Traditional budgeting during financial crisis

[EN] This study examines the evolution of budgeting practices in the extremely difficult Spanish economic environment. In order to analyse if companies are still maintaining their budgeting process and if, right now, they are facing more difficulties in forecasting accurate indicators, two similar web surveys were addressed over two periods of time, firstly in 2008 at the beginning of the financial crisis, and secondly in 2013 after five years of a downward trend. In addition, in-depth interviews were conducted to investigate how companies brought more flexibility to their budgeting process in order to cope with environmental uncertainty. The survey indicates that 97% of respondents are still using a traditional budgeting process being this result similar to the one found in 2008. However, 2013 showed that the reliance on forecasted information is being increasingly questioned. Furthermore the study revealed that the respondents are bringing more flexibility to their processes, being able to modify the objectives once the budget is approved and to obtain new resources outside the budgeting process. This paper contributes to revealing information about difficulties in setting reliable objectives in a turbulent environment and provides data about the evolution of budgeting practices over five years during an austere economic crisis.

Endogenous fisheries management in a stochastic model: Why do fishery agencies use TAC

The aim of this paper is to explain under which circumstances using TACs as instrument to manage a fishery along with fishing periods may be interesting from a regulatory point of view. In order to do this, the deterministic analysis of Homans and Wilen (1997)and Anderson (2000) is extended to a stochastic scenario where the resource cannot be measured accurately. The resulting endogenous stochastic model is numerically solved for finding the optimal control rules in the Iberian sardine stock. Three relevant conclusions can be highligted from simulations. First, the higher the uncertainty about the state of the stock is, the lower the probability of closing the fishery is. Second, the use of TACs as management instrument in fisheries already regulated with fishing periods leads to: i) An increase of the optimal season length and harvests, especially for medium and high number of licences, ii) An improvement of the biological and economic variables when the size of the fleet is large; and iii) Eliminate the extinction risk for the resource. And third, the regulator would rather select the number of licences and do not restrict the season length.

On the Benefits of Including Age-structure in Harvest Control Rules

This paper explores the benefits of including age-structure in the control rule (HCR) when decision makers regard their (age-structured) models as approximations. We find that introducing age structure into the HCR reduces both the volatility of the spawning biomass and the yield. Although at a fairly imprecise level the benefits are lower, there are still major advantages for actual assessment precision of the case study. Moreover, we find that when age-structure is included in the HCR the relative ranking of different policies in terms of variance in biomass and yield does not differ. These results are shown both theoretically and numerically by applying the model to the Southern Hake fishery.

Sistema software para el control de producción de la unidad de rodajes

El presente proyecto consiste en el análisis y búsqueda de soluciones para el control de producción de la unidad de rodajes de la compañía CAF S.A. Para ello, se ha tenido que analizar procesos de producción, capturar requerimientos, desarrollar unas herramientas de control de producción temporales y elaborar una especificación de requisitos. Sin olvidar la gestión e interlocución con proveedores. Estas líneas de trabajo se encuentran descritas en esta memoria, junto con análisis de resultados, conclusiones y unas líneas futuras donde se seguirá trabajando.
