long run welfare under externalities in consumption leisure and production a case for happy degrowth vs unhappy growth in this paper we contribute to the debate on the relationship between growth and well being by examining an endogenous growth model where we allow for externalities in consumption leisure and production we analyze three regimes a decentralized economy where each household makes isolated choices without considering their external effects a planned economy where a myopic planner fails to recognize both leisure and consumption externalities but recognizes production externalities and a planned economy with a fully informed planner we first compare the balanced growth paths under the three regimes and then we numerically investigate the transition to the optimal balanced growth path we provide a number of findings first in a decentralized economy growth or labor or both are greater than in the regime with a fully informed planner and hence are sub optimal from a welfare standpoint second a myopic intervention which overlooks consumption and leisure externalities leads to more growth and labor than in both the decentralized and the fully informed regime third we provide a case for happy degrowth a transition to the optimal balanced growth path that is associated with downscaling of production a reduction in private consumption and an ongoing increase in leisure and well being

farm productivity and rural poverty in india armed with new data we return to an old question from the pages of this journal to what extent do india s rural poor share in agricultural growth combining data from 24 household sample surveys spanning 35 years with other sources we estimate a model of the joint determination of consumption poverty measures agricultural wages and food prices we find that higher farm productivity brought both absolute and relative gains to poor rural households a large share of the gains was via wages and prices though these effects took time the benefits to the poor were not confined to those near the poverty line

poverty decline agricultural wages and non farm employment in rural india 1983 2004 the authors analyze five rounds of national sample survey data covering 1983 1987 8 1993 4 1999 0 and 2004 5 to explore the relationship between rural diversification and poverty poverty in rural india declined at a modest rate during this period the authors provide region level estimates that illustrate considerable geographic heterogeneity in this progress poverty estimates correlate well with region level data on changes in agricultural wage rates agricultural labor remains the preserve of the uneducated and also to a large extent of the scheduled castes and scheduled tribes although agricultural labor grew as a share of total economic activity over the first four rounds it had fallen back to the levels observed at the beginning of the survey period by 2004 this all india trajectory masks widely varying trends across states during this period the rural non farm sector grew modestly mainly between the last two survey rounds regular non farm employment remains largely associated with education levels and social status that are rare among the poor however casual labor and self employment in the non farm sector reveal greater involvement by disadvantaged groups in 2004 than in the preceding rounds the implication for poverty is not immediately clear the poor may be pushed into low return casual non farm activities due to lack of opportunities in the agricultural sector rather than being pulled by high returns offered by the non farm sector econometric estimates reveal that expansion of the non farm sector is associated with falling poverty via two routes a direct impact on poverty that is likely due to a pro poor marginal incidence of non farm employment expansion and an indirect impact attributable to the positive effect of non farm employment growth on agricultural wages the analysis also confirms the important contribution to rural poverty reduction from agricultural productivity availability of land and consumption levels in proximate urban areas

the economic impacts of climate change evidence from agricultural output and random fluctuations in weather fisher et al 2012 hereafter fhrs have uncovered coding and data errors in our paper deschenes and greenstone 2007 hereafter dg we acknowledge and are embarrassed by these mistakes we are grateful to fhrs for uncovering them we hope that this reply will also contribute to advancing the literature on the vital question of the impact of climate change on the us agricultural sector fhrs main critiques of dg are as follows i there are errors in the weather data and climate change projections used by dg ii the climate change projections are based on the hadley 2 model and scenarios rather than the more recent hadley 3 model and scenarios iii standard errors are biased due to spatial correlation iv the inclusion of state by year fixed effects does not leave enough weather variation to obtain meaningful estimates of the relationship between agriculture profits and weather v storage and inventory adjustment in response to yield shocks invalidate the use of annual profit data and vi fhrs argue that a better specified hedonic model produces robust estimates unlike the results reported in dg four of these critiques have little basis and we respond to them here in the introduction specifically with respect to ii the more recent daily climate predictions were not available when we wrote dg nevertheless the most important issue is providing the reliable estimates of climate change and in this note we report estimates based on the climate model we used in dg and a more recent one that we gained access to in the meantime iii in the primary table on agricultural profits dg reports two sets of standard errors with the first clustered at the county level and the second based on a variance covariance matrix that accounts for spatial correlation using the method proposed in conley 1999 thus the claim of fhrs 2012 seems overblown nevertheless to ease comparisons of papers in this literature this note will adopt the fhrs convention of reporting estimated standard errors clustered at the county and state levels we find that inference is largely unaffected by the choice between these different assumptions about the variance covariance matrix

