I analyze the implications of moral hazard in dynamic economy with production. In particular, I add agency frictions to a benchmark stochastic growth model, by assuming that firms observe output but hours worked and productivity are unobservable. I cast the problem as a continuous time principal...

In this paper we develop a theoretical model in order to understand comovements between asset returns and consumption over longer horizons. We develop an intertemporal general equilibrium model featuring two types of shocks: small, frequent and disembodied shocks to productivity and large...

We argue that emerging economies borrow short term due to the high risk premium charged by bondholders on long-term debt. First, we present a model where the debt maturity structure is the outcome of a risk sharing problem between the government and bondholders. By issuing long-term debt, the...

Expected exchange rate changes are determined by interest rate differentials across countries and risk premia, while unexpected changes are driven by innovations to macroeconomic variables, which are amplified by time-varying market prices of risk. In a model where short rates respond to the...

In this paper, I examine the implications of collateral constraints in a production economy and demonstrate that collateral constraints may have a role to play in resolving two outstanding puzzles: the risk-free rate puzzle and the total factor productivity puzzle. The first puzzle, as noted by...

This paper develops and estimates a macro-finance model that combines a canonical affine no-arbitrage finance specification of the term structure with standard macroeconomic aggregate relationships for output and inflation. From this new empirical formulation, we obtain several important...

In the aftermath of sovereign defaults and financial crises in the 1990s, there have been calls for the widespread use by sovereigns of equity-like financial instruments, in particular, of GDP-indexed bonds. This paper calibrates a general equilibrium model with endogenous default to a typical...
