structural change in urban chinese food preferences we undertake a range of tests for structural food preference change in urban china using provincial level panel data from 2002 to 2010 we introduce a time transition function into the generalized quadratic almost ideal demand system gqaids to represent consumer preferences we apply this system to evaluate the demand structure for seven food groups the use of the gqaids specification relaxes many empirical demand system restrictions associated with previous analyses of structural preference change our findings suggest that chinese food preferences are continuing to evolve

fuel demand elasticities for energy and environmental policies indian sample survey evidence india has been running large scale interventions in the energy sector over the last decades still there is a dearth of reliable and readily available price and income elasticities of demand to base these on especially for domestic use of traditional fuels this study uses the linear approximate almost ideal demand system la aids using micro data of more than 100 000 households sampled across india the la aids model is expanded by specifying the intercept as a linear function of household characteristics marshallian and hicksian price and expenditure elasticities of demand for four main fuels are estimated for both urban and rural areas by different income groups these can be used to evaluate recent and current energy policies the results can also be used for energy projections and carbon dioxide simulations given different growth rates for different segments of the indian population

estimating theoretically consistent demand systems using cointegration techniques with application to greek food data abstract the use of time series techniques cointegration and error correction models has been offered as a potentially promising way in estimating demand systems that resolve the perennial issue of violating the theoretical postulates of homogeneity and symmetry the empirical results of this paper based on linearized aids and greek food data indicate that sample size aggregation schemes and model specification seem to be important factors in the estimation of a theoretically consistent demand system they also show that homogeneity is sensitive to sample size while symmetry is sensitive to the aggregation scheme adopted

an assessment of the current structure of food demand in urban china we evaluate the current structure of food demand in urban china by using household expenditure survey data from five provinces two complementary analyses are undertaken first an aggregate analysis based on a fractional logit model is used to examine how households allocate food expenditures across the food at home fah and food away from home fafh categories this is followed by a disaggregated analysis of how households allocated their fah expenditures across 12 commodity categories a quadratic almost ideal demand system quaids is used we find evidence of significant food purchase substitution and complementarity

seasonality and the estimation of dynamic demand systems some exploratory results abstract this note presents empirical comparisons of alternative ways of introducing seasonal fluctuations in theoretically plausible dynamic demand systems derived from non separable utility functions

nonbudgetary constraints in consumer demand for gasoline this paper develops a conceptual framework for taking into account nonbudgetary constraints in economic analysis of consumer demand for gasoline the individual s need for gasoline is defined and the process of satisfying the need is recognized thus nonbudgetary factors are used to restrict the consumption space to a relevant subset in the commodity space the restriction of the consumption space enables nonbudgetary factors to be included in a theoretical model of utility maximization this formulation implies the dependency of income and price elasticities on nonbudgetary factors in studies of the demand for gasoline as in many other empirical studies researchers are frequently confronted with the considerable gap existing between empirical relationships and economic theory this gap underlies the comment by henderson and quandt 1980 that theorists would provide examples that were of little aid for empirical work and econometricians would estimate relations that had little connection with utili

agency relationships in family firms theory and evidence does owner management necessarily eliminate the agency costs of ownership drawing on agency literature and on the economic theory of the household we argue that private ownership and owner management expose privately held owner managed firms to agency threats ignored by jensen s and meckling s 1976 agency model private ownership and owner management not only reduce the effectiveness of external control mechanisms they also expose firms to a self control problem created by incentives that cause owners to take actions which harm themselves as well as those around them jensen 1994 p 43 thus shareholders have incentive to invest resources in curbing both managerialand owner opportunism we extend this thesis to the domain of the family firm after developing hypotheses which describe how family dynamics and specifically altruism exacerbate agency problems experienced by these privately held owner managed firms we use data obtained from a large scale survey of family businesses to field test our hypotheses and find evidence which suggests support for our proposed theory finally we discuss the implications of our theory for research on family and other types of privately held owner managed firms

aggregate consumer behaviour and the measurement of inequality this paper presents an approach to inequality measurement based on an econometric model of aggregate consumer behaviour the novel feature of this model is that systems of individual demand functions can be recovered uniquely from the system of aggregate demand functions we present methods for evaluating social welfare based on an explicit social welfare function this social welfare function incorporates measures of individual welfare based on indirect utility functions for all consumer units we develop indexes of inequality based on actual and potential levels of social welfare

demand for food fats and oils the role of demographic variables and government donations a systems model of u s food fats and oils demand is estimated using quarterly time series data for the period 1962 87 demographic scaling is used to incorporate demographic variables and per capita government butter donations in addition to price income and demographic demand elasticities dietary fat intake elasticities are calculated for each of the demographic characteristics included in the study all of the five own price elasticities are statistically significant as are fifteen of the twenty cross price elasticities fourteen of the fifteen demographic elasticities are statistically significant

