the effect of income on child development this study presents estimates of the effect of parental income on children s cognitive social and emotional development the effect of current income is small especially when income is treated as endogenous the effect of permanent income is substantially larger but relatively small when compared to the magnitude of recent policy induced changes in income family background characteristics play a more important role than income in determining child outcomes policies that affect family income will have little direct impact on child development unless they result in very large and permanent changes in income

regional tax competition evidence from french regions reulier e and rocaboy y regional tax competition evidence from french regions regional studies two mechanisms can lead to fiscal strategic interactions between local jurisdictions the first is due to the tax base mobility authorities use fiscal variables to attract new resources the second is related to information asymmetries between the politicians and the constituency to reduce these asymmetries voters can compare their fiscal situation with the one in neighbouring jurisdictions these two channels lead to what can be referred to as mobility led and information led tax competition this paper aims to discriminate between these two tax competition models in the case of the french regions the econometric tests suggest that when taxes are paid by voters the politicians in office seem to be involved in an information led tax competition while in the case of taxes paid by firms the mobility of the tax base seems to be the best way to explain strategic fiscal interactions reulier e et

the new role for the world bank the world bank was founded to address what we would today call imperfections in international capital markets its founders thought that countries would borrow from the bank temporarily until they grew enough to borrow commercially nac 1946 p 312 black 1952 some critiques and analyses of the bank are based on the assumption that this continues to be its role for example some argue that the growth of private capital flows to the developing world has rendered the bank irrelevant however we will argue that modern analyses should proceed from the premise that the world bank s central goal is and should be to reduce extreme poverty and that addressing failures in global capital markets is now of subsidiary importance the bank s stated goal is reducing poverty the overwhelming majority of bank subsidies from its shareholder countries go to the international development association ida its arm for making grants and highly concessional loans to the lowest income countries the bank s greatest impact comes from its role in the dramatic policy changes many developing countries have undertaken in multiple sectors that most economists would consider likely to reduce poverty either by increasing growth or promoting equity why might donor countries choose to work through an international organization to advance the goal of reducing poverty effective aid often involves

price indexes inequality and the measurement of world poverty i discuss the measurement of world poverty and inequality with particular attention to the role of purchasing power parity ppp price indexes from the international comparison project global inequality increased with the latest revision of the icp and this reduced the global poverty line relative to the us dollar the recent large increase of nearly half a billion poor people came from an inappropriate updating of the global poverty line not from the icp revisions even so ppp comparisons between widely different countries rest on weak theoretical and empirical foundations i argue for wider use of self reports from international monitoring surveys and for a global poverty line that is truly denominated in us dollars

information competition and markets one of the dominant characteristics of modern capitalist economies is the important role played by competition not the peculiar static form of pure price competition embodied in the arrow debreu model but rather a dynamic competition more akin to the kind of competition represented by sports contests and other races including patent races in recent years there have been several attempts to explain why firms often base the pay of their workers and managers on relative performance see for example edward lazear and sherwin rosen 1981 such compensation schemes become desirable when three conditions are satisfied a the input effort of workers managers must not be directly observable at least without cost thus firms must either expend resources to monitor inputs or devise reward structures in which compensation is a function of variables such as output or profits which are themselves functions of inputs but are less costly to observe b the relationship between input and output must be stochastic so that by observing output one cannot perfectly infer what the input was c finally the stochastic disturbances which affect the relationship between input and output of different firms must be correlated by looking at the performance of one worker relative to that of others one can make better inferences about his effort than one can make without using this information not only can competition provide a basis of comparison which enables the design of reward structures that can simultaneously provide a high level of incentives with relatively low level risk but compensation schemes based on relative performance have the further advantage of automatically adjusting incentives to changes in the economic environment we refer to this as built in flexibility in a first best world with perfect information concerning the nature of the technology but where it is still costly to monitor individuals activities the compensation scheme would vary from time to time as the environment changed such changes in the compensation scheme are costly to implement and the information required to do so is seldom available when a task is easier the individual s rewards for performing the task should be reduced if pay is based on relative performance although all individuals perform better when they exert the same level of effort their compensation is automatically adjusted thus teachers frequently grade on the curve and a significant fraction of the pay of successful salesmen often consists of bonuses based on relative performance

