attitudes toward risk and the risk return paradox prospect theory explanations this study attempted to explain bowman s risk return paradox in terms of recent research in behavioral decision theory and prospect theory the research emphasized the role of reference or target

taxes on tax exempt bonds implicit tax rates priced in the cross section of municipal bonds are approximately two to three times as high as statutory income tax rates with implicit tax rates close to 100 using retail trades and above 70 for interdealer trades these implied tax rates can be identified because a portion of secondary market municipal bond trades involves income taxes after valuing the tax payments market discount bonds which carry income tax liabilities trade at yields around 25 basis points higher than com parable municipal bonds not subject to any taxes the high sensitivities of municipal bond prices to tax rates can be traced to individual retail traders dominating dealers and other institutions the issue of how taxes affect asset prices is an important issue in finance accounting and economics in theoretical models examining the effect of taxes

a behavioral theory of r d expenditures and innovations evidence from shipbuilding i base an integrated model of innovation development and launch on the behavioral theory of the firm this model specifies that research and development expenses are increased when low performance causes problemistic search and when excess resources cause slack search innovations generated by search are launched if low performance gives managers high risk tolerance using data from shipbuilding firms i show that high performance reduces r d intensity and innovation launches and high slack increases r d intensity as predicted

strategic group formation and performance the case of the u s pharmaceutical industry 1963 1982 the focus of this paper is on three major questions 1 what is the theoretical rationale for the strategic group concept 2 does strategic group membership have performance implications and 3 are strategic groups and membership in strategic groups stable characteristics of industries a statistical procedure is proposed to longitudinally identify strategic groups the empirical setting is the u s pharmaceutical industry over the period 1963 82 while performance differences are found in terms of market share profitability differences between groups are not observed neither are differences found in terms of risk and risk adjusted performance these results are attributed to the existence of performance variation within each strategic group a dynamic model of competitive repositioning is proposed which helps integrate the findings from the study

exports and economic growth in bangladesh this study investigates the effect of exports on economic growth in bangladesh based on a two sector growth model using annual data for the period 1961 92 the article estimates an autoregressive conditional heteroscedastic model of economic growth which is found to capture the volatility of the bangladesh economy the results suggest that an increase in the share of investment in gdp significantly increases the growth rate of gdp in normal years but negligibly increases gdp growth in abnormal years abnormalities in the economy arise from war political turmoil and natural disasters the key finding is that export growth has significantly increased economic growth through its positive impact on total factor productivity in the economy the contribution of exports to economic growth was more pronounced during 1982 90 when the government pursued a policy of trade liberalisation and structural reform and political turmoil was not persistent this finding is not sensitive to the choice of the model or t

political uncertainty and public financing costs evidence from u s gubernatorial elections and municipal bond markets this research investigates how political uncertainty around u s gubernatorial elections in uences the borrowing costs of public debt measured by yields of municipal bonds our evidence from both the new issuance market and the secondary market shows that yields of municipal bonds increase sharply by 6 to 8 basis points before elections and then reverse afterward elections have more pronounced impact during economic downturns when outcomes are less predictable and when states have more outstanding debt several state institutions such as gaap budgeting spending limits and tax increase limits help to mitigate the adverse impact of political uncertainty

prospect theory and the risk return association an empirical examination in 85 industries a new sample of 85 industries about 3 300 firms defined in terms of homogenous products provides strong evidence that prospect theory can explain the tradeoff between two of the most researched parameters in evaluating organizations namely risk and return in particular organizations below their target level are found to be risk takers hl while organizations above their target level are risk averters h2 moreover the below target tradeofl was generally steeper than the above target with a median below to above slope ratio of about 3 l h3 risk and return are probably the two single parameters most researched by the various and related disciplines of economics finance and management although each one of them has looked at these two parameters from different aspects and for different purposes they have provided a wide understanding of these two factors in the contest of the theory of the firm the purpose of this study is to look closely at the relationship between these two important parameters in order to understand firm s competitive behavior using the recent development in behavioral decision theory namely prospect theory kahneman and tversky 1979 although march 1988 has criticized the discipline of management for its later adaptation in considering risk elements for evaluating organization performance and decision making processes recent studies e g bettis 1981 rumelt 1974 singh 1986 jemison 1987 and baird and thomas 1986 have paid considerable attention to risk aspects in evaluating the performance of firms in general these studies have concluded that the characteristics of the firms environment strategy and implementation processes have significant and important influence on the firm s risk level and its associated rate of return bowman 1980 has looked closely at 85 u s industries and explored the

