estimating the tax advantage of corporate debt this paper presents estimates of the effective tax value of incremental interest deductions for corporations taking into account that they may not be able to utilize all their interest deductions fully because of either insufficient taxable income or the availability of nondebt tax shields after describing particular features of the tax code which may drive a wedge between statutory and effective tax rates for debt finance we present estimates using the treasury corporate tax model of effective tax rates for a variety of industry groupings our estimates suggest that the after tax cost of debt varies widely across industries the magnitude of the effective tax advantage to debt finance has important implications for corporate financial behavior one issue which has been examined extensively in the corporate finance literature is whether the value of the firm is affected by the firm s leverage ratio in a recent contribution deangelo and masulis 3 have shown that financing decisions can affect the value of the firm if the effective tax advantage to debt finance varies among firms or is reduced by the presence of nondebt tax shields such as investment tax credits and depreciation deductions the effective tax advantage to debt is also an important determinant of leverage related costs gordon and malkiel 5 have recently used the statutory tax rate to estimate expected bankruptcy costs induced by the corporate tax when the firm is assumed to balance the marginal tax advantage to debt with marginal expected bankruptcy costs if however the effective tax rate for interest deductions falls short of the statutory rate the magnitude of these costs may be overstated this paper presents detailed estimates of the marginal effective tax advantage to debt finance our estimates based on data in the treasury 1978 corporate master statistical file and on simulations done with the treasury corporate tax model quantify the impact of increasing interest deductions without changing other items on the corporation s income statement 1 we simulate the impact of a change in a firm s capital structure holding its investment and production decisions constant this is an appropriate procedure for estimating the marginal

women directors on corporate boards from tokenism to critical mass academic debate on the strategic importance of women corporate directors is widely recognized and still open however most corporate boards have only one woman director or a small minority of women directors therefore they can still be considered as tokens this article addresses the following question does an increased number of women corporate boards result in a build up of critical mass that substantially contributes to firm innovation the aim is to test if at least three women could constitute the desired critical mass by identifying different minorities of women directors one woman two women and at least three women tests are conducted on a sample of 317 norwegian firms the results suggest that attaining critical mass going from one or two women a few tokens to at least three women consistent minority makes it possible to enhance the level of firm innovation moreover the results show that the relationship between the critical mass of women directors and the level of firm innovation is mediated by board strategic tasks implications for both theory and practice and future research directions are discussed

empirical evidence on the relation between stock option compensation and risk taking abstract we examine whether executive stock options esos provide managers with incentives to invest in risky projects for a sample of oil and gas producers we examine whether the coefficient of variation of future cash flows from exploration activity our proxy for exploration risk increases with the sensitivity of the value of the ceo s options to stock return volatility eso risk incentives both eso risk incentives and exploration risk are treated as endogenous variables by adopting a simultaneous equations approach we find evidence that eso risk incentives has a positive relation with future exploration risk taking additional tests indicate that eso risk incentives exhibits a negative relation with oil price hedging in a system of equations where eso risk incentives and hedging are allowed to be endogenously determined overall our results are consistent with esos providing managers with incentives to mitigate risk related incentive problems

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

advertising learning and consumer choice in experience good markets an empirical examination this article empirically analyzes different effects of advertising in a nondurable experience good market a dynamic learning model of consumer behavior is presented in which i allow both informative effects of advertising and prestige or image effects of advertising this learning model is estimated using consumer level panel data tracking grocery purchases and advertising exposures over time empirical results suggest that in this market advertising s primary effect was that of informing consumers the estimates are used to quantify the value of this information to consumers and evaluate the welfare implications of an alternative advertising regulatory regime

uniqueness and indeterminacy on the dynamics of endogenous growth abstract in this paper we study the dynamics of endogenous growth both in the model of lucas and in a generalization that incorporates a labor leisure choice we characterize the regions of the parameter space that give rise to unique equilibria as well as the regions that yield a continuum of equilibria with positive growth rates we find that such multiple equilibria exist for empirically very plausible parameters in particular when the lucas model is modified to incorporate endogenous labor journal of economic literature numbers e00 e3 o40

