competitive coupon targeting with the advent of panel data on household purchase behavior and the development of statistical procedures to utilize this data firms can now target coupons to selected households with considerable accuracy and cost effectiveness in this article we develop an analytical framework to examine the effect of such targeting on firm profits prices and coupon face values we also derive comparative statics on firms optimal mix of offensive and defensive couponing the number of coupons distributed redemption rates face values and incremental sales per redemption among our findings when rival firms can target their coupon promotions at brand switchers the outcome will be a prisoner s dilemma in which the net effect of targeting is simply the cost of distribution plus the discount given to redeemers

product and price competition in a duopoly this paper examines the role of consumer preferences costs and price competition in determining the competitive product strategy of a firm in the model studied here there are two identical firms competing on product quality and price they face consumers who prefer a higher quality product to a lower quality product but differ in how much they are willing to pay for quality the consumers can also choose a substitute if they don t like the product price offerings of the two firms for the firms a higher quality product costs more to produce than a lower quality product the paper shows that the equilibrium strategy for each firm should be to differentiate its product from its competitor with the firm choosing the higher quality choosing the higher margin as well this differentiation however is not efficient that is it is possible to choose two other products and offer them at prices that cover their marginal cost and still satisfy consumers needs better in the aggregate a monopolist by contrast would differentiate his product line efficiently this suggests that cannibalization has different effects on product strategy than competition the paper also shows that if one firm enters the market first then it can defend itself from later entrants and gain a first mover advantage by preempting the most desirable product position

energy consumption and gdp in developing countries a cointegrated panel analysis in this paper we re investigate the co movement and the causality relationship between energy consumption and gdp in 18 developing countries using data for the period 1975 to 2001 recently developed tests for the panel unit root heterogeneous panel cointegration and panel based error correction models are employed the empirical results provide clear support of a long run cointegration relationship after allowing for the heterogeneous country effect the long run relationship is estimated using a full modified ols the evidence shows that long run and short run causalities run from energy consumption to gdp but not vice versa this result indicates that energy conservation may harm economic growth in developing countries regardless of being transitory or permanent

a dynamic panel study of economic development and the electricity consumption growth nexus abstract this study examines the relationship between electricity consumption and economic growth for 88 countries categorized into four panels based on the world bank income classification high upper middle lower middle and low income within a multivariate panel framework over the period 1990 2006 the larsson et al 2001 panel cointegration test indicates there is a long run equilibrium relationship between real gdp coal consumption real gross fixed capital formation and the labor force for the high upper middle and lower middle income country panels the results from the panel vector error correction models reveal 1 bidirectional causality between electricity consumption and economic growth in both the short and long run for the high income and upper middle income country panels 2 unidirectional causality from electricity consumption to economic growth in the short run but bidirectional causality in the long run for the lower middle income country panel and 3 unidirectional causality from electricity consumption to economic growth for the low income country panel

social preferences under risk equality of opportunity versus equality of outcome this paper axiomatizes a utility function for social preferences under risk in the model a single parameter captures a preference for equality of opportunity i e equality of exante expected payoffs relative to equality of outcome i e equality of ex post payoffs in a deterministic environment the model reduces to the model of fehr and schmidt 1999 the model is consistent with recent experiments on probabilistic dictator games

energy consumption and economic growth new insights into the cointegration relationship abstract this paper examines the long run relationship between energy consumption and real gdp including energy prices for 25 oecd countries from 1981 to 2007 the distinction between common factors and idiosyncratic components using principal component analysis allows to distinguish between developments on an international and a national level as drivers of the long run relationship indeed cointegration between the common components of the underlying variables indicates that international developments dominate the long run relationship between energy consumption and real gdp furthermore the results suggest that energy consumption is price inelastic causality tests indicate the presence of a bi directional causal relationship between energy consumption and economic growth

if the worst comes to the worst dictator giving when recipient s endowments are risky abstract donors may often not be sure whether a recipient really needs their help does this uncertainty deter generosity we experimentally investigate a situation in which donors do not know the financial endowment of the recipient for certain but still have some information on the distribution the endowments are drawn from in the experiment we find that uncertainty does not deter generosity in fact if we filter out selfish dictators under most specifications of uncertainty dictators give more compared with the donation dictators make to a recipient they know to have the expected value of the endowment with certainty they are particularly concerned about the possibility of a recipient leaving the lab with no payoff from the game

