Next Generation Access Networks The Effects of Vertical Spillovers on Access and Innovation

We consider an upstream firm that sells a vital input to downstream firms. There are vertical spillovers and two different regulatory policies of the input price: cost oriented regulation and no-regulation. We also admit two alternative market structures: vertical integration and vertical separation. With this setting we study the effects of vertical spillovers on foreclosure and on the investment of the upstream firm. We conclude that foreclosure is not a necessary outcome. We also conclude that if the vertical spillovers are significant the standard conclusions about the effects of regulation on investment incentives do not always hold.

Carnegie Mellon Portugal Program at Mostra Portugal Tecnológico

Carnegie Mellon|Portugal Program at “Mostra Portugal Tecnológico 2009”
Portugal Tecnológico

The Carnegie Mellon | Portugal Partnership will participate on the technological fair “Mostra Portugal Tecnológico” (stand nº 1A06A), from October 7 th until October 10 th in FIL, Lisboa. A major event that demonstrates accomplishments of Portugal in the fields of Information and Communication Technologies.

With free entrance, the visitors will have the opportunity to see what Portuguese universities, public organizations, and companies are doing in the various areas that could help Portugal and its regions to gain comparative advantages.

The Carnegie Mellon|Portugal Program will show some videos about the research that is being conducted in the scope of the partnership, as well as about the events that were organized this year.

Lee Branstetter Presents Lecture to Development Solutions Organization – ICTI: Information & Communication Technologies Institute – Carnegie Mellon University

Lee Branstetter Presents Lecture to Development Solutions Organization
Lee BranstetterLee Branstetter, associate professor of economics and public policy at Carnegie Mellon’s Heinz School of Policy and Management and its Department of Social and Decision Sciences, will present a talk for the Development Solutions Organization, “Will India and China dominate the 21st Century Global Economy?”

The talk and reception will be held October 14, 4:30, Doherty Hall A310. Branstetter, who is also a Principal Investigator for Carnegie Mellon|Portugal’s joint doctoral program in Social and Decision Sciences, has research interests in the areas of international economics, the economics of technological innovation, industrial organization, East Asian economic growth, and the Japanese economy.

Branstetter will discuss how in recent years, respected economists from the private and public sectors have predicted that China and India could eclipse the United States in economic size over the course of the 21st century. Branstetter explains why standard models of economic growth imply that this outcome is plausible and even likely. He goes on to demonstrate why this outcome could raise the living standards of American families in the 21st century, even as it forces a radical change in America’s place in the world.

Lee Branstetter is a highly cited expert on international economics and the economics of innovation. Prior to his appointment at Carnegie Mellon, Branstetter was the Daniel Stanton Associate Professor of Business and Director of the International Business Program at Columbia Business School. He holds a Ph.D. in Economics from Harvard University.

The Development Solutions Organization (DSO) is hosting this event as part of a series to introduce students to opportunities to work on impactful global projects and to build a community around this vision. View the DSO’s Facebook page for this event for additional information.

José Manuel Neto Vieira, Departament of Electronics – ICTI: Information & Communication Technologies Institute – Carnegie Mellon University

José Manuel Neto Vieira, Departament of Electronics, Telecommunications and Information Technology at the University of Aveiro, gives talk on “Compressed Sensing and Digital Fountains”
José Manuel Neto VieiraJosé Manuel Neto Vieira recently visited Carnegie Mellon’s Pittsburgh campus. One of the highlights of Vieira’s visit is a talk he presented titled, “Compressed Sensing and Digital Fountains.” The talk was on April 15, 2008. Vieira is a faculty member with the Instituto de Engenharia Electrónica e Telemática de Aveiro and the Departamento de Electrónica, Telecomunicações e Informática at the University of Aveiro.

Talk abstract:
Blahut was one of the first researchers to notice the tight connections between signal processing and coding areas. Coding using real or complex fields was, until a few years ago, a mere academic topic without any interesting applications. Recently, Elad and Donoho discovered an efficient method to recover a sparse signal from a set of random linear combination of its samples. This discovery created a compressed sensing area and new ways of sampling and representing signals. Digital Fountain coding is a new concept where the traditional paradigm of transmitting information as an ordered stream of packets is changed to one where the user must receive a sufficient amount of packets in order to reconstruct the original information. In this tutorial talk we will introduce these two concepts, Compressed Sensing and Digital Fountains, and how they are related. An overview of the applications of Digital Fountains will also be presented.

José Vieira received a diploma in Electrical Engineering in 1988 from the University of Coimbra. In 2000 he received a PhD degree in Electrical Engineering from the University of Aveiro. He has been a professor of electrical engineering at the University of Aveiro since 1991, and is also a researcher at the IEETA Institute. He has been the President of the Portuguese chapter of the AES since 2003. His major research interests are in the fields of digital audio, signal reconstruction, digital fountains and compressed sensing.

Post Doctoral Academy in Mathematics – ICTI: Information & Communication Technologies Institute – Carnegie Mellon University

Post Doctoral Academy in Mathematics
July 7-8, 2009
Instituto Superior Técnico, Lisbon, Portugal
This Academy brings together all post-docs of the Mathematics programs of both the Carnegie Mellon|Portugal and UTAustin|Portugal partnerships.
“In the Academy we will have two courses by leading mathematicians as well as presentations by the post-docs and we expect to attract to the audience both senior faculty as well as junior faculty and advanced graduate students”, explains Diogo Gomes, scientific director of Carnegie Mellon|Portugal Program.

This year the main topic of the Academy is Applied Analysis and Partial Differential equations. “We will have courses by Luis Caffarelli from University of Texas at Austin and Panagiotis Souganidis from the University of Chicago”, says Diogo Gomes adding “we are also planning a presentation by the leaders of the research projects in Mathematics under these partnerships. We hope to get the new post-docs actively involved in the research activities at Portuguese institutions. As such, we believe that activities such as this Academy are essential for the integration of the post-docs hired under these programs in ongoing research projects.”

Who is Luis Caffarelli?

Luis Caffarelli is a Sid W. Richardson Foundation Regents Chair at the University of Texas at Austin, and has been awarded in 2009 the AMS Leroy P. Steele Prize for Lifetime Achievement. He is also the Director of Mathematics at the University of Texas at Austin of the CoLab – UTAustin|Portugal partnership program.

Who is Panagiotis Souganidis?

Panagiotis Souganidis is a Charles H. Swift Professor of Mathematics at the University of Chicago. He has been awarded a Presidential Young Investigator Award (1987), an Alfred P. Sloan Fellowship (1989) and the 1996 Bodossaki Foundation Academic Prize, which is awarded to outstanding Greek scholars under the age of 40.
