transfer behavior in the health and retirement study measurement and the redistribution of resources within the family recent work by a number of economists has opened a debate about the role played by intergenerational transfers using the new health and retirement study hrs we are better able to address the issues involved contrary to the current literature on bequests we do not find that parents give transfers equally to all children rather we find that in the case of inter vivos transfers respondents give greaterfinancial assistance to their less well off children than to their children with higher incomes financial transfers to elderly parents are also found to be negatively related to the potential recipient s income these results hold both for the incidence of transfers and for the amounts in addition we allow for unobserved differences across families by estimating fixed effect models and find our results to be robust to these specifications a comparison of the hrs transfer data to other survey data demonstrates that the hrs is potentially quite useful for research on transfer behavior

a coevolutionary framework for analysing a transition to a sustainable low carbon economy this paper proposes a coevolutionary framework for analysing a transition to a sustainable low carbon economy based on the coevolution of ecosystems technologies institutions business strategies and user practices within a multi level micro meso macro perspective this builds on and develops previous coevolutionary analyses of long term technological and industrial change and recent renewed interest within ecological economics on coevolutionary approaches previous work has analysed how the coevolution of technologies and institutions has led to the lock in of current high carbon energy systems and how the coevolution of physical and social technologies and business strategies has brought significant material and welfare benefits to the minority of the world s population living in industrialised countries the coevolutionary framework proposed here may be used to undertake 1 detailed empirical analyses at a micro meso level of the challenges relating to the innovation and adoption of particularly low carbon technologies 2 as a framework for analysing the multi level interaction of social and technological elements within potential transition pathways to a low carbon energy system 3 to assess the implications for economic growth and prosperity of a transition to a low carbon economy and 4 to assist in the development of more formal multi level evolutionary economic models

saving rates and poverty the role of conspicuous consumption and human capital poor families around the world spend a large fraction of their income consuming goods that do not appear to alleviate poverty while saving at low rates we suggest that individuals care about economic status and interpret this behaviour as conspicuous consumption intended to provide a signal about unobserved income we show that if human capital is observable and correlated with income then a signalling equilibrium in which poor individuals tend to spend a large fraction of their income on conspicuous consumption can emerge this equilibrium gives rise to an increasing marginal propensity to save that might generate a poverty trap

parental human capital investment and old age transfers from children is it a loan contract or reciprocity for indonesian families abstract this paper proposes two alternative models of intergenerational transfers linking parental investment in human capital of children to old age support the first model formulates these transfers as a pure loan contract and the second model as self enforcing reciprocity both models predict neutrality of intergenerational redistribution of resources within the family also known as the difference in income transfer derivatives property two models however provide different reasons for the failure of this property and yield different policy implications for parental human capital investment and provision of old age support specification tests on the indonesian family life survey data reject the pure loan model in favor of the reciprocity model the estimated difference in income transfer derivatives for this data is found to be significantly higher than the difference estimated by altonji hayashi and kotlikoff altonji et al 1992 altonji j g hayashi f and kotlikoff l j 1992 is the extended family altruistically linked direct tests using micro data the american economic review vol 82 5 1177 98 for the u s psid data

migration remittances and the family remittances by migrants along with migration itself are elements in a migrant familys intertemporal contractual arrangement the reasons why the migrant and his family voluntarily enter into a mutually beneficial contractual arrangement with each other rather than with a 3rd party are discussed and the conditions under which the contractual arrangement is self enforcing are identified both parties can usually benefit from a number of pareto efficient mutual contractual arrangements this gives rise to an indeterminacy problem solved through a bargaining process between the parties who consequently converge to a contractual arrangement implying a specific flow of migrant to family remittances the chosen contractual arrangement reflects the relative bargaining powers of the parties and variables impinging upon these powers thus bear upon remittances in the light of these arguments tests are conducted on observed remittance behavior across individual migrants in botswana authors

risk pooling between households and risk coping measures in developing countries evidence from rural bangladesh abstract using data from rural bangladesh i test whether income risks are pooled among villagers between neighboring households and between related households living in different villages i find evidence that risks to food consumption are pooled between neighboring households and between related households but not among villagers as for nonfood consumption i find little evidence of risk pooling except between unrelated neighboring households i also find that while households belonging to a neighborhood network do not take any special measures during an economic hardship those not belonging to any such network try to smooth consumption by selling off livestock and other assets and by getting interest free loans negative income shocks are found to have little effect on labor supply or private transfers

the role of intermediaries in low carbon transitions empowering innovations to unlock district heating in the uk abstract the literature on socio technical transitions considers how technological innovations can be established within the context of an incumbent regime that is often resistant or inflexible to change strategic niche management is an approach to catalysing a transition to a new regime using protected niche spaces to enable development and experimentation with an innovation intermediary actors play an important role in establishing these niches as they facilitate knowledge sharing and build the wider networks and systems needed to support an innovation the influence of intermediaries within socio technical transitions and strategic niche management is still an under researched area in this paper we use a decision theatre research process to collect empirical evidence from a range of local stakeholders involved in establishing new district heating projects in the united kingdom uk this method carried out in a group workshop format enables understanding of the interactions between stakeholders throughout the stages of the district heating development process the study suggests that intermediaries can play a role in supporting niche empowering processes the existing institutional framework surrounding intermediary actors and the geographical scale at which they work within that framework are shown to be influential on actors agency to choose their approach to empowering an innovation the work highlights the potential for intermediaries to support the restructuring of this institutional framework to enable more radical stretch and transform empowering activities

