analyst forecasting errors additional evidence analyst forecasting errors are approximately as large as dreman and berry 1995 documented and an optimistic bias is evident for all years from 1985 through 1996 in contrast to their findings i show that analyst forecasting errors and bias have decreased over time moreover the optimistic bias in quarterly forecasts was absent for sp 2 firms with comparatively large amounts of market capitalization absolute value of earnings forecast and analyst following and 3 firms in certain industries

the effect of experience on security analyst underreaction abstract we examine if analysts more fully incorporate prior earnings and returns information in their current quarter forecasts as their experience following a firm increases we measure analyst firm specific forecasting experience as the number of prior quarters for which the analyst has issued an earnings forecast for the firm we find that analysts underreact to prior earnings information less as their experience increases suggesting one reason why analysts become more accurate with experience

having your cake and eating it too the before and after tax efficiencies of an extended equity mandate this article shows that extended mandates are especially effective for investors subject to taxes not only is the portfolio more efficiently positioned from a before tax perspective but it also offers significant after tax benefits from both increased loss harvesting and tax arbitrage between tax rates on long and short positions

comparisons and combinations of long and long short strategies market neutral long short strategies get their returns from alphas and short rebates long strategies get their returns from alpha and the market differing return and risk sources complicate their comparison partly because of the strong market referenced focus of conventional performance analysis compelling theoretical advantages of active return per unit of active risk suggest that long short strategies are better able to deliver excess return than are conventional institutional long strategies long short strategies even with tiny positive alphas are seen to improve investors efficient frontiers when added to a traditional t bill long portfolio mix mostly because their risk sources are uncorrelated surprisingly the improvement occurs even if long short strategies are sharpe ratio inferior to long strategies these results provide theoretical support for including long short strategies in most investors mix of assets

the efficiency gains of long short investing long short strategies have generated controversy and institutional interest for more than 10 years we analyzed the efficiency gains of long short investing where we defined efficiency as the information ratio of the implemented strategy the optimal portfolio relative to the intrinsic information ratio of the alphas the efficiency advantage of long short investing arises from the loosening of the surprisingly important long only constraint long short and long only managers need to understand the impact of this significant constraint long short implementations offer the most improvement over long only implementations when the universe of assets is large asset volatility is low and the strategy has high active risk the long only constraint induces biases particularly toward small stocks limits the manager s ability to act on upside information by not allowing short positions that could finance long positions and reduces the efficiency of traditional high risk long only strategies relative t

using elasticities to derive optimal income tax rates this paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates a simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income distribution in the general non linear income tax problem this method using elasticities shows precisely how the different economic effects come into play and which are the key relevant parameters in the optimal income tax formulas of mirrlees the optimal non linear tax rate formulas are expressed in terms of elasticities and the shape of the income distribution these formulas are implemented numerically using empirical earning distributions and a range of realistic elasticity parameters

whisper forecasts of quarterly earnings per share abstract we compare first call analyst forecasts of earnings to unofficial forecasts commonly referred to as whispers our analysis indicates that whispers are more accurate proxies for market expectations of earnings than are first call forecasts consistent with the claim in the professional press that whispers are increasingly becoming the true market expectation of earnings further trading strategies based on the relation between whisper and first call forecasts earn abnormal returns this suggests that whispers contain information not contained in first call forecasts and that at least part of this information is impounded in price prior to the earnings release

communism federalism and ethnic minorities explaining party competition patterns in eastern europe scholarship on east european politics expects that party competition in the region is determined by various communist legacies juxtaposing state centric authoritarianism to a liberal market economy recent empirical evidence however uncovers significant variance of party competition patterns across east european countries to explain this variance this article argues that an interaction between communist institutional framework and partisan responses to ethnic minorities determines party competition structure in the region while experience with communist federalism determines partisan affinities with ethnic minorities tolerance or support for ethnic minorities leads the political actors associated with those minorities to general socially liberal positions consequently and contrary to received knowledge ethnic politics influence the ideological content of party competition and structure party systems in eastern europe

leverage aversion and portfolio optimality portfolio volatility is the only source of risk in mean variance optimality but it fails to capture all the risks faced by leveraged portfolios these risks include the possibility of margin calls and forced liquidations at adverse prices and losses beyond the capital invested to recognize these risks the authors incorporated leverage aversion into the optimization process and examined the effects of volatility and leverage aversion on optimal long short portfolios

