Investment and Consumption with Regime-Switching Discount Rates

This paper considers the problem of consumption and investment in a financial market within a continuous time stochastic economy. The investor exhibits a change in the discount rate. The investment opportunities are a stock and a riskless account. The market coefficients and discount factor switch according to a finite state Markov chain. The change in the discount rate leads to time inconsistencies of the investor's decisions. The randomness in our model is driven by a Brownian motion and a Markov chain. Following Ekeland and Pirvu we introduce and characterize the subgame perfect strategies. Numerical experiments show the effect of time preference on subgame perfect strategies and the pre-commitment strategies.Comment: arXiv admin note: substantial text overlap with arXiv:1107.189

Principles and rules for defining of common consolidated tax base in the European Union

The "Common Consolidated Tax Base" system is an ambitious goal of the European Commission. Technical discussions related to this system were launched in September 2004, when was formed a working group to help the Commission to prepare a legislative proposal in this regard. Until now has been accurately defined the principles of the system and identified a number of operating rules. In this paper we propose to render some specific instances that demonstrate how the "Common Consolidated Tax Base" can achieve the objectives set by the Commission.common consolidated tax base, principles, tax mechanism

Investitiile imateriale si performantele IMM-urilor

Along time, the goal of intangible assets became very important for the activity and prosper¬ity of business. This matter is achieved as well as more and more the companies operate in a global economy which has as main base the digital revolution and information management. The increase of the immaterial investments percent requires evaluation and recognition criteria by knowledge, intelligence and human competence. But recently, the accounting standards were about to accord negligible atten¬tion or even totally ignored the appropriate modalities of report this category of assets. The accounting, obliged to bend to economic, financial and juridical logics, in a ,,Taylor" modality, presents an unreal image of the company economic life and particularly of investment activity. In a competitive environ¬ment, the reliability of future economic benefits, generated by investments, depends less on their material or immaterial nature and more on the characteristics of the market they operate on. These are just a few reflections which determined us to focus our attention to this thought-provoking domain of immaterial investments, appreciated as a potential for the company.intangible assets immaterial investments competences intelligence knowledge competences potential

STRATEGIC costs management at societies group level. Multicriterial model for optimization

In our opinion, the performances at group level must be analyzed differently, depending on the adopted strategy. Thus, we consider that a major problem of the accounting and cost control is their compatibility with the strategy. This is justified by the fact that a certain system, that can be an efficient instrument for assessing the performances of a group whose strategy is cost dominated, could cause malfunctions in a company that adopts a differentiation strategy. Because groups’ management currently faces a specific problem – adopting decisions when several objectives are followed simultaneously or the same objective common for more branches – we consider that, in such cases, the decisions cannot be based on a classic model of optimization of a single objective function. We consider that an optimization model with several objective functions, which aims at optimizing the costs for the subsidiaries and choosing a satisfactory solution for the company, is necessary.costs, the optimization of the costs, decision process, linear programming, games theory.
