A través del presente trabajo de investigación, buscamos sustentar la deseabilidad, viabilidad y rentabilidad del Modelo de Negocio de Innobag Perú, que tiene como objetivo la distribución gratuita de bolsas de papel reciclado con publicidad impresa a bodegas, mini-markets y puestos de mercado en Lima Metropolitana. Innobag Perú busca contribuir con la reducción en el consumo de bolsas plásticas, atacando y aprovechando uno de los principales momentos de uso, generando ahorros en los establecimientos e incrementando la atractividad de nuestro producto. Completamos nuestra propuesta de valor, convirtiendo estas bolsas de papel reciclado en un medio para que las empresas anunciantes publiciten su marca de manera efectiva y directa en un momento de alto uso asegurando la viabilidad de nuestro modelo de negocio. A través de un sondeo realizado entre consumidores, administradores de bodegas, mini-markets y puesto de mercado; y decisores de inversión en publicidad de empresas anunciantes, hemos logrado validar la deseabilidad de nuestro modelo de negocio. Nuestro análisis económico financiero, nos ha permitido validar la rentabilidad del modelo, esperando un VAN de S/ 114,202 y una TIR de 81.26%. / Through this research work, we seek to support the desirability, feasibility and profitability of the Innobag Peru Business Model, which aims to distribute free recycled paper bags with printed advertising to grocery stores, mini-markets and market stalls in Lima. Innobag Peru seeks to contribute to the reduction in the consumption of plastic bags taking advantage of one of the main moments of its use, generating savings for the owners of these establishments and increasing the attractiveness of our product. We complete our value proposition by turning these recycled paper bags into a mean for companies to advertise their brand effectively and directly at a time of high use, ensuring the viability of our business model. Through our market research conducted among consumers, decision makers of investment in advertising as well as managers of grocery stores, mini-markets and market stalls, we have validated the desirability of our business model. Our financial and economic analysis allowed us to validate the profitability of the model, expecting an NPV of S / 114,202 and an IRR of 81.26%. / Trabajo de investigación

In recent decades, it was shown that belowground competition for some plants may take form of the tragedy of the commons (TOC). In these plants, the competing neighbours invest more in root systems than would be appropriate for optimal nutrient uptake for the group and also more than they do when grown alone. However, there is also strong evidence that other species do not follow TOC, and tailor their root system to best nutrient exploitation irrespectively of competitor presence. The root investment strategy of these plants should correspond to the ideal free distribution (IFD). In my thesis I focus on two aspects:  I use game theoretical models to explore, whether those strategies can coexist within species and also whether different species can coexist if they have different strategy. From this model I draw predictions, which I test by meta-analysis.  Using Agrostis stolonifera as a model, I test assumptions on nutrient and neighbour perception, which underlie TOC and IFD models. I show that according to mathematical models, those two strategies can coexist in different species in a community, but cannot coexist within a species. Within a species, the TOC strategy should always dominate, once it appears. This can be extrapolated to macroevolutionary scale - once TOC occurs in certain clade, it should...
