Therefore, autoregressive distributed lag (ARDL) approach used. Hence, Long-run relationship is identified between macroeconomic variables and the agricultural revenue. Price variable of agricultural products has a positive effect in long-run and a negative effect in short-run. Interest rate has negative relationship in short-run and long-run with the agricultural revenue. Real exchange rate has a positive relationship in long-run with the agricultural revenue, while it is not significant in the short-run. Also results indicate that liquidity has positive relationship in long-run with the agricultural revenue. Increasing liquidity has a positive relationship in the current period and a negative relationship in the next period in short-run. Considering the results, effect of petroleum revenues in short-run and long-run is Low and negative. Imbalance of short-run adjusted to long-run after about two years.