evaluating the impact of inequality constraints and parameter uncertainty on optimal portfolio choice we present new analytical results for the impact of portfolio weight constraints on an investor s optimal portfolio when parameter uncertainty is taken into account while it is well known that parameter uncertainty and imposing weight constraints results in reduced certainty equivalent returns in the general case there are no analytical results in a special case commonly used in the funds management literature we derive analytical expression for the certainty equivalent loss that does not depend on the risk aversion parameter we illustrate our theoretical results using hedge fund data from the perspective of a fund of fund manager our contribution is to formalize the framework to investigate this problem as well as providing tractable analytical solutions that can be implemented using either simulated or asset manager returns

growth and chronic poverty evidence from rural communities in ethiopia abstract what keeps some people persistently poor even in the context of relative high growth in this article we explore this question using a 15 year longitudinal data set from ethiopia we compare the findings of an empirical growth model with those derived from a model of the determinants of chronic poverty we ask whether the chronically poor are simply not benefiting in the same way from the same factors that allowed others to escape poverty or whether there are latent factors that leave them behind we find that this chronic poverty is associated with several initial characteristics lack of physical assets education and remoteness in terms of distance to towns or poor roads the chronically poor appear to benefit from some of the drivers of growth such as better roads or extension services in much the same way that the non chronically poor benefit however they appear to have lower growth in this period related to time invariant characteristics and this suggests that they face a conside

loss function assumptions in rational expectations tests on financial analysts earnings forecasts abstract prior research concludes that financial analysts do not process public information efficiently in generating their earnings forecasts the ordinary least squares ols regression based tests used in prior studies assume implicitly that analysts face a quadratic loss function in contrast we argue that analysts likely face a linear loss function and hence try to minimize their absolute forecast errors we conduct and compare rational expectations tests using these two alternative loss functions we reproduce most prior findings of forecast inefficiency with ols regressions but find virtually no evidence of forecast inefficiency with least absolute deviation regressions where we explicitly assume a linear loss function

the performance and competitive effects of school autonomy this paper studies a recent british reform that allowed public high schools to opt out of local authority control and become autonomous schools funded directly by the central government schools seeking autonomy had only to propose and win a majority vote among current parents almost one in three high schools voted on autonomy between 1988 and 1997 and using a version of the regression discontinuity design i find large achievement gains at schools in which the vote barely won compared to schools in which it barely lost despite other reforms that ensured that the british education system was by international standards highly competitive a comparison of schools in the geographic neighborhoods of narrow vote winners and narrow vote losers suggests that these gains did not spill over

on the optimal income taxation some further numerical results abstract using numerical calculations we show in the optimal income tax model that a realistic value for the elasticity of substitution between consumption and leisure 0 5 leads to conclusions different from some of those drawn by mirrlees 1971 and atkinson 1973 the marginal tax rates are not so low and the shape of the tax schedule is for a great majority of the population substantially nonlinear a new feature in our calculations is that both results come out without going to maximin as done by atkinson 1973 we study in special cases the locality of the zero limit of the marginal tax rate at the upper end of the ability distribution and we achieve a very definite conclusion this result is really very local we also present an interesting approximation result concerning the relationship between the level of the government revenue and the marginal tax rate for individuals with high ability an important methodological remark analogous to sen s critique on the ethical measures of inequality is made on the interpretation of optimal income tax calculations

inequality growth and democracy the analysis of the relationship between inequality and economic growth in distinct politi coeconomic environments has been one of the central preoccupations of the extensive theoretical and empirical work on growth in the last decade the authors argue that the empirical evidence available to date strongly indicates the relevance of this work for understanding the elusive causal connection between economic development and democracy the state of the literature suggests considerable sophistication in conceptualizing the direct economic effects of inequality and contains critical insights into politically unconstrained policy making aimed at the alleviation of their negative economic impact however the political feasibility of the recommended policy measures and the politically mediated effects of inequality and redistributive policy on growth and on the strength and stability of democratic regimes are understood less well the authors discuss the critical factors influencing these effects and sketch several approaches to creating a comprehensive politicoeconomic account of the interaction between inequality redistributive policy making and political regimes

