Un año de medición del índice de Demanda Laboral: situación actual y perspectivas
(Universidad Torcuato Di Tella. Escuela de Negocios. Centro de Investigaciones en Finanzas (CIF), 2003)
El índice de demanda laboral es elaborado por la Universidad Torcuato Di Tella desde agosto de 2002. La motivación para la elaboración del índice fue la falta de un indicador mensual que reflejara la situación del ...
Delays without mistakes : response time and error distributions in dual-task
(2008-09-12)
Background: When two tasks are presented within a short interval, a delay in the execution of the second task has been systematically observed. Psychological theorizing has argued that while sensory and motor operations ...
Defaults in the 90's: Factbook and preliminary lessons
(Universidad Torcuato Di Tella. Escuela de Negocios. Centro de Investigaciones en Finanzas (CIF), 2002)
Since the Tequila crisis in 1994, and particularly after the succession of crises in Asia and the default episode in Russia, questions related to international sovereign bond restructuring have been increasingly at the ...
Liquidity protection versus Moral Hazard: the role of the IMF
(Universidad Torcuato Di Tella. Escuela de Negocios. Centro de Investigaciones en Finanzas (CIF), 2003)
This paper develops a simple game between the IMF a county and a set of atomistic private investors. The model is motivated by the case of Argentina. Under reasonable assumptions, the one shot game has no Nash equilibrium ...
Dynamics of the central bottleneck : dual-task and task uncertainty
(2006-06-27)
Why is the human brain fundamentally limited when attempting to execute two tasks at the same time or in close succession? Two classical paradigms, psychological refractory period (PRP) and task switching, have independently ...
Serial, parallel and hierarchical decision making in primates
(2017-06-26)
he study of decision-making has mainly focused on isolated decisions where choices are associated with motor actions. However, problem-solving often involves considering a hierarchy of sub-decisions. In a recent study ...
A new test for the success of inflation targeting
(Universidad Torcuato Di Tella. Escuela de Negocios. Centro de Investigaciones en Finanzas (CIF), 2003)
We propose a new test, derived from a set of variance decompositions of a structural VAR, for the success of inflation targeting. In contrast to standard sacrifice ratios this test considers changes in the structure of ...
Assessing the Impact of Contextual Information in Hate Speech Detection
(2023)
Social networks and other digital media deal with huge amounts of user-generated contents
where hate speech has become a problematic more and more relevant. A great effort has been made to
develop automatic tools for its ...
Facet-generating procedures for the maximum-impact coloring polytope
(2023)
Given two graphs G = (V, EG) and H = (V, EH) over the same set of vertices
and given a set of colors C, the impact on H of a coloring c : V → C of G,
denoted I(c), is the number of edges ij ∈ EH such that c(i) = c(j). ...
The maximum 2D subarray polytope: facet-inducing inequalities and polyhedral computations
(2022)
Given a matrix with real-valued entries, the maximum 2D subarray problem
consists in finding a rectangular submatrix with consecutive rows and columns
maximizing the sum of its entries. In this work we start a polyhedral ...
