bond market exposures to macroeconomic and monetary policy risks i provide empirical evidence of changes in the u s treasury yield curve and related macroeconomic factors and investigate whether the changes are brought about by external shocks monetary policy or by both to explore this i characterize bond market exposures to macroeconomic and monetary policy risks using an equilibrium term structure model with recursive preferences in which inflation dynamics are endogenously determined in my model the key risks that affect bond market prices are changes in the correlation between growth and inflation and changes in the conduct of monetary policy using a novel estimation technique i find that the changes in monetary policy affect the level of bond yields through their effect on expected inflation while the changes in the correlation between growth and inflation affect both the level as well as the volatility of bond yields consequently the changes in the correlation structure are the main contributor to bond risk premia and to bond market volatility the time variations within a regime and risks associated with moving across regimes lead to the failure of the expectations hypothesis and to the excess bond return predictability regression of cochrane and piazzesi 2005 as in the data

linear quadratic approximation external habit and targeting rules abstract we examine the linear quadratic approximation of nonlinear dynamic stochastic optimization problems a discrete time version of magill 1977a a local analysis of n sector capital accumulation under uncertainty journal of economic theory 15 2 211 219 is generalized to models with forward looking variables paying special attention to second order conditions this is the large distortions case in the literature we apply the approach to monetary policy in a dsge model with external habit in consumption we then develop a condition for target implementability a concept related to targeting rules finally we extend the approach to a comparison between cooperative and non cooperative equilibria in a two country model and show that the small distortions approximation is inappropriate for this exercise

impact of pension system structure on international financial capital allocation abstract recent findings indicate that pension system structure affects private savings and through them the aggregate foreign asset position of a country we present a two country overlapping generations model that explores the relationship between the magnitude of pension guarantees and the resulting portfolio choices of workers the existence of a pay as you go pension system lowers the wealth of the young workers who consequently borrow from abroad to supplement their current consumption and lowers the overall riskiness of their lifetime wealth prompting them to invest in risky equity financed by the selling of safe bonds in particular we are able to replicate and explain the venture capitalist positive net equity accompanied by negative net debt portfolio profile of the united states more broadly we find empirical support for our results in a cross country analysis using data from 110 economies greater amounts of pension spending are associated with international indebtedness long equity positions and short debt positions

why has u s inflation become harder to forecast we examine whether the u s rate of price inflation has become harder to forecast and to the extent that it has what changes in the inflation process have made it so the main finding is that the univariate inflation process is well described by an unobserved component trend cycle model with stochastic volatility or equivalently an integrated moving average process with time varying parameters this model explains a variety of recent univariate inflation forecasting puzzles and begins to explain some multivariate inflation forecasting puzzles as well

second order approximation of dynamic models with time varying risk abstract this paper provides first and second order approximation methods for the solution of non linear dynamic stochastic models in which the exogenous state variables follow conditionally linear stochastic processes displaying time varying risk the first order approximation is consistent with a conditionally linear model in which risk is still time varying but has no distinct role separated from the primitive stochastic disturbances in influencing the endogenous variables the second order approximation of the solution instead is sufficient to get this role moreover risk premia evaluated using only a first order approximation of the solution will be also time varying

dynamic effects of monetary policy shocks on macroeconomic volatility we use a simple new keynesian model with firm specific capital non zero steady state inflation long run risks and epstein zin preferences to study the volatility implications of a monetary policy shock an unexpected increase in the policy rate by 150 basis points causes output and inflation volatility to rise around 10 above their steady state standard deviations var based empirical results support the model implications that contractionary shocks increase volatility the volatility effects of the shock are driven by agents concern about the in ability of the monetary authority to reverse deviations from the policy rule and the results are re enforced by the presence of non zero trend inflation

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

federal reserve credibility and the term structure of interest rates abstract in this paper we show how the degree of central bank credibility influences the level slope and curvature of the term structure of interest rates in an estimated structural model we find that historical yield curve data are best matched by the federal reserve conducting policy in a loose commitment framework rather than the commonly used discretion and full commitment assumptions the structural impulse responses indicate that the past history of realized shocks plays a crucial role in determining the dynamic effects of monetary policy on the yield curve finally the regime switching framework allows us to estimate likely re optimization episodes which are found to impact the middle of the yield curve more than the short and long end

long run risks in the term structure of interest rates estimation summary this paper estimates a model in which persistent fluctuations in expected consumption growth expected inflation and their time varying volatility determine asset price variation the model features epstein zin recursive preferences which determine the market price of macro risk factors analysis of the us nominal term structure data from 1953 to 2006 shows that agents dislike high uncertainty and demand compensation for volatility risks also the time variation of the term premium is driven by the compensation for inflation volatility risk which is distinct from consumption volatility risk the central role of inflation volatility risk in explaining the time varying term premium is consistent with other empirical evidence including survey data in contrast the existing long run risks literature emphasizes consumption volatility risk and ignores inflation specific time varying volatility the estimation results of this paper suggest that inflation specific volatility risk is essential for fitting the time series of the us nominal term structure data copyright 2012 john wiley sons ltd

