Impact analysis of regional knowledge subsidy: a CGE approach
No full textIn this paper we present a computable general equilibrium model for the region
of Sardinia for the purpose of evaluating the capacity of R&D policies to affect the
long run rate of growth. The model incorporates induced technical change and allow
for external knowledge spillovers. We find that the cost of R&D policies may
change according to the wage setting prevailing into the region. Furthermore, the
capacity of such a policy to generate knowledge spillovers from the international and
interregional trade are quite modest. Indeed, the capacity of the regional system to
internalize the technological level embody in the imported good is partially offset by
an increase in internal efficiency lowering the share of import but increasing
competitiveness
Does deflation method matter for productivity measures?
Get PDFIn this paper, we argue against the use the double deflation method to produce an equilibrating system of account at a constant price. In fact, by relaxing such a condition, by means of the single deflation method, we obtain a measure of purchasing power transfer that can be decomposed in productivity and market distortion. Results are presented for the evolution of the Italian economy for the periods 1995-2002
Capital-skill complementarity and regional inequality: A spatial general equilibrium analysis
No full textThis paper employs a large scale numerical spatial general equilibrium model featuring capital-skill complementarities in production to study the distributional implications of a capital-augmenting technological shift across regions and skills groups. Similarly to the existing literature, we find a negative relationship between the labour income share and the capital labour-ratio. Our counterfactual shows that the effects are quite uneven across skills and regions, benefiting mostly high-skilled workers at the detriment of the low and the medium skilled. This is particularly so in more developed regions compared with less developed ones. We show that the effects stem from regional initial conditions, and in particular the regional capital–labour ratio, trade linkages and unemployment rates
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
Three essays on policy modelling : an inter-temporal computable general equilibrium approach
Get PDFThe thesis contains three independent essays on policy modelling. In all three, a numerical dynamic general equilibrium framework is used to discuss methodological advances in regional economic modelling and to analyse specific policies for the economies of Sardinia, Scotland and the United Kingdom respectively. In the first essay, I present a stylized regional intertemporal forward-looking model able to take into account regional economic features. Furthermore, I discuss some of the objections to myopic models, such as the presumed lack of capital adjustment and the differences in the long-run steady-state results between myopic and forward- looking models. I show that properly specified myopic and forward looking models produce identical results in the long run, in contrast to claims in some of the literature in this area. In the second essay I investigate the impact of a balanced budget fiscal policy expansion. I take Scotland as an example where, recently, there has been extensive debate on greater fiscal autonomy. In response to a balanced budget fiscal expansion the model suggests the following results. First, an increase in current government purchases of goods and services has negative multiplier effects only if the elasticity of substitution between private and public consumption is high enough to reduce the marginal utility of private consumers. Second, public capital expenditure crowds in consumption and investment even with a high level of congestion. Third, crowding out effects might arise in the short-run if agents are myopic. CGE modelling techniques have been widely used in the literature to examine the rebound effect in an economy wide context. However, most of the studies focus on economy-wide rebound from an energy efficiency improvement on the production side of the economy. In the third essay, I present simulation results for an improvement in energy efficiency in the household sector which is a clear example of a demand side shock where households take all prices as given and with limited supply side effects.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
