Espace juridique de l'artiste-interprète au sein de l'espace audiovisuel


Recueil Dalloz

2005, vol. Chronique, pp.575-579

Départements : Droit et fiscalité

L'espace audiovisuel actuel offre de multiples propositions entre reflets de la réalité et réalité reflétée. Confrontée aux évolutions du discours médiatique, la présence de l'artiste-interprète se décline au travers d'écritures audiovisuelles variées, de l'oeuvre de fiction au docu-drama, en passant par la télé-réalité et le documentaire. Or, au coeur de la polysémie de l'image, côtoyant divers protagonistes aux prérogatives aussi prégnantes que divergentes, l'acteur voit son espace tracé, son statut juridique vivifié, en un perpétuel paradoxe du comédien

Excess Price Volatility and Financial Innovation

In a three-period finite exchange economy with incomplete financial markets and retrading, we study the effects of the degree of incompleteness and of changes in the financial structure on asset price volatility. In what are essentially no aggregate risk economies, asset price volatility is a sunspot-like phenomenon. If markets are completed by financial innovation, asset price volatility reduction is generic. With aggregate risk, changes in the financial structure affect asset price volatility through a pecuniary externality. Financial innovation which decreases equilibrium price volatility can be crafted under conditions of sufficient market incompleteness. Numerical examples illustrate the role of risk aversion for volatility changes and show that, with or without aggregate risk, reducing the degree of incompleteness per se is not necessarily associated with a volatility reduction

Exploring Repeat Exposure Effects of Internet Advertising

In this paper, we exposure the repeat exposure effect of Internet advertising. By using a field data set of 34 advertising campaigns, we analyze functional forms of the repeat exposure effect of Internet advertising. Among four ad effectiveness measures including aided brand awareness, message recall, brand opinion (favorability), and purchase intent, only message recall shows substantial differences between control and exposures groups. Two patterns of repeating exposure effect on message recall are found: the one in monotonically increasing with a decreasing rate and the other in a quadratic form of inverted 'U'-shape with 'wearout' effect

Fiscal policy and economic growth: The role of financial intermediation


Review of International Economics

août 2005, vol. 13, n°3, pp.612-629

Départements : Finance

This paper analyzes the impact of public debt on financial efficiency in an overlapping-generations model. We argue that public debt may reduce intermediation costs by increasing the collateral of entrepreneurs. This effect is stronger, the stronger the non-Ricardian component of public debt, i.e. the more it is associated with intergenerational redistribution. This effect can be interpreted as future generations acting as a guarantee for the loans provided to the entrepreneurs of the current generation. Furthermore, multiple growth paths may arise as low taxes increase private collateral, which in turn boosts growth via financial efficiency, while higher growth allows to maintain the same debt/GDP ratio with reduced taxes

This paper outlines the conditions under which trade is beneficial for a developing country's growth. A developing country suffers from two disadvantages: low income and a comparative disadvantage in the production of modern manufactured goodsgoods which allow a high rate of human capital accumulation through learning by doing. Low income together with Engel's law imply that developing countries consume and produce very few modern goods in autarky and hence grow slowly. With international fragmentation of production, a developing country may find comparative advantage in the production of some stages of modern goods despite an absence of comparative advantage in the production of modern goods under "100% local content." More resources can then be allocated to the modern goods sector leading to greater learning externalities and hence growth under free trade than in autarky
