Financial repression can be used to avoid a government default when fiscal policy is constrained. We present a model showing that optimal financial repression progresses through successive stages with increasing levels of distortion. Data from advanced economies suggest that the initial stage of...

This paper presents a tractable model of a global economy in which countries can use a broad range of policy instruments---the nominal interest rate, taxes on imports and exports, taxes on capital flows or foreign exchange interventions. Low demand may lead to unemployment because of downward...

We study the interplay of optimal ex-ante (macroprudential) and ex-post (monetary or fiscal stimulus) measures to respond to systemic financial crises in a tractable model of fire sales. We find that it is generally optimal to use both, rejecting the Greenspan doctrine to only intervene ex post....

We study a dynamic model in which the interaction between debt accumulation and asset prices magnifies credit booms and busts. We find that borrowers do not internalize these feedback effects and therefore suffer from excessively large booms and busts in both credit flows and asset prices. We...

This paper analyzes prudential controls on capital flows to emerging markets from the perspective of a Pigouvian tax that addresses externalities associated with the deleveraging cycle. It presents a model in which restricting capital inflows during boom times reduces the potential outflows...

Standard theoretical arguments tell us that countries with relatively little capital benefit from financial integration as foreign capital flows in and speeds up the process of convergence. We show in a calibrated neoclassical model that conventionally measured welfare gains from this type of...

According to the consensus view in growth and development economics, cross country differences in per-capita income largely reflect differences in countries' total factor productivity. We argue that this view has powerful implications for patterns of capital flows: everything else equal,...

In theory, we should expect tariffs to be partially offset by a currency appreciation in the tariff-imposing country or by a depreciation in the country on which the tariff is imposed. We find, based on a calibrated model, that the tariffs imposed by the US in 2018-19 should not have had a large...

We use a tractable model to show that emerging markets can protect themselves from the global financial cycle by expanding (rather than restricting) capital flows. This involves accumulating reserves when global liquidity is high to buy back domestic assets at a discount when global financial...

Economics and ethics both offer important perspectives on our society, but they do so from two different viewpoints - the central focus of economics is how the price system in our economy values resources; the central focus of ethics is the moral evaluation of actions in our society. The rise of...
