We propose a method to correct estimates from historical linked data for bias arising from type-I error--"false matches." We estimate the rate of false matching from the disagreement rate in characteristics that should agree across the two linked datasets. Combined with an understanding of the...

Broad, long-term financial and economic datasets are a scarce resource, in particular in the European context. In this paper, we present an approach for an extensible, i.e. adaptable to future changes in technologies and sources, data model that may constitute a basis for digitized and...

We provide data and code that successfully reproduces nearly all crosssectional stock return predictors. Our 319 characteristics draw from previous meta-studies, but we differ by comparing our t-stats to the original papers' results. For the 161 characteristics that were clearly significant in...

Managing big data and data analytics poses unique challenges to many organisations. The effective use of such data is essential to planning business strategies and ensuring future corporate success. Organizations need to know how best to capitalise on the information that they have access to....

This review article, which was solicited by the Geneva Risk and Insurance Review, surveys work that has been done using an empirical framework for analyzing selection in insurance markets developed by Einav, Finkelstein, and Cullen (2010). We briefly review that framework, and then describe a...

Daten und ihre ökonomischen Auswirkungen durchdringen alle Bereiche der Wirtschaft. Die sogenannte Datenökonomie ist kein neuer Wirtschaftszweig, sondern eher eine ständige Herausforderung für alle Unternehmen, im Rahmen einer neuen Dimension der Wertschöpfung wettbewerbsfähig und...

We provide data and code that successfully reproduces nearly all cross-sectional stock return predictors. Unlike most metastudies, we carefully examine the original papers to determine whether our predictability tests should produce t-stats above 1.96. For the 180 predictors that were clearly...

Durable identification and access to datasets, especially to research datasets, become increasingly important. This is mainly driven by the explosive dataset growth in the current age. Although the Internet was originally founded as a large-scale end-to-end communication platform, in the current...

This paper explores the long-standing empirical fact of increased trading volume around news releases through the lens of canonical models of gradual information diffusion and differences of opinion. I use a unique dataset of clicks on news by key finance professionals to distinguish between...

Mobile devices have become ubiquitous not only in the consumer domain but also support the digitalization of business operations though business apps. Many frameworks for programming cross-platform apps have been proposed, but only few modeling approaches exist that focus on platform-agnostic...

The G-20 Data Gaps Initiative (DGI), which aimed at addressing the information needs that were revealed by the 2007/2008 global financial crisis, concluded its first phase and started a second phase (DGI-2) with the endorsement of G-20 Finance Ministers and Central Bank Governors in September...

Die Arbeit beschäftigt sich mit Ansätzen zur Unterstützung von datengetriebenen Prozessschritten in Simulationsstudien. Der Lösungsansatz besteht darin, vorrangig das Mengenproblem einer zu geringen bzw. zu hohen Menge an Inputdaten, mangelnder Datenvarianz bzw. schlechter Qualität zu...

Service-orientierte Architekturen haben sich als Architekturstil für die Entwicklung von Geschäftsanwendungen etabliert. Dementsprechend spielen Geschäftsprozessmodelle eine zentrale Rolle sowohl für die Beschreibung fachlicher Anforderungen als auch für die Spezifikation der erforderlichen...
