state fiscal institutions and empty nest migration are tiebout voters hobbled abstract using the health and retirement study and a national panel of local fiscal data we test a lifecycle model of tiebout sorting on average cross state empty nest movers presumed to be out of fiscal equilibrium experience large fiscal gains in the form of reduced exposure to local school spending and property taxes while local empty nest movers experience no fiscal adjustment we find evidence that within state fiscal adjustment is constrained by state institutions that limit local discretion empty nest households moving within states with school finance equalization do not engage in tiebout consistent fiscal adjustment while those moving within states lacking school finance equalization adjust substantially

the influence of probability on risky choice a parametric examination abstract the appeal of expected utility theory as a basis for a descriptive model of risky decision making has diminished as a result of empirical evidence which suggests that individuals do not behave in a manner consistent with the prescriptive tenets of eut in this paper we explore the influence of probability on risky choice by proposing and estimating a parametric model of risky decision making our results suggest that models which provide for probability transformations are most appropriate for the majority of subjects further we find that the transformation differs for most subjects depending upon whether the risky outcomes are gains or losses most subjects are considerably less sensitive to changes in mid range probability than is proposed by the expected utility model and risk seeking behavior over long shot odds is common

day of the week effects and asset returns the number of empirical studies using daily stock returns is rapidly increasing researchers generally assume that the distribution of stock returns is identical for all days of the week a convenient statistical assumption but not a necessary condition of market equilibrium nevertheless there are reasons to suspect that the distribution of returns may vary according to the day of the week the most obvious is the impact of weekends on monday s return since monday s return is calculated over three instead of one calender day the mean and variance may well be higher on monday compared with any other daily return perhaps three times as large previous research has examined the daily distribution of stock returns for a monday effect while fama 1965 does not compare daily mean returns he does report that monday s variance is about 20o greater than other daily returns with a traditional distributional assumption regarding the returns on a financial asset specifies that the expected returns are identical for all days of the week contrary to this plausible assumption this paper discovers that the expected returns on common stocks and treasury bills are not constant across days of the week the most notable evidence is for monday s returns where the mean is unusually low or even negative several explanations of the results are investigated but none proves satisfactory aside from documenting significant day of the week effects the implications of the results for tests of market efficiency are examined while market adjusted returns continue to exhibit day of the week effects these effects are no longer concentrated on monday during the last year we have had many conversations with our colleagues throughout the professions we are particularly thankful to the participants at sessions of the western and american finance associations where preliminary versions of this paper were presented special thanks are due to gene fama gailen hite jon ingersoll robert jarrow merton miller clifford smith and rex thompson the expert research assistance of frank rabinovitch and youngsup yun is gratefully acknowledged 1 the list of papers using daily stock returns is too long to name recent examples include charest 1978 dodd 1980 banz 1981 and reinganum 1981

answering the skeptics yes standard volatility models do provide accurate forecasts a voluminous literature has emerged for modeling the temporal dependencies in financial market volatility using arch and stochastic volatility models while most of these studies have documented highly significant in sample parameter estimates and pronounced intertemporal volatility persistence traditional ex post forecast evaluation criteria suggest that the models provide seemingly poor volatility forecasts contrary to this contention we show that volatility models produce strikingly accurate interdaily forecasts for the latent volatility factor that would be of interest in most financial applications new methods for improved ex post interdaily volatility measurements based on high frequency intradaily data are also discussed

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

mobility behavior of the elderly mobility patterns of the elderly provide a particularly interesting theoretical subcase of a more general migration model which interacts individual specific traits e g health and retirement status and location specific traits e g amenities rents and wages the spatially invariant incomes pensions dividends etc of the retired are shown to lead to migration toward areas where the wage and rent compensation for amenities necessary for spatial equilibrium occurs primarily in the labor market rather than in the land market empirical evidence appears to be consistent with theoretical expectations more investigation however is clearly desirable

