I have argued that for the period from 1661 to 1850, patent data in England were consistent in that no official changes in methods and standards of issuance occurred. Book data on titles published on farming production methods were similarly consistent from 1523 to the mid-19th century because the market for books developed gradually and the technology of printing was not substantially changed until the mid-19th century.My main point is that data on output of titles of books on farming productive techniques in England are useful measures of technological change. Books did have information on good production methods and could express productive ideas where a patent may not be issued. Further, the literacy rate of farmers was high so that books were likely an important source of ideas on farming production methods. Finally, the fluctuations in the book data were highly related to the fluctuations in the patent data, suggesting that a common set of factors caused those fluctuations. The high correlations between the detrended book and patent data indicate that if we accept patenting as a useful measure of technology we may also accept book title output of a technical nature as a good measure of technical change.I used the data for a simple analysis of the trend growth rate of agricultural technology in England from 1551 to 1850. While there is limited evidence to show that the subperiod 1651–1750 saw a slowing in the trend of development of farming technology, I argue that a division of the entire period into subperiods is too simplistic. A more fruitful approach would be an analysis of the underlying forces that determined the trend of development of the technology of English agriculture.The next step is an analysis of the forces that influenced technological development of English farming. From an economic point of view, market forces play an important role in influencing technology. Because such an analysis deserves careful consideration, I leave that to another paper (see Sullivan and Simon, 1983). 相似文献

The study in this article involved the investigation of 15 carrier selection variables over three dimensions by three groups with high involvement in the purchasing decision—traffic managers, sales representatives, and sales managers. The primary focus of the study was the identification of significant differences in the assessment of importance of the technical abilities of a carrier, the service orientation of a carrier and the image of a carrier as perceived by sales managers and sales representatives representing the selling systems, and traffic managers representing the buying systems. 相似文献

Summary Dr. Holtrop's address on the occasion of the award of the Dr. N. G. Pierson medal to Professor C. Goedhart and to Professor G. A. Kessler answers the question why it is still meaningful to commemorate Dr. N. G. Pierson (1839–1909), the foremost Dutch economist of the 19th century. Pierson was successively a managing director and later governor of the Nederlandsche Bank (1868–1891), a professor of economics (1877–1886), a minister of finance (1891–1894 and 1897–1901) and a prime-minister (1897–1901). A brief outline is given of Pierson's publications in the fields of (1) methodology, (2) the social problem, (3) the international monetary system, and (4) equitable taxation. The address concludes with a quotation from Alfred Marshall's last letter to Pierson.

Based on data obtained from 359 idea evaluators, canonical correlation analysis was used to examine the relationship between several organizational factors and a set of criteria used in the evaluation of technical ideas. In contrast to other studies, it was found that organizational factors—assessed in terms of organizational climate—could be explained in terms of two dimensions: organizational clarity and risk. Technical evaluation criteria could be explained in terms of professional self-gratification and organizational responsibility. In light of the multivariate relationship among the two sets of factors, a number of organizational design implications are outlined. 相似文献

The present research involves determinant component analysis [3]. Specifically, the study assesses which components—price, product or environmental—are most important in the design of new entry strategy. Under conditions of abundance, industrial firms primarily analyzed price and product characteristics when making new product decisions. In choosing one supplier over another the stalwart buying motives have been quality, service and price [4]. However, these decision components were conceptualized in a period of abundance. Under conditions of scarcity, are price and product characteristics still important? Are environmental dimensions perhaps more important under shortage conditions when making new product decisions? Besides describing the key components that may be considered in new product programming, the article also outlines an approach that may be used to find determinant decision components. 相似文献

Conclusions For our purposes here, the analysis has been fruitful in that it has served to indicate and underscore in both general and
specific terms the sources and determinants of migration movement and the destination of migrants. The qualitative analysis
and the statistical test have led to several research conclusions. Both United States and Ghanaian migrants behave in accordance
with the migration concepts examined. Common relationships between migration and economic opportunity are apparent. While
push factors have generally initiated migratory movement among black Americans, particularly in respect to the South, both
groups tend to move to regions with better economic opportunities. In both cases, migration is a negative function of distance,
and a large labor force at the origin is a stimulus to out-migration at the origin. 相似文献

Summary This is a review article of D.B.J. Schouten's new book Macht en wanorde, Een vergelijking van economische stelsels (Power and Disorder, A Comparison of Economic Systems). After having summarised the book's contents, three points are discussed: (a) does the book offer a comparison of economic systems as its subtitle suggests; (b) how does Schouten's theory relate to disequilibrium analysis and does it give a better understanding of disequilibria than disequilibrium analysis; (c) is Schouten's proposal of a centrally-guided rate of return policy indeed to be preferred above a centrally-guided wage policy in order to overcome the basic problem in capitalist market economies of slow and sometimes perverse adjustments?D.B.J. Schouten,Macht en wanorde, Een vergelijking van economische stelsels, (Power and Disorder, A Comparison of Economic Systems), H.E. Stenfert Kroese b.v., Leiden/Antwerpen, 1980: Pp. 270.
