课堂传播中学生主体对知识信息的需求特征及其把握

课堂传播活动中学生对知识信息的需要系统,与外在环境和社会发展处于相互作用之中,既是动态的,也是分层的;其主导需要对社会具有提醒作用,并在其群体内部引领走向;其易于受到具有流行性特征的社会文化心理的＂干扰＂,必须予以引导和纠偏。     

PER UNIT COST ALLOCATION OF INVESTED CAPITAL WITH ANTICIPATED NON-LEVEL PRODUCTION: THE CASE OF EXTRACTIVE INDUSTRIES

The concept of equivalent annual annuity (EAA) has long been used as a method of costing recovery of invested capital and the required return on invested capital over the productive life of a capital project. Academic texts almost universally use EAA methodology with level payment streams (annuities) to allocate capital costs. We develop a methodology for allocating capital costs evenly over each unit of production for projects with anticipated non-level production. This methodology uses a modified EAA approach that allows non-level annuity payment streams. Capital cost allocation is an important component in computing the value of extracted minerals for severance tax purposes; however, many firms and state and federal agencies use ad hocdepreciation schedules to allocate these costs. Ad hocdepreciation methods such as modified accelerated cost recovery system (MACRS) may be appropriate for income tax purposes but are inconsistent with commonly found requirements that severance taxes “shall be assessed on the wellhead or mine mouth fair market value.” The modified EAA approach provides a straightforward alternative that is based on sound financial methodology.

The Under-Exploitation of Natural Resources: A Model with Overlapping Generations*

It is well known that competitive markets may fail to generate an optimal rate of extraction of a natural resource-stock. The barrier to optimality may be uncertainty about tenure, commonality of property rights in the resource, or uncertainty about the extent of the resource. In all these cases, suboptimality takes the form of over-extraction. We draw attention to an additional source of suboptimality. In an economy with overlapping generations, the resource-stock plays the double role of repository of savings and source of productive inputs. The decline in the supply of the resource-stock may eventually force its price so high that it ceases to perform its second function. Extraction comes to an end even though the resource has a positive marginal productivity in producing consumption goods. This is inefficient, hence suboptimal. This time, however, suboptimality takes the form of under-extraction.

Non-stationary Hours in a DSGE Model

The time series fit of dynamic stochastic general equilibrium (DSGE) models often suffers from restrictions on the long-run dynamics that are at odds with the data. Using Bayesian methods we estimate a stochastic growth model in which hours worked are stationary and a modified version with permanent labor supply shocks. If firms can freely adjust labor inputs, the data support the latter specification. Once we introduce frictions in terms of labor adjustment costs, the overall time series fit improves and the model specification in which labor supply shocks and hours worked are stationary is preferred.
