the demand for lotto the role of conscious selection this article presents estimates of the elasticity of demand for lottery tickets using time series data in which there is variation in the expected value of a lottery ticket induced by rollovers an important feature of our data is that there are far more rollovers than expected given the lottery design we find strong evidence that individuals do not choose their lottery numbers uniformly from a uniform distribution that is conscious selection we use our estimates to derive the inverse supply function for the industry and this enables us to identify the demand elasticity we find the price elasticity to be close to unity which implies that the operator is revenue maximizing which is the regulator s objective

endogenous lifetime and economic growth abstract endogenous mortality is introduced in a two period overlapping generations model probability of surviving from the first period to the next depends upon health capital that is augmented through public investment high mortality societies do not grow fast since shorter lifespans discourage savings development traps are possible productivity differences across nations result in persistent differences in capital output ratios and relatively larger gaps in income and mortality high mortality also reduces returns on education where risks are undiversifiable when human capital drives economic growth countries differing in health capital do not converge to similar living standards threshold effects may also result

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

the who and why of lottery empirical highlights from the seminal economic literature lotteries operate today in many countries around the world this type of gambling is usually run by governments and is sometimes described as regressive lottery is an unfair bet so explaining the purchase of lottery tickets by risk averse consumers has been a challenge for economic theory lotteries can be analysed from either of two economic perspectives as a source of public revenue or as a consumer commodity in this paper the state of economic research on lotteries is reviewed focusing on its main empirical findings

intergenerational income group mobility and differential fertility one question development economists are especially interested in but so far left unanswered is how would the societal income distribution be affected by introducing a family planning program to reduce the reproduction rate of the poor which is usually high in developing countries the purpose of this paper is to search for analytical answers to this question we are able to make definite comparisons about some class of inequality measures of the steady state societal income distributions and these comparisons provide strong theoretical support in favor of the above mentioned family planning program excerpt

can tax loss selling explain the january seasonal in stock returns this paper analyzes the tax loss selling hypothesis as an explanation of the january seasonal in stock returns and argues that rational tax loss selling implies little relation between the january seasonal and the long term loss empirical results show that the january seasonal is as strongly related to the long term loss as it is to the short term loss the evidence is inconsistent with a model that explains the january seasonal by optimal tax trading

seasonalities in security returns the case of earnings announcements abstract we document a seasonal pattern in stock returns around quarterly earnings announcement dates small firms show large positive abnormal returns and a sizable increase in the variability of returns around these dates only part of the large abnormal returns can be accounted for by the tendency of firms with good news to announce early large firms show no abnormal returns around announcement dates and a much smaller increase in variability

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

economic shocks and lottery sales an examination of maine state lottery sales most u s states earn significant amount of revenues from lottery sales however they are also criticized for promoting the lotteries because they have been seen as taking advantage of poor popula

buying a dream alternative models of demand for lotto existing lotto demand models utilize effective price computed as the face value of a ticket minus the expected value of prize money per ticket as their primary explanatory variable by contrast this article proposes a key role for consumption benefit or fun in the demand for gambling in general and lotto demand in particular it develops an alternative model of lotto demand that focuses on the maximum possible prize when this is tested against the traditional model using data from the u k national lottery we find that jackpot considerations exert an influence over and above that of variations in effective price

the infant mortality fertility debate some international evidence the aim of this paper is to analyze empirically the causal relationship if any between infant mortality and fertility in thirty five developing countries the focus is on possible relationships between the infant mortality rate and the fertility rate the hypothesis that infant mortality causes fertility is tested the possibility of a reverse causation is also analyzed a one sided distributed lag test as proposed by granger is employed the results are analyzed in light of several versions of the mortality fertility proposition including demographic transition theory choice theory ricardian theory and the modern economic theory of population excerpt

a microeconomic analysis of the timing of births abstract the effects of personal characteristics wage rates and career structures on the time profile of childbearing among married couples are examined theoretically through an intertemporal microeconomic model of family decisions and empirically by an econometric analysis of british women s childbearing and work histories the effects of the mother s age on the quality of the child and the financial implications of interrupting the mother s career to care for a child are taken explicitly into account the demographic consequences of economic policies are also examined

