This paper aims at investigating the effects of concentration on competition and cost efficiency of the French audit market. Competition is measured with the Rosse-Panzar model, while cost efficiency is estimated with stochastic frontier approach. Cost efficiency levels are estimated at around...

This paper investigates whether financial intermediary development influences macroeconomic technical efficiency on a sample of 47 countries, both developed and developing, over 1980-1995. We do so by applying Battese and Coelli (1995)’s method at the aggregate level. It is found that...

This paper investigates the timing of the impact of changes in checks and balances on macroeconomic efficiency in a panel of countries. Using Battese and Coelli’s one-stage approach, we find that increasing checks and balances results in greater efficiency. Furthermore, the impact of...

This paper tests whether corruption may be an efficient grease in the wheels of an otherwise deficient institutional framework. It analyzes the interaction between aggregate efficiency, corruption, and other dimensions of governance for a panel of 69 countries, both developed and developing....

We analyze how adding the shadow economy to official output figures affects estimated technical efficiency at the country level. We find that this only slightly affects the ranking of efficiency scores, but increases average efficiency in a sample of 87 to 97 countries, both developed and...
