Forecasting in a risky situation is a very important function for managers to assist in decision making. One of the fluctuated markets in stock exchange market is chemical market. In this research the target item for prediction is PET (Poly Ethylene Terephthalate) which is the raw material for...

Calculating return periods and critical layers (i.e., multivariate quantile curves) in a multivariate environment is a di cult problem. A possible consistent theoretical framework for the calculation of the return period, in a multi-dimensional environment, is essentially based on the notion of...

Small to medium enterprises (SME) are frequently associated with high levels of innovation. However, it is difficult for such firms to fully assess the merits of a particular innovation. This study examined the risk-return profile of future investment in innovation by SME with respect to...

The METSTOR project offers a methodology to look for potentially interesting CO2 storage areas in France at the initial stage, before the "site selection" step. Our tool, embodied in a Geographic Information System, is based on an interactive map of CO2 storage capacities. Other relevant...

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.
