the futile quest for a grand explanation of long run government expenditure this paper carries out a critical reappraisal of the two contending theories purporting to explain long run government spending wagner s law and different variants of the ratchet effect we analyze data spanning from the early 19 th century until the present day in sweden and the united kingdom hence in contrast to previous studies we evaluate the validity of wagner s law and the ratchet effect hypothesis over a very long time period starting at the beginning of industrialization cointegration analysis is used to investigate the long run relationships between government expenditure and gdp focusing on sub periods and structural breaks moreover we test the ratchet effect hypothesis by estimating models which allow for asymmetric adjustment according to our main results wagner s law does not hold in the long run although the data are consistent with wagner s law between roughly 1860 and the mid 1970s this can be traced to the formation of the modern public sector including the introduction of public education health care and so forth yet wagner s law did not hold during the initial industrialization phase before 1860 and in recent periods gdp only affects the government spending share when we control for population age structure finally we find some evidence of asymmetric adjustment in the uk particularly in the post wwii period however the ratchet effect is not a general cause of the growth of government spending

more on estimation risk and simple rules for optimal portfolio selection for the risk averse investor consideration of estimation risk is important in selecting an expected utility maximizing portfolio it has previously been shown that the composition of the tangency portfolio is unaffected by the recognition of estimation risk if the full covariance model is used alternatively if the market model is used the composition of the tangency portfolio has been shown to be affected by the recognition of estimation risk however as is demonstrated in this paper the effect will generally not be as substantive as previously believed and in many situations can be safely ignored in order to determine the composition and location of an efficient frontier from which an optimal portfolio will be selected the investor must employ estimates of expected returns variances and covariances for the set of securities under consideration if the investor simply treats the estimated parameter values for the securities as true parameter values then estimation risk will have been ignored and as shown by barry 1 and klein and bawa 14 15 a suboptimal portfolio will most likely have been selected bawa brown and klein 6 and klein and bawa 14 discuss the effects of estimation risk on the selection of an optimal portfolio from a set of risky assets and note that the location but not the composition of the efficient frontier changes when estimation risk is recognized if security returns are generated by a stationary multivariate normal distribution for which the investor has a diffuse prior furthermore brown 8 has shown these results to be robust for severe misspecification of the underlying multivariate distribution of returns e g assuming it to be normal when in actuality it is student t with small degrees of freedom this paper is concerned with the effects of estimation risk on the composition of the tangency portfolio derived from a set of risky assets and a risk free asset under the assumption that the investor has a diffuse prior 1 barry 2 bawa and brown 4 and brown 7 have shown analytically that the composition of the tangency portfolio is unaffected by estimation risk if the full covariance model is used chen and brown 10 have expanded upon the work of brown 9 and have argued that if security returns are generated by the market model then the composition of the tangency portfolio will be substantively different when estimation risk is recognized

analysts forecasts as proxies for investor beliefs in empirical research abstract we analyze how analysts forecasts relate to investor beliefs and describe the implications of these relations for price and volume reactions to earnings surprises we show that dispersion among forecasts does not fully capture investor uncertainty we also show how the relations between market reactions and forecast properties differ under the alternative assumptions of exogenous and endogenous private information acquisition finally the analysis suggests refined tests for volume reactions at the time of an announcement our results indicate that the model is useful for understanding and interpreting empirical work and developing empirical tests of market reactions to announcements

the 1990s rise in swedish earnings inequality persistent or transitory this article decomposes the rise in the cross sectional variance of male annual earnings in sweden between 1991 and 1999 into its persistent and transitory components the results show that the persistent component accounts for basically all of the increase in earnings dispersion this implies that the answer to the 1990s trend reversal in swedish earnings inequality is to be found in explanations that focus on persistent changes in the labour market such as changes in the price of skills

is globalisation undermining the welfare state this paper analyses the evolution of the welfare states in the majority of oecd countries during the pre globalisation 1946 80 and globalisation 1980 2000 periods our purpose is to find out whether globalisation has produced a convergence towards a smaller welfare state funded increasingly by non mobile factors such as labour property and consumption rather than by mobile factors such as capital the data presented here challenge the claims about such a convergence showing that social public expenditures and public employment have continued to expand during the globalisation period in most oecd countries we also show that the welfare states remain rooted in the political traditions that have governed them copyright 2004 oxford university press

