Health shock and preference instability: assessing health-state dependency of willingness-to-pay for corrective eyeglasses

Table 3 Cost and Consumer Surplus Simulated from the Suggested Demand Curves

Case	[1]	[2]	[3]	[4]
Case	Slope	Intercept	Consumer Surplus	Cost
Unmatched Without-Health-Shock Group	− 1292.7	1150.8	94.1	250.9
Matched Without-Health-Shock Group	− 1211.0	1220.9	131.1	305.9
With-Health-Shock Group	− 1077.3	1231.5	153.0	350.3

(a) Slopes and intercepts were estimated by fitting linear regressions for each of the demand curves demonstrated in Fig. 2, (b) Consumer surplus is obtained with an assumption of market equilibrium at the average purchasing price of BDT 657, (c) Column 4 of this table shows the average cost incurred at equilibrium conditions with the three different demand curves presented in Fig. 2, (d) Fig. 3 graphically demonstrates the consumer surplus calculation
