In this paper we present a Stackelberg differential game to study the dynamic interaction between a polluting firm and a regulator who sets pollution limits overtime. At each time, the firm settles emissions taking into account the fine for non-compliance, and balances current costs of...

Global warming, intermittent production, and efficient use of energy require adequate demand response policies. The price inelasticity of electricity demand represents the main obstacle for developing adequate measures. A potential source of demand inelasticity is the temperature effect ‐the...

Using data from a Spanish assessment program of fourth-grade pupils, we analyze to what extent using certain teaching practices and materials in class is related to achievement in maths and reading. We distinguish using traditional and modern teaching styles. As a novelty, we measure in-class...

This paper uses data from the 2002-2005-2008 waves of the Spanish Survey of Household Finances (EFF) to investigate whether debts burdens hamper people's health. Several measures of debt strain are constructed, including debt-to-income ratios, the existence of debt arrears and amounts of...

Recent research has determined the existence of a border effect on trade flows within a country associated to agglomeration economies, the size of the spatial unit of reference, as well as to alternative measures of transport costs. Using a micro-database on road freight shipments within Spain...

We discuss how to properly decompose economic efficiency when the underlying technology is non-homothetic using alternative allocative and technical efficiency criteria. We first show that only under the production of one output and assuming the particular case of constant returns to scale...

An article in Science (4 November 1960) proposed Friday 13 November AD 2026 as the "Doomsday" of planet Earth, a doomsday produced by the "world population" going to infinity. In that paper, a rudimentary rate equation describing the evolution of the world population with time, was approximated...

The interactive implementation of agents’ intentional actions generates new combinations that are at the base of structural change and complexity and produce unexpected consequences. An interesting case of study is provided by the absorption of new technology strategies for development. A...

Between 1949 and 1989, communism restricted private entrepreneurship in East Germany, but even after reunification in 1990 entrepreneurship remained low compared to other transition economies. To quantify the determinants of low entrepreneurship in East Germany and its impact on economic...

Cost or revenue efficiency measurement based on the approach initiated by Farrell has received great attention from academics and practitioners since the fifties. Farrell’s approach decomposes cost efficiency into two different sources, viz. technical efficiency and allocative efficiency....
