Economic theories of systems of cities explain why production and consumption activities are concentrated in a number of urban areas of different sizes and industrial composition rather than uniformly distributed in space. These theories have been successively influenced by four paradigms: i)...

This chapter provides a survey of recent developments of positive as well as normative theories of city systems. Static theory of city system emphasizes the factors that result in the formation of cities through the interaction between two opposing forces: i) agglomeration economy; ii)...

What are the impacts of free trade agreement on the social welfare of different groups of labor force in a developed country? What is the impact of free trade on a developed country’s income disparity? What is the effect of free trade on the skill distribution of a developed country? The...

What are the impacts of free trade agreement on the welfare of different types of workers in a developed country? What is the impact of free trade on a developed country's income disparity? What is the effect of free trade on the skill distribution of a developed country? The objective of this...

In this paper I analyze the impact of basic training and specialized training on the distribution of skill, income disparity, social welfare, and on the structure of a decentralized specialized city system. This is done in a spatial general-equilibrium model of a closed economy producing a...

In this paper we develop a North-South trade model in which the South produces food and the North produces both food and a high-tech good. Food production is undertaken by unskilled workers, while the high-tech product is made only by horizontally differentiated skilled workers. Owing to the...

This paper proposes asymmetric GARCH-Jump models that synthesize autoregressive jump intensities and volatility feedback in the jump component. Our results indicate that these models provide a better fit for the dynamics of the equity returns in the US and emerging Asian markets, irrespective...

This study examines the relationship between inflation and inflation uncertainty for both developed and emerging countries using the asymmetric power GARCH model. We find new evidence that suggests that positive inflationary shocks have stronger impacts on inflation uncertainty for mainly Latin...
