tax benefits of leasing financial economists view the tax benefits of leasing as transaction specific functions of the tax effects of rents depreciation and interest attributed to lessors and lessees facing different tax rates we offer two conceptual ways to characterize those tax benefits

determinants of corporate leasing policy the existing finance literature assumes the real operating cash flows from leasing or owning are invariant to the ownership of the asset and focuses on tax related incentives for corporate leasing policy our analysis suggests that taxes are important in identifying potential lessees and lessors but are less important in identifying the specific assets leased we provide a unified analysis of the various incentives affecting the lease versuspurchase decision we then show how these incentives explain the use of contractual provisions such as maintenance clauses deposits options to purchase the asset and metering when a firm buys an asset it obtains both the right to the services of that asset over the period it is owned plus the right to sell the asset at any future date with a lease the firm acquires only the right to the asset s services for a period specified in the contract the existing finance literature analyzing corporate leasing policy concentrates on the tax related incentives to lease or buy e g see miller and upton 19 myers et al 21 lewellen et al 13 franks and hodges 11 and brealey and young 4 we believe that taxes play an important role in explaining certain dimensions of leasing policy for example the choice between manufacturer and third party leasing however taxes provide only a limited explanation of why specific assets are leased rather than owned and for the choice of provisions in lease contracts in this paper we want to accomplish two things 1 to provide a unified analysis of the various incentives affecting the lease versus buy decision and 2 to employ that analysis to explain observed variation in corporate leasing policy in deriving testable hypotheses about the characteristics of lessees lessors the assets leased and provisions in lease contracts we extend the standard leaseversus buy analysis found in corporate finance textbooks e g brealey and myers

what does tax aggressiveness signal evidence from stock price reactions to news about tax shelter involvement abstract we study the stock price reaction to news about corporate tax aggressiveness we find that on average a company s stock price declines when there is news about its involvement in tax shelters we find some limited evidence for cross sectional variation in the reaction for example the reaction is more negative for firms in the retail sector suggesting that part of the reaction may be a consumer taxpayer backlash in addition the reaction is less negative for firms that are viewed to be generally less tax aggressive as proxied by the firm s cash effective tax rate we interpret this as being consistent with the market reacting positively to evidence that a firm is trying to reduce taxes when their financial reports would lead one to believe the firm is not tax aggressive

research in accounting for income taxes abstract this paper comprehensively reviews the accounting for income taxes afit literature we begin by identifying four distinctive aspects of afit and briefly covering the rules surrounding afit we then review the existing studies in detail and offer suggestions for future research we emphasize the research questions that have been addressed most of which relate to whether the tax accounts are used to manage earnings and whether the tax accounts are priced by equity market participants we also highlight areas that have not received much research attention and that warrant future analysis

investment ramifications of distortionary tax subsidies abstract this paper examines the investment effects of tax subsidies for which some assets and not others are eligible distortionary tax subsidies concentrate investments in tax favored assets thereby reducing the expected pre tax profitability of investment and reducing payoffs to bondholders in the event of default anticipation of asset substitution encourages lenders to require covenants in debt contracts which only imperfectly address asset substitution and distort investment the result is that borrowing is made more expensive which in turn discourages investment borrowing rates can react so strongly that aggregate investment may rise very little or even fall in response to higher tax subsidies debt issued by u s firms in risk of default after the 2002 introduction of bonus depreciation for u s equipment investment contained many more covenants than in other periods a pattern that reversed when bonus depreciation was discontinued after 2004 furthermore firms at risk of default borrowed less and were more apt to lease capital than were other firms during the bonus depreciation period

from measure changes to time changes in asset pricing abstract the goal of the paper is to review the last 35 years of continuous time finance by focusing on two major advances i the powerful elegance of the martingale representation for primitive assets and attainable contingent claims in more and more general settings thanks to the probabilistic tool of probability change and the economic flexibility in the choice of the numeraire relative to which prices are expressed this numeraire evolved over time from the money market account to a zero coupon bond or a stock price lastly to strictly positive quantities involved in the libor or swap market models and making the pricing of caps or swaptions quite efficient ii the persistent central role of brownian motion in finance across the 20th century even when the underlying asset price is a very general semi martingale the no arbitrage assumption and monroe theorem monroe i 1978 processes that can be embedded in brownian motion annals of probability 6 42 56 allow us to write it as brownian motion as long as we are willing to change the time the appropriate stochastic clock can be shown empirically to be driven by the cumulative number of trades hence by market activity consequently starting with a general multidimensional stochastic process s defined on a probability space f f t p and representing the prices of primitive securities the no arbitrage assumption allows for any chosen numeraire to obtain a martingale representation for s under a probability measure qs equivalent to p this route will be particularly beneficiary for the pricing of complex contingent claims alternatively changing the clock i e changing the filtration f t we can recover the brownian motion and normality of returns in all cases martingales appear as the central representation of asset prices either through a measure change or through a time change

do taxes affect corporate debt policy evidence from us corporate tax return data abstract this paper uses u s statistics of income soi corporate income tax returns balance sheet data on all corporations to estimate the effects of changes in corporate tax rates on the debt policies of firms of different sizes small firms face very different tax rates than larger firms and relative tax rates have also changed frequently over time providing substantial information to identify tax effects the results suggest that taxes have had a strong and statistically significant effect on debt levels for example cutting the corporate tax rate by ten percentage points e g from 46 to 36 holding personal tax rates fixed is forecast to reduce the fraction of assets financed with debt by around 3 5 since small firms normally rely much more heavily on debt finance yet face much lower tax incentives to use debt the estimated effect of taxes would be strongly biased downwards without controls for firm size

are firms underleveraged an examination of the effect of leverage on default probabilities a commonly held view in corporate finance is that firms are less leveraged than they should be given the potentially large tax benefits of debt in this paper i study the effect of firms leverage on default probabilities as represented by the firms ratings using an instrumental variable approach i find that the leverage s effect on ratings is three times stronger than it is if the endogeneity of leverage is ignored this stronger effect results in a higher impact of leverage on the ex ante costs of financial distress which can offset the current estimates of the tax benefits of debt

