This research explores the theoretical and applied issues associated with endogenous switching systems where market prices are bounded by policy instruments such as price supports Options for estimation of model parameters and their associated standard errors are identifdied and explored...

This paper estimates a multivariate tobit system of monthly wholesale dairy prices where 4 prices are lower censored by the dairy price support program. Using Maximum Simulated Likelihood (MSL) we test/correct for the effects of simulation noise and present two tests for estimating multivariate...

The occurrence of low night temperatures during reproductive development is one of the factors most limiting rice yields in southern Australia. Yield losses due to cold temperature are the result of incomplete pollen formation and subsequent floret sterility. Researchers have found that in 75%...

Nitrogen is a crucial input for the efficient production of rice and is generally applied in two split treatments, before flooding the rice paddocks at sowing time and within a week after the beginning of the panicle initiation stage. There is no pre-sowing test to estimate nitrogen requirements...

The QPLU$ Merino breeding project began in the early 1990s. The aim of the project was to demonstrate the efficiency of using a selection index to achieve breeding objectives. A number of selection lines were created from three strains of Merino sheep. During the ten-year course of the project,...
