shaky roads and trembling exports assessing the trade effects of domestic infrastructure using a natural experiment abstract our knowledge of the trade effects of domestic infrastructure is very limited the reason is twofold first data needed to examine these effects are not readily available second identifying such effects requires properly addressing potential endogeneity problems affecting the relationship between internal infrastructure and trade in this paper we overcome these limitations by combining firm level export data with detailed geo referenced information on chile and by exploiting the earthquake that took place in this country in 2010 as an exogenous source of variation in available infrastructure and thereby in transport costs we find that diminished transportation infrastructure had a significant negative impact on firms exports

the district effect and the competitiveness of manufacturing companies in local productive systems the present study evaluates the existence of differences in competitiveness of spanish industrial firms as a consequence of the district effect a quantitative analysis has been performed in order to assess external competitiveness taking into account whether firms are located in industrial districts in the sense proposed by marshall becattini or remain isolated the methodological approach considers geographical and sectoral variables it attempts to establish the existence of a relationship between sectoral specialisation and business efficiency measured as the capacity to export in local productive systems most of the variables come from a 1991 fiscal data set and the territorial units of analysis are 332 municipalities with a population of over 15 000 inhabitants from the results on the econometric model it can be inferred that the geographical concentration of companies in the same activity positively influences their level of competitiveness

accounting for a shift in term structure behavior with no arbitrage and macro finance models this paper examines a shift in the dynamics of the term structure of interest rates in the u s during the mid 1980s we document this shift using standard interest rate regressions and using dynamic a ne no arbitrage models estimated for the pre and post shift subsamples the term structure shift largely appears to be the result of changes in the pricing of risk associated with a level factor using a macro nance model we suggest a link between this shift in term structure behavior and changes in the dynamics and risk pricing of the federal reserve s in ation target as perceived by investors

no arbitrage near cointegrated var p term structure models term premia and gdp growth abstract the recent macro finance literature does not agree either about the empirical properties of the expectation part and of the term premium on long term bonds or about the importance or even the direction of the relationship between the term premium and future economic activity this paper proposes a two step approach to handle both problems first in a var setting we extract a reliable measure of the term premium by means of averaging estimator techniques aiming at optimally solving prediction problems when highly persistent processes are present and thus providing a so called near cointegrated var p approach second we analyze the dynamic response of gdp to shocks to the term premium by using the new information response function concept as far as the first problem is concerned we find that the ncvar based term premium measure is rather stable and counter cyclical as suggested by interest rates survey based estimation of yield curve models and by its risk compensation role regarding the second problem we find that an increase in the long term spread caused by the term premium induces two effects on future economic activity the impact is negative for short horizons less than 1 year whereas it is positive for longer ones

domestic trade and transportation costs as barriers to international trade available evidence indicates that costs of nontraded services in domestic transportation wholesaling and retailing domestic margins are higher if a good is shipped in international trade than if it is shipped from domestic producers to domestic consumers consequently domestic margins appear to act as natural barriers to trade in the same manner as international transp ort costs do this paper presents estimates of the barriers that the domestic margins impose against u s imports and shows that they exc eed the barriers imposed by tariffs and international transport costs combined

practice prize report an assortmentwide decision support system for dynamic pricing and promotion planning in diy retailing the main objective of this report is to describe a decision support system for dynamic retail pricing and promotion planning our weekly demand model incorporates price reference price effects seasonality article availability information features and discounts building on previous research we quantify demand interdependencies and integrate the resulting profit lifting effects into the optimal pricing model the methodology was developed and implemented at baumax an austrian do it yourself retailer along with the practical requirements an objective function was employed that can be used as a vehicle for implementing a retailer s strategy eight pricing rounds with thousands of different stock keeping units have each served as a testing ground for our approach based on various benchmarking methods a positive impact on profit was reported the currently implemented marketing decision support system increased gross profit on average by 8 1 and sales by 2 1

the term structure of euro interest rates and rational expectations abstract this paper analyzes the short end of the maturity spectrum of euro interest rates using recent monthly data the data for the euro franc and euro dm interest rates support the rational expectations hypothesis whereas those true for euro dollar interest rates do not this result is explained by the different approaches used to conduct monetary policy in the usa switzerland and west germany

a joint model for the term structure of interest rates and the macroeconomy we present and estimate a continuous time term structure model that incorporates observable macroeconomic variables and latent variables with a clear macroeconomic interpretation our model is able to accurately describe the joint dynamics for us macroeconomic variables and the yield curve however the observable variables do not explain the long end of the term structure central tendencies of these macroeconomic variables do a much better job in this respect these unobservable factors also play an important role in the description of the interest rate policy rule both observable and non observable factors determine the risk premia and hence bond excess holding returns copyright 2006 john wiley sons ltd

