Real exchange rates and economic fundamentals : an investigation based on a Markov-STAR model

Bertram, Philip; Ma, Jun; Sibbertsen, Philipp - 2015

In this paper we introduce a new nonlinear Markov-STAR model to capture both the markov switching and smooth transition dynamics for real exchange rates. The Markov switching part captures the effect of time variations of the equilibrium exchange rates, while the smooth transition part models...

The effects of variance breaks on homogenous panel unit root tests

Herwartz, Helmut; Siedenburg, Florian - 2009

Noting that many economic variables display occasional shifts in their second order moments, we investigate the performance of homogenous panel unit root tests in the presence of permanent volatility shifts. It is shown that in this case, panel unit root tests derived under time invariant...

An empirical study on causes and consequences of inflation and inflation uncertainty

Hartmann, Matthias - 2012

Empirical study of causality between inflation, inflation uncertainty and other macroeconomicy quantities. Additionally, the issue of how to measure the unobservable inflation uncertainty is addressed.

The dynamics of real exchange rates : a reconsideration

Heinen, Florian; Kaufmann, Hendrik; Sibbertsen, Philipp - 2011

While it is widely agreed that Purchasing Power Parity (PPP) holds as a long-run concept the specific dynamic driving the process is largely build upon a priori economic belief rather than a thorough statistical modeling procedure. The two prevailing time series models, i.e. the exponential...

State dependence in the finance-growth nexus : a functional coefficient approach

Herwartz, Helmut; Yabibal Mulualem Walle - 2013

Noting that "one size does not fit all" in the case of the finance-growth (FG) nexus, a growing body of literature has recently focused on uncovering economic conditions under which financial development could be beneficial (detrimental) to economic development. We look into these conditions by...

A new approach to bootstrap inference in functional coefficient models

Herwartz, Helmut (contributor); Fang, Xu (contributor) - 2007

We introduce a new, factor based bootstrap approach which is robust under heteroskedastic error terms for inference in functional coefficient models. Modeling the functional coefficient parametrically, the bootstrap approximation of an F statistic is shown to hold asymptotically. In simulation...

The long memory of equity volatility and the macroeconomy : international evidence

Dräger, Lena; Nguyen, Duc Binh Benno; Prokopczuk, Marcel; … - 2020

This paper examines long memory volatility in international stock markets. We show that long memory volatility is widespread in a panel dataset of eighty-two countries and that the degree of memory in the panel can be related to macroeconomic variables such as short- and long-run interest rates...

The long memory of equity volatility : international evidence

Nguyen, Duc Binh Benno; Prokopczuk, Marcel; Sibbertsen, … - 2017

This paper examines long memory volatility in international stock markets. We show that long memory volatility is widespread in eighty-two countries and that the degree of memory can be related to macroeconomic variables such as inflation, unemployment rates, interest rates or stability of a...

Skill policies for Scotland

Heckman, James J. (contributor); … - 2004

This paper argues that skill formation is a life-cycle process and develops the implications of this insight for Scottish social policy. Families are major producers of skills, and a successful policy needs to promote effective families and to supplement failing ones. We present evidence that...
