refinancing profitability and capital structure abstract we revisit the well established puzzle that leverage is negatively correlated with measures of profitability in contrast we find that at times when firms are at or close to their optimal level of leverage the cross sectional correlation between profitability and leverage is positive at other times it is negative these results are consistent with dynamic trade off models in which infrequent capital structure rebalancing is optimal the time series of market leverage and profitability in the quarters prior to rebalancing events match the patterns predicted by these models our results are not driven by investment layouts market timing payout or mechanical mean reversion of leverage

market based empirical research in accounting a review interpretation and extension a decade and a half of the most concerted and ambitious research effort in accounting history is evaluated here it is the search into the relationship between publicly disclosed accounting information and the consequences of the use of this information by the major group of usersequity investors as such consequences are reflected in characteristics of common stocks traded in major exchanges this research effort known as market based accounting research mbar obtained its impetus from major developments in finance theory during the late 1950s and early 1960s these were the portfolio selection theory and its offspring the capital asset pricing model capm and the concept of informationally efficient capital markets ecm subsequent developments in information economics agency theory and optimal incentive signaling models were quickly incorporated into mbar while the impetus to this line of research came from other disciplines accounting was not only a beneficiary but also to a modest extent a benefactor mbar is relevant to the study of capital market efficiency the capm information economics and regulation this contribution distinguishes mbar from most accounting areas whose contributions to other disciplines are negligible in

bank ceo pay performance relations and the effects of deregulation the authors test the deregulation hypothesis that posits that bank ceo compensation became more sensitive to performance as bank management became less regulated they observe a significant increase in pay performance sensitivities from their 1976 81 regulation subsample to their 1982 88 deregulation subsample these increases in pay sensitivities after deregulation are observed for salary and bonus stock options and common stock holdings the authors observe increases in the pay performance relation associated with high capitalization ratio banks consistent with providing incentives for wealth creation while even larger increases in pay performance sensitivity for lower capitalization ratio banks suggest an federal deposit insurance corporation moral hazard problem copyright 1995 by university of chicago press

the debt equity choice when firms adjust their capital structures they tend to move toward a target debt ratio that is consistent with theories based on tradeoffs between the costs and benefits of debt in contrast to previous empirical work out tests explicitly account for the fact that firms may face impediments to movements toward their target ratio and that the target ratio may change over time as the firm s profitability and stock price change a separate analysis of the size of the issue and repurchase transactions suggests that the deviation between the actual and the target ratios plays a more important role in the repurchase decision than in the issuance decision

accounting conservatism and firm investment efficiency abstract we argue that conservatism improves investment efficiency in particular we predict that it resolves debt equity conflicts facilitating a firm s access to debt financing and limiting underinvestment this permits the financing of prudent investments that otherwise might not be pursued our empirical results confirm these predictions we find that more conservative firms invest more and issue more debt in settings prone to underinvestment and that these effects are more pronounced in firms characterized by greater information asymmetries we also find that conservatism is associated with reduced overinvestment even for opaque investments such as research and development

are observed capital structures determined by equity market timing contrary to baker and wurgler 2002 i find that the importance of historical average market to book ratios in leverage regressions is not due to past equity market timing al though equity transactions may be timed to equity market conditions they do not have sig nificant long lasting effects on capital structure debt transactions exhibit timing patterns that are unlikely to induce a negative relation between market to book ratios and leverage i also find that historical average market to book ratios have significant effects on current financing and investment decisions implying that they contain information about growth opportunities not captured by current market to book ratios

the impact of regulation on ceo labor markets i examine empirically whether the executive labor market helps to slot managers with higher education quality into jobs where they can obtain greater returns from their human capital skills comparing a sample of regulated gas and electric firms with manufacturing firms i find that utilities attract ceos with a lower quality education than do unregulated firms comparing a sample of airline firms pre and postderegulation airlines have ceos with a higher quality education postderegulation these results suggest that the labor market slots ceos with a lower quality of education into regulated business environments

