We take the model of Alfarano et al. (Journal of Economic Dynamics & Control 32, 2008, 101-136) as a prototype agent-based model that allows reproducing the main stylized facts of financial returns. The model does so by combining fundamental news driven by Brownian motion with a minimalistic...

We explore the issue of estimating a simple agent-based model of price formation in an asset market using the approach of Alfarano et al. (2008) as an example. Since we are able to derive various moment conditions for this model, we can apply generalized method of moments (GMM) estimation. We...

Estimation of agent-based models is currently an intense area of research. Recent contributions have to a large extent resorted to simulation-based methods mostly using some form of simulated method of moments estimation (SMM). There is, however, an entire branch of statistical methods that...

Bundeswirtschaftsministerin Brigitte Zypries hat beklagt, dass die Gesundheitswirtschaft zu den am wenigsten digitalisierten Branchen gehört, obwohl schon im Januar 2016 ein E-Health-Gesetz in Kraft getreten ist. Die Digitalisierung umfasst dabei verschiedene Bereiche: von der elektronischen...

In this paper, we investigate the temporal dynamics of correlations between sentiment indices worldwide. Employing the tools of Random Matrix Theory (RMT) and Principal Component Analysis (PCA), our paper aims to extract latent information embedded in the interactions between economic and...

We investigate the structural dependencies in the bank-firm credit market of Spain under a multilayer network perspective. In particular, the original bipartite network is decomposed into different layers representing different industrial sectors. We then study the correlations between layers...

The paper investigates paid work beyond retirement age in Germany and the UK. This comprises a combination of work, payments from a pension (or several pensions) and old age which is counter to the assumed finality of retirement and the corresponding standardised passage from end of work into...

This paper presents a generalization of Varian's original contribution on disequilibrium models characterized by sequential trading. By building up the model on the differentiation of regimes we make the subject more easily comparable to standard disequilibrium models. Compared to the latter...

In this paper an inflationary regime is added to the Metzlerian inventory cycle model. It is shown that for all originally instable parameter values the time paths are stabilized to limit cycle oscillations between the Keynesian and the inflationary regimes. This result is due to the fact that...
