Federalism as an effective antidote to terrorism
Many governments as well as terrorist experts see the use of military and police forces as the only way to effectively counter terrorism. The most effective negative sanctions are considered to be military strikes, aggressive actions (including kidnapping and killing) against individuals known or suspected of being terrorists, or against persons supporting and harboring terrorists. Overt and covert military and paramilitary action is also thought advisable to pre-empt and prevent actions by terrorist groups, as well as against states suspected of hosting or tolerating terrorists. This paper argues that decentralization constitutes a powerful antidote as it strongly reduces the incentives for terrorists to attack and because the expected damage suffered is much smaller than in a centralized society. It moreover strengthens society, as economic, political and social decentralization (or polycentricity) is an essential element of a free and vigorous society. This in turn makes a society less vulnerable to terrorist attacks. Indeed, terrorism has no chance of success against a society that actively guards its fundamental liberal institutions, of which decentralized decision-making forms an essential part
WMAP extragalactic point sources as potential Space VLBI calibrators
The point source list of the Wilkinson Microwave Anisotropy Probe (WMAP) is a
uniform, all-sky catalogue of bright sources with flux density measurements at
high (up to 94 GHz) radio frequencies. We investigated the five-year WMAP list
to compile a new catalogue of bright and compact extragalactic radio sources to
be potentially studied with Very Long Baseline Interferometry at millimeter
wavelengths (mm-VLBI) and Space VLBI (SVLBI). After comparing the WMAP data
with the existing mm-VLBI catalogues, we sorted out the yet unexplored sources.
Using the 41, 61 and 94 GHz WMAP flux densities, we calculated the spectral
indices. By collecting optical identifications, lower-frequency radio flux
densities and VLBI images from the literature, we created a list of objects
which have not been investigated with VLBI at 86 GHz before. With total flux
density at least 1 Jy and declination above -40 degree, we found 37 suitable
new targets. It is a nearly 25% addition to the known mm-VLBI sources. Such
objects are also potentially useful as phase-reference calibrators for the
future Japanese SVLBI mission ASTRO-G at its highest observing frequency (43
GHz). The phase-referencing capability of ASTRO-G would allow long integrations
and hence better sensitivity for observing faint target sources close to
suitable phase calibrators in the sky
4C 02.27: what is inside a double-double radio quasar?
Recently Jamrozy et al. (2009) identified 4C 02.27 (J0935+0204) as the first
possible example of a double-double radio source which is optically identified
with a quasar (i.e. not a galaxy), at the redshift of z=0.649. The overall
projected angular size of the radio source reaches about 1.5', with a prominent
"core" component in the centre. The two opposite pairs of radio lobes might
indicate two periods of episodic activity. We report on our short exploratory
1.6-GHz Very Long Baseline Interferometry (VLBI) observations of the innermost
radio structure of the quasar, conducted with the electronic European VLBI
Network (e-EVN) on 2009 September 30. These revealed a milliarcsecond-scale
compact source which is the base of the approaching one of the two symmetric
relativistic jets currently supplying the hot spots in the inner pair of the
arcsecond-scale radio lobes in 4C 02.27.Comment: 4 pages, 2 figures, to appear in the proceedings of the 10th European

Tullock Challenges: happiness, revolutions and democracy
Gordon Tullock has been one of the most important founders and contributors to Public Choice. Two innovations are typical âTullock Challengesâ. The first relates to method: the measurement of subjective well-being, or happiness. The second relates to digital social networks such as Facebook, Twitter, or to some extent Google. Both innovations lead to strong incentives by the governments to manipulate the policy consequences. In general âWhat is important, will be manipulated by the governmentâ. To restrain government manipulation one has to turn to Constitutional Economics and increase the possibilities for direct popular participation and federalism, or introduce random mechanisms.Happiness, social networks, constitutional economics, random mechanisms, public choice
Overprotected Politicians
This paper argues that politicians are overprotected. The costs of political assassination differ systematically depending on whether a private or a public point of view is taken. A politician attributes a very high (if not infinite) cost to his or her survival. The social cost of political assassination is much smaller as politicians are replaceable. Conversely, the private cost of the security measures is low for politicians, its bulk â including time loss and inconvenience â is imposed on taxpayers and the general public. The extent of overprotection is larger in dictatorial than in democratic countries.
A Multiplicity of Approaches to Institutional Analysis. Applications to the Government and the Arts
Four types of âeconomicsâ relevant for institutional analysis are distinguished: Standard Neoclassical Economics; Socio-Economics or Social Economics; New Institutional Economics; and Psychological Economics (often misleadingly called Behavioural Economics). The paper argues that an extension of Neoclassical Economics with elements from other social sciences (including political science, sociology, psychology, law and anthropology) is fruitful to explain institutions because it allows us to maintain the strength of that approach. Social Economics can play an important role helping to overcome the limitations of Neoclassics. However, it should become more concrete, integrate what is useful in Neoclassics, and should seriously engage in empirical research.Institutional Economics, Neoclassics, Psychological Economics, Behavioural Economics, institutions

Knight Fever â Towards an Economics of Awards
Awards in the form of orders, medals, decorations and titles are ubiquitous in monarchies and republics, private organizations, not-for-profit and profit-oriented firms. Nevertheless, economists have disregarded this kind of non-material extrinsic incentive.The demand for awards relies on an individualâs desire for distinction, and the supply of awards on the provision of incentives. Relative price and income effects are shown to be identifiable and strong. A number of empirically testable propositions are formulated. As awards are (at least so far) impossible to measure adequately, empirical tests are carried out using the technique of analytic narrativesincentives, motivation, awards, orders, distinction, principal-agent
