The man-machine interface

The basic objective of this article is to define a composite measure of human capabilities that could also be used to measure the “skill” requirements of various manufacturing tasks. In the course of our research, however, we have come to the conclusion that most human workers (at least in the “semiskilled” categories) are not employed for their manual skills, or dexterity, but for a different purpose. Although our basic objective remains unchanged, our research focus has shifted to the emerging competition between human workers as machine process controllers in certain highly engineered environments, and the use of sensor-based, computerized systems for the same purpose.     

Formal schooling and workforce participation in a rapidly developing economy: evidence from “compulsory” junior high school in Taiwan

Using 18 consecutive household surveys, this study explores the impact of Taiwan's extension of tuition-free education from 6 to 9 years upon schooling and labor market outcomes (participation, sector/class of activity, and work income). I estimate upward shifts relative to preexisting trends of more than 0.4 years of education for males and 0.25 years for females in the first six cohorts affected by “compulsory” junior high schooling. Utilizing inter-cohort variation within an instrumental variables (IV) strategy, I find larger effects of schooling on females' workforce participation and total earnings, even controlling for selection.     

Human capital depletion, human capital formation, and migration: a blessing or a “curse”?

We specify conditions under which a strictly positive probability of employment in a foreign country raises the level of human capital formed by optimizing workers in the home country. While some workers migrate, “taking along” more human capital than if they had migrated without factoring in the possibility of migration (a form of brain drain), other workers stay at home with more human capital than they would have formed in the absence of the possibility of migration (a form of brain gain).     

The research strategy in management of technological innovation

The increasing importance of technology in the application world has imposed high demand on the research community for insightful and useful principles about “management of technological innovation” (MTI). This paper examines the academic legacy in terms of conceptual categories, causal relationships and taxonomy of relevant systems, and asserts from a system perspective that MTI as an applied science is still in its infancy.Based on methodological argument, this paper warns of the danger of hasty compromise of strategically important topics to “popular” definition of “researchability,” and suggests several research guidelines and approaches for this young interdisciplinary discipline:

1. (1)To explore new frontiers, use “proximate variables,” consider contextual factors and causation in broad terms, conceptualize “independently,” and pay more attention to case study method.

2. (2)To understand driving forces, be aware of practice, and focus on internal dynamics.

3. (3)To transcend complexity, adopt a hierarchical structure perspective and state-and-flow concept, and condense findings into configurations.

Finally, this paper urges the formation of an overall research strategy to accelerate the accumulation of MTI grounded knowledge.     

Can Japan succeed in “Chigyo-ka” (intelprise-formation)?

There are two aspects in today's information revolution that started in the late 1970s. The first is an aspect referred to as “the third industrial revolution,” which triggers the transition to the “21st century system of Industrialization.” The information revolution in this sense brings the creation of new “breakthrough industries (new multimedia industries).” And the second aspect of the information revolution possesses the characteristics of both a technological revolution and a social revolution and brings about the arrival of the third phase of the historical evolutionary process of the modern civilization, which proceeds through three phases, namely “militarization, industrialization, and then informatization.”If the bearers of modern industrialization are a “group of enterprises” that have been engaged in the race in order to gain “wealth” (generalized means of exchange/exploitation power), and if these enterprises' activities have been exercised in the world market where their products have been sold, then it is appropriate to call the bearers of informatization a “group of intelprises.” They will be engaged in the race to gain “wisdom” (generalized means of persuasion/induction power), then stages of their activities can be called a “global intelplace” where “sharables,” that is, information and knowledge, will be disseminated. And now, toward the 21st century, the third phase of modernization, which can be called the “informatization/intelprise formation” or the “wisdom game” (intellectualism), is about to begin.Japan's “ie society (a society based on the ie principle—literally, it means “house” but here it is interpreted as cultural principle for organizing a society), which has been going through the process of evolution on the Japan Archipelago, has developed a network-based organization with little stratification within its infrastructure. In this sense, Japanese society can be characterized as a “network-oriented society” in which intelprises and an intelplace in the broad sense have functioned as the essential components of the society since Middle Ages. In general, an intelplace and intelprises that operate actively within this framework serve as the flexible bases for different types of social relations and institutions, such as states and markets and eventually integrate these into the society to a certain extent. In fact, it took place quite regularly during the modernization “in the narrow sense,” or Westernization of Japanese society after the Meiji Restoration. There exist some problems, however. Some of the characteristics found in Japanese society may become obstacles to activities aimed at the sharing and promotion of information and knowledge in the global intelplace and Japanese participation in the “wisdom game.” Badly needed are serious efforts for Japanese intelprise-formation to reduce these obstacles as much as possible.     

Absenteeism: A comparison of incentives in alternative organizations

This paper uses a game-theoretic model to analyze the incentives workers may have to play “hookey” from work given that there is an outwardly unobservable probability of being sick and thus being unable to work. We compare incentives and equilibria in labor-managed firms (LMFs) and in profit-maximizing firms (PMFs), both in single-period and repeated games. We show, among other things, that in an egalitarian LMF there are circumstances under which members will not work when it is optimal to work, while the PMF suffers from the opposite problem; daily paid workers will work even when it would be better if they did not.     