pricing warrants an empirical study of the black scholes model and its alternatives this paper uses a sample of over 25 000 daily warrant prices to empirically investigate potential problems with the commonly used warrant pricing model proposed by black and scholes as an extension of their call option model one problem seems to be especially important the constant variance assumption of the dilution adjusted blackscholes model appears to cause biases in model prices for almost all warrants and over the entire sample period we show that more accurate price forecasts are obtained with a specific form of the constant elasticity of variance model since the derivation of the black scholes model financial economists have speculated on its usefulness for warrant valuation in their pathbreaking paper black and scholes 1973 claim that in many cases their model can be used as an approximation to give an estimate of the warrant value however black and scholes 1973 warn that

calls of warrants timing and market reaction this paper examines the timing of and reaction to calls of callable warrants three main findings emerge first unlike convertible bonds or preferred stock callable warrants are called almost as soon as possible second there is a negative price reaction of about 3 percent when a call is announced finally at the completion of a call the stock price rebounds by an average of 7 percent the total reaction from announcement through completion of the call is a positive excess return of about 4 percent since 1980 several hundred firms have issued callable warrants typically these warrants become callable only after a predetermined date and only when the price of the underlying stock exceeds a minimum price for a prespecified number of days if the company then calls warrantholders are allotted a notice period usually 30 days to decide whether to exercise their warrants or accept a nominal call price this paper is the first to study market reaction to calls of warrants and to see if firms delay calls the results indicate that warrants are called almost as soon as exercise can be forced at the announcement of a call stock prices fall about 3 percent however they rebound by about 7 percent around the last day that warrants can be exercised because this date is known in advance this result is not expected in an efficient market the investigation of calls of warrants may provide insights into calls of convertible bonds and preferred stock both calls of warrants and calls of convertibles transfer wealth to stockholders by reducing the life of the other securityholder s options so if management tries to maximize shareholder wealth management s incentive to call warrants may resemble their incentive to call convertible securities 1 however in contrast to the results pre

determinants of target capital structure the case of dual debt and equity issues abstract we examine whether market and operating performance affect corporate financing behavior because they are related to target leverage our focus on firms that issue both debt and equity enhances our ability to draw inferences consistent with dynamic trade off theories dual issuers offset the deviation from the target resulting from accumulation of earnings and losses our results also imply that high market to book firms have low target debt ratios on the other hand consistent with market timing high stock returns increase the probability of equity issuance but have no effect on target leverage

takeovers improve firm performance evidence from the banking industry the hypothesis that takeovers provide managers with the incentive to maximize firm value is tested by examining the relationship between profitability and state statutes governing takeover activity among banks the evidence indicates that firms in states with an active takeover market are more profitable when takeover activity is restricted increased use of other mechanisms that provide an incentive to maximize firm value such as concentration of equity ownership and management ownership of stock is observed however these alternative methods have a smaller effect on profitability and do not completely compensate for the absence of an active takeover market

valuing executive stock options with endogenous departure abstract executive stock options differ from exchange traded options because of vesting and portability restrictions executive departure from the firm forces early exercise reducing the value of executive options current methodology calculates the option value by multiplying the black scholes option price by the departure probability this ignores the possibility that executive departure is less likely when stock price is high and thus is correlated with the stock price we show that this correlation implies a substantial increase in option values a similar situation occurs in performance based option packages where the actual number of options granted depends on stock performance

