Le marché de l'art et le trafic illicite des biens culturels : une étude de cas : la collection Barbier-Mueller.

En mars 2013, trois cent treize artefacts précolombiens, exposés auparavant dans le musée barcelonais des Suisses Jean-Paul Barbier et Monique Mueller, furent mis en vente chez Sotheby’s à Paris par ce couple de collectionneurs. L’affaire fut l’objet une couverture médiatique internationale lorsque des pays d’Amérique centrale et d’Amérique du Sud, notamment le Pérou, le Mexique et le Guatemala, protestèrent contre la tenue de cette vente, avançant que leur patrimoine culturel national n’est pas à vendre. La question centrale de ce mémoire porte sur le trafic illicite des biens culturels et elle se décline en trois axes, à partir d’une étude de cas : la collection Barbier-Mueller. Les relations complexes entre les musées et les grands collectionneurs sont observées dans le premier chapitre à la lumière des règles déontologiques qui régissent habituellement les institutions, afin de ne pas encourager l’acquisition d’objets impliqués dans des transactions illicites. Dans un deuxième temps, au moyen d’une succincte présentation du marché actuel de l’art mondial, l’influence des maisons de ventes aux enchères sera examinée. Tandis que la provenance des artefacts en vente n’est pas toujours clairement affichée, il est difficile de retracer la lignée des propriétaires ou leur nation d’origine. Or, sachant que la commercialisation illicite des biens culturels se développe à l’intérieur même du marché de l'art régulier, les auteurs parlent alors d’un « marché gris ». Ce mémoire remonte, depuis l’excavation en passant par leur exportation illégale, la chaîne de transactions de ces biens culturels qui aboutissent dans les expositions des plus prestigieuses institutions. Cette recherche aborde en dernier lieu certaines incongruités du marché de l’art en auscultant les particularités des outils fournis par l’UNESCO et l’ICOM, ainsi que la question de l’aliénation, en plus de celle des limites juridiques des pays requérants. Finalement, cette étude présente les oppositions entre le discours officiel et les actions réellement entreprises pour la protection du patrimoine culturel.

Trade Liberalization and the Profitability of Domestic Mergers.

It is often thought that a tariff reduction, by opening up the domestic market to foreign firms, should lessen the need for a policy aimed at discouraging domestic mergers. This implicitly assumes that the tariff in question is sufficiently high to prevent foreign firms from selling in the domestic market. However, not all tariffs are prohibitive, so that foreign firms may be present in the domestic market before it is abolished. Furthermore, even if the tariff is prohibitive, a merger of domestic firms may render it nonprohibitive, thus inviting foreign firms to penetrate the domestic market. In this paper, we show, using a simple example, that in the latter two cases, abolishing the tariff may in fact make the domestic merger more profitable. Hence, trade liberalization will not necessarily reduce the profitability of domestic mergers.

Semi-Parametric Weak Instrument Regressions with an Application to the Risk-Return Trade-off

Recent work shows that a low correlation between the instruments and the included variables leads to serious inference problems. We extend the local-to-zero analysis of models with weak instruments to models with estimated instruments and regressors and with higher-order dependence between instruments and disturbances. This makes this framework applicable to linear models with expectation variables that are estimated non-parametrically. Two examples of such models are the risk-return trade-off in finance and the impact of inflation uncertainty on real economic activity. Results show that inference based on Lagrange Multiplier (LM) tests is more robust to weak instruments than Wald-based inference. Using LM confidence intervals leads us to conclude that no statistically significant risk premium is present in returns on the S&P 500 index, excess holding yields between 6-month and 3-month Treasury bills, or in yen-dollar spot returns.

Directed Technical Change and International Trade

Recent changes in comparative advantage in the largest OECD economies differ significantly from the predictions of Heckscher-Ohlin-Vanek theory. Japan's rising share of OECD machinery exports and the improvement in the comparative advantage of the USA and Germany in heavy industry were accompanied by growing scarcities of the factors used intensively in the favored sector of each country. Here we examine Acemoglu's (1998, 2002) hypothesis that technical change may be directed toward raising the marginal productivity of abundant factors. Testing this hypothesis with 1970-1992 export data from 14 OECD countries, we find evidence that international comparative advantage was reshaped by innovation biased toward the abundant factors in the largest economies.

Economic Development under Alternative Trade Regimes

How does openness affect economic development? This question is answered in the context of a dynamic general equilibrium model of the world economy, where countries have technological differences that are both sector-neutral and specific to the investment goods sector. Relative to a benchmark case of trade in credit markets only, consider (i) a complete restriction of trade, and (ii) a full liberalization of trade. The first change decreases the cross-sectional dispersion of incomes only slightly, and produces a relatively small welfare loss. The second change, instead, decreases dispersion by a significant amount, and produces a very large welfare gain.

Bundling under the Threat of Parallel Trade

This paper examines the use of bundling by a firm that sells in two national markets and faces entry by parallel traders. The firm can bundle its main product, - a tradable good- with a non-traded service. It chooses between the strategies of pure bundling, mixed bundling and no bundling. The paper shows that in the low-price country the threat of grey trade elicits a move from mixed bundling, or no bundling, towards pure bundling. It encourages a move from pure bundling towards mixes bundling or no bundling in the high-price country. The set of parameter values for which the profit maximizing strategy is not to supply the low price country is smaller than in the absence of bundling. The welfare effects of deterrence of grey trade are not those found in conventional models of price arbitrage. Some consumers in the low-price country may gain from the threat of entry by parallel traders although they pay a higher price. This is due to the fact that the firm responds to the threat of arbitrageurs by increasing the amount of services it puts in the bundle targeted at consumers in that country. Similarly, the threat of parallel trade may affect some consumers in the hight-price country adversely.
