We provide a production‐based asset pricing model with dispersed information and small deviations from full rational expectations. In the model, aggregate output and equity prices depend on the higher‐order beliefs about aggregate demand and individual stochastic discount factors. We prove...

This paper considers tax policies to deal with Sudden Stops – declines in aggregate activity that are magnified by a binding collateral constraint – that occasionally occur in emerging market economies. Households and/or the government are assumed to face model uncertainty and desire...

In this paper we examine how model uncertainty due to the preference for robustness (RB) affects optimal taxation and the evolution of debt in the Barro tax-smoothing model (1979). We first study how the government spending shocks are absorbed in the short run by varying taxes or through debt...

In this paper we study a two-sector production small open economy subject to a collateral constraint in which a financial crisis can arise endogenously and alternate with normal time periods. In this class of models, the scope for policy intervention arises because individual agents do not...

In this paper we examine the effects of two types of “induced uncertainty”, model uncertainty due to robustness (RB) and state uncertainty due to finite information–processing capacity (called rational inattention or RI), on consumption and the current account. We show that the combination...

type="main" xml:lang="en" <p>In this paper we examine the implications of two theories of informational frictions, signal extraction (SE) and rational inattention (RI), for optimal decisions and economic dynamics within the linear-quadratic-Gaussian (LQG) setting. We first show that if the variance...</p>

In this paper we examine the effects of model misspecification (robustness or RB) on international consumption correlations in an otherwise standard small open economy model with endogenous capital accumulation. We show that in the presence of capital mobility in financial markets, RB lowers the...