income dynamics and life cycle inequality mechanisms and controversies this study focuses on the transmission of inequality over the working life a model of constrained intertemporal choice is used to provide structure to the distributional dynamics of wages earnings income and consumption the mechanisms used to insure labour market shocks are examined in a partial insurance setting where the manner and scope for insurance depends on the access to credit the information available to consumers and the durability of income shocks drawing on recent research family labour supply the credit market and the tax system are all shown to play a key role these mechanisms vary in importance across different points of the life cycle and the business cycle 2014 the author s the economic journal published by john wiley sons ltd on behalf of royal economic society

the intergenerational earnings and income mobility of canadian men evidence from longitudinal income tax data our objective is to obtain an accurate estimate of the degree of intergenerational income mobility in canada we use income tax information on about 400 000 father son pairs and find intergenerational earnings elasticities to be about 0 2 earnings mobility tends to be slightly greater than income mobility but nonparametric techniques uncover significant nonlinearities in both of these relationships intergenerational earnings mobility is greater at the lower end of the income distribution than at the upper end and displays an inverted v shape elsewhere intergenerational income mobility follows roughly the same pattern but is much lower at the very top of the income distribution

aggregate consequences of limited contract enforceability we study a general equilibrium model in which entrepreneurs finance investment with optimal financial contracts because of enforceability problems contracts are constrained efficient we show that limited enforceability amplifies the impact of technological innovations on aggregate output this implies that economies with lower enforceability of contracts are characterized by greater macroeconomic volatility a key assumption for the amplification result is that defaulting entrepreneurs are not excluded from the market

the role of child health and economic status in educational health and labour market outcomes in young adulthood the ontario child health study provides the first opportunity in canada to assess directly the relationship between socio economic and health status in childhood and levels of completed schooling health status and labour market success in young adult hood we find that childhood health problems are negatively associated with educational attainment especially the probability of a university degree and the health status of young adults our results also imply that childhood health problems influence adult labour force outcomes especially for males mainly through adult levels of schooling and health jel classification 110

on measuring child costs with applications to poor countries the theoretical basis for measuring child costs is discussed and detailed consideration is given to two straightforward procedures for calculation engel s food share method and rothbarth s adult good method each of these methods embodies different definitions of child costs so that the same empirical evidence can generate quite different estimates depending on the method used it is shown that true costs are generally overstated by engel s method and understated by rothbarth s procedure although the latter unlike the former can provide a sensible starting point for cost measurement our estimates from sri lankan and indonesian data suggest that children cost their parents about 30 40 percent of what they spend on themselves

quality quantity and spatial variation of price this paper develops and implements a method for estimating price elasticities of demand using cross sectional household survey data geographically clustered households report unit values which when corrected for quality effects and for measurement error indicate the underlying spatial variation in prices and can be matched to variation in demand patterns a simple model of quality choice is proposed while the correction for measurement error exploits the clustered design of such surveys data from a 1979 household survey from the ivory coast are used to estimate price elasticities for beef meat fish cereals and starches copyright 1988 by american economic association

economic contests comparative reward schemes contests are situations in which an individual s reward depends on his performance relative to others students are graded on a curve the candidate with the most votes gets the political office the underling who performs best is promoted to the executive position contests are useful in dealing with indivisible rewards reducing monitoring costs and minimizing risks from common uncertainties they are employed to sort potential participants and once they have entered to induce appropriate effort from them with monitoring precision and prize spreads as potential choice variables optimal contest structures are derived for fair and unfair contests among equal and unequal participants the converse problems of climbing low ability individuals enter the contest designed for high ability candidates and slumming are shown to be manageable

the origins of state capacity property rights taxation and politics economists generally assume that the state has sufficient institutional capacity to support markets and levy taxes this paper develops a framework where policy choices in market regulation and taxation are constrained by past investments in legal and fiscal capacity it studies the economic and political determinants of such investments demonstrating that legal and fiscal capacity are typically complements the results show that among other things common interest public goods such as fighting external wars as well as political stability and inclusive political institutions are conducive to building state capacity some correlations in cross country data are consistent with the theory

