Depois dos acontecimentos em Londres, penso ser pertinente e uma forma de debater/agregar as notícias que vão acontecendo sobre os movimentos sociais.

...The data shows a clear link between the magnitude of expenditure cutbacks and increases in social unrest. With every additional percentage point of GDP in spending cuts, the risk of unrest increases. As a first pass at the data, Figure 1 examines the relationship between fiscal adjustment episodes and the
number of incidents indicating instability (CHAOS). CHAOS is the sum of demonstrations, riots, strikes, assassinations, and attempted revolutions in a single year in each country. The first set of five bars show the frequencies conditional on the size of budget cuts. When expenditure is increasing, the average country-year unit of observation in our data registers less than 1.5 events. When expenditure cuts reach 1% or more of GDP, this grows to nearly 2 events, a relative increase by almost a third compared to the periods of budget expansion. As cuts intensify, the frequency of disturbances rises.
Once austerity measures involve expenditure reductions by 5% or more, there are more than 3 events per year and country -- twice as many as in times of expenditure increases.

Austerity and Anarchy: Budget Cuts and Social Unrest in Europe, 1919-2009, by Jacopo Ponticelli and Hans-Joachim Voth, Discussion Paper No. 8513, August 2011, Centre for Economic Policy

Research: Abstract Does fiscal consolidation lead to social unrest? From the end of the Weimar Republic in Germany in the 1930s to anti-government demonstrations in Greece in 2010-11, austerity has tended to go hand in hand with politically
motivated violence and social instability. In this paper, we assemble cross-country evidence for the period 1919 to the present, and examine the extent to which societies become unstable after budget cuts. The results show a clear positive correlation between fiscal retrenchment and instability. We test if the relationship simply reflects economic downturns, and conclude that this is not the key factor. We also analyze interactions with various economic and political variables. While autocracies and democracies show a broadly similar responses to budget cuts, countries with more constraints on the executive are less likely to see unrest as a result of austerity measures. Growing media penetration does not lead to a stronger effect of cut-backs on the level of unrest.
