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

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

modelling sovereign credit spreads with international macro factors the case of brazil 1998 2009 abstract this paper develops a macro finance model of the brazilian economy and its sovereign debt markets that allows for domestic and international macroeconomic influences as well as swings in investor confidence it finds significant evidence of common trends in the us and brazilian economies and bond markets as well as spillover effects from us inflation and business cycles to the brazilian economy the us fed funds rate influences brazilian sovereign spreads as do brazilian inflation and policy rates the brazilian confidence factor dominates the behavior of the spreads during periods of crisis and we find that it also has a powerful effect on the level and volatility of macroeconomic variables these results suggest that the macro finance approach could throw light upon the behavior of other economies that are troubled by sovereign risk

the changing nature of stock and bond volatility this article examines the changing nature of u s stock and bond risk from 1871 through 2000 and the implications for asset allocation using geometric means and standard deviations we examine nominal and inflation adjusted monthly returns over nonoverlapping 5 year periods as well as annual returns over periods of approximately 25 years and we document how stock and bond volatility changed over the period our analysis suggests that the relative change in the volatility of stocks and volatility of bonds over the past 50 years has increased the importance of stocks in asset allocation the change is even more pronounced when inflation is considered

stock market volatility and international business cycle dynamics evidence from oecd economies abstract how does a surprise movement in stock market volatility affect our forecasts of future output across countries this paper studies the time series and cross sectional responses of output to variation in stock market volatility across 27 countries over 40 years controlling for a number of country specific characteristics high levels of stock market volatility are detrimental to future output growth not only after financial crises as previously emphasized in the literature but also in non crisis periods output growth and interest rates react negatively to a random shock to volatility and revert to their means quickly thereafter moreover these results are robust after controlling for economic policy uncertainty the level of financial development and the direction of the market

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

exploiting the conditional density in estimating the term structure an application to the cox ingersoll and ross model we propose an empirical method that utilizes the conditional density of the state variables to estimate and test a term structure model with known price formulae using data on both discount and coupon bonds the method is applied to an extension of a two factor model due to cox ingersoll and ross 1985 cir our results show that estimates based on only bills imply unreasonably large price errors for longer maturities we reject the original cir model using a likelihood ratio test and conclude that the extended cir model also fails to provide a good description of the treasury market

inventories and the business cycle an equilibrium analysis of s s policies we develop an equilibrium business cycle model where nonconvex delivery costs lead firms to follow s s inventory policies calibrated to postwar us data the model reproduces two thirds of the cyclical variability of inventory investment moreover it delivers strongly procyclical inventory investment greater volatility in production than sales and a countercyclical inventory to sales ratio our model challenges several prominent claims involving inventories including the widely held belief that they amplify aggregate fluctuations despite the comovement between inventory investment and final sales gdp volatility is essentially unaltered by inventory accumulation because procyclical inventory investment diverts resources from final production thereby dampening fluctuations in sales

an open economy macro finance model of international interdependence the oecd us and the uk abstract this paper develops a multi country macro finance model to study international economic and financial linkages this approach models the economy and financial markets jointly using both types of data to throw light on such issues the world economy is modelled using data for the us and aggregate oecd economies as well as the us treasury bond market using latent variables to represent a common inflation trend and a us real interest rate factor we find strong evidence of global effects on both the us and uk calling into question the standard closed economy macro finance specification these economic linkages also help to explain the co movement of yields in the us and uk treasury bond markets

measuring financial asset return and volatility spillovers with application to global equity markets we provide a simple and intuitive measure of interdependence of asset returns and or volatilities in particular we formulate and examine precise and separate measures of return spillovers and volatility spillovers our framework facilitates study of both non crisis and crisis episodes including trends and bursts in spillovers and both turn out to be empirically important in particular in an analysis of sixteen global equity markets from the early 1990s to the present we find striking evidence of divergent behavior in the dynamics of return spillovers vs volatility spillovers return spillovers display a gently increasing trend but no bursts whereas volatility spillovers display no trend but clear bursts

equilibrium analysis of portfolio insurance a martingale approach is used to characterize general equilibrium in the presence of portfolio insurance insurers sell to noninsurers in bad states and general equilibrium requires that the risk premium rises to induce noninsurers to increase their holdings we show that portfolio insurance increases price volatility causes mean reversion in asset returns raises the sharpe ratio and volatility in bad states and causes volatility to be correlated with volume we also explain why out of the money sp that is the demand for an absolute level of price protection is equivalent to a demand for put options 1 we show that a similar argument can be used in a

stochastic volatility in a macro finance model of the u s term structure of interest rates 1961 2004 this paper generalizes the standard homoscedastic macro finance model by allowing for stochastic volatility using the square root specification of the mainstream finance literature empirically this specification dominates the standard model because it is consistent with the square root volatility found in macroeconomic time series thus it establishes an important connection between the stochastic volatility of the mainstream finance model and macro economic volatility of the okun friedman type this research opens the way to a richer specification of both macro economic and term structure models incorporating the best features of both macro finance and mainstream finance models

