Electronic structure calculations using the local density functional method with non-local norm-conserving pseudopotentials, ab initio molecular dynamics simulations, and a novel method of all-quantum simulations, combining a quantum path-integral description of the nuclear degrees of freedom with concurrent electronic structure calculations of the Born-Oppenheimer potential energy surface, wer...

The transition state region of the reaction OH + H2 -. H2O + H is investigated by photoelectron spectroscopy of the H3Oand D30anions. The peaks observed in the spectra are from a combination of vibrational progressions and overlapping anion -. neutral electronic transitions. The photoelectron angular distributions indicate that two processes contribute to the spectra; these are assigned to phot...

We introduce a skewness-based approach to measure tax progression and demand for redistribution. We provide a political economy foundation for a novel measure of skewness by expressing key properties of the classical model of voting over income redistribution (Meltzer and Richard, 1981) and the Prospect Of Upward Mobility (POUM) mechanism (Bènabou and Ok, 2001), as well as the conventional noti...

This paper develops a continuous time modeling approach for making optimal asset allocation decisions. Macroeconomic and "nancial factors are explicitly modeled as Gaussian stochastic processes which directly a!ect the mean returns of the assets. We employ methods of risk sensitive control theory, thereby using an in"nite horizon objective that is natural and features the long run expected grow...

We develop a model of entrepreneurial choice in which some individuals have a comparative advantage in starting new businesses. Ef…ciency dictates that entrepreneurs should specialize in start-ups and sell successful start-ups to professional managers. We consider the role of capital gains taxation. Capital gains taxes create an incentive for entrepreneurs to manage their own enterprises and av...

This paper presents a political economy model of inflation as a result of social conflict. Agents are heterogeneous in terms of income. Agents’ income levels determine their ability to hedge against the effects of inflation. The interaction of heterogeneous cash holdings and preferences over fiscal policy leads to conflict over how to finance government expenditure. The model makes a number of ...

We develop a dynamic general-equilibrium model of rational addiction to study the decisions concerning nonaddictive and addictive goods consumption, savings, labor supply, and production. The model consists of two-period lived overlapping generations and two separate theaters of economic activity: a composite good and an addictive good sector. We determine the relative price of the addictive go...

UK Households’ Carbon Footprint: A Comparison of the Association between Household Characteristics and Emissions from Home Energy, Transport and Other Goods and Services Does the association between household characteristics and household CO2 emissions differ for different areas such as home energy, transport, indirect and total emissions in the UK? Specific types of households might be more li...
