生产技术的跨期结构：检验 putty-clay 假说的模型AI 解读

This paper develops an econometric model of production technology in terms of the ante-ex description of production possibilities. Ex ante and ex post substitution characteristics are allowed to differ from one another and parametric representations are derived which provide arbitrary second-order approximations to the true underlying characteristics. Nested in the maintained model are the specialized putty-putty, puttyclay, and structures of technology; and hypothesis tests…

基于选择结果抽样的选择概率估计AI 解读

Ti-H CONCERN of this paper is the estimation of the parameters of a probabilistic choice model when choices rather than decision makers are sampled. Existing estimation methods presuppose an exogeneous sampling process, that is one in which a sequence of decision makers are drawn and their choice behaviors observed. In contrast, in choice based sampling processes, a sequence of chosen alternatives are drawn and the characteristics of the decision makers selecting those…

关于分布滞后、预测与信号提取的说明AI 解读

A wide variety of economic models include as explanatory variables either expectational variables or variables representing the result of some decision-making process. The first category includes both expectations about the future values of variables, e.g., next period's sales, the level of unemployment two quarters ahead, etc. and other subjective variables such as permanent income or the "normal" level of prices and interest rates. Examples of the second type are "desired"…

时间序列与截面数据的合并估计AI 解读

PROGRAMS ARE AVAILABLE to facilitate calculation of least squares and instrumental variable coefficients and related statistics from data consisting of time-series observations for each of several cross-sectional units.' The (FORTRAN) programs2 must be used with the SPEAKEASY/FEDEASY processor3 and take the form of three FEDEASY commands that (1) form a moment (cross product) matrix from an arbitrarily large number of observations (CPMATRIX), (2) calculate least squares and…

多重时间序列分析与计量经济模型的最终形式AI 解读

Univariate autoregressive moving average models for the endogenous variables of a dynamic simultaneous equations system can be interpreted as a form of solution of that system. This paper considers the interrelationships between the various representations of the system, and develops joint estimation and model selection procedures for the multiple time series model which arises as a multivariate representation of the individual autoregressive moving average models. A test of…

稳定分布滞后的存在性AI 解读

This paper attempts to determine conditions under which distributed lag analysis is appropriate. Results indicate that lag functions are stable and linear under fairly general (but constant) objective criteria and decision constraints as long as the underlying economic environment is characterized by a stationary Gauss-Markov process, and observed environmental variables are Gaussian perturbations of that process. The results appear particularly useful for specifying the lag…

扰动方差不等时两组线性回归系数相等的检验AI 解读

is misleading if o-2 $ o-2 and n, and n2 are both small, where Y, and Xi are ni x 1 and ni x k observation matrices, ,li is a k x 1 coefficient matrix, and ei is an n, x 1 error matrix for i=1,2. A valid asymptotic test may easily be obtained by regarding (1) and (2) as seemingly unrelated regression equations. In this paper we establish a small sample test which may readily be extended to a test of some of the coefficients in the two regressions.

多元线性回归模型中假设检验准则的冲突AI 解读

This paper surveys alternative testing criteria in the linear multivariate regression model, and investigates the possibility of conflict among them. We consider the asymptotic Wald, likelihood ratio (LR), and Lagrange multiplier (LM) tests. These three test statistics have identical limiting chi-square distributions; thus their critical regions coincide. A strong result we obtain is that a systematic numerical inequality relationship exists; specifically, Wald , LRa LM.…