entrepreneurs perceived chances for success abstract entrepreneurs involved in planning or starting firms must engage in a continuing process of appraising prospects for success these assessments presumably bear upon the preparations they make as well as at some later point whether they decide to make major changes or even to discontinue the business in this study data from 2994 entrepreneurs who had recently become business owners were analyzed to determine their perceived changes of success although previous evidence on business survival led to the hypothesis that the entrepreneurs would only be cautiously optimistic this was not the case they perceived their prospects as very favorable with 81 seeing odds of 7 out of 10 or better and a remarkable 33 seeing odds of success of 10 out of 10 in considering the prospects for other businesses like their own they perceived odds which were significantly lower but still moderately favorable based upon previous research on factors associated with new business success it was hypothesized that those who were more likely to succeed based upon their personal backgrounds and the nature of their new firms would be more optimistic however this was not the case those who were poorly prepared were just as optimistic as those who were well prepared at this point shortly after having become business owners the assessment by entrepreneurs of their own likelihood of success was dramatically detached from past macro statistics from perceived prospects for peer businesses and from characteristics typically associated with higher performing new firms the psychological literature on post decisional bolstering suggests that decision makers in many settings tend to bolster or exaggerate the attractiveness of an option after it has been chosen this coupled with the tendency of entrepreneurs to believe that they can control their own destinies implies that the extreme optimism observed here is probably a typical occurrence for entrepreneurs the findings suggest that it is probably natural to experience feelings of entrepreneurial euphoria when first becoming a business owner with the available evidence it is difficult to judge whether this leads to inadequate preparations or an inability to diagnose problems and make adjustments after the business is started this extreme optimism probably does contribute to the heavy personal commitments observed here in which the median entrepreneur devoted more than 60 hours per week to the business the entrepreneur would seem well advised to form relationships with outsiders such as board members and professional advisors who can be objective and detached in diagnosing problems and assessing objectively the prospects for the business in its current form

psychological factors and stock option exercise we investigate stock option exercise decisions by over 50 000 employees at seven corporations controlling for economic factors psychological factors influence exercise consistent with psychological models of beliefs employees exercise in response to stock price trends exercise is positively related to stock returns during the preceding month and negatively related to returns over longer horizons consistent with psychological models of values that include reference points employee exercise activity roughly doubles when the stock price exceeds the maximum price attained during the previous year

decision making under uncertainty a field study of cumulative prospect theory abstract the presented research tests cumulative prospect theory cpt kahneman d tversky a 1979 prospect theory an analysis of decision under risk econometrica 47 263 291 tversky a kahneman d 1981 the framing of decisions and the psychology of choice science 211 453 480 in the financial market using us stock option data option prices possess information about actual investors preferences in such a way that an exploitation of conventional option analysis along with theoretical relationships makes it possible to elicit investor preferences the option data in this study serve for estimating the two essential elements of the cpt namely the value function and the probability weighting function the main part of the work focuses on the functions simultaneous estimation under cpt original parametric specification the shape of the estimated functions is found to be in line with theory comparing to results of laboratory experiments the estimated functions are closer to linearity and loss aversion is less pronounced

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

the informational content of implied volatility implied volatility is widely believed to be informationally superior to historical volatility because it is the markets forecast of future volatility but for s p 100 index options the most actively traded contract in the united states we find implied volatility in aggregate and across subsamples separated by maturity and strike price implied volatility has virtually no correlation with future volatility and it does not incorporate the information contained in recent observed volatility article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the risk premium that never was a fair value explanation of the volatility spread abstract we present a new framework to investigate the profitability of trading the volatility spread the upward bias on implied volatility as an estimator of future realized volatility the scheme incorporates the first four option implied moments in a growth optimal payoff that is statically replicated using a portfolio of options removing the upward bias on implied volatility worsens the likelihood score of risk neutral densities obtained from s p 500 index options when they are used as forecasts of the underlying index return distribution it also results in negative expected capital growth when they are used in a volatility arbitrage scheme our empirical finding is that the upward bias on implied volatility does not represent a long term return premium rather it is required to mitigate the large losses associated with tail events when trading volatility in options markets

the asymmetric impact of oil prices interest rates and oil price uncertainty on unemployment in the us abstract in this study we investigate the presence of asymmetric interactions between oil prices oil price uncertainty interest rates and unemployment in a cointegration framework utilizing the nonlinear auto regressive distributed lag nardl approach we show the asymmetric responses of unemployment to changes in oil prices oil price uncertainty and interest rates in the long run more specifically the results of our analyses suggest that an increase in oil price results in increased unemployment while there is no significant impact of reduced oil prices on the one hand reduced oil price uncertainty leads to a decrease in unemployment whereas an increase in oil price uncertainty does not have an impact we also observe increased unemployment in response to a decrease in interest rates as the impact of increased interest rates is not significant last but not least we find that option implied oil price volatility as a measure of oil price uncertainty outperforms the conditional volatility of crude oil prices in predicting unemployment this study provides valuable implications for policymakers to design sound economic policies

