structural estimation and the border puzzle abstract we revisit anderson and van wincoop s anderson james and eric van wincoop 2003 gravity with gravitas a solution to the border puzzle american economic review 93 170 192 claim that structural estimation solves the u s canadian border puzzle we find this claim tenuous as the proposed solution attributes to structural estimation the effects of added u s data and an assumption that u s and canadian border costs are symmetric estimated canadian and u s multilateral resistance measures which are the foundation of anderson and van wincoop s argument depend critically on the symmetric costs assumption even accepting symmetry we show that structurally consistent estimates of the canadian border effect are only marginally smaller than the ols estimates when we exclude the arguably non comparable u s data

investigating m3 money demand in the euro area abstract euro area monetary growth has exceeded its target since 2001 likewise recent empirical studies did not find evidence in favour of a stable long run money demand function in contrast to the bulk of the literature we are able to identify a stable long run money demand relationship this result is obtained when the analysis is done without the short run homogeneity restriction between money and prices the basic equation can be improved by allowing for asymmetric adjustment in a low inflation environment opportunity costs of holding money have decreased thus the apparent monetary overhang is reconciled within standard models

nonlinear monetary dynamics this article uses the correlation dimension technique along with the residual and shuffle tests to look for evidence of nonlinear dynamic structure in various weekly monetary aggregates their components the monetary base and the money multipliers the results support the barnett and chen 1988 and chen 1988 findings of nonlinearity in divisia m2 divisia m3 and simple sum m2 evidence of nonlinear structure is also found for simple sum m1 currency demand deposits all checkable deposits m3 minus m2 the monetary base and the multipliers of m1 m2 and m3

money income prices and interest rates including data from the 1980s sharply weakens the postwar time series evidence indicating significant relationships between money however defined and nominal income or between money and either real income or prices separately focusing on data from 1970 onward destroys this evidence altogether evidence indicating cointegration of real income and real money balances with due allowance for the effect of interest rates also deteriorates when the sample extends through the 1980s a positive finding is that the spread between the commercial paper rate and the treasury bill rate consistently contains highly significant information about future movements in real income copyright 1992 by american economic association

the distributional effects of capital account liberalization abstract episodes of account liberalization increase the gini measure of inequality based on panel data estimates for 149 countries from 1970 to 2010 these episodes are also associated with a persistent increase in the share of income going to the top we investigate three channels through which these impacts could occur first the impact of liberalization on inequality is stronger where credit markets lack depth and financial inclusion is low positive impacts of liberalization on poverty rates also vanish when financial inclusion is low second the impact on inequality is also stronger when liberalization is followed by a financial crisis third liberalization seems to alter the relative bargaining power of firms and workers the labor share of income falls in the aftermath of capital account liberalization

modeling the demand for narrow money in the united kingdom and the united states abstract despite the importance of well specified empirical money demand functions for inference forecasting and policy problems in modeling have arisen concerning the economic theories of money demand the data institutional frameworks financial innovation and econometric implementation by developing constant data coherent m 1 demand equations for the u k and the u s we investigate these issues and explain such puzzles as missing money the great velocity decline and the recent explosion in m 1 the endogeneity of money the lucas critique and the non invertibility of our m 1 models are also discussed

disagreement portfolio optimization and excess volatility disagreement a key factor inducing trading has been receiving ever increasing attention in recent years most research has focused on disagreement about the expected returns several authors have shown that if the average belief coincides with the true expected return in the portfolio context prices are unaffected by disagreement in this paper we study the pricing effects of disagreement about return variances we show that i disagreement about variances has systematic and significant pricing effects more disagreement leads to higher prices and ii prices are very sensitive to the degree of disagreement even if the average belief about the variance is constant tiny fluctuations in the disagreement about the variance lead to substantial price fluctuations this second result may offer an explanation for the excess volatility puzzle when small changes in the degree of disagreement occur they induce relatively large price changes yet the changes in disagreement may be hard to directly detect empirically leading to apparent excess volatility

