beyond gdp the quest for a measure of social welfare this paper critically examines the various approaches to the measurement of individual well being and social welfare that have been considered for the construction of alternatives to gdp special attention is devoted to recent developments in the analysis of sustainability in the study of happiness in the theory of social choice and fair allocation and in the capability approach it is suggested in the conclusion that although convergence toward a consensual approach is not impossible for the moment not one but three alternatives to gdp are worth developing jel i31 e23 e01

rational household labor supply traditionally household behavior is derived from the maximization of a unique utility function in this paper we propose an alternative approach in which the household is modeled as a two member collectivity taking pareto efficient decisions the consequences of this assumption are analyzed in a three good model in which only total consumption and each member s labor supply are observable if the agents are assumed egoistic i e they are only concerned with their own leisure and consumption it is possible to derive falsifiable conditions upon household labor supplies from both a parametric and nonparametric viewpoint if alternatively agents are altruistic restrictions obtain in the nonparametric context useful interpretation stems from the comparison with the characterization of aggregate demand for a private good economy

marriage market divorce legislation and household labor supply this paper provides a theoretical framework for analyzing the impact of the marriage market and divorce legislation on household labor supply in our approach the sex ratio in the marriage market and the rules governing divorce are examples of distribution factors these factors are defined as variables that affect the household members bargaining position but not preferences or the joint budget set we extend the collective labor supply model developed by chiappori to allow for distribution factors we show that our model imposes new restrictions on the labor supply functions and eases the identification of individual preferences and the intrahousehold decision process the model is estimated using psid data for the year 1988 our results do not reject the restrictions imposed by the model also the sex ratio and divorce laws deemed favorable to women are found to affect labor supply behavior and the decision process in the directions predicted by the theory and to have sizable effects

collective labor supply a single equation model and some evidence from french data in chiappori s 1988 collective model of labor supply hours of work are supposed flexible in many countries however male labor supply does not vary much in that case the husband s labor supply is no longer informative about the household decision process and individual preferences to identify structural components of the model additional information is needed we thus consider an approach in which the wife s labor supply is expressed as a function of the household demand for one specific good we demonstrate that the main properties of chiappori s initial model are preserved and apply our results on french data

collective labor supply and household production this paper emphasises the importance of incorporating household production into the collective model of the household and considers how and to what extent the results of chiappori 1992 can be extended to this case this abstract was borrowed from another version of this item

introducing household production in collective models of labor supply in a recent paper chiappori 1992 i proposed a model of labor supply based on a collective representation of household behavior in this framework each household member is characterized by his or her own utility function and decisions are only assumed to result in pareto efficient outcomes i showed that these simple assumptions were sufficient to i generate testable restrictions on labor supply functions and ii recover individual preferences and the outcome of the decision process from observed behavior for the sake of simplicity the results were derived in the simplest possible case namely a static labor supply model with private consumptions such a framework was appropriate only for the purpose of the paper that is a preliminary exploration of the properties of collective models of labor supply the next step is to evaluate the robustness of the results to various extensions of the basic model this opens a general research program and generates a wide range of particular problems that it is hoped will be considered in the future among the most serious shortcomings of the 1992 model is the absence of household production as in most labor supply models agents were assumed to divide their time between market activities and leisure as apps and rees 1997 in this issue very rightly point out in their comment the absence of domestic production is far from innocuous as soon as welfare issues are considered for instance a low level of market labor supply will automatically be interpreted as a large consumption of leisure whereas it may in fact reflect the specialization of one of the members in domestic

family time use leisure home production market work and work related travel this study analyzes the two person gronau type neoclassical model of the household where time use for each person is divided into three basic activities market work home production and pure leisure plus work related travel time the latter is treated as predetermined one contribution of this paper is that the economics of the gronau model is made clear and a complete comparative static analysis is provided a second contribution is that the model is subjected to a rigorous empirical test using data that permits the division of time into its four primary components most data sets do not permit this our empirical results do not accord well with the model s predictions or with previous findings by gronau in addition our results suggest that work related travel has an important influence on family time use

