international consumption risk sharing this paper formally examines the implications of international consumption risk sharing for a panel of industrialized countries we theoretically derive the international consumption insurance proposition in a simple setup and show how to modify it in more complicated models we analyze the implications of the theory for pairs of countries and find that aggregate domestic consumption is almost completely insured against idiosyncratic real demographic fiscal and monetary shocks over short cycles but that it covaries with these variables over medium and long cycles the cross equation restrictions imposed by the theory are rejected the policy implications are discussed

characterizing cross country consumption correlations general equilibrium models of international fluctuations that assume complete asset markets predict that consumption will be highly correlated across countries while the data display correlations that are rather low it has become common to characterize this empirical regularity by noting that cross country consumption correlations tend to be lower than corresponding output correlations this note reconsiders that charac terization and demonstrates that it is not particularly robust it also documents a related regularity that is more pervasive consumption fluctuations are more highly correlated with domestic production than with world output this provides an alternative standard for evaluating models of international fluctuations

by force of demand explaining international comovements abstract this paper explores the possibility that economic fluctuations may be largely demand driven it is shown that the stylized open economy business cycle regularities documented by feldstein and horioka 1980 the economic journal 90 june 314 329 and backus et al 1992 journal of political economy 100 4 745 775 can be explained by demand shocks alone even in a standard general equilibrium model frictions such as market incompleteness increasing returns to scale and sticky prices do not appear to be the preconditions for resolving these long standing puzzles

monetary policy and uncertainty in an empirical small open economy model this paper explores optimal policy design in an estimated model of three small open economies australia canada and new zealand within a class of generalized taylor rules we show that to stabilize a weighted objective of output consumer price in ation and nominal interest variation optimal policy does not respond to the nominal exchange this is despite the presence of local currency pricing and due in large part to observed exchange rate disconnect in these economies optimal policies that account for the uncertainty of model estimates as captured by the parameters posterior distrbution similarly exhibit a lack of exchange rate response in contrast to brainard 1967 the presence of parameter uncertainty can lead to more or less aggressive policy responses depending on the model at hand

ex day behavior with dividend preference and limitations to short term arbitrage the case of swedish lottery bonds abstract swedish lottery bonds offer a unique opportunity to study ex day effects in an environment where cash distributions are tax advantaged relative to capital gains thus in the lottery bond market we observe a reversal of the preference for capital gains that researchers have cited as an explanation for the ex day behavior of u s equities further in this market there are barriers to short term arbitrage when prices do reflect the tax preferences of individual investors we find the bonds are priced around the ex day to reflect differential tax rates on income and capital gains consistent with the prevailing tax regimes the bonds consistently experience negative returns over the coupon payment period and in fact often sell at negative yields prior to the cash distribution as one would expect given tax motivated trading between high tax investors who buy prior to the distribution and low tax investors who buy after the distribution

ex day behavior tax or short term trading effects this study examines the behavior of share prices around the ex dividend dates before and after the introduction of the 1988 income and corporation taxes act that reduced substantially the tax differential between dividends and capital gains in the united kingdom we find that in the pre 1988 period when the differential taxation of dividends and capital gains is high ex day returns are positive and significant in contrast in the post 1988 period ex day returns are in most cases negative and insignificant further analysis reveals that while ex day returns are significantly related to dividend yield and to the length of the settlement period they are not affected by the commonly used measures of transaction costs such as the bid ask spread and trading volume or by the day of week month of the year type of dividend distribution or number of days to the actual receipt of the cash dividend we conclude that taxation affects significantly ex day share prices in the previous studies have documented that the risk adjusted abnormal returns on the ex dividend dates are positive and significantly related to the dividend yield the interpretation of these findings is however controversial the question relates to what category of investors sets ex day prices elton and

the ex dividend day behavior of canadian stock prices tax changes and clientele effects with some simple assumptions the ex dividend day price drop and the associated dividend can be used to measure the market s marginal tax rate previous research has estimated the implied tax rate for the u s this paper extends the analysis to canada where the tax treatment of dividends and capital gains is completely different from that in the u s the paper also presents estimates from 1970 80 to include four distinct periods when the tax treatment was different hence we include an implied test of market efficiency as well as those for the relevance of taxes and the existence of tax based dividend clienteles

dividend stripping risk exposure and the effect of the 1984 tax reform act on the ex dividend day behavior this article investigates the importance of risk exposure and the effects of the 1984 tax reform act on the ex dividend day behavior the tax reform appears to have inhibited short term trading activities by increasing the risk exposure of incorporated traders moreover stocks for which existing listed options permitted the reduction of risk through hedged dividend stripping strategies were affected much less from the new tax code than their nonoptionable counterparts this implies that risk affects investors dividend yield choice and that the ex dividend day behavior may be caused in part by the existence of risk premia copyright 1989 by the university of chicago

tastes and technology in a two country model of the business cycle explaining international trade on international financial markets allows people to insure country specific risk and smooth consumption intertemporally equilibrium models of business cycles with trade on global financial markets typically yield international consumption correlations near one and excessive volatility of investment the authors incorporate nontraded goods in the model and find that the implications for aggregate consumption investment and the trade balance are consistent with business cycle properties of industrialized countries however the model driven by technology shocks alone yields counterfactual implications for comovements between consumption and prices at the sectoral level taste shocks produce price quantity relationships more consistent with the data copyright 1995 by american economic association

