insecure alliances risk inequality and support for the welfare state popular support for the welfare state varies greatly across nations and policy domains we argue that these variations vital to understanding the politics of the welfare state reflect in part the degree to which economic disadvantage low income and economic insecurity high risk are correlated when the disadvantaged and insecure are mostly one and the same the base of popular support for the welfare state is narrow when the disadvantaged and insecure represent two distinct groups popular support is broader and opinion less polarized we test these predictions both across nations within a single policy area unemployment insurance and across policy domains within a single polity the united states using a new survey results are consistent with our predictions and are robust to myriad controls and specifications when disadvantage and insecurity are more correlated the welfare state is more contested hy do citizens support the welfare state the answer remains as elusive as the question is fundamental we know that patterns of public support vary greatly across nations and domains of social policy we also know that these differences are associated with variations in levels of spending and program generosity brooks and manza 2006a 2006b 2007 kang and powell 2010 svallfors 1997 2004 yet there has only been limited effort to explain why patternsofpublicsupportvary thatis whyaggregatepublic support polarization of opinion and the breadth of opposition to the welfare state differ across societies and social policy areas in this article we develop such a proposition distinguish it from other leading claims and show that it finds strong confirmation not only in cross national analysis but also when examining popular support for different social policies within the united states the proposition is that the structure of support for the welfare state varies with the joint distribution of economic disadvantage low income and economic in

the impacts of government ideology on innovation what are the main implications abstract this study investigates the relationship between government ideology and technical innovativeness of the whole country by using multinational panel data covering 110 countries from 1995 to 2015 and by employing comprehensive indicators for technical innovation i e trademark and patent application in empirical research we utilize the panel generalized method of moment gmm technique to introduce dynamic variables in order to avoid the bias caused by potential endogeneity next we generate three cross items to examine whether the effect of government ideology on technical innovation differs under different circumstances we then change the measurement of government ideology to assure the reliability of our empirical results further investigate whether the changes of political ideology influence technical innovation and carry out a robustness test by dividing the whole sample into two sub samples based on the level of democracy by employing two samples which limited by 3 main coalition parties in government at most such as re elected government and non alternated government in countries overall the empirical results show that a leftist ruling party inhibits the progress of technical innovation whereas a right wing ruling party promotes the appearance of new technology the effect of government ideology on innovation is not similar under some circumstances more evidence is presented by using two dummy variables to represent left wing and right wing

the pricing of options on assets with stochastic volatilities one option pricing problem that has hitherto been unsolved is the pricing of a european call on an asset that has a stochastic volatility this paper examines this problem the option price is determined in series form for the case in which the stochastic volatility is independent of the stock price numerical solutions are also produced for the case in which the volatility is correlated with the stock price it is found that the black scholes price frequently overprices options and that the degree of overpricing increases with the time to maturity one option pricing problem that has hitherto remained unsolved is the pricing of a european call on a stock that has a stochastic volatility from the work of merton 12 garman 6 and cox ingersoll and ross 3 the differential equation that the option must satisfy is known the solution of this differential equation is independent of risk preferences if a the volatility is a traded asset or b the volatility is uncorrelated with aggregate consumption if either of these conditions holds the risk neutral valuation arguments of cox and ross 4 can be used in a straightfoward way this paper produces a solution in series form for the situation in which the stock price is instantaneously uncorrelated with the volatility we do not assume that the volatility is a traded asset also a constant correlation between the instantaneous rate of change of the volatility and the rate of change of aggregate consumption can be accommodated the option price is lower than the blackscholes b s 1 price when the option is close to being at the money and higher when it is deep in or deep out of the money the exercise prices for which overpricing by b s takes place are within about ten percent of the security price this is the range of exercise prices over which most option trading takes place so we may in general expect the b s price to overprice options this effect is exaggerated as the time to maturity increases one of the most surprising implications of this is that if the b s equation is used to determine the implied volatility of a near the money option the longer the time to maturity the lower the implied volatility numerical solutions for the case in which the volatility is correlated with the stock price are also examined the stochastic volatility problem has been examined by merton 13 geske 7 johnson 10 johnson and shanno 11 eisenberg 5 wiggins 16 and

diminished expectations redistributive preferences in truncated welfare states in latin america the relationship between income and support for redistribution is weak and variable despite the region s extreme income inequality this article shows that this condition is rooted in the truncated structure of many latin american welfare states heavy spending on contributory social insurance for formal sector workers flat or regressive subsidies and informal access barriers mean that social spending does far less for the poor in latin america than it does in advanced industrial economies using public opinion data from across latin america and original survey data from colombia the author demonstrates that income is less predictive of attitudes in the countries and social policy areas in which the poor gain less from social expenditures social policy exclusion leads the poor to doubt that they will benefit from redistribution thereby dampening their support for it the article reverses an assumption in political economy models that welfare exclusion unleashes demands for greater redistribution instead truncation reinforces skepticism about social policy helping the poor welfare state reforms to promote social inclusion are essential to strengthen redistributive coalitions

the local structure of the welfare state uneven effects of social spending on poverty within countries research has shown that there is a strong negative relationship between social spending and poverty levels among urban inequality researchers it is often assumed that compared with the usa the welfare state has mitigated social differences explaining lower levels of urban inequality in most european countries however research on the role of the welfare state is often conducted on the national level and is thus unable to draw conclusions on the effects of social spending and redistribution on a lower level failing to take the within country variation into account this study connects welfare state research to urban inequality research by investigating the effects of social spending on poverty in urban and non urban areas we have conducted a cross national multilevel logistic regression analysis using eurostat and european social survey data of 2008 our findings suggest that the effects of social spending are unequally distributed within countries

