Stationary monetary equilibria with strictly increasing value functions and non-discrete money holdings distributions: An indeterminacy result

In this paper, we present a search model with divisible money in which there exists a continuum of monetary equilibria with strictly increasing continuous value functions and with non-discrete money holdings distributions.     

An Analysis of Income Distribution between the North and the South: the Grossman–Helpman and Lai Results Re‐examined*

This paper studies the effects of labor supply on relative wages in a dynamic North–South model of trade. Lai (1995 )—a generalization of the Grossman and Helpman (1991a,b , ch. 11) models—showed that the relative wage of skilled (unskilled) labor in a region is positively (negatively) related to the supply of skilled (unskilled) labor in that region. These surprising results depend crucially on the specification of the functional form of the Southern imitation activity. We will show that these results (except for the relative wage of unskilled labor in Lai) are reversed in the case where the productivity of imitation depends only on the number of products the North manufactures.     

A Practical Teacher–Robot Collaboration Lesson Application Based on PRINTEPS

To support elementary school teachers in teaching by encouraging active learning while maintaining the interest of pupils, this study focuses on supporting teaching, learning, and monitoring the progress of students through a Teacher–Robot collaboration lesson application using not only laptops and tablets, but also robots and sensors. Since developing a lesson application is time consuming for teachers, we have developed an integrated intelligent application development platform named PRactical INTElligent aPplicationS (PRINTEPS) to aid Teacher–Robot collaboration. However, several functions and interfaces for education are missing. Therefore, in this study, we extend several functions for education to PRINTEPS. In addition, since it is necessary in learning and monitoring the progress of students to present learning content suitable to each pupil’s level of understanding, we also have provided support through the use of a tablet quiz system based on ontologies and rule bases. In the case study, we developed a Teacher–Robot collaboration lesson application and conducted lessons for sixth-grade pupils at an elementary school. From the case study, we have confirmed the effectiveness of our platform and the application.     

De‐commitment to losing strategic action: evidence from the divestiture of poorly performing acquisitions

We use a mental accounting framework to study the conditions in which CEOs de‐commit to poorly performing acquisitions and so become more likely to divest them. We test this framework by contrasting the experiences of 68 firms that divested acquisitions with a control sample of 68 firms that did not divest their acquisitions. Consistent with the theory that we use to explain and predict de‐commitment, our results suggest that poorly performing acquired units tend to be divested when executives can place them within ‘attributional accounts’ (i.e., accounts for the cause of the performance that do not incriminate them) and ‘comprehensive accounts’ (i.e., within the context of overall firm performance).

SEARCH AND VACANCY COSTS IN THE TOKYO HOUSING MARKET: ATTEMPT TO MEASURE SOCIAL COSTS OF IMPERFECT INFORMATION

The social cost of imperfect information, in terms of buyers' search costs and sellers' opportunity costs of vacancy, is estimated in the real estate market of resale condominiums in central Tokyo by using a new, comprehensive dataset of resale condominium transactions. The results suggest a substantial social cost. Specifically, if housing information were perfectly available and marketing time were null, sellers would get benefits of 22.59% of imputed net rents of their property. In addition, buyers would save 1,042,000 yen spent on search activities for one transaction, if information were perfect. This is equivalent to 13.2% of buyers' average annual income.     

A THEORY OF MONEY AND MARKETPLACES*

This article considers an infinitely repeated economy with divisible fiat money. The economy has many marketplaces that agents choose to visit. In each marketplace, agents are randomly matched to trade goods. There exist a variety of stationary equilibria. In some equilibrium, each good is traded at a single price, whereas in another, every good is traded at two different prices. There is a continuum of such equilibria, which differ from each other in price and welfare levels. However, it is shown that only the efficient single‐price equilibrium is evolutionarily stable.     

Technological diversification and firm's techno-economic structure: An assessment of Canon's sustainable growth trajectory

Contrary to the decrease in operating income to sales (OIS) in Japan's electrical machinery firms, Canon has demonstrated its increasing trend with increase of its technological diversification. These contrasts and Canon's conspicuous functionality development suggest that a virtuous cycle between its technological diversification strategy and increase in OIS can be the source of its sustainable growth.Prompted by this hypothetical view, this paper attempts to assess Canon's sustainable growth trajectory by elucidating a mechanism of its technological diversification system through an effective utilization of potential resources in innovation. By means of an epidemic function, the new approach for assessing marginal productivity of technology as well as functionality development is developed. Utilizing this approach, comparative empirical analyses are conducted focusing on the consequence of technological diversification and development trajectory in Japan's leading electrical machinery firms over the last two decades.
