Capital Labour Substitution in the Large-scale Food-processing Industry in Pakistan: Some Recent Evidence
Food-processing is one of the first industries developed by man. Most agricultural commodities require some sort of processing for them to be edible. In primitive societies man processed his own food using the simple mortar and pestle. With the advent of industrialisation there emerged important implications for foodprocessing technologies. The workers in the industrial and commercial sectors of urban areas required greater supplies of food. This encouraged the establishment of processing plants supplemented by storage facilities to ensure that the urban population received the food that they required. Food-processing, therefore, began to occupy a fairly predominant position in the overall industrial sector. Its importance was heightened by its strong backward and forward linkages with the rest of the economy. In a labour-surplus developing economy, where most of the labour is unemployed or underemployed, the absorption of this surplus labour force in the industrial sector is an important issue. In recent decades, there has been significant growth in the industrial sector in most developing countries, in terms of both
IDENTIFICATION AND ESTIMATION OF ELASTICITIES OF SUBSTITUTION FOR FIRM-LEVEL PRODUCTION FUNCTIONS USING AGGREGATIVE DATA
Firm-level stochastic CES and YES production functions are defined and conditions are specified such that elasticities of substitution can be identified and efficiently estimated from aggregative data on firms within different asset-size categories. Attention is given to the estimation of production functions using cross-sectional and time-series data. The sufficient conditions specify that levels of factors of production be the same for firms within designated categories.
Deliberative Democracy and the Resource Curse: A Nationwide Experiment in Tanzania
Oil and gas discoveries in developing countries are often associated with short-sighted economic policies and, in response, calls to insulate resource management from populist impulses. We report on a randomized experiment testing methods to overcome this apparent tension between sound resource governance and democratic politics. Soon after Tanzania’s discovery of major natural gas reserves, we invited a nationally representative sample of voters to an intensive public deliberation of policy options featuring nationally recognized experts and small-group discussions. Democratic deliberation reinforced the public’s strong preference for rapid spending of gas revenues, but also increased support for various prudential and economically orthodox measures, including independent oversight of gas revenues, limits on government borrowing, and selling gas abroad rather than subsidizing fuel at home. These effects were driven by deliberation per se, rather than a pure information treatment, and show no evidence of contamination by facilitatoror peer-effects in group deliberations. www.cgdev.org Justin Sandefur, Nancy Birdsall, James Fishkin, and Mujobu Moyo
