growth with equity for the development of mexico poverty inequality and economic growth 1992 2008 summary this paper constitutes an attempt to determine the relative contribution of changes in economic growth and in the distribution of income to changes in poverty in mexico our findings clearly indicate that growth with redistribution lower income inequality was the key to reducing poverty continuously and in an important manner during 2000 2006 however after 2006 decreasing per capita income coupled with the persistently high inequality gini of 52 caused the reversal of the favorable trend observed since 1996 raising poverty to pre 2002 levels consequently it is argued that for mexico a middle income country exhibiting quite low growth rates and high inequality levels the further improvement in its distribution of income and assets is essential if the economy is to succeed in making a real dent in poverty for that purpose the implementation of an active pro poor growth policy should be strongly encouraged

regional earnings differences in great britain evidence from the new earnings survey hemmings p j 1991 regional earnings differences in great britain evidence from the new earnings survey reg studies 25 123 133 previous analysis comparing earnings between regions of great britain has concentrated upon the earnings of male employees using a large micro data base this paper takes a broader approach by examining earnings differences for female and part time employees as well as male employees human capital models are used to explain the variation in earnings in terms of characteristic differences and reward effects a restricted model with no regional element is tested against more general models which allow for regional variation in the constant term only and in both the constant and coefficients of the equations the most general model indicates that equations for the earnings of males display greater regional heterogeneity than those for females whilst the south east of england is the most distinctive region in terms of employee characteristics and in the returns to those e

what is a relationship worth repeated exchange and the development and deployment of relational capital organization scholars have highlighted the value of relationships in fostering effective exchange suggesting that repeated exchange creates a relational asset with latent value derived from elevated social connections norms and simple expectations of exchange continuity yet the empirical evidence supporting such claims remains largely indirect as a consequence few studies have been able to directly examine how contextual factors shape the accumulation of this relational asset or define its value in application we directly measure the value of relationships between suppliers and a large buyer using the buyer s choices in internet enabled procurement auctions to estimate the degree to which stronger relationship histories with suppliers increase willingness to pay for high volume commodity like parts our setting also allows us to examine how this willingness to pay for relationships is shaped by the social context in which they develop and by the exchange context in which they are subsequently depl

foreign exchange equivalence and project appraisal procedures this paper investigates the implications of different adjustment mechanisms for shadow pricing traded and nontraded goods in a flexible price model a foreign exchange equivalent rule that can be readily adapted whatever the adjustment mechanism is derived it is shown that traded commodities are always valued at border prices and nontraded commodities can always be shadow priced in terms of changes in production and consumption of traded goods valued at border prices the role of the shadow exchange rate and the implications for measuring the balance of payments effect when no tax adjustment policy is assumed are also discussed copyright 1990 by royal economic society

green transition of energy systems in rural china national survey evidence of households discrete choices on water heaters abstract energy systems in rural china are experiencing a transition from traditional fossil fuels to renewables this paper aims to investigate the potential factors that influence the choices of rural residents regarding water heaters with a focus on the low carbon transition to solar water heating systems to this end a face to face questionnaire survey is undertaken with 3404 rural households randomly selected among 12 representative provinces a comprehensive set of discrete choice modelling approaches were used the empirical results show that 1 sociodemographic variables have significant effects on residents first stage choice of a water heater to buy or not to buy but few effects on the second stage decision to choose electric lpg or solar water heaters which type to buy 2 information spillover is important to facilitate the usage of water heaters particularly of solar products 3 the electricity price which is regulated at a very low rate has no apparent effect on the choice of solar water heaters 4 government subsidy has a significant effect in the first stage but no differentiated effect on the decision choice in the second stage policy and managerial implications are presented to speed up the ongoing low carbon transition of energy systems in china