earnings instability and earnings inequality of males in the united states 1967 1991 although much research has focused on recent increases in annual earnings inequality in the united states the increases could have come from either of two sources the distribution of lifetime earnings could have become more unequal or the receipt of lifetime earnings could have become more unstable based on an analysis of the 1968 92 panel study of income dynamics we find that lifetime earnings inequality increased during the early 1980s and that earnings instability increased during the 1970s we also examine how these trends are related to changes in the distribution of wages and hours and the returns to education

job polarization and task biased technological change evidence from sweden 1975 2005 this paper shows that between 1975 and 2005 sweden exhibited a pattern of job polarization with expansions of the highest and lowest paid jobs compared to middle wage jobs the most popular explan

a new measure of earnings forecast uncertainty abstract relying on the well established theoretical result that uncertainty has a common and an idiosyncratic component we propose a new measure of earnings forecast uncertainty as the sum of dispersion among analysts and the variance of mean forecast errors estimated by a garch model the new measure is based on both common and private information available to analysts at the time they make their forecasts hence it alleviates some of the limitations of other commonly used proxies for forecast uncertainty in the literature using analysts earnings forecasts we find direct evidence of the new measure s superior performance

dynamics in transitory and permanent variation of wages in germany abstract we employ covariance structure models to decompose the cross sectional variance of male wages in germany into its permanent and transitory parts we find that the steep growth of cross sectional inequality during the early 2000s is predominantly driven by transitory factors

the welfare costs of union wage compression abstract this paper calculates the quantitative significance of the welfare costs of union wage compression this is done in a dynamic general equilibrium model with overlapping generations where agents choose both schooling human capital and assets physical capital the labor market in this model is characterized as a right to manage contract which allows unions to compress wage differentials between high and low skilled workers by implementing a binding minimum wage this paper shows that when labor markets are competitive even low levels of wage compression lead to large welfare losses since wage compression creates costly unemployment among low skilled workers the effect of wage compression on the supply of skilled labor however is rather small since the disincentive effect of a lower high skilled wage is to a large extent offset by a lower opportunity cost of schooling due to higher unemployment

equilibrium pricing and portfolio composition in the presence of uncertain parameters abstract we analyze the effect of parameter uncertainty on equilibrium asset prices for the symmetric case when the amount of estimation risk is the same for all securities the existing literature argues that parameter uncertainty is largely irrelevant for equilibrium our results differ we find that symmetric estimation risk affects equilibrium values of relative asset prices expected returns market weights and betas

measuring forecast uncertainty by disagreement the missing link using a standard decomposition of forecast errors into common and idiosyncratic shocks we show that aggregate forecast uncertainty can be expressed as the disagreement among the forecasters plus the perceived variability of future aggregate shocks thus the reliability of disagreement as a proxy for uncertainty will be determined by the stability of the forecasting environment and the length of the forecast horizon using density forecasts from the survey of professional forecasters we find direct evidence in support of our hypothesis our results support the use of garch type models rather than the ex post squared errors in consensus forecasts to estimate the ex ante variability of aggregate shocks as a component of aggregate uncertainty copyright 2010 john wiley sons ltd

predisclosure information firm capitalization and security price behavior around earnings announcements several studies on the relationship between earnings reports and security price behavior provide evidence suggesting that a significant portion of the information revealed through earnings reports is reflected in security prices prior to the report month e g ball and brown 1968 and brown and kennelly 1972 this has been attributed at least partly to the existence of other more timely sources of information which allow market agents to forecast earnings prior to their release the evidence above reflects an average finding across all firms one question of interest is whether there are significant systematic crosssectional differences in the security price reactions to earnings announcements of firms which are associated with specific firm characteristics that lead to differential amounts of predisclosure information this study focuses on firm size capitalization as one such characteristic a firm

the income and tax share of very high income households 1960 1995 this paper presents new information on the fraction of adjusted gross income and of wages and salaries that is reported by taxpayers in the top one half of one percent of the income distribution this corresponds to roughly five hundred thousand households in the late 1990s this paper relies on data from the treasury s individual income tax model for the period 1960 1995 the definition of adjusted gross income is standardized so that changes in the tax law do not affect the measured concentration of agi the results suggest that the share of agi reported by the highest income households increased significantly between the early 1980s and the mid 1990s with most of the increase taking place in the years immediately following the tax reform act of 1986 while we find some evidence of transitory changes in the concentration of income around major tax changes which may be the result of income retiming by high income taxpayers re timing does not seem to explain most of the changes since 1986 this abstract was borrowed from another version of this item

