    Abstract: A non-repairable system is considered and the problem of finding its optimal preventive replacement time is revisited. In addition to minimizing the expected cost per unit time in a cycle, we also consider its variance as the measure of the risk of the optimal decision. A multi-objective optimization problem is then formulated where the two objecti... Show More

    Abstract: The classical formula of certainty equivalent is reconsidered. Based on a modified proof of the original formula several alternative methods are derived with different orders of magnitude of their errors. This new method is then compared with the classical formula in a computer study showing the advantage of the new approach. Practical applications... Show More

    Abstract: By relaxing the common assumption of purely self-interested preferences in contests, we study contests in which players care not only about their own material payoffs but also about other players’ payoffs, a scenario we term “interdependent preferences.” In addition, we identify three possible types of heterogeneity among players in contests. First... Show More

    Abstract: We use the New Keynesian continuous-time framework to theoretically investigate the effects of a lag in a central bank’s response to economic fluctuations (i.e., monetary policy lag) on local equilibrium determinacy. In the case of a policy without lag, equilibrium is indeterminate even though a central bank’s policy response is sufficiently active... Show More
  • The Balanced Budget Multiplier and Labour Intensity in Home Production

    Abstract: This paper shows that the labour intensity of home production of a final consumption good affects national income and income multiplier effects of public expenditure financed by taxation. A reduction in labour intensity increases the level of national income but decreases the magnitude of the balanced budget multiplier effect. This result holds whe... Show More

    Abstract: Growth effects of R&D, especially in the service sector, are focused in this paper. By using a Romer type growth model with a R&D sector and a final goods retailing sector, we point out growth effects from the labor share of the R&D sector and the service sector. From the empirical analysis on the steady state equation, a positive per-capita income... Show More

    Abstract: We examine the implication of the assumption in two types of regulatory environments that a new entrant is an equally efficient competitor, on which the price squeeze test is built. Under partial regulation the entrant exits a market because of the higher access rates set by the authority. If we consider this assumption under no regulation, the ent... Show More

    Abstract: This paper constructs an endogenous growth model where the educational sector (higher education) produces human capital and social knowledge by education and research activities. The steady state growth paths are studied for market economy where the educational sector is financed by the income tax imposed on household and the rent on use of social ... Show More

    Abstract: In this study, we investigate the non-linearity of the Japanese business cycle based on the theoretical concept of the limit cycle. To analyze the time series of capital stock and GDP simultaneously based on the theoretical relationships predicted by the limit cycle, we incorporate the capital coefficient into a Kaldor-type dynamic model and apply ...

    Abstract: This paper examines inflation dynamics in Japan through estimations of the hybrid New Keynesian Phillips Curve. The estimation with the observed inflation rate in the corporate goods price index and that with the estimated firm-level expected inflation rate are considered. The firm-level expected inflation rate is estimated by the Kanoh (2006)-type... Show More

    Abstract: Friedman (1968) proposes a constant money growth rate rule to establish the stability of the market economy. We examine whether his suggestion is reasonable or not. We seek to develop the Vanderkamp (1975) model, which captures the essential points of monetarism: the quantity theory of money and the natural rate of unemployment. Our main finding is... Show More

    Abstract: An elementary analysis is developed to determine the stability region of certain classes of ordinary differential equations with two delays. Our analysis is based on determining stability switches first where an eigenvalue is pure complex, and then checking the conditions for stability loss or stability gain. In the cases of both stability losses a... Show More