macroeconomics and the term structure this paper provides an overview of the analysis of the term structure of interest rates with a special emphasis on recent developments at the intersection of macroeconomics and finance the topic is important to investors and also to policymakers who wish to extract macroeconomic expectations from longer term interest rates and take actions to influence those rates the simplest model of the term structure is the expectations hypothesis which posits that long term interest rates are expectations of future aver age short term rates in this paper we show that many features of the configuration of interest rates are puzzling from the perspective of the expectations hypothesis we review models that explain these anomalies using time varying risk premia although the quest for the fundamental macroeconomic explanations of these risk premia is ongoing inflation uncertainty seems to play a large role finally while modern finance theory prices bonds and other assets in a single unified framework we also consider an earlier approach based on segmented markets market segmentation seems important to understand the term structure of interest rates during the recent financial crisis jel e31 e43 e52 e58

risk aversion intertemporal substitution and the term structure of interest rates an equilibrium model of the term structure of interest rates is derived from a representative agent framework with recursive utility preferences a key ingredient is a time varying subjective discount factor which is linked to the short term rate of interest the proposed model incorporates a vector autoregression description of macroeconomic dynamics and links them to those of the term structure so that nominal bond yields are affine functions of observable state variables the model is estimated and compared to both a restricted expected utility version of the model and a reduced form no arbitrage model we find that all three models can fit the term structure equally well but that only the unrestricted non expected utility model can empirically account for the tent shaped pattern and magnitude of coefficients from predictive regressions of excess bond returns on forward rates documented by cochrane and piazzesi 2005 bond risk premia american economic review 95 138 160 the unrestricted equilibrium model fits the term structure and captures the important features of bond risk premiums with economically plausible values for the structural preference parameters

uncovering the us term premium an alternative route abstract the estimates of the us term premium crucially depend upon the ex ante decision on whether the short term rate is either an i 0 or an i 1 process in this paper we estimate a fractionally integrated i d model which simultaneously determines both the order of integration of the short term rate and the associated term premium we show that the term premium experienced a sharp increase from essentially zero in mid 2007 to almost 3 in 2009 we also show that unemployment and term premium dynamics exhibit a very significant positive co movement

monetary policy bond risk premia and the economy within an affine model of the term structure of interest rates where bond yields get driven by observable and unobservable macroeconomic factors parameter restrictions help identify the effects of monetary policy and other structural disturbances on output inflation and interest rates and decompose movements in long term rates into terms attributable to changing expected future short rates versus risk premia when estimated the model highlights a broad range of channels through which monetary policy affects risk premia and the economy risk premia affect monetary policy and the economy and the economy affects monetary policy and risk premia

the impact of heterogeneity in purchase timing and price responsiveness on estimates of sticker shock effects the notion that individuals have an internal reference price against which they compare observed prices is well supported by several psychological theories empirically several papers in the marketing literature employing scanner panel data have modeled the impact of reference prices on brand choice via the sticker shock formulation in which consumers evaluate choice alternatives using differences between shelf prices and reference prices most of the studies reported thus far have not accounted for heterogeneity in price response among consumers and have typically imputed reference prices from the shelf prices of brands that a consumer is supposed to have observed on previous purchases in the category since category marketing activity can differentially affect the purchase timing of households we argue that this measure of reference price may follow certain systematic patterns across consumers and when combined with unaccounted for price response heterogeneity may result in a spurious sticker shock effect specifically we show that estimates of sticker shock are biased upward if households that are price sensitive in the brand choice decision are also more responsive to category promotion activity in their purchase timing decision we discuss some general conditions under which the bias occurs and conduct a simulation experiment to confirm our specific hypotheses our simulation results show that changes in purchase timing are a critical determinant of the bias in the sticker shock effect we also show that unaccounted for price response heterogeneity can in itself result in a biased sticker shock parameter however this requires very large differences in price sensitivities across consumers far greater than what is normally observed we develop a hierarchical bayes version of the nested logit model which models heterogeneity via individual level parameters in a continuous random effects framework we estimate the model on scanner panel data from the yogurt and ketchup categories we find in both categories that the 95 probability interval of the posterior distribution of the mean sticker shock coefficient contains the value zero therefore at least for the data used in this study there is no evidence for the sticker shock effect at the aggregate level in contrast the corresponding coefficient from a standard model which ignores this heterogeneity is highly significant and supports the existence of a possibly spurious sticker shock effect consistent with our explanation of the underlying cause of the bias households that are more price sensitive in the choice decision are also found to be more responsive to category promotion activity in their decision to purchase in the category the results highlight the measurement problems associated with imputing reference prices from past prices since the frequency duration and price level of a retailer s promotional program depend on its size and prevalence accurate estimates of the sticker shock effect are essential for formulating optimal promotion strategies an adequate accounting of consumer heterogeneity is critical to this effort

term premia and inflation uncertainty empirical evidence from an international panel dataset this paper provides cross country empirical evidence on bond risk premia i construct a panel of zero coupon nominal government bond yields spanning ten industrialized countries and nearly two decades i hence compute forward rates and then use two different methods to decompose these forward rates into expected future short term interest rates and term premiums the first method uses an affine term structure model with macroeconomic variables as unspanned risk factors the second method uses surveys i find that term premium estimates declined across countries over the sample period especially in countries that appear to have reduced inflation uncertainty by making substantial changes in the monetary policy frameworks of their central banks during the recent financial crisis term premiums have remained flat and even declined further in some countries perhaps reflecting the effects of quantitative easing actions by many central banks

