combined use of foreign debt and currency derivatives under the threat of currency crises the case of latin american firms abstract we investigate the determinants of firms use of foreign currency derivatives in emerging markets exposed to currency crises we develop a model where a firm with international orientation chooses its optimal foreign debt and hedging ratio in the context of highly volatile exchange rate periods in five latin american countries we calibrate the model on adrs we find theoretical and empirical evidence that country specific factors i e aggregate exposure of a country to a crisis explain significantly part of our firms foreign debt and hedging policy as opposed to literature on firms in developed markets we claim that derivative markets have been effective tools for firms in these countries at least in the post crisis era

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

international evidence on the determinants of foreign exchange rate exposure of multinational corporations in this paper we explore some of the potential determinants of foreign exchange fx exposure and firm value we contribute to previous research on stock returns and firm value as we have access to a unique survey database and can include as determinants in our empirical analysis the objectives and emphasis on risk management as well as considering previous factors including the nature of the business environment we can also examine any regional influences as our sample includes uk us and asia pacific multinational companies mncs as predicted by theory we find some evidence that mncs with greater foreign operations have a larger magnitude of fx exposure however our proxy for the emphasis of fx management does not have the predicted negative association with the magnitude of fx indicating that managers may focus on short term cash flows in their fx management rather than firm value with regard to the potentially differential regional role of our variables a range of interesting results is found arguably in our most notable such finding we see that the contribution of overseas business to total revenues has no association with the magnitude of fx exposure for us mncs it has a positive role for uk mncs consistent with theory and a negative role for asia pacific mncs which could be explained by macroeconomic and or financial characteristics of the mncs in the sample

the gender gap fertility and growth changes in fertility have long been recognized as important correlates of economic growth with the relationship between the level of fertility and the level of income per capita being one of the strongest observable correlations in cross country data this paper examines the linkages between fertility and growth theory the structure of the model is presented in sections on production couples decision making system dynamics and steady state equilibria the first component of the model is that increases in capital per worker raise womens relative wages since capital is more complementary to womens labor input than to mens the second component is that increasing womens relative wages reduces fertility by raising the cost of children more than household income finally lower fertility raises the level of capital per worker a positive feedback loop generates demographic transition a rapid decline in fertility accompanied by accelerated output growth

export industry policy and reputational comparative advantage abstract country of origin reputations are endogenized in this paper and it is shown that otherwise identical countries can be correctly perceived as differing in their percentage of high quality producers these self fulfilling reputations determine not only the average quality of a country s exports but also the type of products in which a country specializes hence the pattern of international trade can be determined by this reputational comparative advantage an inferior country of origin reputation leads to lower national welfare therefore several trade and industrial policies that can improve country of origin reputation are examined

international trade and labor market discrimination textabstractwe embed a competitive search model with labor market discrimination or nepotism into a two sector two country framework in order to analyze how labor market discrimination impacts the pattern of international trade and also how trade trade affects discrimination discrimination or nepotism reduces the matching probability and output in the skilled labor intensive differentiated product sector so that the country with more discriminatory firms has a comparative advantage in the simple sector as countries alter their production mix in accordance with their comparative advantage trade liberalization can then reinforce the negative effect of discrimination on development in the more discriminatory country and reduce its effect in the country with fewer discriminatory firms similarly the profit difference between non discriminatory and discriminatory firms increases in the less discriminatory country and shrinks in the more discriminatory one in this way trade can further reduce discrimination in a country where it is less prevalent and increase it where it is more firmly entrenched

hedging and coordinated risk management evidence from thrift conversions we provide an explanation for hedging as a means of allocating rather than reducing risk we argue that when increases in total risk are costly firms optimally allocate risk by reducing increasing exposure to risks that provide zero positive economic rents our evidence shows that mutual thrifts that convert to stock institutions increase total risk following conversion consistent with their increased abilities and incentives for risk taking they achieve this increase by hedging interest rate risk and increasing credit risk we provide some evidence that risk management activities are related to growth capacity and management compensation structure attained at conversion

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

business ethics and the decision to adopt golden parachute contracts empirical evidence of concern for all stakeholders golden parachutes are often viewed as a form of excessive compensation because they provide senior management with substantial payouts following an acquisition while other stakeholders are subjected to layoffs disrupted business relationships and other negative externalities using a sample of s p 500 firms an economic and ethical justification for this type of contract is given golden parachutes ensure effective corporate governance that in turn preserve the firm s value for all stakeholders boards of directors enter into parachute agreements to protect recently hired ceos human capital during periods of financial uncertainty and thus potential takeover activity from an ethics viewpoint golden parachutes are valuable to all stakeholders because they encourage merger or acquisition in lieu of bankruptcy