robust policymaking in the face of sudden stops abstract this paper considers tax policies to deal with sudden stops declines in aggregate activity that are magnified by a binding collateral constraint that occasionally occur in emerging market economies households and or the government are assumed to face model uncertainty and desire robustness against alternative models welfare gains from optimal taxation are small if the government trusts its model of household expectations whether those expectations are altered by model uncertainty or not in contrast welfare losses are large if the government is uncertain about the household s probability model

fiscal deficits and relative prices in a growing world economy abstract this paper studies the transmission of fiscal disturbances between countries and the effect of those disturbances on worldwide capital intensity in a context of growth the model developed to address these issues allows for the production of both nontradable and relatively capital intensive tradable goods a central finding is that factor markets can be a major channel for the communication of fiscal policy shocks to world interest rates to private saving decisions and ultimately to global asset supplies and their distribution among countries particular predictions of the model illustrate how changes in public debt ratios and shifts in government spending patterns affect resource allocation and the welfare of various generations both at home and abroad

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

taxes and dividends the uk evidence abstract this paper provides empirical evidence on the simultaneous effects of both corporation and personal income taxes on dividend payment adjustments and on the behaviour of share prices on the ex dividend dates the results show that companies set their dividend policies to minimise their tax liability and to maximise the after tax return of their shareholders in particular firms that are unable to deduct the advanced corporation tax from their tax liability are found to pay low dividends in addition consistent with the tax hypothesis we find that the differential taxation of dividends and capital gains results in a decrease in ex day share prices by significantly less than the amount of the dividend there is no evidence of a tax induced dividend clientele

a closed form solution for a model of precautionary saving this paper analyses life cycle consumption plans and distinguishes between temporal risk aversion and intertemporal substitution the results assume that felicity functions are quadratic and that income follows a linear model with normally distributed errors stochastic dynamic programming then yields closed loop linear decision rules certainty equivalence no longer holds but instead households play a min max strategy against nature one finds a rationale for precautionary saving and a larger sensitivity of changes in consumption to income innovations

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

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

ex dividend day stock price behavior the case of the 1986 tax reform act this paper analyzes the behavior of stock prices around ex dividend days after the implementation of the 1986 tax reform act that dramatically reduced the difference between the tax treatment of realized long term capital gains and dividend income in 1987 and completely eliminated the differential in 1988 we show that this tax change had no effect on the ex dividend stock price behavior which is consistent with the hypothesis that long term individual investors have no significant effect on ex day stock prices during this time period the results indicate that the activity of short term traders and corporate traders dominates the price determination on the ex day

new evidence that taxes affect the valuation of dividends this paper uses british data to examine the effects of dividend taxes on investors relative valuation of dividends and capital gains british data offer great potential to illuminate the dividends and taxes question since there have been two radical changes and several minor reforms in british dividend tax policy during the last 30 years studying the relationship between dividends and stock price movements during different tax regimes offers an ideal controlled experiment for assessing the effects of taxes on investors valuation of dividends using daily data on a small sample of firms and monthly data on a much broader sample we find clear evidence that taxes affect the equilibrium relationship between dividend yields and market returns these findings suggest that taxes are important determinants of security market equilibrium and deepen the puzzle of why firms pay dividends financial economists have long been puzzled by corporate dividend behavior many individual investors should value a dollar of corporate dividends less than a dollar of corporate retentions because the former gives rise to greater tax liabilities corporations however face equal costs of paying out dividends and retaining earnings miller and modigliani 31 demonstrated that in the absence of taxes dividend policy should have no effect on share valuation if dividends are tax penalized however a value maximizing firm should pay no dividends widespread dividend payments to taxable investors are therefore surprising in 1981 dividend tax revenues in the united states were estimated to exceed 20 billion dollars indeed some have interpreted the large volume of dividends paid as evidence against the rational behavior postulates typically used by economists the dividend question has stimulated a large theoretical and empirical literature concerned with the qluestion of investors valuation of dividends in particular the question of how taxes affect the market valuation of dividends has generated considerable controversy numerous studies including auerbach 2 litzenberger and ramaswamy 24 26 morgan 34 and rosenberg and marathe

equity markets and personal taxation the ex dividend day behaviour of finnish stock prices abstract this paper analyzes the ex dividend day behaviour of stock prices in the finnish stock market the tax structure in finland is strikingly similar to the new tax structure in the u s which was for the first time in effect during the fiscal year 1987 the results in this paper may thus also illuminate the ex dividend day behaviour in the u s stock markets under the new tax law our empirical data show that the average drop in the stock prices on their ex dividend days has been 90 of the amount of the dividend during the years of 1974 to 1985 this is shown to be consistent with the tax explanation taking into account the finnish tax laws it is especially shown that the marginal seller on the ex dividend days is an individual investor with a marginal tax rate of approximately 50

