a panel cointegration analysis of the demand for oil in the middle east this article applies recently developed panel unit root and panel cointegration techniques to estimate the long run income and price elasticities for oil in the middle east the results for the panel indicate that demand for oil is highly price inelastic and slightly income elastic in the middle east there is considerable variation in the results for the income variable across countries with the coefficient on the income variable statistically insignificant for several countries the coefficient on the price variable is statistically significant in all cases with the expected sign and the price elasticity is uniformly low while the results for the income variable differ across countries the results for the panel as a whole suggest that the demand for oil in the middle east is being driven largely by strong economic growth while consumers are largely insensitive to price changes

subjective stochastic dominance put writing and stock purchases with extensions to option pricing and portfolio composition initially an investor has the choice of two risky assets writing a european put option or buying the underlying share under broad conditions a risk averse investor will be subjectively better off writing the put when homogeneous expectations are invoked an upper bound for the put premium is obtained a numerical example using the lognormal density function illustrates the broad conditions for risk averters subjectively preferring the put writing strategy additional conditions permit this preference for writing puts to be extended to the portfolio context transactions costs only reinforce this preference in the one period horizon considered

financial integration and business cycles in a small open economy abstract the purpose of this study is to examine a dynamic stochastic general equilibrium framework with financial and informational frictions and foreign borrowing in the case of money growth and technology shocks for a small open economy and to analyze the implications of varying degrees of financial integration for aggregate fluctuations and propagation mechanisms in the economy the existence of informational asymmetries among the agents in the model necessitates financial intermediation in the economy moreover there is uncertainty involved in the production process which leads to collateralized borrowing by firms and therefore has to be taken into account in the design of the loan contracts between firms and financial intermediaries it is shown that increasing financial integration amplifies the effect of a positive temporary monetary shock on output consumption investment labor demand and loans whereas it has barely any implication for the impact of a positive temporary technology shock on the economy

the incidence and allocation effects of a tax on corporate distributions abstract to study the effects of double taxation first at the corporation level then at the shareholder level this paper analyzes a model with a tax on all corporate distributions to equity owners and no other taxes contrary to the common view the tax is shown to have no subtitution effect and in particular no effect on the corporate choice between debt and equity via retained earnings finance the analysis opens to question certain arguments commonly used to support integration of corporation and individual income taxes via dividend relief

pricing american interest rate claims with humped volatility models abstract some of the most recent empirical studies on interest rate derivatives have found humped shapes in the volatility structure of interest rates in this paper we propose a simple model that allows for humped volatility structures and that can be described by one state variable with the model american style claims can be priced very efficiently which is very important if the model has to be calibrated daily to market prices of standard american options furthermore the model allows for explicit formulas for european style options finally the computational efficiency of our model in the li et al 1995 framework is compared with the efficiency in a typical hull and white 1993a 1994 1996 framework in fact we can use both procedures for our model since we prove that if a deterministic volatility model can be embedded in either of these algorithms then so it does in the other one empirical evidence from option data supporting our model is provided as well

on the firm s production capital structure and demand for debt some economists have ignored corporate financing decisions on the assumption that they do not affect the investment and production decisions of firms yet even if this extreme position is accepted firms must still make financing decisions which in turn have impacts on other sectors of the economy since interest payments on corporate debt are tax deductible the reliance of firms on debt as opposed to equity financing directly affects the revenue the federal government collects through taxation of corporate profits the corporate presence in bond markets and corporate borrowing from banks can be expected to affect both interest rates and the demand for money thus any large macro model must somehow account for the borrowing behavior of firms yet in assessing this portion of the 1965 brookings quarterly econometric model of the united states de leeuw 1965 p 506 writes that the regressions for business borrowing are the least successful of the model in this paper we derive an equation for the long term debt ratio capital structure of a firm which can be estimated using available data unlike some recent qualitative studies on the aggregate corporate debt ratio as related to inflation and taxation over time our primary aim is to explain differences in the debt behavior among individual firms tobit estimation results explicitly allowing for the fact that some firms have no long term debt are presented for both u s and japanese firms our theoretical model implies that the long term debt ratio which maximizes the present value of the existing stockholder s equity depends positively on the cost of equity and negatively on the cost of debt capital productivity and retained earnings our estimation results are generally in agreement with these expectations in particular we find that capital productivity which has not been included as an explanatory variable in most previous studies 2 and the cost of equity capital are both important determinants of the firm s capital structure our empirical results also support the view put forward by komiya3 that debt ratios for japanese firms are higher than those for u s firms in part because the cost of equity has been historically higher in japan than in the united states in relation to the cost of debt other important attempts to explain the debt ratio as a behavioral function of the price of debt and other variables include the studies of de leeuw 1965 and goldfeld 1969 4 certain conceptual problems mar these studies however short term and long term debt are not distinguished despite the fact that long term debt is usually used to finance capital spending while short term debt is used to finance inventory and

