are biofuels a feasible option abstract recently a number of objections have been raised against the use of ethanol produced from agricultural products such as maize sugarcane wheat or sugar beets as a replacement for gasoline despite some of their advantages such as being cleaner and to some extent renewable we address these objections in this paper topics discussed include the corn connection which was theorized to be a cause of deforestation in the amazonia the rise of food prices due to ethanol production and the real possibilities of ethanol in reducing greenhouse gas emissions it has been shown that such concerns are grossly exaggerated and that ethanol from sugarcane as produced in brazil is the preferred option for the production of fuel not only in terms of cost but also as a favourable energy balance finally the possibility of expanding ethanol production to other sugar producing countries is also discussed

biofuels what a biopact between north and south could achieve abstract with very few exceptions such as the recent remarks by international energy agency iea head claude mandil commentators on the world s energy issues have yet to recognize the enormous contribution that biofuels producers from the south could make to solving the world s greenhouse gas emission problems and problems to do with the peaking of oil supplies once the equation between biofuels and high cost land intensive cultivation in the north is broken and a quite different scenario involving production in the south is adopted then the possibilities are dramatically changed the argument of this paper is that a transition to substitution of 20 percent of oecd gasoline needs by 2020 could be met from the south by creating the equivalent of 18 brazils over the course of the next decade such an enormous transition will not occur by itself or through the operation of market forces alone it needs an institutional framework one that guarantees for the countries of the north regular supplies of biofuels produced in a responsible manner and guarantees for the countries of the south open markets for the biofuels produced the oecd is in the best position to bring about such an arrangement through taking the initiative of offering developing countries a biopact between north and south thereby creating for the first time a global market for biofuels the launch of an international biofuels forum under the auspices of the un in early 2007 is a step towards the creation of such an international framework where north south issues on biofuels may be fruitfully addressed

does the bond market predict bankruptcy settlements this study shows the extent to which deviations from the absolute priority rule increase or decrease the bankruptcy emergence payoff to traded i e usually junior claimants bondholders the data indicate that on average bondholders benefit albeit slightly from absolute priority rule apr violations this paper also examines the degree to which the bond market in the bankruptcy filing month anticipates departures from the apr and other influences on the payoff to bondholders in other words we investigate the informational efficiency of the market for bankrupt bonds overall despite the complex and lengthy nature of bankruptcy proceedings the results support efficiency the finance literature has traditionally assumed that when a firm enters bankruptcy the creditors become the owners and the value of the firm is distributed according to the absolute priority rule apr the apr states that senior creditors should be fully compensated before junior creditors receive any portion of the bankrupt firm s value and junior creditors should receive full payment before shareholders receive any compensation in practice formal bankruptcy proceedings are complex processes that often violate the apr brown 1989 captures some of the intricacies of this process in a game theoretic model showing that the solution to the bargaining process in bankruptcy can involve deviations from the apr although the solution

credit risk measurement developments over the last 20 years abstract this paper traces developments in the credit risk measurement literature over the last 20 years the paper is essentially divided into two parts in the first part the evolution of the literature on the credit risk measurement of individual loans and portfolios of loans is traced by way of reference to articles appearing in relevant issues of the journal of banking and finance and other publications in the second part a new approach built around a mortality risk framework to measuring the risk and returns on loans and bonds is presented this model is shown to offer some promise in analyzing the risk return structures of portfolios of credit risk exposed debt instruments

drexel burnham lambert s bankruptcy and the subsequent decline in underwriter fees abstract in the 1980s drexel burnham lambert dominated the underwriting of junk bonds with close to a 50 market share in 1990 drexel went bankrupt and was liquidated and the percentage underwriting fees for junk bonds subsequently dropped dramatically we present strong evidence that the exit of drexel burnham lambert and the resulting increase in competition for market share were major contributing factors to the decline in junk bond underwriter fees

pricing credit derivatives with rating transitions we present a model for pricing risky debt and valuing credit derivatives that is easily calibrated to existing variables our approach expands a classical term structure model to allow for multiple rating classes of debt the framework has two salient features 1 it uses a rating transition matrix as the driver for the default process and 2 the entire set of rating categories is calibrated jointly which allows arbitrage free restrictions across rating classes as a bond migrates among them we illustrate the approach by applying it to price credit sensitive notes that have coupon payments linked to the rating of the underlying credit