modeling loss aversion and reference dependence effects on brand choice based upon a recently developed multiattribute generalization of prospect theory s value function tversky and kahneman 1991 we argue that consumer choice is influenced by the position of brands relative to multiattribute reference points and that consumers weigh losses from a reference point more than equivalent sized gains loss aversion we sketch implications of this model for understanding brand choice we develop a multinomial logit formulation of a reference dependent choice model calibrating it using scanner data in addition to providing better fit in both estimation and forecast periods than a standard multinomial logit model the model s coefficients demonstrate significant loss aversion as hypothesized we also discuss the implications of a reference dependent view of consumer choice for modeling brand choice demonstrate that loss aversion can account for asymmetric responses to changes in product characteristics and examine other implications for competitive strategy

are external shocks responsible for the instability of output in low income countries external shocks such as commodity price fluctuations natural disasters and the role of the international economy are often blamed for the poor economic performance of low income countries the author quantifies the impact of these different external shocks using a panel vector autoregression var approach and compares their relative contributions to output volatility in low income countries vis a vis internal factors he finds that external shocks can only explain a small fraction of the output variance of a typical low income country internal factors are the main source of fluctuations from a quantitative perspective the output effect of external shocks is typically small in absolute terms but significant relative to the historic performance of these countries

urban growth and transportation we estimate the effects of interstate highways on the growth of u s cities between 1983 and 2003 we find that a 10 increase in a city s initial stock of highways causes about a 1 5 increase in its employment over this 20 year period to estimate a structural model of urban growth and transportation we rely on an instrumental variables estimation that uses a 1947 plan of the interstate highway system an 1898 map of railroads and maps of the early explorations of the u s as instruments for 1983 highways we investigate the role of interstate highways in the growth of u s cities our investigation is in three parts in the first we develop a simple structural model describing the joint evolution of highways and employment in cities in the second we develop an instrumental variables strategy that allows us to identify key parameters of our structural model we are also able to provide out of sample evidence for the validity of our estimates and for the central assumptions of our model in the third we use our estimates to assess counterfactual transportation policies we find that a 10 increase in a city s stock of interstate highways causes about a 1 5 increase in its employment over 20 years and that an additional kilometre of highway allocated to a city at random is associated with a larger increase in employment or population than is a road assigned to a city by the prevailing political process our results also suggest that too many new highways were built between 1983 and 2003 these findings are important for three reasons first transportation generally and infrastruc ture in particular are large segments of the economy the median u s household devotes about 18 of its income to road transportation while all levels of government together spend another 200 billion dollars annually overall the value of capital stock associated with road transporta tion in the u s tops 5 trillion dollars united states bureau of transportation statistics 2007 2010 given the magnitude of transportation expenditures it is important that the impact of these expenditures on economic growth be carefully evaluated and not assessed on the basis of the claims of advocacy groups our analysis provides a basis for assessing whether these resources are well allocated our results also provide useful guidance to policy makers charged with planning cities since changes in a city s transportation infrastructure cause changes to the city s employment new transportation infrastructure causes complementary changes in the demand for public utilities and schools our results provide a basis for estimating the magnitude of such changes finally this research is important to furthering our understanding of how cities operate and grow transportation costs are among the most fundamental quantities in theoretical models

the persistence of marketing effects on sales are marketing efforts able to affect long term trends in sales or other performance measures answering this question is essential for the creation of marketing strategies that deliver a sustainable competitive advantage this paper introduces persistence modeling to derive long term marketing effectiveness from time series observations on sales and marketing expenditures first we use unit root tests to determine whether sales are stable or evolving trending over time if they are evolving we examine how strong this evolution is univariate persistence and to what extent it can be related to marketing activity multivariate persistence an empirical example on sales and media spending for a chain of home improvement stores reveals that some but not all advertising has strong trend setting effects on sales we argue that traditional modeling approaches would not pick up these effects and therefore seriously underestimate the long term effectiveness of advertising the paper concludes with an agenda for future empirical research on long run marketing effectiveness

predicting u s recessions financial variables as leading indicators this paper examines the out of sample performance of various financial variables as predictors of u s recessions series such as interest rates and spreads stock prices and monetary aggregates are evaluated individually and in comparison with other financial and nonfinancial indicators the analysis focuses on out of sample performance from one to eight quarters ahead results show that stock prices are useful with one to three quarter horizons as are some well known macroeconomic indicators beyond one quarter however the slope of the yield curve emerges as the clear individual choice and typically performs better by itself out of sample than in conjunction with other variables

