  • Smiling Despite the Default: Default Risk and its Relation to Volatility Smirk

    Graduate thesis at the London School of Economics

    This study points out default risk as a potential explanation for the volatility skew in equity options. Using CDS spreads as a measure to account for default risk, for each firm, we run time series regressions of volatility skew to CDS spreads. We find that there is a significant positive relationship between the skew and default risk. Using the firm level variation in our estimates, we show that the effect of default risk on volatility skew is significantly higher for the firms with higher…

Using CDS spreads as a measure to account for default risk, for each firm, we run time series regressions of volatility skew to CDS spreads. We find that there is a significant positive relationship between the skew and default risk. Using the firm level variation in our estimates, we show that the effect of default risk on volatility skew is significantly higher for the firms with higher credit ratings. We also have weak evidence that more leveraged firms exploit a stronger positive relation between default risk and the skew.

  • The Causal Determinants of Popularity in Instagram

    As the social media becomes more and more prominent in our daily lives, the academic studies on various social platforms proliferate rapidly. Instagram is one of these platforms where people like photos of each other. In this paper, we endeavor to explore the factors that determine the number of likes each photo gets by running various regressions.

    As the social media becomes more and more prominent in our daily lives, the academic studies on various social platforms proliferate rapidly. Instagram is one of these platforms where people like photos of each other. In this paper, we endeavor to explore the factors that determine the number of likes each photo gets by running various regressions. According to our main findings, while factors such as the use of hashtags, selfies, nakedness, inclusion of a child and presence of a smile in photos increase the number of likes; those factors such as absence of face in photos and darkness decrease the number of likes.

  • The Impact of Middlemen on the Markets with Heterogeneously Informed Parties

    In this paper, we propose an alternative explanation for the presence of middlemen in markets from a microeconomic perspective. We created a game theoretical setting within which two heterogeneously informed players trade repeatedly both with and without the hypothetical middleman. The players don't know about each other's exact valuation. They only know the interval which contains the other player's valuation. However, the middleman knows the valuations of both parties and sets the price…

    In this paper, we propose an alternative explanation for the presence of middlemen in markets from a microeconomic perspective. We created a game theoretical setting within which two heterogeneously informed players trade repeatedly both with and without the hypothetical middleman. The players don't know about each other's exact valuation. They only know the interval which contains the other player's valuation. However, the middleman knows the valuations of both parties and sets the price accordingly. The theory suggests that if the sellers were to offer their pay-off maximizing prices, they would be better off compared to the case where the prices are offered by the middleman. However, in our experiment, we observed that the prices offered by the sellers deviated from the pay-off maximizing prices. Seller's pay-off increases when we include include the middleman. Concluding from the results of our experiment, we argue that the observed behaviour might explain why middlemen are still present in the real world markets.