is individual environmental consciousness one of the determinants in transport mode choice this article models negative impact on the environment as one of the attributes of transport mode by this modelling we are able to examine whether individual environmental consciousness of this impact plays a significant role in his her choice of transport mode a survey data from saito and onohara area in northern osaka of japan is used to estimate the model with the heteroscedastic extreme value specification both of the estimated and simulated results imply that individual environmental consciousness does influence his her decision on transport mode choice in the sample furthermore the likelihood ratio tests indicate that both the utility and scale parameters are not equivalent across sub samples of university commuters research facility commuters and residents the results of the comparison across sub samples suggest that sometimes we may learn more from sub dividing a whole sample into several sub samples if we could distinguish them by their characteristics

regional wage differentials and the spatial convergence of worker characteristic prices this paper provides a test for variation in wage structures across regions the authors suggest that the appropriate test for structural variation incorporates a combination of two lines of research structural variation and compensating variation the model of earnings determination used implies that while job characteristic prices may be subject to stochastic shocks or industry specific factors and hence may differ between regions the returns to human capital characteristics will be regionally invariant the results suggest that the theoretical expectations of regional homogeneity is generally supported for the decade of the 1970s copyright 1989 by mit press

testing producer perceptions of jointly beneficial best management practices for improved water quality this paper examines producer perceptions of jointly beneficial relationships among best management practices for improved water quality identifying producer tendencies to bundle these types of practices may increase adoption and lower the costs of voluntary adoption programmes particularly those relying on dissemination of information unlike previous studies perceived changes in environmental quality as well as perceived changes in profits are used to define jointly beneficial inputs the econometric model used in the analysis demonstrates that two of the three management practices considered are perceived to be jointly beneficial

are citizens willing to pay for agricultural multifunctionality agricultural multifunctionality is the recognition of the joint exercise of economic environmental and social functions by the agricultural sector in order to make the concept operative for the design of public policies it is necessary to estimate the social demand for such functions the main objective of this article is to present an empirical application in this sense for this purpose we have adopted the agricultural system of cereal steppes in tierra de campos in spain as a case study the economic valuation technique used is the choice experiment the results suggest the existence of a significant demand for the different functions although the demand is heterogeneous depending on the socioeconomic characteristics of the individuals surveyed

relative shadow prices and the shadow exchange rate abstract the divergent conclusions that have been reached in the literature as to the role of the shadow exchange rate in project appraisal are reconciled in this paper it is shown that the shadow exchange rate is not needed to assess the relative shadow prices of either traded or nontraded goods

early warning systems and systemic banking crises in low income countries a multinomial logit approach abstract this paper estimates an early warning system ews for predicting systemic banking crises in a sample of low income countries in sub saharan africa since the average duration of crises in this sample of countries is longer than one year the predictive performance of standard binomial logit models is likely to be hampered by the so called crisis duration bias the bias arises from the decision to either treat crisis years after the onset of a crisis as non crisis years or remove them altogether from the model to overcome this potential drawback we propose a multinomial logit approach which is shown to improve the predictive power of our ews compared to the binomial logit model our results suggest that crisis events in low income countries are associated with low economic growth drying up of banking system liquidity and widening of foreign exchange net open positions

alternative models of earnings determination and labor market structures there are three distinct research traditions in the analysis of individual earnings determination human capital or earnings function analyses aggregate wage analyses and labor demand analyses an important and incongruous aspect of each is the treatment of geographical differences in labor markets this paper first investigates the magnitude and character of geographical wage differentials the sizable differences discovered there are then related to the existing and highly simplified models of labor market differences while the two major classes of models compensating differentials and labor demand differ significantly in assumptions and implications it is impossible to distinguish adequately between them there appears to be a clear need for more structural analyses of labor market operations

project appraisal procedures and the evaluation of foreign exchange different procedures for evaluating foreign exchange have been suggested in the project appraisal manuals of unido and little and mirrlees while it is widely agreed that the manuals differ in their practical procedures there has been disagreement as to whether they are equivalent in principle using a model due to boadway we show that the manuals differ in principle the little mirrlees procedure can be given an interpretation which correctly values traded and non traded goods in project appraisal while the unido formula for the shadow exchange rate is not required when the balance of payments constraint is binding