the day of the week effect the international evidence abstract we re examine the day of the week effect for eleven indexes from nine countries during the 1969 1992 period the standard methodology as well as the moving average methodology are used and we find returns to be lower at the beginning of the week but not necessarily on monday for the full period as in chang et al international evidence on the robustness of the day of the week effect journal of financial and quantitative analysis 28 1993 497 514 the anomaly disappears for the most recent period in the usa however the effect is still strong for european countries hong kong and toronto

an extension of the tiebout hypothesis of voting with one s feet the medicaid magnet hypothesis this study empirically extends the tiebout hypothesis of voting with one s feet in two ways first it provides updated estimates using net migration data for the period 2000 2008 second in addition to investigating variables reflecting public education outlays property taxation and income taxation it investigates whether migrants are attracted to states with higher medicaid benefits per recipient the latter hypothesis is referred to as the medicaid magnet hypothesis the analysis includes three economic variables three quality of life variables and three tiebout type factors in addition to medicaid benefits results indicate that consumer voters were attracted to states with higher per pupil public school spending lower property and income tax rates and that certain consumer voters may be attracted to states that offer higher levels of medicaid benefits

the effect of welfare and wage levels on the location decisions of female headed households abstract this paper develops and estimates a model designed to calculate the impact of welfare benefit levels wages and tax rates on the location choices of female headed households the empirical model assumes that women simultaneously choose both where they will live and whether or not they will participate in the welfare system based on their expected income and expected hours of work for each location participation possibility these income and hours expectations depend in turn on the welfare benefits wage and tax rates facing each household in each location it is found that both regional welfare levels and wage rates have a significant effect on the location decisions of this population the probability of a typical female headed household with little outside income leaving an area with low welfare payments and low wages can be as much as 12 points higher over a 4 year period than the probability of leaving a high welfare high wage area

the predictive power of implied volatility evidence from 35 futures markets abstract using data from 35 futures options markets from eight separate exchanges we test how well the implied volatilities ivs embedded in option prices predict subsequently realized volatility rv in the underlying futures we find that for this broad array of futures options iv performs well in a relative sense for a large majority of the commodities studied the implieds outperform historical volatility hv as a predictor of the subsequently rv in the underlying futures prices over the remaining life of the option indeed in most markets examined regardless of whether it is modeled as a simple moving average or in a garch framework hv contains no economically significant predictive information beyond what is already incorporated in iv these findings add to previous research that has focused on currency and crude oil futures by extending the analysis into a very broad array of contracts and exchanges our results are consistent with the hypothesis that futures options markets in general with their minimal trading frictions are efficient

the peculiar scale economies of lotto the best selling lottery game in the united states is lotto a parimutuel game of long odds and large jackpots unlike in the other popular lottery games numbers and instant there is a strong tendency for per capita lotto sales to increase with the size of the population base the fact that the jackpot also tends to increase with population size is not a complete explanation since the probability of winning tends to be inversely proportional to state population our explanation for why the games are more successful in large states is that players tend to judge the likelihood of winning based on the frequency with which someone wins then a larger state can offer a game at longer odds but the same perceived probability of winning as a smaller state this abstract was borrowed from another version of this item

income taxes and the destination of movers to multistate msas abstract we examine how differences in state income tax rates as well as other state and local taxes and public service expenditures influence the choice of state of residence for households federal tax filers moving into multistate metropolitan areas msas using data from the irs on the migration of taxpayers msas that are on borders provide a spatial discontinuity discrete differences in state tax rates within a single labor market these msas allow residents to live in one state and work in another state we find that differences in state income tax rates have a significant impact on the relative rate of migration to the states within an msa however contrary to what would be expected this impact is only significant in msas in which the filing state is based on employment states without reciprocity and not for those states in which the filing state is the state of residence states with reciprocity in msas where states do not have reciprocity agreements a difference of ten percent in tax rates leads to a 4 1 percent difference in the relative rate of incoming taxpayers analogously we find that a ten percent difference in state tax rates in these msas results in a 3 3 percent difference in the rate of tax base inflow agi our results suggest that one reason that differences in state income taxes appear to have more impact in multistate msas without reciprocity is that only relatively large differences in state income tax rates have any impact on migration and these differences are much more pronounced in msas without reciprocity

a micro econometric analysis of risk aversion and the decision to self insure this study estimates a von neumann morgenstern utility function using market data and micro econometric methods we investigate the decision whether to purchase insurance against the risk of telephone line trouble in the home using the choices of approximately 10 000 residential customers we determine the shape of the utility function and the degree of risk aversion we find that risk aversion varies systematically in the population and varies with the level of income and that the observed choice behavior is consistent with expected utility maximization we are unable to detect the presence of ambiguity effects or over weighting of low probability events

