Economic conditions of islands and policies to rebalance territorial disparities

2022

The focus on island contexts stems from the fact that they present peculiarities related not only to the morphology of the territory but also to the economic and social system that characterises them. The territory of the European Union includes more than 3,000 islands in the Pacific, Atlantic and Indian Oceans, the Baltic Sea, the North Sea, the Mediterranean Basins and the Caribbean. The islands share similar social, geographical, economic, and environmental characteristics. Con- sidering only island regions, the European Union recognises more than 280 islands, identified as those territories surrounded by the sea, having an area of more than 1 km2, located at least one kilometre from the…

Cruise tourism effetcts in the EU Islands' economies

2007

The theme of ‘the island condition and the characteristics of the EU territories surrounded by the sea has already been treated in a number of studies and in some recent research projects which have highlighted disparities, structural disadvantages and the presence of an economy which relies excessively on tourism. The aim of this paper is to show the incoming tourism or daily visitors’ flows generated by cruises in the EU islands, and to present the tourist expenditure matrix and the composition of the main expenses. The results seem to show that local economies generated by cruise daily visitors if combined with local productions, could have a good level of economic impact.

A strategic approach for the discounted Shapley values

2014

The family of discounted Shapley values is analyzed for cooperative games in coalitional form. We consider the bargaining protocol of the alternating random proposer introduced in Hart and Mas-Colell (Econometrica 64:357–380, 1996). We demonstrate that the discounted Shapley values arise as the expected payoffs associated with the bargaining equilibria when a time discount factor is considered. In a second model, we replace the time cost with the probability that the game ends without agreements. This model also implements these values in transferable utility games, moreover, the model implements the \(\alpha \)-consistent values in the nontransferable utility setting.

Solidarity in games with a coalition structure

2010

Abstract A new axiomatic characterization of the two-step Shapley value Kamijo (2009) is presented based on a solidarity principle of the members of any union: when the game changes due to the addition or deletion of players outside the union, all members of the union will share the same gains/losses.

Gestión empresarial y dinámica laboral en España

2015

El objetivo del presente artículo es plantear una serie de reflexiones sobre la dinámica labo- ral reciente en la economía española bajo el enfoque analítico de la segmentación laboral. Desde esta perspectiva, la situación y problemas del mercado laboral se explican por un conjunto de factores relacionados con las prácticas de gestión empresarial y no tanto por la regulación que limita la competencia en el mercado o las modalidades contractuales. Nues- tra conclusión es que es necesario superar el marco analítico restringido del enfoque econó- mico convencional e introducir otras dimensiones, que van más allá del mercado, para una mejor compresión de los problemas laborales. En este sentido…

Ostacoli e determinanti dell’innovazione: un’analisi sulle imprese siciliane di successo

2010

Questo lavoro intende contribuire ad ampliare la precedente indagine Res sull’innovazione in Sicilia, soffermandosi in particolare ad analizzare i principali fattori di ostacolo alla realizzazione di innovazioni. In generale, le nostre elaborazioni mettono in evidenza l'esistenza di elevati livelli di percezione delle barriere territoriali esterne imposte dalle carenze del contesto (infrastrutture, pubblica amministrazione, servizi alle imprese etc.). Tuttavia, le nostre stime fanno emergere l’importanza delle barriere economiche e delle barriere relazionali nel determinare soprattutto le innovazioni di processo. Un altro risultato della ricerca sottolinea l’elevato grado di interdipendenza…

Global Divergence in Growth Regressions

2013

This paper extends the standard growth regression model by adding an assumption that a country follows the global technology frontier either fully or partially. This additional assumption changes significantly the growth regression model and its results in three main ways. First, it shows that although a country converges to its long-run growth path, this path can diverge from the countries at the global frontier. We measure the degree of divergence for each country and find that most indeed diverge from the frontier. Second, we estimate growth dynamics without controlling for additional variables. Third, our new method enables us to disentangle the effects of the explanatory variables on t…

Transitions out of unemployment: The role of social networks' topology and firms' recruitment strategies

2011

In this paper we study the effects of job contact networks on out-of-unemployment transitions. We find that social connections produce sizable increases in upward mobility from unemployment and, caeteris paribus, symmetric network topologies perform better than asymmetric ones. Furthermore, in scale-free networks the probability of transitions out of unemployment increases in the exponent of the power-law degree distribution, but its value is much lower than the one attainable in Poisson random networks. In addition, and most interestingly, these results strongly depends on the different hypotheses on the firms' recruitment strategy.

Structural Dynamics of Interfirm Knowledge Networks

2016

In this chapter, we investigate the drivers of interfirm network structural dynamics and their influence on knowledge creation and diffusion processes that occur in such networks over time. Interfirm knowledge networks are complex webs of linkages connecting a variety of idiosyncratic firms within and across industries. Aimed to contribute to answer the recent calls for a more dynamic and multilevel view to understand network structures and processes, we leverage the complex network research to formulate a multilevel theoretical framework that clarifies the structural dynamics and knowledge creation and diffusion potential of interfirm networks.

Assessing Climate Change Adaptation and Risk Management Programmes: Stakeholder Participation Process and Policy Implications for Transport, Energy a…

2022

Climate change is a critical sustainability challenge for islands and their main economic sectors. Rising sea levels, extreme temperatures, and drier conditions are the impacts with the most significant potential to amplify the economic damage on islands. However, their isolation and natural conditions bring about some leeway to respond to climate impacts on their terms. This paper aims to provide a local-level analysis and ranking of alternative adaptation pathways in an island context through the stakeholders’ lens. This study reviews the latest advancements in adaptation science and proposes a catalogue of adaptation and risk management options that feed a participatory assessment …
