Moral Hazard and Adverse Selection of Executive Compensation

Xian, Chunwei January 2010 (has links)
This dissertation investigates the structure of incentive contracts in which adverse selection problems are more severe. Specifically, I examine the moderating effect of R&D intensity on the relative weights placed on signals of ability and on performance measures in executive compensation. Furthermore, I also investigate the determinants on the compensation of university presidents. I find that that more weight is placed on signals of ability in R&D intensive firms and less weight is placed on performance measures. I find that R&D intensive firms pay more to executives with technical work experience and/or relevant educational degrees. Additionally, in the context of university presidents, the positive association between organizational complexity and executive compensation is driven by the role of managerial ability rather than by effort. This result also suggests that considering measures of organizational complexity (such as firm size and diversification) as control variables in empirical studies of executive compensation is the appropriate means by which to account for the impact of organizational complexity. / Business Administration/Accounting

Three essays on efficiency and incentives in teams and partnerships

Li, Jianpei 14 December 2007 (has links)
Die klassische oekonomische Theorie behauptet, dass Teams und Partnerschaften (Teilhaberschaften) vom Trittbrettfahrerproblem betroffen sind und dass kapitalistische Unternehmen besser in der Lage sind, Spieler zu gewuenschten Handlungen zu motivieren. Dies steht jedoch im Widerspruch zur Popularitaet von Teams und Partnerschaften als Organisationsform. Diese Dissertation zeigt, dass Teams und Partnerschaften keine nachteiligen Organisationsformen sind. Sie traegt verschiedenen Faktoren Rechnung, die großen Einfluss auf die Anreize zur Anstrengung haben, aber in der Literatur weitgehend vernachlaessigt wurden: 1) Turniereffekte in Teams; 2) soziale Praeferenzen; 3) Aufloesung einer Partnerschaft. Ob effiziente Anstrengung (Investition) erreicht werden kann, haengt entscheidend davon ab, welche Mechanismen angewandt werden um den Arbeitserfolg von Teams zu verteilen bzw. um eine Partnerschaft aufzuloesen. Wenn ein verrauschtes Signal der Rangfolge der Anstrengungen beobachtbar und kontrahierbar ist, dann kann effiziente Anstrengung als symmetrisches Gleichgewicht immer erreicht werden - durch Anwendung von Rangfolge-Turnieren zur Verteilung des Arbeitserfolges des Teams. Wenn die Spieler beschraenkt haftbar sind, dann muss die Rangfolge-Technologie hinreichend genau sein um effiziente Anstrengung zu generieren. Wenn die Spieler soziale Praeferenzen haben, kann effiziente Anstrengung erreicht werden durch Vereinbarung von zufaelliger Bestrafung. Wenn eine Partnerschaft von moeglicher Aufloesung bedroht ist, dann kann effiziente Investition und Aufloesung der Partnerschaft mit Hilfe eines Optionsvertrages erreicht werden. Am haeufigsten verwendet und empfohlen ist die "Texas shoot-out"-Aufloesungsregel ("Buy-sell-Regel"). Sie ist jedoch ineffizient, da sie entweder zu ueberinvestition in Verbindung mit effizienter Aufloesung oder zu Unterinvestition kombiniert mit exzessiver Aufloesung fuehrt. / Classic economic theory claims that teams and partnerships are inflicted with free-riding incentives and are inferior to capitalist firms in eliciting proper actions from players. This contradicts the popularity of teams and partnerships as organization forms. By accounting for several factors that may significantly affect effort provision (investment) but have been generally neglected in the literature: 1) tournament effect within teams; 2) other-regarding preferences; 3) possible dissolution of a partnership, this dissertation shows that teams and partnerships are not handicapped organization forms. Whether efficient efforts provision (investment) is achieved or not depends critically on the mechanisms employed in the allocation of team output and dissolution of a partnership. If some noisy ranking of efforts is observable and contractible, efficient provision of efforts can always be achieved in symmetric equilibrium by using rank-order tournaments to allocate the team output. If the players are subjected to limited liability, achievement of efficiency requires sufficient accuracy of the ranking technology. If the players show other-regarding preferences, efficient provision of efforts can be achieved through a randomly punishing contract. If the partnership faces possible dissolution, efficient investment and dissolution can be achieved through an option contract. However, the most widely used and recommended dissolution rule "buy-sell provision" fails to achieve efficiency as it leads to either excessive investment combined with efficient dissolution or underinvestment combined with excessive dissolution.

