unit roots and structural change an application to us house price indices this paper employs time series analysis to investigate the price dynamics of the house price indices included in the s p case shiller composite10 index and the validity of the ripple effect following the approach outlined by meen 1999 more specifically the paper first considers the time series properties of the capital gain from the sale of houses that is it examines whether shocks to the capital gain series produce permanent or transitory changes in general the findings lack uniformity and depend upon the assumptions imposed by the testing procedures secondly it considers the time series properties of the ratio of regional house price indices to the composite10 index that is it examines whether shocks to these house price ratios exhibit trend reversion the tests of this ripple effect also display conflicting evidence

β convergence and the cyclical dynamics of uk regional house prices the potential convergence of regional house prices in the uk is examined in contrast to the existing literature which focuses upon stochastic convergence the present paper considers alternative f

differing house price linkages across uk regions a multi dimensional recursive ripple model the aim of this study is to determine the nature of the relationship between house prices of different types of housing across the uk regions we use an autoregressive distributed lag bounds testing approach to determine the long run relationships between house prices as well as an error correction model to estimate the short run dynamics between house prices the data include house prices across the regions of great britain and for new old and modern houses the results suggest that house price shocks ripple across regions although the nature of the relationship varies across housing types we further simulate the impact of house price shocks and reveal a complex structure whereby a house price shock in region a impacts upon prices in other regions which in turn feedback into region a in a recursive ripple

ripple effects in south african house prices this paper analyses the ripple effect of house prices in large medium and small sized houses of five major metropolitan areas of south africa namely cape town durban unicity greater johannesburg port elizabeth uitenhage and pretoria based on available quarterly data covering the period of 1966 q1 to 2010 q1 following the extant literature the issue is contextualised as a unit root problem with one expecting the ratios of metropolitan house price to national house price to exhibit stationarity to an underlying trend value if there is diffusion in house prices using bayesian and non linear unit root tests besides the standard linear tests of stationarity with and without structural break overwhelming support is found for the existence of robust ripple effects also factor analysis conducted suggested that ripple effects originate in cape town for the large housing segment and in durban for the medium and small sized houses

imperfect information and cross autocorrelation among stock prices i develop a model to explain why stock returns are positively cross autocorrelated when market makers observe noisy signals about the value of their stocks but cannot instantaneously condition prices on the signals of other stocks which contain marketwide information the pricing error of one stock is correlated with the other signals as market makers adjust prices after observing true values or previous price changes of other stocks stock returns become positively crossautocorrelated if the signal quality differs among stocks the cross autocorrelation pattern is asymmetric i show that both own and cross autocorrelations are higher when market movements are larger

convergence and spillover of house prices in chinese cities abstractthe issue of house price convergence in 34 chinese cities is investigated we augmented the convergence model with contemporaneous spatial dependence in house prices and found that price convergence and positive spatial spillover are both present we explicitly addressed the endogeneity problem by introducing a bayesian instrumental variable setup which was estimated with particle filtering techniques from a growth poles perspective the empirical evidence indicates that the spread effect in regional house prices outweighs the backwash effect the identified positive spatial spillover has two effects on the growth of house prices in chinese cities first the spillover elevates the trajectories of the steady state growth paths of house prices second the spillover narrows the gaps between the growth paths of house prices in neighbouring cities shocks to the socio economic variables of a city generate their own effects on domestic house prices that dominate the effects arising from cross city p

information technology and time based competition in financial markets this paper studies time based competition in imperfect securities markets linking it investment decisions information processing delays and trading strategies at the it investment stage traders trade off the cost of it against their anticipated trading profits at the trading stage each trader devises a trading strategy based on his new information while taking into account the impact of both his own trades and those of other traders in the market our results illustrate how traders react to market imperfections due to trading costs and information processing delays and how superior traders convert a timeliness advantage into higher trading profits they also shed light on the relationship between the price adjustment process and traders information processing delays timeliness imposes an interesting structure on trader competition traders with longer information processing delays trade less frequently submit smaller orders and enjoy lower profits per trade our analysis of traders it investment decisions demonstrates how factors such as it costs number of traders and the frequency and nature of new information affect the level of it investments we further illustrate how improved it infrastructure translates into competitive advantage

funding liquidity and equity liquidity in the subprime crisis period evidence from the etf market using index and financial exchange traded funds etfs this study explores the relation between funding liquidity and equity liquidity during the subprime crisis period our empirical results show that a higher degree of funding illiquidity leads to an increase in bid ask spread and a reduction in both market depth and net buying imbalance such findings indicate that an increase in funding liquidity can improve equity liquidity with a stronger effect for the financial etfs than for the index etfs our study provides a better overall understanding of the effect of the liquidity supplier funding constraint during the subprime crisis period

