Critique of neoclassical economics is presented and contrasted with the more realistic assumptions made by an complex adaptive systems and evolutionary approach.
This is an introductory level core course in macroeconomics for those expecting to take further courses in economics. It provides a theoretical and applied approach of introductory macroeconomics, with an international perspective and applications to account for the growing importance of the global economy and the rising openness of economies.
Kilian de Ridder argumentiert in diesem Text, dass die EZB in ihrer aktuellen Konstruktion eine Institution ist, die aus heute überholten Theorien heraus entstanden ist. Die EZB hat das Mandat der Preisstabilität, was bedeutet, sie zielt auf eine niedrige, aber positive Inflation von 2 Prozent ab. Das hauptsächliche Instrument, das wir ihr für die Erfüllung dieses Mandats an die Hand gegeben haben, ist der Leitzins. Dieser stellt sich als überraschend unpraktisch für dieses Ziel heraus, weil er keine spezifischen Sektoren adressieren kann, sondern nur die gesamte Wirtschaft.
Modern authors have identified a variety of striking economic patterns, most importantly those involving the distribution of incomes and profit rates. In recent times, the econophysics literature has demonstrated that bottom incomes follow an exponential distribution, top incomes follow a Pareto, profit rates display a tent-shaped distribution. This paper is concerned with the theory underlying various explanations of these phenomena. Traditional econophysics relies on energy-conserving “particle collision” models in which simulation is often used to derive a stationary distribution. Those in the Jaynesian tradition rely on entropy maximization, subject to certain constraints, to infer the final distribution. This paper argues that economic phenomena should be derived as results of explicit economic processes. For instance, the entry and exit process motivated by supply decisions of firms underlies the drift-diffusion form of wage, interest and profit rates arbitrage. These processes give rise to stationary distributions that turn out to be also entropy maximizing. In arbitrage approach, entropy maximization is a result. In the Jaynesian approaches, entropy maximization is the means.
