This thesis extends the standard shirking model of efficiency wages to a continuum of effort levels. The generalisation completely overturns previous intuitions. In particular, the characteristic feature of the earlier theory that monitoring and pay are substitute instruments for motivating workers, no longer exists. This is remarkable, since such a negative correlation has been used as the primary empirical test for the existence of efficiency wages. With a continuum of effort levels, the efficiency wage model can also more conveniently be compared with conventional linear incentive wages. The most frequently recurring objection against the efficiency wage model is that unemployed workers should offer to pay entrance fees. This criticism is responded to in a model with finitely many periods. It is shown that the per period worker rents associated with efficiency wages strongly diminishes with the number of periods. It is further argued that both bonds and entrance fees are inferior means of extracting the remaining worker rents compared to investments in firm specific human capital. Finally, the above refinements of the efficiency wage theory are translated to fit in the arena of environmental economics and government policy. The corresponding results establish a rationale for a government to subsidise polluting firms and explain why a command and control policy is preferable to market-based incentive schemes. / Diss.

Bakgrund: Revisionens syfte är att genom en oberoende granskning minska den informationsasymmetri som finns mellan ägare och företagsledning. Nya regler angående bland annat innehållet i revisionsberättelsen trädde ikraft 2016 med syfte att bland annat minska det informationsgap som finns på marknaden. Vår studie har sin utgångspunkt i om mängden informationsasymmetri påverkar revisionskostnaden och om den nya lagändringens syfte uppnåtts.   Syfte: Studiens syfte är att förklara sambandet mellan informationsasymmetri och revisionskostnad i svenska börsbolag. En jämförelse görs även mellan år 2015 och 2016 för att se om de nya kraven på revisionsberättelsen har någon inverkan på informationsasymmetri och revisionskostnad samt sambandet dem emellan.   Metod: Studien har en deduktiv forskningsansats där agentteorin varit utgångspunkt för att härleda hypoteser. Urvalet i den kvantitativa forskningsmetoden har varit svenska bolag listade på small-, mid- och largecap åren 2015 och 2016.   Resultat: Studiens resultat har visat på att det det finns ett negativt samband mellan informationsasymmetri och revisionskostnad. Det kan också konstateras att den nya revisionsberättelsen inte bidragit med en minskad informationsasymmetri och inte heller en ökad revisionskostnad. / Background: The aim of audit is to independently review and reduce the information asymmetry that exists between the owners and management of the firm. A new law about the content of the audit report was implemented 2016 with the purpose of reducing the information gap on the market. Our study is based on whether or not the amount of information asymmetry affects the audit fee and if the purpose of the new law has been reached. Purpose: The purpose of the study is to explain the relationship between information asymmetry and audit fee in Swedish companies listed on the stock exchange market. A comparison between the years of 2015 and 2016 is made to investigate if the new requirements on the audit report have any affection on the information asymmetry, audit fee and the relationship in between. Method: The study has a deductive research approach with the base of agency theory to deduce hypotheses. The sample in the quantitative research methodology consists of Swedish companies listed on small-, mid- and largecap 2015 and 2016. Conclusions: The result of the study concludes that there is a negative relationship between information asymmetry and audit fees. It can also be concluded that the new audit report does not contribute to a reduction of information asymmetry nor an increased audit fee.

Magister Educationis - MEd / Since the onset of democracy in 1994, education in South Africa has undergone many developments and changes due to curriculum innovations and interventions. For more than two decades, the government has been seeking to eliminate the divisions of the past by establishing a society based on democratic values, social justice and the observance of fundamental human rights as described in Act 108 of 1996 in the Constitution. The curriculum changes in South Africa after 1994 had a huge impact on the education system as a whole, and classroom teaching shifted from being largely teacher- centered to being predominantly learner-centered. Hence, the newly revised Curriculum and Assessment Policy Statement (CAPS) was introduced (DBE, 2011) to provide all teachers with the same outline of what should be taught, when and how. The government's efforts at improving teaching and learning as well as maintaining a high standard of education are commendable, however, findings through this research demonstrate that CAPS disregards the massive differences in terms of contexts within which schools operate and the general lack of resources faced by certain schools. The main aim of this research was to explore the nature of the capability sets of teachers with respect to the implementation of the CAPS curriculum in a no fee school community in the Western Cape. The research was conducted within the framework of a qualitative research approach with a case study design. Classroom observation, focus group interviews and document analysis were utilized as data collection methods. The capability approach of Amartya Sen was applied to unveil the nature of teachers' capability sets in a no fee school in the Western Cape. This study has established that there are several factors inside and outside the school, which influence the implementation of CAPS during the teaching and assessment processes. Therefore, recommendations are made that the policymakers should take into account the context and socio economic background of the school and learners before changing the curriculum.

