inequality and mobility of household incomes in europe evidence from the echp in this article we want to shed light on two aspects of income mobility relative total income mobility using the estimator by fields and ok 1999 and equalization of long run incomes measured by the index of fields 2009 the cross country comparison shows a negative relationship between total relative mobility and long run income equalization this result is contrary to the intuition given by shorrocks 1978a who stated that higher relative mobility will cause higher equalization of incomes when the accounting period is extended

measuring movement of incomes we consider a small set of elementary properties for income movement measures and show that there is essentially only one measure that satisfies all of these properties the per capita aggregate change in log incomes we demonstrate next that this movement mobility measure has a number of appealing descriptive and normative properties and provide a formal generalization of our basic characterization theorem drawing from the related literature on poverty measurement finally we present here an empirical application in which we show by using our new measure that there has been a broad based increase in income movement in the united states between the 1970s and 1980s

how does land fragmentation affect off farm labor supply panel data evidence from china abstract this article provides a deeper theoretical understanding of the linkages between land fragmentation and off farm labor supply in china andinvestigates this relationship empirically in a more direct way than does the existing literature drawing upon a rural household panel data setcollected in zhejiang hubei and yunnan provinces from 1995 to 2002 we estimate the effects in two steps first we estimate the effect of landfragmentation on labor productivity second we estimate the effect of land fragmentation on off farm labor supply the production function resultsshow that land fragmentation indeed leads to lower agricultural labor productivity implying that land consolidation will make on farm work moreattractive and thus decrease off farm labor supply however the effect of land consolidation on off farm labor supply is not signi cant one likelyexplanation for this result may be the potentially imperfect labor markets jel classi cations j22 q15 q24 r23 keywords

educational inequality and intergenerational mobility in latin america a new database abstract the causes and consequences of the intergenerational persistence of inequality are a topic of great interest among various fields in economics however until now issues of data availability have restricted a broader and cross national perspective on the topic based on rich sets of harmonized household survey data we contribute to filling this gap by computing time series for several indexes of relative and absolute intergenerational education mobility for 18 latin american countries over 50 years and making them publicly available we find that intergenerational mobility is on average rising in latin america this pattern seems to be driven by the high upward mobility of children from low educated families at the same time there is substantial immobility at the top of the distribution significant cross country differences are observed and are associated with income inequality poverty economic growth public educational expenditures and assortative mating

an index of inequality with applications to horizontal equity and social mobility horizontal equity and social mobility are discussed in terms of a non utilitarian social welfare function which takes account of the process by which an ex ante distribution is mapped into an ex post distribution by the tax system for example an index of inequality is proposed which decomposes into two components corresponding to vertical and horizontal equity respectively a functional form for the social welfare function is derived for the purposes of empirical work and an application to data for 5895 uk households is presented the paper contains a theoretical application of the index to a model of optimal taxation it is conventional to assess the merits of alternative public policies in terms of a trade off between equity and efficiency in practice however a change in say the tax system involves three effects first it may have incentive or disincentive effects leading to efficiency gains or losses secondly it may alter the distribution of welfare levels thirdly it may alter the ranking of individuals or households within the distribution these three effects correspond to efficiency vertical equity and we shall argue certain aspects of horizontal equity respectively and any assessment of a tax change must take into account all three the principal assumption of this paper is that government is concerned about the trade off between these three effects a strict utilitarian is concerned only with the consequences of an action and in the evaluation of a particular reform a utilitarian measure of social welfare is defined over the vector of ex post utilities no account is taken of the process by which the vector of ex ante utilities is mapped into the ex post vector and no ethical status is awarded to the ex ante distribution one does not have to adopt an entitlement theory of justice to believe that the utilitarian approach may ignore some relevant considerations such as the fairness of the redistributive process a striking example of this arises in the model used by mirrlees 11 to examine optimal income taxation in that model individuals have identical preferences defined over consumption and leisure and differ only in respect of their potential wage rates or ability levels clearly in the absence of taxation individual utility is an increasing function of ability suppose the government uses redistributive lump sum taxes to achieve the first best optimum then as mirrlees 11 12 shows the first best optimum for a utilitarian social welfare