energy consumption and economic growth evidence from 11 sub sahara african countries abstract the paper examines the causal relationship between energy consumption and economic growth for eleven countries in sub saharan africa using the autoregressive distributed lag ardl bounds test the study finds that energy consumption is cointegrated with economic growth in cameroon cote d ivoire gambia ghana senegal sudan and zimbabwe moreover this test suggests that energy consumption has a significant positive long run impact on economic growth in ghana kenya senegal and sudan granger causality test based on vector error correction model vecm shows bi directional relationship between energy consumption and economic growth for gambia ghana and senegal however granger causality test shows that economic growth granger causes energy consumption in sudan and zimbabwe the neutrality hypothesis is confirmed in respect of cameroon and cote d ivoire the same result of no causality was found for nigeria kenya and togo the result shows that each country should formulate appropriate energy conservation policies taking into cognizance of her peculiar condition

energy consumption and gdp causality relationship in g 7 countries and emerging markets abstract the causality relationship between energy consumption and income is a well studied topic in energy economics this paper studies the time series properties of energy consumption and gdp and reexamines the causality relationship between the two series in the top 10 emerging markets excluding china due to lack of data and g 7 countries we discover bi directional causality in argentina causality running from gdp to energy consumption in italy and korea and from energy consumption to gdp in turkey france germany and japan hence energy conservation may harm economic growth in the last four countries

an investigation of co integration and causality between energy consumption and economic activity in taiwan applying hsiao a version of the granger causality method this paper examines the causality between energy and gnp and energy and employment by applying recently developed techniques of co integration and hsiao s version of the granger causality to taiwanese data for the 1955 1993 period the phillips perron tests reveal that the series with the exception of gnp are not stationary and therefore differencing is performed to secure stationarity the study finds causality running from gdp to energy consumption without feedback in taiwan it is also found that causality runs from gdp to energy but not vice versa

price competition in markets for dichotomous substitutes abstract the paper deals with price rivalry between two sellers of a differentiated good each firm occupies one of the two possible locations in the characteristics space considered this resembles real situations like the choice between dichotomous substitutes or examples coming from spatial economics the consumers population is partitioned in two groups according to preferences and the population density is constituted by two atoms transportation costs vary across consumers nevertheless the resulting firms demand functions share the continuity property at a non cooperative equilibrium the prices of the two goods differ and some consumers who rank highest the more popular brand find it convenient to purchase the less expensive alternative higher one firm concentration ratios are found to be consistent with lower equilibrium prices this last feature is verified comparing the non cooperative outcomes stemming from different original population densities

excusing selfishness in charitable giving the role of risk decisions involving charitable giving often occur under the shadow of risk a common finding is that potential donors give less when there is greater risk that their donation will have less impact while this behaviour could be fully rationalized by standard economic models this article shows that an additional mechanism is relevant the use of risk as an excuse not to give in a laboratory study participants evaluate risky payoffs for themselves and risky payoffs for a charity when their decisions do not involve tradeoffs between money for themselves and the charity they respond very similarly to self risk and charity risk by contrast when their decisions force tradeoffs between money for themselves and the charity participants act more averse to charity risk and less averse to self risk these altered responses to risk bias participants towards choosing payoffs for themselves more often consistent with excuse driven responses to risk additional results support the existence of excuse driven types

just luck an experimental study of risk taking and fairness choices involving risk significantly affect the distribution of income and wealth in society this paper reports the results of the first experiment to our knowledge to study fairness views about risk taking specifically whether such views are based chiefly on ex ante opportunities or on ex post outcomes we find that even though many participants focus exclusively on ex ante opportunities most favor some redistribution ex post many participants also make a distinction between ex post inequalities that reflect differences in luck and ex post inequalities that reflect differences in choices these findings apply to both stakeholders and impartial spectators