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

stock return seasonalities and earnings information previous literature documents significant seasonalities in stock market returns one explanation is seasonality in earnings information if true a return index comprised solely of firms reporting earnings should exhibit stronger intertemporal seasonalities than a return index comprised of firms not reporting earnings employing all new york and american stock exchange firms over six years this study examines the seasonality of stock returns generally seasonal patterns for reporting returns are found to be similar to or slightly weaker than for nonreporting returns thus it is doubtful that earnings news seasonality induces stock return seasonality

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

can expected utility theory explain gambling we investigate the ability of expected utility theory to account for simultaneous gambling and insurance contrary to a previous claim that borrowing and lending in perfect capital markets rules out a demand for gambles we show that expected utility theory with non concave utility functions can still explain gambling when the rates of interest and time preference are equal agents will seek to gamble unless income falls in a finite set of exceptional values when these rates differ there will be a range of incomes for which gambles are desired in both cases repeated gambling is not explained but market imperfections such as different borrowing and lending rates can account for persistent gambling provided the rates span the rate of time preference

causal relationships between infant mortality and fertility in developedand less developed countries fertility reduction seems to be a nearly universal feature of the development of modern secular societies 5 208 the lagged response of fertility to reductions in mortality manifested in the lack of coordinated fertility control programs has historically resulted in high growth rates of population in the less developed countries e g latin american countries 1 2 over the past two decades the causal relationships between infant mortality and fertility have been a controversial issue 16 29 since the direction of this causality is not established on empirical grounds many existing estimates of fertility demand functions and infant survival production and demand functions are marred by simultaneous equation bias the purpose of this study is to examine the dynamic relationships between infant mortality and fertility by applying time series techniques to the annual data on these variables for economically developed countries and for economically less developed countries first i examine causal relationships within a two variable model infant mortality and fertility rates for a sample of economically developed countries including the western european countries of denmark finland france norway portugal switzerland and the united kingdom the u k and the united states u s a the time periods studied are 1939 74 for most of the european countries 1942 74 and 1944 74 for the u k and 1923 77 for u s a 3

what is the optimal design for lottery linked savings programmes in this article we determine the optimal design of lottery linked savings lls programmes lls vehicles such as lottery bonds are financial instruments that preserve depositors principal but provide randomized variable returns to these depositors through periodic lottery drawings in lieu of the regular coupon payments traditionally received by bondholders this type of asset is very popular in europe we note that the framing of lls instruments is linked to their popularity and we attempt to elucidate that link and thereby determine the optimal structure of payments for lls programmes our goal is to frame lls programmes in a manner that both maximizes their investors satisfaction and preserves their ability to serve as inexpensive sources of capital for their issuers we demonstrate that the optimal pay off structure is characterized by a high level of skewness as investors are willing to accept a decrease in the small and medium prizes of the lottery in exchange for an increase in the grand pri

on lottery sales jackpot sizes and irrationality a cautionary note jackpot size has a greater impact than expected price as a determinant of lottery sales suggesting that agents exhibit irrational lotto mania we demonstrate why this conclusion is problematical by considering the reduced form obtained if agents are described by cumulative prospect theory

mortality fertility and persistent income inequality many developing countries are characterized by high and persistent inequality in the distribution of income while a growing body of literature emphasizes differential fertility as a channel through which income inequality persists this paper investigates differential child mortality differences in the incidence of child mortality among different income groups as a critical link in this regard we incorporate both endogenous child mortality and endogenous fertility in an overlapping generations model we demonstrate that differential child mortality and its interaction with differential fertility can generate an income inequality trap where high risk of child death prevents poor households from adequately investing in education empirical evidence based on cross country micro data support differential child mortality as an important channel for the transmission of inequality as predicted by the model from a policy perspective the results suggest that better access to child health care may be a more promising way to reduce income inequality than providing incentives to lower the family size of poor households

