How Fast Do Banks Adjust? A Dynamic Model of Labor-Use with an Application to Swedish Banks 总被引:1,自引:0,他引:1
Kumbhakar Subal C. Heshmati Almas Hjalmarsson Lennart 《Journal of Productivity Analysis》2002,18(1):79-102
This paper deals with a dynamic adjustment process in which adjustment of a key variable input (labor) towards its desired level is modeled in a panel data context. The partial adjustment type model is extended to make the adjustment parameter both firm- and time-specific by specifying it as a function of firm- and time-specific variables. Desired level of labor use is represented by a labor requirement function, which is a function of outputs and other firm-specific variables. The catch-up factor is defined as the ratio of actual to desired level of employment. Productivity growth is then defined in terms of a shift in the desired level of labor use and the change in the catch-up factor. Swedish banking data is used as an application of the above model. 相似文献

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.

This paper draws attention for the fact that traditional Data Envelopment Analysis (DEA) models do not provide the closest possible targets (or peers) to inefficient units, and presents a procedure to obtain such targets.It focuses on non-oriented efficiency measures (which assume that production units are able to control, and thus change, inputs and outputs simultaneously) both measured in relation to a Free Disposal Hull (FDH) technology and in relation to a convex technology. The approaches developed for finding close targets are applied to a sample of Portuguese bank branches. 相似文献

地下管线的主要特点是隐蔽性,地下分布纵横交错,年代已久的原有手工数据几乎无参考价值且存档不便、使用复杂、工作量大。使用自主开发升级后的计算机程序软件,不仅可以大大提高地下管线测量数据的更新、规划设计及施工的效率,而且可以通过CAD图形分析对特殊地段重要管线是否保留利用作出决定。 相似文献

Improving productive efficiency is an increasingly important determinant of the future of the swine industry in Hawaii. This paper examines the productive efficiency of a sample of swine producers in Hawaii by estimating a stochastic frontier production function and the constant returns to scale (CRS) and variable returns to scale (VRS) output-oriented DEA models. The technical efficiency estimates obtained from the two frontier techniques are compared. The scale properties are also examined under the two approaches. The industry's potential for increasing production through improved efficiency is also discussed. 相似文献

This paper utilizes the average derivative estimation of Stoker (1986) and the pesudo-likelihood estimation of Fan, Li, and Weersink (1996) to estimate a semiparametric stochastic frontier regression, y = g(x) + , where the function g(.)is unknown and is a composite error in a standard setting. The proposed semiparametric method of estimation is applied to data on farmers' credit unions in Taiwan. Empirical results show that the banking services of the farmers' credit unions is subject to economies of scale, but high degree of cost inefficiency in operation. 相似文献

《萨班斯法案》的出台堪称注册会计师行业的一件大事,从理论上看,该法案各项条款的出台确实具有积极的意义,但仍然存在缺陷,它更多地强调监管的作用,而监管的效率往往不如制衡的效率;它更多地强调经济处罚和刑事处罚的作用,而这两种处罚却必须以民事赔偿为前提,并最终使作假行为的作假成本大大高于作假收益。 相似文献
