Data insufficiency and reporting threshold are two main issues in operational risk modelling. When these conditions are present, maximum likelihood estimation (MLE) may produce very poor parameter estimates. In this study, we first investigate four methods to estimate the parameters of truncated...

Reproducibility is an absolute necessity in experimental sciences. In fact, the randomness of scientific findings based on P-values, that are the vast majority, should be taken into account. When a significance threshold α is fixed, the outcome of the test has a Bernoullian nature, i.e. is in...

This book is an experiment: How much knowledge about "using machine learning in quantitative trading" is stored and easily retrieved from the weights of ChatGPT-4? It follows a previous and similar experiment illustrated in "From Data to Trade: A Machine Learning Approach to Quantitative...

We theoretically study how social information affects agents' search behavior and the resulting observable outcomes that identify search models. We generalize canonical empirical search models by allowing a share of agents in the population to observe some peers' choices. Social information...

Präsenzlücken entlang der Supply Chain sind ein häufig auftretendes Phänomen im Handel mit erheblichen Auswirkungen auf Umsatz und Gewinn. Vor diesem Hintergrund sind entscheidungsunterstützende Informationen zur Identifikation von Dauer und Ausmaß dieser Präsenzlücken, sowie über...

The Western Balkans integration within the EU has started a legal process which is the rejection of former communist legal/political approaches and the transformation of former communist institutions. Indeed, the EU agenda has brought vertical/horizontal integration and Europeanization of...

This note analyzes the distributional properties of Pareto Type III random variables. The orignal two parameters distribution proposed by Pareto is expanded in a three parameters version and both its density and characteristic function are derived. The analytic expression of the inverse...

We analyze the properties of multiperiod forecasts which are formulated by a number of companies for a fixed horizon ahead which moves each month one period closer and are collected and diffused each month by some polling agency. Some descriptive evidence and a formal model suggest that knowing...
