Collection of equations used for catastrophic costs calculation

Primary analysis: using the output approach including amount of vouchers and social welfare payments or cash transfers as income

$catastrophiccostsif\frac{\left(m,-,s\right)+n+i}{r+c+v}\ast 100>20\%$

Alternative I: using the output approach excluding amount of vouchers and social welfare payments or cash transfers

$catasrophiccostsif\frac{\left(m,-,s\right)+n+i}{r}\ast 100>20\%$

Alternative II: using the output approach with asset-based income instead of self-reported income

$catastrophiccostsif\frac{\left(m,-,s\right)+n+i}{a+c+v}\ast 100>20\%$

Alternative III: using the human capital approach

$catastrophiccostsif\frac{\left(m,-,s\right)+n+h}{r+c+v}\ast 100>20\%$

Alternative IV: using the direct cost only

$catasrtophiccostsif\frac{\left(m,-,s\right)+n}{r+c+v}\ast 100>20\%$

where: m = direct medical costs n = direct non-medical costs i = indirect cost as income loss h = indirect cost as product of working hours lost and hourly rate s = reimbursements from private health insurance v = amount from any vouchers received c = amount from any social welfare payments and cash transfers r = Annual self-reported household income a = Annual asset-based household income
