper investigates the contributions to life satisfaction of four basic types of capital human social built and natural life satisfaction data were available for respondents from fifty seven countries from the world values survey over the decade of the 1990s data on proxies for human social built and natural capital were available for 171 countries using data from the 1998 united nations human development report united nations development programme 1998 human development report 1998 oxford university press new york freedom house 1999 freedom house 1999 news of the century press freedom 1999 freedom house http freedomhouse org pfs99 pfs99 pdf september 30 2003 and sutton and costanza 2002 sutton p costanza r 2002 global estimates of market and non market values derived from nighttime satellite imagery land cover and ecosystem service valuation ecol econ 41 509 527 regression models show that both the un human development index hdi which includes proxies for both built and human capital and an index of the value of ecosystem services per km 2 as a proxy for natural capital are important factors in explaining life satisfaction at the country level and together can explain 72 of the variation in life satisfaction we did not find a proxy for social capital that was a significant predictor in the regression models this was due to the inadequacy of available proxy variables for social capital at the national scale and intercorrelation with other variables we discuss data limitations and a range of other problems with the existing limited data along with methods to overcome some of these limitations to improve future analyses we propose a national well being index nwi based on our findings and describe a path to improve it over time d 2005 elsevier b v all rights reserved

time is not money in an ultimatum bargaining experiment we study how subjects bargain over the returns to their investments of money and time the most notable finding is that a third of the subjects demand no compensation for their time investments whereas almost all subjects demand compensation for equally costly monetary investments

choosing for others abstractexperiments conducted in the us and france were used to study how individuals make trade offs between health and taste for themselves and others when someone receives a choice made for them that differs from their preference they experience a welfare loss at least in the short term we measure the empirical magnitude of this loss and suggest it play a role in assessing the desirability of paternalistic policies motivated by behavioural economics we show that the welfare loss changes with the provision of new information and the impact of this information differs for the two countries

directed giving evidence from an inter household transfer experiment abstract we investigate the determinants of giving in a lab in the field experiment with large stakes study participants in urban mozambique play dictator games where their counterpart is the closest person to them outside their household when given the option dictators do a large fraction of giving in kind in the form of goods rather than cash in addition they share more in total when they have the option of giving in kind compared to giving that can only be in cash qualitative post experiment responses suggest that this effect is driven by a desire to control how recipients use gifted resources standard economic determinants such as the rate of return to giving and the size of the endowment also affect giving but the effects of even large changes in these determinants are significantly smaller than the effect of the in kind option our results support theories of giving where the utility of givers depends on the composition not just the level of gift recipient expenditures and givers thus seek control over transferred resources

does increasing energy or electricity consumption improve quality of life in industrial nations among the world s nations per capita energy and electricity consumption is highly correlated with diverse indicators of quality of life this is often interpreted to mean that additional energy and electricity consumption causes improvements in life quality prior analyses of cross sectional data question this interpretation for industrial nations that already have high per capita energy consumption the present analysis with longitudinal data shows that among industrial nations increases in per capita energy and electricity consumption over the past three decades are not associated with corresponding improvements in quality of life

how larger demand variability may lead to lower costs in the newsvendor problem in this paper we consider the newsvendor problem intuition may lead to the hypothesis that in this stochastic inventory problem a higher demand variability results in larger variances and in higher costs in a recent paper song 1994a has proved that the intuition is correct for many demand distributions that are commonly used in practice such as for the normal distribution function however this paper shows that there exist demand distributions for which the intuition is misleading i e for which larger variances occur in combination with lower costs to characterize these demand distributions we use stochastic dominance relations

distribution of energy consumption and the 2000 w capita target this viewpoint discusses the intra and international distribution of energy consumption and their implications for intergenerational equity for global development to be sustainable the inequality of energy consumption must have an upper limit a graphic depiction of energy consumption distributions intra and international shows that today s inequalities are large and it is argued that we may have already reached or perhaps even surpassed the sustainability limit of energy consumption inequality

