hume s specie flow mechanism and classical monetary theory an alternative interpretation abstract hume s celebrated essay on the international distribution of money has always been criticized for ignoring the law of one price contrary to the traditional interpretation however hume actually maintains that law and argues for the stability of long run equilibrium putting money market equilibrium in the foreground his analysis is essentially founded on the same hypothesis as the modern monetary approach albeit focusing on the supply rather than on the demand side of the money market

s p 500 cash stock price volatilities s p 500 stock return volatilities are compared to the volatilities of a matched set of stocks after controlling for cross sectional differences in firm attributes known to affect volatility no significant difference in volatility is observed between 1975 and 1983before the start of trade in index futures and index options since then s p 500 stocks have been relatively more volatile the difference is statistically but not economically significant the relative increase occurs primarily in daily returns and only to a lesser extent in longer interval returns other factors besides the start of derivative trade could be responsible for the small increase in volatility stock price volatility has received much attention in the popular press over the last few years especially since the october 19 1987 stock market crash the rise in volatility has alarmed investors regulators and the public in general some suggest that the start of trade in stock index futures and index options increased speculative activity that in turn destabilized cash markets causing higher volatility large trading activity in the derivative contracts makes the suggestion plausible volume in index futures and index options increased dramatically since their introductions in 1982 and 1983 by 1987 the average daily dollar volume in the s p 500 futures contracts alone exceeded the dollar volume of cash s p 500 trade by a factor of about two while the dollar value of the daily net change in total open interest is about 8 of s p 500 stock dollar volume speculative trade in futures and options frequently is accused of destabilizing underlying cash markets the charge has been made for more than a century in the agricultural precious metal and currency markets recent evidence by french and roll 1986 showing stock variance to be strongly related to trading session hours heightens these concerns unfortunately theoretical analyses of whether speculative trade destabilizes cash markets lead to conflicting conclusions depending on what assumptions are made 1 school of business administration university of southern california and office of economic analysis u s securities and exchange commission i wish to thank mary denny mcsweeny and steve hornstein for their valuable research assistance and the referee and editor for their many suggestions and insights the opinions expressed in this paper do not necessarily reflect those of the u s securities and exchange commission or those of the author s colleagues on its staff an increase in well informed speculative trade has two opposite effects on measured volatility it decreases volatility due to order flow imbalances caused by uninformed traders because informed traders provide liquidity in such events and it increases volatility due to new fundamental information since the information which is assumed to be generated at discrete time intervals is impounded into

the role of transaction costs for financial volatility evidence from the paris bourse this paper analyzes the causal linkage between transaction costs and financial volatility under two methodological improvements over the existing literature first we use panel data in which exogenous transaction cost differences in the french stock market are induced by price level dependent minimum price variation rules tick size rules unlike in previous studies based on one time regulatory tick size changes like the u s decimalization we can separately identify and control for marketwide volatility changes second we avoid the pitfalls of biased volatility measurement across regimes by using the range as a tick size robust volatility metric panel regressions controlling for marketwide volatility effects show at high levels of statistical significance that the hourly range volatility of individual stocks increases by more than 30 for a 20 exogenous increase in transaction costs due to tick size variations in the french trading system in the light of this evidence higher transaction costs in general and security transaction taxes in particular should be considered as volatility increasing jel f3 g1 g14

the comparative advantage of cities abstract what determines the distributions of skills occupations and industries across cities we develop a theory to jointly address these fundamental questions about the spatial organization of economies our model incorporates a system of cities their internal urban structures and a high dimensional theory of factor driven comparative advantage it predicts that larger cities will be skill abundant and specialize in skill intensive activities according to the monotone likelihood ratio property we test the model using data on 270 us metropolitan areas 3 to 9 educational categories 22 occupations and 19 industries the results provide support for our theory s predictions

trading and pricing in upstairs and downstairs stock markets we provide empirical evidence on the economic benefits of negotiating trades in the upstairs trading room of brokerage firms relative to the downstairs market using helsinki stock exchange data we find that upstairs trades tend to have lower information content and lower price impacts than downstairs trades this is consistent with the hypotheses that the upstairs market is better at pricing uninformed liquidity trades and that upstairs brokers can give better prices to their customers if they know the unexpressed demands of other customers we find that these economic benefits depend on price discovery occurring in the downstairs market copyright 2002 oxford university press