a co integration analysis of the price and income elasticities of energy demand in turkish agriculture abstract agriculture has an important role in every country s development particularly the contribution of agriculture to development and competitiveness is increasing with agricultural productivity growth productivity in turn is closely associated with direct and indirect use of energy as an input therefore the importance of energy in agriculture cannot be denied as one of the basic inputs to the economic growth process following the importance of energy in turkish agriculture this study aims to estimate the long and short run relationship of energy consumption agricultural gdp and energy prices via co integration and error correction ecm analysis annual data from 1970 to 2008 for diesel and electricity consumptions are utilized to estimate long run and short run elasticities according to ecm analysis for the diesel demand model the long run income and price elasticities were calculated as 1 47 and 0 38 respectively for the electricity demand model income and price elasticities were calculated at 0 19 and 0 72 respectively in the long run briefly in turkey support for energy use in agriculture should be continued in order to ensure sustainability in agriculture increase competitiveness in international markets and balance farmers income

the evolution of u s airline competition studies by academic economists were a significant force in the movement towards deregulation of the domestic airline industry in the early 1970s levine 1965 jordan 1970 keeler 1972 douglas and miller 1974 during the critical 1977 78 period in which deregulation was imposed first de facto by the civil aeronautics board cab and then de jure by congress the chairman and vice chairman of the cab were economists for the 14 years since deregulation economists have continued intensive study of the industry in part because of the unusual availability of reliable firm and transaction level data and in part because of the rare opportunity to observe an industry as it evolves from strict economic regulation to fairly unimpeded competition and strategic behavior the simplest prediction of economists about airline deregulation and one of the few on which nearly all economists agreed was that deregulation would improve consumer welfare in comparison to continued price and entry regulation fourteen years later nearly all economists still agree on this though the degree of enthusiasm for the deregulation outcome varies considerably there was substantial disagreement among economists about the market structure that would result because studies of scale economies in the airline industry had concluded that none existed beyond the scale of the smaller major airlines of the 1970s caves 1962 eads et al 1969 many economists argued that deregulation would result in more than the 11 major airlines that existed at the time of deregulation others predicted that only a few or possibly only one airline would survive at a large scale two noted university of chicago economists sam peltzman and lester telser made a bet in 1979 on whether

product line rivalry and firm asymmetry we extend the brander and eaton 1984 model of product line rivalry to study the effects of asymmetry between firms on the equilibrium outcome our analysis shows that market interlacing can emerge as the equilibrium outcome even in situations where market segmentation would have been the only possible outcome had the firms been symmetric we identify two strategic factors that lead to such an outcome

product line rivalry and market segmentation with an application to automobile optional engine pricing this paper addresses the questions whether and when the pricing practices on base products may differ from those of premium products sold with options or add ons various alternative models are considered a monopoly model a model of brand rivalry with full consumer information and a model of rivalry in which consumers are only well informed about base product prices only the brand rivalry model with limited consumer information predicts that premium products have larger percentage markups than base products provided that brand rivalry is sufficiently intense empirical evidence on base and premium product pricing in the automobile market is consistent with the limited information model and inconsistent with the other two models

news consumption and media bias bias in the market for news is well documented recent research in economics explains the phenomenon by assuming that consumers want to read watch news that is consistent with their tastes or prior beliefs rather than the truth the present paper builds on this idea but recognizes that i besides biased consumers there are also conscientious consumers whose sole interest is in discovering the truth and ii consistent with reality media bias is constrained by the truth these two factors were expected to limit media bias in a competitive setting our results reveal the opposite we find that media bias may increase when there are more conscientious consumers however this increased media bias does not necessarily hurt conscientious consumers who may be able to recover more information from multiple media outlets the more the outlets are biased we discuss the practical implications of these findings for media positioning media pricing media planning and the targeting of advertising

a note on the causal relationship between energy and gdp in taiwan abstract this paper re examines the causality between energy consumption and gdp by using updated taiwan data for the period 1954 1997 as a secondary contribution we investigate the causal relationship between gdp and the aggregate as well as several disaggregate categories of energy consumption including coal oil natural gas and electricity applying granger s technique we find bidirectional causality between total energy consumption and gdp we find further that different directions of cause exist between gdp and various kinds of energy consumption