social comparisons and contributions to online communities a field experiment on movielens we design a field experiment to explore the use of social comparison to increase contributions to an online community we find that after receiving behavioral information about the median user s total number of movie ratings users below the median demonstrate a 530 percent increase in the number of monthly movie ratings while those above the median decrease their ratings by 62 percent when given outcome information about the average user s net benefit score above average users mainly engage in activities that help others our findings suggest that effective personalized social information can increase the level of public goods provision

how economic contractions and expansions affect expenditure patterns in this study we attempt to understand how household budget allocations across various expenditure categories change when the economy is in recession or expansion the common assumption is that a household s tastes would not change as a function of economic conditions and therefore any adjustments in expenditure patterns during economic contractions expansions would simply be due to changes in the consumption budget standard economic models translate these budgetary effects into lateral movements along a set of fixed engel curves which relate category expenditure shares to total expenditures we propose and test a conceptual framework based on the notion of relative consumption which prescribes that for any given total consumption budget expenditure shares for positional goods services will decrease during a recession while shares for nonpositional goods services will increase i e shifting the entire engel curve upward or downward depending on the nature of the expenditure category and the economic conditions

winners and losers among a refugee hosting population abstractthe impact of a sudden mass influx of forced migrants on the hosting economy is understudied and not well understood using a household panel data set for the kagera region in tanzania we test the impact of the mass refugee presence on the welfare of the local population our identification strategy exploits variations in the timing of arrival as well as the spatial distribution of rwandese and burundi refugees we find a positive and aggregate effect but households are affected differently depending on their main initial occupation

are positional concerns stronger in some domains than in others for more than one hundred years economists have discussed the concept of positional goods that the utility conferred by many perhaps even most goods depends not only on the amount the individual consumes but also on the amount others consume e g thorstein veblen 1899 james duesenberry 1949 john k galbraith 1958 robert frank 1985 while economic interest in positional goods is increasing e g mark pingle and mike mitchell 2002 kenneth arrow et al 2004 ed hopkins and tatiana kornienko 2004 the literature remains largely theoretical rather than empirical if status concerns affect all items in the utility function equally leisure as well as goods the positional effect would operate like a lump sum tax reducing well being without changing the allocation of time or money arrow et al 2004 however if positional concerns are stronger for some things than for others then in order to understand how people can become better off in well being not simply in wealth we must investigate how interpersonal competition interacts with material gains frank 1997 evidence about what goods are more positional than others is essential for correct policy recommendations gregory besharov 2002 but little is actually known about the relative positional rankings of items in the typical consumer s utility function four hypotheses proposed in the literature are

optimal income tax in the presence of status effects abstract the existence of distortions from individuals competing to attain social status by using consumption signals justifies some measure of income tax as a counter acting distortion the question posed here is whether it also constitutes a reason for a more progressive income tax schedule the answer is found to be broadly negative if progressiveness is interpreted as a more convex tax schedule unless the rich are more concerned with status seeking than the poor on the other hand status seeking makes the optimal tax schedule steeper so that redistribution is increased essentially the analysis of status seeking based on a signaling approach confirms and strengthens the existing view of an optimal tax schedule and can be incorporated into the diamond american economic review 88 1998 83 95 approach

a test of conspicuous consumption visibility and income elasticities abstract this paper shows that consistent with a signaling by consuming model a la veblen income elasticities can be predicted from the visibility of consumer expenditures we outline a stylized conspicuous consumption model where income elasticity is endogenously predicted to be higher if a good is visible and lower if it is not we then develop a survey based measure of expenditure visibility ranking different expenditures by how noticeable they are to others finally we show that our visibility measure predicts up to one third of the observed variation in elasticities across consumption categories in u s data

the governance of sustainable socio technical transitions a quasi evolutionary model of socio technical transitions is described in which regimes face selection pressures continuously differentiated transition contexts determine the form and direction of regime change in response to these pressures the articulation of pressures and the degree to which responses are coordinated and based on resources available within the regime define the transition context four alternative contexts are described endogenous renewal re orientation of trajectories emergent transformation and purposive transitions agency and power in the governance of regime transformation are analysed power to affect change depends on regime membership the distribution of resources for change and expectations

household consumption smoothing through ethnic ties evidence from cote d ivoire abstract this paper investigates the hypothesis that households in cote d ivoire take part in spatially diversified risk sharing arrangements with members of their own ethnic group empirical tests are presented using several estimation methods to deal with heteroscedasticity measurement error and extreme value problems to examine whether results are robust across estimation procedures the hypothesis of complete risk sharing within ethnic groups is rejected however there appears to be some partial insurance performed by individual households with other members of the same ethnic group particularly for the households residing in the regions least likely to have access to formal financial arrangements

