Trade costs, trade balances and current accounts : an application of gravity to multilateral trade
Get PDFIn this paper we test the well-known hypothesis of Obstfeld and Rogoff (2000) that trade
costs are the key to explaining the so-called Feldstein-Horioka puzzle. Using a gravity
framework in an intertemporal context, we provide strong support for the hypothesis and we
reconcile our results with the so-called home bias puzzle. Interestingly, this requires a
fundamental revision of Obstfeld and Rogoff's argument. A further novelty of our work is in
tying bilateral trade behavior to desired aggregate trade balances and desired intertemporal
trade
Five minutes with Jacques Melitz: “The discontented members of the Eurozone should consider very seriously the creation of a second euro”
No full textSince the height of the Eurozone crisis, a number of reforms have been pursued to stabilise the economic situation in states using the single currency. In an interview with EUROPP’s editor Stuart Brown, Jacques Melitz outlines why the Eurozone is still suffering from two key problems – the European Central Bank’s inability to engage in proper open market operations and the lack of joint-responsibility for the banking system. He argues that, given the inflexibility of Germany, the discontented Eurozone members should give serious consideration to the possibility of creating a ‘second euro’ as an alternative
Joint estimates of automatic and discretionary fiscal policy for the OECD
Get PDFOfficial calculations of automatic stabilizers are seriously flawed since they rest on the assumption that the only element of social spending that reacts automatically to the cycle is unemployment compensation. This puts into question many estimates of discretionary fiscal policy. In response, we propose a simultaneous estimate of automatic and discretionary fiscal policy. This leads us, quite naturally, to a tripartite decomposition of the budget balance between revenues, social spending and other spending as a bare minimum. Our headline results for a panel of 20 OECD countries in 1981-2003 are .59 automatic stabilization in percentage-points of primary surplus balances. All of this stabilization remains following discretionary responses during contractions, but arguably only about 3/5 of it remains so in expansions while discretionary behavior cancels the rest. We pay a lot of attention to the impact of the Maastricht Treaty and the SGP on the EU members of our sample and to real time data.Fiscal stabilization, automatic stabilizers, discretionary policy.
Adjustment Difficulties and debt overhangs in the Eurozone periphery. CEPS Working Document No. 347, May 2011
Get PDFThis paper describes four key drivers behind the adjustment difficulties in the periphery of the eurozone:
• The adjustment will be particularly difficult for Greece and Portugal, as two relatively closed economies with low savings rates. Both of these countries combine high external debt levels with low growth rates, which suggest they are facing a solvency problem. In both countries fiscal adjustment is a necessary condition for overall sustainability, but it not sufficient by itself. A sharp cut in domestic consumption (or an unrealistically large jump in exports) is required to quickly establish external sustainability. An internal devaluation (a cut in nominal wages in the private sector) is unavoidable in the longer run. Without such this adjustment in the private sector, even continuing large-scale provision of official funding will not stave off default.
• Ireland’s problems are different. They stem from the exceptionally large losses in the Irish banks, which were taken on by the national government, leading to an explosion of government debt. However, the Irish sovereign should be solvent because the country has little net foreign debt.
• Spain faces a similar problem as Ireland, although its foreign debt is somewhat higher but its construction bubble has been less extreme. The government should thus also be solvent, although further losses in the banking system seem unavoidable.
• Italy seems to have a better starting position on almost on all accounts. But its domestic savings rate has deteriorated substantially over the last decade
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
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
