interpreting comovements in the trade balance and the terms of trade abstract i examine the relation between the trade balance and the terms of trade in a two country dynamic stochastic exchange economy with complete markets along an equilibrium path for this economy the relation is governed by the substitutability between foreign and domestic goods i find in contrast to non stochastic analyses of the harberger laursen metzler effect that a positive association does not require persistent shocks or non constant rates of time preference this contrast highlights the role played by the structure of asset markets complete and otherwise in generating equilibrium comovements

the relative yields on taxable and tax exempt debt a valuation model for corporate tax liabilities is developed and used to derive a relationship for the relative yields of taxable and tax exempt debt the model incorporates both the incomplete tax loss offset of the u s corporate tax code and the resulting probabilistic marginal tax rate the relationship is then tested using regression analysis the results are both positive and strong copyright 1986 by ohio state university press

taxes on tax exempt bonds implicit tax rates priced in the cross section of municipal bonds are approximately two to three times as high as statutory income tax rates with implicit tax rates close to 100 using retail trades and above 70 for interdealer trades these implied tax rates can be identified because a portion of secondary market municipal bond trades involves income taxes after valuing the tax payments market discount bonds which carry income tax liabilities trade at yields around 25 basis points higher than com parable municipal bonds not subject to any taxes the high sensitivities of municipal bond prices to tax rates can be traced to individual retail traders dominating dealers and other institutions the issue of how taxes affect asset prices is an important issue in finance accounting and economics in theoretical models examining the effect of taxes

capital mobility and international sharing of cyclical risk this paper investigates whether the international globalization of financial markets allows for significant cross country risk sharing at the business cycle frequency we find that cross country risk sharing is still limited and this is unlikely to be the result of financial frictions that limit state contingent contracts part of the limited international risk sharing could be the consequence of frictions that de facto reduce the short term mobility of financial capital but even with these frictions we find significant divergence between model predictions and the data

the pricing of short term debt and the miller hypothesis a note in 1977 miller 2 challenged conventional wisdom concerning the gain from corporate leverage introducing an equilibrium model of the municipal and corporate debt markets and arguing that the effective personal tax rate on equity is negligible miller concluded that the relevant marginal tax rate operating across the two markets would be the corporate rate and as a result the marginal value of the tax shield to an individual firm would be zero the purpose of this paper is to present additional evidence regarding implied marginal tax rates on interest income taxable and tax free money market funds are compared making it possible to avoid difficulties in previous studies involving long term bond yields the results support the miller hypothesis when these short term rates are compared when there is little term structure impact and when risk differences are small observed returns on taxable and tax free investments imply a tax rate almost exactly equal to the corporate rate

municipal bond liquidity and default risk this paper examines the pricing of municipal bonds i use three distinct complementary approaches to decompose municipal bond spreads into default and liquidity components and find that default risk accounts for 74 to 84 of the average spread after adjusting for tax exempt status the first approach estimates the liquidity component using transaction data the second measures the default component with credit default swap data and the third is a quasi natural experiment that estimates changes in default risk around pre refunding events the price of default risk is high given the rare incidence of municipal default and implies a high risk premium

taxes default risk and yield spreads this paper develops a model of bond prices and yield spreads that incorporates the effect of both taxes and differences in default probabilities the tax loss consequences of default are recognized traditionally tax free municipal bond yields have been viewed as linearly related to taxable yields with a slope coefficient equal to one minus the tax rate and the intercept representing differences in default risk while our model supports the linearity assumption it implies that the slope and intercept are both functions of both the break even tax rate and the default probability ies clientele effects among both municipal and taxable bonds are demonstrated finally the implied marginal tax rates and the implied default probabilities are estimated for different categories of municipal bonds students of financial markets cannot help but be impressed by the number of new financial instruments that have been introduced successfully in recent years the fixed income market has been particularly innovative as bonds carrying a whole host of specific features have been successfully marketed bonds with small or zero coupons variable coupon rates or detachable warrants are three examples from among an expanding list of such features not surprisingly there has developed a large and expanding literature attempting to explain the rate spreads between different fixed income securities this literature has evolved much as one would expect early empirical work was in general not well founded in theory and was not based on an underlying expected return price model later empirical research has tended to be more careful in its specification of factors affecting yield spreads and as a consequence better founded in valuation

adopting knowledge from reverse innovations transnational patents and signaling from an emerging economy is there knowledge adoption of innovations from emerging economies we theorize that to help overcome information asymmetry across countries granting patents to technology in the emerging economy of china can serve as a signal of technology potential and market opportunity to enhance technological knowledge adoption in a developed economy such as the united states the effect may be greater in a complex technology sector with high information asymmetry than in a discrete technology sector and in regions with less developed market intermediaries where information asymmetry is high our difference in differences estimates using 4226 china u s patent dyads and comparable u s patents support our hypotheses

international business cycles the authors estimate a dynamic two country model in which economic fluctuations are driven by a worldwide supply shock country specific supply shocks and relative fiscal money and preference shocks identification is achieved using only long run restrictions based on a theoretical model the main results are 1 supply shocks particularly country specific ones are very important in generating international business cycles and 2 although the post 1973 flexible exchange rate period has been inherently more volatile there are no differences in transmission properties of economic disturbances across exchange rate regimes for the endogenous variables they focus on copyright 1993 by american economic association

