Rim: Conservation restrictions and farm prices in Minnesota

In alr4: Data to Accompany Applied Linear Regression 4th Edition

Description

These data include nearly every farm sale in 6 economic regions in Minnesota from 2002-2011 that either has land enrolled in the federal Conservation Reserve Program, or CRP, or has no restrictions. A few sales with non-crp land easements were excluded. CRP enrollment is for a fixed period during which farmers agree not to grow crops for a fixed payment. This can effect sale price of land since buyers have fewer choices on use of land that could lower values, but also have guaranteed income for a fixed period that could raise values.

Usage

data(MinnLand)

Format

A data frame with 18700 observations on the following 10 variables.

acrePrice

sale price in dollars per acre. Sale prices were adjusted to a common date within the year. No inflation adjustment is made between years.

region

a factor with levels giving the geographic names of six economic regions of Minnesota. Excluded economic regions had few farm sales.

improvements

percentage of property value due to improvements. Minnesota assessors estimate values separately for land and buildings. This variable is the ratio of the building value to the total value.

year

year of sale, as a continuous variable, not as a factor. Most uses of this variable would require converting it to a factor.

acres

size of the farm in acres

tillable

percentage of farm acreaage that is rated arable by the assessor

financing

a factor with levels title transfer and seller finance

crpPct

the percentage of all farm acres enrolled in CRP

productivity

average agronomic productivity scaled 1 to 100, with larger numbers for more productive land. This score is based on University of Minnesota soil studies. This value is frequently missing because some counties never had the study done, and some county assessors are inconsistent in including this value in the record of the sale.

Details

Data is collected from Minnesota counties. Some counties do not include the productivity value in sales records, accounting for most of the missing values. The variable tillable is also frequently missing.
