In this study it is shown that the nontrivial hyperbolic fixed point of a nonlinear dynamical system, which is formulated by means of the adaptive expectations, corresponds to the unstable equilibrium of Harrod. We prove that this nonlinear dynamical (in the sense of Harrod) model is structurally stable under suitable economic conditions. In the case of structural stability, small changes of the functions (C1-perturbations of the vector field) describing the expected and the true time variation of the capital coefficients do not influence the qualitative properties of the endogenous variables, that is, although the trajectories may slightly change, their structure is the same as that of the unperturbed one, and therefore these models are suitable for long-time predictions. In this situation the critique of Lucas or Engel is not valid. There is no topological conjugacy between the perturbed and unperturbed models; the change of the growth rate between two levels may require different times for the perturbed and unperturbed models.

A szerző cikkében a projektfinanszírozás különleges ismertetőjegyeit kívánja bemutatni – úgymint a projektfinanszírozás fejlődését, a projektfinanszírozás és a vállalatfinanszírozás fontosabb különbségeit, valamint a sikeres projektfinanszírozás előfeltételeit. Ezen kívül foglalkozik még a projektfinanszírozás során alkalmazott pénzügyi mutatószámrendszer, e finanszírozási forma lehetséges hitel- és tőkeforrásai, továbbá a projektfinanszírozás során alkalmazott biztosítékok köre. Végezetül pedig a kivitelezési és üzemeltetési kockázatot elemzi, mint a projektfinanszírozás egyik legfontosabb kockázati tényezőjét. _____ In this article the author presents the special features of project finance, such as the development of project financing, important differences of project finance and corporate finance, as well as the preconditions for successful project financing. The author demonstrates the financial scorecards which are used in project finance, possible debt and equity sources of this financial form, and the securities which are used in the project finance. Finally, he analyzes the construction and operational risk, as one of the major risk factors for project finance.