toward a model of risk in declining organizations an empirical examination of risk performance and decline scholars who study organizational decline have argued that declining organizations reduce or eliminate their riskier activities such as innovation further they cite reduced risk taking as a primary contributor to further decline scholars with an interest in risk per se come to the opposite conclusion low performing firms often take more risks than other firms and such risks reduce subsequent performance this study attempts to resolve these conflicting views by examining the risk of firms in decline our model based on cyert march s cyert r m j g march 1963 a behavioral theory of the firm prentice hall englewood cliffs nj behavioral theory of the firm includes six basic variables 1 performance 2 slack 3 aspirations 4 expectations 5 risk income stream uncertainty and 6 organization size as a measure of decline the estimated model includes prior levels of risk and performance in the risk and performance equations respectively as controls this study uses data on 34

demographic pressure technological innovation and welfare the case of the agriculture of bangladesh in the early years of its introduction the hyv technology was widely regarded as a technical breakthrough that would bring about rapid agrarian progress and a revolutionary improvement in the standard of living of the farm population three decades later the promise of the new technology remains unfulfilled this article argues that the adoption of the hyv technology in the agriculture of bangladesh was determined mainly by an acute demographic pressure since the non agricultural sectors did not expand sufficiently rapidly there was a tremendous pressure on agriculture to accommodate the additional workforce the imperative to employ a larger workforce and feed a rising population forced the farmers to adopt the labour intensive land augmenting hyv technology the welfare of the farmers did not show any secular increase with the switch to the new technology

strategic reference point theory how can executives achieve a match between expected external environmental conditions and internal organizational capabilities that facilitates improved performance this paper argues that a firm s choice of reference points can help achieve strategic alignment capable of yielding improved performance and potentially even a sustainable competitive advantage building upon prospect theory and other relevant theoretical perspectives the strategic reference point srp matrix is developed a firm s srp consists of three dimensions internal capability external conditions and time a theory is developed which posits an optimal srp structure and propositions are offered which articulate the expected relationships between the srp strategic choice behavior and firm performance the paper closes with some suggestions for using strategic reference points in both research and practice

taxes default risk and yield spreads this paper develops a model of bond prices and yield spreads that incorporates the effect of both taxes and differences in default probabilities the tax loss consequences of default are recognized traditionally tax free municipal bond yields have been viewed as linearly related to taxable yields with a slope coefficient equal to one minus the tax rate and the intercept representing differences in default risk while our model supports the linearity assumption it implies that the slope and intercept are both functions of both the break even tax rate and the default probability ies clientele effects among both municipal and taxable bonds are demonstrated finally the implied marginal tax rates and the implied default probabilities are estimated for different categories of municipal bonds students of financial markets cannot help but be impressed by the number of new financial instruments that have been introduced successfully in recent years the fixed income market has been particularly innovative as bonds carrying a whole host of specific features have been successfully marketed bonds with small or zero coupons variable coupon rates or detachable warrants are three examples from among an expanding list of such features not surprisingly there has developed a large and expanding literature attempting to explain the rate spreads between different fixed income securities this literature has evolved much as one would expect early empirical work was in general not well founded in theory and was not based on an underlying expected return price model later empirical research has tended to be more careful in its specification of factors affecting yield spreads and as a consequence better founded in valuation

hypercompetition in a multimarket environment the role of strategic similarity and multimarket contact in competitive de escalation the effect of intra industry heterogeneity on hypercompetitive escalation and de escalation in a multimarket environment is examined the authors study two critical dimensions of intra industry heterogeneity strategic similarity which captures similarity in competitive orientation and multimarket contact which captures the degree of overlap between rivals in the multiple markets of the industry theory predicts that both variables influence the intensity of rivalry and competitive disruption the predictions in the literature about the effect of strategic similarity on the intensity of rivalry are mixed while strategic group theory proposes that strategic similarity may lead to lower rivalry other theories focusing on product differentiation the resource based view of the firm and hypercompetitive escalation predict that strategic similarity may actually increase rivalry those diametrically opposed propositions are captured as alternative hypotheses of the effect of strategic similarity with r

