As a result, it is questioned whether the regulatory model applied is the most suitable for promoting the goals of economic regulation, or if the most appropriate regulatory model would be different, being necessary to reform the regulatory structure. Thus, this work provides a critical view of the existing regulatory models, especially the unissetorial one, and upholds for a multissetorial, conceived as more appropriate to face the new entrepreneurial behaviors, such as horizontal specialization and internationalization, as well as to promote effective information management, preventing the regulator of the consequences stemming from asymmetric information. It is still unpredictable whether a shift of regulatory standards in the major world economies will minimize the effects of market failures. This paper analyzes the main aspects of this problem in order to promote greater discussion of the models and structure of regulatory agencies. / Diante das transformações advindas da onda de fusões empresariais das últimas décadas, ao processo mundial de liberalização e também alguns avanços tecnológicos decorrentes da fase atual da globalização, novos desafios se apresentam para a regulação econômica. Como consequência, é questionado se o modelo de regulação aplicado é o mais adequado para a promoção dos objetivos da regulação econômica, ou se o modelo regulatório mais apropriado seria outro, sendo necessária a reforma da estrutura regulatória. Nesse sentido, este trabalho estabelece uma visão crítica dos modelos regulatórios existentes, principalmente, o modelo unissetorial, e propugna por um multissetorial, concebido como mais apropriado frente aos novos comportamentos empresariais, como a especialização horizontal e a internacionalização, assim como, para a promoção da gestão informacional eficaz, prevenindo o ente regulador das consequências advindas das informações assimétricas. Ainda é imprevisível saber se uma mudança de atuação regulatória nas grandes economias do mundo minimizará os efeitos das falhas de mercado. Este trabalho analisa os principais aspectos dessa problemática de modo a promover maior discussão sobre os modelos de atuação e estruturação das agências reguladoras.

nÃo hà / Este trabalho se inicia analisando os aspectos teÃricos relacionados ao financiamento das empresas e os riscos atrelados a esta atividade de emprÃstimo realizada pelo sistema financeiro bancÃrio. Dada uma estrutura Ãtima de capital buscada pelas empresas, passa-se a analisar se este parÃmetro ou conjunto de parÃmetros à um bom indicativo para discriminar as empresas quanto ao seu risco de crÃdito analisado pelo mercado financeiro. Em relaÃÃo à gestÃo de risco, serà testado um modelo, tendo como variÃvel explicativa principal a variÃvel(ou conjunto de variÃveis) utilizada como parÃmetro de sinalizaÃÃo ao mercado de limite de risco, dentro dos conceitos de seleÃÃo adversa e modelos de sinalizaÃÃo num ambiente em que impera a informaÃÃo assimÃtrica. Assim, o uso de um sinalizador Ãtimo da estrutura de capital pelos bancos levaria a um equilÃbrio de Nash1 com informaÃÃo assimÃtrica no mercado de fundos emprestÃveis. No desenvolvimento do modelo estatÃstico utilizamos um modelo Logit em virtude da nÃo normalidade e as condiÃÃes de nÃo linearidade do modelo de probabilidade linear, entretanto, a anÃlise discriminante e Probit serÃo testados concomitantemente para efeitos comparativos entre os modelos. Outro ponto importante à a incorporaÃÃo de um modelo de decisÃo de crÃdito com o uso de programaÃÃo Linear Inteira. O uso deste modelo incorpora cenÃrios prospectivos com a taxa de juros, qualificando o ponto de corte(limites de aceitaÃÃo) para tomada de decisÃo. Ressaltamos aqui a importÃncia do uso da anÃlise fatorial no tratamento e configuraÃÃo das variÃveis explicativas, ferramenta nÃo observada para modelagem de risco nas diversas referencias deste trabalho. Diversos mÃtodos estatÃsticos univariados e multivariados, assim como critÃrios qualitativos sÃo usados na discriminaÃÃo e classificaÃÃo do risco, no entanto, o uso da AnÃlise Fatorial qualifica ainda mas as variÃveis independentes usadas, colocando-as em grupos de explicaÃÃo que captam melhor os efeitos dos diversos indicadores econÃmicofinanceiros. Neste trabalho foram revisados os principais modelos de insolvÃncia para avaliaÃÃo de risco de crÃdito no Brasil, concluindo-se com uma proposta de adoÃÃo de um modelo estatÃstico com o uso do modelo Logit e ProgramaÃÃo Linear Inteira, com o objetivo de medir o risco associado ao financiamento e emprÃstimo a clientes. / This work to research the theory about enterprises financial, financial struture, risk of the borrowe (enterprises) to repay the loan, credit of banks. In views of the optimal capital struture, credit analyses examines factors that may lead to default in the repayment of a loan. As for the risk management the general kinds of risks are described, particularly the credit risc and the credit concession models are evaluated. The risc models will have the financial demonstrations of interprises, here can be viewed as a signal, about the concept of asymmetric information. Thus, the signal to leave a nash equilibrium in this credit market. In the development of the statistic model, using the Logit Model because the problems of functional form of the linear probability model, the resÃduos is heteroscedastic and not have normal distribuition. The discriminant analyse, probit e logit will be test. Another important point in this work is the decision model. This model have predtion of interest to improve the decision with the cutoff. Referring to the factorial analyse in the statistic of the independentes variable, the use of factorial analyses is not observations in the reference. Having this purpose in mind a statistic model was developed, using logit regression with factorial analyse in variable and linear programming. This project aims at evaluating the used models and proposing the adoption of new models, for the allowance for dobtful accounts, with the objetive of mensuring the risk related to customers financing and loan activities.