product customization and price competition on the internet the internet provides an unprecedented capability for sellers to learn about their customers and offer custom products at special prices in addition customization is more feasible today because of advances in manufacturing technologies that have improved sellers manufacturing flexibility we first develop a model of product customization and flexible pricing to incorporate the salient roles of the internet and flexible manufacturing technologies in reducing the costs of designing and producing tailored consumer goods we show how a monopoly seller may earn the highest profits by producing both standard and custom products and can raise prices for both types of products as customization and information collection technologies improve simultaneous adoption of customization in a duopoly reduces the differentiation between their standard products but does not intensify price competition compared with a two facility monopolist the duopoly may underinvest in customization consumer surplus improves after sellers adopt customization but does not monotonically increase as customization technologies advance when firms face a fixed entry cost and adopt customization sequentially the first entrant always achieves an advantage and may be able to deter subsequent entry by choosing its customization scope strategically

does willful ignorance deflect punishment an experimental study abstract this paper studies whether people can avoid punishment by remaining willfully ignorant about possible negative consequences of their actions for others we employ a laboratory experiment using modified dictator games in which a dictator can remain willfully ignorant about the payoff consequences of his decision for a receiver a third party can punish the dictator after observing the dictator s decision and the resulting payoffs on the one hand willfully ignorant dictators are punished less if their actions lead to unfair outcomes than dictators who reveal the consequences before implementing the same outcome on the other hand willfully ignorant dictators are punished more than revealing dictators if their actions lead to fair outcomes we conclude that willful ignorance can circumvent blame when unfair outcomes result but that the act of remaining willfully ignorant is itself punished regardless of the outcome models of procedural fairness combining ex ante and ex post fairness qualitatively predict the observed punishment pattern

on the causal dynamics between economic growth renewable energy consumption co2 emissions and trade openness fresh evidence from brics countries abstract the current study investigates the causal relationship between economic growth and renewable energy consumption in the brics countries over the period 1971 2010 within a multivariate framework the ardl bounds testing approach to cointegration and vector error correction model vecm are used to examine the long run and causal relationships between economic growth renewable energy consumption trade openness and carbon dioxide emissions empirical evidence shows that based on the ardl estimates there exist long run equilibrium relationships among the competing variables regarding the vecm results bi directional granger causality exists between economic growth and renewable energy consumption suggesting the feedback hypothesis which can explain the role of renewable energy in stimulating economic growth in brics countries

disaggregated industrial energy consumption and gdp the case of shanghai 1952 1999 abstract this paper investigates the causal relationship between various kinds of industrial energy consumption and gdp in shanghai for the period 1952 1999 using a modified version of the granger 1969 causality test proposed by toda and yamamoto j econ 66 1995 225 the empirical evidence from disaggregated energy series seems to suggest that there was a uni directional granger causality running from coal coke electricity and total energy consumption to real gdp but no granger causality running in any direction between oil consumption and real gdp

energy consumption and gdp in tunisia cointegration and causality analysis abstract in this paper the johansen cointegration technique is used to examine the causal relationship between per capita energy consumption pcec and per capita gross domestic product pcgdp for tunisia during the 1971 2004 period in order to test for granger causality in the presence of cointegration among the variables a vector error correction model vecm is used instead of a vector autoregressive var model our estimation results indicate that the pcgdp and pcec for tunisia are related by one cointegrating vector and that there is a long run bi directional causal relationship between the two series and a short run unidirectional causality from energy to gross domestic product gdp the source of causation in the long run is found to be the error correction terms in both directions hence an important policy implication resulting from this analysis is that energy can be considered as a limiting factor to gdp growth in tunisia conclusions for tunisia may also be relevant for a number of countries that have to go through a similar development path of increasing pressure on already scarce energy resources

linear and nonlinear causality between sectoral electricity consumption and economic growth evidence from taiwan this study investigates the linear and nonlinear causality between the total electricity consumption tec and real gross domestic production rgdp unlike previous literature we solve the undetermined relation between rgdp and electricity consumption by classifying tec into industrial sector consumption isc and residential sector consumption rsc as well as investigating how tec isc and rsc influence taiwan s rgdp by using the granger s linear causality test it is shown that i there is a bidirectional causality among tec isc and rgdp but a neutrality between rsc and rgdp with regard to the linear causality and ii there is still a bidirectional causality between tec and rgdp but a unidirectional causality between rsc and rgdp with regard to the nonlinear causality on the basis of i and ii we suggest that the electricity policy formulators loosen the restriction on isc and limit rsc in order to achieve the goal of economic growth

