This paper introduces an extension of the balanced augmented empirical likelihood method for estimating simulation models. We analyze its performance empirically using MonteCarlo methods, and demonstrate that our new method increases the flexibility and accuracy of the empirical likelihood approach, while preserving both its limit distribution and its consistency for moment condition models. We...

crop models need more evaluation and study for use in deficit irrigation. the main objective of this paper was to study the efficiency and accuracy of dssat model, in estimating of moisture in the soil profile under two levels of water application¬¬¬ in silage maize field. two irrigation treatments including deficit irrigation (0.7 smd), and a full irrigation (smd) were considered for two years...

The ultimate goal of monetary policy is to achieve price stability and favorable economic growth through policy tools. The purpose of this paper is to determine the optimal monetary policy rule and measure and evaluate the effectiveness of monetary policy in an elected economy -Pakistan- with optimal control method. In this way, using Dyn‌amic Programming, monetary policy maker's loss function ...

The main objective of the present study is to analyze the effects of agricultural crop insurance on farmers’ technical efficiency and risk attitude. Required data came from questionnaires that were completed by the Institute for Planning and Agricultural Economics of the Ministry of Agriculture. Farmers’ technical efficiency and attitude toward risk were estimated using stochastic frontier prod...

Several measures of life cycle cow efficiency were calculated using weights and individual feed consumptions recorded on 160 dams of beef, dairy and beef X dairy breeding and their progeny. Ratios of output to input were used to estimate efficiency, where outputs included weaning weights of progeny plus salvage value of the dam and inputs included creep feed consumed by progeny plus feed consum...

We investigate that no-knowledge measurement-based feedback control is utilized to obtain the estimation precision of the detection efficiency. For the feedback operators that concern us, noknowledge measurement is the optimal way to estimate the detection efficiency. We show that the higher precision can be achieved for the lower or larger detection efficiency. It is found that no-knowledge fe...
