This paper develops a model where firms' equilibrium capital structures depend on firms' risk characteristics and investors' aggregate risk appetite. I assume that the law of one price fails because security markets are incomplete and risk-sharing through short-selling or borrowing is limited....

We use supervised machine learning to approximate the expectations typically contained in the optimality conditions of an economic model in the spirit of the parameterized expectations algorithm (PEA) with stochastic simulation. When the set of state variables is generated by a stochastic...

In this paper, we examine an exchange economy with a financial market composed of three assets: a share of a stock, an European call option written on the stock, and a riskless bond.

We consider an incomplete but frictionless financial market in which non-redundant forward contracts contribute to span the uncertainty present in the economy. When such forward contracts are available for trade, some standard results of portfolio and dynamic asset pricing theory must be...

When forward contracts are involved in dynamic portfolio strategies, incurred profits or losses that accrue at each instant are locked-in in the forward position up to the contract maturities. The discounted value of these gains or losses at each date t is part of investors’ wealth. This...

We formalize the idea that the financial sector can be a source of non-fundamental risk. Households' desire to hedge against price volatility can generate price volatility in equilibrium, even absent fundamental risk. Fearing that asset prices may fall, risk-averse households demand safe assets...

This paper develops a simulation-based solution method to solve large state space macrofinance models using machine learning. We use a neural network (NN) to approximate the expectations in the optimality conditions in the spirit of the stochastic parameterized expectations algorithm (PEA)....

We formalize the idea that the financial sector can be a source of non-fundamental risk. Households' desire to hedge against price volatility can generate price volatility in equilibrium, even absent fundamental risk. Fearing that asset prices may fall, risk-averse households demand safe assets...

We propose a 2-country asset-pricing model where agents' preferences change endogenously as a function of the popularity of internationally traded goods. We determine the effect of the time-variation of preferences on equity markets, consumption and portfolio choices. When agents are more...

In this paper, we examine an exchange economy with a financial market composed of three assets: a share of a stock, an European call option written on the stock, and a riskless bond. The financial market is assumed to be incomplete and the option is not a redundant asset. In such a case the...