how trading institutions affect financial market performance some laboratory evidence i introduction trading institutions vary considerably across contemporary financial markets 1 but most can be classified into one of two basic types the continuous double auction da allows traders to submit public offers to buy or to sell and to accept other traders offers at any moment in time the double auction institution offers immediacy but non uniform transaction prices the other basic trading institution the clearinghouse ch gathers offers and clears them at a unified price at a pre specified time it sacrifices immediacy for uniform transaction prices 2 the two types of institutions have co existed and evolved for centuries but now are emerging in new electronic versions market participants and policy makers would like to know which institution or variant or combination is most efficient but theoretical and empirical work to date provides little guidance this paper reports on a series of laboratory asset markets experiments designed to compare variants of the double auction and clearinghouse trading institutions the markets are small usually with eight or nine traders but the traders are profit motivated and experienced with the trading institutions the traded asset has uncertain market value and traders receive useful but inconclusive private information they can only learn the asset s true value during the course of trade laboratory markets offer several advantages for empirical study of financial market institutions first private information is observable even controllable in the laboratory and therefore the investigator can directly measure market efficiency 3 second the complexity of the environment can be varied systematically in the laboratory and its effects on market performance can be separated from the effects of the market institution and other forces finally the market institution itself is controllable in the laboratory so it is possible to make valid causal inferences on how the market institution shapes market performance i begin with a survey of relevant literature and other preliminaries in the rest of this section section ii outlines the laboratory procedures the creation of trading environments of varying complexity the electronic implementation of the clearinghouse and double auction trading institutions the computation of theoretical benchmark prices and allocations and the measurement of market performance section iii collects the results following an illustrative account of a double auction trading period and a clearinghouse trading period i use descriptive statistics to summarize market performance in each of the thirty nine experiments the main conclusions are based on statistical comparisons of market performance across alternative market institutions the clearinghouse institution does surprisingly well it delivers greater market depth than the double auction discovers prices at least as efficiently and produces final allocations almost as efficient as the double auction the main institutional variants examined in this paper concern the amount of information made public regarding order placement orderflow the data suggest that public display of the orderflow enhances double auction efficiency but may impair clearinghouse efficiency a study of trading volume shows higher volume in the double auction in both institutions volume increases when important private news arrives and when the trading period is about to end the paper concludes with a brief summary and discussion of the results a companion paper friedman 1991 considers the effects of awarding various privileges to some but not all traders copeland and friedman 1987 1991 provide useful background information on laboratory procedures and computerized double auction markets instructions for the current experiments are available on request the need for empirical work a skeptic might argue that empirical work is unnecessary the mere fact that the double auction and clearinghouse institutions both persist in major financial markets implies that both are highly efficient because a more efficient institution would displace less efficient institutions

trading halts and market activity an analysis of volume at the open and the close this paper analyzes how the daily opening and closing of financial markets affect trading volume we model the desire to trade at the beginning and end of the day as a function of overnight return volatility nyse data from 1933 88 indicate that closing volume is positively related to expected overnight volatility while volume at the open is positively related to both expected and unexpected volatility from the previous night we interpret the symmetric response of trading at the open and the close to expected volatility as being due to investor heterogeneities in the ability to bear risk when the market is closed this desire of investors to trade prior to market closings indicates a cost of mandating marketwide circuit breakers

systemic co jumps abstract the simultaneous occurrence of jumps in several stocks can be associated with major financial news triggers short term predictability in stock returns is correlated with sudden spikes of the variance risk premium and determines a persistent increase decrease of stock variances and correlations when they come along with bad good news these systemic events and their implications can be easily overlooked by traditional univariate jump statistics applied to stock indices they are instead revealed in a clearly cut way by using a novel test procedure applied to individual assets which is particularly effective on high volume stocks

trading mechanisms and stock returns an empirical investigation this paper examines the effects of the mechanism by which securities are traded on their price behavior we compare the behavior of open to open and close to close returns on nyse stocks given the differences in execution methods applied in the opening and closing transactions opening returns are found to exhibit greater dispersion greater deviations from normality and a more negative and significant autocorrelation pattern than closing returns we study the effects of the bid ask spread and the price adjustment process on the estimated return variances and covariances and discuss the associated biases we conclude that the trading mechanism has a significant effect on stock price behavior

the convergence of regional house prices in the uk the ripple effect hypothesis implies a long run convergence of regional uk house prices however despite many authors believing in the existence of such an underlying constancy statistical evidence has yet to be presented supporting this implication in this paper an alternative approach is proposed to analyse regional house price ratios in contrast to the findings of previous studies application of this new procedure results in the detection of widespread convergence of house prices in a number of regions of the uk the results suggest that the failure of previous analyses to uncover convergence is due to an underlying asymmetry in the adjustment process being ignored interestingly the form of asymmetry detected varies between regions while regions in the south east experience faster convergence following downswings in prices other regions exhibit more rapid convergence following increases in prices

pairwise convergence of district level house prices in london this paper investigates the long run convergence of district level house prices in greater london using the recently developed pairwise approach this methodology allows for unit root tests to be conducted on all n n 1 2 possible pairs of house price differentials across the n boroughs of london thus avoiding the need to choose a base borough of reference or the regional average as the benchmark it also permits the estimation consistently of the proportion of the pairs that are stationary and convergent using hm land registry house price data for 33 inner and outer london boroughs over the period 1996q1 2009q2 no overall multidistrict long run convergence is found some evidence of district level segmentation of house prices in greater london is found with the sub group of the boroughs contiguous to the city of london district and the wider central sub market emerging as the clubs with the highest rate of convergence

stock volatility and margin trading abstract this study examines additions of otc issues to the list of marginable securities and tests the hypothesis that margin trading destabilizes prices and contributes to volatility no detrimental effects are found instead evidence suggests that margin eligibility increases the flow of information and enhances depth though volumes are 30 larger volatility and noise decrease with the inception of margin trading further margin eligibility is valuable increases in value of 2 occur upon the announcement of eligibility analysis of a small sample of margin eligibility revocations provides no evidence that tightening margin restrictions reduces volatility

