A recent paper by Harvard economists Daniel Shoag and Peter Ganong titled, Why Has Regional Convergence in the U.S. Stopped? indicates that land development regulations tend to increase housing costs, which contributes to inequality by excluding lower-income households from more economically productive urban regions. Does this means that planners are guilty of increasing income inequality?
Congratulations to this year's high school, college and university graduates! The current crop includes our son, who was recruited by a major corporation. The location of his new job will affect his travel patterns and therefore the transportation costs he bears and imposes for the next few years: until now he could get around fine by walking, cycling and public transport, but his new worksite is outside the city center, difficult to access except by automobile. As a result he will spend a significant portion of his new income to purchase and operate a car, and contribute to traffic congestion, parking costs and pollution. This is an example of how land use decisions, such as where corporations locate their offices, affects regional transport patterns and costs.
People love statistics. They let us understanding the world beyond our own senses. USA Today publishes a daily Snapshot which presents a graph of random statistics. Sports talk and business analysis are dominated by statistics. We measure our progress, or lack thereof, and compare ourselves with others, based on statistics about our size, activities and accomplishments.