specifying price judgments with range frequency theory in models of brand choice abstract to construct a price judgment consumers compare a focal price with one or more reference prices however reference price operationalizations in the brand choice literature use single point summary measures that cannot account for several distributional effects to account for effects beyond the first moment of the reference price distribution the authors specify price judgments in models of brand choice in accordance with range frequency theory the findings indicate that range frequency price judgments provide a more complete specification of reference price effects and become more important with an increase in the second and third moments of a reference price distribution the data also indicate that range effects are stronger for coupon users and frequency effects are stronger for consumers exposed to a trend of prices the results have several implications for choice modeling pricing theory and pricing strategy

a competitive dynamic pricing model when demand is interdependent over time abstract in this study we contribute to the dynamic pricing literature by developing a finite horizon model for two firms offering substitutable and nonperishable products with different quality levels customers can purchase and store the products even if they do not need them at the time in order to use them in future the stockpile of the products generated by customers affects the demand in future periods therefore the demand for each product not only is a function of prices and quality levels but also of the products stockpile levels in addition the stockpile levels change the customers consumption behavior more product in a stockpile leads to more consumption therefore we address not only the price and demand relationship but also the stockpiling and consumption relationship in a competitive environment the decision variable of each firm at the beginning of each period is its unit sale price we use a deterministic dynamic program to calculate the equilibrium prices at the beginning of each period by assuming that the market stockpile is public information we show the existence of a unique nash equilibrium we next consider the case when the firms do not know the market stockpile we then develop appropriate heuristics to calculate the optimal prices in each case a numerical study is also provided to calculate the price levels in different scenarios and compare their performances

the bright side of loss aversion in dynamic and competitive markets a well established phenomenon of consumer buying behavior is that consumers evaluate prices relative to a reference point and exhibit loss aversion i e their propensity to buy is more negatively affected by prices above the reference point than it is positively affected by prices below the reference point the objective of this paper is to analytically examine how the competitive strategy and profitability of firms are affected by the presence of consumer loss aversion in the price dimension although we assume that consumer loss aversion increases consumer propensity to search for lower prices we find that it does not necessarily lead to lower prices or profits when firms compete over multiple periods and when the consumer reference price in subsequent periods is affected by current prices specifically consumer loss aversion could lead to higher prices and profits when consumer valuation is sufficiently high relative to search costs and the proportion of consumers with positive search costs is in an intermediate range we also show that when forward looking firms incorporate the negative effect of price promotions on future profits the equilibrium range of price promotions may actually increase

school decentralization helping the good get better but leaving the poor behind abstract the decentralization of public services is a major feature of institutional innovation the main argument in support of decentralization is that it brings decisions closer to the people thereby alleviating information asymmetries and improving accountability however decentralization can also degrade service provision in poor communities that lack the ability to voice and defend their preferences in this paper we analyze the average and distributional effects of school decentralization on educational quality in argentina we find that decentralization had an overall positive impact on student test scores the decentralization gains however did not reach the poor thus although bringing decisions closer to the people may help the good get better the already disadvantaged may not receive these benefits

consumer uncertainty and purchase decision reversals theory and evidence this research examines how prepurchase information that reduces consumer uncertainty about a product or service can affect consumer decisions to reverse an initial product purchase or service enrollment decision one belief commonly held by retailers is that provision of greater amounts of information before the purchase reduces decision reversals we provide theory and evidence showing conditions under which uncertainty reducing information provided before the purchase decision can actually increase the number of decision reversals predictions generated from an analytical model of consumer behavior incorporating behavioral theory of reference dependence are complemented by empirical evidence from both a controlled behavioral experiment and econometric analysis of archival data combined the theory and evidence suggest that managers should be aware that their information provision decisions taken to reduce decision reversals may actually increase them data as supplemental material are available at http dx doi org 10 1287 mksc 2015 0906

macro factors and the term structure of interest rates this paper presents an essentially affine model of the term structure of interest rates making use of macroeconomic factors and their long run expectations the model extends the approach pioneered by kozicki and tinsley 2001 by modeling consistently long run inflation expectations simultaneously with the term structure application to the u s economy shows the importance of long run inflation expectations in the modeling of long term bond yields the paper also provides a macroeconomic interpretation for the latent factors found in standard finance models of the yield curve the level factor represents the long run inflation expectation of agents the slope factor captures business cycle conditions and the curvature factor expresses a clear independent monetary policy factor

an empirical comparison of the validity of a neural net based multinomial logit choice model to alternative model specifications applications of choice models to brand purchase data as a rule specify a linear deterministic utility function we estimate deterministic utility by means of a neural net able to approximate any continuous multivariate function and its derivatives to a desired level of precision we compare this model to related alternatives both with linear and nonlinear utility functions alternatives with nonlinear utility functions are based on generalized additive modeling and taylor series expansion respectively we analyze purchase data of the six largest brands in terms of market share for two product groups neural choice models outperform the alternative models studied w r t posterior probabilities they also attain the best crossvalidated log likelihood values these results demonstrate that the increase in complexity caused by the neural choice model is justified by higher validity in the empirical study the neural choice models imply elasticities different from those obtained by linear utility multinomial logit models for several predictors neural choice models discover inversely s shaped saturation and interaction effects on utility