comprehensive nnp social welfare and the rate of return we show that growth in nnp measured in constant prices indicates welfare improvement provided that an observable rate of return measure is positive this is an alternative welfare interpretation of growth in comprehensive nnp compared with that of asheim and weitzman asheim b g weitzman m l 2001 does nnp growth indicate welfare improvement economic letters 73 233 239 which is based on a divisia consumer price index

agricultural household models extensions applications and policy this book presents the basic model of an agricultural household that underlies most of the case studies undertaken so far the model assumes that households are price takers and is therefore recursive the decisions modeled include those affecting production and the demand for inputs and those affecting consumption and the supply of labor comparative results on selected elasticities are presented for a number of economies the empirical significance of the approach is demonstrated in a comparison of models that treat production and consumption decisions separately and those in which the decisionmaking process is recursive the book summarizes the implications of agricultural pricing policy for the welfare of farm households marketed surplus the demand for nonagricultural goods and services the rural labor market budget revenues and foreign exchange earnings in addition it is shown that the basic model can be extended in order to explore the effects of government policy on crop composition nutritional status health saving and investment and to provide a more comprehensive analysis of the effects on budget revenues and foreign exchange earnings methodological topics primarily the data requirements of the basic model and its extensions along with aggregation market interaction uncertainty and market imperfections are discussed the most important methodological issues the question of the recursive property of these models is also discussed

collective labor supply heterogeneity and nonparticipation in this paper we extend the collective model of labour supply developed by chiappori 1988 to allow for discrete choices censoring and nonparticipation in employment we derive the collective restrictions on labour supply functions that we contrast with restrictions implied by the usual unitary framework we apply our results to the estimation of a collective labor supply model for married couples without children using uk data from 1979 to 1993 taking into account unobserved heterogeneity we use the log linear labor supply framework the implications of the unitary framework are rejected while those of the collective approach are not the estimates of the sharing rule show that wages have a strong influence on bargaining power within couples

welfare measurement under threats of environmental catastrophes abstract welfare measures under threats of environmental catastrophes are studied using the parable apparatus of weitzman and lofgren on the welfare significance of green accounting as taught by parable j environ econ manage 32 1997 139 153 the occurrence probability of the catastrophic events is driven at least partly by anthropogenic activities such as natural resource exploitation without external effects the green nnp is a genuine welfare measure vis a vis a particular parable economy often however the occurrence hazard constitutes a public bad treated as an externality by agents who ignore their own contribution to its accumulation in such cases the green nnp although accounting for the event hazard rate per se fails to properly internalize future effects on the hazard rate of current economic activities and as a result overestimates welfare the bias term associated with the green nnp is derived and expressed in a simple and interpretable form

pollution and politician productivity the effect of pm on mps applying methods of textual analysis to all 119 225 speeches made in the canadian house of commons between 2006 and 2011 we establish that air pollution reduces the speech quality of canadian members of parliament mps exposure to fine particulate matter concentrations exceeding 15 g m3 causes a 2 3 reduction in the quality of mps speech equivalent to a 2 6 month decrease in education for more difficult communication tasks the decrement in quality is equivalent to the loss of 6 5 months of schooling our design accounts for the potential endogeneity of exposure and controls for many potential confounders including individual fixed effects

collective female labour supply theory and application this article deals with female labour supply in the collective framework it studies married couples and starting from the empirical observation that the husband s labour supply is generally fixed at full time it shows that in this case structural elements of the decision process such as individual preferences or the rule that determines the intra household distribution of welfare can be identified if household demand for at least one commodity together with the wife s labour supply is observed these theoretical considerations are followed by an application using french data

collective labour supply heterogeneity and non participation we present identification and estimation results for the collective model of labour supply in which there are discrete choices censoring of hours and non participation in employment we derive the collective restrictions on labour supply functions and contrast them with restrictions implied by the usual unitary framework using the large changes in the wage structure between men and women in the u k over the last two decades we estimate a collective labour supply model for married couples without children the estimates of the sharing rule show that male wages and employment have a strong influence on bargaining power within couples

