This paper provides a framework to endogenize rates of return for risk-free bonds and risky capital in an overlapping generation model. The rate of return on capital is endogenized by introducing idiosyncratic production shocks to avoid computation challenges associated with aggregate production...

This paper examines the consequences of international financial integration in a two-sector heterogeneous-agent dynamic general equilibrium model of occupational choice with financial constraints and idiosyncratic risks. We discuss the macroeconomic and distributional effects of financial market...

We construct a dynamic model economy in which investors from segmented markets have varying financial asset demands. Intermediaries make arbitrage profits by exploiting the price spreads across markets. Meanwhile, they are required to separately post collateral to support arbitrage trades. We...

This paper studies the effects that borrowing constraints have on savings and growth and argues that, though they increase savings, their effect on growth is ambiguous. Empirical evidence on the extent of borrowing constraints as well as savings, investment, human capital accumulation and growth...

This paper studies economies with complete markets where there is positive default on consumer debt. In a simple tractable two-period model, households can default partially, at a finite punishment cost, and competitive intermediaries price loans of different sizes separately. This environment...

In this paper, we build a heterogeneous agents-dynamic general equilibrium model wherein saving constraints interact with credit constraints. Saving constraints in the form of fixed costs to use the financial system lead households to seek informal saving instruments (cash) and result in lower...

This paper presents a new numerical method for solving stochastic general equilibrium models with dynamic portfolio choice over many financial assets. The method can be applied to models where there are heterogeneous agents, time-varying investment opportunity sets, and incomplete asset markets....

I build a small open economy (SOE) dynamic stochastic general equilibrium (DSGE) model to investigate the effect of a heterogeneous wage contract between regular and temporary workers on a macroeconomic volatility in a financially fragile economy. The imperfect financial market condition is...

In this paper I build a continuous time model of a complete financial market with $N$ heterogeneous agents whose constant relative risk aversion (CRRA) preferences differ in their level of risk aversion. I find that preference heterogeneity is able to replicate a high market price of risk and a...