public budgetary rules and gdp growth an empirical study on oecd and twelve european countries we study the long term effects of budgetary rules on gdp growth rate and analyse the determinants of the short term gdp growth dynamics for both a sample of 19 oecd and a subsample of 12 european countries we show that in the long run improvements in the cyclically adjusted budget balance as well as increases in the tax burden have negative effects on gdp growth the highest effect of fiscal policy on gdp growth would be obtained if the structural deficits were used to increase the market size by reducing the tax burden in line with barro 1990 a deficit financed reduction of tax burden has a stronger effect for european than for oecd countries because in europe the government size with respect to market size is too large therefore if gdp growth is a dominant policy objective in europe specific actions should redress the 2012 treaty toward a reduction of the tax burden

the macroeconomic effects of large scale asset purchase programmes the effects of asset purchase programs on macroeconomic variables are likely to be moderate we reach this conclusion after simulating the impact of the federal reserve s second large scale asset purchase program lsap ii in a dsge model enriched with a preferred habitat framework and estimated on u s data our simulations suggest that such a program increases gdp growth by less than half a percentage point although the effect on the level of gdp is very persistent the program s marginal contribution to infl ation is very small one key reason for our fi ndings is that we estimate a small degree of fi nancial market segmentation if we enrich the set of observables with a measure of long term debt the semi elasticity of the risk premium to the amount of debt in privatesector hands is substantially smaller than that reported in the recent empirical literature in this case our baseline estimates of the effects of lsap ii on the macroeconomy decrease by at least a factor of two throughout the analysis a commitment to an extended period at the zero lower bound for nominal interest rates increases the effects of asset purchase programs on gdp growth and infl ation

monk mortgages in a new keynesian model abstract there has been much interest recently in the role of household long term mortgage debt in the transmission of monetary policy this paper offers a tractable framework that integrates the long term debt channel with the standard new keynesian channel providing a tool for monetary policy analysis that reflects the recent debates in the literature as there is a nontrivial role in the model for both short and long term debt it provides a laboratory to investigate the effects of monetary policy operating not only through its current short term actions but also through expected persistent changes in its stance

aggregate and regional house price to earnings ratio dynamics in the uk this paper examines the time series properties of house price to earnings ratio hper in the uk using aggregate and regional data specifically we utilise a series of unit root tests to examine the null hypothesis of nonstationary hpers these include linear tests as well as a nonlinear test and also a test which accounts for abrupt structural change the results are against the notion of stationary hpers this implies that house prices may permanently diverge from earnings

yield curve in an estimated nonlinear macro model this paper estimates a sticky price macro model with us macro and term structure data using bayesian methods the model is solved by a nonlinear method the posterior distribution of the parameters in the model is found to be bi modal the degree of nominal rigidity is high at one mode sticky price mode but is low at the other mode flexible price mode i find that the degree of nominal rigidity is important for identifying macro shocks that affect the yield curve when prices are more flexible a slowly varying inflation target of the central bank is the main driver of the overall level of the yield curve by changing long run inflation expectations in contrast when prices are more sticky a highly persistent markup shock is the main driver the posterior probability of each mode is sensitive to the use of observed proxies for inflation expectations ignoring additional information from survey data on inflation expectations significantly reduces the posterior probability of the flexible price mode incorporating this additional information suggests that yield curve fluctuations can be better understood by focusing on the flexible price mode considering nonlinearities of the model solution also increases the posterior probability of the flexible price mode although to a lesser degree than using survey data information

the term structure of interest rates in a dsge model with recursive preferences abstract a dynamic stochastic general equilibrium dsge model in which households have epstein and zin recursive preferences is solved with perturbation the parameters governing preferences and technology are estimated by maximum likelihood using macroeconomic data and the term structure of interest rates the estimates imply a large risk aversion an elasticity of intertemporal substitution higher than one and substantial adjustment costs furthermore the paper identifies the tensions within the model by estimating it on subsets of these data the analysis concludes by pointing out potential extensions that may improve the model s fit