time allocation within the family welfare implications of life in a couple a collective model of leisure demand generalised to the production of a household public good is estimated on the british household panel survey the sharing rule is identified by using an original parametric framework based on the change of family status from single living to couple or from couple to single living womens ratios of private household expenditures are 40 on average the level of intra household inequality appears highly dependent on the intra household wage gap omitting household production in the model would overestimate the ratio by 7 percentage points on average

flows of air pollution ill health and welfare we provide a theoretical framework for measuring welfare when pollution influences economic growth by impairing health and driving up defensive medical expenditures we demonstrate the usefulness of our framework in practice by applying it to data from swedish valuation studies designed according to the accounting principles suggested here we estimate that the negative health effects of nitrogen dioxide emissions amount to 0 6 of gdp in sweden we also show that a corrective pigouvian tax should internalize the direct disutility reduced labor productivity and increased healthcare expenditures caused by pollution according to our calculations harmful health impacts alone excluding ecosystem effects justify 65 of the current swedish tax on nitrogen dioxide

sustainability and technical progress a rigorous model connects together the following three basic concepts 1 sustainability meaning the generalized future power of an economy to consume over time 2 green nnp meaning a current measure of national income that subtracts off from gnp not just depreciation of capital but also more generally depletion of environmental assets evaluated at current efficiency prices 3 technological progress meaning a projection onto the future of the so called solow residual a simple general formula is derived some crude calculations suggest a possibly strong effect of the residual which hints that our best present estimates of long term sustainability may be largely driven by predictions of future technological progress

environment health and human capital in this review we discuss three major contributions economists have made to our understanding of the relationship between the environment and individual well being first in explicitly recognizing how optimizing behavior particularly in the form of residential sorting can lead to nonrandom assignment of pollution economists have employed a wide range of quasi experimental techniques to develop causal estimates of the effect of pollution second economic research has placed a considerable focus on the role of avoidance behavior which is an important component for understanding the difference between biological and behavioral effects of pollution and for proper welfare calculations lastly economic research has expanded the focus of analysis beyond traditional health outcomes to include measures of human capital including labor supply productivity and cognition our review of the quasi experimental evidence on this topic suggests that pollution does indeed have a wide range of effects on individual well being even at levels well below current regulatory standards given the importance of health and human capital as an engine for economic growth these findings underscore the role of environmental conditions as an important factor of production jel i12 i31 j24 q51 q53

three sides of harberger triangles prevailing economic wisdom is highly critical of injudicious tax policies or government regulations uncorrected externalities unchecked monopolistic practices and various other market failures when economists are challenged to quantify the economic costs of associated price distortions it is standard practice and has been since the 1960s to use a small number of assumptions and selected elasticities to estimate areas of the relevant harberger triangles this simple and straightforward exercise has numerous applications and the virtue of producing answers rather than conjectures harberger triangles come in many shapes and sizes figure 1 offers an illustration of such a triangle for the simple case of an excise tax point a of figure 1 at which the demand and supply schedules intersect denotes market equilibrium in the absence of the tax with quantity q1 transacted at price p1 introduction of an excise tax at rate t payable by firms selling the commodity shifts the supply schedule upward by t at the new market equilibrium firms sell q2 units of the commodity at a market price of p2 receiving after tax p3 a p2 0 t market equilibrium at point a in figure 1 has the feature that marginal consumption benefits equal marginal production costs the excise tax drives a wedge between marginal benefits and marginal costs at consumption level q2 consumers are willing to pay any amount up to p2 for additional units of the good and suppliers would readily provide additional units of the good for any price of p3 or greater but these additional transactions do not take place due to the effect of the tax wedge the loss associated

implementing carbon credits for forests based on green accounting abstract this paper presents a carbon accounting method for forests that is implementable in the sense that it makes use of observable information the valuation of the effects of carbon dioxide is based on asset values rather than rental values with minor differences due to the treatment of such accidents as fires and pestilence the method corresponds to the flow method of the physical carbon accounting literature the stock change method of carbon accounting however is incompatible with economic principles rather than set carbon values to their optimal levels in the pigovian tradition we use current societal standards we also present a discussion of how to implement the scheme in the face of uncertainty

