In the aftermath of the 1997-98 Asian crises, many emerging markets self-insured by accumulating international reserves (i.e., non-contingent assets) in excess of what many models predicted, while relying relatively little on state-contingent assets. This apparent over-reliance on self-insurance...

This paper uses barcode-level price data for 16 advanced and emerging market countries over the period 2005-2022 to investigate the role of individual firms and product categories in aggregate inflation. We decompose inflation into the component due to macroeconomic shocks and the granular...

This paper examines how liquidity shocks caused by currency shortages impact exports. We explore this in the context of India's 2016 currency demonetization, a sudden and unexpected policy announcement by the government that large-denomination currency notes--comprising 86% of the country's...

This article applies simple methods from computational linguistics to analyze unstructured corporate texts for economic surveillance. We apply text-as-data approaches to earnings conference call transcripts, patent texts, and job postings to uncover unique insights into how markets and firms...

We study the propagation of nominal shocks in a dispersed information economy where firms learn from and respond to information generated by their activities in product and factor markets. We prove the existence of a "Hayekian benchmark", defined by conditions under which imperfect information...

We provide a rationale for the observed pro-cyclicality of tax policies in emerging markets and present a novel mechanism through which tax policy amplifies the business cycle. Our explanation relies on two features of emerging markets: limited access to financial markets and limited commitment...

This paper considers VAR models incorporating many time series that interact through a few dynamic factors. Several econometric issues are addressed including estimation of the number of dynamic factors and tests for the factor restrictions imposed on the VAR. Structural VAR identification based...

This paper shows that the quantitative predictions of an equilibrium asset pricing model with financial frictions are consistent with the large consumption and current-account reversals and asset-price collapses observed in the "Sudden Stops" of emerging markets crises. Margin requirements set a...

The hypothesis that Sudden Stops to capital inflows in emerging economies may be caused by global capital market frictions, such as collateral constraints and trading costs, suggests that Sudden Stops could be prevented by offering price guarantees on the emerging-markets asset class. Providing...

One of the most serious problems that a central bank in an emerging market economy can face, is the sudden reversal of capital inflows. Hoarding international reserves can be used to smooth the impact of such reversals, but these reserves are seldom sufficient and always expensive to hold. In...
