toward a broadened theory of preference formation and the diffusion of innovations cases from zinder province niger republic the standard model for the diffusion of innovations in consumer behavior does not adequately account for the incorporation of novel items of non local origin into the material culture inventory of hausa speaking peasants in niger a synthetic culturally relative model composed of elements drawn from the standard diffusion paradigm from world systems theory and from economic and symbolic anthropology provides a more satisfactory account of these processes analysis shows that novel goods provide a medium through which alternative paradigms of consumer behavior and reality contend among the hausa a premarket model a western market mediated model and an islamic ethnonationalist model compete for consumer affiliation

productivity and efficiency at large and community banks in the us a bayesian true random effects stochastic distance frontier analysis this paper compares the productivity and efficiency of large banks and community banks in the united states over the period 1997 2006 this comparison is performed by estimating a true random effects stochastic distance frontier model a model that is capable of disentangling unobserved heterogeneity from inefficiency within a bayesian framework we find that failure to consider unobserved heterogeneity results in a misleading ranking of banks and mismeasured technical efficiency productivity growth and returns to scale our results show that compared with community banks large banks have experienced much higher productivity growth and higher levels of returns to scale our estimates of total factor productivity growth show a clear downward trend for both large and community banks and our decomposition of the output distance function based divisia productivity index indicates that technical change is the driving force behind this trend

short and long run demand for energy in mexico a cointegration approach abstract the objective of this paper is to estimate the demands for the different types of energy consumption for the mexican economy over the period 1965 2001 these demands are modeled as a function of output and the own real price the johansen j econ dynamics control 12 1988 231 procedure and the likelihood ratio tests indicate the existence of long run and stable relationships between each type of energy demand and income with the exception of the industrial sector where the cointegrating vector also includes the relative prices the weak exogeneity tests indicate that energy consumption and income do not reject the null hypothesis of weak exogeneity when relative prices are weak exogenous the final econometric models show that relative prices in the short run are relevant in all cases with the exception of the residential sector these results indicate that in mexico the demand for energy is fundamentally driven by income and that the effect of the relative prices is basically concentrated on the short run with the exception of the industrial sector which also shows a long term price impact the strong dependence of energy consumption with respect to income and the price inelastic response indicates that it is necessary to introduce strong measures to decouple energy consumption from output in order to obtain sustainable economic growth in mexico

the demand for residential electricity in south africa abstract this paper examines the residential demand for electricity in south africa as a function of real gross domestic product per capita and the price of electricity during the period 1978 2005 we make use of the bounds testing approach to cointegration within an autoregressive distributed framework suggested by pesaran et al 2001 bounds testing approaches to the analysis of level relationships journal of applied econometrics 16 3 289 326 following the literature we use a linear double logarithmic form using income and price as independent variables in the empirical analysis in the long run we find that income is the main determinant of electricity demand while electricity price is insignificant

residential consumption of gas and electricity in the u s the role of prices and income abstract we study the residential demand for electricity and gas working with nationwide household level data that cover recent years namely 1997 2007 our dataset is a mixed panel multi year cross sections of dwellings households in the 50 largest metropolitan areas in the united states as of 2008 we estimate static and dynamic models of electricity and gas demand we find strong household response to energy prices both in the short and long term from the static models we get estimates of the own price elasticity of electricity demand in the 0 860 to 0 667 range while the own price elasticity of gas demand is 0 693 to 0 566 these results are robust to a variety of checks contrary to earlier literature metcalf and hassett 1999 reiss and white 2005 we find no evidence of significantly different elasticities across households with electric and gas heat the price elasticity of electricity demand declines with income but the magnitude of this effect is small these results are in sharp contrast to much of the literature on residential energy consumption in the united states and with the figures used in current government agency practice our results suggest that there might be greater potential for policies which affect energy price than may have been previously appreciated

residential energy use and conservation economics and demographics energy consumption in the residential sector offers an important opportunity for conserving resources however much of the current debate regarding energy efficiency in the housing market focuses on the physical and technical determinants of energy consumption neglecting the role of the economic behavior of resident households in this paper we analyze the extent to which the use of gas and electricity is determined by the technical specifications of the dwelling as compared to the demographic characteristics of the residents our analysis is based on a sample of more than 300 000 dutch homes and their occupants the results indicate that residential gas consumption is determined principally by structural dwelling characteristics such as the vintage building type and characteristics of the dwelling while electricity consumption varies more directly with household composition in particular income and family composition combining these results with projections on future economic and demographic trends we find that even absent price increases for residential energy the aging of the population and their increasing wealth will roughly offset improvements in the energy efficiency of the building stock resulting from policy interventions and natural revitalization