social accounting and welfare measurement in a growth model with human capital this paper addresses social accounting and welfare measurement in an economy where human capital is an important factor in the economic system human capital accumulation depends on the time consumers spend in education however human capital is also a separate argument in the production function facing firms which gives rise to a production externality in a command optimum where the externality is internalized we show that an augmented nnp measure is the appropriate welfare indicator we also discuss the taxtransfer system required for the decentralized economy to reach a command optimum

the role of technological progress in testing adjusted net savings evidence from oecd countries abstract in this paper we investigate the relationship between comprehensive measures of savings and changes in future consumption in oecd countries this relationship is at the basis of the interpretation of adjusted net savings as a weak sustainability indicator and so evidence of its validity provides support to the use of this indicator we construct various measures of comprehensive savings for 20 oecd countries to include depletion from non renewable resources human capital investment and technological progress given their importance especially for rich countries we focus on the role of technical progress and human capital in the form of changes in education level we do not find strong evidence in favor of including green adjustments in the conventional net savings however we find compelling evidence for the inclusion of technological progress since this involves a forward looking term the above result suggests that to construct an indicator of weak sustainability from conventional net savings some estimate of future technological progress is needed

global welfare comparisons to provide a normative foundation for transfers between dierent economies one needs information on their per capita welfare this paper considers various methods for doing this and reaches the following main conclusions i such global welfare comparisons are more demanding than usually thought ii the ranking of methods diers from that of local e g over time comparisons with real comprehensive per capita nnp being the least impractical method the lesson is that global welfare comparisons should be performed with great care the comparisons must be made in local real prices calculated according to purchasingpower parity where non traded environmental amenities play an important role

backward and forward looking shadow prices in inclusive wealth accounting an example of renewable energy capital abstract attaching weights to the list of capital assets is crucial in inclusive wealth accounting and sustainability assessments these weights or shadow prices can be constructed in theory by looking prospectively at future social profits that the capital in question is expected to yield in practice however both backward and forward looking shadow prices are used this study confirms that these two approaches are theoretically equivalent under strong assumptions and reviews how and why the two approaches are taken the two approaches are then applied to renewable energy capital rec which has rarely been done in either produced or natural capital accounting and sustainability assessments renewable energy capital provides an ideal example with which to compare the two approaches as it is a class of produced capital that substitutes both produced and natural capital the numerical results of both approaches demonstrate that renewable energy capital starts to account for as large a share as natural capital does if not produced capital or inclusive wealth in those countries where natural capital is poorly endowed and investment in renewable energy capital has been witnessed

the effect of language on economic behavior evidence from savings rates health behaviors and retirement assets languages dier widely in the ways they encode time i test the hypothesis that languages that grammatically associate the future and the present foster future oriented behavior this prediction arises naturally when well documented eects of language structure are merged with models of intertemporal choice empirically i nd that speakers of such languages save more retire with more wealth smoke less practice safer sex and are less obese this holds both across countries and within countries when comparing demographically similar native households the evidence does not support the most obvious forms of common causation i discuss implications for theories of intertemporal choice

selection on observed and unobserved variables assessing the effectiveness of catholic schools in this paper we measure the effect of catholic high school attendance on educational attainment and test scores because we do not have a good instrumental variable for catholic school attendance we develop new estimation methods based on the idea that the amount of selection on the observed explanatory variables in a model provides a guide to the amount of selection on the unobservables we also propose an informal way to assess selectivity bias based on measuring the ratio of selection on unobservables to selection on observables that would be required if one is to attribute the entire effect of catholic school attendance to selection bias we use our methods to estimate the effect of attending a catholic high school on a variety of outcomes our main conclusion is that catholic high schools substantially increase the probability of graduating from high school and more tentatively attending college we find little evidence of an effect on test scores

national accounts and environmental resources in the paper optimal growth theory is used to derive the appropriate definition of the net national product concept when there are environmental resources and environmental damage to take into account the basic conclusions are that conventional defined np should be corrected by deducting environmental damage and adding the value of the net change of all resources

