A note on the empirics of the neoclassical growth model
No full textThis paper shows that the widely used log-linearization of the neoclassical model of growth implies a relevant loss in terms of the ability of the model in replicating the patterns of convergence of an economy to its equilibrium level
International Output Convergence: Evidence from an AutoCorrelation Function Approach
No full textThis paper uses an autocorrelation function (ACF) approach to develop a new testing procedure for international Output convergence. We define convergence in terms of sample ACFs of detrended Output per capita, and construct an inference set-up based on resampling and subsampling techniques for dependent data. Using per capita GDP for 15 OECD countries observed over a century, we find that the hypothesis of conditional convergence is unsupported; that, the USA apart, the linearized neoclassical growth model fails to replicate the transitional dynamics of OECD economics; and that these economies do not behave like a Club
Multimodality in the distribution of GDP and the absolute convergence hypothesis
No full textThis article shows that, contrary to common wisdom, the insurgence of a multiplicity of clusters in the distribution of income is not necessarily against the hypothesis of absolute convergence. Using data for the world economies, the US states, the EU regions, and the Italian regions, we find that despite the distribution of income per capita for both the world economies and for the Italian regions is multimodal, only in the former case absolute convergence can be rejected. Similarly, although the distributions for the EU regions and the US states are both unimodal, convergence is unambiguously taking place in the latter case only. We show that these results are consistent with the neoclassical model of growth in the presence of non-convexities in production. We conclude that polarization in the distribution of per capita incomes is neither a sufficient nor a necessary condition to reject the absolute convergence hypothesis
The Evidence of the Environmental-Economic Transition Hypothesis: a Semi-Parametric Approach
No full textA Semi-Parametric Analysis on Carbon Oxide Distribution
No full textThe purpose of the present work is to study the distribution of carbon monoxide
emissions among European Countries at NUTS level 2. By applying a nonparametric
technique and accurately weighting the sample observed, it is possible
to study the effects of sectoral composition of GDP, the localisation factors for the
Objective 1 Regions of the European Structural Fund Framework and growth rates
on the entire distribution of the environmental pollutant. Results suggest the
presence of a bimodal distribution for carbon monoxide emissions that would
confirm: 1) the highest concentration of the pollutant in highly populated urban
centres and 2) the influence of the industrial and agricultural sector on the entire
distribution
Opportunism and MPs’ chances of re-election: an analysis of political transformism in the Italian parliament
Get PDFWe identify as political transformists the Italian members of parliament (MPs) who cross the aisle and vote for legislation opposed by their own political group—i.e., MPs who transform from the political opposition to the ruling parties (or from government supporters) into a force supporting the government (or opposition)—thus representing sources of party and governmental instability. Transformism, which characterized 471 MPs over the period considered, does not coincide with the broader phenomena of party switching already studied in political science. Once we disentangle the distinct behaviors, we study whether transformism helps extend the tenures of all 7128 MPs observed from 1946 to 2013. To the best of our knowledge, ours is the first work to consider the role of transformism in the survival of politicians. Our results suggest that transforming MPs suffer marked reductions in their survival probabilities, especially when compared with their fellow parliamentarians. However, transformist MPs, immediately after coming out as such, are more likely to survive than MPs remaining reliably loyal to their parties. That is, over time, transformists are punished by the electorate, but newly transformed politicians enjoy short-term comparative electoral advantages, thus shedding light on the relevance of a long-standing Italian political phenomenon
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