the pervasive effects of family on entrepreneurship toward a family embeddedness perspective families and businesses have often been treated as naturally separate institutions whereas we argue that they are inextricably intertwined long term changes in family composition and in the roles and relations of family members have produced families in north america that are growing smaller and losing many of their previous role relationships such transformations in the institution of the family have implications for the emergence of new business opportunities opportunity recognition business start up decisions and the resource mobilization process we suggest that entrepreneurship scholars would benefit from a family embeddedness perspective on new venture creation d 2003 elsevier science inc all rights reserved

utility functions and global regularity of fractional demand sytems fractional demand systems are utility derived demands having quantities or budget shares proportional to ag bf where g and f are functions of income and a and b vary across goods and are functions of prices many known demand systems that have large regular regions are fractional this paper derives the indirect utility functions that generate all fractional demand systems shows that these systems can all have large regular regions and provides sufficient conditions for their global or nearly global regularity an extension to rank three fractional demands is provided copyright 1995 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

modelling demand systems with demographic effects based on the modifying function approach abstract we follow review of economic studies 52 1985 1 approach to modify the standard consumer demand theory so that socio demographic variables can be formally incorporated into the demand systems our modified theory not only includes all previous approaches to this problem as special cases but also allows the useful interpretations of household production and subsistence expenditure

a latent variable model of consumer taste determination and taste change for complex carbohydrates despite evidence that aggregate consumption of complex carbohydrates has risen over the last decade food consumption surveys suggest that fewer households are consuming less bread pasta rice potatoes and corn this paper estimates systems of complex carbohydrae demand using cross sectional data from 1977 78 and 1987 88 in order to explain this paradox changes in demand that are not explained by changes in prices or income are explained by variations in taste because tastes cannot be directly observed the paper uses a multiple indicator and multiple cause mimic model to construct a suitable proxy variable in the mimic approach the indicators are residuals from a household demand function that includes prices and incomes as explanatory variables while household and demograhic proxies are cause variables the objectives in applying the mimic model are to determine the effect of consumer tastes on complex carbohydrate demand and comparing cross sectional survey data from two different periods

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

contextual influences on the corporate entrepreneurship performance relationship a longitudinal analysis abstract over the past several years corporate entrepreneurship has been widely touted by executives and researchers alike as an effective means for revitalizing companies and improving their financial performance for the most part the call for greater entrepreneurial behavior on the part of established companies has been accepted on faith as an inherently desirable objective the implicit logic behind the pervasive belief in the value of corporate entrepreneurship seems to be that risk taking innovation and aggressive competitive action the key elements of entrepreneurial corporations will help in identifying and pursuing lucrative product market opportunities and in providing new bases for achieving superior competitive positions but what do we really know about the financial consequences of corporate entrepreneurship most of the evidence that corporate entrepreneurship pays off is anecdotal in nature or based on cross sectional studies that focus on the short term implications of entrepreneurial behaviors as such in a definitive sense we know very little about the financial consequences of corporate entrepreneurship in an attempt to improve our understanding of this issue this article describes a study of corporate entrepreneurship and its impact on company financial performance data were collected from three different samples over a seven year period to assess the longitudinal impact of corporate entrepreneurship on firm performance these samples consist of 24 medium sized manufacturing firms representing 14 industry segments 39 chemical companies and 45 fortune 500 industrial firms representing five industry segments data were gathered on each sample using both primary and secondary sources regression analysis was then used to analyze the data the results suggest that corporate entrepreneurship has a positive impact on financial measures of company performance this effect on performance which tends to be modest over the first few years increases over time suggesting that corporate entrepreneurship may indeed be a generally effective means for improving long term company financial performance moreover the results indicate that corporate entrepreneurship is a particularly effective practice among companies operating in hostile environments as opposed to benign environments the study has three principal implications for practicing managers first the study documents the general financial viability of engaging in corporate entrepreneurship this is not to suggest that corporate entrepreneurship is a panacea for improving financial performance however entrepreneurial behavior when considered on the whole i e across firms and industries is associated with superior financial performance second the study suggests a need to use a long term time horizon in order to adequately judge the financial consequences of corporate entrepreneurship the use of a shorter evaluation period may not allow sufficient time for entrepreneurial actions to have their full market and corresponding financial impact finally the study identifies the context specific character of effective entrepreneurial practice specifically corporate entrepreneurship appears to be a particularly effective strategic practice among firms operating in hostile business settings

recovering individual preferences for non market goods a collective travel cost model traditional recreation demand models do not make a distinction between a household and an individual as the reference decision making unit thus assuming that a family maximizes a single utility function even if the family consists of different individuals such models ignore the possibility of family members divergent preferences for non market goods this study proposes a novel approach the collective travel cost model ctcm to eliciting individual preferences for a non market good such as a recreation site by using revealed preference data this approach accounts for the intra household resource allocation and the role of each household member s preferences we show that the collective travel cost model can be applied to estimating a recreation demand model that yields individual welfare estimates appropriate for policy analysis of non market goods such as the willingness to pay to access a recreation site we find that how resources are distributed within the household reflects significant differences in welfare measures

