decomposing promotional effects with a dynamic structural model of flexible consumption abstract in this article the authors offer a methodology to decompose the effects of price promotions into brand switching stockpiling and change in consumption by explicitly allowing for consumer heterogeneity in brand preferences and consumption needs they develop a dynamic structural model of a household that decides when what and how much to buy as well as how much to consume to maximize its expected utility over an infinite horizon by making certain simplifying assumptions the authors reduce the dimensionality of the problem they estimate the proposed model using household purchase data in the canned tuna and paper towels categories the results from the model offer insights into the decomposition of promotional effects into its components this could help managers make inferences about which brand s sales are more responsive to stockpiling or increase in consumption expansion and how temporary price cuts affect future sales contrary to previous literature the authors find that brand swi

inflation level and inflation volatility a seigniorage argument abstract we use a standard dynamic general equilibrium model with flexible prices money in the utility function exogenous fiscal policy and accommodating monetary policy to analytically demonstrate the positive relationship between the steady state level of inflation and business cycle inflation volatility this result holds in the presence of unique as well as multiple equilibria

do switching costs make markets less competitive abstract the conventional wisdom in economic theory holds that switching costs make markets less competitive this article challenges this claim the authors formulate an empirically realistic model of dynamic price competition that allows for differentiated products and imperfect lock in they calibrate this model with data from frequently purchased packaged goods markets these data are ideal in the sense that they have the necessary variation to identify switching costs separately from consumer heterogeneity equally important consumers exhibit inertia in their brand choices a form of psychological switching cost this makes the results applicable to the broad range of products that are distinctly identified i e branded rather than just to products for which there is a product adoption cost or explicit switching fee in the simulations prices are as much as 18 lower with than without switching costs more important equilibrium prices do not increase even in the presence of switching costs that

please or squeeze brand performance implications of constrained and unconstrained multi item promotions existing research on price promotions typically investigates the effects of single product promotions however brand managers often promote multiple items simultaneously to bolster the performance of a complete brand line this paper investigates the brand performance implications of such multi item promotions we distinguish between two types of multi item promotions traditional unconstrained multi item promotions that grant a discount irrespective of the size or composition of the purchase set and constrained multi item promotions that require consumers to purchase specific quantities self bundling or even predetermined combinations fixed bundling of promoted items using a normative consumer decision model the authors analyze the relative effectiveness of these promotions in terms of unit sales and revenue impact and show that promotion performance is moderated by consumers preference for variety the authors find that unconstrained multi item promotions outperform single item promotions especially in markets without variety seeking in markets with variety seeking unconstrained multi item promotions are not as effective in stealing extra sales from competition because consumers prefer to spread their purchases across all items including competitive ones however in those markets self bundling promotions are particularly effective because they force consumers to adopt larger amounts of the promoted items at the expense of competitors finally in neither type of market does fixed bundling substantially improve promotion performance

does inflation targeting improve fiscal discipline abstract we explore the performances of inflation targeting it adoption in terms of fiscal discipline fd while most existing studies focus exclusively on the role of fd as a precondition for it adoption using a sample of developing and developed countries we show that it adoption exerts a positive and significant effect on fd a result robust to a wide variety of alternative specifications in addition this effect is statistically significant only in developing countries a result that may fuel the current debate regarding the relevance of it adoption in general and particularly for developing countries

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

credit to government and banking sector performance abstract the impact of credit to government on three aspects of banking sector performance its deepening over time profitability and efficiency is examined for 142 countries country regressions suggest a sizeable negative effect of credit to government on bank deepening in developing countries but no impact in advanced economies bank regressions find that credit to government raises the profitability but reduces the efficiency of banks in developing countries in advanced economies there appears to be no impact on profitability but a positive one on efficiency

on the low frequency relationship between public deficits and inflation summary we estimate the low frequency relationship between fiscal deficits and inflation and pay special attention to its potential time variation by estimating a time varying vector autoregression model for us data from 1900 to 2011 we find the strongest relationship neither in times of crisis nor in times of high public deficits but from the mid 1960s up to 1980 employing a structural decomposition of the low frequency relationship and further narrative evidence we interpret our results such that the low frequency relationship between fiscal deficits and inflation is strongly related to the conduct of monetary policy and its interaction with fiscal policy after world war ii copyright 2015 john wiley sons ltd

fiscal deficits and inflation abstract macroeconomic theory postulates that persistent fiscal deficits are inflationary yet empirical research has had limited success in uncovering this relationship this paper reexamines the issue in light of broader data and a new modeling approach that incorporates two key features of the theory unlike previous studies we model inflation as non linearly related to fiscal deficits through the inflation tax base and estimate this relationship as intrinsically dynamic using panel techniques that explicitly distinguish between short and long run effects of fiscal deficits results spanning 107 countries over 1960 2001 show a strong positive association between deficits and inflation among high inflation and developing country groups but not among low inflation advanced economies

the asymmetric information model of state dependence marketing researchers and practitioners are interested in consumer loyalty because of its managerial consequences previous empirical studies find that consumers are loyal not only to a brand but also to a firm umbrella brand that is even when firms offer new products consumers tend to continue to purchase from the same firm this repeat purchase behavior might result from state dependence or from heterogeneity the meaning of state dependence is that the current choice behaviorally depends on the previous one the traditional model of state dependence assumes that the previous choice affects the current utility this study suggests another source of state dependence the previous choice affects the current information set specifically the model assumes that the consumer a knows the attributes of the new product offered by the firm from which he she purchased in the previous period b is uncertain about the attributes of the new products offered by the other firms c can obtain full information about the attributes of all the products through a costly search and d if the consumer decides not to search he she purchases the new product offered by the firm from which he she purchases in the previous period it is shown that state dependence can result either from the effect of previous choices on the current utility or from its effect on the current information set this theoretical result raises the following question what kind of data does a researcher need in order to distinguish between the two sources of state dependence this study shows that the two sources can be distinguished with a standard panel data set in other words although the new source of state dependence is based on the search activity of consumers there is an identifying factor that enables a researcher to detect such activity even without direct data on search the empirical distinction is possible because the behavioral implications of the two sources of state dependence are different they differ in the effect of product attributes on the repeat purchase probability the following example partially illustrates this result there are two firms a and b the consumer purchased a product from firm a in period t 1 the only product attribute is x and the utility is a linear function of x one aspect of our findings is that in the traditional model of state dependence a change in both x a and x b that leaves the difference between them x a x b unchanged neutral change hereinafter has no effect on the repeat purchase probability however such a change does affect the repeat purchase probability in the asymmetric information model of state dependence this is only one aspect of the finding the implications of the models differ in a more general fashion the intuition of this result is the following a neutral change has no effect on the repeat purchase probability in the traditional model of state dependence because it does not affect the difference between the utilities from both alternatives in the asymmetric model of state dependence the consumer s decision process consists of two stages first he decides whether to search for information about the other alternative or not then if he searches for information he chooses the alternative that maximizes his utility in the second stage a neutral change has no effect on choices since such a change does not affect the difference between the utilities from the two alternatives in the first stage the consumer knows x a but does not know x b it turns out that in this stage a neutral change does affect the search decision when for example both x s decrease and the utility is a positive function of x the probability of search increases and thus the repeat purchase probability decreases the proposed source of state dependence is examined using structural estimation and panel data on television viewing choices in the united states controlling for both observed and unobserved heterogeneity it is found that the suggested source is more important in creating repeat purchase than the traditional one for most of the population 71 this indicates that what was considered by previous studies to result from the dependence of consumer utility on their previous choices is at least partially due to the effect of the previous choices on consumers information set the distinction between the two sources of repeat purchase is important because ignoring the informational explanation may lead to incorrect theoretical and empirical conclusions for example price discounts to induce trial are more important for consumers whose utility depends on previous choices while advertising is more effective for those whose information set depends on previous choices

