Regional Patterns in the Achievement of the Lisbon Strategy: a Comparison Between Polycentric Regions and Monocentric Ones
Full text linkPolycentrism is a common feature of European urban systems. Lately, the concept has assumed a more normative relevance and it has been often considered as a pre?requisite for a more sustainable and balanced development across Europe. However, the effects of polycentrism on other main European Strategies (such as the Lisbon Strategy, aimed at increasing European competitiveness and social cohesion) are not so clear. Therefore, the paper tries to highlight the relationships between a regional polycentric development and the achievement of the Lisbon Strategy’s targets. Referring to a sample of 75 regions belonging to France, Germany, Italy and Spain, we have first measured the extent of polycentrism, by estimating through OLS the slope of the rank-size distribution of cities within each region. Then, we have performed a principal component analysis (PCA) in order to highlight the main features characterising the performance of each region according to Lisbon Strategy’s targets. Looking at the correlations between the extent of polycentrism and the achievement of the Lisbon Strategy’s targets, we have found that the former is significantly correlated both with the spread of manufacture and with low investments in human capital and innovationthe Lisbon Strategy, polycentrism, rank-size distribution, PCA
From SHIW to IT-SILC: Construction and Representativeness of the New CAPP_DYN First-Year Population
Full text linkThis paper describes the construction of the initial population in CAPP_DYN and illustrates the degree of representativeness of the Italian population in 2006. While the previous version of the model was constructed using the Bank of Italy Survey on Household Income and Wealth, the current version is based on the new ISTAT Survey on Income and Living Conditions. The first part of the paper discusses the reasons that led us to this switch. It also provides full details on the operations carried out on the original dataset in order to obtain a sample that can be used as the first year population of the Dynamic Simulation Model. In the second part of the paper, the demographic and socio-economic characteristics of the initial population sample are compared with information coming from other sources, such as administrative archives, national accounts and Labour Force Surveys. This exercise is crucial in assessing the capability of CAPP_DYN to represent the population's characteristics at the starting pointDynamic micro-simulation; model validation; income distribution; pensions and social security
Transnational social capital and FDI.Evidence from Italian associations worldwide
Full text linkEmigrant associations abroad are structured nodes of social networks; they are manifestations of a transnational social capital. Italian associations are numerous, spread across several countries, in some cases they exist since the end of the nineteenth century, and may count on high numbers of members. Also, they are robustly tied to the home country. This paper assesses the effects of Italian associations abroad on the bilateral FDI between Italy and the countries of settlement of Italian diaspora. The main results are that these effects are positive and strongly significant, especially for the inward FDI and relatively to the countries with the oldest associationsinternational migration, FDI, Italy
Dynamic Adverse Selection and the Size of the Informed Side of the Market
Full text linkIn this paper we examine the problem of dynamic adverse selection in a stylized market where the quality of goods is a seller’s private information. We show that in equilibrium all goods can be traded if a simple piece of information is made publicly available: the size of the informed side of the market. Moreover, we show that if exchanges can take place frequently enough, then agents roughly enjoy the entire potential surplus from exchanges. We illustrate these findings with a dynamic model of trade where buyers and sellers repeatedly interact over time. More precisely we prove that, if the size of the informed side of the market is a public information at each trading stage, then there exists a weak perfect Bayesian equilibrium where all goods are sold in finite time and where the price and quality of traded goods are increasing over time. Moreover, we show that as the time between exchanges becomes arbitrarily small, full trade still obtains in finite time – i.e., all goods are actually traded in equilibrium while total surplus from exchanges converges to the entire potential. These results suggest two policy interventions in markets suffering from dynamic adverse selection: first, the public disclosure of the size of the informed side of the market in each trading stage and, second, the increase of the frequency of trading stagesdynamic adverse selection; full trade; size of the informed side; frequency of exchanges; asymmetric information
Estimation and Simulation of Earnings in IT-SILC
Full text linkThis paper describes income distribution among workers in Italy using both the cross-sectional and panel component of IT-SILC. We highlight advantages and drawbacks of different econometric approaches, comparing standard OLS estimates with those obtained from Random Effects and Poisson Maximum Likelihood and assessing whether the results are sensitive to the different specification. Finally, we present the procedure in use in simulating future earnings in CAPP_DYN, the dynamic population-based microsimulation model of the CAPPMicrosimulation; Earnings; Lifetime; Inequality; IT-SILC
Exports and Italy’s economic development: a long-run perspective (1863-2004)
Full text linkThis paper investigates the relationship between real export and real GDP in Italy from 1863 to 2004 by using cointegration analysis and causality tests. The outcome suggests that these variables comove in the long run but the direction of causality depends on the level of economic development: in the period prior to WW1 the growth of the Italian economy led that of exports, while in the post-WW2 period the causal relationship was reversed with the expansion of exports that determined the growth of the Italian economyExport led growth hypothesis, unit root tests, cointegration analysis, Granger – causality
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