the social contingency of wants abstract economic models typically assume that individual wants are determined by forces exogenous to the economic system social psychology and consumer research in contrast support the view that the perceived benefits of goods and services are strongly affected by endogenously determined social norms we present a selective overview of the literature on the relationship between consumption and well being exploring the ways in which informal arguments from social science might be linked to formal models of economic behavior we find that the fixed preferences hypothesis leads to the systematic undervaluation of environmental services and the underprovisioning of environmental goods

extended families and child well being studies of household behavior have established the distribution of resources among household members predicts spending and savings patterns however there is a paucity of evidence on the relationship between the well being of individual family members and the distribution of resources within an extended family including non co resident family members given the central role the family plays in many models of economic behavior this is an important gap in the literature using rich longitudinal survey data from the indonesia family life survey ifls evidence is presented on the relationship between three measures of health and education related human capital of children and the distribution of resources among extended family members ifls is ideally suited for this research since the survey collects detailed information about income and wealth from both coresident and non co resident family members the empirical model is founded on a natural extension of the collective model of household decision making chiappori 1988 1992 to the extended family the model is particularly appealing in this context because it places few restrictions on preferences of individual family members and does not specify a specific bargaining mechanism that underlies negotiations the collective model yields empirical tests of whether the behavior of family members is pareto efficient a special case of the model allows all family members to be completely altruistic which is observationally equivalent to a unitary model of family behavior that special case is rejected by the data however the restrictions of the efficient model are not rejected indicating that non co resident family members are able to co ordinate allocation decisions with respect to child human capital investments in such a way as to make no family member better off without another member being worse off

group size and the efficiency of informal risk sharing this paper seeks to understand and test empirically the relationship between group size and informal risk sharing models of informal risk sharing with limited commitment and grim trigger punishments upon deviation imply that larger groups provide better insurance however when subgroups of households can credibly deviate so that sustainable informal arrangements ought to be coalition proof the relationship between group size and the amount of insurance is unclear building on genicot and ray 2003 we show that this relationship is theoretically ambiguous we then investigate it empirically using data on the size of the sibships of the household head and spouse in rural malawi to identify the relevant potential risk sharing group we exploit a social norm among the main ethnic group in our sample that the wife s brothers play a key role in ensuring her household s wellbeing we find that households where the wife has many brothers are poorly insured against crop loss events we fail to uncover a similar relationship for the wife s sisters ruling out that our findings are driven by wives with many siblings e g brothers simply having poorer extended family networks a simple calibration exercise indicates that the threat of coalitional deviations can explain our empirical findings

intermediaries and innovation support in the design for sustainability field cases from the netherlands turkey and the united kingdom abstract companies face challenges and need support when applying specific knowledge to their innovation processes such as design for sustainability the providers of innovation support in innovation systems are intermediaries while the literature on intermediaries focuses on various roles and approaches the way in which intermediaries function in specific fields such as design for sustainability remains underexplored this paper investigates how intermediaries provide innovation support in the design for sustainability field today with a focus on the services and support they offer the approaches and drivers that shape them as well as the challenges of the intermediation process particularly concerning sustainability and design to do this 14 intermediaries from the netherlands the united kingdom and turkey were investigated through case studies the role of design in support processes especially during implementation the importance and types of collaborations among various actors of innovation systems and the emergence of a new type of intermediary that promises radical innovation in sustainability are among the findings in addition based on the empirical data we suggest a framework for describing the roles and attributes of a group of five intermediaries that meets the needs of all types of companies engaged in design for sustainability finally we offer suggestions for turkey on how to raise the capacity of its intermediaries operating in the design for sustainability field which might be applicable to other similar contexts as well this study contributes to the theory and practice of innovation support in the sustainability field from which all innovation system s actors especially intermediaries and governmental institutions might benefit in designing support programs

adult mortality and consumption growth in the age of hiv aids the authors use a 13 year panel of individuals in tanzania to assess how adult mortality shocks affect both short and long run consumption growth of surviving household members using unique data which tracks individuals from 1991 to 2004 they examine consumption growth controlling for a set of initial community household and individual characteristics the effect is identified using the sample of households in 2004 which grew out of baseline households the authors find robust evidence that an affected household will see consumption drop 7 percent within the first five years after the adult death with high growth in the sample over this time period this creates a 19 percentage point growth gap with the average household there is some evidence of persistent effects of these shocks for up to 13 years but these effects are imprecisely estimated and not significantly different from zero the impact of female adult death is found to be particularly severe

