Mixed duopoly: Differential game approach

This study formulates a dynamic mixed oligopoly model, in which a state‐owned public firm competes against a private firm over multiple periods. We adopt a differential game formulated by Fershtman and Kamien [Econometrica 55 (1987), pp. 1151–1164] and investigate how the dynamic competition affects the optimal privatization policy. We characterize the open‐loop Nash equilibrium (OLNE) and Markov‐perfect Nash equilibrium (MPNE). We show that in the MPNE, an increase in the degree of privatization has a nonmonotonic effect on the price, increasing it in a wide range of parameter spaces, which is in sharp contrast to the result in the OLNE or static analyses. We also find that the optimal degree of privatization is higher in the MPNE than that in the OLNE and static equilibrium. These results suggest that intertemporal strategic behavior changes the optimal privatization policy.     

COMMODITY CONTENT IN A GENERAL INPUT–OUTPUT MODEL

This technical paper provides a definition of ‘commodity content’ in extended von Neumann–Morishima models of production. Our definition admits as special cases the classical definition of ‘labour values’ in Leontief models, as well as Morishima's definition of ‘optimal values’ in a von Neumann model. Proper joint production, heterogeneous labour, durable consumption goods, household activities and disposal processes are all allowed for. We also propose a tentative mathematical criterion for defining bads and for distinguishing between unskilled and skilled labour.     

Market Size and Firm Location in a Service Industry

This paper investigates the welfare effects of firm location in a service industry. We consider the situation where firms determine their locations in either of two regions with a difference in market size. From the viewpoint of the consumers' welfare, there are too few firms in the large market and too many in the small market. However, from the viewpoint of the producers' and social welfare, the opposite is true. Further, an increase in the difference in market size is unambiguously unfavorable for the producers. On the other hand, such an increase is favorable for the consumers and the economy as a whole.     

Technical Changes and the Rate of Profit in Models with Joint Production and Externalities: A Duality Approach

This paper generalizes a result due to Okishio: the rate of profit increases as a result of cost reducing technical changes. The generalization is carried out first in a model of joint production which allows for new processes and commodities to be introduced or some of the old ones to be discarded. Then we consider nonlinear models incorporating external and internal (dis)economies     

Impact of International Remittances on Schooling in the Philippines: Does the Relationship to the Household Head Matter?

We study the impact of international remittances on schooling in the Philippines, taking into account the school‐age individual's relationship to the household head. This consideration is important because employment opportunities abroad may be taken at the expense of the quality of child rearing. Our estimation results indicate that there are, indeed, significant negative guardian effects on school attendance and education expenditures when children with overseas parents are looked after by a relative other than a parent or grandparent. However, these negative effects tend to be outweighed by the positive impact of remittance flows from overseas.     

How do the success factors driving repurchase intent differ between male and female customers?

As customers’ repurchase behavior leads to long-term corporate profitability, managers should know the success factors influencing repurchase intent. Knowledge of gender differences in these success factors would enable managers to separately optimize repurchase intent for men and women. This research thus develops original hypotheses on gender differences in the formation of repurchase intent. Based on hierarchical linear modeling of data from five countries and ten industries, this research finds that public brand image more strongly influences customer satisfaction and repurchase intent for women than for men. Perceived value has a weaker effect on repurchase intent for women than for men. The analyses do not detect any gender difference in the influence of customer satisfaction on repurchase intent. Contrary to conventional wisdom, relational switching costs more strongly influence repurchase intent for men than for women. Further analyses illustrate moderating effects of country differences in gender egalitarianism and of contextual differences between products and services.     

The Productivity Effects of Participatory Employment Practices: Evidence from New Japanese Panel Data

We report the first results for Japanese firms on the effects of clusters of participatory employment practices (or participation/employee involvement at the top level as well as at the grassroots level, and financial participation) by estimating production functions using new panel data. We find that the introduction of a group of complementary practices will lead to a significant 8–9 percent increase in productivity. However, the full productivity effect is felt only after a long developmental period.
