Experimental economics is a rapidly growing field of inquiry, and there currently exist several textbooks and surveys describing the results of laboratory experiments in economics. This primer, however, is the first hands-on guide to the physical aspects of actually conducting experiments in economics. It tells researchers, teachers and students in economics how to deal with human subjects, how to design meaningful laboratory environments, how to design experiments, how to conduct experiments and how to analyse and report the data. It also deals with methodological issues. It can be used to structure an undergraduate or graduate course in experimental economics.

In Ms contribution recent Dutch theoretlcal andpractical developments are discussed in computerized - semi-intelligent - assistance of legislators. Special attention ispaid to the so-called drafling-support Systems. In the Netherlands two drafting-support Systems are being — or have recently been — developed (LEDA, developed for the Dutch Ministry of Justice and OBW developed by the Dutch Ministry of Education and Science). This paper will deal with one of these Systems (the LEDA-system) in particular. In discussing the development, the structure and particular functionalities of the LEDA-system some general characteristics and possibilities of legislative draftingsupport Systems will be illustrated.

Hahn and Hird provide the first comprehensive analysis of the costs and benefits offederal economic and social regulation. They assess several alternative methods of measuring the effects of regulatory policies, noting the advantages and drawbacks of each. They find that previous estimates of the costs of economic regulation probably overstated the true costs by failing to distinguish between transfer payments and net changes in economic efficiency. Their study separates transfers from efficiency costs for each estimate and updates the figures for sixteen industries and seven areas of social regulation. Overall, they find that the efficiency cost due to economic regulation is large and that the benefit from social regulation is positive but small. Their study also finds a huge variation in estimates of the costs and benefits of particular regulatory policies, particularly in the transportation sector and in environmental protection. This variation indicates that most estimates may be merely "guesstimates". Nevertheless, Hahn and Hird argue that since the current political climate has increased the pressure on Congress to add regulatory burdens, the need to introduce such information into policy making has never been greater.
