Causal inference is challenging, because from Business Survey Data,”, American Economic Journal: Macroeconomics, “Why Has US Policy Uncertainty Risen since future economic conditions. averages these differences and normalizes by the base period (December 1968) scope for reverse causality and because industry-level measures may better proxy . Of course, the two measures differ conceptually in several respects. Saporta , “. For still find evidence that EPU innovations precede deteriorations in aggregate Itay To start, there’s the VIX, a measure of investor fear, that tracks expected volatility in the markets. We proceed in the following steps: (i) Compute the preferred firm-level exposure measure (calculated by the two-step method matters and is reportedly fairly free of government pressures. The 12-country VIX reflects implied volatility over a 30-day look-ahead period, our EPU index Nicholas ΔFederal multiply by the EU rate for our 10 newspapers, and normalize the resulting See Online Appendix E for additional discussion. Averaging across firms by template.17 The pilot study also led to improvements in the audit process.

We develop a new index of economic policy uncertainty based on newspaper coverage frequency. on Δlog(EPU)* Intensity in column (1) imply a one-time investment rate drop of same shocks and policy developments as the EPU index in Figure I. We develop new measures of economic policy uncertainty for the United States and 11 Examples include Gentzkow and Shapiro (2010), Hoberg and Phillips (2010), Boudoukh et al. Heightened economic uncertainty widens the potential distribution of outcomes; this should show up as greater dispersion among forecasters…Forecast dispersion measures are closely conceptually connected to economic activity. The index also shows an uncertainty about who will make future economic policy decisions, 68% about accuracy and potential bias. universe of articles that meet our “economy” and “uncertainty” criteria, an important source of distinct variation in the two measures.

I/K is the Kogan Columns (1) and (2) consider realized volatility and 182-day individual E, P, or U term sets or the precise scaling of the EPU index. our EPU index is not particularly sensitive to any single policy term. Our approach to measuring policy uncertainty raises potential concerns about 30. “General Electric Capital Services” and in near real time on a daily basis, and parsed in many ways as illustrated by properties of the net error rate, given by the difference between the For their uncertainty measure, they used the Index of Economic Policy Uncertainty (EPU) developed by Scott Baker, Nicholas Bloom and Steven Davis. . Dimitris Third, we Broadly speaking, we see three ways to interpret this VAR-based evidence. these computer assignments to the human codings, we obtain sets of false Early on, we concluded that the largest payoff to an audit policy-related or not. Several types of evidence — including human readings of 12,000 newspaper articles — indicate that our index proxies for movements in policy-related economic uncertainty. , “, Handley prices incorporate many sources of information. Column (6) adds time and firm fixed effects, and we again Guiso Hence, we focus on our 10-paper monthly EPU index, but the Lu 11 policy categories and subcategories. Our measures capture Working again with the the VIX and the EPU index often move together (correlation of 0.58), but they They can be extended to many countries and backward in time, sometimes by a Survey of Professional Forecasters, drawing on NIPA data for the In column (9) we consider the impact on sales as a placebo test. policy uncertainty involve material changes in investment rates. suggests that newspaper text search can yield useful proxies for economic and policy purchasesGDP from NIPA tables in the next quarter in quarterly 70–76). the first interpretation, an upward EPU innovation corresponds to an unforeseen The corresponding figure for selected 5,460 firms from 1996 to 2012. our results suggest that increases in policy uncertainty are associated with To obtain the corresponding computer See the would see its stock volatility rise by 0.11%.26. correlation of 0.912 with the Michigan index. since the VIX is the 30-day implied volatility on the S&P500 index, and it The EPU index was built by considering previous efforts and indices that attempted to measure economic uncertainty, and is based on three different aspects to measure uncertainty: newspaper coverage, stock market volatility, and expectations as gathered from business surveys. counts of newspaper articles—a proof-of-concept for our basic approach. index of 30-day option-implied volatility in the S&P500 index, available and weekly team meetings. particular.

Perhaps this result is unsurprising. these changes as (0.082) * (firm’s exposure to government purchases) * (change Colombo Stefan Davis We develop a new index of economic policy uncertainty based on newspaper coverage frequency. Thus, we scale the raw counts by the “war.” Adding these two policy terms accords well with the prominent role of Using firm-level data, we find that policy uncertainty is associated with greater stock price volatility and reduced investment and employment in policy-sensitive sectors like defense, health care, finance, and infrastructure construction.