margin regulation and stock market volatility using daily and monthly stock returns we find no convincing evidence that federal reserve margin requirements have served to dampen stock market volatility the contrary conclusion expressed in recent papers by hardouvelis 1988a b is traced to flaws in his test design we do detect the expected negative relation between margin requirements and the amount of margin credit outstanding we also confirm the recent finding by schwert 1988 that changes in margin requirements by the fed have tended to follow rather than lead changes in market volatility after 55 years stock market margin requirements are again a source of controversy the securities and exchange act of 1934 transferred to the federal reserve system the authority exercised previously by the new york stock exchange and other private sector exchanges to set the minimum margins i e down payments that securities brokers and dealers subsequently expanded to all lenders must require of customers purchasing common stocks on credit the transfer of authority reflected the view widely held at the time that the low initial margins set by the exchanges had fueled the stock market boom of the 1920 s and that the frenzied liquidation of shares in response to margin calls had accelerated the crash in october 1929 supposedly dragging the economy down with it congress hoped that timely raising of margin requirements by the monetary authorities might dampen speculative excesses before they raged out of control or in today s terms that margin controls might reduce market volatility what the federal reserve has done since then with its margin setting authority can be seen from figure 1 which shows the time paths both of margins and one measure of market volatility from october 1934 to december 1987 margin requirements were set initially at 45 percent raised to 55 percent during the boomlet of 1936 and then cut back to a low of 40 percent after the sharp stockmarket break in the autumn of 1937 the requirement stayed at that level for the remainder of the 30 s and most of the war years but was stepped up sharply as the war drew to a close reaching 100 percent i e all cash no borrowing for most of 1946 changes were frequent over the next two and a half decades

trader leverage and liquidity does trader leverage drive equity market liquidity we use the unique features of the margin trading system in india to identify a causal relationship between traders ability to borrow and a stock s market liquidity to quantify the impact of trader leverage we employ a regression discontinuity design that exploits threshold rules that determine a stock s margin trading eligibility we find that liquidity is higher when stocks become eligible for margin trading and that this liquidity enhancement is driven by margin traders contrarian strategies consistent with downward liquidity spirals due to deleveraging we also find that this effect reverses during crises

intraday price reversals for index futures in the us and hong kong abstract we observe intraday price reversals following large price changes at the opening of the s p 500 futures market and the hsi futures market we note that the magnitude of subsequent price reversals is positively related to the initial price changes and that the price reversals are not caused by a bid ask spread or by panic among investors we also note that such price reversals can be exploited to give rise to profitable opportunities after transaction costs even though these may not be very significant this study shows that investor overreaction may be a universal phenomenon and irrational investor behavior like overreaction may also exist among groups of sophisticated investors

consolidation fragmentation and market performance this paper studies the impact of market consolidation or fragmentation on its performance examining four alternative models of exchange a consolidated clearing house fragmented clearing houses a monopoly dealer market and an interdealer market the effects of the market mechanism on the expected quantity traded the price variance faced by individual traders the quality of market price signals the expected gains from trade and the exchange implementation costs are studied

convergence trading with wealth effects an amplification mechanism in financial markets abstract i study convergence traders with logarithmic utility in a continuous time equilibrium model in general convergence traders reduce asset price volatility and provide liquidity by taking risky positions against noise trading however when an unfavorable shock causes them to suffer capital losses thus eroding their risk bearing capacity they liquidate their positions thereby amplifying the original shock in extreme circumstances this wealth effect causes convergence traders to be destabilizing in that they trade in exactly the same direction as noise traders this situation is consistent with the near collapse of long term capital management in 1998

the firm size relation and stock market responses to post 1962 changes in federal reserve margin levels evidence from an exhaustive sample of exchange listed firms abstract an analysis of the effects of changes in us federal reserve stock market margin requirements on the return characteristics of firms of differing equity values suggests that the price changes observed for smaller firms following margin announcements are of considerably greater magnitude than the reactions observed for the s p composite index

a disaggregated analysis of asymmetrical behaviour in the uk housing market potential asymmetrical adjustment in uk house prices is considered the present analysis extends previous research in a number of crucial ways first a seminal examination of asymmetry in regionally disaggregated uk house prices is undertaken secondly data are examined which are further disaggregated according to the age or vintage of the housing stock however the major development concerns the application of a non parametric testing approach to detect cyclical asymmetry in contrast to previously employed tests in the economics literature the triples test employed possesses high power and is not sensitive to outliers it is found that extensive asymmetry is present in uk house prices with cyclical peaks typically being greater in magnitude than corresponding troughs the implications of these findings for the comparison and construction of economic theories of the housing market the specification of econometric models and the construction and implementation of economic policy are noted

initial margin policy and stochastic volatility in the crude oil futures market this article examines the relationship between the volatility of the crude oil futures market and changes in initial margin requirements to closely match changes in futures market volatility with the corresponding changes in margin requirements we infer the volatility of the futures market from the prices of crude oil futures options contracts using a mean reverting diffusion process for volatility we show that changes in margin policy do not affect subsequent market volatility

regional house price convergence in spain during the housing boom the aim of this paper is to identify convergence clubs in house prices among spanish regions over the period 1995 q1 to 2007 q4 and to investigate which factors are responsible for club formation employing a novel regression based convergence test proposed by phillips and sul 2007 we find that regional house prices do not converge to a common trend which confirms the existence of some degree of segmentation in the spanish housing market the research results support the existence of convergence clubs indicating that spanish regions form four separate groups that converge to different house price levels results of an ordered logit model suggest that differences in population growth size of the rental market initial house supply and geographical situation have played a crucial role in determining club membership

