bookbuilding and strategic allocation in the bookbuilding procedure an investment banker solicits bids for shares from institutional investors prior to pricing an equity issue the banker then prices the issue and allocates shares at his discretion to the investors we examine the books for 39 international equity issues we find that the investment banker awards more shares to bidders who provide information in their bids regular investors receive favorable allocations especially when the issue is heavily oversubscribed the investment banker also favors revised bids and domestic investors investment banks commonly build a book before pricing an equity issue in the united states it has been standard practice for a number of years in many other countries where fixed price offerings were traditionally used the bookbuilding procedure is becoming increasingly common especially for international equity issues 1 under the formal bookbuilding procedure the investment banker solicits indications of interest from institutional investors such indications consist of a bid for a quantity of shares and might include a maximum price i e a limit price or other details the investment banker uses the information to construct a demand curve the issue price is not set according to any explicit rule but rather based on the banker s interpretation of investors indications of interest he generally sets the price at a level at which demand exceeds supply and then allocates shares to the bidders at his discretion thus the

outlook for solar water heaters in taiwan abstract the share of indigenous energy supply continuously decreases over the last two decades in taiwan the development and use of renewable energy sources and technologies are becoming vital for the management of energy supply and demand for promotion of solar water heaters the incentive programs were firstly initiated in the period of 1986 1991 and re initiated from 2000 to the present these programs create an economic incentive for the end users and have a drastic effect on the popularization of solar water heaters to further promote solar water heaters during the current incentive program period several key factors are addressed in addition to the cost of solar water heaters and energy price index the potential market of solar water heaters in taiwan is associated with the climatic conditions population structure urbanization building type of housing and status of new construction

risk aversion and the recommended hedging ratio in a recent article in this journal kahl reviewed the existing literature on the determination of optimal futures and cash market positions the optimal hedging ratios were found to depend on whether the cash position was treated as endogenous or predetermined and some general implications were set forth the surprising conclusion was that the optimal hedging ratio is independent of the individual s risk aversion even though the optimal positions in the cash and futures markets are themselves not independent of the risk parameter kahl demonstrates that this conclusion

discounting and underpricing in seasoned equity offers abstract expected discounting in seasoned equity offers is a cost of uncertainty about firm value marketing new shares and acquiring information that raises the offer price stockholders incorporate predictable discounting in stock prices when equity offers are first announced the surprise component of discounting reflecting the lead bank s final adjustment to the offer price releases information that often causes economically large price swings on the offer day disparities between the issuer s closing price and the price suggested in the lead bank s final order book are a primary source of information the discount surprise appears to be used by lead banks to update capital suppliers with that eleventh hour information before they commit their funds

an investigation of market microstructure impacts on event study returns we investigate the importance of bid ask spread induced biases on event date returns as exemplified by seasoned equity offerings by nyse listed firms we document significant negative return biases on the offering day which explain a large portion of the negative event date return documented in the literature buy sell order flow imbalance is prominent around the offering and induces a relatively large spread bias if order imbalances are suspected the researcher can use returns calculated from the midpoint of the closing bid and ask quotes instead of returns calculated from closing transaction prices to avoid this return bias several studies document the impact of bid ask spreads on security return patterns which appear inconsistent with the informational efficiency of capital markets phillips and smith 1980 find spread induced bias to be important in explaining apparent arbitrage opportunities in the option markets lakonishok and smidt 1984 uncover evidence suggesting a relation between bid ask spreads and turn of the year seasonality in stock returns 1 keim 1989 and porter 1989 further document the empirical importance of

futures market equilibrium with heterogeneity and a spot market at harvest abstract this paper studies equilibrium in the futures market for a commodity in a single good economy which is populated by heterogeneous producers and speculators the commodity is traded only in the spot market at harvest whereas futures contracts written on the commodity are traded continuously the model illustrates the role of heterogeneity and non tradeness in a futures market equilibrium the results show that the futures price is driven by aggregate wealth rather than the spot price as in other models and that the futures price process is a simple one which depends on the relative risk process

the minimum variance hedge ratio under stochastic interest rates in an environment where interest rates are stochastic we examine the case of a pure hedger endowed with a fixed position in a long term bond in contrast to conventional wisdom according to which the difference between hedging through forward contracts and futures is immaterial it turns out that the minimum variance hedge ratio using forwards comprises two terms instead of one only when using futures the magnitude of the difference between the two hedge ratios may be important under some plausible assumptions this result is due to the presence of additional interest rate risk that bears on the profit and loss statement associated with the forward position this sheds some additional light on the respective features of forward and futures contracts written on interest rate sensitive securities

optimal currency risk hedging abstract this paper investigates the optimal hedging strategy of a domestic expected utility maximizer endowed with a temporarily non traded position in a foreign investment the domestic and foreign yield curves the exchange rate between the two involved currencies and the foreign investment value are stochastic and obey fairly general diffusion processes we compare the hedger s optimal strategies using either exchange rate forward contracts or futures contracts for both strategies the optimal number of contracts held can be broken down into several components having clear economic interpretations however while futures contracts are known in such a context to be more difficult to price than their forward counterparts the optimal strategy using them is simpler this is due to the fact that when forward contracts are used incurred profits or losses that accrue to the investor s wealth at each instant are locked in in the forward position up to the contract maturity thus discounting these gains or losses back at the current date brings about an interest rate risk therefore the investor s hedging strategy itself generates an additional risk which in turn induces the need for additional hedging the magnitude of the difference between the two hedge ratios may be significant under a set of plausible assumptions since in general financial markets are not complete the additional interest rate risk cannot be perfectly hedged hence the marking to market mechanism that characterizes futures contracts and allows for the complete elimination of this risk is valuable for risk averse agents

commodity price forecasting with large scale econometric models and the futures market this paper compares the accuracy of major commercial price forecasts for corn wheat soybeans soybean oil soybean meal cotton live cattle and hogs the price forecasting information in futures prices is evaluated by comparison the results among commercial forecasters are mixed but futures prices perform relatively better on average although not universally so these results have important implications for operational risk management

