We study policies that are aimed at retaining a migrant workforce in a Gulf State while introducing a tax on migrant earnings. We single out Qatar as a case study. We consider two types of migrants: target migrants, and non-target migrants. If migrants are target migrants, we show that in order...

The aim of this paper is to observe the respondents' (second-year students') perceptions regarding the mind map tool application in the classes of the course Mathematical Methods, and with its application to learn the course material. A survey was conducted for this research. Based on the...

Unemployment is a serious challenge that has been rising day by day. Skill development and creation of employment opportunities are key factors to address youth unemployment. This study emphasizes on the need for job-oriented education and to link education to employment. This study derives a...

In this paper we argue, that the interaction of technology and economic policy regulations in the energy sector may be described by the so-called slow-fast class of dynamical systems. It is known that such systems may exhibit the blue sky catastrophe, a special type of bifurcation. Application...

This paper describes the implementation in GAMS of an economic equilibrium model based on the GTAP version 9 dataset. We call this model and the ancillary programming tools GTAPINGAMS, version 9. Relative to previous installments of GTAPINGAMS, an innovation in this model is that it can easily...

We study policies that are aimed at retaining a migrant workforce in a Gulf State while introducing a tax on migrant earnings. We single out Qatar as a case study. We consider two types of migrants: target migrants, and non-target migrants. If migrants are target migrants, we show that in order...

We bridge mathematical number theory with that of optimal control and show that a generalised Fibonacci sequence enters the control function of finite horizon dynamic optimisation problems with one state and one control variable. In particular, we show that the recursive expression describing...

This paper reviews approaches used for evaluating the performance of local or regional innovation systems. This evaluation is performed by a benchmarking approach in which a frontier production function can be determined, based on a knowledge production function relating innovation inputs and...

The Blinder-Oaxaca decomposition technique is widely used to identify and quantify the separate contributions of group differences in measurable characteristics, such as education, experience, marital status, and geographical differences to racial and gender gaps in outcomes. The technique...

In this note, a class of nonlinear dynamic models under rational expectations is studied. A particular solution is found using a model reference adaptive technique via an extended Kalman filtering algorithm, for which initial conditions knowledge only is required.
