Most rational expectations models involve equations in which the dependent variable is a function of its lags and its expected future value. We investigate the asymptotic bias of generalized method of moment (GMM) and maximum likelihood (ML) estimators in such models under misspecification. We...

The paper investigates the properties of a portfolio composed of a large number of assets driven by a strong multivariate GARCH(1,1) process with heterogeneous parameters. The aggregate return is shown to be a weak GARCH process with a (possibly large) number of lags, which reflect the moments...

The "New Keynesian" Phillips Curve (NKPC) states that inflation has a purely forward-looking dynamics. In this paper, we test whether European and US inflation dynamics an be described by this model. For this purpose, we estimate hybrid Phillips curves, which include both backward and...

Estimating a forward-looking monetary policy rule by the Generalized Method of Moments (GMM) has become a popular approach since the influential paper by Clarida, Gali, and Gertler (1998). However, an abundant econometric literature underlines to the unappealing small-samples properties of GMM...

Environmental, Social, and Governance (ESG) scores are the main tool for asset managers in designing and implementing ESG investment strategies. They amalgamate a broad range of fundamentally different factors, creating ambiguity for investors as to the signals of higher or lower ESG scores. We...