the material consequences of welfare states benefit generosity and absolute poverty in 16 oecd countries several recent studies have focused attention on the relationship between welfare states and poverty looking primarily at relative poverty and employing concepts of welfare state generosity that are problematic this has made it difficult to evaluate claims that equality has come at the expense of economic growth in this article the authors examine more directly the relationship between welfare state generosity in three social insurance programs unemployment sickness and pensions and poverty levels in advanced industrial democracies in the past quarter of the 20th century the results strongly suggest that more generous entitlements to key social insurance programs are associated not only with lower relative poverty but also with lower absolute poverty this supports the contention that promoting relative economic equality can improve the absolute material well being of the poor however no evidence suggests that relatively more generous unemployment benefits systematically reduce poverty

recovering probability distributions from option prices this article derives underlying asset risk neutral probability distributions of european options on the s p 500 index nonparametric methods are used to choose probabilities that minimize an objective function subject to requiring that the probabilities are consistent with observed option and underlying asset prices alternative optimization specifications produce approximately the same implied distributions a new and fast optimization technique for estimating probability distributions based on maximizing the smoothness of the resulting distribution is proposed since the crash the risk neutral probability of a three four standard deviation decline in the index about 36 percent 46 percent over a year is about 10 100 times more likely than under the assumption of lognormality recently the increasing popularity of derivatives and some highly publicized failures to control risk have led to increased efforts to find reasonable methods to measure the sensitivity of large institutional derivatives portfolios to extreme events merely because such events are rare is not sufficient to ignore them since on the few occasions when they do occur significant amounts of money can change hands potentially wiping out profits accumulated over long prior periods a key assumption behind methods of estimation is the joint probability distribution of constituent underlying asset returns this has long been a concern of financial economists since probability assumptions are critical to much of their research during the last quarter century heretofore probability distributions of stock market returns have typically been estimated from historical time series unfortunately common hypotheses may not capture the probability of extreme events and the events of interest are rare or may not be present in the historical record even though they are clearly possible

budgetary units a weberian approach to consumption1 established consumption theory relies heavily on application of individualistic frames and market models of behavior a framework built around consumption oriented groups would facilitate progress toward a more general theory of consumption this article reintroduces and extends weber s budgetary unit concept to address this gap correcting key problems dogging the consumption literature the budgetary unit concept 1 offers a new framework for theorizing and better accounting for observed consumption patterns 2 reveals how consumption units have organizational logics preferences strengths and vulnerabilities that are consequentially distinct from market logic of production and profit and 3 focuses attention on social processes and features enabling theorization of general social patterns of consumption across diverse contexts this article highlights the explanatory power and broad applicability of weber s budgetary unit approach using the conventionally dissimilar cases of russian organized

paradoxes of social policy welfare transfers relative poverty and redistribution preferences korpi and palme s 1998 classic the paradox of redistribution and strategies of equality claims that universal social policy better reduces poverty than social policies targeted at the poor this article revisits korpi and palme s classic and in the process explores and informs a set of enduring questions about social policy politics and social equality specifically we investigate the relationships between three dimensions of welfare transfers transfer share the average share of household income from welfare transfers low income targeting and universalism and poverty and preferences for redistribution we analyze rich democracies like korpi and palme but we also generalize to a broader sample of developed and developing countries consistent with korpi and palme we show 1 poverty is negatively associated with transfer share and universalism 2 redistribution preferences are negatively associated with low income targeting and 3 universalism is positively associated with transfer share

generalized parameter functions for option pricing we extend the benchmark nonlinear deterministic volatility regression functions of dumas et al 1998 to provide a semi parametric method where an enhancement of the implied parameter values is used in the parametric option pricing models besides volatility skewness and kurtosis of the asset return distribution can also be enhanced empirical results using closing prices of the s p 500 index call options in one day ahead out of sample pricing tests strongly support our method that compares favorably with a model that admits stochastic volatility and random jumps moreover it is found to be superior in various robustness tests our semi parametric approach is an effective remedy to the curse of dimensionality presented in nonparametric estimation and its main advantage is that it delivers theoretically consistent option prices and hedging parameters the economic significance of the approach is tested in terms of hedging where the evaluation and estimation loss functions are aligned

employers and the welfare state the political economic organization of firms and social policy in contemporary capitalist democracies the authors argue that the organization of employers shapes social policy support among firms and in turn affects social policy outcomes specifically the authors argue that the centralization and cohesion of employer groups and economic cooperation across enterprises positively affects social welfare provision empirically the authors assess the impacts of business organization on social welfare effort in 15 developed democracies between the 1970s and 1990s the authors also provide analysis of the impact of employer organization on active labor market policy the authors find that the organization of employers is one of the most important determinants of overall social welfare effort the authors also find that employer organization affects the development of active labor market policies and it influences the degree to which social democratic parties pursue active labor market programs the authors conclude with a discussion of the findings implications for theories of social corporatism and the w

implied volatility functions empirical tests derman and kani 1994 dupire 1994 and rubinstein 1994 hypothesize that asset return volatility is a deterministic function of asset price and time and develop a deterministic volatility function dvf option valuation model that has the potential of fitting the observed cross section of option prices exactly using s p 500 options from june 1988 through december 1993 we examine the predictive and hedging performance of the dvf option valuation model and find it is no better than an ad hoc procedure that merely smooths black scholes 1973 implied volatilities across exercise prices and times to expiration

