pricing variation within dual distribution chains the different implications of externalities and signaling for high and low quality brands within many of the multioutlet branded chains that dominate the retail and services landscape the organizational form e g company management franchising used to manage an outlet varies from site to site as do the prices charged at those sites i propose that organizational form and prices may be systematically related as a result of brand externalities in particular i develop logic that the relevant form of externality should differ for upper quality tier brands and lower tier brands using panel data on price and organizational form from more than 6 700 branded u s hotels affiliated with 40 dual distribution brands those brands that simultaneously company manage and franchise individual outlets i find that consistent with the brand externality arguments company managed locations have higher prices within high quality chains whereas franchisees price higher in the lower tiers this paper was accepted by bruno cassiman business strategy

the prisoners dilemma in the invisible hand an analysis of intrafirm productivity this paper attempts to show that it is useful to view productivity as a prisoners dilemma problem that conventions are alternative solutions to the prisoners dilemma that effort conventions are usually nonoptimal and that a shock is necessary in order to shift from one nonoptimal solution to another within this framework the invisible hand does not produce a pareto optimal result it is consistent with any number of nonoptimal effort conventions

interest rate swaps abstract using quotations from two interest rate swap dealers with different credit ratings aaa and a we examine the effect of dealers credit reputations on swap quotations and bid offer spreads the aaa offer rates are significantly higher than the a offer rates and the aaa bid rates are significantly lower than the a bid rates we also document the relation between swap rates and par bond yields estimated from london interbank offered rate libor and bid rate libid data we identify some of the problems in testing the implications of swap pricing theory

bond pricing and the term structure of interest rates a new methodology for contingent claims valuation this paper presents a unifying theory for valuing contingent claims under a stochastic term structure of interest rates the methodology based on the equivalent martingale measure technique takes as given an initial forward rate curve and a family of potential stochastic processee for its subsequent movements a no arbitrage condition restricts this family of processes yielding valuation formulae for interest rate sensitive contingent claims which do not explicitly depend on the market prices of risk examples are provided to illustrate the key results in relation to the term structure of interest rates arbitrage pricing theory has two purposes the first is to price all zero coupon default free bonds of varying maturities from a finite number of economic fundamentals called state variables the second is to price all interest rate sensitive contingent claims taking as given the prices of the zero coupon bonds this paper presents a general theory and a unifying framework for understanding arbitrage pricing theory in this context of which all existing arbitrage pricing models are special cases in particular vasicek 1977 brennan and schwartz 1979 langetieg 1980 ball and torous 1983 ho and lee 1986 schaefer and schwartz 1987 and artzner and delbaen 1988 the primary contribution of this paper however is a new methodology for solving the second problem i e the pricing of interest rate sensitive contingent claims given the prices of all zero coupon bonds the methodology is new because i it imposes its stochastic structure directly on the evolution of the forward rate curve ii it does not require an inversion of the term structure to eliminate the market prices of risk from contingent claim values and iii it has a stochastic spot rate process with multiple stochastic factors influencing the term structure the model can be used to consistently price and hedge all contingent claims american or european on the term structure and it is derived from necessary and more importantly sufficient conditions for the absence of arbitrage the arbitrage pricing models of vasicek 1977 brennan and schwartz 1979 langetieg 1980 and artzner and delbaen 1988 all require an iformerly titled bond pricing and the term structure of interest rates a new methodology

estimating the correlation structure of international share prices recently the case for international portfolio diversification has been convincingly argued in the framework of mean variance portfolio analysis by a number of researchers however virtually no empirical documentation exists concerning the best method for estimating the correlation structure of international share prices in this paper 12 models for estimating the international correlation matrix are presented and empirically tested relative to full historical extrapolation the major evaluation criteria are the mean squared error and stochastic dominance based on the frequency distribution of the squared forecast errors the results indicate that the national mean model strictly dominates all the others in terms of forecasting accuracy in the last fifteen years or so a number of researchers have convincingly argued the case for international portfolio diversification as opposed to purely domestic diversification in the framework of mean variance portfolio analysis see e g grubel 4 levy and sarnat 8 solnik 12 mcdonald 10 lessard 6 and subrahmanyam 15 1 in spite of the emerging consensus in the academic and investment communities that investors can benefit from international diversification in terms of a more efficient risk return tradeoff virtually no empirical documentation exists concerning the best method for estimating the correlation structure of international share prices since estimating this correlation structure is a necessary precondition for being able to apply modern portfolio theory to international investments empirical examination is of major importance moreover only through empirical examination of the correlation structure will the effort to devise a simple algorithm that can be used to solve for the optimal international portfolio be facilitated in order to trace out the set of ex ante efficient international porffolios using the tenets of modern portfolio theory the investor must obtain accurate estimates of the expected return and the variance of return for each domestic and foreign security and he must also obtain accurate estimates of the correlation coefficients of the returns between each pair of securities stated in terms of his numeraire

