This Paper presents a new approach to the theory of the firm by identifying factor complementarities as central to the determination of the firm’s boundaries. The factor complementarities may take a variety of forms: technological and informational complementarities, as well as economies of...

This Paper integrates microfoundations of wage staggering into a simple dynamic general equilibrium model with rational expectations. In this context we show that a permanent increase in money growth leads to a permanent increase in the rate of inflation and a permanent reduction in the level of...

Do firms reduce employment when their insiders (established, incumbent employees) claim higher wages? The conventional answer in the theoretical literature is that insider power has no influence on employment, provided that the newly hired employees (entrants) receive their reservation wages....

The Paper examines the possible effects of introducing a large-scale welfare reform in Sweden, namely, the introduction of comprehensive welfare accounts. Under this policy, individuals make mandatory contributions to accounts, which they can top up with voluntary contributions. In return,...

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...

Macroeconomic shocks and labour-market institutions jointly determine employment growth and economic performance. The effect of shocks depends on the nature of these institutions, and the effect of institutional change depends on the macroeconomic environment. It follows that a given set of...

This Paper surveys major empirical regularities concerning changes in earnings inequality in Europe and the US over the past 25 years. Next, it indicates which of these regularities can be explained within the competitive demand–supply framework of analysis and what is left unexplained....

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...

The East German labour market has hardly made any progress since German reunification, despite massive migration flows and support from the West. We argue that East Germany is in trouble precisely because of the support it has received. This paper explores the phenomenon of 'the caring hand that...