conspicuous consumption and race evidence from south africa abstract a century ago thorstein veblen introduced socially contingent consumption into the economic literature this paper complements the scarce empirical literature by testing his conjecture on south african household data and finds that black and coloured households spend relatively more on visible consumption than comparable white households following the approach of charles et al 2009 this paper explores whether the differences in visible expenditures can be explained with a signaling model of status seeking moreover it is assessed to which extent positional concerns motivate conspicuous consumption although the socially contingent share in visible consumption increases with income different incentives to consume conspicuously seem to explain that at every level of income black households spend relatively more on visible consumption than comparable white households in contrast to the findings of charles et al 2009 where differential spending on conspicuous consumption can be found also within each group separately the model s core hypothesis fails to hold within the group of white south africans

global income distributions and inequality 1993 and 2000 incorporating country level inequality modeled with beta distributions abstract using a method of moments estimator flexible three parameter beta distributions are fitted to aggregate country level income data to overcome an untenable assumption of previous studies that persons within each income group receive the same income regional and global income distributions are derived as weighted mixtures of country specific distributions analytical expressions for gini and theil s measures of inequality at country regional and global levels are derived in terms of the parameters of the beta distributions application to data for 91 countries in 1993 and 2000 reveals a high degree of global inequality with evidence of declining inequality largely attributable to growth in china

income smoothing and consumption smoothing one way that risk averse households protect consumption levels is to borrow and use insurance mechanisms another way common in low income economies is to diversify economic activities and make conservative production and employment choices households thus tend toward limiting exposure only to shocks that can be handled with available credit and insurance typically both types of mechanisms are studied independently but much more can be learned by studying them together first we obtain a more complete picture of risks costs and insurance possibilities second it opens the way to considering biases in standard tests of credit and insurance

testing efficient risk sharing with heterogeneous risk preferences previous papers have tested e cient risk sharing under the assumption of identical risk preferences in this paper we show that if in the data households have heterogeneous risk preferences the tests proposed in the past reject e ciency even if households share risk e ciently to address this issue we propose a method that enables one to test e ciency even when households have difierent preferences for risk the method is composed of three tests the flrst one can be used to determine whether in the data under investigation households have homogeneous risk preferences the second and third test can be used to evaluate e cient risk sharing when the hypothesis of homogeneous risk preferences is rejected we use this method to test e cient risk sharing in rural india using the flrst test we strongly reject the hypothesis of identical risk preferences we then test e ciency with and without the assumption of preference homogeneity in the flrst case we reject e cient risk sharing at the village and caste level in the second case we still reject e ciency at the village level but we cannot reject this hypothesis at the caste level this flnding suggests that the relevant risk sharing unit in rural india is the caste and not the village

conspicuous consumption and race using nationally representative data on consumption we show that blacks and hispanics devote larger shares of their expenditure bundles to visible goods clothing jewelry and cars than do comparable whites these differences exist among virtually all subpopulations are relatively constant over time and are economically large although racial differences in utility preference parameters might account for a portion of these consumption differences we emphasize instead a model of status seeking in which conspicuous consumption is used as a costly indicator of a household s economic position using merged data on race and state level income we demonstrate that a key prediction of the status signaling model that visible consumption should be declining in reference group income is strongly borne out in the data for each racial group moreover we show that accounting for differences in reference group income characteristics explains most of the racial difference in visible consumption

risk sharing between and within families this paper uses the panel study of income dynamics to test whether risk sharing is complete between or within american families the tests accommodate a wide variety in the configuration and availability of family data the test results reject inter as well as intra family full risk sharing even assuming that leisure is endogenous or that leisure and consumption are nonseparable

novelty preferences and fashion when goods are unsettling abstract there is a whole class of goods those semi durable and durable conveniences for which efficiency and functionality seem not to be the main characteristics of appeal but rather the variability they display in their design properties and in their connections with other goods these goods have not been much dealt with in economics yet these are the goods whose new variants households seem to consume in numbers to which consumers become addicted and in which fashions appear and disappear in this paper i offer a framework for understanding these phenomena without having to resort to one or another form of irrationality on the part of consumers the rationality i suggest however has to include also the cognitive and affective problems that arise when novelty appears

running to keep in the same place consumer choice as a game of status if individuals care about their status defined as their rank in the distribution of consumption of one positional good then the consumer s problem is strategic as her utility depends on the consumption choices of others in the symmetric nash equilibrium each individual spends an inefficiently high amount on the status good using techniques from auction theory we analyze the effects of exogenous changes in the distribution of income in a richer society almost all individuals spend more on conspicuous consumption and individual utility is lower at each income level in a more equal society the poor are worse off

the role of policy in shielding nurturing and enabling offshore wind in the netherlands 1973 2013 it is widely acknowledged that many renewable energy technologies cannot yet compete with incumbent fossil fuel options e g in terms of price transitions literature argues that sustainable innovations can nevertheless break out of their niches if properly shielded nurtured and empowered most studies using this perspective have focused on how innovation champions engage in shielding nurturing and empowering sne activities none have so far focused specifically on the role that policy plays in relation to these three processes this paper therefore aims to analyze the way in which policy constrains and enables the shielding nurturing and empowering of renewable energy innovations to do so it presents a qualitative review of the development of offshore wind power owp in the netherlands over the past four decades based on interpretation of a wide variety of written sources academic histories reports policy documents parliamentary debate transcripts news media and nine semi structured interviews it discerns six periods of relative stability in the history of dutch offshore wind it then analyzes the effects of various policies on the shielding nurturing and empowering of offshore wind in these periods the paper contributes to transitions literature 1 by providing an analysis of how policies can enable and constrain the shielding nurturing and empowering of renewable energy innovations and 2 by bringing together for the first time fragmented accounts of the surprisingly long history of dutch offshore wind development and implementation both contributions are timely given the recent reprioritization of owp on the dutch policy agenda