inequality and democracy why inequality harms consolidation but does not affect democratization under what conditions do democracies emerge and consolidate recent theories suggest that inequality is among the leading determinants of both democratization and consolidation by contrast this article argues that inequality harms consolidation but has no net effect on democratization the author shows that the existing theories that link inequality to democratization suffer from serious limitations 1 they are useful only for understanding transitions from below and thus do not apply to many other transitions that is those from above 2 even for democratization from below their predictions are unlikely to hold since inequality actually has two opposite effects and 3 they ignore collective action problems which reduces their explanatory power however these objections do not affect the relationship between inequality and consolidation in particular while inequality has two opposite effects on the probability of transition to democracy it unambiguously increases the probability of transition away from democracy this article conducts the most comprehensive empirical test to date of the relationship between inequality and democracy it finds no support for the main democratization theories contrary to what they predict estimation suggests neither a monotonic negative nor an inverted u shaped relationship yet inequality increases the probability of backsliding from democracy to dictatorship

decentralization and access to social services in colombia decentralization is meant to improve access to public services but relatively few studies examine this question empirically we explore the effects of decentralization on access to health and education in colombia using an original database covering over 95 of colombian municipalities we show that decentralization improved enrollment rates in public schools and access of the poor to public health services in both sectors improving access was driven by the financial contributions of local governments small increases in own shares of spending led to surprisingly large increases in the access of the poor in both sectors our theoretical model implies that where local information dominates productive efficiency elected local governments will provide services better tailored to local needs decentralizing such services should increase their use by the public together theory and empirics imply that decentralization made the colombian state more accountable it provided local officials with the information and incentives they need to allocate resources in a manner responsive to voters needs and improve the impact of public expenditures

economic policy distribution and poverty the nature of disagreements abstract the last 20 years have seen growing areas of agreement on poverty reduction strategies but disagreements on economic policy distribution and poverty seem to have intensified this paper tries to identify the underlying nature of these disagreements related to differences in perspective and framework between finance ministry and civil society tendencies it is argued that the deep divisions one sees can be located in differences in the level of aggregation adopted the time horizon considered and assumptions made on market structure and power mutual understanding could be advanced by further exploration of these differences and the adoption by both sides of the approach of dialogue rather than negotiation

fundamentals of efficient factor investing corrected may 2017 combining long only constrained factor subportfolios is generally not a mean variance efficient way to capture expected factor returns for example a combination of four fully invested factor subportfolios low beta small size value and momentum captures less than half e g 40 of the potential improvement over the market portfolio s sharpe ratio in contrast a long only portfolio of individual securities using the same risk model and return forecasts captures most e g 80 of the potential improvement we adapt traditional portfolio theory to more recently popularized factor based investing and simulate optimal combinations of factor and security portfolios using the largest 1 000 common stocks in the us equity market from 1968 to 2015

60 years of portfolio optimization practical challenges and current trends abstract the concepts of portfolio optimization and diversification have been instrumental in the development and understanding of financial markets and financial decision making in light of the 60 year anniversary of harry markowitz s paper portfolio selection we review some of the approaches developed to address the challenges encountered when using portfolio optimization in practice including the inclusion of transaction costs portfolio management constraints and the sensitivity to the estimates of expected returns and covariances in addition we selectively highlight some of the new trends and developments in the area such as diversification methods risk parity portfolios the mixing of different sources of alpha and practical multi period portfolio optimization

school decentralization helping the good get better but leaving the poor behind abstract the decentralization of public services is a major feature of institutional innovation the main argument in support of decentralization is that it brings decisions closer to the people thereby alleviating information asymmetries and improving accountability however decentralization can also degrade service provision in poor communities that lack the ability to voice and defend their preferences in this paper we analyze the average and distributional effects of school decentralization on educational quality in argentina we find that decentralization had an overall positive impact on student test scores the decentralization gains however did not reach the poor thus although bringing decisions closer to the people may help the good get better the already disadvantaged may not receive these benefits

the rewards to meeting or beating earnings expectations abstract this paper finds that firms that meet or beat current analysts earnings expectations mbe enjoy a higher return over the quarter than firms with similar quarterly earnings forecast errors that fail to meet these expectations further such a premium to mbe although somewhat smaller exists in the cases where mbe is likely to have been achieved through earnings or expectations management the findings also indicate that the premium to mbe is a leading indicator of future performance this premium and its predictive ability are only marginally affected by whether the mbe is genuine or the result of earnings or expectations management