the price effect of option introduction this paper examines the price effect of option introduction from 1974 to 1980 the introduction of individual options causes a permanent price increase in the underlying security beginning approximately three days before introduction the price effect appears to be associated with introduction and not announcement throughout the sample period excess returns volatility declines with option introduction systematic risk is unchanged there is a positive relation between the price increase and a measure of activity in the options market copyright 1989 by american finance association

transitory price changes and price limit rules evidence from the tokyo stock exchange we compare the volatility of 24 hour returns computed from the opening and closing prices of a diverse sample of tokyo stock exchange tse stocks we find that volatility at the open is greater than volatility at the close only for the most actively traded tse stocks daytime and overnight return covariances suggest that the volatility patterns are explained by the effect of implicit bid ask spreads at the open and partial price adjustment at the close both of which are related to the intensity of trading our results challenge the view that open to open returns are more volatile than close to close returns for stocks in general and are consistent with the hypothesis that tse price limit rules have a significant impact on the dynamics of security prices

a new perspective on the ripple effect in the uk housing market comovement cyclical subsamples and alternative indices an alternative perspective is provided on the existence of a ripple effect in the uk housing market in contrast to previous studies the analysis involves consideration of information on the changes in house prices to which the hypothesis of house price diffusion posited by the ripple effect relates rather than their levels in an examination of changes in house prices in london relative to other regions of the uk directional forecasting methods are employed to establish the extent of the relationship between geographical proximity and comovement across the three month window provided by quarterly data consequently the analysis provides a direct examination of the ripple effect which refers to changes in prices rather than the convergence of levels which has become a feature of the empirical literature the literature is extended further by both the application of dating techniques to perform the analysis across cycles and phases of cycles recovery and recessionary periods in the uk housing market

spillover effect between the regional and the national housing markets in the uk tsai i c spillover effect between the regional and the national housing markets in the uk regional studies this study uses regional and national data from the uk housing market to analyse the spillovers between these markets and to test whether a ripple effect exists in uk housing prices cross market return spillovers are determined by performing spillover indices an analysis of the direction and magnitude of return spillovers can be used to discriminate the transmission mechanism of information between the regional and the national housing markets over different areas and different time spans empirical findings indicate that the difference in housing prices between the northern and southern regions of the uk will increase each time a new financial crisis occurs

measurement effects and the variance of returns after stock splits and stock dividends this article examines the relation between two factors affecting stock returns the bid ask spread and price discreteness and the increase in return variance after ex dates of stock splits and stock dividends controlling for these effects the variance of daily returns still increases significantly the variance of weekly returns also increases significantly and the variance of returns for a control sample of nonsplitting firms shows no significant increase variance ratio tests show that bid ask errors are small for these stocks and therefore cannot explain the large increase in variance spreads and price discreteness do not explain increased variance after stock distributions article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

marginal tax rates evidence from nontaxable corporate bonds a note this study offers an alternative method of calculating marginal personal tax rates through the pairing of nontaxable industrial development and pollution control and taxable corporate bonds this procedure is shown to produce matched bond pairs that are comparable two hundred pairs of bonds are examined from the second quarter of 1973 through the second quarter of 1983 testing of the marginal tax rate relationships indicates that the marginal personal tax rate is less than the corporate statutory tax rate the examination of the relative pricing of taxable and nontaxable bonds provides an estimate of the marginal tax rates of bondholders who are indifferent between taxable and nontaxable bonds see for example gordon and malkiel 1 trczinka 6 and skelton 4 typically these implied marginal tax rates are calculated by comparing yield indices of taxable corporate bonds and nontaxable municipal bonds a potential problem with this method pointed out by trczinka 6 is that municipal and corporate bonds may not be of the same risk requiring some adjustment in the calculation another problem with this method is that the bond yield indices are computed from a sample of outstanding bonds introducing a potential yield to maturity bias associated with discount bonds skelton 4 an alternative procedure for calculating implied marginal tax rates is employed in this paper which avoids the problems of differential risks and the potential yield to maturity bias for discount bonds implied tax rates are calculated from pairs of newly issued bonds where each pair consists of one nontaxable corporate bond a tax exempt industrial development or pollution control bond and one taxable corporate bond 1 since only newly issued bonds are used in the computations the bias associated with capital gains and losses is avoided this study is organized into the following sections section i describes the data and the collection procedure the resultant implied marginal rates are presented in section ii summarizing and concluding remarks are provided in section iii

spatial dynamics of the housing market an interurban perspective a major unproven hypothesis in housing economics is that regional ripple effects are caused by household migration between regions this paper examines household migration and price ripples at the level of local housing markets driven partly by the fact that such migration linkages are likely to be more pronounced between local rather than regional housing markets following a review of regional housing market studies several hypotheses linking the existence of lead lag relationships and cointegration with the scale of migratory linkages between local housing market areas lhmas are proposed using private housing transactions data for strathclyde a sub region of scotland the paper identifies two clusters of lhmas that differ in terms of their migratory linkages with glasgow the hypothesised leading housing market of the sub region tests for lead lag relationships and cointegration confirm the link between migration and house price changes