on the recoverability of choice behaviors with random coefficients choice models in the context of limited data and unobserved effects random coefficients choice models are seeing widespread adoption in marketing research partly because of their ability to generate household level parameter estimates with limited data however the power of such models may tempt researchers to trust that they continue to produce reasonable estimates when in fact either model misspecification or insufficient data limits the models ability to recover household level parameters successfully if household level choice behaviors are not recovered successfully managerial decisions such as marketing mix planning and targeting direct marketing segmentation and forecasting may not produce the desired results this study addresses the following questions first can random coefficients choice models correctly identify markets characterized by preference and response heterogeneity state dependence the use of alternative decision heuristics that result in reduced choice sets and combinations of these effects if so how much data is required and is this realistic given the size of data sets typically used in marketing analyses which model selection criteria should be used to identify these markets when there is spurious market identification which parameters contribute to the spurious result an extensive simulation experiment is conducted wherein random coefficients logit models with varying specifications of parameter heterogeneity state dependence effects and choice set heterogeneity are applied to 128 experimental conditions the results show which types of markets can be identified reliably and which cannot based on the results of the simulation the authors develop a model selection heuristic that identifies the correct market in 81 of the experimental conditions in contrast strict application of the best model selection criterion alone results in correct market identification in at most 34 of experimental conditions interestingly we find that the amount of data number of households or number of purchases per household does not affect our ability to identify the correct market type with this heuristic so there is a good chance of identifying the correct market type even when little data is available

openness and inflation a new assessment romer 1993 uses a barro gordon type model to argue that openness puts a check on the government s incentive to engage in unanticipated inflation because of induced exchange rate depreciation 2 therefore in the absence of precommitment in monetary policy more open economies will tend to have lower inflation rates romer finds that empirically over a large sample of countries and over a broad time frame average inflation rates are lower in smaller more open economies this relationship is significant quantitatively large and robust moreover these findings suggest that models in which the absence of precommitment in monetary policy leads to inefficiently high average levels of inflation are essential to understanding inflation in most of the world this comment suggests that the negative link between inflation and openness romer found may be largely driven by the responses of severely indebted countries sics to the debt crisis of the 1980s figures i and ii show the scatterplots of the logarithms of average inflation and openness for the subperiods 1973 to 1981 predebt crisis and 1982 to 1990 the debt crisis period different groups of countries are separated according to their indebtedness level 3 the solid lines in the figures represent the predicted value of inflation obtained from a regression of openness on inflation for the countries in each group as the scatterplots show there is indeed a strong negative relation between openness and inflation among sics during the debt crisis

are financial development and trade openness complements or substitutes this article studies the long and short run relationships between financial development and trade openness using the pooled mean group estimator of pesaran shin and smith 1999 for unbalanced panel data for 87 countries over the 1960 2005 period our empirical results indicate that long run complementarity between financial development and trade openness coexists with short run substitutionarity between the two policy variables but when splitting the data into oecd and non oecd country groups this finding can be observed only in non oecd countries for oecd countries financial development has negligible effects on trade in addition we find nonlinearity in the relationship in that long run responses of trade decrease with financial development the article further finds coexistence of negative trade effects of financial fragility and positive trade impacts of financial depth

commentary on the interpretation of temporal inflation parameters in stochastic models of judgment and choice the implications of salisbury and feinberg s 2010 paper salisbury l c f m feinberg 2010 alleviating the constant stochastic variance assumption in decision research theory measurement and experimental test marketing sci 29 1 1 17 for the process of model development and testing in the field of intertemporal choice analysis is explored although supporting the overall thrust of salisbury and feinberg s critique of previous empirical work in the area we also see their paper as illustrating the dangers of drawing strong inferences about the behavioral interpretation of statistical model parameters without seeking convergent empirical evidence in particular we are skeptical about the extent to which the reported effects of temporal distance on the estimated scale parameter c are uniquely or even primarily due to unobserved error inflation that reflects consumer s uncertainty about future utility this interpretation is brought into question by several lines of reasoning conceptually we note that uncertainty is different from error and that for choice data the error inflation model is mathematically identical to a model in which the scale parameter is a deterministic function of the temporal discount rate empirically a reanalysis of data from previously published experiments does not consistently support temporal error inflation temporal convergence of choice shares or the scale parameter as an explanation of variety seeking in choice sequences in our opinion the cumulative results of research on intertemporal choice require models in which the attributes of choice alternatives are differentially discounted over time despite these findings we advocate that choice researchers should indeed follow salisbury and feinberg s advice to not assume that error variances will be unaffected by experimental manipulations and such effects should be explicitly modeled we also agree that uncovering effects on error variance is just the first step and the ultimate goal should be to rigorously explain the reasons for such effects

a model of stochastic variety seeking in this paper we propose and test a stochastic model of consumer choice that incorporates attribute based variety seeking our stochastic variety seeking model svs has nested within it a fixed variety seeking model a zero order model of choice and a first order pure variety model we compare the svs model to alternative models under stochastic variety seeking we examine the nature of the variety sought and provide a test of the satiation hypothesis unlike fixed variety seeking models our model allows variety seeking to vary in intensity and consistency over individuals as well as over purchase occasions we show that the model is equivalent to a random utility model with the features that the attributes of brands relative to those of the brand previously bought influence choice and the extent of variety seeking is random over choice occasions for a given individual the model permits a closed form solution to the conditional switching probabilities parameterized by variety seeking parameters and dependent on brand attributes we apply our model to individual choice data obtained from a field study specifically designed for the purpose at hand

