Evaluation of national science park systems: a theoretical framework and its application to the Italian and Spanish systems

Although many authors have analysed the role and the efficiency of science parks, only a few contributions have analysed national science park systems (SPSs) as a whole. Because of the lack of data, evidence regarding the performance of science parks in a nation is very limited and there is a lack of comparisons between different systems. This paper aims to introduce a simple framework to analyse SPSs and to show its use for comparing the state of development and the main differences of two or more SPSs. Its application to the Italian and Spanish systems shows that science parks play a more important role in Spain than in Italy. The main causes of these differences are argued to be (i) the presence of a set of coherent and particular policies which favour science parks in Spain and (ii) the internal factors of the Spanish science park system, including business models of the science parks and the role of the national association.     

The influence of strategic dimensions and the environment on the introduction of internet as innovation into small and medium-sized enterprises

The expansion of the Internet has been spectacular, but only limited research has analysed how environmental and strategic variables simultaneously influence its organisational implementation and how small firms decide to adopt the use of the Internet. This study simultaneously examines the influence of three environmental dimensions (hostility, complexity and dynamism), and the three strategic dimensions (entrepreneurial, technological and administrative), upon the decision to introduce the use of the Internet into small business enterprises. We base our conclusions upon the data obtained from interviews with the managers of a sample of 94 small and medium-sized Spanish enterprises. Our results support a multidimensional view of environmental and strategic characteristics and show that all these variables constitute significant factors in deciding whether to introduce the Internet into company use. Logistic regression also shows the greater influence exerted by internal (strategic) factors and size rather than by environmental factors.     

Ownership structure and diversification in a scenario of weak shareholder protection

This work examines the influences of ownership concentration and insider ownership on corporate strategies for diversification within a scenario characterized by poor protection of shareholder interests. We find evidence of a quadratic relationship between ownership concentration and diversification, and a cubic relationship between diversification and insider ownership. These results point towards the high probability of both expropriation and entrenchment phenomena, respectively, in this kind of scenario. We also find that concentrated ownership requires high levels of insider ownership, in order to prevent negative externalities of diversification. Another result shows that entrenchment externalities affect diversification before they erode firm value, which suggests that for low levels of diversification, firm value is still not negatively affected. Additionally, our results show that control mechanisms, such as debt, director remuneration and compliance with codes of good practice, are negatively related to the level of diversification. Overall, our results confirm the theoretical relevance of agency theory in explaining managerial attitudes towards corporate strategy, i.e. diversification. Furthermore, companies characterized by deficiencies in shareholder legal protection, concentrated ownership structures and a higher likelihood of managers being entrenched, should focus on the correct functioning of corporate governance mechanisms.     

Average Internal Rate of Return and Investment Decisions: A New Perspective

The internal rate of return (IRR) is often used by managers and practitioners for investment decisions. Unfortunately, it has serious flaws: (1) multiple real-valued IRRs may arise; (2) complex-valued IRRs may arise; (3) the IRR is, in general, incompatible with the net present value (NPV) in accept/reject decisions; (4) the IRR ranking is, in general, different from the NPV ranking; (5) the IRR criterion is not applicable with variable costs of capital. The efforts of economists and management scientists in providing a reliable project rate of return have generated over the decades an immense bulk of contributions aiming to solve these shortcomings. This article offers a complete solution to this long-standing unresolved issue by changing the usual perspective: the IRR equation is dismissed and the evaluator is allowed to describe the project as an investment or a borrowing at his discretion. This permits showing that any arithmetic mean of the one-period return rates implicit in a project reliably informs about a project's profitability and correctly ranks competing projects. With such a measure, which we call average internal rate of return, complex-valued numbers disappear and all the above-mentioned problems are wiped out. The economic meaning is compelling: it is the project return rate implicitly determined by the market. The traditional IRR notion may be found as a particular case.     

Endogeneity and sample selection in a model for remittances

We estimate a remittance model in which we address endogeneity and reverse causality relationships between immigrants' remittances, pre-transfer income and consumption. In order to take into account the fact that a large share of individuals do not remit, instrumental variable variants of the double-hurdle and Heckit selection models are proposed and estimated by Limited Information ML; semiparametric extensions are considered as robustness checks. Our results for a sample of recent immigrants to Australia show that endogeneity is substantial and that estimates obtained by the methods previously employed in the literature may be misleading if given a behavioral interpretation.     

Genetic multi-model composite forecast for non-linear prediction of exchange rates

The existence of non-linear deterministic structures in the dynamics of exchange rates has already been amply demonstrated. In this paper, we attempt to exploit these non-linear structures employing forecasting techniques, such as Genetic Programming and Neural Networks, in the specific case of the Yen/US$ and Pound Sterling/US$ exchange rates. Forecasts obtained from genetic programming and neural networks are then genetically fused to verify whether synergy provides an improvement in the predictions. Our analysis considers both point predictions and the anticipating of either depreciations or appreciations.First version received: July 2003 / Final version received: June 2004We wish to thank Pacific Exchange Rate Service for providing us the data.     

The contingent influence of organizational capabilities on proactive environmental strategy in the service sector: An analysis of North American and European ski resorts

Our study of 134 North American and European ski resorts examines the influence of externally focused organizational capabilities on the generation of proactive environmental strategies under contingent effects of uncertainty in the general business environment. We find that the capabilities of strategic proactivity and continuous innovation are associated with proactive environmental strategies. Managerial perceptions of uncertainty in the general business environment moderate the deployment of the capability of continuous innovation at all levels of uncertainty and stakeholder engagement at low and average levels of uncertainty. The study contributes to the resource‐based view (RBV) by illuminating an important contingency under which capabilities are likely to be deployed to generate a proactive corporate strategy.

Airline competition in the British Isles

We study the relationship between pricing and market structure on the routes connecting the UK and the Republic of Ireland. Because in 2007 the European Commission prohibited the takeover of Aer Lingus by Ryanair, the analysis focuses on their pricing strategies in particular. We use an original dataset of fares posted on-line, which allows to control for the fares’ inter-temporal pattern for each specific flight and each carrier’s specific yield management system. Our evidence supports the European Commission’s view that the elimination of a competitor in the Irish airline market is likely to have harmful consequences for consumers.
