Politiche Antitrust e crescita economica / Antitrust policy and economic growth

Volgarino, Antonella <1983> 14 June 2012 (has links)
Negli ultimi anni le istituzioni e la regolamentazione hanno svolto un ruolo sempre più importante nell’analisi della crescita economica. Tuttavia, non è facile interpretare le istituzioni e gli effetti dei regolamenti sulla crescita attraverso indicatori che tendono a “misurare” le istituzioni. Lo scopo di questa ricerca è analizzare la relazione di lungo periodo tra la crescita economica e la regolamentazione e il ruolo della regolamentazione antitrust sulla crescita economica. La stima econometrica dei modelli di crescita con la concorrenza e gli indicatori di potere di mercato si base su un dataset appositamente costruito che copre 211 Paesi, su un arco temporale massimo di 50 anni (da 1960 a 2009). In particolare, cerchiamo di identificare un quadro analitico volto a integrare l’analisi istituzionale ed economica al fine di valutare il ruolo della regolamentazione e, più in generale, il ruolo delle istituzioni nella crescita economica. Dopo una revisione della letteratura teorica ed empirica sulla crescita e le istituzioni, vi presentiamo l’analisi dell'impatto normativo (RIA) in materia di concorrenza, e analizziamo le principali misure di regolamentazione, la governance e le misure antitrust. Per rispondere alla nostra domanda di ricerca si stimano modelli di crescita prendendo in considerazione tre diverse misure di regolamentazione: la Regulation Impact (RI), la Governance (GOV), e la libertà economica (LIB). Nel modello a effetti fissi, RI, gli effetti della legislazione antitrust sulla crescita economica sono significativi e positivi, e gli effetti di durata antitrust sono significativi, ma negativi. Nel pannel dinamico, GOV, gli effetti dell’indicatore di governance sulla crescita sono notevoli, ma negativo. Nel pannel dinamico, LIB, gli effetti della LIB sono significativi e negativi. / During last years institutions and regulations have played an increasingly and important role in the growth economic analysis. However, it is not easy to interpret the institutions and regulations effects on growth using indicators which tend to “measure” institutions. The purpose of this research is analyse the long-run relationship between economic growth and regulation, and the role of antitrust regulation on economic growth. Our econometric estimation of growth models with competition and market power indicators based on an expressly conceived dataset including 211 countries, over a maximum period range of 50 years (from 1960 to 2009). In particular, we try to identify an analytical framework aiming to complement the institutional and economic analysis in order to assess the regulation role and more generally, the role of institutions in economic growth. After a theoretical and empirical literature review on growth and institutions, we present the Regulatory Impact Analysis (RIA) on competition, and we analyse the main regulation, governance and antitrust measures. To answer our research question we estimate several growth models considering three regulatory measures: Regulation Impact (RI), Governance (GOV), and Economic Freedom (LIB). In the RI fixed effect model, the effects of antitrust legislation on economic growth are significant and positive, and the effects of antitrust duration are significant but negative. In the GOV dynamic panel, the effects of governance index on growth are significant but negative. In the LIB dynamic panel the effects of LIB are significant and negative.

Analyzing convergence of Agricultural and Rural Areas in the Enlarged EU: The case of Hungary

Monasterolo, Irene <1982> 31 May 2012 (has links)
The fall of the Berlin Wall opened the way for a reform path – the transition process – which accompanied ten former Socialist countries in Central and South Eastern Europe to knock at the EU doors. By the way, at the time of the EU membership several economic and structural weaknesses remained. A tendency towards convergence between the new Member States (NMS) and the EU average income level emerged, together with a spread of inequality at the sub-regional level, mainly driven by the backwardness of the agricultural and rural areas. Several progresses were made in evaluating the policies for rural areas, but a shared definition of rurality is still missing. Numerous indicators were calculated for assessing the effectiveness of the Common Agricultural Policy and Rural Development Policy. Previous analysis on the Central and Eastern European countries found that the characteristics of the most backward areas were insufficiently addressed by the policies enacted; the low data availability and accountability at a sub-regional level, and the deficiencies in institutional planning and implementation represented an obstacle for targeting policies and payments. The next pages aim at providing a basis for understanding the connections between the peculiarities of the transition process, the current development performance of NMS and the EU role, with particular attention to the agricultural and rural areas. Applying a mixed methodological approach (multivariate statistics, non-parametric methods, spatial econometrics), this study contributes to the identification of rural areas and to the analysis of the changes occurred during the EU membership in Hungary, assessing the effect of CAP introduction and its contribution to the convergence of the Hungarian agricultural and rural. The author believes that more targeted – and therefore efficient – policies for agricultural and rural areas require a deeper knowledge of their structural and dynamic characteristics.

