We consider which readily observable characteristics of individual stocks (e.g., option implied volatility, accounting data, analyst data) may be used to forecast subsequent extreme price movements. We are the first to explicitly consider the predictive influence of option implied volatility in...

A model is presented to characterise the (optimal) demand for cash balances in deregulated markets. After the model of James Tobin, 1958, net balances are determined in order to maximise the expected return of a certain portfolio combining risk and capital. Unlike the model of Tobin, the prices...

An alternative theoretical setting is presented to characterise the money demand and the monetary equilibrium. Two main hypotheses are stated that contradict the assumptions normally sustained by scholars and policy-makers: National output is assumed to be a random variable, and people are...

This paper develops a model of valuation of investment projects which includes nano-medical scientific and industrial dynamics, and its regulation. First critically analyzes the literature on valuation of investments, arguing that the methodology of real options is the most appropriate. It is a...

Consider an agent who holds a stock, but is allowed to buy and hold some quantity of at-the-money put options on the stock. Such an agent must decide the optimal use of financial derivatives under trade restrictions. This paper uses simulation to compare the optimal quantity when the agent...
