How Persistent Are Unconventional Monetary Policy Effects?
This paper argues that one cannot precisely estimate the persistence of unconventional monetary policy (UMP) effects, especially with short samples and few observations. To make this point, we illustrate that the most influential model on the topic exhibits structural instability, and sensitivity to specification and outliers that render the conclusions unreliable. Restricted models that respect more plausible asset return predictability are more stable and imply that UMP shocks were persistent. Estimates of the dynamic effects of shocks should respect the limited predictability in asset ...

Breaks in the Phillips Curve: Evidence from Panel Data
We revisit time-variation in the Phillips curve, applying new Bayesian panel methods with breakpoints to US and European Union disaggregate data. Our approach allows us to accurately estimate both the number and timing of breaks in the Phillips curve. It further allows us to determine the existence of clusters of industries, cities, or countries whose Phillips curves display similar patterns of instability and to examine lead-lag patterns in how individual inflation series change. We find evidence of a marked flattening in the Phillips curves for US sectoral data and among EU countries, ...

Did the Federal Reserve Break the Phillips Curve? Theory and Evidence of Anchoring Inflation Expectations
In a macroeconomic model with drifting long-run inflation expectations, the anchoring of inflation expectations manifests in two testable predictions. First, expectations about inflation far in the future should no longer respond to news about current inflation. Second, better-anchored inflation expectations weaken the relationship between unemployment and inflation, flattening the reduced-form Phillips curve. We evaluate both predictions and find that communication of a numerical inflation objective better anchored inflation expectations in the United States but failed to anchor expectations ...

Why is the Hong Kong Housing Market Unaffordable? Some Stylized Facts and Estimations
The house price in Hong Kong is well-known to be "unaffordable." This paper argues that the commonly used house price-to-income ratio may be misleading in an economy with almost half of the population living in either public rental housing or subsidized ownership. Moreover, we re-focus on the relationships between economic fundamentals and the housing market of Hong Kong. While the aggregate GDP, population and longevity continue to grow, the real wage and household income fall behind. The trend component of the real GDP growth suffers a permanent downward shift after the first quarter of ...

How Persistent Are Unconventional Monetary Policy Effects?
The weight of the evidence indicates that unconventional monetary policy (UMP) shocks had persistent effects on yields. To make this point, this paper illustrates that the most influential SVAR model of UMP effects, which implies transient effects, exhibits structural instability, sensitivity to specification and single observations that render the conclusions unreliable. Restricted SVAR models that limit asset return predictability are more stable and imply that UMP shocks were persistent. This conclusion is consistent with evidence from micro studies, surveys of professional forecasters, ...

Financial Frictions, Financial Shocks, and Aggregate Volatility
I revisit the Great Inflation and the Great Moderation. I document an immoderation in corporate balance sheet variables so that the Great Moderation is best described as a period of divergent patterns in volatilities for real, nominal and financial variables. A model with time-varying financial frictions and financial shocks allowing for structural breaks in the size of shocks and the institutional framework is estimated. The paper shows that (i) while the Great Inflation was driven by bad luck, the Great Moderation is mostly due to better institutions; (ii) the slowdown in credit spreads is ...

Financial Frictions, Financial Shocks, and Aggregate Volatility
The Great Moderation in the U.S. economy was accompanied by a widespread increase in the volatility of financial variables. We explore the sources of the divergent patterns in volatilities by estimating a model with time-varying financial rigidities subject to structural breaks in the size of the exogenous processes and two institutional characteristics: the coefficients in the monetary policy rule and the severity of the financial rigidity at the steady state. To do so, we generalize the estimation methodology developed by Curdia and Finocchiaro (2013). Institutional changes are key in ...

Real-time inflation forecasting in a changing world
This paper revisits the accuracy of inflation forecasting using activity and expectations variables. We apply Bayesian-model averaging across different regression specifications selected from a set of potential predictors that includes lagged values of inflation, a host of real activity data, term structure data, nominal data, and surveys. In this model average, we can entertain different channels of structural instability by incorporating stochastic breaks in the regression parameters of each individual specification within this average, allowing for breaks in the error variance of the ...

Economic Forecasting in Theory and Practice : An Interview with David F. Hendry
David Hendry has made major contributions to many areas of economic forecasting. He has developed a taxonomy of forecast errors and a theory of unpredictability that have yielded valuable insights into the nature of forecasting. He has also provided new perspectives on many existing forecast techniques, including mean square forecast errors, add factors, leading indicators, pooling of forecasts, and multi-step estimation. In addition, David has developed new forecast tools, such as forecast encompassing; and he has improved existing ones, such as nowcasting and robustification to breaks. This ...
