Social psychology and environmental economics: a new look at ex ante corrections of biased preference evaluation∗

The field of social psychology explores how a person behaves within the context of other people. The social context can play a substantive role in non-market allocation decisions given peoples choices and values extend beyond the classic market-based exchange institution. Herein we explore how social psychology has affected one aspect of environmental economics: preference elicitation through s...

Decision Tree Pruning: Biased or

We evaluate the performance of weakestlink pruning of decision trees using crossvalidation. This technique maps tree pruning into a problem of tree selection: Find the best (i.e. the right-sized) tree, from a set of trees ranging in size from the unpruned tree to a null tree. For samples with at least 200 cases, extensive empirical evidence supports the following conclusions relative to tree se...

The Truth About Consequences and Corrections

Restriction of range occurs whenever design or circumstances abbreviate the values of one or both variables being correlated. Range restriction has an impact on score validity, score reliability, and statistical power. As a result, researchers need a more sophisticated concept of the relationship between.variance and correlation than the simple assumption that when variance goes down, correlati...
