Effects of Some Selected Variables on Rice-Farmers Technical Efficiency

One-Step and Two-Step Estimation of the Effects of Exogenous Variables on Technical Efficiency Levels

Consider a stochastic frontier model with one-sided inefficiency u, and suppose that the scale of u depends on some variables (firm characteristics) z. A “one-step” model specifies both the stochastic frontier and the way in which u depends on z, and can be estimated in a single step, for example by maximum likelihood. This is in contrast to a “two-step” procedure, where the first step is to es...

On the Ratio of Rice Random Variables

 The ratio of independent random variables arises in many applied problems. In this article, the distribution of the ratio X/Y is studied, when X and Y are independent Rice random variables. Ratios of such random variable have extensive applications in the analysis of noises of communication systems. The exact forms of probability density function (PDF), cumulative distribution function (CDF) a...

Determinants of Technical Efficiency of the Dairy Farmers in Ada’a District of Oromia State, Ethiopia

The study was conducted to indicate the determinants of technical efficiency of the dairy farmers in Ada’a district of Oromia state, Ethiopia. The study was arranged in four purposively selected peasant associations of the peri-urban and four kebeles of the urban dairy production sub-systems from which thirty dairy farmers were selected randomly. A total of two hundred forty respondents were pe...

ADOPTION OF MUNGBEAN TECHNOLOGIES AND TECHNICAL EFFICIENCY OF MUNGBEAN (Vigna radiata) FARMERS IN SELECTED AREAS OF BANGLADESH

Mungbean is one of the most important pulse crops in Bangladesh. The demand of mungbean is very high due to its good taste. To date, different national institutes released 14 improve mungbean varieties with complete package of technologies and disseminated them to the farmers. But, the farm level adoption of mungbean varieties, their economics, and farmer’s efficiencies are not well known to th...