economic status and health in childhood the origins of the gradient the well known positive association between health and income in adulthood has antecedents in childhood not only is children s health positively related to household income but the relationship between household income and children s health becomes more pronounced as children age part of the relationship can be explained by the arrival and impact of chronic conditions children from lower income households with chronic conditions have worse health than do those from higher income households the adverse health effects of lower income accumulate over children s lives part of the intergenerational transmission of socioeconomic status may work through the impact of parents income on children s health

measuring poverty in a growing world or measuring growth in a poor world the extent to which growth reduces global poverty has been disputed for 30 years although there are better data than ever before controversies are not resolved a major problem is that consumption measured from household surveys which is used to measure poverty grows less rapidly than consumption measured in national accounts in the world as a whole and in large countries particularly india china and the united states in consequence measured poverty has fallen less rapidly than appears warranted by measured growth in poor countries one plausible cause is that richer households are less likely to participate in surveys but growth in the national accounts is also upward biased and consumption in the national accounts contains large and rapidly growing items that are not consumed by the poor and not included in surveys so it is possible for consumption of the poor to grow less rapidly than national consumption without any increase in measured inequality current statistical procedures in poor

saving and growth evidence from micro data abstract this paper examines whether the observed cross country correlation between aggregate saving rates and economic growth can be explained by models in which higher growth increases saving rates rather than the other way around there are two explanations why higher growth might increase saving first life cycle theory implies that higher growth will increase the life time wealth of younger savers relative to older dissavers thereby increasing the aggregate saving rate second models of consumption with habit formation imply that consumption responds slowly to unexpected income growth so unanticipated growth can produce a higher saving rate at least in the short run i assess these explanations using time series of cross sections of household surveys from four countries the us britain taiwan and thailand i find evidence that higher growth will produce only small increases in aggregate saving rates

political decentralization and corruption evidence from around the world abstract how does political decentralization affect the frequency and costliness of bribe extraction by corrupt officials previous empirical studies using subjective indexes of perceived corruption and mostly fiscal indicators of decentralization have suggested conflicting conclusions in search of more precise findings we combine and explore two new data sources an original cross national data set on particular types of decentralization and the results of a firm level survey conducted in 80 countries about firms concrete experiences with bribery in countries with a larger number of government or administrative tiers and given local revenues a larger number of local public employees reported bribery was more frequent when local or central governments received a larger share of gdp in revenue bribery was less frequent overall the results suggest the danger of uncoordinated rent seeking as government structures become more complex

the developing world is poorer than we thought but no less successful in the fight against poverty a new data set on national poverty lines is combined with new price data and almost 700 household surveys to estimate absolute poverty measures for the developing world we find that 25 of the population lived in poverty in 2005 as judged by what poverty typically means in the world s poorest countries this is higher than past estimates substantial overall progress is still indicated the corresponding poverty rate was 52 in 1981 but progress was very uneven across regions the trends over time and regional profile are robust to various changes in methodology though precise counts are more sensitive

