Kiefer introduced the Fibonacci search as a direct optimal method. The optimality was proved under the restriction: the total number of tests is given in advance and fixed. To avoid this restriction, some different concepts of optimality were proposed and some corresponding optimal methods were obtained in [1], [2], [5] and [6]. In particular, the even-block search was treated in [1]. This paper deals with the odd-block search. The main result is Theorem 1.15.展开更多

It is shown that the stationary equilib- rium is efficient if and only if the Hosios condition holds no matter whether learning is about finn-specific human capital or about general human capital. However, the stationary equilibrium can never be efficient if externalities exist from unemployment. In contrast, even with externalities, the stationary equilibrium can be efficient under some modified Hosios condition if there is no uncertainty （standard Mortensen and Pissarides （1994）-type equilibrium search environment）. The key intuition is that the equilibrium can only be efficient if firm-worker matching is formed and terminated efficiently.展开更多
