Abstract
This study reviews articles using regression analysis published in the Journal of Agricultural and Resource Economics from 1994 to 1998 to determine agricultural economists' effectiveness in reporting and conveying research procedures and results. Based on the authors' experience of surveying articles for this study, several suggestions for reporting of results and how to better separate statistical from economic significance are offered. First, clearly define the dependent variable- preferably in the results table as well as within the text. Second, report parameter estimates in an interpretable form either in the results table or in a subsequent table. Third, report summary statistics. Fourth, report degrees of freedom conspicuously in the results table. Fifth, report if statistically insignificant variables have been dropped. Lastly, weigh economic importance aside from statistical significance and use simulation to express economic significance where appropriate.