the directional volatility connectedness between crude oil and equity markets new evidence from implied volatility indexes in this paper we use a set of newly introduced implied volatility indexes to investigate the directional connectedness between oil and equities in eleven major stock exchanges around the globe from 2008 to 2015 the inference on the oil equity implied volatility relationships depends on diebold and yilmaz 2012 2014 2015 who proposed a set of directional measures that enable the dynamic and directional characterization of the relationships among financial variables we find uniform results across the sample countries indicating that the connectedness between oil and equity is established by the bi directional information spillovers between the two markets however we find that the bulk of association is largely dominated by the transmissions from the oil market to equity markets and not the other way around the pattern of transmissions is varying over the sample period however most of the linkages between oil and equities are established from the mid of 2009 to the mid of 2012 which is a period that witnessed the start of global recovery

loss aversion in a consumption savings model abstract we propose a model of consumption and saving based on kahneman and tversky s prospect theory that implies a fundamental asymmetry in consumption behavior inconsistent with other models of consumption when there is sufficient income uncertainty a person resists lowering consumption in response to bad news about future income this resistance is greater than the resistance to increasing consumption in response to good news we present empirical evidence from five countries that confirms this behavior

demographic change intergenerational linkages and public education in this brief paper i explore several issues related to u s demographic change and the political economy of public education i describe the existing empirical evidence that suggests that older and childless voters are less likely to support public school spending than younger voters with children i then note several unresolved issues about the degree to which rational self interest should lead older voters to vote for low levels of public school spending excerpt

a brief empirical note on the tiebout hypothesis and state income tax policies some years ago tiebout 1956 418 hypothesized that the consumervoter may be viewed as picking that community which best satisfies his preference pattern for public goods the consumer voter moves to that community whose local government best satisfies his set of preferences based upon this argument by tiebout this brief note seeks to empirically examine the impact of state income tax policy upon the geographic mobility of consumer voters in the united states more specifically we attempt to determine whether the existence of a state income tax significantly influences the in migration of consumer voters naturally the analysis includes suitable non tax control variables to reflect other factors which may influence the migration decision calculus

congressional influence on u s monetary policy abstract congressional influence is generally discounted or ignored in political models of federal reserve behavior here i show that changes in the leadership of the senate banking committee are significantly correlated with monetary base growth more liberal committee leaders are associated with significantly higher base growth other factors held constant the result is shown to hold across several econometric specifications and different definitions of the congressional preference variable

the relation between implied and realized volatility abstract previous research finds the volatility implied by s p 100 index option prices to be a biased and inefficient forecast of future volatility and to contain little or no incremental information beyond that in past realized volatility in contrast we find that implied volatility outperforms past volatility in forecasting future volatility and even subsumes the information content of past volatility in some of our specifications our results differ from previous studies because we use longer time series and nonoverlapping data a regime shift around the october 1987 crash explains why implied volatility is more biased in previous work

cumulative prospect theory option returns and the variance premium the variance premium and the pricing of out of the money otm equity index options are major challenges to standard asset pricing models we develop a tractable equilibrium model with cumulative prospect theory cpt preferences that can overcome both challenges the key insight is that the variance premium can be written as the expected return on a portfolio of otm call and put options and the probability weighting feature of cpt can explain the puzzlingly low returns observed for these options using gmm on a sample of u s index option returns between 1996 and 2010 we show that the cpt model ts well observed option prices and therefore the variance premium in a dynamic setting probability weighting and time varying equity return volatility combine to match the observed time series pattern of the variance premium

forecasting stock return variance toward an understanding of stochastic implied volatilities we examine the behavior of measured variances from the options market and the underlying stock market under the joint hypotheses that markets are informationally efficient and that option prices are explained by a particular asset pricing model forecasts from time series models of the stockreturn process should not have predictive content given the market forecast as embodied in option prices both in sample and out of sample tests suggest that this hypothesis can be rejected using simulations we show that biases inherent in the procedure we use to imply variances cannot explain this result thus we provide evidence inconsistent with the orthogonality restrictions of option pricing models that assume that variance risk is unpriced these results also have implicationsfor optimal variance forecast rules

on the existence of a political monetary cycle this paper examines electoral influence on monetary policy as measured by ml money growth i find a significant four year electoral cycle in money growth even when controlling for the influence of interest rates income and budget deficits further the residual electoral cycle produces the income and inflation movements associated with the political business cycle when it is used in simulations of simple reduced form macro models the paper concludes by discussing the difficulties in rationalizing cyclical monetary policy with rational expectations

