This paper studies a quantitative general equilibriummodel of the housing market where a large number of overlapping generations of homeowners face both idiosyncratic and aggregate risks but have limited opportunities to insure against these risks due to incomplete financial markets and...

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...

This paper studies risk premia in an incomplete-markets economy with households facing idiosyncratic consumption risk. If the dispersion of idiosyncratic risk varies over the business cycle and households have preference for early resolution of uncertainty, asset prices will be affected not only...

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...

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...

The distribution of asset holdings among US banks is increasingly concentrated toward a few large banks at the top. Concurrently, the household wealth inequality has increased. This paper provides a theoretical link between these empirical facts, by developing a novel quantitative general...

This paper presents an interpretation of post-1953 Colombian economic growth and a discussion on future outcomes. The interpretation takes the form of a data playback guided by the decentralized equilibrium version of the Cass-Koopmans-Ramsey model. The role of technical change as a driver of...

This paper aims at investigating whether or not a utilitarian social planner should subsidize longevity-enhancing expenditures in an economy with a PAYG pension system. For that purpose, a simple two-period OLG model is developed, in which the length of the second period of life can be raised by...

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...
