Effect of agglomeration on technical efficiency of small and medium‐sized garment firms in Egypt

This study investigates the effect of agglomeration on technical efficiency of small and medium‐sized garment firms in Egypt. Using a sample of 502 firms, we estimated a translog stochastic frontier production function with inefficiency components. We also applied a switching regression model to address self‐selection in choice of agglomeration. Results confirm that agglomeration enhances technical efficiency of sampled firms through development of industrial linkages and accumulation of human capital. Given the increasing importance of cluster‐based development policies, we underscore the need to promote agglomeration of garment firms, and thereby foster forward and backward linkages to improve their efficiency and to develop global value chains.     

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.     

WELFARE GAINS FROM FINANCIAL LIBERALIZATION*

Financial liberalization has been a controversial issue, as empirical evidence for growth enhancing effects is mixed. Here, we find sizable welfare gains from liberalization (cost to repression), although the gain in economic growth is ambiguous. We take the view that financial liberalization is a government policy that alters the path of financial deepening, whereas financial deepening is endogenously chosen by agents given a policy and occurs in transition toward a distant steady state. This history‐dependent view necessitates the use of simulation analysis based on a growth model. Our application is a specific episode: Thailand from 1976 to 1996.     

Strategic safety stock placement in supply chain design with due-date based demand

We present a strategic safety stock placement model in supply chain design for assembly-type product with due-date based demand, where demand data are based on dates when company has to ship to customers rather than order receiving dates. We formulate multi-echelon stock placement by guaranteed-service model with demand propagation equations through backward explosion, where demand can be either stationary or nonstationary. The stock placement model is incorporated into network design problem and its optimization procedure is provided. We show effectiveness of the optimization procedure and other significant features of the model through numerical examples of a machinery product supply chain.     

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.     

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.     

Unfunded pension liabilities and stock returns

This paper investigates whether the market rationally anticipates the value implications of unrecognized pension obligations, using a large sample of Japanese firms where pension obligations are substantially underfunded. If a firm's unrecognized pension obligation is not incorporated into its share price, its stock returns will be lower than those of other firms, because its deficit will affect the firm's income statement in the coming years. We find that firms with large unrecognized obligations earn lower risk-adjusted returns. This evidence suggests that the market does not efficiently incorporate information in the pension items.     

Emission Allowance as a Derivative on Commodity-Spread

We provide a valuation formula for emission allowance. Assuming that the value of emission allowance on the last day of a trading phase is equal to a spread of commodity prices (e.g. electricity and natural gas) when the spread is positive and less than the penalty, we show that the emission allowance price is equal to the value of a portfolio of European call options on the spread of the commodities. Using the formula, we obtain a hedging strategy for emission allowance trading. We also empirically analyze option value embedded in emission allowance, and find by numerical analysis that the option value is relatively large.     

BUSINESS CYCLES IN THE EQUILIBRIUM MODEL OF LABOR MARKET SEARCH AND SELF‐INSURANCE*

I introduce risk‐aversion, labor‐leisure choice, capital, individual productivity shocks, and market incompleteness to the standard model of labor search and matching and investigate the model’s cyclical properties. I find that the model can generate the observed large volatility of unemployment and vacancies with a reasonable replacement rate of unemployment insurance benefits of 64%. Labor‐leisure choice plays a crucial role through additional utility from leisure when unemployed and further amplification from adjustments of hours worked. On the other hand, the borrowing constraint or individual productivity shocks do not significantly affect the cyclical properties of unemployment and vacancies.     

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.
