Complex economic models often lack the structure for the application of standard techniques in monotone comparative statics. Generalized monotonicity analysis (GMA) extends the available methods in several directions. First, it provides a way of finding parameter moves that yield monotonicity of model solutions. Second, it allows studying the monotonicity of functions or subsets of variables. T...

In the near future, energy conservation and pollution reduction became two of the most significant factors in economic development and social circulate. For analyzing the issue, several models were applied involving the fields of mathematical optimization, economics theory, dynamics model and industrial management. Specifically, they are MARKAL model, Input-Output model, LEAP model and Systemic...

The view of animals as optimizers is extremely important in many parts of biology, and is represented in a variety of theoretical models. Current developments in animal welfare create a need for a new theoretical model, which treats the animal as acting optimally in its choice of a sequence of behaviours, and places as few restrictions as possible on what quantity is being maximized. The intent...

The federal government maintains large quantities of medical supplies in stock as part of its Strategic National Stockpile (SNS) to protect the American public in case of a public health emergency. Managing these large perishable inventories effectively can help reduce the cost of the SNS and improves national security. In this work, we propose a modified Economic Manufacturing Quantity (EMQ) m...

A general discrete-time stochastic control model is developed which encompasses many wellknown economic models. In the context of the general model, sufficient conditions are derived for the equivalence and approximate equivalence of myopic (sequential single-period) and global (simultaneous multi-period) expected return maximization. A bound provided for the global return loss resulting from m...