the skill composition of u s cities this article explores why the fraction of highly educated workers varies across u s metropolitan areas it documents a set of facts that pose challenges for a number of theories notably i cities are characterized by industry neutral differences in skilled labor productivity and ii the size of the business services sector is strongly correlated with cities skill compositions motivated by these observations i propose an input sharing model in which nontraded business services complement skilled labor i show that the model accounts for all of the empirical regularities documented in the article

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

internalization and stock price clustering finnish evidence abstract internalization the practice of brokers executing trades in house is a significant phenomenon in the helsinki stock exchange during the continuous trading session 97 5 upstairs market trades are internalized the corresponding figure for after hours upstairs market trades is 73 1 the prices of internalized trades are somewhat more clustered than the prices of other trades during the continuous trading session but they are not more clustered than the prices of negotiated trades in the after hours upstairs market this suggests that finnish brokers do not use a more discrete set of prices for internalized trades than for other upstairs trades

stock price clustering and discreteness stock prices cluster on round fractions clustering increases with price level and volatility and decreases with capitalization and transaction frequency clustering is pervasive price clustering will occur if traders use discrete price sets to simplify their negotiations exchange regulations require that most stocks be traded on eighths clustering on larger fractions will occur if traders choose to use discrete price sets based on quarters halves or whole numbers an econometric model of clustering is derived and estimated projections from the results suggest that traders would frequently use odd sixteenths when trading low price stocks if exchange regulations permitted trading on sixteenths article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

productivity gains from geographic concentration of human capital evidence from the cities abstract based on recent theoretical developments the argument is made that the average level of human capital is a local public good cities with higher average levels of human capital should therefore have higher wages and higher land rents after conditioning on the characteristics of individual workers and dwellings this prediction is supported by data for standard metropolitan statistical areas smsas in the united states where the smsa average levels of formal education and work experience are used as proxies for the average level of human capital the alternative explanations of omitted smsa variables and self selection are evaluated an estimate of the effect of an additional year of average education on total factor productivity is computed

valuation effects of canadian stock split announcements abstract the abnormal returns for two types of announcement dates are examined for a large sample of stock splits on the toronto stock exchange tse the mean abnormal return is positive and statistically significant for the split proposal announcement date and positive and not statistically significant for the split approval date these findings are not only consistent with those found for stock splits in the united states grinblatt masulis and titman 1984 but are also robust to various thin trading autocorrelation and heteroscedasticity adjustments and the exclusion of splitting stocks which are interlisted on non canadian stock markets

tick size share prices and stock splits minimum price variation rules help explain why stock prices vary substantially across countries and other curiosities of share prices companies tend to split their stock so that the institutionally mandated minimum tick size is optimal relative to the stock price a large relative tick size provides an incentive for dealers to make markets and for investors to provide liquidity by placing limit orders despite its placing a high floor on the quoted bid ask spread a simple model suggests that idiosyncratic risk firm size and visibility of the firm affect the optimal relative tick size and thus the share price in stock markets around the world the average price per share differs substantially the median u s stock for example sells for about 40 a typical london stock sells for about 5 7 50 and a typical hong kong share is about 2 furthermore when stock prices rise above a country s usual trading range firms often split their stocks to restore prices to that range why are these price ranges so different among countries these trading ranges can be remarkably stable over time during the half century from 1943 to 1994 the s p composite index increased over 1 500 percent yet the average new york stock exchange nyse share price was

why trading speed matters a tale of queue rationing under price controls we show that queue rationing under price controls is one driver of high frequency trading uniform tick sizes constrain price competition and create rents for liquidity provision particularly for securities with lower prices the time priority rule allocates rents to high frequency traders hfts because of their speed advantage an increase in relative tick size defined as uniform tick sizes divided by security prices increases the fraction of liquidity provided by hfts but harms liquidity we find that the message to trade ratio is a poor cross sectional proxy for hfts liquidity provision stocks with more liquidity provided by hfts have lower message to trade ratios received september 15 2015 editorial decision october 7 2017 by editor robin greenwood

