strategies for promoting healthier food choices between 1960 and 2004 the proportion of americans meeting standard criteria for obesity increased from 13 percent to 31 percent katherine m flegal et al 2002 and it has been proposed that if this trend is not reversed obesity may soon overtake smoking as the leading preventable cause of death ali h mokdad et al 2004 consequently obesity is now one of the major causes of rising health care costs eric a finkelstein christopher j ruhm and katherine m kosa 2005 empirical analyses suggest that an increase in caloric intake rather than a change in calorie expenditure is responsible for much of the trend david m cutler edward l glaeser and jesse m shapiro 2003 the main policy response to what is often referred to as the obesity epidemic has been to enhance access to information the most prominent example of such a policy is the nutrition labeling and education act united states food and drug administration 1994 but recently the tactic has been receiving more attention after new york city required restaurants with 15 or more outlets to post the caloric content of each food item next to its price on menu boards lawmakers and independent companies alike are now following new york city s lead kim severson 2008 however there is little evidence that information alone does much to improve diet jayachandran n variyam and aq 1 the psychology of food consumption

an economy of scales a selective review of obesity s economic causes consequences and solutions this paper reviews the economic research on obesity covering topics such as the measurement of and trends in obesity the economic causes of obesity e g the monetary price and time cost of food food assistance programs income education macroeconomic conditions and peer effects and the economic consequences of obesity e g lower wages a lower probability of employment and higher medical care costs it also examines the extent to which obesity imposes negative externalities and economic interventions that could potentially internalize such externalities such as food taxes subsidies for school based physical activity programs and financial rewards for weight loss it discusses other economic rationales for government intervention with respect to obesity such as imperfect information time inconsistent preferences and irrational behavior it concludes by proposing a research agenda for the field overall the evidence suggests that there is no single dominant economic cause of obesity a wide variety of factors may contribute a modest amount to the risk there is consistent evidence regarding the economic consequences of obesity which are lower wages and higher medical care costs that impose negative externalities through health insurance studies of economic approaches to preventing obesity such as menu labeling taxes on energy dense foods and financial rewards for weight loss find only modest effects on weight and thus a range of policies may be necessary to have a substantial effect on the prevalence of obesity

time use and food consumption people are getting fat the rise in obesity rate has been particularly pronounced in the united states since the middle of the 1970s but has by now extended into many other areas of the world several sources of technological change have been singled out as potential explanations for why people have been gaining so much weight increased productivity in agriculture has lowered the relative price of food darius lakdwalla tomas philipson and jayanta bhattacharya 2005 while innovations in food processing have reduced the time cost of preparing food david m cutler edward l glaeser and jesse m shapiro 2003 technological change has also affected how people spend their time in a way that may systematically have reduced calories expended first physically less demanding jobs in the service sector have replaced physically more demanding jobs in agriculture and manu facturing second the allocation of time across different activities has changed dramatically over the last few decades people are spending less time working decline in labor market work for men decline in home production work for women and more time in mainly sedentary forms of leisure such as watching tv mark aguiar and erik hurst 2007 while the focus so far has been on the rela tionship between how people spend their time and how many calories they expend we argue in this piece that there might also be an inter esting relationship between how people spend their time and how many calories they consume motivating this question is a at first glance rather counterintuitive finding from the time use surveys the fact that people in the united states

tax multipliers pitfalls in measurement and identification abstract to analyze the pitfalls in measuring and identifying tax shocks we build a novel value added tax rate dataset for the period 1980 2009 the problem of identification i e changes in tax policy not triggered by output fluctuations is clearly disentangled from the problem of measurement i e finding a tax policy variable under the direct control of policymakers on the identification front our results favor the use of narratives a la romer and romer 2010 on the measurement front our findings support the use of tax rates as the true measure of tax policy as opposed to revenue based measures such as cyclically adjusted revenues

revisiting the sen poverty index a modification of the official sen poverty index yields an index which is not only continous in individual incomes and consistent with the transfer axiom but also admits a geometric interpretation in terms of the area beneath a graph called the inverse generalized lorenz curve for normalized poverty gaps by jenkins and lambert 1993 or the poverty gap profile by shorrocks 1994

prioritarian poverty comparisons with cardinal and ordinal attributes the ethical view of prioritarianism holds the following if an extra bundle of attributes is to be allocated to either of two individuals then priority should be given to the worse off among the two we consider multidimensional poverty comparisons with cardinal and ordinal attributes and propose three axioms that operationalize the prioritarian view each priority axiom in combination with a handful of standard properties characterizes a class of poverty measures this article is protected by copyright all rights reserved

