This paper constructs an endogenous growth model with overlapping generations, whose engine of economic growth is productive public capital. The government faces a trade-off in public policy between public investment and social security provision because of its budget constraint. Larger public...

How many members should committees consist of? This paper addresses this question in view of imperfect information and coordination behavior among the members, which is a new approach alternative to introducing information acquisition cost. First, using a simple model, I show that the existence...

The objective of this paper is to examine effects of realized covariance matrix estimators based on intraday returns on large-scale minimum-variance equity portfolio optimization. We empirically assess out-of-sample performance of portfolios with different covariance matrix estimators: the...

The welfare effects of capital market integration are examined under a model of tax competition with two asymmetric countries. The asymmetry is expressed through the labor market: one country has a perfect labor market whereas the other country is unionized. Our results show that the welfare...

Water production and service quality have been used as dimensions of efficiency evaluation in previous studies of water utilitiesf performance. This study attempts to show that the inclusion of water purification efforts should be another crucial dimension in the efficiency measurement. We use a...

This paper focuses on the involvement of Siemens on the market for radiology equipment in Japan between 1900 and 1960 from a business history perspective. It explores why the German multinational was unable to keep its dominant position on the Japanese market in the interwar years, despite its...

Recently, as low birth rates and the aging of society have intensified, considerable analysis is being conducted using overlapping generations models with endogenous birth rates. However, most previous studies have assumed full employment. Since it is the case that unemployment does exist in...

The life cycle/permanent income hypothesis (LCPIH) makes two postulates: people behave with rational expectations, and people do not have self-control problems. If either or both of these postulates do not apply, we cannot obtain a testable implication of the LCPIH. We use Japanese panel data...

This paper analyzes intraday volatility of the stock markets of mainland China, Hong Kong, Japan, and the US for the period of two months around the Lehman crisis. Specifically, dividing the observation period from July 15 to November 28, 2008 into two sub-periods at the failure of Lehman...

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,...
