Regression Analysis: Instructional Resource for Cost/Managerial Accounting

Abstract

This paper describes a classroom-tested instructional resource, grounded in principles of active learning and a constructivism, that embraces two primary objectives: ‘demystify’ for accounting students technical material from statistics regarding ordinary least-squares (OLS) regression analysis – material that students may find obscure or overly abstract – and increase student knowledge regarding the use of Excel for cost-estimation purposes. The resource consists of a set of seven student-related files – PowerPoint slides, Word documents, and Excel files – divided into two major parts: four files that deal with simple (i.e., one-variable) linear regression and three files related to the incremental unit-time learning-curve model. A separate Word file, meant for instructors, provides detailed guidance regarding the use of the student-based files. The resource is flexible in that it can be used at both graduate and undergraduate courses in cost/management accounting; customized to meet the needs of individual instructors (coverage of the entire resource requires approximately seven hours of in-class time) and used in conjunction with any cost/management accounting textbook. Throughout the resource many references to related online supplemental materials are provided, including links to relevant online video clips.     

我国上市公司杠杆收购绩效研究

企业资源优化配置,实施并购重组是我国目前资本市场上的一大热点.杠杆收购由于其创新性的并购方式,强大的融资能力,成为近年来在我国并购市场上备受瞩目的商业手段.本文通过对我国上市公司发生的杠杆收购案例进行分析,进一步选用因子分析法对公司杠杆收购绩效进行量化分析,得出结论为：杠杆收购对短期的企业绩效有正向激励作用,但是对长期绩效积极影响不明显,企业总体绩效在杠杆收购第3年后下滑,同时归纳出我国目前杠杆收购融资模式主要集中于商业银行贷款、信托机构融资的方式,融资模式较为局限,现存资本市场条件及政策对杠杆收购绩效有所限制.     

人民币实际有效汇率变动对就业影响的传导渠道分析

当出口在一国经济中占重要地位时,汇率调整就会对就业产生重要影响,在此过程中其传导渠道备受关注。文章构建测算传导渠道的模型,发现:人民币汇率变动会通过出口需求、资源配置和效率渠道对就业产生影响,其中,出口需求渠道的作用最强,效率渠道的作用次之,资源配置渠道的效应最弱。但资源配置渠道的影响效应为正,即汇率升值通过资源配置能带动就业;而出口需求和效率渠道的影响效应为负,即汇率升值将通过出口需求和效率变动减少就业。文章据此提出在当前金融危机冲击下,我国应采取何措施缓解实际汇率变动对我国就业的影响。     

Optimal investment and production decisions and the value of the firm

We explore the effects of uncertainty on a firm that can respond by modifying its investment or production schedule (or both simultaneously) to variations in output price. Investment may increase capacity and/or reduce costs. We consider a firm with finite resources.Our model uses option theory instead of the more traditional net present value framework. One of the early papers using this approach is Brennan and Schwartz (1985) in which an investment project to extract a finite natural resource is valued. In that paper, the value of the firm is a function of two state variables, the finite resource to be extracted (output to be produced in the future) and the commodity spot price. In order to maximize firm value, the manager can respond by modifying one control variable, the production level. In our model we handle instead three state variables (spot price, resources, accumulated investment) and two control variables (production rate and investment rate), and solve numerically.We obtain both the value and the optimal policy of a firm that has investment projects that increase capacity and/or reduce costs and illustrate optimal policies as resources and available investments decrease over the life of the firm. Firms may start by only investing, then invest and produce, to end only producing.We thank Scott Wo, the referee and the editor for their comments and suggestions.

Sharing Demand Information in a Value Chain: Implications for Pricing and Profitability

While it is known that information exchange (IE) in a value chain improves resource coordination, scant attention has been paid to two issues. The first issue is the effect of relative bargaining strengths of the parties on whether and how IE will be implemented. The second issue is whether a resource-based costing system is adequate to motivate the implementation of information exchange. In this paper, we model a value chain consisting of a manufacturer and a retailer, where the retailer gets (private) demand information that has the potential of improving the manufacturers resource decisions. In this model, it is always beneficial for the value chain to implement IE. We show that in a monopsony or in a bilateral monopoly when the retailer has sufficient bargaining power, IE can be implemented if and only if the wholesale price compensates him for the loss of the information rent that he would get without IE. Using this model as the benchmark, we also examine other settings where the retailers have less bargaining power due to competition or size. In such settings, even though the retailers are better informed, the manufacturer can implement the IE regime costlessly and appropriate the information rent partially or fully. In effect, the manufacturer benefits both by improved resource coordination and by reduced payment for information rent. In all these settings, we find the retailer will not be motivated to adopt IE solely by a resource-based costing and pricing system.

A goal programming model for human resource accounting in a CPA firm

Goal programming is a vital technique in reconciling conflicting objectives of job productivity, human resource development, and individual satisfaction. This paper uses a non-monetary approach to human resource valuation by exploring a goal programming model for planning the utilization of interacting human resources. A simulated illustration of the model for a hypothetical CPA firm is described, and the planning alternatives open to the partner-in-charge-of-personnel are shown graphically. The paper concludes with a discussion of extensions of the model.     