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

what drives the commodity price beta of oil industry stocks we test theoretical drivers of the oil price beta of oil industry stocks the strongest statistical and economic support comes for market conditions type variables as the prime drivers namely oil price bond rate volatility of oil returns and cost of carry though statistically significant exogenous firm characteristics and oil firms financing decisions have less compelling economic significance there is weaker support for the prediction that financial risk management reduces the exposure of oil stocks to crude oil price variation finally extended modelling shows that mean reversion in oil prices also helps explain cross sectional variation in the oil beta

racial discrimination in the labor market theory and empirics we review theories of race discrimination in the labor market taste based models can generate wage and unemployment duration differentials when combined with either random or directed search even when strong prejudice is not widespread but no existing model explains the unemployment rate differential models of statistical discrimination based on differential observability of productivity across races can explain the pattern and magnitudes of wage differentials but do not address employment and unemployment at their current state of development models of statistical discrimination based on rational stereotypes have little empirical content it is plausible that models combining elements of the search models with statistical discrimination could fit the data we suggest possible avenues to be pursued and comment briefly on the implication of existing theory for public policy jel j15 j31 j64 j71

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

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

discrimination in an equilibrium search model i construct an equilibrium search model where some employers have a distaste for hiring minority workers and show that this bias results in economic discrimination against minority workers although only unprejudiced firms hire minority workers minority workers receive lower wages than workers not facing discrimination whenever any employers in the market have a distaste for minority workers one implication of the model is that gender or racial wage differentials understate the utility loss from discrimination in addition the wages of minority workers increase when their proportion increases in the labor market

the efficiency of alternative policies for the ec s common agricultural policy comment in a recent article in this journal de gorter and meilke dgm compare the redistributive efficiency of agricultural price support policies under alternative assumptions about accompanying supply control measures using a long run supply curve which is assumed invariant with respect to policy choice dgm assess the consumer taxpayer cost per ecu of total producer surplus under different policies and conclude that individual production quotas followed closely by a two tier price policy are preferable to price reductions or a coresponsibility levy the main substance of this note is that dgm s failure to recognize the underlying structural problems of ec agriculture and to identify the true political target of income support measures renders their approach incapable of yielding a determinate ranking of these measures in terms of their medium term efficiency and invalidates their policy recommenda

trade and search generated unemployment we argue that trade economists should begin to seriously consider environments in which unemployment is carefully modeled we introduce such a model derive several results and compare them to results derived in full employment models we argue that some traditional results are probably too narrow the determinants of comparative advantage and that some results do not generalize to models with unemployment the link between trade and income distribution for employed factors we also show that in some important cases results do generalize there is an extended stolper samuelson theorem that links trade to the distribution of income for searching factors and that our model allows us to address issues that traditional models cannot handle the impact of trade on unemployment and the welfare of the unemployed 1999 elsevier science b v all rights reserved

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

search bargaining and employer discrimination this article analyzes becker s 1957 1971 theory of employer discrimination within a search and wage bargaining setting discriminatory firms pay workers who are discriminated against less and apply stricter hiring criteria to these workers the highest profits are realized by firms with a positive discrimination coefficient moreover once ownership and management are separated both highest profits and highest utility can be realized by firms with a positive discrimination coefficient thus market forces like entry or takeovers do not ensure that wage differentials due to employer discrimination disappear

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

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

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

an equilibrium search matching model of discrimination abstract a model in which firms have incomplete information about workers at the hiring stage is shown to entail discrimination as the unique stable equilibrium outcome even if no agents have a taste for discrimination and groups are ex ante identical groups which are discriminated against e g blacks women earn lower wages and endure longer unemployment spells

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

are disclosures about bank derivatives and employee stock options value relevant abstract the papers by venkatachalam 1996 and aboody 1996 provide some interesting evidence on issues that are important to accounting regulators as well as accounting academics however for econometric as well as economic reasons there are limits to what we can learn from this type of research cross sectional levels studies careful attention to methodological issues in this type of research design can reduce but likely will not eliminate these interpretational difficulties

prices technology and farm size in this paper we construct and empirically test a theory of the agricultural firm which explains the long term growth in farm size in the united states typically the u s farm unit is a family enterprise consequently the ratio of the opportunity cost of farm labor to the price of machinery services determines the size of the farm operation by influencing the machine labor ratio applying the model to u s data we explain virtually all of the growth in the machine labor ratio and in farm size over the 1930 70 period by changes in relative factor prices without reference to technological change or economies of scale

