The role of collective action in the provision of agri-environmental public goods: theoretical development through case studies in Italy

The thesis aims at analysing the role of collective action as a viable alternative to the traditional forms of intervention in agriculture in order to encourage the provision of agri-environmental public goods. Which are the main benefits of collective action, in terms of effectiveness and efficiency, compared to traditional market or public intervention policies? What are the drivers that encourage farmers to participate into collective action? To what extent it is possible to incorporate collective aspects into policies aimed at providing agri-environmental public goods? With the objective of addressing these research questions, the thesis is articulated in two levels: a theoretical analysis on the role of collective action in the provision of public goods and a specific investigation of two local initiative,s were an approach collective management of agro-environmental resources was successfully implemented. The first case study concerns a project named “Custodians of the Territory”, developed by the local agency in Tuscany “Comunità Montana Media Valle del Serchio”, which settled for an agreement with local farmers for a collective provision of environmental services related to the hydro-geological management of the district. The second case study is related to the territorial agri-environmental agreement experimented in Valdaso (Marche), where local farmers have adopted integrated pest management practices collectively with the aim of reducing the environmental impact of their farming practices. The analysis of these initiatives, carried out through participatory methods (Rapid Rural Appraisal), allowed developing a theoretical discussion on the role of innovative tools (such as co-production and co-management) in the provision of agri-environmental public goods. The case studies also provided some recommendations on the government intervention and policies needed to promote successful collective action for the provision of agri-environmental public goods.

