Prior studies have shown that traders quickly converge to the price-quantity equilibrium in markets for goods that are immediately consumed, but they produce speculative price bubbles in resalable asset markets. We present a stock-flow model of durable assets in which the existing stock of assets is subject to depreciation and producers may produce additional units of the asset. In our laborato...

Stock markets play a fundamental role in the countries’ economies, since they allow companies to raise funds for their investments in technology, expansion or infra-structure by selling stocks to the public. At the same time, stocks are, for the stockholders, important assets that can help to maintain or increase the investor’s wealth for future use, like retirement, education, etc. On the othe...

modern portfolio theory is based on harry markowitz's 1952 work on mean-variance portfolios. he stated that a rational investor should either maximize his expected return for a given level of risk, or minimize his risk for a given expected return. in this study the markowitz model with cardinality constraints was studied. we extend the standard model to include cardinality constraints that...

This paper studies the exposure of the stock prices of Australian gold-mining firms to changes in gold prices and the valuation effects of gold price exposure. Goldmining firms have significant gold price exposure; the price of the average goldmining stock moves 0.76% for each 1.00% change in Australian-dollar-denominated gold prices. Evidence from the behaviour of stock price sensitivities sug...

“Normality” of Stock Prices Bo Shi Abstract. The Black-Scholes Model, often simply called Black-Scholes, models the varying price of financial instruments over time: stocks in particular. This model assumes that returns on the underlying stock are lognormally distributed, which can be reasonable for many assets that offer options. However, from a selection of 100 stock histories, I found that a...

Ads of stocks and mutual funds typically tout their past performance, despite a disclosure that past performance does not guarantee future returns. Are consumers motivated to buy or sell based on past performance of assets? More generally, do consumers (wrongly) use sequential information about past performance of assets to make suboptimal decisions? Use of this heuristic leads to two well-know...

In this paper it is demonstrates that if assets are priced according to Black’s (1972) CAPM, then tests on the cointegrated VAR can reveal evidence for or against integration of financial markets. If the market portfolios cointegrate one-to-one and share the same deterministic long-run trend, the markets obey the law of one price. Furthermore, it is shown how the driving force of the prices can...
