Firm Data on AI
We present the first representative international data on firm-level AI use. We survey almost 6,000 CFOs, CEOs, and executives from stratified firm samples across the US, UK, Germany, and Australia. We find four key facts. First, around 70 percent of firms actively use AI, particularly younger, more productive firms. Second, while over two-thirds of top executives regularly use AI, their average use is only 1.5 hours a week, with one quarter reporting no AI use. Third, firms report little impact of AI over the last three years, with more than 80 percent of firms reporting no impact on either ...

Is It Time to Reassess the Focal Role of Core PCE Inflation?
In this paper, I review the history of “core” PCE inflation and its rationale: remove volatile items with transitory shocks to better highlight the trend in inflation. Structural changes in the inflation process imply that, on a “reducing volatility” basis, the list of items excluded from the “core” inflation basket (aside from gasoline) is far from optimal. This is true whether one assesses volatility on the basis of a weighted component monthly, or an index monthly, or a 12-month index, or a 5-year index. In addition, I demonstrate other deficiencies of exclusion indexes. ...

Monetary Policy and Real Exchange Rate Dynamics in Sticky-Price Models
We study how real exchange rate dynamics are affected by monetary policy in dynamic, stochastic, general equilibrium, sticky-price models. Our analytical and quantitative results show that the source of interest rate persistence ? policy inertia or persistent policy shocks ? is key. When the monetary policy rule has a strong interest rate smoothing component, these models fail to generate high real exchange rate persistence in response to monetary shocks, as policy inertia hampers their ability to generate a hump-shaped response to such shocks. Moreover, in the presence of persistent monetary ...

Current Account Dynamics and Monetary Policy
We explore the implications of current account adjustment for monetary policy within a simple two country DSGE model. Our framework nests Obstfeld and Rogoff's (2005) static model of exchange rate responsiveness to current account reversals. It extends this approach by endogenizing the dynamic adjustment path and by incorporating production and nominal price rigidities in order to study the role of monetary policy. We consider two different adjustment scenarios. The first is a "slow burn"where the adjustment of the current account deficit of the home country is smooth and slow. The second is ...

The Macroeconomic Effects of Cash Transfers: Evidence from Brazil
This paper provides new evidence on the macroeconomic impact of cash transfers in developing countries. Using a Bartik-style identification strategy, the paper documents that Brazil’s Bolsa Familia transfer program leads to a large and persistent increase in relative state-level GDP, formal employment, and informal employment. A state receiving 1% of GDP in extra transfers grows 2.2% faster in the first year, with R$100,000 of extra transfers generating five formal-equivalent jobs, half of which are informal. Consistent with a demand-side mechanism, the effects are concentrated in ...

Taxes and the Fed : Theory and Evidence from Equities
We provide a critical theoretical and empirical analysis that suggests a key driver of fiscal effects on equity markets is the Federal Reserve. For the Post-1980 era, tax cuts lead to higher cash flow news and higher discount rates. The discount rate news tends to dominate such that tax cuts are associated with lower equity returns. This result is flipped for the Pre-1980 era. Our results are confirmed across multiple measures of tax shocks (narrative, SVAR, municipal bonds, etc.) at different frequencies (daily, quarterly, annual). We motivate our empirical findings with a standard New ...

Gross Migration, Housing and Urban Population Dynamics
Cities experience significant, near random walk productivity shocks, yet population is slow to adjust. In practise local population changes are dominated by variation in net migration, and we argue that understanding gross migration is essential to quantify how net migration may slow population adjustments. Housing is also a natural candidate for slowing population adjustments because it is difficult to move, costly to build quickly, and a large durable stock makes a city attractive to potential migrants. We quantify the influence of migration and housing on urban population dynamics using a ...

The limits of forward guidance
The viability of forward guidance as a monetary policy tool depends on the horizon over which it can be communicated and its influence on expectations over that horizon. We develop and estimate a model of imperfect central bank communications and use it to measure how effectively the Fed has managed expectations about future interest rates and the influence of its communications on macroeconomic outcomes. Standard models assume central banks have perfect control over expectations about the policy rate up to an arbitrarily long horizon and this is the source of the so-called ?forward guidance ...

The Impact of Health and Economic Policies on the Spread of COVID-19 and Economic Activity
This paper empirically investigates the causal linkages between COVID-19 spread, government health containment and economic support policies, and economic activity in the U.S. up to the introduction of vaccines in early 2021. We model their joint dynamics as generated by a structural vector autoregression and estimate it using U.S. state-level data. We identify structural shocks to the variables by making assumptions on their short-run relation consistent with salient epidemiological and economic features of COVID-19. We isolate the direct impact of COVID-19 spread and policy responses on ...

The Impact of Health and Economic Policies on the Spread of COVID-19 and Economic Activity
This paper empirically investigates the causal linkages between COVID-19 spread, government health containment and economic support policies, and economic activity during 2020 in the U.S. We model their joint dynamics as generated by a structural vector autoregression and estimate it using U.S. state-level data. We identify structural shocks to the variables by making assumptions on their short-run relation consistent with salient epidemiological and economic features of COVID-19. We isolate the direct impact of COVID-19 spread and policy responses on economic activity by controlling for ...