dynamic specifications in optimizing trend deviation macro models abstract as noted in surveys by goodfriend and king in b bernanke j rotemberg eds nber macroeconomics annual mit press cambridge ma 1997 pp 231 283 and walsh monetary theory and policy mit press cambridge ma and exemplified by models analyzed in taylor 1999 there is encouraging progress in developing optimizing trend deviation macro models that provide useful insights into the transmission and design of monetary policy several controversial features of a minimalist trend deviation model with optimizing households firms and bond traders are examined dynamic specifications are suggested to improve the data based realism while preserving the simplicity of the minimalist model

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

term structure evidence on interest rate smoothing and monetary policy inertia abstract numerous studies have used quarterly data to estimate monetary policy rules or reaction functions that appear to exhibit a very slow partial adjustment of the policy interest rate the conventional wisdom asserts that this gradual adjustment reflects a policy inertia or interest rate smoothing behavior by central banks however such quarterly monetary policy inertia would imply a large amount of forecastable variation in interest rates at horizons of more than 3 months which is contradicted by evidence from the term structure of interest rates the illusion of monetary policy inertia evident in the estimated policy rules likely reflects the persistent shocks that central banks face

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

spillover effects in energy futures markets price discovery in crude oil and refined oil products has been extensively undertaken in organised futures markets for over a decade now there are two dominant such markets today the first one in the new york mercantile exchange and the second in london s international petroleum exchange with the demise of opec as the leading price setter for crude and products nymex light sweet crude and brent crude have usurped the role of benchmark grades for price setting to date considerable work has been done to scrutinise the degree to which these two markets price efficiently but little with regard to the way the two markets interact participants in these markets move with relative ease from one market to the other and usually take positions in both of them it is of interest therefore to investigate the information transmission mechanism by looking at spillover effects and perhaps identify which market is the true price leader this paper is a first attempt to look at such a problem in the energy market although similar studies have been done on stock market indices it is found that substantial spillover effects do exist when both markets are trading simultaneously although ipe morning prices seem to be considerably affected by the close of the previous day on nymex q 2001 elsevier science b v all rights reserved

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

a structural decomposition of the us yield curve abstract by expanding the macro part of macro finance models historical fluctuations in us bond yields turn out to be largely consistent with the rational expectations hypothesis we estimate a medium scale macro finance dsge model of the term structure to establish this our finding contrasts with existing macro finance models and suggests that their small scale or non structural perspective on the macroeconomy mutes expectations thereby underestimating the expectations hypothesis potential out of sample forecasts are competitive with more flexible term structure models given the empirical validation we interpret various episodes through the lens of the model and investigate which structural shocks cause the yield curve to contain information about future growth

expectations bond yields and monetary policy through explicitly incorporating analysts forecasts as observable factors in a dynamic arbitrage free model of the yield curve this research proposes a framework for studying the impact of shifts in market sentiment on interest rates of all maturities an empirical examination reveals that survey expectations about inflation output growth and the anticipated path of monetary policy actions contain important information for explaining movements in bond yields estimates from a forward looking monetary policy rule suggest that the central bank exhibits a preemptive response to inflationary expectations while accommodating output growth and monetary policy expectations forecasted gdp growth plays a significant role in explaining time variation in the market prices of risk the sensitivity of long yields is linked to the persistence of expected inflation under the risk neutral measure models of this type may provide traders and policymakers with a new set of tools for formally assessing the reaction of bond yields to shifts in market expectations the author 2010 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oxfordjournals org oxford university press

bond yields and the federal reserve bond yields respond to policy decisions by the federal reserve and vice versa to learn about these responses i model a high frequency policy rule based on yield curve information and an arbitrage free bond market in continuous time the fed s target is a pure jump process jump intensities depend on the state of the economy and the meeting calendar of the federal open market committee the model has closed form solutions for yields as functions of a few state variables introducing monetary policy helps to match the whole yield curve because the target is an observable state variable that pins down its short end and introduces important seasonalities around fomc meetings the volatility of yields is snake shaped which the model explains with policy inertia the policy rule crucially depends on the two year yield and describes fed policy better than taylor rules

international spillovers of u s financial volatility abstract we study the international spillover effects of u s bond and stock market volatility using a panel data set of seventeen developed countries we find significant spillover impacts of u s financial market volatility on international output growth volatility of u s bonds with longer maturities is shown to have a more significant impact on international output growth than volatility of u s bonds with shorter maturities regardless of the maturity of the bonds u s financial market volatility is shown to play a larger role statistically in explaining international output growth than a country s own financial market volatility
