Are some Indian banks too large? An examination of size efficiency in Indian banking 总被引:1,自引:0,他引:1
Subhash C. Ray 《Journal of Productivity Analysis》2007,27(1):41-56
In this paper we use data from the years 1997–2003 to evaluate the size efficiency, as distinct from scale efficiency, of
Indian banks. Following Maindiratta [Maindiratta A (1990) J Econ 46:39–56] we consider a bank to be “too large” if breaking
it up into a number of smaller units would result in a larger output bundle than what could be produced from the same input
by a single bank. When this is the case, the bank is not size efficient. Our analysis shows that many of the banks are, indeed,
too large in various years. We also find that often a bank is operating in the region of diminishing returns to scale but
is not a candidate for break up.

Reduction of risk of occupational injuries is one of the most challenging problems faced by industry. Assessing and comparing risks involved in different jobs is one of the important steps towards reducing injury risk. In this study, a comprehensive scheme is given for assessing and comparing injury risks with the development of injury count model, injury risk model and derived statistics. The hazards present in a work system and the nature of the job carried out by workers are perceived as important drivers of injury potential of a work system. A loglinear model is used to quantify injury counts and the event-tree approach with joint, marginal and conditional probabilities is used to quantify injury risk. A case study was carried out in an underground coal mine. Finally a number of indices are proposed for the case study mine to capture risk of injury in different jobs. The findings of this study will help in designing injury intervention strategies for the mine studied. The job-wise risk profiles will be used to prioritise the jobs for redesign. The absolute indices can be applied for benchmarking job-wise risks and the relative indices can be used for comparing job-wise risks across work systems. 相似文献

As product offerings of multinational enterprises (MNEs) continue to primarily serve the relatively well-to-do consumers in emerging economies, innovations to meet the unique affordability and acceptability criteria of masses at the base of the pyramid (BoP) continues to remain a daunting challenge. The academic literature is sparse on comprehensive in-depth studies about the intricate processes involved in shaping and managing technology development for the masses. Focusing on product innovation by Tata Motors of India with the Nano—the world's cheapest car, our case study aims to understand how the innovator's choices regarding the use of technology, product design and organizational practices for new product development enabled it to meet the challenge of innovation for India's masses. Drawing on Christensen's work on disruptive innovations, our analysis shows how frugal use of resources through a new combination of existing component technologies created a new modular product to achieve the unique price–performance requirements demanded by the BoP. Our findings show that collaboration with suppliers for component design and their early integration in the design phase substantially lowered costs and helped eliminate unnecessary frills whilst incorporating features valued by mass markets. Our study has important managerial implications for MNEs and provides critical insights into the processes for a new blueprint for an untapped market segment in the automobile industry. 相似文献

In a two‐country model where firms behave à la Cournot, we show that trade liberalization increases (decreases) the social desirability of those mergers that generate sufficiently large (small) reductions in marginal cost. There exists a range of intermediate levels of marginal cost savings such that marginal tariff reductions increase (decrease) the desirability of merger at sufficiently low (high) tariff levels. Moreover, in the neighborhood of free trade, we show that if trade liberalization increases the profitability of a merger, it necessarily also increases its desirability. 相似文献

We consider economies and diseconomies of scope for large U.S. banks by employing ordinary and hybrid translog cost functions. We examine the regularity conditions in output space where scope estimates are calculated and reject all models for which these conditions fail. The translog model always possesses violations. For the hybrid translog, violations occur in every case except one. In this one case, we find economies of scope. 相似文献

The unitary household model implies pooling of all individual incomes. This study distinguishes between various types of income pooling and tests them on Australian household income/expenditure data. The tests recognise the endogeneity of both earned and unearned income and are performed using a 3 SLS estimation procedure that allows feedback between the various equations. The results support income pooling for some items, though not for others. Moreover, income pooling across gender seems much less likely for old people than for the younger individuals. The study, also, provides evidence on the interaction between the various types of income. 相似文献
