“…These include looking at the impact of unemployment insurance on the reservation wage-levels, and thus on the average duration of unemployment (Feldstein and Poterba, 1984); the effect of the benefit-income ratio (replacement ratio) on the unemployment rate and the average duration (Chapin, 1971;Maki and Spindler, 1975;Cubin and Foley, 1977;Nickell, 1979;Wunnava and Henley, 1987); the effect of unemployment insurance on the quit rate (Hamermesh, 1979); and the differential impact of unemployment insurance on industrial sectors (Deere, 1991). Some of the studies, such as that of Maki and Spindler (1975) have explored the possibility of potential feedback effects between the replacement ratio and the unemployment rate. The rationale for doing this is that during periods of high unemployment, incomes may be lower which would cause the replacement ratio to be higher, allowing for possible simultaneity between the unemployment rate and replacement ratio.…”
