We build a heterogeneous-firms model with firm-specific wages and credit frictions to study the role of financial development for inequality in the global economy. If there are many small firms, better access to external funds reduces wage inequality and unemployment. In contrast, if there are...

A multi-country Schumpeterian growth model is constructed when there is world-wide externality in technological knowledge. Households can enter the labour force as workers or become engineers at some cost. Production employs both workers and engineers while R&D uses only engineers. Workers are...

Economists around the world rely in addition to official statistics on business (and consumer) surveys, which are more up-to-date. However, for many emerging and developing countries there is a lack of such surveys. This gap can, at least partly, be filled by the Ifo World Economic Survey (WES)....

Using a factor structural VAR for 14 countries out of the G20 group, we document that output innovations originating outside the G7 account for shares of 10 to almost 25 percent in the business cycle fluctuations of G7 GDP growth. Using auxiliary regressions, we additionally find that these...

We provide evidence indicating that countries with well-developed social security systems do not necessarily face a trade-off between social spending and competitiveness. On average, countries that spend a lot on social needs score well in the competitiveness league. We investigate the...

I study a model of geopolitical organization endogenizing the size of nations, of their public spending and of their degree of openness. The optimal geography may not be a stable equilibrium and the Alesina-Spolaore bias toward too many nations tends to be confirmed. However, multiple equilibria...

Modern globalization (which includes free flows of trade and factors of production across frontiers, stable rates of exchange, the containment of warfare and mercantilism, the preservation of the environment and latterly the protection of cities against rogue states and terrorism) are among the...

This paper proposes a model in which the removal of barriers to trade and factor mobility is associated with endogenous fragmentation of the value-added chain. Fragmentation is the outcome of cost competition - the profit-maximizing choice of cost structure by monopolistically competitive firms....

The traditional school of economic policy analysis predicts that globalisation will give rise to predatory competition between the governments of the European nation states. The consequence is anticipated to be a marked reduction in, if not the destruction of, the benevolent Welfare State. The...

Inequality is an important threat to the globalization of the world economy that we experience today. This contribution uses a new measure of inequality: heigth inequality. It covers not only wage recipients, but also the self-employed, the unemployed, housewifes, children, and other groups who...
