Stochastic Volatility (SV) models play an integral role in modeling time varyingvolatility, with widespread application in finance. Due to the absence of a closed form likelihoodfunction, estimation is a challenging problem. In the presence of outliers, and the highkurtosis prevalent in...

The arena of strategic competition between the US and China is expandable from international politics, trade and commerce to finance. What would happen if financial sanctions against China are imposed by the US? Would US financial sanctions lead to a sudden outflow of foreign capital and a...

This study examines the effect of board size on credit risk with bank ownership, bank size and bank age acting as controls for the first time in the Ghanaian Banking Sector. Using Quantile Regression modelling, data was obtained from 12 universal Banks in Ghana over the period from 2011 to 2018...

Having highly educated workers can be beneficial for organizations in terms of innovation and problem-solving capabilities, however when underpaid and underemployed, overeducated workers may experience feelings of frustration and stagnation as they are unable to fully utilize their skills and...

In vielen Anwendungen ist es notwendig, die stochastische Schwankungen der maximalen Abweichungen der nichtparametrischen Schätzer von Quantil zu wissen, zB um die verschiedene parametrische Modelle zu überprüfen. Einheitliche Konfidenzbänder sind daher für nichtparametrische Quantil...

Let (X1, Y1), . . ., (Xn, Yn) be i.i.d. rvs and let l(x) be the unknown p-quantile regression curve of Y on X. A quantile-smoother ln(x) is a localised, nonlinear estimator of l(x). The strong uniform consistency rate is established under general conditions. In many applications it is necessary...

The publication of the OECD report on the PISA 2000 study induced a public outcry in Germany.On average,German students participating in this standardized test performed considerably below the OECD average and substantially worse than those of other European countries,like Finland or...

The issue of technological unemployment receives perennial popular attention. Although there are previous empirical investigations that have focused on the relationship between innovation and employment, the originality of our approach lies in our choice of method. We focus on four 2-digit...

In this paper uniform confidence bands are constructed for nonparametric quantile estimates of regression functions. The method is based on the bootstrap, where resampling is done from a suitably estimated empirical density function (edf) for residuals. It is known that the approximation error...

This paper investigates the male wage inequality and its evolution over the 1994-2002 period in Turkey by estimating Mincerian wage equations using OLS and quantile regression techniques. Male wage inequality is high in Turkey. While it declined at the lower end of the wage distribution it...
