We see the co-existence of imported and traditional, both idealistic and realistic models of performance management as problematic. Such performance management models are based on different institutional logics that are the taken-for-granted rules guiding behavior of field-level actors, and related practices that predominate in an organizational field. These logics help to explain connections that create a sense of common purpose and unity within an organizational field (Scott, 2001; Kitchener, 2002). The purpose of this paper is to analyze and illustrate how institutional pressures for management accounting change are formed. Most studies on change and stability of management accounting pay little attention on how institutional pressures for accounting change are formed, especially on the political field level. Our study demonstrates how various actors at the political field level participate in creating institutional pressures in diverse and sometimes contradictory ways. Drawing on archival data and 20 interviews with public officials, we seek to illustrate how different organizational field-level actors' views on implementing cost accounting differ, and how these views have influenced the outcome of cost accounting development in the Finnish Defence Forces. Our results suggest that contradictory institutional logics exist in relation with Finnish central government management-by-results, performance management and cost accounting systems. A value-for-money ideology in the armed forces sector (see e.g., Gr6nlund & Catasus, 2005) at times seems to challenge and even contradict the "legalistic" tradition of developing cost accounting that conforms to budgetary laws and statues. Similarly, the New Public Management based performance prism model (Fryer, Antony, & Ogden, 2009; Neely, Adams, & Crowe, 2001), when implemented at a local level, seems to conflict with notions common in accounting literature, according to which management accounting systems should be aligned with organizations' strategy and structure (see e.g., Abemethy, Lillis, Brownell, & Carter, 2001).展开更多

It establishes a linear cost model to find unit cost. Linear goal programs assume a direct relationship between independent variable and dependent variable. Dependent variable of linear model is unit cost. Independent variables are cost accounting variables. They are supply cost, labor cost, and administration cost. This study assumes a direct relationship between supply-labor-administration costs and unit cost. Therefore, it establishes a linear cost model. The major research question of this study is to apply linear goal programming to cost accounting. The goal of this linear program is to find unit cost of product. This study uses quantitative method and human capital method. The main research result is linear costing model itself.展开更多

Any investment in acquisition of arms and military equipment (AME) due to financial significance does not allow mistakes in decision making. Qualitative analysis of cost of assets through the entire programmed lifecycle is a complex multi-disciplinary and multi-criteria problem whose solving requires application of the model multi-criteria optimization. In our operational practice thus far, solving the said problems there wasn't enough the model multi-criteria optimization so the optimal results were lacking. In this paper investment process of AME in the MoD and SAF was analyzed, from the point of cost treatment in the process, its flaws have been pointed out and a more comprehensive - integrated approach has been suggested.展开更多

This analysis is based on the study carried out within the city organizations in 2011. The questionnaire drawn up by the authors includes several questions about the current management accounting tools of the city and their development and support needs. The authors also add some questions related to the sustainability reporting, which is obligatory for the city as one of the members of the Aalborg Charter. The quantitative methodology was used. The authors' conclusion is that the level of the managerial accountability of the Estonian municipality is increasing and its sole economic focus is changing to a broader perspective. According to the findings of the study, the authors argue that both management accounting principles and sustainability principles are coming closer together. By using Talcott Parsons' adaptation, goal attainment, integration, and latency (AGIL) paradigm, the authors point out four critical components for implementing the sustainability reporting into a management accounting system. The results of this study highlight the role of values in the management accounting development, which is in harmony with the AGIL paradigm.展开更多

Findings shed light on the role of the cost accounting system in price assessment: It outlines new opportunities for the identification of the service mix offered as well as for price optimization. Because private companies provide services both within the public system--where the National Health System (NHS) provides fixed reimbursement fees--and within the private system--where prices are defined by each company. Accurate cost information is extremely important to support managers in the analysis of the service mix profitability offered in each system. For the business segment in which companies do not have flexibility in setting prices, cost information enables managers to identify services which may present profitability problems. For the business segment where price flexibility exists, cost information supports the identification of pricing errors so that charges can be better defined.展开更多

This debate presents a major challenge for FVA going forward and standard setters' push to extend FVA into other areas. In this article, we highlight three important issues as an attempt to make sense of the debate. First, much of the controversy results from confusion about what is new and different about FVA. Second, while there are legitimate concerns about marking to market (or pure FVA) in times of financial crisis, it is less clear that these problems apply to FVA as stipulated by the accounting standards, be it IFRS or U.S. GAAP. Third, historical cost accounting (HCA) is unlikely to be the remedy. There are a number of concerns about HCA as well and these problems could be larger than those with FVA.展开更多

The effect of CMS design effectiveness on cost information quality is investigated. Moreover, the effect of cost information quality on business success is investigated. Furthermore, executive management support and cost accountant competency are assumed to become the antecedents of CMS design effectiveness. Electronics manufacturing businesses in Thailand are samples of the research. A mail survey procedure via the questionnaire was used for data collection from accounting controllers. The results indicate that CMS design effectiveness has a positive significant effect on cost information quality. Moreover, cost information quality also has a positive significant effect on business success. Additionally, both executive management support and cost accountant competency have a positive significant effect on CMS design effectiveness.展开更多

To be able to persist in the open competition, entities are forced to invest increasingly in the professional training of their employees. Inconsistent with this rising importance is the prohibition to capitalize professional training cost according to international accounting standards (IAS) 38.69 (b). Highly qualified employees ensure competitive advantages and thus lead to an increase in shareholder value. Regarding the financial statement as a primary source of information, it does not seem reasonable to leave such a valuable resource completely unnoticed in the balance sheet. Consequently, a truthful representation of a firm's asset should take training costs into account. This article pleads for a limitation of this general legal prohibition and analyzes under which premises those expenditures for training can comply with the common criteria of capitalization according to IAS 38.展开更多

A 22 factorial planning has been used to evaluate the influences of alcohol/oil and reaction time on the biodiesel production yield. The optimal condition to produce the biodiesel has been found by use of the response surface methodology and analysis of variance to obtain the fitting model. This study was conducted in Campinas city, Brazil, where were collected the waste oil. An analysis of ecological cost also has been developed. Cooking oils collected from Campinas homes were mixed with ethanol in planned proportions (1:9, 1:7 and 1:5) and were transesterified at 60 ℃ and planned reaction times (30, 60 or 90 min), in order to obtain biodiesel, using 0.1% NaOH as a catalyst. The results of the physical-chemical analyses demonstrated that the biodiesels obtained possessed characteristics close to those required by Brazilian standards. This fuel could be used in fleets of buses, trucks and machines, or even sold to fuel distributors, which results in a solving between US$0.8 and US$4.5 millions. Thus, Campinas would gain environmental credits and become a sustainable city.展开更多

文摘This paper aims to find unit cost of a product for firms. It establishes a linear cost model to find unit cost. Linear goal programs assume a direct relationship between independent variable and dependent variable. Dependent variable of linear model is unit cost. Independent variables are cost accounting variables. They are supply cost, labor cost, and administration cost. This study assumes a direct relationship between supply-labor-administration costs and unit cost. Therefore, it establishes a linear cost model. The major research question of this study is to apply linear goal programming to cost accounting. The goal of this linear program is to find unit cost of product. This study uses quantitative method and human capital method. The main research result is linear costing model itself.