stock splits and stock dividends why who and when this study investigates empirically why firms split their stock or distribute stock dividends and why the market reacts favorably to these distributions the findings suggest that stock splits are mainly aimed at restoring stock prices to a normal range some support can also be found for the oft mentioned signalling motive of stock splits stock dividends are altogether different from stock splits and they appear to be a decreasing phenomenon the clue to stock dividend distributions may lie in their perceived substitution for relatively low cash dividends neither stock splits nor stock dividends are recent phenomena the latter dates back to the elizabethan age among the first to declare such dividends was the east india company which while enjoying great prosperity declared in 1682 a stock dividend of one hundred percent during the eighteenth and nineteenth centuries stock dividends were quite frequently distributed by british companies in the united states an early and frequently discussed stock dividend distribution was that of the new york central railroad just prior to its union with the hudson river railroad in 1869 surprisingly stock dividends were quite popular in the u s despite their being subject to federal income tax thus for example during the seven years prior to 1922 the year in which the supreme court exempted the recipients of stock dividends from taxes the ratio of stock dividends to all dividend distributions was 14 5 percent this ratio increased to a staggering forty seven percent during the seven years succeeding the supreme court decision during 1936 to 1937 some american companies distributed stock dividends to avoid the undistributed profit tax

a theory of urban growth in an economy experiencing endogenous economic growth and exogenous population growth we explore two main themes how urbanization affects efficiency of the growth process and how growth affects patterns of urbanization localized information spillovers promote agglomeration and human capital accumulation fosters endogenous growth individual city sizes grow with local human capital accumulation and knowledge spillovers and city numbers generally increase which we demonstrate is consistent with empirical evidence we analyze whether local governments can successfully internalize local dynamic externalities in addition we explore how growth involves real income differences across city types and how urbanization can foster income inequality most nonagricultural production in developed countries occurs in metropolitan areas the underlying reasons why economic activity agglomerates into cities localized information and knowledge spillover also make cities the engines of economic growth in an we gratefully acknowledge support of the national science foundation grants sbr 9422440 and sbr9730142 for this research the work has benefited from conversations with harl ryder on the dynamics of the model and from comments by gilles duranton and participants in seminars at brown colorado and texas austin and a presentation at an isit seminar sponsored by the centre for economic policy research and the national bureau of economic research

catering through nominal share prices we propose and test a catering theory of nominal stock prices the theory predicts that when investors place higher valuations on low price firms managers respond by supplying shares at lower price levels and vice versa we confirm these predictions in time series and firm level data using several measures of time varying catering incentives more generally the results provide unusually clean evidence that catering influences corporate decisions because the process of targeting nominal share prices is not well explained by alternative theories in frictionless and efficient stock markets there is no optimal nominal pershare stock price a firm s board of directors may choose to split to manage the nominal share price and number of shares outstanding but cannot change its overall market value through these means yet boards typically do manage their firms nominal share price rather than watch it passively drift with returns theories offered to explain share price management include arguments that trading costs depend on nominal prices dolley 1933 angel 1997 that splits signal inside information brennan and copeland 1988 asquith healy and palepu 1989 and ikenberry rankine and stice 1996 or that prices in certain ranges simply constitute a market norm from which there is little gain to deviating rozeff 1998 weld et al 2009 in this paper we propose a catering theory of nominal share prices we define catering as the managerial behavior of increasing the supply of a characteristic that investors appear to be paying a premium for even though that characteristic does not increase fundamental value the catering theory of nominal share prices thus posits that the supply of securities of different price ranges is partly a response to investor demand for securities of different price ranges managers increase the supply of low priced securities

stock splits signaling or liquidity the case of adr solo splits abstract stock splits should have no effect on firm value in perfect capital markets yet stock prices increase on split announcements the two traditional explanations are information signaling and improved liquidity for shares that trade at lower prices we investigate these explanations by studying splits of american depositary receipts adrs that are not associated with splits in their home country stock and which represent unique illustrations of the effect of liquidity we interpret our findings as supportive of the liquidity explanation of stock split announcement effects

