This paper investigates the optimal monetary policy response to a shock to collateral when policymakers act under discretion and face model uncertainty. The analysis is based on a New Keynesian model where banks supply loans to transaction constrained consumers. Our results confirm the...

We augment a standard monetary DSGE model to include a banking sector and financial markets. We fit the model to Euro Area and US data. We find that agency problems in financial contracts, liquidity constraints facing banks and shocks that alter the perception of market risk and hit financial...

Crises are triggered by the inherent uncertainty of the capitalist system. We represent this uncertainty in an open economy real business cycle model of the UK by including non-stationary productivity shocks. A random sequence of good or bad shocks will accumulate, producing euphorias and...

We examine the inter-linkages between financial factors and real economic activity. We review the main theoretical approaches that allow financial frictions to be embedded into general equilibrium models. We outline, from a policy perspective, the most recent empirical papers focusing on the...

In this paper, I use high-frequency financial market estimates to identify the monetary policy shock in a non-recursive 133 variable FAVAR. All restrictions are imposed exclusively on impact, and only on financial market variables. Using the economy's underlying factor structure as the link...

This paper studies the effects of three financial shocks in the economy: a net-worth shock, an uncertainty or risk shock, and a credit-spread shock. We argue that only the latter can push the nominal interest rate against its zero lower bound. Further, a recessionary shock to the net worth or...

We assess the effects of financial shocks on inflation, and to what extent financial shocks can account for the "missing disinflation" during the Great Recession. We apply a vector autoregressive model to US data and identify financial shocks through sign restrictions. Our main finding is that...

The role of bank capital as a propagation channel of shocks is strongly pronounced in recent macroeconomic models. In this paper, we show how the evolution of bank capital depends on the share of non-state-contingent assets in banks’ balance sheets and present the consequences for...

This paper empirically tests whether monetary policy can have a perverse effect on aggregate demand in emerging economies, because of short-term speculative inflows. For this purpose, a bayesian VAR is estimated on a panel of six major emerging countries. Monetary and risk shocks are identified...

This paper attempts to identify how monetary policy shocks affect stock prices by using Mundell and Fleming's theory of the "Impossible Trinity". According to this theory, it is impossible to simultaneously have a fixed exchange rate, free capital movement (an absence of capital controls), and...
