Orientation: The 2007–2008 global financial crisis (GFC) represented a negative economic shock that financially constrained most firms globally.Research purpose: This study investigated the impact of GFC on firms’ speed adjustment (SOA) towards target leverage and whether this is good descriptor corporate financing for Johannesburg Stock Exchange (JSE)-listed nonfinancial firms.Motivation study...

Empirical data shows that current account has the property of mean-reversion and the speed of current account convergence is heterogenous across countries. In order to explore the factors which affect the current account adjustment speed of a small country, this paper builds up a model to study how current account would be affected by factors such as labor supply and monetary policies. We found...

The processing power of mobile devices is continuously increasing. In this paper we perform a case study in which we assess three different programming models that can be used to leverage this processing power for compute intensive tasks. We use an imaging algorithm and compare a reference implementation of this algorithm based on OpenCV with a multi threaded RenderScript implementation and an ...

This paper examines how asset risk impacts corporate investment and financing decisions. We derive a general model that incorporates risk, adjustment cost, and depreciation features of assets-in-place into investment decisions. The model suggests that the risk and adjustment cost of assets-in-place reduce both corporate investment and financing. We empirically test the model in a panel of US fi...

There is strong evidence indicating that the existing measures which are designed to detect a single high leverage collinearity-reducing observation are not effective in the presence of multiple high leverage collinearity-reducing observations. In this paper, we propose a cutoff point for a newly developed high leverage collinearity-influential measure δ D i and two existing measures δi and li ...

In this report, we propose a robust mixture of regression based on t-distribution by extending the mixture of t-distributions proposed by Peel and McLachlan (2000) to the regression setting. This new mixture of regression model is robust to outliers in y direction but not robust to the outliers with high leverage points. In order to combat this, we also propose a modified version of the propose...
