China’s external capital market has been developing rapidly since the establishment of its stock markets. However, financing from the internal capital market, especially through the guarantee system provided by other associated firms (the guarantee circle), remains significant for some Chinese firms. We analyze the importance associated with the guarantee system in China with a focus on the mac...

This study examines the financing choices of firms operating in a weak institutional environment. We argue that in relationship-based systems, global financing and strong political connections are alternative means to create firm value. Well-connected firms might be less inclined to access global capital markets because (state-owned) domestic banks provide capital at low cost. Moreover, the exp...

This paper estimates the implied cost of equity for Canadian and U.S. firms using a methodology based on the dividend discount model and utilizing firms’ current stock price and analysts’ forecasted earnings. We find that firm size and firm stock liquidity are negatively related to cost of equity, while greater firm financial leverage and greater dispersion in analysts’ earnings forecasts are a...

We propose and investigate a new channel through which the resource curse a stylized fact that countries rich in natural resources grow slower operates. Predatory governments are more likely to expropriate corporate profits in natural resource industries when the price of resources is higher. Corporations whose profits are more dependent on the price of resources can mitigate the risk of exprop...

Aβ folding and assembly are believed to be seminal pathogenic events in Alzheimer’s disease. We study Aβ(1-42) folding by discrete molecular dynamics using a four-bead protein model with hydrogen bonds and amino acid-specific interactions. Interactions account for hydrophobic/hydrophilic effect that mimic the solvent as well as electrostatic effects. We study monomer conformations on a wide tem...