the information content of implied volatilities and model free volatility expectations evidence from options written on individual stocks abstract we measure the volatility information content of stock options for individual firms using option prices for 149 us firms and the s p 100 index we use arch and regression models to compare volatility forecasts defined by historical stock returns at the money implied volatilities and model free volatility expectations for every firm for 1 day ahead estimation a historical arch model outperforms both of the volatility estimates extracted from option prices for 36 of the firms but the option forecasts are nearly always more informative for those firms that have the more actively traded options when the prediction horizon extends until the expiry date of the options the option forecasts are more informative than the historical volatility for 85 of the firms however at the money implied volatilities generally outperform the model free volatility expectations

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

predicting volatility in the foreign exchange market measures of volatility implied in option prices are widely believed to be the best available volatility forecasts in this article we examine the information content and predictive power of implied standard deviations isds derived from chicago mercantile exchange options on foreign currency futures the article finds that statistical time series models even when given the advantage of ex post parameter estimates are outperformed by isds isds however also appear to be biased volatility forecasts using simulations to investigate the robustness of these results the article finds that measurement errors and statistical problems can substantially distort inferences even accounting for these however isds appear to be too variable relative to future volatility it is widely believed that the volatility implied in option prices is the market s best estimate of future volatility after all if it were not one could devise a trading strategy that could generate profits by identifying mispriced options the purpose of this article is to investigate the information content and predictive power of volatility implied in options on foreign currencies the paper focuses on options on currency futures traded on the chicago mercantile exchange cme because of the depth and liquidity of cme futures and options traded side by side in the same market implied standard deviations isds allow for clean tests of the predictive power of implied volatilities early studies of the information content of isds have generally found that these contain substantial information for future volatility latane and rendleman 1976 chiras and manaster 1978 and beckers 1981 for example regress future volatility on the weighted implied volatility across a broad sample of chicago board options exchange cboe stocks and find that options contain volatility forecasts that are more accurate than historical measures 1 these studies performed shortly after the 1973 beginning of the cboe option market could only use a relatively short time span and therefore focused on cross sections rather than time series predictions

the behavior of the volatility implicit in the prices of stock index options abstract we examine stock market volatility around the quarterly expirations of stock index futures contracts and nonquarterly expirations of stock index options using estimates of the volatility implicit in the option prices the option prices reflect increases in the volatility of the underlying stock indexes around both quarterly and nonquarterly expiration dates analysis of the residual returns on index options provides evidence consistent with an unexpected increase in market volatility around expiration dates

theories of choice under risk insights from financial markets abstract to date the plausibility of theories of choice under risk hinges are mainly on experimental evidence this paper devises and implements an approach amenable of assessing the performance of three families of models expected utility rank dependent expected utility and the cumulative prospect theory using information from financial asset markets our findings unequivocally support reference point dependence diminishing marginal sensitivity loss aversion and nonlinear weighting of gain and loss physical probabilities the empirical observations are found to be robust to inter alia the parameterization of the utility and probability weighting functions day of the week effects the choice of a reference point and the introduction of possible low probability market crashes peso component

a theory of anticipated utility abstract a new theory of cardinal utility with an associated set of axioms is presented it is a generalization of the von neumann morgenstern expected utility theory which permits the analysis of phenomena associated with the distortion of subjective probability

political parties and the business cycle in the united states 1948 1984 this paper tests the existence and the extent of a politically induced business cycle in the u s in the post world war ii period the cycle described in this paper is different from the traditional political business cycle of nordhaus it is based on a systematic difference between the monetary policies of the two parties in a model with labor contracts from an explicit optimization problem we derive a system of equations for output and money growth then we successfully test the non linear restriction imposed by the theory on the parameters of the system of equations we cannot reject the hypothesis that money growth has been systematically different under the two types of administration and that this difference contributes to explain output fluctuations

slowing monetary growth since 1984 a public choice explanation until about 1984 the u s monetary base typically grew at an accelerating rate since then that acceleration has stopped modern evidence suggests that the federal reserve responds to political pressure we present empirical evidence supporting the hypothesis that reduced monetary base growth reflects the fact that the political advantages of price inflation have been significantly reduced by the tax indexation provisions of the economic recovery tax act of 1981