innovation intermediaries accelerating environmental sustainability transitions abstract institutions in the united states are undergoing modifications that present direct challenges for the environment and society and may result in institutional uncertainty and instability this article explores whether innovation intermediaries can be employed as a key component of a strategy to create a window of opportunity for green job creation infrastructure changes and technological innovation in response to these types of institutional modifications based on a systematic literature review this article outlines a framework that combines institutional modifications with technological innovation and infrastructure development as part of an economic development strategy important findings are that connections between innovation intermediaries such as incubator and accelerator centers niche actors such as green champions and regime actors such as policy entrepreneurs show potential to contribute to a green economic development strategy but require further examination for the specific roles played by policy entrepreneurs to help create the conditions for scaling niche experiments and simultaneously disrupting the regime the key contribution is in defining the role of sustainability oriented innovation intermediaries at linking local state and business actions in order to scale up and influence green economic development in a politically feasible manner during times of institutional uncertainty and instability

is consumption insured against illness evidence on vulnerability of households to health shocks in rural ethiopia abstract low and volatile incomes and absence of well developed financial markets make consumption smoothing an important issue in low income countries based on the theory of full insurance and using 2 years of panel data this study examines the impact of illness on the consumption of rural households and the capacity of existing risk sharing mechanisms in insuring consumption against health shocks in the rural areas of ethiopia the results show that illness has a statistically significant negative impact on the stability of consumption and the capacity of households or existing intra and interhousehold risk sharing arrangements in insuring consumption against illness varies across different consumption items the regression results show that the hypothesis of consumption insurance cannot be rejected in the case of total food consumption implying that basic items that come from own production and from external sources gifts are better insured and insensitive to the illness of the head however the

risk and insurance in village india comment the protection of poor households in high risk agrarian economies from shocks to their incomes has often been seen as a compelling motive for various forms of policy intervention including transfers of cash or food credit subsidies and public employment schemes for a survey see lipton and ravallion 1995 the desirability of such safety net policies clearly depends on how well pre existing risk sharing arrangements work while it is commonly thought that without effective policy intervention rural households are vulnerable to village wide shocks such as adverse prices or poor rains it is less clear to what extent risk sharing institutions within the village mitigate the effects of idiosyncratic income risk stemming for instance from ill health or localized crop damage 2 several recent papers have used household level data to implement tests of risk sharing that might inform such concerns 3 these tests are based on the proposition that with perfect risk sharing consumption at the household level should be insured against idiosyncratic risks and thus depend solely on the realization of the aggregate risk wilson 1968 diamond 1967 townsend 1994 tests this implication of perfect intra village risk sharing using longitudinal household data on consumptions and incomes for three villages in india he reports that the full insurance hypothesis provides a surprisingly good benchmark in that household consumptions co move and do not appear to be much influenced by contemporaneous own income our aim here is to examine the robustness of this potentially important finding we have two main concerns the first is that the specification townsend adopts potentially biases his test towards the null hypothesis of full insurance because it yields inconsistent estimates of the key test parameter under a plausible alternative we therefore estimate a different specification that generates consistent estimates under both the null and the alternative our second concern is that a particular form of measurement error in the consumption data townsend uses may have further biased his results toward the null hypothesis of full insurance to address this concern we use an instrumental variables procedure when we implement the test of consumption insurance with townsend s consumption data we also re estimate the test equations with a measure of consumption derived from the same underlying primary data by an alternate method finally townsend reports 1discussions with robert townsend stimulated our interest in this investigation the staff of the

positional deprivation and support for radical right and radical left parties we explore how support for radical parties of both the left and right may be shaped by what we call positional deprivation where growth in income of individuals at a given point in the income distribution is outpaced by income growth elsewhere in that distribution we argue that positional deprivation captures the combination of over time and relative misfortune that can be expected to distinctly spur support for radical left and right parties we explore this possibility by matching new measures of positional deprivation to individual level survey data on party preferences in 20 european countries from 2002 to 2014 we find that positional deprivation is robustly correlated with supporting radical populist parties first positional deprivation generally measured as average income growth across deciles of a country s income distribution minus a respondent s own decile s growth is associated with respondents retreat from mainstream parties and with support for both radical right and particularly radical left parties second positional deprivation relative to the highest and the lowest ends of the income spectrum play out differently for radical right and for radical left support a respondent s positional deprivation relative to the wealthiest decile s growth in his or her country tends to spur support for radical left but not radical right parties in contrast positional deprivation relative to the poorest decile s growth in a respondent s country tends to spur support for radical right but not left parties the results suggest that the combination of over time and relative economic misfortune may be key to how economic experience shapes radical backlash of the left and right