elastic attention risk sharing and international comovements in this paper we examine the effects of elastic information processing capacity or elastic attention proposed in sims 2010 on international consumption and income correlations in a tractable small open economy soe model with exogenous income processes we find that in the presence of capital mobility in financial markets elastic attention due to a fixed information processing cost lowers the international consumption correlations by generating heterogeneous consumption adjustments to income shocks across countries facing different macroeconomic uncertainty in addition we show that elastic attention can improve the model s predictions for the other key moments of the joint dynamics of consumption and income

the real exchange rate the capital stock and fiscal policy abstract this paper studies the joint determination of aggregate supply the real exchange rate and the current account in response to changes in government spending in a model where there is no uncertainty in the aggregate but where individuals are uncertain about their lives duration international capital mobility fixes the steady state capital stock and aggregate supply in a small country whereas in a large country the steady state capital stock is endogenous an increase in government spending is more likely to generate a real exchange rate depreciation in a small country since the loss of wealth associated with cumulated current account deficits does not increase rest of the world spending in the case of a large country current account deficits are wealth transfers to the rest of the world and increase foreign spending thus the normal long run response is an increase in the relative price of domestic output

robustness information processing constraints and the current account in small open economies article i nfo in this paper we examine the effects of two types of induced uncertainty model uncertainty due to robust ness rb and state uncertainty due to finite information processing capacity called rational inattention or ri on consumption and the current account we show that the combination of rb and ri improves the model s predictions for i the contemporaneous correlation between the current account and income and ii the volatility and persistence of the current account in small open emerging and developed economies in addition we show that the two informational frictions improve the model s ability to match the impulse response of consumption to income and the relative volatility of consumption to income growth

portfolio rebalancing and the effective taxation of dividends and capital gains following the tax reform act of 1986 abstract the tax reform act tra of 1986 among other things equalized the nominal taxation of dividend and capital gains income the evidence is consistent with the hypothesis that ordinary investors rebalanced their portfolio holdings in response to the new taxes such rebalancing appears to have concentrated on liquid stocks indicating that transaction costs are an important consideration for ordinary investors involved in restructuring their portfolio holdings the tax clientele relationships that existed prior to the new act were distorted temporarily but have reappeared by 1988 interestingly investors post reform effective tax rates still give a preference to capital gains as they did prior to the tax reform

dividends and taxes evidence on tax reduction strategies this article investigates two aspects of dividend tax avoidance not addressed by prior research first it examines the aggregate dividend tax savings provided to individuals through tax exempt and tax deferred accumulators using the internal revenue service individual income tax model it then proceeds to determine whether specific provisions of the internal revenue code such as the preferential treatment of capital gains the investment interest limitation and the 100 dividend exclusion affect the individual s choice of investment income finally it provides a direct estimate of the average marginal tax rate on dividends that takes into account tax favored accumulators copyright 1990 by the university of chicago

robust monetary policy in a small open economy abstract we study how a central bank in a small open economy should conduct monetary policy if it fears that its model is misspecified using a new keynesian model of a small open economy we solve analytically for the optimal robust policy rule and the equilibrium dynamics and we separately analyze the consequences of central bank robustness against misspecification concerning the determination of inflation output and the exchange rate we show that an increase in the preference for robustness makes the central bank respond more aggressively or more cautiously to shocks depending on the type of shock and the source of misspecification

the ex dividend day behavior of stock prices a re examination of the clientele effect a comment in a recent article in this journal kalay 5 has written an extensive comment on our 1970 article 2 concerning marginal stockholder tax rates and the clientele effect while we are flattered that our article is viewed of sufficient importance to gain this attention 12 years after it was written we do have reservations about kalay s comments we are principally concerned with his interpretations of relevant transaction costs and the role they play in setting equilibrium

the ex dividend day behavior of stock prices the case of japan we provide a comprehensive empirical analysis of stock price behavior around the ex dividend day in japan we find that prices rise on the ex day and that dividend related tax effects appear to be secondary returns around ex dividend days are dominated by the proximity of many ex days to the fiscal year end excess returns of 1 percent which are independent of any dividend related considerations are higher than round trip transaction costs on medium sized transactions prices seem to imply selling pressure before and buying pressure at the start of the new fiscal year these trading patterns appear to be motivated by intercorporate manipulative trading around the end of the firms fiscal year which are unrelated to dividends article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

stock markets adjustment costs and the international transmission of shocks this paper studies the role of stock markets and adjustment costs in the international transmission of supply shocks it uses an analytically tractable two country one good model where intertemporal optimizing behaviour of infinitely lived agents endogenously determines the rate of capital accumulation and the current account it is shown that the presence of adjustment costs and stock markets provide new insights concerning the channels through which supply shocks are internationally transmitted

international business cycles with endogenous incomplete markets backus kehoe and kydland 1992 baxter and crucini 1995 and stockman and tesar 1995 find two major discrepancies between standard international business cycle models with complete markets and the data in the models cross country correlations are much higher for consumption than for output while in the data the opposite is true and cross country correlations of employment and investment are negative while in the data they are positive this paper introduces a friction into a standard model that helps resolve these anomalies the friction is that international loans are imperfectly enforceable any country can renege on its debts and suffer the consequences for future borrowing to solve for equilibrium in this economy with endogenous incomplete markets the methods of marcet and marimon 1999 are extended incorporating the friction helps resolve the anomalies more than does exogenously restricting the assets that can be traded

