The Optimal Inflation Rate and Firm-Level Productivity Growth
Weber, Henning - Institut für Weltwirtschaft (IfW) - 2012
Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A sticky-price model with firm-level productivity growth fits this data and predicts that the optimal long-run inflation rate is positive and between 1.5% and 2% per year. In contrast, the...

Distance to Frontier and the Big Swings of the Unemployment Rate: What Room is Left for Monetary Policy?
Huang, Kevin X.D.; Meng, Qinglai - Institut für Weltwirtschaft (IfW) - 2007

Applying the Samuelson … by itself has a quantitatively negligible effect and almost all strict inflation-targeting rules lead to indeterminacy … stickiness, indeterminacy is much less likely to occur as policy also responds to output. With estimated labor supply elasticity …

Growth and Unemployment in the Presence of Trend Inflation
Tesfaselassie, Mewael F. - Institut für Weltwirtschaft (IfW) - 2014
The standard search model of unemployment predicts, under plausible assumptions about household preferences, that disembodied technological progress leads to higher unemployment. This prediction is at odds with the experience of industrialized countries in the 1970s. This paper shows that...

Optimal inflation and firms' productivity dynamics
Weber, Henning - Institut für Weltwirtschaft (IfW) - 2011
Empirical data indicate that firms tend to have below-average productivity upon entry and that they tend to experience post-entry productivity growth. I present a New Keynesian model with growth in firm-specific productivity and firm turnover that captures these two phenomena. The model predicts...

Testing the New Keynesian Model on U.S. and Euro Area Data
Juselius, Mikael - Institut für Weltwirtschaft (IfW) - 2008
I apply the Johansen and Swensen (1999, 2004) method of testing exact rational expectations within the cointegrated VAR (Vector Auto-Regressive) model, to testing the New Keynesian (NK) model. This method permits the testing of rational expectation systems, while allowing for non-stationary...

Hidden Economies and the Socially Optimal Fiscal-Tax to Liquidity-Tax Ratio
Ercolani, Marco G. - Institut für Weltwirtschaft (IfW) - 2007
Differential tax analysis is used to show how the socially optimal fiscal-tax to liquidity-tax ratio changes with the relative size of the tax-evading hidden economy. The smaller the relative size of the hidden economy, the larger the optimal fiscal-tax to liquidity-tax ratio. The empirical...

Expectations, Monetary Policy, and Labor Markets: Lessons from the Great Depression
Reicher, Christopher P. - Institut für Weltwirtschaft (IfW) - 2009
This paper estimates a series of shocks to hit the US economy during the Great Depression, using a New Keynesian model with unemployment and bargaining frictions. Shocks to long-run inflation expectations appear to account for much of the cyclical behavior of employment, while an increase in...

The effect of inflation on real commodity prices
Reicher, Christopher; Utlaut, Johannes - Institut für Weltwirtschaft (IfW) - 2011
Recent research has shown that economic conditions have an important effect on real commodity prices. We quantify the contribution of fluctuations in inflation to this particular link. In the data, a temporary rise in inflation causes real commodity prices to rise, as does a rise in trend...

Strategic Complementarities and Optimal Monetary Policy
Levin, Andrew T.; Lopez-Salido, J. David; Yun, Tack - Institut für Weltwirtschaft (IfW) - 2007
In this paper, we show that strategic complementarities–such as firm-specific factors or quasikinked demand–have crucial implications for the design of monetary policy and for the welfare costs of output and inflation variability. Recent research has mainly used log-linear approximations to...

Regular Adjustment. Theory and Evidence
Konieczny, Jerzy; Rumler, Fabio - Institut für Weltwirtschaft (IfW) - 2007
We ask why, in many circumstances and many environments, decision-makers choose to act on a time-regular basis (e.g. adjust every six weeks) or on a stateregular basis (e.g. set prices ending in a 9), even though such an approach appears suboptimal. The paper attributes regular behaviour to...
