An Anatomy of the Productivity Slowdown: Markups, Returns to Scale, and Technical Change in Electric
Utilities in Texas By Subal C. Kumbhakar
This paper considers a profit maximizing model to measure total factor productivity (TFP) growth and decompose it into components attributed to technical change, returns to scale and markups. Technical change is further decomposed into pure, nonneutral, and scale augmenting components. The role of these factors is analyzed in accounting productivity growth of electric utilities in Texas. An interesting feature of the study is the use of panel data on individual electric utilities in Texas during 1966-1985, which covers periods before and after the introduction of statewide regulation. The availability of panel data allows us to model markup behavior over time without imposing any a priori behavior on them. The model also introduces and controls for heterogeneity in the cost structure of the utilities. Empirically we find that markups and TFP growth declined substantially during the year of statewide regulation. In spite of this declining tendancy it is found that markups were the major contributing factor in TFP growth during the entire sample period. Source : Éditeur (via Persée) |