electricity demand for south korean residential sector abstract this study estimates the electricity demand function for the residential sector of south korea with the aim of examining the effects of improved energy efficiency structural factors and household lifestyles on electricity consumption in the study time series data for the period from 1973 to 2007 is used in a structural time series model to estimate the long term price and income elasticities and annual growth of underlying energy demand trend uedt at the end of the estimation period the result shows a long term income elasticity of 1 33 and a long term price elasticity of 0 27 with 0 93 as the percentage growth of uedt at the end of the estimation period this result suggests that in order to encourage energy efficiency in the residential sector the government should complement the market based pricing policies with non market policies such as minimum energy efficiency standards and public enlightenment

residential energy expenditures and the relevance of changes in household circumstances this paper analyses the impact that dwelling characteristics and characteristics and behaviours of household members have on per capita energy expenditures it also analyses whether changes in household socio economic circumstances translate in changes in energy expenditures socio economic characteristics have a moderate impact while dwelling characteristics and especially household size have much larger impacts the largest changes in energy expenditures are due to changes in household size the recent socio demographic trends will make it harder to design policies to effectively reduce the carbon footprint of a country while policies influencing cohabitation and family size may have positive indirect effects

household energy use applying behavioural economics to understand consumer decision making and behaviour household energy conservation has emerged as a major challenge and opportunity for researchers practitioners and policymakers consumers also seem to be gaining greater awareness of the value and need for sustainable energy practices particularly amid growing public concerns over greenhouse gas emissions and climate change yet even with adequate knowledge of how to save energy and a professed desire to do so many consumers still fail to take noticeable steps towards energy efficiency and conservation there is often a sizeable discrepancy between peoples self reported knowledge values attitudes and intentions and their observable behaviour examples include the well known knowledge action gap and value action gap but neither is household energy consumption driven primarily by financial incentives and the rational pursuit of material interests in fact people sometimes respond in unexpected and undesirable ways to rewards and sanctions intended to shift consumers cost benefit calculus in favour of sustainable behaviours why is this so why is household energy consumption and conservation difficult to predict from either core values or material interests by drawing on critical insights from behavioural economics and psychology we illuminate the key cognitive biases and motivational factors that may explain why energy related behaviour so often fails to align with either the personal values or material interests of consumers understanding these psychological phenomena can make household and community responses to public policy interventions less surprising and in parallel can help us design more cost effective and mass scalable behavioural solutions to encourage renewable and sustainable energy use among consumers

residential electricity demand dynamics in turkey abstract this article provides fresh empirical evidences for the income and price elasticies of the residential energy demand both in the short run and long run for turkey over the period 1968 2005 using the bounds testing procedure to cointegration the computed elasticities of income and price are consistent with the previous studies and as expected the long run elasticities are greater than the short run elasticities an augmented form of granger causality analysis is implemented among residential electricity income price and urbanization in the long run causality runs interactively through the error correction term from income price and urbanization to residential energy but the short run causality tests are inconclusive the parameter stability of the short run as well as long run coefficients in the residential energy demand function are tested the results of these tests display a stable pattern

efficiency technical change and returns to scale in large us banks panel data evidence from an output distance function satisfying theoretical regularity abstract this paper provides parametric estimates of technical change efficiency change economies of scale and total factor productivity growth for large banks those with assets in excess of 1 billion in the united states over the period from 2000 to 2005 this is done by estimating an output distance function subject to theoretical regularity within a bayesian framework we find that failure to incorporate theoretical regularity conditions results in mismeasured shadow revenue and or cost shares which in turn leads to perverse conclusions regarding productivity growth our results from the regularity constrained model show that total factor productivity of the large us banks grew at an average rate of 1 98 over the sample period however our estimates also show a clear downward trend in the growth rate of total factor productivity and our decomposition of the primal divisia total factor productivity growth index into its three components technical change efficiency change and economies of scale indicates that technical change is the driving force behind this decline

