Innovation networks: from technological development to business model reconfiguration
2007-08This case study presents an example of how a technological innovation network provides the necessary resources to change the business model, in order to achieve global competitiveness. It describes the R&D investments of ... -
A theory of capital gains taxation and business turnover
2007-09We present a theory concerning the realization of capital gains where ownership and control are linked as in Holmes and Schmitz (J. Pol. Econ. 103: 1005-1038, 1995). The model developed is a version of a Lucas-tree economy ... -
Perfectly random sampling of truncated multinormal distributions
2007-12The target measure mu is the distribution of a random vector in a box B, a Cartesian product of bounded intervals. The Gibbs sampler is a Markov chain with invariant measure mu. A 'coupling from the past' construction of ... -
Understanding our understanding of strategic scenarios: what role do chunks play?
2007-12There is a crucial debate concerning the nature of chess chunks: One current possibility states that chunks are built by encoding particular combinations of pieces-on-squares (POSs), and that chunks are formed mostly by ... -
Storytellers and their discursive strategies in a post-acquisition process
2008Purpose - The aim is to discuss how storytelling can be used in different ways to enlighten change processes occurring within and after a takeover situation. Design/methodology/approach - Case study reseach based on in-depth ... -
Hysteresis vs. natural rate of unemployment in Brazil and Chile
2008This article examines the hysteresis hypothesis in the unemployment rates of Brazil and Chile using an LM unit root test with two endogenous breaks. The phenomenon is confirmed for both countries. However, the hysteresis ... -
Public management in South America: what happened in the last ten years?
2008There has been a global movement that has changed the nature of the state and its administration. Reforms have been implemented in Brazil, as they have in many other countries. This article aims to examine some profound ... -
Writing the lines of connection: unveiling the strange language of urbanization
2008Across urban studies there is an increasing preoccupation with the forms of articulation that link a multiplicity of cities across a region often known as the 'Global South'. How do cities such as Jakarta, Sao Paolo, Dakar, ... -

Term structure movements implicit in Asian option prices
2008In this paper we implement dynamic term structure models that adopt bonds and Asian options in the estimation process. The goal is to analyse the pricing and hedging implications of term structure movements when options ... -
Area distances of convex plane curves and improper affine spheres
2008The area distance to a convex plane curve is an important concept in computer vision. In this paper we describe a strong link between area distances and improper affine spheres. Based on this link, we propose an extremely ... -
Industrial policy changes and firm-level technological capability development: evidence from Northern Brazil
2008-01Much has been written about the impacts of the policy changes of the 1990s on industrial performance, particularly in Latin America. Most of the studies are based on aggregated analyses that argue for or against such reforms ... -
A fast marching method for the area based affine distance
2008-01In a previous paper, it was proved that the area based affine distance of a convex region in the plane satisfies a non-homogeneous Monge-Ampere differential equation. Based on this equation, in this paper we propose a fast ... -