choosing the open sea the cost to the uk of staying out of the euro abstract in this paper we provide an estimate of the trade flows that there would have been between the uk and its main trading partners if the uk had joined the euro as an alternative approach to the standard log linear gravity equation we employ the synthetic control method we show that the aggregate trade flows between britain and eurozone members would have been 16 higher if the uk had adopted the euro we also provide an estimate of the hypothetical euro s effect on trade flows between the uk and non euro countries our results suggest that the adoption of the european currency would also have led to a substantial increase in british trade flows with non euro members finally we provide a new estimate of the euro s trade impact for euro members our results suggest that the adoption of the single currency led to an increase in intra european trade flows of between 19 and 55

the demand for m1 in the u s a 1960 1988 estimated u s m1 demand functions appear unstable regularly breaking down over 1960 1988 e g missing money great velocity decline m1 explosion we propose a money demand function whose arguments include inflation real income long term bond yield and risk t bill interest rates and learning curve weighted yields on newly introduced instruments in m1 and non transactions m2 the model is estimated in dynamic error correction form it is constant and with an equation standard error of 0 4 variance dominates most previous models estimating alternative specifications explains earlier breakdowns showing the model s distinctive features to be important in accounting for the data

long run money demand revisited evidence from a non linear approach abstract in this paper we argue that employing the conventional linear cointegration approach in examining long run money demand may not be appropriate after taking into account the existence of transaction costs we provide evidence to show that deviations from equilibrium money demand follow an exponential smooth transition autoregressive process that is mean reverting outside a given range and has a unit root inside the range our findings also provide an alternative explanation for the failure of much of the existing literature to support a long run money demand function

long run income and interest elasticities of money demand in the united states econometric techniques designed to accommodate nonstationary data are used to reexamine the stability of interest and income elasticities of money demand in the united states estimates based on postwar monthly data reveal a stable relationship between m1 velocity and various measures of interest rates that proxy the opportunity cost of holding money balances tests for the existence of cointegration and methods used to estimate the income and interest elasticities are based on procedures prescribed by soren johansen 1988 corresponding error correction estimates offer insight as to the dynamics of the process that maintains the equilibrium relation between velocity and interest rates copyright 1991 by mit press

the reincarnation of keynesian economics this paper discusses the reemergence of keynesian economics during the past decade it highlights the substantial differences between new keynesian economics and the convictions of early keynesians in particular it points out that new keynesians have adopted many views that were once considered monetarist or classical it concludes that the term keynesian may have outlived its usefulness this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

asset returns with transactions costs and uninsured individual risk abstract we explore whether incorporating an explicit motive for holding liquid assets within an equilibrium asset pricing model helps explain the following features of asset returns and turnover in the post war u s economy i the low risk free real interest rate ii the large spread between returns on liquid assets and stocks and iii the greater transaction velocity of liquid assets relative to stocks we introduce a demand for liquid assets by adding uninsured individual risk together with differential costs of trading securities numerical simulations attempting to match the return data generate a ratio of liquid assets to income considerably below observed levels

characterizing nonlinearities in business cycles using smooth transition autoregressive models during the past few years investigators have found evidence indicating that various time series representing business cycles such as production and unemployment may be nonlinear in this paper it is assumed that if the time series is nonlinear then it can be adequately described by a smooth transition autoregressive star model the paper describes the application of these models to quarterly logarithmic production indices for 13 countries and europe tests reject linearity for most of these series and estimated star models indicate that the nonlinearity is needed mainly to describe the responses of production to large negative shocks such as oil price shocks

long run money demand in taiwan revisited evidence from a cointegrating str approach previous studies on the nonlinearity of the money demand function focus only on short run dynamics and assume that the long run cointegrated relationship is linear which according to economic theory need not be the case thus this article focuses on the variables that make up the long run money demand function in taiwan and their determinants by using the cointegrating smoothing transition regression cstr test developed by choi and saikkonen 2004 this model is more general than the previous str model in that it may contain several transition functions and has more than a single transition variable we demonstrate our empirical results for robustness and adopt two models to ascertain whether or not the stock price should be added as a determinant of the demand for money our empirical results show the existence of a stationary long run relationship among real money demand functions for the period from 1976q1 to 2005q1 and the robustness test covers the 1980q1 2005q1 period in taiwan by comparing

