Samhället har under de senaste decennierna börjat ställa mer krav på att företag ska implementera hållbarhetsarbete i sin dagliga verksamhet. Det finns dock företag som väljer att bortse från dessa förväntningar då de anser att hållbarhetsarbete har en negativ inverkan på lönsamheten i form av ökade kostnader, till exempel genom omstruktureringar och utbildningar. De företag som inte har valt att arbeta hållbart är de företag som inte har en långsiktig syn på hållbarhetsarbete och inte heller kunskap om de fördelar som det kan leda till, både för företaget i sig, miljön och samhället i stort. En undersökning har visat att flera börsnoterade bolag i Sverige fortfarande har mycket att arbeta med inom hållbarhetsområdet. Däremot ökar medvetenheten kring att företag kan medverka till en mer hållbar utveckling. Den forskningsfråga som då blir aktuell är hur börsnoterade bolag i Sverige förenar lönsamhet och hållbarhet med fokus på miljöansvar. Syftet med studien är att försöka identifiera de faktorer som bidrar till en hållbar verksamhet utan att ha en negativ påverkan på lönsamheten. Det är kvalitativ metod som tillämpas i studien. Kvalitativ metod utgår från att undersöka problemet på djupet och kan även visa hur totalsituationen ser ut vilket kan vara till hjälp då undersökningen behandlar olika stora företag i olika branscher. Det har genomförts intervjuer med chefer inom aktuellt område på sju olika bolag som är noterade på Nasdaq OMX och finns på listorna large, mid eller small cap.  Till stöd för studien kommer problemet och empirin att analyseras utifrån intressentteorin och legitimitetsteorin då intressenter och legitimitet kan påverka hållbarhetsarbetet och lönsamheten i ett företag.  Studien visar att bolag måste ha en långsiktig syn på hållbarhetsarbete för att det ska kunna gynna både miljön och lönsamheten. För att kunna förena lönsamhet och hållbarhet är utbildning grundläggande för samtliga inom organisationen då hållbarhetsarbetet måste integreras i varje del för att det ska få bästa möjliga effekt. Den kostnad som uppstår vid implementering av hållbarhetsarbete är endast kortsiktig och ses också som det enda negativa med att arbeta hållbart.  Det har även visat sig att det finns en förväntan från intressenterna att bolagen ska arbeta hållbart. Genom att uppfylla den förväntan som finns skapas legitimitet och förtroende vilket i sin tur har en positiv inverkan på alla berörda parter. / Society has in recent decades begun to make more demands on companies to implement sustainability initiatives in their daily operations. However, there are companies that choose to ignore these expectations when they consider their sustainability efforts to have a negative impact on the profitability in form of increased costs, such as restructuring and education. The companies who have not chosen to work sustainably is the companies that do not have a long term view of sustainability efforts, nor knowledge of the benefits that it can lead to, both for the company itself, the environment and society. A study has shown that several listed companies in Sweden still has much to work within terms of sustainability. However, it raises awareness that companies can contribute to a more sustainable development. The research question that becomes pertinent is how listed companies in Sweden combines profitability and sustainability. The purpose of the study is to identify the factors that contribute to a sustainable business without having a negative impact on the profitability. It is a qualitative method used in the study. Qualitative method assumes that the problem should be investigated thoroughly and can also show the overall situation which can be helpful when the survey deals with various sized companies in various industries. The study is based on interviews with sustainability managers in seven companies listed on the Nasdaq OMX and in the lists large, mid or small cap. In support of the study, the problem and the empirical data will be analyzed based on the stakeholder theory and legitimacy theory, as stakeholders and legitimacy can affect the sustainability work and profitability of a company. The study shows that companies need to have a long term view on sustainability work for it to be beneficial for both the environment and the profitability. Education within the organization is fundamental in order to reconcile profitability and sustainability. To get the best effect, sustainability must be integrated into every part of the company. The cost incurred in the implementation of sustainability initiatives is only short term and is also seen as the only negative thing about working sustainably. It has also been shown that there is an expectation from stakeholders that companies are to work sustainably. By fulfilling the expectations, the sustainability work will create legitimacy and trust, which in turn has a positive impact on all stakeholders.