ex dividend returns the mexican puzzle abstract we study ex dividend returns in mexico where an imputation system entitles individual investors to a net dividend tax credit based on taxation we expect ex day abnormal returns to be negative or at most zero in mexico however they are significantly positive because ex day returns are positive even for stocks restricted to mexican nationals they are not attributable to foreign stockholders tax considerations none of the market microstructure based hypothesis in the literature can explain these positive ex day returns ex day returns in mexico are a puzzle

explaining saving investment correlations national saving and investment rates are highly positively correlated in virtually all countries this is puzzling as it apparently implies a low degree of international capital mobility this paper shows that the observed positive correlation between national saving and investment rates arises naturally within a quantitatively restricted equilibrium model with perfect mobility of financial and physical capital the model is consistent with the fact that saving investment correlations are larger for larger countries but are still substantial for small countries further the model is consistent with the finding that current account deficits tend to be associated with investment booms copyright 1993 by american economic association

market valuation of tax timing options evidence from capital gains distributions we examine a distribution that is taxed as a capital gain rather than as a dividend since the distribution induces a realized capital gain while the price change is an unrealized gain ex day return behavior provides evidence of the value of tax timing capital gains we show that investors are compensated 7c in unrealized gains for each dollar of realized capital gains that is 1 of realized capital gains is equivalent to 93c of unrealized gains an investor with a tax rate on realized gains of 15 has an effective tax rate on unrealized capital gains of 8 6 capital gains taxes can be deferred until assets are sold this feature provides the investor who purchases a security with an option regarding the timing of the realization of capital gains and losses this option can be used to lower one s expected tax liability even if capital gains tax rates remain constant for different holding periods an investor who delays the realization of a gain effectively enjoys compound returns on the postponed taxes if capital losses are tax deductible or partially tax deductible tax timing is even more valuable since investors can follow the strategy of selling stocks with capital losses early while postponing the sale of winners recent evidence lends support to the contention that some investors respond to this tax timing option for example odean 1998 shows that u s investors are more likely to sell losers in december than other months similarly grinblatt and keloharju 2002 show that at the end of the tax year finnish investors are more likely to realize losses than gains this type of tax motivated trade seems to affect market returns as shown by poterba and weisbenner 2001 who demonstrate that end of year tax loss selling is related to return variation in the month of january

signal extraction and rational inattention i introduction the objective of this paper is to compare two theories of information frictions in the first theory agents observe the state of the world with exogenously imposed noise we refer to this environment as the signal extraction se model 1 the second theory permits agents to design the distribution of noise terms by focusing limited attention on certain variables at the expense of others following sims 2003 we refer to this model as the rational inattention ri model 2 in both models agents respond to changes in the true underlying state slowly because it takes time for them to learn exactly what the new state is the key difference is that the noise distribution under ri is an outcome of optimal choice and thus can adapt to changing circumstances in the economy whereas under se the noise distribution is technologically fixed our goal is to explore this crucial distinction we explore the distinction between se and ri within a linear quadratic gaussian lqg setting we first study a univariate case for which the variance covariance matrix of the noise shocks can be solved in closed form first we note that at least within the lqg framework any variance covariance structure for the noise shocks derived from the ri problem can be exogenously imposed in the se environment so there is a sense in which the two environments are observationally equivalent the next result we find is that if the variance of the noise itself is fixed we can use a policy experiment to distinguish se from ri suppose that the variance of an exogenous shock is scaled up because of a change in policy in the se problem where the distribution of noise is exogenous an increase in the variance of the shock will lead to a different solution for the conditional variance and kalman gain consequently the change in policy will lead to a change in the model s dynamic behavior and the agent s payoffs in contrast in the ri problem if channel capacity is fixed a change in the variance of the exogenous shock will lead to the same change in the conditional variance of the state and the variance of the noise but will not affect the kalman gain that is inattentive agents with fixed capacity will behave as if they face noise shocks whose nature changes systematically as the dynamic properties of the economy change with policy furthermore we show that if we assume that the marginal cost of information is fixed capacity will be elastic with respect to a change in policy consequently the kalman gain in this case will also adjust in response to the policy change the losses of agents due to imperfect information depend on the value of the kalman gain therefore in general se and ri imply different policy recommendations in contrast we also find that in the univariate case if the ratio of the variance of the exogenous shock to that of the noise i e the signal to noise ratio snr is fixed the se and ri problems are observationally equivalent in the sense that they lead to the same dynamics of the model economy when the ratio of the conditional variance to that of the noise in the se problem equals a particular function of the channel capacity in the ri problem our results do not depend on the presence or absence of correlation between fundamental and noise shocks specifically in the presence of the correlation a change in the variance of the exogenous shock does not change the dynamic behavior of the model in the fixed capacity case whereas it changes the model s dynamics in the fixed information processing cost case in which both the variance of noise and the kalman gain are affected by the interactions between the correlation the variance of the fundamental shock and the conditional variance we then move on to study the multivariate case in this case given channel capacity the conditional variance covariance matrix can be obtained by solving a semidefinite programming problem in which the inattentive agent minimizes the expected loss due to information processing constraints

