This paper establishes a new metafrontier directional technology distance function (MDDF) under a stochastic framework, rather than a deterministic setting like the one proposed by Battese et al. (2004). The new MDDF allows for calculating comparable technical efficiencies for banks under...

In the majority of production processes, noticeable amounts of bad byproducts or bad outputs are produced. The negative effects of the bad outputs on efficiency cannot be handled by the standard Malmquist index to measure productivity change over time. Toward this end, the Malmquist–Luenberger...

Following the spirit of the enhanced Russell graph measure, this paper proposes an enhanced Russell-based directional distance measure (ERBDDM) model for dealing with desirable and undesirable outputs in data envelopment analysis (DEA) and allowing some inputs and outputs to be zero. The...

The focus of this paper is on the productive efficiency of ports. We estimate a directional technology distance function using parametric techniques to analyze the production technology and technical efficiency of a set of Spanish Port Authorities observed over the period 1993–2012. Technical...

The typical school district in the US consists of a central office overseeing primary, middle and high schools. The school district budget is allocated between the central administration and the constituent schools, who can spend these funds on personnel and non-personnel. We model this...

This article studies the role of social capital on cotton production efficiency and productivity for a sample of small farms in Maharashtra, India using data envelopment analysis. Input shadow prices are computed as an indicator of the importance of social capital relative to other inputs....

The paper contributes to the contemporary research on bank efficiency in India. We analyze the efficiency dynamics of the Indian banking industry from 2004 to 2012. Based on the recent methodological developments of the conditional and unconditional directional distances introduced by Daraio and...
