This monograph sets the stage for experiments by first examining a sample data set that looks very much like the typical historical data one gathers from the field, only it was actually generated in the laboratory so that we know what really went on. The example demonstrates how misleading the...

Arbitrage pricing theory states that the expected return of an asset portfolio is related to factors characterizing the economy and could be associated to macroeconomic variables. In this paper, we consider equity traded in the Chilean stock market to empirically contrast the APT in its...

Practical portfolio investment problems under uncertainty can be modeled well as multiperiod stochastic programs. However, the numerical optimization methods that need to be used to solve such models seriously limit the level of detail in the uncertainty about future asset prices and returns...

Faced with the problem of pricing complex contingent claims, an investor seeks to make his valuations robust to model uncertainty. We construct a notion of a model- uncertainty-induced utility function and show that model uncertainty increases the investor's eff ective risk aversion. Using the...

This paper reviews different schools of thought on the question of if and how personal taxes should be incorporated into the valuation of companies or projects. The paper shows under which conditions the risk-neutral valuation approach yields the same result as the Tax-CAPM. Special cases are...

This paper provides conditions on the primitives of a continuous-time economy under which there exist equilibria obeying the consumption-based capital asset pricing model. The paper also extends the equilibrium characterization of interest rates of Cox, Ingersoll, and Ross (1985) to multiagent...

Recent anti-trust cases exacerbated the concerns of investors regarding the effects of a firm’s monopoly power on its production choice, shareholder value, and the overall economy. We address this issue within a dynamic equilibrium model featuring a large monopolistic firm whose actions not...

Recent anti-trust cases exacerbated the concerns of investors regarding the effects of a firm's monopoly power on its production choice, shareholder value, and the overall economy. We address this issue within a dynamic equilibrium model featuring a large monopolistic firm whose actions not only...

This article develops a multi-period production model to examine the optimal dynamic behaviour of a large monopolistic value-maximizing firm that manipulates its valuation as well as the price of its output. In the pre-commitment equilibrium the firm's output and labour demand are decreased,...

We present a theory and experimental evidence on pricing and portfolio choices under asymmetric reasoning. We show that under asymmetric reasoning, prices do not reflect all (types of) reasoning. Some agents who observe prices that cannot be reconciled with their reasoning switch from perceiving...