inefficiency of male and female labor supply in agricultural households evidence from uganda this article analyzes the efficiency of the intra household allocation of female and male labor inputs in agricultural production in a collective household model spouses optimal on farm labor supply is such that the marginal rate of technical substitution between male and female labor is equated over different crops using the uganda national household survey 2005 06 we test whether this condition holds by estimating production functions and controlling for endogeneity using a method proposed by gandhi navarro and rivers 2009 we find that women are less productive than men that there is more female labor input on low productivity parcels and that men are relatively more productive on female controlled plots compared with male controlled plots total farm output could be higher and pareto improvements could be possible if male labor was reallocated to female controlled plots and or female labor was reallocated to male controlled plots

labour supply household production and intra family welfare distribution abstract this paper demonstrates the importance in conceptual and empirical terms of incorporating household production in models of labour supply to avoid misleading results concerning the intra family distribution of income and behavioural responses to economic policy

the welfare economic theory of green national accounts this paper takes a critical look at the literature on green national accounts the problem studied is to find a linear index of economic variables that responds to perturbations in the same direction as social well being the thesis of a large literature that net national product which is a flow is that index in closed economies is shown in some interpretations to be simply false and in others to suffer from deep estimation problems it is argued that capital depreciation using shadow prices should certainly be included in national accounts but that the right welfare index is a comprehensive measure of wealth defined as the shadow value of an economy s stock of all capital assets it is shown that comprehensive wealth is usable as a criterion for policy evaluation as well as for determining sustainable economic development

consumer prices the consumer price index and the cost of living after presenting major findings and recommendations the cpi commission reiterates the estimate of a 1 1 percentage point per annum upward bias it rejects the contention that the bls already makes substantial corrections for quality change that quality improvements and new products accrue only to the rich and that procedures to make more extensive quality adjustments valuations of new products and adjustments for commodity and outlet substitution are impractical the bias in the cpi can be sharply reduced as the authors detail in this paper coauthors are ellen r dulberger robert j gordon zvi griliches and dale w jorgenson

taxation and the household abstract previous analyses of demand systems and the welfare effects of taxing male and female labour supplies suppress the analysis of household resource allocation by assuming a household utility function to analyse the implications of assuming this is not the case we construct a simple but fairly general model of household resource allocation and use the properties of the equilibrium of this model to characterise the effects of tax policy on individual utilities as determined by the household resource allocation process

a contribution to the theory of welfare accounting a kind of unified theory is proposed as a dynamic generalization of the standard consumer surplus methodology for evaluating welfare changes the unified theory allows rigorous dynamic welfare comparisons to be inferred between any two economic situations from just knowing current incomes and observing a short run market demand schedule essentially the change in present discounted future utility is exactly captured by the formula difference in current income plus consumer surplus this well known formula is thereby shown to cover a far wider class of welfare comparisons than is customarily treated in the textbook static case

social accounting and the public sector this article contributes to the theory of social accounting as such it tries to extend earlier literature on the welfare equivalence of the comprehensive net national product in two main directions both of which refer to the public sector one is by considering welfare measurement problems associated with public good provision and redistributive policy respectively when the public revenues are raised by distortionary taxes the other is by addressing the consequences of a federation like decision structure where independent tax and expenditure decisions are made both by the central government and by lower level governments

estimating the parameters of a household production function with joint products by estimating the parameters of a production function whose inputs consist of family time and market goods the authors offer some new microeconomic estimates of the value of production that takes place in the home and also examine the concept of joint production that is the degree to which time devoted to home production simultaneously serves as leisure they find evidence of substantial jointness between home production time and leisure the degree of which is greater for wives than for husbands and that both husband and wife possess human capital skills more productive in market work than in home work

collective labor supply and welfare the paper develops a general collective model of household labor supply in which agents are characterized by their own possibly altruistic preferences and household decisions are only assumed to be pareto efficient an alternative interpretation is that there are two stages in the internal decision process agents first share nonlabor income according to some given sharing rule then each one optimally chooses his or her own labor supply and consumption this setting is shown to generate testable restrictions on labor supplies moreover the observation of labor supply behavior is sufficient for recovering individual preferences and the sharing rule up to a constant finally the traditional tools of welfare analysis can be adapted to the new setting

