We develop a stylized two-sector business cycle model with endogenous firm dynamics in the investment goods sector. The positive correlation between firms' profitability and the relative price of investment goods generates an endogenous persistence mechanism in productivity dynamics which drives...

The publication of the book Capital in the Twenty-First Century by Piketty helped to increase the debate about the prospects of the evolution of income and wealth inequality in this century. One of the main controversies is about the effects to the income and wealth inequalities of a decrease in...

Why do advanced economies fall into prolonged periods of economic stagnation, particularly in the aftermath of credit booms? We present a model of persistent aggregate demand shortage based on strong liquidity preferences of households, in which we incorporate financial imperfections to study...

Disaster models are typically agnostic as to what spawns tail events, but are often calibrated on labor shocks. Using a novel way to construct rare event factors using the CEX survey data, I study whether the type of idiosyncratic shock modeled matters empirically. I estimate an augmented...

Satiation of need is generally ignored by growth theory. I study a model where consumers may be satiated in any given good but new goods may be introduced. A social planner will never elect a trajectory with long-run satiation. Instead, he will introduce enough new goods to avoid such a...

We examine a trivariate time series model that is subject to a regime switch, where the shifts are governed by an unobserved, two-state variable that follows a Markov process. The analysis is performed in a Bayesian framework developed by Albert and Chib (1993), where the unobserved states are...

This paper presents a simple Ramsey-type model example where two infinitely-living agents have same utility function except for time preference, and shows that equilibrium is indeterminate that is to be interpreted as being non-existent. The issues regarding New Keynesian transversality...

This paper studies attention allocation behavior of rationally inattentive consumers who have CRRA preferences, face uninsured capital income risk, and suffer from an information-processing capacity constraint. For given attention devoted to capital income risk, we solve for the optimal...

We present evidence that the mix of transitory and permanent shocks to consumption is changing over time. We study implications of this finding for asset prices. The uncovered dynamics of consumption implies modestly upward sloping real bond and equity curves, upward sloping nominal yield curve,...

Standard dynamic models of structural transformation, without knife-edge and counterfactual parameter values, preclude balanced growth path (BGP) analysis. This paper develops a dynamic equilibrium concept for a more general class of models | an alternative to a BGP, which we coin a Stable...