detection of switching cointegration rank allowing for switching lag structure an application to money demand function a new method is developed for detecting regime switches between cointegration and no cointegration at unknown times allowing for switching lag structure in this method time series observations are divided into several segments and a regression model with or without cointegration is fitted to each segment the goodness of fit of the global model composed of these local models is evaluated using the corresponding modified information criterion and the division which minimizes this criterion defines the best model simulation results suggest that the proposed method works well empirical results indicate that money demand is well described by the proposed method in canada uk and japan

long run money demand in canada in search of stability the authors search for a long run cointegrating relationship among real money balances real income and interest rates extending the work of steve ambler and algin paquet 1990 who explore this issue in the canadian context employing the methods of robert f engle and clive w granger 1987 first they uncover parameter estimates of the cointegrated relationships using three different methods of estimation second the authors employ the hansen 1992 procedure to search for structural instability in cointegrating relationships with unknown break points they find empirical support for a stable cointegrating relationship among real m1 real income and short term interest rates in canada for the period 1953 1 1990 4 copyright 1996 by mit press

differential information and security market equilibrium we propose a simple model of equilibrium asset pricing in which there are differences in the amounts of information available for developing inferences about the returns parame ters of alternative securities in contrast with earlier work we show that parameter uncer tainty or estimation risk can have an effect upon market equilibrium under reasonable conditions securities for which there is relatively little information are shown to have relatively higher systematic risk when that risk is properly measured ceteris paribus the initially very limited model is shown to be robust with respect to relaxation of a number of its principal assumptions we provide theoretical support for the empirical examination of at least three proxies for relative information period of listing number of security returns observations available and divergence of analyst opinion

international portfolio diversification with estimation risk international portfolio diversification has long been advocated as a way of enhancing average returns while reducing portfolio risk for the investor who considers diversifying into foreign securities this proposition however relies on the assumption that the required inputs to the classical mean variance analysis are known with certainty typically expected returns variances and covariances are simply replaced by their ex post sample values and the optimal portfolio is derived without mentioning the uncertainty inherent in these parameter values but the rational investor should take this uncertainty into account when forming expectations and probably will consider estimators that are less subject to estimation error than the classical sample mean this paper investigates alternative estimators of expected returns and their implications for the alleged gains from diversification an important observation is the crucial influence that errors in estimating expected returns have on portfolio analysis a closer examiprevious studies of international portfolio diversification have relied on ex post meanvariance analysis without considering the problem of estimation risk typically past averages are substituted for expected returns and no allowance is made for the uncertainty inherent in these parameter values first i demonstrate the shortcomings of such an approach and second i investigate another method of estimating expected returns initially proposed by stein by shrinking the sample averages toward a common mean i find that the out of sample performance of the optimal portfolio is substantially increased one of the implications of this method is that the classical conclusions vastly overestimate the possible gains in average returns instead benefits from diversification are more likely to accrue from a reduction in risk this paper draws on part of my dissertation at the university of chicago i am grateful to arnold zellner michael mussa george constantinides and especially john bilson for useful discussions and comments numerous improvements were also suggested by the referee this research received the generous financial support of the college interuniversitaire d etudes doctorales dans les sciences du management