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

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

testing the warrant pricing model abstract implied variances from traded call options are used to compute the model prices of warrants issued by the corresponding firms several examples show that the model prices do not provide accurate estimates of the actual warrant prices even after accounting for transactions costs

employee stock options as warrants abstract previous studies ignore the fact that employee stock options are warrants because these options have been an insignificant component of firms capital structures i show that this assumption is no longer correct for example for more than 36 of my sample firms employee stock options represent a more significant claim on firm value than the firm s debt and preferred stock combined moreover in contrast to the suggestions of previous research i show that employee stock options are a significant claim on firms throughout the economy including larger firms older firms and firms in old economy industries finally i show that the presumption in prior studies that employee stock options are not warrants causes a potential misunderstanding of the risk shifting interests of securityholders and biases the analysis of capital structure issues

target behavior and financing how conclusive is the evidence the notion that firms have a debt ratio target that is a primary determinant of financing behavior is influential in finance yet how definitive is the evidence we address this issue by generating samples where financing is unrelated to a firm s current debt ratio or a target we find that much of the available evidence in favor of target behavior based on leverage ratio changes can be reproduced for these samples taken together our findings suggest that a number of existing tests of target behavior have no power to reject alternatives

testing theories of capital structure and estimating the speed of adjustment this paper examines time series patterns of external financing decisions and shows that publicly traded u s firms fund a much larger proportion of their financing deficit with external equity when the cost of equity capital is low the historical values of the cost of equity capital have long lasting effects on firms capital structures through their influence on firms historical financing decisions we also introduce a new econometric technique to deal with biases in estimates of the speed of adjustment toward target leverage we find that firms adjust toward target leverage at a moderate speed with a half life of 3 7 years for book leverage even after controlling for the traditional determinants of capital structure and firm fixed effects

robustness of option like warrant valuation abstract this paper presents a methodology for arriving at the unobserved asset value and its volatility of a firm with outstanding warrants this enables us to price warrants correctly and to examine the robustness of option like warrant valuation where the dilution that occurs when warrants are exercised is ignored our analysis helps to justify the frequent simplifying option like warrant valuation furthermore we examine 50 960 daily prices for 37 american type warrants written on 16 german stocks over the period 1979 1990 the empirical results confirm our theoretical analysis there is virtually no dilution related pricing bias of the american constant variance diffusion model with the stock price as the state variable

the role of target leverage in security issues and repurchases the paper examines whether security issues and repurchases adjust the capital structure toward the target the time series patterns of debt ratios imply that only debt reductions are initiated to offset the accumulated deviation from target leverage the importance of target leverage in earlier debt equity choice studies is driven by the subsample of equity issues accompanied by debt reductions unlike debt issues and reductions equity issues and repurchases have no significant lasting effect on capital structure therefore even firms that have target debt ratios can engage in timing the equity market

total board remuneration and company performance using a hitherto neglected source of data this paper combines executive emoluments with executive options to construct a broader measure of executive pay than has been possible in earlier british studies the result of including the long term share option component of pay along with the more commonly utilized short term component of emoluments is to reveal executive pay as being significantly more sensitive to company performance than has previously been thought to be the case the paper questions the current policy stance of british institutional investors and of the greenbury committee with respect to executive share options copyright 1996 by royal economic society

risks and financing decisions in the energy sector an empirical investigation using firm level data using a sample of 102 uk energy firms over the period 1981 2009 this paper empirically examines the effects of uncertainty on firms leverage decisions the results indicate that both firms specific and macroeconomic uncertainty have negative sizeable and statistically significant impacts on the uk energy sector firms target leverage the results also indicate that the profitability of energy firms plays an important role in uncertainty leverage relationship by changing the total effect of uncertainty on leverage while more profitable firms appear to reduce their leverage by a relatively large amount in response to increased macroeconomic uncertainty they are less likely to be affected by firm specific uncertainty these results suggest that stability in macroeconomic conditions and business activity is important to the stability of the capital structure of firms in the energy sector which would in turn be conducive to stability in their investments and production