evaluating prior beliefs in a demand system the case of meat demand in canada an almost ideal demand system for meats is estimated using canadian data a bayesian approach is used to impose inequality restrictions on substitution elasticities via monte carlo integration and importance sampling in order to conform with prior beliefs about curvature and monotonicity restrictions and substitution relationships results are more consistent with the concavity and monotonicity restrictions from demand theory than with the added restriction that all meats are substitutes

a class of differential demand systems abstract the rotterdam almost ideal demand system cbs and nbr models constitute a class of differential demand systems they correspond to alternative assumptions made concerning the constancy of certain parameters this paper discusses the restrictions that they impose on the evolution of demand elasticities over time

perceptions and the politics of finance junk bonds and the regulatory seizure of first capital life in may 1991 one month after seizing executive life california regulators seized first capital life fclic both insurers were drexel clients with large junk bond holdings and both had experienced bank runs fclic s run followed regulators televised comments that its poor condition necessitated a substantial cash infusion yet fclic s statutory capital with junk bonds real estate and mortgages marked to market was far from lowest among major insurers with california policyholders it becomes lowest if junk bonds alone are marked to market at year end 1990 ignoring larger market declines in real estate mortgages and the junk bond market s 21 return in early 1991 our findings suggest a regulatory bias against junk bonds in the political backlash against the 1980s

an empirical investigation of u s firms in reorganization the purpose of this paper is to understand the institutional features of chapter 11 from an empirical examination of thirty firms that have emerged from reorganization we find the recontracting framework of chapter 11 to be complex lengthy and costly violations of absolute priority in favor of stockholders are frequently encountered these deviations may result from the bargaining process of chapter 11 or from a recontracting process between creditors and stockholders which recognizes the ability of stockholder oriented management to preserve firm value an example of such recontracting addresses myers underinvestment problem an investigation of the effects of chapter 11 on the pricing of risky debt is also provided the purpose of this paper is to understand the institutional features of chapter

revisiting aggregate u s meat demand with a bayesian averaging of classical estimates approach do we need a more general theory although meat demand is one of the most studied issues in agricultural economics our understanding of this phenomenon has been hampered by valid concerns about model specification uncertainty this article revisits the need for more general theories of aggregate u s meat demand using a bayesian averaging of classical estimates approach we draw comprehensive inferences over 1 048 576 demand systems we find very little evidence supporting the need for more general theories that include demand determinants beyond prices and expenditures we find strong evidence in support of symmetry and negativity but strong evidence against homogeneity which is consistent with other research copyright 2008 oxford university press

maintaining and testing separability in demand systems we derive a general elasticity representation of the necessary and sufficient conditions for direct weak separability of the utility function parametric restrictions required to implement the separability conditions are presented for three common demand systems the almost ideal translog and rotterdam our empirical application uses the rotterdam model to test a few separable structures within a complete u s demand system emphasizing food commodities results based on size corrected likelihood ratio tests provide support for commonly used separability assumptions about food and meat demand

estimating structural change with smooth transition regressions an application to meat demand this paper explores the role of structural change in systems of demand equations specifically we adapt the time varying regression framework of lin and terasvirta 1994 which in turn is related to the dynamic smooth transition models introduced by terasvirta 1994 unlike previous efforts at modeling structural change in demand systems we do not impose the nature of the change to be monotonic several non monotonic alternatives are considered an application is presented using the almost ideal inverse demand system iaids applied to u s meat demand data 1960 2004 results show the importance of modeling structural change and that moreover the best fitting model is associated with a form of symmetric non monotonic structural change

liquidation costs and capital structure abstract we investigate the relation between liquidation costs of assets and composition of capital structure for firms that reorganized under chapter 11 of the bankruptcy code firms with high liquidation costs emerge from chapter 11 with relatively low debt ratios the debt of these firms is more likely to be public and unsecured and to have less restrictive covenant terms these firms are also more likely to raise new equity capital assets with high liquidation costs thus lead firms to choose capital structures that make financial distress less likely

