women and budget deficits if women have different economic preferences than men then female economic and political empowerment is likely to change economic policy and in turn perhaps macroeconomic outcomes in this paper we narrow the focus to fiscal policy and we investigate whether female enfranchisement affects government budget deficits in a difference in differences regression for swiss cantonal panel data we find that the inclusion of women in the electorate has reduced deficits by a statistically significant amount

the effects of tax convexity on default and investment decisions the objective of this article is to examine how default and investment triggers change under different levels of tax asymmetry when firms face nonlinear tax schedules under a convex tax schedule profits are taxed at a higher rate while losses are taxed or rebated at a lower rate thus reducing the risk shared by the government this article presents a dynamic model based on the contingent claims framework to explore the impacts of tax convexity on the triggers and we find that the impacts vary significantly depending on several countervailing forces tax convexity has a nonmonotonic relationship with both the default and investment triggers because of the government s risk sharing role the default trigger is higher when tax convexity increases while the growth option exerts a counteracting effect that lowers this trigger creating an ambiguity in the investment trigger when changing the level of tax asymmetry

corporate conservatism and relative compensation this paper demonstrates that in a simple setting with managerial concern for reputation and asymmetric information on ability most managers may refrain from undertaking innovations that stochastically dominate an industry standard common components of uncertainty lead to market inferences of managerial ability based on relative performance managers who undertake the industry standard are consequently evaluated with a more accurate benchmark than those innovating discontinuities in compensation when performance is low because of firings lead managers to have differing valuations of an accurate benchmark depending on type in particular very high and very low ability managers are more likely to undertake superior innovations than those of average ability

evidence on corporate hedging policy this paper provides empirical evidence on the determinants of corporate hedging decisions the paper examines the evidence in light of currently mandated financial reporting require ments and in particular the constraints placed on anticipatory hedging data on hedging are obtained from 1992 annual reports for a sample of 3 022 firms out of the 771 firms classified as hedgers 543 firms disclose information in their annual reports on their hedging activities the remaining 228 firms report use of derivatives but no information on hedging activities based on the evidence i draw the following conclusions with respect to the models of hedging evidence is inconsistent with financial distress cost models evidence is mixed with respect to contracting cost capital market imperfections and tax based models and evidence uniformly supports the hypothesis that hedging activities exhibit economies of scale

individual risk attitudes measurement determinants and behavioral consequences this paper studies risk attitudes using a large representative survey and a complementary experiment conducted with a representative subject pool in subjects homes using a question asking people about their willingness to take risks in general we find that gender age height and parental background have an economically significant impact on willingness to take risks the experiment confirms the behavioral validity of this measure using paid lottery choices turning to other questions about risk attitudes in specific contexts we find similar results on the determinants of risk attitudes and also shed light on the deeper question of stability of risk attitudes across contexts we conduct a horse race of the ability of different measures to explain risky behaviors such as holdings stocks occupational choice and smoking the question about risk taking in general generates the best all round predictor of risky behavior

risk preferences around the world we present results from a large scale international survey on risk preferences conducted in 53 countries in all countries we find on average an attitude of risk aversion in gains and of risk seeking in losses the degree of risk aversion shows significant cross country differences moreover risk attitudes in our sample depend not only on economic conditions but also on cultural factors as measured by the hofstede dimensions individualism and uncertainty avoidance the data may also serve as an interesting starting point for further research on cultural differences in behavioral economics data as supplemental material are available at http dx doi org 10 1287 mnsc 2013 1869 this paper was accepted by peter wakker decision analysis

ceo risk preferences and hedging decisions a multiyear analysis abstract theory and previous empirical studies suggest that ceo risk preferences affect hedging we challenge this idea in a 5 year time series setting by using inside debt i e ceo pension and deferred compensation and the ceo vega and ceo delta as proxies of ceo risk preferences and document that neither risk averse i e debt like compensation nor risk seeking i e convex compensation inducing ceo compensation packages influence corporate hedging moreover we find ceos who have more previous work experience and high job tenure to be positively related to hedging

gender differences in the allocation of assets in retirement savings plans in 1995 40 percent of working men and 32 percent of working women were covered by a defined contribution dc plan a distinguishing characteristic of these plans is that workers can generally choose how their assets are invested using data from the 1992 and 1995 surveys of consumer finances scf this paper examines whether workers differ systematically by gender in the allocation of assets in dc plans previous researchers have reported that many workers tend to invest their retirement assets too conservatively and in particular that women are less likely than men to invest in risky assets such as stocks in the presence of an equity premium a lower propensity by women to invest in stocks could translate into large differences in the accumulation of financial wealth for retirement we establish that gender differences in investment decisions exist though they are more complicated than previous studies have suggested we show that these differences are not completely explained by differences in individual or household characteristics a few studies have examined gender differences in investment decisions vickie l bajtelsmit and jack l vanderhei 1997 richard p hinz et al 1997 these studies use administrative data and report that women tend to invest their retirement funds in less risky vehicles than men michael haliassos and carol c bertaut 1995 use the 1983 scf to examine why such a large fraction of households do not own any stock they report that gender does not have a significant effect on the probability of owning stock though gender differences are not the focus of their paper what these data sources lack haliassos and bertaut being the exception is a rich set of demographic and other variables on households that theory predicts should affect investment behavior this paper adds to the literature by examining gender differences in investment decisions conditioning on such variables the results highlight the importance of including marital status risk aversion measures and the portfolio of assets held outside dc plans when examining gender differences in investment decisions in these plans