Essays on the political economy of European integration

Recently, a rising interest in political and economic integration/disintegration issues has been developed in the political economy field. This growing strand of literature partly draws on traditional issues of fiscal federalism and optimum public good provision and focuses on a trade-off between the benefits of centralization, arising from economies of scale or externalities, and the costs of harmonizing policies as a consequence of the increased heterogeneity of individual preferences in an international union or in a country composed of at least two regions. This thesis stems from this strand of literature and aims to shed some light on two highly relevant aspects of the political economy of European integration. The first concerns the role of public opinion in the integration process; more precisely, how economic benefits and costs of integration shape citizens' support for European Union (EU) membership. The second is the allocation of policy competences among different levels of government: European, national and regional. Chapter 1 introduces the topics developed in this thesis by reviewing the main recent theoretical developments in the political economy analysis of integration processes. It is structured as follows. First, it briefly surveys a few relevant articles on economic theories of integration and disintegration processes (Alesina and Spolaore 1997, Bolton and Roland 1997, Alesina et al. 2000, Casella and Feinstein 2002) and discusses their relevance for the study of the impact of economic benefits and costs on public opinion attitude towards the EU. Subsequently, it explores the links existing between such political economy literature and theories of fiscal federalism, especially with regard to normative considerations concerning the optimal allocation of competences in a union. Chapter 2 firstly proposes a model of citizens’ support for membership of international unions, with explicit reference to the EU; subsequently it tests the model on a panel of EU countries. What are the factors that influence public opinion support for the European Union (EU)? In international relations theory, the idea that citizens' support for the EU depends on material benefits deriving from integration, i.e. whether European integration makes individuals economically better off (utilitarian support), has been common since the 1970s, but has never been the subject of a formal treatment (Hix 2005). A small number of studies in the 1990s have investigated econometrically the link between national economic performance and mass support for European integration (Eichenberg and Dalton 1993; Anderson and Kalthenthaler 1996), but only making informal assumptions. The main aim of Chapter 2 is thus to propose and test our model with a view to providing a more complete and theoretically grounded picture of public support for the EU. Following theories of utilitarian support, we assume that citizens are in favour of membership if they receive economic benefits from it. To develop this idea, we propose a simple political economic model drawing on the recent economic literature on integration and disintegration processes. The basic element is the existence of a trade-off between the benefits of centralisation and the costs of harmonising policies in presence of heterogeneous preferences among countries. The approach we follow is that of the recent literature on the political economy of international unions and the unification or break-up of nations (Bolton and Roland 1997, Alesina and Wacziarg 1999, Alesina et al. 2001, 2005a, to mention only the relevant). The general perspective is that unification provides returns to scale in the provision of public goods, but reduces each member state’s ability to determine its most favoured bundle of public goods. In the simple model presented in Chapter 2, support for membership of the union is increasing in the union’s average income and in the loss of efficiency stemming from being outside the union, and decreasing in a country’s average income, while increasing heterogeneity of preferences among countries points to a reduced scope of the union. Afterwards we empirically test the model with data on the EU; more precisely, we perform an econometric analysis employing a panel of member countries over time. The second part of Chapter 2 thus tries to answer the following question: does public opinion support for the EU really depend on economic factors? The findings are broadly consistent with our theoretical expectations: the conditions of the national economy, differences in income among member states and heterogeneity of preferences shape citizens’ attitude towards their country’s membership of the EU. Consequently, this analysis offers some interesting policy implications for the present debate about ratification of the European Constitution and, more generally, about how the EU could act in order to gain more support from the European public. Citizens in many member states are called to express their opinion in national referenda, which may well end up in rejection of the Constitution, as recently happened in France and the Netherlands, triggering a European-wide political crisis. These events show that nowadays understanding public attitude towards the EU is not only of academic interest, but has a strong relevance for policy-making too. Chapter 3 empirically investigates the link between European integration and regional autonomy in Italy. Over the last few decades, the double tendency towards supranationalism and regional autonomy, which has characterised some European States, has taken a very interesting form in this country, because Italy, besides being one of the founding members of the EU, also implemented a process of decentralisation during the 1970s, further strengthened by a constitutional reform in 2001. Moreover, the issue of the allocation of competences among the EU, the Member States and the regions is now especially topical. The process leading to the drafting of European Constitution (even if then it has not come into force) has attracted much attention from a constitutional political economy perspective both on a normative and positive point of view (Breuss and Eller 2004, Mueller 2005). The Italian parliament has recently passed a new thorough constitutional reform, still to be approved by citizens in a referendum, which includes, among other things, the so called “devolution”, i.e. granting the regions exclusive competence in public health care, education and local police. Following and extending the methodology proposed in a recent influential article by Alesina et al. (2005b), which only concentrated on the EU activity (treaties, legislation, and European Court of Justice’s rulings), we develop a set of quantitative indicators measuring the intensity of the legislative activity of the Italian State, the EU and the Italian regions from 1973 to 2005 in a large number of policy categories. By doing so, we seek to answer the following broad questions. Are European and regional legislations substitutes for state laws? To what extent are the competences attributed by the European treaties or the Italian Constitution actually exerted in the various policy areas? Is their exertion consistent with the normative recommendations from the economic literature about their optimum allocation among different levels of government? The main results show that, first, there seems to be a certain substitutability between EU and national legislations (even if not a very strong one), but not between regional and national ones. Second, the EU concentrates its legislative activity mainly in international trade and agriculture, whilst social policy is where the regions and the State (which is also the main actor in foreign policy) are more active. Third, at least two levels of government (in some cases all of them) are significantly involved in the legislative activity in many sectors, even where the rationale for that is, at best, very questionable, indicating that they actually share a larger number of policy tasks than that suggested by the economic theory. It appears therefore that an excessive number of competences are actually shared among different levels of government. From an economic perspective, it may well be recommended that some competences be shared, but only when the balance between scale or spillover effects and heterogeneity of preferences suggests so. When, on the contrary, too many levels of government are involved in a certain policy area, the distinction between their different responsibilities easily becomes unnecessarily blurred. This may not only leads to a slower and inefficient policy-making process, but also risks to make it too complicate to understand for citizens, who, on the contrary, should be able to know who is really responsible for a certain policy when they vote in national,local or European elections or in referenda on national or European constitutional issues.

