POPULATION AGING AND CONSUMPTION INEQUALITY IN JAPAN

This paper analyses how consumption inequality within a fixed cohort grows with age using Japanese household microdata. Following the method developed by Deaton and Paxson (1994), we obtain the following results. First, consumption inequality starts to increase at the age of 40. Second, younger generations face a more unequal distribution from the beginning of their life-cycle. Third, half of the rapid increase in the economy-wide consumption inequality during the 1980s was caused by population aging, while one-third was due to the increasing cohort effect. The paper compares the above results with those of Deaton and Paxson.     

Sequential product positioning in the presence of an asymmetric network externality intensity

In this study, we analyze the sequential decisions on product positioning of two firms in the presence of network externalities. One commonly accepted phenomena in a market where a network externality arises is the first‐mover advantage, in which the first entrant into a market can earn a higher profit than later entrants. However, in some recent online services markets, we see that the second mover earns a higher profit than the first mover. This occurs because the second mover strengthens its variety of available functions and services markedly, thereby facilitating consumers' work and communication with its main product, which we call network externality intensity. Based on this observation, we analyze sequential positioning in Hotelling's framework by incorporating an asymmetric network externality intensity between firms. We show that unlike the results of previous related studies, both first‐ and second‐mover advantages can appear in the equilibrium depending on the relationship of the network externality intensity between firms; further, they do not change monotonically with the level of network externality intensity.     

SIZE DISTRIBUTION OF WORKERS' HOUSEIIOLD INCOME AND MACROECONOMIC ACTIVITIES IN JAPAN: 1963–88

An attempt is made to examine empirically the relationship between the size distribution of workers' household incomes and the variables expressing macroeconomic activities. As a preliminary implementation, the income shares are first estimated by decile groups and several subdivided top income groups. Applying Blinder and Esaki's regression approach to the estimated data, the ratio of job offers to applicants, inflation rate, and the terms of trade arc found to significantly affect the distribution. Of these variables, the terms of trade should be taken into account to ascertain precisely the income distribution in Japan where foreign trade heavily affects economic conditions.     

Current accounts of Japanese airports

The paper examines the current account of 41 major airports. When we exclude depreciation costs, only seven airports are profitable. When depreciation is excluded, only three airports are making profits. Airports managed by local governments are very difficult to sustain financially without subsidies. Airports with more than 5.2 million passengers are profitable when depreciation is taken into account, however most local airports have fewer than 2.5 million passengers. When depreciation costs are excluded, airports need at least 2.7 million passengers to be viable.     

Organizational dynamics and aggregate fluctuations: The role of financial relationships

This paper constructs an estimated dynamic stochastic general equilibrium model to study the role of labor reallocation between production and organizational tasks within a firm in movements in measured TFP in Japan. Allocating more labor to organizational tasks strengthens the financial relationship with financial intermediaries and helps firms to mitigate a widening in credit spread during financial difficulties. However, doing so reduces the labor allocated to production tasks and hence the measured TFP. Our quantitative analysis indicates that labor reallocation contributes to the observed procyclicality in measured TFP. We also find that this mechanism amplifies and propagates the effects of exogenous shocks on aggregate activity.     

Effect of Exchange Rates and Gasoline Prices on US Imports of Japanese Automobiles

We analyze the effects of gasoline prices and exchange rates on Japanese automobile imports to the United States between 1970 and 2004. We test the relationships before, during, and after the Voluntary Restraint Agreement placed on Japanese imports between 1981 and 1988. We also control for general demand for automobiles and domestically manufactured Japanese vehicles. As expected, we found that demand for Japanese imports is positively correlated with the price of gasoline. Before 1988 the demand for Japanese imports contributed to a strengthening of the yen. But after, a positive relationship between the yen-for-dollar exchange rate and imports has prevailed.     

Tradition and interaction: research trends in modern Japanese industrial history

This paper surveys research findings since the early 1970s, focusing on the growth processes of both traditional and modern industries and their relations with government activity in the period between the 1870s and 1940. Most of the surveyed research can be seen as a response to two theses: first, that pre-1940 Japan was essentially a market-led economy; and second, that the traditional sector did not decline in the industrialisation process, but in fact prospered. The survey argues that there were a good deal of interactions between the modern and traditional sectors at regional levels and that the regional economy occupied a significant place in the ways in which government business relations were structured.     

On the comparison of alternative specifications for money demand: The case of extremely low interest rate regimes in Japan

Using Japanese money market data, this paper compares the predictive ability of the log–log specification with infinite elasticity at a zero interest rate and the semilog specification with a one time switch from moderate to relatively high semielasticity at annual interest rates less than 0.5%. We find that the latter specification dominates the former in terms of predictive ability for the extremely low interest rate regime (the period between 1999 and 2006) because under the former the semielasticity is excessively sensitive to slight changes in interest rates. We find that interest rate semielasticity has remained stable at a high level since the mid-1990s.