the willingness to pay for the health care under taiwan s national health insurance system in this study we utilized the nested multinomial logit model to estimate the willingness to pay wtp values for different national health insurance nhi coverage plans in taiwan the wtp value for having care from clinics in a hospital care only hco plan is nt 178 us 6 per person month the wtp value for having care from hospitals in a clinic care only cco plan is nt 1342 us 43 per person month the wtp value for the nhi with a universal coverage uc is nt 1540 us 49 per person month the figure nt 1540 us 49 is equivalent to 8 77 of monthly household income much higher than the new premium rate of the new nhi tax 2 5 4 of monthly household income proposed by the taiwan s government our result suggests that taiwan s government may increase the new premium rate further in order to make taiwan s nhi financially more sustainable

discrete choice models with multiple unobserved choice characteristics since the pioneering work by daniel mcfadden utility maximization based multinomial response models have become important tools of empirical researchers various generalizations of these models have been developed to allow for unobserved heterogeneity in taste parameters and choice characteristics here we investigate how rich a specification of the unobserved components is needed to rationalize arbitrary choice patterns in settings with many individual decision makers multiple markets and large choice sets we find that if one restricts the utility function to be monotone in the unobserved choice characteristics then up to two unobserved choice characteristics may be needed to rationalize the choices

characteristics of households in the informal sector of an emerging economy using the case study of trinidad and tobago we investigate the socio economic demographic and attitudinal characteristics of households that participate in the informal sector of an emerging economy and their perception of the risk of detection by tax authorities while doing so data are gathered from a cross sectional field survey covering 570 households results using multinomial logit and ordered probit models suggest that households are motivated to participate in the informal sector when members spend little time in formal sector activity believe that taxes are too high and their incomes are too low have dependents to support and believe that the resulting tax evasion will go undetected their perception of the risk of detection by the tax authority is determined largely by the income they earn in the formal sector and the extent of government bureaucracy prevailing there

self selection bias in the evaluation of voluntary energy conservation programs while voluntary energy conservation programs have been extensively promoted by electric utilities and public utility commissions their effectiveness has been insufficiently critiqued this paper contributes to the growing evaluation of such programs by measuring the net energy savings directly attributable to an actual set of programs the analysis explicitly corrects for the self selection bias that can arise in program evaluation the correction is found to be important traditional evaluation methods are subject to considerable bias correcting for this bias the amount of program induced energy savings is found to be considerably less than traditionally believed copyright 1988 by mit press

the importance of bundling in a gorman lancaster model of earnings the idea that the labor market of individuals can be decomposed into payments to separate productive attributes has an enduring appeal in economics assuming that demographic groups differ only in their endowments of productive characteristics it is possible to rationalize observed demographic earnings differentials without invoking the arguments that characteristics specific to a particular demographic group are direct objects of employer demand by aggregating skills over all demographic groups it is possible to produce a theory of the market determination of the prices of skills held in different amounts by different demographic groups this paper considers conditions under which characteristics are uniformly priced across sectors of a multisector economy the paper presents empirical evidence that rejects uniform pricing of characteristics as a description of the us labor market bundling may account for this evudence but other hypotheses do as well authors

project appraisal and foreign exchange constraints a comment a paper in this journal by blitzer dasgupta and stiglitz i98i hereinafter bds entitled project appraisal and foreign exchange constraints examines the implications of various non optimal macroeconomic adjustment policies for project evaluation the discussion is presented in terms of a simple two good one consumer economy with price distortions which lead the ratio of the domestic price of the exported good e to the domestic price of the imported good i to be greater than the internati onal price ratio it is argued that the resulting trade gap will force the government to pursue an adjustment policy which may take the form of taxation of income or commodities rationing or foreign borrowing and it is shown that the choice of policy will determine the appropriate shadow price formulae to be used in project appraisal the view that world prices provide shadow prices for traded goods is argued to be correct for some but not all of the macroeconomic policies considered this comment argues that the bds analysis fails to specify how tax revenue is to be incorporated in the model as a result the various policy options open to the government are not clearly brought out we set out below in section i an amplified version of the bds general equilibrium model which includes tax revenue and use it to show how the different adjustment mechanisms have to be related to the public sector budget constraint in section ii we reconsider their analysis and show that if either an income or a commodity tax on the importable is used to ensure public sector balance then world prices remain shadow prices for traded goods in section iii we make the point that the presence of import tariffs does not imply in the context of a real general equilibrium model that the balance of payments constraint will be violated the conclusion is drawn that endogenous foreign borrowing cannot be analysed without respecifying the basic bds model our comment is confined to the problem of shadow pricing traded goods in the bds model we do not consider rationing as a means of macroeconomic adjustment policy nor do we comment on their section iii where they analyse the additional problems which follow from introducing a non traded commodity into the model

