An impact of efficiency factors on dependence between error components in the stochastic production function model
In the paper technical efficiency of Russian plastic and rubber production firms in 2006–2010 is estimated by SFA. It is demonstrated that increasing firm size will cause increase in its efficiency and also there is increasing returns to scale in the sector. This result is robust for various specifications of the production function and SFA models. Autocorrelation of efficiency estimates is considered as a measure of their persistency.
In literarure there is no single answer to the question, whether the growth of imports in industry leads to decrease or to increase the technical efficiency: possible effect of different mechanisms. In this paper we estimate the stochastic production frontier using firm-level data for food industry in 2005–2011, taking into account a possible relationship between changes in imports and firm’s technical efficiency. We use the «Ruslana» (Bureau van Dijk) database, which contains financial information on companies in Russia. Our results show that in food industry technical efficiency is reducing while import share is increasing.
Paper presents research findings devoted to technical efficiency of banks based on financial reports prepared in accordance with Russian accounting standards (RAS) and international financial reporting standards (IFRS). Key finding is that these estimates vary not only in absolute terms, but also across time and with respect to banks ranks.