temporary and permanent government spending in a small open economy abstract this paper studies a dynamic optimizing small open economy model that emphasizes the supply side responses of labor and capital to changes in fiscal policy the model used generates results that are consistent with a number of empirical regularities in small open economies furthermore temporary fiscal shocks are shown to have permanent positive effects on output and negative effects on consumption and welfare the strength of these effects are shown to depend on intertemporal elasticities of substitution and the persistence of policies

foreign and domestic investors and tax induced ex dividend day trading abstract this paper reports evidence on the consequences of differential tax treatment for domestic and foreign owners in a market with a high degree of foreign ownership for certain stocks the helsinki stock exchange hse we find that ex dividend day ratios vary with the degree of foreign ownership and detect significantly abnormal ex dividend day trading volumes the average ex dividend price drops for high yield high foreign ownership stocks are likely to lie outside no arbitrage boundaries for domestic taxable investors an investigation of short selling through a derivatives instrument also reveals significant excess trading volumes in ex dividend months the tax heterogeneity of the company s ownership structure seems to play a role in explaining deviations from dividend neutrality more deviations are observed for companies with a more homogeneous ownership structure in terms of taxation

why do stock prices drop by less than the value of the dividend evidence from a country without taxes abstract it is well documented that stock prices on ex dividend days drop by less than the value of the dividend on average this has commonly been attributed to the effect of tax clienteles we examine data from the hong kong stock market where neither dividends nor capital gains are taxed as in the u s the average stock price drop is less than the value of the dividend specifically the average dividend for the period 1980 1993 is hk 0 12 and the average price drop is hk 0 06 we are able to account for this both theoretically and empirically through market microstructure arguments

new evidence on the impact of tax loss selling on the turn of the year effect abstract the turn of the year effect is an empirical regularity which refers to the observation that equity returns on days around the turn of the calendar year are significantly high a common explanation for the effect is the tax loss selling hypothesis three studies have tested this hypothesis by examining equity returns before and after the introduction of the war revenue act of 1917 however these studies have reached inconsistent conclusions following these inconsistent findings this paper examines whether the previous findings are robust to the extension of the pre tax period or whether the previous findings are robust to the use of daily data in contrast to the evidence from existing research which has used daily data a significant turn of the year effect is found prior to 1917 furthermore this effect is shown to be independent of other empirical regularities such as the turn of the month effect and the holiday effect and seasonality in dividend payments cannot explain the finding thus we conclude that the tax loss selling hypothesis cannot offer a complete explanation of the turn of the year effect

international robust disagreement the literature on disagreement documents that exogenous heterogenous beliefs can explain several key features of both domestic and international asset prices among others anderson ghysels and juergens 2005 and beber breedon and buraschi 2010 we show that concerns about model misspecification paired with consumption home bias can generate persistent endogenous disagreement across countries even when i they share the same approximating model ii endowments are i i d and markets are complete and frictionless when agents fear model misspecification hansen and sargent 2007 they slant probabilities toward worst case outcomes and base their economic choices on their distorted subjective probabilities in our two country two good economy consumption home bias generates endogenous disagreement in about the worst case scenario since each country fears a low supply of its most preferred good disagreement on the worst case scenario generates different distorted expectations about the growth rates of the local endowments even in the case in which all goods share the same objective probability distribution according to recent findings in the literature on risk sharing with heterogenous consumers and recursive preferences anderson 2005 colacito and croce 2011 borovicka 2011 our economy features permanent disagreement with a well defined ergodic distribution of beliefs

optimal monetary policy with imperfect common knowledge we study optimal nominal demand policy in a flexible price economy with monopolistic competition where firms have imperfect common knowledge about the shocks hitting the economy information imperfections emerge endogenously because firms are assumed to have finite shannon capacity to process information we then ask how policy that minimizes a quadratic objective in output and prices depends on firms processing capacity when price setting decisions of firms are strategic complements we find that policy should nominally accommodate white noise mark up shocks for a large range of capacity values this fi nding is robust to the policy maker observing shocks imperfectly or being uncertain about firms processing capacity when mark up shocks are persistent accommodation may even have to increase in the medium term but has to decrease in the long run thereby generating a hump shaped price response and a slow reduction in output instead when prices are strategic substitutes policy tends to react with nominal demand contractions to mark up shocks in addition there might exist discontinuities between common knowledge equilibria and equilibria with small amounts of imperfect common knowledge

marginal stockholder tax effects and ex dividend day price behavior evidence from taxable versus nontaxable closed end funds almost all research on the movement of stock prices on ex dividend days has found that prices decline by less than the dividend though this is consistent with tax effects several papers have argued that this phenomenon could be caused by market microstructure effects in this paper we make use of a natural experiment that provides support for the tax explanations of ex dividend behavior some closed end funds have taxable and some have nontaxable dividend distributions both types are subject to taxes on capital gains the implication of this for ex dividendday price behavior is very different between these two types of funds if taxes matter this paper demonstrates that the direction of ex dividendday price behavior is consistent with a tax explanation and that ex dividend day price behavior changes as theory would suggest with changes in the tax law

