    The Stock and Cds Market Consequences of Political Uncertainty: The Arab Spring
    (Routledge Journals, Taylor & Francis Ltd, 2022) Savaser, Tanseli; Usul, Naime; Tanyeri, Basak
    We investigate how political unrest affects asset prices in the context of the Arab Spring. Abnormal returns in the major stock-market indices of Arab Spring countries average -1.1% on key days of Arab Spring and abnormal changes in credit default spreads average 1.4%. There is significant reaction to region wide as well as local protests indicating a spillover with protests in neighboring countries affecting investors' perception of local political instability and the pricing of assets. Once protests start locally, investors start paying more attention to what is happening at home than in the region. The significant stock market reaction to region-wide protests in Arab Spring countries indicates a spill-over where investors price an increase in the probability of political turmoil in one country when there are protests in neighboring countries. The decline in stock market indices coupled with the increase in credit default spreads indicates that investors anticipate and ex-ante price how current political uncertainty will affect firm value.

    Reexamining the Ppp Hypothesis: a Nonlinear Asymmetric Heterogeneous Panel Unit Root Test
    (Elsevier, 2014) Omay, Tolga; Emirmahmutoglu, Furkan
    In this study, we re-examine the PPP hypothesis in the light of the new developments in the unit root testing literature. The recent theoretical findings have pointed out that the real exchange rate series exhibit asymmetric nonlinear behavior. A unit root test applied to analyze the PPP hypothesis therefore, should also take into account this asymmetry inherent in the real exchange rate. Different unit root tests that consider the presence of these data features have been developed in the time series literature. However, a true attempt to test the PPP hypothesis should take a panel data approach. To this end, we propose a nonlinear heterogeneous panel unit root test where the alternative hypothesis allows for symmetric or asymmetric exponential smooth transition autoregressive nonlinearity and provide its finite sample properties. We apply our test to the real exchange rates of the 15 European Union countries against the US dollar. While the results of the linear and symmetric nonlinear heterogeneous panel unit root tests are against the PPP hypothesis, the asymmetric nonlinear heterogeneous panel test that we propose gives support for the PPP hypothesis as expected. Therefore, the conclusions drawn from the linear panel unit root tests or the nonlinear panel unit root tests that do not take asymmetry into account might be misleading. (C) 2014 Elsevier B.V.

    An Empirical Analysis of Household Education Expenditures in Turkey
    (Pergamon-elsevier Science Ltd, 2016) Cilasun, Seyit Mumin; Acar, Elif Oznur; Gunalp, Burak
    Using Turkish Household Budget Surveys from 2003, 2007 and 2012, this paper investigates the determinants of household education expenditures within an Engel curve framework. In particular, we estimate Tobit regressions of real educational expenditures by income groups using a number of household characteristics (i.e. rural residence, employment status, age, educational attainment of the household head, household size, share of female students and primary school students in the household, and total number of students in the household) to examine if and to what extent the determinants of educational expenditures differ by income groups; income elasticities of educational spending evolves over time; and children from middle-class and poor families can benefit enough from educational opportunities. The estimated expenditure elasticities have lower values for the top- and the bottom income quartiles while they have larger values for the middle-income quartiles. The results also show that for all income groups the expenditure elasticity of education increases over time, indicating that Turkish households allocates greater share of their budgets to education expenditures.

    Elliott Wave Principle and the Corresponding Fractional Brownian Motion in Stock Markets: Evidence From Nikkei 225 Index
    (Pergamon-elsevier Science Ltd, 2016) Ilalan, Deniz
    This paper examines one of the vital technical analysis indicators known as the Elliott wave principle. Since these waves have a fractal nature with patterns that are not exact, we first determine the dimension of them. Our second aim is to find a linkage between Elliott wave principle and fractional Brownian motion via comparing their Hausdorff dimensions. Thirdly, we consider the Nikkei 225 index during Japan asset price bubble, which is a perfect example of an Elliott wave. (C) 2016 Elsevier Ltd. All rights reserved.