estimating consumption economies of scale adult equivalence scales and household bargaining power how much income would a woman living alone require to attain the same standard of living that she would have if she were married what percentage of a married couple s expenditures are controlled by the husband how much money does a couple save on consumption goods by living together versus living apart we propose and estimate a collective model of household behaviour that permits identification and estimation of concepts such as these we model households in terms of the utility functions of its members a bargaining or social welfare function and a consumption technology function we demonstrate generic non parametric identification of the model and hence of a version of adult equivalence scales that we call indifference scales as well as consumption economies of scale the household s resource sharing rule or members bargaining power and other related concepts copyright 2013 oxford university press

linear household technologies this paper discusses estimates and formally compares the best known procedures for incorporating demographic variables into complete demand systems in particular a class of general procedures belonging to gorman s family of general linear household technologies is introduced estimation and comparison of different procedures make use of italian household budget data for the years 1973 1992 incorporating a single demographic variable family size into a generalized quadratic almost ideal demand system in our empirical example however even the most general household technologies are unable to fully capture the behavioural heterogeneity shown by the data copyright 2000 john wiley sons ltd

equivalence scales in a rank 3 demand system abstract in the context of a rank 3 demand system equivalence scales measuring the cost of demographic characteristics independently of the base utility level can be identified from cross section data without demographic separability restrictions although this can also be achieved with a rank 2 demand system that contains a nonlinear log expenditure term in its budget shares tests performed in a nested framework suggest that the rank 3 demand system approach is empirically superior the informative structure of the rank 3 demand system is used to estimate a detailed pattern of demographic costs including the cost of single parenthood and economies of scale within the family

a two stage rural household demand analysis microdata evidence from jiangsu province china in this paper we evaluate economic and demographic effects on china s rural household demand for nine food commodities vegetables pork beef and lamb poultry eggs fish sugar fruit and grain and five nonfood commodity groups clothing fuel stimulants housing and durables a two stage budgeting allocation procedure is used to obtain an empirically tractable amalgamative demand system for food commodities which combine an upper level aids model and a lower level gles as a modeling framework the results indicate that the slow growth of food consumption in china during the latter half of the 1980s is a result of income stagnation rather than consumption saturation growth in the demand for better food and shelter by chinese rural households will continue to be a major concern

contemporaneous and intertemporal child costs equivalent expenditure vs equivalent income scales abstract parents may provide for their children by drawing on savings or borrowing as well as by reducing current consumption this means that child costs may be partly paid from reducing consumption in periods when the children themselves are not in the family static comparisons of consumption costs between households with and without children are therefore affected by the extent to which parents are willing and able to meet child costs through intertemporal transfers this paper analyses the implications of this argument for the estimation of adult equivalent scales and provides empirical illustrations using individual household data

management control systems in family firms a review of the literature and directions for the future family firms play a significant role in the global economy although family firm literature has devoted much time and effort to investigating topics concerning corporate governance leadership ownership and succession accounting issues have received relatively scant attention in this paper we assemble and critically review extant literature on the choice of management controls this is an essential topic for firms as management control systems mcs are used to make sure subordinates behave in function of the goals of the firm family firms however have distinct features such as differences in governance structures and goals which can have a significant impact on whether and how mcs are used we conclude this review paper by providing avenues for future research that can advance our understanding of both the determinants and the outcomes of the choice of mcs

habit formation and demand for sugar sweetened beverages using scanner data we estimated demand for nine nonalcoholic beverages under habit formation we found strong evidence for habit formation although demand for sugar sweetened beverages by low income households is less elastic to own price changes compared with high income households there is evidence that high income households consider beverages to be more substitutable than low income households do a half cent per ounce tax on store purchased sugar sweetened beverages will result in a moderate reduction in consumption of sugar sweetened beverages for both income strata because of habit formation long run national tax revenue from a sugar sweetened beverage tax is about 15 to 20 lower than short run revenue

entrepreneurial orientation and small business performance a configurational approach the strategy and entrepreneurship literatures suggest that an entrepreneurial orientation eo improves firm performance but the empirical results are mixed in this article we investigate the eo of small businesses and find that a main effects only analysis provides an incomplete picture of performance access to capital and the dynamism of the environment are important to small businesses and we find that when combined with eo a three way interaction model the configurational approach explains variance in performance over and above a contingency model two way interactions and a main effects only model

a nonparametric revealed preference approach to measuring the value of environmental quality we develop an approach to valuing non market goods using nonparametric revealed preference analysis we show how nonparametric methods can also be used to bound the welfare effects of changes in the provision of a non market good our main context is one in which the non market good affects the marginal utility of consuming a related market good this can also be framed as a shift in the taste for or quality of the market good a systematic approach for incorporating quality taste variation into a revealed preference framework for heterogeneous consumers is developed this enables the recovery of the minimal variation in quality required to rationalise observed choices of related market goods the variation in quality appears as a adjustment to the price for related market goods which then allows a revealed preference approach to bounding compensation measures of welfare effects to be applied

