Financial crises result from a catastrophic combination of actions. Vast stock market datasets offer us a window into some of the actions that have led to these crises. Here, we investigate whether data generated through Internet usage contain traces of attempts to gather information before...

Crises in financial markets affect humans worldwide. Detailed market data on trading decisions reflect some of the complex human behavior that has led to these crises. We suggest that massive new data sources resulting from human interaction with the Internet may offer a new perspective on the...

Due to the lack of Purchasing Power Parities (PPPs) at regional level, regional Gross Domestic Product (GDP) figures have been traditionally adjusted using national PPPs. The simplifying assumption that all regions of a country have the same cost of living, and implicitly that there are no...

Society’s increasing interactions with technology are creating extensive "digital traces" of our collective human behavior. These new data sources are fueling the rapid development of the new field of computational social science. To investigate user attention to the Hurricane Sandy disaster...

This paper compares productivity developments across industrial countries based on official OECD data in the business sector. It discusses the uncertainties surrounding the measurement of both productivity levels and productivity growth, and then focuses on changes in productivity growth. The...

Being able to infer the number of people in a specific area is of extreme importance for the avoidance of crowd disasters and to facilitate emergency evacuations. Here, using a football stadium and an airport as case studies, we present evidence of a strong relationship between the number of...

Seasonal influenza outbreaks and pandemics of new strains of the influenza virus affect humans around the globe. However, traditional systems for measuring the spread of flu infections deliver results with one or two weeks delay. Recent research suggests that data on queries made to the search...

This paper compares productivity developments across industrial countries based on official OECD data in the business sector. It discusses the uncertainties surrounding the measurement of both productivity levels and productivity growth, and then focuses on changes in productivity growth. The...

This paper examines conditional convergence of OECD countries in gross domestic product (GDP) and health care expenditure (HCE) per capita. It presents estimation of the augmented Solow growth model suggested by Mankiw, Romer and Weil (1992) to explain variation in output and expenditure per...

This paper aims to determine and analyse the typology and intensity of the economic growth through an approach to the structure of the allometric models, previously developed by biologists. It could be important for political decision-takers to know the type of growth since it allows the...