looking for boy girl discrimination in household expenditure data the ability to test for discrimination in the allocation of goods between boys and girls is hampered by a lack of data on intrahousehold distribution the analysis presented here allows inferences about intrahousehold allocation to be made from householdlevel expenditure data for a given level of income families with children will spend less on adult goods in order to purchase children s goods if household purchasing favors boys over girls smaller expenditures on adult goods would be made by families with boys as compared with those with girls a method for determining adult goods is described and the procedure for detecting gender bias is applied to data from c6te d lvoire and thailand the data show no evidence of discriminatio n between boys and girls in c6te d lvoire and a small and statistically insignificant bias in favor of boys in thailand how commodities are allocated among the members of a household has recently occasioned a good deal of interest assessments of poverty and income distribution based on household incomes or expenditures will be misleading if allocation within the household is unequal the position of women and girls has been of particular concern and there is a considerable amount of empirical evidence much of it from the indian subcontinent that documents discrimination against females see in particular bhagwati 1973 sen 1984 sen and sengupta 1983 miller 1981 bardhan 1982 and kynch and sen 1983 as well as survey papers by behrman 1987 and harriss 1987 much of the evidence is concerned with measurements of nutritional outcomes mortality and health status rather than with the direct allocation of goods by gender the difficulty in trying to determine the intrahousehold allocation of goods is that household budget surveys the obvious source of data record consumption not of individuals but of households and while attempts can be made to the author is a professor of public affairs and of economics and international affairs at princeton university and is a consultant to the population and human resources department of the world bank the author thanks dwayne benjamin who provided for excellent research assistance he is grateful to him and to members of the economic growth center at yale university for helpful comments this is a revised and shortened version of living standards measurement study working paper 39 the allocation of goods within the household adults children and gender june 1987 the results from thailand were not included in the working paper 1989 the international bank for reconstruction and development the world bank

socioeconomic status and child health why is the relationship stronger for older children case lubotsky and paxson 2001 show that the well known relationship between socio economic status ses and health exists in childhood and grows more pronounced with age however in cross sectional data it is difficult to distinguish between two possible explanations the first is that low ses children are less able to respond to a given health shock the second is that low ses children experience more shocks we show using panel data on canadian children that 1 the gradient we estimate in the cross section is very similar to that estimated previously using u s children 2 both high and low ses children recover from past health shocks to about the same degree and 3 that the relationship between ses and health grows stronger over time mainly because low ses children receive more negative health shocks in addition we examine the effect of health shocks on math and reading scores we find that health shocks affect test scores and future health in very similar ways our results suggest that public policy aimed at reducing ses related health differentials in children should focus on reducing the incidence of health shocks as well as on reducing disparities in access to palliative care

trade tastes and nutrition in india this paper introduces habit formation into an otherwise standard model of international trade household tastes evolve over time to favor foods consumed as a child the opening of trade causes preferred goods to rise in price as these were relatively inexpensive in autarky neglecting the correlation between tastes and agro climatic endowments overstates the short run nutritional gains from agricultural trade liberalization and masks potential caloric losses for laborers i examine the predictions of this model of trade with habit formation using household survey data from india both by looking across indian regions and by examining the consumption patterns of inter state migrants

law regulation and the business climate the nature and influence of the world bank doing business project the importance of a well functioning legal and regulatory system in creating an effective market economy is now widely accepted one flagship project that tries to measure the environment in which businesses operate in countries across the world is the world bank s doing business project which was launched in 2002 this project gathers quantitative data to compare regulations faced by small and medium size enterprises across economies and over time the centerpiece of the project is the annual doing business report it was first published in 2003 with five sets of indicators for 133 economies and currently includes 11 sets of indicators for 189 economies the report includes a table that ranks each country in the world according to its scores across the indicators the doing business project has become a major resource for academics journalists and policymakers the project also enjoys a high public profile with close to ten million hits on its website each year with such interest it s no surprise that the doing business report has come under intense scrutiny in 2012 following discussions by its board the world bank commissioned an independent review panel to evaluate the project on which i served as a member in this paper i first describe how the doing business project works and illustrate with some of the key findings of the 2015 report next i address what is valuable about the project the criticisms of it and some wider political economy issues illustrated by the report

why is consumption so smooth for thirty years it has been accepted that consumption is smooth because permanent income is smoother than measured income this paper considers the evidence for the contrary position that permanent income is in fact less smooth than measured income so that the smoothness of consumption cannot be straightforwardly explained by permanent income theory the paper argues that in postwar u s quarterly data consumption is smooth because it responds with a lag to changes in income

tax competition relative performance and policy imitation rather than about their absolute payoffs governments in fiscal competition often seem to care about their performance relative to other governments moreover they often appear to mimic policies observed elsewhere i study such behavior in a standard tax competition game both with relative payoff concerns and for imitative policies evolutionary stability for games with finitely many players is the appropriate solution concept independently of the number of jurisdictions involved an evolutionarily stable tax policy coincides with the competitive outcome of a tax competition game with infinitely many players it thus involves drastic efficiency losses