productive government expenditures and long run growth the purpose of this paper is to review some of the recent developments in endogenous growth models specifically our focus is on the growth effects of productive government spending in dynamic general equilibrium models we use a simple overlapping generations model as our basic framework and illustrate the role of taxes and spending we then examine several related issues nonrivalry in publicly provided goods existence and uniqueness of competitive equilibrium endogenous public policy ways of financing public expenditures composition of publicly provided goods and services and private alternatives finally we review some empirical results related to output elasticity of public capital and educational expenditures

exotic betting opportunities pricing policies and the demand for parimutuel horse race wagering parimutuel horse race wagering has been declining steadily for the past several decades this has resulted in lower revenues to state governments recetracks adn horseman to retard or reverse this trend attempts have been made to implement a number of pricing and marketing strategies among these has been the introduction of a variety of exotic wagering opportunities over the years the number and type of exotic wagers offered has been increased furthermore the prices of both straight and exotic wagers have been increased and in addition the price of exotic wagers has generally been set at a higher rate than that for straight wagers the paper examines the effectiveness of these policies

from t bills to common stocks investigating the generality of intra week return seasonality the authors investigate the extent to which intra week seasonality still exists and whether its pattern is uniform across three stock indices and treasury bonds with seven different maturities they find that intra week seasonality continues to be significant and that its pattern is not uniform either between the stock indices and the treasury bonds or even among the bonds alone a pattern shared by stocks and bonds is that monday returns become increasingly negative with maturity these findings suggest that neither institutional nor general equilibrium explanations by themselves can explain the pattern of intra week seasonality in securities markets

an economist s guide to lottery design this paper outlines the issues relevant to the design of pari mutuel lottery games and makes inferences about game design effects from estimates of how rollovers affect sales lottery tickets sales depend positively on the proportion of revenue returned as prizes positively on the skewness of the prize distribution which depends largely on how much of the prize money goes to the jackpot and negatively on the variance in the prize distribution which depends largely on how much goes on smaller prizes we simulate the effects of envisaged game design changes on sales revenue and find potentially large effects

habit and long memory in uk lottery sales long memory processes can occur as a consequence of aggregation over heterogeneous agents we examine the uk lottery and by estimating the level of fractional differencing find evidence of the long memory property in lottery sales a result that has broader implications on the estimation of demand models for lotteries

day of the week and intraday effects in stock returns abstract this study examines day of the week effects using hourly values of the dow jones industrial average we find that over the 1963 1983 period the weekend effect has sifted from characterizing active trading on monday to characterizing the non trading weekend over the early part of our sample period negative returns characterize each hour of trading on monday while the return from friday close to monday open is positive in the most recent subperiod monday average hourly returns after noon are all positive and the weekend effect is due to negative average returns from friday close to monday open

the welfare effects of lotto evidence from the uk abstract this paper estimates the demand for lottery tickets using pooled cross section data that contain individual incomes and extensive information about characteristics one of the cross sections corresponded to a draw which was a double rollover the jackpot was enhanced by adding the two previous draws jackpots which had not been won together these datasets provide sufficient observations facing different prices to allow us to estimate the price elasticity as well as the income elasticity of demand we estimate tobit and other specifications and use the estimates to evaluate the welfare effects arising from the introduction of the lottery

explaining the facts with adaptive agents the case of mutual fund flows abstract this paper studies portfolio decisions of boundedly rational agents in a financial market learning is modeled via a genetic algorithm learning as modeled in this paper leads agents to hold too much risk as compared to the optimal portfolio of rational investors moreover adaptive agents exhibit an asymmetric response after positive and negative returns where the portfolio adjustment is more pronounced after negative returns it is demonstrated that investors in mutual funds show the same investment patterns as the adaptive agents in the model a model with entry and exit of agents is able to match the mutual fund data closely

