作为一种沿用多年的发出存货计价方法,后进先出法曾经被视为先进先出法缺陷的完美补充。近年来,包括我国在内的各国会计准则又先后将其舍弃,其中的原因是什么?文章拟从经济学视角,对其进行探讨,以求得出有说服力的解释。 相似文献

This article describes the process for preparing a survey, which will be used to measure relevant variables, which are involved
in a study of training needs in a Spanish sports organisation. The variables which have been considered are: problems and
difficulties in carrying work of specific positions; “strong points” in carrying out this work; usefulness of the training
received in facing and solving the above-mentioned problems and difficulties; usefulness of the training received in acquiring
and strengthening these “strong points” in carrying out work; opinion and suggestions with respect to future training. Due
to the applied nature of the study, a data collection methodology was designed which was based on interviews and group discussions
with a representative sample of workers. Finally, the predictive capacity of perception, which workers have, of their motivation
at work was clearly shown in order to then identify different attitude and conduct patterns. 相似文献

We solve the stochastic neoclassical growth model, the workhorse of modern macroeconomics, using C++14, Fortran 2008, Java, Julia, Python, Matlab, Mathematica, and R. We implement the same algorithm, value function iteration, in each of the languages. We report the execution times of the codes in a Mac and in a Windows computer and briefly comment on the strengths and weaknesses of each language. 相似文献

Raising the bar (5). Spatial Economic Analysis. This editorial summarizes and comments on the papers published in this issue 12(1) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper examines the impact of the level of education on the decision to migrate and finds that it is approximately twice as large if both variables are modelled simultaneously. The second paper is one of the first papers to introduce a spatial component to models of international environmental agreements and to develop an exciting overlap with New Economic Geography. The third paper provides a tool, applied to Beijing, with which urban economic planners can investigate the role of variation and selection mechanisms in cluster development and identify possible paths of growth. The fourth paper contributes to the existing literature on retail geography by examining the role of consumption possibilities as an urban amenity. The fifth paper develops a Bayesian estimator of a linear regression model with spatial lags among the dependent variable, the explanatory variables and the disturbances. Finally, the sixth paper develops a semi-parametric generalized method of moments (GMM) estimator for a spatial autoregressive model with space-varying coefficients of the explanatory variables and a spatial autoregressive coefficient common to all units. 相似文献

Raising the bar (6). Spatial Economic Analysis. This editorial summarizes and comments on the papers published in issue 12(4) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper addresses the question of whether ‘jobs follow people’ or ‘people follow jobs’. The second paper develops a new methodology to determine functional regions. The third paper is a major contribution to the growing literature on new modelling approaches and applications of disaster impact models. The fourth paper focuses on the costs and benefits of higher education. The fifth paper develops a two-step procedure to identify endogenously spatial regimes in the first step using geographically weighted regression, and to account for spatial dependence in the second step. Finally, the sixth paper estimates a dynamic spatial panel data model to explain house prices and to show that restricted housing supply in the city of Cambridge, UK, has some undesirable labour market effects. 相似文献