payback period for residential solar water heaters in taiwan abstract taiwan is a leaf shaped island straddling the tropic of cancer with abundant and reliable supply of solar energy under the individual circumstances solar radiation ambient temperature and hot water consumption pattern solar heating could be economically competitive with conventional heating fuels electricity natural gas or liquefied petroleum gas in this context the market of residential solar water heaters swhs in taiwan has been highly developed with subsidy programs offered by the government of taiwan so far next the economic viability of residential swhs is determined by the life cycle savings this study develops a procedure for estimating the payback period of residential swhs in terms of operation cost and effective energy savings over conventional heating fuels a case study in southern taiwan indicates that the increase in daily load volume per area of solar collector installed has a beneficial effect an end user should determine the economically optimal solar collector area of an swh according to the hot water consumption pattern of each household payback period is shorter when the substituted conventional fuel is electricity with the subsidy program an swh is in a favorable situation when compared with an electrical water heater findings of the present study would assist partially system design of residential swhs and help accrue more monetary benefit to the end users

why do farmers have so little interest in futures markets a farm financial model with leverage and investment in two farm enterprises is specified the model is extended to incorporate futures hedging and the separation theorem is used to show that optimal hedging is zero the assumption of a risk free asset is relaxed and while this leads to a violation of the separation theorem the result that optimal hedging is zero is maintained providing that futures markets are efficient it is concluded that if capital markets are efficient then farmers will have little interest in futures markets except to speculate

on the accuracy of the mean variance approximation for futures markets abstract simple approximate fomulae for the volume and gains from futures trading are derived using the mean variance model the errors involved are exactly quantified and shown to be negligible for the futures price and welfare gains though potentially larger for volumes

technical and economic performance of residential solar water heating in the united states abstract this paper examines the regional technical and economic performance of residential rooftop solar water heating swh technology in the u s it focuses on the application of swh to consumers in the u s currently using electricity for water heating which currently uses over 120 billion kwh per year the variation in electrical energy savings due to water heating use inlet water temperature and solar resource is estimated and applied to determine the regional break even cost of swh where the life cycle cost of swh is equal the life cycle energy savings for a typical residential consumer a swh system will reduce water heating energy demand by 50 85 or a savings of 1600 2600 kwh per year for the largest 1000 electric utilities serving residential customers in the united states as of 2008 this corresponds to an annual electric bill savings range of about 100 to over 300 reflecting the large range in residential electricity prices this range in electricity prices along with a variety of incentives programs corresponds to a break even cost of swh in the united states varying by more than a factor of five from less than 2250 system to over 10 000 system excluding hawaii and alaska despite a much smaller variation in the amount of energy saved by the systems a factor of approximately one and a half we also consider the relationships between collector area and technical performance swh price and solar fraction percent of daily energy requirements supplied by the swh system and examine the key drivers behind break even costs

the choice of equity selling mechanisms abstract this paper examines the impact of information asymmetry and monitoring of managers on the choice between public offerings and private placements three key findings emerge first private placement firms have higher information asymmetry than public offering firms second private placement investors do not engage in more monitoring than public offering investors finally discounts for private placements sold to managers are higher than discounts for private placements in which managers do not participate the final two findings cast doubts on the widely held view that private placements are motivated by a demand for enhanced monitoring

on the optimal hedge of a nontraded cash position in this paper we focus on the optimal demand for futures contracts by an investor with a logarithmic utility function who attempts to hedge a nontraded cash position when the analysis is conducted in the cash commodity price space we show that the value function associated with the bernoulli investor program is not additively separable thus suggesting that this investor hedges against shifts in the opportunity set as represented by the commodity price by establishing the equivalence between the cash formulation of the problem and the wealth formulation we are able to analyze the problem in the wealth commodity price space in this space we show the additive separability of the value function when the futures settlement price process is perfectly locally correlated with the commodity price process the demand for futures in this instance is composed of a a mean variance term and b a minimum variance component that is a classic feature of models with nontraded assets since the first best nonmyopic optimum is attained however the deviation from a mean variance demand should not be interpreted as the expression of a nonmyopic behavior but rather as an attempt to restore a first best optimum on the other hand when the correlation between the futures price and the underlying commodity price is imperfect in general the value function does not separate additively the first best solution cannot be attained and the optimal futures trading strategy involves a hedging term against shifts in the opportunity set in the classic dynamic portfolio problem the investor selects a trading strategy in risky and riskless assets so as to maximize his or her expected lifetime utility in this environment where all assets can be freely traded the logarithmic investor behaves myopically to the extent that he or she ignores shifts in the opportunity set when making current choices samuelson 271 mossin 24 hakansson 16 merton 22 in particular in models with continuous trading it turns out that the value function corresponding to the investor s program is additively separable in wealth and state variables the implication is that his or her behavior will be myopic i e that his or her demand functions for assets will be of the pure meanvariance efficiency type and in particular will not include any dynamic hedging components that are characteristic of financial markets with shifting opportunities in this paper we investigate the structure of the bernoulli investor s demand functions in the situation where one asset cannot be freely traded in the market

issuing costs to existing shareholders in competitive and negotiated underwritten public utility equity offerings abstract this paper presents the results of an empirical investigation of whether there is any difference in the cost incurred by public utilities if they issue new equity through a negotiated or competitive underwriting we conclude that the expected cost of a competitive offer is less than the expected cost of a negotiated offer but that the variance of the cost is substantially greater with a competitive offer these results are interesting because most public utilities use negotiated underwriting unless forced by regulation to use competitive offers this paper is also an addition to the growing agency theory literature

