- This paper deals with modeling firm-specific technical change (TC), and technological biases (inputs and scale) in estimating total factor productivity (TFP) growth. Several dual parametric econometric models are used for this purpose. We examine robustness of TFP growth and TC among competing models. These models include the traditional time trend (TT) model and the general index (GI) model. The TT and the GI models are generalized to accommodate firm-specific TC and technological bias (in inputs and output). Both nested and non-nested tests are used to select the appropriate models. Firm-level panel data from the Japanese chemical industry during 1968- 1987 is used as an application.

Estimation of productivity in Korean electric power plants : A semiparametric smooth coefficient model

Tidskriftsartikel (refereegranskat)abstract
- This paper analyzes the impact of load factor, facility and generator types on the productivity of Korean electric power plants. In order to capture important differences in the effect of load policy on power output, we use a semiparametric smooth coefficient (SPSC) model that allows us to model heterogeneous performances across power plants and over time by allowing underlying technologies to be heterogeneous. The SPSC model accommodates both continuous and discrete covariates. Various specification tests are conducted to assess the performance of the SPSC model. Using a unique generator level panel dataset spanning the period 1995-2006, we find that the impact of load factor, generator and facility types on power generation varies substantially in terms of magnitude and significance across different plant characteristics. The results have strong implications for generation policy in Korea as outlined in this study. (C) 2014 Elsevier B.V. All rights reserved.

Estimation of technical change and TFP growth based on observable technology shifters
- 2020

Ingår i: Journal of Productivity Analysis. - : Springer. - 0895-562X .- 1573-0441. ; 53:1, s. 21-36

Tidskriftsartikel (refereegranskat)abstract
- This paper models and estimates total factor productivity (TFP) growth parametrically. The model is a generalization of the traditional production function model where technology is represented by a time trend. It decomposes TFP growth into an unobservable time trend induced technical change, scale economies and an observable technology shifter index's components. The empirical results are based on unbalanced panel data at the global level for 190 countries observed over the period 1996-2013. It uses a number of exogenous growth factors in modeling four technology shifter indices to explore development infrastructure, finance, technology and human development determinants of TFP growth. Our results show that unobservable technical change remains the most important component of TFP growth. Our findings also show that technical changes and TFP growth are unexpectedly negative across all country income groups and years.

Estimation of technical efficiency in Swedish crop farms : A pseudo panel data approach
- 1997
-
Ingår i: Journal of Agricultural Economics. - 0021-857X .- 1477-9552. ; 48:1, s. 22-37
-
Tidskriftsartikel (refereegranskat)abstract
- This paper deals with the estimation of technical efficiency using pseudo panel data constructed from rotating panel data on Swedish crop farmers where each unit is observed for a maximum of four years. Farms are grouped into 89 cohorts, using their common time-invariant characteristics, and the cohorts are used as an individual unit in the empirical analysis. The overall technical inefficiency is decomposed into a persistent and a residual component. An alternative model with time-varying technical inefficiency is also considered. In addition to technical inefficiency, measures of returns to scale and technical change are also obtained.

Farm heterogeneity and technical efficiency : Some results from Swedish dairy farms
- 1994
-
Ingår i: Journal of Productivity Analysis. - 0895-562X .- 1573-0441. ; 5:1, s. 45-61
-
Tidskriftsartikel (refereegranskat)abstract
- This paper introduces farm-heterogeneity in measuring technical efficiency of Swedish dairy farms using farm-level data. In calculating technical efficiency which is allowed to vary over time and across farms, we control for farm-specific effects. This is possible only when panel data is available. Furthermore, we separate technical efficiency from technical change-the presence of which is indicated by a shift in the production function over time, ceteris paribus. We also calculate percentage change in technical efficiency to examine whether farm efficiencies have improved over time. Finally, a comparison of technical efficiency, elasticities of different inputs, and technical change is made across different years and panels. The data includes four panels of dairy farms observed during the period 1976-1988, excluding 1985. ©1994 Kluwer Academic Publishers.

Fiscal policy and inclusive growth in advanced countries : Their experience and implications for Asia
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This study seeks to draw relevant lessons from the advanced economies for developing Asia in using fiscal policy to tackle inequality. The experience of the advanced economies clearly shows the sizable equity-promoting potential of fiscal policy. At the same time, developing Asia’s pursuit of more inclusive fiscal policy must not come at the expense of economic growth or fiscal sustainability.