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

sraffa leontief lange the political economy of input output economics abstract the fields of political economy and input output economics are commonly unrelated due to the discrepancy between the qualitative and quantitative analysis in economic science with the aim to overcome this separation this paper relates the basic model of production of commodities by means of commodities to the paradigm of planning as the substitute for the market by sketching the logical historical development of input output economics the model of sraffa the leontief matrices and the political economy of marxist tradition represented by oskar lange are strongly associated so that the typical qualitative concepts of planning law of value and historical development of the capitalist system can be connected to the quantitative framework of matrix programming and mathematical formalization

values prices of production and market prices some more evidence from the greek economy this paper extends the empirical investigation of the relation between labour values and different price forms in the case of the greek economy subjecting the labour theory of value to empirical tests with data from various countries helps in the derivation of general conclusions regarding its empirical validity and practical usefulness our results on the closeness of values and prices as measured by their absolute deviation and correlation the shape of the wage profit curves the predictive power of labour values over market prices compared with other value bases and the comparison of fundamental marxian categories when estimated in value and price terms provide further support for the empirical strength of the labour theory of value

values prices and wage profit curves in the us economy this paper presents labor values and prices of production calculated for the postwar u s economy using a seventy one sector input output model with fixed capital as well as actual wage profit curves during the same period it is found that the cross sectional deviations of values and prices of production from market prices are quite small between 12 and 14 percent on average over time approximately 75 percent of the variation of market prices is accounted for by changes by both values and prices of production and 93 percent of the variation of prices of production is accounted for by changes in labor values wage profit curves exhibit near linearity casting some doubt on the significance of reswitching for actual economies copyright 1989 by oxford university press

equilibrium warrant pricing models and accounting for executive stock options under apb opinion no 25 compensation expense arising from executive stock options consists of the excess of the market value of the stock over the exercise price of the options on their grant dates if the exercise price equals the market value of the stock on the grant date which is typically the case no compensation expense is recognized this accounting treatment has been frequently criticized for its bias toward underestimating the cost of an option to the issuing firm and a number of alternative valuation models have been suggested in the accounting literature by and large these valuation models have been borrowed from the finance literature where they were developed to explain the pricing of warrants and traded options the purpose of this paper is to assess empirically how well two of these valuation models perform in providing estimates of the value of traded securities warrants that are similar in many respects to executive stock options 2 this evidence should help calibrate the magnitude of the errors

on measuring the deviation of prices from values it has often been found useful to measure in some way the extent to which with profit prices diverge from zero profit values but it is not satisfactory to employ a measure which varies with the choice of numeraire for this element of arbitrariness has nothing to do with the central idea of asking how much the direction of the price vector differs from that of the value vector the authors develop a measure which involves no numeraire and then illustrate its use with data from the united kingdom the irish republic and australia copyright 1998 by oxford university press

corporate performance and managerial remuneration an empirical analysis abstract economic theories of efficient compensation predict a positive relationship between executive pay and corporate performance and yet efforts to document this relationship have been largely unsuccessful in this paper we argue that previous cross sectional studies have omitted important variables which seriously bias their results using data that focus on individual executives over time we find that executive compensation is strongly positively related to corporate performance as measured by shareholder return and growth in firm sales the results are robust to the stock market performance measure utilized

corporate behavior in adjusting to capital structure and dividend targets an econometric study this study of financing decisions by u s corporations examines the issuance of long term debt issuance of short term debt maintenance of corporate liquidity issuance of new equity and payment of dividends given costs and imperfections inherent in markets a firm s financial behavior is characterized as partial adjustment to long run financial targets individual firm data are used so that speeds of adjustment are allowed to vary by company and over time the results suggest that financial decisions are interdependent and that firm size interest rate conditions and stock price levels affect speeds of adjustment this study of financing decisions by u s corporations examines the issuance of long term debt short term debt and equity the maintenance of corporate liquidity and the payment of dividends the firm s financial behavior is characterized as partial adjustment to long run financial targets and individual firm data 1966 1978 are used to estimate firm specific time varying speeds of adjustment the results suggest that financial decisions are interdependent and that firm size interest rate conditions and stock price levels affect speeds of adjustment also the estimated coefficients are more plausible than the very small taggart 28 or very large spies 26 values found in earlier studies section i of the paper introduces the general model in section ii a tractable empirical model is developed section iii presents the data to be used in the study and discusses econometric issues in section iv results and conclusions are offered

