We extend the analysis of Campbell et al. (1993) on the relationship between the first-order daily stock return autocorrelation and stock market trading volume by allowing abrupt and smooth transition structures using lagged stock returns as a transition variable. Using U.S. stock market data,...

This paper examines whether trade credit as a credible signal about firmfs creditworthiness to banks facilitates provision of bank credit to the firms receiving trade credit. Using data on Japanese manufacturing firms over the period 1990-1995, we find that firms receiving trade credit are...

Research was conducted concerning the effects of child support. Many earlier studies have assumed full employment. However, in the real economy, there is unemployment. The relation between the number of children in the economy and unemployment was investigated. The overlapping generation model...

To investigate how fertility rates interrelate with the modern economy, we construct a simple model in which variety expansion of consumption goods reduces fertility rates. In our model, variety expansion reduces the relative price of a composite of differentiated goods compared to child-...

This paper explores the mutual reference behavior of local governments in Japan. The Japanese public education system was decentralized in the previous decade. For example, actual fixed number of classes was relaxed in 2001 and 2003. This relaxation of regulations caused an increase in the...

In this paper, we develop an endogenous growth model with two coun- tries in which the international trade of differentiated goods requires dif- ferent trade costs and equilibrium wages in the two countries. If the labor productivity in one country's agricultural sector is higher than that of...

The Bank of Japan adopted the Quantitative Easing (QE) Policy from March 2001 to March 2006. This paper investigates whether or not this QE had an effect in stimulating real economy in Japan. The identification of policy effect in the above Japanese case enables us to evaluate indirectly the...

With the data of 831 Japanese water utilities from 1999 to 2008, we used the stochastic cost frontier analysis with a true fixed-effect model in order to estimate the cost efficiency and scale economies. We found that cost inefficiency was approximately 37%. The economies of water delivery...

This paper presents a welfare analysis of free entry equilibrium in dynamic general equilibrium environments with oligopolistic competition. First, we show that a marginal decrease in the number of firms at the free entry equilibrium improves social welfare. Second, we show that if a government...

This paper develops a simple search model in which sector-specific trainings are endogenously determined with or without a negotiation between a worker and an employer, and characterizes the allocation of two types of training. If a worker and an employer can negotiate over the amount of skill...