the asian crisis and calendar effects on stock returns in thailand abstract this paper systematically examines daily returns of the thai stock market index to determine whether there is evidence of calendar effects due to the day of the week the month of the year days before or after holidays and within month effects particular attention is given to the evidence of these anomalies prior to during and after the asian crisis most of the previous empirical evidence examines each of these effects in isolation the approach adopted within this paper is to start with a general model which incorporates a range of different calendar anomalies before estimating the conditional volatility models daily data from 3rd january 1995 to 29th december 2000 are used for estimation providing 1473 observations the final models are tested by comparing their forecast performance for 2001 244 observations with various models which do not include calendar effects the conclusion is that the inclusion of calendar effects improves the forecast accuracy

jointly determined saving and fertility behaviour theory and estimates for germany italy uk and usa abstract the comparative statics predictions of models of the joint determination of household saving and fertility are derived under various hypotheses self interest altruism of parents towards children altruism of children towards parents etc and compared with those of models which determine saving under the assumption of exogenous fertility country specific saving and fertility equations are then estimated using time series data for germany italy uk and usa for each of the countries considered the estimates are consistent with the hypothesis that saving and fertility are jointly determined by self interested parents and reject the alternative hypotheses the data also show that a self financing expansion of social security discourages fertility and generally raises household saving

optimal lottery design for public financing this article develops a model of optimal lottery design for public financing on the assumption that economic agents view buying lottery tickets as a form of entertainment given that lotteries are optimally designed it offers two findings 1 the fundraising potential of a lottery is independent of its type specifically of whether it is a fixed prize type or a pari mutuel and 2 the ratio of the optimal winning prize amount in each prize class to total lottery sales is equalised to the elasticity of demand for lottery ticket purchases with respect to the winning prize in each prize class

self selection and the earnings of immigrants this paper analyzes the way in which the earnings of the immigrant population may be expected to differ from the earnings of the native population because of the endogeneity of the decision to migrate the empirical study shows that differences in the u s earnings of immigrants with the same measured skills but from different home countries are attributable to variations in political and economic conditions in the countries of origin at the time of migration excerpt

product choice for a firm selling related products a parimutuel application this paper provides a framework for analysis of product choice by a multiproduct firm selling several products whose demands are interrelated the decision making process of a racetrack racebook regarding the parimutuel wagering products both number and which ones it should supply is illustrated a racetrack racebook is a business entity which offers its patrons the opportunity to wager not only on live horse racing conducted at the racetrack but also on races simulcast to that racetrack from a variety of racetracks from both in state and out of state locations the demands for these wagering products are interrelated and these interrelationships play a key role in determining the number and which ones of these wagering opportunities that will be supplied based on the experience of a specific racetrack racebook these demand functions are estimated econometrically and the role of these interrelated demands in the supply decision is explored an algorithm is developed to search over all possible pr

the dynamics of population growth differential fertility and inequality studies of population growth relative to income distribution from single equation and simultaneous equation models have shown that higher population growth rates increase inequality the reasons for this inequality contain important welfare issues including the fact that different income groups grow at different rates with lower income the fastest the differential fertility of the income groups complicates these issues the lorenz curve has often been used as a foundation of the theory of inequality comparisons and uses cumulative shares of income as a function of cumulative shares of population the mortality rates age of new entrants and the mobility across income groups must be factored in these can be analyzed simultaneously using a multistate life table which describes simultaneous transitions across age groups and states data from brazil was used to test whether increase in the fertility rates of the poor would affect income inequality the results indicate a 100 increase in the fertility of the poor which increases the percentage of poor in the equal fertility case there were decreases in the percent of poor from the original number these results confirm that inequality measures can give conflicting signals and could be inconsistent with real changes in relative welfare analyzing relationships between population growth and inequality is difficult and standard measures are inadequate to test hypotheses about the distribution effects of migration or high fertility it appears to be impossible to differentiate changes in population make up from changes in economic status