a theory of yardstick competition in the typical regulatory scheme a franchised monopoly has little incentive to reduce costs this article proposes a mechanism in which the price the regulatedfirm receives depends on the costs of identical firms in equilibrium each firm chooses a socially efficient level of cost reduction the mechanism generalizes to cover heterogeneous firms with observable differences medicare s prospective reimbursement of hospitals by using diagnostically related groups is a scheme very similar to the one outlined here

economies of scale household size and the demand for food household scale economies are plausibly attributed to shared household public goods that make larger households better off at the same level of per capita resources larger households should therefore have higher per capita consumption of private goods such as food provided that they do not substitute too much toward the effectively cheaper public goods the evidence shows exactly the opposite data from rich and poor countries indicate that at constant per capita total expenditure the per capita demand for food decreases with household size and that it does so most in the poorest countries where substitution should be the least

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

price and income elasticities of residential energy demand in germany we apply a quadratic expenditure system to estimate price and expenditure elasticities of residential energy demand electricity and heating in germany using official expenditure data from 1993 to 2008 we estimate an expenditure elasticity for electricity of 0 3988 and of 0 4055 for space heating the own price elasticity for electricity is 0 4310 and 0 5008 in the case of space heating disaggregation of households by expenditure and demographic composition reveals that the behavioural response to energy price changes is weaker stronger for low income top income households there are considerable economies of scale in residential energy use but scale effects are not well approximated by the new oedc equivalence scale real increases in energy prices show a regressive pattern of incidence implying that the welfare consequences of direct energy taxation are larger for low income households the application of zero elasticities in assessments of welfare consequences of energy taxation strongly underestimates potential welfare effects the increase in inequality is 22 smaller when compared to the application of rich and disaggregated behavioural response patterns as estimated in this paper

decentralisation as an incentive scheme recent changes have introduced more decentralization in a number of traditionally centralized countries 1 in the case of france it is sometimes claimed that the 1982 1983 reform of subcentral government is of historical importance although the principles of that reform are not contested any more by the new majority elected in 1986 opinions still differ on a number of policy issues some of the issues are presented in this introductory section but the main purpose of this paper is not to expose or discuss in detail the problems of decentralization in france as argued in the second part of the introductory section the theoretical framework in which the policy issues of decentralization are usually discussed by economists is somewhat unsatisfactory in particular when applied to unitary states such as britain or france the bulk of the paper is devoted to the exploration of a different approach to decentralization it is not purported however that this approach could completely replace the more traditional one consequently when in the concluding section we return briefly to the policy issues identified here this is to be read as a preliminary attempt to evaluate the relevance of the reasoning developed in the paper

decentralization as a constraint to leviathan a panel cointegration analysis this paper extends the empirical literature about the effects of fiscal decentralization on the growth of government along three dimensions it distinguishes between the effects of the level of decentralization from the way local governments finance their expenditures common pool versus own resources it uses a panel cointegration approach to separate the long run effects of decentralization from the short run dynamics and it extends and revises the datasets generally used in these empirical analyses the results show that the amount of revenue raised by sub national governments leads to a long term fall in the size of government but grants have the opposite effect in addition a greater decentralization of expenditure leads to greater overall spending when the short term is considered these influences work slowly as the speed of adjustment towards the desired government size is relatively sluggish in addition in the short run there is also a clear effect from the role of local revenue raising powers that stimulates the growth of government these results appear robust to changes in the composition of the variables countries and periods included the sample

tuition fees and equality of university enrolment abstract the relationship between tuition fee changes and the university enrolment of youth by parental income group in canada is investigated comparisons between youth from canadian provinces that increased tuition fees sharply in the 1990s and youth from provinces that instituted fee freezes were integral to identifying the relationship tuition fee increases coincided with reductions in the university enrolment of low income youth but with significantly smaller changes in the university enrolment of other youth the relationships between government funding of universities and cohort size and university enrolments are also analyzed

