An objective method to associate local weather extremes with characteristic circulation structures

In this paper we give methods to find characteristic circulation patterns which are connected to local extreme temperature anomalies. Two data reduction techniques are applied: Legendre polynomial fitting and watershedding. For polynomial fitting a clear trend is found with respect to local temperatures. However, the trend is not distinctive enough to give clear answers on the type of circulation patterns belonging to local extremes. The main advantage of watershedding is that the physical properties of the circulation patterns are retained while the dimension of the data is largely reduced. Expert knowledge, however, is needed to model these main features as predictors

EQUILIBRIUM VERSUS DISEQUILIBRIUM IN THE MARKET FOR NON-FED CATTLE

Beef-cow inventory demand is considered in a disequilibrium model of the U.S. live non-fed cattle market. Statistical results indicated the possible presence of disequilibrium prices. However, post-model evaluation indicated that the market for non-fed cattle has not been characterized by significant disequilibrium price behavior.Demand and Price Analysis, Livestock Production/Industries,

POPULATION-SPECIFIC RECREATION DEMAND MODELS AND THE CONSEQUENCES OF POOLING SAMPLE DATA

This paper considers the implications of different geographical population definitions in analysis of demand for wildlife recreation. Demand functions for fishing, small game hunting, big game hunting, and wildlife enjoyment are estimated for individual Southeastern states and also for a pooled sample of all the states. Statistically significant differences between the state and regional estimates of the variable cost coefficient exist in 18 of the 40 cases. Consumer surplus values derived from state cost coefficients can differ greatly from values derived from pooled coefficients.Resource /Energy Economics and Policy,