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

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

was the tax exempt bond market inefficient or were future expected tax rates negative this paper shows that the sharp narrowing with maturity of the spread between taxable and tax exempt yields leaves room for tax arbitrage at times tax exempt forward rates have exceeded taxable forward rates at such times only expectations of higher taxes on treasury than on municipal bonds would eliminate profit opportunities the authors develop the idea of forward tax rates and compute forward tax rates for 1955 through 1984 they also outline tax arbitrage mechanisms involving private forward sale of long municipal bonds or the use of the municipal bond futures contract and show the potential profits the municipal yield curve has been upward sloping for the entire postwar period even at times when taxable yield curves were humped or downward sloping thus the spread in yields between taxable and tax free bonds narrows dramatically with increasing maturity this paper focuses on the term structure of the spread in yields between taxable and tax exempt bonds we show that the sharp narrowing of the spread with maturity leaves room for some apparently unexploited tax arbitrage at times the narrowing has been so dramatic that taxexempt forward rates have exceeded taxable forward rates in other words only expectations of negative future tax rates on treasury interest or the expectations of a reversal in the relative taxability of treasury and municipal bonds would eliminate profit opportunities this situation makes little sense if the markets are well arbitraged three theories of the relationship between the yields on taxable and taxexempt bonds have attracted attention 2 miller 8 asserts that the corporate tax rate determines the yield spread between taxable and tax exempt debt in the

market segmentation and the term structure of municipal yields an issue of considerable controversy in recent years is whether segmentation exists in the municipal bond market the presence of market segmentation suggests that securities can be subdivided into distinct groups according to some characteristic and there exists a lack of substitution between these groups on the part of borrowers and or investors 1 4 8 hendershott and kidwell 4 for example found evidence that market segmentation affected yields between regionally and nationally marketed municipal bond issues others contend that the municipal bond market is relatively efficient and no permanent segmentation effects can exist 2 9 most recently campbell 2 examined possible segmentation resulting from the large acquisitions of municipal securities by commercial banks and found that bank demand for municipal securities had no significant influence on the yield spreads between municipal bonds which differed in default risk term to maturity and tax treatment this is consistent with the argument that the combination of progressive personal income tax rates and fixed corporate income tax rates induces corporations to issue an amount of debt such that the marginal investor in taxable and tax exempt securities pays taxes at the full corporate rate 9 if segmentation does not exist two peculiar features of the term structure of municipal yields cannot be fully explained for one municipal yields have almost always increased monotonically with maturity this is true both for market averages of similarly rated municipal securities and for reoffering yields on individual serial

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

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

auction failures and the market for auction rate securities abstract the market for auction rate securities ars made headlines during the second week of february 2008 when auctions at which the bonds interest rates reset experienced a wave of failures contrary to headlines that attribute the failures to a frozen market or investors irrationality we find that 1 even at their height less than 50 of ars experienced auction failures 2 the likelihood of auction failure was directly related to the level of the bonds maximum auction rates 3 the implied market clearing yields of bonds with failed auctions were significantly above their maximum auction rates and 4 ars yields were generally higher than yields of various cash equivalent investment alternatives we infer that investors priced the possibility of auctions failures into ars yields and rationally declined to bid for bonds for which required market yields exceeded their maximum auction rates

financial integration and international risk sharing abstract conventional wisdom suggests that financial liberalization can help countries insure against idiosyncratic risk there is little evidence however that countries have increased risk sharing despite widespread financial liberalization we show that the key to understanding this puzzling observation is that conventional wisdom assumes frictionless international financial markets while actual markets are far from frictionless financial contracts are incomplete and contract enforceability is limited when countries remove official capital controls default risk is still present as an implicit barrier to capital flows if default risk were eliminated capital flows would be six times greater and international risk sharing would increase substantially

one way arbitrage foreign exchange and securities markets a note theorem in the case of traders with exogenous needs to acquire foreign currency recently deardorff 3 coitned the phrase one way arbitrage to describe the behavior of those traders and showed that it probably precludes round trip covered interest arbitrage from breaking even deardorff s analysis focuses on the conditions under which in the presence of transaction costs there would be both spot and forward transactions on the foreign exchange markets at equilibrium in this paper we extend the analysis to derive the conditions under which transactions would exist in both the home and foreign securities markets and we generalize the results to the case of transactions in all markets