The thesis explores how monetisation of corporate externalities, can be carried out in order to provide investors, policy makers and consumers with accurate pictures of the true costs and benefits of business operations from a resilience and ecosystem services perspective. By drawing conclusions from company cases, and previous research – methods, drivers and monetary values of impacts such as carbon dioxide, water usage, pollutants and land use are analysed. The findings reflect opportunities that open up with monetisation, in terms of tools for guidance and support in internal corporate decision making, by making the actual impacts visualised and understandable. Findings from company cases, show that monetisation of corporate effects has potential to contribute to visualising impacts – and add knowledge that may close information gaps internally as well as externally. It can guide and facilitate strategic choices at corporate level. It may also have a role in bridging information asymmetries in the picture of a firm’s operation, to consumers and investors. Monetising effects may facilitate identification of risks arising from ecosystem services dependencies, visualising the actual impacts by, assed costs in losses in ecosystems’ production (yields e.g.) caused by corporate harm.Providing relevant information to policy makers, on obstacles and where regulative incentives are needed, and investors and consumers with guidance, monetisation of impacts potentially can play a part in bridging market information gaps toward better incentive structures and possibly facilitating effective market transformation in favor of sustainable production and consumption patterns.

Cette thèse étudie le rôle des tierces parties dans les problématiques informationnelles autour de la responsabilité sociale et environnementale des entreprises (RSE). Les entreprises revendiquent de plus en plus le fait qu'elles adoptent des pratiques responsables. Cela peut être lié au fait qu'il existe des parties prenantes (e.g. consommateurs, investisseurs) qui sont prêtes à récompenser les comportements responsables. Cependant, la véracité des revendications des entreprises est souvent impossible ou au moins difficile à certifier, ce qui peut inciter les entreprises à manipuler leur communication. Cette dissertation a pour objectif d'analyser la façon dont de tierces parties peuvent tempérer cette asymétrie d'information. Des organisations comme des agences de notations, des organisations non-gouvernementales (ONGs) ou des organismes certificateurs, peuvent examiner les actions réelles des entreprises et transmettre cette information aux parties prenantes. Ces tierces parties ont un comportement informationnel hétérogène: certaines fournissent des informations plus particulièrement sur les entreprises qui se comportent de manière irresponsable, alors que d'autres se spécialisent dans la mise en lumière des entreprises responsables. Nous développons un modèle théorique simple qui explore l'offre de qualité dans des environnements informationnels amicaux, où la qualité est révélée plus souvent lorsqu'elle est haute que lorsqu'elle est basse, et dans des environnements hostiles, où c'est l'inverse. Nous appliquons ensuite ce modèle à deux types de tierces parties: les ONGs et les labels. Nous étudions le choix de production de bonnes ou mauvaises nouvelles afin de comprendre quand et pourquoi les ONGs choisissent d'être hostiles ou amicales. Ensuite, nous cherchons à évaluer quel est le niveau de sévérité des labels qui entraîne le plus d'investissement et le bien être social le plus important. / This thesis studies the role of third parties in tempering informational issues at stake with regard to corporate social responsibility (CSR). Firms growingly claim to be adopting responsible practices, and it may be so because some socially conscious stakeholders (e.g. consumers, investors) are ready to reward such behaviors. Nevertheless, truthfulness of firms' virtue claims is often impossible or at least difficult to ascertain, which creates an incentive for firms to manipulate their communication. This dissertation intends to analyse how third parties can temper this asymmetry of information. Organisms such as rating agencies, non-governmental organisations, labeling institutions, can investigate firms' real actions and convey this information to stakeholders. These third parties have heterogeneous informational behaviors: some of them mostly disclose information on firms that do not behave responsibly while others are specialized in revealing firms that are socially or environmentally responsible. We develop a simple theoretical model that explores the provision of quality by a firm under friendly informational environments, in which quality is more often disclosed when it is high than when it is low, and hostile environments, in which the converse holds. We apply this base model to two types of third party: NGOs and labels. We endogenize the production of good and bad news in order to understand when and why NGOs choose between being hostile or friendly. Then, we seek to assess what is the more efficient level of label's strictness to spur social welfare and investment in high quality.

