The aim of this paper is to propose a model of decision-making for lotteries. The key element of the theory is the use of lottery qualities. Qualities allow the derivation of optimal decision-making processes and are taken explicitly into account for lottery evaluation. Our contribution explains...

We propose to analyse the hyperbolic discounting preferences effect on the innovator's research investment decision. Investing in research allows him to acquire information, and then to reduce the uncertainty of the risks of his project. We find that whatever the innovator's preferences, that is...

We study the effect of dynamic and investment externalities in a one-sector growth model. In our model, two agents interact strategically in the utilization of capital for consumption, savings, and investment in technical progress. We consider two types of investment choices: complements and...

Do investment models fit firm-level data? - which model fits best? To answer this question we estimate alternative models using Compustat data. We find that both a version of the Hayashi (1982) and a model with decreasing returns to scale in production fit firm-level data very well. Our...

It has long been recognized that the quality of property rights greatly impacts the economic development of a country and the use of its natural resources. Since Long (1975), the conventional wisdom has been that ownership risk induces a firm to overuse the stock of a resource. However, the...

Empirical studies point to trade credit as an important continuing source of short term financing for small and medium-sized enterprises. We show that vendor financing appears in equilibrium as the result of repeated trade interactions between a buyer and a supplier when changing supplier is...

In a first for South Africa, we draw on literature on infrastructure productivity to model dynamic economywide employment impacts of infrastructure investment funded with different fiscal tools. According to the South African investment plan, the policy will affect the stock of infrastructure as...

We generalize the classical expected-utility criterion by weakening transitivity to Suzumura consistency. In the absence of full transitivity, reflexivity and completeness no longer follow as a consequence of the system of axioms employed and a richer class of rankings of probability...