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

temperance in stock market participation evidence from france we explore empirically whether earnings uncertainty and borrowing constraints deter households from the stock market consistent with the predictions of theoretical studies of portfolio choice in the presence of uninsurable earnings since recent extensions highlight the importance of the correlation between earnings and financial risks here we use a self assessed proxy from the delta tns 2002 cross sectional survey to empirically assess the impact although income risk does not affect the participation decision of households reporting a negative correlation it does lower the participation of those who report a non negative sign consistent with economic theory predictions

are women really more risk averse than men a re analysis of the literature using expanded methods while a substantial literature in economics and finance has concluded that women are more risk averse than men this conclusion merits investigation after briefly clarifying the difference between making generalizations about groups on the one hand and making valid inferences from samples on the other this essay suggests improvements to how economists communicate our research results supplementing findings of statistical significance with quantitative measures of both substantive difference cohen s d a measure in common use in non economics literatures and of substantive overlap the index of similarity newly proposed here adds important nuance to the discussion of sex differences these measures are computed from the data on men women and risk used in 35 scholarly works from economics finance and decision science the results are considerably more mixed and overlapping than would commonly be inferred from the broad claims made in the literature with standardized differences in means mostly amounting to considerably less than one standard deviation and the degree of overlap between male and female distributions generally exceeding 80 in addition studies that look at contextual influences suggest that these contribute importantly to observations of differences both between and within the sexes

marriage and other risky assets a portfolio approach we study the joint impact of gender and marital status on financial decisions first we test the hypothesis that marriage represents in a portfolio framework a sort of safe asset and that this effect is stronger for women controlling for a number of observable characteristics we show that single women have a lower propensity to invest in risky assets than married females and males second we show that the differential behavior of single women evolves over time reflecting the increasing incidence of divorce and the expansion of female labor market participation in particular towards the end of our sample period we observe a reduction in the gap between women with different family status which can be attributed to the gradual erosion of the perception of marriage as a sort of safe asset our results therefore suggest that the differential behavior of single vs married women can be explained by the evolution of gender roles in society even after controlling for differential risk attitudes our empirical investigation is based on a dataset drawn from the 1989 2006 bank of italy survey of household income and wealth

the role of farmers behavioral attitudes and heterogeneity in futures contracts usage the relationship between farmers behavioral attitudes and use of futures contracts is examined taking into account non directly observable variables and the heterogeneity of farmers the relationships are tested on a stratified data sample of 440 farmers cluster analysis and covariance structure equation models are used to validate the relationships farmers are found not to be homogenous regarding the factors influencing their use of futures heterogeneity at the segment level masked important effects at the aggregate level notably risk attitude furthermore several psychological constructs for farmers related to market orientation risk exposure market performance and entrepreneurial behavior play important roles in their use of futures contracts

impact of mood and gender on individual investors reactions to retractions and corrections of earnings forecasts whilst individual investors reactions to earnings forecasts have been widely documented the impact that retractions and or corrections have on investors decisions has received little attention

the effects of derivatives on firm risk and value using a large sample of nonfinancial firms from 47 countries we examine the effect of derivative use on firm risk and value we control for endogeneity by matching users and nonusers on the basis of their propensity to use derivatives we also use a new technique to estimate the effect of omitted variable bias on our inferences we find strong evidence that the use of financial derivatives reduces both total risk and systematic risk the effect of derivative use on firm value is positive but more sensitive to endogeneity and omitted variable concerns however using derivatives is associated with significantly higher value abnormal returns and larger profits during the economic downturn in 2001 2002 suggesting that firms are hedging downside risk

a comparison of salient rewards in experiments money and class points abstract we use laboratory decisions with different salient rewards to elicit individual values of a risk mitigation investment in a low probability environment statistically significant gender differences were found with class points however gender differences disappeared when monetary incentives were used

education choices and returns to schooling mothers and youths subjective expectations and their role by gender abstract in this paper we investigate the role of expected returns to schooling and of perceived risks of unemployment and earnings as determinants of schooling decisions moreover our data also allow us to analyze whether youths and or mothers expectations predict schooling decisions and whether this depends on the age and gender of the youth in particular we use mexican data that contain labor market expectations of mothers and youths we find that expected returns and risk perceptions are important determinants of schooling decisions the latter in particular from the perspective of the mother boys expectations predict the decision to enter college but not to enter high school while girls own expectations do not predict either of the two educational decisions mothers expectations are particularly strong predictors of their daughters decisions

risk attitudes to low probability climate change risks wtp for flood insurance abstract natural disasters may increase in frequency and severity in the future as a result of climate change which is likely to have an impact on the demand for natural disaster insurance insights about individual risk beliefs and behavioural responses to changing risks are relevant for insurers as it allows them for example to estimate the demand for new insurance products that cover weather related damage this study elicits individual risk beliefs and the demand for low probability high impact flood insurance using the contingent valuation survey method among approximately 1000 homeowners in the dutch river delta this study is of practical relevance since currently flood insurance is not available in the netherlands while insurers have been considering to provide such insurance individuals generally do not behave in accordance with the expected utility model since a significant proportion of homeowners neglect the low probability flood risk the willingness to pay wtp of those individuals who demand flood insurance is on average considerably higher than the expected value of the flood risk they face moreover the wtp for flood insurance is less than proportionally related to increased flood probabilities that were presented to respondents in the questionnaire individuals follow a process of bayesian updating of flood probabilities since perceptions of flood risk are an important determinant of the wtp while objective risks derived from geographical characteristics influence the wtp to a lesser extent communication of baseline probabilities and changes in flood probabilities using risk ladders facilitate the comprehension of risk by respondents and has a considerable effect on the level of the wtp and its sensitivity to probability changes the results indicate that the current ex post public compensation scheme of flood damage lowers demand for private insurance