are nonconvexities important for understanding growth everyday experience and a simple logical argument show that nonconvexities are essential for understanding growth compared to previous statements of this well known argument the presentation here places more emphasis on the distinction between two of the fundamental attributes of any economic good rivalry and excludability it also emphasizes the difference between public goods and the technological advances that are fundamental to economic growth like public goods technological advances are rionrival goods hence they are inextricably linked to nonconvexities but in contrast to public goods which are nonexcludable technological advances generate benefits that are at least partially excludable hence innovations in the technology are for the most part privately provided this means that nonconvexities are relevant for goods that trade in private markets consequently an equilibrium with price taking in all markets cannot be sustained concluding remarks describe some of the recent equilibrium growth models that do not rely on price taking and highlight some of the implications of these models this abstract was borrowed from another version of this item

information marketing and pricing in the u s antiulcer drug market introduced into the united states in 1977 tagamet was the pioneer product in the class of antiulcer drugs known as h2antagonists by promoting ulcer healing through inhibiting acid secretion tagamet was able to heal ulcers and treat pre ulcer conditions pharmacologically on an outpatient basis thereby substituting for more costly hospital admissions and surgeries in 1983 another h2 antagonist called zantac entered and by early 1987 u s zantac sales surpassed those of the pioneering tagamet today there are four h2 antagonists sold in the united states tagamet zantac pepcid and axid zantac is now the world s largest selling prescription drug having estimated worldwide sales in 1994 of about 4 billion each of the four h2 antagonists is among the top 100 in world drug sales although tagamet lost u s patent protection on may 17 1994 in this paper we examine empirically the role of information in facilitating and explaining growth of the overall antiulcer drug market as well as in shaping the changing market shares of the four patented products the dissemination of information is due largely to the use of marketing channels such as visits by manufacturers representatives to physicians called detailing advertising in medical journals and most recently by direct to consumer advertising we examine these and also explore pricing policies product differentiation and orderof entry effects

decision making under uncertainty capturing dynamic brand choice processes in turbulent consumer goods markets we construct two models of the behavior of consumers in an environment where there is uncertainty about brand attributes in our models both usage experience and advertising exposure give consumers noisy signals about brand attributes consumers use these signals to update their expectations of brand attributes in a bayesian manner the two models are 1 a dynamic model with immediate utility maximization and 2 a dynamic forward looking model in which consumers maximize the expected present value of utility over a planning horizon given this theoretical framework we derive from the bayesian learning framework how brand choice probabilities depend on past usage experience and advertising exposures we then form likelihood functions for the models and estimate them on nielsen scanner data for detergent we find that the functional forms for experience and advertising effects that we derive from the bayesian learning framework fit the data very well relative to flexible ad hoc functional forms such as exponential smoothing and also perform better at out of sample prediction another finding is that in the context of consumer learning of product attributes although the forward looking model fits the data statistically better at conventional significance levels both models produce similar parameter estimates and policy implications our estimates indicate that consumers are risk averse with respect to variation in brand attributes which discourages them from buying unfamiliar brands using the estimated behavioral models we perform various scenario evaluations to find how changes in marketing strategy affect brand choice both in the short and long run a key finding obtained from the policy experiments is that advertising intensity has only weak short run effects but a strong cumulative effect in the long run the substantive content of the paper is potentially of interest to academics in marketing economics and decision sciences as well as product managers marketing research managers and analysts interested in studying the effectiveness of marketing mix strategies our paper will be of particular interest to those interested in the long run effects of advertising note that our estimation strategy requires us to specify explicit behavioral models of consumer choice behavior derive the implied relationships among choice probabilities past purchases and marketing mix variables and then estimate the behavioral parameters of each model such an estimation strategy is referred to as structural estimation and econometric models that are based explicitly on the consumer s maximization problem and whose parameters are parameters of the consumers utility functions or of their constraints are referred to as structural models a key benefit of the structural approach is its potential usefulness for policy evaluation the parameters of structural models are invariant to policy that is they do not change due to a change in the policy in contrast the parameters of reduced form brand choice models are in general functions of marketing strategy variables e g consumer response to price may depend on pricing policy as a result the predictions of reduced form models for the outcomes of policy experiments may be unreliable because in making the prediction one must assume that the model parameters are unaffected by the policy change since the agents in our models choose among many alternative brands their choice probabilities take the form of higher order integrals we employ monte carlo methods to approximate these integrals and estimate our models using simulated maximum likelihood estimation of the dynamic forward looking model also requires that a dynamic programming problem be solved in order to form the likelihood function for this we use a new approximation method based on simulation and interpolation techniques these estimation techniques may be of interest to researchers and policy makers in many fields where dynamic choice among discrete alternatives is important such as marketing decision sciences labor and health economics and industrial organization

