Equilibria protect against crisis. All disciplines of sciences have the objective to create equilibria. But economics are not successful in this point. Here a simple equilibrium model based on a wage-price-rule is demonstrated. Economics are able to create economic equilibria by using this rule. But in economic systems there are a lot of rules, especially in accounting, which make economic equilibria impossible. These rules must be changed. If it is possible to create economic equilibria, the side-effect is the realization of economic sustainability.

This advanced textbook aims at providing a simple but fully operational introduction to applied general equilibrium. General equilibrium is the backbone of modern economic analysis and as such generation after generation of economics students are introduced to it. As an analytical tool in economics, general equilibrium provides one of the most complete views of an economy since it incorporates all economic agents (households, firms, government, foreign sector) in an integrated way that is compatible with microtheory and microdata. The integration of theory and data handling is required for successful modeling but it requires a double ability that is not found in standard books. With this book we aim at filling the gap and provide advanced students with the required tools, from the building of consistent and applicable general equilibrium models to the interpretation of the results that ensue from the adoption of policies. The topics include: model design, model development, computer code examples, calibration and data adjustments, practical policy examples.
This text considers a number of adjustment processes in different economic models and investigates their dynamical behaviour in order to approach the question of how economic equilibria are attained. The theory of non linear dynamics is used to analyze the dynamics of the different economic models.
The concept of equilibrium is fundamental to economic theory, according to which, it exists when supply and demand are balanced. Equilibrium Models in Economics critically examines the major problematic assumptions employed to build equilibrium models. It gives particular attention to the assumptions used to characterize learning, knowledge and expectations.
General Equilibrium Theory: An Introduction presents the mathematical economic theory of price determination and resource allocation from elementary to advanced levels, suitable for advanced undergraduates and graduate students of economics. This Arrow-Debreu model (known for two of its most prominent founders, both Nobel Laureates) is the basis of modern price theory and of a wide range of applications. The text starts with elementary models: Robinson Crusoe, the Edgeworth Box, and a 2-commodity 2-household 2-firm model. It gives a brief introduction to the mathematics used in the field (continuity, convexity, separation theorems, Brouwer fixed-point theorem, point-to-set mappings, and Shapley-Folkman theorem). It then presents the mathematical general equilibrium model in progressively more general settings, including point-valued, set-valued, and nonconvex set-valued demand and supply. Existence of general equilibrium, fundamental theorems of welfare economics, core convergence, and futures markets with time and uncertainty are treated fully. The new edition updates discussion throughout and expands the number and variety of exercises. It offers a revised and extended treatment of core convergence, including the case of non-convex preferences, and introduces the investigation of approximate equilibrium with U-shaped curves and non-convex preferences.