information and diversity of analyst opinion this paper examines problems in the use of divergence of analyst opinion as a proxy for estimation risk in empirical studies of security returns and asset pricing models we demonstrate that diversity of opinion can increase even though the amount of private information increases and we show that diversity of opinion may overstate estimation risk if the capital market aggregates the information held by investors we produce empirical results consistent with our conclusions specifically we find that divergence of opinion can produce measures of estimation risk that are inconsistent with a received proxy for estimation risk and with observed common stock returns

trends in the transitory variance of earnings in the united states we decompose the rise in cross sectional variance of male annual earnings in the united states from 1969 to 1996 into permanent and transitory components we find that the variance of permanent earnings began rising in the the late 1970s and has continued to rise in the 1980s the variance of transitory earnings also rose in the 1980s but declined in the 1990s there are lags in the earnings process which require a structural model to pinpoint the exact calendar times at which the changes in trends occurred

prices productivity and wage bargaining in open economies according to the standard union bargaining model unemployment benefits should have big effects on wages but product market prices and productivity should play no role in the wage bargain we formulate an alternative strategic bargaining model where labour and product market conditions together determine wages a wage equation is derived and estimated on aggregate data for four nordic countries wages are found to depend not only on unemployment and the replacement ratio but also on productivity international prices and exchange rates there is evidence of considerable nominal wage rigidity exchange rate changes have large and persistent effects on competitiveness

the informal sector elephant abstract different analysts have used the term informal sector to mean different things a data set with 2 200 small enterprises chosen using random procedures in seven countries makes it possible to test the relationships between different measures the analysis finds only limited parallels between definitions based on size on registration on conformity to fiscal and other regulations and on degrees of modernization wide variations appear from one country to another the term may be appropriate for examination of individual countries especially if the analyst defines it precisely but its use in multicountry analysis is fraught with difficulties

policies for a heterogeneous informal sector in latin america abstract the concept of the informal sector has gained increasing acceptance in latin america some 30 million persons now work outside the modern economy in low productivity jobs with marginal incomes many of them are living in poverty international and national policy makers have become aware of the political and economic consequences of this phenomenon and are seeking ways to improve returns and incomes the sector however is composed of different kinds of activities each with its own problems which need to be addressed in different ways policy planners should bear this in mind as they seek solutions the paper recommends three types of measures providing productive assistance to informal enterprises supporting informal sector workers and revising regulations that govern informal sector activities

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

formal measures of the informal sector wage gap in mexico el salvador and peru using comparable micro level data from three countries we ask what type of person works in the informal sector and whether informal workers earn lower wages than observationally equivalent workers in the formal sector the characteristics of informal workers are similar across countries surprisingly when we control for these personal characteristics we find a significant wage premium associated with formal employment in el salvador and peru but a premium associated with work in the informal sector in mexico a model of endogenous selection offers little help in explaining the differences in wage patterns the research casts doubt on the received wisdom that the informal sector always and everywhere is a poorly paid but easily entered refuge for those who have no other employment opportunities this abstract was borrowed from another version of this item

employment and poverty during economic restructuring the case of bogota colombia bogota is seemingly a positive example of what restructuring and sensible macroeconomic policy can bring to latin america despite liberalisation and a vast increase in the number of people seeking work unemployment rates have fallen large numbers of new jobs have been created principally in the informal sector there seems little real doubt that since 1970 poverty in bogota has become both less common and less serious however if there is less poverty it is principally because of demographic change adults form a larger proportion of the labour force and more of those adults are working poverty has been cut by the huge rise in labour participation fewer people are hungry but people are also a great deal busier nor has the degree of income inequality been reduced

the rise of the modern welfare state ideology institutions and income security analysis and evidence in the 25 year period between 1960 and 1985 there was a great expansion of welfare state programs throughout the west the fraction of gdp accounted for by social expenditures doubled in much of europe and grew by 40 50 in many other oecd nations after 1985 growth in social insurance programs slowed relative to other parts of the economy this paper explores the extent to which institutions and ideological shifts may have accounted for the period of rapid growth for differences in the extent of that growth and for the subsequent reduction in the growth rates of social insurance programs