anchoring inflation expectations in the face of oil shocks in the proximity of zlb a tale of two targeters this paper applies a n ardl framework to two longstanding inflation targeting policy regimes in order to assess the relation between oil prices dynamics and inflation expectations and the further consequences created by a proximal zlb situation the application is based on data from january 1994 to june 2018 for new zealand and the uk we focus on oil price shocks as a variable of interest and this was found to have an asymmetric effect on inflation expectations one further key finding is that the real effective exchange rate has significant impacts on inflation expectations and this is indicative of an exchange rate pass through to inflation via an inflation expectations channel in general we find that inflation exchange rate money supply output growth unemployment and fiscal deficit surplus have significant implications for inflation expectations inflation expectations are also influenced by their past behaviour indicating adaptive inflation expectations this study contributes to the debate on the inflation targeting at zlb

speed of replacement modeling brand loyalty using last move data abstract the authors study brand loyalties for durable goods using automobile survey data that are peculiarly censored and track only elapsed times since transitions but not the transition times themselves this censoring problem is typical of commercially available durable goods survey data however little attention has been paid to such last move data in the statistics or marketing literature on the analysis of transition times the authors propose a multistate continuous time nonstationary markov model with a parsimonious brand loyalty structure and also propose an estimation approach to recover the parameters of the proposed model using the automobile survey data the proposed model fits observed brand choice outcomes even better than a model with a fully unrestricted and therefore highly parameterized transition structure the authors also obtain several substantive findings for example chrysler is significantly weaker than general motors and ford insofar as it has the lowest brand loyal

fiscal reforms and stabilisation four hyperinflation cases examined this paper discusses a hypothesis that is common to several recent explanations for the needs of hyperinflations of the 1920s namely that fiscal reforms had been responsible for their sudden end it is suggested that the very presence of these reforms can be disputed once evidence is provided on the fact that budget deficits were mostly caused by the so called oliveira tanzi effect i e deficits were mostly generated by inflation itself some observations are offered on other issues to be addressed if an alternative explanation for the stabilizations are to be found copyright 1990 by royal economic society

seigniorage in a cross section of countries empirical investigation of the average level of seigniorage in a cross section of up to ninety countries for the period 1971 90 suggests that optimum tax theory explains up to 40 percent of the cross country variation in seigniorage since seigniorage is higher where its deadweight losses are probably lower and where deadweight losses from conventional taxation are probably higher but that average government spending is not a determinant of seigniorage practical concerns about financing transitory government spending explain some of the remaining variation in seigniorage and central bank independence and political instability are useful as well in contrast 90 percent of the cross country variation in conventional taxation appears to be determined by the level of government spending and deadweight losses and additional variables do not add to the results

the overvaluation of purchasing power parity abstract recent panel studies of purchasing power parity have reported strong evidence of mean reversion in real exchange rates however these studies fail to control for cross sectional dependence in the data this failure has dramatic consequences raising the significance level of tests with a nominal size of 5 percent to as much as 50 percent it is shown in this paper that controlling for cross sectional dependence no evidence against the random walk null can be found in panels of up to 64 real exchange rates this finding cannot be attributed to low power as there is ample power in panels of this size to reject the unit root null

are food choices really habitual integrating habits variety seeking and compensatory choice in a utility maximizing framework given the large number of food choices that consumers make each day it seems likely that they will adopt decision strategies that minimize cognitive effort to examine this issue we develop a conceptual and empirical model of habitual choice and the factors that result in transitions to two strategies other than habitual selection utility maximizing choice and a variety seeking strategy our approach provides an alternative to traditional state dependence methods used in this type of panel data we apply this framework to the choice of two food products that illustrate the heterogeneity across types of products in decision strategies and routine choice patterns copyright 2013 oxford university press

the dynamic effect of discounting on sales empirical analysis and normative pricing implications baseline sales measure what retail sales would be in the absence of a promotion abraham and lodish 1993 and models that measure baseline sales are widely used by managers to assess the profitability of promotions bucklin and gupta 1999 this issue estimates of baseline sales and promotional response are typically independent of past promotional activity even though there is evidence to suggest that increased discounting reduces off promotion sales and increases the percentage of purchases made on deal e g krishna 1994 as a result models that do not consider dynamic promotional effects can mislead managers to overpromote given the widespread use of static models to evaluate the efficacy of promotions it is particularly desirable to calibrate a dynamic brand sales model and use it to establish an optimal course of action accordingly we develop a descriptive dynamic brand sales model and use it to determine normative price promotion strategies our descriptive approach consists of estimating a varying parameter sales response model letting model parameters vary with past discounting activity accommodates the possibility that market response changes with firms discounting policies in the normative model we use the estimates obtained in the descriptive model to determine optimal retailer and manufacturer prices over time the results of the descriptive model indicate that promotions have positive contemporaneous effects on sales accompanied by negative future effects on baseline sales the results of the normative model suggest that the higher share brands in our data tend to overpromote while the lower share brands do not promote frequently enough we project that the use of our model could improve manufacturers profits by as much as 7 to 31 more generally the normative results indicate that i if deals become more effective in the current period i e if consumers are more price sensitive promotions should be used more frequently and ii as the negative dynamic effect of discounts on sales increases the optimal level of discounting should go down without our approach it would be difficult to make this trade off exact finally we demonstrate that these dynamic effects provide another perspective to the marketing literature regarding the existence of promotions

investigating heterogeneity in brand preferences in logit models for panel data in analyzing panel data the issue of heterogeneity across households is an important consideration if heterogeneity is present but is ignored in the analysis it will result in biased and inconsi

removing heterogeneity bias from logit model estimation this paper introduces a new estimation procedure for the logit model that is an extension of a conditional estimation procedure developed by chamberlain chamberlain g 1978 on the use of panel data working paper harvard university 1 52 chamberlain g 1980 analysis of covariance with qualitative data rev econom stud 47 225 238 the method eliminates heterogeneity bias which is present in the estimates produced by traditional estimation techniques it improves the goodness of fit and explanatory power of these models while incorporating purchase event feedback

all things considered the role of choice set formation in diversification abstract the diversification effect a tendency toward greater variety as multiple choices are made simultaneously in advance of consumption is a robust and important phenomenon researchers have typically explained the diversification effect in terms of differences in the process by which people select items from among those available this precludes the possibility that the locus of the effect lies in people s choice sets themselves that is how people decide which options to consider when making choices the authors examine the effects of set formation using an experimental choice sequence task and conjoined stochastic model of set formation and conditional choice the findings demonstrate that set formation plays a critical role in diversification previously chosen options are indeed discounted but only for simultaneous choices and only in the set formation portion of the model furthermore the expected number of choice set items is substantially greater in multiple versus single item choice s

