Are semi-presidential constitutions bad for democratic performance?

Many countries since 1990 have adopted semi-presidential constitutions, which are often considered to be problematic, primarily because of the potential for conflict between the assembly-supported government and the popularly elected president. Such conflicts are said to lead to unstable governments, policy paralysis and the eventual undermining of the democratic regime. Using data for all parliamentary and semi-presidential democracies between 1946 and 2006, we examine the effect of semi-presidential constitutions on the duration of prime ministers’ tenure in office, government accountability with respect to economic outcomes, and democratic survival. We also examine (for a smaller sample of post-communist countries) the impact of these constitutions on the progress of structural reforms. We find that the observed higher instability of prime ministers in semi-presidential democracies is more due to the electoral system than to the presence of a popularly elected president. We also find that semi-presidential constitutions have little impact on the government’s accountability to economic outcomes and on the survival of democratic regimes. Finally, we find that neither a weak president nor a weak government is optimal for the progress of economic reforms in post-communist countries. Regarding economic reforms, the optimal allocation of constitutional powers between the president and the government grants both significant powers.     

Robots, genes and bytes: technology development and social changes towards the year 2020

Scientific and technological policy has become a key activity in contemporary societies. In this context we present different projections about the evolution of science and technology in the area of robotics and advanced automation, which in turn shapes the new possibilities and risks emerging in this area in the future. This goes hand-in-hand with an analysis of the interaction of such trajectories with the social context from which they emanate. This interaction reinforces the need for establishing the probable sequence of technological innovation; analysing the impacts on economy and society; and providing qualified information for decision-making, both in policy and business. In this article, we present the results of the prospective research carried out in the field of robotics and advanced automation, paying special attention to the transformation trends of organizations, and the integration of robots in daily life and leisure, and underscoring potential repercussions which may deserve more attention and further research.     

Reasons for management control systems adoption: Insights from product development systems choice by early-stage entrepreneurial companies

Recent theoretical and empirical work indicates that management control systems (MCS) are an important element in enhancing innovation. We extend this research thrust examining the adoption of MCS in product development, arguably one of the business processes where innovation plays a major role. Using a sample of 69 early-stage entrepreneurial companies, data are collected from questionnaires and interviews with each of the CEO, financial officer, and business development managers pertaining to product development MCS. We examine seven different systems: project milestones, reports comparing actual progress to plan, budget for development projects, project selection process, product portfolio roadmap, product concept testing process, and project team composition guidelines. We address three distinct questions: (1) What are the reasons-for-adoption of these systems? The nature of our sample allows us to trace back to the adoption point and develop a set of reasons-for-adoption from the analysis of the data. While MCS fulfill certain roles as described in the literature, these reasons-for-adoption are distinct from these roles. Results indicate that certain events lead managers to adopt these systems and address the challenges that they face. They include contracting and legitimizing the process with external parties and internal reasons-for-adoption such as managers’ background, learning by doing, need to focus the organization, or reaction to problems. (2) Are these reasons-for-adoption associated with differences across companies in the time from their founding date until these systems are adopted (time-to-adoption)? Prior research has looked at the covariance of various organizational variables with this timing; this study goes a step further by looking at the effect of different reasons-for-adoption on this timing. Our evidence finds an association between these two variables. (3) Are these reasons-for-adoption relevant to performance? We find that the reason-for-adoption is associated with the on-time dimension of product development performance.     

Networks of queues with infinite servers in each node applied to the management of a two echelons repair system

After a report of results about infinite servers queues, essentially on its busy period, a model is built, using networks of queues with infinite servers in each node, to study a two echelons repair system for example of a fleet of aircraft, shipping or trucks. The customers are the failures, and their service time is the time that goes from the instant at which they occur till they are completely repaired. The failing repairs occur in a base or in a remote station. The whole failures detected in the base are repaired there. Some of the failures detected in the station are repaired there and the others in the base. The results referred above allow the determination of a two echelons repair system performance measures. In this application, models of Carrillo （1991） and Ferreira （1996） are considered, improved and completed. The theory is illustrated with a numerical example.     