marketmaker behavior in an auction market an analysis of scalpers in futures markets this paper focuses on the role of scalpers as marketmakers in the competitive auction of futures exchanges we use transactions data of a representative scalper to identify the source of scalper earnings we find that scalpers provide liquidity services to incoming market orders thereby facilitating commercial hedging scalper earnings are positively related to the bid asked spread and negatively related to the length of time a position is held futures trading is organized as an auction market with buyers and sellers confronting each other directly in a trading pit or ring on an exchange floor bids and offers are represented in the pit by open outcry trades are consummated throughout a trading session which usually last 4 to 6 hours whenever a bid is hit or an offer lifted by some other agent on the floor participants in futures markets include hedgers and speculators whose orders are called in and are represented by floor brokers in the pit in addition floor traders participate by bidding and offering for their own account some floor traders fall into the category of short term speculators day traders who prefer to trade for themselves rather than execute orders through a floor broker a somewhat more specialized group of floor traders are known as scalpers they are essentially marketmakers who quote bids and offers against which market orders can be executed they do not have an affirmative obligation to provide liquidity by quoting bids and offers but do so in the expectation of earning a return this paper examines the activities of scalpers on futures exchanges in order to identify the role of marketmakers in a freely competitive auction we focus on the nature of scalper decision making as well as on the contribution of scalpers to economic welfare one of our main concerns is with the source of a scalper s

a reinterpretation of classical monetary theory relevance to current policy issues is usually not the motivation for studying the history of economic theory however questions about the practicality of conducting monetary policy in a deregulated financial system by controlling the monetary aggregates are stimulating interest in convertibility as an alternative to our present monetary arrangements 3 6 66 since classical writers were mainly concerned with monetary theory and policy under a gold standard it is to be expected that renewed attention will be devoted to classical monetary theory my aim in this paper is to show that contrary to received views about classical monetary theory it was not based on the quantity theory of money on the contrary it was based on a theory of a convertible competitively produced money supply that was fundamentally different from the quantity theory using the modern theory of a competitive money supply we can now rigorously derive many of the basic propositions of classical monetary theory that have been denied or misunderstood by modern theorists operating within the framework of the quantity theory received views about classical monetary theory can be summarized by the following propositions

retrospectives hume on money commerce and the science of economics david hume 1711 1776 is arguably the most esteemed philosopher to have written in the english language during his lifetime however hume was as well if not better known for his contributions to political economy particularly for the essays published as the political discourses 1752 hume left his mark on the economic thought of the physiocrats the classical economists and the american federalists adam smith who met hume circa 1750 was his closest friend and interlocutor for some 25 years among modern economists hume s essays on money and trade have informed theorists of both keynesian and monetarist persuasions in this essay we begin by discussing hume s monetary economics and then spell out his theory of economic development noting his qualified enthusiasm for the modern commercial system we end with an assessment of his views on the scientific standing of economics specifically his counterintuitive argument that economics could be epistemologically superior to physics

cantillon and hume on money and banking the foundations of two theoretical traditions the distinction between the classical monetary theory and quantity theory has been proposed in literature on money and banking the overall feature of the classical theory of money is that it holds one principle of regulation for each kind of issue metallic money bank issues and paper money whereas the quantity theory applied the causality and proportionality postulates for all kinds of monies without claiming to adjudicate the validity of such a distinction the paper investigates the foundation of each tradition in this respect this paper respectively examines and provides a survey of the secondary literature on cantillon s essai and the hume s discourses

ex dividend day stock price behavior discreteness or tax induced clienteles abstract since prices are constrained to discrete tick multiples while dividends are essentially continuous ex day price changes will not equal dividends we argue that the expected price drop is strictly less than the dividend but within one tick of the dividend the price drop to dividend ratio will i be less than one ii increase with dividends generally and iii decline between tick multiples giving a sawtooth pattern in the data since dividends and dividend yields are highly correlated discreteness will give the impression of tax induced dividend clienteles even if there are none taxable cash dividends and nontaxable stock dividends exhibit similar ex day behavior

