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 ...