power resources and employer centered approaches in explanations of welfare states and varieties of capitalism protagonists consenters and antagonists the power resources approach underlining the relevance of socioeconomic class and partisan politics in distributive conflict within capitalist economies is challenged by employer centered approaches claiming employers and cross class alliances to have been crucial in advancing the development of welfare states and varieties of capitalism theoretically and empirically these claims are problematic in welfare state expansion employers have often been antagonists under specific conditions consenters but very rarely protagonists well developed welfare states and coordinated market economies have emerged in countries with strong left parties in long term cabinet participation or in countries with state corporatist institutional traditions and confessional parties in intensive competition with left parties

the turn of the year in money markets tests of the risk shifting window dressing and preferred habitat hypotheses musto 1997 identifies a turn of the year effect in the commercial paper market and offers risk shifting window dressing as an explanation we revisit this market with different methods and find strong evidence rejecting the risk shifting hypothesis we extend our analysis to other private issue money market instruments and find similar results we find further corroborating evidence in the 1 month t bill market and aggregate demand deposit data our results are consistent with a year end preferred habitat for liquidity associated with year end cash flow obligations

the turn of the year in canada a number of investigators have reported that january stock returns in the u s exceed returns for other months of the year this paper documents a similar finding for canadian stocks over the period 1951 1980 however canada did not introduce a capital gains tax until 1973 and the paper reports that january returns in canada exceed returns for other months of the year before and after this date thus these data do not support the tax loss selling pressure hypothesis as the entire explanation for the turnof the year effect in stock returns nor by implication do they support the tax lossselling pressure hypothesis as the complete explanation for the small firm effect in u s stocks returns recently keim 9 has reported that returns on nyse and ase firms with small market values exceed by significant margins returns on firms with large market values this result was previously reported by banz 1 and reinganum 11 but keim s analysis shows that most of the excess return for small firms is concentrated in january indeed it is concentrated in the first two weeks in january roll 13 also documents this phenomenon and investigates a number of possible explanations for it 2 after rejecting several possible nonexploitable explanations roll is left with year end tax loss selling pressure of the sort discussed by branch 2 dyl 5 and givoly and ovadia 6 as the most likely explanation of this result according to the tax loss selling pressure hypothesis toward the end of the year stockholders sell stocks that have declined in price during the year investors do this to take advantage of the opportunity to write off capital losses against ordinary income in computing their federal income taxes the year end sell off exerts downward pressure on stock prices as soon as the tax and calendar year ends the selling pressure is relieved and stock prices quickly rebound to their equilibrium levels roll 13 presents some evidence consistent with this hypothesis specifically he finds a negative correlation between stock returns in january and returns over the previous 12 months that is stocks that decrease in value during the year tend to be big gainers in january roll also finds that

does the organization of capital matter employers and active labor market policy at the national and firm levels does the organization of business matter for social policy development in the advanced capitalist democracies conventional welfare state analysis has given this significant question scant attention we argue however that the representational power of business coordination across business interest units and integration of associations in corporatist policy making forums or what we call the social corporatist organization of business should result in greater support and participation by employers in social policy formation and implementation we test our arguments with models both of 1980 98 pooled time series data on withinand across country variation in spending on active labor market programs and of extensive firm level survey data from denmark and the united kingdom we find that the centralization and coordination of employers as well as the integration of employer organizations in corporatist policy making forums are strongly associated with shares of national income devoted to active labor market policy we find moreover that the degree of employer organization conditions active labor market policy responses to de industrialization and increases in general unemployment at the firm level membership in an employer association has a significant positive effect on employer participation in active labor market programs in corporatist denmark but not in the pluralist united kingdom

political economy of pension plans impact of institutions gender and culture abstract national pension systems are an important part of financial intermediation and worker welfare in most countries but how and why do they differ internationally controlling for important political economic and social institutions we document that international differences in pension progressivity or how pensions reflect lifetime earnings are negatively related to masculinity uncertainty avoidance individualism long term orientation employment rights average pension levels social trust and economic inequality we also find that pension progressivity is positively related to the economic and societal role of women the extent of catholicism as well as political voice and accountability these results provide important insights for both public policy and mnc managers

stock price distributions with stochastic volatility an analytic approach we study the stock price distributions that arise when prices follow a diffusion process with a stochastically varying volatility parameter we use analytic techniques to derive an explicit closed form solution for the case where volatility is driven by an arithmetic ornstein ublenbeck or ar1 process we then apply our results to two related problems in the finance literature 1 options pricing in a world of stochastic volatility and 2 the relationship between stochastic volatility and the nature of fat tailes in stock price distributions article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

preferred habitat for liquidity in international short term interest rates abstract risk shifting window dressing and a preferred habitat for liquidity have been offered as possible explanations as to why us money market rates are higher before the year end than afterwards the two hypotheses differ in the timing of the rate decline at the year end and the evidence on the timing of the decline supports the preferred habitat hypothesis in us money markets this paper extends this line of research to the behavior of international short term interest rates at year ends and quarter ends using london interbank offer rates libor for 11 different currencies the results suggest that the behavior of libor for five currencies the us dollar euro japanese yen swiss franc and german mark is consistent with year end or quarter end preferred habitats for liquidity other currencies do not demonstrate consistently distinct patterns in turn of the year and turn of the quarter yields none of the results provides any support for risk shifting window dressing

