• A household spends their income on two goods: "other goods" and "travel". "Travel" stands for regional travel undertaken by a household within their own state.
• All households have "usually shaped" or "well-behaved" preferences between these goods.
• Income of any household is denoted as Y and it exceeds $400.
• The price of a unit of other goods is $1 and the price of a unit of travel is $p per unit in each state.
• Other goods and travel are homogenous and divisible goods that can also be consumed in fractional quantities.
• All households treat other goods and travel as normal goods and both have positive income elasticities

Victorian Regional Travel Voucher Scheme: A voucher recipient gets $200 reimbursement as long as they spend at least $400 on travel. South Australian Regional Travel Voucher Scheme: A voucher recipient gets a $50 voucher to spend on regional travel.