what can explain the apparent lack of international consumption risk sharing recent research in international business cycles finds that international consumption comovements do not match the risk sharing predictions of standard complete markets models in this paper i ask whether two different types of explanations can help explain this result 1 nonseparabilities between tradables and nontradable leisure or goods and 2 the effects of capital market restrictions on consumption risk sharing i find that risk sharing cannot be resolved by either explanation alone however when i allow for both nonseparabilities and certain market restrictions risk sharing among unrestricted countries cannot be rejected this evidence suggests that a combination of these two effects may be necessary to explain consumption risk sharing across countries

ex date stock price adjustment to stock dividends a note many recipients of stock dividends look upon them as distributions of corporate earnings and usually in an amount equivalent to the fair value of the additional shares received furthermore it is to be presumed that such views of recipients are materially strengthened in those instances which are by far the most numerous where the issuances are so small in comparison with the shares previously outstanding that they do not have any apparent effect upon the share market price and consequently the market value of the shares previously held remains substantially unchanged

tax induced trading of equity securities evidence from the adr market we examine ex dividend date trading of american depositary receipts adrs using a sample of 1 043 dividends over the period 1988 to 1995 adr dividends are often subject to foreign withholding taxes creating incentives for certain investors to avoid the distribution adrs exhibit negative abnormal ex dividend day returns and their prices behave consistently with their related withholding taxes abnormal trading volume for taxable issues exceeds 130 percent and 300 percent of normal volume on the cum and ex dates respectively abnormal volume is an increasing function of foreign withholding tax rates and decreasing function of transactions costs this abnormal exdate trading activity is consistent with tax motivated trading this paper provides empirical evidence from a sample of american depositary receipts adrs that foreign taxes on dividend income are positively associated with abnormal ex dividend day trading activity researchers have long been interested in the question of whether taxes affect investor behavior around ex dividend days such work has implications for corporate financial and distribution policies and for government tax policies adrs provide a unique setting in which to examine the effects of taxes on investor trading behavior because of the unique features of the foreign withholding taxes that apply to them a number of studies have attempted to isolate the determinants of ex dividend day pricing and trading activity of u s equities and there is considerable evidence of tax induced investor behavior around the ex dividend day for common

realistic cross country consumption correlations in a two country equilibrium business cycle model abstract a well known feature of one good multi agent arrow debreu economies with edentical additively separable homothetic preferences is that the consumptions of all agents are perfectly correlated such economies are widely used in interpreting business cycles but seem to be inconsistent with observed cross country correlations of aggregate consumption this paper provides an example of a two country real business cycle model in which preferences are not separable between consumption and labor supply the model has a simple closed form solution closed form solution and allows for fluctuations in labor supply in equilibrium moreover it generates correlations between national consumption rates which are close to some of those observed in historical data jel f41

capital accumulation and the current account in a two country model abstract this paper examines the joint determination of international debt and capital accumulation in a two country model national rates of time preference are endogenous adjusting along an optimal path to come into equality with one another in the steady state the characteristics of short run current account dynamics are crucially linked to world capital accumulation and to a country s long run net external asset position steady state creditor countries tend to have current account surpluses during episodes of world output growth and vice versa for debtor countries this gives rise to possible non monotonic adjustment in the current account and consumption

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

dividends taxes and common stock prices the ex dividend day behavior of common stock prices before the income tax this study examines the ex dividend day behavior of common stock prices before the enactment of the federal income tax on ex dividend days during the pre tax period stock prices fell on average by the full amount of the dividend the data are consistent with the hypothesis that i investors in the pre tax period value dividends and capital gains as perfect substitutes and ii the differential taxation of dividends and capital gains has since caused investors to discount the value of taxable cash dividends in relation to capital gains

tax induced trading around ex dividend days abstract this paper investigates trading volume around ex dividend days for taxable distributions cash dividends it is found that trading volume increases significantly around the ex dividend day this increase is more pronounced for high yield actively traded stocks and after brokerage commissions became negotiable the results are consistent with the hypothesis that short term traders have an impact on ex day price behavior at least for taxable distributions for non taxable distributions stock splits and stock dividends we find negative abnormal volume around ex day

tax reform and ex dividend day behavior this paper investigates the effect of a major canadian tax reform on the ex dividend day behavior of companies on the toronto stock exchange the results are inconsistent with the hypothesis that price changes on ex dividend days reflect the relative taxation of dividends and capital gains for the representative investor but are consistent with the hypothesis that ex dividend day price behavior reflects short term trading activities

the effect of tax heterogeneity on prices and volume around the ex dividend day evidence from the milan stock exchange to investigate the effect of taxation on stock price and trading volume around the ex dividend day we use the italian stock market where dividends on two classes of stock are taxed differently we find that the weighted average of investors tax rates is reflected in the ex day prices and the variance of the relative tax rate across investors is reflected in the volume of trades we also show that higher transaction costs result in higher ex dividend day excess returns and lower abnormal volume this finding is consistent with profit elimination activity by institutions and corporations article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

