This paper develops a spatial theoretical growth model in order to study the impact of physical and human capital relocations on the growth of open economies. Analytical and simulation results show how the respective neighbours determine an economy's development, why convergence and divergence may alternate in the medium-run, and that interregional migration as a consequence of wage inequalities causes disparities to prevail in the long-run. The empirical part applies spatial econometric specifications for European regions on the NUTS2 level for the observation period 2000-2010. The estimations underline the importance of human capital endowments and its relation with spatial location. (author's abstract) / Series: Working Papers in Regional Science

An extended neoclassical rotation theory (poloidal and toroidal) is developed from the fluid moment equations, using the Braginskii decomposition of the viscosity tensor extended to generalized curvilinear geometry and a neoclassical calculation of the parallel viscosity coefficient interpolated over collision regimes. Important poloidal dependences of density and velocity are calculated using the Miller equilibrium flux surface geometry representation, which takes into account elongation, triangularity, flux surface compression/expansion and the Shafranov shift. The resulting set of eight (for a two-ion-species plasma model) coupled nonlinear equations for the flux surface averaged poloidal and toroidal rotation velocities and for the up-down and in-out density asymmetries for both ion species are solved numerically. The numerical solution methodology, a combination of nonlinear Successive Over-Relaxation(SOR) and Simulated Annealing(SA), is also discussed. Comparison of prediction with measured carbon poloidal and toroidal rotation velocities in a co-injected and a counter-injected H-mode discharges in DIII-D [J. Luxon, Nucl. Fusion 42, 614 (2002)] indicates agreement to within <10% except in the very edge in the co-injected discharge.

This thesis consists of three essays on macroeconomic aspects of climate change. Technological Trends and the Intertemporal Incentives For Fossil-Fuel Use analyzes how (the expectations about) the future developments of different kinds of technology affect the intertemporal incentives for fossil-fuel use. I find that improvements in the future state of technologies for alternative-energy generation, energy efficiency and total factor productivity all increase fossil-fuel use before the change takes place. The effect of changes in the efficiency of non-energy inputs is the reverse, while the effect of changes in fossil-fuel based energy technology is ambiguous. These conclusions are robust to a number of variations of the assumptions made. The Role of the Nature of Damages considers to what extent the choice of modeling climate impacts as affecting productivity, utility or the depreciation of capital affects the behavior of integrated assessment models. I carry out my analysis in two different ways. Firstly, under some simplifying assumptions, I derive a simple formula for the optimal tax on fossil-fuel use that adds up the three different types of climate effects. Secondly, I use a two-period model with exogenous climate to analyze how the allocation of fossil-fuel use over time is affected by the effects of climate change. I find that this is sensitive to the assumptions made. Indirect Effects of Climate Change investigates how direct effects of climate change in some countries have indirect effects on other countries going through changing world market prices of goods and financial instruments. When calculating the total effects of climate change, these indirect effects must also be taken into account. I first derive these indirect effects in a many-country model. Reaching agreements about reductions in the emissions of greenhouse gases is made difficult by the negative correlation there seems to be between emissions of greenhouse gases and the vulnerability to climate change. I argue, based on a stylized two country example, that trade in goods will tend to make the countries' interests more aligned while trade in financial instruments will tend to make the countries' interests less aligned.

The first essay of this dissertation analyzes the claim that a Marshallian total surplus optimum characterizes a second-best Pareto optimum in a general equilibrium model with price makers. The main result of this essay is that a Marshallian total surplus optimum corresponds to a second-best Pareto optimum when (i) the consumer's preferences are quasi-linear with respect to a numeraire, and (ii) for all other markets except the one under consideration, first-best (or Paretian) optimality conditions are satisfied. The second essay characterizes the optimal regulatory policy for point-source pollution emissions when firms are competing in Cournot fashion in the product market and have private information about their own cost. It is shown that the optimal regulatory policy benefits from the strategic interaction between the firms in the output market even though the firms' private information is uncorrelated. The firms strategic interaction in the output market acts as an information correlation externality that mitigates the wellknown "rent-extraction efficiency" trade-off. Each firms' opportunity to over-report their costs is reduced because the output market's strategic interaction reduces the profitability of infra-marginal units if they do. The main result shows that optimal environmental regulations discriminate between firms of given industry. Moreover, it is shown that if the regulator believes that firm A is always more likely to be efficient than firm B (in the sense of first-order stochastic dominance) and that both firms are equally efficient ex post, then firm A faces a higher marginal tax than its competitor. In light of this result, it is argued that the model provides theoretical foundations for grandfather clauses in environmental regulations.

This thesis consists of revised versions of five published papers on the development of neoclassical distribution theory, in the English-speaking world together with an introduction and conclusion, which draw together the themes of the papers. The thesis covers the origins of neo-classical distribution theory in the English-speaking world in the work of Jevons and Marshall, through to the second generation of Wicksteed, Clark and Pigou, and finally on to the 1930s and the new perspectives of Hicks and Robinson. Drawing on archival sources and primary and secondary texts, these essays review the major statements on distribution theory made by key figures in the Jevonian and Marshallian marginalist traditions. The essays shed new light on the origins of neoclassical distribution theory and provide insights into the methodology of nascent neoclassical distribution theory. A drive towards a universal, all-embracing marginal productivity theory of the distribution of income characterises the work of Clark and Wicksteed, but not so Marshall. A formalist mode of analysis, which was to become the hallmark of neoclassical economics in the second half of the twentieth century, is also evident in key works of the period. However, the role of empirical evidence in theory generation and appraisal remains an undeveloped component of late nineteenth and early twentieth century neoclassical theory—Marshall again provides an exception to the general rule. There is a common adherence, among the key figures examined, to the joint proposition that competitive market wage outcomes are ‘fair’, but that low incomes (fair or not) are unjust when they fail to meet minimum needs standards. State remedial action (tax and expenditure policies) is required to remove such injustices. Robinson’s theory of exploitation provided an important extension to the neoclassical normative framework. She highlighted the extent to which labour may be exploited due to imperfections in both product and labour markets.

This dissertation applies a Neoclassical Realism model to examine how the evolution of United States (U.S.) national security strategy-making institutions has resulted in a path dependent accrual of autonomy and increasing influence over the formulation of American grand strategy. Once U.S. national security strategy-making institutions were created, their existence inexorably led to increasing autonomy, the creation of new strategy-making institutions, and subtle influence in shaping American grand strategy by preferential focus on a militarized foreign policy. Additionally, the more autonomous these strategy-making institutions have become, the further they have strayed from the Constitutional mandate to create a government which provides for the common defense and the less successful they have been in implementing grand strategy for national security. This dissertation examines this evolution in strategy-making institutions across three grand strategic moments: the end of the Spanish-American War (1898-1911), World War II and the beginnings of the Cold War (1940-1950), and the end of the Cold War (1980-present). Each case study discusses the historical facts of the grand strategic moment’s evolution in strategy-making institutions. These facts indicate durable shifts in autonomy and influence. The increasing autonomy is evidenced by the ability of these national security strategy-making institutions to define their own evolution, despite traditional American strategic culture perceptions about civilian control of the Military. These strategy-making institutions also shaped the formulation of American grand strategy and their evolution has had important transformative effects on American strategic culture and civil-military relations. While, fortunately, the U.S. can rely on ethical military professionalism, and the nation still holds its Military in high regard, this path-dependent process of structural evolution generates concern for the American People’s future and common defense.