accounting for south non south real wage differentials and for changes in those differentials over time a unified accounting framework for analyzing differences in real wages between the south and non south in 1979 and for changes in south non south wage ratios between 1973 and 1979 is outlined cross section analysis of real wage differentials allows two sources of regional wage variation 1 worker and job characteristics and 2 returns to those characteristics our results suggest that differences in the latter may be as important in accounting for regional wage differentials as the former an interactive specification permits decomposition of changes in regional wage ratios into direct effects of changes in characteristics and indirect effects of region year and region year variations in returns more than half the predicted changes in south non south wage ratios can be accounted for by changing relative returns to characteristics between the south and non south

public funding of environmental amenities contingent choices using new taxes or existing revenues for coastal land conservation alternative funding approaches affect stated preferences an individual s willingness to reallocate existing tax dollars exceeds willingness to pay new taxes to conserve land however stated preferences also imply a non zero opportunity cost to existing tax dollars different income groups reveal statistically equivalent marginal utilities both for income and for reallocating tax dollars yet individuals with lower income show a relatively larger increase in their willingness to support land conservation when the choice shifts from new taxes to reallocation of existing tax dollars the paper encourages consideration of equity implications that may be obscured when analysts focus on willingness to pay

property rights regimes in complex fishery management systems a choice experiment application the tonle sap wetland fishery was previously divided into 3 different management zones for conservation open access fishing and private fishing rights to the private fishing zone involved auctions for exclusive rights to temporarily designated plots this paper aims to explore the auction based system by investigating how this fishery management system affects different groups of small scale fishermen and how different characteristics of the fishing lots affect the bidding a choice experiment approach was used to model fishermen s choices in a hypothetical auction market by offering fishermen the choice between purchasing different potential fishing lots and a no purchase option implying fishing only in the communal fishing grounds the preferred latent class model with two segments of fishermen showed that the bidding behavior of the more privileged group out competes the other group irrespective of the lot characteristics this result suggests that it is unlikely that the redesign of the auction system itself would be an effective way of securing access to fishing resources for the two observed groups of fishermen this implies that open access fishing grounds and or other regulations may also be needed in future management as they serve an important role for the poorer segments

a comparison of choice based multinomial and nested logit models the family structure and welfare use decisions of divorced or separated women home based work differs from other employment because the work site is the home itself this difference means that the fixed costs of working at home are less than the fixed costs of working on site and that home based workers may engage in joint market

parental wealth and first time homeownership a cohort study of family background and young adults housing situation in sweden this paper investigates whether family background seems to have any influence on first time homeownership recent studies have indicated that it has become more difficult to become established in the housing market and such situations may increase the importance of parental wealth in this study parental wealth is estimated as family background information on parents homeownership father s socioeconomic status and single parenting unique cohort data for three birth cohorts suggest that there is a significant cohort effect in young adults tenure decision furthermore the results imply that parents homeownership has become a more important predictor of the transition to first time homeownership for those young adults facing increasing problems in the housing market

