four models of aggregate supply • In the four models that follow, the short-run aggregate supply curve is not vertical because of some market imperfection. As a result, output can deviate away from its natural rate. • Consider the following 'surprise-supply' function: • where Y is output, Y* is the natural rate of output, P is the

To fully appreciate the impact of imperfect information, we will rst examine a perfect information case, thereby understand the necessity of the model in generating incomplete adjustments. To that end, we will rst adopt the following assumptions. 1. There are many di ering goods produced in the economy. 2.

The second model is the imperfect-information model. As in the worker-mispercep-tion model, this model assumes that there is imperfect information about prices. Here, though, it is not workers in the labor market who are fooled: it is suppliers of goods who confuse changes in the price level with changes in relative prices. If a producer

In other words, when a rm observes a price change, it is possible that the price is a change in relative prices, so that it will have implications on its production decision.

PDF The Lucas Imperfect Information Model

Based on the work of Lucas (1972) and Phelps (1970), the imperfect information model represents an important milestone in modern economics. The essential idea of the model is that producers' inability to distinguish between price movements due to relative price changes (to which they should respond) and

Introduction to the Aggregate Supply–Aggregate Demand Model

The next three chapters take up this task. This chapter introduces the macroeconomic model of aggregate supply and aggregate demand, how the two interact to reach a macroeconomic equilibrium, and how shifts in aggregate demand or aggregate supply will affect that equilibrium. This chapter also relates the model of aggregate supply and aggregate

Problem : What are the four major models of aggregate supply? There are four major models that explain why the short-run aggregate supply curve slopes upward. The first is the sticky-wage model. The second is the worker-misperception model. The third is the imperfect-information model. The fourth is the sticky-price model.

imperfect information model of aggregate supply A more sophisticated analysis of the aggregate supply equation concludes that the SRAS curve is upward sloping. The four different models used to explain an upward sloping SRAS curve are: (1) the sticky-wage model, (2) the worker-misperception model, (3) the imperfect-information model, and (4) the sticky-price model.

Aggregate Supply - an overview | ScienceDirect Topics

The main alternative to models of imperfect information and aggregate supply are models based on sticky prices. Indeed, in much of the recent business-cycle literature, the norm for explaining price adjustment is some version of the Calvo (1983) model. A full comparison of these approaches is beyond the scope of this chapter.
