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.

The aim of this diploma paper is to describe the mortgage market in the Czech Republic. Firstly, I have analysed the general situation which is connected with the issue of providing the mortgage credit in the Czech Republic. The next point is the analysis of market of flats and support of the flat's market. One of this product is mortgage credit. I have analysed the main economic values such as mortgage credit, mortgage interest, classified mortgage credit, business cycle, etc. Especially I discussed the household sector because we can see the biggest growth there. Finally, I have compared the mortgage market in the Czech Republic, in the European Union and in the United States of America. The mortgage crisis in the USA is an ongoing economic problem and it caused a global financial crisis during 2007 -- 2008.

This graduation theses is primarily focused on mortgage trends in the Czech Republic. In the first part of the work a mortgage is defined, also its brief history, processing, obtaining, paying, each providers, types and forms of state assistances. In the second part the mortgage market in the Czech Republich is described from the begining of providing to the present and also some market determinants which influence the trend. Then it is focused on the origin and the trend of a hypothecary crisis in the USA and its successive spread all over the world. Tendencies of the mortgage market trends are described here, too.

The goal of my thesis is to analyze anti-crisis measures of the hotel Westside located in the United States of America. The first chapter explains theoretical approaches to crisis and its impacts. It depicts crisis management approaches to successful crisis managing. In the next part of my thesis I look closer at the U.S. subprime mortgage crisis. I tried to show details of subprime mortgage crisis spreading into the financial sector and also its impacts on tourism industry. The last chapter of my thesis compares theoretical approaches with the real steps in the crisis. After analyzing the real hotel behavior, I can conclude the hotel managed the crisis successfully. Right identification of the crisis, choosing effective price strategy and additional financial resource utilization contributed to smooth managing of the crisis. There were mistakes made by human resources department. They made the impact of the crisis on the hotel bigger but their realizing taught the management of the hotel how to behave in the future.

The aim of this thesis is to compare the causes, course and effects of the mortgage crisis and the subsequent financial crisis in the USA and in the Czech Republic in the years 2000-2012. Conclusions comparisons show that the impact of the crisis on the economy of the Czech Republic were milder mainly due to readiness of Czech banks. Furthermore, this work analyzes a model example of choice of parameters mortgage loan from the client's perspective, focusing on the assessment of the advantages of combination mortgages and savings products. Based on the results of this analysis, the combination can be recommended, but with regard to the rates of appreciation achieved when saving resources. If the condition of compensation refinancing costs by the difference in interest rates is satisfied, it is also possible recommended this financial instrument to a qualified client. Finally, we completed the image of the Czech mortgage market by comparing the classical mortgage products in offer of several banks.

The subprime mortgage crisis and the resultant inflationary monetary policy in the USA have left the Chinese economy subject to four risks in particular. First, China's exports to the USA might continue to decline. Second, in the medium term, the higher US inflation rate will lead to a weak dollar, which will negatively affect China's exports. Third, in the long term, when the US Federal Reserve decreases money supply to control inflation, the US economy might enter another recession, hurting China's exports further. Fourth, China's foreign exchange reserve assets might suffer heavy losses when the US inflation rate rises. Conventional foreign exchange investment strategies are insufficient for dealing with these four risks. Investment by China in the major US banks is suggested in the present paper. This strategy would mitigate if not eliminate all four risks. China could gain considerable financial returns on investments with only moderate risk.

