In a three player dynamic public goods experiment, social output today determines production possibilities tomorrow. In each period, players choose to sabotage, to co-operate, or to play best response. Sabotage harms social output and growth. Mutual co-operation maximises both. The property rights to social output are distributed unequally. Extent and skew of inequality are varied. Empirical st...

【キーワード】Sabotage; Tournament; Fast track; Late selection; Supermodularity; Submodularity 【要約】This paper examines a two-period tournament where agents may possibly engage in destructive sabotage activities. Under plausible circumstances, sabotage proves to be an effective tool for low-ability agents, especially when they are faced with high-ability agents. The possibility of sabotage then gives r...

Even before the Arab Spring, the resource-rich, rentier states of the Arabian Gulf had been described as some of the most stable regimes in the world. Their apparent robustness over the last few years has only reinforced this view, and led many to conclude that these regimes have eliminated any real threat to their rule. In the following paper, I challenge this conventional wisdom and explore t...

A study conducted by the U.S. Secret Service and the Carnegie Mellon University Software Engineering Institute CERT Program analyzed 150 insider cyber crimes across U.S. critical infrastructure sectors. Follow-up work by CERT involved detailed group modeling and analysis of 30 cases of insider IT sabotage out of the 150 total cases. Insider IT sabotage includes incidents in which the insider’s ...

Unethical behavior within organizations is not rare. We investigate experimentally the role of status-seeking behavior in sabotage and cheating activities aiming at improving one’s performance ranking in a flat-wage environment. We find that average effort is higher when individuals are informed about their relative performance. However, ranking feedback also favors disreputable behavior. Some ...

This paper explores the consequences of sabotage for the design of incentive contracts. The possibility of sabotage gives rise to a dynamic concern, similar to the Ratchet effect, which distorts the agents’ incentives. We first show that the mere possibility of sabotage may make it impossible to implement the first-best effort, and then offer two distinct incentive schemes, fast track and late ...

Contourlet is one of the new topics in image processing and video processing. Besides a lot of theoretical works about contourlet transform, its applications have roused enough interest as a critical means of multi-scale geometric analysis. This article, focusing on camera sabotage detection, extends the application of contourlet transform to video processing. A new algorithm to detect camera s...