the assessment economic policy and social democracy the economic objectives of recent governments of the left were full employment reducing inequality and enhancing economic performance and democratic control by measures of planning and socialization the economic inheritance was difficult stagnant investment high unemployment in a number of cases and inflation higher than that of competitors the generalized productivity slow down slow growth and the drive to reduce inflation represented an unfavourable context the supply side interventions atrophied were abandoned or reversed employment performance was poor overall and sometime s disastrous some extensions of the welfare state were achieved and major increases in inequality were avoided but this record was hardly exceptional globalization is often blamed for such disappointments here the emphasis is on the inherent difficulties of the social democratic project containing distributional conflict other than by unemployment sustaining support for redistribution when living standards are stagnating and con straining business while relying on it to maintain high investment

crime and unemployment in turbulent times we use the exceptional variation in municipality level unemployment in sweden during the 1990s to identify the effect of unemployment on crime our findings are as follows i there is a statistically and economically significant effect of general unemployment on the incidence of burglary auto theft and drug possession ii we find no evidence for the popular view that youth unemployment matters for crime iii prime aged unemployment is robustly correlated with main categories of youthful crimes a finding consistent with the idea that unstable life conditions of parents have adverse spillover effects on the life choices of their children jel j00 k4

estimation risk and simple rules for optimal portfolio selection elton gruber and padberg egp 6 7 have recently simplified the process of constructing optimal portfolios by developing simple criteria for optimal portfolio selection which do not involve use of mathematical programming their simple decision rules permit one to determine easily which securities to include in an optimal portfolio and how much to invest in each however in practical applications of theoretical models sample estimators are usually treated as if they were true values of unknown parameters as a result the effect of the standard errors of sample estimators on decision rules are completely ignored bawa brown and klein 1 have shown that what is optimal in the absence of estimation risk is not necessarily optimal or even approximately optimal in the presence of estimation risk moreover brown 4 examined optimal portfolio choice under uncertainty for various portfolio selection procedures the diffuse bayes rule the markowitz certainty equivalent ce rule the aggregation ce rule and the equal weight rule 1 and found that the diffuse bayes rule uniformly dominates the markowitz ce rule in repeated samples for the quadratic utility case as the sample size increases the bayes rule becomes superior to the aggregation ce and the equal weight rules in addition the result holds even where the probability distribution of returns is seriously misspecified thus brown s 4 study has clearly indicated that without taking estimation risk into account portfolio selection rules other than the bayes rule can lead investors to select suboptimal portfolios this paper shows by using the single index model for the return generating process that the simple decision rules for optimal portfolio selection derived by elton gruber and padberg 7 are not identical under the bayesian and the traditional methods of analysis 2 moreover in the case where short sales are not

the effect of marginal tax rates on taxable income a panel study of the 1986 tax reform act this paper uses a treasury department panel of more than 4 000 taxpayers to estimate the sensitivity of taxable income to changes in tax rates on the basis of a comparison of the tax returns of the same individual taxpayers before and after the 1986 tax reform the analysis emphasizes that the response of taxable income involves much more than a change in the traditional measures of labor supply the evidence shows an elasticity of taxable income with respect to the marginal net of tax rate that is at least one and could be substantially higher the implications for recent tax rate changes are discussed

institutional ownership differential predisclosure precision and trading volume at announcement dates abstract this study examines the relation between ownership structure as revealed by the percentage of outstanding shares held by institutional investors and trading volume at earnings announcement dates we find that volume response as a function of institutional ownership is quadratic with the quadratic curve that reaches a maximum at around 50 institutional ownership when risk tolerances are identical across investor types such a relation is consistent with kim and verrecchia s 1991a proposition that trading volume response to public announcements increases with the level of cross investor variation in precision of private predisclosure information

family background and income during the rise of the welfare state brother correlations in income for swedish men born 1932 1968 we investigate if the association between family background and income in sweden has changed for men born between 1932 and 1968 our main finding is that the share of the variance in long run income that is attributable to family background the so called brother correlation in income has fallen by some 17 from 0 49 for the cohorts of brothers born in the early 1930s to below 0 32 for the cohorts born around 1950 from then on the correlations have inched back up to around 0 37 we report suggestive evidence that the decline is driven by changes in education