the producer welfare effects of trade liberalization when goods are perishable and habit forming the case of asparagus asparagus is a perishable highly seasonal crop we find that out of season imports of asparagus caused habit formation that increased demand in the u s growing seasons we find that habit effects offset about 64 of the welfare losses to u s asparagus producers from increased mexican imports under nafta and all of the u s producer welfare losses from increased peruvian imports under the andean trade preference act we estimate that the u s producer welfare losses from nafta are less than the annualized value of market loss assistance provided them in the 2008 farm bill jel classifications d12 f130 q17 q18

corporate credit risk dynamics the lack of widely available and comprehensive data of default activity on the corporate level has encouraged the advance of theories of corporate credit risk far beyond related empirical work this article addresses this deficit by examining a unique data set corporate bond defaults and credit ratings compiled by moody s investors service since 1920 the article investigates the time inhomogeneity of company default risk that is the pattern in which the risk of default for a company changes over time the empirical analysis addresses company default risk within a regression framework of competing risks or hazards the analysis identifies and quantifies variations in default risk with macroeconomic conditions with industries and through time an important characterization for many approaches to measuring and managing credit risk

how biofuel policies backfire misguided goals inefficient mechanisms and political ecological blind spots abstract the development of an economically viable biofuel industry rests on strong state subsidies for production and processing creation of markets through government procurement fuel blending mandates price controls as well as foreign trade tariffs and quotas and multiple interventions in agricultural ecological and other regulations we use an approach grounded in agrarian political economy to critically analyze the literature on how biofuel policies interact with broader production trade and agro ecological processes we focus on policies involving the most prominent crops in the places where biofuel production has advanced the most i e usa brazil and the eu but also extend analysis to their relations with broader transformations in production commercial and even governance practices around the world we investigate the political and economic interests driving biofuel policies and how these set the terms in which state interventions and policies are conceived and implemented we find that these are not developed and implemented according to environmental or inclusive pro poor development purposes but according to state interests in energy security and its intersection with a tense alliance between corporate sectors rendering many policy mechanisms ineffective or even outright counterproductive to effectively facilitate more socially and environmentally sustainable energy production and agricultural practices

high yield bond default and call risks this paper empirically investigates high yield bond default and call behavior using a competing risks hazard model that simultaneously estimates the impact of bond age issue specific characteristics and business conditions on both events results reveal nonmonotonic aging effects default rates increase and then drop while call rates first increase and then level off rating and coupon size affect default risk while maturity and issue size impact only call rates defaults are more likely when economic conditions have worsened and no improvement is anticipated calls are more likely when interest rates have decreased but are expected to rise

demand for beef and chicken products separability and structural change several studies have indicated that the recent shift from beef to poultry in consumption is not entirely caused by changes in rela tive prices or income braschler chavas dahlgran hudson and vertin moschini and meilke frank thurman most studies of structural change have focused on red meat consumption only thurman has looked closely at the poultry market and no one has considered poultry products yet the mix of chicken products marketed changed dramat ically during the last twenty years and should have influenced aggregate meat demand the share of broiler slaughter marketed as whole birds declined from 74 in 1965 to 28 in 1985 while cut up parts and processed chick en products increased from 26 to 72 whole birds are inferior goods and cut up parts and processed chicken are normal goods haidacher et al the shift in chicken prod uct mix away from whole birds should have increased the preference for total chicken in this article two related questions are ad dressed first do consumers allocate expendi tures among meats by animal origin or by product type second does disaggregation of meat into products in a meat demand model give insight into the causes of structural

empirical modelling of the aggregation error in the representative consumer model this paper examines different approaches to modelling the aggregation error associated with the representative consumer model each approach is based on an analytical framework intended for modelling aggregate time series data on quantities and prices with potential additional measures of income distribution simple functions that track aggregation error over time are found to perform better than more complex and theoretically sophisticated models an explanation is given based on typical time series characteristics of economic data

the design of bank loan contracts the unique characteristics of bank loans emerge endogenously to enhance efficiency in a model of renegotiation between a borrower and a lender in which there is the potential for moral hazard on each side of the relationship firm risk is endogenous and renegotiated interest rates on the debt need not be monotone in firm risk the initial terms of the debt are not set to price default risk but rather are set to efficiently balance bargaining power in later renegotiation loan pricing may be nonlinear involving initial transfers either from the borrower to the bank or front the bank to the borrower article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