Effetti degli accordi Euro-Mediterrani sul comparto dell'ortofrutta fresca

In 1995, the European Union (EU) Member States and 12 Mediterranean countries launched in Barcelona a liberalization process that aims at establishing a free trade area (to be realized by 2010) and at promoting a sustainable and balanced economic development by the adoption of a new generation of Agreements: the Euro-Mediterranean Agreements (EMA). For the Mediterranean partner countries, the main concern is a better access for their fruit and vegetable exports to the European market. These products represent the main exports of these countries, and the EU is their first trading partner. On the other side, for the EU the main issue is not only the promotion of its products, but also the protection of its fruit and vegetables producers. Moreover, the trade with third countries is the key element of the Common Market Organization of the sector. Fruit and vegetables represent a very sensitive sector since their high seasonality, high perishability, and especially since the production of the Mediterranean countries is often similar to the European Mediterranean’s countries one. In fact, the agreements define preferences at the entrance of the EU market providing limited concessions for each partner, for specific products, limited quantities and calendars. This research tries to analyze the bilateral trade volume for fresh fruit and vegetables in the European and Italian markets in order to assess the effects of Mediterranean liberalization on this sector. Free trade of agricultural products represents a very actual topic in international trade and the Mediterranean countries, recognised as big producers of fruit and vegetables, as big exporters of their crops and actually significantly present on the European market, could be high competitors with the inward production because the outlet could be the same. The goal of this study is to provide some considerations about the competitiveness of mediterranean fruit and vegetables productions after Barcelona Process, in a first step for the European market and then also for the Italian one. The aim is to discuss the influence of the euro-mediterranean agreements on the fruit and vegetables trade between 10 foreign Mediterranean countries (Algeria, Egypt, Israel, Jordan, Libya, Lebanon, Morocco, Tunisia, Syria, and Turkey) and 15 EU countries in the period 1995-2007, by means of a gravity model, which is a widespread methodology in international trade analysis. The basic idea of gravity models is that bilateral trade from one country to another (as the dependent variable) can be explained by a set of factors: - factors that capture the potential of a country to export goods and services; - factors that capture the propensity of a country to imports goods and services; - any other forces that either attract or inhibit bilateral trade. This analysis compares only imports’ flows by Europe and by Italy (in volumes) from Mediterranean countries, since the exports’ flows toward those foreign countries are not significant, especially for Italy. The market of fruit and vegetables appears as a high heterogeneous group so it is very difficult to show a synthesis of the analysis performed and the related results. In fact, this sector includes the so called “poor products” (such as potatoes and legumes), and the “rich product”, such as nuts or exotic fruit, and there are a lot of different goods that arouse a dissimilar consumer demand which directly influence the import requirements. Fruit and vegetables sector includes products with extremely different biological cycles, leading to a very unlike seasonality. Moreover, the Mediterranean area appears as a highly heterogeneous bloc, including countries which differ from the others for economic size, production potential, capability to export and for the relationships with the EU. The econometric estimation includes 68 analyses, 34 of which considering the European import and 34 the Italian import and the products are examined in their aggregated form and in their disaggregated level. The analysis obtains a very high R2 coefficient, which means that the methodology is able to assess the import effects on fruit and vegetables associated to the Association Agreements, preferential tariffs, regional integration, and others information involved in the equation. The empirical analysis suggests that fruits and vegetables trade flows are well explained by some parameters: size of the involved countries (especially GDP and population of the Mediterranean countries); distances; prices of imported products; local production for the aggregated products; preferential expressed tariffs like duty free; sub-regional agreements that enforce the export capability. The euro-mediterranean agreements are significant in some of the performed analysis, confirming the slow and gradual evolution of euro- Mediterranean liberalization. The euro-mediterranean liberalization provides opportunities from one side, and imposes a new important challenge from the other side. For the EU the chance is that fruit and vegetables imported from the mediterranean area represent a support for local supply and a possibility to increase the range of products existing on the market. The challenge regards the competition of foreign products with the local ones since the types of productions are similar and markets coincide, especially in the Italian issue. We need to apply a strategy based not on a trade antagonism, but on the realization of a common plane market with the Mediterranean countries. This goal could be achieved enhancing the industrial cooperation in addition to commercial relationships, and increasing investments’ flows in the Mediterranean countries aiming at transforming those countries from potential competitors to trade partners and creating new commercial policies to export towards extra European countries.