has the minimum wage policy been important for reducing poverty in brazil a decomposition analysis for the period from 2002 to 2013 abstract this study aims to analyze the contribution of the minimum wage valorization policy to the reduction in poverty that occurred in the first decade of the 21st century in brazil considering not only the incidence of poverty but also its intensity and severity a decomposition methodology was used to isolate the marginal contribution of the minimum wage in the observed changes taking into account the roles of setting the values of basic pension and social assistance benefits the beneficio de prestacao continuada or bpc in addition to setting the wage floor between 2002 and 2013 the minimum wage contributed to a 38 2 reduction in the proportion of impoverished people a 39 4 reduction in the intensity of poverty and 40 6 decrease in the severity of poverty our results also reveal geographic differences with the minimum wage being more important in the poorest regions

the causes of welfare state expansion deindustrialization or globalization an influential line of argument holds that globalization causes economic uncertainty and spurs popular demands for compensatory welfare state spending this article argues that the relationship between globalization and welfare state expansion is spurious and that the engine of welfare state expansion since the 1960s has been deindustrialization based on cross sectional time series data for fifteen oecd countries the authors show that there is no relationship between globalization and the level of labor market risks in terms of employment and wages whereas the uncertainty and dislocations caused by deindustrialization have spurred electoral demands for welfare state compensation and risk sharing yet while differential rates of deindustri alization explain differences in the overall size of the welfare state its particular character in terms of the share of direct government provision and the equality of transfer payments is shaped by government partisanship the argument has implications for the study and the future of the welfare state that are very different from those suggested in the globalization literature

a further investigation of the weekend effect in stock returns this study uses a longer time period and additional stocks to further investigate the weekend effect we find consistently negative monday returns 1 for the s p composite as early as 1928 2 for exchange traded stocks of firms of all sizes and 3 for actively traded over the counter otc stocks the otc results are based on bid prices and therefore appear to reject specialist related explanations for the 30 individual stocks of the dow jones industrial index the average correlation between friday and monday returns is positive and the highest of all pairs of successive days the latter finding is inconsistent with fairly general measurement error explanations some of the most puzzling empirical findings reported in recent years indicate that the distribution of common stock returns varies by day of the week most notably the average return for monday close friday to close monday is significantly negative cross 3 and french 6 find negative monday returns using the standard and poor s composite index and gibbons and hess 7 find negative monday returns for the 30 individual stocks of the dow jones industrial index 1 this negative monday return or weekend effect has yet to be explained this study undertakes a further investigation of the weekend effect in stock returns we examine additional time periods extending the total period covered to 55 years we examine additional stocks such as those of small low capitalization firms and those traded over the counter in all cases the data exhibit a weekend effect that is at least as strong as that reported in previous studies the study also readdresses potential explanations for the effect such as measurement error but concludes that none of these explanations is satisfactory the first section presents a history of the weekend effect from 1928 through 1982 based on the standard and poor s composite index we essentially double the length of the period beginning in 1953 examined by french 6 the results indicate consistently negative monday returns throughout the 55 year period during much of the 25 year period from 1928 through 1952 the new york stock exchange was open on saturdays so monday s return is then computed from saturday s close to monday s close 2 these returns for one day weekends are consistently negative and not significantly different from the two day weekend

the price of a smile hedging and spanning in option markets the volatility smile changed drastically around the crash of 1987 and new option pricing models have been proposed to accommodate that change deterministic volatility models allow for more flexible volatility surfaces but refrain from introducing additional risk factors thus options are still redundant securities alternatively stochastic models introduce additional risk factors and options are then needed for spanning of the pricing kernel we develop a statistical test based on this difference in spanning using daily s p 500 index options data from 1986 95 our tests suggest that both in and out of the money options are needed for spanning the findings are inconsistent with deterministic volatility models but are consistent with stochastic models that incorporate additional priced risk factors such as stochastic volatility interest rates or jumps article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

throwing away a billion dollars the cost of suboptimal exercise strategies in the swaptions market abstract this paper studies the costs of applying single factor exercise strategies to american swap options when the term structure is actually driven by multiple factors using a multifactor string market model of the term structure we find that even when single factor models are recalibrated to match the market at every exercise date the exercise strategies they imply can be suboptimal based on estimates of notional amounts outstanding the total present value costs of following single factor strategies could be several billion dollars these results illustrate the importance of using well specified term structure models

model risk and capital reserves abstract we propose a procedure to take model risk into account in the computation of capital reserves this addresses the need to make the allocation of capital reserves to positions in given markets dependent on the extent to which reliable models are available the proposed procedure can be used in combination with any of the standard risk measures such as value at risk and expected shortfall we assume that models are obtained by usual econometric methods which allows us to distinguish between estimation risk and misspecification risk we discuss an additional source of risk which we refer to as identification risk by way of illustration we carry out calculations for equity and fx data sets in both markets estimation risk and misspecification risk together explain about half of the multiplication factors employed by the bank for international settlements bis

on the no arbitrage condition in option implied trees the aim of this paper is to discuss the no arbitrage condition in option implied trees based on forward induction and to propose a no arbitrage test that rules out the negative probabilities problem and hence enhances the pricing performance the no arbitrage condition takes into account two main features the position of the node in the tree and the relation between the dividend yield and the risk free rate the proposed methodology is tested in and out of sample with italian index options data and findings support a good pricing performance

