This paper analyses price competition under product differentiation when goods are defined in a two dimensional characteristic space, and consumers do not know which firm sells which quality. Equilibrium prices consist of two additive terms, which balance consumers’ relative valuation of...

We study optimal saving when incomes are certain and risk bears on consumption. A key finding is that, with CARA utility and additive uncertain consumption, or CRRA utility and multiplicative consumption, risk-averse individuals do not form precautionary saving as in the standard theory of...

This paper combines the adjustment costs hypothesis of Tobin’s q models with Malinvaud’s proposition that, irreversibility and uncertainty matter in explaining investment. Demand uncertainty and irreversibility allow for excess capacity and lead firms to look at the expected excess capacity...

Trigger values are derived for investment projects that are affected by (i) uncertainty (according to Dixit and Pindyck, 1994) and (ii) construction periods (see Majd and Pindyck, 1987). The values are compared theoretically with trigger values for projects with rather certain returns, as well...

In this paper we aim to understand how unemployment benefits may affect investment in education when the latter is characterized by uncertain returns. This is done in an overlapping generations model in which endogenous growth is introduced through human capital accumulation. We develop a...

In this paper, the public investment provision takes place in a stochastic environnement. The role of the government is to remove a part of the uncertainty faced by the firm. If the government simply maximizes the value of the firm, then the optimal tax is smaller under imperfect competition...

This paper investigates erapirically the influence of uncertainty on corporate investment. Uncertainty of demand, output prices and investment prices are measured by the standard deviation of (pre-)filtered Belgian (1984-1992) and Spanish (1983-1993) panel data, and included as explanatory...
