In late 1994 when the Mexican financial crisis occurred, many emerging economies experienced negative returns. For instance, Latin American markets, Hong Kong, Singapore, Korea and Thailand all showed stock price declines of 15% to 30%. Similarly, the Asian Crisis of 1997, the Russian Crisis of 1998, and the Brazilian Crisis of 1999 have all brought about significant negative returns in many seemingly unrelated emerging markets. Based on these figures, it was found worthwhile to study the spread of financial crises among international stock exchanges, in a quest to reach clues on ءcontagious volatility̕. This study aims to analyze the nature and spread of international financial crises. Remaining within its scope, the study on contagion of volatility studied 72 positive and negative events and reached the conclusion that markets move together in times of crisis, with outstanding increases in their correlations. This finding shows that the benefits of international diversification are reduced because of increasing correlations among markets during events. Another striking finding was that, though at a lesser extent, the same co-movement was observed with upturns in markets. It was also observed that volatility tends to be higher within periods of negative and positive events analyzed in the study. As country groups that move together in crisis periods were analyzed, it seemed that economic and trade linkages were an influencing factor in their behavior. In the light of these findings, the possible mechanisms of the spread of contagion and policies that could be implemented to withstand it were discussed.

Essays on empirical testing of financialization of commodities
Ordu, Beyza Mina; Oran, Adil; Department of Business Administration (2017)
Over the last decade commodity derivatives market experienced a significant influx of financial institutions, which is a phenomenon referred to as financialization of commodities. The main purpose of this thesis is to investigate whether financialization bolstered the connectedness between US stock and commodity markets. Connectedness can occur in forms of either spillover or co-movement and hence we analyze each form in two essays. In the first essay, we investigate volatility spillover between 25 commodit...
Memorandum on a new financial architecture and new regulations
Mittnik, Stefan; Nell, Edward; Platen, Eckhart; Semmler, Willi; Chappe, Raphaele (Orta Doğu Teknik Üniversitesi (Ankara, Turkey), 2009-6-1)
The financial crisis is global and is deeply rooted in a decade-long misuse of the financial market for rent-seeking. The financial industry has largely abandoned its role as a service industry, supposedly charging reasonable fees for the services of spreading risk and allocating capital and credit. Instead it provides a market for corporate control –mergers and acquisitions– and a casino for betting on or hedging practically any kind of risk –the derivatives market–.
RMARS: Robustification of multivariate adaptive regression spline under polyhedral uncertainty
Ozmen, Ayse; Weber, Gerhard Wilhelm (Elsevier BV, 2014-03-15)
Since, with increased volatility and further uncertainties, financial crises translated a high "noise" within data from financial markets and economies into the related models, recent years' events in the financial world have led to radically untrustworthy representations of the future. Hence, robustification started to attract more attention in finance. The presence of noise and data uncertainty raises critical problems to be dealt with on the theoretical and computational side. For immunizing against para...
An Investigation on the nature of the idiosyncratic risk of stock portfolios
Kocaarslan, Barış; Soytaş, Uğur; Department of Business Administration (2018)
In this study, based on sound economic theories, two economic transmission channels are identified to investigate the impacts of changes in funding liquidity conditions in interbank loan markets and the reserve currency (US dollar) value on the idiosyncratic portfolio-level risks. Controlling for business cycles, we find that a deterioration in funding liquidity conditions increases the idiosyncratic risk of high-risk portfolios more than that of less risky portfolios. This increase is stronger when the idi...
EXAMINATION OF BOND RISK PREMIA FROM THE BANKING PERSPECTIVE
Orhan, Selim; Danışoğlu, Seza; Department of Financial Mathematics (2022-5-10)
Banks are considered as the marginal and sophisticated investors of financial markets. This is evident in the Haddad and Sraer (2020) study that examines the US government bond excess returns. This study extends the Haddad/Sraer analysis to the Turkish government bond market. According to the forecasting results, exposure ratio provides explanatory power over bond excess returns, especially for longer maturities. On the other hand, output gap and industrial growth present strong in-sample forecasting power ...