amenities and regional differences in returns to worker characteristics average wages in regions in the united states vary considerably in trying to explain these differences in the average wage across regions a number of studies have found that differences in the returns to characteristics of workers such as years of schooling are as important as differences in the skill composition of the labor force 4 6 10 141 these differences in returns are generally interpreted as reflecting regional differences in demand for worker characteristics coupled with barriers to factor mobility this interpretation is based on the argument that the presence of at least one perfectly mobile factor with perfect information will cause spatial convergence in characteristic prices as that particular factor exploits any spatial price differential 4 p 2161 this paper suggests an alternative to this demand based explanation for regional differences in the structure of wages one based on regional differences in the supply of worker characteristics this explanation does not rely on impediments to the movement of workers or firms and is consistent with an equilibrium view of wages in which regional wage differentials are viewed as compensation for local amenities the theoretical model presented in the following section assumes capital and labor are perfectly mobile with perfect information implying that in equilibrium the utility of workers with similar characteristics is the same in all locations this convergence of utility however does not necessarily imply convergence of characteristic prices equilibrium differences in the returns to a specific worker characteristic can exist if worker characteristics affect an individual s valuation of an area s amenities relative to the individual s demand for land

shadow prices for project evaluation under alternative macroeconomic specifications for purposes of social cost benefit analysis a project may be viewed as a disturbance to the economy displacing it from some initial equilibrium to a new one but the new configuration will depend on which particular variables adjust to restore equilibrium this paper examines the shadow prices for project evaluation under alternative assumptions about how equilibrium is restored when the government reacts by altering its foreign exchange reserves the shadow prices coincide with those advocated in the manuals on social cost benefit analysis however if the government adjusts its domestic expenditures or tariff rates the shadow prices will differ from those of the manuals except insofar as the relative shadow prices of tradeables remain their relative border prices the paper first presents the model followed by two cases in which domestic prices and wage rates do not vary because ad valorem tariffs are fixed and one case in which they are endogenous

convergent validity of attribute based choice questions in stated preference studies the application of attribute based choice questions is well established in the marketing literature but there are unique aspects of the design that warrant investigation to assess their validity for economic welfare estimation three design issues are investigated in this paper 1 the placement of the monetary stimulus policy cost to respondents in the sequence of attributes 2 the number of policy alternatives respondents are asked to consider in choice questions two versus three and 3 the inclusion versus exclusion of a status quo alternative in choice questions the data used to implement these investigations are from a survey designed to estimate the value maine residents place on a farmland conservation easement program tests of convergent validity indicate that the placement of the monetary stimulus first versus last in the list of attributes did not affect estimates of preference parameters significant differences between questions with three versus two alternatives did occur and the inclusion exclusion of a status quo alternative did not affect preference parameters

local industrial dominance and earnings attainment drawing on the ecological concept of local industrial dominance we examine how the industrial distribution of the metropolitan labor force influences workers earnings industrial dominance is defined as the proportional overrepresentation of the local labor force in a given industry or industrial sector a contextual analysis of census microdata for the largest 125 smsas shows that within industries and sectors workers in metropolitan areas in which their industry is dominant have significantly higher earnings than workers in areas in which that industry is less dominant these results holdfor two different measures of dominance andfour racelsex groups the effects of local dominance on earnings appear stronger for industries in the core and state sectors for financial business and personal service functions andfor public administration the influence of dominance is partly explained by the tendency of locally dominant industries to be composed of larger establishments

choice of contracts in the british national health service an empirical study following major reforms of the british national health service nhs in 1990 the roles of purchasing and providing health services were separated with the relationship between purchasers and providers governed by contracts using a mixed multinomial logit analysis we show how this policy shift led to a selection of contracts that is consistent with the predictions of a simple model based on contract theory in which the characteristics of the health services being purchased and of the contracting parties influence the choice of contract form the paper thus provides evidence in support of the practical relevance of theory in understanding health care market reform

re employment probabilities of unemployment benefit recipients this article studies transitions out of unemployment for benefit recipients in spain we analyse the duration of unemployment distinguishing between spells that end in recall workers returning to the previous employer and spells that end in exit to a new job this distinction allows us to find that the recall hazard rate increases around the time of exhaustion of benefits however this happens only for workers receiving unemployment insurance ui because we are unable to replicate this result for workers receiving unemployment assistance ua we believe the finding lends support to the hypothesis that in spain firms and workers make a strategic use of ui

