The idea of an " alternating access " model (as it...

Transfers and Development Easy Come , Easy Go ?

Yet, building on the pioneering work by Thaler (1999) recent work by behavioural economists highlights that people code income in different mental accounts, creating a direct link between spending behaviour and income sources, thereby violating the fungibility assumption. This paper examines whether the marginal prop...

Easy Sets Without Easy Small Subsets

We show the existence of relativized worlds relative to which there exist innnite polynomial-time computable sets without innnite polynomial-time computable sparse subsets or even non-deterministically polynomial-time computable sparse subsets. This result is tight since every innnite P set has an innnite sparse coNP subset.

Getting in is easy, but how to get out?
