Duality methods of linear and convex programming are applied to impute definite marginal values to the fixed inputs of a hydroelectric plant from the operating profit. Our earlier analysis of pumped storage (of energy and other cyclically priced goods) is thus extended to valuation of an...

We apply duality methods of linear and convex programming to the problems of operation and rental valuation of facilities for conversion and storage of cyclically priced goods, e.g. , energy. Both problems are approached by shadow-pricing the stock (which is a purely intermediate commodity); and...

This paper develops an empirical model of entry to analyze the effect of previous regulation on European airlines? post-liberalization profits. The author distinguishes between European flag carriers, which are hightly regulated at the beginning of the eighties, and independent airlines. It is...

The paper specifies and estimates a production function for the airline industry, identifying firms' network characteristics and efficiency as the main determinants of their productivity. The application of this analysis to the European market shows that productivity differences among flag...

Sample coordination maximizes or minimizes the overlap of two or more samples selected from overlapping populations. It can be applied to designs with simultaneous or sequential selection of samples. We propose a method for sample coordination in the former case. We consider the case where units...

Contingency formulations of Human Resource Management (HRM) theory suggest that the effectiveness of HRM practices should vary across firms. This study examined whether the relationship between HRM practices and productivity in manufacturing companies is contingent upon organizational climate...

Most accounts of business coordination assume historically given conditions for this to emerge. Business coordination is therefore difficult, perhaps impossible, to construct endogenously. This paper examines a process of ‘endogenous coordination’ through an analysis of reindustrialization...

Using detailed edit-level data over eight years across a large number of articles on Wikipedia, we find evidence for a positive spillover effect in editing activity. Cumulative past contributions, embodied by the current article length, lead to significantly more editing activity, while...

This paper compares centralized and decentralized coordination when managers are privately informed and communicate strategically. We consider a multidivisional organization in which decisions must be adapted to local conditions but also coordinated with each other. Information about local...

Consistent with a growing number of models about affect and behaviour and with a recognition that perception alone provides no impetus for action, it was predicted that associations between company climate and productivity would be mediated by average level of job satisfaction. In a study of 42...
