Energy Efficiency and Fluctuations in CO2 Emissions

Staff Working Paper 2021-47 Soojin Jo, Lilia Karnizova
Carbon dioxide emissions have been commonly modelled as rising and falling with total output. Yet many factors, such as energy-efficiency improvements and shifts to cleaner energy, can break this relationship. We evaluate these factors using US data and find that changes in energy efficiency of consumption goods explain a significant proportion of emissions fluctuations. This finding also implies that models that omit energy efficiency likely overestimate the trade-off between environmental protection and economic performance.

Macroeconomic Uncertainty Through the Lens of Professional Forecasters

Staff Working Paper 2016-5 Soojin Jo, Rodrigo Sekkel
We analyze the evolution of macroeconomic uncertainty in the United States, based on the forecast errors of consensus survey forecasts of different economic indicators. Comprehensive information contained in the survey forecasts enables us to capture a real-time subjective measure of uncertainty in a simple framework.

Heterogeneity in the Dynamic Effects of Uncertainty on Investment

Staff Working Paper 2015-34 Sungje Byun, Soojin Jo
How does aggregate profit uncertainty influence investment activity at the firm level? We propose a parsimonious adaptation of a factor-autoregressive conditional heteroscedasticity model to exploit information in a subindustry sales panel for an efficient and tractable estimation of aggregate volatility.

Revisiting the Macroeconomic Impact of Oil Shocks in Asian Economies

Staff Working Paper 2015-23 Juncal Cunado, Soojin Jo, Fernando Perez de Gracia
This paper analyzes the macroeconomic impact of oil shocks in four of the largest oil-consuming Asian economies, using a structural vector autoregressive model. We identify three different types of oil shocks via sign restrictions: an oil supply shock, an oil demand shock driven by global economic activity and an oil-specific demand shock.

The Effects of Oil Price Uncertainty on the Macroeconomy

Staff Working Paper 2012-40 Soojin Jo
This paper investigates the effect of oil price uncertainty on real economic activity using a quarterly VAR with stochastic volatility in mean. Stochastic volatility allows oil price uncertainty to vary separately from changes in the level of oil prices, and thus the impact of oil price uncertainty can be examined in a more flexible yet tractable way.
