Imaging partons in exclusive scattering processes

The spatial distribution of partons in the proton can be probed in suitable exclusive scattering processes. I report on recent performance estimates for parton imaging at a proposed Electron-Ion Collider.Comment: 4 pages, 5 figures.

Introduction to GPDs and TMDs

Generalised parton distributions (GPDs) and transverse momentum dependent parton distributions (TMDs) describe complementary aspects of the three-dimensional structure of hadrons. We discuss their relation to each other and recall important theory results concerning their properties and their connection with physical observables.Comment: 12 pages, 8 figures. v2: reference correcte

International Trade in Intermediate Inputs: The Case of the Automobile Industry

International trade statistics and input-output tables are analyzed in order to test the hypothesis that international production networks have become more relevant. The share of imported inputs in the gross output value of the motor vehicle industry has grown significantly during the last two decades. Moreover, some low-income countries have become strong exporters of automobile parts, but this trade is mainly regional rather than global. Detailed results are presented in case studies on four major producers (the United States, Japan, Germany and the UK).international trade; intermediate inputs; international outsourcing.

On the determinants of credit allocation in developing countries: Empirical evidence for Brazil and Peru

Since the beginning of the eighties there has been an upsurge in the empirical analysis of the political economy of trade restrictions in industrialized and developing countries. These studies, which have been surveyed by Anderson and Baldwin (1981) and Amelung (1989) attempted to explain the structure of protection and changes therein by establishing a causal relationship between government intervention and characteristics of firms and industries in order to derive the determinants of government behaviour with respect to the implementation of trade barriers. It has been shown, that those sectors in a position to form effective pressure groups were more successful in obtaining effective protection. The ultimate aim of these studies was to develop further insights into the government's decision making process with respect to trade liberalization policies and structural adjustment programs. The key issue in designing a sustainable structural adjustment program concerns the appropriate trade-off between reducing the intensity of income redistribution effects and maintaining the efficiency of the adjustment process (Mussa (1986)).