why are stabilizations delayed when a stabilization has significant distributional implications e g tax increases to eliminate a large budget deficit socioeconomic groups may attempt to shift the burden of stabilization onto other groups the process leading to stabilization becomes a war of attrition each group attempting to wait the others out and stabilization occurring only when one group concedes and bears a disproportionate share of the burden the authors solve for the expected time of stabilization in a model of rational delay and relate it to several political and economic variables they motivate this approach and its results by comparison to historical and current episodes copyright 1991 by american economic association

modeling multiple sources of state dependence in random utility models a distributed lag approach we propose a utility theoretic brand choice model that accounts for four different sources of state dependence 1 effects of lagged choices structural state dependence 2 effects of serially correlated error terms in the random utility function habit persistence type 1 3 effects of serial correlations between utility maximizing alternatives on successive purchase occasions of a household habit persistence type 2 and 4 effects of lagged marketing variables carryover effects our proposed model also allows habit persistence to be a function of lagged marketing variables while accommodating the effects of unobserved heterogeneity in household choice parameters this model is more flexible than existing state dependence models in marketing and labor econometrics using scanner panel data we find structural state dependence to be the most important source of state dependence marketing mix elasticities are systematically understated if state dependence effects are incompletely accounted for the seetharaman and chintagunta 1998 model is shown to recover spurious variety seeking effects while overstating habit persistence effects ignoring habit persistence type 1 leads to an underestimation while ignoring habit persistence type 2 leads to an overestimation of structural state dependence effects we find lagged promotions to have carryover effects on habit persistence ignoring one or more sources of state dependence underestimates the total incremental impact of a sales promotion we draw implications for manufacturer pricing

category pricing with state dependent utility there is substantial literature documenting the presence of state dependent utility with packaged goods data typically a form of brand loyalty is detected whereby there is a higher probability of purchasing the same brand as has been purchased in the recent past the economic significance of the measured loyalty remains an open question we consider the category pricing problem and demonstrate that the presence of loyalty materially affects optimal pricing the prices of higher quality products decline relative to those of lower quality when loyalty is introduced into the model given the well known problems with the confounding of state dependence and consumer heterogeneity loyalty must be measured in a model which allows for an unknown and possibly highly nonnormal distribution of heterogeneity we implement a highly flexible model of heterogeneity using multivariate mixtures of normals in a hierarchical choice model we use an euler equations approach to the solution of the dynamic pricing problem which allows us to consider a very large number of consumer types

energy growth conundrum in energy exporting and importing countries evidence from heterogeneous panel methods robust to cross sectional dependence abstract this article uses the panel methods for energy exporting and importing countries that discuss the heterogeneity and cross sectional dependence in investigating the linkages between energy consumption and economic growth the findings of the study suggest that the energy consumption is an important input not only in the energy importing but also in energy exporting countries furthermore the results of the present paper suggest that the policy options should be different for the different countries in the back drop of heterogeneous slope coefficients

seigniorage and political instability the importance of seigniorage relative to other sources of government revenue differs markedly across countries this paper tries to explain this regularity by studying a political model of tax reform the model implies that countries with a more unstable and polarized political system will have more inefficient tax structures and thus will rely more heavily on seigniorage this prediction of the model is tested on cross sectional data for seventy countries the authors find that after controlling for other variables political instability is positively associated with seigniorage copyright 1992 by american economic association

budget deficits and interest rates a fresh perspective we extend the literature on budget deficits and interest rates in three ways we examine both advanced and emerging economies and for the first time a large emerging market panel explore interactions to explain some of the heterogeneity in the literature and apply system gmm there is overall a highly significant positive effect of budget deficits on interest rates but the effect depends on interaction terms and is only significant under one of several conditions deficits are high mostly domestically financed or interact with high domestic debt financial openness is low interest rates are liberalized or financial depth is low

state dependence and alternative explanations for consumer inertia for many consumer packaged goods products researchers have documented inertia in brand choice a form of persistence whereby consumers have a higher probability of choosing a product that they have purchased in the past using data on margarine and refrigerated orange juice purchases we show that the finding of inertia is robust to flexible controls for preference heterogeneity and not due to autocorrelated taste shocks thus the inertia is at least partly due to structural not spurious state dependence we explore three economic explanations for the observed structural state dependence preference changes due to past purchases or consumption experiences which induce a form of loyalty search and learning our data are consistent with loyalty but not with search or learning properly distinguishing among the dierent sources of inertia is important for policy analysis because the alternative sources of inertia imply qualitative dierences in firm s pricing incentives and lead to quantitatively dierent equilibrium

testing for choice dynamics in panel data this article applies different approaches to distinguish state dependence from unobserved heterogeneity and serial correlation and hence test for state dependence in consumer brand choices first we apply a simple method proposed by chamberlain which involves lagged exogenous variables only second we also estimate a lagged dependent variable specification proposed by wooldridge third we use the estimation approach suggested by wooldridge to estimate a model with both lagged dependent and exogenous variables to distinguish between the two different sources of choice dynamics state dependence and lagged effects of the exogenous variables our analysis reveals that the best approach is to use models with both lagged dependent and exogenous variables our findings include strong evidence for state dependence in five out of the six product categories studied in this article

public debt and financial development abstract we examine the role of public debt in financial development the literature has highlighted its supportive role through providing collateral and benchmark we contrast this safe asset view to a lazy banks view developing banking sectors that lend mainly to the public sector may develop more slowly because it could make banks profitable but inefficient results from country level and bank level regressions are more supportive of the lazy banks view but the safe asset view seems to play a role at moderate levels of public debt held by banks there is also evidence of a harmful interaction between public debt and financial repression

parameter bias from unobserved effects in the multinomial logit model of consumer choice abstract over the past two decades validation of choice models has focused on predictive validity rather than parameter bias in real world validation of choice models true parameter values are unknown so examination of parameter bias is not possible in contrast the main focus of this study is parameter bias in simulated scanner panel choice data with known parameter values study of parameter bias enables the assessment of a fundamental issue not addressed in the choice modeling literature the extent to which the logit choice model is capable of distinguishing unobserved effects that give rise to persistence in observed choices e g heterogeneity and state dependence although econometric theory provides some information about the causes of bias the extent of such bias in typical scanner data applications remains unclear the authors present an extensive simulation study that provides information on the extent of bias resulting from the misspecification of four unobserved effects that receive fr