on the existence of an optimal capital structure theory and evidence one of the most contentious issues in the theory of finance during the past quarter century has been the theory of capital structure the geneses of this controversy were the seminal contributions by modigliani and miller 18 19 the general academic view by the mid 1970s although not a consensus was that the optimal capital structure involves balancing the tax advantage of debt against the present value of bankruptcy costs no sooner did this general view become prevalent in the profession than miller 16 presented a new challenge by showing that under certain conditions the tax advantage of debt financing at the firm level is exactly offset by the tax disadvantage of debt at the personal level since then there has developed a burgeoning theoretical literature attempting to reconcile miller s model with the balancing theory of optimal capital structure e g deangelo and masulis 5 kim 12 and modigliani 17 the general result of this work is that if there are significant leverage related costs such as bankruptcy costs agency costs of debt and loss of non debt tax shields and if the income from equity is untaxed then the marginal bondholder s tax rate will be less than the corporate rate and there will be a positive net tax advantage to corporate debt financing the firm s optimal capital structure will involve the trade off between the tax advantage of debt and various leverage related costs the upshot of these extensions of miller s model is the recognition that the existence of an optimal capital structure is essentially an empirical issue as to whether or not the various leverage related costs are economically significant enough to influence the costs of corporate borrowing the miller model and its theoretical extensions have inspired several timeseries studies which provide evidence on the existence of leverage related costs trczinka 28 reports that from examining differences in average yields between taxable corporate bonds and tax exempt municipal bonds one cannot reject the miller hypothesis that the marginal bondholder s tax rate is not different from the corporate tax rate however trczinka is careful to point out that this finding does not necessarily imply that there is no tax advantage of corporate debt if the personal tax rate on equity is positive indeed buser and hess 1 using a longer time series of data and more sophisticated econometric techniques estimate that the average effective personal tax rate on equity is statistically positive and is not of a trivial magnitude more importantly they document evidence that is consistent with the existence of significant leverage related costs in the economy

comments on the valuation of derivative assets abstract this paper presents an alternative approach to derive the breeden litzenberger valuation formula which expresses the price of an arbitrary derivative security in terms of call options prices this valuation formula follows from the observation that a continuous derivative security can be replicated by a portfolio including a bond and call options with all possible exercise prices discrete terms are added to the original breeden litzenberger formula to reflect possible discontinuities of the call option price s derivative with respect to the exercise price these discontinuities are subsequently shown to correspond to mass points of the probability distribution of the stock price several applications of the breeden litzenberger valuation formula are demonstrated

are consumers forward looking evidence from fiscal experiments how changes in current and future income affect consumer spending is a perennial question in macroeconomics and public finance theoretical constructs such as the permanent income hypothesis are of limited assistance in resolving this issue because they neglect borrowing constraints and other market imperfections that can significantly affect the marginal propensity to spend out of current income recent empirical work has also proven inconclusive since whether consumption responds to income fluctuations by more or less than the permanent income hypothesis predicts turns critically upon whether disposable income follows a random walk or is stationary around a longrun trend see john campbell and angus deaton 1987 this controversy is unlikely to be resolved conclusively because it is notoriously difficult to distinguish a stationary but highly persistent time series from one that is nonstationary these difficulties suggest the importance of searching for natural experiments income shocks with predictable and well understood effects on future income to test models of consumer behavior changes in federal tax and transfer policy during the last two decades provide several episodes of this type analyzing the effects of these tax changes is also central to understanding the role of fiscal policy in affecting national saving this paper examines two aspects of consumer response to tax changes section i argues that consumption responds to temporary income tax shocks by more than the permanent income hypothesis would suggest results from the 1975 tax rebate in particular suggest that a 1 increase in transitory income raises spending by about 20 cents section ii examines consumption responses to tax announcements although the results are not conclusive they suggest that some consumers do not adjust consumption in anticipation of tax changes the final section sketches some implications for analyzing fiscal policy

a more complete conceptual framework for sme finance abstract we propose a more complete conceptual framework for analysis of sme credit availability issues in this framework lending technologies are the key conduit through which government policies and national financial structures affect credit availability we emphasize a causal chain from policy to financial structures which affect the feasibility and profitability of different lending technologies these technologies in turn have important effects on sme credit availability financial structures include the presence of different financial institution types and the conditions under which they operate lending technologies include several transactions technologies plus relationship lending we argue that the framework implicit in most of the literature is oversimplified neglects key elements of the chain and often yields misleading conclusions a common oversimplification is the treatment of transactions technologies as a homogeneous group unsuitable for serving informationally opaque smes and a frequent misleading conclusion is that large institutions are disadvantaged in lending to opaque smes

reinsurance and corporate taxation in the united kingdom life insurance industry there are two main tax related arguments regarding the use of reinsurance the income volatility reduction and the income level enhancement arguments the income volatility reduction argument contends that firms facing convex tax schedules have incentives to hedge in order to reduce the volatility of their annual taxable income and thereby lower expected tax liabilities smith c w stulz r m 1985 optimal hedging policies journal of financial and quantitative analysis 19 127 140 the income level enhancement argument advanced by adiel adiel r 1996 reinsurance and the management of regulatory ratios and taxes in the property casualty insurance industry journal of accounting and economics 22 207 240 is more specific to hedging via reinsurance this perspective holds that reinsurance enhances current reported earnings via the receipt of reinsurance commissions and so increases tax liabilities consequently insurance firms with high marginal tax rates should use less reinsurance than those with low marginal tax rates if tax matters prior studies using data on financial derivatives have produced mixed results on the validity of the first argument while adiel 1996 finds the second argument insignificant in his study of the use of reinsurance by a sample of united states us property liability insurance firms this study tests the two tax related arguments using 1992 2001 data for a sample of united kingdom uk life insurance firms we find that uk life insurers with low before planning marginal tax rates tend to use more reinsurance in contrast tax convexity is found to have no significant impact on the purchase of reinsurance and so the volatility reduction argument is not supported

financial sector debt bias abstract most tax systems create a tax bias toward debt finance such debt bias increases firm leverage and may negatively affect financial stability this paper presents novel evidence on debt bias in the non traditional financial sector i e investment banks and non bank financial intermediaries such as finance and insurance companies it also shows how debt bias in the financial sector has been affected by the global financial crisis the paper finds debt bias to be pervasive explaining as much as 10 percentage points of bank leverage these effects are more pronounced before than after the global financial crisis explained by the post crisis focus on rebuilding buffers going forward as buffers have largely been rebuilt debt bias is once again gaining prominence as a key driver of leverage decisions of financial firms underscoring the importance of policy reform at this juncture

option pricing when the variance is changing the monte carlo method is used to solve for the price of a call when the variance is changing stochastically

capital tax reform corporate finance and economic growth and welfare abstract recent empirical studies have revealed a strong impact of tax changes on corporate finance yet models of economic growth usually neglect financial structure of the representative firm in order to investigate whether the consideration of firm finance modifies the estimated outcome of capital tax reforms a corporate sector is introduced in three popular models of economic growth the paper explores analytically the impact of taxation on structures of finance and production and gives a quantitative reassessment of growth and welfare effects of tax reforms in the u s economy a general result is that standard models of exogenous and endogenous growth overestimate the growth effect and underestimate the welfare gain from tax reform

