Essays on International Financial Regulation

The first chapter of this dissertation examines the incentives of national regulators to coordinate regulatory policies in the presence of systemic risk in global financial markets. In a two-country and three-period model, correlated asset fire sales by banks generate systemic risk across national financial markets. Relaxing regulatory standards in one country increases both the cost and the severity of crises for both countries in this framework. In the absence of coordination independent regulators choose inefficiently low level of macro-prudential regulation. A central regulator internalizes the systemic risk and thereby can improve the welfare of coordinating countries. Symmetric countries always benefit from coordination. Asymmetric countries choose different levels of macro-prudential regulation when they act independently. Common central regulation will voluntarily emerge only between sufficiently similar countries. The second chapter investigates the empirical determinants of cross country and over time variation in the stringency of bank capital regulations. Despite the extensive attention that the Basel capital adequacy standards received internationally, there exists significant variation in the implementation of these standards across countries. Furthermore, a significant number of countries increase or decrease the stringency of capital regulations over time. The chapter investigates the empirical determinants of the variation that is seen in the data based on the theories of bank capital regulation. The results provide strong evidence that countries with high average returns to investment choose less stringent capital regulation standards. There is also some evidence that capital regulations are less stringent in countries with higher ratio of government ownership of banks where government ownership is used as a proxy for the regulatory capture: the degree to which regulators are captured by the financial institutions under their control. The results provide somewhat weaker evidence that countries with more concentrated banking sectors impose less strict capital regulation standards.Doctor of Philosoph

Non-price competition in credit card markets through bundling and bank level benefits

The attempts to explain the high and sticky credit card rates have given rise to a vast literature on credit card markets. This paper endeavors to explain the rates in the Turkish market using measures of non-price competition. In this market, issuers compete monopolistically by differentiating their credit card products. The fact that credit cards and all other banking services are perceived as a bundle by consumers allows banks to deploy also bank level characteristics to differentiate their credit cards. Thus, credit card rates are expected to be affected by the features and service quality of banks. Panel data estimations also control for various costs associated with credit card lending. The results show significant and robust effects of the non-price competition variables on credit card rates.Credit Cards, Monopolistic Competition, Product Differentiation, Bundling, Bank Pricing Behavior, Regulation

The Failure of Price Competition In The Turkish Credit Card Market

The failure of competition and the consequent high and sticky interest rates in credit card markets have been the subject of a considerable amount of debate and research lately. This paper presents the first regression testing for the existence of price competition in a credit card market to be estimated free of dynamic panel bias using recent quarterly data from Turkey. The estimation reveals that even though the effect of the cost of funds on credit card rates is statistically significant, it is very weak. The paper thus provides empirical evidence for the failure of price competition in the Turkish credit card market.Credit Cards, Price Competition, System GMM, Banking