fiscal illusion and the grantor government empirical studies indicate that unconditional intergovernmental grants have a flypaper effect several authors have modeled recipient government spending under fiscal illusion to explain this phenomenon in short grants reduce the perceived marginal cost of recipient government output this paper develops a more general model of illusion that incorporates the grantor government thereby eliminating inconsistencies encountered in previous models the more general model implies that grant finance increases the perceived marginal cost of grantor government output thus grant induced illusion should have two effects an increase in recipient output and a decrease in grantor output the empirical work supports this hypothesis

saving and inflation some international evidence abstract this note contains empirical results for the disequilibrium saving function specification in which uncertainty about relative prices in a cross section sense plays a major role quarterly time series evidence from several oecd countries over the period 1967 ii 1980 iii lies in striking conformity with the view suggested particularly by deaton that there is a positive relationship between unanticipated inflation and the saving ratio

individual income incomplete information and aggregate consumption individual income is much more variable than aggregate per capita income i argue that aggregate information is therefore not very important for individual consumption decisions and study models of life cycle consumption in which individuals react optimally to their own income process but have incomplete or no information on economy wide variables since individual income is less persistent than aggregate income consumers will react too little to aggregate income variation aggregate consumption will be excessively smooth since aggregate information is slowly incorporated into consumption aggregate consumption will be autocorrelated and correlated with lagged income on the other hand the model has the same prediction for micro data as the standard permanent income model the second part of the paper provides empirical evidence on individual and aggregate income processes different models for individual income are fit to quarterly data from the survey of income and program participation making various adjustments for measurement error calibrating the consumption model using the estimated parameters for the income process yields predictions which qualitatively correspond to the empirical findings for aggregate consumption but do not match them well in magnitude

red tape and delayed entry does cutting red tape foster entrepreneurship in industries with the potential to expand we address this question by combining the time needed to comply with government entry procedures in 45 countries with industry level data on employment growth and growth in the number of establishments during the 1980s our main empirical finding is that countries where it takes less time to register new businesses have seen more entry in industries that experienced expansionary global demand and technology shifts our estimates take into account that proxying global industry shifts using data from only one country or group of countries with similar entry regulations will in general yield biased results

the effects of financial development in the short and long run theory and evidence from india abstract although many view financial access as a means of reducing poverty or increasing growth empirical studies have produced contradictory results one problem is that most studies cover only a short time frame and do not consider dynamic effects i show that introducing credit in a general model of intertemporal consumption creates a boom in consumption and reduces poverty initially but eventually reduces mean consumption because credit substitutes for precautionary wealth using new consistent consumption data that cover a much longer time period than most studies my empirical findings show that increased access to bank branches in rural india increased consumption initially and reduced poverty but consumption later fell and poverty rose the long term effect is still positive however suggesting that credit may have a beneficial role beyond consumption smoothing

incumbent behavior vote seeking tax setting and yardstick competition this paper develops a model of the political economy of tax setting in a multijurisdictional world where voters choices and incumbent behavior are determined simultaneously voters are assumed to make comparisons between jurisdictions to overcome political agency problems this forces incumbents into a yardstick competition in which they care about what other incumbents are doing we provide a theoretical framework and empirical evidence using u s state data from 1960 to 1988 the results are encouraging to the view that vote seeking and tax setting are tied together through the nexus of yardstick competition

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

risk sharing in private information models with asset accumulation explaining the excess smoothness of consumption we study testable implications for the dynamics of consumption and income of models in which first best allocations are not achieved because of a moral hazard problem with hidden saving we show that in this environment agents typically achieve more insurance than that obtained under self insurance with a single asset consumption allocations exhibit excess smoothness as found and defined by campbell and deaton 1989 we argue that excess smoothness in this context is equivalent to a violation of the intertemporal budget constraint considered in a bewley economy with a single asset we also show parameterizations of our model in which we can obtain a closed form solution for the efficient insurance contract and where the excess smoothness parameter has a structural interpretation in terms of the severity of the moral hazard problem we present tests of excess smoothness applied to u k microdata and constructed using techniques proposed by hansen roberds and sargent 1991 to test the intertemporal budget constraint our theoretical model leads us to interpret them as tests of the market structure faced by economic agents we also construct a test based on the dynamics of the cross sectional variances of consumption and income that is in a precise sense complementary to that based on hansen roberds and sargent 1991 and that allows us to estimate the same structural parameter the results we report are consistent with the implications of the model and are internally coherent