the value of corporate risk management we model and estimate the value of corporate risk management we show how risk management can add value when revenues and costs are nonlinearly related to prices and estimate the model by regressing quarterly firm sales and costs on the second and higher moments of output and input prices for a sample of 34 oil refiners we find that hedging concave revenues and leaving concave costs exposed each represent between 2 and 3 of firm value we validate our approach by regressing tobin s q on the estimated value and level of risk management and find results consistent with the model

are women more risk averse we find that single women exhibit relatively more risk aversion in financial decision making than single men using u s sample data we examine household holdings of risky assets to determine whether there are gender differences in financial risk taking as wealth increases the proportion of wealth held as risky assets is estimated to increase by a smaller amount for single women than for single men gender differences in financial risk taking are also influenced by age race and number of children greater financial risk aversion may provide an explanation for women s lower levels of wealth compared with men s jel j16 d81 g11

hedging speculation and shareholder value abstract we document that gold mining firms have consistently realized economically significant cash flow gains from their derivatives transactions we conclude that these cash flows have increased shareholder value since there is no evidence of an offsetting adjustment in firms systematic risk this finding contradicts a central assumption in the risk management literature that derivatives transactions have zero net present value and highlights an important motive for firms to use derivatives that the literature has hitherto ignored although we find considerable evidence of selective hedging in our sample the cash flow gains from selective hedging appear to be small at best

using option prices to estimate realignment probabilities in the european monetary system the case of sterling mark abstract this paper describes a procedure for estimating the market s perceived probability distribution of future exchange rates from the prices of risk reversals strangles and other currency options and uses the procedure to estimate the risk neutral ex ante probability of a realignment of the pound sterling the procedure for estimating the realignment probabilities relies on the jump diffusion model of exchange rate behavior and the resulting option pricing formula by fitting this model to market option price data i retrieve the unobserved parameters of the jump diffusion process i then use these parameter estimates to estimate the ex ante probability distribution of exchange rates and thus the realignment probabilities

managerial overconfidence and corporate risk management abstract we examine whether managerial overconfidence can help explain the observed discrepancies between the theory and practice of corporate risk management we use a unique dataset of corporate derivatives positions that enables us to directly observe managerial reactions to their speculative gains and losses from market timing when they use derivatives we find that managers increase their speculative activities using derivatives following speculative cash flow gains while they do not reduce their speculative activities following speculative losses this asymmetric response is consistent with the selective self attribution associated with overconfidence our time series approach to measuring overconfidence complements cross sectional approaches currently used in the literature our results show that managerial overconfidence which has been found to influence a number of corporate decisions also affects corporate risk management decisions

hedging financing and investment decisions theory and empirical tests abstract in this paper we theoretically and empirically examine the interaction between hedging financing and investment decisions a simple equilibrium model with costly financial distress suggests that as firms become more efficient at risky investments vis a vis low risk investments they will borrow less invest more in risky assets and hedge more the model also predicts a positive relationship between hedging and leverage a result consistent with debt capacity arguments we test the model empirically using a simultaneous equations framework to investigate the determinants of firm level hedging financing and investing decisions the results strongly support the hypothesis that the hedging financing and investment decisions are jointly determined in addition we find strong support for the central hypothesis that firms more efficient investing in risky technologies more aggressively hedge and use less debt financing in order to maximize their comparative advantage

how firms should hedge substantial academic research explains why firms should hedge but little work has addressed how firms should hedge we assume that firms can experience costly states of nature and derive optimal hedging strategies using vanilla derivatives e g forwards and options and custom exotic derivative contracts for a value maximizing firm facing both hedgable price and unhedgable quantity risks customized exotic derivatives are typically better than vanilla contracts when correlations between prices and quantities are large in magnitude and when quantity risks are substantially greater than price risks finally we discuss how our model may be applied in practice copyright 2002 oxford university press

partial ordering of unpredictable mobility with welfare implications we propose a partial ordering of unpredictable mobility in the spirit of blackwell s ordering of information structures the proposed ordering ranks mobility matrices according to the degree to which elements in a given set are likely to move from one state to another independently of their origin furthermore for an important class of transition structures our proposed ordering implies ordering thus carrying significant welfare implications moreover whenever it exists our partial ordering functions as a sufficient condition for a class of renowned mobility measures and thereby generates for a subset of transition matrices unanimous ranking among mobility indices that are not generally consistent with one another

effect of derivative accounting rules on corporate risk management behavior abstract i examine the effect of the accounting standard for derivative instruments sfas no 133 on corporate risk management behavior i classify a derivative user as an effective hedger eh firm if its risk exposures decreased after the initiation of the derivatives program and as an ineffective hedger speculator is firm otherwise i find that volatility of cash flows and risk exposures related to interest rate foreign exchange rate and commodity price decrease significantly for is firms but not for eh firms suggesting that is firms engaged in more prudent risk management activities after the adoption of sfas no 133

cross hedging under multiplicative basis risk cross hedging price risk in an incomplete financial market creates basis risk we propose a new way of modeling basis risk where price risk and basis risk are combined in a multiplicative way under this specification positive prudence is a necessary and sufficient condition for underhedging in an unbiased market using the example of cross hedging jet fuel price risk with crude oil futures we show that the new specification is superior in describing the price series and that optimal cross hedges differ significantly from those derived under the traditional additive cross hedging model

self directed pensions gender risk and portfolio choices in this paper i investigate gender differences in financial risk taking from a new perspective and i show that gender plays a different role across the risk distribution to evaluate risk taking i exploit portfolio choices following a reform that entitles almost the entire swedish workforce to choose a risk profile for a part of their public pension contributions the novel finding is that portfolio risk does not differ much between the men and women who choose less risky portfolios while the men who choose risky portfolios take on significantly more risk than do the women who choose risky portfolios the findings are robust to investors choosing the default alternative chasing past returns rebalancing and different measures of risk taking