antecedents and performance implications of channel integration in foreign markets this study enhances our understanding of channel integration in foreign markets on two fronts first the eclectic approach to foreign entry mode proposed by hill hwang and kim 1990 and kim and hwang 1992 is used to examine transaction specific organizational capability and strategic factors that influence channel choices in foreign markets empirical results based on survey of u s firms support the combined relevance of these factors in predicting the degree of channel integration second the study empirically examines the performance consequences of channel integration the results suggest that although the degree of channel integration does not have a direct influence on channel performance a contingency model based on the fit between the contextual factors and the actual channel choice is significantly related to performance in foreign markets

great expectations and the end of the depression what ended the great depression in the united states this paper suggests that the recovery was driven by a shift in expectations this shift was triggered by president franklin delano roosevelt s fdr policy actions on the monetary policy side roosevelt abolished the gold standard and announced an explicit policy objective of inflating the price level to pre depression levels on the fiscal policy side roosevelt expanded real and deficit spending which helped make his policy objective credible the key to the recovery was the successful management of expecta tions about future policy roosevelt s rise to power is modeled as a policy regime change as in thomas sargent 1983 and peter temin and barry wigmore 1990 this paper formalizes temin and wigmore s argu ment in a repeated game setting using a dynamic stochastic general equilibrium dsge model and argues that the regime change can account for the recovery in the model a regime change means the elimination of certain policy dogmas that constrain the actions of the government the regime change generates an endogenous shift in expectations due to a coordination of mon etary and fiscal policy this coordination ended the great depression by engineering a shift in expectations from contractionary i e the private sector expected future economic contrac tion and deflation to expansionary i e the public expected future economic expansion and inflation the expectation of higher future inflation lowered real interest rates thus stimulating demand while the expectation of higher future income stimulated demand by raising permanent income

strategic implications of darwinian economics for selling efficiency and choice of integrated or independent sales forces most managers when confronted with a difficult strategic decision would like to know what is the prevailing practice in their industry prevailing practice interests managers in part because it may indicate which decisions are good even best the rationale is darwinian economics which proposes that competitive markets operate to force at least an approximation of optimal behavior because wrong decisions are extinguished by the market mechanism if so the bulk of survivors make good business decisions and their collective practice is worth knowing meaning it should be difficult to improve upon this paper tests whether prevailing practice represents good decisions the context is the decision whether to fill a sales district with a company integrated sales force or with outside agents independents the outcome of the choice is the ratio of sales to the cost of running the sales force i e selling efficiency a model is described which summarizes industry decisions and two propositions are developed proposition 1 a simple version states that efficiency declines as firms depart from the industry rule as to when they should integrate proposition 2 a contingent version states that efficiency declines as firms depart from the industry rule in unpredictable selling environments but that conforming to the rule has no impact in predictable environments the rationale is that firms learn the environment well enough to know when to depart from the rule in predictable settings but not otherwise the relationship between efficiency and conformity to prevailing practice is examined for 93 sales districts of 11 recognized electronic component manufacturers the results support proposition 2 the most efficient sales forces conform to prevailing practice and the least efficient deviate but only in uncertain environments in more certain environments conformity and efficiency are unrelated implications such as when it pays to be different and suggestions for future research are discussed

from m p to ma p multinationality alignment and performance rather than searching for a universal optimal level of multinationality for all firms we argue that firm specific attributes should result in firm specific optimal levels of multinationality specifically we draw upon transaction cost and internalization theory to argue that there will be different optimal levels of multinationality for individual firms and if firms internalize foreign operations to an extent less than or greater than their individual optimal levels transaction costs will increase and performance will decrease to test this idea we use transaction cost models in the context of large us law firms during the time period from 1986 through 2008 to estimate firm specific optimal multinationality next we test relationships between alignment with or deviations from firm specific optimal levels of multinationality and performance ma p consistent with the ma p hypothesis insufficient and excessive levels of multinationality are both negatively related to financial performance in addition excessive multinationality is positively associated with downside performance risk one key implication is that an ma p approach may offer greater theoretical validity and clarity than traditional multinationality and performance m p approaches