the yield curve and macroeconomic dynamics we show that microfounded dsge models with nominal rigidities can be successful in replicating features of bond yield data including sizeable term premia and volatile long term yields which have previously been considered puzzling in general equilibrium frameworks at the same time sample moments of consumption growth and inflation can be fit relatively well the improved model performance does not arise directly from the presence of nominal rigidities however this feature introduces short run monetary non neutrality so that monetary policy affects consumption dynamics and bond prices a high degree of interest rate smoothing in the policy rule is essential for our results at the core of dynamic macroeconomic models we find equilibrium relationships which describe the allocation of quantities e g consumption and investment and when imperfect competition prevails the setting of prices these equations are typically valid across time and across states of nature and financial assets form the tool that is supposed to ensure their validity financial assets are therefore an integral part of macroeconomic models any well specified model should be able to match financial data as well as macro data it is therefore problematic that microfounded models have had a hard time explaining key features of asset prices the most famous example of this difficulty is the equity premium puzzle but various features of bond yield data have also been char acterised as puzzling in the literature a number of papers including backus et al 1989 donaldson et al 1990 den haan 1995 and chapman 1997 have con cluded that general equilibrium models cannot generate term premia of a magnitude comparable to what we observe in actual data and may not even be capable of producing positive term premia for equity one could argue that fundamentals the expected future profitability of individual firms are unobservable and difficult to evaluate equity prices may therefore be thought to be subject to fluctuations disconnected from the real economy information acquisition fads etc and one could hope that the inability of macroeconomic models to match equity prices does not represent a signal of misspecification this argument is more difficult to construct for bonds bond yields should ultimately reflect expectations of future monetary policy decisions which at least in recent years are arguably more predictable than equity fundamentals thus the ability of macroeconomic models to explain bond prices represents an important test of their empirical performance in this article we revisit the relationship between bond prices and macroeconomic fundamentals contrary to the papers cited above that rely on flexible price models we

modeling multiple sources of heterogeneity in multinomial logit models methodological and managerial issues we offer a framework to specify and estimate various sources of heterogeneity in multinomial logit brand choice models we let each brand specific intercept and each parameter of the explanatory variable vector vary randomly across households in addition we distinguish loyal households from the rest our results suggest that incorporating multiple sources of heterogeneity improves the model fit and suggests higher impact of marketing mix elements on brand choice we highlight the importance of incorporating multiple sources of heterogeneity the model we implement yields valuable managerial insights

roads to prosperity assessing the link between public capital and productivity does the positive correlation between infrastructure and productivity reflect causation if so in which direction the author finds that when growth in roads the largest component of infrastructure changes productivity growth changes disproportionately in u s industries with more vehicles that vehicle intensive industries benefit more from road building suggests that roads are productive at the margin however road investments do not appear unusually productive intuitively the interstate system was highly productive but a second one would not be road building thus explains much of the productivity slowdown through a one time unrepeatable productivity boost in the 1950s and 1960s

domestic road infrastructure and international trade evidence from turkey poor domestic transportation infrastructure in developing countries is often cited as an important impediment for accessing international markets yet evidence on how transportation infrastructure improvements affect the volume and composition of exports is scarce drawing on the large scale public investment in expressways undertaken in turkey during the 2000s this paper contributes to our understanding of how internal trade costs affect regional exports and specialization two results emerge first we estimate that this road infrastructure project accounts for 15 percent of the export increase from interior regions generating a 10 year discounted stream of additional export revenues that amount to between 9 and 14 percent of the value of the investment second while the exports of all industries within a given region increase in response to improvements in connectivity to the international gateways of the country the magnitude of this increase is larger the more time sensitive an industry is accordingly we also observe an increase in the regional employment and revenue shares of such industries our results support the hypothesis that internal trade costs can be a determinant of international specialization and comparative advantage

the macroeconomic consequences of disasters abstract natural disasters have a statistically observable adverse impact on the macro economy in the short run and costlier events lead to more pronounced slowdowns in production yet interestingly developing countries and smaller economies face much larger output declines following a disaster of similar relative magnitude than do developed countries or bigger economies a close study of the determinants of these adverse macroeconomic output costs reveals several interesting patterns countries with a higher literacy rate better institutions higher per capita income higher degree of openness to trade and higher levels of government spending are better able to withstand the initial disaster shock and prevent further spillovers into the macro economy these all suggest an increased ability to mobilize resources for reconstruction financial conditions also seem to be of importance countries with more foreign exchange reserves and higher levels of domestic credit but with less open capital accounts appear more robust and better able to endure natural disasters with less adverse spillover into domestic production

short rate nonlinearities and regime switches abstract using non parametric estimation methods various authors have shown distinct non linearities in the drift and volatility function of the us short rate which are inconsistent with standard affine term structure models we document how a regime switching model with state dependent transition probabilities between regimes can replicate the patterns found by the non parametric studies to do so we use data from the uk and germany in addition to us data and include term spreads in some of our models we also examine the drift and volatility function of the term spread

