Die Digitalisierung der Ökonomie

Mariana Mazzucato explains how we lost sight of what value means and why we need to rethink our current financial systems so capitalism can be steered toward a bold, innovative and sustainable future that works for all of us.

Dabei ging es um verschiedene Formen von (ökonomischer) Ungleichheit, wie man diese erforschen kann und was sie für Auswirkungen hat. Insbesondere ging es um Miriams aktuelle Forschung zur Vermögensungleichheit und dem Gender Wealth Gap.

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.

Was sind Finanzmärkte, Hedgefonds und Schattenbanken? Über diese Fragen erläutert Brigitte Young die Funktionen von Finanzmärkten und Hedgefonds, sowie deren Dysfunktionen anhand prominenter Beispiele. Young geht zudem auf die Regulierung von Hedgefonds nach der Finanzkrise und den Zusammenhang zum Schattebankensystem ein. Zuletzt stellt sie die Frage, ob das Finanzsystem einen sozialen Nutzen hat.