distributional implications of climate change in rural india a general equilibrium approach we develop a general equilibrium framework based on a specific factors trade model to quantify the medium term household welfare impacts of global warming in rural india using an hedonic approach grounded in the theory combined with detailed microdata we estimate that three decades of warming will reduce agricultural productivity in the range of 7 13 with the arid northwest of india especially hard hit our analysis shows that the proportional welfare cost of climate change is likely to be both modest and evenly distributed across percentiles of the per capita income distribution but this latter conclusion emerges only when the flexibility of rural wages is taken into account

strategic information manipulation in duopolies abstract this paper studies a duopoly market in which firms can draw inferences concerning uncertain market demand from observations of their outputs and market price firms may adjust their outputs away from myopically optimal levels to affect the informativeness of the market price because firms quantities are observed firms can manipulate the extent to which belief revision occurs rather than the direction in which beliefs are revised as in signal jamming models we develop conditions and present examples under which the value of information is positive and negative and under which firms will increase or decrease quantity to manipulate information journal of economic literature classification numbers d80 l13

choosing the joneses endogenous goals and reference standards a growing economic literature stresses the importance of relative comparisons e g for savings and consumption or happiness in this literature it is usually assumed that reference standards against which people compare themselves are exogenously given in contrast findings from social psychology suggest that people play an active role in determining their reference standards we introduce a social comparison model where people choose their reference standards to serve motives of self improvement and self enhancement the model predicts that reference standards increase in individuals abilities and that people thus tend to compare themselves to similar others the results of a questionnaire study confirm the prediction of the model

food prices wages and welfare in rural india this paper considers the welfare and distributional consequences of higher relative food prices in rural india through the lens of a specific factors general equilibrium trade model applied at the district level the evidence shows that nominal wages for manual labor both within and outside agriculture respond elastically to increases in producer prices that is wages rose faster in rural districts growing more of those crops with large price run ups over 2004 09 accounting for such wage gains the analysis finds that rural households across the income spectrum benefit from higher agricultural commodity prices indeed rural wage adjustment appears to play a much greater role in protecting the welfare of the poor than the public distribution system india s giant food rationing scheme moreover policies like agricultural export bans which insulate producers as well as consumers from international price increases are particularly harmful to the poor of rural india conventional welfare analyses that assume fixed wages and focus on households net sales position lead to radically different conclusions

inequality and growth in the presence of competition for status abstract we investigate a simple endogenous growth model where agents care about their social status as greater equality tends to provide greater incentives to differentiate oneself redistribution may increase wasteful competitive consumption and lead to lower growth

the impact of global warming on agriculture a ricardian analysis reply we measure the economic impact of climate on land prices using cross sectional data on climate farmland prices and other economic and geophysical data for almost 3 000 counties in the united states we find that higher temperatures in all seasons except autumn reduce average farm values while more precipitation outside of autumn increases farm values applying the model to a global warming scenario shows a significantly lower estimated impact of global warming on u s agriculture than the traditional production function approach and in one case suggests that even without co sub 2 fertilization global warming may have economic benefits for agriculture 16 refs 5 figs 5 tabs

class systems and the enforcement of social norms abstract we analyze a model in which there is socially inefficient competition among people in this model self enforcing social norms can potentially control the inefficient competition however the inefficient behavior often cannot be suppressed in equilibrium among those with the lowest income due to the ineffectiveness of sanctions against those in the society with the least to lose we demonstrate that in such cases it may be possible for society to be divided into distinct classes with inefficient behavior suppressed in the upper classes but not in the lower

a curvature condition ensuring uniqueness of cournot equilibrium with applications to comparative statics abstract we study a curvature condition on demands that with a cost assumption ensures the uniqueness of cournot equilibrium for two firms the condition is that industry marginal revenue rises no faster than price falls the condition is weaker with more firms and holds for any smooth demand curve provided there are enough firms

social status education and growth this paper investigates the implications of social rewards on the allocation of talent in society and consequently on the process of economic growth we consider two sources of heterogeneity among workers nonwage income and innate ability a greater emphasis on status may induce the wrong individuals that is those with low ability and high wealth to acquire schooling causing workers with high ability and low wealth to leave the growth enhancing industries this crowding out effect taken alone discourages growth growth may be enhanced by a more egalitarian distribution of wealth which reduces the demand for status