tick size nyse rule 118 and ex dividend day stock price behavior abstract bali and hite 1998 and dubofsky 1992 propose models in which market microstructure effects play a role in the ex dividend day price drop anomaly bali and hite suggest that the anomaly is caused solely by price discreteness while dubofsky suggests that nyse rule 118 is also involved we test these models by examining cum to ex day price drops during the one eighth one sixteenth and decimal tick size regimes while the evidence is qualitatively consistent with dubofsky s predictions neither model is satisfactory in a quantitative sense one of our main empirical findings is that no significant decline was evident in the magnitude of the ex day anomaly after the tick size reduction

adjustment costs in investment time preferences and the current account abstract this paper studies the effects of supply and demand shocks on the optimal investment and savings decisions of economic agents in a small open economy the two building blocks of the setup are adjustment costs in investment and a recursive time preference structure it is shown that the model can mimic certain stylized facts

dividend taxation in firm valuation new evidence in this paper we develop a residual income model showing how taxes on dividends affect the relative valuation of retained earnings versus contributed equity as well as the value of expected future earnings tests of predictions from our model for a sample of compustat firms from 197594 suggest that overall firm value and the relative valuation weights investors assign to retained earnings contributed equity and current earnings all critically depend on dividend taxes the findings also suggest that investors take a proprietary perspective in valuation and impute an unrecorded shareholder level tax liability on retained earnings the u s tax system subjects retained earnings to dividend taxes upon distribution to shareholders while contributed equity is returned to shareholders as a nontaxable return of capital from the shareholder s proprietary perspective therefore retained earnings should be valued on

ex dividend price behavior of common stocks this study examines common stock prices around ex dividend dates such price data usually contain a mixture of observations some with and some without arbitrageurs and or dividend capturers active our theory predicts that such mixing will result in a nonlinear relation between percentage price drop and dividend yield not the commonly assumed linear relation this prediction and another important prediction of theory are supported empirically in a variety of tests marginal price drop is not significantly different from the dividend amount thus over the last several decades one for one marginal price drop has been an excellent average rule of thumb article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

a theory of demand shocks this paper presents a model of business cycles driven by shocks to consumer expectations regarding aggregate productivity agents are hit by heterogeneous productivity shocks they observe their own productivity and a noisy public signal regarding aggregate productivity the public signal gives rise to noise shocks which have the features of aggregate demand shocks they increase output employment and inflation in the short run and have no effects in the long run numerical examples suggest that the model can generate sizable equilibrium dsge models of the business cycle include a large number of shocks to technol ogy monetary policy preferences etc but typically do not include expectational shocks as independent drivers of short run fluctuations 1 this paper explores the idea of expectation driven cycles looking at a model where technology determines equilibrium output in the long run and consumers receive noisy signals about technology in the short run the presence of noisy signals produces expectational errors this paper studies the role of these expectational errors in gener ating volatility at business cycle frequencies the model is based on two ingredients first consumers take time to recognize permanent changes in aggregate fundamentals although they may have good information on the current state of the individual firm or sector where they operate they have only limited information regarding the long run determinants of aggregate activity second consumers have access to public information that is relevant to estimate long run productivity this includes news about technological innovations publicly released macroeconomic and sectoral statistics financial market prices and public statements by policy makers however these signals provide only a noisy forecast of the long run effects of technological innovations this opens the door to noise shocks which induce consumers to temporarily overestimate or underestimate the productive capacity of the economy

an examination of ex dividend day stock price movements the case of nontaxable master limited partnership distributions this study examines the unit stock price and volume behavior of master limited partnerships mlp around the ex dividend day since the dividends of mlps are not taxable to the unitholder tax based hypotheses predict no abnormal unit movements around the ex day significant positive excess returns and volume are found before the ex dividend day and significant negative excess returns are found on the ex dividend day the findings which are not significantly impacted by the tax reform act of 1986 suggest ex day stock movements are not solely a function of investor marginal tax rates or corporate trading behavior elton and gruber s 1970 findings that in 1966 67 stock prices fell on average by less than the amount of the dividend on the ex dividend date and that the ratio of the price decrease to the dividend was correlated with the dividend yield have led to the development of a tax clientele hypothesis relating to investor behavior one puzzling result from their study was the finding that the price decreases for the highest yielding securities were significantly greater than the dividends which in their analysis implied an investor clientele with negative tax rates while michaely 1989 using 1986 87 data was unable to find support for the tax clientele hypothesis across different yield groups he also documented the large price drop for the highest yielding securities michaely 1989 suggested that his results may demonstrate a preference of corporations for dividend over capital gains because of favorable tax treatment corporations receive on dividend income corporate trader hypothesis shefrin and statman 1984 however suggest that preferences for dividends over capital gains may exist for nontax reasons such as self control or a desire to segregate gains and losses the purpose of this paper is to examine the ex dividend day stock price behavior of master limited partnership mlp units during the 1985 88 period dividends from these high yielding securities are not taxable therefore support for either the tax clientele hypothesis or the corporate trader hypothesis would be found only if the average ex day price change on mlps equalled the dividend this result would also be consistent with barclay s 1987 finding that before the enactment of an income tax in 1913 even high

