Robust small area estimation under spatial non-stationarity
Baldermann, Claudia; Salvati, Nicola; Schmid, Timo - 2016
Geographically weighted small area methods have been studied in literature for small area estimation. Although these approaches are useful for the estimation of small area means efficiently under strict parametric assumptions, they can be very sensitive to outliers in the data. In this paper, we...

High-tech left behind? : lessons from the Ruhr cybersecurity ecosystem for approaches to develop "left behind" places
Butzin, Anna; Flögel, Franz - 2022
The attention to "left behind" places triggered a debate about alternative development approaches. Unlike prosperous regions and their prioritisation on high-tech sectors, strategies for left behind places should shift to the foundational economy, community-based social innovation and...

The role of industrial sector in the Brazilian territorial reconfiguration : new expressions for XXI century national dilemmas
Monteiro Neto, Aristides; Silva, Raphael de Oliveira; … - 2022
In this article, we discuss the current pattern of territorial reconfiguration of the Brazilian industry, its current forms, and motivations in order to problematize some of the most significant challenges of the current regional issue. We have brought new evidence of how it keeps...

Identifying time variability in stock and interest rate dependence
Stein, Michael; Islami, Mevlud; Lindemann, Jens - 2012
The correlation between stock markets and interest rates has been discussed in numerous studies in the past, with … which allow for time-variability and regime changes in correlation. All estimated models allowing for timevarying … correlation complement each other in identifying time-varying patterns found in the (co-)movement between the variables …

Analyzing business and financial cycles using multi-level factor models
Breitung, Jörg; Eickmeier, Sandra - 2014
This paper compares alternative estimation procedures for multi-level factor models which imply blocks of zero restrictions on the associated matrix of factor loadings. We suggest a sequential least squares algorithm for minimizing the total sum of squared residuals and a two-step approach based...

Do correlated defaults matter for CDS premia? : an empirical analysis
Koziol, Christian; Koziol, Philipp; Schön, Thomas - 2014
Correlated defaults and systemic risk are clearly priced in credit portfolio securities such as CDOs or index CDSs. In this paper we study an extensive CDX data set for evidence whether correlated defaults are also present in the underlying CDS market. We develop a cash flow based top-down...

Inference on the maximal rank of time-varying covariance matrices using high-frequency data
Reiß, Markus; Winkelmann, Lars - 2021
We study the rank of the instantaneous or spot covariance matrix Σ(t) of a multidimensional continuous semi-martingale X(t). Given highfrequency observations X(i=n), i = 0; : : : ;n, we test the null hypothesis rank (Σ(t)) ≤ r for all t against local alternatives where the average (r + 1)st...