bond pricing and the term structure of interest rates a new methodology for contingent claims valuation this paper presents a unifying theory for valuing contingent claims under a stochastic term structure of interest rates the methodology based on the equivalent martingale measure technique takes as given an initial forward rate curve and a family of potential stochastic processee for its subsequent movements a no arbitrage condition restricts this family of processes yielding valuation formulae for interest rate sensitive contingent claims which do not explicitly depend on the market prices of risk examples are provided to illustrate the key results in relation to the term structure of interest rates arbitrage pricing theory has two purposes the first is to price all zero coupon default free bonds of varying maturities from a finite number of economic fundamentals called state variables the second is to price all interest rate sensitive contingent claims taking as given the prices of the zero coupon bonds this paper presents a general theory and a unifying framework for understanding arbitrage pricing theory in this context of which all existing arbitrage pricing models are special cases in particular vasicek 1977 brennan and schwartz 1979 langetieg 1980 ball and torous 1983 ho and lee 1986 schaefer and schwartz 1987 and artzner and delbaen 1988 the primary contribution of this paper however is a new methodology for solving the second problem i e the pricing of interest rate sensitive contingent claims given the prices of all zero coupon bonds the methodology is new because i it imposes its stochastic structure directly on the evolution of the forward rate curve ii it does not require an inversion of the term structure to eliminate the market prices of risk from contingent claim values and iii it has a stochastic spot rate process with multiple stochastic factors influencing the term structure the model can be used to consistently price and hedge all contingent claims american or european on the term structure and it is derived from necessary and more importantly sufficient conditions for the absence of arbitrage the arbitrage pricing models of vasicek 1977 brennan and schwartz 1979 langetieg 1980 and artzner and delbaen 1988 all require an iformerly titled bond pricing and the term structure of interest rates a new methodology

an analytically tractable interest rate model with humped volatility abstract some of the most recent empirical studies on interest rate derivatives have found humped shapes in the volatility structure of interest rates however this realistic feature has been hardly addressed in theoretical works in this paper we propose an interest rate model which allows for a humped volatility structure and which is analytically tractable in that it leads to explicit formulae for european options on discount bonds empirical evidence supporting the model is also provided

institutional investment patterns and corporate financial behavior in the united states and japan abstract this paper examines the agency problem between shareholders and debtholders of japanese and u s firms whereas u s institutional investors are restricted from doing so japanese financial institutions take large equity positions in firms to which they lend particularly in firms more susceptible to the agency problem debt ratios of u s firms are negatively related to the firm s potential to engage in risky suboptimal investments whereas japanese debt ratios show no such relation the evidence is consistent with the notion that the agency problem is mitigated to a greater degree in japan than in the u s

kriging of financial term structures due to the lack of reliable market information building financial term structures may be associated with a significant degree of uncertainty in this paper we propose a new term structure interpolation method that extends classical spline techniques by additionally allowing for quantification of uncertainty the proposed method is based on a generalization of kriging models with linear equality constraints market fit conditions and shape preserving conditions such as monotonicity or positivity no arbitrage conditions we define the most likely curve and show how to build confidence bands the gaussian process covariance hyper parameters under the construction constraints are estimated using cross validation techniques based on observed market quotes at different dates we demonstrate the efficiency of the method by building curves together with confidence intervals for term structures of ois discount rates of zero coupon swaps rates and of cds implied default probabilities we also show how to construct interest rate surfaces or default probability surfaces by considering time quotation dates as an additional dimension

a tractable interest rate model with explicit monetary policy rates abstract this paper proposes a novel interest rate model that presents simple analytical pricing formulas for interest rate based derivatives including swaps futures swaptions caps and floors exploring the regime switching feature of markov chains the proposed model focuses on discrete changes in the central bank policy rates the main driver of short term rate fluctuations an empirical analysis shows that the proposed model generally outperforms other standard short term rate models in fitting cross sections of options prices moreover the explicit nature of policy rates to some extent enables the model to infer risk neutral probabilities of the central bank rate decisions

an empirical analysis of energy demand in namibia abstract using a unique database of end user local energy data and the recently developed autoregressive distributed lag ardl bounds testing approach to cointegration we estimate the long run elasticities of the namibian energy demand function at both aggregated level and by type of energy electricity petrol and diesel for the period 1980 2002 our main results show that energy consumption responds positively to changes in gdp and negatively to changes in energy price and air temperature the differences in price elasticities across fuels uncovered by this study have significant implications for energy taxation by namibian policy makers we do not find any significant cross price elasticities between different fuel types

