Neal’s research focused on the design of water markets, particularly market mechanisms for managing major water storages. Recently, Neal’s PhD research was used to inform the ACCC Murray Darling Basin water market inquiry. Neal’s PhD also explored the application of machine learning techniques to economics.

Since returning to the APS, Neal has led several major projects at ABARES, including the development of new economic models of Australian farms and water markets, drawing on techniques developed as part of his thesis. At ABARES, Neal has produced a range of research on agricultural policy issues including the effects of drought and climate change on Australian farms, and water policy in the Murray-Darling Basin. Neal writes regularly on these issues in The Conversation.