fair trade in france from individual innovators to contemporary networks fair trade aims at humanising the capitalist economy by serving the community instead of simply striving for financial profit the current fair trade sector is an excellent example of an innovation where networks based on ethical principles can help to effectively serve this market our analysis is based on 48 interviews amongst fair trade innovators in france and illustrates the advent of a new type of entrepreneur one that is grounded in the social and solidarity economy sse based on a service dominant logic these innovators aim to construct a new world centred on trade relationships by integrating the role of multiple player networks into the creation of value in the market

the fair trade movement parameters issues and future research although fair trade has been in existence for more than 40 years discussion in the business and business ethics literature of this unique trading and campaigning movement between southern producers and northern buyers and consumers has been limited this paper seeks to redress this deficit by providing a description of the characteristics of fair trade including definitional issues market size and segmentation and the key organizations it discusses fair trade from southern producer and northern trader and consumer perspectives and highlights the key issues that currently face the fair trade movement it then identifies an initial research agenda to be followed up in subsequent papers

returns to scale at large banks in the us a random coefficient stochastic frontier approach abstract this paper investigates the returns to scale of large banks in the us over the period 1997 2010 this investigation is performed by estimating a random coefficient stochastic distance frontier model in the spirit of tsionas 2002 and greene 2005 2008 the primary advantage of this model is that its coefficients can vary across banks thereby allowing for unobserved technology heterogeneity among large banks in the us we find that failure to consider unobserved technology heterogeneity results in a misleading ranking of banks and mismeasured returns to scale our results show that the majority of large banks in the us exhibit constant returns to scale in addition our results suggest that banks of the same size can have different levels of returns to scale and there is no clear pattern among large banks in the us concerning the relationship between asset size and returns to scale due to the presence of technology heterogeneity

economies of scale and economies of scope in multiproduct financial institutions a study of british columbia credit unions this paper investigates the production technology facing computerized credit unions in canada a full system of translog cost equations is estimated in order to test for economies of scale economies of scope and other production characteristics in a multiproduct context the regression results indicate that most of the credit unions in our sample experience significant increasing returns to scale as they expand their level of output there is also evidence of cost complementarity or economies of scope in their mortgage and other lending activities as a result legislation which limits the ability of credit unions to grow and diversify will likely raise the operating costs of this important group of financial institutions additional structural tests of the most general translog specification suggest that none of the restrictive production conditions commonly imposed by other researchers using cobb douglas and ces specifications provide a valid representation of credit union technology the results of many earlier studies are therefore open to question this paper presents a number of structural tests of the production technology facing large computerized credit unions in canada a full system of translog cost equations is estimated using detailed cross sectional data on british columbia credit unions the parameter estimates obtained from our multiproduct specification allow us to test for economies of scale economies of scope and factor substitution unlike many earlier studies the present paper introduces the various outputs as separate variables instead of crudely proxying them with a single output measure such as total assets the total number of loans or the number of depositors by explicitly recognizing the multiproduct nature of the intermediation process we are able to address more interesting production questions and remove some of the bias caused by misspecification and measurement error in simpler approaches the flexible translog specification allows us to estimate the sensitivity of costs to proportionate increases in all outputs economies of scale as well as the cost savings firms realize by producing several outputs jointly rather than specializing in the production of one economies of scope the test results reported in the latter part of the paper suggest that increasing returns to scale exist in almost all of the credit unions in our sample though

income and price elasticities of electricity demand aggregate and sector wise analyses abstract cointegration and vector error correction modeling approaches are widely used in electricity demand analysis the study rigorously examines the determinants of electricity demand at aggregate and sectoral levels in pakistan in the backdrop of severe electricity shortages our empirical findings give support to the existence of a stable long run relationship among the variables and indicate that electricity demand is elastic in the long run to both income and price at aggregate level at sectoral level long run income and price elasticity estimates follow this pattern except in agricultural sector where electricity demand is found elastic to output but inelastic to electricity price on the contrary the coefficients for income and price are rather small and mostly insignificant in the short run we employed temperature index price of diesel oil and capital stock at aggregate and sectoral levels as exogenous variables these variables account for most of the variations in electricity demand in the short run it shows that mechanization of the economy significantly affect the electricity demand at macro level moreover elastic electricity demand with respect to electricity price in most of the sectors implies that electricity price as a policy tool can be used for efficient use and conservation

