In the setting of a dynamic general equilibrium model we ask the following question: What happens if the interest rate is settled exogenously in a level that differs from the one which emerges from equilibria in the markets? Although the subject of the setting of the interest rate by an external...

Rietz (1988) and Barro (2006) subject consumption and dividends to rare disasters in the growth rate. We extend their framework and subject consumption and dividends to rare disasters in the growth persistence. Wemodel growth persistence by means of two hidden types of economic slowdowns:...

We explore the optimal fertility age-pattern in a four-period OLG economy with physical capital accumulation. For that purpose, we firstly compare the dynamics of two closed economies, Early and Late Islands, which differ only in the timing of births. On Early Island, children are born from...

We explore empirically models of aggregate fluctuations in which consumers form anticipations about the future based on noisy sources of information and these anticipations affect output in the short run. Our objective is to separate fluctuations due to changes in fundamentals (news) from those...

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...