term structure effects on default risk premia and the relationship of default risky tax exempt yields to risk free taxable yields a note abstract the behavior of the default risk premium on bonds has caught the attention of many researchers some researchers have analyzed how default risk premia may vary with maturity it has been suggested that default risk premia are independent of maturity however recent research by rodriguez 1988 shows this to not hold for nonpar taxable bonds this research shows that the shape of the underlying term structure affects default risk premia for even par bonds in a systematic way furthermore the maturity dependent variation in equilibrium tax rates has a strong impact upon default risk premia behavior where equilibrium tax rates are derived from comparisons of taxable and tax exempt bonds the inclusion of the shape of the underlying term structure also has very important implications for the relation between taxexempt yields and taxable yields the slope and intercept terms of the relation between taxexempt and taxable yields are clearly dependent upon maturity a fact which has not been recognized before

tax management and investment strategies of property liability insurers abstract the tax reform act tra of 1986 reduced the incentives for institutional investors to participate in the tax exempt bond market this paper develops a model of profit maximization incorporating the tra provisions applicable to property liability pl insurers the theory predicts that pl insurers will use underwriting losses to shelter taxable investment income and invest the balance of their portfolios in tax favored securities our empirical evidence reveals that insurers continued to invest in tax exempts following the tra suggesting that implicit tax rates are low enough to attract insurers into the long term tax exempt market however insurers reduced the proportions of income derived from tax exempt interest and dividends following the tra

relative risk in municipal and corporate debt the yields of municipal bonds and corporate bonds are often compared the ratios of municipal bond yields to corporate bond yields are thought by many to be indicative of the marginal tax bracket of the marginal holder of the bonds if for example the ratio is 60 the implication is that an investor in the fortypercent tax bracket will be indifferent between the fully taxed corporate and the fully tax exempt municipal this assumes that the two bonds are currently selling at par such comparisons have attracted increased attention since the publication of merton miller s seminal debt and taxes in this work miller indirectly suggests that the marginal tax bracket at work across tax exempt and taxable bonds is equal to the corporate tax rate while the ratio of yields seems to indicate that this is true for short term bonds the yields of long term taxexempts seem too high relative to long term taxables to confirm miller s hypothesis implicit in these comparisons and the conclusions drawn from them is the tenuous notion that the compared bonds are identical except for the taxability of the coupon for example some authors have questioned whether municipals and corporates are equally risky see trzcinka 1982 the purpose of this paper is to present preliminary evidence on the relative riskiness of the two classes of bonds

tax induced intra year patterns in bonds yields the ratio of the yields on short term tax exempt and taxable bonds exhibits a sawtooth pattern that is consistent with the impacts of tax deferments from dates on which interest payments are received to dates on which the resulting tax payments are paid the effect of the tax deferment at turns of calendar years does not differ appreciably from the effect at the turn of any other tax quarter investors with tax payment schedules that differ from that of the investor that is indifferent between investing in taxable and tax exempt bolnds may benefit from tax related timing strategies for investing in these bonds issuers may benefit from tax related timing strategies for scheduling interest payments

further evidence on the firm size relation and stock market responses to changes in federal reserve margin levels the virtually monotonic firm size price reactions observed following changes in u s federal reserve market margin requirements over the post 1962 period provide dramatic new evidence in support of the hypothesis that changes in margin levels are associated with changes in security return behavior variance tests of the 1970 and 1971 margin decreases also produce evidence consistent with this hypothesis

convergence and divergence in british housing space abstractthe degree of convergence that exists among british house prices is an open question inferences vary with the method applied and periods considered using the rank of the cointegrating matrix among four decades of regional data two contiguous groups of regions are revealed these super regions have some common members through which price changes are transmitted from south to north with london found to be deviating from the south east neither it nor the uk are likely to be indicative of the regional series of the south of england

market behavior in a clearing house one of the most fundamental market mechanisms is the clearing house where orders are accumulated over time and the market is cleared periodically the issue addressed in this study is the statistical behavior of the market under this neutral mechanism in the framework of a tractable stochastic model which captures the underlying uncertainties and indivisibilities in the demand and supply schedules applying renewal theory we derive closed form results for the behavior of prices and quantities and pursue the implications of the possibility of no trade and the multiplicity of market clearing prices

price discovery in auction markets a look inside the black box opening mechanisms play a crucial role in information aggregation following the overnight nontrading period this article examines the process of price discovery at the new yorkstockexchange single price opening auction we develop a theoretical model to explain the determinants of the opening price and test the model using order level data we show that the presence of designated dealers facilitates price discovery relative to a fully automated call auction market this is consistent with specialists extracting information from observing the evolution of the limit order book in addition the specialist s opening trade reflects noninformational factors such as price stabilization requirements

margin requirements and stock market volatility abstract it has long been recognized that margin requirements through leverage affect the volume of speculative activity controlling speculative behavior is one approach to inhibiting overvaluation in stocks and reducing the potential for a precipitate price decline fueled by the involuntary selling that stems for example from margin calls

long memory and fractional integration in the housing price series of london and paris this article deals with the analysis of house price indexes from a long range dependence viewpoint in particular it estimates the fractional differencing parameter in the london and paris house price series recognizing in some cases the potential seasonality and allowing for breaks in the data moreover it analyses the stability of the parameters across the sample period examined it is concluded that the series are nonstationary but mean reverting in some cases and very persistent in others policy implications are derived

banks firms and the relative pricing of tax exempt and taxable bonds abstract the traditional analysis of the relative pricing of tax exempt and taxable debt is a habitat theory of the term structure of interest rates in the traditional analysis the preferences of investors for particular maturities of debt lead to unique pricing relations at every point on the yield curve which are indicative of investor marginal tax brackets recent work by fama 1977 suggests that banks are potential arbitrageurs across tax exempt and taxable bond markets which force a particular equilibrium on the pricing of short term bonds miller 1977 suggests that the choice of debt or equity financing by firms in the aggregate forces a similar equilibrium on the pricing of all tax exempt and taxable bonds this paper exploits the institution of regulation q and its effects on the banking system to bring evidence to bear on the predictions of these three models