reinventing welfare regimes employers and the implementation of active social policy denmark and britain have adopted quite similar active social reforms in which employers play a major role in the programmatic delivery of services however the implementation of the programs has differed dramatically in the two countries danish firms despite having had virtually no prior involvement in administering social programs have participated in far greater numbers than british employers who by contrast have long provided private employment based social benefits drawing from interviews with 107 randomly selected british and danish corporations this article seeks to explain why danish employers have participated at higher rates than their british counterparts subtle programmatic differences that reflect each country s welfare regime have had profound feedback effects on firms willingness to participate in the programs these findings have implications for regimes capacities both to correct for traps and to revise social protections to meet the needs of the new economy

seasonality in canadian stock prices a test of the tax loss selling hypothesis a popular hypothesis to explain the anomalous january returns of common stocks is based on the argument that there is considerable tax loss selling by investors toward the end of the year the purpose of this study is to test the tax loss selling hypothesis with data on canadian stocks although the introduction of capital gains tax in canada seems to have affected the behavior of stock returns the findings do not support the proposition that taxinduced trading is the sole cause ofthe seasonality in stock returns in canada i introduction over the past several years a number of studies have shown that the returns on common stocks in general and the stocks of small companies in particular tend to be abnormally high during the month of january keim 10 demonstrated quite clearly that a very high percentage of the abnormal positive returns gener ated on stocks with low market capitalizations occurs during january with the returns during the first five trading days of the year accounting for most of the anomalous behavior his results were recently confirmed by roll 14 who re ported that around 37 percent of the annual differences in the returns on the equally weighted and value weighted indices of nyse and amex stocks is ac counted for by what happens in the five trading days from the last trading day in december through the fourth trading day in january a popular hypothesis to explain the so called january effect in stock re turns is based on the argument that there is considerable end of the year tax lossselling by investors originally proposed by wachtel 19 it asserts that inves tors try to realize losses towards the end of the year to reduce their taxes thereby putting downward pressure on stock prices according to the hypothesis once

tax induced trading and the turn of the year anomaly an intraday study this study tests the tax induced trading hypothesis as an explanation of the turn of the year anomaly using canadian and u s intraday data since the canadian tax year end precedes the calendar year end by five business days tax effects may be isolated we find the anomaly is related to the degree of seller and buyer initiated trading and depends upon the incidence of the taxation year end seller initiated transactions at bid prices dominate until the tax year end after which buyer initiated trades at ask prices dominate the anomaly is a function of bid ask prices

the costs and determinants of order aggressiveness abstract this paper examines the costs and determinants of order aggressiveness aggressive orders have larger price impacts but smaller opportunity costs than passive orders price impacts are amplified by large orders small firms and volatile stock prices to minimize the implementation shortfall the optimal strategy is to enter buy sell orders at the bid ask aggressive buy sell orders tend to follow other aggressive buy sell orders and occur when bid ask spreads are narrow and depth on the same opposite side of the limit book is large small aggressive buys are more likely than sells to be motivated by information

an investigation of transactions data for nyse stocks using transactions data the behavior of returns and characteristics of trades at the micro level is examined a minute by minute market return series is formed and tested for normality and autocorrelation evidence of differences in return distributions is found among overnight trades trades during the first 30 minutes following the market opening trades at the close and trades during the remainder of the day the latter distribution is found to be normal unusually high returns and standard deviations of returns are found at the beginning and the end of the trading day when the beginningand end of the day effects are omitted autocorrelation in the market return series is reduced substantially a number of patterns in trading are reported this paper empirically investigates the nature of the return generating process and the characteristics of trade size price changes trading frequency and trading interval at the level of individual trades for a large sample of nyse stocks previous studies of market indices have used daily weekly or monthly

who gives who gains progressivity and preferences the extent to which popular support for the welfare state depends on income varies greatly across nations and policy domains we argue and show formally that these variations largely overlooked yet essential to understanding the politics of redistribution reflect in part the design of tax and transfer policies in terms of progressivity when progressivity is high politics is perceived by income groups as a zero sum game and conflicts over who gets what intensify when progressivity is low and tax contributors and benefit recipients overlap redistributive struggles become politically less salient we test these predictions both across nations and across policy domains within a sample of advanced industrial democracies our findings indicate that the progressivity of the tax and transfer system is a major determinant of the predictive power of income on preferences for redistribution

political resources and the growth of welfare in affluent capitalist democracies 1960 1982 explanations of welfare effort in affluent postwar democracies are partially integrated within a political resource framework political resource models of welfare effort fare well when tested with pooled time series data for 1960 82 use of governmental authority by the left use of disruption by the working class and the petty burgeois and use of lobbying voting and or entitlement rights by the elderly and the unemployed constitute means of political action among more diffusely available infraresources state revenue expansion economic growth and inflation appear to buoy welfre expansion as do left corporatism and bureaucratic paternalism some mediating effects of economic epoch and state structure are explored

on the suboptimality of single factor exercise strategies for bermudan swaptions abstract this paper resolves the disagreement between longstaff et al 2001 journal of finance economics 62 39 66 and andersen and andreasen 2001 journal of financial economics 62 3 37 over the effectiveness of the common business practice of using best fit single factor term structure models to deduce exercise strategies of bermudan swaptions i examine the cost of using recalibrated single factor models to determine the exercise strategy for bermudan swaptions in a multifactor world i show that single factor exercise strategies applied in a multifactor world only give rise to economically insignificant losses furthermore i find that the conditional model risk as defined in longstaff et al 2001 journal of finance economics 62 39 66 is statistically insignificant given the number of observations additional tests using the primal dual algorithm of andersen and broadie 2004 management science 50 9 indicate that losses found in longstaff et al 2001 journal of finance economics 62 39 66 cannot as claimed be ascribed to the number of factors

