This paper reports results of an empirical study on the effectiveness of labour market policy. Data from Austria, France, Germany, Great Britain, Sweden and the United States are used to apply a simultaneous equation model with wages and employment being the endogenous variables. In order to explain employment, the amount of unemployment benefits per unemployed (passive labour market policy) and payment for wage subsidies and training per employed and unemployed person (active labour market policy) are used in addition to real wages and output. Wages and output have their expected impact on total employment. It turns out that passive labour market policy has a negative, and active labour market measures a positive, effect on the number of persons employed. [ABSTRACT FROM AUTHOR]

This work examines the behaviour of the input and output measures of the R&D process in the United States, Germany, France and the United Kingdom, in the second half of the 20th century. The researcher and idea stock series can be construed as stationary fluctuations around a trend function, with a main breakpoint at the end of the 1960s. All the countries exhibit slower growth after their last breaks that during the decades preceding its first breaks. In this connection, the United States and Germany appear to represent the end points in the range of incidence. [ABSTRACT FROM AUTHOR]

French and US hospital technologies are compared using directional input distance functions. The aggregation properties of the directional distance function allow comparison of hospital industry-level performance as well as standard firm-level performance with regard to productive efficiency. In addition, the underlying constituents of efficiency in the short run, congestion and technical inefficiency, and in the long run, scale inefficiency -- are analysed by decomposing the overall measure. By virtue of using the directional distance function, it is also possible to obtain an estimate of a lower bound on allocative inefficiency. It is found that French and US hospitals use quite different technologies. Long run scale inefficiencies cause most of the French hospitals' inefficiency, while short run technical inefficiency is the main source of overall productive inefficiency in the US hospitals.