Sickness absence in Sweden : A study of early retirement and sickness absence

Najafi, Maja, Wollbratt, Marcus January 2008 (has links)
The purpose of this thesis has been to analyse seven major factors that tend to influence the rate of early retirement in Sweden. The scope of data was gathered for every municipality in Sweden. Economic theories of labour supply, Moral Hazard, Adverse Selection and the Insurance Model were used to analyse the empirical results. In the analysis, earlier studies of the rate of sickness absence were important and used as a framework in choosing the explanatory variables for the econometric model. The analysed variables were; average income, average sickness days, educational level, foreign born, public sector employment, unemployment and the share of women in the population. As a consequence of the rift that occurred in 2003, when the average sickness days decreased and disbursed early retirements simultaneously increased, the relationship between these two variables was given special attention. The empirical findings confirmed our conjectures and were consistent with earlier research. Average income and the level of education were negatively related to the rate of early retirement. Moreover foreign born, average sickness days and unemployment showed a positive relation to early retirement. The relationship between average sickness days and early retirement had statistically changed and decreased between the years. A possibility is that other factors, such as changed social norms and increased stress in society (which are difficult to measure in a statistical and economical sense) might have become more relevant in explaining the rate of early retirement. / Syftet med denna uppsats har varit att analysera sju viktiga faktorer som tenderar att påverka graden av förtidspensionering i Sverige. Data omfånget insamlades för alla kommuner i Sverige. Ekonomiska teorier om arbetsutbud, Moral Hazard, Adverse Selection och Insurance Model användes för att analysera de empiriska resultaten. I analysen var tidigare studier utav graden av sjukfrånvaro viktig och användes som ramverk i valet av de förklarande variablerna till den ekonometriska modellen. De analyserade variablerna var; medelinkomst, genom-snittliga sjukdagar, utbildningsnivå, utlandsfödda, offentligt anställda, arbetslöshet och andelen kvinnor i befolkningen. Som en konsekvens utav den klyfta som uppstod 2003, när de genomsnittliga sjukdagarna minskade och utbetalda förtidspensioner samtidigt ökade, gavs sambandet mellan dessa två variabler speciell uppmärksamhet. De empiriska iakttagelserna bekräftade våra förväntningar och stämde överens med tidigare forskning. Medelinkomst och utbildningsnivå var negativt relaterade till graden av förtidspensionering. Dessutom var utlandsfödd, genomsnittliga sjukdagar och arbetslöshet positivt relaterade till förtidspensionering. Relationen mellan de genomsnittliga sjukdagarna och graden av förtidspensionering hade statistiskt sätt ändrats genom att ha minskat mellan åren. En tänkbar förklaring till detta skulle kunna vara att andra faktorer, såsom skiftande sociala normer och en ökande stress i samhället (vilka är svåra att mäta statistiskt och ekonomiskt) kan ha blivit mer relevanta i att förklara graden av förtidspensionering.

När företaget är borta - dansar agenterna på bordet? : En studie om hur svenska små- och medelstora företag kan kontrollera sin agent på den internationella marknaden.