compensating differences and interregional wage differentials interregional differences in average wages and earnings have been observed particularly in the north and south of the united states ever since the mid 1800s that observation has motivated several empirical attempts to determine the source of those differentials measured both in nominal and real terms and to explain why they have been maintained over time the general conclusion reached by the overwhelming majority of these studies is that the labor market has not eliminated these wage differentials even in the face of substantial interregional migration this result has at least two alternative interpretations first it would appear to contradict the theory of compensating differences as applied to the labor market thaler and rosen 1975 which stresses that under the assumptions of perfect information free geographic and intersectoral labor mobility and homogeneous consumer tastes the nominal wage rates of workers who have similar human capital characteristics live and work in similar environments and experience similar living costs are driven to equality second this result may only reflect an aggregation error in other words there may be several types of labor that are each paid different equilibrium wage rates and comprise different percentages of the workforce in each region even if the real wage paid to each class of workers is interregionally invariant a situation that instead would support the theory of compensating differences failure to distinguish accurately between labor types could produce the illusion of a wage differential this paper considers the two alternative interpretations given above as to why interregional wage differentials might exist hedonic real wage equations are estimated for four regions of the united states using observations on individual household heads drawn from the 1976 panel study in income dynamics psid this sample is of interest because the 1976 psid data contain unusually detailed measures of education work experience and occupation as well as information on workplace and job characteristics thus a more complete specification of the wage equation is permitted and the possibility of aggregation error is reduced particularly in comparison with other interregional wage differential studies several of these studies for example have been based on aggregate data from the census of manufactures fuchs and perlman 1960 gallaway 1963 scully 1969 and coelho and ghali 1971 which provide no direct measurements on the human capital of workers the remainder of the discussion is organized into three sections section ii specifies the wage equation and describes the psid data section iii then reports empirical results which are consistent with the findings based on aggregate data of bellante 1979 and coelho and ghali 1971 in that they support the theory of compensating differences more specifically for full time workers the rewards to attributes relevant in determining real wages apparently are interregionally invariant however because this result conflicts with most previous research on interregional wage differentials based on aggregate data and virtually all such research based on microdata welch 1966 hanoch 1967 hanushek 1973 1981 hirsch 1978 and sahling and smith 1983 a number of empirical comparisons are made between the present study and the approaches taken by other investigators conclusions and implications are drawn out in section iv

statistical testing of bounded rationality with applications to the newsvendor model abstract in this paper we define bounded rationality in terms of probabilistic cost efficiency this establishes a framework where bounded rationality can be examined rigorously by statistical methods we apply this theory to data from laboratory experiments on the newsvendor model we enter into a theoretical discussion of the classical pull to center effect and explain why underorders are typically larger than overorders

an alternative approach to the analysis of wage differentials a key question in many studies of male female or black white wage differentials is how much of the differential can be explained by economic factors and how much remains unexplained the unexplained portion is then ascribed to discrimination since oaxaca 17 first formalized this decomposition the residual difference methodology has been the dominant methodology utilized in empirical studies of wage differentials 4 7 8 10 15 18 but recently the validity of the assumptions underlying the residual difference methodology have been called into question by butler 5 6 in this paper the theoretical underpinnings of the residual difference methodology are reexamined and an alternative theoretical framework for this methodology is suggested the new framework overcomes the shortcomings inherent in oaxaca s specification of the model and therefore provides a sound theoretical foundation for the residual difference decomposition

valuing financial health and environmental benefits of bt cotton in pakistan data from a farm survey and choice experiment are used to value the benefits of bt cotton in pakistan unlike previous research on the economic impacts of bt which mostly concentrated on financial benefits in terms of gross margins we also quantify and monetize positive externalities associated with technology adoption due to lower chemical pesticide use on bt cotton plots there are significant health advantages in terms of reduced incidence of acute pesticide poisoning and environmental advantages in terms of higher biodiversity and lower soil and groundwater contamination these positive externalities are valued at us 79 per acre of which half is attributable to health and the other half to environmental improvements adding average gross margin gains of us 204 results in an aggregate benefit of us 283 per acre of bt or us 1 7 billion for the total bt cotton area in pakistan