the evolution of top incomes in an egalitarian society sweden 1903 2004 this study presents new homogenous series of top income shares in sweden over the period 1903 2004 we find that starting from levels of inequality approximately equal to those in other western countries at the time the income share of the swedish top decile drops sharply over the first eighty years of the twentieth century most of the decrease takes place before the expansion of the welfare state and by 1950 swedish top income shares were already lower than in other countries the fall is almost entirely due to a dramatic drop in the top percentile explained mostly by decreases in capital income while the lower half of the top decile consisting mainly of wage earners experiences virtually no change over this period in the past decades top income shares evolve very differently depending on whether capital gains are included or not when included sweden s experience resembles that in the u s and the u k with sharp increases in top incomes excluding capital gains sweden looks more like the continental european countries where top income shares have remained relatively constant a possible interpretation of our results is that sweden over the past 20 years has become a country where it is more important to make the right financial investments than to earn a lot to become rich

eurosclerosis and the sclerosis of objectivity on the role of values among economic policy experts schumpeter once observed that frequently economists not content with their scientific task yield to the call of public duty and to their desire to serve their country and their age by acting as policy experts and policy advocates schumpeter i949 p 346 this raises the issue discussed by gunnar myrdal i958 p 4 of whether social scientists can be practical and at the same time objective what is the relation between wanting to understand and wanting to change society how can the search for true knowledge be combined with moral and political valuations myrdal s questions point to serious but rarely discussed issues of objectivity and values when economists and other social scientists become involved in the making of public policy often in areas of conflict between major interest groups in western societies see also myrdal i 929 i 958 blaug i 992 ch 5 1 in everyday life the roles of the policy expert and the policy advocate tend to merge this mixing can be understood in terms of sen s distinction between b sic values supposed to apply under all conceivable circumstances and nonbasic values expected to hold only under specified factual circumstances sen i970 p 59 policymaking is typically concerned with non basic values economists can change the goals and choices of policymakers by changing their views of what the facts are by acting as policy advisors many brilliant economists have undoubtedly done excellent service to their countries and their times in this context names such as that of john maynard keynes come to many people s mind however it has also been noted that economic policy advisers frequently rely on anecdotal evidence and misleading statistics stigler i965 rivlin i986 krugman i994 like bad weather this situation has typically been accepted as a necessary evil from the point of view of scientific progress as well as the democratic process however the intellectual responsibility of academic policy experts must be increased with only the threat of losing intellectual credibility as a potential sanction from time to time they should therefore be required to

empirical estimates of beta when investors face estimation risk we examine empirical implications of models of differential information that formalize the following intuition securities for which there is relatively little information are perceived as relatively more risky because of the greater uncertainty surrounding the exact parameters of their return distributions the implication that beta risk for low information firms should decline as information increases is confirmed with several data sets we find such a decline over the first geveral periods subsequent to initial public offerings and initial listings there is also an abrupt risk decline at the first annual earnings announcement this paper examines several empirical implications of security return models involving differential information these models formalize the following intuition securities for which there is relatively little information are perceived as relatively more risky because of the greater uncertainty surrounding the exact parameters of their return distributions the research relates to two streams of literature the first revolves around the new issues and new listings market it begins with ibbotson 1975 and includes for example ritter 1984 beatty and ritter 1986 mcconnell and sanger 1987 and muscarella and vetsuypens 1989 the second is the literature dealing with the effects of differential information on the risk assessment of low information firms this second literature is exemplified by the work of klein and bawa 1976 1977 and barry and brown 1984 1985 in our examination we focus on how increased risk associated with low information firms henceforth called estimation risk manifests itself in observed return data we explore how observed security returns to low information firms appear to researchers in relation to how they appear ex ante to investors who base their predictive distribution of security returns on incomplete information about the parameters of the return generating process we also examine data on new listings and new issues to exemplify some of the relationships the data support the most obvious and direct implication of the differential information model that the expected systematic risk of low information firms decreases as time passes and information increases our evidence as in ibbotson that risk declines with seasoning rejects a restrictive null hypothesis that information risk is diversifiable and the under

model unvertainty political learning and institutions a broader view on mancur olson s theory of institutional sclerosis in his rise and decline of nations mancur olson argues that politically stable countries suffer from declining growth rates caused by the growing influence of distributional coalitions that accumulate over time the empirical literature supports the notion of a negative relationship between a country s duration of political stability and its growth rates but finds only weak support for a negative influence of distributional coalitions on growth this paper sketches a simple model of party competition under model uncertainty which may explain this mixed empirical picture it shows that politically stable democracies are less well equipped to adjust to shifts in their economic environment than democracies with a shorter history of political stability in a further step the paper relates the major theme of this theory and olson s theory to the more recent literature on institutions and growth directions for further research are discussed