We provide a systematic comparison of the out-of-sample forecasts based on multivariate macroeconomic models and forecast combinations for the euro against the US dollar, the British pound, the Swiss franc and the Japanese yen. We use profit maximization measures based on directional accuracy and trading strategies in addition to standard loss minimization measures. When comparing predictive accuracy and profit measures, data snooping bias free tests are used. The results indicate that forecast combinations help to improve over benchmark trading strategies for the exchange rate against the US dollar and the British pound, although the excess return per unit of deviation is limited. For the euro against the Swiss franc or the Japanese yen, no evidence of generalized improvement in profit measures over the benchmark is found.

Environmental impact and management of energy is a highly topical issue in today's society. Climate impact must be reduced. The Government has set a target to reduce energy consumption in buildings by 20 % by 2020 and 50 % by 2050 compared to the energy use in 1995. With this in mind, we chose to examine how property owners can work on improving energy efficiency in existing apartment buildings. We also wanted to investigate profitability of different increasing energy efficiency measures and the calculation methods and the risk assessment performed by such investments. To tie in with government objectives, we also saw the possibilities of achieving these goals. 20 companies were interviewed, of which 14 were property owners and 6 were consulting firms that works with energy efficiency. All property owners were familiar with the importance of energy work but they worked very different with it. The interviewed companies work with energy efficiency measures in the building envelope, HVAC , household and residential electricity and solar energy. The companies have chosen to implement various extensive measures and outcome measures differ between objects of different conditions. Also the choice of calculation method for the calculation varied between companies. Much of the results were due to the tradition and resources. Many of the larger companies have come a long way in their work toward the energy targets and some already achieves the goals by 2020. Others are not as advanced, because they do not see sufficient profit to invest in energy efficiency measures.

A topical issue in financial economics is the development of appropriate stochastic dynamic models for banking items and behavior. The issue here is to fulfil the need to generalize the more traditional discrete-time models of banking activity to a Levy process setting. In this thesis, under the assumption that the loan market is imperfectly competitive, we investigate the evolution of banking items such as bank assets (cash, bonds, shares, Treasuries, reserves, loans and intangible assets), liabilities (demand deposits) and bank capital (bank equity, subordinate debt and loan loss reserves). Here we consider the influence of macroeconomic factors and profitability as well as its indicators return on assets (ROA) and return on equity (ROE). As far as bank assets are concerned, we note that loan pricing models usually reflect the financial funding cost, risk premium to compensate for the risk of default by the borrower, a premium reflecting market power exercised by the bank and the sensitivity of the cost of capital raised to changes in loans extended. On the other hand, loan losses can be associated with an offsetting expense called the loan loss provision (LLP), which is charged against Nett profit. This offset will reduce reported income but has no impact on taxes, although when the assets are finally written off, a tax-deductible expense is created. An important factor influencing loan loss provisioning is regulation and supervision. Measures of capital adequacy are generally calculated using the book values of assets and equity. The provisioning of loans and their associated write-offs will cause a decline in these capital adequacy measures, and may precipitate increased regulation by bank authorities. Greater level of regulation generally entail additional costs for the bank. Currently, this regulation mainly takes the form of the Basel II Capital Accord that has been implemented on the worldwide basis since 2008. It is clear that bank profitability is a major indicator of financial crises for households, companies and financial institutions. An example of this from the 2007-2008 subprime mortgage crisis (SMC) is the U.S. bank, Wachovia Corp., who reported a big loss as from the first quarter of 2007 and eventually was bought by the world's largest bank, Citigroup, on 29 September 2008. A further example from the SMC is that both the failure of the Lehman Brothers investment bank and the acquisition in September 2008 of Merrill Lynch and Bear Stearns by Bank of America and JP Morgan Chase, respectively, were preceded by a decrease in profitability and an increase in the price of loans and loan losses. The subprime mortgage crisis is characterized by contracted