aid policies and growth the authors of this paper use a new database on foreign aid to examine the relationships among foreign aid economic policies and growth of per capita gdp in panel growth regressions for 56 developing countries and 6 four year periods 1970 93 they find that the policies that have a great effect on growth are those related to fiscal surplus inflation and trade openness they construct an index for those three policies and have that index interact with foreign aid they have instruments for both aid and aid interacting with policies they find that aid has a positive impact on growth in developing countries with good fiscal monetary and trade policies in the presence of poor policies aid has no positive effect on growth this result is robust in a variety of specifications which include or exclude middle income countries include or exclude outliers and treat policies as exogenous or endogenous they examine the determinants of policy and find no evidence that aid has systematically affected policies either for good or for ill they estimate an aid allocation equation and show that any tendency for aid to reward good policies has been overwhelmed by donors pursuit of their own strategic interests in a counterfactual they reallocate aid reduce the role of donor interests and increasing the importance of policy such a reallocation would have a large positive effect on developing countries growth rates

the myth of the absolute return investor the notion of absolute return investing is spreading like wildfire many people believe that superior returns can be achieved by managers with strong views and little regard for benchmarks this article attempts to define absolute return investing and figure out whether it exists the conclusion is that all investment returns consist of a beta part representing the correlation of the active portfolio with one or more market benchmarks or normal portfolios and an active alpha part thus all investing is relative return investing in which active returns are earned relative to an appropriate benchmark or mix of benchmarks

growth inequality and poverty looking beyond averages the evidence is compelling that the poor in developing countries do typically share in the gains from rising aggregate affluence and in the losses from aggregate contraction but how much do poor people share in growth do they gain more in some settings than others do some gain while others lose does pro poor growth mean more or less aggregate growth recent theories and evidence suggest some answers but deeper microeconomic empirical work is needed on growth and distributed change only then will we have a firm basis for identifying the specific policies and programs needed to complement and possibly modify growth oriented policies

intergenerational persistence of earnings the role of early and college education recent empirical evidence from the united states indicates a high degree of persistence in earnings across generations designing effective public policies to increase social mobility requires identifying and measuring the major sources of persistence and inequality in earnings we provide a quantitative model of intergenerational human capital transmission that focuses on three sources innate ability early education and college education we find that approximately one half of the intergenerational correlation in earnings is accounted for by parental investment in education in particular early education we show that these results have important implications for education policy

the big push deja vu a review of jeffrey sachs s the end of poverty economic possibilities for our time jeffrey sachs s new book the end of poverty economic possibilities for our time penguin press new york 2005 advocates a big push featuring large increases in aid to finance a package of complementary investments in order to end world poverty these recommendations are remarkably similar to those first made in the 1950s and 1960s in development economics today as then the big push recommendation overlooks the unsolvable information and incentive problems facing any large scale planning exercise a more promising approach would be to design incentives for aid agents to implement interventions piecemeal whenever they deliver large benefits for the poor relative to costs

balancing rural poverty reduction and citizen participation the contradictions of uganda s decentralization program abstract uganda s ambitious decentralization program is analyzed in terms of a dual mode system of local governance under a technocratic mode conditional funding from the center is earmarked for particular programs but with little local participation in contrast the patronage mode is an elaborate system for local bottom up planning but with limited resources which are largely consumed in administrative costs and political emoluments along with the spoils of a committee system controlling contracts and appointments these resources provide the means for building political alliances and loyalty in the absence of a culture of transparency and civic engagement to assure downward accountability it remains to be seen whether decentralization can promote both efficient service delivery and local empowerment simultaneously

fiscal decentralization and natural hazard risks at least to some extent due to pressure from international donors many countries have become more fiscally decentralized the underlying premise being that greater decentralization might improve the provision of local public goods and services we test this proposition by determining whether relatively more decentralized countries fare better when natural disasters strike in terms of its effects on the population overall we find evidence supporting our maintained hypothesis though the effect appears much more robust in developing countries

consensus expectations and international equity returns numerous studies of u s markets have shown that stock selection models have been able to isolate securities that earn returns above those predicted by a simple market model models examining the relation between analyst expectations and returns have been particularly useful unexpected earnings changes in analysts earnings per share forecasts the number of analysts revising their forecasts all these measures have been found to be useful in predicting abnormal returns in u s equity markets at least two of these measures changes in analysts eps forecasts and the number of analysts changing their forecasts are also related to abnormal returns in several international markets