O uso de praguicidas vem sendo a principal forma de combater os ectoparasitas dos viveiros de peixes, sendo que os mais utilizados na bacia do rio Mogi-Guaçu são o diflubenzuron (DFB), e os organofosforados paration metílico (PM) e triclorfon (TCF), cujo principal subproduto é o diclorvós (DDVP). O uso indiscriminado destas substâncias nos cultivos de peixes pode ocasionar danos aos ecossistemas aquáticos que recebem os efluentes dos tanques comprometendo a qualidade ambiental, além de representar risco aos consumidores destes pescados. Conhecer o padrão de acumulação destes praguicidas, bem como o efeito em espécies não-alvo são fundamentais para a correta gestão desta atividade. Foram analisadas quanto à presença de DFB (CLAE-DAD), PM e DDVP (CG-NPD), amostras de água, sedimentos e peixes (Oreochromis niloticus) coletadas em três pesqueiros do município de Socorro, SP (junho de 2005) e em 4 tanques experimentais (10.000 L de água, 10 cm de sedimento arenoso, localizados no CRHEA - USP, Itirapina, SP) os quais foram utilizados num experimento de simulação de tratamento contra ectoparasitas de peixes (junho a agosto de 2005). Neste caso, antes e após uma única aplicação das formulações Dimilin (1,0 g/\'M POT.3\' DFB), Folisuper (0,25 g/\'M POT.3\' PM) e Neguvon (0,25 g/\'M POT.3\' TCF), amostras de água sedimentos, peixes e comunidades fitoplanctônica, zooplanctônica e de macroinvertebrados bentônicos foram coletadas nos tempos zero, 5 horas, 1, 2, 5 e 7 dias após as aplicações. Não foram detectados resíduos dos praguicidas em nenhuma das amostras coletadas nos três pesqueiros do município de Socorro, SP. Foram detectados resíduos nos compartimentos e efeitos nos grupos de organismos analisados nos tanques experimentais. O DFB é persistente nos compartimentos água e sedimentos, assim como o PM o qual possui menor persistência. O DDVP não é persistente nestes compartimentos. Houve acúmulo de DFB e PM nos filés de peixes submetidos ao tratamento com Dimilin e Folisuper, respectivamente, em todos os tempos amostrados. Estes valores excederam os limites máximos recomendados para alimentos segundo o Codex Alimentarius. As aplicações dos praguicidas causaram efeitos na composição e densidade das comunidades biológicas os quais variaram em função do produto aplicado e do tempo de exposição. De maneira geral, os macroinvertebrados bentônicos foram mais sensíveis aos organofosforados, enquanto que o zooplâncton foi mais sensível ao DFB. Os cladóceros mostraram alto grau de sensibilidade para todos os praguicidas aplicados. Com relação à comunidade fitoplanctônica, aparentemente os praguicidas causaram efeitos indiretos na composição e densidade deste grupo. / The use of pesticides has been the foremost course of action to combat the ectoparasites of farmed fee fishes, in which diflubenzuron (DFB) and the organophosphates methyl parathion (PM) and trichlorfon (TRC) (witch the main sub product is dichlorvos - DDVP) are the most widely used in the Mogi-Guaçu river catchments. The indiscriminate use of such compounds on aquaculture can cause damage to the aquatic ecosystems that receive the pond\'s effluents, hence endangering environmental quality and consumer\'s health. The knowledge of understanding the environmental fate, accumulation rate, as well as their effect upon non-target species, is particularly important for the correct aquaculture management. Samples of water, sediments and fishes (Oreochromis niloticus) from three fee fishing enterprises from Socorro, SP, Brazil (June, 2005), were analyzed to verify residues of DFB (HPLC-DAD), PM and DDVP (GC-NPD). In addition, four experimental ponds (10.000 L, 10 cm of sediment, localized on CRHEA - USP, Itirapina, SP, Brazil) were used to simulate a treatment against fish ectoparasites (June to August, 2005). In this case, before and after a single application of Dimilin (1,0 g/\'M POT.3\' DFB), Folisuper (0,25 g/\'M POT.3\' PM) and Neguvon (0,25 g/\'M POT.3\' TCF), samples of water, sediments, fishes, phytoplankton, zooplankton and benthonic macro invertebrates were collected on zero, 5 hours, 1, 2, 5 and 7 days after contamination. No pesticides residues in the samples of the three fee fishing enterprises from Socorro were detected. Pesticides residues in the compartments and effects in all of the organism groups analyzed were detected on the experimental ponds. The DFB is persistent in water and sediments, as well as the PM, which was comparatively less persistent. However, DDVP is not persistent on those compartments. There was DFB and PM accumulation on fish filets subjected to treatment with Dimilin and Folisuper, respectively, which were detected in all sampled times. These values exceed maximal level limits proposed by the Codex Alimentarius. The pesticides applications caused effects on the biological community composition and density, which varied due to the formulation applied and time exposition. Overall, the benthonic macro invertebrates were more sensitive to organophosphorates, while zooplankton were more sensitive to DFB. The cladocerans indicated high degree of sensitivity to all pesticides applied. With respect to phytoplankton, apparently, pesticides caused only indirect effects upon the composition and density of this group.

Performance fees charged upon investment funds may be regarded as buying a financial call option. In theory, the value of a call option is directly proportional (ceteris paribus) to the volatility of the underlying asset (i.e. the fund quota, in this case). As it is, there is a clear incentive to increase volatility of the quotas of the funds that charge a performance fee. However, on contrary to expectations, the results indicate that those funds that charge a performance fee have presented not only a smaller risk, but also greater efficiency, measured by the relation risk / return. / Este estudo analisa o efeito da cobrança da taxa de performance sobre os fundos de ações na indústria brasileira de fundos de investimento. As taxas de performance cobradas dos fundos de investimento podem ser equiparadas a uma opção financeira de compra. Em tese, o valor da opção de compra é diretamente proporcional (ceteris paribus) à volatilidade do ativo subjacente (neste caso a cota do fundo). Sendo assim, há um claro incentivo ao aumento da volatilidade das cotas dos fundos de ações que cobram taxa de performance. Entretanto, contrariando as expectativas, os resultados indicaram que os fundos de ações que cobraram taxa de performance apresentaram, não somente, risco inferior, como também, maior eficiência, aferida pela relação risco / retorno.
