We sketch a visionary strategy for Europe in which full employment is quickly regained by 2020, income inequality is reduced and the economies are more sustainable. We call this scenario "vibrant". It is contrasted with what would happen if present policies continue within the European Union...

Taxation under oligopoly is analysed in a general equilibrium setting where the firms are large relative to the size of the economy and maximise the utility of their shareholders. It turns out that the model is an aggregative game, which simplifies the comparative statics for the effects of...

Using perfectly competitive, general equilibrium models of international trade, specific import tariffs, specific export taxes, and ad valorem trade taxes are compared in a trade war. A trade war is modelled as a NE in trade policies, where each country can choose to use ad valorem trade taxes...

This paper characterizes the out-of-equilibrium dynamics of a symmetric, pure exchange economy with two goods and N agents with uniformly distributed preferences and identical endowments. Relaxing the auctioneer assumption, but maintaining a global price rule, sequentially random pairwise...

Following the paradigm of neoclassical economics, the price mechanism is often considered as the unique efficient vehicle for driving the free markets; therefore, there is no any position for the government's role in an Arrow-Debreu's economy. However, there is no real evidence to support that...

An economy with ex ante markets for future delivery contingent on ex post spot market prices is considered. Since spot prices are publicly observed ex post, this framework bypasses the enforcement problems that may arise as a result of differential information about states of nature....

The notion of uncertain delivery is extended to study exchange economies in which agents have different abilities to distinguish between goods (for example a car in good condition versus a car in bad condition). In this setting, it is useful to distinguish goods not only by their physical...

Succeeding Dutta, Sen and Vohra (1995) and Saijo, Tatamitani and Yamato (1997), we define two types of natural mechanisms quantity and price-quantity types, in convex production economies, and characterize the class of Pareto subsolutions doubly implementable in Nash and strong Nash equilibria...
