We analyse the consumption strategy of a dynamically inconsistent individual for goods that provide an immediate benefit and a delayed cost. The agent has incomplete information on the cost inherent to each unit of consumption and partially learns this value anytime he consumes. We show that, by...

This paper reconsiders the theory of existence of efficient allocations and equilibria when consumption sets are unbounded below under the assumption that agents have incomplete preferences. Our model is motivated by an example in the theory of assets with short-selling where there is risk and...

The theory of existence of equilibrium with short-selling is reconsidered under risk and ambiguity modelled by risk averse variational preferences. No-arbitrage conditions are given in terms of risk adjusted priors. A sufficient condition for existence of efficient allocations is the overlapping...

The theory of existence of equilibrium with short-selling is reconsidered under risk and ambiguity modelled by risk averse variational preferences. A sufficient condition for existence of efficient allocations is that the relative interiors of the risk adjusted sets of expectations overlap. This...

We analyze bubbles and crashes in a model in which some investors are partially sophisticated. While the expectations of such investors are endogenously determined in equilibrium, these are based on a coarse understanding of the market dynamics. We highlight how such investors may endogenously...

The present paper draws on the main issues in the production of scientific knowledge based upon grounded theory in management accounting research. This piece of work is a bibliographic study confronting grounded theory practices with the expectations of its founders (Glaser et Strauss, 1967; Strauss...

Multinational enterprises (MNEs) develop their networks of foreign affiliates gradually over time. Instead of exploring all profitable opportunities immediately, they first establish themselves in their home countries and then enter new markets stepwise. We argue that this behavior is driven by...

We introduce learning into a Hotelling model of a non-renewable resource market. By combining learning and scarcity we add significantly to the dynamics implied by learning and substantially enhance the volatility of commodity prices. In our learning model we show how a self confirming...

A group of P identical managers has to make a choice between N alternatives. They benefit from reaching the decision quickly. In order to learn which is the best option, the alternatives have to be compared. A manager is able to identify the better one of two alternatives only with a certain...
