This study demarcates cost-inefficiency in Chinese banks into X-inefficiency and rent-seeking-inefficiency. 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...

This paper examines the impact of financial sector reforms on the cost structure characteristics and on t...

Does BPO pay off at the firm-level? Although there are several studies which analyze the potential benefits of BPO, there is a virtual absence of research papers on BPO outcomes. Based on an analysis of 137 Business process outsourcing (BPO) ventures at 254 German banks in a period between 1994 and 2005, we found that the outsourcer’s financial performance in terms of profitability and cost eff...

Economic models for reuse can help managers to forecast the benefits of a reuse investment before committing any resources. In this paper, we propose a Software Cost Estimation Model for Product Line Engineering (SoCoEMo-PLE). In fact, PLE approaches to software development seem to be very attractive in matter of product quality and time-tomarket. Thus, we need an economic model to quantify the...
