This research examines the empirical properties of duality theory. A comparison of the Hessian matrices calculated from the normalized unrestricted and restricted profit, and production functions indicate that duality is highly sensitive to measurement error and relative price variability....

This research examines selected empirical properties of duality relationships. Monte Carlo experiments indicate that Hessian matrices estimated from the normalised unrestricted profit, restricted profit and production functions yield conflicting results in the presence of measurement error and...

This study investigates the dynamics of agribusiness stock returns and the market return for 22 firms in a switching-regression framework. Threshold levels and regression slopes are estimated and tested. Results indicate how parameters differ for alternative regimes, at what levels dynamic...

Recently, financial institutions have developed improved internal risk rating systems and emphasized the probability of default and loss given default. Also they have been affected by globalization and it became important to understand the way foreign banks operate. The probability of default is...

This study examines the change over time in agricultural congressional market power and production concentration using the Herfindahl-Hirschman Index and concentration ratios. Results indicate that the number of congressional districts representing the production of several crops has declined...

The present study uses local maximum likelihood (LML) methods recently proposed by Kumbhakar et al. (2007) to assess the technical efficiency of arable crop Kansas farms. LML techniques overcome the most relevant limitations associated to mainstream parametric stochastic frontier models. Results...