fiscal stabilizations when do they work and why abstract this paper studies the determinants and channels through which fiscal contractions influence the dynamics of the debt to gdp ratio and gdp growth using data from a panel of oecd countries the paper shows that the success of fiscal adjustments in decreasing the debt to gdp ratio depends on the size of the fiscal contraction and less on its composition the rate of growth of output matters too but higher gdp growth does not drive the success of a fiscal stabilization in contrast whether a fiscal adjustment is expansionary depends largely on the composition of the fiscal maneuvre in particular stabilizations implemented by cutting public spending lead to higher gdp growth rates the effects of the composition on growth work mostly through the labor market rather than through agents expectations of future fiscal policy finally the evidence suggests that successful and expansionary fiscal contractions are not the result of accompanying expansionary monetary policy or exchange rate devaluations

fiscal discipline and the budget process the critical economic policy issue for many oecd countries developing countries and transition economies currently is fiscal consolidation and the maintenance of long run fiscal balance two related components underlie this general goal first several countries face the issue of deficit reduction particularly those countries with high debt gdp ratios second it is becoming increasingly apparent that major reforms of the welfare system and specifically of social security systems are critical ingredients of a long lasting fiscal consolidation see alesina and perotti 1995a in the case of monetary policy a constructive discussion has generated a widespread consensus about the benefits of different monetary institutions relatively few economists dispute the benefits of a certain amount of central bank independence even though different commentators and policymakers may disagree on the optimal degree of independence also a contracting approach has highlighted the benefit of inflation targeting and of certain institutional relationships contracts between the executive and the central bank a similar theoretical and empirical discussion on the role of budget procedures and budget institutions is just beginning in this paper we ask the following two questions i do budget procedures matter for the determination of the budget balance and its composition ii are there certain institutional reforms that one should feel comfortable in recommending based on the relatively scarce empirical evidence available we tentatively answer yes to the first question budget procedures matter on the second question we suggest that the two critical areas of reform are first more transparency second a strengthening of the roles of the executive branch vis a vis the legislature and of the treasury minister vis a vis the rest of the executive branch in order to achieve a centralized and top bottom approach to the budget process

asset pricing implications of a new keynesian model to match the stylised facts of goods and labour markets the canonical new keynesian model augments the optimising neoclassical growth model with nominal and real rigidities we ask what the implications of this type of model are for asset prices using a second order numerical solution to the model we examine bond and equity returns the equity risk premium and the behaviour of the real and nominal term structure we catalogue the factors that are most important for determining the size of risk premia and the slope and level of the yield curve in a world of technology shocks only increasing the degree of real rigidities raises risk premia and increasing nominal rigidities reduces risk premia in a world of monetary policy shocks only both real and nominal rigidities raise risk premia the results indicate that the implications of the new keynesian model for average asset returns depend critically on the

using asset prices to measure the persistence of the marginal utility of wealth we derive a lower bound for the volatility of the permanent component of investors marginal utility of wealth or more generally asset pricing kernels the bound is based on return properties of long term zero coupon bonds risk free bonds and other risky securities we find the permanent component of the pricing kernel to be very volatile its volatility is about at least as large as the volatility of the stochastic discount factor a related measure for the transitory component suggest it to be considerably less important we also show that for many cases where the pricing kernel is a function of consumption innovations to consumption need to have permanent effects

the local recoverability of risk aversion and intertemporal substitution abstract call an economy revealing if underlying preferences are recoverable from asset prices specifically from the prices of aggregate equity or a one period discount bond in a lucas econometrica 46 1978 1429 4444 model with kreps porteus econometrica 46 1978 185 200 nonexpected utility and markov output growth rate process local recoverability is shown to be a generic property in this sense it is generically true that asset pricing models based on the more general kreps porteus utility have more explanatory power than the usual expected utility and both the risk aversion and intertemporal aspects of the kreps porteus utility can be recovered from a single dynamic equilibrium journal of economic literature classification numbers d11 g12 c60 d50 d80

disasterization a simple way to fix the asset pricing properties of macroeconomic models a central difficulty in economics is to create a model with both good business cycle properties and asset pricing properties i show how to solve this difficulty by a simple portable modeling device the disasterization of models take an economy with good business cycle properties and create a new disasterized economy which is essentially identical to the original one except that disasters can destroy part of the capital stock and productivity in such a disasterized economy asset prices exhibit high and volatile risk premia but macro variables remain unchanged perturbations of this benchmark allow for feedback from finance to macro

dynamic analysis of an endogenous growth model with public capital this paper develops an endogenous growth model with productive public capital along with private capital in a spirit similar to that of r j barro 1990 since the authors model includes two stock variables it has transitional dynamics unlike most of the previous studies on endogenous growth including barro s where concerns are restricted to the steady state analysis first they show that the transitional path is unique and stable second the character of the transitional path is explored third the authors show that the optimal tax rate is smaller than the rate that maximizes the national growth rate with a log linear utility function copyright 1993 by the editors of the scandinavian journal of economics