counting and multidimensional poverty measurement this paper proposes a new methodology for multidimensional poverty measurement consisting of an identification method k that extends the traditional intersection and union approaches and a class of poverty measures m our identification step employs two forms of cutoff one within each dimension to determine whether a person is deprived in that dimension and a second across dimensions that identifies the poor by counting the dimensions in which a person is deprived the aggregation step employs the fgt measures appropriately adjusted to account for multidimensionality the axioms are presented as joint restrictions on identification and the measures and the methodology satisfies a range of desirable properties including decomposability the identification method is particularly well suited for use with ordinal data as is the first of our measures the adjusted headcount ratio we present some dominance results and an interpretation of the adjusted headcount ratio as a measure of unfreedom examples from the us and indonesia illustrate our methodology

short run needs and long term goals a dynamic model of thirst management beverage consumption occurs many times a day in response to short run needs that fluctuate we develop a model in which consumers are heterogeneous in self regulating consumption by balancing short run needs e g hydration and mood with long term goals e g health the model has two novel features 1 utility depends on the match between occasion specific needs and product attributes and 2 dynamics of consumption and stockpiling are at the level of product attributes we estimate the model using unique intraday beverage consumption activity and psychological needs data we find that only a third of individuals do not self regulate of the two thirds who self regulate over 40 self regulate adaptively based on past choice whereas 25 self regulate both adaptively and anticipating future needs our attribute need match model enables us to assess unmet demand for new products with attributes that match co occurring occasion specific needs specifically we find that a product satisfying a combination of health hydrating needs expands overall beverage consumption by as much as 5 our framework of modeling heterogeneity in self regulation by balancing short run needs with long term goals is more broadly applicable in contexts where situational needs vary and long term effects are gradual and hard to discern e g nutrition smoking and preventive health care

information customization and food choice in this article we employ a hypothetical discrete choice experiment dce to examine how much consumers are willing to pay to use technology to customize their food shopping we conjecture that customized information provision can aid in the composition of a healthier shop our results reveal that consumers are prepared to pay relatively more for individual specific information as opposed to generic nutritional information that is typically provided on food labels in arriving at these results we have examined various model specifications including those that make use of ex post de briefing questions on attribute non attendance and attribute ranking information and those that consider the time taken to complete the survey our main results are robust to the various model specifications we examine

viewpoint beyond carrots and sticks europeans support health nudges abstract all over the world nations are using health nudges to promote healthier food choices and to reduce the health care costs of obesity and non communicable diseases in some circles the relevant reforms are controversial on the basis of nationally representative online surveys we examine whether europeans favour such nudges the simplest answer is that majorities in six european nations denmark france germany hungary italy and the uk do so we find majority approval for a series of nudges including educational messages in movie theaters calorie and warning labels store placement promoting healthier food sweet free supermarket cashiers and meat free days in cafeterias at the same time we find somewhat lower approval rates in hungary and denmark an implication for policymakers is that citizens are highly likely to support health nudges an implication for further research is the importance of identifying the reasons for cross national differences where they exist

inequality measurement for ordered response health data because self reported health status srhs is an ordered response variable inequality measurement for srhs data requires a numerical scale for converting individual responses into a summary statistic the choice of scale is however problematic since small variations in the numerical scale may reverse the ordering of a given pair of distributions of srhs data in relation to conventional inequality indices such as the variance this paper introduces a parametric family of inequality indices founded on an inequality ordering proposed by allison and foster allison r a foster j 2004 measuring health inequalities using qualitative data journal of health economics 23 505 524 which satisfy a suitable invariance property with respect to the choice of numerical scale several key members of the parametric family are also derived and an empirical application using data from the swiss health survey illustrates the proposed methodology

fiscal stabilizations when do they work and why abstract this paper studies the determinants and channels through which fiscal contractions influence the dynamics of the debt to gdp ratio and gdp growth using data from a panel of oecd countries the paper shows that the success of fiscal adjustments in decreasing the debt to gdp ratio depends on the size of the fiscal contraction and less on its composition the rate of growth of output matters too but higher gdp growth does not drive the success of a fiscal stabilization in contrast whether a fiscal adjustment is expansionary depends largely on the composition of the fiscal maneuvre in particular stabilizations implemented by cutting public spending lead to higher gdp growth rates the effects of the composition on growth work mostly through the labor market rather than through agents expectations of future fiscal policy finally the evidence suggests that successful and expansionary fiscal contractions are not the result of accompanying expansionary monetary policy or exchange rate devaluations