Bridging innovation, nature and tradition: assessment of strategies for rural tourism development in Maramureş (Romania)

In the frame of EU rural policy, always more oriented towards environmental concerns and green livelihoods, Romania stands out for the predominance of rural areas and high nature value farming. The country has to face the challenge of joining the modernization process of rural farming systems with the valorization of local assets. Tourism has emerged as one of the main drivers of change and contributors for a sustainable exploitation of local resources. Rural tourism (RT) can foster the enhancement of the territorial capital (TC), the preservation of public goods (PGs) and the promotion of a more environmental oriented livelihood. The research focuses on a case study area, two valleys from Maramureş, where environmental approaches as diversification strategies are partially explored. The work investigates the role of tourism initiatives for the promotion of green oriented practices. The first part of the work is based on a literature review and interdisciplinary analysis of secondary data to identify the key issues: from rural development policy, to the concept of TC, of PGs and RT. The Romanian development programmes and related strategies are investigated; afterwards the characteristics of the County and the role of RT as diversification and valorisation policies is considered. The second part is based on the collection of primary data through interviews to different local stakeholders (farmers owners of rural guesthouses, local administrators, networks and artisans). The main frequencies are analyzed, a cluster analysis is computed to evaluate the similarities within the most representative groups and a comparative analysis is carried out between the two Valleys. The frame of the analysis is based on a set of indicators following the dimensions of the TC, to assess the characteristics of the local stakeholders and to outline the perception about the local PGs and on the adopted strategies to manage the territory. Final considerations are elaborated and few scenarios are outlined, giving relevance to the importance of improving awareness and creating embeddedness among public-private local stakeholders and resources as a tool for a socio-economic and environmental development of the area.

I beni relazionali nella ricerca sociologica: che cosa sono e quali effetti producono

This paper studies relational goods as immaterial assets creating real effects in society. The work starts answering to this question: what kind of effects do relational goods produce? After an accurate literature examination we suppose relational goods are social relations of second order. In the hypotesis they come from the emergence of two distinct social relations: interpersonal and reflexive relations. We describe empirical evidences of these emergent assets in social life and we test the effects they produce with a model. In the work we focus on four targets. First of all we describe the emergence of relational goods through a mathematical model. Then we individualize social realities where relational goods show evident effects and we outline our scientific hypotesis. The following step consists in the formulation of empirical tests. At last we explain final results. Our aim is to set apart the constitutive structure of relational goods into a checkable model coherently with the empirical evidences shown in the research. In the study we use multi-variate analysis techniques to see relational goods in a new way and we use qualitative and quantitative strategies. Relational goods are analysed both as dependent and independent variable in order to consider causative factors acting in a black-box model. Moreover we analyse effects of relational goods inside social spheres, especially in third sector and capitalistic economy. Finally we attain to effective indexes of relational goods in order to compare them with some performance indexes.

Interventi normativi, interni ed uniformi, dettati dalle nuove esigenze e dai nuovi quesiti posti dalla modernizzazione dei traffici, con particolare riferimento al trasporto containerizzato e multimodale

Come si evince dal titolo della tesi, la ricerca effettuata dal presente candidato nel corso del dottorato di ricerca ha avuto ad oggetto lo studio della materia relativa ai trasporti nell’ambito di diversi sistemi giuridici europei, con particolare attenzione ai risvolti di carattere pratico che l’interpretazione delle normative uniformi poteva produrre nell’ambito delle diverse giurisdizioni nonché alle diverse impostazioni e alla variegata gamma di soluzioni interpretative che nell’ambito di problemi simili possono essere adottate a seconda che una stessa questione venga discussa in un ordinamento piuttosto che in un altro. Dall’avvento del trasporto marittimo di containers alla necessità di disciplinare l’intera materia attraverso una normativa multimodale il passo è estremamente breve, posto che, proprio in considerazione delle caratteristiche proprie del trasporto containerizzato, gli aventi diritto al carico sono principalmente interessati al completamente del trasferimento door-to-door inteso nella sua globalità, piuttosto che al buon esito del trasporto sulla singola tratta marittima. Il progetto di revisione delle Regole dell’Aja-Visby adottato dall’United Nations Commission on International Trade Law (Uncitral) e il Comité Maritime International (CMI) costituisce per definizione un progetto limitato ad un trasporto multimodale comprendente necessariamente una tratta marittima, ma rappresenta comunque un interessante banco di prova per valutare la funzionalità di strumenti di recente impiego, come ad esempio i cosiddetti e-documents, concetto peraltro già inserito nel progetto UNCITRAL, anche se con scarsi elementi di reale novità rispetto alla tradizionale disciplina relativa ai documenti cartacei. Proprio la parte relativa ai documenti e titoli di viaggio merita particolare attenzione soprattutto in riferimento alle problematiche connesse al traffico containerizzato, con particolare riferimento al concetto di transhipment, e alla conseguente necessità che la polizza garantisca al legittimo portatore una copertura completa sull’intero viaggio della merce, oltre a dargli la possibilità di individuare agevolmente la propria controparte contrattuale, e cioè il vettore.

