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...

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,...

We examine the effect of immigration on the host country in the dynamic model that can deal with secular unemployment. Immigration has contrasting effects, depending on the economic state of the host country. If there is unemployment, immigration worsens unemployment and decreases consumption by...

Using a dynamic optimization model of a monetary economy where persistent unemployment can prevail, we examine the effects of environmental policies on consumption and pollution emissions in a full-employment and a stagnant economy. If full employment prevails, environmental policies such as...

Previous studies have argued that output growth in advanced economies declined during the Great Recession and remained low afterward. This paper proposes a model to explain this slowdown in output growth. We incorporate wealth preferences and downward nominal wage rigidity into a standard...

In this paper, we show that underemployment and not necessarily high unemployment becomes the main measure of economic slack under secular stagnation. Specifically, persistent underemployment occurs in the search and matching model, provided that households derive utility from holding wealth,...

We consider a neoclassical economy where households derive utility from holding wealth. We show that, under some conditions, there can be rational bubbles. Hence, we provide a microfoundation for bubbles that relies on a frictionless infinite-horizon economy without any heterogeneity across...
