Cultural Diversity and Economic Performance: Evidence from European Regions

We investigate the relationship between diversity and productivity in Europe using an original dataset covering the NUTS 3 regions of 12 countries of the EU15 (Austria, Belgium, Denmark, France, former Western Germany, Ireland, Italy, the Netherlands, Portugal, Spain, Sweden and the United Kingdom). In so doing, we follow the empirical methodology developed by Ottaviano and Peri (2006a) in the case of US cities. The main idea is that, as cultural diversity may affect both production and consumption through positive or negative externalities, the joint estimation of price and income equations is needed to identify the dominant effect. Based on this methodology, we find that diversity is positively correlated with productivity. Moreover, we find evidence that causation runs from the former to the latter. These results for EU regions are broadly consistent with those found by Ottaviano and Peri for US cities.

Poor Institutions, Rich Mines: Resource Curse and the Origins of the Sicilian Mafia

This study explains the emergence of the Sicilian mafia in the XIX century as the product of the interaction between natural resource abundance and weak institutions. We advance the hypothesis that the mafia emerged after the collapse of the Bourbon Kingdom in a context characterized by a severe lack of state property-right enforcement in response to the rising demand for the protection of sulfur - Sicilys most valuable export commodity - whose demand in the international markets was soaring at the time. We test this hypothesis combining data on the early presence of the mafia and on the distribution of sulfur reserves across Sicilian municipalities and find evidence of a positive and significant effect of sulphur availability on mafias diffusion. These results remain unchanged when including department fixed-effects and various geographical and historical controls, when controlling for spatial correlation, and when comparing pairs of neighboring municipalities with and without sulfur.

Cultural Identity and Knowledge Creation in Cosmopolitan Cities

We study how the city system is affected by the possibility for the members of the same cultural diaspora to interact across different cities. In so doing, we propose a simple two-city model with two mobile cultural groups. A localized externality fosters the productivity of individuals when groups interact in a city. At the same time, such interaction dilutes cultural identities and reduces the consumption of culture-specific goods and services. We show that the two groups segregate in different cities when diaspora members find it hard to communicate at distance whereas they integrate in multicultural cities when communication is easy. The model generates situations in which segregation is an equilibrium but is Pareto dominated by integration.

A Politico-Economic Model of Aging, Technology Adoption and Growth

Over the past century, all OECD countries have been characterized by a dramatic increase in economic conditions, life expectancy and educational attainment. This paper provides a positive theory that explains how an economy might evolve when the longevity of its citizens both influences and is influenced by the process of economic development. We propose a three periods OLG model where agents, during their lifetime, cover different economic roles characterized by different incentive schemes and time horizon. Agents’ decisions embrace two dimensions: the private choice about education and the public one upon innovation policy. The theory focuses on the crucial role played by heterogeneous interests in determining innovation policies, which are one of the keys to the growth process: the economy can be discontinuously innovation-oriented due to the different incentives of individuals and different schemes of political aggregation of preferences. The model produces multiple development regimes associated with different predictions about life expectancy evolution, educational investment dynamics, and technology adoption policies. Transitions between these regimes depend on initial conditions and parameter values.

Intellectual Property Rights and South-North Formation of Global Innovation Networks

With the rise of the knowledge economy; delivering sound innovation policies requires a thorough understanding of how knowledge is produced and diffused. This paper takes a step to analyze a new form of globalization; the so-called system of Global Innovation Networks (GINs); to shed light on how the protection of intellectual property rights (IPRs) influences their creation and development. We focus on the role of IPR protection in fostering international innovative activities in emerging economies (South); such as China and India; and more generally; how IPRs affect the development of GINs between newly industrialized countries and OECD countries. Using both survey-based firm-level and country-level global data; we find IPRs to be an important determinant of participation in GINS from a Southern perspective. We find IPR protection at home and its harmonization across county pairs foster South-North formation of GINs. We also find that a stringent regime in the destination country discourages foreign international innovative activities that originate in NICs. Both levels of our analysis confirm the ICT industry; particularly the hardware segment; to rely on IPRs when engaging in the international outsourcing and offshoring of innovation or in patenting activities abroad.