demographics and demand evaluation of alternative functional forms abstract we evaluate the role of functional form of demographics in demand analysis by proposing the gql unstructured demographically transformed model which nests the barten gorman demographically modified model and popular rank 3 and rank 2 demand systems we use uk individual data and find that the equivalence of the unstructured and barten gorman forms and identification of meaningful equivalence scales depend on the degree of flexibility of the demand system in demographic price and income effects

demographic variables in demand analysis in this paper the authors discuss five procedures for incorporating demographic variables into theoretically plausible demand systems translating scaling and the gorman reverse gorman and implicit prais houthakker procedures these five procedures are used to incorporate a single demographic variable the number of children in a household into the generalized ces demand system using household budget data for the united kingdom for the period 1966 1972 excerpt

equivalence scales and the costs of disability abstract the impact of disability on household welfare is estimated by equivalence scales using data from the 1986 1987 fes disability survey three methods of identifying scales from cross section data are considered these imply a series of restrictions that are tested on quadratic logarithmic engel curves the results indicate that there are substantial consumption costs associated with physical disability

does family employment enhance mses performance integrating socioemotional wealth and family embeddedness perspectives abstract this paper analyzes the effect of family employment on performance in micro and small enterprises mses by combining two research perspectives that until now have been conducted separately the family embeddedness perspective of entrepreneurship aldrich and cliff 2003 and the socioemotional wealth sew approach to family business gomez mejia et al 2007 our integrated perspective allows us to highlight how the nature of the employment relationships in mses enhances the benefits derived from the socioemotional endowment associated with family labor and reduces the opportunity costs of employing relatives moreover we assert that this relationship is moderated by specific family characteristics that determine the firm s ability to preserve the sew while at the same time pursuing financial goals our results provide partial support to the enhancing role of family labour on mses performance employing family members increases sales but decreases profitability as measured by roa this effect also results in improved performance for women led firms and for firms that have received family funding but impairs mses performance when the business is the main source of the owner s household income

an econometric analysis of urban households animal products consumption in turkey people in developing countries are increasing their consumption from the very low levels of the past and they have a long way to go before coming near developed country averages in this study households animal products consumption patterns are analysed by using linear approximation of almost ideal demand system la aids and survey data collected from households in urban areas in turkey according to the results of the study annual per capita consumption of animal products were 48 18 kg for milk 26 89 kg for yogurt 18 55 kg for cheese 6 45 kg for meat 22 11 kg for poultry and 10 05 kg for fish price elasticities were found to be lower than 1 for milk yogurt cheese poultry and fish and higher than 1 for meat moreover the impacts of socio demographic factors on the demand for animal products were found to be very low determination of production targets and formulation of polices are possible by obtaining the proper information related to the livestock products

determinants of food consumption in rural sierra leone abstract this paper reports the application of a quadratic expenditure system with demographic variables to the household consumption leisure choice component of a household firm model a system of seven commodities is estimated including five foods non food and leisure appropriate for such a level of disaggregation a demand system is used the quadratic expenditure system which allows for a flexible relationship between full income and commodity expenditures without sacrificing parsimony in parameters demographic data on households are explicitly incorporated into the model allowing for a richer specification than can be achieved by using per capita variables the data are from a cross section survey of households in rural sierra leone price variation exists by region permitting estimation of a complete demand system engel curves are found to be significantly non linear with marginal expenditure on rice the major staple declining with higher income most foods are found to be reasonably price responsive with sizeable own price substitution effects declining with higher income aggregate labor supply is found to be price inelastic

a structural model of the analysis of retail market power the case of fluid milk we derive a structural model of firm behavior that is composed of the generalized quadratic almost ideal demand system to represent both consumers milk preferences and firm profit maximization conditions that allow for a range of competitive scenarios the importance of this specification is found in its fuller representation of consumer preferences as opposed to the linear approximate almost ideal demand system used in previous analyses we apply this structural framework to investigate retailer conduct in the sale of beverage milk in a u s market using product level data our lerner index estimates show that retailers are not perfectly competitive however this deviation is small copyright 2012 oxford university press

household equivalence scales and welfare comparisons abstract the ratio of cost functions of different households facing the same prices and attaining the same utility level is a true cost of demographic characteristics index this index is independent of a base level of income or utility ib if and only if it equals a ratio of household equivalence scales that are themselves ib applied cost index and equivalence scales specifications are usually ib this paper describes the general restrictions on cost functions and social welfare functions required for ib scales and for their use in welfare analysis

towards a neoaristotelean theory of politics a positive account of fairness the argument suggests that it is very hard to separate how in fact economists use theory and how the subjects of economics use theory further we can explain why after a dazzling wave of the hands so much popular discussion of economic policies switches from real valued considerations to infinitely valued considerations and why it seems that only economists object it has been the fate of economists across the centuries to insist that costs do matter a proposition presupposing a world purged of infinities for if there is an infinite distance between commodities a noneconomist would have written down one word for the higher things and another for the lower then cost truly does not matter we have given a positive account of fairness and generated some implications about the content of public opinion which will be relatively straightforward to test

