We develop a novel instrumental variable to identify geopolitical oil price shocks arising around significant geopolitical tensions and examine their transmission to the global oil market, key U.S. macroeconomic aggregates, and cross-border spillover effects on other commodity markets, output,...

We study why inflation responds differently to economic activity over time. Using survey data covering the universe of Japanese firms, we show that firms are unable to perfectly distinguish aggregate from sector-specific demand changes, leading to positively correlated expectations about these...

We study how global supply chain disruptions affect monetary policy transmission. Post-pandemic evidence indicates surging transportation costs, goods-market imbalances, and rising prices. We develop a model in which logistical bottlenecks (upstream slack coexisting with downstream shortages)...

This paper studies the design of monetary policy in small open economies with domestic and cross-border production networks and nominal rigidities. The monetary policy that closes the domestic output gap is nearly optimal and is implemented by stabilizing the aggregate inflation index that...

We develop a simple model of financial intermediation with search and matching frictions between banks and firms. The model links credit market tightness -encapsulating the abundance of credit- to the search and opportunity costs of credit intermediation. Search costs generate lending to...

We employ Synthetic Control Method techniques to estimate the causal effect of Brexit on the consumer price index (CPI) in the United Kingdom. We construct a counterfactual CPI index from a weighted pool of comparable economies and find that the price level of the United Kingdom rose...

This paper extends prior research by introducing a novel econometric framework- Regime-Dependent Granger Causality-to analyse the systematic elements of United States (US) monetary policy. Employing vector autoregressive models allowing for temporary Granger causality, we examine the association...

Until recently literature on dynamic factor models invariably assumed that the cross sectional error covariance matrix is diagonal. This is due to the many parameters which need to be estimated for large data sets, which is known as the curse of dimensionality. Spencer (2024) introduced a novel...

This paper explores the impact of wartime military spending on postwar U.S. fiscal policy, with a particular focus on the "ratchet effect" in taxes and transfers. Through econometric analysis, we investigate how changes in defense spending during and after conflicts shape long-term federal...

This paper shows the importance of technological synergies among heterogeneous firms for aggregate fluctuations. First, we document six novel empirical facts using microdata that suggest the existence of important technological synergies between trading firms, the presence of positive...