a macro finance model of the term structure monetary policy and the economy this paper develops and estimates a macro finance model that combines a canonical affine no arbitrage finance specification of the term structure with standard macroeconomic aggregate relationships for output and inflation from this new empirical formulation we obtain several interesting results 1 the latent term structure factors from finance no arbitrage models appear to have important macroeconomic and monetary policy underpinnings 2 there is no evidence of monetary policy inertia or a slow partial adjustment of the policy interest rate by the federal reserve and 3 both forward looking and backward looking elements play important roles in macroeconomic dynamics

benchmarking the expectations hypothesis of the interest rate term structure an analysis of cointegration vectors i test cointegration restrictions that are consistent with the expectations hypothesis of the term structure by employing the full information maximum likelihood methods developed by johansen yield curves appear to be the result of cointegration among interest rates the cointegration vectors that best describe the long term impact of interest rate levels on interest rate changes can often be written as linear combinations of interest rate spreads there is however difficulty in keeping short term yields in such a restricted cointegrated system with other interest rates short term speculative returns from long term bonds do not conform to the expectations hypothesis

predicting competitive response to a major policy change combining game theoretic and empirical analyses this research uses procter gamble s value pricing initiative as a context for testing whether actual competitor and retailer response to a major policy change can be predicted using a game theoretic model we first estimate demand functions for p g and competitor brands from the period before value pricing was initiated we then formulate a dynamic manufacturer retailer stackelberg model that includes p g a national brand competitor and a retailer the model takes p g s move as given and prescribes the price and promotion response of the competitors and the retailer we substitute the estimated demand parameters into the model to obtain prescriptions for each competitor and the retailer and see whether these prescriptions are related to the actual response we find that the dynamic game theoretic model calibrated with empirical estimates of demand parameters has significant predictive power we also test the predictive power of two benchmark models the first is based on the reaction function approach of leeflang and wittink leeflang peter s h wittink dick r 1992 diagnosing competitive reactions using aggregated scanner data internat j res marketing9 39 57 and the second is a simplification of our dynamic model where the retailer is not strategic the dynamic game theoretic model performs better than either benchmark

an alternative explanation for lower repeat rates after promotion purchases several authors have observed that average repeat rates are lower after a promotion purchase one interpretation of this result is that a media coupon or cents off promotion undermines the consumer

shifting endpoints in the term structure of interest rates abstract this paper links the term structure to perceptions of monetary policy long horizon forecasts of short rates required by no arbitrage term structure models are heavily influenced by the endpoints or limiting conditional forecasts of the short rate process common assumptions that the short rate is mean reverting or contains a unit root are shown to generate unrealistic yield predictions failures occur because these assumptions inadequately account for historical shifts in market perceptions of the policy target for inflation this paper links endpoint shifts to agent learning about shifts in long term policy goals shifting endpoints in short rate processes significantly improve yield predictions

regime shifts in a dynamic term structure model of u s treasury bond yields this article develops and empirically implements an arbitrage free dynamic term structure model with priced factor and regime shift risks the risk factors are assumed to follow a discrete time gaussian process and regime shifts are governed by a discrete time markov process with state dependent transition probabilities this model gives closed form solutions for zero coupon bond prices an analytic representation of the likelihood function for bond yields and a natural decomposition of expected excess returns to components corresponding to regime shift and factor risks using monthly data on u s treasury zero coupon bond yields we show a critical role of priced state dependent regime shift risks in capturing the time variations in expected excess returns and document notable differences in the behaviors of the factor risk component of the expected returns across high and low volatility regimes additionally the state dependence of the regime switching probabilities is shown to capture an interesting asymmetry in the cyclical behavior of interest rates the shapes of the term structure of volatility of bond yield changes are also very different across regimes with the well known hump being largely a low volatility regime phenomenon jel g12 this article develops and empirically implements an arbitrage free dynamic term structure model dtsm with priced factor and regimeshift risks the risk factors are assumed to follow a discrete time gaussian process and regime shifts are governed by a discrete time markov process with state dependent transition probabilities agents are assumed to know both the current state of the economy and the regime they are currently in this leads to regime dependent risk neutral pricing and an equilibrium term structure that reflects the risks of both changes in the state and shifts in regimes

a re examination of the predictability of economic activity using the yield spread this paper revisits the yield spread s usefulness for predicting future real gdp growth we show that the contribution of the spread can be decomposed into the effect of expected future changes in short rates and the effect of the term premium we find that both factors are relevant for predicting real gdp growth but the respective contributions differ we investigate whether the cyclical behavior of interest rate volatility could account for either or both effects we find that while volatility displays important correlations with both the term structure of interest rates and gdp it does not appear to account for the yield spread s usefulness for predicting gdp growth