energy consumption and economic growth the case of oil exporting countries this paper examines the causal relationship between the per capita energy consumption and the per capita gdp in a panel of 11 selected oil exporting countries by using panel unit root tests and panel cointegration analysis the results show a unidirectional strong causality from economic growth to energy consumption for the oil exporting countries the findings have practical policy implications for decision makers in the area of macroeconomic planning in most major oil exporting countries government policies keep domestic prices bellow free market level resulting in high levels of domestic energy consumption the results imply that the energy conservation through reforming energy price policies has no damaging repercussions on economic growth for this group of countries

energy use for economic growth a trivariate analysis from tunisian agriculture sector abstract following the importance of energy in the agrarian economies the investigation of the causal relationship between energy consumption in agriculture sector and economic growth has a fundamental role in implementing suitable policies this paper examines the causal relationship between energy consumption and agricultural value added controlling for trade openness in tunisia from 1980 to 2007 the relationship is investigated at aggregated as well as disaggregated components of energy consumption including oil and electricity using granger s technique it is shown that various results are obtained regarding the direction of causality between competing variables nevertheless the most common finding suggest that trade openness and both aggregated and disaggregated energy consumption granger causes agricultural value added therefore the energy led growth and trade led growth hypotheses are supported in the tunisian agriculture sector an important policy implication resulting from this study is that energy can be considered as a limiting factor to agriculture value added and therefore shocks to energy supply would have a negative impact onto agriculture performance furthermore trade liberalization seems to be a stimulus factor to the tunisian agriculture development

use renewables to be cleaner meta analysis of the renewable energy consumption economic growth nexus abstract the renewable energy consumption economic growth nexus is a growing area of research over the last few years emanating to mixed results the aim of the current study is to quantitatively synthesise the empirical literature on the subject using the meta analysis approach in particular a meta multinomial regression is employed to investigate the sources of variation in the direction of causality between renewable energy consumption and economic growth this causal relationship takes the form of four hypotheses namely the feedback conservation growth and neutrality hypotheses to the best of author s knowledge this study constitutes the first meta analysis undertaken on the renewable energy consumption economic growth nexus the empirical results reveal that the variation in the supported hypotheses is due to a number of characteristics including model specification data characteristics estimation techniques cointegration methods and causality tests and development level of the country on which a study was conducted

behavior based discrimination is it a winning play and if so when with advances in technology the collection of information from consumers at the time of purchase is common in many categories this information allows a firm to straightforwardly classify consumers as either new or past consumers this opens the door for firms to implement marketing that a discriminates between new and past consumers and b entails making offers to them that are significantly different our objective is to examine the competitive effects of marketing that tailors offers to consumers based on their past buying behavior in a two period model with two competing firms we assume that each firm is able to commit about whether or not to implement behavior based discrimination bbd i e to add benefits to its offer for past consumers in the second period when the firms are identical in their ability to add value to the second period offer bbd generally leads to lower profits for both firms past customers are so valuable in the second period that bbd leads to cutthroat competition in the first period as a result the payoffs associated with the implementation of bbd form a prisoner s dilemma interestingly when a firm has a significant advantage over its competitor one firm has the capability to add more benefits for its past customers than the other it can increase its profit versus the base case even when there is significant competition in the second period moreover the firm at a disadvantage sometimes finds that the best response to bbd by a strong competitor is to respond with a uniform price and avoid the practice completely