Le produzioni agroalimentari di qualità nelle aziende agricole dell’Emilia-Romagna: un’analisi comparativa con le aziende agricole convenzionali / The farms with quality foods production in Emilia-Romagna: a comparative analysis with conventional farms

Spinelli, Lucilla <1979> 31 May 2012 (has links)
Il tema dei prodotti agroalimentari di qualità ha ormai assunto un ruolo rilevante all’interno del dibattito riguardante l’agricoltura e l’economia agroalimentare, ponendosi al centro dell’interesse delle politiche europee (PAC post 2013, Pacchetto Qualità). La crescente attenzione verso le produzioni con marchio Dop\Igp mette però in luce la sostanziale carenza di informazioni dettagliate relativamente alle aziende che operano in questo comparto. Da questo punto di vista il VI° Censimento generale dell’agricoltura costituisce una preziosa fonte di informazioni statistiche. L’obiettivo di questo lavoro è quello di utilizzare i dati, ancora provvisori, del censimento per analizzare la struttura delle aziende con produzioni di qualità, ponendola in confronto con quella delle aziende convenzionali. Inoltre è stata fatta una classificazione delle aziende con prodotti Dop\Igp, in base alla rilevanza di queste produzioni sul reddito lordo aziendale. Le aziende sono quindi state classificate come “Specializzate” e “Miste”, con un’ulteriore distinzione di queste ultime tra quelle “Prevalentemente Dop\Igp” e quelle “Prevalentemente non Dop\Igp”. Tale ripartizione ha consentito una definizione dettagliata degli orientamenti produttivi delle aziende analizzate. / Recently, within the debate concerning agriculture and its economy, the problem of food quality becomes much more central for the European politics (PAC post 2013, Quality package 2010). This increasing attention on Pdo\Pgi productions, is truly underlining the lack in information about farms and factories actually working in this field. To solve this problem, the VI° Agricultural Census could be considered as a great source of statistical data. Aim of this study was to use this dataset to analyze those farms which are, so far, producing quality foods, comparing them to the more conventional ones. Moreover, a chart based on the relevance of Pdo\Pgi production on the whole farms net gain was created. Farms were then clustered in “specialized” and “mixed”; the last were again separated in two more groups: “mainly Pdo\Pgi” and “mainly not Pdo\Pgi”. This kind of partition allowed a more detailed definition of the productive tendency in the analyzed farms.

A farm-level programming model to compare the atmospheric impact of conventional and organic farming

Signorotti, Claudio <1972> 04 July 2013 (has links)
A model is developed to represent the activity of a farm using the method of linear programming. Two are the main components of the model, the balance of soil fertility and the livestock nutrition. According to the first, the farm is supposed to have a total requirement of nitrogen, which is to be accomplished either through internal sources (manure) or through external sources (fertilisers). The second component describes the animal husbandry as having a nutritional requirement which must be satisfied through the internal production of arable crops or the acquisition of feed from the market. The farmer is supposed to maximise total net income from the agricultural and the zoo-technical activities by choosing one rotation among those available for climate and acclivity. The perspective of the analysis is one of a short period: the structure of the farm is supposed to be fixed without possibility to change the allocation of permanent crops and the amount of animal husbandry. The model is integrated with an environmental module that describes the role of the farm within the carbon-nitrogen cycle. On the one hand the farm allows storing carbon through the photosynthesis of the plants and the accumulation of carbon in the soil; on the other some activities of the farm emit greenhouse gases into the atmosphere. The model is tested for some representative farms of the Emilia-Romagna region, showing to be capable to give different results for conventional and organic farming and providing first results concerning the different atmospheric impact. Relevant data about the representative farms and the feasible rotations are extracted from the FADN database, with an integration of the coefficients from the literature.