assessing the fiscal stance in the european union and the united states 1970 2011 the huge increases in debt gdp ratios following the 2007 2009 global financial crisis which are unprecedented except in times of war has focused attention on the viability of the fiscal positions of eu countries and the us how to assess this and the likely future evolution of these positions this paper proposes an indicator of the fiscal stance which computes the fiscal adjustment required to reach a specific debt gdp targeted given the forecasts of future deficit and interest rates obtained from an unrestricted recursively estimated var model the index is easy to compute and can be decomposed to disclose the different contribution of revenue expenditure nominal yields inflation and growth to the fiscal stance for this reason it provides a transparent and detailed measure of the fiscal stance particularly suitable for multi country surveillance as a result the index improves on the tax gap indicators widely used by governments and international agencies and is far more informative than formal econometric tests of fiscal sustainability the time series of the indicator for individual eu countries and the us show that their fiscal position has fluctuated considerably over the last 40 years and has particularly deteriorated since 2007 the index predicts that the adjustment required to restore pre crisis debt gdp levels are higher for high debt countries like greece italy and portugal they become more severe the shorter is the time horizon for the adjustment as a large degree of uncertainty surrounds the assessment of the fiscal stance in the medium and long run we argue that policy makers should inform their policy based on the worst case scenario predicted by the indicator

inflation and real stock returns revisited i introduction this article empirically reinvestigates the relationship between real stock returns and inflation according to fisher 1930 1 in an efficient market real stock returns should reflect expectations only about real factors such as growth in output and time preference of savers such that real stock returns and inflation should vary independently in other words on average investors are fully compensated for erosions in purchasing power over time however this so called generalized fisher hypothesis has received little empirical support while kaul 1990 boudoukh and richardson 1993 solnik and solnik 1997 madsen 2005 and ryan 2006 find positive or weakly positive correlation between stock returns and inflation most empirical studies including nelson 1976 fama 1981 1983 geske and roll 1983 gultekin 1983 kaul 1987 and solnik 1983 uncover a negative effect of inflation anticipated and or unanticipated on real or nominal stock returns these apparent inconsistencies between the data and the predictions of economic theory have been termed as the stock return inflation puzzle and cited as evidence of monetary nonsuperneutrality or irrationality and market inefficiency 2 to reconcile the seemingly conflicting contributions danthine and donaldson 1986 provide a rational expectations equilibrium model in which a negative relation between stock returns and inflation arises from non monetary sources e g a real output shock and a positive relation is driven by purely monetary sources stulz 1986 marshall 1992 and bakshi and chen 1996 also assert that stock returns may be negatively correlated with inflation especially when the source of inflation is related to nonmonetary factors evidently hess and lee 1999 khil and lee 2000 and lee 2003 find that while monetary shocks drive a positive correlation real fiscal or real output shocks result in a negative correlation between stock returns and inflation from a different perspective kaul 1987 1990 argues that the relation between these two variables depends on both the money demand and the money supply specifically while the combination of money demand effects with a countercyclical monetary response accentuates a negative correlation money demand shocks along with a procyclical monetary response lead to a neutral or positive correlation between real stock returns and inflation similar arguments can be found in day 1984 kaul and seyhun 1990 boudoukh richardson and whitelaw 1994 and gallagher and taylor 2002 and are supported by compelling empirical evidence see e g kim 2003 lee 1992 as an alternative this article models the real stock return inflation relationship as intrinsically dynamic explicitly distinguishing between the short run and the long run such a distinction is crucial because imperfect information rigidity and or contractual obligations are more prevalent in the short run than in the long run in that sense the response of real stock returns to inflation could differ in the short run versus long run moreover we assess the long and short run impacts of inflation uncertainty on real stock returns as argued the real costs of inflation are associated with its uncertainty greater inflation uncertainty resulting from higher inflation may lead to economic inefficiency lower real investment and unemployment thereby reducing economic growth thus it is interesting to see if there are independent effects of inflation uncertainty on real stock returns both in the short run and in the long run in so doing this article uses an innovative econometric technique to explore the long and short run relationships between real stock returns and inflation both anticipated and unanticipated and the relationships with inflation uncertainty it departs from earlier work and complements recent evidence in at least three aspects

try it you will like it does consumer learning lead to competitive price promotions there is strong evidence that consumers learn from their brand consumption experiences and continuously update their brand purchase probabilities however in explaining why established competitive brands continuously compete through periodic price promotions most of the existing theories do not attribute this phenomenon to underlying consumer learning yet try it you will like it is often the stated rationale of the practicing marketing manager in offering consumers a price promotion on a brand this paper examines the connection between consumer learning and the offering of price promotions the consumer model specified is markovian in nature and encompasses in addition to consumer learning other empirical findings such as the increase in product class consumption in response to price reductions the consumer models used in the existing game theoretic approaches to this problem are shown to be mostly special cases of the proposed model it is demonstrated that for the commonly used price response functions the existence of consumer learning at a level of intensity consistent with that identified in empirical works makes it optimal for competing brands to periodically offer price promotions moreover it is shown that the competing brands should promote in different periods as opposed to head to head

fiscal requirements for price stability maintaining price stability requires not only commitment to an appropriate monetary policy rule but an appropriate scal policy rule as well ricardian equivalence does not imply that scal policy is irrelevant except in the case of a certain class of policies ricardian policies the role of scal developments in inflation determination under a non ricardian regime is illustrated through an analysis of the bond price support regime of the 1940s a monetary scal regime with attractive properties would combine a taylor rule for monetary policy with nominal decit targeting as a scal policy commitment

alleviating the constant stochastic variance assumption in decision research theory measurement and experimental test analysts often rely on methods that presume constant stochastic variance even though its degree can differ markedly across experimental and field settings this reliance can lead to misestimation of effect sizes or unjustified theoretical or behavioral inferences classic utility based discrete choice theory makes sharp testable predictions about how observed choice patterns should change when stochastic variance differs across items brands or conditions we derive and examine the implications of assuming constant stochastic variance for choices made under different conditions or at different times in particular whether substantive effects can arise purely as artifacts these implications are tested via an experiment designed to isolate the effects of stochastic variation in choice behavior results strongly suggest that the stochastic component should be carefully modeled to differ across both available brands and temporal conditions and that its variance may be relatively greater for choices made for the future the experimental design controls for several alternative mechanisms e g flexibility seeking and a series of related models suggest that several econometrically detectable explanations like correlated error state dependence and variety seeking add no explanatory power a series of simulations argues for appropriate flexibility in discrete choice specification when attempting to detect temporal stochastic inflation effects

