This microeconomics text presents the traditional economic theories about utility and production, as well as the main alternative theories of consumer and company behaviour. It contains new theoretical functions created from specific optimisation procedures. Moreover, it details clearly the common function expression forms such as Cobb-Douglas and CES in which the theory is checked. Furthermore, it presents empirical tests and their interpretation in relation to the theory. Finally, the last chapter looks at choice made under conditions of uncertainty

In this book the reader is provided with an overview of the most interesting ideas in Competitive General Equilibrium Theory as well as Welfare Economy. In doing so, the author adopts a methodological approach of a closed and inter-related system where all variables are simultaneously determined. By using theorems of fixed point, revealed preference and local and global stability, the author proves the existence of unicity and stability. Furthermore, he analyses those situations where the competitive system does not allocate resources efficiently. In this sense, he examines allocation problems in regard to property rights, information problems and choice and negotiation problems. Finally, the text includes a chapter that presents a topical guide of questions related to Social Choice

El objetivo de este estudio es analizar la industria del transporte aéreo en España. Este trabajo se ha centrado en el segmento de negocio y presentamos un modelo teórico de competencia oligopolística que puede ser empíricamente probado a través de tres ecuaciones: de demanda, de cuota de mercado y de precio. Contribuimos a desarrollar la creatividad y la innovación con la elaboración de una muestra que estudia 113 rutas durante 96 quincenas (2011-2015), donde se analiza cómo reaccionan los clientes tanto a los cambios estratégicos realizados por las líneas aéreas (frecuencias, capacidad, precios) como a cambios socio-económicos. El análisis se realiza aplicando la técnica econométrica de las variables instrumentales y los resultados muestran que la competencia en este mercado se produce a la Cournot.

In the current economical and financial crisis, the economic evaluation of transport infrastructure investment projects is of most importance. Given the need of most governments to reduce spending and control the deficit, having tools that facilitate decision-making seems to be a key objective. This paper examines several high speed lines in Spain, by using the benefit-cost analysis (BCA), in order to obtain more information and determine the social costs and benefits linked to each project. Such analysis allows determining whether costs are higher than benefits, so the net social benefit is positive. Similarly, an Internal Rate of Return (IRR) per project is determined, in order to classify investments with positive BCA.

This paper analyses the determinants of knowledge in the European Union of the 27, through estimates of transcendental logarithmic production functions (translog) in different scenarios. For this, a data panel for the period 2003-2010 has been elaborated, selecting the production stochastic frontier as the most reliable model to estimate technical efficiency for European innovation. The empirical result is that technological capital, human capital and relational capital have a positive and significant influence on the generation of knowledge. Also, from the observation of results we can assure that the size (in terms of population) of a country within the EU-27 does not positively influence the technical efficiency of knowledge production.This is an empirical study about the relationship between the determinants of knowledge and the technical efficiency of the generation of knowledge, and such a study does not exist in literature for the EU-27 in the period analysed.

The objective of the present paper is to assess the railway investment project in Spain for the Santander-Madrid route, using the Cost-Benefit Analysis method. The paper aims at answering the following question - what is more viable: a High Speed Train for passengers between Santander and Madrid, or rather a High Performance Train for passengers and cargo between Santander and Madrid? Being able to answer this question is clearly key information for investment decision making in the field of government's or country's transport policy. In this study, a Cost-Benefit Analysis with two options for the railway project has been calculated: only passengers and combined passengers-cargo. In this case, results favour the passengers-cargo option rather than its alternative.
