Hi, I'm sure x_t is a decreasing sequence while y_t is an increasing one. It feels like it should be simple to prove, but I just can't do it. Any suggestions would be great!
Thanks,
Peter
x_t and y_t are defined iteratively by two equations:
1. y_(t+1) = bq x_t + b(1 - q) y _t
2. f[x_(t+1)] = bqf[x_t] + b(1 - q) f[y _t]
IE
2B. x_(t+1) = f^(-1)[bqf[x_t] + b(1 - q) f[y _t]]
Other conditions:
1. f[x] is decreasing and concave
2. x_0 = 1
3. y_0 = 0
4. 0 < q < 1
5. 0 < b < 1
6. f(0) = 1
7. f(1) = 0
Thanks,
