Inflation persistence in Central and Eastern European countries
Full text linkThis article studies inflation persistence with time-varying coefficient autoregressions for
twelve central European countries, in comparison with the United States and the euro area.
Inflation persistence tends to be higher in times of high inflation. Since the oil price shocks,
inflation persistence has declined both in the US and the euro-area. In most central and
eastern European countries, for which our study covers 1993-2012, inflation persistence has
also declined, with the main exceptions of the Czech Republic, Slovakia and Slovenia, where
persistence seems to be rather stable. These findings have implications for the conduct of
monetary policy and for a possible membership in the euro area. We also conclude that the
OLS estimate of an autoregression is likely upward biased relative to the time-average of
time-varying parameters, when the parameters change

Labour taxation and employment in trade union models: A partial survey
Full text linkThis paper uses a union bargaining framework, where the wage rate is negotiated between the representatives of employees and employers and firms unilaterally determine employment, to discuss the relationship between labour taxation and employment. In imperfectly competitive labour markets higher labour taxes – income and payroll taxes – will increase labour costs and have negative effects on employment. Tax progression tends to moderate wages and boost employment. Moreover, if labour tax bases are unequal due to tax exemptions, the structure of labour taxation matters so that the tax wedge may not be a sufficient statistic to describe the channel of influence of labour taxation. Finally, distortionary effects of labour taxes in more corporatist economies should be smaller than in economies with more decentralised wage bargaining. Empirical evidence – though not always very strong – supports these notions.union bargaining; labour taxation; tax progression
Firm Size and Monetary Policy Transmission – Evidence from German Business Survey Data
Full text linkUsing business survey data on German manufacturing firms, this paper provides tests for hypotheses formulated in capital market imperfection theories that predict distributional effects in the transmission of monetary policy. The business conditions of small firms are found to be somewhat more sensitive to monetary policy shocks than those of large firms, also when accounting for demand differences. These effects are reinforced in business cycle downturns.monetary policy transmission, firm size, Markov switching
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
