Positive Controllability Of Systems With Nearly-Non-Negative Matrices, Theodore Sonne Perry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper analyzes the controllability of constant coefficient linear differential equations and presents two proofs of a major theorem on controllability. Properties of nearly-non-negative matrices are discussed and in particular a theorem on the behavior of the exponential matrix of nearly-non-negative matrices is proven. These results are then used to prove that the reachable set for systems with nearly-non-negative matrices is limited to the positive hyperoctant.

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 …
