In general, risk of an extreme outcome in financial markets can be expressed as a function of the tail copula of a high-dimensional vector after standardizing marginals. Hence it is of importance to model and estimate tail copulas. Even for moderate dimension, nonparametrically estimating a tail...

Microsimulations make use of quantitative methods to analyze complex phenomena in populations. They allow modeling socioeconomic systems based on micro-level units such as individuals, households, or institutional entities. However, conducting a microsimulation study can be challenging. It often...

When running agent-based simulations using ready-made components, one usually faces heterogenity problems both for the agents implementation and for the underlying platform. To circumvent these kind of hindrances, we introduce a wrapper technique for mapping the functionality of agents living in...

Das ZEW und die Universität Mannheim haben mit ihrem Computersimulationsprogramm "European TaxAnalyzer" die Auswirkungen der Steuerreformen in Deutschland und in Frankreich für eine repräsentative mittelständische Kapitalgesellschaft des verarbeitenden Gewerbes untersucht...

This paper shows an environment for agent-based simulation of corporate strategy.

We study the influence of technological efficiency and organizational inertia on the emergence of competition when firms decide myopically. Using an agent-based computer simulation model, we observe the competitive reaction of a former monopolist to the advent of a new competitor.(...)

We study an agency model, in which the principal has only incomplete information about the agent's preferences, in a dynamic setting. Through repeated interaction with the agent, the principal learns about the agent's preferences and can thus adjust the inventive system. In a dynamic...

A key problem of construction firms' management and economy is organization of effective participation in public tenders. The direct executor, who determines the price of the contract, may be interested in obtaining as many contracts as possible. It means that his strategic behavior in tender...

In diesem Beitrag stellen wir ein Konzept greifbarer, gegenständlicher Benutzungsschnittstellen vor. Es werdenÜbergänge zwischen dem Modellieren im Realen und dem Erstellen virtueller Modelle geschaffen. Synchronzum gegenständlichen Modell entsteht ein virtuelles Abbild, das für Simulation,...
