Disentangling the effects of organizational capabilities, innovation and firm size on SME sales growth

Abstract: This paper focuses on certain drivers of SME sales growth related to knowledge and innovation. Building on the dynamic capabilities literature, we test whether two organizational capabilities (external sourcing and employee involvement in renewal activities) predict sales growth, and if so, whether such effects are mediated by process and/or product innovation. Based on survey data from a panel study of Dutch SMEs, and controlling for several firm characteristics (firm size, sector, age and family business), we conclude that external sourcing has direct effects on both product and process innovation, with an indirect effect (mediated by process innovation) on sales growth. In line with our hypothesis development, we also find that employee involvement, while positively affecting process innovation, has a negative effect on sales growth. Firm size moderates the effects of two of the variables (external sourcing and product innovation) on sales growth, with more positive effects found for the smallest firms, results supporting the nimbleness (versus resource-based) view.

Improving Portfolio Selection Using Option-Implied Volatility and Skewness

Abstract: Our objective in this paper is to examine whether one can use option-implied information to improve the selection of mean-variance portfolios with a large number of stocks, and to document which aspects of option-implied information are most useful for improving their out-of-sample performance. Portfolio performance is measured in terms of volatility, Sharpe ratio, and turnover. Our empirical evidence shows that using option-implied volatility helps to reduce portfolio volatility. Using option-implied correlation does not improve any of the metrics. Using option-implied volatility, risk-premium, and skewness to adjust expected returns leads to a substantial improvement in the Sharpe ratio, even after prohibiting shortsales and accounting for transactions costs.
