This paper employs mathematical modeling and algebraic approach to derive the optimal manufacturing batch size and number of shipment for a vendor-buyer integrated economic production quantity (EPQ) model with scrap. Unlike the conventional method by using differential calculus to determine replenishment lot size and optimal number of shipments for such an integrated system, this paper proposes...

The causation relationship between economic growth and military expenditures in developing countries has received growing focus in recent years. One of the arguments in this field is that military spending absorbs a significant proportion of the limited financial resources in LDCs. The present study examines the causal relation in two models: defense spending with total real economic growth and...

This paper investigates the relationship between neighbourhood ethnic and linguistic heterogeneity and the formation of an individual's local and general trust. A wide literature across economics and sociology has recognised the importance of trust in facilitating economic growth and development and it is therefore important to investigate elements of social organisation that encourage or inhib...

This paper studies an overlapping generations model with selfish agents, natural resources and human capital externalities. The initial result is to quantify the economic effects of intergenerational transfers by comparing a complete markets allocation with transfers to an allocation without transfers due to incomplete markets. The core contribution is then to show that a higher resource regene...

The theoretical richness and variety of the new growth literature can make it difficult to capture the essence of growth models. With this paper, we wish to provide one possible integrating view of the nature of the growth generating processes. Revisiting the models that constitute the core of growth theory, we expose analytically the main mechanisms through which long-run growth can be deliver...

This chapter introduces agent-based modeling as a methodology to study qualitative change in economic systems. The need to focus on qualitative developments is derived from evolutionary economics, where the quantitative orientation of mainstream economic approaches is strongly criticized. It is shown that agent-based models can cope with the challenges of an evolutionary setting and fulfill the...

Every dictator dislikes free media. Yet, many non-democratic countries have partially free or almost free media. In this paper, we develop a theory of media freedom in dictatorships and provide systematic statistical evidence in support of this theory. In our model, free media allow a dictator to provide incentives to bureaucrats and therefore to improve the quality of government. The importanc...

Previous research has shown that economic growth should help to reduce the rate of poverty. However, a number of recent studies find that the economic expansion of the 1980’s had no statistically significant effect on aggregate poverty. We show that a Fourier approximation provides a better empirical model of poverty than the standard linear model. It is noteworthy that the nonlinear specificat...