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

exchange rate hedging financial versus operational strategies exchange rate exposure is an important source of risk for multinational corporations to mitigate the impact of exchange rate fluctuations it has been claimed that multinational corporations can employ risk management strategies not only through financial derivatives but also through operational hedges for example schering plough in its 1995 annual report p 25 argues in support of exclusive use of operational hedges to date management has not deemed it cost effective to engage in a formula based program of hedging the profitability of these operations using derivative financial instruments some of the reasons for this conclusion are the company operates in a large number of foreign countries the currencies of these countries generally do not move in the same direction at the same time conversely many corporations with large worldwide networks such as ibm or coca cola make extensive use of derivative financial instruments this paper investigates both financial and operational exchange rate risk management strategies of multinational firms while several studies have examined either firms financial hedging or firms operational hedging activities no study thus far has examined financial and operational hedging simultaneously for a large cross section of firms to the extent that the decision to use financial hedging strategies is related to and affected by the operational strategies that a firm employs it is important to examine how each strategy contributes to the overall goal of mitigating risk and improving shareholder value using a sample of u s multinational nonfinancial firms during 1996 1998 we find that operational hedging is not an effective substitute for financial risk management however we find that the more geographically dispersed a firm is the more likely it is to use financial hedges the end result on firm value is that operational hedging strategies benefit shareholders only when used in combination with financial hedging strategies

managerial incentive problems a dynamic perspective the paper studies how a person s concern for a future career may influence his or her incentives to put in effort or make decisions on the job in the model the person s productive abilities are revealed over time through observations of performance there are no explicit output contingent contracts but since the wage in each period is based on expected output and expected output depends on assessed ability an implicit contract links today s performance to future wages an incentive problem arises from the person s ability and desire to influence the learning process and therefore the wage process by taking unobserved actions that affect today s performance the fundamental incongruity in preferences is between the individual s concern for human capital returns and the firm s concern for financial returns the two need be only weakly related it is shown that career motives can be beneficial as well as detrimental depending on how well the two kinds of capital returns are aligned it is well understood by now that informational externalities may place special demands on the organization of economic exchange simple price mediated markets will frequently fail in the presence of asymmetric information in that case more elaborate contractual arrangements have to be used as substitutes for the price system lately considerable effort has been devoted to the analysis of contracting under incomplete information with the objective to understand the range of economic institutions that emerge in response to the failure of the price system the analysis of moral hazard has played a prominent role in this development moral hazard problems arise when for some reason or another transacting parties cannot contract contingent on the delivery of the good for instance in buying labour services it may be that the amount of labour supplied is not directly observable precluding a simple exchange of wage for labour as a partial remedy to this problem an imperfect mutually observed signal about the supply of labour can be used as a proxy in the contract frequently output is taken as such a proxy the drawback is that output is often influenced by other factors than labour input which induce undesirable risk into the contract one is therefore faced with a tradeoff between allocating risk associated with incomplete observability and providing incentives for a proper supply of labour gaining insight into this tradeoff is important not only for understanding contracting in the small e g managerial incentive schemes but also because it is closely related to the fundamental tension between equity and efficiency in the society as a whole while our understanding of moral hazard has advanced a lot in past years it is clear that much work remains an important question that has received little attention until

can tax convexity be ignored in corporate financing decisions abstract the standard modeling practice in corporate finance has been to assume a linear tax schedule this paper extends the structural contingent claim model of corporate finance to incorporate a more realistic convex tax schedule it is shown that tax convexity raises the optimal default boundary and thus increases the likelihood of default and also reduces the optimal leverage ratio while the former effect seems insignificant in general the effect of tax convexity on the optimal leverage ratio can be quantitatively significant we conclude that tax convexity should not be ignored in corporate financing decisions and theoretical models should use a convex tax schedule instead of a linear one thus the short answer to the question in the title is no

the volatility and price sensitivities of managerial stock option portfolios and corporate hedging we use estimates of the black scholes sensitivity of managers stock option portfolios to stock return volatility and the sensitivity of managers stock and stock option portfolios to stock price to test the relationship between managers risk preferences and hedging activities we find that as the sensitivity of managers stock and stock option portfolios to stock price increases firms tend to hedge more however as the sensitivity of managers stock option portfolios to stock return volatility increases firms tend to hedge less one of the agency costs associated with the corporate form of ownership comes from the risk aversion of the firm s managers the typical corporate manager has a significant portion of his or her wealth invested in the corporation both through portfolio holdings and the value of firm specific human capital as a result managers have an incentive to reduce firm risk more than may be desirable from the perspective of an unaffiliated diversified shareholder one way to mitigate managerial risk aversion is to provide the manager with contracts that have a payoff structure that is a convex function of the firm s stock price smith and stulz 1985 guay 1999 finds that stock options are an important way in which convexity is added to managers portfolios however as recognized by carpenter 2000 and lambert larcker and verrecchia 1991 stock options create two opposing effects on managerial incentives the first effect is sensitivity to stock return volatility due to the convex payoff structure of options the value of a manager s stock option portfolio increases with the volatility of the firm s stock returns this sensitivity to stock return volatility should ceteris paribus give the manager an incentive to take more risk the second effect is sensitivity to stock price this effect comes from the direct link between the payoff of an option and

