Study tour examines health care systems in Germany, Holland--Part II: The German system

In October 1992, the American College of Physician Executives sponsored a study tour to Berlin, Germany, and Amsterdam, Holland. Meetings were held with government officials, third-party payers, and providers, and on-site visits were made at hospitals, clinics, and academic centers. The purpose was to study the health care delivery system in those countries and to share some insights with the countries' hosts on the U.S. system. In a series of reports that began in the July issue of the journal, 5 of the 10 study tour participants describe their impressions of the tour and of the health care systems in the countries that were visited. In the first report, the health care delivery systems of the United States, Germany, and Holland were compared. In this report, the German system is analyzed in greater detail.     

On estimating census undercount in small areas

"Net undercount rates in the U.S. decennial census have been steadily declining over the last several censuses. Differential undercounts among race groups and geographic areas, however, appear to persist. In the following, we examine and compare several methodologies for providing small area estimates of census coverage by constructing artificial populations. Measures of performance are also introduced to assess the various small area estimates. Synthetic estimation in combination with regression modelling provide the best results over the methods considered. Sampling error effects are also simulated. The results form the basis for determining coverage evaluation survey small area estimates of the 1900 decennial census."     

Planning for technological innovation: Part II—investment in technological change in three major industries

In an article in the December 1977 issue the author described an analytical method to determine the reaction of British industry to the oil crisis. The purpose of this paper is to carry forward the discussion by examining and comparing circumstances in three British industries between 1963 and 1975.The paper aims first, to show how and why the cost structures of these three industries differ; second, to examine changes forced upon companies by inflation of earnings, statutory control of prices and the oil crisis; and finally to assess how far these congruent economic forces have impinged on tangible and intangible investment.The data used for this study were drawn from British and Canadian official statistics but, as described in Part 1, a new analytical technique was devised to give due weight to the full range of investment expenditure.     

Energy and the economy— A reply to Smil and Kuz

In the June 1976 edition of this journal Smil and Kuz discussed the case for saying that there are quite firm relationships between energy consumption and GDP. They argued broadly that there was no general relationship, but, instead, the individual countries are locked into individual patterns of energy consumption. The proponents of the ‘there is a relationship’ school of thought include the author of this reply who is employed in the Economics and Programmes Branch of the U.K. Atomic Energy Authority.     

A framework of decision making for technological change

The first article in this series2 drew a distinction between the costs of line operations- or current outputs—and those costs devoted to investment, or future outputs. As investment encompasses technological change—in practice it is dominated by it—this article examines some of the broader issues underlying decisions to invest and describes in outline a study being made of the economic criteria that are relevant to such decisions. In the longer term the objective is to develop a procedure or framework of criteria to assist the process of decision making; and this would include a frame of reference—a set of statistical time-series and analyses designed for the purpose.     

Innovation as the source of long term economic growth

This paper concerns some economic aspects of innovation particularly as the source of long term growth. Economic history supplies many examples of the rejuvenation of economies which, at various points in time, could legitimately have been considered ‘ageing’. The author asks ‘Could Britain's turn come now?’     

On the number of separable partitions

Consider partitions of a given set A of n distinct points in general position in ℝ ^d into parts where each pair of parts can be separated by a hyperplane that contains a given set of points E. We consider the problem of counting and generating all such partitions (correcting a classic 1967 result of Harding about the number of such partitions into two parts). Applications of the result to partition problems are presented.
