Table 7. Significant factor effects (P < 0.05) and 95% confidence intervals based on stepwise OLS regression of simulation design for simulation periods t = 3, t = 5, and t = 13. The response variable is the average economic land rent. IBC stands for interest on borrowed capital, IEC stands for interest on equity capital, MA stands for cost savings due to managerial ability, POL stands for the policy scenario, and TC stands for technological change.