warrant pricing jump diffusion vs black scholes this paper investigates the warrant pricing abilities of dilution adjusted versions of the black scholes and jump diffusion option pricing models because of the typically long lives of warrants their pricing is hypothesized to benefit from use of the jump diffusion model which relaxes the black scholes restriction against stock price jumps empirical results indicate that while the black scholes model almost uniformly provides more efficient estimates the jump diffusion model generally provides less biased estimates of market value particularly for the valuation of out of the money warrants and warrants on stocks with a history of large and or frequent jumps the jump diffusion model may be preferred

labour time versus alternative value bases a research note this paper provides empirical support for the law of value understood as the proposition that embodied labor time is conserved in exchanges of commodities market prices are well correlated with the sum of direct and indirect labor content is it possible to produce equally good correlations by taking the sum of direct and indirect x content where x is some input other than labor time the authors repeat the analysis for electricity iron and steel and oil and show that the answer is no the high correlations in the case of labor time are therefore not a statistical artifact copyright 1997 by oxford university press

on sraffa s standard commodity the necessity of expressing the relative price of a commodity in terms of another commodity makes it impossible to distinguish that part of any change that can be ascribed to the characteristics of the commodity itself from the part of that change that is to be ascribed to the characteristics of the commodity of reference i e the numeraire ricardo 1817 was the first to point out this problem and the need to find an invariable measure of value but he was not able to solve the problem in 1960 sraffa suggested using a bundle of commodities that he called standard commodity to accomplish this function claiming that it was a standard of value invariant with respect to changes in the distribution of income but in sraffa s book there is no explicit proof of this claim this gave rise to many misunderstandings about the standard commodity and its role as invariable measure of value this paper proposes a proper definition of an invariable measure of value and then proves that the sraffa standard commodity does fulfil the requirements of this definition copyright 2004 oxford university press

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

debt and seniority an analysis of the role of hard claims in constraining management we argue that long term debt has a role in controlling management s ability to finance future investments a company with high widely held debt will find it hard to raise capital since new security holders will have low priority relative to existing creditors conversely for a company with low debt we show there is an optimal debt equity ratio and mix of senior and junior debt if management undertakes unprofitable as well as profitable investments we derive conditions under which equity and a single class of senior long term debt work as well as more complex contracts for controlling investment behavior

the deviation of production prices from labour values some methodology and empirical evidence contrary to what is expected from indirect evidence and two commodity hypothetical examples the evdie nce provided in this paper supports david ricardo s empirical proposi tion that relative prices of production are mainly determined by labo r value ratios the results obtained indicate that a 1 percent change in profit rate will cause relative prices to change up to 2 percent and as the profit rate on gross capital is approximately 5 percent o ne ends up with a 90 percent labor theory of value the empirical evidence refers to the yugoslav economy but the factors that determ ine the deviations considered turn out to be of the same order of mag nitude as in other economies copyright 1987 by oxford university press

on the present state of the capital controversy the post war capital controversy seems to have had two distinguishable stages thanks to the unambiguous phenomena of reswitching and reverse capital deepening the first stage was conclusive in discarding from pure theory the traditional versions of neoclassical theory that relied on the notion of capital as a single quantity subsequently however when the implications of those phenomena took centre stage in the controversy together with the reformulations of the theory which intended to do away with the quantity of capital several misunderstandings prevented i shall contend decisive progress in the analysis and we entered an inconclusive phase of the discussion

incorporating active adjustment into a financing based model of capital structure abstract the conventional partial adjustment model which focuses on leverage evolution has difficulty identifying deliberate capital structure adjustments as it confounds financing decisions with the mechanical autocorrelation of leverage we propose and estimate a financing based partial adjustment model that separates the effects of financing decisions on leverage evolution from mechanical evolution the speed of adjustment soa is firm specific and stochastic and active targeting of capital structure has a multiplier effect that depends on the size of financial deficit overall we find expected soa from active rebalancing 30 more than doubles what is expected from mechanical mean reversion alone 13