the time pattern of hedging and the volatility of futures prices the paper proposes a multi period model of hedging which allows for a futures position to be revised within the cash market holding period within this framework we assess the robustness of the two period theory of hedging when generalized to many periods we characterize the normal time path of a hedge and the way it is affected by the requirement that futures accounts mark to market daily finally we show how the resolution of production uncertainty over time affects hedging behavior and determines the volatility of futures prices in the large literature on hedging in futures markets the principal analytical accounts of hedging are framed in a two trade date setting an agent commits himself now to a future purchase or sale of a good whose cash price later is uncertain this risk is hedged by purchase or sale of an appropriate number of futures contracts and holding this futures position until the cash transaction is realized in the present paper we formulate a multi period model of hedging which allows for the futures position to be revised within the cash market holding period the resulting analysis captures an important institutional reality that is absent in a two trade date model namely the fact that the day to day fluctuations of the futures price will generate a series of random cash flows over the period during which a futures position is held this is due to the requirement that futures accounts mark to market daily within this framework we address a number of issues first we assess the robustness of the two period theory of hedging when generalized to many periods second we characterize the normal time path of a hedge and contrast futures and forward contracts from the perspective of an individual hedger finally we show how the resolution of production uncertainty over time affects hedging behaviour and determines the volatility of futures prices while the literature on asset demand in a multiperiod setting is large futures markets are specifically treated in a limited number of studies grauer and litzenberger 1976 are concerned principally with characterizing the relation of spot and futures prices in a market for a storable periodically produced commodity they offer a rationale for positive stock holding in markets where spot price exceeds the futures price richard and sundaresan 1980 are also concerned primarily with characterizing price behaviour since they posit identical consumers in equilibrium individual holdings of futures are zero there is no hedging activity in the sense that we understand it breeden 1980b analyzes the optimal futures position sizes in a multiperiod setting his framework is more general than ours in that his is a multi good multi asset model where preferences

an equilibrium analysis of hedging with liquidity constraints speculation and government price subsidy in a commodity market we develop a simple commodity model to analyze i the effects of hedgying with liquidity constraints due to producers inability to bear unlimited trading losses ii the role of speculation in the process of risk allocation between consumers and producers and iii the equilibrium implications of government price subsidies to the producers we find that 1 liquidity constraints can cause futures prices to exhibit mean reversion which then makes speculation profitable 2 speculation tends to make futures price volatility an increasing function of futures price and 3 government price subsidy if actively hedged by the producers serves to lower the futures risk premium and reduce futures volatility commodity spot and futures prices are determined by the following types of market participants producers consumers speculators and governments producers have generally taken short futures positions in order to hedge against price declines consumers have generally taken long futures positions in order to hedge against price increases speculators who neither produce nor intend to consume the commodity are present in the spot and futures markets for the purpose of making a profit governments play significant roles in the markets by providing producers with various support programs and in some cases by directly intervening in the markets to affect commodity prices or adjust inventory levels the traditional approach to commodity futures pricing has been based on the theory of storage 1 as fama and french 1987 1988 show this approach to commodity pricing is particularly useful for explaining the basis movement as a function of inventory levels based on the hypothesis that the marginal convenience yield on inventory declines at a decreasing rate as

methods for selecting the optimal dynamic hedge when production is stochastic a dynamic hedging problem with stochastic production is solved the optimal feedback rules recognize that future hedges will be chosen optimally based on the most current information the resulting distribution of revenue is analyzed numerically this analysis enables the hedger to select his appropriate level of risk aversion

the rationale of the mean standard deviation analysis skewness preference and the demand for money publisher summary this chapter discusses the rationale of the mean standard deviation analysis skewness preference and the demand for money in january 1969 issue of the review of economic studies karl borch and martin feldstein separately criticized the widely used mean variance analysis of portfolio selection borch contended that any system of upward sloping mean standard deviation e s indifference curves can be shown to be inconsistent with the basic axiom of choice under uncertainty he pointed out that one can always pick any two points on an upward sloping indifference curve to represent two bernoulli distributions with probability 1 p of gaining the same amount x in both the cases and probability p of gaining y1 in the case of one distribution and y2 in the case of the second distribution with y2 y1 if the second distribution represents the point to the northeast of the other point then by the dominance axiom the second distribution must be preferred to the first which contradicts the basic meaning of indifference curves feldstein by using a log utility function and a lognormal distribution for investment outcome showed that e s indifference curves for a risk averter need not be convex downwards though upward sloping they would change from convex to concave once the standard deviation of the outcome exceeds the mean multiplied by on the face of it this seems to suggest that risk aversion might decrease as risk is increased beyond a certain extent

green transition of energy systems in rural china national survey evidence of households discrete choices on water heaters abstract energy systems in rural china are experiencing a transition from traditional fossil fuels to renewables this paper aims to investigate the potential factors that influence the choices of rural residents regarding water heaters with a focus on the low carbon transition to solar water heating systems to this end a face to face questionnaire survey is undertaken with 3404 rural households randomly selected among 12 representative provinces a comprehensive set of discrete choice modelling approaches were used the empirical results show that 1 sociodemographic variables have significant effects on residents first stage choice of a water heater to buy or not to buy but few effects on the second stage decision to choose electric lpg or solar water heaters which type to buy 2 information spillover is important to facilitate the usage of water heaters particularly of solar products 3 the electricity price which is regulated at a very low rate has no apparent effect on the choice of solar water heaters 4 government subsidy has a significant effect in the first stage but no differentiated effect on the decision choice in the second stage policy and managerial implications are presented to speed up the ongoing low carbon transition of energy systems in china

theory of the firm with joint price and output risk and a forward market expected utility maximizing farmers facing just price risk or both price risk and quantity risk behave similarly in the absence of a forward market if forward contracting is possible that is not true because variation in the commodity price affects a farmer s wealth through the value of his futures position the value of his output and through the covariance between price and output this covariance affects a farmer s optimal scale of production his optimal forward position and the interrelationship between the scale of production and forward trading

toward a positive economic theory of hedging the hedging models developed over the last half century are evaluated for their ability to explain the actual hedging behavior of the various economic agents this evaluation shows a total lack of a reasonable positive model of hedging behavior while each class of existing models predicts some observed behavior none is able to predict the broad range of actions that is easily observed in the real world in this paper i develop such a model and include a plausible and coldly rational economic explanation for why farmers don t hedge at all while merchandisers with identical risk attitudes will fully hedge

local market of solar water heaters in taiwan review and perspectives for promotion of solar water heaters in taiwan incentive programs were first initiated from 1986 to 1991 and re initiated from 2000 to the present the subsidies create an economic incentive for the end users and have been rather instrumental at the initial stage of each program but lost their significance thereafter to analyze the behavior of the major actors in the local market two questionnaires were developed one was addressed to sales and distribution agents while the other one consisted of person to person interviews with household owners the market driven mechanism is a multi parametric phenomenon other than the capital cost and energy price cost to benefit architectural type of buildings or degree of urbanization and household composition play the major roles in market diffusion

