Applications for risk diversification strategies in addressing conservation problems commonly ignore upper limits in returns, which may not reflect the fact that these economic returns are often beyond the scope of what conservation assets can produce given constraints on species, sites, or activities. This research identifies the consequences of failing to account for upper limits on returns from conservation in a modern portfolio theory (MPT) framework. We find that the amount of risk reduction conservation organizations can achieve with the same level of compromise in the expected return on investment is higher when returns are constrained.

This study estimates the influence of proximity to water bodies and park amenities on residential housing values in Knox County, Tennessee, using the hedonic price approach. Values for proximity to water bodies and parks are first estimated globally with a standard ordinary least squares (OLS) model. A locally weighted regression model is then employed to investigate spatial nonstationarity and generate local estimates for individual sources of each amenity. The local model reveals some important local differences in the effects of proximity to water bodies and parks on housing price.
