With the aim to explain the explosive growth of trade between China and Africa, especially the impacts of China's exportation on African countries, a simple South-South trade model is constructed to formulate the idea that for a technologically backward country to improve its production...

This paper sheds light on the restrictive nature of rules of origin (ROO) and on the role of diagonal cumulation in mitigating the protectionist content of ROO. Empirical evidence suggests that diagonal cumulation has beneficial effects on trade - particularly among spoke countries. We show that...

Conventional normative economics is built on the assumption that people act as if seeking to satisfy coherent and a priori preferences. This model has however been challenged by many empirical works highlighting the existence of systematic deviations from the behaviour predicted by the...

The "Elimination by aspects" (EBA) duopoly of product differentiation (Laurent, 2006a) was constructed from the discrete model of probabilistic choice worked out by Tversky (1972a,b). In this framework, an unique price equilibrium exists with a "differentiation by attributes", which embodies...

European countries have increased their use of environmental tax instruments by designing new tax bases. But, many countries have to face the opposition of the public opinion, for fear of the distributive consequences of these environmental tax reforms. This paper sheds light on the distributive...
