Ricardo on machinery: an analysis of Ricardo's examples

The examples that are reported in the famous chapter “On Machinery” added by Ricardo in the third edition of his Principles are reconstructed and analyzed. Two sets of assumptions that rationalize the examples presented by Ricardo are identified: a) the innovation concerns an agricultural commodity and does affect neither which land is marginal nor the technology applied on the marginal land; b) the innovation concerns a non-basic commodity. Ricardo was aware of these two facts and he seems to have used them respectively in the first and second of his examples.     

Women Trailblazers in the Statistical Profession

A brief historical introduction to nine women who were trailblazers in the statistical sciences is presented. During their times, men dominated the profession. Yet we see how these women in their various ways blazed trails and as such became mentors and inspirations for generations of women practitioners who worked with them and followed in their footsteps.

Labour employed in production and labour commanded: a Ricardian conjecture

This paper explains the origin of some important ambiguitiesin the analysis of value and prices put forward by Smith inhis Wealth of Nations by considering the possibility that theyreflect a previous draft of the book where the quantity of labouremployed in production was indicated as the sole determinantof real price and exchange ratios. This conjecture is evidencedindirectly by the way in which Smith presented his own analysisat the end of Book I, Chapter IV; by some passages containedin Book I and Book II which suggest that the quantity of labouremployed in production should play a crucial role within theanalysis of exchangeable value; and by the important modificationsintroduced by Smith in Book I, Chapter VI, after the first editionof the Wealth of Nations was published.     

Product life cycle research: A literature review

The purposes of this paper are threefold: to review the scope of product life cycle (PLC) research; to pinpoint areas requiring further investigation; and to provide guidelines for future researchers. Because of the paucity of empirical evidence, only tentative conclusions are advanced. For example, the most common PLC pattern is the classical, bell-shaped curve, but it is not the sole shape. The application of various forecasting techniques across the PLC have met with merely moderate success. Very little research has been conducted either on how different characteristics of the firm influence the PLC or on the actual use of various PLC-strategy theories by business planners. Finally, investigators have focused almost exclusively on validating the existence of the PLC concept among nondurable consumer goods. Industrial items, as well as major product changes, have been nearly ignored. The main conclusion is that additional research-more diversified and extensive in nature-is needed on many PLC topics.     

Measuring managerial cognitive styles: On the logical validity of the Myers-Briggs Type Indicator

This study examined the validity of the sensing-intuition and thinking-feeling scales of the Myers-Briggs Type Indicator as a measure of cognitive styles (i.e., process). Using 20 full-time-employed graduate students in Business Administration as subjects, and simultaneous verbal protocols as a measure of process, only partial support for the scales was found. In particular, the sensing-intuition scale demonstrated greater convergence with processes hypothesized to be associated with it than did the thinking-feeling scale. Recommendations for improving the scales are made.

The sceptic as an economist's philosopher? Humean utility as a positive principle

Whereas in philosophy David Hume was long regarded as a negative thinker to be criticized rather than read, many thinkers interested in social and economic theory from Adam Smith onwards found key concepts, distinctions and problems as developed by Hume useful and inspiring. This applies not only to his seminal contributions to technical problems in economics. It is argued that the way in which Hume employed ‘utility as a positive principle’ (most notably in his ‘experimental’ moral theory) is of pivotal importance in this context. It allows for:

a. distinguishing between internal motifs and external circumstances and constraints; and for

b. making explicit the abstract logic of social interaction structures, mechanisms and processes.

Both are necessary conditions for employing the logic of social situations and mechanisms in the explanation of social institutions and economic processes. It moreover prepares the ground for the use of simplified or cartoon-like models of individual agency in economic and social theory, but also for its critique. On this basis, Hume's influence on various strands of social and economic thought, but also the specific differences with regard to more ‘rationalistic’ approaches (such as Hobbesianism or important versions of neoclassical economics) can be assessed more clearly.     

Selection and motivation of distribution intermediaries

This article reviews factors necessitating the application of effective selection and motivation criteria when using independent distributors. It reports findings concerning the criteria utilized by samples of US and UK manufacturing companies. Generally, there appears to be much that is acumenical in the efforts of firms in both countries. However, there also seems to be considerable scope for improvement in selecting and motivating distributors.
