Large-scale forecasting of large fluctuations using wavelet coherence and multifractal behavior and developing wavelet coherence for multiple time series

Oygur, Tunç

Shocks, jumps, booms, and busts are typical large fluctuation markers that appear in crisis. Identifying financial crises and estimating leading indicators with strong relations during crisis periods have an essential role in the literature. This thesis examines the dynamic co-movements of leading indicators' multifractal features to identify financial crises due to large fluctuations. The detected dynamic relationships predict leading indicators with scale-by-scale analysis and make large-scale predictions better than challenger models. As a natural result of these studies, the n-dimensional ...Daha fazlası

Emotion and cognition integration – The effect of anger on working memory

Gözütok, Emre

How systematic is default risk?

Dalgıç, Nihan

This study aims to provide an extensive analysis of systematic (market-wide) and systemic (sector-wide and industry-wide) components of the idiosyncratic default risk. We detect significant heterogeneity among the default risk structure of various industry groups. More specifically, the default probability of institutions affiliated with certain industry groups is more strongly linked to industry-wide risks while others are more heavily tied to sectorwide risks. We further show that systematic and systemic components of default risk alter also relative to up/down market cycles for each indust ...Daha fazlası

Global art market and art economy after 2000 and Turkey: The evolution, resilience, and global prominence of the Turkish art market

Üler Kaprol, Tuğçe

The term "market" has deep historical roots, evolving from a physical space for trade to an abstract concept symbolizing the exchange of goods and services. In the sociology of art, Pierre Bourdieu has shaped a distinctive path of research, emphasizing taste judgments, cultural power, and cultural capital as tools for social dominance. This foundation aids in understanding the intricacies of the art market. Over time, art has transformed into an alternative investment for corporate entities, wealth managers, banks, and individuals, driven by economic shifts since the 1980s. The 1980s saw the p ...Daha fazlası
