Auditors need to feel comfortable when signing the audit in order to produce comfort to society. Today, most companies use complex IT-systems that require that an IT-audit is performed. Rarely auditors possess the sufficient knowledge to perform the IT-audit and therefore an external part of the audit team is involved, namely IT-auditors. It can therefore be problematic for the auditors to ensure the quality of this part of the audit. In this thesis we aim to widen the understanding of how IT-auditors affect how auditors experience that they become comfortable. To investigate the addressed problem the following research question is asked: How do financial auditors experience that they become comfortable with IT-auditors? Ten auditors were interviewed on how they experience the different senses of the Comfort theory to become comfortable. With these senses as background, the study’s aim is to gain a perception of how auditors in Sweden perceive that they become comfortable with IT-auditors, which makes the auditor comfortable to sign the audit. The conclusions are that certain characteristics, such as technical and social skills together with good communication and understanding of the IT- auditors work is perceived as important factors for auditors to become comfortable

Climate change constitutes one of the greatest challenges facing the world today, as it will influence the way we live and work in future decades. Excessive greenhouse gas (GHG) emissions are recognized as the key contributor to climate change, and the construction sector has an indispensable role to play in emission reduction, as building facilities are energy- and emission-intensive to construct and operate. Previous research indicates that up to 30 percent of buildings’ lifecycle emissions can be minimized through the careful selection of low-carbon materials. Although building environmental assessment (BEA) tools have been widely used in identifying and mitigating the lifecycle environmental impacts of building facilities, the existing BEA tools provide no rigorous regime for assessing the embodied GHG emissions of building materials. Therefore the aim of this research is to bridge the research and practical gaps by developing an integrated BEA assessment model that comprehensively audits and benchmarks the embodied GHG emissions of building materials at product level. The research began by examining the limitations of current BEA tools, in particular their means of evaluating the embodied GHG emissions of buildings. Then, an embodied GHG emissions evaluation module model under an existing BEA scheme was proposed. The proposed model comprised (i) product category, (ii) product-based GHG auditing framework, and (iii) emissions benchmarking measure. After that, a thorough review of the relevant literature and international classification systems was carried out to establish a systematic product categorization regime for building materials. An auditing framework comprising system boundary, process map, emission sources, and a carbon auditing tool in Microsoft TM Excel has been developed by reviewing international standards on product carbon footprint assessments and eliciting knowledge from domain experts through a series of interviews. The emission benchmarks for each product category have been determined through the application of fuzzy set theory to facilitate easy comparison and decision-making. Finally, the developed product categorization regime, GHG auditing framework, and benchmarks were validated through a Delphi study, a discussion of which concluded the thesis. The research outcomes confirm that the GHG emissions embodied in a building facility can be meticulously analyzed and integrated into the BEA. The research also improves the understanding of how the materials’ embodied emissions can be accurately calculated at the product level. More importantly, it enhances existing BEA tools by incorporating embodied GHG emissions into the analysis, thus makes the lifecycle emission assessment of building facilities possible. The proposed integrated BEA model will enable clients and design teams to minimize the carbon footprints of buildings and assist users and the general public in identifying green building facilities. The originality of this research lies in the establishment of a set of emissions benchmarks for five most emission-intensive building materials using fuzzy set theory. These benchmarks provide a seamless platform allowing the assessment of materials’ embodied emissions to be integrated with the existing BEA model, thereby not only encouraging the adoption of low-carbon building materials but also fostering ongoing product carbon footprint reductions. / published_or_final_version / Civil Engineering / Doctoral / Doctor of Philosophy