a general approach to welfare measurement through national income accounting a framework is developed for analyzing national income accounting using a revealed welfare approach that is sufficiently general to cover both the standard discounted utilitarian and maximin criteria as special cases we show that the basic welfare properties of comprehensive national income accounting previously ascribed only to the discounted utilitarian case extend to this more general framework in particular under a wider range of circumstances it holds that real nnp growth or equivalently a positive value of net investments indicates welfare improvement we illustrate the applicability of our approach in the dasgupta heal solow model of capital accumulation and resource depletion

married with children a collective labor supply model with detailed time use and intrahousehold expenditure information we propose a collective labor supply model with household production that generalizes an original model of blundell chiappori and meghir 2005 in our model adults individual preferences not only depend on own leisure and individual private consumption of market goods they also depend on the consumption of domestic goods which are produced by combining goods bought on the market with individuals time we apply our model to new and unique data on dutch couples with children the data contains detailed information about the spouses time use and the intrahousehold allocation of all expenditures our application uses a novel estimation strategy that builds upon the familiar two stage allocation representation of the collective model we obtain interesting and plausible empirical results spouses preferences depend on the consumption of domestically produced goods including children s welfare in addition pareto weights depend on variables like the individual wages and the share in the household s nonlabor income finally and perhaps surprisingly we do not nd evidence that mothers care more for their children than fathers this paper draws on data of the liss panel of centerdata special thanks go to marika de bruijne and arthur van soest who helped to construct the questionnaire and to guillaume schollier

collective household labor supply nonparticipation and income taxation in this paper we adopt the usual assumptions of the collective approach i e individualism and efficiency to study household labor supply the theoretical innovation is 2 fold first we incorporate the decision to participate in the labor market in the initial setting second we abandon the assumption of linearity of the budget constraint we show that i structural elements such as preferences or the outcome of the decision process can be recovered and ii testable restrictions are generated from the observation of the household labor supplies we also examine for this model how to simulate the incidence of fiscal reforms

a test of the unitary and collective models of household labour supply this paper tests the unitary and the collective household labour supply models within a structural framework a nonlinear unrestricted household labour supply system is postulated and the set of parametric restrictions imposed by each model is derived our results generally reject the income pooling restrictions embodied in the unitary model also the symmetry of cross wage effects is rejected however the collective model is not rejected for groups with no pre school children

accounting for the wealth of nations the net versus gross output controversy and its ramifications there has been a longstanding controversy over the use of net versus gross measures of national product in accounting for economic growth most recently reflected in several papers which have examined the role of environmental variables it is argued in this paper that the two measures are not substitutes but complements which reveal different aspects of the growth process gross product is the correct output concept for estimating the structure of production while net product is the correct concept for measuring the welfare consequences of economic growth an alternative to the conventional solow growth accounting framework is then presented in which the change in national wealth is decomposed into its component elements copyright 1992 by the editors of the scandinavian journal of economics

benefit cost analysis of non marginal climate and energy projects conventional benefit cost analysis incorporates the normally reasonable assumption that the policy or project under examination is marginal among the assumptions this entails is that the policy or project is small so the underlying growth rate of the economy does not change however this assumption may be inappropriate in some important circumstances including in climate change and energy policy one example is global targets for carbon emissions while another is a large renewable energy project in a small economy such as a hydropower dam this paper develops some theory on the evaluation of non marginal projects with empirical applications to climate change and energy we examine the conditions under which evaluation of a non marginal project using marginal methods may be wrong and in our empirical examples we show that both qualitative and large quantitative errors are plausible

marital matching economies of scale and intrahousehold allocations we propose a novel nonparametric method to empirically identify economies of scale in multiperson household consumption we assume consumption technologies that define the public and private nature

dynamic cost benefit analysis of large projects the role of capital cost this paper derives a dynamic cost benefit rule for evaluating large projects we show that in addition to the conventional income and consumer surplus measures the rule also entails an extra term involving capital cost changes

market wages and youth crime to study the problem of widespread youth crime i analyze a timeallocation model in which consumers face parametric wages and diminishing marginal returns to crime the theory motivates an econometric model that i estimate using data from the national longitudinal survey of youth my estimates suggest that youth behavior is responsive to price incentives and that falling real wages may have been an important determinant of rising youth crime during the 1970s and 1980s moreover wage differentials explain a substantial component of both the racial differential in criminal participation and the age distribution of crime