a role model for the conduct of fiscal policy experiences from sweden abstract sweden was hit by a severe macroeconomic crisis in the early 1990s gdp fell for three consecutive years in 1991 1993 unemployment increased by 9 percentage points banks had to be nationalized and public budget deficits exceeded 10 percent of gdp the recovery was however quick gdp growth was around four percent in 1994 1995 and budget deficits had been eliminated by 1998 growth remained high in the subsequent decade and the government debt ratio was reduced by almost 50 percent of gdp this paper describes and analyzes the swedish crisis and the policy measures implemented in response to the crisis policy measures include abandoning the fixed exchange rate fiscal austerity a new stricter fiscal framework and several structural reforms in the 1990s these policies were appropriate for handling the swedish crisis but the swedish experiences have limited applicability for the current debt crisis in particular because currency depreciation in combination with strong growth on export markets was a key ingredient in the swedish recovery implementing fiscal austerity would have been more complicated absent this export led growth moreover the new fiscal framework has most likely contributed to strengthening public finances but i demonstrate that budget surpluses and high gdp growth only explain around a third of the reduction in the public debt ratio after 1997

the evolution of individual male earnings in great britain 1975 95 i study the dynamic structure of male wages in great britain using the new earnings survey panel from 1975 95 computing auto covariances of individual wages by cohort i find evidence of a permanent component of earnings that increases over the life cycle and a highly persistent serially correlated transitory component in addition the estimated variances of both these components have risen over this period each explaining about half the rise in inequality using individual s occupation at age 22 i split the sample into four skill groups i find some differences across these groups with the rise in the permanent variance most important for the manual groups

cumulative effects of labor market distortions in a developing country abstract this paper considers a small open economy with an input output industrial structure that creates vertical linkages and multiple equilibria an imperfect labor market is introduced by assuming unionized labor it is shown that a deregulation of the labor market may trigger a large discontinuous expansion of industrial output as reduced wage costs start a circular cumulative process in which expansions of the up and downstream industries promote each other centralization of collective bargaining may however also be conducive to industrialization

economic growth and welfare state a case study of sweden in this article we analyse the relation between the dynamics of economic growth and the welfare state using the swedish experience as a case study we defend three theses concerning the swedish experience that the deep economic crisis of 1990 93 constituted the definite breaking point for the accumulation pattern in force since the 1950s and in crisis since the mid 1970s that the new accumulation pattern eroded the long standing symbiotic relationships between economic growth and the welfare state and that the welfare state has suffered retrenchments and qualitative changes of great importance which can be fundamentally explained by the transformations in the accumulation pattern we conclude that the changes introduced in sweden have continued to subordinate the welfare state s main goals giving priority to the new accumulation pattern

using jump diffusion return models to measure differential information by firm size portfolios of stocks issued by small firms are well known to earn rates of return in excess of those commensurate with their market sensitivities one common explanation for this phenomenon is that small firm stocks are riskier than large firm stocks because less information is available about the former than about the latter a necessary condition for such an explanation to be valid is that the information effect not be eliminated by combining the individual stocks into portfolios this paper uses jump diffusion return models to gauge the impact of information by firm size the results show that portfolios of small firm stocks are no more prone to information surprises than are portfolios of large firm stocks however portfolios of small firm stocks are found to react more severely than portfolios of large firm stocks when surprises do occur

the swedish experiment the deterioration of the economic performance in sweden from about 1970 was to some extent the result of a number of exogenous shocks and unnecessary policy mistakes it was however also related to basic changes in the economic and social system in sweden in the late 1960s and early 1970 when government spending taxes and regulations started to expand dramatically it is also argued in the paper that problematic political economic and social mechanisms had become embedded in the long term dynamics of the system itself these various experiences are the background for recent reforms and retreats of the swedish experiment

differential information and security market equilibrium we propose a simple model of equilibrium asset pricing in which there are differences in the amounts of information available for developing inferences about the returns parame ters of alternative securities in contrast with earlier work we show that parameter uncer tainty or estimation risk can have an effect upon market equilibrium under reasonable conditions securities for which there is relatively little information are shown to have relatively higher systematic risk when that risk is properly measured ceteris paribus the initially very limited model is shown to be robust with respect to relaxation of a number of its principal assumptions we provide theoretical support for the empirical examination of at least three proxies for relative information period of listing number of security returns observations available and divergence of analyst opinion

