HOW IT WORKS
In each round, 159 households (represented by turtles) consume and interact with each other to simulate everyday economic activity. There are 3 different local socio-economic statuses (POOR, MIDDLE, and HIGH) and each household’s monthly expenditure can be controlled by MONTHLY-EXPENDITURES according to its social status. The number of households with a social-status is calculated by its income in each moment.
The Households can earn seasonal income or earn money doing temporary work through EXTRA-INCOME slider. They also can have unforeseen expenses through the EXPENDITURE-CRISIS switch.
When a household is run out of money it can borrow money trough its interpersonal, ethnic or pawnshop network connections. You can turn-on or turn-off each of this loan with the switch.
Households with a negative balance can borrow money and household with a positive balance lend money through the existing interpersonal loan network. Lenders can decide whether they would like to lend money or do not want to in the ethnic relation based loan network. Pawnshop lends money if the household has an existing relationship with it.
One household can only borrow once from each lender and can not borrow another loan while it doesn’t repay its existing loan.
