The modified logit model (Amemiya and Nold, 1975) is generalised to the case where the error term is autocorrelated. The
asymptotic distribution (as n →∞ and T →∞) of a feasible GLS estimator of β is derived. Tests of linear restrictions on β and the significance of ρ are presented.
The results of the applied work suggest that the factors which explain the pricing behaviour of manufacturing firms, as reported
in the tendency survey conducted by the Australian Chamber of Commerce and Industry and the Westpac Banking Corporation, include
historical inflation rates of up to 7 quarters and capacity utilisation.

Summary. This paper provides conditions for the almost sure convergence of the least squares learning rule in a stochastic temporary
equilibrium model, where regressions are performed on the past values of the endogenous state variable. In contrast to earlier
studies, (Evans and Honkapohja, 1998; Marcent and Sargent, 1989), which were local analyses, the dynamics are studied from
a global viewpoint, which allows one to obtain an almost sure convergence result without employing projection facilities.

Simple models of local government behavior predict equal effects of private income and unconditional federal grants on local
government expenditures. Numerous empirical analyses, however, find that the effect of grants is larger than the income effect.
We argue that this flypaper effect may be a result of weak political leaderships in multi–issue and multi–party decision–making
environments. In multi–issue institutions, a strong political leadership may reduce inefficiency due to interest group influence
and inter–party bargaining in the local council. Utilizing data for Norwegian local governments in the 1930s, we find that
political strength reduces the size of the flypaper effect. When the local council consists of only one political party, we
cannot reject absence of a flypaper effect, while the flypaper effect is large in fragmented local councils.

An estimation method is presented which compromises robust efficiency with computational feasibility in the case of the generalized
Poisson model. The formal setup is built on flexible nonparametric extensions of the underlying model. The estimation efficiency
is expressed via minimax properties of tests resulting from expansions of estimators. The nonparametric neighborhoods related
to the proposed score function are exemplified and a real data case is analysed. The resulting method balances several qualitative
features of statistical inference: strong differentiability (asymptotic derivations are more accurate), efficiency and natural
model extension (quality of formal basic assumptions). 相似文献

Sequential estimation problems for the mean parameter of an exponential distribution has received much attention over the
years. Purely sequential and accelerated sequential estimators and their asymptotic second-order characteristics have been
laid out in the existing literature, both for minimum risk point as well as bounded length confidence interval estimation
of the mean parameter. Having obtained a data set from such sequentially designed experiments, the paper investigates estimation
problems for the associatedreliability function. Second-order approximations are provided for the bias and mean squared error of the proposed estimator of the reliability
function, first under a general setup. An ad hoc bias-corrected version is also introduced. Then, the proposed estimator is
investigated further under some specific sequential sampling strategies, already available in the literature. In the end,
simulation results are presented for comparing the proposed estimators of the reliability function for moderate sample sizes
and various sequential sampling strategies. 相似文献