stratification and public utility services in colombia subsidies to households or distortion of housing prices domiciliary public utility services in colombia have a cross subsidy system which charges subsidized rates to the households who live in houses located in strata associated to low wealth levels and taxed rates to the better off we assesses the hypothesis that the flow of subsidies that potentially come from a particular house are discounted by housing market agents so that most of them are transferred to the prices of the houses that generate the subsidies by estimating a hedonic prices model applying a regression discontinuity approach we find that the increment in house value estimated because of subsidies is similar in magnitude to the present value of the flow of subsidies likely effects are found on the rent amount we conclude that subsidies to the poor population through public spending in domiciliary public utility services in colombia is being achieved if anything in a very limited way most of the financial effort on this subject ends up distorting housing relative prices according to socioeconomic strata with an annual cost of up to 0 7 of gdp in supposed gross subsidies to domiciliary public utility services

measuring the environmental consequences of trade policy a nonmarket cge analysis the newly approved gatt trade agreement is likely to focus greater attention on the conflicts between the proliferation of diverse national policies toward environmental quality and the need to maintain competitiveness in world markets virtually all policy evaluations of this conflict have been limited by a significant misspecification in existing models none of the available computable general equilibrium cge models for international trading patterns consistently reflect the effects of environmental resources on consumers preferences the purpose of this paper is to report the first generation of a composite nonmarket and cge model nm cge for the european community the united states japan and a single region for the rest of the world the model incorporates the morbidity and mortality effects of particulates sulfur oxides and nitrogen oxides it uses existing nonmarket valuation estimates freeman with a specification for consumer preferences that allows changes in atmospheric emissions to diffuse in different amounts to

do prices and attributes explain international differences in food purchases food purchases differ substantially across countries we use detailed household level data from the united states france and the united kingdom to i document these differences ii estimate a demand system for food and nutrients and iii simulate counterfactual choices if households faced prices and nutritional characteristics from other countries we find that differences in prices and characteristics are important and can explain some difference e g united states france difference in caloric intake but generally cannot explain many of the compositional patterns by themselves instead it seems an interaction between the economic environment and differences in preferences is needed to explain cross country differences jel d12 i12 l11 l66 q11 food purchases differ across countries within countries over time and across demographic groups these differences seem to be correlated with rates of excess weight gain and diet related illness economists tend to attribute the difference in food purchases across markets to differences in prices an alternative explanation is that they are due to inherent differences in preferences and eating habits in this article we study the differences in food purchases and nutritional outcomes across countries focusing on the united states united kingdom and france we start by systematically documenting the differences in food purchases for consumption at home between the united states united kingdom and france we show that us households purchase different foods from french and uk households for example us households purchase more calories per person a greater percentage of those calories comes in the form of carbohydrates and a lower share in the form of proteins a higher share of expenditure is on drinks and prepared foods and

toward a theory of agency and altruism in family firms surprisingly the majority of u s family firms offer employed family members short and long term performance based incentive pay we draw on the household economics and altruism literatures to explain why family firms might feel compelled to do so and develop theory that predicts when this practice will be beneficial results based on data obtained from 883 family firms show that altruism as reflected by the parents estate and share transfer intentions moderates the effect of these pay incentives as our theory predicts as such this article helps explain both how altruism influences agency relationships in family firms and why business practice in family firms differs from those found in other types of firms

problems in the measurement of consumer cost of living indexes three empirical issues in the use of cost of living indexes are examined a substitution bias b differences across demographic groups and c the importance of the reference indifference curve for true indexes when preferences are nonhomothetic using the estimated parameters of a demand system for food commodities from two microdata cross sections both true parametric and laspeyres price indexes for food are compared across both demographic groups and cross sectional cohorts

the correlates of entrepreneurship in three types of firms the objective of the research was to discover the chief determinants of entrepreneurship the process by which organizations renew themselves and their markets by pioneering innovation and risk taking some authors have argued that personality factors of the leader are what determine entrepreneurship others have highlighted the role played by the structure of the organization while a final group have pointed to the importance of strategy making we believed that the manner and extent to which entrepreneurship would be influenced by all of these factors would in large measure depend upon the nature of the organization based upon the work of a number of authors we derived a crude typology of firms simple firms are small and their power is centralized at the top planning firms are bigger their goal being smooth and efficient operation through the use of formal controls and plans organic firms strive to be adaptive to their environments emphasizing expertise based power and open communications the predictiveness of the typology was established upon a sample of 52 firms using hypothesis testing and analysis of variance techniques we conjectured that in simple firms entrepreneurship would be determined by the characteristics of the leader in planning firms it would be facilitated by explicit and well integrated product market strategies and in organic firms it would be a function of environment and structure these hypotheses were largely borne out by correlational and multiple regression analyses any programs which aim to stimulate entrepreneurship would benefit greatly from tailoring recommendations to the nature of the target firms

