Is the standard hyperbolic-discounting model capable of robust qualitative predictions for savings behavior? Despite results suggesting a negative answer, we provide a positive one. We give conditions under which all Markov equilibria display either saving at all wealth levels or dissaving at...

We document in US data that returns to wealth across households are significantly heterogeneous, and persistently so. Motivated by this observation, we build a tractable general equilibrium model where households face persistent idiosyncratic returns to study the US wealth distribution. We show...

In this paper, we introduce our GDSGE framework and MATLAB toolbox for solving dynamic stochastic general equilibrium models with a novel global solution method. The framework encompasses many well-known incomplete markets models with highly nonlinear dynamics such as models on financial crises,...

Alternative assets are gaining increasing importance in investor's portfolios. One of their defining characteristic is their poor liquidity which often translates into an inherent smoothing process of the returns. For asset allocation purposes, this feature has to be seriously addressed as it...

The seminal contribution by Kiyotaki and Moore (1997) has spurred a vast literature on the importance of collateral constraints in propagating and amplifying shocks to the economy. However, most papers in the literature using collateral constraints assume non-state contingent debt, i.e., markets...

Band alignment between the organic and inorganic layers in two-dimensional (2D) hybrid perovskites inherently determines their carrier spatial confinement and charge separation, which is of great importance for optoelectronic applications. However, 2D perovskites usually exhibit type-I band...

Primary healthcare institutions (PHIs) in China have experienced a sizable decline in medical services in recent years. Despite the large regional disparities in China, there is a lack of evidence on the differential patterns of medical services offered by PHIs, especially from a spatial...

A nonlinear New Keynesian (NK) model with more severe downward rigidity in prices has a number of interesting implications. The “standard” NK equilibrium– with the nominal anchor during ELB episodes set by expectations about future monetary policy – exists even for long- lasting ELB...