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

why markets should not necessarily reduce the tick size abstract this paper studies the consequences of a tick size change on the paris bourse thus providing a natural experiment on an order driven market the change raised the tick size for some stocks and lowered it for other in contrast with us exchanges results this generated neither a reduction in liquidity provision for large trades nor a change in the spread based on this paper and on us results it appears an increasing but convex relationship between the relative tick size and the relative spread thus it implies that a new pricing grid does not necessarily lead to change execution costs but it changes the level of transparency in the liquidity supply

tick size bid ask spreads and market structure we propose a link between market structure and the resulting market characteristics tick size bid ask spreads quote clustering and market depth we analyze transactions data of stocks traded on the london stock exchange a dealer market we conclude that market charateristics are endogenous to the market structure the london dealer market does not have a mandated tick size and it exhibits higher spreads higher quote clusterings and higher market depth than the nyse auction market clustering of trade prices is similar in london and new york

making cents of tick sizes the effect of the 2016 u s sec tick size pilot on limit order book liquidity abstract we use the 2016 u s sec tick size pilot to examine the effects of an increase in the minimum price variation on limit order book liquidity in nasdaq listed stocks on the nasdaq exchange for treatment stocks with an average pre pilot quoted spread less than 0 05 the tick size increase is binding and leads to a significant decrease in liquidity in the limit order book specifically the implied cost to trade at and away from the best bid and offer prices increases and the limit order book becomes less resilient the amount of time required for a deviation in liquidity to return to its long run mean for treatment stocks with an average pre pilot quoted spread of at least 0 05 the tick size increase is non binding and leads to either a slight decrease or no change in limit order book liquidity

volatility increases subsequent to nyse and amex stock splits the post split increase in daily returns volatility is less for amex stocks than for nyse stocks the exchange trading location is a significant factor in explaining the volatility shift even after stock price and firm size are considered furthermore when measured on a weekly basis there is no increase in amex stocks returns volatility these results suggest that measurement errors created by bid ask spreads and the 1 8 effect and also one or more of the elements that make the nyse different from the amex explain why the estimated volatility of daily stock returns increases after the ex split date ohlson and penman 1985 provide evidence that nyse stock returns variances increase subsequent to ex stock distribution days for splits of 100 or greater the increase in volatility is independent of the size of the split alnd the post split price seven potential problems that might affect their results are analyzed and rejected 1 ohlson and penman 1985 suggest that the greater post split volatility may be due to the activity of relatively ignorant noisy traders who prefer trading low priced stocks this clientele factor is attributed to black 1986 pg 534 and institutional factors a rather broad category that incorporates measurement problems created by the 1 8 effect and bid ask spreads as possible hypotheses for the post split volatility increase this paper extends ohlson and penman s 1985 analysis to amex stocks exchange listing can serve as a proxy for several real factors that may cause the increase in post split variance many of which are related to the clientele factor and institutional factors cited above if the increase in volatility differs between nyse and amex stocks it will suggest that one or more of the following contributes to the phenomenon

the nominal share price puzzle the average nominal share prices of common stocks traded on the new york stock exchange have remained constant at approximately 35 per share since the great depression as a result of stock splits it is surprising that u s firms actively maintained constant nominal prices for their shares while general prices in the economy went up more than tenfold this is especially puzzling given that commissions paid by investors on trading ten 35 shares are about ten times those paid on a single 350 share we review potential explanations including signaling and optimal trading ranges and find that none of the existing theories are able to explain the observed constant nominal prices we suggest that the evidence is consistent with the idea that customs and norms can explain the nominal price puzzle