Il cambiamento della ruralità nell'Unione Europea. Tipologie, evoluzione e risposte alle politiche / EU rural areas under major transformations

Pagliacci, Francesco <1983> 04 July 2013 (has links)
Obiettivo del lavoro è migliorare la lettura della ruralità europea. A fronte delle profonde trasformazioni avvenute, oggi non è più possibile analizzare i territori rurali adottando un mero approccio dicotomico che semplicemente li distingua dalle città. Al contrario, il lavoro integra l’analisi degli aspetti socio-economici con quella degli elementi territoriali, esaltando le principali dimensioni che caratterizzano le tante tipologie di ruralità oggi presenti in Europa. Muovendo dal dibattito sulla classificazione delle aree rurali, si propone dapprima un indicatore sintetico di ruralità che, adottando la logica fuzzy, considera congiuntamente aspetti demografici (densità), settoriali (rilevanza dell’attività agricola), territoriali e geografici (accessibilità e uso del suolo). Tale tecnica permette di ricostruire un continuum di gradi di ruralità, distinguendo così, all’interno dell’Unione Europea (circa 1.300 osservazioni), le aree più centrali da quelle progressivamente più rurali e periferiche. Successivamente, attraverso un’analisi cluster vengono individuate tipologie di aree omogenee in termini di struttura economica, paesaggio, diversificazione dell’attività agricola. Tali cluster risentono anche della distribuzione geografica delle aree stesse: vengono infatti distinti gruppi di regioni centrali da gruppi di regioni più periferiche. Tale analisi evidenzia soprattutto come il binomio ruralità-arretratezza risulti ormai superato: alcune aree rurali, infatti, hanno tratto vantaggio dalle trasformazioni che hanno interessato l’Unione Europea negli ultimi decenni (diffusione dell’ICT o sviluppo della manifattura). L’ultima parte del lavoro offre strumenti di analisi a supporto dell’azione politica comunitaria, analizzando la diversa capacità delle regioni europee di rispondere alle sfide lanciate dalla Strategia Europa 2020. Un’analisi in componenti principali sintetizza le principali dimensioni di tale performance regionale: i risultati sono poi riletti alla luce delle caratteristiche strutturali dei territori europei. Infine, una più diretta analisi spaziale dei dati permette di evidenziare come la geografia influenzi ancora profondamente la capacità dei territori di rispondere alle nuove sfide del decennio. / This work is aimed at providing a better analysis about EU rural areas. Lately, those regions have widely changed: thus, a dichotomous approach, simply distinguishing rural areas from cities, cannot take into account the increasing complexity affecting EU regions. Actually, the research is based on a multidimensional approach, by including within the analysis both socio-economic and geographical characteristics. Moving from the wide debate on the classification of rural areas, a comprehensive rurality index is computed by applying fuzzy logic to the whole set of EU regions (about 1,300 observations). This continuous index highlights the different extents of rurality, according to demographic aspects (e.g., density), economic features (e.g., relevance of the agricultural sector) and geographical characteristics (e.g., accessibility and remoteness). Then, a cluster analysis is applied. According to the regional economic structure, the diversification of the agricultural activities and the land use characteristics, homogeneous clusters are identified. They are also geographically defined. Actually, some groups of more central rural regions have taken advantage from the major transformations having affected the EU (e.g., the improvement in the ICT, the diffusion of manufacturing activities across rural areas,…). Thus, the link between rurality and underdevelopment can be considered almost outdated. Lastly, some tools for the analysis of the EU political actions are provided. The regional performance in achieving Europe 2020 Strategy targets is analysed. First, this performance at the regional level is summed up by adopting a principal component analysis. Then, the main results are linked with the comprehensive rurality index and the main evidences from the cluster analysis. Moreover, this performance is also analysed according to an exploratory spatial data analysis approach. Actually, geography still affects the way each region faces the new challenges for the next decade.

Sviluppo economico e qualità istituzionale: il ruolo di disuguaglianza e corruzione / Economic development and institutional quality: the role of inequality and corruption

