The aim of this paper is to isolate the long run movements on equilibrium interest rate (or natural rate of interest) and potential growth. This estimations has been compute for US and Germany using a methodology developed by Laubach and Williams that is based on a Kalman Filter estimation of this two unobserved variables in a reduce structural model.

Tomato plants (Lycopersicon esculentum Mill. cv. Marglobe) were grown in a glasshouse with two light intensities (Control; +Light) and two NO 3 − /NH 4 + ratios (100/0; 80/20). Nitrate-ammonium-fed plants grown with a high light régime displayed a decrease of N, P, K, Ca and Mg absorptions. A strong reduction of growth rates (30%–29%) and yields (57%–48%)(More)
