In this paper, the standard two-period general equilibrium model with incomplete financial markets is considered. First, existence of equilibrium is proved using a stationary point argument on the set of no-arbitrage prices. Prices are normalized with respect to the market portfolio. The proof...

As becomes apparent from the standard text books in industrial organization (cf. Tirole, 1988, The Theory of Industrial Organization), the analysis of the effects of uncertainty within this field is yet underdeveloped. This paper shows that the new theory of strategic real options can be used to...

This paper re-examines gold's role as a tool for investors to manage their portfolio risk. We begin by assessing gold's average relationship to an investor's diversified equity portfolio by applying the basic Capital Asset Pricing Model (CAPM) to UK and US equity indices. Next, we apply a...

We analyze the interaction between firms' payout policies and their decisions in product markets in a continuous-time stochastic game between two firms. One of these is financially constrained, whereas the other is not. Contrary to the standard literature we allow firms to choose production and...

We analyse the short term work (STW) regulations that several OECD countries introduced after the 2007 financial crisis. We view these measures as a collection of real options and study the dynamic effect of STW on the endogenous liquidation decision of the firm. While STW delays a firm's...

This paper considers investment problems in real options with non-homogeneous two-factor uncertainty. It shows that, despite claims made in the literature, the method used to derive an analytical solution in one dimensional problems cannot be straightforwardly extended to problems with two...

This paper analyses the exercise decision of non-exclusive real options in a two-player setting. A general model of non-exclusive real options, allowing the underlying asset to follow any strong Markov process is developed, thus extending the existing literature, which is mainly based on...

We present a stochastic dynamic model of the adjustment of betting odds by bookmakers in a horse-racing betting market. We use optimal stopping theory in a two-horse benchmark model with both informed and noise punters. A costly learning process discloses what information the informed traders...
