Abstract [en]

For some time now, the research focusing on Knowledge Intensive Business Services (KIBS) has been very active. Observing that knowledge as a production factor is only becoming more and more pronounced, this focus is well-grounded. It is therefore important to examine how these knowledge-hubs gain and propagate their knowledge. We hypothesize that KIBS (as many other sectors) benefit from intra-industry knowledge spillovers facilitated by geographical concentration. Our focus is the innovative capacity of KIBS, which we measure through trademarks registered by KIBS firms. While there may be several mechanisms facilitating knowledge spillovers, we can identify local intra-sectoral labor mobility as one. Accessibility measures are used to assess the geographical attenuation of the spillover effects. Results show that the distance decay of spillovers is fast. Only local concentrations of KIBS seem to be of importance. Over longer distances, we instead observe negative consequences for trademarking, indicating possible spatial competition effects.

Abstract [en]

This paper argues that traditional measures of innovation as a univariate phenomenon may not be dynamic enough to adequately describe the complex nature of innovation. Consequently, the purpose is to develop a multidimensional index of innovation that is able to reflect innovation enablers and outputs. The index may then be used (i) to assess and quantify temporal changes of innovation, (ii) to describe regional differences and similarities of innovation, and (iii) serve as exogenous variables to analyze the importance of innovation for other economic phenomena. Our index is defined in a four-dimensional space of orthogonal axes. An empirical case study is used for demonstration of the index, where 44 variables are collected for all municipalities in Sweden. The index spanning the four-dimensional innovation comprises size, accessibility, firm performance, and agglomeration. The proposed index offers a new way of defining and analyzing innovation and should have a wide range of important applications in a world where innovation is receiving a great deal of recognition.

Abstract [en]

Urbanization and new digital technologies have significantly altered the news media industry. One major change is the disappearance of local editorial offices in many regions. This paper examines if there is a relation between access to local media in terms of editorial offices and journalists, and the likelihood of the public consuming local news. The study builds on fine level data for Sweden in 2006 and in 2013, allowing for a comparison of trends. Our results suggest that the existence of an editorial office in the municipality is not significantly related to the consumption of local newspapers but that accessibility to employed journalists who live in the municipality is.

Abstract [en]

In this article, the Scandinavian housing financing market is analysed in order to determine whether the interest rate price-discovery processes of Denmark, Norway and Sweden are efficient. Based on wavelet quantile regression analysis, we find systematic positive asymmetric price transmission (APT) inefficiencies. We conclude that there is a very high propensity for mortgage lenders to directly increase its customers’ mortgage interest rates subsequently to an increase in its borrowing costs. However, after a corresponding borrowing cost decrease, the same mortgage lenders are very slow to decrease its customers’ mortgage rates. These positive coefficients for so-called APT effects are found in all Scandinavian countries, even if the coefficients for Norway were not statistically significant. Wavelet quantile regression analysis, with a focus on the relevant higher percentiles, is easily motivated since the mortgage rates are adjusted very infrequently. Moreover, wavelet decomposition allows a robust analysis at different time frequency scales, while simultaneously controlling for nonstationary trends, autocorrelation and structural breaks. Except for the still positive but yet insignificant and inconclusive coefficients for Norway, the result is very clear-cut. Regardless of which wavelet scaling decomposition or quantile coefficient that is studied – positive APT effects are clearly identified and confirmed on the Scandinavian mortgage market.