a dynamic analysis of market structure based on panel data internal market structure analysis infers brand positions in an attribute space from preference and choice data given a market in which consumers have heterogeneous tastes for attributes previous market structure models have adopted a static framework e g elrod 1988 chintagunta 1994 elrod and keane 1995 furthermore they assumed that consumer perceptions of brand attributes do not vary across consumers yet these approaches may render inaccurate representations of market structure if there is state dependence in consumer choice behavior this paper attempts to incorporate consumer choice dynamics into market structure models by specifying the source of choice dynamics explicitly in particular the process by which past purchases affect current choices is modeled in a framework which captures both consumer habit persistence and variety seeking behavior more specifically consumer preferences for brand attributes are modeled to depend on the attributes of brands bought on the previous purchase occasion furthermore the modeling approach adopted incorporates heterogeneity in both consumer preferences and perceptions of brand attributes the audience of this paper includes practitioners and academics interested in understanding consumer choice processes and inferring market structure from consumer choice data the proposed models are estimated on nielsen scanner panel data for margarine peanut butter yogurt and liquid detergent using simulated maximum likelihood techniques the empirical results suggest that accounting for choice dynamics improves both in sample and out of sample fit the results indicate that the average consumer is habit persistent in all the product categories studied this result is consistent with the findings of kannan and sanchez 1994 who conducted an aggregate analysis of consumer variety seeking behavior across product categories however the results obtained in this paper suggest that consumers are heterogeneous with respect to the processes by which past purchases affect current purchases these results provide strong evidence for habit persistence and variety seeking in brand attributes to be the behavioral source of consumer choice dynamics in food categories thus consumer tastes utility weights seem to be affected by the attributes of the brands consumed in the past given the empirical result that a large proportion of consumers are habit persistent this suggests that tastes are reinforced by the brand attributes consumed in the past the empirical results also show that not accounting for state dependence in market structure models for panel data may produce misleading results that is depending on consumer behavior patterns models that do not account for state dependence may distort the true nature of competition among brands more specifically the results confirm the expectation that if there is habit persistence that is if consumer tastes are reinforced by attributes of brands consumed in the past models that do not capture this choice dynamics will overestimate the distance between similar brands furthermore the policy experiments conducted suggest that 1 static models overestimate the short run impact of a price cut on the sales of the brand on promotion 2 price cuts hurt the sales of the more similar brands more and 3 free samples affect relatively less similar brands the most finally this paper studies variety seeking and habit persistence across brands over purchase occasions however variety seeking behavior may also involve the purchase of a portfolio of brands or items at a purchase occasion consumers may buy multiple items knowing that prior to the next trip they may want to consume different items simanson 1990 walsh 1995 this type of behavior can be modeled within the context of dynamic expected utility maximization with forward looking consumers the development and estimation of market structure models that include forward looking consumers who maximize expected utility over a planning horizon incorporating their future tastes and needs and shopping for an inventory of brands remain an important future research issue

the impact of government deficits on money growth in developing countries abstract this paper investigates the relationship between government budget deficits and money growth in the developing countries for which reliabile data exist it is sometimes suggested that it is more likely that money growth follows debt growth in developing countries due to the embryonic state of capital markets and because the central bank generally comes under direct control of the minister of finance our results provide only mixed support for this contention however in the majority of countries in our sample there is no evidence that government deficits affect money growth for high inflation years there seems to be more support for a relationship between deficits and money growth

does the time consistency problem explain the behavior of inflation in the united states abstract this paper derives the restrictions imposed by barro and gordon s theory of time consistent monetary policy on a bivariate time series model for inflation and unemployment and tests those restrictions using quarterly us data from 1960 through 1997 the results show that the data are consistent with the implications of the theory for the long run behavior of the two variables indicating that the theory can explain the initial rise and subsequent fall of inflation over the past four decades the results also suggest that the theory must be extended to account more fully for the short run dynamics that appear in the data

bounded rationality in pricing under state dependent demand do firms look ahead and if so how far the authors propose an empirical procedure to investigate the pricing behavior of manufacturers and retailers in the presence of state dependent demand rather than assuming that firms are perfectl

are fiscal deficits inflationary abstract this paper applies the dynamic panel quantile regression dpqr model under the autoregressive distributional lag ardl specification and examines the deficit inflation relationship in 91 countries from 1960 to 2006 the dpqr model estimates the impact of deficits on inflation at various inflation levels and allows for a dynamic adjustment with the ardl specification the empirical results show that the fiscal deficit has a strong impact on inflation in high inflation episodes and has a weak impact in low inflation episodes the results imply that fiscal consolidation would be more effective in price stabilization the higher the inflation rate is and are consistent with the theoretical model of catao and terrones 2005

behavioral price discrimination in the presence of switching costs we study the strategic impacts of behavioral price discrimination bpd on manufacturers and retailers in a distribution channel when there are switching costs in consumer demand unlike previous empirical studies of behavioral price discrimination which rely only on differences in price elasticity across customers our pricing model allows the firm strategies to additionally account for differences in price elasticity across time due to switching costs we estimate a dynamic pricing model using empirical data from the cola category and through a series of counterfactuals we find that the retailer should simply outsource the data analytics and customization of coupons to manufacturers and improve its profit beyond what it can achieve by proactively couponing on its own we further find that serving as an information broker to sell its customer database to manufacturers can be a vital source of profit to the retailer by contrast manufacturers end up worse off illustrating that customer information

