Table 8 Aggregate effect of water and feed scarcity on output, food expenditure, and food security
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 |