analysing households responsiveness towards socio economic determinants of residential electricity consumption in singapore abstract the research of household electricity use is still relatively new for singapore where apart from some government surveys and sparingly available papers not much has been done to understand the underlying socio economic determinants that affect residents energy demand here we seek to quantify price and income elasticities as well as provide reasonable justification for price asymmetry in singapore using a panel approach across dwelling types and geographical areas we find that households do not react much to prices and that price elasticities may decrease as income rises there is also some evidence of price asymmetry with surprising results putting responsiveness towards price decreases larger than price increases this points towards similar behavioural patterns with the rebound effect for household energy efficiency if found present in future studies our findings suggest that there will only be positive responses towards dynamic pricing and higher churn rates if more transparent information is provided on related cost savings when households are exposed to retail choice in the electricity market after full retail competition is introduced in 2018 in addition a large role will have to come from cultivating the young to engage in sustainable practices to achieve energy efficiency targets

opportunities and challenges in energy demand reduction for canadian residential sector a review abstract developing energy independent and sustainable communities has gained a high level of global interest in recent times the federal sustainable development strategy for canada fsds has defined the addressing of climate change and the shrinking of the environmental footprint as priority themes in its sustainable development approach in the pursuit of planning net zero to net positive community energy systems reducing the energy demand of the residential buildings is the first priority particularly as the residential sector accounts for 17 of the secondary energy use in canada various technical behavioural and policy level interventions are available for reducing residential energy consumption in this review demand reduction interventions have been categorised as efficiency saving and conservation measures the benefits limitations and challenges present in adopting those strategies are discussed for various regions in canada even though there is an advanced level of knowledge available on energy demand reduction the scattered information needs to be brought together to develop a combined and inclusive approach for residential demand management collected knowledge will inform decision makers engaged in the design of residential buildings and planning of sustainable communities to identify the interventions which can be implemented in a given locality this review aims to address the above gaps through a comprehensive review on potential energy demand reduction methods especially for canada the implications of the findings to canadian residential energy sector as a whole are discussed in the final part of the review

short and long run elasticities in us residential electricity demand a co integration approach abstract co integration techniques show promise in the analysis of short and long run effects of economic variables on energy use we use these techniques to develop an error correction model of annual us residential electricity demand we construct equipment stock indices and estimate the model for 1949 1993 our analysis suggests a structural shift in consumption during the 1960s we discuss reasons for this shift report the short and long run elasticities provide forecasts for 1994 1995 and compare the model s forecasts with other published forecasts

ethical value added fair trade and the case of cafe femenino this article engages various critiques of fair trade from its participation in commodification to providing a cover for fair washing corporations and argues that fair trade has the potential to answer the challenges contained within them if and when it initiates an ongoing process of developing the ethical valued added content of the label this argument is made in a number of ways first by distinguishing between economic and human development impacts and ethics this article argues that these impacts are necessary but not sufficient conditions for ethical trade second it engages the question of the possibility of ethical practice in economics generally developing the idea that when economics is concerned with securing the material basis of a broad range of life capacities it becomes ethical third fair trade practice itself is examined from this standpoint and is conceived of as both comprising a promising ethical value added practice as well as posing a problem in its current formulation that the framework of ethical value added can help understand and resolve finally an examination of these theoretical ideas in practice is undertaken through a case study of cafe femenino a fair trade coffee produced in peru in conclusion it is argued that for fair trade to build upon its economic and human impacts and therefore remain a meaningful ethical and economic alternative to corporate capitalism and globalization it must distinguish itself clearly in ethics from those market relations it wishes explicitly or implicitly to challenge

measuring banks market power in the presence of economies of scale a scale corrected lerner index abstract a positive lerner index indicates a welfare loss for consumers due to deviations from marginal cost pricing such a welfare loss may not always be due to market power though in particular marginal cost pricing would result in negative profit for the firm in the presence of economies of scale in such a scenario a positive lerner index could simply reflect the firm s need to earn non negative profits rather than market power we propose a novel scale corrected price cost margin for firms that produce in the economies of scale range we show that this measure is more informative about market power than the lerner index itself as an empirical illustration we analyze market power in the u s banking sector using both the corrected and uncorrected lerner index the corrected lerner index reveals significant market power for u s commercial banks during the 2000 2014 period

