WebMay 26, 2024 · An intuitive explanation: Any smooth function can be locally approximated by a linear function. f ( x) ≈ b + ( x − x) b f ( x ∗) and a = f ′ ( x ∗). When x ∗ is a fixed-point of the equation x = f ( x), we also have b x ∗. So the iterations are approximately. x → x ∗ + a ( x − x ∗) → x ∗ + a 2 ( x − x ∗) → x ∗ ... In domain theory, the notion and terminology of fixed points is generalized to a partial order. Let ≤ be a partial order over a set X and let f: X → X be a function over X. Then a prefixed point (also spelled pre-fixed point, sometimes shortened to prefixpoint or pre-fixpoint) of f is any p such that f(p) ≤ p. Analogously, a postfixed point of f is any p such that p ≤ f(p). The opposite usage occasionally appears. Malkis justifies the definition presented here as follows: "since f is before …

WebEconomic growth with incomplete financial discipline. István Besenyei. 2012. We introduce soft budget constraint and stop-go policy into a stable two-sector AK macro-model. As the extended model does not have any fixed point, we use computer-simulation to examine the dynamic behaviour of the model. We show that depending on the starting ...