This dissertation contains three essays on environmental economics and on credit market imperfections. The literature on carbon tax incidence generally finds that carbon taxes have a regressive impact on the distribution of income. The main reason for that finding stems from the fact that poor households spend a larger share of their total expenditure on energy products than the rich households do. This literature, however, has ignored the impact of carbon taxes on income stemming from changes in relative factor prices. Yet, changes in household welfare depend not only on variations in commodity prices, but also on changes in income. Chapter 1 provides a comprehensive analysis of the distributional impact of carbon taxes on inequality by considering both demand-side and supply-side channels. We use a multi-sector, multi-household general equilibrium model to analyze the distributional impact of carbon taxes on inequality. Using equivalent income as the household welfare metric, we apply the Shapley value and concentration index approaches to decomposing household inequality. Our simulation results suggest that carbon taxes exert a larger negative impact on the income of the rich than that of the poor, and are thereby progressive. On the other hand, when assessed from the use side alone (i.e., commodity prices alone), our results confirm previous findings, whereas carbon taxes are regressive. However, due to the stronger incidence of carbon taxes on inequality from the income side, our results suggest that the carbon tax tends to reduce inequality. These findings further suggest that the traditional approach of assessing the impact of carbon taxes on inequality through changes in commodity prices alone may be misleading. Chapter 2 investigates the economic impacts of creating an emissions bubble between Canada and the US in a context of subglobal participation in efforts to reduce pollution with market based-instruments. One of the advantages of an emissions bubble is that it can be beneficial to countries that differ in their production and consumption patterns. To address the competitiveness issue that arises from the free-rider problem in the area of climate-change mitigation, we consider the imposition of a border tax adjustment (BTA) - a commonly suggested solution in the literature. We develop a detailed multisector and multi-regional general equilibrium model to analyze the welfare, aggregate, sectoral and trade impacts of the formation of an emissions bubble between Canada and the US with and without BTA. Our simulation results suggest that, in the absence of BTA, the creation of the bubble would make both countries better off through a positive terms-of-trade effect, and more importantly, through a significant reduction in Canada’s marginal abatement cost. The benefits of these positive effects would spill over to the non-participating countries, leading them to increase their trade shares in non-emissions-intensive goods. Moreover, the simulation results also indicate that a unilateral implementation of a BTA by any one of the two countries is welfare deteriorating in the imposing country and welfare improving in the other. In contrast, a joint implementation of a BTA by the two countries would make Canada better off and the US worse off. Chapter 3 shows that learning by lending is a potential channel of understanding the business cycle fluctuation under an imperfect credit market. An endogenous link among the learning parameter, lending rates, and the size of investment makes it possible to generate an internal propagation even due to a temporary shock. The main finding of this chapter is the explanation of how ex post non-financial factors such as information losses by individual agents in a credit market may account for a persistence in real indicators such as capital stock and output.

This paper aims to find an optimal regulatory system for banking industry. In its first part, it analyzes main sources of banking crises throughout 20th and 21st century. In the second part, it proposes a regulatory system and its tools. Analysis is based on understanding of incentives of market participants, regulators and their interactions. Regulatory tools are assessed in terms of efficiency, i.e. examining their consequences for the economy. This paper is based on an idea that despite unquestionable flaws, market mechanism is the best tool to organize an economy and its industries.