portfolio frontiers with restrictions to tracking error volatility and value at risk abstract asset managers are often given the task of restricting their activity by keeping both the value at risk var and the tracking error volatility tev under control however these constraints may be impossible to satisfy simultaneously because var is independent of the benchmark portfolio the management of these restrictions is likely to affect portfolio performance and produces a wide variety of scenarios in the risk return space the aim of this paper is to analyse various interactions between portfolio frontiers when risk managers impose joint restrictions upon tev and var specifically we provide analytical solutions for all the intersections and we propose simple numerical methods when such solutions are not available finally we introduce a new portfolio frontier

how variation in signal quality affects performance the information coefficient ic the correlation between forecasted and realized return is a popular measure of signal quality as shown in this article variation in ic is an important source of active risk and ic variation has an effect on optimal portfolio structure contrary to popular belief the ability to take short positions in equity portfolios does not necessarily lead to superior performance managers who can maintain a stable ic over time will benefit from short extensions but managers who have an unstable ic may see their performance deteriorate from increased short positions

tax policy and human capital formation missing from recent discussions of tax reform is any systematic analysis of the effects of various tax proposals on skill formation this gap in the literature in empirical public finance is due to the absence of any empirically based general equilibrium models with both human capital formation and physical capital formation that are consistent with observations on modern labor markets this paper is a progress report on our ongoing research on formulating and estimating dynamic general equilibrium models with endogenous heterogeneous human capital accumulation our model explains many features of rising wage inequality in the u s economy james heckman lance lochner and christopher taber 1998 in this paper we use our model to study the impacts on skill formation of proposals to switch from progressive taxes to flat income and consumption taxes for the sake of brevity we focus on steady states in this paper although we study both transitions and steady states in our research this abstract was borrowed from another version of this item

blending top down federalism with bottom up engagement to reduce inequality in ethiopia donors increasingly fund interventions to counteract inequality in developing countries where they fear it can foment instability and undermine nation building efforts to succeed aid relies on the principle of upward accountability to donors but federalism shifts the accountability of subnational officials downward to regional and local voters what happens when aid agencies fund anti inequality programs in federal countries does federalism undermine aid does aid undermine federalism or can the political and fiscal relations that define a federal system resolve the contradiction internally this study explores this paradox via the promotion of basic services program in ethiopia the largest donor financed investment program in the world using an original panel database comprising the universe of ethiopian woredas districts the study finds that horizontal geographic inequality decreased substantially donor financed block grants to woredas increased the availability of primary education and health care services in the bottom 20 percent of woredas weaker evidence from household surveys suggests that vertical inequality across wealth groups within woredas also declined implying that individuals from the poorest households benefit disproportionately from increasing access to and utilization of such services the evidence suggests that by combining strong upward accountability over public investment with extensive citizen engagement on local issues ethiopia s federal system resolves the instrumental dissonance posed by aid funded programs to combat inequality in a federation

on aid growth and good policies this study provides a critical analysis of the growth regressions in burnside and dollar 2000 first we analyse the relationship between aid and government expenditure in a modified neo classical growth model one of the main results of the analysis is that while good policies spur growths they may at the same time reduce the effectiveness of foreign aid second we show that the econometric results in burnside and dollar emphasising the crucial role of interaction between aid and good policies in the growth process are fragile as they are extremely data dependent finally we demonstrate that the burnside and dollar data lend support to the idea that the association between aid and growth can be approximated by decreasing returns to aid this finding conforms well to regression results in other recent studies

illiquidity position limits and optimal investment for mutual funds we study the optimal trading strategy of mutual funds that face both position limits and differential illiquidity we provide explicit characterization of the optimal trading strategy and conduct an extensive analytical and numerical analysis of the optimal trading strategy we show that the optimal trading boundaries are increasing in both the lower and the upper position limits we find that position limits can affect current trading strategy even when they are not currently binding and other seemingly intuitive trading strategies can be costly we also examine the optimal choice of position limits

individual analyst characteristics and forecast error the purpose of the study reported here was to investigate how characteristics of analysts affect their forecast errors previous research has found positive serial correlation in forecast errors which can be attributed to underreaction to new information especially to bad news the relationship between an analyst s behavior and that analyst s characteristics is not clear however because most previous work was based solely on consensus estimates by using detailed historical data i found a stronger serial correlation among the herd to consensus analysts that is the group with a small average distance between their forecasts and the consensus forecast than among other analysts moreover average distance to consensus itself has a positive serial correlation and it may be attributed to an analyst s personality optimistic or pessimistic i found strong positive serial correlation in the average distance to consensus among the herd to consensus analysts these results show that herd to consensus ana

