Will the New Ring Vaccination Stop the Spread of Ebola?

The World Health Organization (WHO) and news reports are describing the deployment of a new experimental vaccine for Ebola in the Democratic Republic of the Congo (DRC). Originally 4,000 doses were sent to the country, and while the number is growing to 8,000 or more, there are still not enough to widely inoculate the city of Mbandaka with a population of over a million. Reports describe how the vaccine will be used in a "ring vaccination" technique. In ring vaccination, those who are most likely to be infected receive the vaccine. Currently this is being done by inoculating the known contacts of the sick and the contacts of the contacts, as well as healthcare workers. Prior experiments suggest that the vaccine can prevent the disease in those individuals.

Innovation, Economic Complexity and Economic Geography Workshop

The workshop aims to bring together experienced researchers with young scholars in the fields of Innovation, Economic Complexity and Economic Geography to understand knowledge accumulation and spillovers through products, people and places. Those interested in interdisciplinary research, especially bridging a gap between these topics are strongly encouraged to apply.  Complementary to the workshops provided there will also be young scholar presentations where the invited speakers will provide feedback in their respective relevant sessions.

Symbolic Unity, Dynastic Continuity, and Countervailing Power: Monarchies, Republics, and the Economy

We investigate the implications of the persistence of traditional patterns of state organization by examining the relationship between property rights and the economy for monarchies and republics. We argue that, relative to republics, monarchies protect property rights to a greater extent by reducing the negative effects of internal conflict, executive tenure, and executive discretion. In turn, a better protection of property rights results in greater standards of living. Using panel data on 137 countries between 1900 and 2010, we formulate and test a model with endogenous variables. We find strong evidence that monarchies contribute to a greater protection of property rights and higher standards of living through each of the three theoretical mechanisms compared to all republics. We also find that democratic-constitutional monarchies perform better than non-democratic and absolute monarchies when it comes to offsetting the negative effects of the tenure and discretion of the executive branch. We discuss the implications of the persistence of traditional patterns of political authority and rule for political sociology and economic sociology.