identification and the narrative approach a reply to leeper abstract contrary to the arguments of leeper 1997 the problems that arise in var investigations of monetary policy do not arise with our use of the narrative approach the apparent high predictability of our monetary policy variable that leeper finds is due to overfitting and the estimated effects of our measure when variables other than output are considered are unsurprising given leeper s specifications

chronicle of a deflation unforetold suppose the nominal money supply could be cut literally overnight by say 20 what would happen to prices wages output the answer can be found in 1720s france where just such an experiment was carried out repeatedly prices adjusted instantaneously and fully on one market only that for foreign exchange prices on other markets such as commodities as well as prices of manufactured goods and industrial wages fell slowly over many months and not by the full amount of the nominal reduction coincidentally or not the industrial sector as represented by manufacturing of woolen cloths experienced a contraction of 30 when the government changed course and increased the nominal money supply overnight by 20 prices responded much more and the woolen industry rebounded

influence activities and strategic coordination two distinctions of internal and external markets this paper examines empirically two distinctions of internal and external markets influence activities and strategic coordination influence activities that arise from decentralization imperfect monitoring and a relative performance system are a potential liability of internal markets coordination may be worse in internal markets than in external markets however strategic coordination is an advantage of internal markets a hierarchy can more effectively implement strategic policies in internal markets than external markets the results of this study show that profit center managers engage in influence activities by haggling over price adjustments causing greater renegotiation costs in internal markets than in comparable external markets however implementation of cost reduction which is a strategic policy appears to be more effective in internal markets the results show that supplying profit centers disclose more private cost information than external market suppliers thus cooperation and compe

the economics of organization the transaction cost approach the transaction cost approach to the study of economic organization regards the transaction as the basic unit of analysis and holds that an understanding of transaction cost economizing is central to the study of organizations applications of this approach require that transactions be dimensionalized and that alternative governance structures be described economizing is accomplished by assigning transactions to governance structures in a discriminating way the approach applies both to the determination of efficient boundaries as between firms and markets and to the organization of internal transactions including the design of employment relations the approach is compared and contrasted with selected parts of the organization theory literature

five facts about prices a reevaluation of menu cost models are price decreases 3 the frequency of price increases covaries strongly with inflation whereas the frequency of price decreases and the size of price increases and price decreases do not 4 the frequency of price change is highly seasonal it is highest in the first quarter and then declines 5 we find no evidence of upwardsloping hazard functions of price changes for individual products we show that the first second and third facts are consistent with a benchmark menu cost model whereas the fourth and fifth facts are not

the salesperson as outside agent or employee a transaction cost analysis this descriptive study explores the reasons for integration of the personal selling function i e the use of employee direct salespeople rather than manufacturers representatives reps a hypothesized model is developed based on both transaction cost analysis and the sales force management literature data from 13 electronic component manufacturers covering 159 u s sales districts are used to estimate a logistic model of the probability of going direct in a given district results are shown to be stable across specification and estimation methods and to fit the data well the transaction cost model is generally supported the principal finding is that the greater the difficulty of evaluating a salesperson s performance the more likely the firm to substitute surveillance for commission as a control mechanism i e to use a direct sales force among other findings direct sales forces are also associated with complex hard to learn product lines and with districts that demand considerable nonselling activities several factors prove unrelated including company size the amount of travel a district requires and the importance of key accounts this article was originally published in marketing science volume 4 issue 3 pages 234 254 in 1985

the fed and interest rates a high frequency identification we measure monetary policy shocks as changes in the fed funds target rate that surprise bond markets in daily data these shock series avoid the omitted variable time varying parameter and orthogonalization problem of monthly vars and do not impose the expectations hypothesis we find surprisingly large and persistent responses of bond yields to these shocks 10 year rates rise as much as 8 10 of a percent to a one percent target shock the usual view that monetary policy only temporarily raises long term rates and influences inflation would lead one to predict a negative long rate response this abstract was borrowed from another version of this item

