Discount rates affect stock prices directly via the discount-rate channel or indirectly via the cash-flow channel because expected future cash-flow growth varies with the discount rates. The traditional Macaulay duration captures the effect from the discount-rate channel. I propose a novel...

This paper presents a model comparing the optimal degree of asset class diversification abroad by a central bank and a sovereign wealth fund. We show that if the central bank manages its foreign asset holdings in order to meet balance of payments needs, particularly in reducing the probability...

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...

This paper explores the impacts on an economy of a central bank changing the size and composition of its balance sheet. One of the ways in which such asset purchases could influence prices and demand is via portfolio balance effects. We develop and calibrate a simple OLG model in which...

This paper presents statistical analysis supporting stylized facts about sovereign wealth funds (SWFs). It discusses the forces leading to the growth of SWFs, including the role of fuel exports and ongoing current account surpluses, and large hoarding of international reserves. It analyzes the...