estimation of short run and long run elasticities of energy demand from panel data using shrinkage estimators this article discusses the problem of obtaining short run and long run elasticities of energy demand for each of 49 states in the united states using data for 21 years estimation using the time series data by each state gave several wrong signs for the coefficients estimation using pooled data was not valid because the hypothesis of homogeneity of the coefficients was rejected shrinkage estimators gave more reasonable results the article presents in a unified framework the classical empirical bayes and bayes approaches for deriving these estimators

direct evidence on the marginal rate of taxation on dividend income abstract miller and scholes 1978 hypothesize that the marginal tax rate on dividend income may be less than the marginal rate of tax on capital gains their hypothesis is dependent upon individuals utilizing existing provisions of the code which serve to reduce the taxation of dividends in this study estimates of the marginal and effective rates of tax on dividend income for the year 1979 are presented using the statistics of income sample of returns the average marginal rate of tax on dividend income is estimated to be 40 while the average effective rate of tax is estimated to be 30

pricing caps with hjm models the benefits of humped volatility in this paper we compare different multifactor hjm models with humped volatility structures to each other and to models with strictly decreasing volatility all the models are estimated on euribor and swap rates panel data maximizing the quasi likelihood function obtained from the kalman filter we develop the analysis in two steps first we study the in sample properties of the estimated models then we test the pricing performance on caps we find the humped volatility specification to greatly improve the model estimation and to provide sufficiently accurate cap prices although the models has been calibrated on interest rates data and not on cap prices moreover we find the two factor humped volatility model to outperform the three factor models in pricing caps

demand for gasoline in the gcc an application of pooling and testing procedures the structure of gasoline demand in the gcc countries was analysed the aim was to estimate price and income elasticities both for the short and long run it was found that gasoline demand is inelastic with respect to both price and income for both the short and long run when gcc countries were divided into two groups based on their pricing policies it was found that the group with the free market approach and higher reliance on market forces gave larger price elasticities and smaller income elasticities in both the short run and long run

international capital structure equilibrium this paper develops a theory of capital structure in an international setting with corporate and personal taxes we generalize the miller analysis to an international equilibrium characterized by differential international taxation and inflation in otherwise perfect international capital markets our analysis highlights the key role that corporate tax arbitrage plays in generating an international capital structure equilibrium and we set forth a number of mechanisms for tax arbitrage transactions we close the paper by outlining some implications of our analysis for national differences in capital structure the international fisher effect and international tax effects on yield differentials among major questions regarding corporate capital structure which arise in an international setting are how or whether multiple tax jurisdictions and multiple currencies affect firm financing decisions and the international bond market equilibrium we examine some of these questions by way of generalizing miller s 1977 debt and taxes model into an international setting this setting allows for different tax regimes across countries as well as the possibility of differential inflation across currencies with consequent exchange rate movements in the first part of this paper we find that an international miller type equilibrium obtains under differential international taxation with capital market conditions which are otherwise analogous to those required for a domestic miller equilibrium our analysis particularly highlights the role that corporations play in miller s analysis as vehicles for tax arbitrage we show that if corporations engage in international tax arbitrage transactions on an equal footing no optimal capital structure exists for individual firms consequently without further restrictions differences in international tax rates alone are incapable of dictating a particular capital structure for an individual firm in the second part of the paper we extend the analysis to consider differential inflation rates with a consequent exchange rate movement and draw additional implications for the international analog of the miller equilibrium with differential inflation and taxation we begin by showing the existence of the international fisher effect for both equity and bonds although inflation and or exchange rate movements may affect real corporate tax subsidy rates and real

an empirical analysis of gasoline demand in denmark using cointegration techniques abstract danish time series data covering the period 1948 1991 are used in order to estimate short run and long run elasticities in gasoline demand a cointegration test for a stable long run relationship between the variables in the model proves to be positive showing a smaller value of the long run price elasticity than often quoted in empirical studies of gasoline demand finally an error correction model is estimated

empirical assessment of the determinants of road energy demand in greece this paper attempts to cast light on the determinants of road energy demand in greece for this purpose we used cointegration techniques and vector autoregression var analysis in order to capture short run and long run dynamics for gasoline and diesel demand respectively from the empirical analysis that covers the period 1978 2003 we find that in the long run gasoline energy demand appears to be price and income inelastic while diesel demand appears to be price inelastic and income elastic we also found that the absence of close substitutes in the road sector denotes the low level of energy switching in greece

