We show that the problem of whether two Turing Machines are functionally equivalent is undecidable and explain why this is significant for the theory of repeated play and evolution.

We develop a model of consulting (advising) where the role of the consultant is that she can reveal signals to her client which refine the client’s original private estimate of the profitability of a project. Importantly, only the client can observe or evaluate these signals, the consultant...

An important line of recent literature has found gender differences in attitudes toward competition, with men being more likely to choose competitive incentive schemes, even when factors such as ability and risk aversion are controlled for. This paper examines the effect of information on the...

We characterize equilibria of oligopolistic markets where identical firms with constant marginal cost compete a' la Cournot. For given maximal willingness to pay and maximal total demand, we first identify all combinations of equilibrium consumer surplus and industry profit that can arise from...

We analyze a model in which individuals have hereditary reproductive types. The reproductive value of an individual is determined by her reproductive type and the amount of resources she can access. We introduce the possibility of suicide and assume it is also a genetic trait that interacts with...

This paper considers a dynamic economy in which agents are repeatedly matched with one another and decide whether to enter into profitable partnerships. Each agent has a physical colour and a social colour. The social colour of an agent acts as a signal about the physical colour of agents in his...

We provide a model that links the high return to venture equity to the impatience of the VCs. VCs are scarce, and hence, they have market power and a high return on their investments. As a result, VCs are eager to terminate non-performing ventures so they can move on to new ones. The scarcity of...

The PRISM method is a risk assessment approach that focuses on hidden-risk identification and ranking. The combined AHP-PRISM method was created for strategic assessments based on pairwise comparisons. The PRISM and AHP-PRISM methods have remarkable visual decision support and control functions...

We study an economy in which there is always double coincidence of wants, agents have perfect information about qualities of goods, and there are no transaction costs. The hold-up problem arises because efforts invested in improving quality prior to search may not be compensated in the market....
