Three concepts of ‘hit’
• ‘First Hit’: first month after January 2007 with a negative residual exceeding two standard deviations; if none, ‘not yet’
• ‘Most Severe Hit’: The largest shortfall of exports relative to the smoothed trend
• ‘Largest Hit’: The largest month-on-month fall of exports

VS – an Input Output Measure
• 9 Asian countries and USA, 2000• Flows by industry and country
ΔX = (I-A)-1 ΔY
(I-A)-1 = I + A + A2 + A3 +
ΔX1 = ΔY
ΔX2 = ΔY + AΔY = (I + A) ΔY
ΔX3 = ΔY + AΔY + AAΔY = (I + A + A2) ΔY