collectivism corporate social responsibility and resource advantages in retailing is corporate social responsibility csr linked to performance related instrumentality or real moral concerns does csr create resource advantages reasons for and results of csr remain unclear we choose a leading retail company in a confucian collectivist and high power distance society and ask whether managers are naturally oriented toward societal actions we study managerial perceptions regarding the importance and the performance of csr in relation to other management factors drawing on hunt s 2000 a general theory of competition resources competences productivity economic growth sage thousand oaks ca resource advantage theory we find that the perceived importance of csr is only fair vis a vis other management factors but its high performance makes it a core resource for the company

residential electricity demand in taiwan this paper examines the residential demand for electricity in taiwan as a function of household disposable income population growth the price of electricity and the degree of urbanization short and long term effects are separated through the use of an error correction model in the long run the income elasticity is unit elastic the own price effect is negative and inelastic in an error correction framework the short run income and price effects are small and less than the long run effects cooling degree day effects have a positive impact on short run consumption we have used a proxy variable urbanization to capture economic development characteristics and changes in electricity using capital stocks not explained by income the variable provides significant explanatory power to the model both in the short and long run we interpret it as controlling for economic development factors not captured by the pure income effect and we think it holds promise for explaining residential electricity consumption in other developing countries

the institutionalization of fair trade more than just a degraded form of social action the context of economic globalization has contributed to the emergence of a new form of social action which has spread into the economic sphere in the form of the new social economic movements the emblematic figure of this new generation of social movements is fair trade which influences the economy towards political or social ends having emerged from multiple alternative trade practices fair trade has gradually become institutionalized since the professionalization of world shops the arrival of fair trade products in the food industry and the establishment of an official fair trade label with the strength that this institutionalization has generated fair trade can now be considered a real trade system that questions as much as it renews the traditional economic system in parallel this transformation has exacerbated the tensions within the movement which can be characterized as a clash between a radical militant pole and a softer more commercial one however it is not the actual institutionalization of fair trade which is being debated among fair trade actors on either side of the fence but rather the challenges inherent in finding an economic institutionalization acceptable to social economic movements therefore the institutionalization process of fair trade should not be seen as mere degradation of social action but rather as typical of the institutionalization process of new social economic movements if we need to worry about the highjacking and alteration of the fair trade movement by the dominant economic system the opposite is no less likely as new social economic movements contribute to an ethical restructuring of markets

estimating residential demand for electricity in the united states 1965 2006 abstract this paper examines the residential demand for electricity in the us economy as a function of the per capita income the price of electricity the price of oil for heating purposes the weather conditions and the stock of occupied housing over the period 1965 2006 this paper has two novelties first the occupied stock of houses as a proxy for the stock of electrical appliances and second the identification of a possible equilibrium relationship among the variables is ascertained through the recently advanced ardl approach to cointegration our empirical findings give support to a stable long run relationship implying also short run and long run elasticities whose size and sign are comparable to other similar studies

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

the residential demand for electricity in australia an application of the bounds testing approach to cointegration this paper reports estimates of the long and short run elasticities of residential demand for electricity in australia using the bounds testing procedure to cointegration within an autoregressive distributive lag framework in the long run we find that income and own price are the most important determinants of residential electricity demand while temperature is significant some of the time and gas prices are insignificant our estimates of long run income elasticity and price elasticity of demand are consistent with previous studies although they are towards the lower end of existing estimates as expected the short run elasticities are much smaller than the long run elasticities and the coefficients on the error correction coefficients are small consistent with the fact that in the short run energy appliances are fixed

the impact of singapore s residential electricity conservation efforts and the way forward insights from the bounds testing approach abstract this article provides fresh empirical evidence of residential electricity demand in singapore over the period of 1980 2014 using the bounds testing procedure to cointegration the residential electricity demand comprises of income price temperature rainy days old age dependency and the impact of energy efficiency policies our results are consistent with previous studies where income and price elasticities are inelastic hence from a policy perspective subsidies will not be effective in reducing electricity demand we also found that old age dependency is an important determinant that reduces electricity consumption at least in the short run suggesting that policies that target the younger population may bring more savings the model findings suggest that in general energy efficiency interventions introduced after 2007 which comprises of both informational strategies and efficiency standards were effective in reducing household electricity consumption however in order to realise greater electricity reduction potential policy efforts have to intensify into the future with the main objectives being to permanently change energy habits and consider the role of hassle costs when rolling out energy saving measures

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment
