In this paper, we continue to explore the equilibrium theory under ambiguity. For a model of a pure exchange and asymmetric information economy with a measure space of agents whose exogenous uncertainty is described by a complete probability space, we establish a representation theorem for a...

The question: “How much of biological evolution based theories, as they are understood presently, apply to human behaviour?” is highly controversial and perhaps highly politicized as well. The inference that human beings are evolutionarily programmed to have urges toward aggression, rape,...

We study a Bertrand game where two sellers supplying products of different and unverifiable qualities can outwit potential clients through their (costly) deceptive advertising. We characterize a class of pooling equilibria where sellers post the same price regardless of their quality and low...

In a dynamic model of optimal security design, we show when firms should preserve "equity capacity" through choosing high target leverage or "debt capacity" through choosing low target leverage. Thereby, firms reduce a problem of underinvestment or overinvestment when they must raise future...

The role of small and medium enterprises (SMEs) in the fight against unemployment and economic activity stimulation is well established. Until today and due to lack of funding, Cameroon suffers of an unsustainable private sector constituted by SMEs at more than 90%; A situation which tends to...

Ken Arrow (1998) asks, “What has economics to say about racial discrimination?” He replies – entirely correctly – that racial “segregation within an industry – that is, firms with either all black or all white labor forces” – may be explained by economic theory, but “the...

Pay What You Want (PWYW) pricing has received considerable attention recently. Empirical studies show that a PWYW pricing mechanism is able to increase a seller’s turnover and profit. This paper addresses PWYW pricing for bundles of experience goods. The paper shows that a PWYW pricing...

The standard explanation of wage rigidity in principal agent and in efficiency wage models is related to worker risk-aversion. However, these explanations do not consider at least two important classes of empirical evidence: (1) In worker cooperatives workers appear to behave in a less risk...

This paper offers a dynamic model of the foreign exchange market where some investors in the market are more informed than others. By adjusting the proportion of informed investors in the market, it is shown that the disconnect between macroeconomic variables and the exchange rate is sensitive...

The decision to cooperate within R&D joint ventures is often based on `expert advice.' Such advice typically originates in a due diligence process, which assesses the R&D joint venture's profitability, for example, by appraising the achievability of synergies. We show that if the experts who...