the logic of testing structural change in meat demand a methodological analysis and appraisal in the past two decades the profession has expended valuable resources testing structural change in meat demand with mixed results overlooked to date is a fundamental methodological problem that transcends all methods of testing for structural change in this study a methodological framework is used to show that there is no valid test of structural change because of this result additional criteria from the methodology literature are used to evaluate the literature on structural change in meat demand and to provide suggestions for fertile areas of future research

the second engel law is it a paradox abstract the second engel law says that the engel curve for food moves out as family size increases thus showing a decrease in welfare what is puzzling though is that this regularity does not hold for equivalent income functions expressed in per capita terms deaton and paxon 1998 economies of scale household size and the demand for food journal of political economy 106 5 897 930 show that holding per capita total household expenditure constant per capita expenditure on food falls with the number of heads deaton and paxson s empirical evidence from developed and less developed countries seems to invalidate the claim of the second engel s law the main objective of this paper is to understand such paradoxical relationship between food consumption and household size our nonparametric empirical evidence drawn from the colombian 1985 urban survey shows that the food share is negatively related to total household per capita expenditure in line with deaton and paxson s claim but equivalent incomes shift to the right as theory predicts the regularity of our nonparametric results is an indication of a problem in the parametric specification of the engel curve modified by family size in fact using also the surveys of italy nepal djibouti and bangladesh we show that a theoretically plausible modified engel curve is coherent with the claim of the second engel law and explains deaton and paxson s paradox

social interactions and habit formation in a model of female labour supply this paper investigates the influence of habit formation and preference interdependence on labour supply behaviour of married females a novelty of the paper is that we incorporate direct survey information on reference groups of individuals in a neoclassical labour supply model for that purpose we first estimate a latent variables model relating the direct information to the true but unobserved reference groups one of the most interesting features of the model is that the presence of young children becomes an insignificant factor in the hours equation while it remains a significant factor in the participation decision in addition the labour supply curve is much flatter in a model with habit formation and preference interdependence than in a model without it both habit formation and preference interdependence contribute significantly to the explanation of female labour supply 1998 elsevier science s a all rights reserved

economies of scale in the household puzzles and patterns from the american past i introduction in one example of economies of scale households with multiple members are able to achieve the same standard of living at lower per capita expenditures on public goods than smaller households for example if two adults unite to form one household the couple will be better off as they can share public goods such as housing lowering per capita expenditure on them the couple can funnel these savings into increased consumption of public goods more spacious housing than either could afford separately making each member better off than they were when they lived by themselves the basic idea has strong intuitive appeal living standards for households of different sizes could be equated with lower per capita expenditures for larger households who are able to economize on public goods household economies of scale are therefore fundamental to the measurement of living standards measuring the distribution of income the costs of children the extent of poverty and poverty thresholds necessitates an accounting for these economies of scale one difficulty with household economies of scale is that it can be difficult to estimate the size of the scale economy and household economies of scale are not as well defined as scale economies in production while economies of scale are a function of the size of the household the demand for goods and services generally derives from both household size and composition when researchers turned their attention to economies of scale in the household they overcame the problem of detection and measurement by concentrating on adult only households as in nelson 1988 measuring economies of scale for households where all members are the same type have identical tastes and are treated equally will not aid in the measurement of poverty the distribution of income and the costs of children where compositional heterogeneity matters a second difficulty lies in the income and substitution effects that scale economies have on private goods while both the income and substitution effects imply increased consumption of public goods the income and substitution effects work in opposite directions for private goods and it is not possible to know which effect will dominate unless we know more about the private good private goods that have low own and cross price elasticities and sizable income elasticities are goods whose consumption is likely to increase with household size the increased consumption of those private goods could be taken as a measure of household economies of scale where larger households are better off in terms of private consumption due to scale economies in public consumption using this insight deaton and paxson 1998 suggested that food would be a good choice for a private good where the income effect will dominate because food has few substitutes and they argue that substitution away from food will be less likely for households close to subsistence this implies that food expenditures should increase with household size the savings realized on public goods would be funneled to food a necessity that has few substitutes rather than increasing with household size deaton and paxson found that food expenditure per capita decreases with household size after considering and dismissing a number of possible explanations they conclude that their empirical results are a puzzle a literature analyzing this food puzzle has developed deaton and paxson 2003 gan and vernon 2003 gardes and starzec 2000 gibson 2002 gibson and kim 2007 horowitz 2002 perali 2001 vernon 2005 but research on household scale economies has yet to look at how or if scale economies change over time just as knowledge about scale economies at a point in time allows us to estimate the extent of poverty and inequality knowledge about changes in scale economies are useful for analyzing changes in living standards over time even more knowledge about changes in scale economies is important since average household size has changed over time

children and household economic behavior this paper looks at some of the methodological issues that arise in modeling the effects of children on household behavior and presents some estimates for selected areas for our purposes household behavior will be taken to refer to household decisions on labor supply the allocation of expenditure to different periods and the decision as to what to do with the difference between income and expenditure i shall be concerned mainly with the effects of dependent children and i restrict attention largely to western societies excerpt