the optimal spread and offering price for underwritten securities abstract the paper develops the net proceeds maximization theory explaining how the spread and offering price are determined in all underwritten offerings in the u s the theory yields solutions for the optimal spread and offering price for all underwritten securities and it yields comparative statics that explain the cross sectional variation in actual spreads and initial returns across different types of underwritten securities the theory also suggests two alternative explanations to the ones offered by chen and ritter j finance 55 2000 1105 for the clustering of unseasoned equity offerings spreads at 7

the effects of supply and interest rate shocks in commodity futures markets this paper extends previous studies of futures markets to highlight the role of expectations in the analysis of supply and interest rate shocks shocks which are expected to be permanent generally will create larger movements in spot and futures prices than shocks which are regarded as transitory further the reactions of spot and futures prices may differ both qualitatively and quantitatively depending on whether new information refers to events in the current period or to likely developments in some future period the results demonstrate the potential importance of capturing expectations effects in empirical studies of futures market behavior

market volatility and the dynamic hedging of multi commodity price risk commodity cash and futures prices experienced a severe boom and bust cycle between 2006 and 2009 increases in commodity price volatility have raised concerns about the usefulness of commodity futures and options as risk management tools dynamic hedging strategies have the potential to improve risk management when conditional co variances depart significantly from their unconditional long run counterparts and may be useful to decision makers despite their greater complexity and higher transaction costs we propose a nonparametric copula based generalized autoregressive conditional heteroscedastic npc garch approach to estimate time varying hedge ratios and evaluate the benefits of dynamic hedging during four sub periods between 2000 and 2011 using a stylized texas cattle feedlot management problem the npc garch approach allows for a flexible nonlinear and asymmetric dependence structure between cash and futures prices for different commodities we find that npc garch dynamic hedging performs bette

signalling and the pricing of new issues this paper develops a signalling model with two signals two attributes and a continuum of signal levels and attribute types to explain new issue underpricing both the fraction of the new issue retained by the issuer and its offering price convey to investors the unobservable intrinsic value of the firm and the variance of its cash flows many of the model s comparative statics results are novel empirically testable and consistent with the existing empirical evidence on new issues in particular the degree of underpricing which can be inferred from observable variables is positively related to the firm s post issue share price

futures markets and commodity options hedging and optimality in incomplete markets abstract this paper examines the allocational roles of futures markets and commodity options in multi good and multi period economies in a continuous time model with time additive utilities and homogeneous beliefs trading in unconditional futures contracts the market portfolio and a riskless asset gives any pareto optimal allocation individuals optimal holdings of futures contracts in the continuous time model are related to their consumption bundles and to their risk tolerances it is shown that both hedging and reverse hedging behavior are possible in the general model with discrete trading options on portfolios of commodity options are shown to permit any unconstrained pareto optimal allocation

an empirical investigation of ipo returns and subsequent equity offerings abstract several recent papers present signaling models in which firms underprice their initial public offerings of equity ipos so that they can subsequently issue seasoned equity at more favorable prices we test the implications of these models we find a positive relation between ipo underpricing and the probability and size of subsequent seasoned offerings although these results are consistent with the implications of the signaling hypotheses the economic significance appears weak we conduct additional tests to evaluate other explanations for these findings and find the alternatives more compelling

optimal currency hedge ratios and interest rate risk abstract the objective of this article is to provide a framework for the interpretation of the optimal currency hedge ratios on foreign investments taking into account interest rate risk this is made possible by using a continuous time setting in the spirit of merton 1969 we focus on the importance of the interest rate differential forward basis in setting the optimal currency hedge because of the influence of interest rates on exchange rates more specifically we consider two discount bonds a domestic and a foreign one which follow stochastic processes possibly correlated with the other state variables of the model it is shown that the optimal hedge ratio can be split into five components a a macro economic component which is a function of the volatility of the interest rate differential and its covariance with currency movements this term depends on the currency considered but not on the asset being hedged b an asset specific term which is directly related to the covariance of the foreign currency asset return with exchange and interest rate movements c a speculative term function of the investor s risk preference and of the conditional risk premium on the exchange rate and d two stochastic opportunity set hedging terms the analysis of the optimal hedge ratio is illustrated on the period december 1970 1989 for stock and bond investments in seven countries jel g15 f31

is the ipo pricing process efficient this paper investigates underwriters treatment of public information throughout the ipo pricing process two key findings emerge first public information is not fully incorporated into the initial price range while the economic magnitude of the bias is small it is puzzling because it is not clear who benefits from it further it indicates that the filing range midpoint is not an unbiased predictor of the offer price as prior literature has assumed second while public information is similarly not fully incorporated into the final offer price the small economic significance of this relation indicates that the ipo pricing process is almost efficient

the impact of global equity offerings this article examines the impact of u s firms issuing equity in multiple markets we compare the stock price reactions to announcements of global equity offers to a control group of issues offered exclusively in the domestic u s market all else equal the adverse price reaction that typically accompanies equity issuance is reduced by 0 8 percent when some shares are sold abroad the overall evidence suggests global offers are effective in expanding demand and reducing the price pressure effects associated with share issuance the benefits of global offers appear to be associated with an increase in the number of foreign shareholders the search for new capital markets and lower costs of capital is an ongoing search for most firms in recent years the number of u s firms issuing common equity in international markets has increased significantly in 1985 u s firms raised 89 million through follow on equity offers in foreign markets and this amount increased to 18 915 million in 1995 a greater than 200 fold increase in nominal terms this paper focuses on follow on global equity issues by u s firms and attempts to assess why firms widely acknowledged to have access to broad and deep domestic capital markets increasingly seek to raise equity abroad the global equity offerings we examine involve a simultaneous sale of common equity at the same offer price in the u s market and one or more international markets we examine the characteristics of the issuers and issues and investigate to what extent the wider distribution of shares affects the pricing and costs of these issues our main line of inquiry examines whether the distribution of shares to multiple markets results in a higher offer price for equity shares than would be obtained had the shares been sold exclusively in the u s market domes