broad and narrow bracketing in gift certificate spending abstract we survey 1050 consumers who have just redeemed one or more open loop gift certificates to learn whether they view gift certificate income cash gifts and non gift income as substitutes we find that the majority 83 of recipients spend the certificates in the same way as cash the other respondents 17 bought an item they would not have bought otherwise but adjustments in their shopping pattern do not seem to result from constraints in redeeming the certificates 80 of all respondents in this group says they have used the certificate to buy an item they really love to have while inconsistent with standard microeconomic demand theory this behavior can be explained by narrow bracketing in spending gift certificates these consumers consider a limited choice set of nice personal items our data show that females are more likely to narrow bracket gift certificate income and that positive reciprocity towards the giver induces narrow bracketing in case the giver is a household member who suggests to buy a particular item using the certificate previous studies have found that both giving in kind gifts waldfogel 1993 as giving gift cards offenberg 2007 entail a welfare loss of 10 30 when compared to giving cash we find that the welfare effects of open loop gift certificates among users are limited the consumption of broad bracketing consumers is unaffected and narrow bracketing consumers seem to value the possibility to separate gift certificate income from other income sources

energy and quality of life energy is required to sustain life a human centered analysis of the worldwide energy situation is conducted in terms of quality of life related variables that are affected but not directly determined by energy consumption data since 1980 show a continuous global increase in both energy consumption and quality of life and lower population growth in countries with higher quality of life based on these trends we advance non linear energy consumption predictions and identify various plausible scenarios to optimally steer future energy demands in order to maximize quality of life the scenarios consider the coupling between energy consumption rate per capita quality of life population growth social inequality and governments energy for life efficiency the results show the energy cost of increasing quality of life in the developing world energy savings that can be realized by limiting overconsumption without impacting quality of life and the role of governments on increasing energy for life efficiency and reducing social inequality

the deadweight loss of christmas when economists comment on holiday gift giving it is usually to condone the healthy effect of spending on the macroeconomy however an important feature of gift giving is that consumption choices are made by someone other than the final consumer a potentially important microeconomic aspect of gift giving is that gifts may be mismatched with the recipients preferences in the standard microeconomic framework of consumer choice the best a gift giver can do with say 10 is to duplicate the choice that the recipient would have made while it is possible for a giver to choose a gift which the recipient ultimately values above its price for example if the recipient is not perfectly informed it is more likely that the gift will leave the recipient worse off than if she had made her own consumption choice with an equal amount of cash in short gift giving is a potential source of deadweight loss this paper gives estimates of the deadweight loss of holiday gift giving based on surveys given to yale undergraduates i find that holiday gift giving destroys between 10 percent and a third of the value of gifts while these recipients may be unrepresentative of the u s population their gifts are not necessarily unrepresentative holiday expenditures average 40 billion per year implying that a conservative estimate of the deadweight loss of christmas is a tenth as large as estimates of the deadweight loss of income taxation i also explore how deadweight loss and the tendency to give cash gifts vary with the relationship and age difference between giver and recipient i find that gifts from friends and significant others are most efficient while noncash gifts from members of the extended family are least efficient and destroy a third of their value i develop a simple expected utility model to explain the decision to give cash as opposed to in kind gifts the data are consistent with the model cash gifts are most common from the sorts of givers whose noncash gifts have the lowest expected value to recipients given their cost and high variability in recipient valuation

bullwhip effect measurement and its implications the bullwhip effect or demand information distortion has been a subject of both theoretical and empirical studies in the operations management literature in this paper we develop a simple set of formulas that describe the traditional bullwhip measure as a combined outcome of several important drivers such as finite capacity batch ordering and seasonality our modeling framework is descriptive in nature as it features certain plausible approximations that are commonly employed in practical inventory systems the results are nonetheless compelling and can be used to explain various conflicting observations in previous empirical studies building on the theoretical framework we discuss the managerial implications of the bullwhip measurement we show that the measurement can be completely noninformative about the underlying supply chain cost performance if it is not linked to the operational details such as decision intervals and leadtimes specifically we show that an aggregated measurement over relatively long time periods can mask the operational level bullwhip in addition we show that masking also exists under product or location aggregation in some illustrative cases