liquidity in the global credit markets and banking system. The level of liquidity in the banking sector affects the ability of banks to meet commitments as they become due without incurring substantial losses from liquidating less liquid assets. Liquidity, therefore, provides the defensive cash or near-cash resources to cover banks' liability. An undervaluation of real risk in the subprime market is cascading, rippling and ultimately severely adversely affecting the world economy. The downturn in the U.S. housing market, risky lending and borrowing practices, and excessive individual and corporate debt levels have caused multiple adverse effects tumbled as the US housing market slumped. Banks worldwide are hoarding cash and showing a growing reluctance to lend, driving rates that institutions charge to each other on loans to record highs. Also, global money markets are inoperative, forcing increased injections of cash from central banks. The crisis has passed through various stages, exposing pervasive weaknesses in the global financial system and regulatory framework. The stochastic dynamics of the aforementioned banking items assist in formulating a maximization problem that involves endogenous variables such as profit consumption, the value of the bank's investment in loans and provisions for loan losses as control variants. In particular, we demonstrate that the bank is able to maximize its expected utility of discounted profit consumption over a random time interval, [t,r], and terminal profit at time r. Here the term profit consumption refers to the consumption of the bank's profits by dividend payments on equity and interest and principal payments on subordinate debt. The associated Hamilton-Jacobi-Bellman (HJB) equation has a smooth solution when the optimal controls are computed by means of power, logarithmic and exponential utility functions. This enables us to make a direct comparison between the economic properties of the solutions for different choices of the utility function. In keeping with the main theme of this thesis, we simulate the financial indices ROE and ROA that are two measures of bank profitability. We further discuss optimization with power utility where we show the convergence of the Markov Chain Approximation Method (MCAM) and the impact of varying the model parameters in the form of loan loss severity, P, and loan loss frequency, <f>. We investigate the connections between the banking models and Basel II capital accord as well as the current subprime mortgage crises. As a way of conclusion, we provide remarks about the main issues discussed in the thesis and speculate about future research directions. The contents of this thesis is based on 3 peer-reviewed journal articles (see [105], [106] and [107]) and 1 peer-reviewed conference proceedings paper (see [104]). In addition, the paper [108] is currently being prepared for submission to an accredited journal. / Thesis (Ph.D. (Applied Mathematics))--North-West University, Potchefstroom Campus, 2009.

Literature on the divorce of ownership from control has emphasised the declining proportion of shares owned by salaried managers who control large companies. Because these salaried managers have negligible proprietarial interest in the companies they manage, some writers have suggested that they will have different motives to owner-managers. In particular, managers' direct pecuniary interests may cause them to pursue company growth at the expense of profit, for managers' salaries tend to be related to the size of the companies which they manage rather than the profitability of those companies. These alternate motivations were incorporated in various managerial theories of the firm developed in the late 1960's which emphasised company growth as a key objective. An investigation of the shareholdings and salaries of the directors of major British companies confirms that the proportion of total shares held by company directors has fallen over the years, though it is argued that shareholdings are still large enough to allow directors to exercise effective control over their companies. In addition, while the proportion of total shares held by directors is small, these shareholdings are often large in absolute terms and constitute a significant source of directors' income, though the size of directors' shareholdings varies considerably between industries. Combined dividend income and capital appreciation of shareholdings match the remuneration which directors receive as salary income. It is argued that these profit-related income elements are sufficiently large to cause directors to attach priority to profitability goals. This proposition is explored through statistical analysis of the relationship between directors' remuneration and company performance. Regression results show that as the definition of directors' remuneration is broadened to include dividends and capital appreciation as well as salary, company size variables diminish in importance as determinants of remuneration and profitability variables predominate. Managers do have an incentive to pursue profitability.