individual marketing with imperfect targetability our research investigates the competitive ramifications of individual marketing and information management in today s information intensive marketing environments the specific managerial issues we address are as follows first what kinds of incentive environments do competing firms face when they can only target individual customers imperfectly second does the improvement in an industry s targetability intensify price competition in the industry such that all competing firms become worse off third should a firm share its customer knowledge so as to improve its rival s targetability fourth how should an information vendor sell its information that can improve a firm s targetability finally do competing firms have the same incentives to invest in their own targetability to answer those questions we develop a simple model a la narasimhan 1988 in which each of the two competing firms have their own loyal customers and compete for common switchers we assume that each firm can classify its own loyal customers and switchers correctly only with a less than perfect probability this means that each firm s perceived customer segmentation differs from the actual customer segmentation based on their perceived reality these two competing firms engage in price competition as an extension we also allow the competing firms to make their investment decisions to acquire targetability we show that when individual marketing is feasible but imperfect improvements in targetability by either or both competing firms can lead to win win competition for both even if both players behave noncooperatively and the market does not expand win win competition results from the fact that as a firm becomes better at distinguishing its price insensitive loyal customers from the switchers it is motivated to charge a higher price to the former however due to imperfect targetability each firm mistakenly perceives some price sensitive switchers as price insensitive loyal customers and charges them all a higher price these misperceptions thus allow its competitors to acquire those mistargeted customers without lowering their prices and hence reduce the rival firm s incentive to cut prices this effect softens price competition in the market and qualitatively changes the incentive environment for competing firms engaged in individual marketing a prisoner s dilemma occurs only when targetability in a market reaches a sufficiently high level this win win perspective on individual marketing has many managerial implications first we show that superior knowledge of individual customers can be a competitive advantage however this does not mean that a firm should always protect its customer information from its competitors to the contrary we find that competing firms can all benefit from exchanging individual customer information with each other at the nascent stage of individual marketing when firms targetability is low indeed under certain circumstances a firm may even find it profitable to give away this information unilaterally however as individual marketing matures as firms targetability becomes sufficiently high further improvements in targetability will intensify price competition and lead to prisoner s dilemma therefore it is not only prudent politics but also a business imperative for an industry to seize the initiative on the issue of protecting customer privacy so as to ensure win win competition in the industry second we show that the firm with a larger number of loyal customers tends to invest more in targetability when the cost of acquiring targetability is high however the firm with a smaller loyal base can through information investment acquire a higher level of targetability than the firm with a larger loyal base as long as the cost of acquiring targetability is not too high as the cost further decreases competing firms will all have more incentives to increase their investments in targetability until they achieve the highest feasible level third an information vendor should make its information available nonexclusively exclusively when its information is associated with a low high level of targetability when the vendor does sell its information exclusively it should target a firm with a small loyal following if it can impart a high level of targetability to that firm finally our analysis shows that an information intensive environment does not doom small firms in fact individual marketing may provide a good opportunity for a small firm to leapfrog a large firm the key to leapfrogging is a high level of targetability or customer knowledge

why do all the flights leave at 8 am competition and departure time differentiation in airline markets abstract theoretical models of spatial product differentiation indicate that firms face two opposing incentives 1 minimize differentiation in order to steal customers from competitors and 2 maximize differentiation in order to reduce price competition using data on u s airline departure times from 1975 when fares were regulated and 1986 when fares were not regulated we empirically estimate the effect of competition on differentiation we find a negative relationship in both periods in 1986 however reductions in exogenous scheduling constraints increase differentiation implying that firms may be differentiating their products where possible to reduce price competition this effect is not apparent in the 1975 data

economic growth and energy consumption revisited evidence from linear and nonlinear granger causality the relationship between energy consumption and economic growth is considered as an imperative issue in energy economics previous studies have ignored the nonlinear behavior which could be caused by structural breaks in this study both linear and nonlinear granger causality tests are applied to examine the causal relationship between energy consumption and economic growth for a sample of asian newly industrialized countries as well as the u s this study finds evidence supporting a neutrality hypothesis for the united states thailand and south korea however empirical evidence on philippines and singapore reveals a unidirectional causality running from economic growth to energy consumption while energy consumption may have affected economic growth for taiwan hong kong malaysia and indonesia policy implications are also discussed

strategic product choice in differentiated markets widespread diversification of firms compels viewing them as a portfolio of activities rather than as entities competing independently in separate markets this paper posits that product specification or product choice is a distinct strategic variable in particular the optimal relationship between the new and existing products of an oligopolistic firm is examined in the absence of market size inequalities clustering or market invasion is shown to be the nash solution to the product choice game when firms play strategically