optimal incentive contracts in the presence of career concerns theory and evidence this paper studies optimal incentive contracts when workers have career concerns concerns about the effects of current performance on future compensation we show that the optimal compensation contract optimizes total incentives the combination of the implicit incentives from career concerns and the explicit incentives from the compensation contract thus the explicit incentives from the optimal compensation contract should be strongest for workers close to retirement because career concerns are weakest for these workers we find empirical support for this prediction in the relation between chief executive compensation and stock market 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

does hedging affect firm value evidence from a natural experiment we exploit an exogenous change in basis risk in the oil and gas industry to analyze the channels through which hedging affects firm value using a difference in differences framework we find that firms affected by a basis risk shock reduce investment have lower valuations sell assets and reduce debt our findings are driven by firms with ex ante high leverage overall our results provide evidence that reducing the probability of financial distress and underinvestment risk are first order channels through which hedging affects firm value received october 5 2015 editorial decision december 22 2016 by editor david denis

do personal taxes affect capital structure evidence from the 2003 tax cut abstract because the personal tax treatments of interest and dividend income likely affect the relative cost of debt and equity financing a sharp change in tax treatment could affect firms optimal leverage this paper examines the effect of the 2003 equity income tax cut on firms debt usage because this tax cut affected only individual investors we can use a difference in differences method to identify the effect of personal tax on firms leverage previous research has found that the 2003 tax cut encouraged dividend payouts and reduced the cost of equity but it provides no link to equilibrium leverage ratios we estimate that the tax cut causes the affected firms leverage to decrease by about 5 percentage points furthermore we show that the effects of the tax cut are stronger for firms with lower marginal corporate tax rates and for firms that are not financially constrained consistent with our theoretical predictions overall we find strong evidence that personal tax is an important determinant of firms optimal leverage

corporate financial hedging with proprietary information abstract if a firm has information pertinent to its own dividend stream that is not made available to its shareholders it may be in the interests of the firm and its shareholders to adopt a financial hedging policy this is in contrast with the modigliani miller theorem which implies that with informational symmetry such financial hedging is irrelevant in certain cases hedging policies are identified that are unanimously supported by shareholders

the sensitivity of ceo wealth to equity risk an analysis of the magnitude and determinants abstract to control risk related incentive problems equity holders are expected to manage both the convexity and slope of the relation between firm performance and managers wealth i find stock options but not common stockholdings significantly increase the sensitivity of ceos wealth to equity risk cross sectionally this sensitivity is positively related to firms investment opportunities this result is consistent with managers receiving incentives to invest in risky projects when the potential loss from underinvestment in valuable risk increasing projects is greatest firms stock return volatility is positively related to the convexity provided to managers suggesting convex incentive schemes influence investing and financing decisions

does culture influence asset managers views and behavior abstract this research enters new ground by presenting comparative survey evidence on asset managers views and behavior in the united states germany japan and thailand relying on hofstede s four cultural dimensions we find that cultural differences are most helpful in understanding country differences which cannot be explained by pure economic reasoning in short controlling for various determinants the dimension of more individualism predicts less herding behavior more power distance leads to older and comparatively less experienced managers in the upper hierarchy masculinity brings men into top positions and to higher volumes of assets under personal responsibility and uncertainty avoidance is related to higher safety margins against the tracking error allowed and relatively more research effort these consequences i e the culturally different importance of herding age experience gender tracking error and research effort clearly affect investment behavior although in a complex way

leveraging entrepreneurship through private investments does gender matter using project data from a random sample of phase ii research awards from the national institutes of health sbir program we estimate the relative probability that woman owned firms are able to attract private investments to fund the transition of the technology developed under the sponsorship of the sbir program to an innovation to enter the market we find that women owned firms are as much as 16 points less likely to attract private investment dollars compared to male owned firms factors excluding the size of the sbir award held constant women owned firms that received larger awards performed substantially better although the sbir program has a legislated directive to increase the participation of woman owned firms in the program our findings suggest that it might not be sufficient to overcome market perceptions about the profitability of such investments actually bringing a developed technology to market

financial markets views about the euro swiss franc floor exchange rates and option prices incorporate market participants views about the credibility and the effects of exchange rate targets i present a model to determine exchange rates under policy targets that can be used to price options the model is estimated with euro swiss franc exchange rate and options price data in the first few months of the minimum exchange rate policy the implied survival probability of the policy for a 3 month horizon was typically less than 75 over time the credibility increased and this probability reached 95 in august 2014

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

gender differences in marketing styles recent research has found that men trade stocks more frequently than women and receive a lower price as a result the behavioral finance literature attributes this greater trading activity to men s overconfidence women s lack of overconfidence and past agricultural economics research suggest the possibility that women may be better at marketing grain than men this article uses actual transactions of farmers marketing wheat and also finds that men trade more often than women women also sell two weeks later in the marketing year there is no direct effect of gender on price received but by storing longer women receive 1 4 cents bushel less than men on average in contrast to the arguments in previous research we argue that men s greater number of trades can be better explained by men enjoying trading rather than by overconfidence

firm s output under uncertainty and asymmetric taxation we consider competitive firms operating under price uncertainty when taxation is asymmetric i e profits are taxed at a higher rate than losses are compensated in the absence of risk sharing tools the larger gap in taxation may either lower or increase the firm s optimal output depending on whether the relative measure of risk aversion is less than or larger than 1 in the presence of risk sharing markets optimal output does not depend on the tax rates nor on the price distribution or the firm s attitude towards risk the firm will engage in hedging and as a result will lower its expected taxes