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

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

diseconomies of size with fixed managerial ability managerial ability has important implications for farm growth in this article we first show in a production model that increasing output with a fixed level of managerial ability can lead to a decrease in profits next we discuss the effect that managerial ability has on economies of size in the empirical part economies of size are estimated for a sample of dairy farms using a proxy for managerial ability which is calculated as a technical efficiency index the results show that increasing farm size while holding managerial ability constant can be an important source of diseconomies of size copyright 2003 oxford university press

common property equality and development the appeal of common property ideas may be traced in large measure to the fact that they seem to embody widely held values of equality on the other hand empirical examination of common property institutions reveals that they can coexist with significant inequality in this paper the relationship between common property and equality is examined it is argued that the role of common property can only be understood in the context of the associated private property institutions common property in agriculture is interpreted as part of a system based on small scale peasant proprietorship of arable land common property institutions provide a method of capturing scale economies and thereby increasing the efficiency of small scale proprietorship in competition with large scale production based on wage labor

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

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 use of foreign currency derivatives corporate governance and firm value around the world abstract this paper examines the impact of currency derivatives on firm value using a broad sample of firms from thirty nine countries with significant exchange rate exposure derivatives can be used for managers self interest for hedging or for speculative purposes we hypothesize that investors can appeal to a firm s internal firm level and external country level corporate governance to draw inferences on a firm s motive behind the use of derivatives since well governed firms are more likely to use derivatives to hedge rather than to speculate or pursue managers self interest consistent with this explanation we find strong evidence that the use of currency derivatives for firms that have strong internal firm level or external country level governance is associated with a significant value premium

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

institutions and moral hazard in open economies i investigate the interaction between international trade and national institutional development in an environment characterized by heterogeneous individuals choosing their education levels to maximize their utilities and institutions alleviating moral hazard by allowing managers to better observe and verify the productive efforts of workers liberalized trade allows institutions to serve as independent sources of comparative advantage in this setting i examine the effect of trade liberalization on the distribution of income in institutionally developed and underdeveloped nations trade affects income via a direct effect on prices and an indirect effect on the incentives to invest in education

revenue neutral tax policies under price uncertainty reply in their comment on my 1990 article yeh suwanakul and mai extend my analysis which focused attention exclusively on firm output to allow for simultaneous endogeneity of price aggregate output and numbers of firms they show that with downward sloping demand industry output adjusts positively to revenue neutral changes in the marginal rate of taxation this result is significant for two reasons first we are more often interested in predictions about aggregate phenomena than we are in predictions about individual firms indeed firm level predictions are frequently irrefutable since firm data are often unavailable second the authors derive their result under a set of conditions that appear to be more general than those invoked in my 1990 article in particular they circumvent the need to invoke specific assumptions about the nature of firms aversions toward risk i consider this a useful extension and i appreciate the careful scrutiny of my paper

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

do analysts understand the economic and reporting complexities of derivatives we investigate whether and how the complexity of derivatives influences analysts earnings forecast properties using a difference in differences design we find that relative to a matched control sample of non users analysts earnings forecasts for new derivatives users are less accurate and more dispersed after derivatives initiation these results do not appear to be driven by the economic complexity of derivatives but rather the financial reporting of such economic complexity overall despite their financial expertise analysts routinely misjudge the earnings implications of firms derivatives activity however we find evidence that a series of derivatives accounting standards has helped analysts improve their forecasts over time

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

racial discrimination in labor markets with posted wage offers we analyze race discrimination in labor markets in which wage offers are posted if employers with job vacancies receive multiple applicants they choose the most qualified but may choose arbitrarily among equally qualified applicants in the model firms post wages workers choose where to apply and firms decide which workers to hire labor market frictions greatly amplify racial disparities so mild discriminatory tastes or small productivity differences can produce large wage differentials between the races compared with the nondiscriminatory equilibrium the discriminatory equilibrium features lower net output lower wages for both white and black workers and greater profits for firms this abstract was borrowed from another version of this item

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

globalization and the gender wage gap there are several theoretical reasons why globalization will have a narrowing as well as widening effect on the gender wage gap but little is known about the actual impact except for a number of country studies the author provides a cross country study of the impact of globalization on the occupational gender wage gap based on the rarely used but most far ranging survey of wages around the world the international labour organization s october inquiry this annual survey was started in 1924 and contains a wealth of information on wages and the gender wage gap for the period 1983 99 there is information on the gender wage gap in 161 narrowly defined occupations in more than 80 countries around the world the author finds the following i the occupational gender wage gap appears to be narrowing with increases in gdp per capita ii there is a significantly narrowing impact of trade and foreign direct investment fdi net inflows on the occupational gender wage gap for low skill occupations both in poorer and richer countries and for high skill occupations in richer countries iii there is no evidence of a narrowing impact of trade but there is evidence of a widening impact of fdi net inflows on the high skill occupational gender wage gap in poorer countries iv wage setting institutions have a strong impact on the occupational gender wage gap in richer countries