The collection of taxes is something that affects almost every entity in society and often stir up heated feelings. Recent legislative changes have been made in Sweden to adjust to regulations in the European Union. These changes included the abolishment of mandatory auditing for small companies in 2011, leading to heavy debate regarding its effect on tax reduction. Has tax reduction increased when smaller companies are no longer under as heavy surveillance as in the past or is the effect negligible? This is the question that this thesis is trying to answer, namely: is there a connection between being audited and the level of tax reduction, measured as the effective tax rate, in which small Swedish companies partake in? Most of the previous research in the field is sparse when it comes to the effect this might have in the specific conditions of the Swedish market. These studies have mainly been conducted in an American setting and focuses either on large corporations and their reduction of tax liability or attempt to connect the characteristics of auditors with tax evasion. Some studies have been made in Sweden, dealing briefly with the matter but these studies have bypassed the connection between being audited and the level of tax reduction. With tax authorities trying to find new methods to refine their profiling of companies which reduce their tax liability, the thesis fits in well as an addition to both theory and practice. We have tested this connection by conducting a semi-quasi ex post facto experiment using a dataset containing annual reports from all small companies in the restaurant industry which is seen as the industry in which companies are most prone to tax reduction according to Swedish authorities (Skatteverket, 2014, p. 60-61). The dataset has then been altered in accordance with the studies by (Guenther 2014; Bianchi et al. 2014; Dalbor et al. 2004) which included winsorizing, cropping and removal of missing data. The studies of (Bianchi et al. 2014) and (Dalbor et al. 2004) were also used to form the control variables for the study. After the dataset was deemed fit for testing, STATA was used to statistically test the data. Initial results seemed to indicate that there was a positive significant correlation between being audited and the level of tax reduction of the company. However, the results of the propensity score matching based on company size indicated that the association was heavily reliant upon company size. We thus concluded that we cannot prove a statistically significant relationship between a company being audited and its level of tax reduction in the setting of our study. The implications of this finding are several. It helps to build onto existing knowledge regarding auditing’s effect on taxes paid as well as providing the tax authorities in Sweden with an insight into what indicators to use when streamlining their operations. Furthermore, it may add new arguments to be presented in the debate that has taken place in Sweden over the recent years following the legislative changes.

Thesis (MTech. in Internal Auditing) / This study provides an analysis of the role of internal auditing in the organizational performance of the Rwanda Revenue Authority, and aim to show th importance of internal auditing within the organization.

Certifiers have a crucial role in facilitating effective communication in the online and the traditional world. As a way of generating statistically meaningful information, certification has been adopted in financial statements evaluation and more recently in various online communities as well. This dissertation examines three related issues along this common theme: online reputation market, moderation in user-generated content, and strategic communications in the market for certifications, and consists of three essays. The first essay analyzes the impact of various dispute mechanisms on online identity trading. Online identities with a good reputation profile is a valuable and tradable asset. However, with free identity creation, there is room for low quality sellers to free-ride high quality sellers. When there is a lack of incentive for sellers to maintain a good reputation, identity trading becomes ineffective. This essay focuses on the role of an auditing system, such as eBay dispute center, and shows that even a small amount of objective information from the auditors can reverse the negative result and sustain reliable reputation and identity trading. The second essay investigates the impact of moderation on the quality of information in an user-generated content (UGC) environment. In most UGC communities, content contributors have incentive to publish biased or false information. For example, companies hire people to write positive reviews about themselves. This essay establishes a framework for the mechanism design of moderation, and provides insight on how to optimally allocate moderation resource. The third essay examines a market for certification and certifiers' strategic reporting behaviors. The central question is how to induce certifiers to provide statistically meaningful information to investors when they are paid by their client firms. We provide insights on how certifier competition plays an role in firms' certifier choice, how certifiers degrade their accuracies to achieve maximum profit, and how the legal environment impacts the information quality. / text

The purpose of this dissertation is to examine the informational role of audit client (i.e. firm) reputation in the auditor switching and retention decision. I perform an experimental examination of an analytical model, prescribing the optimal choices made by firms in the decision to retain or switch auditors without considering firm reputation. Using an experimental markets approach, I provide evidence of the market reaction to a firm's switch/retention decision under two alternative treatments. In the first (baseline) treatment, an explicit test of the analytical model, firms do not incur reputation effects when making the decision to switch or retain auditors. In the second treatment, firms consider market perceptions of opportunistic auditor switching and retention and the potential effects on the firm's reputation.The choice of auditor switching and retention is a significant component of the firm's corporate governance structure. I precisely measures reputation formation and its impact on this specific governance decision by the inclusion of prior period auditor switch/retention decisions made by firms in reputation treatment conditions. Prior archival research has demonstrated a link between auditor quality and earnings quality. These studies suggest that the retention of a high-quality auditor, or dismissal of a poor-quality auditor, can signal high quality earnings to the market. The converse is also suggested; retention of a poor-quality auditor, or dismissal of a high-quality auditor, can signal poor earnings quality. The decision to retain or switch auditors is made annually by firms who have superior information over their auditors and investors. In the short run, the decision to retain or switch auditors offers a temporary signal which the market may not clearly price. However, including the firm's track record of auditor switching and retention decisions among auditors of differing quality allows for the development of a positive or negative reputation on this portion of corporate governance.The results presented provide evidence of the model's descriptive validity for the firm's optimal choices and related market reaction to the auditor switching decision for a finite time horizon. Additionally, the study examines the market reaction to a firm's reputation on the auditor switching and retention decision.

