Professor Hays is interested in the interconnections between domestic politics and the international economy. He has studied the effects of politics on the financial markets of both the developed democracies and emerging market democracies. His book, Globalization and the New Politics of Embedded Liberalism, examines the roles that socio-economic and political institutions play in shaping how OECD governments respond to globalization (OUP, 2009). His methodological interests relate to modeling spatio-temporal dependence in time-series-cross-sectional and panel data.
