Seminario 18/24: Vita Zhukova (UCAM) – The Role of Firms’ Trustworthiness in Business Angels’ Investment. Experimental Evidence from 3-player Trust Game

business-camera-coffee-1509428

Business Angels are private individuals who invest their personal financial resources in new and growing small firms. To study Business Angels’decisions we design an experiment based on the Trust Game (Berg et al., 1995) and add a third party, the Business Angel, who decides whether and how much to invest in a firm that is…

Seminario 18/25: Francisco Marcellán (Universidad Carlos III) A friendly approach to orthogonal polynomials and their applications

Ortogonal Polynomials

The theory of orthogonal polynomials constitutes a nice example of the interplay between classical analysis, numerical analysis, linear algebra, probability theory and mathematical physics. In this talk we will deal with orthogonal polynomials associated with measures supported on the real line with a special emphasis on the situations where they are eigenfunctions of higher order…

Seminario18/23: Francisco Martínez-Sánchez (U. Murcia) – Avoiding Commercial Piracy when Consumers are Loss Averse

Piracy

Abstract: I analyze how the loss aversion of consumers affects the strategies of the government and the incumbent to avoid commercial piracy and the price competition between the incumbent and the pirate. To that end, I develop a sequential duopoly model of vertical product differentiation with price competition in which consumers have a reference-dependent utility….

Seminario 18/22: Jesús Fernando López Fidalgo, Universidad de Navarra. Bayesian Optimal Experimental Design

bayesian-2889576_1280

El diseño experimental es la única situación en la que es significativo dentro de la teoría Bayesiana promediar sobre el espacio muestral. Como la muestra aún no se ha observado, se aplica el principio general de promediar sobre lo desconocido. Este marco justifica muchos criterios de optimalidad y abre nuevas posibilidades, por lo que varios…

Seminario: Luis Aguiar (JRC) – Platforms, Promotion, and Product Discovery: Evidence from Spotify Playlists

Abstract: Digitization has vastly increased the amount of new music produced and, because of streaming, has raised the number of songs available directly to consumers. While enhanced availability has levelled the playing field between already-prominent and new artists, creators may now be highly dependent on platform decisions about which songs and artist to promote. With…

Seminario 18/21: Allan Seheult, Mathematical Sciences, The University, Durham, England. Bayesian Method of Moments (BMOM) Analysis of Mean and Regression Models

bayesian-2889576_1280

A Bayesian method of moments/instrumental variable (BMOM/IV) approach is developed and applied in the analysis of the important mean and multiple regression models. Given a single set of data, it is shown how to obtain posterior and predictive moments without the use of likelihood functions, prior densities and Bayes’ Theorem. The posterior and predictive moments,…

Seminario 18/20: Ana B. Ania-Martínez (U. of Vienna) – Laboratory federalism with public funds sharing

Cover-banner-Michael

Abstract: We explore the role of public funds sharing in the  framework of laboratory federalism, viewed as a learning process of policy innovation and imitation. In a model of decentralized, rich-to-poor redistribution with labor mobility, such a learning dynamics leads to the complete erosion of the welfare state. We show that suitably designed funds sharing schemes can correct this…

Seminario 18/19: Lorenzo Ductor (Middlesex University) – Connections to Decision Makers: evidence from economics editors

Magnifying lens  on the background of the stack of magazines

Abstract: Are connections to decision makers valuable? Do connections lead to better or worse decisions? And if they do, why is that? We set out to answer these questions by studying connections to the editorial board members of more than 100 economics and finance journals over the period 1990-2011. Departments double their publications in a journal when…

Seminario 18/18: Iñaki Permanyer (Centre d’Estudis Demogràphics, Barcelona)- Measuring poverty in multidimensional contexts

beggar-begging-homeless-2128

Abstract: When measuring multidimensional poverty it is reasonable to expect that the trade-offs between variable pairs can differ depending on whether the concerned pairs are complements or substitutes. Yet, currently existing approaches based on deprivation count distributions unrealistically assume that all pairs of variables are related in the same way, an unfortunate circumstance that undermines…

Seminario 18/17: Ricardo Martínez (Universidad de Granada) THE PROBLEM OF DIVIDING A BUDGET AMONG SEVERAL DISTRICTS

Budget

We study the problem of dividing a budget among the districts of a city taking into account their population and wealth. We focus on order preservation properties that ensure higher transfers to those districts with larger populations and, at the same time, introduce a policy redistribution so that districts with lower wealth per capita obtain…