a framework for investigating habits the hand of the past and heterogeneity in dynamic brand choice in this paper we develop a general class of dynamic brand choice models called lightning bolt lb models which are consistent with the theory of random utility maximization of consumer choice behavior the underlying random utility process is markov and the inter temporal evolution of the utility maximizing brand choice process is also markov the models permit parsimonious parameterizations of the random utility process in brand choices with the resulting switching probabilities being functionally related to explanatory variables the model allows for structural state dependence feedback habit persistence inertia and unobserved heterogeneity the theoretical development shows that several well known stochastic brand choice models can be deduced from random utility maximization theory from a managerial perspective the usefulness of the proposed model stems from its ability to separate out the effects of habits state dependence and heterogeneity strong state dependence effects imply incentives for inducing trial of a brand e g product sampling in contrast with state dependence a strong habit persistence effect may be indicative of buyer behavior where inducement of trial of a different brand may not be sufficient to maintain a sustained defection of the consumer from the habitually purchased brand to the trial brand failure to distinguish between these two effects has important implications for example a model that only accounts for state dependence effects would in the presence of only habit persistence incorrectly attribute it to state dependence based on this the manager could decide to embark on an expensive sampling program that might prove ineffective due to the absence of state dependence it is also important to distinguish between the effects of unobserved heterogeneity and state dependence in the absence of true state dependence failing to account for unobservable variations across households such as differences in price sensitivities results in the temporally persistent unobservable elements showing up as state dependence in the model hence a manager may incorrectly opt for sampling as the appropriate marketing action whereas a couponing or price promotion strategy should have been preferred we estimate the model parameters using the ac nielsen household scanner panel data set on catsup purchases further we investigate empirical techniques for overcoming the initial conditions problem that affects many dynamic models of brand choice through simulation analysis using the estimated parameters we show that the calculated profitability of a promotion must take into account the multi period impact due to state dependence further we demonstrate how ignoring heterogeneity can result in spurious state dependence thereby making marketing tactics such as product sampling appear far more attractive than they actually are specifically the model that accounts only for habit persistence and state dependence effects predicts a share increase of 2 4 points through sampling for one of the brands in the empirical analysis once the effects of unobserved heterogeneity are accounted for however this number drops precipitously to 0 3 while even this low number might fulfill the objectives of the brand manager it ensures that expectations are not eight times that number it is important to note that this paper is a first attempt at analyzing the three fundamental dimensions of dynamic brand choice behavior our formulation represents a reduced form approach as opposed to a structural approach other limitations of the model include our focus on time invariant choice sets extensions of the model to situations where choice sets vary over time are possible but are difficult another limitation is the dependence on multivariate extreme value distributions an alternative would be to use multivariate normal distributions i e a probit like structure which has certain useful properties a comparison of the two approaches would be useful empirical extensions of the model to allow for higher order processes and nested logit type model structures could also be fruitful explicitly incorporating variety seeking behavior in the model would further enrich the theoretical framework proposed in this paper

modeling heterogeneity and state dependence in consumer choice behavior in frequently purchased consumer goods markets consumer brand choices exhibit substantial persistence across purchase occasions in this article i estimate a choice model that admits of both heterogeneity in preferences and true state dependence as sources of this persistence using nielsen scanner data on ketchup i find evidence for true state dependence in the choice process even after controlling for a rich heterogeneity structure simulation of the model indicates that the long term effect of a promotion induced purchase on future purchase probabilities is positive but small

the influence of firm s size and international experience on the ownership structure of italian fdi in manufacturing the literature on foreign direct investment fdi has analysed the entry mode choice by multinational enterprises mnes from several theoretical viewpoints nevertheless previous studies have mainly focused on the behaviour of large and established mnes while little attention has been given to small and medium sized firms the paper aims at providing further empirical evidence on the role of firm size and international experience in influencing the ownership structure of fdi the main hypothesis is that smaller firms characterised by financial and managerial con straints as well as firms lacking experience in managing foreign operations suffer from a condition of adverse asym metry in information costs compared to their competitors therefore they are forced to act prudently minimising risk and thus preferring a less control arrangement of foreign sub sidiaries a binomial logistic model is developed with reference to manufacturing foreign direct investments undertaken by italian firms in the period 1986 1993

do customers learn from experience evidence from retail banking we study customers adoption and subsequent switching decisions with regard to a menu of three part tariff plans offered by a commercial bank using a rich panel data set covering 70 510 fee based checking accounts over 30 months before and after the introduction of the plans we find that most customers adopt non cost minimizing plans preferring plans with large monthly allowances and high fixed payments furthermore after adoption customers who exceed their allowances and consequently pay overage fees are more likely to switch to plans with larger allowances than customers who do not experience such fees notably after switching these overage paying customers pay higher monthly payments than before in contrast switching customers who did not pay overage payments before switching pay less after switching our findings unlike those of previous research on experience based learning suggest that the behavior of experienced customers does not converge to the predictions of neoclassical models we p

winners and losers in a major price war abstract although retail price wars have received much business press and some research attention it is unclear how they affect consumer purchase behavior this article studies an unprecedented price war in dutch grocery retailing that started in fall 2003 initiated by the market leader to halt its sliding market share the authors investigate the short and long term effects of the price war on store visits on spending and on the sensitivity of these decisions to weekly prices and price image they use a unique data set with consumer hand scan and perceptual data for a national panel of 1821 households covering two years before and two years after the price war started although the price war initially entailed more shopping around and increased spending spending per visit ultimately dropped because consumers redistributed their purchases across stores the price war made consumers more sensitive to weekly prices and price image which helped both the chain that showed an improvement in price image

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

does central bank independence really matter new evidence for developing countries using a new indicator abstract this paper provides a new indicator for central bank independence cbi based on the turnover rate of central bank governors for 82 developing countries over the period 1980 1989 using this new indicator it is concluded that this proxy for cbi is related to inflation only if the high inflation countries are included in the sample the view that both cbi and inflation are caused by effective opposition towards inflation is not supported using both the extreme bound analysis and sala i martin s method we do not find evidence that cbi is robustly related to economic growth

modern hyper and high inflations since 1947 hyperinflations by cagan s definition in market economies have been rare much more common have been longer inflationary processes with inflation rates above 100 percent per annum based on a sample of 133 countries and using the 100 percent threshold as the basis for a definition of very high inflation episodes this paper examines the main characteristics of such inflations among other things we find that i close to 20 percent of countries have experienced inflation above 100 percent per annum ii higher inflation tends to be more unstable iii in high inflation countries the relationship between the fiscal balance and seigniorage is strong both in the short and long run iv inflation inertia decreases as average inflation rises v high inflation is associated with poor macroeconomic performance and vi stabilizations from high inflation that rely on the exchange rate as the nominal anchor are expansionary

the relationship between inflation and the budget deficit in turkey this article analyzes the empirical relationship between inflation and the budget deficit for the turkish economy by a multivariate cointegration analysis a single equation model shows that the scaled budget deficit as well as income growth and debt monetization significantly affects inflation in turkey the conditional model of inflation is constant and it encompasses a previously estimated model

welfare consequences of gradual disinflation in emerging economies emerging economies display considerable inequality in monetary asset holdings rendering the recent disinflation nontrivial using a small open economy model with uninsurable idiosyncratic risk this paper shows that a gradual decline of 12 in the quarterly inflation rate leads to an aggregate welfare gain of 0 40 in consumption equivalent terms the poor gain less than the economy on aggregate despite holding a more inflation prone financial portfolio this is because unequal cash holdings make inflation tax payments of the poor much smaller than those of the rich when inflation tax revenues finance redistributive transfers that provide insurance cross sectional gains become even more dispersed

