We investigate what it means for one act to be more ambiguous than another. The question is evidently analogous to asking what makes one prospect riskier than another, but beliefs are neither objective nor representable by a unique probability. Our starting point is an abstract class of...

A plant has more flexibility in choosing among different technologies before undertaking an investment than after installing a specific machine. This paper argues that the irreversibility of factor intensity choice may play an important role in explaining the dynamics of investment in the...

In this paper, we introduce uncertainty of the labour productivity of women in a competitive model of wage determination. We demonstrate that more qualified women are then offered much lower wages than men at the equilibrium. This result is consistent with the glass ceiling hypothesis according...

In this paper we present a dynamic discrete-time model that allows to investigate the impact of risk-aversion in an oligopoly characterized by a homogeneous non-storable good, sticky prices and uncertainty. Our model nests the classical dynamic oligopoly model with sticky prices by Fershtman and...

We compare the Nash bargaining solution in a reinsurance syndicate to the competitive equilibrium allocation, focusing on uncertainty and risk aversion. Restricting attention to proportional reinsurance treaties, we find that, although these solution concepts are very different, one may just...

Economists and politicians in Sweden stated in the early 1990s that devaluations of the country's currency had lessened the external pressure on manufacturing and led to a delay in structural change and rationalizations. The theory of transformation pressure generalizes the idea that...

The theory of transformation pressure offers a uniquely Swedish perspective on the "productivity slowdown" of the 1970s and 1980s. One example of this theory can be found in an influential argument from the early 1990s which states that devaluations of the Swedish currency lessened the external...

We review and evaluate some recent contributions on the modeling of entrepreneurship within a neoclassical framework, analyzing how and to what extent the fundamental ingredients suggested in the social science literature were captured. We show how these approaches are important in stressing the...

The underlying model combines the proximity-concentration trade-off framework with the real option approach. In contrast to the latest trade models, uncertainty is introduced as a continuous phenomenon. Furthermore, the model contains the innovation of comparing two option values simultaneously....

Uncertainties as to future supply costs of nonrenewable natural resources, such as oil and gas, raise the issue of the choice of supply sources. In a perfectly deterministic world, an efficient use of multiple sources of supply requires that any given market exhausts the supply it can draw from...