earnings management to avoid earnings decreases and losses this paper provides evidence that firms manage reported earnings to avoid earnings decreases and losses specifically in cross sectional distributions of earnings changes and earnings we lind unusually low frequencies of small decreases in earnings and small losscs and unusually high frequencies of small increases in earnings and small positive income we find evidence that two components of earnings cash flow from operations and changes in working capital are used to achieve increases in earnings we present two theories based on stakeholder use of information processing heuristics and prospect theory about the motivation for avoidance of earnings decreases and losses

proxies for the corporate marginal tax rate abstract this paper focuses on how best to measure the corporate marginal tax rate which is an important input into financial analysis of the cost of capital financing policy corporate hedging and corporate reorganizations the results indicate that the simulated tax rate used by shevlin 1990 and graham 1996 although difficult to calculate is the best available proxy for the true marginal tax rate if the simulated rate is unavailable an easy to calculate trichotomous variable or the statutory marginal tax rate which captures the progressivity in the tax schedule are reasonable alternatives better than most commonly used tax variables

tax planning regulatory capital planning and financial reporting strategy for commercial banks we test whether banks investment and financing policies can be explained by tax status we document changes in bank holdings of municipal bonds in response to changes in tax rules relating to deductibility of interest expense we also document an association between banks marginal tax rates and their investment and financing decisions which is consistent with the existence of tax clienteles however banks do not sort themselves perfectly into investment and financing clienteles because of adjustment costs we posit specific types of transaction cost impediments to tax planning and document that banks apparently trade off these costs against tax planning benefits article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

corporate tax aggression and debt we provide a tradeoff model of the capital structure that allows leverage to be a function of a firm s choice of tax aggressiveness the model s testable implications are supported empirically debt use is inversely related to corporate tax aggression for most firms and the relation is economically important this substitution effect is especially evident for firms exhibiting high tax shelter prediction scores the effect attenuates for benign forms of tax avoidance and during the recent credit crisis period for the most profitable firms debt and tax aggression are complements our results extend the empirical findings of graham and tucker 2006

as certain as debt and taxes estimating the tax sensitivity of leverage from state tax changes abstract using staggered corporate income tax changes across u s states we show that taxes have a first order effect on capital structure firms increase leverage by around 40 basis points for every percentage point tax increase consistent with dynamic tradeoff theory the effect is asymmetric leverage does not respond to tax cuts this is true even within firm tax increases that are later reversed nonetheless lead to permanent leverage increases the treatment effects are heterogeneous and confirm the tax channel tax sensitivity is greater among profitable and investment grade firms which respectively have a greater marginal tax benefit and lower marginal cost of issuing debt

new or used investment with credit constraints abstract used capital is cheap up front but requires higher maintenance payments later on we argue that the timing of these investment cash outflows makes used capital attractive to financially constrained firms since it is cheap when evaluated using their discount factor in contrast it may be expensive from the vantage point of an unconstrained agent we provide an overlapping generations model and determine the price of used capital in equilibrium agents with less internal funds are more credit constrained invest in used capital and start smaller firms empirically we find that the fraction of investment in used capital is substantially higher for small firms and varies significantly with measures of financial constraints

population matters in ecological economics abstract it is an axiom of ecological economics that resource depletion and environmental pollution depend on the number of people and how many goods and services each consumes modified by the technological efficiency of production the paper reviews some studies quantifying the contribution of human numbers to environmental impact it warns against playing this factor off against that of high consumption in rich countries it asks whether from the environmental point of view complacency about either present or predicted population size is warranted the answer depends both on fertility and mortality assumptions and on constraints such as resource and food availability the concept of cultural carrying capacity would aid societies in determining their optimal population when account is taken not only of subsistence but of quality of life a population control toolkit for both rich and poor societies is sketched and some controversial coercive policy possibilities analysed

does the source of capital affect capital structure prior work on leverage implicitly assumes capital availability depends solely on firm characteristics however market frictions that make capital structure relevant may also be associated with a firm s source of capital examining this intuition we find firms that have access to the public bond markets as measured by having a debt rating have significantly more leverage although firms with a rating are fundamentally different these differences do not explain our findings even after controlling for firm characteristics that determine observed capital structure and instrumenting for the possible endogeneity of having a rating firms with access have 35 more debt copyright 2006 oxford university press

can r d expenditure avoid corporate bankruptcy comparison between japanese machinery and electric equipment industries using dea discriminant analysis abstract this study compares data envelopment analysis discriminant analysis dea da with altman s financial ratio analysis to identify the position of dea da in financial performance analysis then this study applies dea da to examine whether research and development r d expenditure influences the financial performance of japanese machinery industry and electric equipment industry the investigation of dea da identifies that the r d expenditure makes a positive impact on the financial performance of japanese machinery industry but it yields a negative impact on japanese electric equipment industry the result implies that the influence of r d expenditure on financial performance including the avoidance of bankruptcy depends upon the type of a manufacturing industry a rationale regarding why such a discrepancy has occurred between the two japanese manufacturing industries is because the life cycle of electric equipments is shorter than that of the machinery products furthermore the electric equipment industry faces more fierce competition than the machinery industry this study suggests that the japanese electric equipment industry needs r d expenditure for competition in its global market however it is a high risk and high return investment in contrast the japanese machinery is a technologically mature industry where the r d expenditure influences positively its financial performance in this sense the r d expenditure is a low risk and necessary investment

taxes and corporate policies evidence from a quasi natural experiment we document important interactions between tax incentives and corporate policies using a quasi natural experiment provided by a surprise announcement that imposed corporate taxes on a group of canadian publicly traded firms the announcement caused a dramatic decrease in value prospective tax shields partially offset the losses adding 4 6 to firm value on average and vary with the tax status of the marginal investor further firms adjust leverage payout cash holdings and investment in response to changing tax incentives overall the event study and time series evidence supports the view that taxes are important for corporate decision making

the priority structure of corporate liabilities most discussions of corporate capital structure effectively assume that all debt is the same yet debt differs by maturity covenant restrictions conversion rights call provisions and priority here we examine priority structure across a sample of 4995 compustat industrial firms from 1981 to 1991 we analyze the variation in the use of capital leases secured debt ordinary debt subordinated debt and preferred stock both as a fraction of the firm s market value and as a fraction of total fixed claims our evidence provides consistent support for contracting cost hypotheses mixed support for tax hypotheses and little support for the signaling hypothesis

