Regional Migration and House Price Appreciation
Despite both empirical and anecdotal evidence suggesting the importance of common systematic factors determining price appreciation in residential real estate markets, the existing literature focuses almost exclusively on the impact of local variables. This paper presents a theoretical model of an urban housing market allowing for explicit consideration of the role of interregional migration in response to changes in economic opportunities within a system of cities. The model identifies the importance of aggregate income and aggregate population growth in house price appreciation and suggests that housing demand and population growth within regions are jointly determined. Empirical tests of these predictions provide strong support for the model. In particular, changes in per-capita aggregate income are negatively related to both returns to housing and local population growth and omitting this systematic component from empirical specifications leads to an underestimation of the impact of local income. Furthermore, there is significant evidence of endogeneity problems in empirical specifications of the model that are similar to those found in the existing literature.Housing; interregional migration; metropolitan growth
Postmortem Examination of Turkeys
Examine the outside of birds for parasites, scratches, animal bites, and other signs of injury
Avian Pox (Fowl Pox)
This fact sheet addresses specifically fowl pox affecting backyard chickens
Principles of Feeding Small Flocks of Chickens at Home
Owning a small flock of chickens is increasing in popularity, particularly in areas prohibiting the raising of larger domestic animals. Chickens not only furnish a ready source of home-grown meat and eggs, but also provide great pleasure as exhibition stock and even as pets
Nutrient Content of Camelina Sativa and Feeding Trials in Turkeys
There is increasing interest in converting waste cooking oil and oil produced from oilseed crops, such as camelina, into biofuels in order to decrease dependence on petroleum products for fuel sources
Benthic Macrofauna of the New York Bight, 1979-89
The benthic macrofauna of the New York Bight has been monitored extensively, primarily to determine trends over space and time in biological effects of waste inputs. In
the present study, from 44 to 48 stations were sampled each summer from 1980-1985. Data from other Bight benthic studies are included to· extend the temporal coverage
from 1979 to 1989. Numbers of species and amphipods per sample, taken as relatively sensitive indicators of environmental stress, showed consistent spatial patterns. Lowest values were found in the Christiaensen Basin and other inshore areas, and numbers increased toward the outermost shelf and Hudson Shelf Valley stations. There were
statistically significant decreases in species and amphipods at most stations from 1980 to 1985. (Preliminary data from a more recent study suggest numbers of species increased again between 1986 and 1989.) Cluster analysis of 1980-85 data indicated several distinct assemblages-sewage sludge dumpsite, sludge accumulation area, inner Shelf Valley, outer Shelf Valley, outer shelf-with little change over time. The "enriched" and "highly altered" assemblages in the Basin appear similar to those reported since sampling began there in 1968. No consistently defaunated areas have been found in any sampling programs over the past 20 years. On a gross level, therefore, recent faunal responses to any environmental changes are not evident, but the more sensitive measures used, i.e. numbers of species and amphipods, do indicate widespread recent effects. Causes of the faunal changes are not obvious; some possibilities, including increasing effects of sewage
sludge or other waste inputs, natural factors, and sampling artifacts, are discussed. (PDF file contains 54 pages.