informative advertising with differentiated products in this paper we study the role of promotional expenditures by sellers in a model of product differentiation advertising conveys full and accurate information about the characteristics of products heterogeneous consumers who have no source of information other than advertisements seek to purchase the products that best fit their needs despite the roles played by advertising in improving the matching of products and consumers and in increasing the elasticity of demand faced by each firm we find that the market determined levels of advertising are excessive given the extent of diversity in the market we derive a promotional equilibrium based on a specific information transmission technology paying explicit attention to the structure of consumer information and its impact on firms demand curves this allows us to study the effects of changes in the advertising technology including an increased ability to target messages to specific groups of consumers on the equilibrium in the product market we find that decreased advertising costs may reduce profits by increasing the severity of price competition

evidence on the effect of bond covenants and management compensation contracts on the choice of accounting techniques the case of the depreciation switch back abstract provisions of bond indenture agreements and management compensation contracts are examined to derive testable implications concerning management s incentives to choose among alternative accounting techniques the hypotheses are subjected to empirical examination by investigating the voluntary change from accelerated to straight line depreciation for financial reporting purposes only the methodology utilized incorporates an expectations model of accounting earnings in an attempt to separate out of the effects of earnings announcements from accounting change announcements which are often concurrent the evidence from both price and non price data is not consistent with the general hypothesis that bond covenants and management compensation contracts are important determinants of the decision to change depreciation techniques five potential explanations for the results are offered

applied welfare economics with discrete choice models economists have been paying increasing attention to the study of situations in which consumers face a discrete rather than a continuous set of choices such models are potentially very important in evaluating the impact of government programs upon consumer welfare but very little has been said in general regarding the tools of applied welfare economics indiscrete choice situations this paper shows how the conventional methods of applied welfare economics can be modified to handle such cases it focuses on the computation of the excess burden of taxation and the evaluation of quality change the results are applied to stochastic utility models including the popular cases of probit and logit analysis throughout the emphasis is on providing rigorous guidelines for carrying out applied work this abstract was borrowed from another version of this item

the stability of economic integration and endogenous growth this paper examines the transitional dynamics of economic integration in the two country endogenous growth model of rivera batiz and romer 1991 and in an extension by rivera batiz and xie 1992 it is shown that in the absence of knowledge flows across countries economic integration will generically lead to a corner solution where only one country does all the r d and the other specializes in manufactures when countries are symmetric the world growth rate in this equilibrium will always be higher than in autarky when countries differ in their human capital endowment the world growth rate with trade is always greater than the autarky growth rate of the low growth country but may or may not be greater than the autarky growth rate of the high growth country this abstract was borrowed from another version of this item

limited information and advertising in the u s personal computer industry traditional discrete choice models assume buyers are aware of all products for sale in markets where products change rapidly the full information assumption is untenable i present a discrete choice model of limited consumer information where advertising influences the set of products from which consumers choose to purchase i apply the model to the u s personal computer market where top firms spend over 2 billion annually on advertising i find estimated markups of 19 over production costs where top firms advertise more than average and earn higher than average markups high markups are explained to a large extent by informational asymmetries across consumers where full information models predict markups of one fourth the magnitude i find that estimated product demand curves are biased toward being too elastic under traditional models i show how to use data on media exposure to improve estimated price elasticities in the absence of micro ad data

advertising and competition in the ethical pharmaceutical industry the case of antihypertensive drugs abstract this paper uses data on the majority of name brand antihypertensive drugs marketed in the united states during 1988 93 to test the hypothesis that advertising decreases the price elasticity of demand in the pharmaceutical industry this is the first study to directly estimate the effects of drug product promotion on the price elasticity of demand in this industry we find strong evidence of an advertising effect in particular detailing efforts the salient means for product promotion in this industry systematically lower price sensitivity given the inverse relationship between elasticity of demand and price it is likely that consumers pay higher prices as a result of the advertising that occurs in this industry our findings are thus consistent with hurwitz and caves who find evidence that advertising inhibits entry into this market but in contrast to earlier research that found no anticompetitive effect