the antecedents and performance implications of cooperative exchange norms our study investigates the antecedents and performance implications of cooperative exchange norms we argue that in early relationships the level of expected cooperative norms in an exchange is the result of a calculative process facilitated by transaction attributes joint transaction specific investments and observability the greater the level of these two exchange attributes the greater the level of cooperative exchange norms all else being equal we further argue that the realized level of cooperative exchange norms can deviate from the expected level because the development of such norms is the result of social processes that management cannot directly and fully control this gap between realized and expected norms affects exchange performance performance suffers when the realized level of cooperative exchange norms falls below the expected level but overshooting expectations lays a critical groundwork for repeat transactions the analysis of a survey of 182 collaborative r d alliances provides initial support for our theory

identification in macroeconomics abstract this paper discusses empirical approaches macroeconomists use to answer questions like what does monetary policy do how large are the effects of fiscal stimulus what caused the great recession why do some countries grow faster than others identification of causal effects plays two roles in this process in certain cases progress can be made using the direct approach of identifying plausibly exogenous variation in a policy and using this variation to assess the effect of the policy however external validity concerns limit what can be learned in this way carefully identified causal effects estimates can also be used as moments in a structural moment matching exercise we use the term identified moments as a short hand for estimates of responses to identified structural shocks or what applied microeconomists would call causal effects we argue that such identified moments are often powerful diagnostic tools for distinguishing between important classes of models and thereby learning

factor models and the correlation structure of interest rates some evidence for usd gbp dem and jpy abstract the aim of this paper is to develop models for producing accurate forecasts for the correlation of spot and forward interest rates correlation forecasts generated from factor models where the correlations are expressed as a function of few underlying factors are compared to forecasts produced by less sophisticated models like the full historical and constant correlation model contrary to previous studies where the selection of factors is rather arbitrary we test two factor identification methodologies the first is based on factor analysis and the second is based on minimising the residual cross correlations we show that a three factor model with factors identified by minimising the residual cross correlation criterion is sufficient to describe the correlation structure of interest rates furthermore we show that it might be preferable to assume that all forward rate correlations are equal rather than using a misspecified factor model and that the spot factor model developed consistently outperformed long established models like the barbell model

stability and forecasting of the comovement measures of international stock market returns abstract the potential benefits to international diversification may be less if the comovement structure of international equity returns is non stationary than if it is this paper examines the intertemporal stability of the correlation and the covariance structure of the returns of ten major stock markets whilst empirical evidence supports the hypothesis that the correlation structure is stable over time the empirical support for the stability of the covariance matrix is much weaker alternative forecasting models of the comovement structure are examined

explorations into factors explaining money market returns in this article we measure and interpret the common factors that describe money market returns results are presented for both three and four factor models we find that the three factor model explains on average 86 percent of the total variation in most money market returns while the four factor model explains on average 90 percent of this variation using mimicking portfolios we provide an interpretation of the systematic risks represented by these factors in this article we attempt to measure and interpret the common factors that describe money market returns the factor approach we employ assumes that the covariance matrix of a set of random variables in this case excess returns can be decomposed into common or systematic components and idiosyncratic or nonsystematic components this decomposition into systematic and nonsystematic components is based on an assumption of a linear relationship between the returns of each security and a set of common factors this is the assumption of linear return generating models which form an integral part of the structure of many asset pricing theories for example arbitrage pricing theory apt as developed by ross 1976 the interpretation is that the common factors represent sources of systematic or nondiversifiable risk and the idiosyncratic component of returns represents diversifiable risks our focus here is not on testing a particular asset pricing model per se but on developing empirical evidence for the existence of stylized facts regarding money market returns the stylized facts take the form of the existence measurement and interpretation of the common factors that are found in money markets our attempt to measure and interpret these sources of systematic risk may eventually lead to the construction of observable eco

consumption versus expenditure previous authors have documented a dramatic decline in food expenditures at the time of retirement we show that this is matched by an equally dramatic rise in time spent shopping for and preparing meals using a novel data set that collects detailed food diaries for a large cross section of u s households we show that neither the quality nor the quantity of food intake deteriorates with retirement status we also show that unemployed households experience a decline in food expenditure and food consumption commensurate with the impact of job displacement on permanent income these results highlight how direct measures of consumption distinguish between anticipated and unanticipated shocks to income whereas measures of expenditures obscure the distinction