This thesis demonstrates that consumer leverage can contribute to financial crises such as the subprime mortgage crisis characterised by increased bankruptcy prospects and tightened credit access. A recession may follow even when the leveraged sector is not a production sector and can be triggered by seeming positive events such as a technological innovation and a relaxation of borrowing conditions. The first preliminary chapter updates the Bernanke, Gertler and Gilchrist (1999) approach with financial frictions in the production sector to a two-sector model with consumption and housing. It shows that credit frictions in the capital financing decisions of housing firms are not sufficient to capture the negative consumer experience with falling housing prices and relaxed credit access during the recession. The second chapter brings the model closer to the subprime mortgage crisis by shifting credit constraints to the consumer mortgage market. Increased supply of houses lowers asset prices and reduces the value of the real estate collateral used in the mortgage which in turn worsens the leverage of indebted consumers. A relaxation of borrowing conditions turns credit-constrained households into a potential source of disturbances themselves when market optimism allows them to raise their leverage with little downpayment. Both cases demonstrate that although households are not production agents, their worsening debt levels can trigger a lasting financial downturn. The third chapter develops a chained mortgage contracts model where both homeowner consumers and the financial institutions that securitize their mortgage loan are credit-constrained. Adding credit constraints to the financial sector that provides housing mortgages creates opportunities for risk sharing where banks shift some of the downturn onto indebted consumers in order to hasten their own recovery. This consequence is especially evident in the case of relaxed credit access for banks. Financial institutions repair their debt position relatively fast at the expense of consumers whose borrowing ability is squeezed for a long period despite the fact that they may not be the source of the disturbance. The result mirrors the recent subprime mortgage crisis characterised by a sharp but brief decline for banks and a protracted recovery for mortgaged households.

This graduation thesis focuses on analyzing the impact(s) of the recent American mortgage crisis. The main goal is to study measures that have been taken to overcome this crisis andv evaluate them. The thesis is divided into four parts. The aim of the first part is to quantify the size of the United States housing bubble. The second part brings in the estimates of losses to individual financial institutions in the USA. The third part concentrates on detailed analysis of the arrangements that have been used to overcome mortgage crisis and consequential financial crisis. The last part compares the measures taken in order to solve the recent crisis with the ones that had been taken to overcome the Great Depression.

Dissertation deals with the Federal reserve system, which is the central Bank of the United states of America. The dissertation is supposed to analyze monetary politics of FED with regard to the possible connection of this institution with the last financial crisis. Chapter nbr. I. introduces short history of the central banking in the USA, the situation before FED was created, circumstances with the enactment of Federal Reserve act from 1913, followed by foundation of FED and first of all about its task during the period of Great depression in the 30th of the 20th century. Enclosed is the overview of critical economical opinions how the FED was functioning. The second part of the dissertation describes the monetary politics of FED before the crisis years 2000-2007. It evaluates the main steps the FED undertook to prevent or alleviate the incomming crisis. Further it evaluates these steps with recommendations of renowned and respected economists. Next chapter deals with the mortgage market crisis and with the monetary politics of FED between the years 2007-2011. This chapter also describes different situation of FED and European central bank and their monetary politics as a reaction to the mortgage crisis. Fourth and last chapter is aimed at the possible cause of the financial crisis and present development of FED.

Loans originated to borrowers with lower incomes and/or lower credit scores are classified as subprime. The spatial distribution of subprime loans is alarmingly concentrated in minority-dominated and low-income areas. Beginning in mid 2006 the subprime mortgage market began to see elevated levels of delinquent and defaulted loans. The causes are many but generally traced to the beginning of the reset periods for adjustable rate mortgages and the evaporation of demand for securitized subprime mortgages. As delinquent and default rates in subprime mortgages rise, areas with a concentration of high-risk borrowers are at risk to decline. The decline can be measured across four different groups of factors that indicate the health of a community. The four groups are: physical, institutional, socioeconomic and the residential body. The residential body factor group refers to the citizens of a community and their civic involvement. The analysis uses binary logistic regression to identify communities that are commonly associated with subprime mortgage defaults. Subprime loans in the ten-county Atlanta Metropolitan Area are the focus of the study. The analysis treats each census tract in the ten counties as an individual community. The sample loans are geocoded to the census tract level allowing defaulted loans to be tied to communities and their characteristics. The data is collected from a variety of sources including the U.S. Census Bureau, the Atlanta Regional Commission and RR Donnelley s Credit Risk Management database. The results indicate that the probability of subprime mortgage defaults are associated with higher vacancy rates, population loss, declining property tax revenues, depreciating property values, and declining owner reinvestment in their properties. Potential spill over impacts to the community include higher crime rates, decreased school funding and degradation of public infrastructure.
