I analyze the recent experience of unconventional monetary policy in Sweden to study the interest rate transmission mechanisms of government bond purchases when interest rates are not constrained by a lower bound. Using dynamic term structure models and event study regressions I find that...

We analyze optimal monetary policy and its implications for asset prices, when aggregate demand has inertia and responds to asset prices with a lag. If there is a negative output gap, the central bank optimally overshoots aggregate asset prices (asset prices are initially pushed above their...

We study what makes government bonds a safe asset. Building on a sample of monthly changes in government bond yields in 40 advanced and emerging countries, we analyse the sensitivity of yields to country specific fundamentals interacted with changes in global risk (VIX). We find that inertia...

Recent data show substantial increases in the size of gross external asset and liabilitypositions. The implications of these developments for optimal conduct of monetarypolicy are analyzed in a standard open economy model which is augmented to allowfor endogenous portfolio choice. The model...

This paper presents a portfolio model of asset price effects arising from large-scale asset purchases by central banks — commonly known as quantitative easing (QE). Two financial frictions, segmentation of the market for central bank reserves and imperfect asset substitutability, give rise to...

We study the role of firm heterogeneity in affecting business cycle dynamics and optimal stabilization policy. Firms differ in their degree of cyclicality, and hence, exposure to aggregate risk, leading to firm-specific risk premia that influence resource allocations. The heterogeneous firm...