estimating quadratic variation using realized variance this paper looks at some recent work on estimating quadratic variation using realised variance rv that is sums of m squared returns this econometrics has been motivated by the advent of the common availability of high frequency financial return data when the underlying process is a semimartingale we recall the fundamental result that rv is a consistent as m estimator of quadratic variation qv we express concern that without additional assumptions it seems difficult to give any measure of uncertainty of the rv in this context the position dramatically changes when we work with a rather general sv model which is a special case of the semimartingale model then qv is integrated variance and we can derive the asymptotic distribution of the rv and its rate of convergence these results do not require us to specify a model for either the drift or volatility functions although we have to impose some weak regularity assumptions we illustrate the use of the limit theory on some exchange rate data and some stock data we show that even with large values of m the rv is sometimes a quite noisy estimator of integrated variance

option pricing of earnings announcement risks this paper uses option prices to learn about the equity price uncertainty surrounding information released on earnings announcement dates to do this we introduce reduced form models and estimators to separate price uncertainty regarding earnings announcements from normal day to day volatility empirically we find strong support for the importance of earnings announcements we find that the anticipated price uncertainty is quantitatively large varies across time and is informative about the future return volatility finally we quantify the impact of earnings announcements on formal option pricing models

stock splits volatility increases and implied volatilities a test of the efficiency of the chicago board options exchange relative to post split increases in the volatility of common stocks is presented the black scholes and roll option pricing formulas are used to examine the behavior of implied standard deviations isds around split announcement and ex dates comparisons with a control group of stocks find no relative increase in isds of stocks announcing splits however a relative increase is detected at the ex date therefore the joint hypothesis that 1 the blackscholes and roll formulas are true and 2 the cboe is efficient can be rejected recent studies by ohlson and penman 1985 dravid 1984 and dubofsky and french 1985 have documented significant increases in the observed variance of common stock returns subsequent to splits larger than 25 this is surprising because in theory no real event is associated with the actual day of the split dravid 1988 and lim and vijh 1986 have tried to explain the postsplit variance increase as the effect of stock price discreteness and the bid ask spread the evidence in lim and vijh 1986 and ohlson and penman 1985 suggests however that this is at best a partial explanation 2 although the causes of the volatility increase are not apparent the post split volatility increase should increase prices of calls on the splitting stock that expire after the ex date relative to those that expire before the ex date similarly prices of post split expiration calls on splitting stocks should increase relative to prices of calls on stocks that do not split in an efficient options market these relative price changes should occur at the announcement of the split in fact

honey i shrunk the kids benefits revisiting intergenerational conflict in oecd countries intergenerational conflict may arise when the interests of different age groups do not align we examine cross country data to find evidence for this conflict in oecd countries we derive our results from a fgls estimation model which is complemented by a system gmm estimation to account for potential endogeneity the data are from a panel of 22 oecd countries over the time period 1985 2005 we find little support for intergenerational conflict in general however those who are close to statutory retirement age dislike public expenditure on families and education because once they retire they will have less income compared to their work income this effect is transitory however implying a change in voting behavior during retirement age

developments in non expected utility theory the hunt for a descriptive theory of choice under risk this article reviews recent developments in the economic theory of individual decision making under risk since the 1950s it has been known that individual choices violate the standard model of expected utility in predictable ways considerable research effort has now been devoted to the project of developing a superior descriptive model following an overview of non expected utility theories which distinguishes between conventional and non conventional approaches the paper seeks to assess these alternative models in terms of empirical success using laboratory and field data and theoretical usefulness the closing sections reflect on some new directions emerging in this literature

the persistence of volatility and stock market fluctuations this paper examines the potential influence of changing volatility in stock market prices on the level of stock market prices it demonstrates that volatility is only weakly serially correlated implying that shocks to volatility do not persist these shocks can therefore have only a small impact on stockmarket prices since changes in volatility affect expected required rates of return for relatively short intervals these findings lead us to be skeptical of recent claims that the stock market s poor performance during the 1970 s can be explained by volatility induced increases in risk premia this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

modeling and predicting the cboe market volatility index abstract this paper performs a thorough statistical examination of the time series properties of the daily market volatility index vix from the chicago board options exchange cboe the motivation lies not only on the widespread consensus that the vix is a barometer of the overall market sentiment as to what concerns investors risk appetite but also on the fact that there are many trading strategies that rely on the vix index for hedging and speculative purposes preliminary analysis suggests that the vix index displays long range dependence this is well in line with the strong empirical evidence in the literature supporting long memory in both options implied and realized variances we thus resort to both parametric and semiparametric heterogeneous autoregressive har processes for modeling and forecasting purposes our main findings are as follows first we confirm the evidence in the literature that there is a negative relationship between the vix index and the s p 500 index return as well as a positive contemporaneous link with the volume of the s p 500 index second the term spread has a slightly negative long run impact in the vix index when possible multicollinearity and endogeneity are controlled for finally we cannot reject the linearity of the above relationships neither in sample nor out of sample as for the latter we actually show that it is pretty hard to beat the pure har process because of the very persistent nature of the vix index