optimal stock trading with personal taxes implications for prices and the abnormal january returns abstract the tax law confers upon the investor a timing option to realize capital losses and defer capital gains with the tax rate on long term gains and losses being about half the short term rate the law provides a second timing option to realize losses short term and gains long term if at all our theory and simulation over the 1962 1977 period establish that taxable investors should realize long term gains in high variance stocks and repurchase stock in order to realize potential future losses short term tax trading does not explain the small firm anomaly but predicts a seasonal pattern in trading volume which maps into a seasonal pattern in stock prices the january anomaly only if investors are irrational or ignorant of the price seasonality

option prices implied price processes and stochastic volatility this paper characterizes all continuous price processes that are consistent with current option prices this extends derman and kani 1994 dupire 1994 1997 and rubinstein 1994 who only consider processes with deterministic volatility our characterization implies a volatility forecast that does not require a specific model only current option prices we show how arbitrary volatility processes can be adjusted to fit current option prices exactly just as interest rate processes can be adjusted to fit bond prices exactly the procedure works with many volatility models is fast to calibrate and can price exotic options efficiently using familiar lattice techniques

social policy by popular demand why are unemployment benefits more generous in some countries this article argues that citizens trade off the redistributive and insuring effect of social insurance as a result the distribution of risk in a society has important consequences via popular demand for social policy making at the microlevel the article shows that in addition to income the risk of unemployment is a key predictor of individual level preferences for unemployment benefits based on the microlevel findings the article argues that at the macrolevel the homogeneity of the risk pool is an important determinant of benefit generosity the more equally unemployment risk is distributed the higher unemployment replacement rates are empirical testing at both levels finds support for this account of social policy by popular demand

explaining social policy preferences evidence from the great recession to what extent do personal circumstances as compared to ideological dispositions drive voters preferences on welfare policy addressing this question is difficult because a person s ideological position can be an outcome of material interest rather than an independent source of preferences the article deals with this empirical challenge using an original panel study carried out over four years tracking the labor market experiences and the political attitudes of a national sample of americans before and after the eruption of the financial crisis the analysis shows that the personal experience of economic hardship particularly the loss of a job had a major effect on increasing support for welfare spending this effect was appreciably larger among republicans than among democrats a result that was not simply due to a ceiling effect however the large attitudinal shift was short lived dissipating as individuals employment situations improved the results indicate that the personal experience of an economic shock has a sizable yet overall transient effect on voters social policy preferences

do capital gain tax rate increases affect individual investors trading decisions abstract this paper examines individual investors short and long term trading reactions to the 1986 tax reform act s tra 86 capital gain tax rate increase consistent with a tax induced trading model we document a december 1986 change in year end trading patterns tra 86 also had long term effects on individual investors trading decisions the results suggest that individual investors were less more willing to sell accrued gain loss stocks after tra 86 our ability to document predicted trading behavior is in part due to our trading metric which captures individual investors selling activity better than the volume based metrics used in prior research

evidence on tax motivated securities trading behavior tax loss selling by investors in common stocks near the end of calendar years has been proposed as an explanation for the turn of the year effect in stock returns past analyses of this hypothesis have relied on inferential data we provide here some direct data from a compilation of over 80 000 actual common stock investment round trips by a sample of 3000 individual investors we find strong evidence of a concentration of loss taking trades late in the year and milder evidence of a concentration just prior to the dates when investments become eligible for long term tax treatment the question as to whether and in what manner the impostion of a tax on realized capital gains affects the securities trading behavior of investors who are subject to the tax has been a longstanding topic of research in the financial ecomonics literature the original attention devoted to the matter was motivated primarily by a concern about resource allocation and federal tax revenue consequences and was directed toward the phenomenon of what has been termed the lock in effect of a gains tax that issue has remained an important public policy one and continues today as part of the ongoing debate about appropriate strategies for reducing the federal budget deficit particular additional interest in the topic has emerged in recent years however because securities transactions undertaken systematically for tax reasons have also been proposed as part of the explanation for certain observed anomalies in historical common stock returns most prominently the well documented turn of the year effect our purpose here is to provide some new evidence that decisions by investors as to the timing of the realization of capital gains and losses from their common stock investments are significantly affected by tax considerations this evidence indicates that a difference in the tax rates applicable to realizations classified as short and long term influences the timing of individual investors trades and further that there is a clear tendency for trades by individuals which give rise to losses to be concentrated near the end of calendar which for them are also tax years while we cannot conclude that

capitalist systems deindustrialization and the politics of public education recent years have seen a number of studies on the determinants of educational spending almost all of the existing work emphasizes the importance of left wing governments as a motor of expansion because such expansion allegedly ensures both redistribution and the facilitation of a supply side economy the existing literature thereby corroborates the power resource theory against this common wisdom the article presents an argument building on the varieties of capitalism approach it is argued that education is a poor instrument for redistribution because access is universal and high income groups have a tendency to use education even more than low income groups instead we argue that deindustrialization is the main driver of educational spending because deindustrialization constitutes one of the most salient threats to workers in modern societies as deindustrialization rises workers risk ending up with redundant skills especially in countries where the average skills specificity is high that is coord