A model of “coupled” technology transfer : A logistic curve approach

This article presents a mathematical model relating to the technology transfer problem. The origin of the problem stems from the existing trade-offs between the strategies of “technological progressiveness” and “static efficiency” employed by firms or countries defined as “leaders” and “followers,” respectively. The formulation of the model is based on the assumption that the technological development of a firm or a country follows a logistic growth curve when related to a specific technology. During the process of a “coupled” technology transfer, the development of the follower changes and its behavior is described by a first order nonhomogenous deferential equation. Different scenarios of the “coupled” technology transfer between the leader and the follower are being discussed.     

When does the majority become a majority? Empirical analysis of the time at which main market adopters purchase the bulk of our sales

The idea of a dual-market structure in the early stages of a product's life cycle has become one of the most widely accepted ideas among new product marketing practitioners in the past decade. Concepts such as “Early Market/Main Market” and “Visionaries/Pragmatists” have entered the lexicon of high-tech executives to express the notion that the market for new products is composed of early and main markets with a discontinuity in the diffusion process in between them. Moreover, these concepts have been at least partially tested and verified in the marketing academic literature in the past few years.We extend this branch of research by investigating the timing issues in dual-market cases. We define Change-of-Dominance Time (CD-Time) as the number of years it takes main market adopters to outnumber early market adopters. We empirically investigate this timing issue on a comprehensive data set of new product sales in the consumer electronics industry. We find that regarding explanatory determinants of CD-Time, external influence, such as advertising, to the early market is the most important explanatory variable.We examine the relationship between CD-Time and other early product life cycle phenomena: Takeoff, Saddle, and Rogers' size of adopter categories. We found relatively high correlations between these phenomena and CD-Time.The answer to the question “When does the majority become a majority?” is indeed “at 16%”! In a dual-market setting, the average time at which the main market outnumbers the early market is when 16% of the market has already adopted the product. In terms of time, in 75% of the cases the majority becomes a majority in 5 to 10 years.     

Technological generalizations and leitbilder—the anticipation of technological opportunities

Recent national technology foresight studies as well as the Millennium Project of the American Council for the United Nations University are very much based on “nodes of discussion.” These short statements are called, e.g., topics, issues, or developments. This article provides a framework for the classification and analysis of nodes related to future technological development. Key concepts of the article are “technological generalization” and “leitbild.” The topics in the technology foresight Delphi studies can be seen as different kinds of generalizations from already realized technological developments. Leitbild is a German word. Its most general meaning is a guiding image. Like a common vision, a leitbild creates a shared overall goal, offers orientation toward one long-term overall goal, and provides a basis for different professions and disciplines to work in the same direction. The analysis of leitbilder and emerging technological paradigms might contribute to the construction of topics and issues and to the argumentation processes related to them.     

Critical Success Factors for Business Reengineering and Corporate Performance: The Case of Korean Corporations

This article briefly reviews the literature on business reengineering (BR), analyzes critical success factors (CSFs) for BR, develops a BR-CSFs model, empirically tests the model on Korean firms, and investigates the impact of BR on corporate performance in Korea. Many Korean firms are attempting to transform from Japanese- to American-style business management. As part of this process, BR has gained substantial critical mass as the first widely accepted American-born management methodology accepted in Korea. While Western-based BR methodologies provide general procedures and techniques the CSFs listed in this research focus on the key factors that Korean firms generally confront. In the present research, 20 CSFs, taken from a literature review were divided into four categories: strategic, organizational, methodological, and technological/educational. A survey was developed to assess the firm-specific importance and development of each of these CSFs. Survey responses from 162 Korean corporations indicate a positive association between the designated CSFs and corporate performance. Korean BR team leaders and CEOs/COOS rate “strategic” and “methodological” CSFs as most important while “organizational” and “technological/educational” CSFs are considered less important, a rank ordering challenged by the authors.     

An introduction to nanotechnology policy: Opportunities and constraints for emerging and established economies

Nanotechnology has captured wide attention all over the world and excited the imagination of young and old alike. Interest in the subject has increased remarkably during the last few years because of potential technological applications, and commercial interest has skyrocketed. The promise of nanotechnology as an economic engine that can redefine the wellbeing of regions and nations is pervasive; yet the imprecise language, and overuse of the term nanotechnology, has made that term fuzzier, broader, and trendier than many imagined possible. This is especially evident in nanotechnology market projections, which rose dramatically over the past five years as more traditional “product families” were engulfed by the expanding use of the term. Government policy regarding nanotechnology has often resembled an embrace of imagination rather than a systematic use of what Sun Tzu and others have taught about strategic decision making. Further, if nanotechnology is truly the next wave of technology product paradigms, how will we provide an educated workforce to support it? Moreover, in company with these societal benefits come increased societal risks. This paper is intended to provide policy makers and strategists with observations that might limit actions such as those that led to the “over-hype” of nanotechnology and to the fear (or discounting) of societal risks. In the latter case we might learn from the experiences of policy makers connected with other emerging enabling-technology bases, such as nuclear energy and, to a lesser extent, the “dot-com” boom.     

