Book Description
A crucial challenge for economists is figuring out how people interpret the world and form expectations that will likely influence their economic activity. Inflation, asset prices, exchange rates, investment, and consumption are just some of the economic variables that are largely explained by expectations. Here George Evans and Seppo Honkapohja bring new explanatory power to a variety of expectation formation models by focusing on the learning factor. Whereas the rational expectations paradigm offers the prevailing method to determining expectations, it assumes very theoretical knowledge on the part of economic actors. Evans and Honkapohja contribute to a growing body of research positing that households and firms learn by making forecasts using observed data, updating their forecast rules over time in response to errors. This book is the first systematic development of the new statistical learning approach. Depending on the particular economic structure, the economy may converge to a standard rational-expectations or a "rational bubble" solution, or exhibit persistent learning dynamics. The learning approach also provides tools to assess the importance of new models with expectational indeterminacy, in which expectations are an independent cause of macroeconomic fluctuations. Moreover, learning dynamics provide a theory for the evolution of expectations and selection between alternative equilibria, with implications for business cycles, asset price volatility, and policy. This book provides an authoritative treatment of this emerging field, developing the analytical techniques in detail and using them to synthesize and extend existing research.

Book Description
Introducing bounded rationality into a standard consumption based asset pricing model with a representative agent and time separable preferences strongly improves empirical performance. Learning causes momentum and mean reversion of returns and thereby excess volatility, persistence of price-dividend ratios, long-horizon return predictability and a risk premium, as in the habit model of Campbell and Cochrane (1999), but for lower risk aversion. This is obtained, even though we restrict consideration to learning schemes that imply only small deviations from full rationality. The findings are robust to the particular learning rule used and the value chosen for the single free parameter introduced by learning, provided agents forecast future stock prices using past information on prices.

Book Description
Since a vast number of investment funds are available at the market, it may be difficult for investors to figure out which fund might serve their needs the best. Especially in times where the uncertainty in the market increases, it might be even more important to figure out how investment funds response to such volatility shocks. Volatility as a risk measure may not be constant over time, but tight connected to the market risk in contrast. Hence, the exploration of the investment fund's volatility response to shocks in the stock market may give a deeper understanding of what the actual risk of an investor might be.

Book Description
Herbert A. Simon has been a leading contributor to cognitive psychology, computer science, public administration, philosophy and statistics, and is the winner of the 1978 Nobel Memorial Prize in economics. As this collection demonstrates, his impact on economics has been felt in areas as diverse as the theory of the firm and economic organization, consumer behaviour, law and economics, and environmental economics. Central to his work is the notion of bounded rationality - the mismatch between human decision-making capacities and the scale of the decision problems that people face, which results in satisficing rather than optimizing behaviour - and his belief that economic research should start from the study of actual behaviour rather than being based on convenient but unrealistic assumptions. Peter Earl's choice of articles shows both the kind of economics that emerges when Simon's philosophy is followed comprehensively, and what happens when neo-classical economists partially adopt his ideas.

Book Description
This study is an attempt to model the volatility of stock returns in Indian market for the period 1997-2006 using GARCH, TARCH and E-GARCH. Results point out that returns exhibit persistence and volatility clustering in both NSE Nifty and BSE Sensex. Asymmetric volatility effect has been observed in both the series using TARCH and E-GARCH model. While forecasting returns it is found that GARCH-M performs better compared to alternative econometric models, namely, RW, OLS, GARCH, GARCH-M, TARCH and E-GARCH models. It is revealed that one-step ahead forecast improves by using GARCH and its variant models, which goes against the concept of random walk hypothesis. Results of this study also indicate that certain anomalies still exist which makes the stock market inefficient. In this context, SEBI is expected to play proactive role in a manner, which makes market capable to value the intrinsic price of assets.

Book Description
This book is about the joint dynamics of stock returns and trading volume. We propose a dynamic equilibrium model in which agents have rational expectations and are heterogeneous in their investment opportunity. The dynamics of stock returns and trading volume implied by the model can explain the main empirical regularities found in high frequency stock data: (i) Time varying volatility. (ii) Positive volume-volatility relation. (iii) Ambiguous volume-persistance relation. Finally, the model is tested using efficient method of moments.