swedish economic performance and swedish economic debate a view from outside the papers by korpi henrekson and agell raise important questions both about the swedish economy and about the way in which evidence on economic growth should be handled in debate on economic policy i want to comment in particular on the fundamental question of whether the international evidence allows us to judge that swedish growth has been below par the papers raise two further questions on the first whether growth is inhibited by high taxation and a large welfare state the hallmarks of the post war swedish economy agell provides as good an assessment of the cross country macroeconomic evidence as we can probably hope to get at the moment unproven on the final vexed question of whether the structure of the economics profession has been inimical to open debate i have only a few comments to make let me start with the criteria and method by which we should attempt to assess relative economic performance this is a methodological minefield there are numerous paths leading to divergent conclusions the least we can do is to be explicit about our choices and subject our provisional conclusions to some checks for robustness what performance measure is relevant we could look at gdp or consumption scaled per head of population or per member of the workforce or per hour worked what deflators do we use we can reduce measures denominated in local currency to a common unit using exchange rates or using fixed international prices or using utility based indexes which derivative of the performance measure do we use we might want to compare levels or rankings or we might choose to assess relative rates of growth or even relative changes in growth rates which time period is relevant in particular comparisons of growth rates are often very sensitive to choice of start and end years when business cycle fluctuations are asynchronous what is the reference pointfor assessing underor overachievement the definition of par might be either the best performance or average performance for some group of countries for some period of time finally what exogenousfactors are to be taken into account we might wish to control for the influence on our preferred performance measure of a wide range of factors which are extraneous to the policy question under examination i will take a brisk jog through this minefield explaining briefly some of the choices which seem most relevant to the problem in hand but without attempting a full exposition of the problems the most usual starting place is to choose real gdp per capita as a measure of aggregate performance this

seasonalities in nyse bid ask spreads and stock returns in january using end of month bid ask spreads for 540 nyse stocks over the period 1982 1987 we document a seasonal pattern in which both relative and absolute spreads decline from the end of december to the end of the following january cross sectional regressions do not however provide evidence of a significant correlation between changes in spreads at the turn of the year and january stock returns either there is no cause and effect relation between the coincidental seasonals in bid ask spreads and january returns for nyse stocks or the data are too noisy to reveal any relation bid ask spreads hatve played and continue to play an important role in explanations of the january effect in stock returns for example roll 1983 argues persuasively that high january returns are the result of tax loss selling pressure that occurs throughout the year which is released right after the beginning of the new tax year once the selling pressure is released stocks rise in price which results in high january returns however these predictable excess january returns cannot be exploited fully by arbitrageurs because of round trip transactions costs in the form of the bid ask spread this inhibitor to arbitrage is especially great for small or low priced stocks where historically high january returns have been most pronounced stoll and whaley 1983 take a different tack they do not focus on january returns per se but argue that the excess returns on small stocks are a result of higher proportional bid ask spreads in low priced stocks in their view the bid ask spread itself is the cause of the higher returns on small stocks that is because of the higher proportional cost of transacting in small stocks investors demand a higher rate of return in response keim 1983 and schultz 1983 point out that small stock excess returns are concentrated in january and a seasonal in stock returns cannot be explained by the bid ask spread unless there is a seasonal in the bid ask spread as well schultz 1983 compares bid ask spreads in december with those in june plus round trip commissions for a sample of 40 small capitalization new york stock exchange nyse stocks and finds no signifi

misspecification and the pricing and hedging of long term foreign currency options abstract this study examines the effects of stochastic volatility upon the pricing and hedging of long term foreign currency options the traditional method of pricing such options uses a constant volatility option model with an implicit volatility derived from a short term traded option we show that the traditional method leads to small pricing errors for short and medium term options but does a poor job in pricing long term options the traditional method also does a poor job for all maturities in determining the derivatives of the option s value with respect to the exchange rate delta and the volatility vega the errors in calculating these derivatives which are used in forming the replicating portfolio lead to large and costly errors in error hedging

a paradox of redistribution in international aid the determinants of poverty oriented development assistance summary donors differ in the amount of official development assistance dedicated to poverty reduction we investigate the causes of variation over time and donors by employing both a regression approach with aggregate data on bilateral aid and two short country studies on germany and the united kingdom we find that there is a trade off between the total amount of money given and the amount of money given to poor countries the trade off is similar to the paradox of redistribution of targeting vs redistribution in rich welfare states case study evidence illustrates how countries have managed this tradeoff

institutional feedback and support for the welfare state the case of national health care researchers interested in the political consequences of the welfare state argue that cross country variations in the design of social policy institutions produce distinct patterns of public support for the welfare state this research proposes an institutional feedback effect in which welfare institutions once created transform political debate generate new constituencies and alter how individuals and interest groups interpret their preferences existing research has found mixed results for these proposed institutional feedback effects on public opinion this project contributes to research on institutional feedback through an analysis of cross national variation in public support for national health care national health care provides a unique opportunity for studying institutional feedback by avoiding problems with the measurement of key variables common to previous work in this area this research offers evidence in support of institutional feedback effects by demonstrating links between the struct

welfare states and social trust this article tests the linkage between institutional configuration and social trust highlighting the role of the welfare states in coordinating interests among different labor market actors this study initially builds a theoretical framework distinguishing training supplemented welfare regimes from transfer based welfare regimes evidence from descriptive and multivariate analyses of world values survey based on 17 advanced industrial democracies supports my argument that public investment in skill provision prevalent in training supplemented welfare states leads to higher accumulation of social trust whereas passive social transfers result in lower social trust especially high investment in public skill provision leads to a decreased gap in social trust between employers and low skilled workers as well as among different occupational groups in addition the negative effect of passive social transfers on trust is greatly ameliorated when it is jointly configured with high active labor market polici