agricultural wages in bangladesh what the figures really show the impact of the green revolution on poverty has been the subject of much concern and fears that it leads to impoverishment have affected many people in a position to influence agricultural policy real agricultural wages rates have been used as an indicator of poverty in the absence of more direct measurements this article starts by examining two recent studies of the trends and regional variations of real agricultural wage rates in bangladesh both of which argue that agricultural growth has not been favourable to real wage rates one concludes that there has been an alarming downward trend since the mid 1960s and the other that the contribution of technological change to labour demand has not been strong using more recent information and re working the original data it appears that these conclusions cannot be supported

the pricing of corporate debt a note to develop a theory of the risk structure of interest rates r c merton 2 defines the risk as the possible gains or losses to bond holders as a result of unanticipated changes in the probability of default p 449 he derives the pricing theory of a pure discount bond corporation debt along the line of blackscholes 1 comparative statics are used to develop graphs of the risk structure although his algebraic derivation is correct his graphical presentation is inadvertently wrong

to be different or to be the same it s a question and theory of strategic balance this paper addresses the performance consequences of firm level strategic similarity past research observed that firms face pressures to be different and to be the same by differentiating firms reduce competition by conforming firms demonstrate their legitimacy both reduced competition and legitimacy improve performance this paper begins building a theory of strategic balance by synthesizing the differentiation and conformity perspectives the theory directs attention to intermediate levels of strategic similarity where firms balance the pressures of competition and legitimation empirical support for the theory is found in a longitudinal study of commercial banks several suggestions for developing a theory of strategic balance conclude the paper the theory s major implication is that firms should be as different as legitimately possible copyright 1999 john wiley sons ltd

a retrospective view of technological and other changes in philippine rice farming 1965 1982 much has been written about the impact of changes brought about through the introduction of semidwarf fertilizer responsive rice and wheat in asia the terms green revolution and miracle varieties suggest the dramatic effect anticipated from the new biological technology by both its supporters and detractors a great volume of literature has been generated describing the impact of these changes much of that literature is speculative some is theoretical and it would be fair to say much is cast in a tone with negative implications for new technology theoretical analyses necessarily balance simplifying assumptions with the richness of detail needed to capture the effects of technical and other changes while empirical analysis often shows what has happened but sheds little light on why it may have happened a recent review of the empirical literature shows that adoption of modern rice varieties in asia results in increased output has occurred quite evenly among farmers of all size groups and has resulted in modest increases in the use of labor per hectare of rice produced some empirical studies contrast areas that have adopted the technology with areas that have not thereby making the often false implicit assumption that all factors other than those specifically studied were similar other empirical studies concentrate on high adoption areas and use recall to infer how the introduction of technology may have changed variables of interest 2 there are a few pioneer studies available that contrast areas before and after the general adoption of specified technologies 3 this paper is a summary of ongoing research that provides data of the latter type researchers at the international rice research institute irri have monitored two sets of philippine rice producers for over 15 years during that period new rice technology was introduced and was

was the tax exempt bond market inefficient or were future expected tax rates negative this paper shows that the sharp narrowing with maturity of the spread between taxable and tax exempt yields leaves room for tax arbitrage at times tax exempt forward rates have exceeded taxable forward rates at such times only expectations of higher taxes on treasury than on municipal bonds would eliminate profit opportunities the authors develop the idea of forward tax rates and compute forward tax rates for 1955 through 1984 they also outline tax arbitrage mechanisms involving private forward sale of long municipal bonds or the use of the municipal bond futures contract and show the potential profits the municipal yield curve has been upward sloping for the entire postwar period even at times when taxable yield curves were humped or downward sloping thus the spread in yields between taxable and tax free bonds narrows dramatically with increasing maturity this paper focuses on the term structure of the spread in yields between taxable and tax exempt bonds we show that the sharp narrowing of the spread with maturity leaves room for some apparently unexploited tax arbitrage at times the narrowing has been so dramatic that taxexempt forward rates have exceeded taxable forward rates in other words only expectations of negative future tax rates on treasury interest or the expectations of a reversal in the relative taxability of treasury and municipal bonds would eliminate profit opportunities this situation makes little sense if the markets are well arbitraged three theories of the relationship between the yields on taxable and taxexempt bonds have attracted attention 2 miller 8 asserts that the corporate tax rate determines the yield spread between taxable and tax exempt debt in the