towards a new early warning system of financial crises abstract this paper develops a new early warning system ews model based on a multinomial logit model for predicting financial crises it is shown that commonly used ews approaches which use binomial discrete dependent variable models are subject to what we call a post crisis bias this bias arises when no distinction is made between tranquil periods when economic fundamentals are largely sound and sustainable and crisis post crisis periods when economic variables go through an adjustment process before reaching a more sustainable level or growth path we show that applying a multinomial logit model which allows distinguishing between more than two states is a valid way of solving this problem and constitutes a substantial improvement in the ability to forecast financial crises the empirical results reveal that for a set of 20 open emerging markets for the period 1993 2001 the model would have correctly predicted a large majority of crises in emerging markets

employment and child care choices in canada and the united states in this paper we examine employment and child care choices of two parent families with young children in the united states and canada using a pooled data set based on recent national surveys in each country we find that the employment and child care choices of canadian families are similar to those of u s families estimates of a model of employment and child care choices indicate significant effects of child care subsidies child care prices and wage rates on employment and child care choices however none of these factors helps to explain the differences in employment and child care choices between the two countries ce memoire examine le choix de l emploi et du soin des enfants dans les familles ou il y deux parents aux etats unis et au canada en utilisant des donnees d etudes recentes dans les deux pays il appert que les choix des familles canadiennes sont semblables a ceux des familles americaines les calibrations d un modele de ces choix montrent les effets significatifs des subventions au soin des enfants du prix des soins des enfants et des taux de salaires sur ces choix cependant aucun de ces facteurs n explique les diffrences dans les patterns de choix entre les deux pays

quantifying the effects from horizontal mergers comments on the underlying assumptions in our paper published in this issue we measured the effects of the proposed volvo scania merger we first estimated an oligopoly model with product differentiation and then used the parameter estimates to compute the post merger equilibrium and the implied price and welfare changes under various alternative scenarios in section 4 4 of our paper we discussed what we view as the most important sources of concern regarding our empirical analysis in part based on the comments from the experts hired by volvo during the case the hausman leonard hl paper elaborates in more detail on the specific points raised by the experts during the case in this note we respond to these points

external sector closing rules in applied general equilibrium models abstract this paper examines formulations of external sector behavior adopted in some of the recent applied general equilibrium models in many cases these models are constructed for single economies and the model builder attempts to use a convenient external sector specification to close the model issues and difficulties with export demand and import supply functions for foreigners which satisfy trade balance and the modeling of small economy price taking behavior are explored

the equity efficiency trade off in environmental policy evidence from stated preferences the design of environmental policy raises several equity issues in particular the distribution of benefits and costs at the same time it has often been argued that there is a trade off in environmental policy between equity and efficiency which brings these issues firmly to the attention of environmental economics in this paper we use a simple choice experiment to elicit individual preferences over equity efficiency trade offs in the context of two environmental problems local air pollution and global climate change we find that equity matters to people as much as efficiency does in the design and delivery of environmental policy

e business usage across and within firms in the uk profitability externalities and policy using data from the third uk community innovation survey we model the usage of e business across and within firms in the uk in the year 2000 as a single observation upon an integrated process of inter and intra firm diffusion the intra firm dimension is a significant extension to standard analysis the model estimates indicate that the pattern of e business usage reflects the heterogeneity of firms in terms of size other innovative activity and labour force skills generating differences in the payoffs to use as well as market and non market intermediated externalities the policy implications of the findings are discussed c 2008 elsevier b v all rights reserved

do two earner households base their choice of residential location on both incomes this article focuses on the role of individual incomes in the residential location decisions of two earner households conventional studies often treat households as a black box and describe them by a single utility function the article raises the question is the household utility paradigm an adequate framework for understanding the location decisions of two earner households it tests an implication of the household utility paradigm the income pooling hypothesis for location decisions the results provide evidence for rejecting the hypothesis among childless families but fail to provide evidence for rejecting it when children are present the results raise the need to address intrahousehold dynamics in modelling location decisions
