Fuel Economy Regulations

In the 1980s and 1990s, a central debate in academic political theory was between liberals and communitarians, Kantians and Hegelians, Rawls and his critics. Bonnie Honig’s Political Theory and the Displacement of Politics (1993) disrupted this debate and argued that surface disagreements conceal an underlying consensus that the purpose of political theory is to answer, once and for all, the fundamental political questions. Drawing upon and transforming the work of Hannah Arendt and Friedrich Nietzsche, Honig argues that democracy requires attentiveness to the remainders of politics and a proclivity to contestation. To show the continuing relevance of Honig’s conception of agonistic democracy, I criticize Cass Sunstein’s account of the regulatory state for its displacement of politics, focusing on how his advocacy of fuel economy regulations occludes the political question of rethinking public transportation.

This paper will discuss the development and testing of an electric drive option designed for the propulsion system of the US Navy’s DDG 51 Class ships. It will briefly explain the history of the Hybrid Electric Drive (HED) program, including that of its predecessor, Proof of Concept (PoC), and the HED’s planned shipboard installation schedule. Operating at lower ship speeds, in a range where the currently installed propulsion gas turbines are less fuel efficient, the HED is expected to increase the ship’s fuel economy, allowing the ship to remain on station accomplishing its mission for a longer period of time. This paper will discuss how the gas turbine propulsion system, in concert with the HED, will be used to provide the most fuel efficient drive combination for various operating scenarios. Also covered will be a description of the major stakeholders involved in the HED’s development and implementation along with some of the constraints and challenges that were encountered in the testing phase of the program, both at the OEM facilities and at the US Navy’s Land Based Engineering Site (LBES) in Philadelphia PA. Planned fuel economy testing results obtained at the LBES facility will also be presented, intended to determine an estimate of the fuel savings that can be expected when the system is first placed in service on USS TRUXTUN (DDG 103) July 2018.

Household Heterogeneity

This paper employs an empirically estimated model to study the equilibrium effects of an increase in the US corporate average fuel economy (CAFE) standards. I identify and model heterogeneity across firms and find that the profit impacts of CAFE fall almost entirely on domestic producers. The welfare analyses consider the simultaneous household decision of vehicle and miles traveled, allowing direct comparison with a gasoline tax. Finally, I consider dynamic impacts in the used car market. I find these comprise nearly half the gross welfare cost of CAFE and fall disproportionately on low-income households. Contrary to previous results, the overall welfare costs are regressive. (JEL H24, L51, L62)
