The rate of information diffusion and, consequently, price discovery are conditional not only upon the design of the market microstructure but also the informational structure. This paper presents a market microstructure model showing that an increasing number of information hierarchies among...

The study investigates the price behavior after initial public offerings (IPOs) listed on the Warsaw Stock Exchange from 2004 to 2009. It focuses on possible explanations for the IPO phenomenon within the context of Poland and provides evidence on the relation between both the company size and...

Determining the cost of equity is one of the most difficult problems in corporate finance. In this paper, we present a simple estimation example using an internet start-up company. We use public firm comparables for beta, making adjustments for leverage using Harris and Pringle’s (1985)...

Michael Powers licensed a series of domain names that he thought would allow him to create a profitable set of online tourism marketing sites. The case asks students to evaluate the feasibility of the business, given Michael’s projections. Given what they find, students are then asked to...

There is no consensus in the literature as to which model should be used to estimate stock returns and the cost of capital in the emerging markets. The Capital Asset Pricing Model (CAPM), which is most often used for this purpose in the developed markets, has a poor empirical record and is...

In the present study we assess the dependency structure between stock indexes by econometrically estimating the empirical copula function and the parameters of various parametric copula functions. The main finding is that the t-copula and the Gumbel-Clayton mixture copula are the most...
