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

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 18/18: 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…

Seminario 18/14: (Greys Sosic, USC Marshall School of Business, USA) Incentives and Emission Responsibility Allocation in Supply Chains

greenhouse_gas_emissions

In view of the urgency and challenges of mitigating climate change, it should be noted that Greenhouse Gas (GHG) emitted from the supply chains of the 2,500 largest global corporations accounts for about 18% of global GHG emissions. Therefore, rationalizing emissions in supply chains could make a significant contribution to achieving the CO2 emission reduction…

Seminario 17/19: Matilde Lafuente (U. Mucia)- La dimensión trabajo en el contexto de la Exclusión Social en España

exclusion3

En el análisis de la exclusión social, se ha constatado la importancia de la dimensión trabajo. La persistencia del paro, la temporalidad en el empleo o los bajos salarios, inciden de forma importante sobre los niveles de pobreza y exclusión social. En este trabajo se ha recopilado información sobre distintas variables relacionadas con el mercado…

Seminario 17/17: Guoyin Li (U. New South Wales) – Some Recent Advances in Polynomial Optimization

OPTIMIZACION

Optimization problems involving polynomial functions are of great importance in applied mathematics and engineering, and they are intrinsically hard problems. They arise in important engineering applications such as the sensor network localization problem, and provide a rich and fruitful interaction between algebraic-geometric concepts and modern convex programming. In this talk, we will discuss some recent…

Seminario 17/11: El-Ghazali Talbi (U. Lille) – Combining metaheuristics with mathematical programming and machine learning

OptAl

Abstract During the last years, interest on hybrid metaheuristics has risen considerably in the field of optimization and machine learning. The best results found for many optimization problems in science and industry are obtained by hybrid optimization algorithms. Combinations of optimization tools such as metaheuristics, mathematical programming, constraint programming and machine learning, have provided very…

Seminario 17/09: Montserrat Viladrich (U. Lleida) – Protecting biodiversity on farm land: Which type of agri-environmental measure does it better?

farmland_3

Abstract Much biodiversity is found in farm land. However, there is usually a trade-off between farm land productivity and sustainability of natural resources.  Biodiversity conservation in agricultural land usually requires to carry on a series of conservationist practices that are costly. Therefore, farmer’s participation in conservationist programs requires economic incentives.  Our goal is to identify…

Seminario 17/08: Michel Théra (U. Limoges) – Perturbation of error bounds

bounds

Abstract In the current presentation, I intend to extend the developments in Kruger, Ngai  & Théra, SIAM J. Optim. 20(6), 3280-3296 (2010) and, more precisely, to characterize, in the Banach space setting, the stability of the local and global error bound property of inequalities determined by proper lower semicontinuous under data perturbations. I will propose…

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…
