Improved shock-capturing of Jameson's scheme for the Euler equations

It is known that Jameson's scheme is a pseudo-second-order-accurate scheme for solving discrete conservation laws. The scheme contains a non-linear artificial dissipative flux which is designed to capture shocks. In this paper, it is shown that the, shock-capturing of Jameson's scheme for the Euler equations can be improved by replacing the Lax-Friedrichs' type of dissipative flux with Roe's dissipative flux. This replacement is at a moderate expense of the calculation time

The Role of Additionality in the EU Cohesion Policies: An Example of Firm-Level Investment Support

Additionality is one of the key principles driving the functioning of the EU Cohesion Policies (ECP). The present paper studies how additionality affects the distributional effects of the ECP. Using the example of the firm-level investment support, we analyse the role of additionality and co-financing rate in differently competitive markets. We find that the investment additionality and the level of competition importantly affect the distributional effects of the ECP. Imposing additionality to the ECP investments in a perfectly competitive environment causes distortions in the capital market and leads to lower welfare levels. In contrast, without the enforcement of additionality, the distortions are zero and the support fully benefits firms. In an imperfectly competitive environment the firm-level investment support may increase capital use and may be welfare increasing with and without the enforcement of the investment additionality.Additionality, EU Cohesion Policy, investment subsidy, regional development.