La responsabilità del vettore terrestre nel trasporto di cose per conto terzi: riflessi assicurativi.

La ricerca ha ad oggetto l’analisi della disciplina della responsabilità del vettore terrestre di merci per conto terzi ed i riflessi che detta disciplina ha avuto modo di svilupparsi nel mercato assicurativo. L’attenzione è stata rivolta al contratto di trasporto di cose in generale, seguendone la disciplina codicistica e le evoluzioni legislative intervenute. Particolare rilievo assume la novella apportata all’art. 1696 c.c., introdotta dall’art. 10 del Dlgs. 286/2005, grazie alla quale l’ordinamento italiano ha potuto codificare il limite di indennizzo dovuto dal vettore nell’ipotesi di colpa lieve, L’introduzione del limite legale di indennizzo per le ipotesi di responsabilità per perdita o avaria della merce trasportata ha generato nel mondo assicurativo interessanti reazioni. L’elaborato esamina anche l’evoluzione giurisprudenziale formatisi in tema di responsabilità vettoriale, evidenziando il crescente rigore imposto dalla giurisprudenza fondato sul principio del receptum. Tale fenomeno ha visto immediata reazione nel mercato assicurativo il quale, sulla base di testi contrattuali non dissimili tra le diverse compagnie di assicurazioni operanti sul mercato domestico e che traevano origine dai formulari approvati dall’ANIA, ha seguito l’evoluzione giurisprudenziale apportando significative restrizioni al rischio tipico previsto dalle coperture della responsabilità civile vettoriale. La ricerca si è poi focalizzata sull’esame delle più comuni clausole contemplate dalle polizze di assicurazioni di responsabilità civile e sul loro significato alla luce delle disposizioni di legge in materia. Tale analisi riveste preminente interesse poiché consente di verificare in concreto come l’assicurazione possa effettivamente costituire per l’impresa di trasporto non tanto un costo bensì una opportunità di risparmio da un lato ed un modello comportamentale, sebbene indotto, dall’altro lato per il raggiungimento di quei canoni di diligenza che qualsiasi operatore del settore dovrebbe tenere durante l’esecuzione del trasporto ed il cui venir meno determina, come detto, sensibili effetti pregiudizievoli di carattere economico.

El principio de neutralidad interna en el IVA

La tesis estudia el principio de neutralidad en su vertiente interna y su aplicación efectiva en el IVA. Se centra en los principales aspectos de la configuración jurídica del impuesto: derecho de deducción, exenciones y tipos reducidos. Se realiza en primer lugar una aproximación teórica al principio desde un punto de vista jurídico y también económico. Una vez construido el principio se acomete una comparación de las distintas clases de impuestos indirectos que pueden establecerse y se analiza su cumplimiento del principio de neutralidad fiscal. El énfasis es mayor en los impuestos en cascada, impuestos monofásicos minoristas y en el IVA. El objetivo de la tesis es, por tanto, concretar el contenido del principio, desarrollar sus implicaciones económicas principales y analizar el grado de cumplimiento real de la Directiva IVA. Desde el punto de vista del derecho de deducción y de las exenciones el estudio se apoya en el análisis de la jurisprudencia del Tribunal de Justicia de la Unión Europea, donde se profundizará en cuestiones como la utilización de bienes de uso mixto, la consideración de costes como directos o generales y las formas de ejercicio del exceso de deducción (devolución y compensación). Además, la tesis muestra las principales excepciones al principio de neutralidad establecidas en la Directiva IVA: prohibiciones al derecho de deducción, exenciones y tipos reducidos. En esta parte también se apoyará el estudio en la jurisprudencia del TJUE, que ha construido en gran medida los criterios de interpretación de estas excepciones. En conclusión, el objetivo de la tesis es medir si la directiva IVA cumple con el principio de neutralidad fiscal, para lo que deberá haberse especificado primero su significado concreto y se habrá debido diferenciar entre sus dos dimensiones: interna y externa.