On the Historical and Geographic Origins of the Sicilian Mafia

This research attempts to explain the large differences in the early diffusion of the mafia across different areas of Sicily. We advance the hypothesis that, after the demise of Sicilian feudalism, the lack of publicly provided property-right protection from widespread banditry favored the development of a florid market for private protection and the emergence of a cartel of protection providers: the mafia. This would especially be the case in those areas (prevalently concentrated in the Western part of the island) characterized by the production and commercialization of sulphur and citrus fruits, Sicilys most valuable export goods whose international demand was soaring at the time. We test this hypothesis combining data on the early incidence of mafia across Sicilian municipalities and on the distribution of sulphur reserves, land suitability for the cultivation of citrus fruits, distance from the main commercial ports, and a variety of other geographical controls. Our empirical findings provide support for the proposed hypothesis documenting, in particular, a significant impact of sulphur extraction, terrain ruggedness, and distance from Palermos port on mafias early diffusion.

The Sustainability of Cultural Diversity

This book, The Sustainability of Cultural Diversity, brings together a series of contributions from different disciplines and in different cultural settings with the aim of increasing our understanding of the functioning of cultural diversity. It represents the insights of more than 30 scholars around Europe and beyond, having studied cultural diversity extensively in their own university or institution as well as exchanged their research results and knowledge in the SUS.DIV network of excellence over a period of five years. It is the strong belief of the SUS.DIV Network of Excellence that, as emphasized in Chapter 1, no single discipline or perspective can explain sustainable diversity in a comprehensive way. At the same time, though, this book is neither presenting nor striving for a framework representing all important dimensions and processes of sustainable diversity. Such a framework would imply assimilation of the different disciplinary perspectives into one overarching way of thinking, which would imply a loss of the variety and specificity of each discipline as well as of the cultural setting of the study. Rather, this collection of chapters has the aim of advancing knowledge in the area of diversity and sustainability through presenting different insights in such a way that it allows further comparing, contrasting and combining. As a reader, you will encounter a variety of studies which are connected by two central questions: 1) how does cultural diversity contribute (or not) to central notions of sustainability such as human welfare, development, social cohesion, or socio-economic integration? and 2) How can we create spaces and communities where cultural diversity can unfold in a positive way through particular forms of cultural interactions and processes as well as types of initiatives and structures? The chapters address these two central questions in three arenas: nations, cities and organizations.

Trade and Geography in the Economic Origins of Islam: Theory and Evidence

This research examines the economic origins of Islam and uncovers two empirical regularities. First, Muslim countries, virtual countries and ethnic groups, exhibit highly unequal regional agricultural endowments. Second, Muslim adherence is systematically larger along the pre-Islamic trade routes in the Old World. The theory argues that this particular type of geography (i) determined the economic aspects of the religious doctrine upon which Islam was formed, and (ii) shaped its subsequent economic performance. It suggests that the unequal distribution of land endowments conferred differential gains from trade across regions, fostering predatory behavior from the poorly endowed ones. In such an environment it was mutually beneficial to institute a system of income redistribution. However, a higher propensity to save by the rich would exacerbate wealth inequality rendering redistribution unsustainable, leading to the demise of the Islamic unity. Consequently, income inequality had to remain within limits for Islam to persist. This was instituted via restrictions on physical capital accumulation. Such rules rendered the investments on public goods, through religious endowments, increasingly attractive. As a result, capital accumulation remained low and wealth inequality bounded. Geography and trade shaped the set of economically relevant religious principles of Islam affecting its economic trajectory in the preindustrial world.

Persistence of Politicians and Firms' Innovation

We empirically investigate whether the persistence of politicians in political institutions affects the innovation activity of firms. We use 12,000 firm-level observations from three waves of the Italian Observatory over Small and Medium Enterprises, and introduce a measure of political persistence defined as the average length of individual political careers in political institutions of Italian municipalities. Standard OLS shows no raw correlation between political persistence and firms’ innovation activity. However, once the causal effect is isolated by means of instrumental variables, using death of politicians as an exogenous source of variation of political persistence, we find a robust negative relation between political persistence and the probability of process innovation. This finding is consistent with the view that political stability may hinder firms’ incentive to innovate to maintain their competitiveness, as long as they can extract rents from long-term connections with politicians.

One More in My Backyard? Insights from the 2011 Italian Nuclear Referendum

This paper investigates the 2011 Italian referendum on nuclear power as a clean laboratory for recovering information on the spatial pattern of votes about the construction (or restoration) of nuclear facilities. Our results show that voting preferences on building nuclear facilities are sensible to proximity determined by a strong local component. Voters’opposition to nuclear installments tends to be even higher when the effect of both existing and proposed plants is taken into account. The study tracks the changes of risk perception and voting preferences finding a positive correlation between the distance-related perceived nuclear risk and the share of participation against nuclear power. The perceived risk and the consequent voting pattern are even higher in communities close to proposed nuclear plants compared to the existing ones. This holds even after taking into account local, regional and political features and several municipality characteristics which may influence preferences over nuclear power.