joint determination of food consumption and production in rural sierra leone estimates of a household firm model abstract this paper investigates the determination of food consumption for rural households in sierra leone that produce the foods which they consume a household firm model is estimated with seven commodities including five foods non foods and labor as compared to three commodities in past studies such food disaggregation permits tracing of the effects of socioeconomic variables on household nutrient availability household specialization in production is such that censored data is a problem a tobit approach is used to correct for this for most crops the own price effects on consumption remain negative when a price change is allowed to shift the budget constraint by effecting the profits from home production elasticities of calorie availability with respect to toal expenditure are found to be sizeable varying little by expenditure group the price elasticities of calorie availability are generally positive however an important exception occurs for price of the staple food rice this exception has several important policy implications which are explored

downscaling heterogeneous household outcomes in dynamic cge models for energy economic analysis abstract downscaling methods for dynamic computable general equilibrium models are developed and analyzed the methods produce outcomes for a variety of different household types by downscaling the aggregate quantities from an economic growth model with a representative household this approach uses household survey data and long term population projections for different household types to compare the performance of the downscaling methods vs a general equilibrium model with multiple household groups under a variety of conditions including demographic change technological change and a carbon tax both recursive dynamic and forward looking downscaling methods produce results that approximate well a multiple household model run the recursive dynamic downscaling method is applied to an illustrative example estimating impacts of a carbon tax on aggregate co 2 emissions and the energy demand of different household groups for a middle of the road development scenario

economic and social class voting in a model of redistribution with social concerns we investigate how concerns about social status may affect individuals preferences for redistribution in our model agents are heterogeneous across two dimensions productivity and social class and an individual s social status is de ned as his relative standing in terms of a weighted average of these two components the weight on each component depends positively on its standard deviation redistribution thus simultaneously affects labor supply and the weights that determine social status as such taxation not only redistributes resources from the rich to the poor but also becomes a way of preserving or modifying social status thus individuals who have the same productivity but belong to different social classes support different tax rates we characterize the equilibrium of the political game as the solution of a system of non linear equations and identify the interclass coalition of voters who support the equilibrium tax rate

tariff pass through and the distributional effects of trade liberalization abstract this paper estimates the distribution of welfare gains due to the trade reforms in india by simultaneously considering the effect on prices of tradable goods and wages the cost of consumption for each household is affected by the domestic price changes while wage incomes adjust to these price changes in equilibrium three rounds of the indian employment and consumption surveys are used for the analysis the price transmission mechanisms are estimated for both rural and urban areas to understand the extent to which the trade reforms are able to affect the domestic prices in order to assess the distributional effects a series of nonparametric local linear regressions are estimated the findings show that households at all per capita expenditure levels had experienced gains as a result of the trade liberalization while the average effect was generally pro poor and varied significantly across the per capita expenditure spectrum

using survey data to assess the distributional effects of trade policy the author develops and applies a methodology to empirically explore the effects of trade policies on the distribution of income and poverty in developing countries he uses a methodology based on two links one connecting trade policies to prices and another connecting prices to household welfare the author applies the methodology to the study of the distributional effects of mercosur on argentine families the main finding is that mercosur benefits the average argentine household across the entire income distribution there is evidence of a pro poor bias of the regional trade agreement on average poor households gain more from the reform than middle income households whereas the effects on rich families are positive but not statistically significant prior to the reform argentine trade policy protected the rich over the poor and after the reform granted some protection to the poor as relative pre mercosur tariffs are higher on relatively skill intensive goods the tariff removals tend to benefit the poor over the rich these findings indicate that trade reforms may actually help improve the distribution of income and reduce poverty in the country

booming sector and de industrialisation in a small open economy this paper presents a theoretical analysis of the dutch disease the phenomenon whereby a boom in one traded goods sector squeezes porfitability in other traded goods sectors both by directly bi

tax reform and welfare measurement do we need demand system estimation the exact measurement of the welfare costs of tax and price reform requires a detailed knowledge of individual preferences typically first order approximations of welfare costs are calculated avoiding detailed knowledge of substitution effects the authors derive second order approximations which unlike first order approximations require knowledge of the distribution of substitution elasticities this paper asks to what extent simple approximations can be used to measure the welfare costs of tax reform and evaluates the magnitude of the biases for a plausible size tax reform in the authors empirical examples first order approximations display systematic biases second order approximations always work well

