We discuss the relationship between various weak distributive laws and games in Boolean algebras. In the first part we give some game characterizations for certain forms of Prikry’s “hyper-weak distributive laws”, and in the second part we construct Suslin algebras in which neither player wins a certain hyper-weak distributivity game. We conclude that in the constructible universe L , all the d...

An attempt to introduce VAT in 1995 failed after widespread protests. Although a second attempt to introduce VAT in 1998 succeeded, strong resistance to tax reform remains, and the total tax base remains narrow and over-dependent on petroleum taxe...
