Incorporating the advantages of clickers and mobile devices to teach Economics to non-economists

Abstract In the twenty-first century, teaching practitioners in higher education (HE) have found themselves confronted with more challenges to help students engage in learning. Particularly, one of the main problems with the traditional lecture format to teach non-economists economics is that students tend to lack interest in the subject and therefore have a low level of engagement. Student response systems (i.e. “clickers”) have been used in classes for about 20 years and become more popular on many college campuses. Many studies reveal that clicker technology offers great promise in increasing students’ participation and engagement in lectures. Meanwhile, thanks to fast development of mobile technology, personal mobile devices can be integrated with clicker systems into teaching and learning with improved features. The programme we used and found as a very useful interactive teaching tool for learning is called Kahoot!. This paper offers a brief guidance on how to use Kahoot! to encourage active learning and engage non-economics majors in learning economics. Meanwhile, the existing relevant literature with regard to the use of clickers in HE is highlighted. In addition, the effectiveness of using Kahoot! in teaching economics to non-economists is evaluated by a student survey.

How reliable are budget sustainability tests? A case study for Greece

In this paper, we try to answer if the empirical evidence on the Greek fiscal policy has been consistent with the government intertemporal budget constraint during two tested periods, 1833 to 2009 and 1960 to 2009. The recent Greek debt crisis provides a unique opportunity to test whether sustainability tests produce what they ought to produce: We know that the Greek debt is unsustainable, so do the sustainability tests show the same? We use several common approaches such as Johansen approach, DOLS, Engle-Granger approach, Bohn test and finally Trehan-Walsh approach. Our results are mixed and in contrast with our expectations, because the majority of the tests indicate sustainable fiscal policy in both tested periods. One reason for the non-performance of the sustainability tests may be that they do not include information provided by rating agencies (which may not always be rational). Another important limitation of the present value budget constraint is the assumption of infinite growth of the economy. Additionally, the budget deficit is one of the most important fiscal instruments, and based on previous data processes.