a note on the behavior of stock returns around ex dates of stock distributions stock returns after the ex split date is significantly higher than the presplit volatility the increase in the standard deviation of daily returns is of the order of twenty eight to thirty five percent and persists for as long as a full year after the ex date even more interesting is their finding that there is no permanent change in the variance of returns at the announcement date they investigate several potential explanations for this aberration but are unable to find a satisfactory answer grinblatt masulis and titman 6 henceforth gmt examine the behavior of expected returns around announcement dates and exdates for stock distributions exceeding ten percent classifying stock distributions as either stock dividends split factors of twenty five percent or less or stock splits they conclude that return behavior differs across these two types of distributions with stock dividends exhibiting larger abnormal returns than splits this is interpreted by them as evidence in favor of the retained earnings hypothesis the dissimilar accounting treatment of these two types of stock distributions affects retained earnings in different ways and hence splits are not simply large stock dividends this paper extends the work of op to all types of stock distributions in section i postsplit variance is shown to be different from the presplit variance for small stock splits and stock dividends while small splits display an increase in volatility like large splits stock dividends are associated with a decrease in the volatility of returns this evidence also supports gmt s conclusions that stock splits and stock dividends are different types of events section ii investigates the volatility of returns for reverse splits and demonstrates that postsplit volatility decreases for these events this evidence is complementary to woolridge and chambers 9 findings that reverse splits are also associated with negative abnormal returns at their announcement and ex dates section iii concludes the paper

the market reaction to stock splits in this paper a model of market reaction to stock splits is presented and tested we argue that the announcement of a split sets off the following chain of events the market recognizes that subsequent to the reverse split ex day the daily number of transactions along with the raw volume of shares traded will increase decrease this increase in volume results in an increase in the noisiness of the security s return process the increase in noise raises the tax option value of the stock and it is this value that generates the announcement effect of stock splits empirical evidence using security returns daily trading volume and shareholder data strongly supports this theory the evidence in conjunction with this theory also agrees with extant literature that splits result in decreased liquidity but there is no evidence that this reduction in liquidity is priced stock splits have presented finance theorists with a conundrum these nonevents seem to be a purely cosmetic change nevertheless research shows that significant price reaction is attributable directly to splits recently grinblatt masulis and titman 12 show that even in clean cases i e where no other firm specific event coincides with a split announcement stock splits generate a positive abnormal return of close to three percent upon announcement and an additional one percent abnormal return on the ex day the primary contribution of this paper is to provide and empirically support a rational explanation for the split reverse split announcement effect a recent study by ohlson and penman 16 documents a statistical aberration that stock volatilities increase by an average of thirty five percent subsequent to split ex days in this paper we provide a direct statistical extension of ohlson and penman in three directions first we examine reverse splits and demonstrate that they exhibit reductions in volatility second we isolate the shift in volatility as between the nonsystematic and systematic components finally we establish a link between trading volume and the increased volatility copeland 9 shows that contrary to market folklore the liquidity of a stock is actually reduced by a split we provide a statistical extension to copeland by examining the volume pattern of reverse splits copeland observes a drop in split adjusted volume and concludes that liquidity has declined once again we show that the behavior of stocks that reverse split is opposite that of splitting stocks

beta changes around stock splits revisited recent papers by lamoureux and poon 1987 and brennan and copeland 1988 document a significant permanent increase in average beta subsequent to stock split ex dates this paper demonstrates that the shift in estimated beta following ex dates decays as the measurement interval is lengthened there is no statistically significant difference between pre and post split betas using the scholes williams 1977 estimator and weekly return data or using monthly returns we conclude that lamoureux and poon s and brennan and copeland s results can be attributed to a bias created by using too short a return measurement interval to estimate beta

spatial changes in labour market inequality abstract we study spatial changes in labour market inequality for us states and msas using census and american community survey data between 1980 and 2010 we report evidence of significant spatial variations in education employment shares and in the college wage premium for us states and msas and show that the pattern of shifts through time has resulted in increased spatial inequality because relative supply of college versus high school educated workers has risen faster at the spatial level in places with higher initial supply levels we also report a strong persistence and increased inequality of spatial relative demand bigger relative demand increases are observed in more technologically advanced states that have experienced faster increases in r d and computer usage and in states where union decline has been fastest finally we show the increased concentration of more educated workers into particular spatial locations and rising spatial wage inequality are important features of labour market polarization as they have resulted in faster employment growth in high skill occupations but also in a higher demand for low wage workers in low skill occupations overall our spatial analysis complements research findings from labour economics on wage inequality trends and from urban economics on agglomeration effects connected to education and technology