Reverberi, Pierre Maurice <1983> 04 July 2013 (has links)
Nell'ambito delle teorie dello sviluppo, un filone di studi, originato dai lavori di North (1973) e consolidatosi negli ultimi anni, individua nelle istituzioni, definite come le regole del gioco o i vincoli disegnati dagli uomini per disciplinare i loro rapporti, i fattori fondamentali dello sviluppo economico. Le istituzioni, nel modello elaborato da Acemoglu, Johnson e Robinson (2004), sono il frutto di interazioni dinamiche tra potere politico de jure, determinato dalle istituzioni politiche, e potere politico de facto, determinato dalla distribuzione delle risorse economiche. Sulla base di questa prospettiva teorica, questa tesi propone uno studio di carattere quantitativo sulla qualità istituzionale, la traduzione operativa del concetto di istituzioni, composta dalle tre fondamentali dimensioni di democrazia, efficienza ed efficacia del governo e assenza di corruzione. La prima parte, che analizza sistematicamente pro e contro di ciascuna tipologia di indicatori, è dedicata alla revisione delle misure quantitative di qualità istituzionale, e individua nei Worldwide Governance Indicators la misura più solida e consistente. Questi indici sono quindi utilizzati nella seconda parte, dove si propone un'analisi empirica sulle determinanti della qualità istituzionale. Le stime del modello di regressione cross-country evidenziano che la qualità istituzionale è influenzata da alcuni fattori prevalentemente esogeni come la geografia, la disponibilità di risorse naturali e altre caratteristiche storiche e culturali, insieme ad altri fattori di carattere più endogeno. In quest'ultima categoria, i risultati evidenziano un effetto positivo del livello di sviluppo economico, mentre la disuguaglianza economica mostra un impatto negativo su ciascuna delle tre dimensioni di qualità istituzionale, in particolare sulla corruzione. Questi risultati supportano la prospettiva teorica e suggeriscono che azioni di policy orientate alla riduzione delle disparità sono capaci di generare sviluppo rafforzando la democrazia, migliorando l'efficienza complessiva del sistema economico e riducendo i livelli di corruzione. / Amongst development theories, following the work of D. North (1973), a branch of studies has recently developed which sees institutions, defined as the rules of the game or humanly devised constraints that shape human interaction, as the fundamental cause of long-run growth. The model constructed by Acemoglu, Johnson and Robinson (2004) emphasizes the interaction between de jure political power, influenced by political institutions, and de facto political power, shaped by distribution of resources, in the evolution of institutional paths. Based on this theoretical framework, this thesis adopts a quantitative perspective to investigate institutional quality, which is composed by three main dimensions: democracy, government efficiency and effectiveness and corruption. A survey of available measures of institutional quality is conducted in order to evaluate pro and cons of each kind of indicators. The analysis finds the World Bank's Worldwide Governance Indicators as the most reliable measures of institutional quality, both in terms of internal and external consistency. These indexes are then used for an empirical analysis over the determinants of institutional quality. The estimates of the cross-country regression model show that institutional quality is affected by some exogenous factors, like geography, natural resources endowments and other historic and cultural traits, and more endogenous factors. Amongst the latter, economic development exerts a positive effect on institutional quality, while a negative association, particularly on the corruption side, is shown by economic inequality. Results confirm our hypothesis and suggest that policies aiming at reducing inequality can foster development by strengthening democracy, by improving the overall efficiency of the economic system and by reducing corruption levels.

Alla ricerca della sostenibilità: lo sviluppo dell'agricoltura dall'Unità d'Italia alla Green Economy / Looking for sustainability: Italian Agro-food sector development, from the Unification of the country to Green Economy.

Parodi, Gianluca <1982> 04 July 2013 (has links)
L’elaborato finale presentato per la tesi di Dottorato analizza e riconduce a unitarietà, per quanto possibile, alcune delle attività di ricerca da me svolte durante questi tre anni, il cui filo conduttore è l'impatto ambientale delle attività umane e la promozione dello sviluppo sostenibile. Il mio filone di ricerca è stato improntato, dal punto di vista di politica economica, sull'analisi storica dello sviluppo del settore agricolo dall'Unità d'Italia ai giorni nostri e dei cambiamenti avvenuti in contemporanea nel contesto socio-economico e territoriale nazionale, facendo particolare riferimento alle tematiche legate ai consumi e alla dipendenza energetica ed all'impatto ambientale. Parte della mia ricerca è stata, infatti, incentrata sull'analisi dello sviluppo della Green Economy, in particolare per quanto riguarda il settore agroalimentare e la produzione di fonti di energia rinnovabile. Enfasi viene posta sia sulle politiche implementate a livello comunitario e nazionale, sia sul cambiamento dei consumi, in particolare per quanto riguarda gli acquisti di prodotti biologici. La Green Economy è vista come fattore di sviluppo e opportunità per uscire dall'attuale contesto di crisi economico-finanziaria. Crisi, che è strutturale e di carattere duraturo, affiancata da una crescente problematica ambientale dovuta all'attuale modello produttivo, fortemente dipendente dai combustibili fossili. Difatti la necessità di cambiare paradigma produttivo promuovendo la sostenibilità è visto anche in ottica di mitigazione del cambiamento climatico e dei suoi impatti socio-economici particolare dal punto di vista dei disastri ambientali. Questo punto è analizzato anche in termini di sicurezza internazionale e di emergenza umanitaria, con riferimento al possibile utilizzo da parte delle organizzazioni di intervento nei contesti di emergenza di tecnologie alimentate da energia rinnovabile. Dando così una risposta Green ad una problematica esacerbata dall'impatto dello sviluppo delle attività umane. / My PhD thesis is the final output of my research activities carried out during these three years. The main objectives that I have analyzed, and tried to merge as much as possible here, is the promotion of sustainable development and the environmental impact of human activities. My research line has been characterized on the analysis of the historical development of the Italian agricultural sector and the changes simultaneously occurring in the social and economic structure. Particular focus has been put on energy consumption and dependence from importation, territorial aspects and environmental impacts. Part of my analysis focused on the recent development of the Green Economy, in particular concerning the agro-food sector and the production of renewable energy sources. Emphasis is placed both on policies for promoting sustainability implemented at EU and national level and on consumption's changes in particular with regard to organic products. Green Economy is seen as a factor of development and as an opportunity to overcome the current context of economic and financial crisis. Crisis that is lasting and structural, moreover it has been worsened by growing environmental problems given by human activities and actual production model that is strongly dependent from fossil fuels. In fact, the necessity of changing production paradigm and promoting sustainability is also seen from a perspective of mitigating social and economic impact of climate change, particularly from environmental disasters point of view and related to humanitarian crisis. This point has been also analyzed in terms of international security and humanitarian emergency, with reference to possible application of green technologies by the side of emergency organizations during disaster relief and therefore giving a further green answer to such problem linked to global warming exacerbated by human activities.