breaks in money demand during the last twenty years beginning with the provocative paper by goldfeld 5 that revealed the case of the missing money the question of whether money demand the relationship between money income and an interest rate is stable has been intensively investigated using a variety of econometric techniques currently the most popular framework for examining the behavior of money demand is the cointegration framework in this framework the stationarity of money demand instead of the stability of money demand is evaluated earlier tests of the stability of money demand typically centered on whether the coefficient estimates were stable i e not subject to a structural break these tests did not consider the underlying time series aspects of the variables in money demand or the time series properties of their joint relationship prior to estimation as is now common given the seminal work of engle and granger 1 since then newer tests have focussed on the time series properties of the money demand variables and whether the joint relationship between the variables is stationary i e whether the variables are cointegrated engle and granger 1 and johansen and juselius 10 offer cointegration estimation procedures that have been applied by numerous researchers to the money incomeinterest rate relationship the pervasive finding is that money demand is non stationary see section ii below structural stability has not typically been a facet of investigation however the issues of stationarity and stability should not necessarily be treated independently failure to take account of structural change may bias the results in favor of non stationarity as shown in perron 16 1 history suggests that the economic environment and monetary institutions regulations and operating procedures have changed over time in the early 1970s the fixed exchange rate system collapsed when the gold exchange standard was abandoned and the u s dollar became a fiat currency during that same time the u s suffered an oil price shock that produced accelerating inflation and stagnant gdp growth an outcome that had never before been experienced in

smooth adjustment econometrics and inventory theoretic money management abstract a growing number of empirical papers use miller orr s s money management as economic motivation for application of non linear smooth adjustment models this paper shows such models are not implied by the miller orr economy instead the miller orr economy implies non standard smooth adjustment as derived in the neglected and misinterpreted work of milbourne et al 1983 remarkably this function includes a varying weight on the lagged dependent variable capturing static not dynamic effects interpretations of these apparent dynamics are presented some of which may be useful in non monetary s s contexts results imply a new agenda for applied smooth adjustment modeling of money

the conduct of monetary policy nowadays the central bank of a country is the monopoly supplier of legal tender currency the commercial banks are committed to making their deposits convertible at par into such currency so the banks need to keep reserves in the form of currency and deposits at the central bank the central bank primarily conducts its policy by buying and selling financial securities e g treasury bills or foreign exchange in exchange for its own liabilities i e open market operations academic economists generally regard such operations as adjusting the quantitative volume of the banks reserve base and hence of the money stock with rates prices in such markets simultaneously determined by the interplay of demand and supply central bank practitioners almost always view themselves as unable to deny the banks the reserve base that the banking system requires and see themselves as setting the level of interest rates at which such reserve requirements are met with the quantity of money then simultaneously determined by the portfolio preferences of private sector banks and non banks this difference in perceptions is discussed again in section iii whether the monetary policy operations of central banks should be viewed primarily in terms of quantity or rate setting actions though of course one is the dual of the other these had allowed inflation and inflationary expectations to become entrenched by the end of the i970s a selection of representative statistics for a number of the leading industrialised countries is given in table i below this table indicates a common pattern among the countries of interaction between interest rates inflation and the growth of output the first period i969 78 is marked by high inflation negative real interest rates and slightly above average growth the second period i979 82 by very high nominal and high real interest rates high but falling inflation and very low output growth the final period i983 7 is marked by much lower inflation lower nominal but still high real interest rates and a recovery in output growth in some cases to above average rates in contrast the relationship in these countries between the growth of their chosen key monetary aggregate and nominal incomes appears much weaker also see clinton and chouraqui i987 especially p 7 whether measured in terms of monetary growth or in terms of real interest rates i e after adjustment for prospective future inflation policy during the

transactions costs and nonlinear adjustment in real exchange rates an empirical investigation eolquilibrium models of real exchange rate determination in the presence of transactions costs imply a nonlinear adjustment process toward purchasing power parity ppp conventional cointegration tests which ignore the effect of transactions costs may be biased against the long run ppp hypothesis our results using both monthly data for the interwar period and annual data spanning two centuries clearly reject the linear framework in favor of an exponential smooth transition autoregressive process the systematic pattern in the estimates of the nonlinear models provides strong evidence of mean reverting behavior for ppp deviations and helps explain the mixed results of previous studies