portfolio constraints and the fundamental law of active management active portfolio management is typically conducted within constraints that do not allow managers to fully exploit their ability to forecast returns constraints on short positions and turnover for example are fairly common and materially restrictive other constraints such as market capitalization and value growth neutrality with respect to the benchmark or economic sector constraints can further restrict an active portfolio s composition we derive ex ante and ex post correlation relationships that facilitate the performance analysis of constrained portfolios the ex ante relationship is a generalized version of a previously developed fundamental law of active management and provides an important strategic perspective on the potential for active management to add value the ex post correlation relationship represents a practical decomposition of performance into the success of the return prediction process and the noise associated with portfolio constraints we verify the accuracy of these relati

right target wrong mechanism agricultural modernization and poverty reduction in uganda summary household consumption surveys suggest that the downward trend in rural poverty indicators recorded in uganda during the 1990s has been reversed since 2000 this paper examines the ugandan government s strategy to reduce rural poverty the plan for modernization of agriculture pma it argues that while there appear few better choices of target for the pma than to improve incomes of the rural poor through increased agricultural productivity emphasis on decentralization as a mechanism for poverty reduction is misplaced in the current political context of uganda the paper considers what alternative mechanisms might better deliver reductions in rural poverty

second generation fiscal federalism the implications of fiscal incentives abstract first generation fiscal federalism fgff studies the performance of decentralized systems under the assumption of benevolent social planners second generation fiscal federalism sgff studies performance based on the fiscal and political incentives facing subnational officials the paper focuses on three aspects of sgff first it considers the design of intergovernmental transfers while fgff emphasizes correcting vertical and horizontal equity sgff emphasizes the importance of fiscal incentives for producing local economic prosperity sgff extends fgff approaches by showing how non linear transfer systems can produce both equalization and high marginal fiscal incentives to produce local economic growth second the paper raises the fiscal incentive approach showing how different tax systems produce different fiscal incentives for political officials to choose policies third the paper discusses the interaction of democracy and fiscal federalism

political connections and social networks in targeted transfer programs evidence from rural ethiopia abstractdespite increasingly large scale social protection programs in africa we have limited evidence on the local political economy of their allocation we investigate community based processes for food aid allocation and the role of political and social networks using the case of ethiopia in the aftermath of a serious drought in 2002 local political authorities are in charge of food transfers in terms of free food aid or food for work programs we find that although targeting is clearly imperfect free food aid is responsive to need as well as targeted to households with less access to support from relatives or friends we also find a strong correlation with political connections households with close associates in official positions have more than a 12 higher probability of obtaining free food than households that are not well connected this effect is large someone without political connections has the same probability of getting food aid as someone more than twice as rich but with these conne

performance attribution and the fundamental law the reported study operationalized the fundamental law of active management in the context of a factor based performance attribution system the system incorporates factor payoffs in the linear regression framework that many portfolio managers and external reviewers use to judge what is being rewarded in the market the study indicates that parameters of the fundamental law can be used to approximate and interpret the results of the regression based performance attribution system the procedure is illustrated by the use of security holdings returns and factor exposure data for two portfolios benchmarked to the s p 500 index for april 1995 to march 2004

global equity fund performance an attribution approach using data on portfolio holdings we examine the performance of 143 global equity funds over 2002 2012 we find that the average global equity manager outperforms the benchmark by 1 2 1 4 a year before fees attribution analysis reveals that the prime source of excess return is selecting stocks that beat their local markets modest contributions come from country selection most notably in emerging markets whereas currency effects are mixed our findings support considering active management in global equity markets at least for institutional accounts that pay annual fees of less than 1

welfare state retrenchment revisited entitlement cuts public sector restructuring and inegalitarian trends in advanced capitalist societies in recent years it has become commonplace for comparativists to emphasize the resilience of welfare states in advanced capitalist societies and the failure of neoliberal efforts to dismantle the welfare state challenging some tenets of the resilience thesis this article seeks to broaden the discussion of welfare state retrenchment the authors argue that a sharp deceleration of social spending has occurred in most oecd countries since 1980 that welfare states have failed to offset the rise of market generated inequality and insecurity and that welfare programs have become less universalistic they stress the distributive and political consequences of market oriented reforms of the public sector

