Modeling Technical Change: Theory and Practice

Abstract:
Abstract This chapter focuses on models dealing with technical change (TC). We discuss TC under both single output and multiple outputs cases. For the single output case, we specify the technology in terms of a (i) production (input or output distance) function, (ii) cost function, and (iii) profit function. Each of these cases is discussed under disembodied approaches, which are not associated with a specific input and embodied (factor-augmenting (FA)) approaches, which are specific to input(s). In the disembodied approach, we mostly focus on time driven TC which includes models with the time trend and general index approaches. First, we discuss each of the cases in a standard neoclassical setup without technical inefficiency followed by a brief discussion of some of the models with technical inefficiency. We also discuss TC and total factor productivity (TFP) in models with good and bad outputs. Finally, we link TFP change with profitability change.
