We characterize optimal state-dependent pricing rules under various forms of infrequent information. In all models, infrequent price changes arise from the existence of a lump-sum “menu cost.” We entertain various alternatives for the source and nature of infrequent information. In two...

This paper examines the theory of the Phillips curve, focusing on the distinction between "formation" of inflation expectations and "incorporation" of inflation expectations. Phillips curve theory has largely focused on the former. Explaining the Phillips curve by reference to expectation...

This paper examines in how far the DSGE model which is often dubbed the New Keynesian Consensus is compatibel with a Post-Keynesian or traditional Keynesian understanding of the economy. It is argued that while at first sight DSGE models seem to include a lot of traditional Keynesian or even...

Obtaining reliable data on capital is a recurring challenge when estimating economy-wide productivity growth, especially for developing countries. In this paper I construct energy-based productivity series which use energy consumption instead of capital when making such estimates. I first show...

Differently from Atkinson and Morelli (2011) who detect no clear link between increases in income inequality and systemic banking crises, we show that a large majority of crises occurred between 1982 and 2008 have been preceded by persistently high levels of income inequality. Such association...

This paper uses cross country regression analysis on a large set of countries to consider two hypotheses. The first is that increased public debt as a percentage of the economy reduces confidence in financial institutions. The second is that increased public debt relative to the economy lowers...

A rich literature from the 1970s shows that as inflation expectations become more and more ingrained, monetary policy loses its stimulative effect. In the extreme, with perfectly anticipated inflation, there is no trade-off between inflation and output. A recent literature on the interest-rate...

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...
