Hoeksema has been instrumental in the study of negative polarity, and his work is part of the Dutch school of generalized quantifier theory. He is especially known for applying results from the study of monotonicity to polarity phenomena, and in criticizing too narrow construals of what counts as a polarity licensor. He has also worked extensively on the historical development of various aspects of grammar, mostly from corpora of Dutch and English, including documenting the changes in polarity items and in quantifiers.
