This study measures the status of technical efficiency of companies in Dhaka stock exchange (DSE) for panel data using the stochastic frontier production function, incorporating technical inefficiency effect model. For this study, we used the data collected from DSE market consisting 94 companies in Bangladesh for the period of 2000 to 2008.