seasonal patterns of futures hedging and the resolution of output uncertainty abstract optimal futures hedging is examined in a two good model with stochastic output and sequential information arrival a producer s optimal hedge depends on demand elasticity sensitivity of his output to weather his correlation with aggregate output and how rapidly his output uncertainty is resolved relative to other producers during different seasonal periods because regional output uncertainties are resolved at different times the optimal futures position of a grower will commonly reverse in direction during the crop year a producer with non stochastic output who faces price risk arising from demand shocks may remain unhedged or even maintain a long position

optimal spreading when spreading is optimal abstract this paper assumes an investor who has a non traded position operating in a stochastic interest rates environment the investor trades continuously either distinct futures contracts or distinct forward contracts in order to maximize his expected utility of terminal wealth in order to reach the welfare level of the first best optimum the investor must incorporate into his portfolio either two distinct futures contracts or two distinct forward contracts the optimal forward contracts dynamic spreading strategy has two components a speculative component and a minimum variance hedging component the minimum variance hedging component is composed of a short position in the nearby contract and a long position in the deferred contract the speculative component serves to replicate the growth optimum portfolio the speculative component is composed of a short position in the contract which is the most negatively correlated with the growth optimum portfolio and a long position in the other contract the marking to market procedure of the futures positions forces the investor to hold less futures contracts than the corresponding forward contract positions the analysis is also extended to incomplete markets and to inter market spreading

forward and futures markets and the competitive firm under price uncertainty recent remedies for managing the output price risk faced by a competitive firm sometimes include the prescription of hedging this practice usually entails combining spot market sales with trading opportunities in forward or futures markets the forward hedge represents a risk free price the futures hedge offers a risky alternative which arises because of basis the variable relationship between the spot and futures quotations rather than treating forward and futures as mutually exclusive or as perfect substitutes a competitive firm can carefully construct a portfolio which combines spot forward and futures positions holthausen 9 and feder just and sclmitz 5 hereafter fjs initiate an extensive discussion of a risk averse firm which uses futures contracts when faced with an uncertain output price but no basis risk both articles employ general utility and density functions to derive their results their conclusions include independence of the production decision from the probability density of the spot price and the firm s degree of risk aversion extensions of these two articles usually focus on the robustness of the separation conclusion to either the addition of basis or the addition of production uncertainty to the models the risk free characteristic that holthausen and fjs attribute to futures contracts really better describes a forward contract jarrow and oldfield 11 paul heifner and helmuth 17 and many others document the importance of recognizing the unique charapteristics of these two different types of contracts batlin 2 builds on the holthausen and fjs foundation by adding basis risk to his model fjs explicitly qualify their model as applicable to only those commodities with little or no production uncertainty subsequent articles augment their analysis with the condition of stochastic production chavas and pope 3 anderson and danthine 1 marcus and modest 15 ho 8 and grant 6 all include production uncertainty in different permutations of the fundamental model those which simultaneously include both basis and production risk achieve analytical solutions by assuming specific utility or density functions

corporate earnings and financings an empirical analysis this article examines the long term behavior of corporate earnings around three corporate financing events sales of common stock convertible bonds and straight bonds the article shows that earnings declined for all issuers and that more capital is raised the larger the earnings decline these findings indicate that external financings are motivated by earnings declines no evidence is found of a relationship between the size of the subsequent earnings downturn or the amount of capital raised and stock price reactions to the financing announcements these findings suggest that security sales did not systematically provide new information about either the magnitude of subsequent earnings downturn or the amount of financing copyright 1990 by the university of chicago

optimal consumption policy under uncertain income this paper considers the consumption behavior of a risk averse consumer with a preference for immediate consumption who faces an uncertain income stream and plans for a finite or infinite number of periods the consumer may borrow up to a limit or save where both saving and borrowing are subject to the same positive rate of interest we derive the optimal consumption policies for both finite and infinite planning horizons investigate their characteristics and analyze their economic and behavioral implications

price stabilization in the market for new issues abstract this study examines price stabilization in new equity issues stabilizationtruncates the distribution of post issue prices at a floor price lowering the risk of adverse price moves and hence in a competitive dealer market reducing the bid ask spread using 1 523 nasdao traded firm commitment initial public offerings issued between 1982 and 1987 we find that spreads narrow when the market price is close to the offer price and stabilization is most likely moreover significant negative returns are documented after the hypothesized termination of stabilizing activities suggesting that stabilization and its cessation affect market prices

a reformulation of the portfolio model of hedging the portfolio approach to hedging assumes that the primary motivation for hedging is risk reduction the paper reexamines the portfolio approach to hedging and respecifies the model in such a way that hedge ratios are estimated using returns rather than price levels using the same data set hedge ratios estimated using price levels differ from one while hedge ratios using returns are found to be insignificantly different from one the results do not support the portfolio approach to hedging therefore one must look elsewhere for empirical support for the risk reduction theory of hedging

more reasons why farmers have so little interest in futures markets the use by farmers of futures contracts and other hedging instruments has been observed to be low in many situations and this has sometimes seemed to be considered surprising or even mysterious we propose that it is in fact readily understandable and consistent with rational decision making standard models of the decision about optimal hedging show that it is negatively related to basis risk to quantity risk and to transaction costs farmers who have less uncertainty about prices and those with a diversified portfolio of investments have lower optimal levels of hedging if a farmer has optimistic price expectations relative to the futures market the incentive to hedge can be greatly reduced and finally farmers who have low levels of risk aversion have little to gain from hedging in terms of risk reduction in that the certainty equivalent payoff at their optimal hedge may be little different than the certainty equivalent under zero hedging these reasons are additional to the argument of simmons 2002 who showed that if capital markets are efficient farmers can manage their risk exposure through adjusting their leverage obviating the need for hedging instruments

dealer intermediation and price behavior in the aftermarket for new bond issues municipal bonds trade in decentralized broker dealer markets and are underpriced when issued but unlike equities the average price rises slowly over several days newly issued municipal bonds have high levels of price dispersion and the average price rises because the mix of trade sizes changes over time while large trades occur close to the reoffering price small trades occur between the reoffering price to as much as 5 above the reoffering price using a mixed distribution model we quantify the losses uninformed traders or issuers give up to broker dealers

