A new semiparametric estimator for an empirical asset pricing model with general nonparametric risk-return tradeoff and a GARCH process for the underlying volatility is introduced. The estimator does not rely on any initial parametric estimator of the conditional mean function, and this feature...

In this paper a new GARCH–M type model, denoted the GARCH-AR, is proposed. In particular, it is shown that it is possible to generate a volatility-return trade-off in a regression model simply by introducing dynamics in the standardized disturbance process. Importantly, the volatility in the...

inflation should move one for one in the long run, and, hence, inflation should be predictable by money growth. The model fits … postwar U.S. data well, and beats common univariate benchmark models in forecasting inflation. Moreover, this evidence is … quite robust, and predictability is found also in the Great moderation period. The detected predictability of inflation by …

With … this model we decompose the inflation process into a slowly moving nonstationary component and dynamic short …-run fluctuations around it. We fit the model to the monthly euro area, UK and US inflation series. An important feature of our model is …

We apply the methods to postwar quarterly U.S. inflation and … future distribution of inflation over and above the own history of inflation, but not vice versa. This may be interpreted as … evidence against the new Keynesian model that implies Granger causality from inflation to GDP growth, provided GDP growth is a …

Disagreement in inflation expectations observed from survey data varies systematically over time in a way that reflects … the level and variance of current inflation. This paper offers a simple explanation for these facts based on asymmetries … in the forecasters’ costs of over- and under-predicting inflation. Our model implies (i) biased forecasts; (ii) positive …

We consider hypothesis testing in a general linear time series regression framework when the possibly fractional order of integration of the error term is unknown. We show that the approach suggested by Vogelsang (1998a) for the case of integer integration does not apply to the case of...

We introduce the Realized Exponential GARCH model that can utilize multiple realized volatility measures for the modeling of a return series. The model specifies the dynamic properties of both returns and realized measures, and is characterized by a flexible modeling of the dependence between...