Luong, Melinda, Rådmark, Frida, Sjögren, Alexandra January 2013 (has links)
Globalisering har möjliggjort för svenska företag att expandera utomlands och etablera sig påinternationella marknader. Det största hindret för små- och medelstora företag (SMFs) i ainternationaliseringsprocess är avsaknad av finansiella medel och kunskap om den nyamarknaden. På grund av detta är användandet av en utlandsbaserad agent ett bra alternativ. Enagent har en god lokal marknadskunskap och representerar en etableringsform som är mindrekostsam i jämförelse med etableringen av ett dotterbolag. Med hänsyn till detta äranvändandet av en agent ett vanligt tillvägagångssätt bland internationaliserande SMFs.Samtidigt drivs företaget och dess agent av olika mål på grund av skillnader i egenintresse.Trots att en agent är anlitad i syfte att arbeta i enighet med företagets ambitioner, kan denneha ett egenintresse som kolliderar med företaget. Det är därför nödvändigt för företag attskydda det egna intresset genom implementering av olika kontrollsystem. I denna studie harvi använt oss av principal- agentteorin i syfte att förklara förhållandet mellan svenska SMFsoch dess agenter. Utöver detta undersöker vi även hur svenska SMFs kan kontrollera sinautlandsagenter. För att undersöka detta har vi formulerat följande forskningsfrågor: “Hur kanprincipal-agenteorin tillämpas i syfte att beskriva uppdragsrelationen mellan svenska SMFoch dess agent på den internationella marknaden?” samt ”Hur kan svenska SMFs styra attdess agent på den internationella marknaden arbetar enligt företagets önskemål?”. I syfte attbesvara dessa forskningsfrågor har det insamlats och bearbetats teoretiskt material, vilketutgjort underlag för den semistrukturerade intervjuguide som besvarats av studiensintervjupersoner. Detta har resulterat i en analys följt av slutsats där forskningsfrågornabesvaras. Studien avslutas med rekommendationer till framtida forskning. / Globalization has enabled firms to expand abroad and enter international markets. The mainobstacle for small and medium-sized firms in their internationalization-process is the lack offinancial resources and local market knowledge. Therefore, the use of an offshore agent is agood option. An agent holds good local market knowledge and represents an establishmentform that is less costly, compared to the start-up of a subsidiary. Hence, the use of an agent isa common approach amongst internationalized small and medium-sized firms (SME’s).Simultaneously, a firm and its agent are driven by different ambitions due to divergence intheir self-interests. Although an agent is hired to work in unity with the firm’s ambitions, itmay hold a self-interest that collides with the firm’s objectives. Therefore, it is vital for firmsto protect their own interests by implementing different mechanisms that can control theagent. In this study, the principal-agent theory has been applied in order to explain therelationship between Swedish SME’s and their agents. Additionally, it has been investigatedhow Swedish SME’s are able to control their offshore agents on the international market. Toexamine this, the following two research questions have been formulated: “How can theprincipal-agent theory be applied to describe the relation between Swedish SME’s and theiragent on the international market?” and “How can Swedish SME’s control that their agent onthe international market are working in unity with the firm’s requests?” In order to answerthese two questions, theoretical material has been collected and processed in order toformulate the basis of the semi-structured interview guide that has been answered by therespondents. This has resulted in an analysis followed by a conclusion where the researchquestions are answered.

Försäkringsbolags premiesättning : Vilka är bedömningsfaktorerna vid riskbedömning samt hur påverkar principal-agentteorin försäkringsbolagens beslutsfattande

Nilsson, Victor, Sofie, Månsson January 2018 (has links)
För försäkringsbolag är beslutsfattande en viktig process där privatpersoners situationer ska bedömas. Vilka bedömningsfaktorer som försäkringsbolag tar hänsyn till vid premiesättning har därför diskuterats. Likaså vilka svårigheter försäkringsbolag upplever inför och under beslutsfattandeprocessen av en försäkringspremie. Tidigare studier visar att beslutsfattandeprocessen innehåller element från ett bolags riskhantering till en försäkringstagares beteende och livssituation. I vår studie har vi valt att fokusera på motorförsäkring, sjuk- och olycksfallsförsäkring samt livförsäkring där premien kan variera utifrån försäkringstagarens beteende. Tidigare studier belyser också principal-agentteorin utifrån moral hazard och adverse selection som försäkringsbolags främsta dilemman. Vidare har vi i vår studie valt att undersöka genom intervju hur de nämnda dilemman påverkar försäkringsbolags beslutsfattande. Intervjuerna genomfördes med en kvalitativ metod. I vår slutsats konstateras att osäkerhet präglar försäkringsbolags beslutsfattande vilket påverkas av både moral hazard och adverse selection. Försäkringsbolag vill minska denna osäkerhet och använder sig därför av en tydlig riskhanteringspolicy. Likaledes läggs förhoppningar på att digitaliseringen ska underlätta visst beslutsfattande. / For insurance companies decision making is an important process where the situation for private persons are assessed. Which assessment criterias that are used for premium setting by insurance companies have therefore been discussed. Also what difficulties insurance companies experience before and during the decision making process of an insurance premium. Previous research shows that the decision making process contains elements from a company's risk management to a policyholder's behaviour and life situation. In our research we have chosen to focus on motor insurance, health insurance and life insurance where the premium can vary due to a policyholder’s behaviour. Previous research also estimate that principal-agent problem whit moral hazard and adverse selection constitutes insurance companies’ main dilemma. Furthermore, in our research we have chosen to look into, with interview, how the mentioned difficulties affect the decision making in insurance companies. The interviews were conducted with a qualitative method. In our conclusion is it noted that insecurity is characterized by insurance companies’ decision making which is affected by both moral hazard and adverse selection. Insurance companies want to decrease this insecurity and therefore uses a clear enterprise risk management. Likewise, hopes are being made that the digitization will facilitate certain decision making.