what happens when you tax the rich evidence from executive compensation this paper examines the responsiveness of taxable income to changes in marginal tax rates using detailed compensation data on several thousand corporate executives from 1991 to 1995 the data confirm that the higher marginal rates of 1993 led to a significant decline in taxable income indeed this small group of executives may account for as much as 20 percent of the aggregate change in wage and salary income for approximately the one million richest taxpayers over this time period one person alone can account for more than 2 percent the decline however is almost entirely a short run shift in the timing of compensation rather than a permanent reduction in taxable income the short run elasticity of taxable income with respect to the net of tax share exceeds one in this sample but the elasticity after one year is at most 0 4 and probably closer to zero breaking out the tax responsiveness of different types of compensation shows that the large short run responses come almost entirely from a large inc

changes in the rate of return to education in sweden 1968 1991 this paper estimates changes in the rate of return to education in sweden between 1968 and 1991 both the quantity years of schooling completed and quality highest qualification obtained dimensions of education are considered adopting a human capital approach the rate of return is measured in terms of differences in wage rates associated with differences in education both quadratic wage and cubic spline wage functions are estimated the data used are from the 1968 1981 and 1991 swedish level of living surveys

understanding swedish social democracy victims of success the economic policies of swedish social democrats were not the product of one centralized authority but rather a series of initiatives influenced by many political actors and inspired by egalitarian preferences we focus on three policy areas first the welfare state is a central achievement of social democracy although its expansion is over it has cemented social democracy s position in power and is still popular among the electorate second the labour market model is in crisis the centralized rehn meidner model is not working coordination of wage bargaining has turned out to be difficult and the trade unions radical politics of the 1970s alienated swedish employers from social concertation finally macroeconomic management has had to struggle with inflationary pressures and the overheating of the late 1980s and the subsequent deflationary shock led to a sharp increase in unemployment in the 1990s many of these problems are related to social democracy s internal strains copyright 1998 by oxford university press

the covariance structure of earnings in great britain 1991 1999 i analyse the dynamic structure of earnings in great britain for the period 1991 99 by decomposing the earnings covariance structure into its permanent and transitory components according to the british household panel study data earnings inequality of male full time employees increases over the 1990s however earnings mobility may have also increased that is for this period earnings persistence falls this evidence is at odds with previous literature on earnings dynamics both for britain and other oecd countries moreover human capital and job related characteristics account for nearly all persistent earnings differences and the transitory component is highly persistent

earnings dynamics and inequality among canadian men 1976 1992 evidence from longitudinal income tax records using an extraordinary database drawn from longitudinal income tax records we decompose canada s growth in earnings inequality into its persistent and transitory components we find that the growth in earnings inequality reflects both an increase in long run inequality and an increase in earnings instability the canadian data strongly reject several restrictions commonly imposed in the u s literature and they also suggest that imposing these evidently false restrictions may lead to distorted inferences about earnings dynamics and inequality trends

the dynamics of government abstract we model income redistribution with dynamic distortions as determined by rational voting without commitment among individuals of different types and income realizations we find that redistribution is too persistent relative to that chosen by a planner with commitment the difference is larger the lower is the political influence of young agents the lower is the altruistic concern for future generations and the lower is risk aversion furthermore there tends to be too much redistribution in the political equilibrium finally smooth preference aggregation as under probabilistic voting produces less persistence and does not admit multiple equilibria which occur under majority voting aggregation

did policy activism work abstract how macroeconomic policy activism influences business cycles remains a major unresolved question this paper compares the degree of cyclical stability in industrialized countries over three periods 1870 1913 1922 1937 and 1950 1979 two of which were little affected by demand management while the third saw a large degree of policy involvement the evidence shows that the 1950 1979 years were unprecedently stable neither problems of data reliability nor the influence of the world cycle nor the smaller role of agriculture appear to be responsible for this the major reason seems to be the greater influence of government which operated via automatic and discretionary policies and by changing expectations

microenterprise lending to female entrepreneurs sacrificing economic growth for poverty alleviation abstract this research compares the performance of female and male entrepreneurs in a microenterprise credit program in guatemala previous research and field practice has suggested that targeting credit at female borrowers allows for greater increases in household welfare but that male entrepreneurs may more aggressively expand enterprises when given access to credit in this paper we develop a model that shows that increases in value of home time during childbearing years for women may substantially account for gender differences in responses to credit access empirical results from guatemalan survey data yield estimations consistent with the predictions from our model