determinants of the decreasing term structure of relative yield spreads for taxable and tax exempt bonds the empirical finding that the relative yield spread for taxable and tax exempt bonds decreases across the term structure is usually attributed to tax differentials and or arbitrage opportunities using monthly data it is found that the decresing term structure of relative yield spreads is determined by the decreasing forward marginal tax rate increasing default risk premium increasing tax timing option premium and expected rate of inflation

original issue high yield bonds aging analyses of defaults exchanges and calls this paper presents an aging analysis of 741 high yield bonds and finds default exchange and call percentages substantially higher than reported in earlier studies by december 31 1988 cumulative defaults are 34 percent for bonds issued in 1977 and 1978 and range from 19 to 27 percent for issue years 1979 1983 and from 3 to 9 percent for issue years 1984 1986 exchanges are also a significant factor although they often are followed by default moreover a significant percentage of high yield debt 26 47 percent for 1977 1982 has been called by december 31 1988 approximately one third of the bonds issued in 1977 1982 has defaulted or been exchanged and an additional one third had been called on average only 28 percent of these issues are still outstanding there is no evidence that early results for more recent issue years differ markedly from issue years 1977 to 1982

final and b molasses for fuel ethanol production and some market implications some concern about biofuels has been expressed because the growing demand for biofuels could cause among other potential impacts farming lands to be used for producing biofuel instead of food thus raising food prices such concern is also present when considering the relationship between sugar and fuel ethanol production the sugar market is characterized by a low growth rate of demand volatile prices widespread interventions and recently an increasing surplus production in parallel an emerging world market for fuel ethanol has expanded by 12 annually due to policy support some countries have mandated ethanol gasoline blends while others are looking for ways to introduce them or expand the existing market the aim of this work is to assess the potential in the short term for fuel ethanol production by using intermediate molasses in countries that industrialize sugarcane the following main sugarcane producing countries were taken as example colombia guatemala mexico australia india and thailand the result of this research shows that those countries could together produce an amount equal to approximately 16 5 of the fuel ethanol produced worldwide in 2015 in addition four countries could replace more than 10 of their national gasoline consumption with ethanol produced from a molasses this work however suggest producing fuel ethanol by using final molasses and 20 of b molasses that option would cause a 3 average reduction in sugar production but this decline is nonetheless equivalent to the average growth rate of the global sugar surplus in the last three years moreover the suggested scheme showed a favorable opportunity cost in comparison with the exclusive production of sugar the proposed type of ethanol production could support the development of national ethanol markets in the short term while more sustainable options e g ethanol from residual lignocellulosic materials are not available

forecasting losses on a liquidating long term loan portfolio abstract assessing the condition of financial institutions and valuation of loan portfolios in secondary markets require the estimation of exposure to losses on existing portfolios of long term loans data from a major u s financial institution were used to construct a forecasting model with markovian structure and nonstationary transition probabilities the model proved to be effective in representing changes in probability of default that occur as individual loans mature and accurate in forecasting aggregate defaults and losses on a nationwide portfolio of long term loans

term structure effects on default risk premia and the relationship of default risky tax exempt yields to risk free taxable yields a note abstract the behavior of the default risk premium on bonds has caught the attention of many researchers some researchers have analyzed how default risk premia may vary with maturity it has been suggested that default risk premia are independent of maturity however recent research by rodriguez 1988 shows this to not hold for nonpar taxable bonds this research shows that the shape of the underlying term structure affects default risk premia for even par bonds in a systematic way furthermore the maturity dependent variation in equilibrium tax rates has a strong impact upon default risk premia behavior where equilibrium tax rates are derived from comparisons of taxable and tax exempt bonds the inclusion of the shape of the underlying term structure also has very important implications for the relation between taxexempt yields and taxable yields the slope and intercept terms of the relation between taxexempt and taxable yields are clearly dependent upon maturity a fact which has not been recognized before

the evolution of buyout pricing and financial structure in the 1980s we examine changes in the pricing and financial structure of large management buyouts in the 1980s over time 1 buyout price to cash flow ratios rose in absolute terms particularly in deals financed using public junk bonds 2 required bank principal repayments accelerated leading to sharply lower ratios of cash flow to total debt obligations 3 private subordinated and bank debt were replaced by public junk debt and 4 management teams and dealmakers took more money out of transactions up front these patterns are consistent with an overheating phenomenon in the buyout market preliminary post buyout evidence lends some support to this interpretation

