This paper examines a decision-making problem of rational agents with risk averse utilities in the financial market both in statics and in dynamics. In the financial market there are two securities, one risky security and one riskless bond, and a continuum of investors with heterogeneous...

It is a well known fact that local scale invariance plays a fundamental role in the theory of derivative pricing. Specific applications of this principle have been used quite often under the name of `change of numeraire', but in recent work it was shown that when invoked as a fundamental first...

Static time series models usually assume stationarity, normality, and independence for the increments of financial rates of return. This paper investigates the empirical characteristics of financial rates of return from Latin American stock and currency markets and documents that their empirical...

We show how payoff spaces can be used to study minimum-variance unbiased estimators and give a proof of Barankin's theorem for finite sample spaces and for samples of size one.

This paper analyses a temporary financial market equilibrium by considering a two-period model of asset pricing with s securities, one riskless bond, and a continuum of heterogeneous agents with different preferences, endowments, and beliefs. Investors' objectives are to maximize the expected...

Riding the yield curve, the fixed-income strategy of purchasing a longer-dated security and selling before maturity, has long been a popular means to achieve excess returns compared to buying-and-holding, despite its implicit violations of market efficiency and the pure expectations hypothesis...

We develop a valuation formula for analyzing high growth firms using the stages of an industry lifecycle. Our model is best suited for start-up firms with low (or negative) earnings and low sales. Our formula uses start-up firm data and captures the firm’s growth potential by incorporating...

From the CAC40 French stock index, we induce the implied market factor’s level through the inversion of a closed form pricing formula for European calls on the CAC40. For this purpose, we assume that the CAC40 index is a disturbed observation of the actual market factor, the market factor’s...

We analyse the equilibrium consequences of performance-based contracts for fund managers. Managerial remuneration is tied to a fund's absolute performance and its performance relative to rival funds. Investors choose whether or not to delegate their investment to better-informed fund managers;...

Recently there has been some interest in the credit risk literature in models which involve stopping times related to excursions. The classical Black-Scholes-Merton-Cox approach postulates that default may occur, either at or before maturity, when the firm's value process falls below a critical...
