Essays In Credit Portfolio Management

Tyagi, Vikrant. 2010. Essays In Credit Portfolio Management. Doctoral Dissertation, Cornell University.

The current financial crisis has lessons for three areas of credit portfolio management. First, the credit crisis has highlighted the need to manage the funding risk of a bank. Second, it has highlighted the need to manage the underwriting risk of debt syndications. Finally, it has suggested the need to understand the drivers of relationship banking. The first paper in this dissertation develops an empirically grounded model to manage the funding risk of a bank. The second paper develops an option pricing framework to manage the underwriting risk in debt syndications. The last paper in this dissertation uses a proprietary dataset to study the empirical determinants of relationship banking benefits.

Three Essays In Banking Sector Of Thailand

Mahathanaseth, Itthipong. 2011. Three Essays In Banking Sector Of Thailand. Doctoral Dissertation, Cornell University.

This dissertation consists of three essays. The first essay examines the cost efficiency and production technology in the banking sector of Thailand using a stochastic frontier approach. The empirical results indicate that banks with lower Non-performing-loan to-total-loan ratio, higher equity-to-total-asset ratio, higher liquid-asset-to-total-asset ratio, and more branches are likely to be more efficient. The second essay investigates the degree of competition in the banking industry using the new empirical industrial organization approach. The empirical results indicate that, despite the Thailand government's efforts to increase competition in the banking industry by relaxing restrictions on entry to the market after the financial crisis, the oligopolistic degree of the biggest four banks has intensified. The third essay links the results of the first and second essays, cost efficiency and competition in the banking sector, to the transmission mechanism of monetary policy in Thailand using Vector Autoregression approach. The empirical results indicate that an unexpected tightening monetary policy shock leads to higher financial costs in the banking industry, forcing banks to compete more fiercely and operate more efficiently, significantly helping strengthen the transmission of monetary policy. Hence, the policy implication is that Thai government should exert more effort to enhance efficiency and competition in the banking sector.

Banking across Borders

The study examines the internationalization strategies of the world’s largest banks between 1980 and 2000. These banks have dominated the internationalization of banking. For 44 banks, commonalities and differences are identified on the basis of a strategic typology developed for this study. The central research question deals with the effectiveness of internationalization. Using a self constructed internationalization database, differences are estimated between foreign and domestic performance, and the effects on shareholder return. A higher degree of internationalization has on average contributed negatively to bank performance. Similarly, shareholders have not gained by more internationalization. Banks who retreated from their internationalization or banks with a long established internationalization strategy generated the highest total shareholder return. Banks who (strongly) increased their internationalization generated the least returns. The study also addresses the future outlook for international banking - how will the internationalization of banks proceed? The potential for further financial deregulation in the home country, uncertainty on the international regulatory regime, and the business mix of the bank are likely drivers for the bank's future internationalization strategy and profitability enhancement.