bridging the energy divide and securing higher collective well being in a climate constrained world abstract despite the impressive gains in available energy over the last 200 years the associated benefits remain unevenly distributed bridging this divide only adds to the already daunting challenge of securing climate stabilization in fact efforts towards the former are more likely to conflict with the latter to be able to address this dilemma the relationship between energy consumption and human well being beyond its economic dimension needs to be better understood this paper aims to contribute to the emerging knowledge base by examining this relationship using a proxy for human well being that also considers its environmental and social dimensions the ultimate goal of this paper is to investigate the potential incompatibility between efforts towards the achievement of higher collective well being and those associated with climate stabilization to this end it provides estimates of the additional energy needed and its associated carbon emissions under different climate scenarios and compares them with existing carbon budgets results indicate that even if new climate policies were adopted emissions associated with higher well being in all regions where improvements are needed could still reach up to one and a half times estimated 2 c budgets and even more so for lower temperature increase targets

willingness to pay and compensation demanded experimental evidence of an unexpected disparity in measures of value aside from possible income effects measures of the maximum amounts people will pay to avoid a loss and the minimum compensation necessary for them to accept it are generally assumed to be equivalent unexpectedly wide variations between these sums however have been noted in survey responses to hypothetical options this paper reports the results of a series of experiments that confronted people with actual money payments and cash compensations the results indicate that the compensation measure of value seems to exceed significantly the willingness to pay measure which would appear to call into some question various rules of entitlement damage assessments and interpretations of indifference curves

the inclusive wealth index a critical appraisal abstract among recent high profile propositions to revise national accounts and to provide new indicators of sustainability and well being the inclusive wealth framework and the related inclusive wealth index iwi undoubtedly stand out as one of the most promising endeavours built up at the confluence of welfare development and sustainability economics the indicator has been designed to bring information about the wealth of nations and their sustainability in a comprehensive way the inclusive wealth framework is nevertheless fraught with limitations due to questionable theoretical assumptions gaps in data availability unrealistic assumptions about the future and inability to account for distributional issues we propose a non exhaustive critical appraisal of the index and its underlying framework we conclude that these limitations undermine its capacity to fulfil the requirements of a satisfactory sustainability indicator we argue that most problems lie in the substantial discrepancy between the inclusive ambition of the indicator and the scarce means to implement it whereas the interconnectedness of the various assets that constitute wealth as well as their complex evolution through time are acknowledged by the proponents of inclusive wealth the way the iwi is computed is rather a mere addition of layers of actuarial like monetary values for a not inclusive yet range of capital assets caution is thus warranted while using such an approach and shorter range alternatives to pursue similar goals are proposed

intrinsic preference for information abstract suppose agents value information not only to make contingent plans but also intrinsically how are such attitudes toward information related to attitudes toward risk we generalize the kreps porteus recursive expected utility model dropping both recursivity and expected utility there is a geometric analogy between risk and information we characterize intrinsic information loving in general by a substitution property analogous to multivariate risk loving and for smooth preferences by the convexity of gateaux derivatives even with recursivity preference for information does not imply expected utility we provide an example we examine connections between information loving and risk aversion for early and late resolving risks journal of economic literatureclassification numbers d80 d81

cost minimizing welfare programs abstract we study opportunities for lowering the cost of welfare programs by exploiting heterogeneity in the unobservable tastes of welfare recipients relying on the inability of cash based programs to achieve self selection we provide circumstances in which it is optimal to provide payments in kind our model differs from other self selection models because we allow the recipients the opportunity to trade the subsequent to the receipt of their welfare packages the presence of unreported cash among the recipient population is considered

bid sensitivity and the structure of the vickrey auction a research study explored a version of economist w vickrey s second price sealed bid auction used for the valuation of nonmarket goods the sensitivity of revealed values generated by this variation were examined a standard second price auction with repeated market trials was compared to a random nth price auction and a combinatorial private collection auction with sequentially revealed values results showed the consistency of revealed values in a low probability risk scenario

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time

market reasoning as moral reasoning why economists should re engage with political philosophy abstract in my book what money can t buy the moral limits of markets 2012 i try to show that market values and market reasoning increasingly reach into spheres of life previously governed by nonmarket norms i argue that this tendency is troubling putting a price on every human activity erodes certain moral and civic goods worth caring about we therefore need a public debate about where markets serve the public good and where they don t belong in this article i would like to develop a related theme when it comes to deciding whether this or that good should be allocated by the market or by nonmarket principles economics is a poor guide deciding which social practices should be governed by market mechanisms requires a form of economic reasoning that is bound up with moral reasoning but mainstream economic thinking currently asserts its independence from the contested terrain of moral and political philosophy if economics is to help us decide where markets serve the public good and where they do