presidential elections and federal reserve policy an empirical test traditional macro economic models of federal reserve fed behavior typically assume that the fed enjoys a well defined objective function based on social welfare and generally predict counter cyclical monetary policy the increasing observation of procyclical monetary policy has led many researchers to investigate new models of fed behavior several recent papers imply that procyclical fed behavior is due to a lack of political accountability friedman 7 toma 23 and shughart and tollison 21 all attribute considerable bureaucratic discretion to the fed and seek to explain monetary policy by examining typical bureaucratic objectives other papers such as pierce 19 20 weintraub 26 and kane 10 11 argue that the fed operates in an arena filled with political constraints that cause sub optimal monetary policy but these constraints are not modeled explicitly one possible political constraint on fed behavior is the incumbent president s desire for re election in the political business cycle pbc literature presidential re election opportunities are enhanced by the production of a precise set of inflation and unemployment outcomes leading up to the election thus to the extent that presidents desire cyclical macro economic outcomes there will be executive pressure on the fed to create or accommodate such outcomes the effect this pressure will have on fed policy is ultimately an empirical question but most models deal with it by assumption traditional macro modeling assumes a zero effect while the pbc models implicitly assume that a favorable election cycle is a primary goal of all economic policymakers this paper examines presidential influence on the federal reserve by testing for an election cycle in money growth the major result is the identification of a regular 16 quarter cycle in money growth corresponding with presidential elections this cyclical effect is found to be stable over time and significant under a wide range of model specifications further when the cyclical component of money growth is used to simulate a simple macro model it produces a classic political business cycle in inflation and real output growth

elections and the fed is there a political monetary cycle to understand the political causes of macroeconomic policy it is necessary to examine the institutions that actually make such policy and the incentives those institutions face an explanation of the political causes of united states monetary policy must treat the various institutions that are influential in the monetary policy process which are at a minimum the federal reserve fed and the executive including the president the treasury department and other advisors in the executive office of the president the reelection motive has proven useful in modeling presidential incentives in this article i investigate whether electoral incentives associated with the theory of the political business cycle pbc can help to explain the behavior of the fed over the last quarter century the political business cycle has had a curious hold on modern political economy while the empirical evidence in favor of the cycle is far from overwhelming its theoretical importance leads to continuing empirical

welfare policies and migration of the poor in the united states an empirical note this paper has investigated the impact of geographic welfare benefit differentials upon migration in the united states unlike other related studies which typically focus upon black migration as a surrogate measure of migration of the poor the present study focuses directly upon migration of the poor per se a variety of reduced form estimates are provided the evidence strongly suggests that the net in migration of the poor is positively and significantly influenced by higher nominal afdc levels and by higher real afdc levels these findings support the welfare magnet hypothesis which alleges that relatively high welfare levels act to attract poor migrants moreover given that poor migrants are attracted non only by high nominal welfare levels but also by high real welfare levels an argument can be made for establishing geographically uniform real welfare benefit levels in the united states this uniformity presumably should act over the long run to eliminate the human resource distortions being caused by the currently prevailing welfare system

labor supply of new york city cabdrivers one day at a time life cycle models of labor supply predict a positive relationship between hours supplied and transitory changes in wages because such changes have virtually no effect on life cycle wealth previous attempts to test this hypothesis empirically with time series data have not been supportive estimated elasticities are typically negative or nonsignificant such analyses however are vulnerable to measurement error and other estimation problems we use data on daily observations of wages and hours for new york city cab drivers to estimate the supply response to transitory fluctuations in wages cab drivers decide daily how many hours to supply and face wages that are positively correlated within days but largely uncorrelated between days using these data our central finding is that wage elasticities are persistently negative from 5 to 1 in three different samples even after correcting for measurement error using instrumental variables these negative wage elasticities challenge the notion that cab drivers trade off labor and leisure at different points in time and question the empirical adequacy of life cycle formulations of labor supply