municipal debt and marginal tax rates is there a tax premium in asset prices we study the marginal tax rate incorporated into short term municipal rates using municipal swap market data using an affine model we identify the marginal tax rate and the credit liquidity spread in 1 week tax exempt rates as well as their associated risk premia the marginal tax rate averages 38 0 and is related to stock bond and commodity returns the tax risk premium is negative consistent with the strong countercyclical nature of after tax fixed income cash flows these results demonstrate that tax risk is a systematic asset pricing factor and help resolve the muni bond puzzle

the irrelevance of margin evidence from the crash of 87 following the crash of 1987 one contentious regulatory issue has been whether margin activity exacerbated the decline in equity values we contrast the crash behavior of nasdaq securities eligible for margin trading with the behavior of ineligible ones consistent with the hypothesis that margin eligible securities were more frequently subjected to margin calls and forced sales we find that abnormal volumes were uniformly larger for eligible securities however there is no evidence that this activity provoked additional price depreciation margin eligible securities actually fell by one percent less than the ineligible securities over the period

market quality changes in the london stock market this paper examines the impact that the introduction of a closing call auction had on market quality at the london stock exchange using estimates from the partial adjustment with noise model of amihud and mendelson amihud y mendelson h 1987 trading mechanisms and stock returns an empirical investigation journal of finance 42 533 553 we show that opening and closing market quality improved for participating stocks when we stratify our sample securities into five groups based on trading activity we find that the least active securities experience the greatest improvements to market quality a control sample of stocks are not characterized by discernable changes to market quality

is there long run convergence among regional house prices in the uk this paper investigates the long run convergence of regional house prices in the uk existing studies have failed to reach a consensus on whether or not regional house prices exhibit long run convergence with each other the application is proposed of a new test involving unit root testing of the first principal component based on regional national house price differentials using mix adjusted quarterly data for 1973 2006 it is found that the first principal component is stationary this suggests that all uk regional house prices are driven by a single common stochastic trend further analysis suggests that those regions that are more distant from london exhibit the highest degrees of persistence with respect to deviations in house price differentials

short sales and speed of price adjustment evidence from the hong kong stock market abstract we present empirical evidence that short sales contribute to market efficiency by increasing the speed of price adjustment to not only private public firm specific information but also market wide information shortable stocks are characterized by weaker trade continuity and stronger quote reversals they adjust faster to new information than non shortable counterparts these findings remain robust even in an up market condition in which short sales are not binding the amount of information incorporated in each trade is also significantly higher for shortable than non shortable stocks in both up and down market conditions after controlling for firm size trading volume liquidity price and option trading short sales stand out as one of the significant factors that speed up the price adjustment

testing for long run convergence across regional house prices in the uk a pairwise approach this article tests for stochastic convergence in uk regional house prices using the recently developed pairwise approach this approach allows for unit root tests to be conducted on all n n 1 2 possible pairs of house price differentials across n regions in the uk thus avoiding the need to choose a base region or alternative national figure as the benchmark using mix adjusted house price data from 1973 q4 to 2008 q4 the main finding is that there is no evidence of long run convergence among regional house prices or of an equilibrium relationship towards which uk regional house prices have a tendency to gravitate

price adjustment delays and arbitrage costs evidence from the behavior of convertible preferred prices price adjustment delays occur between in the money convertible preferred stock prices and common stock prices convertible preferred prices systematically deviate from the prices predicted from their conversion relations with common stocks the price predictability stems from price changes in the underlying common stocks leading the price changes in the convertible preferred stocks by up to nine hours cross sectionally about 70 percent of the variation in the unsigned size of the price deviations is explained by proxies for costs of arbitrage

cross sectional dependence and problems in inference in market based accounting research this paper provides a framework and some empirical evidence to evaluate the seriousness of problems in inference that arise in stockreturn based studies when the data are cross sectionally dependent the study is motivated on the grounds that statistical procedures designed to address such problems are often infeasible and even when they can be implemented they sometimes introduce other more serious difficulties thus researchers have frequently adopted an approach that ignores the cross sectional dependence e g ordinary least squares ols the objective of this paper is to help identify the contexts in which ignoring the dependence would lead to serious misstatement of significance levels cross sectional dependence in stock returns data is likely to exist when at least some of the returns are sampled from common time periods this would be the case in all studies of the reaction of stock prices to a

the trading decision and market clearing under transaction price uncertainty this paper models an individual s trading decision given 1 his her demand function to hold shares of an asset 2 his her expectation on what the market clearing price will be and 3 the design of the market which determines how orders will be translated into trades the particular market design we consider is the batched trading periodic call regime assuming investors are distributed according to their propensities to hold shares we model the aggregation of orders to obtain market clearing values of price and volume and to show the way in which with trading friction these solutions differ from pareto efficient values the importance of this analysis for various issues concerning market design is noted when markets are not frictionless and transaction prices are uncertain the act of trading requires analysis this paper models an individual s trading decision in secondary financial asset markets in so doing we study the order flow as an endogenous part of the system we show how given an underlying demand curve the trader will choose an optimal price quantity order to transmit to the market and we model the aggregation of orders to obtain market clearing values for price and volume these models are used to show the way in which the prices and trading volume established on the market will in general differ from their pareto efficient values much of the microstructure literature that studies the behavior of transaction prices in a nonfrictionless market has assumed that orders are generated by some exogenously given stochastic process this has been true for instance in the