La crise financière de 2009 a ravivé le débat entre les classiques et les keynésiens concernant le rôle de la finance dans le cycle d’affaire. Cette thèse étudie les conséquences macroéconomiques des imperfections du marché de crédit ainsi que quantifie leur impact sur le marché de travail. L’interaction entre chômage et frictions financière passe par l’hypothèse que les postes vacants sont financés par des fonds externes qui sont plus couteux qu’un financement interne, de par de l’impact de l’asymétrie d’information sur le marché du crédit. Il est alors montré, à l’aide de simulation d’un modèle DSGE calibré sur données US., qu’un choc financier négatif, i.e. un choc qui augmente la prime de risque sur le marché du crédit ou un choc qui détériore le bilan des entrepreneurs, réduit de manière significative les capacités d’emprunt, et, par conséquent, la création d’emplois diminue spécialement. En outre, un choc d'incertitude engendre une augmentation du taux de chômage et rend cette augmentation plus persistante en période de crise. Ce résultat est confirmé par une évidence empirique qui consistait à estimer un modèle VAR bayésien, où des variables de marché de travail réelles et financières. / The crisis of 2009 raised the question whether the financial conditions matter for the business cycles and the propagation of shocks originating in the financial sphere. I tried to drive a fine analysis of this issue using micro-founded general equilibrium models. The modelling choice was backed by empirical motivations. In three essays, i study the impact of monetary and financial shocks on growth and labour market dynamics. First, an expansionary monetary policy eases credit conditions, raises risk tolerance and the quality of borrowers and generates a liquidity effect. The potency of the monetary policy and the size of the credit channel depend considerably on the degree of financial frictions in the credit market. Second, a restrictive monetary policy shock, an positive credit shock and a positive uncertainty shocks have similar effects on the economy: they plunge the economy in a recession, with output, job creations, and hours worked decreasing, while unemployment and job destructions increase. In all cases the interest rate spread increase, therefore indicating that financial conditions deteriorate, which is interpreted as a sign that financial frictions play a critical role in the propagation of these shocks. Third, the interaction between financial and labour market frictions does exist. The interplay between the two indeed plays a role in propagating the shocks. A shock to net worth, a credit shock and an uncertainty shock play a non-trivial role for the dynamics on the labour market.

Bakgrund: Det råder inga tvivel om att revisorn har en explicit funktion till att stärka redovisningens trovärdighet. I det sociologiska perspektivet kan vi även förstå revisorns funktion som en producent av komfort medan vi i det ekonomiskt rationella perspektivet ser revision som ett medel för att minska informationsasymmetri. Covid-19 har orsakat omfattande utmaningar bland både företag och revisorer, vilket lyfter frågan om hur olika aspekter i revisionen har påverkats av att revidera företag med en uttalad riskfaktor. Riskfyllda företag i denna studie avser företag som har fått en utfärdad going concern-anmärkning. Sådana bedömningar har varit svåra för revisorn under covid-19, mot bakgrund av den ovisshet som präglat pandemin. Av den orsaken var det intressant att undersöka om revisionsprocessen har förändrats under covid-19 genom att analysera om det skett en förändring av revisionsarvodet och längden för revisionsprocessen. Syfte: Syftet med denna studie är att analysera förändringen av revisionsprocessen i samband med ökade risker i företag i en orolig samhällskontext. Metod: Studien är av kvantitativ karaktär då vi undersöker om det skett någon förändring av revisionsarvodet och längden på revisionsprocessen under covid-19. För att besvara syftet har relevanta variabler från årsredovisningar inhämtas för att göra tre olika statistiska undersökningar. Syftet var att undersöka frekvensen av skillnader och samband mellan variablerna. Slutsats: Resultatet visar att det skett en förändring av revisionsarvodet under covid-19. Resultatet påvisade även att det inte skett en förändring av revisionsprocessens längd under covid-19, även fast det förelåg en viss samvariation mellan revisionsarvode och längden på revisionsprocessen. Resultaten har visat tendenser till att kunna förklaras och förstås med hjälp av informationsasymmetri och skapande av komfort. / Background: There is no doubt that auditors have an explicit function to strengthen the credibility of a firms’ accounting and reporting. In the sociological perspective it can be understood that auditors function as a producer of comfort, meanwhile in the economical rational perspective, auditors are a function to reduce information asymmetry. Covid-19 has caused extensive challenges for firms and auditors, which enlightens the issue of auditing troubled firms. Troubled firms are in this study referenced to firms that have been assessed with a going-concern opinion. Going-concern opinions was difficult for the auditors to review during Covid-19, in the light of the uncertainties that bear the stamp of the pandemic. For this reason, it was interesting to study if the audit effort had changed during covid-19 by analyzing the possible changes in audit fees and audit reporting lag. Purpose: The purpose of this study is to analyze the changes of audit effort in association to increased risk in firms in context to a crisis. Method: The study identifies with a quantitative orientation as it studies the changes of audit fees and audit reporting lag during Covid-19. In order to achieve the purpose of the study, pertinent variables from the firms’ annual reports have been obtained to perform three statistical analyses. The purpose was to study the changes between two years and the correlation between the two variables. Conclusion: The results suggest an increase in audit fees during Covid-19. The results also indicate no change in the length of audit reporting lag during Covid-19, even though a covariance between audit fees and audit reporting lag was identified to a certain extent. The results have shown to be understood with support by information asymmetry and establishment of comfort.