hedging derivative securities and incomplete markets an e arbitrage approach given a european derivative security with an arbitrary payoff function and a corresponding set of underlying securities on which the derivative security is based we solve the optimal replication problem find a self financing dynamic portfolio strategy involving only the underlying securities that most closely approximates the payoff function at maturity by applying stochastic dynamic programming to the minimization of a mean squared error loss function under markov state dynamics we derive recursive expressions for the optimal replication strategy that are readily implemented in practice the approximation error or e of the optimal replication strategy is also given recursively and may be used to quantify the degree of market incompleteness to investigate the practical significance of these e arbitrage strategies we consider several numerical examples including path dependent options and options on assets with stochastic volatility and jumps

debt leases taxes and the endogeneity of corporate tax status we provide evidence that corporate tax status is endogenous to financing decisions which induces a spurious relation between measures of financial policy and many commonly used tax proxies using a forward looking estimate of before financing corporate marginal tax rates we document a negative relation between operating leases and tax rates and a positive relation between debt levels and tax rates this is the first unambiguous evidence supporting the hypothesis that low tax rate firms lease more and have lower debt levels than high tax rate firms many theories of capital structure imply that all else equal the incentive to use debt financing increases with a firm s marginal tax rate due to the tax deductibility of interest expense e g modigliani and miller 1963 deangelo and masulis 1980 conversely leasing models generally predict that firms with low marginal tax rates employ relatively more leases than do firms with high marginal tax rates the logic behind the leasinlg prediction is that leases allow for the transfer of tax shields from firms that cannot fully utilize the associated tax deduction lessees to firms that can lessors e g myers dill and bautista 1976 smith and wakeman 1985 ross westerfield and jaffe 1996 despite these straightforward predictions empirically testing for tax effects is difficult because a spurious relation exists between the financing decision and many commonly used tax proxies specifically both interest expense and lease payments are tax deductible thus a firm that finances its operations with debt or leases reduces its taxable income potentially lowering its expected marginal tax rate if not properly addressed this endogeneity of the tax rate can bias an experiment in favor of finding a negative

capital structure choice and company taxation a meta study this paper provides a quantitative review of the empirical literature on the tax impact on corporate debt financing synthesizing the evidence from 46 previous studies we find that this impact is substantial in particular the tax rate proxy determines the outcome of primary analyses measures like the simulated marginal tax rate graham 1996a avoid a downward bias in estimates for the debt response to tax moreover debt characteristics econometric specifications and the set of control variables affect tax effects accounting for misspecification biases by means of meta regressions we predict a marginal tax effect on the debt ratio of 0 3

methodological comparison between dea data envelopment analysis and dea da discriminant analysis from the perspective of bankruptcy assessment abstract this study compares dea data envelopment analysis with dea da discriminant analysis in terms of bankruptcy assessment recently many dea researchers propose a use of dea as a quick and easy tool to assess corporate bankruptcy meanwhile other dea researchers discuss a use of dea da for bankruptcy based financial analysis the two groups are very different from the conventional use of dea because we have long applied dea to the measurement of operational performance or productivity analysis the two research groups open up a new application area bankruptcy based financial assessment for dea this study discusses methodological strengths and weaknesses of dea and dea da from the perspective of corporate failure the proposed comparative analysis has the three main criteria a how to handle negative data in financial variables b how to handle data imbalance between default and non default firms and c how to identify a failure process over time this study finds that dea is a managerial tool for the initial assessment of corporate failure and dea is useful for busy corporate leaders and financial managers in contrast dea da is useful for researchers and individuals who are interested in the detailed assessment of bankruptcy and its failure process in a time horizon

labor unions and tax aggressiveness abstract we examine the impact of unionization on firms tax aggressiveness we find a negative association between firms tax aggressiveness and union power and a decrease in tax aggressiveness after labor union election wins this relation is consistent with labor unions influencing managers in one or both of two ways 1 constraining managers ability to invest in tax aggressiveness through increased monitoring or 2 decreasing returns to tax aggressiveness that arise from unions rent seeking behavior we also find preliminary evidence that the market expects these reductions around union elections and discounts firms that likely add shareholder value via aggressive tax strategies

debt and the marginal tax rate abstract do taxes affect corporate debt policy this paper tests whether the incremental use of debt is positively related to simulated firm specific marginal tax rates that account for net operating losses investment tax credits and the alternative minimum tax the simulated marginal tax rates exhibit substantial variation due to the dynamics of the tax code tax regime shifts business cycle effects and the progressive nature of the statutory tax schedule using annual data from more than 10 000 firms for the years 1980 1992 i provide evidence which indicates that high tax rate firms issue more debt than their low tax rate counterparts

capital over the business cycle renting versus ownership we find that capital renting makes up one fifth of u s capital expenditures and it increases during downturns further we present cross country evidence that output losses after financial crises are smaller where renting is more prevalent to understand these findings we build a general equilibrium model with borrowing constraints and with the option to rent or buy capital the countercyclicality of rentals occurs because their supply increases as renting serves as an additional means of savings when credit markets malfunction moreover demand also shifts toward rentals as they become relatively cheaper by absorbing excess savings renting mitigates financial crises

information asymmetry valuation and the corporate spin off decision we empirically analyze the information hypothesis that the separation of a rm s divisions into independently traded units through a spin o enhances value because it mitigates information asymmetry about the rm consistent with this hypothesis we nd that rms that engage in spin o s have higher levels of information asymmetry compared to their industry and size matched counterparts and the information problems decrease signi cantly after the spin o the gains around spin o s are positively related to the degree of information asymmetry and this relation is more pronounced for rms with fewer negative synergies between divisions finally rms with higher growth opportunities and rms in need of external capital show a higher propensity to engage in spin o s they also raise more capital following a spin o which is consistent with the view that

the transition to an oil contraction economy abstract a normative analysis of the problem of optimal extraction of a nonrenewable resource is considered the economy depends on the essential nonrenewable resource and the rate of the resource extraction is increasing over time at some point the government gradually switches to a sustainable in sense of non decreasing consumption over time pattern of the resource extraction different approaches are offered for the construction of the paths of switching to decreasing resource use some seemingly attractive short run policies of switching to decreasing extraction can run counter to long run criteria if we consider the maximin principle applied to the negative shock on the output percent change as the short run criterion then the optimal transition path can be consistent with the long run government goals it is shown analytically and numerically that there are values of parameters for the transition paths of extraction that consumption along these paths is asymptotically constant or infinitely growing a new approach to the rawlsian maximin criterion which allows for growth of consumption is offered

