In this article the performance of a grid-connected PV system supplying a farmstead was evaluated using a commercially available energy balance simulation model, Hybrid2. By performing annual hourly simulations, the influence of system size, actual radiation data, and estimated radiation data on economic and energy production were assessed. The estimated radiation data were developed from krigi...

This paper uses a structurally estimated macroeconometric model, denoted the MC model, to evaluate inflation targeting in the United States. Various interest rate rules are tried with differing weights on inflation and output, and various optimal control problems are solved using differing weights on inflation and output targets. Price-level targeting is also considered. The results show that 1...

During the 8th Five-Year Plan Period (1991-1995), China achieved an average annual economic growth rate of 12 percent, with a tremendous success. Yet at the same time it also experienced serious inflation, with the residents consumer price index rising at an annual average rate of 12.9 percent, and even reaching a peak of 24.1 percent in 1994. In view of this problem, in the Proposal on the 9th...

CONTEXT Tobacco use is a leading cause of preventable death in the U.S. and around the world. Increasing tobacco price through higher taxes is an effective intervention both to reduce tobacco use in the population and generate government revenues. The goal of this paper is to review evidence on the economic impact of tobacco price increases through taxation with a focus on the likely healthcare...

in recent years, sexed semen has been commercially available. due to its lower fertility and higher price compared to conventional semen, economic evaluation should be undertaken before recommending the technology to dairy producers in each country. the objectives of the present study were to evaluate the advantages and disadvantages of the sexed semen usage at farm level in economic conditions...

The robotization of on-site surface finishing work, particularly sandblasting, is considered. A possible system design is presented with a cost estimate. Costs and benefits of applying the proposed robot system to on-site sandblasting are outlined and estimated. Net present value of the contractor's investment in the robot equipment is analyzed. Conclusions regarding the purchase price of the r...
