Final answer:
Forecasting in business, particularly in the stock market, relies on forming realistic expectations for future performance based on all available information.(option a) The contrast is between rational expectations, which use comprehensive data, and adaptive expectations, which rely on historical trends. Stock market forecasting emphasizes potential future outperformance that defies current expectations.
Step-by-step explanation:
The objective of forecasting is to develop a set of realistic expectations for future value-relevant payoffs. Forecasting involves using rational expectations to form the most accurate expectations about the future, with individuals utilizing all information available. This approach contrasts with adaptive expectations, where predictions are made based on past experiences without a strong emphasis on forward-looking insights. In the context of the stock market, the essence of forecasting is not just to predict future earnings, but to identify companies for which the current expectations are poor yet which may outperform in the future.
Furthermore, an economist constructing a model to predict stock market outcomes is likely relying on neoclassical analysis which suggests that, in the long run, the economy adjusts back to its potential GDP level output through flexible price levels. However, in the short-term, the economist’s model acknowledges that expectations, accurate or otherwise, play a critical role in determining stock prices as market participants react to new information.