threshold cointegration and causality relationship between energy use and growth in seven african countries abstract the paper investigates the long run and the causality relationship between energy consumption and economic growth for seven sub saharan african countries during the period 1970 2007 using the gregory and hansen 1996a 1996b testing approach to threshold cointegration we find that energy consumption is cointegrated with economic growth in cameroon cote d ivoire ghana nigeria and south africa moreover this test suggests that economic growth has a significant positive long run impact on energy consumption in these countries before 1988 and this effect becomes negative after 1988 in ghana and south africa furthermore causality tests suggest bidirectional causality between energy consumption and real gdp in cote d ivoire and unidirectional causality running from real gdp to energy usage in the case of congo and ghana

exploring the relationship between agricultural electricity consumption and output new evidence from turkish regional data abstract this study investigates the relationship between agricultural electricity consumption and agricultural output for a panel of 12 regions of turkey for the period 1995 2013 in order to reveal the possible heterogeneity between regions empirical analyses are conducted for the whole panel data and two sub groups within the panel data namely coastal regions and non coastal regions the results from several panel unit root tests indicate that electricity consumption and output are stationary process at their levels for overall panel and the two specific groups by using the ols with regional fixed effects this study finds that coefficient estimate of electricity consumption on output is statistically significant and positive for overall regions coastal regions and non coastal regions in addition the results from the dumitrescu hurlin granger causality test show that there is unidirectional causality running from agricultural output to electricity consumption for non coastal regions and there is bidirectional causality between agricultural electricity consumption and output for overall panel and coastal regions findings and policy implications are further discussed

is generosity involuntary abstract we estimate the distribution of exit reservation prices in a dictator game the mean exit reservation price equals 82 of the dictator game endowment and only 36 of subjects have exit reservation prices consistent with selfish or social preferences

the perils of behavior based personalization behavior based personalization has gained popularity in recent years whereby businesses offer personalized products based on consumers purchase histories this paper highlights two perils of behavior based personalization in competitive markets first although purchase histories reveal consumer preferences competitive exploitation of such information damages differentiation similar to the classic finding that behavior based price discrimination intensifies price competition with endogenous product design there is yet a second peril it emerges when forward looking firms try to avoid the first peril by suppressing the information value of purchase histories ideally if a market leader serves all consumers on day 1 purchase histories contain no information about consumer preferences however knowing that their rivals are willing to accommodate a market leader firms are more likely to offer a mainstream design at day 1 which jeopardizes differentiation based on this understanding i investigate how the perils of behavior based personalization change under alternative market conditions such as firms better knowledge about their own customers consumer loyalty and inertia consumer self selection and the need for classic designs

sectoral energy consumption by source and economic growth in turkey this paper provides a detailed analysis of the energy consumption in turkey during the last 40 years it investigates the causal relationships between income and energy consumption in two ways first the relationship is studied at the aggregate level then we focus on the industrial sector previous findings suggest that in the case of turkey there is a unidirectional causality running from energy consumption to growth however our findings suggest that in the long run income and energy consumption appear to be neutral with respect to each other both at the aggregate and at the industrial level we also find a strong evidence of instantaneous causality which means that contemporaneous values of energy consumption and income are correlated furthermore a descriptive analysis is conducted in order to reveal the differences in the use of energy resources we conclude that energy conservation policies are necessary for environmental concerns and our empirical results imply that such policies would not impede economic growth in the long term

a model of add on pricing this paper examines competitive price discrimination with horizontal and vertical taste differences consumers with higher valuations for quality are assumed to have stronger brand preferences two models are considered a standard competitive price discrimination model in which consumers observe all prices and an add on pricing game in which add on prices are naturally unobserved and firms may advertise a base good at a low price in hopes of selling add ons at high unadvertised prices in the standard game price discrimination is self reinforcing the model sometimes has both equilibria in which the firms practice price discrimination and equilibria in which they do not the analysis of the add on pricing game focuses on the chicago school argument that profits earned on add ons will be competed away via lower prices for advertised goods a conclusion is that add on practices can raise equilibrium profits by creating an adverse selection problem that makes price cutting unappealing although profitable when jointly adopted using add on pricing is not individually rational in a simple extension with endogenous advertising practices and costless advertising several models that could account for add on pricing are discussed