the effect of unionism on fringe benefits this study analyzes the impact of unionism on fringes paid to production workers using data on individual establishments it compares fringe expenditures in establishments having the same level of compensation per hour and finds that unionism raises the share of compensation allotted to fringes particularly to pensions vacation pay and life accident and health insurance in addition since unionism also raises the straight time wage rate itself a prime determinant of expenditures on fringes unionism has a very sizeable impact on total fringe expenditures as well as on the fringe share of compensation the union fringe effect exceeds in percentage terms the union wage effect and is sufficiently large to suggest that standard union wage studies understate the union effect on total compensation the study also compares the fringe expenditures of production and non production workers within the same establishment controlling for within establishment pay policies the findings suggest that the pres

social norms savings behavior and growth we argue that many goods and decisions are not allocated or made through markets we interpret an agent s status as a ranking device that determines how well he or she fares in the nonmarket sector the existence of a nonmarket sector can endogenously generate a concern for relative position in for example the income distribution so that higher income implies higher status moreover it can naturally yield multiple equilibria it is thus possible to explain differences in growth rates across countries without recourse to differences in underlying preferences technologies or endowments different social organizations lead to different reduced form preferences which lead to different growth rates

risk sharing within the extended family evidence from the indonesia family life survey abstractin recent years there has been an increase in the availability of longitudinal household surveys in developing countries that allow the researchers to construct linkages between households with familial ties this type of data allows researchers to look at whether some household outcomes are influenced by decisions made at the extended family level this article utilizes data from two waves of the indonesia family life survey 1997 and 2000 to construct a panel of extended families in order to focus on one particular example of such outcome whether consumption risk sharing occurs among households within the extended family the findings show that after controlling for the extended family fixed effects changes in the household s own income still matter for changes in its consumption rejecting full consumption risk insurance however the coefficients on household own income are small indicating significant degrees of risk sharing results from a set of reduced form estimations suggest that ho

the equilibrium distribution of income and the market for status this paper explores the implications for risk taking behavior and the equilibrium distribution of income of assuming that the desire for status positions is a powerful motive and that it raises the marginal utility of consumption in contrast to previous analyses we consider the case in which status positions are sold in a hedonic market we show that such a complete hedonic market in status positions can be perfectly replicated by a simpler arrangement with a status good and a social norm that assigns higher status to those that consume more of this good the main result is that for a wide range of initial conditions the equilibrium distribution over income status and consumption is the same that this allocation requires inequality of income and consumption and that this allocation coincides with the optimum of a utilitarian planner

full insurance in the presence of aggregate uncertainty this paper tests implications of full consumption insurance the object is to determine how much mileage can be obtained from a model with complete markets with such features as private information or liquidity constraints omitted the implication exploited is that individual consumption responds to aggregate risk but not to idiosyncratic risk the test involves regressing the change in household consumption onto the change in aggregate consumption and other right hand side variables such as the change in household income and change in employment status all variables other than the change in aggregate consumption are predicted to be insignificant in explaining the change in household consumption with observations on consumption and income for 10 695 households from the consumer expenditure survey the results are mixed the results for one specification exponential utility are mostly consistent with full consumption insurance the results for the other specification power utility are not

dynamic asset allocation with relative wealth concerns in incomplete markets abstract in dynamic portfolio choice problems stochastic state variables such as stochastic volatility lead to adjustments of the optimal stock demand referred to as hedge terms or merton breeden terms by deriving an explicit solution in a two agent framework with a stochastic opportunity set we show that relative wealth concerns give rise to new hedge terms beyond the ordinary ones this is because the agents hedge against both exogenous changes in the state variable and endogenous decisions of the other agent depending on the parametrization of the model these new terms can significantly change the investors hedging demands we also show that both heterogeneity in risk aversion or relative wealth concerns can have similar effects on the heterogeneity in portfolio decisions formally we study a non cooperative non zero sum stochastic differential game for which we prove a verification theorem in a setting with an unspanned state variable

relative consumption and tax evasion abstract relative consumption effects or status concerns that feature jealousy in the sense of dupor and liu 2003 boost consumption expenditure if consumption is financed by labour income such status considerations increase labour supply and hence the tax base a higher taxable income in turn can make tax evasion more attractive we show for various specifications of preferences that the tax base effect generally dominates consequently relative consumption effects tend to reduce tax evasion this is true irrespective of whether tax parameters are exogenous guarantee a balanced budget or are set optimally

