Let $X$ be a mixed process, sum of a brownian motion and a renewal-reward process, and $\tau_{x}$ be the first passage time of a fixed level $x

Due to the introduction of new services, the volume of data transferred in mobile networks is rapidly growing and operators periodically face the necessity to upgrade their network. Such upgrades allow them to increase the capacity and provide adequate Quality of Service (QoS). In this paper we...

In the real investments literature, the investigated cash flow is assumed to follow some known stochastic process (e.g. Brownian motion) and the criterion to decide between investments is the discounted utility of their cash flows. However, for most new investments the investor may be ambiguous...

In the wake of the global change of a new accumulation regime in major capitalist economies, the opening up and liberalisation process of emerging economies from the 1980s has provoked great expectations that resulted in recurrent disappointing crises. Studied as a stylized fact, the Turkish...

A main purpose of our project is to examine the financial condition of 3 chosen companies: a financial institution, a non-profit organizations, as well as the production company. All companies are existing at the Polish market. To make the calculations and tests we used the method of John...

We introduce a new consistency condition for neutral social welfare functions, called hyperstability. A social welfare function a selects a complete weak order from a profile PN of linear orders over any finite set of alternatives, given N individuals. Each linear order P in PN generates a...

Investigations of long-run sustainability of joint ecological-economic systems highlight the pertinence of reconsidering "free disposal" assumptions that underpin Sraffian and von Neumann approaches to value and growth theory. We investigate joint-production time-paths for square systems A and B...

On démontre la stabilité de l'équilibre dans une économie walrasienne complètement décentralisée dans laquelle les prix sont fixés par les agents économiques et où échange et production ont lieu hors équilibre.
