Kimberly Rollins; Diana E. Dumitras

This study provides information about people’s valuation of recreational user days on public lands. The contingent valuation method is used with a random paired dichotomous choice question format. A bivariate probit model is utilized to estimate parameters of a willingness to pay function, which is used to calculate welfare measures associated with trips to three different sites and eight diverse recreational activities.The results indicate that recreational values vary by site and by activity.

An ex-ante impact assessment of the Common Agricultural Policy reform in the North-Western Romania

Mugurel I. Jitea; Diana E. Dumitras; Alexandru Simu Vasile

This paperwork represents a debate upon the methods of processing experimental data. One suggests, this way, the fact that the repetitions are introduced into the experiment in order to eliminate accidental situations and to determine the average effect. Starting from this truth one proposes to operate in the data processing with average values on repetitions. This way, the variation between variants becomes total variation, and the interaction component is implicitly assigned on the factors studied on the experiment. The method has the advantage that the processing of the information becomes much simpler, the test becoming much severe.
