We consider the optimality of various institutional arrangements for agencies that conduct macro-prudential regulation and monetary policy. When a central bank is in charge of price and financial stability, a new time inconsistency problem may arise. Ex-ante, the central bank chooses the...

We study the effects of permanent and temporary income shocks on precautionary saving and investment in a "store-or-sow" model of growth. High volatility of permanent shocks results in high precautionary saving in the safe asset and low investment, or a "volatility trap." Namely, big savers...

We provide a systematic analysis of the properties of individual returns to wealth using twelve years ofpopulation data from Norway's administrative tax records. We document a number of novel results.First, during our sample period individuals earn markedly different average returns on their...

This paper studies the long-run relationship between consumption, asset wealth and income - the consumption-wealth ratio - in Germany, based on data from 1980 to 2003. Earlier papers for the Anglo-Saxon economies have documented that departures of these three variables from their common trend...

Motivated by the apparent failure of the credit multiplier mechanism (CM) to deliver amplification in DSGE models, we re-examine its role in business cycles to address the question: is something wrong with the CM? Our answer is no. In coming to this answer we construct a model with reproducible...

We argue that the U.S. personal saving rate's long stability (from the 1960s through the early 1980s), subsequent steady decline (1980s-2007), and recent substantial increase (2008-2011) can all be interpreted using a parsimonious ‘buffer stock' model of optimal consumption in the presence of...

In coming decades, China will undergo a notable demographic transformation, with its old-age dependency ratio doubling to 24 percent by 2030 and rising even more precipitously thereafter. This paper uses the permanent income hypothesis to reassess national savings behavior, with greater...

Inclusive growth, narrowly defined in this paper as growth that helps reduce inequality, is achieved if consumption of the poor increases faster than consumption of the rich. The paper presents a simple accounting framework for a per-percentile consumption diagnostics that could inform...

This paper studies the effect of two labor market institutions, unemployment insurance (UI) and job search assistance (JSA), on the output cost and welfare cost of recessions. The paper develops a tractable incomplete-market model with search unemployment, skill depreciation during unemployment,...

We study, both empirically and quantitatively, the role of savings and the labor supply inself-insurance channels over the life cycle when one faces not only idiosyncratic income risks, but also changes in longevity risk and pension benefits. We pick China as a case study since China has...