Effects of sponsorship in dental plans / Efeitos do patrocÃnio em planos odontolÃgicos

Felipe Pinho Carneiro 14 February 2012 (has links)
nÃo hà / The objective of this study is to identify and characterize the existence of moral hazard in the dental plans market when there is some kind of sponsorship in cash counter installments. This paper compares the behavior between plans with total sponsorship, with partial sponsorship and without sponsorship. Count Models were used to measure the over use of dental services. Empirical data from a exclusively dental plan, characterized by ANS as Odontologic Group, were collected, processed, described and analyzed to test the hypotheses raised about the moral hazard reduction when there is any kind of sponsorship. The results revealed strong evidence of regionalism in demand for appointments, showing localities where the sponsorship effect decreases the demand for appointments and other locations where the same effect increases this same demand. / O objetivo deste estudo à identificar e caracterizar a existÃncia do risco moral no mercado de planos odontolÃgicos quando da existÃncia de algum tipo de patrocÃnio nas contraprestaÃÃes pecuniÃrias. Este trabalho compara o comportamento de utilizaÃÃo entre planos com patrocÃnio total, com patrocÃnio parcial e sem patrocÃnio. Fez-se uso dos modelos de contagem visando mensurar a sobreutilizaÃÃo dos serviÃos odontolÃgicos. Dados empÃricos oriundos de uma operadora exclusivamente odontolÃgica, caracterizada pela ANS como odontologia de grupo, foram coletados, tratados, descritos e analisados buscando testar as hipÃteses levantadas sobre a reduÃÃo do risco moral quando hà algum tipo de patrocÃnio. Os resultados revelaram fortes indÃcios de regionalismo na demanda por consultas, apresentando localidades onde o efeito de patrocÃnio diminui a demanda por consultas e outras localidades onde o mesmo efeito aumenta esta demanda.

Leasing Risks and Commercial Real Estate : A Study on the Relationship Between Risk Premium and Leasing Risks / Hyresgästrisker och kommersiella fastigheter : En studie på sambandet mellan riskpremieoch hyresgästrisker

