In this paper a two-sector growth model allowing indeterminacy to occur at relatively mild degrees of increasing returns is developed. It is shown that these economies of scale need only be present in one sector of the economy (investment). This feature of the model, therefore, builds on...

In this paper a dynamic model of monopolistic competition with entry and exit has been presented and examined. It is shown that the model displays indeterminacy at modest degrees of increasing returns in cases where the market power in the consumption goods market and in the investment goods...

Payroll taxes represent a major distortionary influence of governments on labor markets. This paper examines the role of payroll taxation and the social safety net for cyclical fluctuations in an nonmonetary economy with labor market frictions and unemployment insurance, when the latter is only...

This paper evaluates complementarities of labor market institutions and the business cycle in the context of a stochastic dynamic general equilibrium model economy. Matching between workers and vacancies with endogenous time spent in search, Nash-bargained wages, payroll taxation, and...

This paper derives new results on the effects of employing Taylor rules in economies that are subject to real market imperfections such as production externalities. Taylor rules that aggressively respond to output can eliminate sunspot equilibria that arise from the increasing returns. The paper...

The paper finds empirical evidence on the ripple effect of sunspots on the interwar German economy. It identifies a sequence of negative shocks to expectations for the 1927 to 1932 period. The artificial economy predicts the 1928-1932 depression and a long boom from 1933 onwards. Overall, a...

We show that an otherwise standard one-sector real business cycle model with variable capital utilization and mild increasing returns-to-scale is able to generate qualitatively as well as quantitatively realistic aggregate fluctuations driven by news shocks to two formulations of future...

Recent empirical evidence suggests that product creation is procyclical and it occurs largely within existing fi rms. Motivated by these findings, the current paper investigates the role of intrafi rm product scope choice in a general equilibrium economy with oligopolistic producers. We show...

This paper reviews the performance of the East German economy in the turbulent quarter-century following reunification and draws some conclusions for the reunification of North and South Korea. In this period, the gap in output per capita between East and West Germany declined at a speed not far...

The paper re-examines whether the Federal Reserve's monetary policy was a source of instability during the Great Inflation by estimating a sticky-price model with positive trend inflation, commodity price shocks and sluggish real wages. Our estimation provides empirical evidence for substantial...
