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....

We analyze the strategic decision of firms to voluntarily certify corporate social responsibility (CSR) practices in a context where other firms can falsely pretend to be socially responsible. Equilibrium outcomes are crucially determined by consumers' beliefs about the credibility of firms' CSR...

We analyze the impact of increasing longevity on technological progress within an R&D-based endogenous growth framework and test the model's implications on OECD data from 1960 to 2011. The central hypothesis derived in the theoretical part is that - by raising the incentives of households to...

After the seminal paper by McCallum, various authors have estimated the effect of regional and national borders on trade. This paper digs deeper into the matter, estimating how the internal and external border effect is affected by the non-linear relation between trade and distance at different...

As recession and financial crisis spread across Europe an increasing number of people are at risk of poverty and social exclusion. Children are more exposed to the risk of poverty and social exclusion than the overall population of the EU. The current climate of economic downturn calls out for...

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...
