Estimation of the most influential science and technology factors for economic growth forecasting by soft computing technique

Economic growth may be developed on the basis on combination of different factors. In this investigation was analyzed the economic growth forecasting based on the different factors. The main goal was to analyze the influence of science and technology factors on the economic growth. Gross domestic product (GDP) was used as economic growth indicator. The method of adaptive neuro fuzzy inference system (ANFIS) was applied to the data in order to select the most influential factors for the GDP growth rate forecasting. Ten inputs are considered: research and development (R&D) expenditure in GDP, scientific and technical journal articles, patent applications for nonresidents, patent applications for residents, trademark applications for nonresidents, trademark applications for residents, total trademark applications, researchers in R&D, technicians in R&D and high-technology exports. The ANFIS process for variable selection was also implemented in order to detect the predominant factors affecting the forecasting of GDP growth rate.     

Earnings Management in Domestic and Foreign IPOs in the United States: Do Home Country Institutions Matter?

Using a large sample of domestic and foreign IPOs in the US, we investigate how threats of enforcement by the Securities and Exchange Commission (SEC) and private litigation influence earnings management in IPO prospectuses. We propose that perceptions of foreign institutions may influence SEC enforcement action and private litigation. We provide evidence that enforcement and litigation threats are negatively related to the strength of legal institutions in the foreign IPO’s country of origin. We find earnings management is more pronounced in foreign IPOs from countries with strong legal institutions. We further explore whether earnings management is priced in the IPO market and find no relation between IPO proceeds and earnings management. Our results are consistent with upward earnings management as in Stein (1989), the magnitude of which is reduced when the anticipated cost of enforcement and litigation is higher. Collectively, our results cast doubt on the validity of the bonding hypothesis.     

A model of cost-based transfer pricing

In most decentralized organizations, goods and services are transferred between divisions. These transfers are frequently recorded in the accounting books of the divisions; the term transfer price refers to the dollar amount of the interdivisional exchange. This study considers two main issues: (i) the costs and the benefits of delegating decisions through a system of transfer pricing and divisional performance evaluation, and (ii) the performance of one common method of pricing intrafirm transactions: cost-based transfer pricing.The study analyzes a firm in which each divisional manager has better information about the divisional environment than what is known by the firm's top management. The first half of the paper demonstrates that the firm can attain the optimal level of profits with a compensation system utilizing (i) reports by divisional managers describing in complete detail each manager's private information, and (ii) divisional performance evaluation with cost-based transfer pricing. Next, a situation is considered in which divisional managers are not able to communicate their private information to the firm's top management because of complexity of divisional environments or managers' specialized expertise. In this bounded-rationality setting, a managerial-compensation system employing cost-based transfer pricing allows the firm to earn strictly higher expected profits than if all decisions are made by the firm's top management relying on divisional managers' reports.Financial support from the Unisys Corporation is gratefully acknowledged.     

Subjective probabilities on “small” domains

The Savagian choice-theoretic construction of subjective probability does not apply to preferences, like those in the Ellsberg Paradox, that reflect a distinction between risk and ambiguity. We formulate two representation results—one for expected utility, the other for probabilistic sophistication—that derive subjective probabilities but only on a “small” domain of risky events. Risky events can be either specified exogenously or in terms of choice behavior; in the latter case, both the values and the domain of probability are subjective. The analysis identifies a mathematical structure—called a mosaic—that is intuitive for both exogenous and behavioral specifications of risky events. This structure is weaker than an algebra or even a λ-system.     

Statement of editorial policy

Systematic strategic management is a recent and still developing concern of both practitioners and students of management. It is necessary, therefore, to define in this first issue of the Strategic Management Journal (SMJ) both the limits and the contents of the subject which will be welcomed to its pages. Since we hope to attract our readers and contributors from both practice and academia, it is appropriate to describe strategic management from their respective viewpoints.     

The road not taken: competition and the R&D portfolio

This article examines the effects of market structure on the variety of research projects undertaken and the amount of duplication of research. A characterization of the equilibrium market portfolio of R&D projects and the socially optimal portfolio is provided. It is shown that a merger decreases the variety of developed projects and decreases the amount of duplication of research. An increase in the intensity of competition among firms leads to an increase in the variety of developed projects and a decrease in the amount of duplication of research.     

Uncertainty and the specificity of human capital

This paper studies the choice between general and specific human capital. A trade-off arises because general human capital, while less productive, can easily be reallocated across firms. Accordingly, the fraction of individuals with specific human capital depends on the amount of uncertainty in the economy. Our model implies that while economies with more specific human capital tend to be more productive, they also tend to be more vulnerable to turbulence. As such, our theory sheds some light on the experience of Japan, where human capital is notoriously specific: while Japan benefited from this predominately specific labor force in tranquil times, this specificity may also have been at the heart of its prolonged stagnation.     

Characteristics of learning computer-controlled mechanisms by teachers and students in a common laboratory environment

Growing popularity of robotics education motivates developing its didactics and studying it in teacher training programs. This paper presents a study conducted in the Department of Education in Technology and Science, Technion, in which university students and school pupils cope with robotics challenges of designing, building and operating computer-controlled mechanisms. The university students were involved in developing robot prototypes and related instructional materials, and assisted in teaching robotics and guiding projects to middle school and high school pupils. The study focused on behaviors of the two groups of learners and aimed to elicit and analyze typical characteristics of learning in the developed robotics environment. We collected qualitative data on learning through robot design and experimentation activities and, by means of the ground theory method, elicited and analyzed typical behavioral characteristics of students’ and pupils’ learning: self-confidence, help, collaboration, interest, seriousness, self-dependence, learning effort, responsibility, coping with learning pressure, learning through observation, and perseverance. As found, the behavior characteristics evolve in the course of robotics studies and their evolution can give indication on the development of the desired competences.     

How do threshold firms sustain corporate entrepreneurship? The role of boards and absorptive capacity

As companies move from one stage of their cycle to the next, they often have to revamp their skills and build innovative capabilities to survive, achieve profitability, and stimulate growth. Corporate entrepreneurship (CE) activities give these firms a foundation for building and exploiting these capabilities. In turn, stimulating and sustaining CE requires the infusion of resources and new knowledge into the firm's operations, using multiple external sources. In this paper, we highlight the importance of boards of directors and absorptive capacity for gaining access to varied and current knowledge that enriches CE. We suggest that boards and absorptive capacity complement each other in fueling CE activities. Further, boards can sometimes substitute for poor absorptive capacity and vice versa, influencing the intensity of CE activities. Managing these complementarities (or substitutions) is crucial for sustaining CE initiatives and creating value from them.
