This paper develops a model of economic growth and activity locating endogenously on a 3dimensional featureless global geography. The same economic forces influence simultaneously growth, convergence, and spatial agglomeration and clustering. Economic activity is not concentrated on discrete isolated points but instead a dynamically-fluctuating, smooth spatial distribution. Spatial inequality i...

This thesis examines several distinct aspects of agglomeration externalities within an urban economy. In particular, the work focuses on location decisions of agents who face trade-offs between advantages in dense locations versus cheaper land prices available in suburban and exurban regions of the city. Two general equilibrium models of location are presented which study different aspects of l...

With the retirement of coal-fired power stations, wet-stored stockpile fly ash is increasingly receiving attention for use in concrete. An important consideration dry this application its impact on air entrainment, which can be affected by unburnt carbon present, influencing bubble stability and air-entraining admixture (AEA) dose requirements. Preliminary tests suggest wet storage influence pr...

Particle aggregation and film agglomeration have been among the main technical hurdles for solid-state thin film development and have been observed in many semiconductor and catalytic systems. In heterogeneous catalysis, particle aggregation leads to reduction of effective surface area and degradation of catalytic performance. On semiconductor surfaces, film agglomeration may give rise to elect...

Agglomeration of nanoparticles in biological fluids is a pervasive phenomenon that leads to difficulty in the interpretation of results from in vitro exposure, primarily due to differing particokinetics of agglomerates to nanoparticles. Therefore, well-defined small agglomerates were designed that possessed different particokinetic profiles, and their cellular uptake was compared to a computati...

This paper implements a fair wage constraint in the fashion of Akerlof and Yellen (1990) into an analytically tractable core-periphery agglomeration model. This enables us to study the role of imperfect labour markets for the pattern of agglomeration. We illustrate that, in the short run, a marginal increase in fair wage preferences leads to an unambiguous compression of the national factor pri...

Tourism generates increased income and employment in host countries and regions which substantially improves local economies. On the other hand, the manufacturing sector remains the most important part in regional and national economies. By explicitly embedding a nontraded good sector into a new economic geography model, we were able to investigate the interdependence between the tourism sector...