a microstructure analysis of ex dividend stock price behavior before and after the 1984 and 1986 tax reform acts this article extends ex dividend research by explicitly modeling trading at bid and ask quotations this refinement distinguishes between buying and selling for long term investors and short term dividend capture traders it also explicitly incorporates the bid ask spread and eliminates some potential measurement errors that may bias returns marginal conditions are tested during 1983 and 1988 periods that span the 1984 and 1986 tax reform acts results for long term investors are consistent with the elimination of favorable capital gains tax rates at observed prices tax neutral short term traders cannot profit corporate dividend capture traders face profit opportunities during 1983 that disappear by 1988 copyright 1996 by university of chicago press

model uncertainty and intertemporal tax smoothing in this paper we examine how model uncertainty due to the preference for robustness rb aects optimal taxation and the evolution of debt in the barro tax smoothing model 1979 we rst study how the government spending shocks are absorbed in the short run by varying taxes or through debt under rb furthermore we show that introducing rb improves the model s predictions by generating i the observed relative volatility of the changes in tax rates to government spending ii the observed comovement between government decits and spending and iii more consistent behavior of government budget decits in the us economy finally we show that rb can also improve the model s predictions in the presence of multiple shocks

precautionary saving and persistent current account imbalance abstract the neoclassical representative agent model attributes persistent current account imbalance to differences in time preference rates exogenous time preference yields corner solutions in which one country owns the world s wealth with endogenous time preference corners are avoided but at the cost of the intuitively unappealing assumption that wealthier agents are more impatient this paper shows that an agent with constant relative risk aversion utility subject to stochastic income shocks has a risk adjusted rate of time preference which is increasing in wealth precautionary saving falls as wealth rises allowing avoidance of corner solutions with an intuitively appealing assumption about behavior

current accounts in debtor and creditor countries the authors reexamine a classic question in international economics what is the current account response to a transitory income shock such as a temporary improvement in the terms of trade a transfer from abroad or unusually high production to answer this question they construct a world equilibrium model in which productivity varies across countries and international borrowing and lending take place to exploit good investment opportunities despite its conventional ingredients the model generates the novel prediction that favorable income shocks lead to current account deficits in debtor countries and current account surpluses in creditor countries evidence from thirteen oecd countries broadly supports this theoretical prediction

optimal sticky prices under rational inattention this paper presents a model in which price setting firms decide what to pay attention to subject to a constraint on information flow when idiosyncratic conditions are more variable or more important than aggregate conditions firms pay more attention to idiosyncratic conditions than to aggregate conditions when we calibrate the model to match the large average absolute size of price changes observed in micro data prices react fast and by large amounts to idiosyncratic shocks but only slowly and by small amounts to nominal shocks nominal shocks have strong and persistent real effects we use the model to investigate how the optimal allocation of attention and the dynamics of prices depend on the firms environment jel e 3 e5 d8

personal income taxes and the january effect small firm stock returns before the war revenue act of 1917 a note this paper tests the tax explanation of the january effect by examining small firm stock returns before the war revenue act of 1917 no evidence of a turn of the year effect is found this paper also extends previous authors work on the subject to 191829 a january effect is found during that period the large abnormal returns earned by small firm stocks during the first few days of january is attracting considerable attention from financial economists specifically keim 10 shows that over the entire 1963 79 period the average difference between risk adjusted returns of small and large firms is about 0 7 per day during january even more striking is the finding of keim 9 that over the entire 1931 78 period the relation between daily abnormal returns and size is always negative and more pronounced in january than in any other month similarly ibbotson and sinquefield 8 note that the average return on the quintile of nyse stocks with the lowest market values exceeds the return on the standard and poor s corporate index for 50 of the 56 januarys from 1926 81 there is no accepted theory linking the excess returns of small firms in january with the change of the tax year nevertheless the plausibility of a relation between taxes and stock return seasonality has led roll 17 brown et al 6 berges mcconnell and schlarbaum 2 and reinganum 16 among others to investigate personal income taxes as an explanation for the january effect this paper uses a different methodology and reaches stronger conclusions than any of the above papers specifically i examine the returns of small firms for the period from 1900 to 1929 prior to the revenue act of 1917 marginal income tax rates for investors were very low or zero the major finding of this paper is that there is no evidence that small firms earned abnormal returns in january prior to the 1917 tax act i also show that a january effect does appear during the years 1918 29 therefore i cannot reject a tax explanation for the january effect

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

robust control informational frictions and international consumption correlations abstract in this paper we examine the effects of model misspecification robustness or rb on international consumption correlations in an otherwise standard small open economy model with endogenous capital accumulation we show that in the presence of capital mobility in financial markets rb lowers the international consumption correlations by generating heterogeneous responses of consumption to productivity shocks across countries facing different macroeconomic uncertainty in addition we show that rb can also improve the model s predictions in three other moments of consumption dynamics the relative volatility of consumption to income the persistence of consumption and the correlation between consumption and output after calibrating the rb parameter using the detection error probabilities we show that the model can explain the observed international consumption correlations as well as the other consumption moments quantitatively finally we show that the main conclusions of our benchmark model do not change in an extension in which the agent cannot observe the state perfectly due to finite information processing capacity