de growth and welfare in an equilibrium model with heterogeneous consumers this paper studies equilibrium growth and voluntary degrowth allowing for heterogeneous and time varying preferences the approach is based on applying a dynamic equilibrium model with externalities in production consumption and leisure preference heterogeneity regarding status competition is modeled by asymmetric consumption externality parameters whereas heterogeneity regarding voluntary simplicity is incorporated by allowing for agent specific restrictions on maximum consumption equilibrium is studied in terms of a balanced growth path bgp numerical examples suggest that degrowth triggered by voluntary simplicity by a subset of consumers less affected by status competition has a positive effect on the aggregate welfare under externalities in consumption and leisure a reduction in status competition increases the aggregate welfare and reduces the equilibrium growth rate simulations suggest that a time varying equilibrium in the heterogeneous preference model with two consumer classes is well approximated by a constant bgp

the stability of the cournot oligopoly model a reassessment abstract the stability properties of the cournot oligopoly model are examined for the continuous adjustment process sufficient conditions for instability are established which are shown to be of significance when the number of firms n is small local and global stability are shown under appropriate conditions which for global stability include the restriction n 5 the proof of global stability corrects a well known proof by f hahn rev econ stud 29 1962 329 331 results for the discrete time adjustment process are reported and the restrictiveness of the model s assumptions are discussed

why isn t growth making us happier utility on the hedonic treadmill abstract a preference structure is constructed grounded in psychological evidence with well being a function of the consumption level and the growth of the variety of goods consumed such preferences are analyzed in an endogenous variety growth model the implications are consistent with the increase in income and the variety of goods consumed in developed economies in the post war period that have not been accompanied by an increase in reported well being moreover the results suggest a connection between the stagnancy of reported well being and diminishing returns in technological change despite an increase in the variety of goods available over time

comparative statics for oligopoly demand shift effects when demand rises in an imperfectly competitive industry price output profits consumer surplus and welfare may individually rise or fall the possibilities are thus broader than with either a demand shift under competition or a cost shift in either typ e of industry systematic relationships are established showing howe ver that the pattern of effects cannot be arbitrary imperfect compe tition is necessary for profits to fall when demand rises profits alw ays rise with either perfect competition or perfect collusion this a gain contrasts with the cost shift case where imperfect competition is not necessary for perverse profit effects copyright 1988 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

rice prices and income distribution in thailand a non parametric analysis rice is a staple crop in thailand significantly entering both household production and consumption this paper examines the effect of rice prices on the distribution of real income across households taking into account household characteristics and geographical location the data set is a large scale survey of 11 893 households simple nonparametric techniques for regression and density estimation are used these methods depend on few assumptions and generate flexible graphical results that are directly informative about the problem at hand the main results are that higher rice prices should benefit all rural households but the largest benefits accrue to rural households in the middle of the income distribution copyright 1989 by royal economic society

when are nash equilibria independent of the distribution of agents characteristics author s bergstrom ted varian hal r abstract we present examples of nash equilibria that do not vary with the distribution of a parameter across agents and then offer a general theorem that characterizes this independence

veblen effects in a theory of conspicuous consumption the authors examine conditions under which veblen effects arise from the desire to achieve social status by signaling wealth through conspicuous consumption while veblen effects cannot ordinarily arise when preferences satisfy a single crossing property they may emerge when this property fails in that case budget brands are priced at marginal cost while luxury brands though not intrinsically superior are sold at higher prices to consumers seeking to advertise wealth luxury brands earn strictly positive profits under conditions that would with standard formulations of preferences yield marginal cost pricing the authors explore factors that induce veblen effects and they investigate policy implications copyright 1996 by american economic association

status effects and negative utility growth this paper explains the observed stagnation of happiness measures through a growth model in which agents care about conspicuous consumption normal goods confer direct utility while status goods confer utility only at the expense of others firms can improve the quality of both goods through r d the nash equilibrium of the consumer game results in the share of expenditure on status goods increasing with the number of times the status good has been improved as the economy grows resources for innovation are transferred entirely to status good r d the resulting long run rate of utility growth is negative

on the existence of cournot equilibrium this paper examines the existence of n firm cournot equilibrium in a market for a single homogeneous commodity it proves that if each firm s marginal revenue declines as the aggregate output of other firms increases which is implied by concave inverse demand then a cournot equilibrium exists without assuming that firms have nondecreasing marginal cost or identical technologies also if the marginal revenue condition fails at a potential optimal point there is a set of firms such that no cournot equilibrium exists the paper also contains an example of nonexistence with two nonidentical firms each with constant returns to scale production