subsidy programs on diffusion of solar water heaters taiwan s experience abstract financial incentives are essentially one of the key factors influencing diffusion of solar water heaters in many countries two subsidy programs were initiated by the government of taiwan in 1986 1986 1991 and 2000 2000 present respectively those long term national programs are considered to be the driving force on local market expansion in 2008 the regional subsidy programs for solar water heaters were announced by kaohsiung city and kiemen county which resulted in the growth in sales a revised subsidy was also initiated by the government of taiwan in 2009 the subsidy is 50 more however the tremendous enlargement of market size with a high level ratio of subsidy over total installation cost might result in a negative impact on a sustainable swh industry and long term development of the local market which is associated with system design and post installation service this paper aims to address the relative efficiency and pitfalls of those national and regional programs

speculative price economic welfare and the idiot of chance p aul cootner stimulated significant research on the subject of speculative markets in both commodities and equities his papers 1960 1964 1967 were original and provocative one paper began with the statement the subject matter of this paper is bound to be considered heresy i can say that without equivocation because whatever views anyone expresses on this subject are sure to conflict with someone else s deeply held beliefs 1964 p 231 most of the papers concerned with the operation of futures markets in commodities test the efficiency of the market by examining the stochastic nature of futures prices which samuelson refers to as the idiot of chance in particular it is asked whether the price of a futures contract is a martingale cootner s contention which runs counter to the tide of academic writings is that speculative prices are not random walks but are constrained by economically determined barriers 1964 ch 11 the present paper is in the spirit of cootner s thinking about the economic and welfare implications of speculative markets my main conclusions are as follows 1 the optimality of resource allocation defined as the sum of consumer and producer surplus depends upon the accuracy of the forward price at the time production decisions are made as a forecast of the subsequent spot price when consumption occurs the existence or nonexistence of the martingale property of futures prices between these two dates is irrelevant for welfare purposes 2 social loss is a multiple of the square of the forecast error between the forward price and the subsequent spot price expected social loss is irreducible when the forward price is equal to the mathematical expectation of the subsequent spot price 3 the longer the period between the production decisions and the subsequent consumption decisions the greater the bias between the forward price and subsequent spot price 4 it has been claimed that in an efficient market the spot price at time t should just depend upon the price at t 1 and not upon earlier prices it is proved that this situation is neither a necessary nor a sufficient condition for rational expectations 5 therefore there is a tenuous connection between the stochastic nature of speculative price and measures of economic welfare but there is a direct connection between the forecast errors and economic welfare

signalling by underpricing in the ipo market abstract empirical evidence suggests the existence of hot issue markets for initial public offerings in certain periods and in certain industries new issues are underpriced and rationing occurs this paper develops a model consistent with this observation which assumes the firm itself best knows its prospects in certain circumstances firms with the most favorable prospects find it optimal to signal their type by underpricing their initial issue of shares and investors know that only the best can recoup the cost of this signal from subsequent issues

the demand for hedging and the value of hedging opportunities hedging strategies typically assume that hedging is costless and that only one futures market exists when these assumptions are dropped the demand for hedging is shown to depend on basis risk price risk and the hedger s risk preference the marginal and incremental value of hedging opportunities are computed for the general cases of one and two markets and applied to the specific case of pennsylvania dairy input hedging copyright 2000 oxford university press

dynamically optimal after tax grain storage cash grain sale and hedging strategies this article utilizes a stochastic dynamic programming sdp model that considers the state variables of a before tax income b grain storage c quantity of futures position d value of futures position e wheat price and f basis level decision variables are monthly cash grain sales and futures market transactions in comparing the post sample performance of sdp to other marketing strategies over a four year period sdp resulted in 5 961 to 25 021 more wealth than the other strategies considered also these other strategies yielded a standard deviation of after tax income that was 30 to 621 greater than that from the sdp framework

why don t issuers get upset about leaving money on the table in ipos one of the puzzles regarding initial public offerings ipos is that issuers rarely get upset about leaving substantial amounts of money on the table defined as the number of shares sold times the difference between the first day closing market price and the offer price the average ipo leaves 9 1 million on the table this number is approximately twice as large as the fees paid to investment bankers and represents a substantial indirect cost to the issuing firm we present a prospect theory model that focuses on the covariance of the money left on the table and wealth changes our reasoning also provides an explanation for a second puzzling pattern much more money is left on the table following recent market rises than after market falls this results in an explanation of hot issue markets we also offer a new explanation for why ipos are underpriced copyright 2002 oxford university press

managing multiple international risks simultaneously with an optimal hedging model abstract a risk management model based on portfolio theory which accounts jointly for price quantity interest rate and exchange rate risks is developed and applied to cocoa and coffee production and exports in the ivory coast utilizing commodity and financial futures markets jointly the results show that a government export agency can reduce risks from 27 to 89 by following a multicommodity hedging program which manages several risks simultaneously the model and technique developed are applicable to many multiproduct firm and international risk management situations

optimal hedging in a dynamic futures market with a nonnegativity constraint on wealth abstract this paper examines the issue of optimal hedging demands for futures contracts from an investor who cannot freely trade his portfolio of primitive assets in the context of lognormal rather than normal returns and of a constant absolute risk aversion utility function in this context the nonnegativity constraint on wealth is binding and the optimal hedging demands are not identical with those encountered in the bulk of the literature which has largely overlooked this problem negative results concerning the derivation of equilibrium in the futures markets and the computation of the open interests then follow

stock price effects and costs of secondary distributions abstract this study does not support the view that a large number of shares can be sold at the prevailing market price and at a small cost a significant stock price decrease is observed at the initial announcement of secondary distributions the price declines are greater for offerings by officers and directors and for larger offerings but are significant for all types of sellers and for large and small offerings there is no significant price decline at the offering when secondaries are announced in advance underwriting and other selling costs are substantial and are positively related to relative offering size