research note a cross category model of households incidence and quantity decisions this paper advances the literature on multicategory demand models by simultaneously handling more than one purchase decision of the household we propose a two stage bivariate logit model of incidence and quantity outcomes in multiple categories our results show that cross category promotional spillovers are asymmetric between the two product categories of bacon and eggs the total retail profit responds more to bacon price than to egg price promoting bacon is found to have a bigger impact on egg profit than the impact of egg promotion on bacon profit we decompose 1 the total retail profits as well as 2 the cross category profit impact of a price promotion into its two components and find that 1 23 67 of the total retail profit impact of a promotion on bacon eggs arises on account of quantity effects and 2 40 33 of the increase in egg bacon profit from promoting bacon eggs is on account of quantity effects

inflation in open economies abstract this paper relates the time consistent inflation rate to the degree of trade openness of an economy the mechanism linking the welfare effects of monetary surprises and hence the incentives to inflate to openness does not rely on a large country terms of trade effect but rather is due to imperfect competition and nominal price rigidity in the non traded sector the empirical evidence supports the main predictions of the model 1997 elsevier science b v

fixed versus flexible exchange rates which provides more fiscal discipline abstract conventional wisdom holds that fixed rates provide more fiscal discipline than do flexible rates in this paper we show that this wisdom need not hold in a standard model in which fiscal policy is endogenously determined by a maximizing fiscal authority the claim that fixed rates induce more discipline stresses that sustained adoption of lax fiscal policies must eventually lead to an exhaustion of reserves and thus to a politically costly collapse of the peg hence under fixed rates bad behavior today leads to punishment tomorrow under flexible rates bad behavior has costs as well the difference is in the intertemporal distribution of these costs flexible rates allow the effects of unsound fiscal policies to manifest themselves immediately through movements in the exchange rate hence bad behavior today leads to punishment today if fiscal authorities are impatient flexible rates by forcing the costs to be paid up front provide more fiscal discipline and higher welfare for the representative private agent the recent experience of sub saharan countries supplies evidence that matches the predictions of the model

price competition in markets with consumer variety seeking we investigate price competition between firms in markets characterized by consumer variety seeking while previous research has addressed the effect of consumer inertia on prices there exists no research on the effects of variety seeking on price competition our study fills this gap in the literature using a two period duopoly framework as in klemperer s analysis of inertial markets we show that the noncooperative pricing equilibrium in a market with consumer variety seeking may be the same as the collusive outcome in an otherwise identical market without variety seeking specifically our variety seeking model implies tacit collusion between firms in both periods unlike the inertia model of klemperer that implies tacit collusion between firms only in the second period but implies fierce price competition in the first period when consumers are assumed to have rational expectations about future prices the implied first period prices increase further which is consistent with what klemperer finds in an inertial market to summarize while our variety seeking analyses support two key results pertaining to second period prices and rational expectations previously derived for inertial markets by klemperer they depart from one key result pertaining to first period prices

a dynamic model of rational addiction evaluating cigarette taxes addiction creates an intertemporal link between a consumer s past and present decisions altering their responsiveness to price changes relative to nonaddictive products we construct a dynamic model of rational addiction and endogenous consumption to investigate how consumers respond to policy interventions that aim to reduce purchases of cigarettes we find that on average the category elasticity is about 35 higher when the model correctly accounts for addiction however some policies spur substitution from more expensive single packs to less expensive cartons of cigarettes resulting in higher overall consumption for some consumers

speculative hyperinflations and currency substitution abstract we propose a rational expectations framework for understanding speculative hyperinflations that end in response to orthodox stabilization programs motivated by a strong degree of hysteresis in the stock of real balances after the end of hyperinflations we provide a cash and credit model in which the money demand exhibits persistence because individuals can establish long lasting credit relationships we use the model to show that if hysteresis in real balances is possible then a fiscal monetary reform that successfully stops a speculative hyperinflation may fail to prevent it we argue that speculative hyperinflationary equilibria are consistent with some key stylized facts observed in extreme hyperinflations

external asymmetries in the euro area and the role of foreign direct investment soon after the introduction of the common currency a divide emerged between two groups in the euro area one comprised of the north european countries achieving external surpluses and the other of the south european countries with large external deficits this paper shows that different patterns of foreign direct investment fdi inflows across the euro area countries contributed to this divergence our theoretical framework shows that if the economy is relatively capital intensive in the production of traded non traded output fdi will be channeled in greater proportions to the traded non traded sector thus improving deteriorating the trade balance focusing on ten euro area countries over the period 1980 2009 we establish a positive negative long run effect of fdi inflows on the trade balance in the north south in the north the positive effect stems from the traded sector fdi inflows that were significantly higher in comparison to the south both before and after the emu in contrast in the south the increased fdi inflows in the post emu era were dominated by investments in the non traded sector when industry level data are employed a positive negative long run effect of manufacturing non manufacturing fdi inflows on the trade balance in the north south is further established

the modern history of exchange rate arrangements a reinterpretation we develop a novel system of reclassifying historical exchange rate regimes one key difference between our study and previous classifications is that we employ monthly data on market determined parallel exchange rates going back to 1946 for 153 countries our approach differs from the imf official classification which we show to be only a little better than random it also differs radically from all previous attempts at historical reclassification our classification points to a rethinking of economic performance under alternative exchange rate regimes indeed the breakup of bretton woods had less impact on exchange rate regimes than is popularly believed

relationships between corruption political orientation and income inequality evidence from latin america abstractthis research sheds light on the analysis of the impact of corruption and political orientation on income distribution in latin america although it has been theoretically demonstrated that corruption worsens the income distribution the empirical evidence has yielded ambiguous results based on biased estimates not considering a measurement error in the estimation of inequality this article fills this gap by correcting the previous measurement error bias in the fixed effects estimation additionally political orientation and its relationship with income inequality are also investigated the sample covers 18 latin american countries between 1996 and 2012 results reveal that corruption increases income inequality

oil shocks and aggregate macroeconomic behavior the role of monetary policy a recent paper by bernanke gertler and watson 1997 suggests that monetary policy could be used to eliminate any recessionary consequences of an oil price shock this paper challenges this conclusion on two grounds first we question whether the federal reserve actually has the power to implement such a policy for example we consider it unlikely that additional money creation would have succeeded in reducing the fed funds rate by 900 basis points relative to the values seen in 1974 second we point out that the size of the effect that bernanke gertler and watson attribute to oil shocks is substantially smaller than that reported by other researchers primarily due to their choice of a shorter lag length than that used by other researchers we offer evidence in favor of the longer lag length employed by previous research and show that under this specification even the aggressive federal reserve policies proposed would not have succeeded in averting a downturn