combining micro and macro data in microeconometric models or panel samples to improve accuracy of estimation in this paper we show how to do this efficiently we show that the gains from use of marginal information can be substantial we also discuss how to test the compatibility of sample and marginal information

transitional dynamics of economic integration and endogenous growth abstract rivera batiz and romer have demonstrated some comparative dynamic analysis namely comparing pre and post economic integration balanced growth paths and have derived interesting economic results even though these results are interesting their analysis has a serious shortcoming namely the balanced growth path studied by them exhibits a knife edge property and is unstable this clearly implies that their results are not robust in this paper we propose a modified knowledge driven model based on their model then we give a comparative dynamic analysis and show different results of economic integration from theirs

determinants of the corporate decision to capitalize interest abstract until 1974 firms could choose within gaap to capitalize or expense interest costs associated with capital expenditures the predominant practice had been to treat interest as a period expense however in 1974 the securities and exchange commission imposed a moratorium on further adoption of interest capitalization by non regulated firms this study empirically examines economic factors potentially influencing firms decisions to expense or capitalize interest prior to the sec moratorium we hypothesize that the choice may be affected by 1 the existence of management compensation agreements tied to reported earnings 2 debt covenant constraints and 3 the political costs for some firms of reporting higher earnings when compared to the control group our findings are that 1 the frequency of explicit management compensation packages was not greater for the interest capitalization group 2 firms with financial ratios closer to likely debt agreement constraints on dividends interest coverage and leverage tended to elect interest capitalization and 3 other than the largest firms in the politically sensitive petroleum refining industry the larger firms were more likely to capitalize interest

board of director gender and corporate tax aggressiveness an empirical analysis this study examines the impact of board of director gender diversity on corporate tax aggressiveness based on a sample of 418 u s firms covering the 2006 2009 period 1672 firm year observations our ordinary least squares regression results show a negative and statistically significant association between female representation on the board and tax aggressiveness after controlling for endogeneity our results are consistent across several measures of tax aggressiveness and additional robustness checks

relation of dominant problems to stages of growth in technology based new ventures two studies investigating the growth patterns of new ventures are presented in the first study a stage of growth model theorized to apply specifically to technology based new ventures was develop

evidence of the impact of mandatory changes in accounting principles on corporate loan agreements abstract the theory in this paper predicts that mandatory changes in accounting princples can affect the measurement rules defined in restrictive covenants in firms lending agreements consequently those mandatory changes can have an impact on the value of a firm s equity even if the changes appear to be merely cosmetic this contracting cost theory is tested by examining of both event related and cross sectional abnormal performance of the equity of a sample of firms when the accounting princples board changes accounting princples for business combinations the theory provides at best in incomplete explanation of the observed abnormal performance

direct to consumer advertising and consumer welfare the welfare implications of direct to consumer advertising dtca have garnered considerable attention and are complicated since the consumer delegates some decision making authority to the physician who is exposed to advertising as well in this paper i develop and estimate a structural model that explains the demand side behavior in the market for prescription drugs i then use the estimated parameters of the model to compute the impact on consumer welfare that results from changes in demand for cholesterol reducing drugs due to increased expenditure in dtca the results of the policy analysis indicate increased levels of consumer welfare due to presence of dtca in comparison to the absence of dtca the results also support the argument that dtca helps bring under diagnosed patients to the physicians offices furthermore the results of the estimation support the informative role of dtca on the decision to seek care and both informative and persuasive roles of physician advertising on the choice of the drug

taxes and firm size abstract firm size has been used as a proxy for the firm s political costs and hence managers proclivity to choose income reducing accounting procedures this study provides additional evidence on this topic by examining the association between firm size and effective corporate tax rates the latter are one component of a firm s political costs the roughly fifty largest u s exchange listed firms in particular oil and gas companies and manufacturing firms have significantly higher worldwide tax rates than other firms these higher tax rates are observed primarily after the implementation of the u s 1969 tax reform act and after the opec countries raised their tax rates on u s oil producers the findings which are insensitive to alternative sources of data alternative measures of firm size and alternative measures of effective tax rates are consistent with the use in previous studies of firm size as a proxy for the firm s political costs