term structure movements and pricing interest rate contingent claims this paper derives an arbitrage free interest rate movements model ar model this model takes the complete term structure as given and derives the subsequent stochastic movement of the term structure such that the movement is arbitrage free we then show that the ar model can be used to price interest rate contingent claims relative to the observed complete term structure of interest rates this paper also studies the behavior and the economics of the model our approach can be used to price a broad range of interest rate contingent claims including bond options and callable bonds

the demand for gasoline in south africa an empirical analysis using co integration techniques abstract using the recently developed autoregressive distributed lag ardl bound testing approach to co integration suggested by pesaran et al pesaran m h shin y smith r j bounds testing approaches to the analysis of level relationships journal of applied econometrics 2001 16 3 289 326 we empirically analyzed the long run relationship among the variables in the aggregate gasoline demand function over the period 1978 2005 our study confirms the existence of a co integrating relationship the estimated price and income elasticities of 0 47 and 0 36 imply that gasoline demand in south africa is price and income inelastic

debt agency costs and industry equilibrium we show that risk characteristics of projects cash flows are endogenously determined by the investment decisions of all firms in an industry as a result in reasonable settings financial structures which create incentives to expropriate debtholders by increasing risk are shown not to reduce value in an industry equilibrium without taxes capital structure is irrelevant for individual firms despite its effect on the equityholders incentives but the maximum total amount of debt in the industry is determinate allowing for a corporate tax advantage of debt capital structure becomes relevant but firms are indifferent between distinct alternative debt levels the effect of firms financial structures on subsequent investment and output decisions has recently received considerable attention in the finance literature the central insight that equityholders control the firm s investment and production decisions and in general do not maximize the value of a levered firm has been applied to the analysis of risk shifting underinvestment and firms abilities to enter into optimal contracts with their customers existing models of firms financial structures and their effect on investment decisions are generally based on a single firm framework and do not take into account the relationship between project cash flows and the investment decisions of all firms in the industry 2 in this paper we allow the distribution of investment projects within an industry to adjust and show that this generates new insights and reverses several key results of single firm agency cost models the new predictions conform with well documented

why do companies pay dividends this paper presents a simple model of market equilibrium to explain why firms that maximize the value of their shares pay dividends even though the funds could instead be retained and subsequently distributed to shareholders in a way that would allow them to be taxed more favorably as capital gains the two principal ingredients of our explanation are 1 the conflicting preferences of shareholders in different tax brackets and 2 the shareholders desire for portfolio diversification we show that companies will pay a positive fraction of earnings in dividends we also provide some comparative static analysis of dividend behavior with respect to tax parameters and to the conditions determining the riskiness of the securities this abstract was borrowed from another version of this item

debt and taxes abstract the extreme reliance on debt that has been a persistent feature of corporate finance in contemporary japan is at least partially due to low personal tax rates this statement is supported by comparison of japan and u s taxes based on the taxes and failure cost theory of finance

the market valuation of cash dividends abstract this paper re examines the case of citizens utilities a firm with one class of common stock which pays stock dividends and one which pays taxable cash dividends john long s 1978 study of the two shares relative prices suggests that investors may prefer cash dividends to equal sized stock dividends this paper finds that the cash dividend share s ex day price decline is less than their dividend payment stock dividend shares fall by nearly their full dividend the disparity between ex day dividend valuation and the observed prices of the two shares is inconsistent with some explanations of the demand for cash dividends

a comparison of the labor force behavior of married women in the united states and canada with special attention to the impact of income taxes estimation results are presented for the probability of working the hourly wage rate and the annual hours of work for wives in seven different age groups in both the u s and canada federal and state or provincial taxes are incorporated into the analysis an iterative estimation method is employed to circumvent the statistical problems resulting from the dependence of the hours of work on the tax rate and the dependence of the tax rate on the hours of work authors

dynamic factor demands and the effects of energy price shocks a dynamic model is used to understand how sharp changes in energy prices affect investment behavior employment and energy use the authors discuss the theory behind their model selection model specifications estimation methods and data list parameter estimates and elasticities for the selected model and describe the simulations they conclude that 1 the data strongly reject the hypothesis of constant returns to scale within their specification of aggregate production 2 the data indicate adjustment costs on labor are small and 3 their results help reconcile some of the conflicting estimates of energy demand elasticities appearing in recent literature 23 references 3 figures 3 tables