auction failures and the market for auction rate securities abstract the market for auction rate securities ars made headlines during the second week of february 2008 when auctions at which the bonds interest rates reset experienced a wave of failures contrary to headlines that attribute the failures to a frozen market or investors irrationality we find that 1 even at their height less than 50 of ars experienced auction failures 2 the likelihood of auction failure was directly related to the level of the bonds maximum auction rates 3 the implied market clearing yields of bonds with failed auctions were significantly above their maximum auction rates and 4 ars yields were generally higher than yields of various cash equivalent investment alternatives we infer that investors priced the possibility of auctions failures into ars yields and rationally declined to bid for bonds for which required market yields exceeded their maximum auction rates

the relative impact of actual and potential rivalry on firm profitability in the pharmaceutical industry this paper estimates the effects of actual and potential rivalry on profitability of firms in the u s pharmaceutical industry during the 20 year period 1963 82 the results show that during the 1960s actual rivalry among the sampled firms did not materially affect firm profitability but that during the 1970s competition among incumbents had an increasingly adverse effect on their profitability the results also show that potential competition significantly reduced drug firms profitability during the entire 20 year period copyright 1999 john wiley sons ltd

an analysis of land leasing in bangladesh agriculture economists applied 1989 data from 277 households in masimpur and darikandi bangladesh to a regression analysis to test their economic model which incorporated a partial adjustment mechanism into the bliss and stern leasing model the revised model did statistically very well further the coefficients were in the predicted direction and most were significant in addition the estimated values of the coefficients met the criteria of empirical plausibility in masimpur adjustments tended to be incomplete because almost 70 of the tenants were in the lease market for only or 2 years and did not have time to completely adjust on the other hand nearly 60 of the tenants in darikandi were in the leasing market for or 3 years and had more time to adjust to the desired area thus darikandi seemed to be in a state of equilibrium economists should be cautious in interpreting these results however the researchers could not standardize the unit of measurement of either land or family worker if the quality of these inputs differs considerably among households errors in variables ensues which in turn may result in a bias in the estimates of the coefficients further the leasing model is based on the assumption that the same coefficients that determine the amount of land leased in also determines the amount of land leased out yet if the landlords face adjustment problems that are significantly different from tenant adjustment problems the true model may be a misspecification in fact since agricultural land in bangladesh is quite scarce the leasing model may be doubtful

are individual investors tax savvy evidence from retail and discount brokerage accounts using brokerage account data we analyze the tax awareness of individual investors we find strong evidence that taxes matter investors prefer to locate bonds and mutual funds in retirement accounts and in december harvest stock losses in their taxable accounts however investors also trade actively in their taxable accounts realize gains more frequently than losses and locate a material portion of their bonds in taxable accounts though taxes leave clear footprints in the data we analyze many investors could improve their after tax performance by fully capitalizing on the tax avoidance strategies available to equities while optimally locating their assets

population growth and real wages of agricultural labourers in bangladesh a long run negative impact of population growth upon real wages is neither theoretically self evident nor in the case of rural bangladesh empirically clear cut in addition to its negative labour supply effect population growth may have a positive labour demand effect upon wages the latter may help to explain why bangladeshi districts with higher rural population densities have higher agricultural wages and why districts with more rapid population growth in the first half of this century subsequently experienced slower than average real wage declines an investigation of agricultural growth and agrarian structure as mediating variables in the population wage relation indicates that changes in average operational holding size inequality of landholdings and the extent and nature of tenancy contributed to this result

do investors value smooth performance abstract this paper presents empirical evidence that cash flow volatility is negatively valued by investors the magnitude of the effect is substantial with a 1 increase in cash flow volatility resulting in approximately a 0 15 decrease in firm value we show that this increase however is not associated with earnings smoothing resulting from managers accrual estimates our results are consistent with a preference by the market for less volatile cash flows and suggest that managers efforts to produce smooth financial statements add value but only via the cash component of earnings

