PROGETTO DEL NUOVO STADIO DI CALCIO A GROSSETO

Il tema trattato dalla presente Tesi di Laurea riguarda il progetto del nuovo Stadio di calcio a Grosseto, la cui localizzazione in una zona periferica della città scaturisce dalle indicazioni contenute nel Piano Strutturale del Comune di Grosseto. In prima analisi è stato svolto lo studio tipologico edilizio degli stadi di calcio, approfondendo la raccolta su: cenni storici, conformazione architettonica e disposizione degli spazi; questa analisi ha contribuito ad affrontare con maggiore chiarezza lo studio progettuale. Lo studio è proseguito con la redazione del Documento preliminare all’avvio della progettazione (Dpp), introdotto dalla legge 109/94 e attuato dal DPR 554/99, con lo scopo di dare una corretta risposta alle esigenze del committente-utilizzatore. Il Dpp ha fornito le linee guida della successiva fase progettuale. In questa fase sono stati sviluppati tutti gli aspetti del progetto e curata la sistemazione esterna, intesa come parte integrante del progetto stesso (sistema di viabilità interna sia carrabile che pedonale, parcheggi, sistemazione del verde). Lo studio svolto ha riguardato anche gli aspetti legati all’accessibilità, in modo da garantire la corretta fruibilità anche da parte dei diversamente abili, e alla sicurezza durante le manifestazioni sportive al fine di creare condizioni ambientali ottimali per il regolare svolgimento dall’evento e la tutela dell’ordine e della sicurezza pubblica. La seconda parte della Tesi tratta il calcolo delle strutture ad un livello di progettazione preliminare e in modo più accurato quelle destinate alla copertura. Il progetto di dimensionamento di base della struttura è stato condotto nello spirito delle recenti norme prestazionali (D.M. 14 settembre 2005 “Norme tecniche per le costruzioni”), seguendo i criteri forniti dalla normativa europea (Eurocodice 3 e Eurocodice 4) per le verifiche sotto carichi statici della struttura

Investment decision and the spatial dimension : Evidence from firm level data

This paper proposes to investigate the effect of spillovers on location decision of firms. We develop an analysis merging the geographer toolbox with the standard econometric techniques. For a chosen sample of sectors, through the spatial data analysis, we test the existence of positive spatial autocorrelation for R&D investments that lead R&D expenditure to cluster. Moreover, we succeed in detecting how far the local environment may influence the firm decisions in R&D investments. Data confirm tha tthe proximity to other firms investing in R&D may produce positive externalities. Finally, the diversity vs. specialization debate is tackled.Local clustering;R@D investment;spatial autocorrelation

Coagglomeration and Spillovers

We study the coagglomeration of domestic plants and foreign multinationals and the impact of this on domestic plant productivity and employment using data for Irish manufacturing. Relying on a recently developed index we find that coagglomeration has been important for a number of industries. Our econometric analysis reveals that local foreign presence has indeed resulted in productivity spillovers to domestic plants, although only in those industries where there has been coagglomeration. Further evidence suggests that these spillovers have also resulted in more jobs.Coagglomeration, FDI, spillovers, Ireland

Polluting technologies and sustainable economic development

We study how the import of older and more polluting technologies alters the relationship between output and environmental quality in developing countries within a vintage capital framework. Our results show that old technologies prolong the period until which pollution may eventually decrease and cause this turning point to be reached at a higher level of pollution. An empirical analysis using export data of vintage technologies from the US and Europe to developing countries supports our theoretical findings.environmental quality, sustainable development, vintage technologies

Dry Times in Africa: Rainfall and Africa's Growth Performance

While there have been some references in the literature to the potential role of the general decline in rainfall in sub-Saharan African nations on their poor growth performance relative to other developing countries, this avenue remains empirically unexplored. In this paper we use a new cross-country panel climate data set in an economic growth framework to explore the issue. Our results show that rainfall has been a significant determinants of poor economic growth for Africa but not for other developing countries. Depending on the benchmark measure of potential rainfall, we estimate that the direct impact under the scenario of no decline in rainfall would have resulted in a reduction of between 13 and 36 per cent of today's gap in African GDP per capita relative to the rest of the developing world.Development, Africa, Climate

Deregulation shock in product market and unemployment

In a dynamic general equilibrium model with endogenous markups and labor market frictions, we investigate the effects of increased product market competition. Unlike most macroeconomic models of search, we endogenize the labor supply along the extensive margin. We show that beneficial effects in labor market outcomes require that the condition for saddle-path stability must be fulfilled whereas instability yields detrimental effects. Additionally, we find numerically that most of the decline in the unemployment rate can be attributed to the increase in the labor force, while the number of job seekers remains fairly unchanged. For a calibration capturing alternatively European and the U.S. labor markets, a deregulation episode, which lowers the markup by 3 percentage points, results in a fall in the unemployment rate by 0.1 and 0.05 percentage point, respectively, while the labor share is almost unaffected in the long-run.Imperfect competition; Endogenous markup; Search theory; Unemployment; Deregulation.

Climatic Change and Rural-Urban Migration: The Case of Sub-Saharan Africa

We investigate the role that climatic change has played in the pattern of urbanization in sub-Saharan countries compared to the rest of the developing world. To this end we assemble a cross-country panel data set that allows us to estimate the determinants of urbanization. The results of our econometric analysis suggest that climatic change, as proxied by rainfall, has acted to change urbanization in sub-Saharan Africa but not elsewhere in the developing world. Moreover, this link has become stronger since decolonization, which is likely due to the often simultaneous lifting of legislation prohibiting the free internal movement of native Africans.urbanization, climate change, rainfall, rural-urban migration, Africa

Trends in Rainfall and Economic Growth in Africa: A Neglected Cause of the Growth Tragedy

We examine the role of trends in rainfall in the poor growth performance of sub-Saharan African nations relative to other developing countries. To do so we use a new crosscountry panel climatic data set in an empirical economic growth framework. Our results show that rainfall has been a significant determinant of poor economic growth for Africa, but not for other developing countries. Depending on the benchmark measure of potential rainfall, we estimate that the direct impact under the scenario of no decline in rainfall would have resulted in a reduction of between around 15 and 40 per cent of todays gap in African GDP per capita relative to the rest of the developing world. --

The dynamics of Agglomeration: Evidence from Ireland and Portugal

This paper analyses and compares the dynamics of agglomeration in Portuguese and Irish manufacturing industries between 1985 and 1998 implementing Dumais, Ellison and Glaeser (2002)'s methodology. Using comparable and exhaustive micro-level data sets, we find that industries tend to be subject to strong geographical mobility despite little net aggregate changes in agglomeration in both countries. When the aggregate concentration changes are decomposed into portions attributable to the different stages of the plant life cycle, we discover that births consistently play a deagglomeration role, which continues at least into the early stages of the life cycle, whereas deaths have acted to reinforce agglomeration in both countries. Nevertheless, there are some differences across countries and industries.agglomeration, path dependence, plant's life cycle, Ireland, Portugal
