| Agricultural economists have recently been attracted to procedures suggested by Granger and others which allow observed data to reveal causal relationships. Results of this study indicate that "causality" tests can be ambiguous in identifying behavioral relationships between agricultural price variables. Caution is suggested when using such procedures for model choice. |

| In this study a complete survey of all WJAE articles was conducted. The 158 titles that have appeared in the WJAE as of December 1981 are categorized by institutional category, authorship affiliation, and subject category. These results are compared to similar studies concerning the SJAE and AJAE. Our findings indicate that the WJAE has a broad range of contributors and is not dominated by any one institution, author, or group of authors. We feel that these and other interesting results are of general interest to all WJAE readers. |

| Agricultural economists at land-grant universities were surveyed to evaluate the use and assessment of professional journals. Faculty rankings of journals are reported along with faculty perceptions of changes in the quality of selected journals. Of 25 journals used by agricultural economics faculties, the Southern Journal of Agricultural Economics ranked first among regional agricultural economics journals in personal usefulness, subscriptions held, papers submitted, papers published, and participation in the editorial and review processes. The SJAE was also ranked as the second most improved journal among all journals evaluated. |

| 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. |
