Her 2011 book The Linguistic Cycle: Language Change and the Language Faculty shows how cyclical change can be accounted for through an economy principle, while her Clause Structure (2013) examines a number of current debates in theoretical syntax. Her book The Diachrony of Meaning (2018) examines the history of argument structure.