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

estimating economies of scope and scale under price risk and risk aversion this study uses duality to examine the effects of excluding output price risk and risk aversion on cost structures using data for kansas wheat and beef cow operations a dual risk model was used to determine multi product and product specific scale economies and economies of scope estimates for these measures were compared with those obtained from a deterministic model the results show that product specific scale economies are over estimated and economies of scope and multi product scale economies are under estimated for the deterministic model compared to the risk model

common property in agricultural production the determination of the property rights structure in agriculture and particularly the role of common property may be viewed as a problem in industrial organization the analysis will focus on the determination of the efficient property rights structure in a multi output technology characterized by economies of scale and scope but also including outputs for which technology is essentially linear given an appropriate analysis of transactions costs common property may be shown to be an efficient alternative to systems based purely on small scale or large scale private property

supply response under proportional profits taxation a striking result in the theory of the competitive firm under certainty is the proposition that a proportional profits tax with full offsets for losses will have no impact on optimal output this result does not apply under uncertainty it is shown that under constant or increasing returns to scale a proportional profits tax will yield an unambiguous expansion in output the same result is shown to hold for the more general rank dependent expected utility rdeu model

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

cost functions under production uncertainty we characterize the cost functions which would be consistent with expected utility maximization when production is uncertain it is not generally possible assuming risk aversion to use only expected output as the constraint in a cost minimization problem in some leading cases cost functions consistent with expected utility maximization are particularly useful because they are devoid of risk preferences

on the origins of comparative advantage this paper proposes a simple theory of international trade with en dogenous technological dierences across countries the core of our analysis lies in the determinants of the division of labor we consider a world economy comprising two large countries with a continuum of goods and one factor of production labor each good is characterized by its complexity de ned as the number of tasks that must be per formed to produce one unit there are increasing returns to scale in the performance of each task which creates gains from specialization and uncertainty in the enforcement of each contract which create transac tion costs the trade obetween these two forces pins down the size of productive teams across sectors in each country under free trade the country where teams are larger specializes in the more complex goods in our model it is the country where the product of institutional qual ity and human per worker capital is larger hence better institutions and more educated workers are complementary sources of comparative advantage in the more complex industries

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

formal but less equal gender wage gaps in formal and informal jobs in urban brazil in developing countries a large share of employees work informally and are not covered by employment protection legislation i study here how gender wage inequality differs across formal and informal jobs in brazil the raw gender wage gap is higher in informal jobs 13 compared to formal jobs 5 but i show that this difference is an artefact of different male and female selection processes first women have better observable characteristics than men and the female advantage is stronger among formal employees second men and women entering formal and informal jobs have different unobservable characteristics controlling for endogenous selection into formal vs informal jobs i find that the gender gap in wage offers is high and increases with education in formal jobs in informal jobs however estimated wage offers are the same for men and women i discuss the potential implications of these findings regarding the effect of labour market regulation on gender wage gaps

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

is farming a constant cost industry measurement of cost size relationships for farming has long been an important area of research in agricultural economics much of this research has had a farm management and production economics orientation and firm industry interdependencies have often been ignored research results stemming from such an orientation should be interpreted with care when used for policy purposes pecuniary externalities may be of greater importance than indicated by research to this time a suggestion is made for treating induced technical change as comparable to a pecuniary externality questions are raised on both theoretical and empirical grounds whether farming in the united states should be considered a constant cost industry for policy purposes

a translog cost function analysis of u s agriculture 1939 77 over the past four decades major changes have occurred in u s agriculture a new era in agricultural production in the united states began in 1939 world war ii gave a boost to agriculture still bogged in the depression productivity increases over the period 1939 77 have been quite impressive measured crudely by the ratio of the indices of output and input the productivity index 1967 100 increased from 59 in 1939 to 119 in 1977 to study this phenomenon a multi input translog cost function incorporating hicks neutral technical change hntc was specified annual timeseries data for the united states was used to estimate the model neoclassical duality theory provides an approach for computing the pairwise elasticities of substitution between inputs for each year as well as the annual own and cross price elasticities of demand for inputs

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

an analysis of the use of derivatives by the canadian mutual fund industry in this paper we examine the use of derivatives by mutual funds in canada first both the incidence and extent of derivatives usage are low second larger growth oriented domestic equity funds are more likely to use derivatives we then compare returns and risks between derivative users and non users with the following findings 1 there exist no differences between users and non users for foreign equity funds 2 for fixed income funds users have higher returns and risks than non users 3 for domestic equity funds users have lower returns but higher risks than non users however the differentials disappear if warrants are excluded from the definition of derivatives

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

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

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

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

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