the demand for money in the united states evidence from cointegration tests this paper uses recent cointegration test procedures to investigate the underlying economic relationship between real money balances real income and interest rates for the united states unlike recent studies of money demand the authors analysis uses quarterly data spanning the period 1915 88 thus providing a sample encompassing a wide variety of economic experiences the evidence presented indicates that the broader m2 measure of money is the preferable measure with which to consider the long run effects of monetary policy copyright 1991 by ohio state university press

intra national home bias some explanations wolf demonstrates that trade within the united states appears substantially impeded by state borders we revisit this finding with improved data we show that much intranational home bias can be explained by wholesaling activity shipments by wholesalers are much more localized within states than shipments from manufacturing establishments controlling for relative prices and the use of actual rather than imputed shipment distances also reduces home bias estimates

money demand function estimation by nonlinear cointegration conventionally the money demand function is estimated using a regression of the logarithm of money demand on either the interest rate or the logarithm of the interest rate this equation is presumed to be a cointegrating regression in this paper we aim to combine the logarithmic specification which models the liquidity trap better than a linear model with the assumption that the interest rate itself is an integrated process the proposed technique is robust to serial correlation in the errors for the usa our new technique results in larger coefficient estimates than previous research suggested and produces superior out of sample prediction copyright 2007 john wiley sons ltd

trade in polarized america the border effect between red states and blue states political and cultural polarization in the united states is widely discussed but does it relate to any economic disconnection among states we estimate the border effect between red and blue states using the gravity equation with a nonlinear generalized method of moments estimator to simultaneously overcome the problems associated with endogeneity cross state price differences and zero trade flow the border effect is robustly confirmed for the 2000s while not so robustly detected for the 1990s notably in 2007 the border reduces trade between red and blue states to approximately 75 of the trade within each set of states this estimated border effect is much smaller than the united states canada national border effect estimated by anderson and van wincoop 2003 and by feenstra 2002 yet is comparable to the border effect that nitsch and wolf 2009 find for the former west and east germanies approximately loyears after reunification while the border effect in germany after reunification is decreasing the border effect between the red and blue states is emerging we also find the border effect is more significant for consumption rather than intermediate goods the border effect is an important indicator for a potential dismantling of the economic connectivity in the united states jel d72 f10 fi5 r1 i introduction recent u s presidential elections have raised concern about polarization in u s politics and culture namely the united states is divided into two nations the red states we call it the red nation preserving the term state for an individual state and the blue states the blue nation in the red nation culturally and religiously conservative republicans are dominant while in the blue nation liberal democrats are the majority so far the focus of the discussion is the extent of the polarization abramowitz and saunders 2008 fiorina et al 2008 its determinants gelman et al 2010 and its implications on federal policy making glaeser et al 2005 mellow and trubowitz 2005 economic implications have not been largely discussed however the polarization may suggest economic divisions because it is a sign of geographic sorting of people and their preferences this article provides evidence that economic disconnectivity between the red and blue nations emerged in the 2000s we explore 1 whether there is a border effect on interstate trade 2 if the effect exists how large it is and 3 what types of goods are most affected in the context of existing literature and recent u s political and cultural events we then provide possible explanations for our findings this study uses a gravity equation of international trade to examine the effect of the fictional national border between the red and blue nations the methodology was originally applied by mccallum 1995 to estimate the degree of impact of the national border on trade between the united states and canada he finds that intercountry trade is less than 5 of the intracountry trade of canada controlling for other factors following mccallum s 1995 work several studies have proposed methodological improvements we apply an updated estimation method nonlinear generalized method of moments gmm estimator of a gravity equation to examine the border effect between the red and blue nations our analysis finds a statistically and economically significant border effect between the red and blue nations especially in years 2002 and 2007 we examine the border effect in 1993 1997 2002 and 2007 the years in which trade flow data are available from the federal commodity flow survey cfs the border effect is not robustly found in 1993 and 1997 however it is robustly detected in 2002 and 2007 even with additional controls or alternative specifications at the industry level analysis we find that the border effect is significant for consumption goods such as food tobacco and printed products but not for intermediate products i
