These effects, in turn, contribute to an increase in the debt-to-GDP ratio, raising concerns about the long-term sustainability of public debt. The objective of...

This note presents an algorithm for deriving first order conditions applicable to the most common optimisation problems encountered in dynamic stochastic models automatically. Given a symbolic library or a computer algebra system one can efficiently derive first order conditions which can then...

Energy storage is a potential alternative to conventional network reinforcement of the low voltage (LV) distribution network to ensure the grid’s infrastructure remains within its operating constraints. This paper presents a study on the control of such storage devices, owned by distribution...

Helicoverpa spp. (heliothis) are a major insect pest of cotton, grains and horticulture in the Murray‐ Darling Basin. Climate change is likely to make conditions more favourable for heliothis. This could cause regional comparative advantages in irrigation systems to change as management costs...