antecedents of convergence and divergence in strategic positioning the effects of performance and aspiration on the direction of strategic change this paper investigates drivers of convergence and divergence in strategic positioning in terms of resource allocation decisions the study based on the behavioral theory of the firm suggests two unexplored kinked curve relationships between performance gaps and strategic convergence divergence first the study suggests a negative relationship between a focal firm s performance relative to aspiration levels and strategic convergence divergence where the slope is steeper when performance is above the aspiration level second it suggests a positive relationship between a target firm s performance relative to a focal firm s performance and strategic convergence divergence where the slope is steeper when a target firm s performance is below a focal firm s performance empirical analysis of dyad level data in the u s food processing industry reveals that the direction of a firm s strategic change is shaped by its aspiration level its performance level and the performance gap between it and the firm it selects as a model this study contributes to the current literature by offering preliminary indications of when and how a firm moves closer to or further away from other competing firms in its strategic position

determinants of firms backward and forward looking r d search behavior this study develops and operationalizes a behavioral forward looking search model by incorporating prospect theory organizational risk literature and the logic of the behavioral theory of the firm with recognition of the bounded rationality of decision makers and the goal directed rule based nature of organizations this model suggests that a comparison between firms performance expectation and performance target translates the cognitive representation of the firms future into their subsequent actions by examining the research and development r d expenditures of u s manufacturing firms from 1980 to 2001 this study explores how performance aspirations expectations and slack affect decision making about firms r d search investments the findings show that both performance feedback and performance prospect are important determinants of firms search behavior after controlling for firm industry and time effects in addition backward and forward looking determinants have interactive effects on search behavior firms problem driven search activity further increases when firms feel unlikely to achieve the performance target for another year in contrast search intensity is reduced when firms expect to improve their performance from an underperforming situation to an outperforming situation the findings suggest that future research on performance feedback and experiential learning should also consider the effect of forward looking prospects on firm behavior

borrowing cost reduction by interest rate swaps an option pricing analysis abstract interest rate swaps generally involve two firms with different credit ratings a quality spread differential qsd is observed to exist at different maturities for firm debts with different credit ratings the quality spread differential allows two firms with different credit ratings to decrease their borrowing costs through interest rate swaps by utilising their comparative advantage in borrowing in different markets the credit ratings of firms are determined by credit risk factors such as leverage and volatility of earnings asset value this paper investigates the effect of the leverage and the volatility on the behaviour of risk premia between firm debts with different credit ratings by using the contingent claim analysis our results show that the quality spread differential can be explained by the differences in leverage and volatility thus two firms with different leverage and volatility of earnings asset value will benefit from interest rate swaps however it is found that the duration within which the qsd exists is limited by the values of the leverage and the volatility of two firms in conclusion this paper shows that interest rate swaps can help the firms to lower borrowing costs without necessarily relying on the arbitrage argument asserted by existing literature

default risk cannot explain the muni puzzle evidence from municipal bonds that are secured by u s treasury obligations fama 1977 and miller 1977 predict that one minus the corporate tax rate will equate after tax yields from comparable taxable and tax exempt bonds empirical evidence shows that long term tax exempt yields are higher than theory predicts two popular explanations for this empirical puzzle are that relative to taxable bonds municipal bonds bear more default risk and include costly call options i study u s government secured municipal bond yields which are effectively default free and nonmalleable these municipal yields display the same tendency to be too high i conclude that differential default risk and call options do not explain the municipal bond puzzle article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

a multi attribute comparative evaluation of relative risk for a sample of banks abstract this paper proposes a comparative analysis of five different attributes of commercial banks liabilities that may be thought of as either directly measuring the default risk or are perceived by the market as impacting upon that default risk two of these attributes are credit ratings assigned by moody s and standard and poor s to debt issues the third attribute that we consider is yield to maturity which is typically assumed to be positively related to default risk the fourth attribute that is proposed is the fair value risk adjusted deposit insurance premium derived from option theoretic modeling and estimated from the daily data on equity prices finally we propose a term structure adjusted difference in yield between the risky debt and default free government debt as a more precise and theoretically sound measure of the default risk premium and develop a methodology for eliciting it on a composite basis for a given bank from the market prices of its various bond issues this term structure adjusted risk premium provides an analytical approximation to the valuation of corporate bonds call features and sinking fund provisions in view of the ordinality of the credit ratings given by the investment agencies spearman s rank correlation coefficient is employed as an analytical tool the analysis

