How Does Liquidity Affect Government Bond Yields?
The paper explores the determinants of yield differentials between sovereign bonds in the Euro area. There is a common trend in yield differentials, which is correlated with a measure of aggregate risk. In contrast, liquidity differentials display sizeable heterogeneity and no common factor. We propose a simple model with endogenous liquidity demand, where a bond’s liquidity premium depends both on its transaction cost and on investment opportunities. The model predicts that yield differentials should increase in both liquidity and risk, with an interaction term of the opposite sign. Testing these predictions on daily data, we find that the aggregate risk factor is consistently priced, liquidity differentials are priced for a subset of countries, and their interaction with the risk factor is in line with the model’s prediction and crucial to detect their effect.
On prosperity and posterity: the need for fiscal discipline in a monetary union
We show how in a Blanchard-Yaari, overlapping generations framework, perfect substitutability of government bonds in Monetary Union tempts governments to exploit the enlarged common pool of savings. In Nash equilibrium all governments increase their bond financed transfers to current generations (prosperity effect) at the expense of future generations (posterity effect). The resulting deficit bias occurs even if one assumes that before Monetary Union countries had eliminated their deficit bias by designing appropriate domestic institutions. The paper provides a rationale for an increased focus on fiscal discipline in Monetary Union, without the need to assume imperfect credibility of existing Treaty provisions or to refer to extreme situations involving sovereign default. We draw on existing empirical evidence to argue that the degree of government bond substitutability within the European Monetary Union is an order of magnitude larger than in the global economy.

The policy mix in a monetary union under alternative policy institutions and asymmetries
In this paper we study the monetary and fiscal policy making in a monetary union when authorities face asymmetries in the countries constructing this monetary union. We analyze this problem in an asymmetric environment using a two-country theoretical model and by introducing two alternative types of national asymmetries : asymmetric shocks and the asymmetric transmission mechanism. The central issue of the paper is the design of the appropriate monetary and fiscal policy institutions. In this respect, we investigate which of the two alternative types of monetary policymakers (country representatives or governors) facing to two alternative types of fiscal policy (decentralized or centralized) contributes to better resolve the problem of the trade-off between credibility and flexibility. Our results show that delegate the monetary policy to a council of union-wide governors with decentralized fiscal policies is the appropriate institutional design that would reduce the iinflation bias and stabilize better the regional idiosyncratic shocks in a monetary union in the cases of perfectly asymmetric and perfectly symmetric shocks. In addition, in the case of asymmetric transmission, the monetary union would be better off with a council of monetary policy governors and centralized fiscal policies.EMU, Policy-Mix, Asymmetric shocks, Asymmetric transmission
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Common Monetary Policy with Asymmetric Shocks
What policy objective should a common central bank in a heterogeneous monetary union pursue? Should it base its decisions on the EU-wide average of inflation and growth or should it instead focus on (appropriately weighted) national welfare losses based on national rates of inflation and growth? We find that a central bank that minimises the sum of national welfare losses reacts less to common shocks. This can lead to higher average union-wide expected welfare if the variability of common shocks is large relative to the inflation bias and if idiosyncratic demand shocks in the non-tradables sector are not too high.monetary policy, monetary union, transmission mechanism
Variations on the Author
“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
One Size Must Fit All: National Divergences in a Monetary Union. CEPS Working Documents No. 149, July 2000
What policy objective should a common central bank in a heterogeneous monetary union pursue? Should it base its decisions on the EU-wide average of inflation and growth or should it instead focus on (appropriately weighted) national welfare losses based on national rates of inflation and growth? We find that a central bank that minimises the sum of national welfare losses reacts less to common shocks and that this can lead to higher average union-wide expected welfare, if the variability of common shocks is large relative to the inflation bias. But for countries with a transmission mechanism close to the average, welfare can actually be lower in this case. The inflationary bias depends on the interaction between the transmission mechanism and distortions in labour markets
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
