The model considered here will be formulated in relation to the “fishing problem,” even if other applications of it are much more obvious. The angler goes fishing, using various techniques, and has at most two fishing rods. He buys a fishing pass for a fixed time. The fish are caught using...

In the dynamic two-sided market environment, overpricing one side of the market not only discourages demand on that side but also discourages participation on the other side. Over time, this process can lead to a death spiral. This paper develops a dynamic structural model of the video game...

A company’s performance significantly depends on how well a company manages its finances keeping in view the short term hurdles and long term goals. One objective of financial statement analysis is to determine firm value. Research suggests that a firm’s value is a function of the...

Here we prove the goodness property of adaptive rolling plans in a multisector optimal growth model under decreasing returns in deterministic environment. Goodness is achieved as a result of fast convergence (at an asymptotically geometric rate) of the rolling plan to balanced growth path....

This paper is about finding a solution to a transport problem, using visual programming applications, with one of the specialty software – Visual Basic. Among company’s spendings there are product transport spendings suported by economic agent in his way from each producers to beneficiaries....

In quantitative approach to decision making, a possible point of view for portfolio optimization is to model a portfolio in terms of a linear program. In this approach a linear programming model is in form of continuous non-negative variables instead of integer non-negative variables. In some...

The EU statistics reveal over 19 million active enterprises within the EU-27’s nonfinancial business economy (defined as industry construction, distributive trades and services, and therefore excluding financial and public services) in 2004. About one third (32.5%) were active in the...

A Really GENERAL Decomposition Algorithm for Very Large Linear Optimization Problems Proven theory as Regards Optimality and Finality Advantageous for very large problems with a rather small percentage of real variables in the optimal solution - Simplex method is used as a calculating...

In this paper, we examine main properties of the Constant Proportion Portfolio Insurance (CPPI) strategy, when trading in continuous-time is not allowed. We focus instead on stochastic-time rebalancing. We prove that investor's tolerance determines crucially portfolio performance, in particular...

The Ramsey model of economic growth is revisited from the perspective of viability theory. The Ramsey model, augmented with minimal consumption and sustainability criteria, becomes a viability problem. The framework allows for a clear picture of optimal viable, optimal nonviable, and viable...