Bohman, Peter, Karlsson, Erik January 2019 (has links)
Purpose: The purpose of this thesis paper is to evaluate what the current market practice of real estatevaluation and investment decisions is when it comes to different leasing risks and the risk premium.With regard to some of the ongoing trends within real estate, it is believed that investor preferencesaffect the market practice and the underlying theories of valuation does not fully comply to the currentmarket practice. Method: The implementation of the method is stage wise. At first already existing research andliterature was evaluated and triangulated to find relevant knowledge as basis for the theoreticalframework. Afterwards an analysis was performed to answer whether there is a research gap or not.By analyzing the literature, a research gap as well as potential problems related to leasing risks wasfound. The second phase consisted of a qualitative method where experts in the field were interviewedregarding leasing risk to evaluate whether the problem exist in practice or only in literature.Experts on the topic also helped to develop the questions consequently delivered to the interviewees.The mentioned strategy was done with guidance of our tutor Han-Suck Song at KTH and DanielHolmkvist at CBRE. Interviews: Nine interviews were conducted where experts in the business (consultants and propertyfirms) participated to deliver different perspectives on the research question. All interviews were madein Stockholm and held in Swedish and afterwards translated to English. Results: The results consist of the answers from the interview-part, where the relevant findings weresummarized and pin-pointed with regard to the respective field of business and property segment.The general themes that arose throughout the methods are presented, as well as the extremes in termsof opinions and answers. It was found that there is a clear relationship between the leasing risk and therisk premium for commercial real estate. The relationship depends on several factors such asgeographical location, the different submarkets and finally the segment. A municipal- or corporate bondcannot be fully comparable to a leasing contract but for a 20 year or longer contract where the tenant ispublicly financed, the contract can become an interesting investment alternative due to the currentinterest rate cycle. Finally the leasing contract needs to be more effortless to liquidate in order to becomparable to the bond situation. Scientific relevance: The recent transaction activity on the Swedish real estate market has been ratherdefensive for multiple segments the last twelve months with an exception of community properties.A common understanding is that such objects feature “stable tenants” and are viewed as a safeinvestment by the market. This investment practice raises the awareness of what a stable tenant is, andhow the consultants and property owners’ reason during investments and appraising decisions.This research paper illustrates that a common perception on the subject is that the risk exposurecompletely depends on the specific segments, location or contract length etc. The academic researchexplains the theory behind how to derive the discount rate for an investment decision, however thisstudy has during the literature review proven that several important concepts are left out in the theorypartand thus does not fully cover phenomena’s that investors and appraisers are exposed to duringmarket practice. The most critical part is how to relate leasing risk to the risk premium on the Swedishmarket. Since this study focuses on specifically the Swedish market it is crucial to relate to suitableliterature review for further discussions. On foreign markets, more rigid literature on the subject wasfound. / Syfte: Syftet med detta examensarbete är att undersöka vad den aktuella marknadspraxisen inomfastighetsvärdering samt investeringsbeslut är gällande olika nivåer av hyresgästrisker och riskpremie. Metod: Genomförandet av undersökningen har gjorts i två steg. I ett första steg har tidigare forskninginom ämnet analyserats för att finna relevant teori samt identifiera eventuella forskningsgap. Efteranalysen konstaterades ett uppenbart informationsgap inom litteraturen relaterat till hyresgästrisker.Den andra fasen bestod av en kvalitativ metod där experter inom området har intervjuats gällandehyresgästrisker, för att utvärdera om problemet finns i praktiken eller endast i teorin. För att konstruerafrågorna fick vi assistans av experter inom ämnet via våra handledare Han-Suck Song, KTH och DanielHolmkvist, CBRE. Intervjuer: Nio intervjuer genomfördes med experter inom ämnet där både konsulter ochfastighetsägare deltog för att presentera olika synvinklar på problemet. Samtliga intervjuer ärgenomförda i Stockholm och på svenska. Intervjuavsnitten har översatts till engelska i efterhand. Resultat: Resultatavsnittet består av de svar som har erhållits från intervjuerna, där relevantaresonemang har summerats och noggrant strukturerats för att koppla marknadsområden till korrektfastighetssegment. Återkommande teman och ämnen har presenterats i resultatavsnittet, så väl somavvikande uppfattningar. Resultatet visar att det finns ett tydligt samband mellan riskpremium ochhyresgästrisker gällande kommersiella fastigheter. Sambandet beror på ett flertal faktorer där läge ochfastighetssegment har störst inverkan på riskpremien. Gällande obligationsmarknaden går det inte attlikställa ett hyresavtal med en obligation under något förhållande. Däremot om avtalet avser enkontraktslängd på 20 år eller längre och en offentligt finansierad hyresgäst så kan kassaflödet bli ettintressant investeringsalternativ till befintliga obligationer på marknaden. Detta beror till stor del pånuvarande ränteläge. Slutligen måste ett hyresavtal bli lättare att omsätta för att kunna jämföras meden alternativ obligation. Vetenskaplig relevans: Transaktionsaktiviteten på den svenska fastighetsmarknaden har varit relativtdefensiv för flertalet segment med undantag för samhällsfastigheter de senaste tolv månaderna. Dengenerella uppfattningen är att samhällsfastigheter avser ”stabila hyresgäster” och därmed ses som enmindre riskfylld investering. Detta medför frågeställningen, vad avses för att klassificera en hyresgästsom stabil, och hur resonerar konsulter samt fastighetsägare vid investerings- och värderingsbeslut?Efter att ha genomfört undersökningen går det att konstatera att en allmän uppfattning bland experterinom området är att hyresgästrisken till största del beror på vilket segment, lokalisering ellerkontraktslängd som avses. Den akademiska litteraturen förklarar hur diskonteringsräntan härleds förinvesteringsbeslut, men denna undersökning visar att den tillgängliga litteraturen antingen utelämnarflera viktiga koncept eller inte tillräckligt belyser fenomen som investerare och värderare möter i sittpraktiska arbete. Det grundläggande avsnittet som svensk litteratur till viss del utelämnar är sambandetmellan risk premium och hyresgästrisk på specifikt den svenska marknaden. Det finns utländsk litteratursom belyser denna typ av frågeställningar, men just för den svenska marknaden är litteraturen till vissdel ej tillräcklig och därmed har ett potentiellt forskningsgap inom området identifieras.