Productivity Growth and Sustainability in Post-Green Revolution Agriculture: The Case of the Indian and Pakistan Punjabs

This article attempts to determine the long-term productivityand sustainability of irrigated agriculture in the Indian andPakistan Punjabs by measuring trends in total factor productivityfor production systems in both states since the advent of theGreen Revolution. These measurements over time and across systemshave resulted in three major findings. First, there were widespatial and temporal variations between the two Punjabs. Althoughoutput growth and crop yields were much higher in the IndianPunjab, productivity growth was higher by only a small margin.Moreover, the lowest growth in productivity took place duringthe initial Green Revolution period (as opposed to the laterintensification and post–Green Revolution periods) andin the wheat-rice system in both states. The time lag betweenadoption of Green Revolution technologies and realization ofproductivity gains is related to learning-induced efficiencygains, better utilization of capital investments over time,and problems with the standard methods of productivity measurementthat downwardly bias estimates, particularly during the GreenRevolution period. Second, input growth accounted for most ofthe output growth in both Punjabs during the period under study.Third, intensification, especially in the wheat-rice system,resulted in resource degradation in both Punjabs. Data fromPakistan show that resource degradation reduced overall productivitygrowth from technical change and from education and infrastructureinvestment by one-third. These findings imply the need for policiesthat promote agricultural productivity and sustainability throughpublic investments in education, roads, and research and extension;and that reduce resource degradation by decreasing or eliminatingsubsidies that encourage intensification of inputs.

Public Services Under New Labour: Back to Bureaucracy?

The public service policies of the present Labour Government are assessed against a conceptual model of bureaucracy. In particular, is there evidence of a shift away from the market reforms of the Conservatives, and a move towards bureaucratic methods of resource allocation and service delivery? It is concluded that there is a small, but significant, shift back to bureaucracy: if Conservative policies consisted of 'marketization at the margins', then Labour reforms can be described as 'bureaucratization at the boundaries'. The potential consequences of this change in emphasis are considered.

Inconspicuousness and obfuscation: how large shareholders dynamically manipulate output and information for trading purposes

I model a large shareholder who can affect firm fundamentals. I demonstrate that the large shareholder amplifies the component of his private information that is unforecastable by uninformed traders and thus alters the fundamental value of the firm to facilitate his trading profits: he obfuscates. I then construct a continuous time dynamic version of the model using Fourier transform methods. In the dynamic model, the large shareholder does not just simply amplify the unforecastable part of the fundamental: he also alters its stochastic structure. The model thus marries market microstructure with real resource allocation. There are two consequences: (i) the large shareholder induces the fundamental value of the firm to more closely mimic the noise traders, and (ii) market liquidity is reduced.     

On the differences in measuring SMB and HML in the UK – Do they matter?

The Fama–French (FF) three factor model expands the capital asset pricing model (CAPM) to include two additional factors to the market factor – SMB, employed to capture a firm size effect in returns and HML employed to capture book-to-market effects in returns. In the UK, different researchers use different ways of calculating SMB and HML in the context of empirical applications of the three factor model, or extensions of it, perhaps because they believe the differences in the construction of the SMB and HML factors to be relatively unimportant from an empirical standpoint. We investigate whether indeed factor construction methods are unimportant. Our conclusion is that they do matter.     

Machine learning loss given default for corporate debt

We apply multiple machine learning (ML) methods to model loss given default (LGD) for corporate debt using a common dataset that is cross-sectional but collected over different time periods and shows much variation over time. We investigate the efficacy of three cross-validation (CV) schemes for hyper-parameter tuning and bootstrap aggregation (Bagging) in preventing out-of-time model performance deterioration. The three CV methods are shuffled K-fold, unshuffled K-fold and sequential blocked, which completely destroys, keeps some and completely retains the chronological order in the data, respectively. We find that it is important to keep the chronological order in the data when creating the training and testing samples, and the more the chronological order that can be retained, the more stable the out-of-time ML LGD model performance. By contrast, although bagging improves out-of-time fit in some cases, its effectiveness is rather marginal relative to that from the unshuffled K-fold and sequential blocked CV methods. Substantial uncertainty in relative out-of-time performance remains, however, thus ongoing model performance monitoring and benchmarking are still essential for sound model risk management for corporate LGD and other ML models.     

Optimal Disbursement of a Sunk Resource and Decentralised Cost Allocation

We consider whether the allocation of the sunk cost of a central resource to operating divisions can be consistent with economically optimal resource consumption decisions. When it is recognised that the central resource is scarce, one may, in principle, defend the allocation of sunk cost, if it measures the opportunity cost of usage. However, typically it has been proposed that such allocations are, at best, a proxy for opportunity cost. Applying classical control theory techniques in a wide range of operating environments, we are able to identify cost allocations that exactly equal opportunity cost. Hence, for our model environment, we provide a rationale for sunk cost allocation in terms of guiding optimal decisions, in contrast to the traditional defence in terms of providing a proxy for opportunity cost. We demonstrate clearly how cost allocations are related to opportunity costs, and identify the circumstances under which the allocation of full costs or alternatively a fixed proportion (related to acquisition conditions) of costs, results in the implementation of economically optimal resource consumption decisions.     

Applying a factor copula to value basket credit linked notes with issuer default risk

This paper explores a reasonable coupon rate for basket credit linked notes (BCLN) with issuer default risk. Based on the one factor Gaussian copula model, this paper proposes three methods of incorporating issuer default into BCLN pricing. Numerical results indicate that issuer default risk impacts BCLN coupon rate. Furthermore, coupon rate differs with changes in correlation structure among the three methods. One of the three methods is ultimately identified as the most suitable.