the entrepreneurial orientation performance relationship in private family firms the moderating role of socioemotional wealth drawing on socioemotional wealth sew literature this paper revisits the established entrepreneurial orientation eo performance relationship in a family business context the main idea in entrepreneurship literature is that eo leads to increased firm performance we question this logic in a family business context because family related non financial goals like sew may prevent the firm to reap the fruits of their entrepreneurial efforts specifically we argue that sew engenders inefficiencies that place constraints on the realization of the benefits of entrepreneurship therefore we propose that a high level of sew preservation hinders the transmission of the family firm s eo into positive performance effects to test this hypothesis an empirical study was developed using a sample of 232 belgian private family firms robust linear regression analysis reveals that the positive effect of eo on financial performance decreases as the level of sew preservation increases

opening the black box of the relationship between hrm practices and firm performance a comparison of mne subsidiaries in the usa finland and russia this paper investigates the extent to which different human resource management hrm practices work better in different countries we also try to open the black box between hrm and multinational enterprise mne subsidiary performance by considering mechanisms through which hrm practices affect mne subsidiary performance the study utilizes a unique data set consisting of subsidiaries of 241 mnes operating in russia usa and finland in the partial least square analysis used to examine our hypotheses we demonstrate that different hrm practices are preferable in different countries and that motivation and ability are important mediating variables in the hrm mne subsidiary performance relationship

positive time preference the case for positive time preference is absolutely compelling unless there is an infinite time horizon with the expectation of unending technological advance combined with what we call drastically diminishing marginal utility this finding holds both in the positive and normative senses a corollary is that savings are interest elastic

gaids a generalised version of the almost ideal demand system abstract aids is a popular model in empirical demand literature in this paper a generalised version of aids gaids is presented estimated and statistically tested evidence from italian household data suggests rejection of aids also when demographic effects are considered

consumer welfare and climate change in greenland abstract this manuscript aims to assess the potential impact of climate change on consumer welfare in greenland an arctic economy that has been historically affected by climate variation three proxies for climate change i annual mass change anomaly of the ice cap ii annual temperature anomalies and iii annual heating degree days anomalies are used to test the hypothesis that climate is a potential determinant of consumer expenditure the quadratic almost ideal demand system in its original specification is used to test this hypothesis the empirical analysis supported by granger causality tests shows that the annual mass change anomaly of the ice cap is a statistically and economically significant determinant of consumption of non durable goods in greenland a counterfactual analysis predicts that climate change could have decreased the wealth of consumers with an aggregate cumulative social welfare loss of 2010 us 21 63 million between 2003 and 2017

food expenditures and household demographic composition in the us a demand systems approach food expenditures and subsistence quantities of poverty status and non poverty status us households are analysed within a linear expenditure system that postulates subsistence quantities to be linear combinations of demographic variables using the us bureau of labor statistics 1992 consumer expenditure survey and detailed monthly consumer price indices this article obtains expenditure elasticities own price elasticities and subsistence quantities for each income group across nine broadly aggregated food commodity groups elasticity estimates and subsistence quantity estimates differ across income groups supporting the premise that policies targeted at specific income groups should be based on the target group s elasticity estimates rather than average population elasticities parameter estimates are then used to simulate how subsistence quantities and own price elasticities can be expected to vary according to the demographic composition of the household within a specific income group

a unified approach to incorporating demographic or other effects into demand systems a general method of introducing demographic effects into any demand system using modifying functions is described which permits complicated interactions of demographic variables with prices and expeditures theorems give properties the modifying functions must have to ensure integrability of the resulting system demand equations of the new system are given explicitly as functions of the original demand equations and the modifying functions the procedure is interpreted as altering a households technology and is shown to encompass adult equivalent scales and related methods examples of modifying functions are derived and applications of the technique to uses other than demographic variation are considered excerpt

incorporating demand shifters in the almost ideal demand system abstract intercepts of share equations generally include demand shift variables in the almost ideal demand system and related models this results in estimates that depend on units of measurement solutions to this problem are identified and discussed

when votes are words not deeds some evidence from the nuclear freeze referendum according to our empirical results voting patterns in the nfr were consistent with the central thesis of an expressive model that moral expression dominates consequentialist behavior when choice is costless while consequentialist theory would predict that owners of capital would favor nuclear weapons capital owners could afford to vote contrary to their interests and in line with common morality because the costs of moral expression in the nfr were so low just as the capital ownership variables do not work in the direction predicted by our consequentialist model neither does income does this mean that wealthy voters cast votes diametrically opposed to their self interest not at all the expressive model contends that when voting is costless people do not have interests but rather moral judgments which now cost very little to express indeed when votes involve words not even individuals interests in government expenditure can be detected

testing a theory of exact aggregation this article analyzes the importance of exact aggregation restrictions and the modeling of demographic effects in jorgenson lau and stoker s 1982 model of aggregate consumer behavior these issues are examined at the household level using canadian cross sectional microdata exact aggregation restrictions and some implicit restrictions on household demographic effects are strongly rejected by our data these results do not preclude pooling aggregate time series data with cross sectional microdata to estimate a model of aggregate consumer behavior they do suggest however an alternative basis for the aggregate model

