Notes: US Presidential approval rate and advanced economy dollar index.
Measures of U.S. government policy approval, such as U.S. Presidential or Congressional ratings, are strongly related to persistent fluctuations in the dollar exchange rates. Contemporaneous correlations between approval ratings and the dollar value reach 50% against the advanced economy currencies, in real and nominal terms, in levels and multi-year changes. 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 several years in the future. We provide an illustrative economic model to interpret our empirical evidence. In the model, policy valuations are forward-looking and reflect net contributions of policy to economic growth. Policy valuations (approvals) increase at times of high policy-related growth and low policy-related uncertainty, which are the times of a strong dollar and low dollar risk premium.

Notes: Circular flow in a model where the major participants in the international financial market are financial intermediaries.
We study exchange rate determination through ﬁnancial intermediaries. We propose a model in which the participants in the FX market are intermediaries subject to value-at-risk
constraints. Higher volatility translates into tighter leverage constraints. Therefore, intermediaries require higher returns to hold foreign assets and the foreign currency is expected to
appreciate. Estimated by the simulated method of moments, our model quantitatively resolves the Backus-Smith puzzle, the forward premium puzzle, and the exchange rate volatility puzzle and explains deviations from covered interest rate parity. The model generates new implications for exchange rates and capital ﬂows consistent with the data.

Notes: 5-year subsequent excess return, and its projection on debt-to-GDP ratio and fiscal uncertainty.
I document that higher debt-to-GDP ratio: (i) predicts higher excess stock returns with 30% five-year out-of-sample R-squared; (ii) correlates with higher credit risk premia in corporate bond excess returns and yield spreads; (iii) is associated with lower real risk-free rates and expected returns on government debt; and (iv) comoves with higher fiscal policy uncertainty. I rationalize these facts in a model featuring distortionary taxation and time-varying fiscal uncertainty. The tax risk premium is sizable and varies with fiscal uncertainty, which is endogenously linked to the debt-to-GDP ratio. Fiscal uncertainty increases debt valuation, and conversely debt raises uncertainty in fiscal consolidations.

Notes: Relative responses of the volatility and growth rate of output (y), consumption (c), the change of net-export-to-output ratio (NX/Y), and the volatility of excess returns (rexd ) to an output volatility shock in the foreign country relative to the US.

We show novel empirical evidence on the significance of output volatility (vol) shocks for both currency and international quantity dynamics. Focusing on G-17 countries, we document that (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.

Notes: Impulse responses of to a shock to debt-to-GDP ratio.
US government bonds exhibit many characteristics often attributed to safe assets: They are very liquid and lenders readily accept them as collateral. Indeed, a growing literature documents significant convenience yields, perhaps due to liquidity, in scarce US Treasuries, suggesting that rising Treasury supply and government debt comes with a declining liquidity premium and a fall in firms' relative cost of debt financing. In this paper, we empirically document and theoretically evaluate a dual role for government debt. Through a liquidity channel an increase in government debt improves liquidity and lowers liquidity premia by facilitating debt rollover, thereby reducing credit spreads. Through an uncertainty channel, however, rising government debt creates policy uncertainty, raising 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, in which firms issue defaultable bonds and the government issues tax-financed bonds that endogenously enjoy liquidity benefits. The calibrated model generates quantitatively realistic liquidity spreads and default risk premia, and suggests that while rising government debt reduces liquidity premia, it not only crowds out corporate debt financing, and therefore, investment, but also creates uncertainty reflected in endogenous tax volatility, credit spreads, and risk premia, and ultimately consumption volatility. Therefore, increasing safe asset supply can be risky.