Alternate forecasts of the job content and skill requirements of the American economy in 1980

This paper analyzes the potential job content and skill requirements of the American economy in 1980 under three alternate economic futures. Detailed occupational manpower requirements are generated on the basis of a “Status Quo” economy, a “Social Welfare” economy, and a “Defense” economy in the near future. Occupational manpower requirements are then translated into a Job Family-Skill Content classification to determine how these alternate national priority choices may affect future requirements for specific jobs, skills, educational preparation, and vocational training. The results obtained indicate the job families and skill classifications most sensitive to changes in basic economic parameters, and also identify long run trends in manpower and educational requirements unaffected by shifting social priorities and patterns of federal expenditures. The implications of these findings for manpower and educational planning are briefly discussed.     

Conflict in the labor market: Seniority rules and unemployment

This paper examines the macroeconomic implications of two labor-market institutions that play an important role in worker-management interactions: seniority-based layoffs and majority voting on wage proposals. Together, these make the median worker, rather than the marginal worker, the important decision maker for wage and employment outcomes. Since he is risk-averse, he will trade off higher wages for greater security of employment; therefore, the equilibrium level of unemployment will be much less than 50%, but higher than the conventional natural rate of unemployment. Median-worker behavior helps to explain both the greater frequency of excess supply than excess demand (59.4% versus 40.6% of the time since 1890) and the wage concessions of 1981–1983. A new Phillips curve is derived which incorporates systematic influences of the size of the labor force (to correct for the inappropriate measure of excess supply) and Tobin's “q” variable (to measure the risk of unemployment for the median worker). With U.S. data for 1957–1983, this new Phillips curve has a higher explanatory power than the traditional one. Additional forces that influence wages and employment in this setting are identified: firms have an incentive to bargain actively over wages rather than accept union demands passively and senior workers have a “social contract” with junior workers that reduces the extent to which the former exploit the latter.     

Exact arbitrage, well-diversified portfolios and asset pricing in large markets

For a market with an atomless continuum of assets, we formulate the intuitive idea of a “well-diversified” portfolio, and present a notion of “exact arbitrage”, strictly weaker than the more conventional notion of “asymptotic arbitrage”, and necessary and sufficient for the validity of an APT pricing formula. Our formula involves “essential” risk, one based on a specific index portfolio constructed from factors and factor loadings that are endogenously extracted to satisfy an optimality property involving a finite number of factors. We illustrate how our results can be translated to markets with a large but finite number of assets.     

Does consumption respond to predicted increases in cash-hand availability?: Evidence from the Italian “severance pay”

We examine whether Italian household consumption exhibits excess sensitivity to “severance pay”, a sizable lump-sum that workers receive at job termination. We find no evidence of excess sensitivity of non-durable expenditure to this anticipated cash-in-hand change.     

Competitive capitalism and cooperative labor management in a dynamic nutshell

Competitive capitalism and co-operative labor management are both formulated as differential games: The former, as a game between capitalists and workers, and the latter as one between an elected council and workers. The two systems are compared against the background of neoclassical optimal growth theory, at their respective equilibria and in terms of their rates of approach toward these states, all within a dynamic “nutshell” model extended from the static one of Dirickx and Sertel (1979).     

On Forecasting Discontinuities

Too much has been written about forecasting trends via “envelope curves.” To plot a straight line on log-paper is a no-brainer. The special phenomenology of phase changes, catastrophes, or “crashes,” and their key evolutionary role is the subject of this article. There is no unique way of forecasting such events, but one indicator is an apparent inconsistency between two or more extrapolations with each other. Alternatively, a catastrophe may be signalled when a trend extrapolation encounters a natural limit. A number of possible discontinuity scenarios are sketched, although overall, the article laments the lack of theorization in forecasting disconuities.     

Influence of decision styles on use of decision models

This article discusses how the “decision style” of an administrator influences the adoption and use of particular decision models. Several “interactive” and “analytical” decision models often used to guide decision making are described and critiqued to point out their virtues and deficiencies. Propositions are suggested that contend that “systematic,” “judicial”, “speculative”, and “intuitive” styles have clear-cut preferences for a particular decision model. This model seems to be used, even when another would be more suitable. Effective decision makers are postulated to adapt their styles, or at least to see the benefits of different styles. Mixed-mode models are proposed that seem to simulate the behavior of successful decision makers.     

Imitation processes with small mutations

This note characterizes the impact of adding rare stochastic mutations to an “imitation dynamic,” meaning a process with the properties that absent strategies remain absent, and non-homogeneous states are transient. The resulting system will spend almost all of its time at the absorbing states of the no-mutation process. The work of Freidlin and Wentzell [Random Perturbations of Dynamical Systems, Springer, New York, 1984] and its extensions provide a general algorithm for calculating the limit distribution, but this algorithm can be complicated to apply. This note provides a simpler and more intuitive algorithm. Loosely speaking, in a process with K strategies, it is sufficient to find the invariant distribution of a K×K Markov matrix on the K homogeneous states, where the probability of a transit from “all play i” to “all play j” is the probability of a transition from the state “all agents but 1 play i, 1 plays j” to the state “all play j”.
