This paper estimates dynamic efficiency in the Spanish construction industry before and during the current financial crisis over the period 2001-2009. Static efficiency measures are biased in a context of a significant economic crisis with large investments and disinvestments as they do not account for costs in the adjustment of quasi-fixed factors. The results show that overall dynamic cost in...

This study demarcates costinefficiency in Chinese banks into X-inefficiency and rent-seekinginefficiency. A protected banking market not only encourages weak management and X-inefficiency but also public ownership and state directed lending encourages moral hazard and bureaucratic rent seeking. This paper uses bootstrap non-parametric techniques to estimate measures of X-inefficiency and rent-s...

The price of anarchy [16] is by now a standard measure for quantifying the inefficiency introduced in games due to selfish behavior, and is defined as the ratio between the optimal outcome and the worst Nash equilibrium. However, this notion is well defined only for games that always possess a Nash equilibrium (NE). We propose the dynamic inefficiency measure, which is roughly defined as the av...

The existing Chinese banking system was born out of a state-planning framework focussed on the funding of state-owned enterprises. Despite the development of a modern banking system, numerous studies of Chinese banking point to its high level of average inefficiency. Much of this inefficiency relates to the high level of non-performing loans held on the banks books. This study argues that a sig...

This study empirically examines the association between hospital inefficiency and the decision to introduce electronic medical records (EMR) and computerized physician order entry (CPOE) in a national sample of U.S. general hospitals in urban areas in 2006. The main research question is whether the presence of hospital cost inefficiency or other factors driving inefficiency in the production pr...

We present a new DEA based method to analyze efficiency trends over time and differences across subgroups in a panel data setting. We employ a result that the aggregate technical and allocative inefficiency score equals the technical inefficiency when input quantities are aggregated into a single total input cost variable, and develop test procedures to evaluate the presence of allocative ineff...

Large applications often suffer from excessive memory consumption. The nature of these heaps, their scale and complex interconnections, makes it difficult to find the low hanging fruit. Techniques relying on dominance or allocation tracking fail to account for sharing, and overwhelm users with small details. More fundamentally, a programmer still needs to know whether high levels of consumption...

in this research the activity of 75 producers, 55 wholesalers and 55 retailers, citrus market of jahrom county was investigated. the results indicated that margin of wholesale, retail and total margin of citrus in this county was 1461.1, 1480.3, and 2941.4 rs respectively. share of producer from marginal price was estimated to be 57.9 percent and share of wholesaler was more than retailer. in t...

There have been many previous studies of technical inefficiency in rice production in the Philippines, but none has focused simultaneously on production risk and technical inefficiency at the farm level. In this study, we analyse technical inefficiency in a rainfed lowland rice environment in Central Luzon using a stochastic frontier production function with a heteroskedastic error structure.
