The long breadth of cities: revisiting worldwide urbanization patterns, 1950–2030

ABSTRACT

A comparative analysis of population dynamics worldwide contributes to profile distinctive demographic and economic trajectories of urban growth, discriminating processes of settlement concentration or dispersion under sequential cycles of urbanization. However, a wide-ranging characterization of urban cycles based on demographic dynamics worldwide is still missing. The present work is aimed at filling such a gap analysing long-term changes (1950–2030) in annual population growth rate of 1691 urban agglomerations with more than 300,000 inhabitants in 74 world countries. Results of this study indicate that metropolitan growth worldwide was associated with largely variable rates of population growth, highly positive before 2000 and progressively reducing over recent decades. Despite important differences at continental (and country) scale, demographic expansion of urban agglomerations showed two contrasting phases with a break point in the 1980s denoting a progressive reduction in spatial heterogeneity of population growth rates and a moderate slowdown in demographic dynamics. Intensity of urban expansion and spatial heterogeneity in population growth rates across metropolitan agglomerations evidences a trade-off between fast and slow demographic dynamics. These findings can be better understood to support theories of sequential city growth, making a suitable contribution to policy making, especially in countries where urban population is expanding more rapidly.     

The value of natural resources for tourism: a case study of the Italian Alps

The paper deals with the measurement of the benefits provided by natural resources, with particular reference to the tourist development of mountain areas. In fact, the possibility of measuring some of the benefits produced by the natural resources allows appropriate development strategies to be formulated. The second part of the paper presents possible solutions suggested for sustainable tourism in an area of the Pre‐Alps between Veneto and Trentino. These solutions are a result of research carried out using the contingent valuation method. Critical information was gathered that enabled the adjustment of interventions in relation to both the actual opportunity and the benefits deriving from the natural resources studied.

New development: Estate agents’ perspectives of anti-money laundering compliance—four key issues in the UK property market

ABSTRACT

In recent years, money laundering in the property market has come under scrutiny across the world, attracting significant attention from governments, regulators, policy-makers, NGOs, academics and others. However, there remain gaps in knowledge, which is particularly important given practical difficulties in the implementation of anti-money laundering (AML) obligations. This article offers new insights into such implementation in the context of the UK AML regime and the real estate sector. The authors analyse four important issues relating to the UK AML obligations: customer due diligence (CDD); reporting suspicion; training requirements; and letting (rental) agents.     

The impact of outward FDI on the home country's labour demand and skill composition

The present paper adds to the literature investigating the effects of outward FDI on the home country employment and skill composition. Considering the “industrial region” as the unit of the analysis, we capture both direct and indirect effects of foreign production on the parent company and its environment. The empirical evidence refers to the internationalisation of production by Italian firms throughout the period 1996–2002, and it shows that foreign activities have a negative impact upon the demand for low skilled workers in the parent company's “industrial region”, but also on the demand for high skilled workers when FDI are addressed to high income countries.     

Strategic Ignorance as a Self-Disciplining Device

We analyse the decision of an agent with time-inconsistent preferences to consume a good that exerts an externality on future welfare. The extent of the externality is initially unknown, but may be learned via a costless sampling procedure. We show that when the agent cannot commit to future consumption and learning decisions, incomplete learning may occur on a Markov perfect equilibrium path of the resulting intra-personal game. In such a case, each agent's incarnation stops learning for some values of the posterior distribution of beliefs and acts under self-restricted information. This conduct is interpreted as strategic ignorance. All equilibria featuring this property strictly Pareto dominate the complete learning equilibrium for any posterior distribution of beliefs.     

Firm size and the adoption of flexible automation

Data on the diffusion of flexible automation systems in the Italian metalworking industry are used to point out the role of size for the adoption of complex, systemic innovations. Plant and firm sizes turn out to be positively correlated to adoption rates. Moreover, adoption is more likely, ceteris paribus, in plants which are part of large industrial groups. This pattern applies in general, and is particularly remarkable for more advanced solutions. In this light, guidelines for industrial policies that focus on financial support, the diffusion of industrial standards, and the correction of asymmetries in the availability of know-how and skills are proposed.Financial support for this paper was provided by the Ministero della Pubblica Istruzione (MPI 40% research funds). Grants from the Fondazione Mauro and the CNR research project Tecnologie Meccaniche are also acknowledged. The research took advantage of the FLAUTO database, set up at the Laboratorio di Economia dei Processi di Automazione, MIP-Politecnico di Milano.     

From 'A Frontier Land' to 'A Piece of North Africa in Italy': The Changing Politics of 'Tunisianness' in Mazara del Vallo,Sicily

This article analyzes the conditions leading to the ‘ethnic packaging' of the Casbah neighborhood in Mazara del Vallo, Sicily, and the economic and political struggles that ensued. By studying the changing relationship between the neighborhood's built environment, the racialization of Tunisian migrants and the town's transitioning economy, it analyzes transformations of the Casbah from a working‐class Sicilian neighborhood, to an ‘insanitary' Tunisian ghetto, to a showcase of the town's Mediterranean multiculturalism. Through this analysis, the article makes three arguments. Firstly, by showing that ‘ethnic packaging' does not always lead to gentrification but may engender other types of conflict, it argues that the ‘marketization' of urban diversity has a variety of consequences tied to cities' positions in broader geographies of uneven development. Secondly, by showing that the changing racialization of Tunisian migrants was produced both through changes to Mazara's built environment and through shifting territorial relations within Italy and across the Mediterranean, it develops a multi‐scalar analysis of racialization. Thirdly, by showing that Sicilian depictions of Tunisian migrants changed according to shifting understandings of Sicilian modernity vis‐à‐vis the north of Italy, it argues that Italian immigration discourses develop in relation to internal forms of ‘othering' of southern Italians.     

A "Tragedy of the Clubs": Excess Entry in Exclusive Coalitions

We model club formation as a noncooperative game of coalition formation and surplus division. We show how social norms and individual rationality sustain a particular type of collective inefficiency, namely, excessive entry in the joint production and exploitation of an excludable good. We term this phenomenon the "tragedy of the clubs." The tragedy of the clubs is a pervasive equilibrium phenomenon.     

Auction and the informed seller problem

A seller possessing private information about the quality of a good attempts to sell it through a second-price auction with announced reserve price. The choice of a reserve price transmits information to the buyers. We characterize the equilibria with monotone beliefs of the resulting signaling game and show that they lead to a reduced probability of selling the good compared to the symmetric information situation. We compare the unique separating equilibrium of this signaling game to the equilibrium of a screening game in which an uninformed monopoly broker chooses the trading mechanism. We show that the ex ante expected probability of trade may be larger with a monopoly broker, as well as the ex ante total expected surplus.