aggregate poverty measures the way poverty is measured is important for an understanding of what has happened to poverty as well as for anti poverty policy evaluation sen s 1976 pathfinding work has motivated many researchers to focus on the way poverty should be measured a poverty measure argued by sen should satisfy certain properties or axioms and the desirability of a poverty measure should be evaluated by these axioms during the last two decades many researchers have adopted the axiomatic approach pioneered by sen to propose additional axioms and develop alternative poverty measures the objective of this survey is to provide a clarification on the extensive literature of aggregate poverty measures in this survey we first examine the desirability of each axiom the properties of each poverty measure and the interrelationships among axioms the desirability of an axiom cannot be evaluated in isolation and some combination of axioms may make it impossible to devise a satisfactory poverty measure some axioms can be implied by other axioms combined and so are not independent some others are ad hoc and are disqualified as axioms for poverty measurement based on the interactions among axioms we identify the core axioms which together have a strong implication on the functional form of a poverty measure we then review poverty measures that have appeared in the literature evaluating the interrelationships among different measures and examining the properties of each measure the axioms each measure satisfies violates are also summarized in a tabular form several good poverty measures which have not been documented by previous surveys are also included

mindless eating and healthy heuristics for the irrational food choice decisions are not the same as intake volume decisions the former determine what we eat soup or salad the latter determine how much we eat half of the bowl or all of it large amounts of money time and intelligence have been invested in understanding the physiological mechanisms that influence food choice james o hill forthcoming much less has been invested in understanding how and why our environment influences food consumption volume yet environmental factors such as package size plate shape lighting variety or the presence of others affect our food consumption volume far more than we realize wansink 2006 whereas people can acknowledge that environmental factors influence others they wrongly believe they are unaffected perhaps they are influenced at a basic level of which they are not aware a better understanding of these drivers of consumption volume will have immediate implications for research policy and personal interventions there are three objectives of this paper 1 explain why environmental factors may unknowingly influence food consumption 2 identify resulting myths that may lead to is specified models or misguided policy recommendations and 3 offer clear direction for future research policy and personal dietary efforts

on the measurement of poverty official statistics in the united states and the united kingdom show a rise in poverty between the 1970 s and the 1980 s but scepticism has been expressed with regard to these findings in particular the methods employed in the measurement of poverty have been the subject of criticism this paper re examines three basic issues in measuring poverty the choice of the poverty line the index of poverty and the relation between poverty and inequality one general theme running through the paper is that there is a diversity of judgments which enter the measurement of poverty and that it is necessary to recognize these explicitly in the procedures adopted there is likely to be disagreement about the choice of poverty line affecting both its level and its structure in this situation we may only be able to make comparisons and not to measure differences and the comparisons may lead only to a partial rather than a complete ordering the first section of the paper discusses the stochastic dominance conditions which allow such comparisons illustrating their application by reference to data for the united states the choice of poverty measure has been the subject of an extensive literature and a variety of measures have been proposed in the second section of the paper a different approach is suggested considering a class of measures satisfying certain general properties and seeking conditions under which all members of the class which includes many of those proposed give the same ranking those sceptical about measures of poverty often assert that poverty and inequality are being confounded the third section of the paper distinguishes four different viewpoints and relates them to theories of justice and views of social welfare

assessing deprivation with an ordinal variable theory and application to sanitation deprivation in bangladesh the challenges associated with poverty measurement with a cardinal variable have received due attention during the last four decades but there is a dearth of literature studying how to meaningfully assess poverty with an ordinal variable this paper first proposes a class of simple intuitive and policy relevant poverty measures for ordinal variables these measures are sensitive to depth of deprivations unlike the headcount ratio moreover under appropriate restrictions the measures ensure that priority is given to the poorest among the poor while targeting monitoring and evaluating poverty alleviation programs to assess the robustness of poverty comparisons to alternative choices of parameters various stochastic dominance tests are developed some of which are themselves novel contributions to the stochastic dominance literature the empirical illustration documenting changes in sanitation deprivation in bangladesh showcases the measures ability to identify instances in which overall sanitation deprivation improved while leaving the poorest behind

ethically flexible measures of poverty this paper introduces new measures of both relative and absolute poverty using the notion of representative income of a community corresponding to the censored income distribution these new measures satisfy the monotonicity and transfer axioms proposed by sen 1976 in all cases
