Since 2000s, large fluctuations in non-energy commodity prices have become a concern among policymakers about price stability. Using local projections, this paper investigates the effects of commodity price shocks on inflation. We estimate impulse responses of the consumer price indexes (CPIs)...

Using a simultaneous-move herding model of rational traders who infer other traders' private information on the value of an asset by observing their aggre- gate actions, this study seeks to explain the emergence of fat-tailed distributions of transaction volumes and asset returns in financial...

When individuals' labor and capital income are subject to uninsurable idiosyncratic risks, should capital and labor be taxed, and if so how? In a two period general equilibrium model with production, we derive a decomposition formula of the welfare effects of these taxes into insurance and...

This paper considers the macroeconomic effects of retailers' market concentra- tion and buyer-size discounts on inflation dynamics. During Japan's "lost decades," large retailers enhanced their market power, leading to increased exploitation of buyer-size discounts in procuring goods. We...

In this paper, we empirically investigate how real estate prices are affected by aging. We run regional panel regressions for Japan and the United States. Our regression re- sults show that, both in Japan and the U.S., real estate prices in a region are inversely correlated with the old age...

We construct a T¨ornqvist daily price index using Japanese point of sale (POS) scanner data spanning from 1988 to 2013. We find the following. First, the POS based inflation rate tends to be about 0.5 percentage points lower than the CPI inflation rate, although the difference between the two...

We study the impact that the liquidity crunch in 2008-2009 had on the U.S. economy’s growth trend. To this end, we propose a model featuring endogenous growth á la Romer and a liquidity friction á la Kiyotaki-Moore. A key finding in our study is that liquidity declined around the demise of...

I study a business cycle model where agents learn about the state of the economy by accumulating captal. During recessions, agents invest less, abd this generates noisier estimates of macroeconomic conditions and an increase in uncertainty. The endogenous increase in aggregate uncertainty...

This paper presents a tractable dynamic general equilibrium model of income and firm-size distributions. The size and value of firms result from idiosyncratic, firm-level productivity shocks. CEOs can invest in their own firms’ risky stocks or in risk-free assets, implying that the CEO’s...

In this paper, we investigate the structure and evolution of customer-supplier networks in Japan using a unique dataset that contains information on customer and supplier linkages for more than 500,000 incorporated non-financial firms for the five years from 2008 to 2012. We find, first, that...