general properties of option prices when the underlying price process is a one dimensional diffusion as well as in certain restricted stochastic volatility settings a contingent claim s delta is bounded by the infimum and supremum of its delta at maturity further if the claim s payoff is convex concave the claim s price is a convex concave function of the underlying asset s value however when volatility is less specialized or when the underlying process is discontinuous or non markovian a call s price can be a decreasing concave function of the underlying price over some range increasing with the passage of time and decreasing in the level of interest rates much of the financial options literature derives precise option prices when the underlying asset price process is completely specified since it is empirically difficult to ascertain what the true underlying process is another part of that literature is concerned with deriving general properties of option prices when the underlying price process is not fully specified but instead is assumed to belong to some general class of stochastic processes merton 1973 cox and ross 1976 jagannathan 1984 in particular in the absence of arbitrage opportunities and assuming that the risk neutralized stock price follows a proportional stochastic process a risk neutral return distribution independent of price merton 1973 and jagannathan 1984 show that a call option s price is an increasing convex function of the stock price cox and ross 1976

the political economy of the peace dividend we develop a model of the peace dividend and use it to predict the fiscal consequences of a reduction in the demand for military spending the model is based on the assumption that the political process responds to political demands and costs in a way that maximizes net political benefits the predictions of our model on how a peace dividend will be allocated over nonmilitary spending tax relief and deficit reduction is tested against the experience of eight major wars in united states history

friedman tax cuts vs buchanan deficit reduction as the best way of constraining government i introduction both milton friedman and james buchanan believe that the federal government spends more than can be justified on the basis of economic efficiency both also agree that the reason for excessive government spending is that the political process allows people to realize the benefits from government spending without fully paying the cost of that spending but friedman and buchanan are in apparent disagreement on the effectiveness of alternative approaches at constraining government by considering friedman and buchanan s apparent disagreement at the level of fiscal policy it is possible to better understand their agreement at the level of constitutional policy milton friedman has argued that a reduction in taxes and tax revenues with an increase in the budget deficit serves the useful function of restraining government spending for example friedman 1982 60 61 has written i want to cut tax rates but if the lafferites were correct in the extreme form that a particular cut in taxes increased revenue then my conclusion would be that we hadn t cut tax rates enough because what i want to cut is government revenue that s what feeds government spending what they the big spenders want is to increase taxes so they will have more money to spend and won t have to cut spending the triumph in my opinion of the tax cutting policy that president reagan has been following is that he has made the big spenders talk on his terms for the first time they have to face up seriously to cutting spending 1 in contrast james buchanan argues that reducing taxes and increasing debt financing lowers the perceived cost of government spending and consequently increases government spending for example buchanan and wagner 1977 138 139 state the replacement of current tax financing by government borrowing has the effect of reducing the perceived price of government goods and services with the result that taxpayers increase their demands for such goods and services preferred budget levels will be higher and these preferences will be sensed by politicians and translated into political outcomes in discussing the economic policy of the reagan administration william niskanen who was a member and acting chairman of the president s council of economic advisers during the reagan presidency takes note of the conflicting views of friedman and buchanan according to niskanen 1988 109 milton friedman promoted a view that tax rates should be reduced at every opportunity believing that the resulting increase in the deficit would increase pressure to reduce federal spending james buchanan expressed a directly contrary view that a tax increase would reduce spending by increasing the perceived price of government services to the current voters niskanen continues by expressing his leanings toward the buchanan view a leaning based on his own research niskanen 1978 he points out however that recent empirical work is inconclusive with some supporting friedman s position and some supporting buchanan s niskanen 1988 109 concludes his discussion of the difference of opinion between friedman and buchanan by observing that economists and politicians unfortunately do not yet share a clear understanding of these taxing spending and budget deficit relations a simple model of taxation spending and deficit determination provides a framework for examining systematically the conflict between friedman and buchanan it makes clear that the relationships among these variables cannot be determined by empirical investigation alone because both the friedman and buchanan positions emerge as special cases of a more general model it is not surprising that empirical studies can be found to support either position indeed we demonstrate that historic episodes exist which support the positions of both men ii the model political decisions like market decisions are made in response to benefits and costs

do the elderly vote with their feet this research explores whether the elderly vote with their feet by migrating to states with government policies that treat them favorably a theoretical model is presented that clarifies the effects of cost of living amenities and the public sector on migration decisions and that informs our empirical analysis using state level migration data from the 1990 census we estimate out migration and in migration equations that suggest that the public sector is an important determinant of elderly migration but in sometimes unexpected ways our results lend some support for the tiebout hypothesis but they also raise serious questions about the nature of the elderly s preferences for government policy
