Complementary or adverse? Comparing development results of official funding from China and traditional donors in Africa
No full textWhile China has become an important source of aid and other official funding for Africa, its coordination with other development partners remains limited, and its contribution to development has been questioned. Despite different development models represented by China and traditional donors, recent studies demonstrated that funding from the two has similar determinants, but little was done to systematically compare their role for development. The paper evaluate their impacts on infrastructure, governance, external debt sustainability and dependence on natural resources. Furthermore, we explore whether there are (dis)advantages from the presence of both donors. Overall, we find that China has similar, beneficial, impact when compared with traditional donors on all the development dimensions but debt. The presence of both donors, in turn, has a positive effect on debt sustainability, but negative impacts on the other dimensions. We interpret these results based on effective development cooperation principles of ownership, alignment, harmonisation, and accountability
Forecasting Russian Foreign Trade Comparative Advantages in the Context of a Potential WTO Accession
No full textFor the private and public sector in any particular country it is crucial to know, which industries may exhibit comparative advantages, that for some reasons are not realized. This can efficiently help all current and potential actors to improve their economic strategy both at the micro- and macroeconomic level. In this paper we propose an approach of forecasting comparative advantages dynamics in foreign trade. The instrument is based on relative price differences and is efficient for countries in the process of economic liberalization. An empirical analysis based on the example of Central and East European countries confirms a good performance in the sense of predictive power of this instrument. On the example of Russia, experiencing a period of economic liberalization and with the prospect to join the WTO agreements, we demonstrate which sectors are most likely to contain comparative advantages in the near future.comparative advantage, economy in transition, Balassa index, Lafay index
How different aid flows affect different trade flows: Evidence from Africa and its largest donors
No full textIn this study we compare the impacts of official finance coming from the largest donors of African countries on bilateral trade flows between the donor and the recipient. Applying a gravity model approach, we distinguish between development finance and other official flows. We find that official finance from all the donors stimulates export of goods to Africa, while trade flows in the opposite direction are fostered in the case of China and Europe, but not for the US. Despite some claims in the literature that aid from China aims at securing import of natural resources, we find evidence that countries receiving Chinese aid raise their bilateral export of manufactured goods and not of primary commodities. Finally, while for Europe and the US official flows other than development assistance play a bigger role in shaping trade flows, China primarily uses highly concessional and development oriented flows.

Factor-Biased Technical Change and Specialization Patterns
No full textWe analyze the medium- and long-run effects of international integration of capital markets on specialization patterns of countries. For that purpose, we incorporate induced technical change into a Heckscher-Ohlin model with a continuum of final goods. This provides a comprehensive theory that explains the dynamics of comparative advantages based on differences in effective factor endowments. Our model constitutes an appropriate framework for understanding the changes in industrial structure of foreign trade observed, e.g., in the CEE countries over the last two decades. In addition, our approach provides a theoretical foundation for the empirical prospective comparative advantage index (Savin and Winker 2009) with new insights into the future dynamics of comparative advantages. Eventually, the model may serve as a basis to set development priorities in countries being in the period of transition.Factor-biased technical change, continuum of goods, comparative advantage, factor mobility, innovation, knowledge spillovers

L'arche de Noé de Saint-Savin
No full textThe depiction of the ark at Saint-Savin-sur-Gartempe was noted mainly because of the two giant figures holding onto the roof of the ark. Similar representation can be found in the murals of the church of Saint Jean Baptist de Château-Gontier. The author shows their origin to be in Jewish legends. The distribution of the animals and humans in the ark points also to the same origins. The article compares the depiction of the ark in Saint-Savin with those of the illuminations in the manuscripts of the Caedmon poetry, wich shows angels in a somewhat similar position, with the Aelfric paraphrase, as well as the paintings by W. de Brailes, all of which show some traces of Jewish legends. The unconventional form of the sequence and continuity of the stories depicted in the vault painting in the nave of Saint-Savin and the direction of some of the depictions from right to left may point also to an earlier pictorial model of Jewish origin.La représentation de l'arche de Noé à Saint-Savin-sur-Gartempe et son exceptionnelle iconographie ont retenu l'attention des chercheurs essentiellement focalisés sur les deux personnages gigantesques agrippés à la toiture de l'arche. La même représentation figure à l'église Saint-Jean-Baptiste de Château-Gontier. L'A. en fait remonter l'origine aux légendes juives, origine qu'atteste également la distribution des animaux et des hommes aux différents points de l'arche. L'article compare la représentation de l'arche de Saint-Savin, d'une part avec celle des enluminures des manuscrits du poème de Caedmon, où les anges affectent une position quelque peu semblable, d'autre part avec celle de la paraphrase d'Aelfric et des peintures de W. de Brailes, où l'on relève aussi des traces de légendes juives. La forme non conventionnelle des séquences et le fait que la lecture de certaines images se fasse de droite à gauche renvoient aussi à un modèle pictural précoce d'origine juive.Friedman Mira.

Local and global minimizers for a variational energy involving a fractional norm
No full textWe study existence, uniqueness, and other geometric properties of the minimizers of the energy functional
∥u∥2Hs(Ω)+∫ΩW(u)dx,
where ∥u∥Hs(Ω) denotes the total contribution from Ω in the H s norm of u and W is a double-well potential. We also deal with the solutions of the related fractional elliptic Allen-Cahn equation on the entire space Rn . The results collected here will also be useful for forthcoming papers, where the second and the third author will study the Γ-convergence and the density estimates for level sets of minimizers

Absorptive capacity and innovation: When is it better to cooperate?
No full textCooperation can benefit and hurt firms at the same time. An important question then is: when is it better to cooperate. And how can an appropriate partner be selected? In this paper we present a model of inter-firm cooperation driven by cognitive distance, appropriability conditions and external knowledge. Absorptive capacity of firms develops as an outcome of the interaction between absorptive R&D and cognitive distance from voluntary and involuntary knowledge spillovers. Thus, we offer a revision of the original model by Cohen and Levinthal (1989) accounting for recent empirical findings and explicitly modeling absorptive capacity within the framework of interactive learning. We apply that to the analysis of firms' cooperation and R&D investment preferences. While the focus of this paper is limited to a static scenario, where the cognitive distance between cooperating firms is fixed and given exogenously, in Savin and Egbetokun (2012) we address the dynamic approach and provide more extensive simulation results