government affiliated intermediary organisations as actors in system level transitions the article draws from two theoretical fields innovation intermediation and sustainability transitions to examine the role of government affiliated intermediary organisations in system level transitions the role of intermediaries working between actors producers and users entrepreneurs and adopters idea generators and funders has seldom been specifically addressed in the transitions literature thus the role of intermediary organisations in enacting change in socio technical regimes particularly of intermediaries falling between traditional public sector and private sector actors is of interest in this article empirical analyses of two finnish organisations sitra and motiva show that government affiliated intermediaries are likely to engage in strategic niche management processes in diverse ways each organisation having its own distinct characteristics the analysis also points out that to get from niches to transition sustained systemic intermediaries are crucial in articulating new visions and expectations government affiliated intermediaries may make an important contribution to sustainability transitions by initiating and managing new policy or market processes and by acting as an impartial contact point or voice for new networks of actors while independence from public administration is likely to facilitate networking too neutral a stance or limited temporal engagement may reduce the transition facilitating effects

centralisation and decentralisation in strategic municipal energy planning in denmark denmark s future energy system is to be entirely based on renewable energy sources municipalities will play an important role as local energy planning authorities in terms of adopting and refining this vision in different local contexts based on a review of 11 municipal energy plans this paper examines to what extent municipal energy planning matches national 100 renewable energy strategies the results indicate a willingness among danish municipalities to actively carry out energy planning and the plans reveal a large diversity of new activities at the same time however there is a strong need for better coordination of municipal energy planning activities at the central level it is suggested that the role of municipalities as energy planning authorities needs to be outlined more clearly in e g strategic energy planning which integrates savings efficiency and renewable energy in all energy sectors this requires the state to provide municipalities with the necessary planning instruments and establish a corresponding planning framework consequently there is a need for a simultaneous centralisation and decentralisation during the implementation of the 100 renewable energy vision the paper outlines a basic division of tasks between the central and the local level within such a strategic energy planning system

a simple test of consumption insurance are consumers effectively insured against idiosyncratic shocks to income or wealth either by formal institutions such as charities private insurance and government programs or by informal mechanisms such as gifts and loans from relatives friends and neighbors under full insurance consumption growth should be cross sectionally independent of idiosyncratic variables that are exogenous to consumers this proposition is tested by cross sectional regressions of consumption growth on a variety of exogenous variables full insurance is rejected for long illness and involuntary job loss but not for spells of unemployment loss of work due to strike and an involuntary move

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

realising local government visions for developing district heating experiences from a learning country abstract district heating dh has an important role to play in enabling cities to transition to low carbon heating although schemes are commonplace in some countries in learning countries where building level technologies make up the majority of heating systems there are numerous barriers to introducing dh local governments are seen as key actors in helping to create a shared vision for dh amongst stakeholders this study uses interviews with stakeholders from a range of sectors in the uk an example of a learning country to examine the visions of local actors for developing dh and the types of national policy that would support local implementation of these visions the analysis shows that in engaging with dh development local governments seek multiple types of value realising this value will most likely happen by taking a long term planned approach to development in contrast national government policy is geared towards techno economic criteria and may lead to only a minority of potential sites being developed without realisation of wider social or environmental benefits aligned to local visions the work highlights the importance of local strategic planning enabled by aligned national policy in realising the full economic environmental and social benefits of dh

conspicuous spending and the income distribution of social groups using south african household expenditure data we analyze how the spending of a household on visible goods such as jewelry and clothes depends on the distribution of income within its social group we find that this spending is positively correlated with the share of peers who possess a similar income level to the household what we dub the local income share moreover we find that the spending of a household on visible goods is positively correlated with the average income of peers that are poorer than this household we interpret this as evidence for cascade effects through which income changes among the poorest in the social group can trigger adjustments in the visible spending patterns of the wealthy in line with previous research charles et al 2009 we also find that visible spending of a household is negatively correlated with the average income of its social group we present a simple model of status competition based on hopkins and kornienko 2004 that synthesizes these effects and can account for our results jel d12 d31 o12

parental altruism and inter vivos transfers theory and evidence this paper uses psid data on the extended family to test whether inter vivos transfers from parents to children are motivated by altruism specifically the paper tests whether an increase by one dollar in the income of parents actively making transfers to a child coupled with a one dollar reduction in that child s income results in the parents increasing their transfer to the child by one dollar this restriction on parental and child transfer income derivatives is derived for the standard altruism model augmented to include uncertainty and liquidity constraints these additional elements pin down the timing of inter vivos transfers the method used to estimate income transfer derivatives takes into account unobserved heterogeneity across families in the degree of altruism the findings strongly reject the altruism hypothesis redistributing one dollar from a recipient child to donor parents leads to less than a 13 cent increase in the parents transfer to the child far less than the one dollar increas

education in a crisis abstract the year 1998 saw the onset of a major economic and financial crisis in indonesia gdp fell by 12 that year the effect on education of the next generation is examined on average household spending on education declined most dramatically among the poorest households spending reductions were particularly marked in poor households with more young children while there was a tendency to protect education spending in poor households with more older children the evidence on school enrollments mirrors these findings poor households apparently sought to protect investments in the schooling of older children at the expense of the education of younger children

the intermediary organisation of low carbon cities a comparative analysis of transitions in greater london and greater manchester making a low carbon economic future for the uk has been declared a key priority by both the previous labour government and also the current coalition government yet there is a large gap between th

