We propose and estimate a quantitative model of exchange rates in which the participants in the FX market are intermediaries subject to value-at-risk (VaR) constraints. The model resolves the exchange rate puzzles (Backus-Smith, forward premium, volatility, CIP deviation) and generates new implications consistent with the data.

Measures of U.S. government policy approval are strongly related to persistent fluctuations in the dollar exchange rates. Contemporaneous correlations reach 50%. High approval ratings further forecast a decline in the dollar risk premium, a persistent increase in economic growth, and a reduction in future economic volatility. We provide an illustrative economic model to interpret our empirical evidence.

Higher debt-to-GDP ratios (i) predict higher excess stock returns with 30% five-year out-of-sample R-squared, (ii) correlate with higher corporate bond excess returns and credit spreads, (iii) are associated with lower real risk-free rates and government debt expected returns. I rationalize these findings in a general equilibrium model featuring time-varying fiscal uncertainty.

We show the significance of output volatility (vol) shocks for both currency and international quantity dynamics: (1) consumption and output vols are imperfectly correlated within countries; (2) across countries, consumption vol is more correlated than output vol; (3) the pass-through of relative output vol shocks onto relative consumption vol is significant, especially for small countries; and (4) the consumption differentials vol and exchange rate vol are disconnected. We rationalize these findings in a frictionless model with multiple goods and recursive preferences featuring a novel and rich risk sharing of vol shocks.

We empirically document and theoretically evaluate a dual role for government debt. An increase in government debt improves liquidity and lowers liquidity premia, while it creates policy uncertainty and raises default risk premia. We interpret and quantitatively evaluate these two channels through the lens of a general equilibrium asset pricing model with risk-sensitive agents subject to liquidity shocks. The calibrated model generates quantitatively realistic liquidity spreads and default risk premia, and suggests that increasing safe asset supply can be risky.
