A strategy-proof and budget-balanced mechanism for carbon footprint reduction by global companies

The problem addressed in this paper is concerned with an important issue faced by any green aware global company to keep its emissions within a prescribed cap. The specific problem is to allocate carbon reductions to its different divisions and supply chain partners in achieving a required target of reductions in its carbon reduction program. The problem becomes a challenging one since the divisions and supply chain partners, being autonomous, may exhibit strategic behavior. We use a standard mechanism design approach to solve this problem. While designing a mechanism for the emission reduction allocation problem, the key properties that need to be satisfied are dominant strategy incentive compatibility (DSIC) (also called strategy-proofness), strict budget balance (SBB), and allocative efficiency (AE). Mechanism design theory has shown that it is not possible to achieve the above three properties simultaneously. In the literature, a mechanism that satisfies DSIC and AE has recently been proposed in this context, keeping the budget imbalance minimal. Motivated by the observation that SBB is an important requirement, in this paper, we propose a mechanism that satisfies DSIC and SBB with slight compromise in allocative efficiency. Our experimentation with a stylized case study shows that the proposed mechanism performs satisfactorily and provides an attractive alternative mechanism for carbon footprint reduction by global companies.

Encouraging the implication of shops in the city by means of retail associationism. The case of Bilbao

[EN] Retail activity in urban areas constitutes a key variable in the health of a city. For that reason, the processes of urban revitalization and retail revitalization run in parallel manner. Integrated management models for urban centres constitute a good framework to harness the competitiveness of the cities and their retail businesses, but they require of all implied participation, by means of a public – private cooperation.

Marcas de distribuidor: análisis del espacio en el lineal por categorías y enseñas

[ES] El objetivo principal de este trabajo es confirmar si la ocupación de espacio por parte de las marcas de distribuidor en los lineales es excesivo, tal y como parecen afirmar los productores de marcas de fabricante. Para ello, se presentan los resultados de una observación del espacio ocupado por estas marcas en una muestra representativa de 40 categorías en 55 establecimientos. Con los datos obtenidos, se muestran las diferencias existentes entre categorías y entre enseñas. Además se observa si los establecimientos han llegado a un punto de lineal máximo y si el espacio ocupado por sus marcas propias es desproporcionado en relación a su cuota de mercado.