corporate compliance with debt covenants in this paper i present and test a model of corporate compliance with the debt covenant requiring payment of a current obligation this study adds to the empirical literature on forecasting financial distress by showing conditions under which debt default may be a rational economic decision by the firm s shareholders this analysis departs from empirical financial distress studies which are often not linked to an underlying economic theory the focus on covenant default also extends the literature which has modeled bankruptcy bulow and shoven 1978 and liquidation decisions titman 1984 but which has not considered a common first symptom of financial distress covenant default briefly the model examines the costs that influence shareholders decision to comply with or violate a particular debt covenant payment of a current obligation these costs include those associated with bondholders reaction to possible default the model predicts that shareholders will default when holding other factors constant i interest rates have declined relative to coupon rates stated in the debt issue ii the probability of paying future obligations is high and iii the cost of obtaining funds to pay the obligation is high the model also predicts when stockholders and bondholders will renegotiate the debt contract and the amount of wealth transferred in the renegotiation finally the

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

a discounted cash flow model of convertibles subject to multiple calls in a world of refunding costs and stochastic interest rates fixed income securities which can be converted into other assets such as common stock represent a sizable portion of the capital market 33 and have therefore received frequent attention in the financial literature 20 21 23 35 39 however due to their complexity attempts to develop mathematical models of convertibles have encountered severe computational and theoretical difficulties 36 one of the primary complications results from convertible securities generally having contractual call features which permit the issuing organization to redeem the securities at stipulated dates for specific prices in addition although a majority of convertibles listed in moody s bond guide have sinking funds the issue of analyzing convertible sinking fund calls represents a specific problem that has never been adequately addressed early studies of convertibles such as brigham 10 focused on the discounted cash flow approach to valuing the securities the general procedure was to estimate a terminal price for the convertible on an arbitrarily specified date in the future and then take the present value of the price together with all intervening fixed income payments these models lacked precision insofar as no theoretical framework was developed for specifying the relevant terminal date terminal price or discount rate and the individual effect of each call feature on convertible values was largely ignored other research such as walter and que 38 has employed regression analysis to pro

the role of theoretical restrictions in forecasting with inverse demand models in recent years the theoretical restrictions of consumer demand have been examined in post sample forecasting exercises however this work has uniformly ignored the concavity restrictions of consumer demand in this paper we evaluate a series of normalized quadratic inverse demand system nqids specifications using rolling windows and generating one to four step ahead forecasts to estimate the models eleven categories of south atlantic fish are used from 1980 through 2001 in addition to the nqids we also examine the forecasting performance of a purely time series model we find that the best predictions are achieved using a composite forecast

the dynamic responses of crop and livestock prices to money supply shocks a bayesian analysis using long run identifying restrictions the impact of monetary policy on agriculture has been much debated this study examines the dynamic responses of u s agricultural prices to money supply shocks using three innovations first the variables responses are identified by long run money neutrality restrictions instead of the more common contemporaneous ordering second a bayesian approach to model uncertainty is used to add robustness to the estimation process third agricultural prices are disaggregated into crop and livestock components the empirical results find that both agricultural sectors benefit in the short run from positive money supply shocks with agricultural prices increasing relative to the general price level

the long term default performance of bank underwritten security issues abstract the glass steagall act of 1933 barred commercial banks and their affiliates from underwriting and dealing in securities activities amidst concerns that banks abused the trust of their depositors and clientele by systematically underwriting poor quality security issues this paper examines if these concerns were justified by studying the long term default performance of bank underwritten issues as compared to non bank underwritten issues the evidence shows that contrary to conventional wisdom bank underwritten issues defaulted less than non bank underwritten issues over a seven year period from the issue date and had a significantly lower mortality rate

