While the crisis proceeds: A world redistribution of economic power?

The crisis has drawn attention to the fact that not only emerging powers but other regions of the world as well may be offering different development models and may constitute into alternative, in some dimensions more positive agents, in the conduct of the present stage of globalisation. Notwithstanding, the traditional western powers have not lost a large amount of control of the world economy. And the crisis proceeds, reallocating world power as in a Hobbesian anarchy. It is difficult to foresee smooth developments in the near future. On the contrary, multilateralism seems to be losing ground to unilateral action or bilateral arrangements. More or less disguised currency wars may lead to serious disequilibria, and turf wars may become more frequent, with motives ranging from securing captive markets to control of specific commodities and energy goods, or targeted regulatory frameworks. As economic policy becomes even more involved with defence and security affairs, the feedbacks from each side to the other seem likely to keep dissent and animosity high, rather than contributing to peaceful and constructive approaches. A more trouble-prone world may be easily expected.

Aux archives de l'animisme. Ethnographie et théorie de la "religion sauvage" chez Edward Tylor

En 1871, Edward Tylor rejeta fermement les récits de son temps qui niaient l'existence de croyances religieuses chez certains peuples alors considérés comme sauvages. C'était le cas, tout particulièrement, de l'explorateur victorien Samuel Baker, dont l'autorité ethnographique fut mise en cause à travers la citation de quelques voyageurs étrangers, dont deux français, qui avaient également observé les peuples nilotiques. Contrairement à d'autres sources de Primitive Culture, la qualité de ces ethnographies oubliées était, hélas, tout à fait médiocre ; mais elles permirent à Tylor de faire l'une des affirmations les plus décisives de son œuvre, celle de l'universalité de l'animisme. Ce passage capital - concernant des peuples qui deviendront célèbres dans l'histoire de l'anthropologie, à commencer par les Nuer - recèle par ailleurs une dimension additionnelle. Tylor voulait élargir à tout être spirituel les critères d'identification d'une religion, sauf que les ethnographes du Nil Blanc suggéraient que ces rudes populations croyaient bel et bien en un être suprême. Le dossier du monothéisme était comme anticipé par la force de ces données ; mais il ne faut pas y voir une contradiction de la part de Tylor. Au contraire, cette dialectique imprévue entre l'ethnographie et la théorie permet de mieux saisir la portée du concept d'animisme dont il fut le créateur.

Who owns the largest firms around the world?

In this research paper we evaluate how corporate control around the world is defined and which variables, related to a firm's characteristics and the countries' infrastructures, influences this. We find that there is a small number of countries where firms are widely held. The role of financial institutions seems to be different in civil and common law-based countries. While they seem to act as a monitor of management in common law-based countries, in civil law countries they act as a monitor of large shareholders. Finally, we find that firm's size is the most important determinant of ultimate owners.

The flow-performance relationship around the world

We use a new dataset to study how mutual fund flows depend on past performance across 28 countries. We show that there are marked differences in the flow-performance relationship across countries, suggesting that US findings concerning its shape do not apply universally. We find that mutual fund investors sell losers more and buy winners less in more developed countries. This is because investors in more developed countries are more sophisticated and face lower costs of participating in the mutual fund industry. Higher country-level convexity is positively associated with higher levels of risk taking by fund managers.

Analysis of world economic variables using multidimensional scaling

Waves of globalization reflect the historical technical progress and modern economic growth. The dynamics of this process are here approached using the multidimensional scaling (MDS) methodology to analyze the evolution of GDP per capita, international trade openness, life expectancy, and education tertiary enrollment in 14 countries. MDS provides the appropriate theoretical concepts and the exact mathematical tools to describe the joint evolution of these indicators of economic growth, globalization, welfare and human development of the world economy from 1977 up to 2012. The polarization dance of countries enlightens the convergence paths, potential warfare and present-day rivalries in the global geopolitical scene.