Regulating State Aid: Inter-jurisdictional competition, public choice, and corporate governance

Hanke, Philip Cosmo <1983> 24 June 2014 (has links)
Depending on the regulatory regime they are subject to, governments may or may not be allowed to hand out state aid to private firms. The economic justification for state aid can address several issues present in the competition for capital and the competition for transfers from the state. First, there are principal-agent problems involved at several stages. Self-interested politicians might enter state aid deals that are the result of extensive rent-seeking activities of organized interest groups. Thus the institutional design of political systems will have an effect on the propensity of a jurisdiction to award state aid. Secondly, fierce competition for firm locations can lead to over-spending. This effect is stronger if the politicians do not take into account the entirety of the costs created by their participation in the firm location race. Thirdly, state aid deals can be incomplete and not in the interest of the citizens. This applies if there are no sanctions if firms do not meet their obligations from receiving aid, such as creating a certain number of jobs or not relocating again for a certain amount of time. The separation of ownership and control in modern corporations leads to principal-agent problems on the side of the aid recipient as well. Managers might receive personal benefits from subsidies, the use of which is sometimes less monitored than private finance. This can eventually be to the detriment of the shareholders. Overall, it can be concluded that state aid control should also serve the purpose of regulating the contracting between governments and firms. An extended mandate for supervision by the European Commission could include requirements to disincentive the misuse of state aid. The Commission should also focus on the corporate governance regime in place in the jurisdiction that awards the aid as well as in the recipient firm.

Spatial Disparity and Dynamic Trajectory of Convergence in China: Construction and Application of a Composite Index of Regional Development

Bin, Peng <1984> 14 May 2014 (has links)
China is a large country characterized by remarkable growth and distinct regional diversity. Spatial disparity has always been a hot issue since China has been struggling to follow a balanced growth path but still confronting with unprecedented pressures and challenges. To better understand the inequality level benchmarking spatial distributions of Chinese provinces and municipalities and estimate dynamic trajectory of sustainable development in China, I constructed the Composite Index of Regional Development (CIRD) with five sub pillars/dimensions involving Macroeconomic Index (MEI), Science and Innovation Index (SCI), Environmental Sustainability Index (ESI), Human Capital Index (HCI) and Public Facilities Index (PFI), endeavoring to cover various fields of regional socioeconomic development. Ranking reports on the five sub dimensions and aggregated CIRD were provided in order to better measure the developmental degrees of 31 or 30 Chinese provinces and municipalities over 13 years from 1998 to 2010 as the time interval of three “Five-year Plans”. Further empirical applications of this CIRD focused on clustering and convergence estimation, attempting to fill up the gap in quantifying the developmental levels of regional comprehensive socioeconomics and estimating the dynamic convergence trajectory of regional sustainable development in a long run. Four clusters were benchmarked geographically-oriented in the map on the basis of cluster analysis, and club-convergence was observed in the Chinese provinces and municipalities based on stochastic kernel density estimation.