the default rate experience on high yield corporate debt recent 1978 83 net returns on high yield low rated debt have been impressive averaging 490 to 580 basis points above the long term government bond index but low rated junk bonds pose a risk of default not present in the higher rated segment of the bond market the authors divided the par value of defaulting debt by total low rated straight debt outstanding to arrive at an estimate of the default rate for high yield bonds excluding johns manville which had the only defaulting debt rated investment grade just prior to the default date for the 1974 84 period this averaged 1 52 per cent or 152 basis points annually year to year variations in the rate were substantial furthermore default experience differed across various industry segments railroads and reits were particularly vulnerable to default in the past although they are unlikely to represent a large portion of future defaults retailer electronic computer airline and oil and gas defaults have become more common in recent years losses from default are actually lower than the default rate alone implies defaulted bonds traded on average at 41 per cent of par shortly after default after accounting for the bonds retained value and the loss of interest the average reduction in return to the investor who had purchased the bonds at par would have been in the range of 96 to 100 basis points annually

sugar rush prospects for a global ethanol market in 2005 the major economies of the world including the g8 and 5 developing nations mexico india brazil china and south africa along with the united nations the international energy agency and the european union launched the global bioenergy partnership to discuss ways to promote the sustained use and production of biofuels around the globe reflecting growing concerns for finding economically viable substitutes for petroleum this paper examines whether and if a vibrant global market in biofuels based on sugarcane based ethanol is economically feasible the paper finds that while there is already international trading in biofuels it is highly limited compared with its potential in the current climate of accelerating fossil fuel prices biofuels represent an increasingly attractive displacement for some of our fossil fuel addiction not only do they substitute for petrol but they also produce lower emissions the paper finds that sugarcane ethanol could make an important contribution to substituting for a portion of petroleum and also offer potential benefits for international development

the intersection of market and credit risk abstract economic theory tells us that market and credit risks are intrinsically related to each other and not separable we describe the two main approaches to pricing credit risky instruments the structural approach and the reduced form approach it is argued that the standard approaches to credit risk management creditmetrics creditrisk and kmv are of limited value when applied to portfolios of interest rate sensitive instruments and in measuring market and credit risk empirically returns on high yield bonds have a higher correlation with equity index returns and a lower correlation with treasury bond index returns than do low yield bonds also macro economic variables appear to influence the aggregate rate of business failures the creditmetrics creditrisk and kmv methodologies cannot reproduce these empirical observations given their constant interest rate assumption however we can incorporate these empirical observations into the reduced form of jarrow and turnbull 1995b drawing the analogy risk 5 63 70 model here default probabilities are correlated due to their dependence on common economic factors default risk and recovery rate uncertainty may not be the sole determinants of the credit spread we show how to incorporate a convenience yield as one of the determinants of the credit spread for credit risk management the time horizon is typically one year or longer this has two important implications since the standard approximations do not apply over a one year horizon first we must use pricing models for risk management some practitioners have taken a different approach than academics in the pricing of credit risky bonds in the event of default a bond holder is legally entitled to accrued interest plus principal we discuss the implications of this fact for pricing second it is necessary to keep track of two probability measures the martingale probability for pricing and the natural probability for value at risk we discuss the benefits of keeping track of these two measures

model choice in consumer analysis taiwan 1970 89 expenditure data were used to study how income and prices influenced consumer demand in taiwan during the last decade alternative differential demand models combining the features of the rotterdam model and the almost ideal demand system aids were tested aids type demand responses describe taiwanese consumer behavior better than do the other specifications

the effects of male and female labor supply on commodity demands we examine the effects of male and female labor supply on household demands and present a simple and robust test for the separability of commodity demands from labor supply using data on individual households from six years of the uk fes we estimate a demand system for seven goods which includes hours and participation dummies as conditioning variables allowance is made for the possible endogeneity of these conditioning labor supply variables we find that separability is rejected furthermore we present evidence that ignoring the effects of labor supply leads to bias in the parameter estimates

