From: Welfare and food security response of animal feed and water resource scarcity in Northern Ethiopia

Estimates Effect on output (Y) Effect on PCFE Total effect
Panel A using distance value \( \frac{dY}{dT} \) \( \frac{d\mathrm{PCFE}}{dT} \) \( \frac{d\mathrm{PCFE}}{dY}\frac{dY}{dT}+\frac{d\mathrm{PCFE}}{dT} \)
Water scarcity (Tw) − 0.155 − 0.133 − 0.142
Grazing scarcity (Tf) − 0.279 − 0.086 − .102
Straw scarcity (Tt) − 0. 328 − .0731 − .092
Panel B using shadow price
Water scarcity (Tw) − 0.074 − 0.0529 − .057
Grazing scarcity (Tf) − 0.094 − 0.0627 − .068
Straw scarcity (Tt) − 0.154 − 0.0421 − .051
