Organic and tight

J. Cummings, M. Foreman, E. Schimmerling
2009 Annals of Pure and Applied Logic  
Say π : L κ ω+1 X and, for every n ≤ ω, π(κ n ) = ℵ n . Let Q = ult(M κω , π, ℵ ω ). Then X is organic ⇐⇒ Q is wellfounded and X is tight ⇐⇒ M κ ω+1 = M κω .  ...  In spite of what seems like progress, we have not answered the basic question of how mutual, organic and tight stationarity are related in L.  ...

Putting on a tight leash and levelling playing field: An experiment in strategic obfuscation and consumer protection

Yiquan Gu, Tobias Wenzel
2015 International Journal of Industrial Organization  
We find that policies that limit the effectiveness of obfuscation and policies that promote parity between firms can lead less prominent firms to increase their obfuscation efforts.  ...  In such a framework, we study the effects of two common policy measures: policies that directly protect consumers by hampering the effectiveness of obfuscation (Putting on a Tight Leash) 2 and policies  ...  markets where a number of reasons have been identified including cognitive limitations (Calvet et al., 2009) , behavioural biases (Stango and Zinman, 2009 ) and insufficient knowledge (Lusardi and  ...