cost of characteristics indices and household equivalence scales abstract the ratio of cost functions of demographically different households is a true cost of demographic characteristics index this index is independent of a base level of income or utility ib if and only if it equals a ratio of household equivalence scales that are themselves ib this paper analyzes the restrictions on cost functions and commodity specific equivalence scales required for the existence of ib scales and indices since scales can be price dependent the restrictions on behavior are far less severe than for ordinary engel style household scales connections between ib scales and other techniques for incorporating demographic effects into demand systems are described

on impatience economic growth and the environmental kuznets curve a dynamic analysis of resource management the paper presents a dynamic analysis of natural resource management and investigates some key factors that affect optimal management and resource conservation using a recursive specification of time preferences we show how endogenous discounting and impatience can affect the motivation for both capital investments and environmental preservation we examine the relationships between economic growth and environmental quality endogenous discounting provides new insights in the economic dynamics underlying the environmental kuznets curve by treating growth as endogenous we examine how externalities and economic growth interact with each other we investigate how economic development can contribute to an increased demand for environmental preservation as an important new result we also show how poverty can contribute to environmental degradation

budget share demographic translation and the aggregate almost ideal demand system abstract this paper introduces budget share demographic translation in the almost ideal demand system aids and explores its implications for aggregation over consuming units it os shown that under certain conditions the joint distribution of expenditure and demographic characteristics plays an explicit role in the aggregate aids empirical evidence based on italian data is provided and the implied expenditure pattern for a number of combinations of expenditures and household characteristics derived from the estimated aggregate aids the empirical results suggest that the usual rejection of the homogeneity restriction in aggregate demand systems might have to do with the improper treatment of the aggregation issue

the welfare effects and the distributive impact of carbon taxation on italian households in this work the welfare effects and the distributive impact on italian households of the italian carbon tax are calculated the carbon tax has been introduced in italy at the beginning of 1999 asking for smooth increases over a number of years in the prices of most fossil fuels its welfare effects have been calculated using true cost of living index numbers and the compensating variation the parameters have been obtained through estimation of a complete almost ideal demand system using households data from 1985 to 1996 the welfare loss turns out to be quite substantial and affects italian households in a non negligible way but the distribution of welfare losses across different levels of total monthly expenditures does not allow sustaining the regressivity of carbon taxation as the effect becomes bigger as we move up the income distribution this evidence might encourage the use of carbon taxes at least in the transport sector as cost effective instruments of environmental policy especially after the ratification of the kyoto protocol on climate change

estimation of complete demand systems from household budget data the linear and quadratic expenditure systems in this paper we explore two issues in empirical demand analysis the estimation of complete systems of demand equations using household budget data section i and the incorporation of demographic characteristics into such systems section ii although there are numerous studies which use time series data to estimate complete demand systems and many which estimate engel curves from household budget data there are virtually none which combine budget data from different periods to estimate complete systems since each budget study corresponds to a single price situation one might conjecture that estimation of complete systems would not be possible unless budget studies were available from a large number of periods this is incorrect in section i we argue that interesting complete demand systems can be estimated from a small number of budget studies despite the limited price variability represented in such data to demonstrate this we use budget study data for two periods to estimate a pair of related demand systems the familiar linear expenditure system les and a quadratic expenditure system qes a generalization of les in which the demand equations are quadratic in total expenditure the inclusion of demographic variables in the analysis of household consumption patterns is desirable because there are likely to be systematic differences in the consumption behavior of households with different demographic characteristics but the effects of demographic characteristics have seldom been studied within the framework of complete demand systems in section ii we propose translating as a general method for incorporating demographic variables into complete systems of demand equations this method has not previously been discussed as a general technique for bringing demographic variables into demand systems although it has been employed in several studies to improve the estimates of the les and the qes presented in section i we reestimate these two systems using translating to incorporate family size

a sample selection model for prepared food expenditures the factors affecting household expenditures on four types of prepared food products from a sample selection model estimated using a two step method are explored results suggest that several variables affect household expenditures on various prepared food products factors examined are presence of children number of earners region household size seasonality age race education and income

environmental defensive expenditures and households behaviour in italy the paper explores the role of environmental defensive expenditures in the consumption behaviour of italian households environmental defensive expenditures are not borne to increase households welfare but to prevent or avoid the effects of a worsening environmental quality the literature on environmental accounting argues that economic growth in industrialized countries is accompanied by an increasing load of defensive activities that may lead to a reorientation of consumption behaviour in this work this hypothesis is tested using annual data on mean consumption expenditures of italian households from 1985 to 1996 a complete system of demand is estimated and short run price elasticities of demand for defensive expenditures are calculated the complete system of demand functions is specified using the quadratic almost ideal demand system proposed by banks blundell and lewbel results show that there is very low substitution between the demand for the six aggregate goods in which total expenditure is
