In this research, overreaction and underreaction have been studied by assessing profitability and excess returns of investment strategies and evaluating price adjustment speed in short and long terms. The results showed that the momentum investment strategies had higher annual returns in comparison to contrarian strategies in all short and long periods which led to confirmation of underreaction...

Gradual information diffusion model predicts that as private information travels across the population, pricing accuracy would improve and asset prices would exhibit momentum as a result. In laboratory markets I investigate the market’s aggregation capacity in response to varying proportions of informed traders as a consequence of information diffusion. The results demonstrate that pricing erro...

There is a large and growing literature documenting the relation between ex ante observable variables and stock returns. Importantly, much of the evidence on the relation between returns and observable variables like market capitalization, the ratio of price/book, and prior price change has been portrayed in the context of returns to simulated portfolio strategies. Often missing in these analys...

Asset market experiments are analyzed by distinguishing, ex post facto, participants who trade on fundamentals versus those who trade on momentum (i.e., buying when price is rising). The distinction is made when prices are above fundamental value, so that (in each period) those who have more offers than bids (net offerers) are classified as fundamentalists while those who have more bids than of...

the main objective of this study was to evaluate the response of consumers to changes in income and prices of chicken meat in the short run and long run. in order to achieve this goal, vector auto regression (var) and vector error correction model (vecm) have been applied to data since 1974 to 2007. impulse response function (irf) calculation indicated that past and present consumption of chick...