the impact of government incentive on the two competing supply chains under the perspective of corporation social responsibility a case study of photovoltaic industry abstract strategy corporation social responsibility csr has received a lot of attention lately and is mainly related to environmental protection in a single supply chain under the condition of the constant tax or subsidy imposed by government this paper studies a price competition model of two environmentally friendly and harmful competing supply chains consisting of one manufacturer and one retailer respectively adopting two stage stackelberg game under the condition of incomplete knowledge assume that the manufacturers don t know the retailers knowledge but they are aware of the prior probability of retailers about selling which type of product under the decentralized supply chain and the higher the prior probability is the more likely manufacturers tend to produce the environmentally friendly pv panels this paper first quantifies the impact of products on the environment studies the impact of which on competing supply chains profit and the tariffs this paper finds that only the tariffs set by government and the values of the environmental impact satisfy a three dimensional area can the firms ensure the stable competitive market results of this analysis show that government cannot impose extreme tax or subsidy on firms and the environmental impact in the centralized supply chains is higher than that in the decentralized supply chains this paper validates the results through a case of photovoltaic pv industry from the perspective of csr and the numerical results show that there are significant impacts of different governmental policy of social responsibility and environment protection on the financial revenue and the profits of the competing supply chains and their members

social mobility and the demand for redistribution the poum hypothesis this paper examines the often stated idea that the poor do not support high levels of redistribution because of the hope that they or their offspring may make it up the income ladder this prospect of upward mobility poum hypothesis is shown to be fully compatible with rational expectations and fundamentally linked to concavity in the mobility process a steady state majority could even be simultaneously poorer than average in terms of current income and richer than average in terms of expected future incomes a e rst empirical assessment suggests on the other hand that in recent u s data the poum effect is probably dominated by the demand for social insurance in the future everyone will be world famous for e fteen minutes andy warhol 1968

being in someone else s shoes the role of gender in nascent entrepreneurship several studies have shown the existence of significant differences in the rate of new business creation between men and women specifically it has been shown that women are much less likely to be involved in entrepreneurship than men worldwide it is not yet understood however if such differences are the result of personal characteristics of the individual and of her economic environment or are instead the result of universal and perhaps evolutionary phenomena our empirical analysis is conducted using representative samples of population for 37 countries and a special form of bootstrapping that allows us to equalize individuals conditions and as a result analyze the choices of men and women put in identical economic environments and socio economic circumstances

interest rate derivatives at commercial banks an empirical investigation abstract i analyze the effects of bank characteristics and macroeconomic shocks on interest rate risk management behavior of commercial banks my findings are consistent with hedging theories based on cost of financial distress and costly external financing banks with higher probability of financial distress manage their interest rate risk more aggressively both by means of on balance sheet and off balance sheet instruments as compared to the derivative users the derivative non user banks adopt conservative asset liability management policies in tighter monetary policy regimes finally i show that the derivative non user bank s lending volume declines significantly with the contraction in the money supply derivative users on the other hand remain immune to the monetary policy shocks my findings suggest that a potential benefit of derivatives usage is to minimize the effect of external shocks on a firm s operating policies

the impact of derivatives on firm risk an empirical examination of new derivative users abstract the appropriateness of financial reporting rules for derivative securities depends on corporations reasons for using the instruments empirically little is documented about how the instruments affect firms risk exposures this study examines derivatives roles in firms initiating derivatives use the results are consistent with firms using derivatives to hedge and not to increase entity risk firm risk measured several ways declines following derivatives use realized risk reductions and decisions to initiate derivatives programs vary across firms with the expected benefits from hedging the findings emphasize the importance of hedge accounting rules that incorporate the impact of derivatives and hedged items simultaneously

spousal control and intra household decision making an experimental study in the philippines i elicit causal effects of spousal observability and communication on financial choices of married individuals in the philippines when choices are private men put money into their personal accounts when choices are observable men commit money to consumption for their own benefit when required to communicate men put money into their wives account these strong treatment effects on men but not women appear related more to control than to gender men whose wives control household savings respond more strongly to the treat ment and women whose husbands control savings exhibit the same response changes in information and communication interact with underlying control to produce mutable gender specific outcomes

estimating the value of employee stock option portfolios and their sensitivities to price and volatility the costs associated with compiling data on employee stock option portfolios is a substantial obstacle in investigating the impact of stock options on managerial incentives accounting choice financing decisions and the valuation of equity we present an accurate method of estimating option portfolio value and the sensitivities of option portfolio value to stock price and stock return volatility that is easily implemented using data from only the current year s proxy statement or annual report this method can be applied to either executive stock option portfolios or to firm wide option plans in broad samples of actual and simulated ceo option portfolios we show that these proxies capture more than 99 of the variation in option portfolio value and sensitivities sensitivity analysis indicates that the degree of bias in these proxies varies with option portfolio characteristics and is most severe in samples of ceos with a large proportion of out of the money options however the proxies explanatory power remains above 95 in all subsamples