have the tax benefits of debt been overestimated abstract we re examine the claim that many corporations are underleveraged in that they fail to take full advantage of debt tax shields we show prior results suggesting underleverage stems from biased estimates of tax benefits from interest deductions we develop improved estimates of marginal tax rates using a non parametric procedure that produces more accurate estimates of the distribution of future taxable income we show that additional debt would provide firms with much smaller tax benefits than previously thought and when expected distress costs and difficult to measure non debt tax shields are also considered it appears plausible that most firms have tax efficient capital structures

stock price reaction and value relevance of recognition versus disclosure the case of stock based compensation this study examines the equity price reaction to the pronouncements related to accounting for stock based compensation and assesses the value relevance of recognition versus disclosure in financial reporting we document that firms exhibit significant abnormal returns around the issuance of the exposure drafts proposing to require recognition of stock based compensation costs and also around the event reversing that decision to require disclosure only while encouraging recognition we also document that the abnormal returns are most pronounced for high tech high growth and start up firms our results are consistent with the contracting theory and show that disclosure is not a substitute for recognition r 2002 elsevier science b v all rights reserved

operating leases and the assessment of lease debt substitutability operating leases are estimated in the current paper to be approximately thirteen times larger than finance leases on average in recognition of this the paper investigates the degree of substitutability between leasing and non lease debt using a comprehensive measure of leasing improving on the partial measures used in prior research operating lease liabilities are estimated using the constructive capitalisation approach suggested by imhoff lipe and wright 1991 accounting horizons 5 pp 51 63 modified to incorporate company specific and uk relevant assumptions the results imply that leasing and debt are partial substitutes with 1 of leasing displacing approximately 0 23 of non lease debt on average consistent with the argument that lessors bear some risks which are not inherent in debt contracts these findings suggest that substitution effects are not uniform across lease types

human capital capital structure and employee pay an empirical analysis abstract we test the predictions of titman 1984 and berk stanton and zechner 2010 by examining the effect of leverage on labor costs leverage has a significantly positive impact on cash equity based and total compensation of chief executive officers ceos compensation of new ceos hired from outside the firm is positively related to prior year firm leverage in addition leverage has a positive and significant impact on average employee pay the incremental total labor expenses associated with an increase in leverage are large enough to offset the incremental tax benefits of debt the empirical evidence supports the theoretical prediction that labor costs limit the use of debt

taxes and capital structure evidence from firms response to the tax reform act of 1986 while the theoretical relation between taxes and capital structure has been extensively analyzed the empirical evidence on this issue has thus far been inconclusive one of the main difficulties confronting previous empirical studies of the cross sectional relationship between taxes and leverage was the control of intervening variables the tax reform act of 1986 tra which drastically changed the tax regime provides a unique opportunity to assess the interaction between taxes and leverage decisions in a controlled environment the authors test the relationship between leverage and certain tax related variables for a large sample of companies in the years surrounding the enactment of tra the results support the tax based theories of capital structure the findings indicate that there exists a substitution effect between debt and nondebt tax shields and that both corporate and personal tax rates affect leverage decisions coauthors are dan givoly aharon r ofer and oded sarig article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

analyst coverage and corporate tax aggressiveness abstract we examine the impact of analyst coverage on corporate tax aggressiveness to address endogeneity concerns we perform a difference in differences analysis using a setting which causes exogenous decreases in analyst coverage our tests identify a negative causal effect of analyst coverage on tax aggressiveness suggesting that higher analyst coverage constrains corporate tax aggressiveness further cross sectional variation tests find that this constraining effect on tax aggressiveness is more pronounced in firms with lower investor recognition and firms with more opaque information environments our results are consistent with the notion that higher analyst coverage increases the visibility of aggressive tax planning behavior as well as heightens analysts demand for more transparent information which in turn reduces tax aggressiveness

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

using tax return data to simulate corporate marginal tax rates abstract we document that simulated corporate marginal tax rates based on financial statement data shevlin t 1990 estimating corporate marginal tax rates with asymmetric tax treatment of gains and losses the journal of the american taxation association 11 51 67 graham j 1996a debt and the marginal tax rate journal of financial economics 41 41 73 are highly correlated with simulated rates based on corporate tax return data we provide algorithms that can be used to estimate the book or tax simulated rates when they are not available we find that the simulated book marginal tax rate does a better job of explaining financial statement debt ratios than does the analogous tax return variable and discuss how the book simulated rate is likely to be an appropriate measure in settings with global long term considerations

public pressure and corporate tax behavior we use a shock to the public scrutiny of firm subsidiary locations to investigate whether that scrutiny leads to changes in firms disclosure and corporate tax avoidance behavior actionaid international a nonprofit activist group levied public pressure on noncompliant u k firms in the ftse 100 to comply with a rule requiring u k firms to disclose the location of all of their subsidiaries we use this setting to examine whether the public pressure led scrutinized firms to increase their subsidiary disclosure decrease tax avoidance and reduce the use of subsidiaries in tax haven countries compared to other firms in the ftse 100 not affected by the public pressure the evidence suggests that the public scrutiny sufficiently changed the costs and benefits of tax avoidance such that tax expense increased for scrutinized firms the results suggest that public pressure from outside activist groups can exert a significant influence on the behavior of large publicly traded firms our findings extend prior research that has had little success documenting an empirical relation between public scrutiny of tax avoidance and firm behavior

do firms undertake self tender offers to optimize capital structure this study investigates capital structure around 286 self tender offers from 1980 to 1997 firms that undertake self tender offers generally have debt ratios below their predicted levels before the offers the debt ratios following nondefensive self tender offers are close to predicted levels while the ratios following defensive self tender offers are above predicted levels further 20 and 43 of the debt ratings are downgraded following nondefensive and defensive self tender offers respectively finally the increases in debt ratios around the offers are negatively related to the difference from the predicted debt ratio before the offers

financial distress outside directors and corporate tax aggressiveness spanning the global financial crisis an empirical analysis abstract we examine financial distress and tax aggressiveness spanning the global financial crisis gfc of 2008 and the impact of the interaction between board independence and firm specific financial distress on tax aggressiveness our regression results show that both financial distress and the gfc are positively associated with tax aggressiveness more importantly we find that the positive association between financial distress and tax aggressiveness is magnified by the gfc we also observe that the interaction between board independence and financial distress is positively associated with tax aggressiveness our results are robust to multiple measures of financial distress and tax aggressiveness

