Abstract: Uncertainty shocks deliver a source of fundamentally driven systemic banking crises. A literature on financial cycles has shown an expansion in the bank lending often presages a systemic crisis by making the financial sector more fragile. I show an increase in realised volatility exacerbates fragility making the financial sector more susceptible to a crisis. Under conditions of elevated volatility which characterize crisis years, the probability of a systemic crisis increases by a factor of 12.07 times, compared to non-crisis years. In a dynamic model featuring self-fulfilling debt crises heightened uncertainty increases the probability of banker’s expected insolvency at fire-sale prices and leading to an increase in the likelihood of a run by liability holders.

Abstract: We introduce a multisector New Keynesian model with heterogeneous households, segmented sectoral labor markets and a production network to study the transmission channels of sector-specific government expenditures on the economy. The model features an intersectoral Keynesian cross from which we derive a MPC-augmented network multiplier. We formulate analytically how the network structure determines spillover and cascade effects via intersectoral linkages and sectoral spending propensities. We argue that the interaction of the Keynesian spending multiplier and the network multiplier displays a novel mechanism which is important for the understanding of the propagation of sectoral demand shocks. Sector-specific fiscal policy is particularly strong when a large fraction of high-MPC households is employed in labor-intensive and downstream sectors. Using household balance sheet data, we show that there are substantial and persistent divergences in household portfolios and in the proportion of hand-to-mouth households between sectors. When calibrating our model to the U.S. economy, we find sizable differences in sectoral government spending multipliers and distributional effects.

Abstract: I study the responses of macroeconomic aggregates to an international asset demand shock. The identified shock produces volatile exchange rate dynamics and fluctuations in consumption, investment and output where it explains 33%, 49% and 53% of the 5 year forecast error variance, respectively, when estimated using USA and EU data from 1996 to 2021. I interpret the volatility of macro aggregates to the shock as inconsistent with Itskhoki and Mukhin (2021)’s theory of exchange rate disconnect which claims such a shock should be unrelated to macroeconomic variables aside from the exchange rate to explain exchange rate puzzles. In particular, I find the result is driven by the correlation between shifts in home (EU) household’s demand for dollar denominated bonds and USA and EU productivity. This paper’s empirical findings are evidence for the relationship between financial shocks and the supply side of the economy.
