This statement is divided into three parts: • Brief overview on the Bulgarian Pension Reform – the stages of its implementation; the main features of the reform and development of Pension funds in the country; • Describing pension funds investments regulation almost 9 years after the beginning of the pension reform; amendments of pension legislation related to investments of pension funds assets; • The last part consists of the main forthcoming changes in regulation and I will try to make some concluding comments.

  Algorithm for Econometric Estimation of the Aggregated Production Function by Transcendental Logarithmic (translog) Approximation

  The study analyzes the dependence of gross domestic product of the number of employees and gross fixed capital formation in Bulgaria with the help of the aggregate production function. Based on quarterly data, which covered the first quarter of 1996 to the first quarter of 2007, is examined the elasticity of substitution of production factors. It ... The study analyzes the dependence of gross domestic product of the number of employees and gross fixed capital formation in Bulgaria with the help of the aggregate production function. Based on quarterly data, which covered the first quarter of 1996 to the first quarter of 2007, is examined the elasticity of substitution of production factors. It is tested three types of production functions – a production function with variable elasticity of substitution of factors (VES-function), a production function with constant elasticity of substitution of factors (CES-function) and classical Cobb-Douglas function. Estimates of the parameters were obtained with the least squares method, applied to transcendental logarithmic (translog) approximation of the production function.