This dissertation examines four disadvantaged groups in the labour market from a variety of perspectives. Specifically, I looked into older workers, younger workers, nonstandard workers and female workers. In the first chapter, I examine the effects of Ontario eliminating mandatory retirement in 2006 on the labour force participation of older workers and the unemployment of younger workers. My second chapter examines the relationship between nonstandard employment and the subsequent workplace profitability. In my final chapter, I examine the interaction effect of employment status and gender on the issue of work hour mismatches. The first chapter examines the impact of recent labour policy change at a national/provincial level. I find positive and significant effects for the labour force participation rate of older workers in Ontario in the five years following the legislation change of banning mandatory retirement in Onatrio. Similar results are found for both men and women; however, the magnitude of this effect is somewhat smaller for men. In addition, the empirical analysis also reveals a short-run rise in the unemployment rate of younger workers. The second chapter examines the financial implication of nonstandard employment at an organizational level. The results suggest that nonstandard employment is positively associated with subsequent workplace profitability, after controlling for factors that might also affect profitability. Moreover, this significant positive relationship between nonstandard employment and subsequent profitability is primarily driven by capital intensive manufacturing, the real estate/rental/leasing, the retail/trade/consumer service, and the education and health services industries as well as smaller workplaces. Larger workplaces and the rest of the private sector do not display significant results. The final chapter looks into how employment status and gender systematically impact work hour preferences at an individual level. The findings indicate that there is a significant interaction effect between nonstandard employment and gender. Female nonstandard workers prefer to work more hours. Male workers, both nonstandard and standard, are more likely to prefer to work fewer or the same hours. These results conform to labour market trend of increasing labour force participation rates of females and a declining trend among males.

After a decade of reforming policy, building and developing the multi-sector market economy, Small and Medium Enterprises (SMEs) in Vietnam have developed strongly and contributed to creating employment, increasing GDP, and raising the nation’s volume of exports. However, SMEs have found difficulties on the way to development due to lack of management experience and financial resources, and due to uncertainty within the business environment. As a result, SMEs often faced obstacles during their operations. This thesis examines the relationship between financial management and profitability of SMEs to determine whether financial management practices and financial characteristics impact on SME profitability. Objectives of the thesis are (1) to investigate and describe features of financial management practices and financial characteristics of SMEs in Vietnam, (2) to develop and test a model of SME profitability, and (3) to contribute knowledge of the relationships between financial management and characteristics to improve SME profitability by using tools of efficient financial management. In terms of structure, the thesis has six chapters. The thesis begins by defining the research problem and questions, and providing a justification for the research study. Chapter one also reviews the research background, and presents definitions of terms, significance and scope of the study. Chapter two examines the economic background, business structure and the development of SMEs in Vietnam. This chapter also reviews previous research related to financial management for SMEs in Vietnam to identify gaps between financial management for SMEs in Vietnam and financial management for SMEs worldwide. Chapter three reviews financial management including financial management practices, financial characteristics and profitability of SMEs around the world, especially in the developed economies such as the United States of America (USA), the United Kingdom (UK), Australia and Canada. This review emphasizes profitability and the impact of financial management practices and financial characteristics on SME profitability. Objectives of this chapter are to review previous research related to the areas of financial management practices, financial characteristics, and profitability of SMEs and to build a model of the impact of financial management practices and financial characteristics on SME profitability. Chapter four discusses aspects of the research methodology including research design, data collection and data analysis methods, and hypothesis testing to support the model. Objectives of this chapter are: (1) to justify the research methodology of this study, (2) to explain research methodology used in the study, and (3) to demonstrate how research design, and data collection and analysis can be utilized in this study to answer the research questions outlined in the chapter 1. Data analysis and findings are presented in chapter five. This chapter presents descriptive findings of financial management practices, financial characteristics and SME profitability and findings of the research study related to testing the model of SME profitability. Objectives of this chapter are (1) to systematically present the descriptive findings of the research study, (2) to interpret significance of these findings based on data analysis, (3) to present the results of testing the model of SME profitability, and (4) to explain how the model, developed from a literature review, was supported by data analysis. Finally, the thesis ends with chapter six where conclusions are summarized and applications of the research findings are indicated for the financial management practitioners. The thesis provides descriptive findings of financial management practices and financial characteristics and demonstrates the simultaneous impact of financial management practices and financial characteristics on SME profitability. In addition, the research study provides a model of SME profitability, in which profitability was found to be related to financial management practices and financial characteristics. With the exception of debt ratios, all other variables including current ratio, total asset turnover, working capital management and short-term planning practices, fixed asset management and long-term planning practices, and financial and accounting information systems were found to be significantly related to SME profitability. With the findings as presented above, this research study provides many implications for financial management practices and contributes to knowledge of financial management of SMEs. The model of SME profitability can be used as guidance for actions to improve the profitability of SMEs in Vietnam.