fairness risk preferences and independence impossibility theorems the most widely used economic models of social preferences are specified only for certain outcomes there are two obvious methods of extending them to lotteries if we do so by expected utility theory so that the independence axiom is satisfied our results imply that the resulting preferences do not exhibit ex ante fairness if we do so by replacing certain outcomes with their expected utilities for each individual so that individual risk preferences are preserved then ex ante fairness may be preserved but neither the independence axiom nor ex post fairness is satisfied both ex ante and ex post fairness can be satisfied but then the individual does not have well defined preferences over own lotteries

product line rivalry with brand differentiation competition with product rivalry is examined in a model where products are differentiated by both quality and brand name with no commitment firms produce a full product line when firms can commit to restrict their product offerings firms specialize if the degree of brand specific differentiation is small and they produce a full product line if brand specific differentiation is large relative to intrafirm differentiation firms may crowd a product space when all competitors would be better off with specialization brand proliferation is a credible entry deterring strategy if the degree of brand specific differentiation is not too large copyright 1993 by blackwell publishing ltd

deception the role of uncertain consequences abstract we study how decisions to lie extend to risky environments we provide experimental evidence from a sender receiver game where there is uncertainty over the amount by which a sender s lie reduces its receiver s payoff which is known only to potential liar even though all reduction amounts are equiprobable ex post beliefs elicited from senders suggest that unlike truth tellers most liars underestimate the extent of the actual reduction in the receiver s payoff and appear to exploit this self serving bias resulting in substantially more lying relative to a baseline treatment without the uncertainty subsequent treatments confirm the bias by either providing additional evidence or by removing possible confounds an intervention treatment nudging senders toward correcting the bias reduces lying

can price competition dominate market segmentation this note analyses duopoly competition in a two stage location price game while allowing each firm to establish a couple of outlets both the circle and the line model of spatial competition are considered our main result is clear cut in equilibrium neither firm will take up the opportunity of opening two stores this is a warning that market segmentation i e competition from multiple outlets might not be attractive at all because it entails more intense price competition

on the strategic choice of spatial price policy the strategic incentives with respect to the choice of price policy in spatial competition are analyzed in a duopoly model price discrimination emerges as the unique equilibriu m outcome in games with either simultaneous choice of policy and pric e or sequential choice where firms may commit first to uniform mill p ricing before the actual market stage nevertheless profits may be h igher with uniform pricing the authors models are applied to analyz e some common business practices that arise in geographical pricing like the basing point system and in the pricing of varieties or opti ons from a base product in a product differentiation context copyright 1988 by american economic association

dynamic targeted pricing with strategic consumers abstract we investigate in this paper whether dynamic targeted pricing based on consumer purchase history could benefit a practicing firm even when consumers are strategic in that they actively seek to avail themselves of a low price in the future such strategic behavior on the part of consumers has been shown in the literature to render such dynamic targeted pricing unprofitable even for a monopoly firm we show that dynamic targeted pricing can benefit competing firms when they actively pursue customer recognition based on consumer purchase history this is because in order to pursue customer recognition competing firms need to price high to screen out price sensitive consumers and hence price competition is moderated as a result all competing firms can become better off with targeted pricing than without even when consumers behave strategically interestingly because of this competition moderation effect the paradoxical outcome occurs where dynamic targeted pricing may not benefit a monopolist but it may benefit competing firms we also show that dynamic targeted pricing can expand the market such that social welfare unambiguously improves

disaggregate energy consumption and industrial production in south africa abstract this paper tries to assess the relationship between disaggregate energy consumption and industrial output in south africa by undertaking a cointegration analysis using annual data from 1980 to 2005 we also investigate the causal relationships between the various disaggregate forms of energy consumption and industrial production our results imply that industrial production and employment are long run forcing variables for electricity consumption applying the toda h y yamamoto t 1995 statistical inference in vector autoregressions with possibly integrated processes journal of econometrics 66 225 250 technique to granger causality we find bi directional causality between oil consumption and industrial production for the other forms of energy consumption there is evidence in support of the energy neutrality hypothesis there is also evidence of causality between employment and electricity consumption as well as coal consumption causing employment
