The theoretical literature on business cycles predicts a positive investment response to productivity improvements. In this work we question this prediction from theoretical and empirical standpoints. We fiÂ…rst show that a negative short-term response of investment to a positive technology...

Small firms encounter difficulties in raising external finance owing to greater information problems. For small innovative firms, whose activity is more difficult to evaluate, the cost of external finance could be even higher. This paper examines special features of the financial structure of...

The theoretical literature on business cycles predicts a positive investment response to productivity improvements, a prediction we question from theoretical and empirical perspectives. We show that a short-term negative response of investment to a positive technology shock is consistent with a...

Small firms encounter difficulties in collecting external finance due to greater information problems. For small innovative firms, whose activity is more difficult to evaluate, the cost of external finance could be even higher. This paper aims to shed light on special features in financial...

We present analytical investigations of a multiplicative stochastic process that models a simple investor dynamics in a random environment. The dynamics of the investor’s budget, x(t), depends on the stochasticity of the return on investment, r(t), for which different model assumptions are...

As the millennium draws to an end, the threat posed by the Year 2000 (Y2K) problem is inducing vast private and public spending on its remediation. In this paper, we model the Y2K problem as an anticipated, permanent loss in output whose magnitude can be lessened by investing resources in...
