Determining Optimal Levels of Nitrogen Fertilizer Using Random Parameter Models

Tumusiime, Emmanuel; Brorsen, B. Wade; Biermacher, Jon T.; … - Southern Agricultural Economics Association - SAEA - 2010

The parameters of yield response functions can vary by year. Past studies usually assume yield functions are nonstochastic or ‘limited’ stochastic. In this study, we estimate rye-ryegrass yield functions where all parameters are random. Optimal nitrogen rates are calculated for two yield...

Selecting random parameters in discrete choice experiment for environmental valuation: A simulation experiment

Mariel Chladkova, Petr; Abdullah, Sabah; De Ayala … - Departamento de Economía Aplicada III (Econometría y … - 2010

This paper examines the various tests commonly used to select random parameters in choice modelling. The most common … procedures for selecting random parameters are: the Lagrange Multiplier test as proposed by McFadden and Train (2000), the t …-statistic of the deviation of the random parameter and the log-likelihood ratio test. The identification of random parameters in …

Commodity Price Pass-Through in Differentiated Retail Food Markets

Richards, Timothy J.; Allender, William J.; Pofahl, … - Agricultural and Applied Economics Association - AAEA - 2010

Prices for nearly all basic commodity rose at unprecedented rates throughout early 2008, only to fall nearly as fast as financial markets and global economies began to collapse. Rising food prices in 2008 led to concerns that commodity price spikes would lead to more general food inflation, but...

Should all choices count? Using the cut-offs approach to edit responses in a choice experiment

Bush, Glenn; Colombo, Sergio; Hanley, Nick - 2009

Should we give equal weight to all responses in a choice experiment? Previous Choice Modelling papers have considered the issue of the internal consistency of choices – such as the extent to which strictly-dominated options are chosen. In this paper, a different focus is employed, namely the...

Modal image: candidate drivers of preference differences for BRT and LRT

Hensher, David; Mulley, Corinne - In: Transportation 42 (2015) 1, pp. 7-23

The physical image of transport systems, as perceived by users and non users, has long been put forward as a powerful influence on the formation of preferences. One setting for this is in the choice between bus rapid transit (BRT) and light rail transit (LRT) where there appears to be a strong...
