A MICRO-ECONOMIC ANALYSIS OF TEA PRODUCTION USING A SEPARABLE RESTRICTED PROFIT FUNCTION

To derive policy-relevant information, the translog form of a separable restricted profit function was used to model empirically estate tea production in Sri Lanka. Data consisted of 87 observations of prices and quantities for various inputs and outputs from 54 different Sri Lankan tea estates. In different tests, the estimated model respected generally the properties implied by underlying assumptions. Results indicated increasing economies of scale in the factory across the sample and optimal field size to be between 300 and 400 hectares. Amongst estimated short-term elasticities, the supply elasticity of made tea was found to be +0.94.     

Models of International Labor Standards

This article examines existing models of the regulation of international labor standards in the context of international trade. The article first focuses on conceptual and theoretical notions of the international regulation of labor standards. Four existing models of international labor regulations are then examined: the legislative model, the trade sanctions model, the multilateral enforcement model, and the voluntary standards model. The theoretical issues raised and the characteristics of the four models are then used to develop a suggested structure for the international regulation of labor standards in a world of free trade.     

THE INFORMATIONAL CONTENT OF BOND RATINGS

This paper explores the risk structure of interest rates. The focus is on whether yields on industrial bonds indicate that market participants base their evaluations of a bond issue's default risk on agency ratings or on publicly available financial statistics. Using a non-linear least squares procedure, the yield-to-maturity is related to Moody's rating, Standard and Poor's (S&P) rating, and accounting measures of creditworthiness such as coverage and leverage. Market yields are found to be significantly correlated with both the ratings and a set of readily available financial accounting statistics. These results indicate (1) that market participants base their evaluations of an issue's creditworthiness on more than the agencies' ratings and (2) that the ratings bring some information to the market above and beyond that contained in the set of accounting variables. The paper also asks whether the market views Moody's and Standard and Poor's ratings as equally reliable measures of risk or whether the market attaches more weight to one agency's ratings than the other. Finally, the hypothesis that the market pays more attention to the accounting measures and less to the ratings if the rating has not been reviewed recently is tested.     

Building for the future: housing-related sectors and the welsh economy

Since the establishment of the Welsh Assembly Government there has been more emphasis on indigenous enterprises in relation to economic development policy. However, the housing-related sector has received little attention. This paper¹ presents the results of research that has investigated this sector and its significance to the local economy. Whilst acknowledging the considerable data-related difficulties in this exercise, analysis of housing and housing-related functions (including construction, finance, legal services, management of housing stock) showed that the sector accounted for around 4.5% of Welsh employment, and had considerable potential for assisting in the future development of the regional economy.     

PRODUCER TURNOVER AND PRODUCTIVITY GROWTH IN DEVELOPING COUNTRIES

The reallocation of resources, either across sectors or acrossproducers within a sector, can serve as a potential source ofproductivity growth. New research findings exploit comprehensivemicroeconomic data on the manufacturing sectors of Chile, Colombia,and Morocco to document resource shifts as producers enter,expand, contract, and exit operation. The micro-level adjustmentis substantial; between 25 and 30 percent of the total numberof manufacturing jobs turn over each year. In the short run,the productivity effects of this turnover are modest becausethe new plants that come on line are only slightly more productivethan the ones they replace—and both are typically small.In the longer term, however, the turnover generates more substantialincreases in productivity because the new firms that surviverecord substantial productivity gains in their early years.Moreover, firms that exit are typically on a downward productivityspiral and would probably have dragged down sectoral efficiencyfarther if they had continued in operation.      

Without the denominator where is the quality improvement paradigm in the nation's health care reform?

This paper will argue that there is room for improvement in the quality of health care delivered in the United States. A quality improvement paradigm requires an assessment, inventory and prioritization of areas for improvement. It further nurtures the imperative of process improvement for the achievement of a targeted outcome. The dual obligations of reduction in outcome variability, and resource management, provide an exciting milieu for the integration of clinical practice, the numerator, with population based medicine, the denominator.     

The productivity effects of privatization: The case of Polish cooperatives

This paper evaluates the productivity effects associated with privatization of producer cooperatives. The results, based on a sample of 2164 Polish cooperatives, indicate that privatized cooperatives have: (1) 1% lower total factor productivity (TFP) the year prior to privatization and 3-20% higher TFP in the year of privatization and three years post-privatization, (2) 9-36% higher labor productivity, (3) capital productivity effects of − 16-6%. The evidence is consistent with governance and incentive mechanisms of cooperatives being more effective outside of state interference, and with competition and hard budget constraints leading to pressure to restructure and adopt practices that improve productivity.     

Sales force obsolescence: Perceptions from sales and marketing executives of individual, organizational, and environmental factors

The trade and academic literature is replete with observations that many sales organizations are in the midst of a redefinition of the strategic role of their sales forces. With today's market forces, change is overdue in many sales organizations. Consequently, the issue of whether the sales force is becoming obsolete has come to the forefront in recent years. As business environments change rapidly, the relevance of the modern sales force comes into question. Data were gathered from 245 midlevel sales and marketing executives on perceived sales force obsolescence. Our findings suggest that obsolescence is a phenomenon for sales organizations to address. The main findings of our study are (1) obsolescence is a phenomenon that affects sales professionals' feelings toward the job (job satisfaction) and outcomes (performance); (2) a firm's market orientation is very important in lowering perceived obsolescence; (3) a learning orientation is important in detecting symptoms of obsolescence; (4) age and education are related to perceptions of obsolescence depending on the type of industry in which the sales force competes: high- or low-tech; and (5) organizational changes can also have a bearing on the sales force's perceptions of obsolescence.