expectation puzzles time varying risk premia and dynamic models of the term structure abstract linear projections of returns on the slope of the yield curve have contradicted the implications of the traditional expectations theory this paper shows that these findings are not puzzling relative to a large class of richer dynamic term structure models specifically we match all the key empirical findings reported by fama and bliss 1987 american economic review 77 4 680 692 and campbell and shiller 1991 review of economic studies 58 495 514 among others within large subclasses of affine and quadratic gaussian term structure models additionally we show that certain risk premium adjusted projections of changes in yields on the slope of the yield curve recover the coefficients of unity predicted by the models key to this matching are parameterizations of the market prices of risk that let the risk factors affect the market prices of risk directly and not only through factor volatilities the risk premiums have a simple form consistent with fama s findings on the predictability of forward rates and are also shown to be consistent with interest rate feedback rules used by a monetary authority in setting monetary policy

reference effects of price and promotion on brand choice behavior when consumers are exposed to pricing and promotional activity by frequently purchased packaged goods they may develop expectations that are used as points of reference in evaluating future activi

a high tech product market share model with customer expectations in a product category based on dynamic technology new products enter the market in rapid succession and the competitive situation changes almost daily because technological features of available products tend to improve while prices tend to decline customers develop expectations that may influence their purchase decisions we model the impact of customer expectations regarding price and technology on product market share in the personal computer industry finding significant nonlinear effects of both these effects are observed when actual product price and or technology differ from expectations by a threshold amount our results suggest implementable implications for high tech product managers in particular price and technology should meet but not exceed customer expectations this does not mean that managers should strive for mediocrity rather continuous improvement should be implemented so that product development efforts lead customer expectations

monetary policy regimes implications for the yield curve and bond pricing abstract we develop a multivariate dynamic term structure model which takes into account the nonlinear time varying relation between interest rates and the state of the economy in contrast to the classical term structure literature in which nonlinearities are captured by increasing the number of latent state variables or by latent regime shifts in our no arbitrage framework the regimes are governed by thresholds and are directly linked to economic fundamentals specifically starting from a simple monetary policy model for the short rate we introduce a parsimonious and tractable model for the yield curve which takes into account the possibility of regime shifts in the behavior of the federal reserve in our empirical analysis we show the merit of our approach three dimensions interpretable bond dynamics accurate short end yield curve pricing and yield curve implications

economic development and the impacts of natural disasters abstract we use disaster impact data over time to examine the degree to which the human and economic losses from natural disasters are reduced as economies develop we find that countries with higher income higher educational attainment greater openness more complete financial systems and smaller government experience fewer losses

testing the expectations hypothesis when interest rates are near integrated nominal interest rates are unlikely to be generated by unit root processes using data on short and long interest rates from eight developed and six emerging economies we test the expectations hypothesis using cointegration methods under the assumption that interest rates are near integrated if the null hypothesis of no cointegration is rejected we then test whether the estimated cointegrating vector is consistent with that suggested by the expectations hypothesis the results show support for cointegration in 10 of the 14 countries we consider and the cointegrating vector is similar across countries however the parameters differ from those suggested by theory we relate our findings to existing literature on the failure of the expectations hypothesis and to the role of term premia

cluster sample methods in applied econometrics inference methods that recognize the clustering of individual observations have been available for more than 25 years brent moulton 1990 caught the attention of economists when he demonstrated the serious biases that can result in estimating the effects of aggregate explanatory variables on individual specific response variables the source of the downward bias in the usual ordinary least squares ols standard errors is the presence of an unobserved state level effect in the error term more recently john pepper 2002 showed how accounting for multi level clustering can have dramatic effects on t statistics while adjusting for clustering is much more common than it was 10 years ago inference methods robust to cluster correlation are not used routinely across all relevant settings in this paper i provide an overview of applications of cluster sample methods both to cluster samples and to panel data sets

roadways input sourcing and patterns of specialization abstract we propose a model where the internal transport network facilitates the sourcing of intermediate goods from geographically diffuse locations a denser internal transport network promotes thus the growth of industries that rely on a large variety of inputs the model shows that heterogeneities in internal transport infrastructures can become a key factor in shaping comparative advantage and specialization evidence based on industry level trade data grants support to the main prediction of the model countries with denser road networks export relatively more in industries that exhibit broader input bases we show that this correlation is robust to several possible confounding effects proposed by the literature such as the impact of institutions on specialization in complex goods furthermore we show that a similar correlation arises as well when the density of the local transport network is measured by the density of their internal waterways and also when road density is instrumented with measures of terrain roughness

the influence of prior beliefs frequency cues and magnitude cues on consumers perceptions of comparative price data a widespread practice in grocery store advertising is to compare the advertised store s prices to a competitor s prices on multiple items an important but largely unexplored issue is how this information is processed and used in conjunction with prior beliefs to influence price perceptions in our initial studies we manipulated prior beliefs and two data based cues frequency of price advantage and magnitude of price advantage to determine their relative influence on consumer price perceptions results indicate that prior beliefs affected price perceptions but that the frequency cue exerted a dominating influence several follow up studies demonstrate the robustness of this phenomenon across a variety of presentational and instructional conditions