tax incentives to hedge for corporations facing tax function convexity hedging lowers expected tax liabilities thereby providing an incentive to hedge we use simulation methods to investigate convexity induced by tax code provisions on average the tax function is convex although in approximately 25 percent of cases it is concave carrybacks and carryforwards increase the range of income with incentives to hedge other tax code provisions have minor impacts among firms facing convex tax functions average tax savings from a five percent reduction in the volatility of taxable income are about 5 4 percent of expected tax liabilities in extreme cases these savings exceed 40 percent if a firm faces a convex tax function then hedging that reduces the volatility of taxable income reduces the firm s expected tax liability for a firm facing some form of tax progressivity when taxable income is low its effective marginal tax rate will be low but when income is high its tax rate will be high if such a firm hedges the tax increase in circumstances where income would have been low is smaller than the tax reduction in circumstances where income would have been high thus lowering expected taxes in examining the importance of various motives to hedge researchers have employed two general methods survey and regression analysis there are potential problems with each for example some managers might view the information requested in a survey as proprietary or might hesitate to admit that they employ derivatives to speculate rather than hedge to employ regression methods researchers must generate proxies for tax status in addition to other firm characteristics to the extent that a tax variable e g whether the firm has a net operating loss carryforward proxies for factors such as financial distress as well as tax circumstances analysts face an identification problem in interpreting the results

corporate risk management integrating liquidity hedging and operating policies we analyze the value created by a dynamic integrated risk management strategy involving liquidity management derivatives hedging and operating flexibility in the presence of several frictions we show that liquidity serves a critical and distinct role in risk management justifying high levels of cash we find that the marginal value associated with derivatives hedging is likely to be low though we explain why some empirical studies find a higher value we explore the complex interactions between operating flexibility and financial risk management finding that substitution effects are nonmonotonic and are affected by operating leverage the nature of operating flexibility and the effectiveness of the hedging instrument this paper was accepted by jerome detemple finance

choosing to cofinance analysis of project specific alliances in the movie industry we use a movie industry project by project dataset to analyze the choice of financing a project internally versus financing it through outside alliances the results indicate that project risk is positively correlated with alliance formation movie studios produce a variety of films and tend to develop their safest projects internally our findings are consistent with internal capital market explanations we find mixed evidence regarding resource pooling i e sharing the cost of large projects finally the evidence shows that projects developed internally perform similarly to projects developed through outside alliances

tempus fugit time pressure in risky decisions we study the effects of time pressure on risky decisions for pure gain prospects pure loss prospects and mixed prospects involving both gains and losses in two experiments we find that time pressure has no effect on risk attitudes for gains but increases risk aversion for losses for mixed prospects subjects become simultaneously more loss averse and more gain seeking under time pressure depending on the framing of the prospects the results suggest the importance of aspiration levels and thus the overall probability to break even under time pressure we discuss the implications of our findings for decision making situations that involve time pressure

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

is hedging successful at reducing financial risk exposure abstractthis article analyses whether firms use risk management instruments for hedging or speculative purposes first by analysing the relationship between the firm s stock returns and financial risks in 567 euronext firms we measure the firm s exposure to risk next we investigate the effect of hedging in such exposures addressing simultaneously the endogeneity of hedging decision through a treatment effect methodology we have found that firms in our sample display higher percentages of exposure when weighed against preceding studies and confirmed that hedging reduces the level of the underlying financial exposure concluding that firms use risk management instruments with hedging purposes

does option compensation increase managerial risk appetite this paper solves the dynamic investment problem of a risk averse manager compensated with a call option on the assets he controls under the manager s optimal policy the option ends up either deep in or deep out of the money as the asset value goes to zero volatility goes to infinity however the option compensation does not strictly lead to greater risk seeking sometimes the manager s optimal volatility is less with the option than it would be if he were trading his own account furthermore giving the manager more options causes him to reduce volatility managers with convex compensation schemes play an important role in financial markets this paper solves for the optimal dynamic investment policy for a risk averse manager paid with a call option on the assets he controls the paper focuses on how the option compensation impacts the manager s appetite for risk when he cannot hedge the option position on one hand the convexity of the option makes the manager shun payoffs that are likely to be near the money under the optimal policy the manager either significantly outperforms his benchmark or else incurs severe losses furthermore in examples of optimal trading strategies asset volatility goes to infinity as asset value goes to zero yet option compensation does not strictly lead to greater risk seeking as asset value grows large or if the evaluation date is far away the manager moderates asset risk for example if the manager has constant relative risk aversion crra asset volatility converges to the merton constant as asset value goes to infinity in some situations the manager actually chooses a lower asset volatility than he would if he were investing on his own because the leverage inherent in his option magnifies his exposure to the asset volatility in addition with all constant or decreasing absolute risk averse utility functions from the hyperbolic absolute risk averse hara class giving the manager more options causes him to reduce asset volatility in the crra case for example the manager targets a fixed volatility for his personal

the two sides of derivatives usage hedging and speculating with interest rate swaps existing cross sectional findings on nonfinancial firms use of derivatives that are usually interpreted as the result of hedging may alternatively be due to speculation panel data examinations can distinguish between derivatives practices that endure over time and are therefore more likely to result from hedging and those that are more transient thus more consistent with speculation our decomposition results indicate that hedging of interest rate risk is concentrated among high investment firms consistent with costly external finance simultaneously firms appear to use interest rate swaps to manage earnings and to speculate when their executive compensation contracts are more performance sensitive

enjoying the quiet life corporate governance and managerial preferences much of our understanding of corporations builds on the idea that managers when they are not closely monitored will pursue goals that are not in shareholders interests but what goals would managers pursue this paper uses variation in corporate governance generated by state adoption of antitakeover laws to empirically map out managerial preferences we use plant level data and exploit a unique feature of corporate law that allows us to deal with possible biases associated with the timing of the laws we find that when managers are insulated from takeovers worker wages especially those of white collar workers rise the destruction of old plants falls but the creation of new plants also falls finally overall productivity and profitability decline in response to these laws our results suggest that active empire building may not be the norm and that managers may instead prefer to enjoy the quiet life

