Impact of the WTO on agricultural and food policies

Most studies on the impact of WTO agreements on policies are ex ante simulations or focus on trade effects. We ex post estimate the impact of the WTO on agricultural policies, including both the total transfers by the policies and the policy instruments used, in particular their market distortions. We use OECD data on total support and instrument choice in agricultural policy. Our empirical analysis provides evidence that the WTO did not cause a significant reduction in the total amount of support to agriculture but that it caused a significant shift from distortionary to less distortionary instruments

Bringing the benefits of David to Goliath: special economic zones and institutional improvement

The theory behind special economic zones (SEZs) focuses on their role in overcoming broader policy failings in a country. This paper hypothesizes that the ability of smaller countries to reform more quickly provides a theoretical ‘missing link’ as to how SEZs can assist reform, developing the idea of SEZs as a ‘small country in a large country’. Using a new database, the paper tests this proposition by examining if SEZs have actually been able to spur on institutional improvement in large countries. Results show that SEZs do influence the institutional development of a country, contingent upon prevailing institutional trends

Middle East - North Africa and the millennium development goals : implications for German development cooperation

          Closed-loop controlled combustion is a promising technique to improve the overall performance of internal combustion engines and Diesel engines in particular. In order for this technique to be implemented some form of feedback from the combustion process is required. The feedback signal is processed and from it combustionrelated parameters are computed. These parameters are then fed to a control process which drives a series of outputs (e.g. injection timing in Diesel engines) to control their values. This paper’s focus lies on the processing and computation that is needed on the feedback signal before this is ready to be fed to the control process as well as on the electronics necessary to support it. A number of feedback alternatives are briefly discussed and for one of them, the in-cylinder pressure sensor, the CA50 (crank angle in which the integrated heat release curve reaches its 50% value) and the IMEP (Indicated Mean Effective Pressure) are identified as two potential control variables. The hardware architecture of a system capable of calculating both of them on-line is proposed and necessary feasibility size and speed considerations are made by implementing critical blocks in VHDL targeting a flash-based Actel ProASIC3 automotive-grade FPGA