stock dividends stock splits and signaling this paper provides evidence that firms signal their private information about future earnings by their choice of split factor split factors are increasing in earnings forecast errors after controlling for differences in pre split price and firm size furthermore price changes at stock dividend and split announcements are significantly correlated with split factors holding other factors constant and with earnings forecast errors these correlations suggest that management s choice of split factor signals private information about future earnings and that investors revise their beliefs about firm value accordingly the analysis also suggests however that announcement returns are significantly correlated with split factors after controlling for earnings forecast errors this suggests that earnings forecast errors measure management s private information about future earnings with error that split factors signal other valuation relevant attributes or that a signaling explanation is incomplete researchers have long puzzled over the role of stock splits and stock dividends a stock dividend or split increases the number of equity shares outstanding but has no effect on shareholders proportional ownership of shares it is therefore puzzling that firms engage in these transactions and even more so that stock prices rise on average when these transactions are announced as grinblatt masulis and titman 1984 document the significant positive announcement effects led grinblatt masulis and titman hereafter gmt to hypothesize that firms signal information about their future earnings or equity values through their split decisions to date this hypothesis has met with limited support gmt conclude that the announcement returns cannot be explained by forecasts of imminent increases in cash dividends because they observe similar stock price behavior in firms that do not pay dividends our study provides further evidence on the signaling hypothesis by testing whether stock dividends and splits convey information about future earnings and by testing whether the split factor itself is the signal the notion that the split factor may act as a signal has institutional as well as theoretical support practitioners have long contended that the purpose of stock splits is to move a firm s share price into an optimal trading range baker and gallagher 1980 who surveyed chief financial officers of firms that split their shares report that 94 of their sample indicated their stock splits moved their

the effects of stock splits on bid ask spreads this paper examines the effects of stock splits on bid ask spreads for nyse listed companies percentage spreads increase after splits representing a liquidity cost to investors these spread increases are directly related to decreases in share prices following splits and can explain part but not all of the observed increase in return variability after splits the evidence thus suggests a liquidity cost of stock splits that must be weighed against any other perceived benefits of splits such a liquidity cost may validate that stock splits are a signal of favorable information about the firm stock splits have long been a prominent feature in u s financial markets five to ten percent of all amex and nyse firms split in a typical year lakonishok and lev 1987 two potentially conflicting explanations for splits are frequently given first most managers believe baker and gallagher 1980 that splits return share prices to some optimal trading range and improve shareholder liquidity the second explanation is that splits are a costly signal of favorable future prospects for the firm for instance brennan and copeland 1988a show that if stock splits increase liquidity costs to investors such splits can serve as valid signals most empirical studies of the liquidity effects of splits use trading volume copeland 1979 lamoureux and poon 1987 and murray 1985 all conclude that shareholder liquidity decreases after a split based on finding dollar trading volume decreases after splits on the other hand lakonishok and lev 1987 find abnormally high volume in the year preceding a split and abstracting from this abnormal volume that splits are not associated with a change in trading volume the use of volume to measure liquidity is largely motivated by empirical findings of a negative relationship between volume and the bid ask spread e g demsetz 1968 benston and hagerman 1974 and tinic 1972 among others this spread is a direct measure of the cost of liquidity when liquidity is defined hicks 1946 as the ease or rapidity with which a financial instrument can be exchanged for currency despite the importance of the bid ask spread as a liquidity measure only two studies provide evidence on splits and bid ask spreads and they yield conflicting conclusions copeland 1979 studies 162 otc firms for the period 1968 1976 and finds a statistically significant increase in percentage spreads comparing days before and after the ex date murray 1985 studies 100 otc splitting firms for the period 1972 1976 and finds no evidence of a change in percentage spreads relative to a control group

long run substitutability between more and less educated workers evidence from u s states 1950 1990 we estimate the aggregate long run elasticity of substitution between more educated workers and less educated workers the slope of the inverse demand curve for more relative to less educated workers at the u s state level our data come from the five 1950 1990 decennial censuses our empirical approach allows for state and time fixed effects and relies on time and state dependent child labor and compulsory school attendance laws as instruments for endogenous changes in the relative supply of more educated workers we find the aggregate long run elasticity of substitution between more and less educated workers to be around 1 5
