Recent research shows that several DSGE models provide a closer fit to the data under adaptive learning. This paper extends this research by introducing adaptive learning in the model of Krusell and Smith (1998) with uninsurable idiosyncratic risks and aggregate uncertainty. A first contribution...

It is generally agreed that within long-term relationships agents learn the characteristics of their market partners better than through spot transactions. In contrast, little is known on how relationship-based and transaction-based markets compare when agents learn about the aggregate economy...

A prominent feature of the Kiyotaki–Wright model of commodity money is multiplicity of dynamic equilibria. We show that the extent of multiplicity hinges on the frequency of search. Holding fixed the average number of meetings over time, we vary search frequency by altering the interval...

This paper provides a mathematical foundation for independent random matching of a large population, as widely used in the economics literature. We consider both static and dynamic systems with random mutation, partial matching arising from search, and type changes induced by matching. Under...

Monetary shocks largely affect economic activity in Western Australia. In smaller proportion, those shocks generate contractions in New South Wales, Victoria and South Australia, while economic activity in Queensland is significantly less affected. Finally, we develop a new approach to uncover...

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...

The Phillips Curve (hereafter PC) is widely viewed as dead, destined to the mortuary scrapyard of discarded economic ideas. The coroner's evidence consists of the small standard deviation of the core inflation rate in the past two decades despite substantial volatility of the unemployment rate,...

This paper is a non-technical and somewhat philosophical essay, that seeks to investigate the relationship between economics and reality. More precisely, it asks how reality in the form empirical evidence does or does not influence economic thinking and theory. In particular, which role do...

We show that policy uncertainty about how the rising public debt will be stabilized empirically accounts for the lack of deflation in the US economy during the zero-lower-bound period. Announcing fiscal austerity is detrimental in the short run, but it preserves macroeconomic stability. On the...

We develop a theoretical framework to quantitatively assess the general equilibrium effects and welfare implications of central bank reputation and transparency. Monetary policy alternates between periods of active inflation stabilization and periods during which the emphasis on inflation...
