This research focuses on two key research questions: how to measure spatial accessibility to green space in urban areas at fine resolution; and what is the status of spatial inequity in accessibility to green space in the MMA. Guided by the two research questions and based on a systematic review of literature on accessibility in general accessibility to green space in particular, a methodology has been developed for producing results needed to answer the research questions.

How much does household collateral constrain regional risk sharing? construct a new data set of consumption and income data for the largest U.S. metropolitan areas, and we show that the extent of risk-sharing between regions varies substantially over time. In times when US housing collateral is scarce nationally, regional consumption is about twice as sensitive to income shocks.

On Fiscal Discipline and the Choice of Exchange Rate Regine This result conflicts with a well-known recent result from Hoxby (2000a), who argues that metropolitan areas with less centralized educational governance, and therefore more competition among local school districts, produce better student outcomes at lower cost. In Chapter Two, I attempt to get to the bottom of the discrepancy. I reanalyze a portion of Hoxby’s data, and find reason to suspect the validity of her conclusions.

THE ROLE OF IMPORT SUBSITITUTION AND EXPORT ORIENTATION STRATEGIES ON THAILAND'ECONOMIC GROWTH This result calls the incentive effects of Tiebout choice into question, as it indicates that administrators of effective schools are no more likely to be rewarded with high demand for local housing in high-choice than in low-choice markets. To explore this further, I estimate models for the effect of Tiebout choice on mean scores across metropolitan areas. Consistent with the earlier results, I find no evidence that high-choice markets produce higher average SAT scores.

Migration and Economic Development: The Case of the Mouride Brotherhood From Senegal to the Washington D.C. Metropolitan Area, 1990-2000 Effectiveness sorting should be observable as a magnification of the causal peer effect, as it creates a positive correlation between the peer group and an omitted variable— school effectiveness—in regression models for student outcomes.

MANAGING SUPPLY CONTRACTS AND INVENTORY RISKS IN A SUPPLY CHAIN This seems a more accurate characterization of Tiebout markets, as the median U.S. metropolitan area has fewer than a dozen school districts from which to choose. It leads to a substantially different understanding of the market dynamics, as Hoxy’s assumption of competing schools with identical peer groups eliminates the “stickiness” that concern for peer group can create and that is the primary focus here.

Monetary Policy , the Banking System, and Short -term Money Instrusments Measuring market concentration I define local housing markets as Metropolitan Statistical Areas (MSAs), Census Bureau approximations of local housing markets defined by observed commuting patterns.35 The SAT data that I use to measure student outcomes are taken from the early 1990s. Consequently, I use 1990 MSA definitions and draw demographic characteristics of each MSA from the 1990 Census.

COMPETITIVE RESPONSE TO RADICAL PRODUCT INNOVATIONS The competitive case serves as a baseline, but it is not a realistic description of choice in the presence of peer group externalities. I next consider a market with ten equally-sized districts, a degree of Tiebout choice that, as is discussed below in Section 1.4, corresponds roughly to the 80th percentile U.S. metropolitan area.

Campus and Metropolitan Area Networks (MANs) Metropolitan area networks (MANs) are network technologies similar in nature to local area networks (LANs), but with the capability to extend the reach of the LAN across whole cities or metropolitan areas, rather than being limited to, say, 100-200 metres of cabling. MANS have evolved because of the desire companies to extend LANs throughout company office buildings of spread across a campus or a number of different locations in a particular city.
