A tourism growth model

Two processes can be used to summarize the productive-mix of a tourism-led economy: the lack of a significant secondary sector and strong tertiarization. Both developments have had significant consequences for productivity gains that, as shown by empirical research, are key to understanding economic progress. In fact, this productivity has been predominantly concentrated in the industrial sector while services have relied more on factor accumulation. However, this varying economic pattern has permitted long-lasting economic growth in current tourism-led economies. This article develops a theoretical dynamic economic model (a dynamic CGE model) to explain the beginning, development and long-term growth consequences of tourism-led economies.

AN ECONOMIC MODEL OF STUDENT LEARNING

We develop a dynamic economic model based on contemporary understanding of learning and motivation. The model and resulting comparative static analysis show the instructor's role in providing a productive learning environment. Instructors should set the complexity of course assignments and assessments to be consistent with student preparedness. Learning is enhanced when the rate of change in challenge is based on the rate of change of how rapidly students are learning. Instructors steer students toward a productive trajectory with tasks that cause students to work hard and by consistently providing feedback and fostering a culture of learning.

A Commentary on “Recovery from Catastrophe and Building Back Better (Takeuchi and Tanaka, 2016)” – Structure of Damage of Production Capital Stock on Normative Economic Process

In the field of disaster prevention, disaster loss is often classified into “direct loss” and “indirect loss.” As such, “total loss” is often calculated as a sum of “direct loss” and “indirect loss,” where “direct loss” is defined as a “loss of capital (assets) as a stock” and “indirect loss” is defined as “loss arising out of decline in postdisaster production as a flow.” However, the loss here is calculated twice. The calculation is incorrect if “indirect loss” refers to, in particular, the lost profit of a firm that has lost a production facility that is considered as a stock. The reason is that the “value of capital stock” is nothing but the present value of a product that the stock will produce in the future. Therefore, an “indirect loss” defined in the above manner corresponds to a decrease in stock value. Using a dynamic economic model, this article provides a basic structure, “value of loss in capital stock lost by a disaster” = “total decline of production after a disaster.” This article also presents a relational expression in consideration of the restoration cost of a production facility, and concludes that a more multifaceted and functional damage information system needs to be developed in the future.

A dynamic economic model of criminal activity in the criminal law

Poverty and crime are two major problem areas. The economic theory of crime shows a direct correlation between poverty and crime. In this study, we propose a model that shows the correlation between poverty and crime. Then we obtain the dynamic system of the proposed model. In the next step, we will compute the reproductive number by finding the maximum eigenvalue of Jacobian matrix to study of stability and un-stability of the presented model.
