Regional Economic Transformation: The role of clusters in specialised diversification

Paton, Jonatan; Castillo, Jaime Del; Barroeta, Belen - 2014

Regarding context conditions and the role of territories on competitiveness and innovation, clusters have become progressively a spreading phenomenon all around the world. Recently, the importance of clusters has been mixed with the concept of smart specialization, a territorial development...

On spectral distribution of high dimensional covariation matrices

Heinrich, Claudio; Podolskij, Mark - School of Economics and Management, University of Aarhus - 2014

In this paper we present the asymptotic theory for spectral distributions of high dimensional covariation matrices of Brownian diffusions. More specifically, we consider N-dimensional Itô integrals with time varying matrix-valued integrands. We observe n equidistant high frequency data points...

Parameter Estimation and Model Testing for Markov Processes via Conditional Characteristic Functions

Chen, Songxi; Peng, Liang; Yu, Cindy - Volkswirtschaftliche Fakultät, … - 2013

Markov processes are used in a wide range of disciplines, including finance. The transition densities of these processes are often unknown. However, the conditional characteristic functions are more likely to be available, especially for Lévy-driven processes. We propose an empirical likelihood...

Edgeworth expansion for functionals of continuous diffusion processes

Podolskij, Mark; Yoshida, Nakahiro - School of Economics and Management, University of Aarhus - 2013

Edgeworth expansion for power variation of diffusion processes. Our methodology relies on martingale embedding, Malliavin …This paper presents new results on the Edgeworth expansion for high frequency functionals of continuous diffusion … processes. We derive asymptotic expansions for weighted functionals of the Brownian motion and apply them to provide the …

Structural Reforms and Regional Convergence

Spilimbergo, Antonio; Che, Natasha Xingyuan - International Monetary Fund (IMF) - 2012

Which structural reforms affect the speed the regional convergence within a country? We found that domestic financial development, trade/current account openness, better institutional infrastructure, and selected labor market reforms facilitate regional convergence. However, these reforms have...