collective decisions household production and labor force participation in this paper we generalize the collective model of household labor supply with domestic production to allow for the possibility of nonparticipation in the labor market we also relax the marketability assumption according to which domestic goods and market goods are perfectly substitutable our results are twofold first we show that the main structural components of the decision process can be retrieved from observed behavior second we estimate a system of market and domestic labor supply using the panel study of income dynamics and apply the theoretical results to recover the intra household sharing of resources

collective labour supply with children we extend the collective model of household behavior to allow for the existence of public consumption we show how this model allows the analysis of welfare consequences of policies aimed at changing the distribution of power within the household our setting provides a conceptual framework for addressing issues linked to the targeting of specific benefits or taxes we also show that the observation of the labor supplies and the household demand for the public good allow one to identify individual welfare and the decision process this requires either a separability assumption or the presence of a distribution factor

on the welfare significance of green accounting as taught by parable abstract green nnp is a national accounting concept that subtracts off from gnp not just depreciation of capital but also depletion of environmental assets for a time autonomous technology green nnp has a rigorous welfare interpretation as an exact measure of the economy s future power to consume the present paper extends the standard framework to cover the case of labor augmenting technological progress for this special case of time dependence a powerful conceptual parable applies it is as if the conclusion from a simple minded welfare story told by the standard neoclassical one sector growth model covers a far more general situation involving any number of different types of capital any convex production possibilities set and fully optimizing behavior implications and applications are discussed

sustainable growth with environmental spillovers in this paper we apply the approach of ramsey and koopmans to the problem of optimal and sustainable growth under plausible assumptions intertemporal neutrality implies that the optimal growth path is sustainable without the contrivance of a sustainability constraint the model is extended to cases involving environmental disamenities the solutions equivalently solve the problem of maximizing net national product adjusted for depreciation in natural capital and environmental effects green net national product in this framework is constant over time thus avoiding the paradox of declining sustainable income

labor supply home production and welfare comparisons abstract we consider the collective model of labor supply with marketable domestic production we first show that if domestic production is mistakenly ignored the collective indirect utility functions that are retrieved from observed behavior will be unbiased if and only if the retrieved from observed behavior will be unbiased if and only if the profit function is additive otherwise in the non additive case the direction and the size of the bias will depend on the complementarity substitutability of spouses time inputs in the production process we then show that even if domestic labor supply functions are not observed valid welfare comparisons are possible this identification result generalizes that in chiappori chiappori p a 1992 collective labor supply and welfare journal of political economy 100 437 467

a simple approach to investigate intrahousehold allocation of private and public goods abstract we adopt the collective approach to consumer behavior with egoistic agents and assume that household consumption is either private or public we then show that 1 household demand functions have to satisfy testable constraints and 2 some elements of the decision process can be retrieved from observed behavior these results are based on a conditional demand m demand framework in which household demand functions are directly derived from the individual marginal rates of substitution finally we present an empirical illustration of these theoretical results using the u s consumer expenditure survey

international comparisons of living standards by equivalent incomes we propose a measure of living standards for international comparisons based on gdp per capita the measure incorporates corrections for international flows of income labor risk of unemployment healthy life expectancy household demography and inequalities the method for comparing populations that differ in some non income dimension consists of computing the equivalent variation of income that would make each population indifferent between its current situation and a reference situation with respect to the non income dimension this is applied to 24 oecd countries the obtained ranking of countries differs substantially from the gdp ranking

the identification of unobservable independent and spousal leisure this paper is based on the idea that for each partner in a marriage there are two distinct types of leisure one type is each person s independent or private leisure and the other type is spousal leisure whose importance has long been emphasized in the literature of psychology while each type of leisure is unobservable only total leisure is observed it is shown that the recent collective models of the intrahousehold allocation initiated by chiappori can be extended to identify each type of leisure up to an additive constant in particular the effects of each member s wage household unearned income and extrahousehold environmental parameters on the independent and spousal leisure and on the sharing rule are fully identified the observational requirement here is the same as in other studies namely the observation of individual labor supply individual wages household unearned income one assignable good and consumption expenditure at the household level