welfare distributional change and the measurement of social mobility a new approach to the measurement of welfare distributional change and social mobility is developed the novel feature of this model is the use of price dependent measures of individual and social welfare in evaluating t he magnitude and direction of the movement in the distribution in addition the proposed indexes of mobility are decomposed into the sum of between group and w ithin group mobility each measure is implemented for the united states over the period 1947 1982 it is found that in each year society is upwardly mobile rela tive to the 1947 distribution copyright 1986 by mit press

normative indices for measuring social mobility this paper introduces relative and absolute indices of social mobility to each index there corresponds a different social welfare function when the symmetric mean of order 1 social welfare function is employed the relative index becomes the king 1983 index of social mobility

the effect of financial liberalization on the efficiency of credit allocation some evidence from korea abstract this paper examines korea s recent experience with financial liberalization to find empirical evidence for the mckinnon shaw hypothesis regarding the effect of financial liberalization on the allocative efficiency of credit this involves analyzing changes in the variation of average borrowing costs across different sectors and industries using consolidated balance sheets and income statements from firms it demonstrates that there has been a substantial improvement in the efficiency of credit allocation since 1980 when the korean government started to implement various financial liberalization reforms

income mobility profiles abstract an income mobility profile is a graphical tool to portray income mobility and identify the association between individual movements and initial status which despite its importance when assessing the social relevance of mobility is often discounted by aggregate mobility indices

the gini multi decomposition and the role of gini s transvariation application to partial trade liberalization in the philippines this article proposes a unified technique of the gini decomposition the gini multi decomposition is a combination of the income source decomposition and the subgroup decomposition this technique is applied on reference situation and simulated scenarios for partial trade liberalisation in philippines and is extended to different orderings to capture a wide range of between group indicators we simulate variations in income source distributions for seven educational groups in the philippines in order to measure the inequality variations between a reference situation and a post simulation one with positive externalities due to public expenditures on the private sector productivity

the concept and measurement of horizontal inequity abstract this paper discusses the concept of horizontal equity and presents three formal principles as a basis for making comparisons of the extent of horizontal inequity produced by different redistributions a condition analogous to the lorenz criterion used for inequality comparisons is established under which the horizontal inequities of redistributions can be ranked without recourse to a cardinal measure of inequity ordinal comparisons are not possible in many cases the three principles suggest three properties that reasonable measures of horizontal inequity should possess a class of measures which satisfies the properties is proposed most other existing measures are found not to satisfy them

cross country income mobility comparisons under panel attrition the relevance of weighting schemes this article aims to present an assessment of the effects of panel attrition on income mobility comparisons for some eu countries by using the european community household panel echp there are different possibilities of correcting the attrition problem by means of alternative longitudinal weighting schemes the sensitivity of mobility estimates to these attrition correction procedures is tested in this article our results show that echp attrition is characterized by a certain degree of selectivity but only affecting some variables and countries different probability models corroborate the existence of a certain nonrandom attrition the model chosen to construct the longitudinal weights to correct attrition offers up rather different results than those obtained when eurostat s longitudinal weights are used although attrition does not seem to have a great effect on aggregated mobility indicators it does have a decisive effect on decomposition exercises our tests reveal certain sensitivity of income

the meaning and measurement of income mobility abstract income mobility may be seen as arising from two sources i the transfer of income among individuals with total income held constant and ii a change in the total amount of income available in this paper we propose several sensible properties defining the concept of income mobility and show that an easily applicable measure of mobility is uniquely implied by these properties we also show that the resulting measure is additively decomposable into the two sources listed above namely mobility due to the transfer of income within a given structure and mobility due to economic growth or contraction finally these results are compared and contrasted with other mobility concepts and measures in the literature journal of economic literature classification numbers d31 d63

intergenerational exchange mobility and economic welfare the concepts of exchange and structural mobility are introduced and their relationship with the notion of equality of opportunity discussed it is then shown that exchange mobility can have an impact on social welfare when the utility of any one generation is dependent on the consumption levels of overlapping generations whether such consumption interrelationships imply a preference for mobility or the reverse depends on whether the marginal utility of current consumption is raised or lowered by an increase in the consumption level of the associated generation the rest of this paper examines these two cases in the context of a simple two class family model the analysis is concerned with the description of the optimal intergenerational behaviour within this framework in order to be able to say anything substantial however it is necessary to impose some restrictions on the structure of the utility function one restriction which has some appeal and which yields plausible patterns of optimal policy is that intergenerational links through the utility function be not too strong in a sense that is made specific in the paper imposing this condition one can show how intra generational equity is affected both by intergenerational considerations and by the inherited past where intragenerational transfers involve efficiency losses a simple tax model is examined the circumstances under which starting with no taxes the tax rates converge are worked out in both the cases where the utility function has a pro as well as an anti mobility bias finally a specific utility function is taken in which the fathers utility depends not only on his own consumption but also on the average consumption of his son and himself in this case the utility function has a pro mobility bias and one can evaluate the response of the long run tax rate to parameters that measure mobility and equality using a similation model one can also assess the speed of convergence and the sensitivity of the tax rates to the parameters