a cyclical square root model for the term structure of interest rates this paper presents a cyclical square root model for the term structure of interest rates assuming that the spot rate converges to a certain time dependent long term level this model incorporates the fact that the interest rate volatility depends on the interest rate level and specifies the mean reversion level and the interest rate volatility using harmonic oscillators in this way we incorporate a good deal of flexibility and provide a high analytical tractability under these assumptions we compute closed form expressions for the values of different fixed income and interest rate derivatives finally we analyze the empirical performance of the cyclical model versus that proposed in cox et al 1985 and show that it outperforms this benchmark providing a better fitting to market data

metaanalisis de las elasticidades ingreso y precio de la demanda de energia algunas implicaciones de politica publica para america latina the aim of this paper is to analyze the variation in empirical estimates of the income and price elasticities of energy demand the evidence presented through a meta analysis allows identification of the weighted average of the income and price elasticities shows that the estimates are very heterogeneous that there is publication bias and that factors such as region energy sector among others affect its volatility the evidence also indicates that income elasticity in latin america is greater than in the oecd countries and that the price elasticity of energy demand is lower in latin america than in the oecd countries therefore continued economic growth in latin america will be accompanied by a growth in energy demand moreover the establishment of a tax in latin america under the current elasticities is less effective and will be insufficient to control the increase in energy consumption

does the investment interest limitation explain the existence of dividends abstract miller and scholes have shown that under certain conditions the federal income tax taxes dividend income at a rate no higher than the rate on capital gains tabulations of actual 1977 tax returns show that the special circumstances under which this can occur apply to recipients of two and one half percent of dividend income and that no dominant role may therefore be ascribed to their hypothesis in the determination of corporate dividend policy

sectoral demand for petroleum in thailand this paper examines the short run and long run determinants of final oil consumption in seven major economic sectors in thailand two different approaches are compared the first approach uses dynamic panel data estimation techniques taking into account oil consumption of the whole economy in an aggregate manner the second approach employs the adl equilibrium correction framework to model oil demand in each economic sector separately the dynamic panel data approach estimates appear consistent with economic theory the coefficients have the correct signs and the magnitudes of long run responses are larger than the short run responses the single sector model approach yields similar but richer results relaxing the identical slope assumption reveals interesting sector specific characteristics

an exact bond option formula this paper derives a closed form solution for european options on pure discount bonds assuming a mean reverting gaussian interest rate model as in vasicek 8 the formula is extended to european options on discount bond portfolios

the nature of oil shocks and the global economy abstract this paper identifies the main driving force behind oil price shocks in 1970 2006 by applying a simple identification strategy of supply driven and demand driven price shocks the identification hypothesis states that supply driven oil price shocks have a negative impact on the macroeconomic activity of countries which are net consumers of oil while demand driven oil price shocks do not have negative effects in order to identify global demand driven shocks a weighted aggregate gdp series of countries which are net consumers of oil is constructed over 1970 2006 the key result is that the main driving force behind oil price shocks has changed from supply driven shocks in 1970 1992 to demand driven shocks in 1992 2006

short and long run effects between oil consumption and economic growth in china this paper examines both the equilibrium relationship and the predictability between oil consumption and economic growth in china time series variables are employed in empirical tests cointegration tests suggest that these two variables tend to move together in the long run in addition granger causality tests indicate that oil consumption could be a useful factor that forecasts changes in the economy in the short run as well as in the long run the oil consumption is found to have great effects on the economy this is because the enormous use of oil in sectors like the industry may have directly pushed the economy however this finding would probably stimulate faster growth in oil consumption and so should be concerned with care conversely economic growth could be used as a predictive factor forecasting oil consumption only in the long run economic growth appears to have small effects on oil use this could be attributed largely to china s energy consumption structure coal constitutes most of the energy consumption and thus the considerable demand for energy resulting from rapid economic growth could be mostly explained by the mass use of coal

the performance of alternative interest rate risk measures and immunization strategies under a heath jarrow morton framework using a monte carlo simulation this study addresses the question of how traditional risk measures and immunization strategies perform when the term structure evolves in a heath jarrow morton 1992 manner the results suggest that for immunization purposes im munization strategies and portfolio formation strategies are more important than interest rate risk measures the performance of immunization strategies depends more on the transaction costs and the holding period than on the risk measures moreover the immu nization performance of bullet and barbell portfolios is not very sensitive to interest rate risk measures

implied volatility functions in arbitrage free term structure models abstract we test six term structure models in the heath jarrow and morton 1992 class using eurodollar futures and options data from 1987 1992 we study the time series of implied interest rate volatilities from these models using one day lagged implied volatilities our one and two parameter models simultaneously price an average of 18 5 options each day with an average absolute error of one and a half to two basis points although the models fit well we document systematic strike price and time to maturity biases for all models we also implement simple trading strategies to test whether the models identify genuine biases