Due Diligence is today an important part of the transaction process through sales of properties and is an important process for both sellers and buyers. The process intends to review an asset before a transaction to minimize the risks associated with the acquisition by detecting weaknesses and verify the asset's characteristics. The use of Due Diligence has become increasingly common over the past twenty years in the Swedish real estate market and there is no indication that this trend will decrease but rather increase. Although there is widespread use of the process both in acquisitions of corporations and properties, both in Sweden and in the rest of the world, it is costly for the purchasers and the concept is far from fully developed. This thesis aims to clarify what the real estate market thinks about the potential development of the process itself and the role of the actors. The main question is what opportunities exist to develop the concept of Due Diligence in real estate transactions. Given the high economic values that are found in real estate transactions, it is highly relevant to perform Due Diligence and therefore it is also important to review the opportunities to change this process if it is requested and feasible. The conclusions of the thesis shows that the actors in the real estate market believes that there are opportunities for development in the use of Due Diligence The possibilities includes seller's expanded role in information gathering , process delays , clearer and more transparent processes and a continuous development of the actors’ own processes. The thesis concludes with four proposals for a development process: An increased use of Due Diligence conducted by the seller as a complement to the buyer's own investigation, clearer procurement of consultants from the real estate owners, more accessible information earlier in the process from the sellers and consistent monitoring of the implemented processes. / Due Diligence utgör idag en viktig del av transaktionsprocessen vid överlåtelser av fastigheter och är en viktig process för både säljare och köpare. Processen avser att granska en tillgång inför en transaktion för att minimera riskerna med förvärvet genom att upptäcka brister och kontrollera tillgångens egenskaper. Användningen av Due Diligence har blivit allt vanligare de senaste tjugo åren på den svenska fastighetsmarknaden och inget tyder på att denna utveckling kommer att avta utan snarare tillta. Trots att det finns ett utbrett användande av processen både vid företags- och fastighetsförvärv, i både Sverige och i övriga världen, så är det kostsamt för beställarna och konceptet är långt ifrån färdigutvecklat. Detta examensarbete har som syfte att klargöra vad fastighetsmarknaden anser om potentiella utvecklingsmöjligheter av själva processen och de aktiva aktörernas roller. Den huvudsakliga frågeställningen är vilka möjligheter som föreligger att utveckla konceptet Due Diligence vid fastighetstransaktioner. Med tanke på de stora ekonomiska värdena som finns i fastighetstransaktioner är det högst relevant att utföra Due Diligence och därför är det också av stor vikt att se över möjligheter att förändra denna process om det efterfrågas och är genomförbart. Slutsatserna i examensarbetet visar på att aktörerna på fastighetsmarknaden anser att det finns utvecklingsmöjligheter i användandet av Due Diligence. Möjligheterna innebär bland annat säljarens utökade roll i informationsinsamlingen, processens tidsåtgång, tydligare och mer transparenta processer samt ett kontinuerligt utvecklingsarbete av aktörernas egna processer. Examensarbetet avslutas med fyra förslag avseende en utveckling av processen: Ett ökat användande av Due Diligence genomförd av säljaren som komplement till köparens egen granskning, tydligare upphandlingar av konsulter från fastighetsägarna, mer tillgänglig information tidigare i processen från säljarna och konsekventa uppföljningar av genomförda processer.
