This paper investigates empirically the relationship between firm size and production efficiency, and the relationship between firm size and the likelihood of paying bribes using firm-level data from Vietnam. Our analysis indicates that middle-sized firms’ production efficiencies tend to...

This paper develops two cost decompositions based on the multiplicative and additive Russell efficiency measurement framework. While the multiplicative cost decomposition is a straightforward extension of the standard cost decomposition, the decomposition we develop in this paper incorporates...

Recently Diewert (2014) decomposed cost change into the product of four drivers. He then combined three of these drivers with a novel measure of returns to scale to decompose profitability change. We use an implicit Konus input quantity index to show that his expression for profitability change...

Diversified and focused business models may affect foreign bank efficiency differently. We investigate whether there is an optimal business model along three business dimensions—assets, funding and income—and which business model is optimal for foreign banks in a financial center....

Adopting a profit-based approach to the estimation of the technical efficiency of South Korean banks over the 2007Q3 to 2011Q2 period, we systematically analyse, within a non-parametric DEA analysis, how the choice of risk management control variable impacts upon such estimates. Using the model...

The banking sector plays a major role in any economy, and it played a critical role in transition of Ukraine to a market economy. In this work, we investigate the hypothesis that, despite the tremendous growth and apparent prosperity that existed before the country was hit by the global...

When analyzing productivity and efficiency of firms, stochastic frontier models are very attractive because they allow, as in typical regression models, to introduce some noise in the Data Generating Process. Most of the approaches so far have been using very restrictive fully parametric...

This paper uses a relatively new total factor productivity (TFP) index to measure productivity change in the Australian economy. Unlike the TFP indexes used by most statistical agencies, the index used in this paper satisfies a suite of common sense axioms from index number theory. It can also...

In this paper we consider the problem of aggregation of Hicks-Moorsteen productivity indexes. The aggregate indexes are derived in a manner which is justified by economic theory, consistent with previous aggregation results, and maintains analogous decompositions to the original measures. These...
