Deposition of silicon dioxide (SiO2) is a critical step of integrated circuit manufacturing; hence it is monitored during the manufacturing process at a grid of points defined on the wafer area. Since collecting thickness measurements is expensive, it is a compelling issue to investigate how a...

This paper presents an efficient method to compute portfolio risk and return. Two methodologies are exposed in evaluating portfolio performance by aggregation of securities returns: the first one is based on local approximations of the compounding capitalization formula; in the alternative...

Purpose – The paper is aimed at modelling time varying betas via a state space representation in order to decompose the marginal contribution to risk of downside and upside deviations of asset returns in portfolio optimisation. Design/methodology/approach - The approach enables to take into...

The European Union's Markets in Financial Instruments Directive (MiFID), that will be implemented by October 2007, significantly modifies the regulation of the European securities industry. It will allow, among other things, investment firms to act as systematic internalizers. A systematic...

In this paper we perform regression-based tests for mean-variance spanning in order to detect the effect of investing in euro area small capitalization stocks on the minimum variance frontier, and apply different measures to assess the extent of diversification gains. Empirical analysis shows...

This paper addresses the issue of the optimal trading system for less actively traded stocks. Several studies have examined the quality and performance of alternative market structures for actively traded stocks. However, very few empirical studies compare the performance of different market...

This paper develops and empirically tests a simple market microstructure model to capture the main determinants of option bid-ask spread. The model is based on option market making costs (initial hedging, rebalancing, and order processing costs), and incorporates a reservation bid-ask spread...

Although MiFID and Reg NMS share the common objective of enhancing competition in securities markets, they differently regulate the best execution duty, the consolidation of market data and the publication of execution quality information. These differences are particularly relevant since they...
