Small firms and technological development in the food processing machinery industry: The case of pasta and other cereal derivative machines in Italy

This study about Italian producers of machines and plants for pasta, basic cereals, snacks and bread factories attempts to shed some light on the role played by small and medium-sized enterprises (SMEs) in the Italian industry. Even if the high diffusion of SMEs has positively affected the performance of Italian economy during the seventies and the eighties, the new trends of technological change and global competition are expected to be unfavourable to this category of enterprises in the nineties. The analyses of a significant sample of firms makes clear that the industry is in the middle of a positive restructuring process. The structure of this sector shows a division of labour based on deverticalization of production, and a process of internationalization focused on exports and not on direct investments or joint ventures abroad. Leading firms are following growth strategies by new investments and acquisitions. Finally, as far as technological change is concerned, there is a significant increase of process innovations, thanks to the use of electronic components.An earlier release of this paper was presented at 7th EARIE (European Association for Research in Industrial Economics) Annual Conference in Lisbon, September 2–4 1990.

Testing weak form efficiency on the Toronto Stock Exchange

In order to test for weak form efficiency in the market a vast pool of individual stocks must be analyzed rather than a stock market index. In this paper, a model-based bootstrap is used to generate a series of simulated trials and a modified chart pattern recognition algorithm is applied to all stocks listed on the Toronto Stock Exchange (TSX). The number of patterns detected in the original price series is compared with the number of patterns found in the simulated series. By simulating the price path specific time dependencies present in real data are eliminated, making price changes purely random. Patterns, if consistently identified, carry information which adds value to the investment process, however, this informativeness does not guarantee profitability. Conclusions are drawn on the relative efficiency of some sectors of the economy. Although the null hypothesis of weak form efficiency on the TSX cannot be rejected, some sectors of the Canadian economy appear to be less efficient than others. In addition, pattern frequencies appear to be negatively dependent on the two moments of return distributions, variance and kurtosis.     

Insider employee stock option trading and stock prices

The question of which factors determine corporate bonds pricing is investigated by analysing the spreads of eurobonds issued by major G-10 companies during the 1991–2001 period. Three main results emerge from the analysis. First, bond ratings appear as the most important determinant of yield spreads, with investors’ reliance on rating agencies judgments increasing over time. Second, the primary market efficiency and the expected secondary market liquidity are not relevant explanatory factors of spreads cross-sectional variability. Finally, rating agencies adopt a different, ‘through the cycle’, evaluation criteria of default risk with respect to the forward looking one adopted by bond investors.
