Can we measure Microsoft's market power ?
This paper has the objective of measuring the market power of Microsoft in the software industry. We develop a two tier arguent. Firstly we estimate the scale economies within the industry. We then make the crude hypothesis that a firm's success in this industry is linked to its size, based on the scale argument. We modelise these assumptions and then compare the expected profits and actual profits genereted by Microsoft. The results tend to show that Microsoft has posted profits in excess of those that such a firm is expected to benefit from if it does not have market power.
Evidence of spurious results along with spatially autocorrelated errors in the context of geographically weighted regression for two independent SAR(1) processes
AbstractThe aim of this paper is to examine the performance of the geographically weighted regression (GWR) technique in terms of recognizing linear relationships at the local level. Using a Monte Carlo analysis with two independent spatially autocorrelated SAR(1) processes, this study finds that spurious behavior exists at the local level along with spatially autocorrelated errors. Therefore, GWR estimation results must be interpreted with caution.