This dissertation develops variants of the well-known Hotelling’s location model to examine the nature of competition in the audit market where audit firms make strategic specialization and pricing decisions. In a multi-period spatial oligopoly model of auditing competition, audit firms obtain market power through their service specialization with respect to client characteristics relevant to audit production. This market power allows audit firms to price discriminate among clients. Competition among audit firms is localized: an audit firm optimally charges a client, to whom it has the lowest auditing cost to serve, the marginal auditing cost of the second lowest-cost audit firm. These equilibrium audit firms’ pricing strategies result in an allocation of clients’ surplus and audit firms’ profits that lies in the core of the economy. The existence of a specialization-pricing equilibrium is also established. In equilibrium, given its rivals’ specializations, each audit firm’s profit is maximized by choosing a specialization that maximizes the social welfare (the sum of clients’ surplus and audit firms’ profits). Moreover, audit firms never choose the same specialization in equilibrium. Instead, in order to earn rents as ‘local monopolists’, audit firms differentiate themselves from each other. This result is consistent with a widely held notion that audit firms search for ‘niche’ markets, such as industry specialization, to increase their profits. The dissertation then focuses on a two-period spatial duopoly model in which the market power created by audit firm specialization is now further fortified by the presence of auditors’ learning and clients’ switching costs. In this case, audit firms optimally price discriminate among clients by offering them ‘specialization-and-relationship-specific’ audit fee schedules. The practice of ‘low-balling’ is found to be a natural consequence of the competition among audit firms. However, low-balling occurs only in a certain market segment where audit firms compete quite fiercely. The analysis also demonstrates how equilibrium audit fee schedules, audit firms’ specializations and profits, clients’ surplus, and social welfare depend on the auditing costs, the learning rate, and the switching costs. Some interesting policy implications are illustrated. Finally, the model is used to analyze the impact of banning audit firms from the practice of low-balling. It is demonstrated that even though a policy of banning low-balling always reduces competition, it improves social efficiency in some cases.

This study investigates whether auditors respond to earnings management pressure created by analyst forecasts. Analyst forecasts create an important earnings target for management, and professional standards direct auditors to consider how this pressure could affect their clients. Using annual analyst forecasts available during the planning phase of the audit, I examine whether this form of earnings management pressure affects clients’ financial statement misstatements. Next, I investigate whether auditors respond to earnings forecast pressure through audit fees and reporting delay. I find that higher levels of analyst forecast pressure increase the likelihood of client restatement. I also find that auditors charge higher audit fees and delay the issuance of the audit report in response to pressure from analyst expectations. Finally, I find that when audit clients are subject to high analyst forecast pressure, a high audit fee response by auditors mitigates the likelihood of client misstatements.