risk management implications of time inconsistency model updating and recalibration of no arbitrage models a widespread approach in the implementation of asset pricing models is based on the periodic recalibration of its parameters and initial conditions to eliminate any conflict between model implied and market prices modern no arbitrage market models facilitate this procedure since their solution can usually be written in terms of the entire initial yield curve as a result the model fits by construction the interest rate term structure this procedure is however generally time inconsistent since the model at time t 0 completely specifies the set of possible term structures for any t 0 in this paper we analyze the pros and cons of this widespread approach in pricing and hedging both theoretically and empirically the theoretical section of the paper shows a under which conditions recalibration improves the hedging errors by limiting the propagation of an initial error b that recalibration introduces timeinconsistent errors that violate the self financing argument of the standard replication strategy the empirical section of the paper quantifies the trade off between a and b under several scenarios first we compare this trade off for two economies with and without model specification error then we discuss the trade off when the underlying economy is not markovian 2005 elsevier b v all rights reserved

the paradox of redistribution and strategies of equality welfare state institutions inequality and poverty in the western countries the structure of welfare state institutions 2 a trade off exists between the degree of low income targeting and the size of redistributive budgets 3 outcomes of market based distribution are often more unequal than those of earnings related social insurance programs we argue that social insurance institutions are of central importance for redistributive outcomes using new data our comparative analyses of the effects of different institutional types of welfare states on poverty and inequality indicate that institutional differences lead to unexpected outcomes and generate the paradox of redistribution the more we target benefits at the poor and the more concerned we are with creating equality via equal public transfers to all the less likely we are to reduce poverty and inequality social scientists and social reformers have long debated how the welfare state and social policies should be designed so as to best reduce poverty and inequality this debate involves two different issues one question concerns whether social policies should be targeted or universal that is should they be organized for the poor only or should the welfare state include all citizens in the context of nontargeted programs another question concerns the level of benefits should benefits be equal for all or should they be related to previous earnings and in

a methodology for assessing model risk and its application to the implied volatility function model we propose a methodology for assessing model risk and apply it to the implied volatility function ivf model this is a popular model among traders for valuing exotic options our research is different from other tests of the ivf model in that we reflect the traders practice of using the model for the relative pricing of exotic and plain vanilla options at one point in time we find little evidence of model risk when the ivf model is used to price and hedge compound options however there is significant model risk when it is used to price and hedge some barrier options

institutions and individuals at the turn of the year this article evaluates the tax loss selling hypothesis against the window dressing hypothesis as explanations for turn of the year anomalies we examine differences between securities dominated by individual investors versus those dominated by institutional investors and find that the effect is more pervasive in the former controlling for capitalization we find that in early january late december stocks with greater individual investor interest outperform underperform stocks with greater institutional investor interest these results hold for both stocks that previously appreciated in value and stocks that previously depreciated in value the results are most consistent with the tax loss selling hypothesis as an explanation for the turn of the year effect

a transaction data study of weekly and intradaily patterns in stock returns abstract weekly and intradaily patterns in common stock prices are examined using transaction data for large firms negative monday close to close returns accrue between the friday close and the monday open for smaller firms they accrue primarily during the monday trading day for all firms significant weekday differences in intraday returns accrue during the first 45 minutes after the market opens on monday mornings prices drop while on the other weekday mornings they rise otherwise the pattern of intraday returns is similar on all weekdays most notable is an increase in prices on the last trade of the day

volume and turn of the year behavior abstract this paper studies the trading characteristics of listed companies by size and year end behavior there were no transactions on nearly 25 of the days for the smallest decile even at the turn of year which is an active trading period for small companies as a result of low levels of trading and the regulations governing exchange specialists transaction prices and quotations of small listed companies may require several days to fully reflect equilibrium price changes the data confirm the existence of a year end seasonal pattern in rates of return for small companies and suggest that there may be a seasonal pattern for large companies as well

stopped in the name of the law administrative burden and its implications for cash transfer program effectiveness summary cash transfer programs have achieved wide ranging success in reducing poverty yet there is little empirical research on how program rules and administrative capacity might limit program effectiveness we examine administrative burden and quantify its implications for grant access and impacts in the south african child support grant csg program as the age of eligibility and application requirements changed over time we find that approximately 60 of the sampled children experienced an interruption or disconnection in cash transfer receipt and that both timing and dosage loss are associated with adolescent engagement in risky behaviors and for females lower educational attainment

determinants of relative poverty in advanced capitalist democracies using relative poverty measures based on micro level data from the luxembourg income study in conjunction with pooled time series data for 14 advanced capitalist democracies between 1970 and 1997 the authors analyze separately the rate of pretax transfer poverty and the reduction in poverty achieved by systems of taxes and transfers socioeconomic factors including de industrialization and unemployment largely explain pre tax transfer poverty rates of the working age population in these advanced capitalist democracies the extent of redistribution measured as poverty reduction via taxes and transfers is explained directly by welfare state generosity and constitutional structure number of veto points and the strength of the political left both in unions and in government

option mispricing around nontrading periods we find that option returns are significantly lower over nontrading periods the vast majority of which are weekends our evidence suggests that nontrading returns cannot be explained by risk but rather are the result of widespread and highly persistent option mispricing driven by the incorrect treatment of stock return variance during periods of market closure the size of the effect implies that the broad spectrum of finance research involving option prices should account for nontrading effects our study further suggests how alternative industry practices could improve the efficiency of option markets in a meaningful way