Asymmetric information in the regulation of the access to markets

Ghislandi, Simone, Kuhn, Michael 02 1900 (has links) (PDF)
It is frequently argued that the high costs of clinical trials prior to the admission of new pharmaceuticals are stifling innovation. At the same time, regulation of the access to markets is often justified on the basis of consumers` inability to detect the true quality of a product. We examine these arguments from an information economic perspective by setting a framework where the incentives to invest in R&D are influenced by the information structure prevailing when the product is launched in the market at a later stage. In this setting, by changing the information structure, regulation (or the lack of) can thus indirectly affect R&D efforts. More formally, we construct a moral hazard - cum - adverse selection model in which a pharmaceutical firm exerts an unobservable effort towards developing an innovative (high quality) drug (moral hazard) and then announces the (unobservable) quality outcome to an uninformed regulator and/or consumers (adverse selection). We compare the outcomes in regard to innovation effort and expected welfare under two regimes: (i) regulation, where products undergo a clinical trial designed to ascertain product quality at the point of market access; and (ii) laissez-faire with free entry, where the revelation of quality is left to the market process. Results show that whether or not innovation is greater in the presence of entry regulation crucially depends on the efficacy of the trial in identifying (poor) quality, on the probability that unknown qualities are revealed in the market process, and on the preference and cost structure. The welfare ranking of the two regimes depends on the differential effort incentive and on the net welfare gain from implementing full information instantaneously. For example, in settings of vertical monopoly, vertical differentiation and horizontal differentiation with no variable cost of quality, entry regulation tends to be the preferred regime if the effort incentive under pooling is relatively low and profits do not count too much towards welfare. A complementary numerical Analysis shows how the outcomes vary with the market and cost structure. (authors' abstract) / Series: Department of Economics Working Paper Series

An evaluation of the performance of microfinance institutions in Ghana : an investigation into the factors that impact on sustainability and success of microfinance institutions in Sub-Saharan Africa

Aveh, Felix Kwame January 2011 (has links)
The thesis examines factors that influence sustainability and success of microfinance institutions in Ghana. The topic is important, particularly in poverty stricken Africa, where microfinance institutions play a significant role in supporting governments' initiatives to reduce/alleviate poverty. The developed model is tested using data collected from 14 face-to-face interviews and 114 questionnaires. The data is analysed using different techniques- descriptive statistics, cross-tabulations and regression analysis. The research design and scale of the study are appropriate to both the problem addressed and doctoral level research. A number of factors in the model developed were found to be influencing the sustainability and success of microfinance institutions. A model was proposed that seeks to offer an explanation of sustainability and success of Microfinance Institutions in Ghana. The proposed model identified five categories being: institutional characteristics, agency costs, business strategy, environment/governance and success. Single factor analysis established positive relationships between sustainability and all the five factors but placed more emphasis on three out of the five factors namely; success, business strategy and environment/ governance. Multiple factor analysis established no significant differences in the sustainability with respect to the type of MFI, ownership and source of funding. Multiple Regression which allows for the testing of theories or models established a significant relationship between the Operational Self Sufficiency (OSS) and the predictors, especially the drop-out rate of clients and average loans. The Subsidy Dependence Index (SDI) was calculated for the various types of MFIs and the result was a high dependency ratio especially among the FNGOs. Though the dependency is on the decline, it is very slow indicating that most MFIs will depend on subsidies for a very long time to come. Finally it was observed that the relatively high interest rates charged by most of the MFIs tended to defeat the purpose for which the microfinance movement came about. Not only did the study confirm the research model, but it also revealed that most owners did not exhibit a deep sense of involvement and used general knowledge to practice in Ghana. The study concluded that success factors, business strategy, and environment/governance were the most critical of the sustainability factors in Ghana. It is therefore important that managers develop institutional capacities especially in managing the agency problem effectively if they have to be sustainable and successful.