tax subsidized underpricing the market for build america bonds build america bonds babs were issued by municipalities for 20 months as a part of the 2009 fiscal package unlike traditional tax exempt municipals babs are taxable to the holder but the treasury rebates 35 of the coupon to the issuer the stated purpose was to provide municipalities access to a more liquid market including foreign tax exempt and tax deferred investors we find babs do not exhibit greater liquidity than traditional municipals babs are more underpriced initially particularly for interdealer trades babs also show a substitution from underwriter fees toward more underpricing suggesting that the underpricing is a strategic response to the tax subsidy

agricultural wages in bangladesh what do the figures really show using new data and a different model palmer jones 1993 has questioned the conclusions of boyce and ravallion 1991 concerning the evolution over time of agricultural wages in bangladesh i argue that palmer jones s model is unconvincing and that the main conclusions of boyce and ravallion are far more robust than he suggests wages respond sluggishly to rice prices bangladesh s limited agricultural growth has not raised the real wage rate which was on a downward trend for most of the 1960s and 1970s the mid 1980s saw higher real wages though this cannot yet be deemed a reversal of the previous trend

a behavioral theory of market expansion based on the opportunity prospects rule what explains organizational search and choice when multiple opportunities are available to the decision makers drawing on the behavioral view of the firm and on the attention based view this study proposes a theoretical model centered on the opportunity prospects rule to explain market expansion defined as the extent how many and the selection which of multiple available opportunities that are actually pursued by competing firms we test our model using longitudinal fine grained data on commercial banks undertaking more than 1 300 opportunity choices the findings show that firms do use the opportunity prospects rule when exercising market expansion choices and that slack and performance feedback moderate the effects of opportunity prospects this paper contributes to organizational decision making research and to the behavioral view of the firm by showing the importance of considering an opportunity driven approach by demonstrating the relevance of simplifying rules to explain the search for the consequences of alternatives by extending recent efforts to provide a more forward looking perspective to model organization behavior and by showing when slack and performance feedback moderate the effects on market expansion of the opportunity prospects rule

pricing black scholes options with correlated credit risk abstract this paper presents an improved method of pricing vulnerable black scholes options under assumptions which are appropriate in many business situations an analytic pricing formula is derived which allows not only for correlation between the option s underlying asset and the credit risk of the counterparty but also for the option writer to have other liabilities further the proportion of nominal claims paid out in default is endogenous to the model and is based on the terminal value of the assets of the counterparty and the amount of other equally ranking claims numerical examples compare the results of this model with those of other pricing formulas based on alternative assumptions and illustrate how the model can be calibrated using market data

a simple model of the taxable and tax exempt yield curves i examine the anomalous behavior of the taxable and tax exempt yield curves long municipal yields appear too high relative to the equivalent after tax yield that can be earned in treasury or corporate bonds i discuss existing explanations of the problem and propose a simple model that relates the yields of taxable bonds to the yield curve for par tax exempts the ratio of the tax exempt yield to the taxable yield increases with maturity in the model so it is consistent with observed phenomena such as inverted yield curves for taxables and contemporaneous rising yield curves for tax exempts statistical and descriptive comparisons between the yields predicted by the model and observed yields on par bonds that the model has some promise in explaining the apparent anomalies in the behaviors of the two yield curves article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the term structure of interest rates in real and monetary economies abstract this paper modifies standard asset pricing models by introducing capital a variable labor supply and money a surprising but very positive result is that in a real production economy the interest rate is close to a random walk this result is found to be true even if there is no persistence in the driving process of the model in this paper we generalize the standard cash in advance constraint by using a shopping time technology this generalization makes it possible to match observed variability for the velocity of money this type of monetary model however is not successful in matching observed behavior of bond prices
