Abstract Most soybean farming in Indonesia is still performed conventionally. Farmers are less interested cultivating soybeans because the production yields relatively small. This research aims to determine factors influencing production, inefficiency of soybean, and technical efficiency (TE) economic (EE) level farming. Primary data were collected using a survey method farmers paddy field area...

This paper presents a methodology for estimating an index of technological change using firm-level data in a stochastic frontier production function model that takes into account time-varying technical inefficiency. In contrast to the Solow divisia index approach, econometric estimation of the index with panel data allows the researcher to separate technical progress from the stochastic measure...