measures of distributional change an axiomatic approach in recent years a number of interesting papers have appeared in the general field of the analysis of changes in a frequency distribution the most common applications of such analysis are in the areas of income and wealth re distribution and the contributions have usually focussed on a particular specialised issue such as mobility of individuals within a structure or of horizontal inequity as opposed to vertical inequality implicit in the comparison of two distributions a number of approaches to each of these problems have been suggested and indeed several specific practical indices of mobility or inequity have been proposed 1 whilst some of these can be shown to have very useful features in their application it is probably fair to say that most derive from an ad hoc approach to the particular aspect of the problem on which the author had focussed it is interesting to note that comparatively few papers attempt to exploit the similarities involved in each of these issues all this contrasts rather sharply with the state of play in an obviously closely related game that of the measurement of inequality much of the essential foundation of the problem of measuring inequality as we presently understand it seems to be more or less sorted out in a systematic fashion roughly speaking what may be done is as follows given

on the evaluation of economic mobility this paper presents a framework for the evaluation and measurement of reversal and origin independence as separate aspects of economic mobility we show how that evaluation depends on aversion to multi period inequality aversion to inter temporal fluctuations and aversion to future risk we construct extended atkinson indices that allow us to quantify the relative impact of reversal and origin independence on welfare we apply our approach to the comparison of income mobility in germany and in the united states when aversion to inequality is the only consideration the us gains more from mobility than germany this reflects similar gains from reversal in the two countries but greater gains in the us from origin independence the introduction of aversion to intertemporal fluctuations and aversion to future risk makes the impact of mobility in the two countries more similar

the effect of financial liberalization on the capital structure and investment decisions of indonesian manufacturing establishments this article analyzes the consequences of financial liberalization using a large panel of indonesian manufacturing establishments it discusses whether financial reforms have had an impact on investment and on the allocation of credit and whether the effects differ depending on the type of firms the overall conclusion is that shifting from administrative toward market based allocation of credit has increased borrowing cost particularly for smaller firms but at the same time has benefited firms by giving them widened access to finance

welfare based income insecurity in the us and germany evidence from harmonized panel data this paper develops normative approaches for measuring individual level income insecurity using concepts derived from expected utility theory and prospect theory we build a suite of measures designed to capture various facets of psychologically distressing income risk we present an application for the us and germany from 1993 2013 employing conditionally heteroskedastic fixed effects models to generate predictive densities for future incomes our results reveal much higher levels of income risk in the us relative to germany which can be mostly attributed to a higher level of autonomous time invariant volatility state by state variations in liberal conservative political administrations partially explain our results and we find some evidence that trade exposure is a contributing factor in the us

investment in segmented capital markets bankers screening devices are identified to determine firms probability of borrowing in the formal segment of the capital market in pakistan incorporating this information investment functions are estimated using a two stage switching regressions model with endogenous switching it is concluded that firms that borrow in the formal markets behave according to the flexible accelerator model of investment while non borrowing firms plough back profits furthermore the former have higher capital output ratios and find it less difficult to adjust to their desired capital stocks compared to the latter investment determinants related to entrepreneurial and firm features are also identified

preferences for redistribution in the land of opportunities this paper explores how individual preferences for redistribution depend on future income prospects in addition to estimating the impact of individuals socioeconomic background and of their subjective perceptions of future mobility we employ panel data to construct dobjectivet measures of expected gains and losses from redistribution for different categories of individuals we find that such measures have considerable explanatory power and perform better than dgeneral mobilityt indexes we also find that preferences for redistribution respond to individual beliefs on what determines one s position in the social ladder ceteris paribus people who believe that the american society offers equal opportunities are more averse to redistribution d 2004 published by elsevier b v