the impact of price risk on sow farrowings 1967 78 several studies have attempted with varying degrees of success to quantify price risk variables for crops at various levels of aggregation just behrman traill and lin price risk in particular market situations is an empirical issue and difficult to predict ex ante several factors suggest the potential for a risk response in sow farrowings the limited ability of hog futures market prices to forecast subsequent cash prices leuthold and hartman martin and garcia indicates that the level of uncertainty about future price is high this coupled with livestock producers reticence to use the futures market as a hedging mechanism leuthold suggests that producers exposure to existing price risk may be prevalent this analysis quantitatively examines the importance of input and output price risk on aggregate sow farrowings first the price risk model is reviewed briefly then a conventional adaptive expectations model is used to develop price and risk variables alternative definitions of risk are assessed finally futures prices are used to generate expected price and risk variables

portfolio theory and the demand for futures the case of california cotton this paper examines the simultaneous choice of cropping patterns and futures positions it derives the demand for hedging as a function of the price of a hedge and the crop choice set it estimates these functions for california cotton farmers it finds that both the costs of hedging and the opportunity to diversify risk by growing other crops substantially change the optimal hedge for california cotton farmers

a model of the demand for investment banking advising and distribution services for new issues this paper presents a theory of the demand for investment banking advising and distribution services for the case in which the investment banker is better informed about the capital market than is the issuer and the issuer cannot observe the distribution effort expended by the banker the optimal contract under which the offer price decision is delegated to the better informed banker in order to deal with the adverse selection and moral hazard problems resulting from the informational asymmetry and the observability problem is characterized the model demonstrates a positive demand for investment banking advising and distribution services and provides an explanation of the underpricing of new issues an investment banker performs three functions which may be of value to an issuer of new securities underwriting advising and distribution this paper presents a theory of the demand for investment banking advising and distribution services based on an informational asymmetry between an issuer of new securities and an investment banker ultimately a theory of the organization of the financial intermediary industry is required that would predict which firms would use which types of financial intermediaries for which purposes and which firms would raise capital without engaging the services of a financial intermediary only a limited set of such predictions are developed here in the context of a model of a fixedprice offering under a negotiated contract in which the investment banker is

investigating the real situation of greek solar water heating market solar thermal applications have been acknowledged among the leading alternative solutions endeavouring to face the uncontrollable oil price variations the gradual depletion of fossil fuel reserves and the chain environmental consequences caused by its excessive usage almost 30 years after the initial emergence of the commercial domestic solar water heating system dswhs in the european market the corresponding technology is qualified as quite mature on top of this the european commission expects that 100 000 000 m2 of solar collectors are to be installed in europe by the year 2010 to facilitate durable and environment friendly heat in this context the greek dswhss market is highly developed worldwide having a great experience in this major energy market segment the present study is devoted to an extensive evaluation of the local dswhss market including a discerning analysis of its time variation taking seriously into account the corresponding annual replacement rate accordingly the crucial techno economic reasons limiting the dswhss penetration in the local heat production market are summarized and elaborated subsequently the national policy measures aiming to support the dswhss in the course of time are cited in comparison with those applied in other european countries next the financial attractiveness of a dswhs for greek citizens is examined in the local socio economic environment the present work is integrated by reciting the prospects and mustering certain proposals that if applied could stimulate the local market as a general comment the outlook for penetration of new dswhss in the local market is rather grim as the current techno economic situation of solar heat cannot compete with oil and natural gas heat production unless the remarkable social and environmental benefits of solar energy are seriously considered hence the greek state lacks stimulus to further dswhss installations being strongly in support of the imported natural gas as a result the future of domestic solar thermal market and the survival possibilities of the local manufacturers are at stake

a reformulation of the portfolio model of hedging comment in a recent article stewart l brown finds that hedge ratios estimated using percentage price change data are not significantly different from one while hedge ratios estimated using price level data are he argues that a the use of percentage price change data which he calls returns is more appropriate and b his empirical results do not support the portfolio theory of hedging many objective functions do indeed suggest the use of price change data although not necessarily percentage price change data instead of price level data when estimating hedge ratios and brown gives no new reasons for their use however brown s conclusion that hedge ratios significantly less than one support the portfolio theory while ratios not significantly different from one do not is erroneous moreover his paper misrepresents previous research on this topic my comment is intended to clarify these two issues

the relation between forward prices and futures prices abstract this paper consolidates the results of some recent work on the relation between forward prices and futures prices it develops a number of propositions characterizing the two prices these propositions contain several testable implications about the difference between forward and futures prices many of the propositions show that equilibrium forward and futures prices are equal to the values of particular assets even though they are not in themselves asset prices the paper then illustrates these results in the context of two valuation models and discusses the effects of taxes and other institutional factors

railroad rate deregulation and uncertainly of farm level prices for corn uncertainty of country elevator prices for corn in terms of error variance and mean squared forecast errors failed to increase in response to the deregulation in 1980 of railroad rates regression analysis was used to separate the uncertainty impacts of deregulation from those of other unanticipated changes in supply and demand factors influencing uncertainty included unexpected changes in storage costs export demand corn futures and rail car utilization some of the factors creating price uncertainty prior to deregulation were replaced by new uncertainty factors occurring as a result of deregulation

economic behavior under uncertainty a joint analysis of risk preferences and technology a method is developed to estimate jointly risk preferences and technology under general conditions the approach is illustrated in an application to the analysis of u s corn soybean acreage decisions over time the results provide useful information on the nature of farmers risk preferences and on the influence of price risk and production risk on acreage allocation and farmers welfare copyright 1996 by mit press

intertemporal commodity futures hedging and the production decision this paper deals with the producer s optimal use of commodity futures in hedging the framework for analysis is an intertemporal consumption and investment model the producer makes his production decisions at the beginning of the period and realizes his return at the end of the time interval during the period he faces both price and output uncertainties in applying stochastic dynamic programming methods this paper shows the effect of these risks on his consumption behavior further the paper investigates his optimal hedging positions in the futures market over time and his optimal production decisions finally implications of these results on the futures markets are discussed this paper studies a normative model of the farmer s optimal hedging strategy and consumption behavior in a continuous time framework recent papers for example berck 3 rolfo 18 stoll 21 have analyzed the farmer s hedging strategies in a one period context these papers have provided interesting insights into the farmer s production decisions and the optimal design of futures contracts and markets however in a one period model some rather restrictive conditions are imposed on the individual s behavior for example in these models an individual is assumed to ignore any information arrival process as a result the individual is assumed to adjust neither consumption behavior nor hedging positions to the changing state of the world during the production period these conditions can be relaxed in a continuous time framework in an intertemporal context the farmer s hedging problem may be viewed as follows since the farm income at harvest depends on both the spot price and the output in bushels the farmer is subject to both price and output uncertainties during the production period 1 when the farmer can hedge only in the commodity futures market he cannot eliminate both the price and output uncertainties by any hedging strategy 2 as the farm income represents a significant portion of his wealth he must necessarily hold an undiversified portfolio during the production period therefore in essence the farmer must solve for his investment consumption behavior and his hedging strategy facing the nonmarketable asset problem mayers 14 in a multiperiod framework in this context one can see intuitively the major difference between a one

