Establishing Initial Conditions in Support of Inflation Targeting

This paper provides some practical advice on establishing initial conditions in support of an inflation-targeting monetary framework. These conditions are divided into four areas: a mandate in support of an inflation objective and accountability for achieving this objective; macroeconomic stability; a sufficiently well-developed and stable financial system; and effective policy implementation tools. The measures taken by countries to meet these conditions are also reviewed.

The Use and Abuse of Taylor Rules: How Precisely Can We Estimate Them?

This paper draws attention to inconsistencies in estimating simple monetary policy rules and their implications for policy advice. We simulate a macroeconomic model with a backward reaction function similar to Taylor (1993). We estimate different versions of a policy rule, using these simulated data. Under certain circumstances, estimations document an illusionary presence of a lagged interest rate, or of forward-looking behavior. Our results are consistent with the fact that several authors found very different versions of monetary policy rules, all fitting the U.S. data well. We also survey the literature, providing a list of issues complicating practical use of Taylor rules.

Inflation Smoothing and the Modest Effect of VAT in Germany

Increases in German core inflation following the 2007 VAT hike were smaller than expected, leading to speculation about delayed inflationary effects. This paper argues to the contrary that price increases in advance of the VAT hike explain the small increase upon implementation. We find that core inflation rose by 0.36 percentage point in the run up and by a further 0.40 percentage point at the time of the VAT hike. Cumulatively, the tax hike contributed to two thirds of the increase in core inflation in 2006-07 at an estimated pass-through of 73 percent. Most of the increase in 2006 was of general nature, while about one sixth can be attributed to durable goods and items with low degree of competition.

Globalization and the New Normal

This study expands the empirical specification of Cerra and Saxena (2008), and allows short-term output growth regimes to be determined by globalization. Relying on a non-linear dynamic panel representation, it reconciles the earlier results in the literature regarding the two opposite narratives of the effects of globalization on output growth. Countries experience higher growth, on average, the more open and integrated they are into the world. However, once they reach a certain globalization threshold (endogenously estimated), countries may also experience a new normal, persistently lower short-term output growth following a financial crisis. The benefits, as well as vulnerabilities, accrue earlier in the globalization process for low- and middle-income countries. To solely reap the globalization benefits on growth, sound policies should be in place to mitigate the negative effects stemming from increased vulnerabilities brought by globalization.