Bakgrund: År 2006 så initierade regeringen en utredning gällande slopandet av revisionsplikten i Sverige, som en del i att anpassa sig till EU:s direktiv. Regeländringen gick igenom år 2010 och små aktiebolag i Sverige fick möjligheten att välja bort revision. Efter slopandet av revisionen har diskussioner angående en ytterligare harmonisering mot det högre gränsvärdet i EU förts. Detta ledde in oss på forskningsfrågorna: Hur kan intressenter i Sverige påverkas av en eventuell framtida höjning av gränsvärdet? Vilka möjligheter har intressenterna att anpassa sig till effekterna av en höjning av gränsvärdet? Syfte: Syftet med studien är att undersöka de effekter en höjning av gränsvärdet för revision har för de tre signifikanta intressenterna; kreditgivare, Skatteverket och aktiebolag. Detta gör vi genom att jämföra förväntade effekter med de verkliga effekter som uppstod i EU länderna Storbritannien och Danmark. Vi ämnar att analysera tre intressenter som berörs av regeländringen. Den här studien fokuserar på hur intressenterna har påverkats i respektive land för att sedan bidra med ny kunskap om intressenters påverkan av revisionsplikt i Sverige inför en framtida höjning. De intressenter som undersöks i studien är kreditgivare, Skatteverket och aktiebolag. Metod: I vår studie har vi använt oss av kvalitativ metod och samlade in större delen av vårt data genom tidigare rapporter, utredningar och undersökningar från Sverige, Danmark och Storbritannien. Dessa har kompletterats med expertutlåtanden från två personer från Svenskt Näringsliv och Skatteverket. Slutsats: En höjning av gränsvärdet för revisionsplikten kommer att påverka vår studies intressenter på olika sätt. Ingenting i de rapporter vi tagit del av tyder på att skattebortfall kommer att öka tillsammans med en höjning. Inte heller Skatteverkets legitimitet och relationsberoende kommer påverkas nämnvärt av en höjning. Kreditgivare kommer vid förändringen uppleva en ökad osäkerhet vid kreditgivning. De kommer i högre utsträckning behöva ställa krav på de större aktiebolagen som väljer bort revision. Den direkta påverkan för aktiebolagen är att ett större antal aktiebolag kommer få möjligheten avstå från revision. En stor del av de större aktiebolagen som kommer omfattas av en höjning av gränsvärdet, kommer att fortsätta använda sig av revision trots valmöjligheten att välja bort det. Men dessa måste hitta nya metoder för att minska osäkerhet som intressenter kan känna när aktiebolagen väljer bort att revidera deras finansiella information. / Setting: In the year of 2006 the Swedish government initiated an investigation concerning the repeal of the mandatory auditing in Sweden, as a start of an adaption towards the EU directives. The repeal of the mandatory audit legislation was passed in 2010 and small companies in Sweden got the opportunity for audit exemption. After the repeal of the mandatory audit, discussions started whether Sweden should raise the threshold of the audit exemption or not. This leads us into the problem definition: How can the stakeholders in Sweden be effected by a raise of threshold of the audit exemption in the future? What opportunities does the stakeholders have to adapt to the effects of a raise of threshold? Purpose: The purpose of this study is to examine what effects a raise of threshold for auditing has on our community and its stakeholders. We compare the expected effects with the real outcome of effects in the EU-countries Great Britain and Denmark. We intend to analyze the three stakeholders that is among the affected of the legislation change. Our focus in this study is to find out how stakeholders are affected in each of every country listed above and contribute with new knowledge regarding stakeholders’ impact by the mandatory audit in Sweden for a future raise of threshold. The stakeholders being examined in this study is creditors, the Swedish tax authority and small companies. Method: In this study we used a qualitative method and the major part of our collected data is from earlier reports, investigations and studies from Sweden, Denmark and Great Britain. These was supplemented with statements from two experts, one of them representing Svenskt Näringsliv and the other one representing the Swedish tax authority. Conclusion: A raise of threshold for the mandatory audit will affect the stakeholders of our study in different ways. None of the reports presented in this study shows that the tax loss will increase together with a raise of threshold. Nor will the Swedish tax authority’s legitimacy- and relationship-dependence be affected substantially. Creditors will experience increased insecurity regarding lending and financing. They will in higher extent need to set demands on bigger companies that opt out auditing. The direct effect on companies will be that a greater proportion of bigger companies will be able to opt out auditing. A greater proportion of these bigger companies that will be a subject of the raise of threshold, will continue using audit although the opportunity to opt out. These will have to find new methods to decrease insecurity that stakeholders can find in the companies when they choose to opt out auditing.

Modern organizations (e.g., hospitals, banks, social networks, search engines) hold large volumes of personal information, and rely heavily on auditing for enforcement of privacy policies. These audit mechanisms combine automated methods with human input to detect and punish violators. Since human audit resources are limited, and often not sufficient to investigate all potential violations, current state-of-the -art audit tools provide heuristics to guide human effort. However, numerous reports of privacy breaches caused by malicious insiders bring to question the effectiveness of these audit mechanisms. Our thesis is that effective audit resource allocation and punishment levels can be efficiently computed by modeling the audit process as a game between a rational auditor and a rational or worst-case auditee. We present several results in support of the thesis. In the worst-case adversary setting, we design a game model taking into account organizational cost of auditing and loss from violations. We propose the notion of low regret as a desired audit property and provide a regret minimizing audit algorithm that outputs an optimal audit resource allocation strategy. The algorithm improves upon prior regret bounds in the partial information setting. In the rational adversary setting, we enable punishments by the auditor, and model the adversary's utility as a trade-off between the benefit from violations and loss due to punishment when detected. Our Stackelberg game model generalizes an existing deployed security game model with punishment parameters. It applies to natural auditing settings with multiple auditors where each auditor is restricted to audit a subset of the potential violations. We provide novel polynomial time algorithms to approximate the non-convex optimization problem used to compute the Stackelberg equilibrium. The algorithms output optimal audit resource allocation strategy and punishment levels. We also provide a method to reduce the optimization problem size, achieving up to 5x speedup for realistic instances of the audit problem, and for the related security game instances.