interactions in local governments spending decisions evidence from portugal costa h goncalves veiga l and portela m interactions in local governments spending decisions evidence from portugal regional studies this paper aims to analyse the degree of interaction between portuguese municipalities expenditure levels by estimating a dynamic panel model based on jurisdictional reaction functions the analysis is performed for all 278 portuguese mainland municipalities from 1986 to 2006 using alternative ways to measure neighbourhood results indicate that local governments spending decisions are significantly and positively influenced by the actions of neighbouring municipalities attempts to identify the sources of interaction allow it to be concluded that they are due to spillovers that require coordination in expenditure items and to mimicking behaviour possibly to attract households and firms

yardstick competition fiscal disparities and equalization abstract the theory of political yardstick competition states that a comparison of public service levels and tax rates with those in nearby jurisdictions can provide voters with a useful instrument to assess politicians performance however we argue that fiscal disparities bias this yardstick and that this bias may be removed through fiscal equalization

does legal enforcement affect financial transactions the contractual channel in private equity analyzing 210 developing country private equity investments we find that transactions vary with nations legal enforcement whether measured directly or through legal origin investments in high enforcement and common law nations often use convertible preferred stock with covenants in low enforcement and civil law nations private equity groups tend to use common stock and debt and rely on equity and board control transactions in high enforcement countries have higher valuations and returns while relying on ownership rather than contractual provisions may help to alleviate legal enforcement problems these results suggest that private solutions are only a partial remedy

estimating real income in the united states from 1888 to 1994 correcting cpi bias using engel curves this paper provides the first estimates of overall cpi bias prior to the 1970s and new estimates of bias since the 1970s it finds that annual cpi bias was 0 1 percent between 1888 and 1919 and rose to 0 7 percent between 1919 and 1935 annual cpi bias was 0 4 percent in the 1960s and then rose to 2 7 percent between 1972 and 1982 before falling to 0 6 percent between 1982 and 1994 the findings imply that we have underestimated growth rates in true income in the 1920s and 1930s and in the 1970s

quadratic engel curves and consumer demand this paper presents a model of consumer demand that is consistent with the observed expenditure patterns of individual consumers in a long time series of expenditure surveys and is also able to provide a detailed welfare analysis of shifts in relative prices a nonparametric analysis of consumer expenditure patterns suggests that engel curves require quadratic terms in the logarithm of expenditure while popular models of demand such as the translog or the almost ideal demand systems do allow flexible price responses within a theoretically coherent structure they have expenditure share engel curves that are linear in the logarithm of total expenditure we derive the complete class of integrable quadratic logarithmic expenditure share systems a specification from this class is estimated on a large pooled data set of u k households models that fail to account for engel curvature are found ro generate important distortions in the patterns of welfare losses associated with a tax increase

vertical competition in the spanish national health system nhs in unitary states competitive decentralisation structures can take place by increasing the visibility of politically accountable jurisdictions in certain policy responsibilities such as health care drawing from the spanish decentralisation process we examine the mechanisms and determinants of vertical competition in the development of health policies in the spanish national health system the spanish example provides qualitative evidence of vertical competition that assimilates government outcomes of unitary states to that of federal structures the spanish experience indicates that the specific vertical competition mechanisms in place until 2002 are likely to be responsible for significant policy innovation and welfare state development

a race to the bottom in labor standards an empirical investigation abstract one of the concerns over globalization is that as nations compete for investment they relax labor standards to attract firms using spatial estimation on panel data for 135 countries over 17 years we find that the labor standards in one country are positively correlated with those elsewhere i e a cut in labor standards in other countries reduces labor standards in the country in question this interdependence is more evident in labor practices i e enforcement than in labor laws further while we find evidence of competition in both developed and developing countries it is strongest among developing countries with weak standards