Formal vs. Informal CSR Strategies: Evidence from Italian Micro, Small, Medium-sized, and Large Firms

Recent research on corporate social responsibility (CSR) suggests the need for further exploration into the relationship between small and medium-sized enterprises (SMEs) and CSR. SMEs rarely use the language of CSR to describe their activities, but informal CSR strategies play a large part in them. The goal of this article is to investigate whether differences exist between the formal and informal CSR strategies through which firms manage relations with and the claims of their stakeholders. In this context, formal CSR strategies seem to characterize large firms while informal CSR strategies prevail among micro, small, and medium-sized enterprises. We use a sample of 3,626 Italian firms to investigate our research questions. Based on a multi-stakeholder framework, the analysis provides evidence that small businesses’ use of CSR, involving strategies with an important impact on the bottom line, reflects an attempt to secure their license to operate in the communities; while large firms rarely make attempts to integrate their CSR strategies into explicit management systems.     

The changing role of governments in corporate social responsibility: drivers and responses

The aim of this article is to contribute to understanding the changing role of government in promoting corporate social responsibility (CSR). Over the last decade, governments have joined other stakeholders in assuming a relevant role as drivers of CSR, working together with intergovernmental organizations and recognizing that public policies are key in encouraging a greater sense of CSR. This paper focuses on the analysis of the new strategies adopted by governments in order to promote, and encourage businesses to adopt, CSR values and strategies. The research is based on the analysis of an explanatory framework, related to the development of a relational analytical framework, which tries to analyze the vision, values, strategies and roles adopted by governments, and the integration of new partnerships that governments establish in the CSR area with the private sector and social organizations. The research compares CSR initiatives and public policies in three European countries: Italy, Norway and the United Kingdom, and focuses on governmental drivers and responses. The preliminary results demonstrate that governments are incorporating a common statement and discourse on CSR, working in partnership with the private and social sectors. For governments, CSR implies the need to manage a complex set of relationships in order to develop a win–win situation between business and social organizations. However, the research also focuses on the differences between the three governments when applying CSR public policies. These divergences are based on the previous cultural and political framework, such as the welfare state typology, the organizational structures and the business and social and cultural background in each country.     

A NON‐SUBSTITUTION THEOREM WITH NON‐CONSTANT RETURNS TO SCALE AND EXTERNALITIES

An input–output model with non‐constant returns to scale and externalities is presented, and it is shown that in this model the non‐substitution theorem is still valid. More precisely, the quantity side of the theorem, i.e. the proposition on efficiency, remains valid, while there can be no equilibrium prices independent of final demand.     

Firm efficiency,industry performance and the economy: three-way decomposition with an application to Andalusia

An economy may perform better because the firms become more efficient, the industries are better organized, or the allocation between industries is improved. In this paper we extend the literature on the measurement of industry efficiency (a decomposition in firm contributions and an organizational effect) to a third level, namely that of the economy. The huge task of interrelating the performance of an economy to industrial firm data is accomplished for Andalusia.     

Mail survey abroad with an alternative web survey

The large decline in cooperation in surveys experienced in the first decade of the twenty first century has placed representative surveys in a veritable quagmire, although numerous researchers have shown that the decline in the total nonresponse has been much higher in administered surveys (face-to-face and telephone) than in self-administered (mail and web surveys). The move from the “traditional” mail survey to the internet survey has brought important changes, but, at the same time, new challenges have arisen related to the lower coverage and the reduced visibility, the need for certain skills to fill out a questionnaire, changes in response rates, etc. This is a self-administered survey that informs the addressees by mail that they have been selected to participate in a research survey to which they can respond either by using the paper questionnaire (in the letter there is a prepaid envelope), by means of a web questionnaire (accessing a link and using a password), or by telephone (the respondent provided a contact time telephone number via a prepaid envelope or by calling an answering machine). The respondents themselves, therefore, choose the mode of response. An analysis of the responses achieved by each modality shows that the majority of the questionnaires were received by ordinary mail (83.6 %), 359 by internet (14.4 %), and 51 were answered by telephone (2.0 %).     

Stability of Risk Premia in the Italian Stock Market

In this work, we estimate the arbitrage pricing theory (APT) on the Italian Stock Market using the reduced-rank regression technique recently propossed by Bekker et al. (1996). Due to its computational simplicity, this technique allows extensive empirical analysis of the properties of the estimator employed. In this work, we carry out an initial exploration of the cross-sectional stability of the risk premia estimates in relation to the stocks' sample composition. We show that, by choosing an appropriately diversified sample, some acceptable degree of stability may be obtained. We also investigate, using the bootstrap method, the small sample properties of the estimator. (J.E.L.: G11, G12).