conspicuous consumption snobbism and conformism abstract we develop a model in which consumers purchase a conspicuous good in order to signal high income and thereby achieve greater social status in equilibrium the signalling value of conspicuous consumption depends in an identifiable way on the number of consumers and consumer behaviour is characterized by either snobbism or conformism the market demand curve for the conspicuous good may exhibit a positive slope if consumers are conformist we derive some unconventional policy implications concerning the taxation of luxuries and the voluntary provision of public goods

positional spending and status seeking in rural china focusing on a remote area in rural china we use a panel census of households in 26 villages to show that socially observable spending has risen sharply in recent years we demonstrate that such spending by households is highly sensitive to social spending by other villagers this suggests that social spending is either positional in nature i e motivated by status concerns or subject to herding behavior we also document systematic relations between social spending and changes in higher order terms of the income distribution we find that the implications of status seeking for spending are not unidimensional they vary across income groups and expenditure categories in particular and consistent with theories of rank based status seeking we find that the poor increase spending on funerals and gifts as competition for status intensifies in addition poor families of grooms expend more for wedding ceremonies as local income competition increases while the families of brides do not the welfare implications of spending in order to keep up with the joneses are potentially large particularly for poor households

status the distribution of wealth private and social attitudes to risk this paper supposes an individual cares about his her own wealth not only directly but also via the relative standing that this wealth induces the implications for risk taking are investigated in particular such a model provides a natural explanation of the concave convex concave utility described by friedman and savage however there are a number of key differences between the present model and any model based on own wealth alone for example an equilibrium wealth distribution here may have a middle class further the status interaction involves an externality and an equilibrium wealth distribution may be pareto inefficient but also about the implied relative standing in the distribution of wealth has a long but checkered history an early exponent of such ideas was of course veblen 1899 it is indeed a notion which most economists reject albeit usually without explicit comment a notable and articulate exception however is frank 1985 for example see also the references frank cites on pp 33 34 it is however a notion with substantial intuitive appeal and it seems useful to ascertain its consequences before coming to a final judgement as to its merits the present paper is concerned with deriving the consequences of such valuation of status for risk taking what seems to be the sharpest possible model is adopted here this assumes that what is essentially ordinal rank in the wealth distribution enters von neumann morgenstern utility as an argument in addi tion to wealth itself thus higher wealth increases utility not only directly but also indirectly via higher status in the interests of both simplicity and drama it is typically assumed here that all individuals have identical utility functions which are concave in wealth but convex in status section 2 discusses how the model provides a natural explanation of the fundamental phenomenon addressed by friedman and savage 1948 that individuals may simultaneously purchase insurance and participate in lotteries although each individual here has a utility function which is concave in wealth itself utility can nevertheless be convex in wealth over some range when the indirect effect via status is included this effect is enhanced by the convexity of utility in status but will follow in any case if increasing wealth entails moving up in status much more rapidly than losing wealth entails moving down it is shown

social comparisons status and driving behavior abstract the establishment of desirable social norms is an integral part of a well functioning civil society while recent evidence has demonstrated that social comparison can affect behavior in a variety of contexts it is not clear what type of comparative social information is most effective using a large scale field experiment to study driving practices we sent text messages containing different types of social information to drivers in tsingtao china we find two types of social information to be particularly effective in reducing traffic violations the driving behavior of those similar to oneself and the driving behavior of those with high status cars our results indicate that the combination of descriptive norms with social status is a cost effective yet powerful intervention for establishing better driving behavior in emerging markets

getting ahead of the joneses when equality increases conspicuous consumption among bottom tier consumers it is widely believed that increasing the equality of material possessions or income in a social group should lead people at the bottom of the distribution to consume less and save more however this prediction and its causal mechanism have never been studied experimentally five studies show that greater equality increases the satisfaction of those in the lowest tier of the distribution because it reduces the possession gap between what they have and what others have however greater equality also increases the position gains derived from status enhancing consumption since it allows low tier consumers to get ahead of the higher proportion of consumers clustered in the middle tiers as a result greater equality reduces consumption when consumers focus on the narrower possession gap but it increases consumption when they focus on the greater position gains i e when consumption is conspicuous social competition goals are primed and the environment is competitive

consumption smoothing migration and marriage evidence from rural india a significant proportion of migration in low income countries particularly in rural areas is composed of moves by women for the purpose of marriage we seek to explain these mobility patterns by examining marital arrangements among indian households in particular we hypothesize that the marriage of daughters to locationally distant dispersed yet kinship related households is a manifestation of implicit interhousehold contractual arrangements aimed at mitigating income risks and facilitating consumption smoothing in an environment characterized by information costs and spatially covariant risks analysis of longitudinal south indian village data lends support to the hypothesis marriage cum migration contributes significantly to a reduction in the variability of household food consumption farm households afflicted with more variable profits tend to engage in longer distance marriage cum migration the hypothesized and observed marriage cum migration patterns are in dissonance with standard models of marriage or migration that are concerned primarily with search costs and static income gains
