Testing Homogeneity and Unit Root Restrictions in Panels

Popular Abstract in Swedish Denna avhandling består av sex kapitel. Det första kapitlet är en introduktion medan de resterande fem innehåller avhandlingens huvudsakliga bidrag. De tre första kapitlen är samförfattade med Joakim Westerlund. Kapitel två har sin utgångspunkt i Westerlund (Empirical Economics 37:517-531, 2009) som visar på en svaghet i det populära LLC (Levin et al. Journal of EconomThis thesis is divided into two distinct parts. The first part contains three chapters, co-authored with Joakim Westerlund, that deal with the analysis of unit root testing, and the second part consists of two chapters on slope homogeneity testing. Chapter 2 continues and extends the analysis in Westerlund (Empirical Economics 37:517–531, 2009), who demonstrates that the performance of the popula

Trust and Brand Recovery Campaign in Crisis: Findus Nordic and the Horsemeat Scandal

The aim of this paper is to describe and analyze a transboundary crisis, focusing crisis communication, from the perspective of an involved major corporation. More concretely the intent is to increase under-standing of how Findus Nordic in Sweden managed the crisis communication response and repair of it´s corporate brand during and after the horesemeat scandal in 2013. The case study is founded i

Improved design and performance of an acoustically operated multi channel particle separation chip

An improved design for acoustic particle separation in multichannel chips is presented. By wavelength matching of the microfluidic channel widths and the width of the interlacing bulk silicon, a well tuned resonating multilayer system can be accomplished. The acoustically tuned microchip offers considerable improvements in regards to particle focusing performance, i.e. separation efficiency, at fi
