The Phillips curve has been in the focus of many key debates in macroeconomics ever since Samuelson and Solow (1960) modified the original curve in linking the unemployment rate to the inflation rate. This essay analyzes the links of the modern discussion to the debates over time highlighting...

A Nash equilibrium can also be seen as a Cournot-Nash equilibrium, though this is debated because Cournot provided a specific application, not a general formulation. In my view, another of Nash's fundamental contributions stands out when contrasting him to Cournot. Cournot treated economic...

Limited memory capacity, retrieval constraints and anchoring are central to expectation formation processes. We develop a model of adaptive expectations where individuals are able to store only a finite number of past experiences of a stochastic state variable. Retrieval of these experiences is...

This paper extends the efficiency wages/partially adaptive expectations Phillips curve, otherwise known as the price-price Phillips curve, from a closed economy context to an open economy one with both commodity trade and capital mobility. We also consider the case of a monetary union (a...

I examine fiscal policy uncertainty in a context where market participants learn about the conduct of fiscal policy with regression rules for dependent variables including tax revenue, net transfers, government spending, and government debt. The explanatory variables include lagged fiscal...

Why is there no Milton Friedman today? For two reasons. The young Milton Friedman emerged from a cloistered hold-out against the Age of Keynes; as such he was a battle-tested master of ingenuity and subterfuge. The accomplishments of those years cannot be replicated by the dominant and dogmatic...

The BoltzmannGibbs distribution is currently widely used in economic modeling. One of the applications is integrated with the DSGE (Dynamic Stochastic General Equilibrium) model. However, a question that arises concerns whether the BoltzmannGibbs distribution can be directly applied, without...

This paper describes the out-of-equilibrium approach to the analysis of economic processes. We argue that such an approach is adapted to study qualitative (or structural) changes, like technical progress or changes in preferences. Truly sequential analyses manage to capture the essential...

The pervasiveness of expectations in economic analysis has created significant discussion on the merits and demerits of the two main expectations formation hypotheses, adaptive and rational expectations. This paper gives concise outlines of the two hypotheses and reviews their respective...

We study a simple monetary model in which a central bank faces a boundedly rational private sector and has the goal of stabilizing inflation. The system’s dynamics is generated by the interaction of the expectations about inflation of the various agents involved. A modest degree of...

We propose a new approach to test the full-information rational expectations hypothesis which can identify whether rejections of the arise from information rigidities. This approach quantifies the economic significance of departures from the and the underlying degree of information rigidity....
