Thermodynamics of firms' growth

The distribution of firms' growth and firms' sizes is a topic under intense scrutiny. In this paper, we show that a thermodynamic model based on the maximum entropy principle, with dynamical prior information, can be constructed that adequately describes the dynamics and distribution of firms' growth. Our theoretical framework is tested against a comprehensive database of Spanish firms, which covers, to a very large extent, Spain's economic activity, with a total of 1 155 142 firms evolving along a full decade. We show that the empirical exponent of Pareto's law, a rule often observed in the rank distribution of large-size firms, is explained by the capacity of economic system for creating/destroying firms, and that can be used to measure the health of a capitalist-based economy. Indeed, our model predicts that when the exponent is larger than 1, creation of firms is favoured; when it is smaller than 1, destruction of firms is favoured instead; and when it equals 1 (matching Zipf's law), the system is in a full macroeconomic equilibrium, entailing ‘free’ creation and/or destruction of firms. For medium and smaller firm sizes, the dynamical regime changes, the whole distribution can no longer be fitted to a single simple analytical form and numerical prediction is required. Our model constitutes the basis for a full predictive framework regarding the economic evolution of an ensemble of firms. Such a structure can be potentially used to develop simulations and test hypothetical scenarios, such as economic crisis or the response to specific policy measures.

Three Challenges Europe Faces in Becomming a Big Data Market

Three Challenges Europe Faces in Becomming a Big Data Market | Big Data | Scoop.it
The European Commission is working hard on developing a competitive European Big Data market. Last week, as a result of this, the European Digital Forum convened the High-Level Roundtable on Europe’s Digital Future. Neelie Kroes, former vice-president of the European Commission and commissioner for the digital agenda (2009-2014), delivered a keynote and launched Digital Minds for a New Europe, an e-book featuring 44 essays by the world’s leading thinkers on the challenges ahead. I was asked to give my vision about how Europe can enable forward-looking, data-driven startups to unleash the vast potential of data. Here's how I think Europe should move forward:

Doctoral Program in Complexity Sciences

Doctoral Program in Complexity Sciences | Big Data | Scoop.it

The Doctoral Program in Complexity Sciences provides an integrated training that enable doctoral students understand the environment in which they live, by applying modelling methods and computer simulation, and solve complex problems using information technology, including support systems to organizational processes in complex environments. Developing these skills will enable the integration of multidisciplinary knowledge and the autonomously formulation of judgements from data that is often incomplete.


The Doctoral Program in Complexity Sciences is taught in ISCTE and FCUL. It has an international dimension based on a set of protocols to the Paris-Dauphine University (France), with the University of Savoie (France) and the Academy of Economic Studies of Bucharest (Romania). There are teachers of exchanges with the University Paul Sabatier in Toulouse (France), with the Open University (UK), with the University of Utrecht (Netherlands) and the University of Texas (USA).

 

The new curriculum comprehends a 1st curricular year and a 2nd and 3rd years mainly dedicated to research at PhD level. Students are invited to develop their research projects at LabMAg (FCUL, Lisbon), ISTAR (ISCTE-IUL, Lisbon), and IITGn (Gandhinagar, India).

 

A new class for the 1st curricular year will start in February 2016. Classes will take place on Tuesdays and Wednesdays, from 18h to 21h30.

 

Applications for the 1st curricular year are open until the 23rd of December, 2015. Applications are submitted through the form available at the ISCTE-IUL applications website.

Want to influence the world? Map reveals the best languages to speak

Want to influence the world? Map reveals the best languages to speak | Big Data | Scoop.it

Speak or write in English, and the world will hear you. Speak or write in Tamil or Portuguese, and you may have a harder time getting your message out. Now, a new method for mapping how information flows around the globe identifies the best languages to spread your ideas far and wide. One hint: If you’re considering a second language, try Spanish instead of Chinese.

 

The study was spurred by a conversation about an untranslated book, says Shahar Ronen, a Microsoft program manager whose Massachusetts Institute of Technology (MIT) master’s thesis formed the basis of the new work. A bilingual Hebrew-English speaker from Israel, he told his MIT adviser, César Hidalgo (himself a Spanish-English speaker), about a book written in Hebrew whose translation into English he wasn’t yet aware of. “I was able to bridge a certain culture gap because I was multilingual,” Ronen says. He began thinking about how to create worldwide maps of how multilingual people transmit information and ideas.

New method of measuring cultural transmission suggests some tongues spread ideas better than others
