Many studies have reported a relationship between urban air pollution levels and respiratory health problems. However, there are notable variations in results, depending on modeling approach, covariate selection, period of analysis, etc. To help clarify these factors we compare and apply two...

There are three main global temperature histories: the combined CRU-Hadley record (HADCRU), the NASA-GISS (GISTEMP) record, and the NOAA record. All three global averages depend on the same underlying land data archive, the Global Historical Climatology Network (GHCN). Because of this reliance...

The persistence of high savings-investment correlations and home-country bias in portfolio construction at the national level is contrasted with new evidence of savings behaviour in Canadian provinces. We confirm that national borders clearly divert flows of capital to domestic investments, but...

Major insurance and reinsurance firms have expressed concern that global warming poses economic threats to the industry due to increased risk of extreme weather events. Past studies have examined the connection between global warming trends and the value of insured damages. In principle, if...

Empirical evidence has suggested a “resource curse” exists, in which countries with abundant resources may have higher initial consumption but then grow more slowly. The effect appears to be dependent on a country's political structure. Theoretical models not typically accounted for...

The Ontario Green Energy and Green Economy Act (herein the GEA) was passed in May 2009 with the purpose of addressing environmental concerns and promoting economic growth in Ontario. Its centerpiece is a schedule of subsidized electricity purchase contracts called Feed-in-Tariffs (FITs) that...

The persistence of high savings-investment correlations and home-country bias in portfolio construction at the national level is contrasted with new evidence of savings behaviour in Canadian provinces. We confirm that national borders clearly divert flows of capital to domestic investments, but...

The debate over whether urbanization and related socioeconomic developments affect large-scale surface climate trends is stalemated with incommensurable arguments. Each side can appeal to supporting evidence based on statistical models that do not overlap, yielding inferences that merely...

Annual global CO2 emission forecasts at 2100 span 10 to 40 billion tonnes. Modeling work over the past decade has not narrowed this range nor provided much guidance about probabilities. We examine the time-series properties of historical per capita CO2 emissions and conclude that per capita...
