Growth Collapses

We study episodes where economic growth decelerates to negative rates. While the majority of these episodes are of short duration, a substantial fraction last for a longer period of time than can be explained as the result of businesscycle dynamics. The duration, depth and associated output loss of these episodes differs dramatically across regions. We investigate the factors associated with th...

Defining Conditional Independence Using Collapses

Trace semantics is extended to allow conditional commutativity among operations. Conditional commutativity is obtained by identifying the context (the set of global states) in which operations are commutative using special predicates. These will allow collapsing execution histories into equivalence classes of conditional traces. Using this approach, it is possible that the execution of two oper...

Silver type theorems for collapses

The classical theorem of Silver states that GCH cannot break for the first time over a singular cardinal of uncountable cofinality. On the other hand it is easy to obtain a situation where GCH breaks on a club below a singular cardinal κ of an uncountable cofinality but 2 = κ. We would like here to investigate the situation once blowing up power of singular cardinals is replaced by collapses of...