the relevance of margin regulations note margin credit was singled out for selective credit control in 1934 by the securities exchange act sea this act directed the federal reserve board to regulate security credit so as to prevent the excessive use of credit in the purchase or carrying of securities the principal objectives of the sea were 1 to protect investors from speculative losses 2 to prevent the speculative securities markets from absorbing credit away from productive commercial and agricultural uses and 3 to inhibit security price fluctuations due to credit financed security purchases to date there has been little research into the effectiveness of margin regulations in attaining the objectives of the sea 2 one noteworthy exception is a paper by luckett 1982 which analyzes the efficacy of margin requirements in influencing the investor s degree of personal leverage and risk exposure however luckett s analysis leaves unanswered the impacts of changes in margin requirements on firm valuation security returns uncertainty and the allocation of credit in the economy in this paper modern finance theory is employed to analyze some of these effects we conclude that corporations will take actions so as to offset at least in part the impacts of changes in margin restrictions on personal leverage and that the effects of margin requirements are generally inconsistent with the objectives of the sea reformers

trading and returns under periodic market closures this paper studies how market closures affect investors trading policies and the resulting return generating process it shows that closures generate rich patterns of time variation in trading and returns including those consistent with empirical findings 1 u shaped patterns in the mean and volatility of returns over trading periods 2 higher trading activity around the close and open 3 more volatile open to open returns than close to close returns 4 higher returns over trading periods than over nontrading periods 5 more volatile returns over trading periods than over nontrading periods it also shows that closures can make prices more informative about future payoffs we model a competitive stock market with periodic closures in which investors trade for both allocational and informational reasons we use the model to study how market closures intrinsically affect investors trading behavior and the return generating process the purpose of this analysis is to increase our understanding of the time variation in security trading and returns that are associated with regular market closures such as the intraday and intraweek patterns in stock returns volatility and trading volume we consider a stock market in which the exogenous information flow is homogeneous over time and the market closes periodically when the market is open investors trade the stock either to rebalance their overall portfolio of assets which also includes other illiquid assets or to speculate on future stock payoffs using their private information in particular investors adjust their asset portfolio by trading the stock in order to hedge the risk of illiquid assets we refer to these trades as hedging trades and those motivated by private information as speculative trades when the market is closed hong is from the graduate school of business stanford university and wang is from the sloan school of management massachusetts institute of technology and nber the authors thank jennifer huang for programming assistance and an anonymous referee for many valuable suggestions they also thank glenn ellison john heaton craig holden andrew lo steve slezak jeremy stein rene stulz the editor the nber asset pricing lunch group and par

default risk cannot explain the muni puzzle evidence from municipal bonds that are secured by u s treasury obligations fama 1977 and miller 1977 predict that one minus the corporate tax rate will equate after tax yields from comparable taxable and tax exempt bonds empirical evidence shows that long term tax exempt yields are higher than theory predicts two popular explanations for this empirical puzzle are that relative to taxable bonds municipal bonds bear more default risk and include costly call options i study u s government secured municipal bond yields which are effectively default free and nonmalleable these municipal yields display the same tendency to be too high i conclude that differential default risk and call options do not explain the municipal bond puzzle article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

an examination of stock market return volatility during overnight and intraday periods 1964 1989 this paper examines the variance of hourly market returns during 1964 89 results indicate that return volatility falls from the opening hour until early afternoon and rises thereafter and is significantly greater for intraday versus overnight periods market variance is also shown to change significantly over time rising after nasdaq began in 1971 rising after trading in stock options began in 1973 falling after fixed commissions were eliminated in 1975 rising after trading in stock index futures was introduced in 1982 and falling after margin requirements for stock index futures became larger in 1988 copyright 1990 by american finance association

synchronisation and commonalities in metropolitan housing market cycles this paper examines the degree of commonalities present in the cyclical behaviour of the eight largest metropolitan housing markets in australia using two techniques originally proposed in the business cycle literature we firstly consider the degree of synchronisation present and secondly decompose the series into their permanent and cyclical components both empirical approaches reveal similar results sydney and melbourne are closely related to each other and are relatively segmented from the smaller metropolitan areas in contrast there is substantial evidence of commonalities in the cyclical behaviour of the remaining cities especially those on the eastern and southern coasts of australia

price formation on stock exchanges the evolution of trading within the day prior analyses of prices of the nyse and other exchanges find that transitory price volatility is greater at the open of trading than at the close we extend this line of research by using 40 years of hourly dow jones 65 composite price index data to estimate transitory volatility throughout the trading day our results indicate that transitory volatility steadily declines during the trading day we find a similar intraday decline in transitory volatility for a 2 1 2 year sample of the individual firms in the dow jones 30 industrials index the results are consistent with the hypothesis that trading aids price formation and do not support the argument that particular trading mechanisms are the source of greater volatility at the open of trading article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