basis risk measurement and analysis of basis fluctuations for selected livestock markets unanticipated basis changes can reduce the ability of futures markets to transfer risk and can affect income levels of producers and market participants this study examines short term basis risk defined as the variance of the random component of the basis over time for several midwest livestock markets basis risk is related to several factors influencing the long term pattern in the time series and unexpected changes in price little evidence is found that basis risk changed as maturity approached or that risk varied across markets except for the interior iowa hog market

equity issue specific versus broad regulatory protections against expropriation risk international evidence from seos abstract we compare non issue specific broad investor protections against expropriation by firm s insiders with regulations that specifically protect investors of new equity issues issue specific since in nation regulations rarely change and are homogenous for all firms it is difficult to compare issue and non issue specific investor protection mechanisms in country specific studies we utilize cross country differences in regulations to study the relative importance of issue specific and broad regulatory protections using data on seasoned equity offerings seo we find that seo underpricing is related to broad protections in particular seo underpricing is negatively positively related with the strength of ex post ex ante anti self dealing laws independent of broad protections seo underpricing is unaffected by issue specific investor protections that is neither by disclosure requirements imposed on equity issuers nor by equity issue specific liability rights conferred on investors interactions between broad protections and issue specific protections indicate issue specific protections reduce seo underpricing only in countries with strong broad protections

venture capitalist certification in initial public offerings this paper provides support for the certification role of venture capitalists in initial public offerings consistent with the certification hypothesis a comparison of venture capital backed ipos with a control sample of nonventure capital backed ipos from 1983 through 1987 matched as closely as possible by industry and offering size indicates that venture capital backing results in significantly lower initial returns and gross spreads in effect the presence of venture capitalists in the issuing firms serves to lower the total costs of going public and to maximize the net proceeds to the offering firm in addition we document that venture capitalists retain a significant portion of their holdings in the firm after the ipo the ability of third party specialists to certify the value of securities issued by relatively unknown firms in capital markets that are characterized by asymmetric information between corporate insiders and public investors has attracted much academic interest in recent years several authors including james 1990 blackwell marr and spivey 1990 and barry muscarella peavy and vetsuypens 1991 have developed and tested models based at least in part on the formal certification hypothesis presented in booth and smith 1986 a related body of work represented by deangelo 1981 beatty and ritter 1986 titman and trueman 1986 johnson and miller 1988 carter 1990 simon 1990 and carter and manaster 1990 has examined how investment bankers and auditors help resolve the asymmetric information inherent in the initial public offering ipo process in this paper we examine whether the presence of venture capitalists as investors in a firm going public can certify that the offering price of the issue reflects all available and relevant inside information we hypothesize that venture capitalists can perform this function that it will be an economically

fixed rate loan commitments take down risk and the dynamics of hedging with futures this paper develops a normative model to analyze the hedging and fee pricing decisions of a financial institution supplying fixed rate loan commitments to its customers in supplying fixed rate loan commitments the financial institution hereafter referred to as bank is assumed to act as an agent that transforms commitment risk through the use of financial futures contracts while most pre vious loan commitment models have analyzed the interest rate or price risk the bank faces in supplying fixed rate loan commitments they either have ignored or assumed away the loan take down or quantity risk l in general by making a formal fixed rate loan commitment the bank exposes itself to both a price and a quantity risk specifically a formal loan com mitment prespecifies the maximum size of the loan the purpose of the loan of ten project specific as well as the interest rate and fee to be paid by the borrower 14 15 however while a formal loan commitment imposes a contractual re quirement on the bank to supply funds up to a maximum amount at an agreed rate of interest the expected size of the loan to be taken down is often uncertain the reason is that for project specific lines of credit the amount taken down will depend on the future state s of the world that are revealed to the borrower at the end of the commitment period as well as on the limitations and constraints im posed on the use of funds in the loan commitment contract for example construction delays and other market imperfections that hamper a planned invest

investment and hedging under a stochastic yield curve abstract this paper examines portfolio decisions involving both fixed and non fixed income securities two state variables the short term and the long term interest rates fully determine the bonds prices and partly influence the other assets prices we propose first a methodology for determining optimal portfolios in such a context and then use that methodology to solve the portfolio problem of investors whose long term bond holdings are constrained which generates undesirable interest rate risk that are hedged with futures contracts the individual futures positions which involve several hedging components and the futures market equilibrium open interest are derived and analysed

production flexibility stochastic separation hedging and futures prices we study a dynamic model where uncertainty about interim output adjustments causes producers to face price cost and output uncertainty stochastically separable production decisions are independent of the producer s risk preferences and expectations and are based on the prevailing futures price as a certain output price conditions under which futures contracts achieve stochastic separation are established optimal hedging and maturity structure of futures contracts equilibrium futures prices and the effects of futures trading on output are studied the systematic risk premium depends on the product of the futures beta and the covariance of the market return with production revenues article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

performance of utility based hedges abstract hedgers as investors are concerned with both risk and return however when measuring hedging performance the role of returns and investor risk aversion has generally been neglected in the literature by its focus on minimum variance hedging in this paper we address this by using utility based performance metrics to evaluate the hedging effectiveness of utility based hedges for hedgers with both moderate and high risk aversion together with the more traditional minimum variance approach to examine this for an energy hedger we apply our approach to wti crude oil for three different hedging horizons daily weekly and monthly we find significant differences between the minimum variance and utility based hedging strategies in sample for all frequencies however performance differentials between the different strategies are small and not economically significant out of sample results support these findings across all frequencies
