Cet article examine l’effet de l’intégration dans les chaînes valeur mondiales (CVM) sur la transformation structurelle des économies d’Afrique subsaharienne. Partant d’un échantillon 46 pays, observés sur période 1995 – 2018, nous estimons un modèle cointégration en données panel par méthode du ...

The unbinding process of E2020 ((R,S)-1-benzyl-4-[(5,6-dimethoxy-1-indanon)-2-yl]-methylpiperidine) leaving from the long active site gorge of Torpedo californica acetylcholinesterase (TcAChE) was studied by using steered molecular dynamics (SMD) simulations on a nanosecond scale with different velocities, and unbinding force profiles were obtained. Different from the unbinding of other AChE in...

We explore the implications of migrants’self-selection for the determination of immigration policy in a simple model where incentives and resources to migrate vary with skills. We show how self-selection determines the response of potential migrants to immigration policy changes, which is crucial for predicting the e¤ects of such policy in the receiving country. For example, restricting immigra...

Special and differential treatment (S&D) for developing countries continues to be a defining feature of the multilateral trading system. This paper seeks to address key aspects of what has become an increasingly entangled and multi-faceted discussion. The paper begins by reviewing the historical context in which the relationship of developing countries with the multilateral trading system evolv...

The terms of trade debate initiated by Raul Prebisch and Hans Singer over 60 years ago continues to this day and is unlikely to be resolved soon. However, even if Prebisch and Singer are right and the terms of trade of countries exporting primary products are falling, to suggest that these countries should diversify away from the production of mineral commodities and other primary products, as ...

This paper analyzes the net effect of integration, as a measure of changes in trade barriers, on reducing the border effects between European countries. In order to study this contribution, we examine the size of home bias in the market for goods among 18 European countries over the period 1995-2006. The construction of a gravity model, using disaggregated data for 23 sectors, allowed us to com...

We develop a dynamic model of intermediate goods trade in which the pattern and the extent of intermediate goods trade are endogenous. We consider a small open economy whose …nal good production employs an endogenous array of intermediate goods, from low technology (high cost) to high technology (low cost). The underlying intermediate goods technology evolves over time. We allow for endogenous ...

The literature on trade facilitation has mostly focused on implications for trade volumes. However, recent theoretical contributions have emphasized that trade costs – such as transaction costs related to cross-border trade procedures – affect both the traded volumes of “old” goods (the intensive margin) and the range of traded goods (the extensive margin). This paper therefore tests whether tr...

This paper investigates the determinants of the real exchange rate (RER) in Ethiopia. In particular, it assesses whether large capital inflows (e.g. foreign aid and remittances) have an impact on the RER. This empirical exercise tries to improve the current literature in a number of ways: (i) the use of quarterly data provides a larger sample size and enables the modelling of important intra-ye...
