This paper provides an alternative real options framework to assess how firms' strategic interaction under imperfect competition a¤ects the industrial dynamics of investment, concentration, and expected returns. When firms have similar production technologies, the cross sectional variation in...

The analysis of many complex problems and complex dynamic systems suggests that there are dependencies between high complexity and properties of the underlying structures, as the existence of large grids, non-regularities and inhomogeneous structures and irregular flows of information. These...

This paper extends the well known Capital Asset Pricing Model by Sharpe and Lintner to a multi-period context with possibly price dependent preferences. The model is built from individual forward looking agents adopting a portfolio selection scheme similar to the portfolio selection theory...

We investigate portfolio allocations and asset returns within a stochastic OLG economy with risky equity, generation-wide labor income shocks and portfolio nonnegativity constraints. Our model assumes a difference stationary endowment process, a young generation that faces labor income...

We consider a general equilibrium Lucas (1978) economy with one consumption good and two heterogeneous Epstein-Zin investors. The output is subject to rare large drops or, more generally, can have non-lognormal distribution with higher cumulants. The heterogeneity in preferences generates excess...

Allowing for a richer information structure than usual, we show that rational traders’ calculation with short-term price fluctuations may heavily influence their behaviour even if the interim price is not influenced by non-rational agents i.e. there is no noise trader risk. Instead, traders...

Contrary to the classic framework of passive strategies, if investors exploit return predictability through active strategies then there is a tension between the mean-variance frontiers that drive empirical work and the mean-variance preferences that are used in finance theory. We show that...

We show that the level of interest rates determines the magnitude of mispricing at the turn of the tax year, as investors face the trade-o¤ between selling a temporarily depressed stock this year and selling next year, but delaying tax implications by one year. Interest rates do explain the...
