Extreme interdependence and extreme contagion between emerging markets
2007
Abstract This paper uses seemingly unrelated probit techniques to separate the transmission of a crisis due to broadly defined macroeconomic interdependence from contagion due to herding, avoiding some of the caveats of the more traditional cross-correlation approach. We find that pure contagion occurred in a limited number of country pairs generally belonging to the same region. A reduction in speculative pressure can also be identified between countries in different regional blocks. This seems to suggest that after an initial crisis episode, investors tend to discriminate on the basis of location and common macroeconomic weakness or perceived similarity.
GIS-based hedonic pricing of landscape
2009
ACL; International audience; Hedonic prices of landscape are estimated in the urban fringe of Dijon (France). Viewshed and its content as perceived at ground level are analyzed from satellite images supplemented by a digital elevation model. Landscape attributes are then fed into econometric models (based on 2,667 house sales) that allows for endogeneity, multicollinearity, and spatial correlations. Results show that when in the line of sight, trees and farmland in the immediate vicinity of houses command positive prices and roads negative prices; if out of sight, their prices are markedly lower or insignificant: the view itself matters. The layout of features in fragmented landscapes comma…
Money Doctoring After World War II: Arthur I. Bloomfield and the Federal Reserve Missions to South Korea
2009
In this paper we analyse the scientific contributions of the New York Fed economist Arthur I. Bloomfield. A Canadian born economist, in 1941 Bloomfield took his PhD in economics at the University of Chicago, under the supervision of Jacob Viner and then joined the staff of the Federal Reserve Bank of New York as a Research Economist and stayed there until 1958. In this position, Bloomfield combined scholarly research on recent economic history and international financial and banking problems with active service as a member of various committees and commissions, both in the United States and abroad. While on leave from the Fed, he accepted appointments as a consultant and advisor to various …
La factibilidad de los derechos sociales en Europa: debate actual y perspectivas
2021
El presente trabajo reflexiona acerca de la relación entre el análisis económico y la efectividad y justiciabilidad de los derechos sociales en Europa. En efecto, si en la era de la globalización se confiere una posición relevante al mercado cuando se redactan las normas nacionales e internacionales sobre derechos sociales (incluso en la fase inicial –previendo el impacto económico de dichas normas, la denominada “factibilidad”), el autor pone de relieve que la estructura jurídica y dogmática de tales derechos sociales es tan idónea como la de los derechos civiles a la hora de garantizar su justiciabilidad. En tal sentido, se subraya el camino hacia un estándar común europeo en materia de d…
On the Consistent Use of VaR in Portfolio Performance Evaluation: A Cautionary Note
2010
The portfolio performance measures based on the Value at Risk (VaR) concept have gained widespread popularity and are often used in empirical studies. In the majority of empirical studies, however, a VaR-based performance measure is inconsistently used. In this article, Zakamouline emphasizes how to consistently use VaR in portfolio performance evaluation. He also elaborates on a simple framework that allows the derivation of a general formula for a portfolio performance measure that is not limited to the use of VaR-based reward and risk measures, but is valid for all reward and risk measures that satisfy a few plausible properties.
La economía social y solidaria en Grecia
2017
El 31 de octubre de 2016 el Parlamento griego aprobó la Ley 4430/2016 de Economía Social y Solidaria (ESS) con el propósito de difundir esta forma alternativa de organización de la actividad económica; apoyar y fortalecer proyectos productivos autogestionarios y de emprendimiento social colectivo, y regular las Empresas Sociales Cooperativas y las Cooperativas de Trabajadores. En este trabajo hemos analizado las principales características de la ESS griega, principalmente en relación con otros modelos europeos; y los distintos tipos de empresas que integra, subrayando las diferencias entre ellas y sus principales características frente a otras instituciones próximas como las cooperativas so…
Regulation of Investments in Infrastructure: The Interplay between Strategic Behaviors and Initial Endowments
2012
This paper explores the dynamic properties of price-based policies in a model of competition between two jurisdictions. Jurisdictions invest over time in infrastructure to increase the quality of the environment, a global public good. They are identical in all respects but one: initial stocks of infrastructure. This is a dynamic type of heterogeneity that disappears in the long run. Therefore, at the steady state, usual intuitions from static settings apply: identical jurisdictions inefficiently underinvest, calling for public subsidies. In the short run, however, counterintuitive properties are established: (i) the evolution of capital stocks can be nonmonotonic and (ii) one jurisdiction c…
DOES REAL INTEREST RATE PARITY HOLD FOR OECD COUNTRIES? NEW EVIDENCE USING PANEL STATIONARITY TESTS WITH CROSS-SECTION DEPENDENCE AND STRUCTURAL BREA…
2010
This paper tests for real interest rate parity (RIRP) among the 17 major Organisation for Economic Cooperation and Development countries over the period 1978:Q1–2006:Q1. The econometric methods applied consist of combining the use of panel data tests that are valid under cross-section dependence and the presence of multiple structural breaks. This feature is important because the misspecification errors due to not accounting for structural breaks and/or cross-section dependence can lead to misleading conclusions. Our results support the fulfilment of the weak version of the RIRP for short-term interest rate differentials once dependence and structural breaks are considered.
"Facta non verba" : an experiment on pledging and giving
2015
International audience; We design an experiment to investigate whether asking people to state how much they will donate to a charity (i.e., to pledge) increases their actual donation. Individuals’ endowment is either certain or a random variable. We study different types of pledges, namely, private, public and irrevocable, which differ in terms of the cost to the individual for not keeping the promise. We show that in absence of endowment uncertainty, private and public pledges are associated with lower donations as compared to donations in the no-pledge case: private pledges slightly reduce donations and public pledges reduce them more significantly. Donations increase with uncertainty (in…
Job Quality in the Economy for the Common Good : conceptualisation and implementation in Austria and Germany
2020
The Economy for the Common Good (ECG) is an Austrian-born movement promoting an alternative economic model built on values oriented to the common welfare such as human dignity, solidarity, ecological sustainability, social justice, transparency and democratic participation. To provide (high) quality of work plays an important role in the ECG philosophy but little is known on the actual labour conditions of workers employed in such type of firms and whether they differ from those of firms in the ?regular? default economy. In this paper we focus on Austria and Germany, the countries where this economic model is most widespread, and present results on the general structure of firms following t…
