Seminario 22/09 – Debrah Meloso (Toulouse Business School) Algorithm choice in experimental markets: individual and aggregate effects

images

We use high-performance Continuous Double Auction trading software and algorithms to study the effects of algorithmic trading on pricing and allocative efficiency in a laboratory environment. In addition to trading manually, participants can deploy algorithms that bid marginal valuations modulo a spread and a market-making (maker) or liquidity-taking (taker) parameter. The spread and maker/taker parameters…

Seminario 22/08: Agustí Segarra Blasco (Universitat Rovira i Virgili). Investigar y divulgar: ¿dos caras de la misma moneda?

divulgacion

La investigación científica y la divulgación, esto es poner al alcance de un público más amplio son dos caras de una misma moneda, pero no es lo mismo. Entre los científicos y también entre los economistas encontramos a grandes investigadores que con el paso de los años también se han convertido en divulgadores muy populares…

Seminario 22/04: Concepción González García (UCAM): Fiscal Consolidation in Heavily Indebted Economies

Public debt

In this paper, I build a dynamic general equilibrium model calibrated to the U.S. economy to study the macroeconomic effects of alternative fiscal consolidation strategies in a context where the private sector is heavily indebted. Fiscal consolidation is defined as a permanent reduction of the public debt-to-GDP ratio by means of government spending cuts or…

Seminario 20/15:Marco A. López (Universidad de Alicante): El impacto social de la Matemáticas

Matemáticas_primaria

En esta presentación se analizan las diferentes razones que contribuyen a que las Matemáticas se encuentren, hoy en día, en un primer plano de actualidad. Destacaríamos, en primer lugar, su presencia, como lenguaje y herramienta fundamental, en todas las ciencias (incluidas las sociales) y ramas de la tecnología. Nos detendremos en temas específicos en los…

Seminario 20/09: Alfonso Rosa (UM): Preventing (panic) bank runs.

bank run

We  study experimentally how to prevent bank runs using a mechanism inspired in Andolfatto et al. (2017). They propose a mechanism that eliminates bank runs as an equilibrium situation of the deposit contract and implements uniquely the efficient outcome. In our experimental enviroment bank runs may emerge both as a coordination failure in equilibrium and…

Seminario 18/11: Jesús Vázquez (U. País Vasco)-The bond term premium in an estimated DSGE model with real-time learning

bond-market-inflation

ABSTRACT: Adaptive learning (AL) takes over other features needed to generate a sizable term premium under rational expectations. Indeed, a time-varying term premium emerges in a first-order approximation of a DSGE model under AL. We estimate a real-time AL model that builds on Slobodyan and Wouters (2012a). Our extension disentangles the expectations hypothesis of the term structure (EH)…

Seminario 17/07: Mª José Gutierrez (U. País Vasco) – Harvesting Control Rules that deal with Scientific Uncertainty

uncertainty

Abstract: By using robustness methods we design HCRs that explicitly include scientific uncertainty. Under scientific uncertainty –when the perceived model can be generated by a nearby operating model– robust HCRs are designed assuming that the (inferred) operating model is more persistent than the perceived model. As a result, a robust HCR has a steeper ratio…

Seminario 17/06: – Carlos Escudero (U. Autónoma de Madrid) – Sobre negociar con información privilegiada y ecuaciones diferenciales estocásticas

inversion2-450×290

Abstract Un problema clásico en el campo de la matemática financiera es el encontrar carteras de inversiones óptimas en el caso de que varias inversiones sean posibles. Si el inversor tiene información privilegiada, al menos dos cosas mejoran. La primera, obviamente, sus probabilidades de obtener beneficio. La segunda, el perfil de las matemáticas necesarias para…

Seminario 15/09: T. Ñíguez Grau (U. Westminster) – The expansion of moments density

HamburgerDensity4

Abstract This paper introduces a novel semi-nonparametric (SNP) distribution that we name Expansion of Moments (ME hereafter). The innovation of this density lies in its polynomials given by the difference between the n-th power of the variable and the n-th moment of the parametric density used as basis. We show that the ME keeps the…
