In a simple continuous-time model where the learning process affects the willingness to hold liquidity, we provide an intuitive explanation of business cycle asymmetry and post-crisis slow recovery. When observing a liquidity shock, individuals rationally increase their subjective probability of...

In this paper, we first provide a brief exposition of the simplest version of the selfish life cycle model or hypothesis, which is undoubtedly the most widely used theoretical model of household behavior in economics, and then survey the literature on household saving behavior in Japan (with...

We study a model of behavior-based price discrimination where firms can agree to share customer information that can be used for personalized pricing. We show that firms are better off sharing customer information as it softens up-front competition when they gather information, consumers are...

Previous studies have stressed that inflation dynamics exhibit a substantial dispersion across sectors. Using US producer price data, we present evidence that sectoral inflation persistence is negatively correlated with market concentration, which is difficult to reconcile with the prediction of...

Abstract: In this paper, we consider statistical inference for high-dimensional approximate factor models. We posit a weak factor structure, in which the factor loading matrix can be sparse and the signal eigenvalues may diverge more slowly than the cross-sectional dimension, N. We propose a...

Pecuniary externalities in models with financial friction justify macroprudential policies for preventing economic agents' excessive risk taking. We extend the Diamond and Rajan (2012) model of banks with the production factors and explore how a pecuniary externality affects a bank's leverage....

We study a two-period model of behavior-based price discrimination in Fudenberg and Tirole (2000) but allow firms to make product choice in the first period. We show that the only possible equilibrium involves maximal differentiation. This is in contrast to Choe et al. (2018) where equilibrium...

To explore the propagation of undesirable policies in a form of populist extremism, we construct a social learning model featuring agency problems. Politicians in different countries sequentially implement a policy. Voters learn the incumbent politician's type and the desirable policy by...

To examine the effect of monetary policy on economic growth, we formulate an endogenous growth model with cash-in-advance constraints on R&D and capital accumulation as endogenous growth engines. Within this framework, we show that the relationship between economic growth and the nominal...

When a government considers a subsidy for an underdeveloped region, it has several options: the subsidies can be for land, wages, employment, or production. While land subsidy is a lump-sum transfer, the others are meant to promote local production or worker immigration. Under full employment,...
