We first summarize the dominant interpretations of the "frontier" in the United States and predecessor colonies over the past 400 years: agricultural (1610s-1880s), industrial (1890s-1930s), scientific (1940s- 1980s), and algorithmic (1990s-present). We describe the difference between the...

The changing pattern of urban logistics with the growth in supply chain management and the increased adoption of e-commerce has implications for the location of warehousing and trucking facilities. Intuitively, as the supply chain becomes more sophisticated then more localized depots and...

Technical industrial clusters are defined and analyzed for a sample of U.S. metropolitan regions. Economic structure, spatial proximity and shape of the clusters are examined across the metropolitan regions through various economic and spatial measures and statistics. The data for this research...

Improvements in telecommunications and transportation appear to be bringing the world closer making physical location less of a factor in determining interaction between nations. The formation of regional and global trading pacts and arrangements seem to be further contribution to this...

small-world networks' have a high degree of local clustering or cliqueness, like a regular lattice and a relatively short average minimum path, like a completely random network. The huge appeal of 'small-world'networks' lies in the impact they are said to have on dynamical systems. In a...

In this paper we explore how satellite images of global night lights from the years 2001 to 2007 can be used to estimate economic activity at the sub-regional level in the U.S., India and China. The night lights based estimates of economic activity are then spatially analyzed and compared with...

Foreclosures are spatially contagious by nature (Can 1998). Abandoned or vacant properties have a negative spillover effect, by reducing the expected return on investment on surrounding properties. While there is a growing body of literature focusing on the latest wave of foreclosures in the US...

In this paper we develop an exploratory non-parametric clustering model of spatial and/or spatio-temporal phenomena based on Kolmogorov entropy. The methodology will be tested using quarterly HPI (Housing Price Index) data for 350 plus cities in the US from the Federal Financing and Housing...

Over a period of little more than five years, Blockchain, a cryptographic tamper-proof record keeping solution with decentralized control and distributed processing has become a go-to technology that appears to provide a permanence of verified provable record keeping in a fast- changing...

Money - a medium of exchange and store of value - has been evolving ever since its inception a few thousand years ago. Among many evolutionary changes, the one that occurred in the first decade of 21st century is likely to be a defining moment that will divide the history of money into two...