the term structure of inflation expectations we use information in the term structure of survey based forecasts of inflation to estimate a factor hidden in the nominal yield curve we construct a model that accommodates forecasts over multiple horizons from multiple surveys and treasury real and nominal yields by allowing for differences between risk neutral subjective and objective probability measures we establish that model based inflation expectations are driven by inflation output and one latent factor we find that this factor affects inflation expectations at all horizons but has almost no effect on the nominal yields that is the latent factor is hidden we show that this hidden factor is not related to either current and past inflation or the standard set of macro variables studied in the literature consistent with the theoretical property of a hidden factor our model outperforms a standard macro finance model in its forecasting of inflation and yields

real risk inflation risk and the term structure i present a model for the term structures of nominal and real interest rates in the uk that incorporates markov switching and allows for non neutralities nonlinear dynamics and flexibility in the dynamics of the risk premia the model is used to assess how accurately the term structure reflects changing expectations of future yields and inflation i find that variations in inflation expected over the next two to three years are very accurately reflected by current yields over longer horizons the term structures closely track changing expectations regarding future nominal and real yields but not future inflation

a model of balanced choice behavior in some product categories consumers appear to alternate among items in a consistent and purposeful though not entirely deterministic fashion such alternation occurs even in the absence of any apparent external influences on choice to explain such balanced choice behavior we present a model based upon the premise that past consumption influences the utility of items on subsequent choice occasions individuals may seek variety on certain product attributes and exhibit loyalty toward others the model specification yields a logit choice model which may be calibrated using consumption diary panel data at the individual or cross sectional level

term structure views of monetary policy under alternative models of agent expectations abstract term structure models and many descriptions of the transmission of monetary policy rest on the empirical relevance of the expectations hypothesis small differences in the perceived policy reaction function in var models of agent expectations strongly influence the relevance in the transmission mechanism of the expected short rate component of bond yields mean reverting or difference stationary characterizations of interest rates require large and volatile term premiums to match the observable term structure however short rate descriptions that capture shifting perceptions of long horizon inflation evident in survey data support a more substantial term structure role for short rate expectations

hysteresis price acceptance and reference prices the existence of price thresholds in grocery retailing is well documented most authors explain the existence of price thresholds using assimilation contrast theory adaptation level theory or prospect theory however each of these theories is untenable if consumers are believed to behave rationally we offer a theoretical explanation grounded in real options theory rot and economic hysteresis we test the rot hypothesis against three plausible alternatives using a maximum likelihood friction model that we augment for unobserved heterogeneity our findings support the rot hypothesis and suggest that the existence of price thresholds in aggregate data are driven by a common recognition of real option values which do not disappear with the inclusion of consumer heterogeneity

the volatility of long term bond returns persistent interest shocks and time varying risk premiums we develop an almost affine term structure model with a closed form solution for factor loadings in which the spot rate and the risk price are fractionally integrated processes with different integration orders this model is used to explain two stylized facts first predictability of longterm excess bond returns requires sufficient volatility and persistence in the risk price second the large volatility of long term bond returns requires persistence in the spot rate decomposing long term bond returns we find that the expectations component from the level factor is more volatile than returns themselves and that the risk premium correlates negatively with level factor innovations

brand loyalty and market equilibrium two concepts of brand loyalty are defined inertial brand loyalty resulting from time lags in awareness and cost based brand loyalty resulting from intertemporal utility effects their market level implications are formally derived in a continuous time model it is found that inertial brand loyalty leads to equilibria with price dispersion while cost based brand loyalty also may allow single price equilibria in all cases as brand loyalty vanishes so does the difference between the average trading price and the price which obtains with no brand loyalty consistent with empirical results the theory predicts that the relationship between market share and performance is positive in cross sectional studies but flat in time series studies the theory is also consistent with the view that market share is an asset in itself after developing the theory several strategic implications are drawn in the end some questions for further theoretical and empirical research are raised

understanding reference price shoppers a within and cross category analysis abstract the authors attempt to draw profiles of reference price shoppers specifically the authors study how selected factors that affect brand choice are correlated with consumer sensitivity to gains and losses with respect to internal reference prices they also study the interaction between sociodemographics and gain and loss sensitivity furthermore the authors analyze cross category correlations in gain and loss sensitivity to shed light on their individual and category specific characters in three categories the results show significant heterogeneity in loss sensitivity among consumers and indicate that loss sensitivity is greater and more heterogeneous than gain sensitivity across categories the results show that loss sensitive shoppers are less influenced by past brand use and that both loss and gain sensitive shoppers more sensitive to price display and feature than the average consumer loss sensitive households tend to be larger and their heads are less likely to be fully employed

extracting inflation expectations and inflation risk premia from the term structure a joint model of the uk nominal and real yield curves abstract this paper analyses the uk interest rate term structure over the period since october 1992 when the united kingdom adopted an explicit inflation target using an affine term structure model estimated using both government bond yields and survey data the model imposes no arbitrage restrictions across nominal and real yields which enables interest rates to be decomposed into expected real policy rates expected inflation real term premia and inflation risk premia the model is used to shed light on major developments over the period including the impact of bank of england independence and the low real bond yield conundrum
