Educational disparities across regions: A multilevel analysis for Italy and Spain

In this paper, a multilevel analysis is applied to the OECD-PISA2006 data with the aim to compare factors affecting students’ achievement across Italy and Spain. The findings show that both countries are affected by strong internal regional heterogeneity, where some regions have achievement scores well above the OECD mean and other are placed among the worst performers in the OECD area. Although regional governments are more autonomous about educational policy-making in Spain, regional indicators exert a higher influence on educational results in Italy where educational system is strictly regulated by the national government.     

Using simulation to manage project supply chain in the offshore oil and gas industry

This paper is aimed at comparing simulation against spreadsheets as decision support tools to properly manage project supply chain in the offshore oil and gas industry. The paper presents a case study related to the problem of sizing a chain for pipeline laying from an offshore field in the Barents sea to the Russian coast. Results obtained through a spreadsheet developed by an oil and gas company have been compared to the ones gathered from an ad hoc simulation model. A simulation model with no stochastic variable has been introduced: results are quite similar to the ones of the spreadsheet, which allowed to validate the simulation model. However, the spreadsheet cannot take into account the continuous move of the pipe-lay vessel while laying the pipes and it does not consider stochastic variables whose effect in real life is not negligible. Both weaknesses above are discussed.     

The Determinants of Contract Length in Temporary Help Employment

Abstract. This paper investigates the determinants of labor contract duration in the case of temporary help employment. A simple theoretical model is developed, in order to depict the choice of contract length made by a firm that recruits temporary agency workers to deal with activity peaks. Assuming that the hiring of a new worker is associated with selection and training costs, longer contracts have an option value in face of a greater persistence of positive shocks. The model has two testable implications. First, the degree of serial correlation in market demand positively affects contract length. Second, the shortage of alternative employment opportunities negatively affects contract length. Using data on Italian temporary agency workers, both implications are confirmed by the econometric analysis.     

UNBUNDLING THE INCUMBENT: EVIDENCE FROM UK BROADBAND

We consider the impact of a regulatory process forcing an incumbent telecom operator to make its local broadband network available to other companies (local loop unbundling, or LLU). Entrants are then able to upgrade their individual lines and offer Internet services directly to customers. Employing a very detailed data set covering the whole of the United Kingdom, we find that, over the course of time, many entrants have begun to take advantage of unbundling. LLU entry only had a positive effect on broadband penetration in the early years, and no longer in the recent years as the market reached maturity. In contrast, LLU entry continues to have a positive impact on the quality of the service provided, as entrants differentiate their products upwards compared to the incumbent. We also assess the impact of competition from an alternative form of technology (cable) which is not subject to regulation, and what we discover is that inter‐platform competition has a positive impact on both penetration and quality.     

Accountability as a Managerial Tool in Non-Profit Organizations: Evidence from Italian CSVs

The long-term performance of NPOs is based on their ability to link and maximize social value as defined in their mission. This involves legitimacy obtained from stakeholders influenced by and influencing NPO activities, and their operational capacity or economic efficiency. Thus, NPOs have to utilize multiple level accountability systems which should be compatible with their multiple objectives and stakeholders’ claims. The accountability system of an NPO should focus on its operational capacity, because in order to maximize its efficiency, an NPO has to measure its resource use, cost structure, and financial structure. Legitimacy obtained from stakeholders is also integral. If an organization is considered a social contract between multiple stakeholders, it has to consider the social economic effects of its activities and it has the duty to account for them. However, since the mission of an NPO is to create and distribute social value to a certain specific group, its social value creation has the most important role and an NPO should measure the social value it has created. This article analyzes the accountability system of a specific type of Italian NPO called Centri di Servizio per il Volontariato (CSVs)—namely centers which provide services for voluntary associations. The aim of the research is to verify if the accountability system adopted by CSVs satisfies their need for multiple level information (operational, legitimacy, and social value) and accomplishes their stakeholder claims, and to determine its impact on the definition and implementation of their strategy and on their long-term performance. The research was carried out using the action research model, and the findings are based on the analysis of a sample of 64 CSVs situated throughout Italy.     

Identifying Demand and Supply of Part‐time Jobs Using Personnel Data. An Application to Italy

The percentage of part‐time workers in Italy is very low compared with most European countries. In this paper we try to contribute to an explanation. We use data on the employees of a large Italian company operating in the service sector, and apply a particular econometric framework that allows identification of potential demand and supply. We find that demand and supply are potentially very large on average, but they are difficult to match at the individual worker/job level. The firm might observe a relevant employee’s characteristics that are positively correlated with the employee’s propensity to a part‐time job but are negatively correlated with the profitability of that employee on that job. The firm might also use the revealed willingness to switch to a part‐time job as a sign that the employee is likely to be unprofitable for the company.     

Search and Recombination Process to Innovate: A Review of the Empirical Evidence and a Research Agenda

The view of innovation as a process of searching and recombining existing knowledge elements has been adopted in several industries. The innovation management literature has recognized the fundamental role that search and recombination play in innovation development. However, the relevant research has provided complex, fragmented and mixed results. The authors aim to identify areas of convergence and provide directions for future research by collecting empirical evidence regarding how firms conduct the search and recombination process. They conducted a systematic literature review of 87 empirical articles in the innovation management field. The review reveals differences among the solutions adopted both within and across organizational boundaries. Specifically, it shows that the variety and diversity of knowledge elements are critical in creating breakthrough innovations. Therefore, this paper discusses how to provide access to a variety of knowledge elements. It also highlights other fundamental questions calling for further investigation, such as how scientific knowledge elements are successfully recombined and how recombination and search dynamics occur in small and medium‐sized firms. The review concludes by summarizing the current state of affairs and suggests promising directions for future investigation.     

Who is watching? The market for prostitution services

This paper presents an economic model of prostitution that differs from the existing literature in that it makes no restrictive assumptions regarding the gender, pay, and nature of forgone earning opportunities of prostitutes and clients, and applies the same behavioural hypotheses to both. Our model gives a central role of stigma and reputation effects to both clients and prostitutes. We discuss demand, supply, and equilibrium results, indicating the possible effects of different policies on the industry and its different markets.     

The relevance of educational poverty in Europe: Determinants and remedies

This paper explores the degree of educational poverty in European countries using data from OECD Programme for International Student Assessment (PISA). This research adopts the class of additive multidimensional poverty measures proposed by Alkire & Foster (2011) and investigates the degree of educational poverty in terms of incidence, breadth, depth and severity. Also, we analyse the impact of students’ characteristics and school-level factors on the probability of being educational poor in various learning dimensions. The findings reveal that between 2006 and 2015 the incidence of educational poverty became more relevant in many European countries, while most of them experienced a reduction of poverty depth and severity. Therefore, several policy scenarios are simulated in order to highlight the school factors that can be activate to alleviate the risk of educational poverty in the European countries that experienced the highest incidence of educational poor student.
