A Rationale For Furrow Irrigation System Design And Management, Safa Noori Hamad

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mathematical and computerized models are developed to design and optimize furrow irrigation systems. The optimization process starts with land grading design, if any is needed, followed by a prediction of maximum non-erosive furrow stream size allowed on a given soil and the associated furrow-advance function. An average depth of application per irrigation is then assumed from which the wetting pattern along the furrow and the amounts of runoff water are predicted. A design of an Irrigation Runoff Recovery System, IRRS, is then executed, if desired, and system cost is determined. Using the predicted wetting pattern and the appropriate Crop Production …

The Impact Of Monopoly Power On A Commercial Banking Firm, John Atwood Tribble

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The commercial banking industry is often criticized on the grounds that there is a high concentration of market power in the hands of a few firms. However, the appropriate measure of market power is Lerner's index of monopoly power, the elasticity of demand, not concentration ratios. The theoretical model developed in the paper is designed to permit the estimation of demand and supply elasticities in the banking industry. Specifically, two assets (loans and state and local funds) and one liability (time deposits) are investigated.

The empirical model focuses its attention on the demand and supply conditions. If the bank is …
