We show that the S&P 500's instantaneous response to surprises in U.S. macroeconomic announcements depends on the level of long-term stock market volatility. When long-term volatility is high, stock returns are more sensitive to news, and there is a pronounced asymmetry in the response to good...

Macroeconomic expectations of various economic agents are characterized by substantial cross-sectional heterogeneity. In this paper, we focus on expectations heterogeneity among professional forecasters. We first present stylized facts and discuss theoretical explanations for heterogeneous...

This paper employs an augmented version of the UECCC GARCH specificationproposed in Conrad and Karanasos (2010) which allows for lagged in-mean effects,level effects as well as asymmetries in the conditional variances. In this unifiedframework we examine the twelve potential intertemporal...

In a simple New Keynesian model, we derive a closed form solution for the inflationpersistence parameter as a function of the policy weights in the central bank’s Taylorrule. By estimating the time-varying weights that the FED attaches to inflationand the output gap, we show that the...

In this paper we model the adjustment process of European Union Allowance(EUA) prices to the releases of announcements at high-frequency controlling forintraday periodicity, volatility clustering and volatility persistence. We ¯nd thatthe high-frequency EUA price dynamics are very well captured...

This paper employs the unrestricted extended constant conditional correlationGARCH specification proposed in Conrad and Karanasos (2008) to examine theintertemporal relationship between the uncertainties of in°ation and output growthin the US. We find that inflation uncertainty effects output...

Tse (1998) proposes a model which combines the fractionally integrated GARCH formulationof Baillie, Bollerslev and Mikkelsen (1996) with the asymmetric power ARCH specification of Ding,Granger and Engle (1993). This paper analyzes the applicability of a multivariate constant...

Die in den letzten Jahren stark gestiegene Inflation beschäftigt nicht nur die Währungshüter, sondern beunruhigt auch Verbraucher:innen und Politik. Der Europäischen Zentralbank wird vorgeworfen, mit ihren Inflationsprognosen in den Jahren 2021 und 2022 die tatsächliche Entwicklung deutlich...

This paper employs the unrestricted extended constant conditional correlation GARCH specification proposed in Conrad and Karanasos (2010) to examine the intertemporal relationship between the uncertainties of inflation and output growth in the US. We find that inflation uncertainty effects...

This paper empirically examines price formation in the European Union Emissions Trading Scheme (EU ETS). Our analysis shows that unexpected allocations of European Union Allowances (EUAs) lead to pronounced price reactions of the expected signs. Moreover, we find evidence that the adjustment of...
