The role of oblivion, memory size and spatial separation in dynamic language games

In this paper we present some multiagent simulations in which the individuals try to reach a uniform vocabulary to name spatial movements. Each agent has initially a random vocabulary that can be modified by means of interactions with the other agents. As the objective is to name movements, the topic of conversation is chosen by moving. Each agent can remember a finite number of words per movement, with certain strength. We show the importance of the forgetting process and memory size in these simulations, discuss the effect of the number of agents on the time to agree and present a few experiments where the evolution of vocabularies takes place in a divided range.This paper has been sponsored by the Spanish Interdepartmental Commission of Science and Technology (CICYT), project numbers TEL1999-0181, and TIC 2001-0685-C02-01

The swing of the inflation dynamics across OECD countries

Master in Economics: Empirical Applications and Policies. Academic Year 2021-2022.In recent business cycles, U.S. inflation has experienced a reduction in inflation volatility, inflation persistence and, a severe weakening of the correlation with nominal interest (Gibson's paradox). This project concludes that the empirical evidence found in the U.S. extends to other OECD countries such as Canada, Australia, the UK and France characterized by having an independent central bank. Furthermore, we examine inflation dynamics in the U.S. with a 4-equation DSGE model augmented with money. Our model qualitatively reproduces the swings in inflation statistics, but lacks sources of nominal and real rigidity to fully capture the Gibson's paradox. In spite of these model ́s limitations, we find changes in price stickiness, the monetary policy rule, and the persistence of inflationary shocks as main explanatory factors of the Gibson paradox

Novedades documentales en torno a Pablo de Céspedes. El expediente de limpieza de sangre

La biografía de Pablo de Céspedes ha permanecido por largo tiempo oculta por el velo de la ausencia documental. Por ello, el hallazgo del expediente de limpieza de sangre, trámite al que el humanista tuvo que someterse para ingresar en el cabildo cordobés, supone una importante fuente de conocimiento, sobre todo para lo relativo a su entorno familiar inmediato y su procedencia. Al mismo tiempo, permite profundizar en un interesante tema como es la carrera del prestigio del artista a través del acceso a puestos de relevancia social.Little has been known of the biography of Pablo de Céspedes. For this reason, the discovery of documents proving his purity of blood is of supreme importance. He was obliged to undergo the formality in order to enter the Chapter of the Cathedral in Córdoba. From these documents, we have been able to obtain information regarding his immediate family and his place of origin. We have also been able to discover more about his career as an artist of prestige through his access to positions of social relevance
