Corporate governance quality: Trends and real effects

This paper constructs a composite index of corporate governance quality, documents its evolution during the 1994–2003 period in selected emerging and developed economies, and assesses its impact on growth and productivity of the economy and its corporate sector. Our investigation yields three main findings. First, corporate governance quality in most countries has overall improved, although in varying degrees and with a few notable exceptions. Second, the data exhibit cross-country convergence in corporate governance quality with countries that score poorly initially catching up with countries with high corporate governance scores. Third, the impact of improvements in corporate governance quality on traditional measures of real economic activity—GDP growth, productivity growth, and the ratio of investment to GDP—is positive, significant and quantitatively relevant, and the growth effect is particularly pronounced for industries that are most dependent on external finance.     

Multiple influences on corporate governance practice in Nigeria: Agents,strategies and implications

The literature on the convergence of corporate governance systems across different institutional contexts has often taken the role of ‘agents of convergence’ for granted. Against this background, we examine the influences of three major agents – international organisations, rating agencies, and local institutions – on the development of corporate governance practices in Nigeria. Findings indicate that the understanding and practice of corporate governance in Nigeria are in a flux and being pulled in multiple directions by the agents studied. This paper provides one of the very few studies utilising sub-Saharan African (Nigerian) data in international business governance research.     

Monetary policy with sticky prices and segmented markets

Summary. We consider a sticky-price model with segmented asset markets, and examine its implications for monetary policy. Our finding is, first, that the response of the money supply growth rate to a money demand shock required to stabilize inflation is not affected by the existence of a liquidity effect, but the response of the nominal interest rate is. Second, when the monetary authority adopts a Taylor rule, whether or not it should be active to obtain local determinacy of equilibria depends on the existence of a liquidity effect. Our results suggest that the monetary authority should be careful about the existence and the degree of a liquidity effect particularly when the nominal interest rate is used as the policy instrument.Received: 11 February 2004, Revised: 1 November 2004 JEL Classification Numbers: E3, E4, E5.     

Total Labour Requirements and Value Added Productivity of Labour in the Process of Economic Development

When the inverse of the value added productivity of labour is regressed on total labour requirements (which is equivalent to labour values), a significant relationship is obtained. This indicates that the value added productivity of labour can be explained by total labour requirements (labour values). The mean value of the regression coefficients is about 1.7. The regression coefficients have a tendency to increase during the process of rapid economic development and to decrease afterwards. Such movements are explained by value added linkages. This study is based on input–output analysis, where total labour requirements per monetary unit of output and the value added productivity of labour are calculated for each of 24 industries in Japan, Korea and USA, every 5 years between 1960 to 1985.     

Returns to scale: concept,estimation and analysis of Japan's turbulent 1964–88 economy

Abstract There is policy interest in factoring productivity growth into technical progress and returns to scale components. Our approach uses exact index number methods to reduce the parameters that must be estimated, and allows us to exploit the cross‐sectional dimension of plant‐level panel data. We show that the same equation can also be used to estimate ‘Harberger’ scale economies and technical progress indicators that require fewer assumptions. Estimates of the elasticity of scale for Japanese establishments in three major industries over 1964–88 are presented. Our study spans the high growth era of the 1960s, two oil shocks, and other exogenous shocks.     

The residential demand for electricity in Japan: An examination using empirical panel analysis techniques

This paper examines the residential demand for electricity in Japan, excluding Okinawa-prefecture, from 1975 to 2005 as a function of the disposable income per household and the overall unit price of electricity for general consumers, by using the empirical panel analysis techniques of a panel unit root test, a panel cointegration test, and group-mean dynamic ordinary least squares (DOLS) estimators to determine whether or not each variable is stationary. This study's contribution is twofold. First, for a more accurate empirical economic analysis, it divides Japan into a number of regions so that the estimation of coefficients becomes more powerful due to the increased degree of freedom from the utilization of the panel data. Second, the study chose Japan for this analysis on the basis of discussions regarding the deregulation of the residential electric power supply that is scheduled for the near future. All variables—sales per household, price, and income per household—can be assumed to have a unit root and cointegration relationship. The results determine that the price effect is negative and elastic and that the income effect is inelastic. These results correspond to other such studies on developed countries that are significant economic powers.