the resiliency of the high yield bond market the ltv default this paper investigates the resiliency of the new issue high yield bond market by examining the changes in implied default rates of such bonds before and after the largest high yield bond default i e the ltv bankruptcy specifically the paper compares implied default probabilities of high yield bonds during the post ltv period calculated from actual new issue yields with instrumental default probabilities calculated on the assumption that the default had not occurred a comparison of these probabilities reveals that the market s perception of default on the hjgh risk segment of the bond market increased significantly after the ltv bankruptcy however the effect was transitory lasting only six months thus the market was resilient to a major default in recent years high yield debt has become a significant segment of the corporate bond market the main source of the growth has come from new issues of high yield corporate bonds rather than an increase in fallen angels 1 the driving force behind this new breed of high yield debt growth has been its use as a means to tap the capital markets to finance increasingly common leveraged buyouts hostile takeovers and major corporate restructurings the market acceptance of high yield bonds was further enhanced by empirical evidence that net returns on a diversified portfolio of low grade bonds exceeded those on highgrade bonds while the volatility of their monthly returns was no greater 2 the frenzied pace of growth in the high yield debt market however has been accompanied by increasing concerns from various quarters 3 critics have char

the logic of testing structural change in meat demand a methodological analysis and appraisal in the past two decades the profession has expended valuable resources testing structural change in meat demand with mixed results overlooked to date is a fundamental methodological problem that transcends all methods of testing for structural change in this study a methodological framework is used to show that there is no valid test of structural change because of this result additional criteria from the methodology literature are used to evaluate the literature on structural change in meat demand and to provide suggestions for fertile areas of future research

a non gaussian panel time series model for estimating and decomposing default risk we model 1981 2005 quarterly default frequencies for a panel of u s firms in different rating and age classes from the standard and poor database the data are decomposed into systematic and firm specific risk components where the systematic component reflects the general economic conditions and the default climate we need to cope with the shared exposure of each age cohort industry and rating class to the same systematic risk factor strongly non gaussian features of the individual time series possible dynamics of an unobserved common risk factor changing default probabilities over the age of the rating and missing observations we propose a non gaussian multivariate state space model that deals with all of these issues simultaneously the model is estimated using importance sampling techniques that have been modified to a multivariate setting we show in a simulation study that such a multivariate approach improves the performance of the importance sampler in our empirical work we find that s

lower grade bonds their risks and returns to reflect as realistically as possible the risks and returns of lower grade bonds the authors constructed an index from actual average returns used in the compilation of the salomon brothers and drexel burnham lambert lower grade indexes supplementing these with month end prices prior to 1982 from the sp thus a diversified portfolio may contain both the debt and equity of the issuing companies

security pricing and deviations from the absolute priority rule in bankruptcy proceedings claims ultimately awarded to shareholders of firms in reorganization were examined for a sample of 30 filings under the 1978 bankruptcy reform act we measured the amount paid to shareholders in excess of that which they would have received under the absolute priority rule and found that this amount represents on average 7 6 of the total awarded to all claimants evidence is also reported that common share values reflect a significant proportion of value ultimately received in violation of absolute priority suggesting that deviations from the rule were expected by the equity markets the absolute priority rule hereafter apr states that a bankrupt firm s value is to be distributed to suppliers of capital such that senior creditors are fully satisfied before any distributions are made to junior creditors and junior creditors are paid in full before common shareholders bankruptcy reorganization proceedings however are leaving shareholders and junior creditors with valuable assets even when senior claimants receive only partial settlements as barrett and sullivan 1988 noted traditionally shareholders have been last in line their claims on a troubled company s assets have had the lowest priority and their impact on the course of bankruptcy code proceedings generally has been next to nil but lately the balance of power has been shifting warner 1977 provided one of the early discussions of the implications of deviations from the apr baldwin and mason 1983 pp 510 511 examined the resolution of claims in the massey ferguson reorganization and provided no support for the hypothesis that the market believes absolute priority rules will be enforced if the firm defaults on its financial obligations franks and torous 1989 analyzed a sample of bankruptcies that occurred during the period 1970 through 1984 and found that 21 of 27 sample cases exhibited departures from the apr more recently weiss 1990 examined 37 firms that filed for bankruptcy between 1980 and 1986 and reported that 27 of the cases involved apr violations

time varying return and risk in the corporate bond market this paper examines the pricing of exchange traded long term corporate bond portfolios observable instruments measuring the term structure of interest rates levels of bond and stock prices and a january dummy are found to predict excess returns on corporate bonds an intertemporal asset pricing model with changing expectations and unobservable factors is then estimated for the predictable excess returns using hansen s generalized method of moments the results show that a multibeta linear time varying model of con ditional expected returns with constant betas can successfully value corporate bonds spe cifically the tests indicate the presence of two time varying hedge portfolios the data however support a single latent variable specification when all january observations are excluded this result suggests the existence of a strong january seasonal in one of the latent variables