the economic analysis of lotteries lotteries determinants of ticket sales and the optimal payout rate this paper considers policy issues arising in the design regulation and taxation of lotteries focusing on the market for an on line lottery game demand determines who buys lottery tickets and in what quantities the design of lotteries affects the terms on which tickets are supplied uk data suggest that its lottery may be priced too high to maximize lottery revenue more revenue might be raised if the proportion of sales allocated to tax and other levies were smaller having established the positive economics of lotteries the paper then assesses their welfare implications pari mutuel lotteries enjoy scale economies and as natural monopolies are invariably run either by government agencies or a regulated licensee i estimate consumer surplus and identify the excess burden that arises from existing over taxation of lotteries the large price elasticity of demand implies that revenue raised from the lottery is raised very inefficiently moreover the demand for lottery tickets is inferior and there is some evidence that such games are contagious and addictive so using lotteries as a vehicle for raising revenue is extremely regressive finally i consider other policy implications induced effects on charitable giving and on other forms of gambling the impact on the government budget perceptions of risk and distributional considerations ian walker

an empirical investigation of the effect of quarterly earnings announcement timing on stock returns this research examines both the association between quarterly announcement timing early or late and the type of news good or bad reported and the relationship between stock returns and timing around the earnings announcement date recent research on announcement timing givoly and palmon 1982 patell and wolfson 1982 kross 1981 and whittred 1980 has provided evidence that delayed announcements of annual earnings more often convey bad news i e lower than expected earnings than do early announcements however we know of no study which has reported evidence of the same phenomenon for quarterly earnings furthermore there is a limited amount of evidence regarding the reaction of market participants to announcement timing while three studies givoly and palmon 1982 kross 1982 and chambers and penman 1984 find that early late announcements are associated with higher lower abnormal returns or high low stock return variability relative to late early announcments only kross 1982 controlled for the sign of the earnings forecast error and none controlled for the magnitude of the earnings forecast error it is well accepted that stock returns are associated with the sign of the earnings forecast error efe since announcement timing is also

inequality and growth why differential fertility matters we argue that inequality and growth are linked through differential fertility and the accumulation of human capital we build an overlapping generations model in which dynasties differ in their initial endowment with human capital growth the income distribution and fertility are endogenous due to a quantiy quality tradeoff families with less human capital decide to have more children and invest less in education when initial inequality is high large fertility differentials lower the growth rate of average human capital since poor families who invest little in education make up a large fraction of the population in the next generation a calibrated model shows that this fertility differential effect is quantitatively important we also provide empirical evidence to confirm the links between inequality differential fertility and growth suggested by the model

intra industry information transfers associated with earnings releases abstract the impact that a firm s earnings releases have on the stock prices of other firms in its industry is examined for an identifiable sub set of firms the results are consistent with a significant information transfer occurring between the earnings release firm and the other firms in its industry this subset is identified by examining the impact of the release on the stock price of the announcing firm the magnitude of this impact is more significant for a sample of firms which have a larger percentage of their revenues in the same line of business as the earnings release firm vis a vis a sample with a lower percentage of their revenues from the same line of business alternative interpretations of the empirical results are also discussed the research findings have implications for information content and market efficiency research and for research on policy issues associated with disclosure regulation

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

lottery markets design micro structure and macro behavior an ace approach abstract an agent based computational modeling of the lottery market is established in this paper to study the design issue in terms of the lottery tax rate as well as the emerging market behavior by using genetic algorithms and fuzzy logic lottery participants are modeled as autonomous agents who may endogenously adapt to exhibit behavioral properties consistent with well noticed behavior of lottery markets three major findings are presented first as anticipated a laffer curve is found in this model nonetheless the laffer curve has a flat top which indicates the non uniqueness of the optimal lottery tax rate second conscious selection behavior is also observed but it becomes weaker as time goes on third for the halo effect we observe exactly the opposite each of these three findings are then compared with available empirical results and the mechanism of genetic algorithms is further examined in light of the anti halo effect
