In The Syntax of Nonfinite Complementation: An Economy Approach, the author completes two major research projects that solidify the foundation of the Minimalist Program: the elimination of c-selection and government. He then investigates in detail the nature of the Economy Principles in syntax. The discussion, which focuses on infinitival and participial complements, shows that a number of facts that previously have either not been accounted for or have received unsatisfactory treatment can be explained in a principled way once Economy Principles and, more generally, the Minimalist Program are adopted.
