Article
We examine the case of a firm holding the option to make an uncertain and irreversible investment. The firm is decentralized and there is information asymmetry between the owner and the investment manager regarding the price of an input (e.g. a key equipment) that needs to be purchased by an outside supplier with market power. We show that the tota...

We find the optimal time for exercising a jointly held investment option. When the input market is competitive, the investment can take place earlier, later, or exactly when the optimal investment threshold is reached depending on how the option holders interact and on the bargaining power distribution. When instead the input supplier has market po...

Reliability Options (ROs) are used to enhance the security of supply in electricity systems. When a power producer writes a RO, s/he agrees to set a cap on the price of electricity that s/he cashes. In return, the system operator, i.e. the party that is buying the option, pays to the option issuer a fixed premium. In this paper we analyze how ROs a...
Article
We study how overlapping ownership affects investments in a preemption race with market uncertainty. Internalization of rival payoffs delays follower entry if product market effects are moderate, implying longer incumbency which intensifies the race to lead. Preemptive and follower investment thresholds increase with volatility as in standard real...
Article
We study the optimal design of Public-Private Partnerships (PPPs) when there is unobservable action on the private party’s side. We show that if the private party does not have negotiating power over the project’s surplus, then no inefficient delays are attributable to the moral hazard issue. However, if the private party has negotiating power, the...

This paper considers the case of a multinational corporation who holds the option to invest in a foreign country. The company incurs the investment cost and gains access to a volatile profit flow once the project becomes operational. The cost is entirely sunk so the investor must account, not only for uncertain market conditions, but also for the t...

We study how common ownership affects the magnitude and dynamics of investments in a duopoly. Followers exhibit less aggressive timing and quantity reactions because they internalize their effects on leaders. Leaders are therefore more likely to opt for a deterrence strategy, but their own internalization of followers softens their decisions. If fi...
Article

Substantial R &D efforts are currently directed towards the development of combined heat and power (CHP) systems that automatically and seamlessly connect to the power grid. In this paper we develop a real options model to assess the impact that the operational flexibility characterizing such systems will have on the optimal timing and capacity ass...
Article
We develop a real options model to assess the impact of decoupled payments on agricultural investments. The context that we are addressing is the one set by the Common Agricultural Policy where farmers are eligible for decoupled payments as long as their land is properly maintained. We show that decoupled payments are non-neutral with respect to ch...

Billette de Villemeur et al. [Billette de Villemeur, E., Ruble, R. and Versaevel, B. [2014] Investment timing and vertical relationships, Int. J. Industrial Organization 33, 110–123] discuss the case of a firm undertaking a project in order to serve an uncertain demand. They show that when the investor requires an outside supplier with market power...

Billette de Villemeur et al. (2014. International Journal of Industrial Organization, 33, pp. 110-123) discuss the case of a firm undertaking a project in order to serve an uncertain demand. They show that when the investor requires an outside supplier with market power to provide it with a needed input, the investment occurs too late from an indus...

Under the current version of the Common Agricultural Policy (CAP), payments to EU farmers are decoupled from the production of agricultural commodities. In fact, farmers qualify for CAP support as soon as their land is maintained in good agricultural and environmental condition. In this paper, we study how decoupled payments influence the decision...