asset pricing puzzles and incomplete markets the representative agent theory of asset pricing is modified to incorporate heterogeneous agents and incomplete markets the model features two types of agents who differ up to a nontradable idiosyncratic component in their endowment processes numerical solutions indicate that individuals are able to diversify a substantial portion of their idiosyncratic income risk through riskless borrowing and lending alone restrictions on the variability of intertemporal marginal rates of substitution hansen and jagannathan 1991 are used to argue that incomplete markets as modeled here cannot account for the properties of asset returns that are anomalous from the perspective of representative agent theory a large literature in financial economics has investigated the extent to which variants of the lucas 1978 general equilibrium theory of asset pricing can account for the joint behavior of aggregate u s consumption and asset returns by and large this literature has concluded that a theory based upon frictionless arrow debreu markets and or a representative agent makes strongly counterfactual predictions regarding even the simple unconditional properties of this relationship mehra and prescott 1985 for instance show that the theory drastically underpredicts the average excess rate of return on u s stocks the so called equity premium puzzle weil 1989 points out as did mehra and prescott that the magnitude of the average risk free rate is far below that predicted by the theory this has been dubbed the risk free rate puzzle numerous authors including grossman melino and shiller 1987 and backus gregory and zin 1989 show that the theory cannot account for term premia inherent in the yield curve hodrick 1987 surveys a large literature which documents the theory s shortcomings in accounting for excess expected returns in foreign exchange markets the notion that the representative agent model cannot account for excess returns across a wide array of asset markets can be made more precise by using tools developed by hansen and jagannathan 1991 and shiller 1982

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

financial integration entrepreneurial risk and global dynamics abstract how does financial integration impact capital accumulation current account dynamics and cross country inequality we investigate this question within a two country general equilibrium incomplete markets model that focuses on the importance of idiosyncratic entrepreneurial risk a risk that introduces not only a precautionary motive for saving but also a wedge between the interest rate and the marginal product of capital our contribution is to show that this friction provides a simple explanation for the emergence of global imbalances a resolution to the empirical puzzle that capital often fails to flow from the rich or slow growing countries to the poor or fast growing ones and a set of policy lessons regarding the intertemporal costs and benefits of capital account liberalization

bond returns liquidity and missing data this paper examines holding period returns to constant duration portfolios of u s govern ment notes and bonds and measures the return premium generated by liquidity differences in bonds the approach compares constant duration portfolios constructed in two distinct ways one using only bonds issued in the most recent treasury auction one using all other bonds comparisons of the resulting series are made meaningful by choosing narrow du ration ranges in the portfolio formation procedure this in turn induces a missing data problem in the created time series parameters of return distributions are therefore estimated employing a maximum likelihood framework that explicitly accounts for the missing data it is estimated that recently issued bonds are priced to return a premium of around 55 basis points per annum over otherwise equivalent instruments

real interest rates home goods and optimal external borrowing the paper investigates the optimal time path of consumption and external borrowing in the dependent economy model the small country faces given world prices and a given world real interest rate the presence of a home goods sector implies that the relevant real interest rate appropriate to consumption decisions depends on the rate of change of the real price of home goods the paper shows how transitory disturbances in output or in the world real interest rate affect the time profile of consumption and the trade balance in particular it is shown that the presence of a home goods sector dampens the consumption effects of changes in the world interest rate

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

tax subsidized underpricing the market for build america bonds build america bonds babs were issued by municipalities for 20 months as a part of the 2009 fiscal package unlike traditional tax exempt municipals babs are taxable to the holder but the treasury rebates 35 of the coupon to the issuer the stated purpose was to provide municipalities access to a more liquid market including foreign tax exempt and tax deferred investors we find babs do not exhibit greater liquidity than traditional municipals babs are more underpriced initially particularly for interdealer trades babs also show a substitution from underwriter fees toward more underpricing suggesting that the underpricing is a strategic response to the tax subsidy

tax distortions and bond issue pricing abstract original issue premium oip bonds are the norm in the us tax exempt market but very rare in the taxable market a tax subsidy helps explain this disparity unlike bonds issued at par or discount the price of oip bonds can fall and yet remain above par providing secondary market buyers with more tax exempt coupon and less taxable market discount gain the subsidy for oip bonds explains additional previously undocumented empirical facts in a calibration exercise the subsidy s expected cost to the u s treasury is estimated at 1 7 billion per year

a simple model of the taxable and tax exempt yield curves i examine the anomalous behavior of the taxable and tax exempt yield curves long municipal yields appear too high relative to the equivalent after tax yield that can be earned in treasury or corporate bonds i discuss existing explanations of the problem and propose a simple model that relates the yields of taxable bonds to the yield curve for par tax exempts the ratio of the tax exempt yield to the taxable yield increases with maturity in the model so it is consistent with observed phenomena such as inverted yield curves for taxables and contemporaneous rising yield curves for tax exempts statistical and descriptive comparisons between the yields predicted by the model and observed yields on par bonds that the model has some promise in explaining the apparent anomalies in the behaviors of the two yield curves article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies