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

information time option pricing theory and empirical evidence abstract with a stochastic time change from calendar time to information time we derive a parsimonious option pricing formula with stochastic volatility as a risk neutral poisson sum of merton s 1973 prices over the option s information time maturity domain the formula contains two unobservable parameters information arrival intensity and information time asset volatility with stochastic volatility induced by random information arrival when the information arrival rate intensifies the option price increases and vice versa we test the formula in pricing hedging and excess profits capture empirically using currency and the s p 500 futures options transaction data

tax avoidance cost of debt and shareholder activism evidence from korea abstract this paper examines the impact of tax avoidance on the cost of debt and its interaction effect with shareholder activism using korean firms i find a negative relationship between tax avoidance and the cost of debt supporting the trade off theory further tests reveal that the negative relationship becomes stronger when the level of institutional ownership is high it becomes even stronger after 1998 when the shareholder rights of institutional investors were strengthened it suggests that the managerial opportunism theory has an additional explanation for tax avoidance activities my findings indicate that tax avoidance reduces the cost of debt through trade offs and creates a managerial rent diversion which is mitigated in firms with larger institutional holdings

competition and bias we attempt to measure the effect of competition on bias in the context of analyst earnings forecasts which are known to be excessively optimistic because of conflicts of interest our natural experiment for competition is mergers of brokerage houses which result in the firing of analysts because of redundancy e g one of the two oil stock analysts is let go and other reasons such as culture clash we use this decrease in analyst coverage for stocks covered by both merging houses before the merger the treatment sample to measure the causal effect of competition on bias we find that the treatment sample simultaneously experiences a decrease in analyst coverage and an increase in optimism bias the year after the merger relative to a control group of stocks consistent with competition reducing bias the implied economic effect from our natural experiment is significantly larger than estimates from ols regressions that do not correct for the endogeneity of coverage this effect is much more significant for stocks with little initial analyst coverage or competition

an approach to statistical inference in cross sectional models with security abnormal returns as dependent variable several recent event studies test hypotheses about the association between event related abnormal security returns and firm characteristics using a three step procedure first forecast model parameters are estimated usually parameters of a market model second prediction errors or residuals are computed over an event period third prediction errors are regressed cross sectionally on firm characteristics hypothesized to influence the impact of the event on share values results of these regressions are used to draw inferences about the relation between abnormal returns and firm characteristics researchers who employ three step procedures acknowledge that crosssectional ols regressions lead to valid inferences if the disturbances are iid normal in cross section see for example leftwich 1981 p 23 and lustgarten 1982 p 138 while sufficient assumptions to draw valid inferences from ols regressions are clear these assumptions are violated if there is cross correlation and cross sectional heteroscedasticity in the firm return processes from which the prediction errors are estimated assumptions about the processes generating these prediction

option values under stochastic volatility theory and empirical estimates abstract this paper numerically solves the call option valuation problem given a fairly general continuous stochastic process for return volatility statistical estimators for volatility process parameters are derived and parameter estimates are calculated for several individual stocks and indices the resulting estimated option values do not differ dramatically from black scholes values in most cases although there is some evidence that for longer maturity index options black scholes overvalues out of the money calls in relation to in the money calls

do firms hedge in response to tax incentives there are two tax incentives for corporations to hedge to increase debt capacity and interest tax deductions and to reduce expected tax liability if the tax function is convex we test whether these incentives affect the extent of corporate hedging with derivatives using an explicit measure of tax function convexity we find no evidence that firms hedge in response to tax convexity our analysis does however indicate that firms hedge to increase debt capacity with increased tax benefits averaging 1 1 percent of firm value our results also indicate that firms hedge because of expected financial distress costs and firm size an increasing number of corporations use financial derivatives each year the international swaps and derivatives association reports that the notional value of outstanding otc swap contracts increased from 11 3 trillion in 1994 to more than 60 trillion by mid 2000 http 00www isda org this is interesting because financial theory tells us that corporate risk management enhances value only in the presence of costly market imperfections a number of empirical studies examine derivative holdings to identify which of the proposed theoretical incentives and imperfections lead to corporate hedging our paper adds to the hedging literature by testing whether corporations respond to two tax related incentives to hedge the incentive to reduce volatility thereby increasing debt capacity and the tax benefits of debt and the incentive to reduce expected tax liabilities by reducing the volatility of taxable income we also use a refined dependent variable to measure net

option arbitrage and strategy with large price changes abstract arbitrage pricing theorems are derived for options on stocks with jumps as a well as local movements the resulting valuation formulas depend on observable variables only closed form valuation expressions are obtained in the case of large positive and negative jumps these results translate into a simple algebra for characterizing the risk of arbitrage and investment portfolios a continuous time formulation of the infinite variance hypothesis leads to isomorphic pricing expressions

capital market imperfections and the incentive to lease abstract this paper evaluates the influence of financial contracting costs on public corporations incentives to lease fixed capital we argue that firms facing high costs of external funds can economize on the cost of funding by leasing we construct several measures of leasing propensity plus some a priori indicators of the severity of financial constraints facing firms we find that the share of total annual fixed capital costs attributable to either capital or operating leases is substantially higher at lower rated non dividend paying cash poor firms those likely to face relatively high premiums for external funds

collateral and the choice between bank debt and public debt this paper tests how collateral value affects a firm s choice between bank debt and public debt by considering the exogenous variation in the market value of a firm s real estate assets caused by fluctuations in local real estate prices using local land supply elasticities as an instrument for local real estate prices i estimate that a one standard deviation increase in collateral value causes bank debt as a fraction of total debt to increase by six percentage points this paper was accepted by wei jiang finance

economic consequences of increasing the conformity in accounting for uncertain tax benefits abstract commentary during the development of fasb interpretation no 48 suggests the interpretation could be costly for firms because new disclosure requirements could be used by the irs to more effectively challenge uncertain tax positions stock returns around fin 48 pronouncements suggest investors were not concerned about an increase in tax costs and investors responded favorably to initial disclosures required under fin 48 however we document a significant negative market reaction to subsequent news of a senate inquiry into these disclosures consistent with investors revising their beliefs over the potential for additional tax costs

general properties of option prices when the underlying price process is a one dimensional diffusion as well as in certain restricted stochastic volatility settings a contingent claim s delta is bounded by the infimum and supremum of its delta at maturity further if the claim s payoff is convex concave the claim s price is a convex concave function of the underlying asset s value however when volatility is less specialized or when the underlying process is discontinuous or non markovian a call s price can be a decreasing concave function of the underlying price over some range increasing with the passage of time and decreasing in the level of interest rates much of the financial options literature derives precise option prices when the underlying asset price process is completely specified since it is empirically difficult to ascertain what the true underlying process is another part of that literature is concerned with deriving general properties of option prices when the underlying price process is not fully specified but instead is assumed to belong to some general class of stochastic processes merton 1973 cox and ross 1976 jagannathan 1984 in particular in the absence of arbitrage opportunities and assuming that the risk neutralized stock price follows a proportional stochastic process a risk neutral return distribution independent of price merton 1973 and jagannathan 1984 show that a call option s price is an increasing convex function of the stock price cox and ross 1976

labor unemployment risk and corporate financing decisions this paper examines the impact of labor unemployment risk on corporate financing decisions theory suggests that firms choose conservative financial policies partly as a means of mitigating worker exposure to unemployment risk using changes in state unemployment insurance benefit laws as a source of variation in the costs borne by workers during layoff spells we explore the connection between unemployment risk and the corporate financing decisions of public firms in the united states we find that increases in legally mandated unemployment benefits lead to increases in corporate leverage the impact of reduced unemployment risk on financial policy is especially strong for firms that have greater layoff separation rates labor intensity and financing constraints the estimated premium required to compensate workers for unemployment risk due to financial distress is about 57 basis points of firm value for a bbb rated firm these findings suggest that labor market frictions have a significant impact on corporate financing decisions

on the consistency of the black scholes model with a general equilibrium framework we construct a simple economy with consumption only at the final date in which we endogenize the stochastic behavior of prices assumed in the black scholes model certain preferences constant proportional risk aversion and beliefs are shown to be sufficient and necessary in certain respects for the existence of such an equilibrium the analysis is then generalized to a continuous consumption framework in which we embed the merton proportional dividend model

pricing stock and bond options when the default free rate is stochastic we derive formulas for the valuation of call options on stocks and bonds when the defaultfree rate is stochastic the formulas highlight the role of the correlation between the unanticipated returns on the underlying security and the changes in the short term rate in determining the options value our numerical analysis indicates that option prices predicted by the proposed formula differ from those predicted by the black and scholes formula when this correlation is relatively large and the short term rate s instantaneous variance is relatively large as well moreover the proposed formula predicts higher lower stock option prices than those predicted by the black and scholes formula for correlation values that are lower higher than some positive critical value

does executive portfolio structure affect risk management ceo risk taking incentives and corporate derivatives usage abstract this paper extends the investigation of the effect of managerial motives on hedging policy i utilize a proxy variable that incorporates ceo incentives to increase risk relative to incentives to increase stock price the variable is directly measured using observed characteristics of ceo portfolios of stock and option holdings furthermore ceo risk taking incentives are modeled as a choice variable to eliminate the simultaneity bias of modeling risk taking incentives as an exogenous variable if modeled as a simultaneous system of equations a strong negative link between ceo risk taking incentives and the amount of derivative holdings exists this result is consistent with the notion that derivatives are used for hedging purposes both the characteristics of stock and option holdings are important in determining cross sectional differences in corporate derivative holdings

holdups and overinvestment in capital markets abstract this paper considers a decentralized capital market characterized by trading frictions in which firms and suppliers need to make investment decisions before meeting with each other and bargaining over the price of capital the resulting holdup problem provides firms with a strategic incentive to overaccumulate capital so as to reduce their marginal productivity and thus the bargained price in equilibrium this strategic incentive can outweigh the usual distortionary effects of holdup problems that on their own would lead to underinvestment thus resulting in the economy to overinvest in a setting with both capital and labor the holdup problem in capital markets interacts with holdup problems in labor markets this presents firms with a trade off that has non trivial equilibrium effects and that depending on the substitutability of capital and labor and the firm s bargaining power in each market can mitigate or exacerbate the overinvestment result

the term structure of lease rates with endogenous default triggers and tenant capital structure theory and evidence this paper focuses on the defaultable lease rate term structure with endogenous default we combine the competitive lease market argument proposed by grenadier 1996 and the endogenous default structural model proposed by leland and toft 1996 to examine the interaction between the lessee s capital structure and the equilibrium lease rate under this framework determining the lease rate is a simultaneous equation problem that captures the tradeofi between debt and lease flnancing using data on 2 482 real estate lease transactions we empirically conflrm the predictions derived from the numerical analysis of the model

credit risk in the leasing industry abstract this paper is devoted to the credit risk modeling issues of retail lease portfolios using a re sampling method i estimate the probability density function of losses and var measures in a portfolio of 46 732 leases issued between 1990 and 2000 by a major european financial institution my results show that physical collaterals play a major role in reducing the credit risk associated with lease portfolios however because of insufficient recognition of such collaterals under the new regulatory capital framework basel ii significant differences are observed between the estimated capital requirements and those calculated in accordance with the various basel ii approaches

option pricing with stochastic volatility information time vs calendar time empirical evidence has shown that subordinated processes represent well the price changes of stocks and futures using either transaction counts or trading volume as a proxy for information arrival it supports the contention that volatility is stochastic in calendar time because of random information arrival and thus becomes stationary in information time this contention has also been supported later in theoretical models in this paper we investigate the implication of this contention to option pricing first we price the option in calendar time where the return of the underlying asset follows a jump subordinated process we extend rubinstein s rubinstein m 1976 the valuation of uncertain income streams and the valuation of options bell j econom management sci 7 407 425 and ross s ross s 1989a information and volatility the no arbitrage martingale approach to timing and resolution irrelevancy finance44 1 17 martingale valuation methodology to incorporate the pricing of volatility risk the resulting equilibrium formula requires estimating seven parameters upon implementation we then make a stochastic time change from calendar time to information time in order to obtain a stationary underlying asset return process to price the option we find that the isomorphic option has random maturity because the number of information arrivals prior to the option s calendar time expiration date is random we value the option using dynkin s dynkin e b 1965 markov processes vols i and ii springer verlag berlin and new york version of the feynman kac formula that allows for a random terminal date the resulting information time formula requires estimating only one additional parameter compared to the black scholes s in practical application in this regard the time change has reduced the computational complexity of the option pricing problem simulations show that the formula may outperform the black scholes black f m scholes 1973 the pricing of options and corporate liabilities political econom 81 637 659 and merton merton robert c 1976a option pricing when underlying stock returns are discontinuous financial econom 3 125 143 models in pricing currency options as a first attempt to derive valuation relationships in the information time economy this investigation may suggest that the information time approach is a functional alternative to the current calendar time norm it is especially suitable for deriving volatility free portfolio insurance strategies

the leasing puzzle prevailing theories in finance and economics suggest that leases and debt are substitutes an increase in one should led to a compensating decrease in the other in particular there are three views on the magnitude of the substitution coefficient standard finance theory treats cash flows from lease obligations as equivalent to debt cash flows thus describing the tradeoff between debt and leases as one to one others are willing to use a tradeoff of leases for debt which is less than but close to one the rationale for a dollar of leases using less of debt capacity than a dollar of debt obligation is based upon the differences in the terms and nature of lease and debt contracts finally there are some who argue that since leased assets may be firm specific the risk of moral hazard may be great resulting in a tradeoff of greater than one to one that is a dollar of a lease obligation uses more of debt capacity than a dollar of a debt obligation a series of empirical tests are performed in this study on samples of approximately 600 firms covering the years 1976 through 1981 with none of the three views supported by the results instead the results indicate that leases and debt are complements greater use of debt is associated with a greater use of leasing this finding reappears consistently for each year each definition of leverage ratios and each approach to analysis this complementary relationship persists even after refinements are made to the estimation technique

self selection and analyst coverage this paper examines the relation between analysts information about a stock s future prospects and their decisions to issue investment recommendations and earnings forecasts for that stock and the implications of this relation for the observed distribution of recommendations and earnings forecast errors articles in the financial press have long argued that analysts are reluctant to issue unfavorable investment information perhaps because they fear jeopardizing potential investment banking

the 1993 tax rate increase and deferred tax adjustments a test of functional fixation this paper uses a sample of 158 deferred tax adjustments resulting from the omnibus budget reconciliation act of 1993 obra to explore the magnitude and nature of analysts and investors functional fixation on reported accounting numbers the 1993 obra passed on august 10 of 1993 included a provision that raised the corporate tax rate from 34 to 35 gaap requires companies to adjust their deferred tax assets and liabilities to recognize the income effects of tax changes in the period of the tax change sfas no 109 1992 in this case the effects of the tax rate increase on deferred taxes would be included in the income tax expense component of 1993 third quarter earnings 1

is executive compensation a substitute governance mechanism to debt financing and leasing this study examines whether and how ceo equity incentives relate to financing choices i e debt and leases using manually collected ceo compensation and lease data for a sample of large uk firms we found evidence of a negative relationship between ceo equity incentives and firm leverage we also found that ceo equity incentives and leases are negatively related the results are consistent with the theory introduced in this study on the substitutability of executive compensation and firm s debt lease financing our findings represent fresh empirical evidence and renewed interpretation regarding the relationship between executive equity based incentives and firm s financing choices the substitutability theory we introduced here suggests that firms with greater use of debt and or leases will implement less equity based compensation in mitigating the agency cost of equity

operating lease decision and the impact of capitalization in a bank oriented country abstractthis article explores the reasons why firms engage in operating leases and examines the potential impact of a change in the related accounting rules we focus on the accounting advantage of off balance financing which does not affect the typical accounting based covenants especially important in bank oriented countries however we also consider other economically based arguments using manually collected operating lease data for spanish listed firms we use the constructive capitalization method to measure as if liabilities the results confirm that not only size and industry affect the decision but that firms closer to breaching their covenants are also more inclined to choose operating leases consequently it is argued that such firms will be more affected by the accounting change indeed the inclusion of liabilities in the balance sheet might tighten financial covenants in loan agreements as evidenced in the paper not surprisingly firms are strongly opposed to the accounting change

the personal tax advantages of equity abstract we value a firm that pays its cash flows to equity through share repurchases in a dynamic environment where personal taxes are paid on capital gains upon realization the cost of capital is reduced by approximately 0 8 through the use of repurchases relative to dividends we use the empirical distribution of pre tax free cash flows in fama and french 1999 to evaluate the tradeoffs between the costs of financial distress the personal tax advantages of equity and the corporate tax advantage to debt the optimal capital structure is interior with a 3 bankruptcy cost

quadratic variation based dynamic strategies the paper analyzes a family of dynamic trading strategies which do not rely on any stochastic process assumptions aside from continuity and positivity and in particular do not require predicting future volatilities derivative payoffs can still be replicated except that this occurs at the stopping time at which the realized cumulative squared volatility hits a predetermined level the application of these results to portfolio insurance is emphasized and hedging strategies studied by black and jones and by brennan and schwartz are generalized classical results on european style options arise as special cases for example the initial cost of replicating a call or a put under the new method is given by a generalized black scholes formula which yields the ordinary black scholes formula when the volatility is derterministic

horses and rabbits trade off theory and optimal capital structure this paper examines optimal capital structure choice using a dynamic capital structure model that is calibrated to reflect actual firm characteristics the model uses contingent claim methods to value interest tax shields allows for reorganization in bankruptcy and maintains a long run target debt to total capital ratio by refinancing maturing debt using this model we calculate optimal capital structures in a realistic representation of the tra ditional trade off model in contrast to previous research the calculated optimal capital structures do not imply that firms tend to use too little leverage in practice we also esti mate the costs borne by a firm whose capital structure deviates from its optimal target debt to total capital ratio the costs of moderate deviations are relatively small suggesting that a policy of adjusting leverage infrequently is likely to be reasonable for many firms

studying firm specific effects of regulation with stock market data an application to oil price regulation regulations are often introduced and reformed in response to unanticipated changes in market forces in late 1973 for example opec quadrupled the world price of oil and u s policy makers responded by imposing oil price regulation such events pose a fundamental problem of interpretation for studies that use stock prices to identify the economic effects of regulation what portion of the capital gains or losses experienced by investors in regulated firms is due to regulation and what portion is due to unanticipated economic events to answer these questions we use microeconomic theory to derive hypotheses about how the capital gains and losses created by opec pricing and u s regulatory policies are related to the underlying characteristics of petroleum firms we test the hypotheses by including a model of firm specific abnormal returns in the standard market models of common stock returns earned by investors in petroleum firms the results indicate the u s oil production and refiner access to price controlled crude oil were sources of capital gains and that u s and foreign refining were sources of capital losses

explicit and implicit tax effects of the r d tax credit this paper investigates the effects of the 1981 research and development r d tax credit first by examining the impact of the credit on the level of r d investment and second by estimating the magnitude of the implicit tax created by the credit the two effects are interrelated because an increase in the level of r d investment will increase the demand for r d inputs thus reducing the pretax rate of return from r d activity 1 i test the credit s investment effect using a time series r d spending model that includes both factors from the industrial organization literature to control for nontax effects and an r d credit usability variable to capture the incentive created by the credit previous research has produced mixed evidence on whether the credit had any positive