rising earnings inequality in sweden the role of composition and prices the rise in cross sectional earnings inequality in sweden between 1990 and 2002 is decomposed into changes in market prices of observable characteristics changes in the composition of the labor force across demographic groups and industries and changes in unobservables the swedish experience is then compared with that in the united states in both countries the rise in earnings inequality is a consequence of rising upper tail dispersion contrary to the u s experience where the rise is largely driven by changing market prices of observables and increased residual dispersion shifts in the swedish labor force composition have contributed positively to the rise in the p90 p50 gap the rise in the swedish p99 p90 gap however is entirely accounted for by changes in prices and residual dispersion

public sector employment and the skill premium sweden versus the united states 1970 2012 swedish census data and tax records reveal an astonishing decline in the aggregate skill premium of 30 percent between 1970 and 1990 with only a modest recovery in the next couple of decades in contrast the us skill premium rose by around 24 percent over those four decades a theory that equalizes wages with marginal products can rationalize these disparate outcomes when we replace commonly used measures of total labor supplies by private sector employment the dramatic decline in the skill premium in sweden is the result of an expanding public sector that has disproportionately hired unskilled labor

what determines success examining the human financial and social capital of jamaican microentrepreneurs abstract this research examines the performance of 215 informal microenterprises in jamaica studying the influence of human capital social capital and financial capital of the owners on their business profitability understanding the importance of particular relationships that result in successful micro businesses is important for a number of reasons first among many developing countries the growth of microenterprise provides the most visibly vibrant and growing economic activity although considerable effort and resources are being directed toward microenterprise promotion schemes empirical research on the subject is quite limited second economies in developing countries mirror many of the social and institutional problems existent in urban economically disadvantaged areas of the united states and other developed countries for these areas microenterprise may be an essential component of urban renewal and community development this study helps in identifying important characteristics of social and individual attributes that may be relevant to those attempting to strengthen this subsector finally this study seeks to provide insight into a dimension of microbusiness research for which there are limited data specifically the role that social capital plays among practicing entrepreneurs and owners this research found that different structural environments even within a singular and small economy may considerably alter the rates of return to human social and financial capital as a result the analysis of enterprises includes segmentation according to both the usage or not of employees and the sophistication of the technologies used several factors were determined to enhance the profitability of the businesses in all categories vocational training for example demonstrated consistently strong and positive effects mother s high occupational status a proxy for socioeconomic status and years of experience in the business were also consistently positive and strongly associated with increasing profits although additional starting capital played an important role for both the businesses with and without employees increasing amounts failed to differentiate the success of those firms that were already operating in the higher technological tier obtaining a small business loan acted in a similar manner enhancing the profitability of all firms except those segmented into a high technological tier one interpretation of this finding is that the role of technological choice is extremely important and appears to dwarf that of varying amounts of starting capital social capital as operationalized by frequent church attendance and marital status of the owner was found generally to increase the profitability of the business the data demonstrate that social networks play an important role in the success of these businesses and that conditions in the highest tier utilize social capital in a somewhat unique manner

the economic crisis of the 1990s in finland finland s depression a tale of bad luck and bad policies in the 1990s finland underwent a deep depression as its gdp dropped about 14 and unemployment rose from 3 to almost 20 this is a story of bad luck and bad policies bad luck took the form of external shocks the collapse of trade with the former soviet union in 1991 but also sharp cycles in the oecd area however bad luck is far from being the whole story in the absence of bad policies finland would have experienced a recession not a depression bad policies included a poorly designed financial regulation and mistaken reactions to the onset of the crisis of particular interest is the role of financial factors in triggering the crisis and aggravating the effects of bad policies not only were consumption and investment spending hurt by the credit crunch but there is evidence that the private sector s indebtedness has increased structural unemployment which explains why the recovery is proceeding with few job creations a number of general lessons emerge they concern the deregulation of financial markets the policy reaction to massive capital inflows and the role of employment policies seppo honkapohja and erkki koskela

information aggregation in a noisy rational expectations economy abstract this paper analyzes a general equilibrium model of a competitive security market in which traders possess independent pieces of information about the return of a risky asset each trader conditions his estimate of the return both on his own private source of information and price which in equilibrium serves as a noisy aggregator of the total information observed by all traders a closed form characterization of the rational expectations equilibrium is presented a counter example to the existence of fully revealing equilibrium is developed
