The management of natural commons is typically subject to threshold effects: past a certain agregate consumption level, the benefits of the commons will be lost for everybody. As dealing with the global climate illustrates, moreover, it is often impossible to locate an actual threshold with...

We study the effect of changing income on optimal decisions in the multidimensional expected utility framework with strongly separable preferences. Using the Kihlstrom and Mirman (1974) (KM) utility representation, we show that the effect of changing income can be decomposed into a modified...

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...

A key element of government is to uphold law and order. This paper will evaluate the impact of slow judiciaries on entrepreneurship. In 2002 a judicial reform was implemented in 6 of Pakistan's 117 districts to facilitate rapid case disposal. Drawing on a panel dataset of 875 district judges'...

We study the effect of heterogeneous growth in demand on resource extraction. Using the Great Fish War framework of Levhari and Mirman (1980), we show that heterogeneity in demand growth has a profound effect on both cooperative (Cournot-Nash and Stackelberg) and cooperative solutions

We explain the persistence of low performances in African agriculture by analyzing the determinants of farmers' decisions to modernize their farming practices. Owing to sociocultural factors specific to Sub-Saharan Africa, farmers' decisions on farming practices are strategic complements. We...

We estimate the impact of exchange rate fluctuations and other external factors on hours worked and employment in Canada's manufacturing industries. The analysis is based on a dynamic model of labour demand and the econometric strategy employs a dynamic OLS approach for cointegrating...

We address the issue of risk aversion in a competitive equilibrium when some buyers engage in learning and information is conveyed through the price system. Specifically, since the learning process yields uncertainty, we study the effect of risk aversion on the equilibrium outcomes of the model,...

We study learning in perfect competition. A price-taking firm sells a good whose quality is unknown to some buyers. The uninformed buyers use the price to infer information about quality. The presence of noise on the supply prevents perfect learning. Even though the firm is a price-taker,...

We study third-degree price discrimination in the presence of uninformed buyers who extract noisy information from observing prices. In a noisy learning environment, price discrimination can be detrimental to the firm and beneficial to the consumers. On the one hand, discriminatory pricing...