stochastic dominance in mobility analysis abstract this paper introduces a technique for mobility dominance and compares the degree of earnings mobility of men in the usa from 1970 to 1995 the highest mobility is found in the 1975 1980 or 1980 1985 periods

inequality adjusted income growth we introduce and characterize a new measure of aggregate income growth that allows us to give more weight to individuals with lower individual income growth our measure includes several important measures of directional mobility encountered in the literature the empirical application compares the measure of income growth between the usa and germany and finds that giving more weight to individuals with lower income growth reverses the ranking

capital market imperfections before and after financial liberalization an euler equation approach to panel data for ecuadorian firms using a large set of panel data for ecuadorian firms the authors analyze the role of capital market imperfections in investment decisions and investigate whether the financial reforms introduced in the 1980s in ecuador succeeded in relaxing financial constraints to facilitate capital accumulation and growth the ecuadorian government removed administrative controls on the interest rate and eliminated or scaled down directed credit programs the model used here allows both for an increasing cost of borrowing as the degree of leverage increases and for a ceiling on leverage the econometric results suggest that both types of capital market imperfections are important for small and young firms but not for large and old firms moreover the estimated equations do not provide evidence that financial reform in ecuador has helped to relax these financial constraints

international income mobility abstract we perform a novel analysis of the international mobility of per capita gnp we find general but not unambiguous support for the notion that world income mobility increased between 1972 and 1992 counterpointing the increased inequality over this period

earnings distribution and inequality over time education versus relative position and cohort this paper constructs a theoretical model for analyzing the earnings distribution over time and provides an estimation procedure for the inequality of earnings over time the theoretical model incorporates gibrat s so called law of proportionate effect galton s regression toward the mean and serial correlation of the error terms under the condition that the density function of earnings for each age cohort in japan is distributed as log logistic an emphasis is placed upon comparison of the influence of the relative position in the distribution with the influence of education on earnings finally the coefficients of variation over time are presented copyright 1991 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

turnover activity in wealth portfolios we examine several subsets of the wealthiest individuals in the us and the uk that are compiled by forbes magazine and the sunday times since these are named subsets we can calculate the returns to wealth portfolios and calibrate a statistical equilibrium model of wealth distribution that accounts for the power law of wealth and the asymmetric laplace distribution of portfolio returns the model provides a relative measure of turnover activity that indicates how often changes in the composition of the wealthiest portfolios occur finally we investigate trends in equality mobility and turnover activity

measuring social mobility abstract the paper considers the ranking of mobility matrices in a simple markov model of social mobility the approach is the dynamic counterpart ot the static inequality ranking of income distributions by the lorenz curve the derived partial ordering is motivated by welfare considerations is shown to be equivalent to same intuitive mobility concepts and is used to screen some immobility indices the equivalence of the ranking with the permanent income lorenz ordering gives support to the claim that this approach is the natural extension of kolm s the optimal production of social justice in public economics j margolis and h guitton eds macmillan london 1969 atkinson s on the measurement of inequality j econ theory2 1970 244 263 and dasgupta sen and starrett s notes on the measurement of inequality j econ theory6 1973 180 187 approaches journal of economic literature classification numbers d31 d63 j62

measuring social mobility as unpredictability by associating mobility with the unpredictability of social states new measures of social mobility may be constructed we propose a family of three state by state and aggregate scalar predictability measures the first set of measures is based on the transition matrix the second uses a sampling approach and permits statistical testing of the hypothesis of perfect mobility providing a new justification for the use of the x2 statistic the third satisfies the demanding criterion of period consistency an empirical example demonstrates the usefulness of the new measures to complement existing ones in the literature

three meanings of intergenerational mobility we axiomatize three different motivations for being concerned about intergenerational mobility mobility as a description of movement as an indication of equality of opportunity and as an indication of equality of life chances these three motivations are shown to be incompatible none of the existing measures is acceptable as an indicator of equality of opportunity or equality of life chances we propose two new measures of intergenerational mobility which more adequately reflect these concerns

intergenerational health mobility an empirical approach based on the echp despite the importance of the study of health mobility few attempts have been made to measure intergenerational mobility not only in the european union but also in other countries such as united states this article is focused on the study of intergenerational health mobility using data from the european community household panel echp in particular the relationships between self assessed health of parents and their sons are analysed the evidence obtained suggests that in spain sons reported health depends significantly on the self assessed health of their fathers