animal spirits margin requirements and stock price volatility a simple overlapping generations model is used to characterize the effects of initial margin requirements on the volatility of risky asset prices investors are assumed to exhibit heterogeneous preferences for risk bearing the distribution of which evolves stochastically across generations this framework is used to show that imposing a binding initial margin requirement may either increase or decrease stock price volatility depending upon the microeconomic structure behind fluctuations in economy wide average risk bearing propensity the ambiguous effect on volatility similarly arises when the source of heterogeneity is noise trader beliefs beyond their prudential functions the effects of initial margin requirements on securities markets are not well understood many have argued based upon empirical findings that the level of margin requirements has no discernable impact on stock price behavior nevertheless the view that high margin requirements dampen speculative excesses and reduce excess price volatility remains popular the simultaneous existence of such views highlights the uncertainty surrounding this issue in fact there exists no rigorously articulated theory of the interaction between initial margin requirements and stock prices and their returns characteristics in this paper we construct a simple dynamic model useful for characterizing the effects of initial margin requirements on security prices and returns to analyze the impact of margins we introduce investor heterogeneity into an otherwise simplified overlapping generations olg economy 2 the olg models are constructed so that each generation displays heterogeneous preferences or beliefs the distribution of which evolves stochastically across generations in each of two heterogeneous taste models we consider there are two types of agents one of which is more risk tolerant than the other in one model the

sterling s relationship with the dollar and the deutschemark 1976 89 this paper evaluates the linkages between bilateral exchange rates using a time varying parameter model which can be estimated using the kalman filter the technique solves many of the statistical problems which arise when ordinary least squares is used to estimate currency correlation applying the technique to the dollar sterling dm sterling and dm dollar bilateral exchange rates the results suggest a market weakening strengthening of sterling s relationship with the dollar dm since the mid 1970s additionally these currency linkages are shown to have undergone a number of regime shifts suggesting that the timing of the weakening of the dollar sterling relationship is different to that proposed by previous studies copyright 1991 by royal economic society

the feasibility of an index contingent trading mechanism auction or call trading systems are used in many stock exchanges an essential problem in the application of these systems is that orders in one security cannot be conditioned on prices of other securities this paper proposes and analyzes the feasibility of an index contingent trading system in this system limit orders may be conditioned on an index any weighted average of the security prices that is determined simultaneously with the prices in addition to the asset price without any assumptions about traders behavior it is shown that under a reasonable restriction on the structure of the limit orders there is a unique solution vector of prices to any set of orders in all securities moreover the paper presents a quick and simple algorithm that converges to the solution this algorithm is based on an extension of the current mechanisms therefore it can be implemented easily in any computerized auction system

on the effectiveness of the federal reserve s margin requirement a portfolio theoretic model of the optimal margin account is developed it is argued that the federal reserve s goal in setting the margin requirement is to influence investor equity ratios using the average equity ratio as the dependent variable and the arguments of the model as independent variables an empirical model is estimated it is concluded that the margin requirement is an effective regulatory tool the state of the art with respect to the question of the effectiveness of the federal reserve s initial margin requirement is anomalous notwithstanding the profession s current obsession with the tools of monetary policy there are only two extant studies dealing with the central issue the effect of changes in regulation t on margin credit extended by securities dealers 1 moreover the two studies that do exist reach opposite conclusions one that the margin requirement is effective the other that it is not both studies are quite dated the first that of bogen and krooss 1 examined the behavior of various stock market series in the six months before and after a change in the margin requirement one of their findings was that increases in customer net debit balances always either slowed or reversed when the margin requirement was raised and conversely for decreases in the margin requirement on the basis of this evidence bogen and krooss concluded that changes in the margin requirement have to date 1960 achieved the primary objective of limiting and regulating the volume of security credit 1 p 157 however bogen and krooss also found that the quantitative behavior of customer net debit balances seemed to bear no relation to the size of the change in the margin requirement

tax clienteles and optimal capital structure under uncertainty this article demonstrates that investors heterogeneous tax status implies that they value bonds differently at the margin due to asymmetric personal taxes high risk bonds generate a higher amount of taxable income than low risk bonds and are therefore held by investors in low tax brackets in such a setting firms can increase their value by choosing a capital structure that attracts a particular bondholder clientele the author analyzes how bondholder clienteles change as the uncertainty about a bond s final payoff is resolved over time and shows how tax clientele effects influence firms capital structure decisions copyright 1990 by the university of chicago

some empirical evidence on stock returns and security credit regulation in the otc equity market abstract this paper studies price reactions of otc stocks that are added to and deleted from the federal reserve board s official list of otc margin stocks we interpret any price reactions as economic effects related to the fed s security credit regulatory activities under the 1969 amendment to the 1934 securities exchange act we test for three effects 1 fed endorsement 2 credit and 3 asymmetric information using both weekly and daily data we find strong positive stock price reactions when otc stocks are added to the fed s list no major effects are discernible when stocks are removed from the fed s list we interpret these findings to be consistent with a credit convenience effect

short selling margin trading and price efficiency evidence from the chinese market abstract china launched a pilot scheme in march 2010 to lift the ban on short selling and margin trading for stocks on a designated list we find that stocks experience negative returns when added to the list after the ban is lifted price efficiency increases while stock return volatility decreases panel data regressions reveal that intensified short selling activities are associated with improved price efficiency short sellers trade to eliminate overpricing by selling stocks with higher contemporaneous returns following a downward trend and their trades predict future returns in contrast we find intensified margin trading activities for stocks with lower contemporaneous returns and these trades have no return predictive power

random competitive exchange price distributions and gains from trade abstract this paper studies the behavior of a competitive exchange under uncertain preferences and random indivisible endowments we obtain explicit closed form results for the price distribution and expected gains from trade both for case where the market is thin and the number of traders is low and for the asymptotic case where the number of traders tends to infinity we demonstrate that increasing the number of traders reduces price variability and increases the expected gains from trade and that increasing the variability of traders reservation prices increases price variability as well as the expected asymptotic gains from trade
