Ideational item Avoiding the pitfalls of managementThink

Productive, structured, and efficient thinking is often the only kind encouraged by companies—at least, until they notice that such thinking can harden into unimaginative and rigid patterns. Every manager and every company needs to take time to try out new thinking patterns and look at possibilities in new ways.     

Dynamic common factors in large cross-sections

This paper develops a method to analyze large cross-sections with non-trivial time dimension. The method (i) identifies the number of common shocks in a factor analytic model; (ii) estimates the unobserved common dynamic component; (iii) shows how to test for fundamentalness of the common shocks; (iv) quantifies positive and negative comovements at each frequency. We illustrate how the proposed techniques can be used for analyzing features of the business cycle and economic growth.     

Index futures trading and stock price volatility: Evidence from Denmark and France

This study uses an EGARCH methodology to investigate the impact of index futures trading on the price volatility of two European stock markets. The results show that index futures trading has changed the distribution of stock returns in Denmark and France, however, it has not increased stock price volatility. There is evidence that futures trading has dampened stock price fluctuations in France. The results further show that stocks in Denmark and France exhibit strong volatility persistence and asymmetry, especially during the post-futures period.     

Foreign exchange market regularities in a developing economy

The purpose of this paper is to demonstrate that the ‘empirical regularities’ observed for exchange rates in the major foreign exchange markets apply equally to the case of a developing economy such as Singapore.     

Innovation and Productivity in European Industries

The labour productivity impact of innovation is investigated in this paper combining neo-Schumpeterian insights on the variety of innovation with the importance of industrial structures and firm size; two models are proposed for explaining productivity and export success in European manufacturing industries and firm-size classes. The empirical estimates are based on data from the European innovation survey (CIS 2), covering Austria, France, Italy, the Netherlands, and the UK, broken down by 22 sectors and for large, medium, and small firms. The econometric results, obtained adopting cross-sectional estimation methodologies able to account for unobserved industrial characteristics, show that productivity in Europe relies on product and process innovation, with the support of the efficiency gains provided by grouped business structures. Conversely, in Italy the introduction of new machinery linked to innovation appears as the key mechanism supporting domestic productivity. When export success is considered, all countries have to rely on an innovation-based model of competitiveness.     

A copula-VAR-X approach for industrial production modelling and forecasting

World economies, and especially European ones, have become strongly interconnected in the last decade and a joint modelling is required. We propose here the use of copulae to build flexible multivariate distributions, since they allow for a rich dependence structure and more flexible marginal distributions that better fit the features of empirical data, such as leptokurtosis. We use our approach to forecast industrial production series in the core European Monetary Union (EMU) countries and we provide evidence that the copula-Vector Autoregression (VAR) model outperforms or at worst compares similarly to normal VAR models, keeping the same computational tractability of the latter approach.