La gestione dei beni fiscali da parte di Federico II di Svevia: Il "Quaternus excadenciarum capitinate". Edizione e commento

La ricerca è stata incentrata su di una fonte di grande importanza per una più puntuale comprensione della vita del regno di Federico II: il Quaternus excadenciarum Capitinate. Essa ha tenuto presenti le altre fonti coeve: Liber Augustalis, Registro della Cancelleria di Federico II degli anni 1239-1240, fonti cronachistiche. Il Quaternus è un inventario di talune particolari categorie di beni demaniali, le excadencie, la cui concessione è scaduta e pertanto ritornano al fisco. Tali beni sono situati in 33 località del Giustizierato di Capitanata. Senza data, è stato redatto tra il 1249 e il 1250 (risultano inseriti i beni confiscati a Pier della Vigna, bollato di tradimento nel febbraio 1249). Obiettivo della ricerca è stato duplice: 1) analizzare e approfondire le questioni di natura giuridico-istituzionale ed economica implicate nel documento e tentare di ricostruire uno spaccato della Capitanata del XIII sec.; 2) offrire una nuova e più corretta edizione del testo. La prima parte dello studio ha inteso inquadrare il documento nel contesto delle esigenze proprie delle monarchie del tempo di tenere sotto controllo i beni immobili di ciascun regno ed analizzare la politica economica fridericiana (capp. I, II). La seconda parte è stata dedicata agli approfondimenti innanzi ricordati. Essa è struttura in sette capitoli (I. Il Quaternus excadenciarum Capitinate; II. Beni e diritti costituenti le excadencie Capitinate; III. Il Quaternus come specchio di una politica dispotica; IV. La gestione delle excadencie; V. Pesi e misure; VI. Monete e valori; VII. Il Quaternus come documento sullo stato della Capitanata nel XIII secolo). In appendice: tabelle che offrono per ciascuna delle 33 località considerate, puntuali indicazioni dei beni e diritti censiti, dei nomi dei titolari delle concessioni (spesso personaggi di rango) e delle relative rendite.

Linking rural tourism to agriculture. Evidences from comparative case studies in Kosovo, Italy and Spain

Rural tourism has been widely promoted in the European Union as an effective measure counteracting economic and social challenges facing rural areas especially those with declining agriculture economies. Particularly its role is seen in provision and maintenance of public goods which are more and more demanded by the public and considered in the policymaking. In Kosovo, rural tourism has been developed through the support of the international organizations and private sector initiatives, with primary aim to generate additional income for rural households and sustainable management of natural and cultural resources. Anyhow, it could be stated that the use of territorial capital to enhance the quality of the tourist offer and undertake promotion at wider circles of people has not been well explored so far, particularly possible links with agriculture that would satisfy visitors demand. In this regard this research study analyzes involvement of local stakeholders and use of territorial capital to develop tourist offer in rural areas of Kosovo. Beside, study applies comparative approach with other two areas of the European Union, Appennino Bolognese in Italy and Alpujara in Spain, to understand and compare the process of rural tourism development and demand characteristics between Kosovo and these areas. A survey has been conducted in all three study areas with rural tourism visitors to understand their preferences for public and private goods and services when visiting rural areas and the role of agriculture in sustaining rural tourism. Results show that there is a potential to link rural tourism with agriculture in Kosovo, which would help in sustaining agriculture and add additional value to local food products, which in return would enhance the tourist offer and make it more attractive for the visitors but also for the farmers as an additional revenue generating sector.
