Measuring Price Inflation and Growth in Economic Well-Being with Income-Dependent Preferences
How can we accurately measure changes in living standards over time in the presence of price inflation? In this post, I discuss a novel and simple methodology that uses the cross-sectional relationship between income and household-level inflation to construct accurate measures of changes in living standards that account for the dependence of consumption preferences on income. Applying this method to data from the U.S. suggests potentially substantial mismeasurements in our available proxies of average growth in consumer welfare in the U.S.

No Credit, No Gain: Trade Liberalization Dynamics, Production Inputs, and Financial Development
We study the role of financial development on the aggregate and welfare implications of reducing import tariffs on capital and intermediate inputs. We document that financially underdeveloped economies feature a slower aggregate response following trade liberalization. We set up a quantitative general equilibrium model with heterogeneous firms subject to collateral constraints and estimate it to match salient features from Colombian plant-level data. Our model explains a substantial fraction of the differences in the empirical responses of GDP, consumption, and capital across economies with ...

No Credit, No Gain: Trade Liberalization Dynamics, Production Inputs, and Financial Development
We study the role of financial development on the aggregate and welfare implications of reducing trade barriers on imports of physical capital and intermediate inputs. We document that financially underdeveloped economies feature a slower response of real GDP, consumption, and investment following trade liberalization episodes that improve access to imported production inputs. To quantify the role of financial development, we set up a quantitative general equilibrium model with heterogeneous firms subject to financial constraints and estimate it to match salient features from Colombian ...

On the Distributional Effects of International Tariffs
What are the distributional consequences of tariffs? We build a trade model with incomplete asset markets and households that are heterogeneous in their income, wealth, and labor skill. We increase tariffs by 5 percentage points and examine several budget-neutral fiscal policies for redistributing tariff revenue. Without redistribution, tariffs hurt all households, but higher tradables prices disproportionately harm the poor and the ensuing decline in the skill premium disproportionately harms the skilled. With redistribution, lowering the labor income tax leads to lower economic activity but ...

On the Distributional Effects of International Tariffs
We provide a quantitative analysis of the distributional effects of the 2018 increase in tariffs by the U.S. and its major trading partners. We build a trade model with incomplete asset markets and households that are heterogeneous in their age, income, wealth and labor skill. When tariff revenues are used to reduce distortionary taxes on consumption, labor and capital income, the average welfare loss from the trade war is equivalent to a permanent 0.1 percent reduction in consumption. Much larger welfare losses are concentrated among retirees and low-wealth households, while only wealthy ...

Financial Development and Trade Liberalization
We study the role of financial development on the aggregate effects and welfare implications of reducing international trade barriers on production inputs such as physical capital and intermediates. We document that financially underdeveloped economies feature a slower response of real GDP, consumption, and investment following trade liberalization episodes that improve access to imported production inputs. We set up a quantitative general equilibrium model with heterogeneous firms subject to financial constraints and estimate it to match salient features from Colombian plant-level data. We ...

Capital controls: a normative analysis
Countries' concerns about the value of their currency have been studied and documented extensively in the literature. Capital controls can be?and often are?used as a tool to manage exchange rate fluctuations. This paper investigates whether countries can benefit from using such a tool. We develop a welfare-based analysis of whether (or, in fact, how) countries should tax international borrowing. Our results suggest that restricting international capital flows through the use of these taxes can be beneficial for individual countries, although it would limit cross-border pooling of risk. The ...

The redistributional consequences of tax reform under financial integration
I quantify the welfare effects of replacing the US capital income tax with higher labor income taxes under international financial integration using a two-country, heterogeneous-agent incomplete markets model calibrated to represent the US and the rest of the world. Short-run and long-run factor price dynamics are key: after the tax reform, interest rates rise less under financial openness than in autarky. Therefore, wealthy households gain less. Post-tax wages also fall less as a result of the faster capital accumulation, so the poor are hurt less. Hence, the distributional impacts of the ...

Optimal Capital Account Liberalization in China
China maintains tight controls over its capital account. Its current policy regime also features financial repression, under which banks are required to extend funds to state-owned enterprises (SOEs) at favorable terms, despite their lower productivity than private firms on average. We incorporate these features into a general equilibrium model. Our model illustrates a tradeoff between aggregate productivity and inter-temporal allocative efficiency from capital account liberalization under financial repression. As a result, along a transition path with a declining SOE share, ...

Eggs in One Basket: Security and Convenience of Digital Currencies
Digital currencies store balances in anonymous electronic addresses. We analyze the trade-offs between safety and convenience of aggregating balances in addresses, electronic wallets and banks. In our model agents balance the risk of theft of a large account with the cost to safeguarding a large number of passwords of many small accounts. Account custodians (banks, wallets and other payment service providers) have different objectives and tradeoffs on these dimensions; we analyze the welfare effects of differing industry structures and interdependencies, and in particular the consequences ...
