We build quadratic labor adjustment costs into an otherwise standard New-Keynesian model of the business cycle and show that this is sufficient to increase both, output and inflation persistence. -- Monetary persistence ; labor adjustment costs

A growing body of empirical evidence shows that there exists a long-run positive tradeoff between inflation and real macroeconomic activity. Within a New Keynesian framewok, we examine how increasing returns generate a positive long-run relation between inflation and output.

We explore the far-reaching implications of replacing current unemployment benefit (UB) systems by an unemployment accounts (UA) system. Under the UA system, employed people are required to make ongoing contributions to their UAs and the balances in these accounts are available to them during...

This paper analyses how and to which degree the Danish flexicurity concept and its various elements achieve the renowned Danish miracle by evaluating their unemployment and inequality effects and their complementarities. We develop a microfounded model of searching workers and firms, calibrate...

We present a proposal for reforming unemployment assistance in Germany through the introduction of unemployment accounts (UAs). Instead of paying taxes that finance the unemployment assistance, employed people make ongoing contributions to their UAs and can make withdrawals from these accounts...

This paper describes the practical implementation of hiring vouchers in Germany (Kiel Working Paper 1302 "Comparing the Effectiveness of Employment Subsidies" by Alessio Brown, Christian Merkl and Dennis Snower). According to our proposal employers receive vouchers for hiring longterm...

Using a standard dynamic general equilibrium model, we show that the interaction of staggered nominal contracts with hyperbolic discounting leads to inflation having significant long-run effects on real variables.

A major criticism against staggered nominal contracts is that they give rise to the so called "persistency puzzle" - although they generate price inertia, they cannot account for the stylised fact of inflation persistence. It is thus commonly asserted that, in the context of the new Phillips...

This paper argues that there is a nonzero inflation-unemployment tradeoff in the long-run due to frictional growth, a phenomenon that encapsulates the interplay of nominal staggering and money growth. The existence of a downward-sloping long-run Phillips curve suggests the development of a...

This paper takes a new look at the long-run dynamics of inflation and unemployment in response to permanent changes in the growth rate of the money supply. We examine the Phillips curve from the perspective of what we call "frictional growth," i.e. the interaction between money growth and...
