This paper introduces a new model to capture the key stylized facts of firm price setting behavior in the open economy. At the firm level, producers adjust their domestic prices more frequently and fully in response to marginal cost shocks than for the same goods sold abroad. At the macro level, the terms of trade are less volatile than the real exchange rate and trade liberalization reduces ma...

We consider the compressible Kraichnan model of turbulent advection with small molecular diffusivity and velocity field regularized at short scales to mimic the effects of viscosity. As noted in [5], removing those two regularizations in two opposite orders for intermediate values of compressibility gives Lagrangian flows with quite different properties. Removing the viscous regularization befo...

We revisit the question whether the critical behavior of sandpile models with sticky grains is in the directed percolation universality class. Our earlier theoretical arguments in favor, supported by evidence from numerical simulations [ Phys. Rev. Lett., 89 (2002) 104303], have been disputed by Bonachela et al. [Phys. Rev. E 74 (2004) 050102] for sandpiles with no preferred direction. We discu...

Weakly-Sticky(WS) Datalog+/- is an expressive member of the family program classes that defined on basis conditions stickiness and weak-acyclicity. Conjunctive query answering (QA) over WS programs has been investigated, its tractability in data complexity established. However, design implementation practical QA algorithms their optimizations have open. In order to fill this gap, we first study...

This paper studies the aggregate dynamics of durable and nondurable consumption under sticky information diffusion (SID) due to noisy observations and slow learning within the permanent income framework. We show that SID can significantly improve the model’s predictions on the joint behavior of income, durable, and nondurable consumption at the aggregate level. Specifically, we find that SID ca...
