diversity of repression: Measuring state repressive repertoires with events data / Bagozzi, Benjamin E ; Berliner, Daniel ; Welch, Ryan M   Journal Article
Berliner, Daniel Journal Article
0 Rating(s) & 0 Review(s)
Summary/Abstract Tactical repertoires of mobilization and repression play an essential role in understanding dynamics of political violence, yet existing quantitative approaches focus primarily on intensities or counts of repressive actions. We focus instead on the diversity of repression, and demonstrate a novel method of measuring repertoires of state repression using event data. We show that more repressive states are likely to employ more diverse repertoires of repression, rather than specializing narrowly in particularly coercive tactics. We demonstrate that, globally, repertoires of state repression are growing less diverse over time. Finally, in the Online appendix, we model repertoires of repression across countries and over time, finding evidence of broader repertoires during protest and civil war, but narrower under democratic regimes and international human rights treaties.

Efficiency of crude oil markets: evidences from informational entropy analysis / Ortiz-Cruz, Alejandro; Rodriguez, Eduardo; Ibarra-Valdez, Carlos; Alvarez-Ramirez, Jose   Journal Article
Ortiz-Cruz, Alejandro Journal Article

Publication 2012.
Summary/Abstract The role of crude oil as the main energy source for the global economic activity has motivated the discussion about the dynamics and causes of crude oil price changes. An accurate understanding of the issue should provide important guidelines for the design of optimal policies and government budget planning. Using daily data for WTI over the period January 1986-March 2011, we analyze the evolution of the informational complexity and efficiency for the crude oil market through multiscale entropy analysis. The results indicated that the crude oil market is informationally efficient over the scrutinized period except for two periods that correspond to the early 1990s and late 2000s US recessions. Overall, the results showed that deregulation has improved the operation of the market in the sense of making returns less predictable. On the other hand, there is some evidence that the probability of having a severe US economic recession increases as the informational efficiency decreases, which indicates that returns from crude oil markets are less uncertain during economic downturns.

Entropy and the trajectory of world politics: why polarity has become less meaningful / Schweller, Randall L   Journal Article
Schweller, Randall L Journal Article
0 Rating(s) & 0 Review(s)
Publication 2010.
Summary/Abstract The random and indeterminate nature of the current unipolar world suggests a condition of increasing entropy. There are two reasons for this claim. First, relative capability advantages under unipolarity do not translate as easily as they once did into power and influence over others. Second, systemic constraint is a property that limits actors' freedom of action by imposing costs and benefits on certain kinds of actions. Unlike past multipolar and bipolar systems, the current unipolar system exerts only weak, if any, systemic constraints on the unipolar power and all other actors as well. Thus, polarity has become a largely meaningless concept. Today, system process rather than structure best explains international politics, and this process is one of entropy. Finally, I suggest two pathways from unipolarity to a more balanced system: one is fairly consistent with standard balance-of-power realism but adds an ideational component; the other restores equilibrium by means of entropy.
