    Population Density Index and Its Use for Distribution of Covid-19: a Case Study Using Turkish Data
    (Elsevier, 2021-02-01) Başer, Onur
    Since March 2020, many countries around the world have been experiencing a large outbreak of a novel coronavirus (2019-nCoV). Because there is a higher rate of contact between humans in cities with higher population weighted densities, Covid-19 spreads faster in these areas. In this study, we examined the relationship between population weighted density and the spread of Covid-19. Using data from Turkey, we calculated the elasticity of Covid-19 spread with respect to population weighted density to be 0.67 after controlling for other factors. In addition to the density, the proportion of people over 65, the per capita GDP, and the number of total health care workers in each city positively contributed to the case numbers, while education level and temperature had a negative effect. We suggested a policy measure on how to transfer health care workers from different areas to the areas with a possibility of wide spread.

    Contagion Effects of U.s. Dollar and Chinese Yuan in Forward and Spot Foreign Exchange Markets
    (Elsevier, 2017-04-01) Kılıç, Erdem
    Financial contagion in forex markets is modeled by the application of a bivariate Hawkes stochastic jumpprocess. The self-exciting and mutually exciting properties of the jump-clustering model allow for illustratinginternal and cross-sectional transmission processes. The results obtained suggest stronger effects from US tomutual markets than in the reverse case. Cross-sectional excitation dynamics in the spot markets are larger thanin the forward markets. As a central result, we can observe that the results for the Hawkes-model parameters aremore significant in the forward markets. Transmission dynamics beyond volatility determine the likelihood ofcontagion occurrence. The significance of the decay parameters towards the long term jump intensities supportsthe importance of abrupt fluctuations in the contagion discourse.