the significance and insignificance of demand analysis in evaluating promotion programs the estimated effects of promotion on demand are often small and insignificant yet the estimated effects of promotion on industry profit are often positive and large this puzzle is explained by demonstrating that in significance of promotion in a demand equation does not imply and is not implied by in significance of promotion in an industry profit equation a monte carlo example is provided the econometric modeling implications are discussed the short run marginal effect of a dollar of generic beef promotion on slaughter cattle industry profit is estimated to be about 9 84 with a standard error of 3 77 for 1997 the 1996 farm bill requires that check off based commodity promotion programs be evaluated at least once every five years this legislation has increased the interest in the effects of commodity promotion programs a

european union leadership in biofuels regulation europe as a normative power the rapid emergence of the european union eu as a leader in global environmental politics has led many scholars to argue in favour of the eu being a normative power in international relations this paper critically examines the eu s biofuels policy and evaluates whether its attempts to lead by example and shape international practice in this field could support such arguments europe s biofuel policies are evaluated through a sustainable development lens so as to determine the extent to which it has embraced a holistic approach to sustainability while not dismissing that the identity of the eu is indeed an explanatory factor and that normative intentions may well be regarded as a motivating force this study argues that an interest based perspective on international environmental regulation offers a supplementary view of how an actor s preferences for an international regime are shaped by erecting barriers aimed at shielding its own inefficient domestic biofuels production the eu is in essence placing trade competitiveness and economic growth above environmental protection thus permitting sustainability concerns to be addressed only in part

defaults of original issue high yield convertible bonds recent studies using aging analysis have found high rates of default for rated nonconvertible high yield bonds this paper examines the remainder of the market and concludes that rated and nonrated convertible high yield bonds had significantly lower default rates it also provides some evidence that nonrated nonconvertible securities may have lower default rates even after controlling for issue size and coupon rates in a logit model these differences remain statistically significant the success in marketing original issue high yield bonds has generated significant interest in their default experience studies comparing defaults to the par value of outstanding issues such as altman 1987 altman and nammacher 1985 and weinstein 1987 have found relatively low default rates however these studies understate default rates because of the rapid increase in the par value of outstanding issues and because cumulative default rates increase with years from issuance two recent studies by altman 1989 and asquith mullins and wolff 1989 have corrected these problems by using aging analysis to follow rated nonconvertible high yield bonds over time they find cumulative default rates for such bonds 10 years after issuance exceeding 30 percent this study extends the literature on high yield default rates to convertible and nonrated securities not examined in previous studies the high yield market can be partitioned into rated nonconvertible rated convertible nonrated nonconvertible and nonrated convertible securities other things equal one would expect higher default risk to be associated with higher yields however other things are not equal for example securities may have high yields because of differences in liquidity or differences in conversion options therefore yields reflect more than just expected default risk they also incorporate premiums for other characteristics of individual securities when the securities are partitioned by rating and convertibility the results of this paper show that the cumulative default rates are lower for rated convertible securities than for rated nonconvertible securities because in

the performance of bond mutual funds using linear and nonlinear models the authors examine two samples of bond funds one sample designed to eliminate survivorship bias and a second much larger sample overall and for subcategories of bond funds they find that bond funds underperform relevant indexes postexpenses the authors results are robust across a wide choice of models they find that on average a percentage point increase in expenses leads to a percentage point decrease in performance the nonlinear model weights closely match actual composition weights the authors find no evidence of predictability using past performance to predict future performance for their unbiased sample copyright 1993 by university of chicago press

the silence of the lambdas a test of the almost ideal and rotterdam models during the past decade the linear approximate la almost ideal demand system and the rotterdam model have been adopted by agricultural economists as the demand systems of choice in most applications the apparent explanation is that the two models are both second order locally flexible and compatible with demand theory they have identical data requirements and are equally parsimonious with respect to parameters and both are linear in the parameters while the two models are thus equally attractive in most respects and indeed appear very similar in structure they lead to different results in some applications this article develops a test of each against the other in an illustrative application to u s meat demand the almost ideal model is rejected while the rotterdam model is not