dynamic corporate risk management motivations and real implications abstract we investigate the dynamics of corporate hedging programs used by us oil producers and examine the effects of hedging maturity choice on firm value we find evidence of a concave relationship between hedging maturity and the likelihood of financial distress and oil spot prices we further investigate the motivations of the early termination of outstanding hedging contracts using the essential heterogeneity approach we evaluate the causal effects of hedging maturity on firm value marginal firm value increases with short term hedging maturity the causal effects vary across oil producers with different hidden attributes

introducing convexity into optimal compensation contracts abstract we study when it is appropriate to add a convex component such as stock options to an optimal managerial compensation contract we show that convexity is introduced when managers have moderate levels of relative risk aversion and decreasing absolute risk aversion in addition we study how convexity is affected as the distribution of outcomes becomes more skewed toward low outcomes here we show that while convexity increases when skewness is increased without regard to the effect on mean stock price the opposite effect results when increases in skewness leave the mean stock price unchanged

political event portfolios abstract we use data from betting markets to analyze the sensitivity of stock returns to potential outcomes of political events such as elections by classifying stocks into expected conditional winners and losers prior to such an event we form portfolios that generate large positive returns after the event date conditional on correctly anticipating the outcome the approach is illustrated using data from the 2016 us presidential election and the 2016 brexit referendum we show that these sensitivities contain information about event related returns beyond that of firm characteristics whose predictive power has been documented in the literature

on the credibility of the euro swiss franc floor a financial market perspective we estimate the risk neutral break probabilities of a realignment of the eur chf 1 20 floor maintained by the snb from september 6 2011 to january 15 2015 using put options and an option pricing model which assumes a lower barrier for the exchange rate we estimate probabilities considerably different from zero even when the exchange rate traded far above the floor we observe a drastic increase in the break probabilities up to approximately 50 shortly before the floor was abandoned from an option market perspective the credibility of the snb in maintaining the floor was thus substantially lower than publicly claimed

measuring social mobility as unpredictability by associating mobility with the unpredictability of social states new measures of social mobility may be constructed we propose a family of three state by state and aggregate scalar predictability measures the first set of measures is based on the transition matrix the second uses a sampling approach and permits statistical testing of the hypothesis of perfect mobility providing a new justification for the use of the x2 statistic the third satisfies the demanding criterion of period consistency an empirical example demonstrates the usefulness of the new measures to complement existing ones in the literature

gender bias and credit access we extract an exogenous measure of gender bias from survey responses by descendants of u s immigrants on questions about the role of women in society we then use data on around 6 000 small business firms from 17 countries and find that in high gender bias countries female entrepreneurs are more likely to opt out of the loan application process and to resort to informal finance even though banks do not appear to actively discriminate against them these results are not driven by credit risk differences between female and male owned firms or by any idiosyncrasies in the set of countries in our sample

a re examination of exposure to exchange rate risk the impact of earnings management and currency derivative usage abstract in an attempt to explain the weak evidence of priced exchange rate risk we hypothesize that in addition to currency derivative usages earnings management serves as another factor contributing to a reduction in exchange rate exposure our evidence reveals that earnings management activities particularly those undertaken for the purpose of income smoothing significantly reduce firm specific exchange rate exposure and that such role is particularly important if appropriate currency derivative instruments are limited these results complement prior attempts to explain the puzzle of unpriced exchange rate risk the investigation also highlights the importance of recognizing different managerial purposes behind discretionary accruals

is roger federer more loss averse than serena williams using data from the high stakes 2013 dubai professional tennis tournament we find that compared with a tied score i male players have a higher serve speed and thus exhibit more effort when behind in score and their serve speeds get less sensitive to losses or gains when score difference gets too large and ii female players do not change their serve speed when behind while serving slower when ahead thus male players comply more with prospect theory exhibiting more loss aversion and reflection effect our results are robust to controlling for player fixed effects and characteristics with player random effects

exchange rate exposure hedging and the use of foreign currency derivatives abstract we examine whether firms use foreign currency derivatives for hedging or for speculative purposes using a sample of s p 500 nonfinancial firms for 1993 we find evidence that firms use currency derivatives for hedging as their use significantly reduces the exchange rate exposure firms face we also find that while the decision to use derivatives depends on exposure factors i e foreign sales and foreign trade and on variables largely associated with theories of optimal hedging i e size and r d expenditures the level of derivatives used depends only on a firm s exposure through foreign sales and trade

event related exchange rate forecasts combining information from betting quotes and option prices betting quotes provide valuable information on market implied probabilities for outcomes of events such as elections or referendums which may have an impact on exchange rates we generate exchange rate forecasts around such events based on a model that combines risk neutral event probabilities implied from betting quotes with risk neutral exchange rate densities extracted from currency option prices its application to predict exchange rates around the brexit referendum and the u s presidential elections shows that these forecasts conditional on the respective outcomes were accurate and markets were able to separate their views on the likelihood and the impact of these events

on the determinants of corporate hedging finance theory indicates that hedging increases firm value by reducing expected taxes expected costs of financial distress or other agency costs this paper provides evidence on these hypotheses using survey data on firm s use of forwards futures swaps and options combined with computstat data on firm characteristics of 169 firms in the sample 104 firms use hedging instruments in 1986 the data suggest that firms which hedge face more convex tax functions have less coverage of fixed claims are larger have more growth options in their investment opportunity set and employ fewer hedging substitutes