optimal fiscal policy with redistribution i study the optimal taxation oflabor and capital in a dynamic economy subject to government expenditure and technology shocks unlike representative agent ramsey models workers are heterogenous and lump sum taxation is not ruled out i consider two tax scenarios a linear taxation with a lump sum intercept and b nonlinear mirrleesian taxation when taxes are linear i derive a partial equivalence result with ramsey settings that provides a reinterpretation of such analyses i find conditions for perfect tax smoothing oflabor income taxes and zero capital taxation implications that contrast with ramsey are derived for public debt management for the nature of the time inconsistency problem and for the viability of replicating complete markets without state contingent bonds shifts in the distribution of skills provide a novel source for variations in tax rates for the nonlinear tax scenario i show that taxation based on income averages is optimal

aid allocation and poverty reduction the authors derive a poverty efficient allocation of aid and compare it with actual aid allocations they build the poverty efficient allocation in two stages first they use new world bank ratings of 20 different aspects of national policy to establish the current relationship between aid policies and growth onto that they add a mapping from growth to poverty reduction which reflects the level and distribution of income they compare the effects of using headcount and poverty gap measures of poverty they find the actual allocation of aid to be radically different from the poverty efficient allocation in the efficient allocation for a given of poverty aid tapers in with policy reform in the actual allocation aid tapers out with reform in the efficient allocation aid is targeted disproportionately to countries with severe poverty and adequate polices the type of country where 74 percent of the world s poor live in the actual allocation such countries receive a much smaller share of aid 56 percent than their share of the world s poor with the present allocation aid is effective in sustainably lifting about 30 million people a year out of absolute poverty with a poverty efficient allocation this would increase to about 80 million people even with political constraints introduced to keep allocations for india and china constant poverty reduction would increase to about 60 million reallocating aid is politically difficult but it may be considerably less difficult than quadrupling aid budgets which is what the authors estimate would be necessary to achieve the same impact on poverty reduction with existing aid allocations

human capital and earnings distribution dynamics abstract earnings heterogeneity plays a crucial role in modern macroeconomics we document that mean earnings and measures of earnings dispersion and skewness all increase in us data over most of the working life cycle for a typical cohort as the cohort ages we show that i a human capital model can replicate these properties from the right distribution of initial human capital and learning ability ii differences in learning ability are essential to produce an increase in earnings dispersion over the life cycle and iii differences in learning ability account for the bulk of the variation in the present value of earnings across agents these findings emphasize the need to further understand the role and origins of initial conditions

optimal human capital policies abstract we analyze optimal income taxes and optimal schooling subsidies in a dynamic private information economy with observable human capital accumulation we show that under plausible conditions the marginal schooling subsidies are positive and that they are zero at both endpoints of the skill distribution we compute the optimal policies and evaluate their impact over the transition and at the steady state we find that the optimal schooling policies are significantly smaller than the optimal marginal income taxes if optimal schooling policies are introduced jointly with optimal income taxes then their welfare and aggregate effects are small however if income taxes are not set optimally then the optimal schooling policies have significant welfare and aggregate effects

on the strategic behavior of large investors a mean variance portfolio approach abstract one key assumption of markowitz s model is that all traders act as price takers in this paper we extend this mean variance approach in a setting where large investors can move prices instead of having an individual optimization problem we find the investors nash equilibrium and redefine the efficient frontier in this new framework we also develop a simplified application of the general model with two assets and two investors to shed light on the potential strategic behavior of large and atomic investors our findings validate the claim that large investors enhance their portfolio performance in relation to perfect market conditions besides we show under which conditions atomic investors can benefit in relation to the standard setting even if they have not total influence on their eventual performance the two investors two assets setting allows us to quantify performance and do sensitivity analysis regarding investors market power risk tolerance and price elasticity of demand finally for a group of well known etfs we empirically show how price variations change depending on the volume traded we also explain how to set up and use our model with real market data

a note on market neutral portfolio selection abstract long short equity strategies allow investors to benefit potentially from both undervalued and overvalued securities the present study develops a normative portfolio model under the practical conditions that a market neutral strategy entails the offsetting long and short equity holdings are established jointly and without any constraints by the underlying market index while accurately capturing institutional procedures for short selling the model contains the analytical and economic properties as required for a ranking approach to filter out any undesirable securities under consideration in view of its practical features the analysis should be of interest to practitioners for assisting their long short investment decisions
