For a continuous-time financial market with a single agent, we establish equilibrium pricing formulae under the assumption that the dividends follow an exponential Lévy process. The agent is allowed to consume a lump at the terminal date; before that, only flow consumption is allowed. The...

The paradox of the Stop-Loss-Start-Gain trading strategy is resolved by showing that along the hyperfinite timeline the strategy incurs infinitesimal losses summing up to a non-infinitesimal amount. As a consequence, the Black–Scholes formula is derived using only hyperreal arithmetic and...

In a two-period pure exchange economy with financial assets, a temporary financial equilibrium is an equilibrium of the current spot and security markets given forecast functions of future prices and payoffs. The temporary equilibrium model can then be interpreted as an Arrow-Debreu economy...

This paper explores the role of portfolio constraints in generating multiplicity of equilibrium. We present a simple financial market economy with two goods and two households, households who face constraints on their ability to take unbounded positions in risky stocks. Absent such constraints,...

This note identifies and fixes a minor gap in Proposition 1 in Barberis and Huang (Am Econ Rev 98(5):2066–2100, <CitationRef CitationID="CR2">2008</CitationRef>). Assuming homogeneous cumulative prospect theory decision makers, we show that CAPM is a necessary (though not sufficient) condition that must hold in equilibrium. We support...</citationref>

We consider a single-period financial market model with normally distributed returns and the presence of heterogeneous agents. Specifically, some investors are classical Expected Utility Maximizers whereas some others follow Cumulative Prospect Theory. Using well-known functional forms for the...

This note identifies and fixes a minor gap in Proposition 1 in Barberis and Huang (2008). Assuming homogeneous Cumulative Prospect Theory decision makers, we show that CAPM is a necessary (though not sufficient) condition that must hold in equilibrium. We support our result with numerical...

This paper presents the results of an empirical test of the capital asset pricing model (CAPM) on the returns on Philippine common stocks from 1990 to 2000. The test uses the two-step cross sectional regression (CSR) procedure to compute for the beta of each asset and the parameters of the...
