This article explores the behavior of the stock market in Colombia with the information given by the Bolsa de Bogota Index (Indice de la Bolsa de Bogota, IBB). The index is analyzed from January, 1930 to December, 1998. The inflation rate covers the same period; the inflation rate as measured by...

The neoclassical q-theory is a good start to understand the cross section of returns. Under constant return to scale, stock returns equal levered investment returns that are tied directly with characteristics. This equation generates the relations of average returns with book-to-market,...

We use a fully-specified neoclassical model augmented with costly external equity as a laboratory to study the relations between stock returns and equity financing decisions. Simulations show that the model can simultaneously and in many cases quantitatively reproduce: procyclical equity issuance;...

Investment-based asset pricing uses the link between stock and investment returns to tie expected returns with firm characteristics. I derive the equivalence between these two returns in the Q-framework with variable capacity utilization, proportional operating costs, irreversible investment,...

In this paper we derive a general formula for the cost of capital of government's claim (rg). Given our valuation framework that distinguishes three claimholders-equity holders, debt holders and government-we show for the models used in Myers (1974), Miles and Ezzell (1980) and Harris and...

The q-theory implies that investment is a first-order determinant of the cross section of expected returns, and that optimal investment drives the external financing anomalies. Our neoclassical model simultaneously and in many cases quantitatively reproduces: Procyclical equity issuance waves;...

More financially constrained firms are riskier and earn higher expected returns than less financially constrained firms, although this effect can be subsumed by size and book-to-market. Further, because the stochastic discount factor makes capital investment more procyclical, financial...

Equity risk premiums are a central component of every risk and return model in finance and are a key input into estimating costs of equity and capital in both corporate finance and valuation. Given their importance, it is surprising how haphazard the estimation of equity risk premiums remains in...

Mehra and Prescott (1985) argued that, according to sensible asset pricing models, stocks should provide at most a 0.35% premium over bills. However, companies use higher equity premia (average around 6%) for evaluating their investment projects, professors use in class and in their textbooks...
