  • Di Giovanni, Julian; Levchenko, Andrei A.; Mejean, Isabelle (American Economic Association, 2018)
    This paper investigates the role of individual firms in international business-cycle comovement using data covering the universe of French firm-level value added and international linkages over the period 1993–2007. At the ...
  • Galí, Jordi, 1961-; Monacelli, Tommaso (American Economic Association, 2016)
    We study the gains from increased wage flexibility using a small open economy model with staggered price and wage setting. Two results stand out: (i) the effectiveness of labor cost reductions as a means to stimulate ...
  • Galí, Jordi, 1961- (American Economic Association, 2018)
    In August 2007, when the first signs emerged of what would come to be the most damaging global financial crisis since the Great Depression, the New Keynesian paradigm was dominant in macroeconomics. Ten years later, tons ...
  • Nualart, Eulàlia (Institut d’Estudis Catalans, 2011)
    Durant els anys setanta, el matemàtic francès Paul Malliavin va revolucionar la teoria de les probabilitats quan va introduir el càlcul de variacions estocàstic que avui porta el seu nom. Malliavin va construir una ...
  • Kohatsu, Arturo; Nualart, Eulàlia; Tran, Ngoc Khue (Taylor & Francis (Routledge), 2017)
    In this paper, we consider a multidimensional ergodic diffusion with jumps driven by a Brownian motion and a Poisson random measure associated with a compound Poisson process, whose drift coefficient depends on an unknown ...
  • Ortún Rubio, Vicente; López-Valcárcel, Beatriz G.; Barber Pérez, Patricia; Harris, Jeffrey E. (Elsevier, 2015)
  • Baudoin, Fabrice; Nualart, Eulàlia; Ouyang, Cheng; Tindel, Samy (Institute of Mathematical Statistics (IMS), 2016)
    This article investigates several properties related to densities of solutions (Xt)t∈[0,1] to differential equations driven by a fractional Brownian motion with Hurst parameter H>1/4. We first determine conditions for ...
  • Dalang, Robert C.; Khoshnevisan, Davar; Nualart, Eulàlia; Wu, Dongsheng; Xiao, Yimin (Institute of Mathematical Statistics (IMS), 2012)
    We derive a decoupling formula for the Brownian sheet which has the following ready consequence: An N-parameter Brownian sheet in Rd has double points if and only if d<4N. In particular, in the critical case where d=4N, ...
  • Dalang, Robert C.; Khoshnevisan, Davar; Nualart, Eulàlia (Springer, 2009)
    We consider a system of d non-linear stochastic heat equations in spatial dimension 1 driven by d-dimensional space-time white noise. The non-linearities appear both as additive drift terms and as multipliers of the noise. ...
  • Khoshnevisan, Davar; Nualart, Eulàlia (International Statistical Institute, Bernoulli Society for Mathematical Statistics and Probability, 2008)
    We consider the solution {u(t, x); t≥0, x∈R} of a system of d linear stochastic wave equations driven by a d-dimensional symmetric space-time Lévy noise. We provide a necessary and sufficient condition on the characteristic ...
  • Nualart, Eulàlia; Mountford, Thomas S. (Institute of Mathematical Statistics (IMS), 2004)
    We use Girsanov's theorem to establish a conjecture of Khoshnevisan, Xiao and Zhong that ϕ(r)=rN−d/2(loglog(1r))d/2 is the exact Hausdorff measure function for the zero level set of an N-parameter d-dimensional additive ...
  • Dalang, Robert C.; Nualart, Eulàlia (Institute of Mathematical Statistics (IMS), 2004)
    We give general sufficient conditions which imply upper and lower bounds for the probability that a multiparameter process hits a given set E in terms of a capacity of E related to the process. This extends a result of ...
  • Delarue, François; Menozzi, Stéphane; Nualart, Eulàlia (Institute of Mathematical Statistics (IMS), 2015)
    In this paper we prove that the spatially homogeneous Landau equation for Maxwellian moleculescan be represented through the product of two elementary stochastic processes. The first one is the Brownian motion on the group ...
  • Eeckhout, Jan; Pinheiro, Roberto; Schmidheiny, Kurt (University of Chicago Press, 2014)
    We investigate the role of skill complementarities in production and mobility across cities. The nature of the complementarities determines the equilibrium skill distribution across cities. With extreme-skill complementarity, ...
  • Ortún Rubio, Vicente (Ministerio de Sanidad y Consumo, 2006)
    Desde que hace cinco años Vicky Zunzunegui abordara una pregunta parecida en esta sección, distintas contribuciones a la Revista han tratado el tema según muestra el índice por materias de su excelente página web. ...
  • Ortún Rubio, Vicente (Elsevier, 2006)
  • Palomo Cobos, Luis; Ortún Rubio, Vicente; Benavides, Fernando G. (Fernando García); Márquez Calderón, Soledad (Elsevier, 2006)
    El objetivo de este Informe fue repasar el impacto en la salud de las condiciones de vida anteriormente descritas, es decir los desajustes que se producen como consecuencia de la adaptación a ese entorno hostil, competitivo ...
  • Palomo Cobos, Luis; Márquez Calderón, Soledad; Ortún Rubio, Vicente; Benavides, Fernando G. (Fernando García) (Elsevier, 2006)
    A las mejoras en la salud y en la calidad y la esperanza de vida en los países desarrollados contribuyeron los avances científicos y tecnológicos, las mejoras económicas y sociales, la sociedad de la comunicación, la ...
  • Gérvas Camacho, Juan Javier; Ortún Rubio, Vicente; Palomo Cobos, Luis; Ripoll, Miguel Ángel (Ministerio de Sanidad y Consumo, 2007)
    A finales del siglo XIX empezó a separarse la gestión de la propiedad de la misma, y a principios del siglo XX empezó a ser relevante conseguir que el gestor y el trabajador hicieran lo que se esperaba de ellos (coincidir ...
  • Ortún Rubio, Vicente (Elsevier, 2007)
    La salud de los países pobres mejora aplicando conocimientos de salud pública, lo que requiere capacidad institucional y voluntad política, dos condiciones que el mero aumento de la renta no garantiza. Tanto el análisis ...
