If the Fed sneezes, who catches a cold?
No full textThis paper studies the international spillovers of US monetary policy shocks on a number of macroeconomic and financial variables in 36 advanced and emerging economies. In most countries, a surprise US monetary tightening leads to depreciation against the dollar; industrial production and real GDP fall, unemployment rises. Inflation declines especially in advanced economies. At the same time, there is significant heterogeneity across countries in the response of asset prices, and portfolio and banking cross-border flows. However, no clear-cut systematic relation emerges between country responses and likely relevant country characteristics, such as their income level, dollar exchange rate flexibility, financial openness, trade openness vs. the US, dollar exposure in foreign assets and liabilities, and incidence of commodity exports
The expected effect of the euro on the Hungarian monetary transmission
Full text linkThe most important mechanism through which monetary policy affects the real economy in Hungary is the exchange rate channel. With euro adoption, this mechanism will largely disappear and the impact of monetary policy will be transmitted via the interest rate channel, presently seen as rather weak. This has raised concerns that the influence of monetary policy on the real economy in Hungary could be very limited after euro adoption. On top of this, other concerns have been voiced as regards potential asymmetries in the wage-setting behaviour, the exchange rate and credit channels. Based on the experience of today’s euro area participating countries and the structural characteristics of the Hungarian economy, this paper argues that after euro adoption 1) we may expect a broadening of the scope of the interest rate channel of monetary policy after euro adoption, 2) there are no institutional obstacles in the way of the effective functioning of the expectations channel in Hungary 3) substantially different monetary conditions from that in the euro area as a result of a different trade orientation are unlikely, and, finally 4) some asymmetries in the balance sheet channel may continue to exist for some time between Hungary and the core euro area countries but its effect will be significantly smaller after euro zone entry.monetary transmission mechanism, transmission channels, EMU participation.
US imbalances: the role of technology and policy
Full text linkThis paper investigates the role of three likely factors in driving the steady deterioration of the US external balance: US technology developments, changes in the US government fiscal position and the Fed’s monetary policy. Estimating several Vector Autoregressions on US data over the period 1982:2 to 2005:4 we identify five structural shocks: a multi-factor productivity shock; an investment-specific technology shock; a monetary policy shock; and a fiscal revenue and spending shock. Together these shocks can account for the deterioration and subsequent reversal of the trade balance in the 1980s. Productivity improvements and fiscal and monetary policy easing also play an important role in the increase of the external deficit since 2000, but these structural shocks can not explain why the trade balance deteriorated in the second half of the 1990s.

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
