This paper examines a model of optimal growth where the agregation of two separate well behaved and concave production technologies exhibits a basic non-convexity. Multiple equilibria prevail in an intermediate range of interest rate. However, we show that the optimal paths monotonically...

In a simple formal model of two-country, two-good with an elementary Conflict Technology, we use a rudimentary game theoretics to study the matter of war and peace, where under peace, cooperative exchange takes place, and where, in case of war, the winner takes all through appropriation of the...

In order to reach the state of economic sustainability, the problem of technology transition emphasizes the possibility of substituting for the exhaustible resource with an everlasting source of energy input. This paper aims at providing an analysis of this problem in an overlapping-generation...

Consider a small developing economy with a manufacturing sector opened to international trade, and an agricultural sector having limited, not to say any, access to world markets. We modify the Grossman and Helpman's influence-driven model of trade policy formation to allow for an endogenously...

We propose a model where the benevolent resource planner's management is endogenous. This allows for the analysis of trade models with management régimes other than the polar open access and 1st best régimes. Interestingly, 2nd best, endogenous, management régimes are more realistic than the...

We consider a firm that must undergo a costly and time-consuming regulatory process before making an irreversible, lagged investment whose value varies randomly. We analyze two cases: regulatory approval is valid forever or it expires after some time. We apply our model to Hydro-Québec's...

Models use for natural resources prices usually preclude the possibility of large changes (jumps) resulting from discrete, unexpected events. To test for the presence of jumps and ARCH effects, we propose to use bounds and bootstrap test techniques, thus solving the unidentified nuisance...

Empirical research on oil price dynamics for modeling and forecasting purposes has brought forth several unsettled issues. Indeed, statistical support is claimed for various models of price paths, yet many of the competing models differ importantly with respect to their fundamental temporal...

We studied the protectionist character of a minimum quality standard (MQS). We show that in the fixed cost model where two firms, one local and one foreign, compete in a local market, the implementation of a MQS on the local market is a protectionist political only if the local firm supplies the...

L'évolution de la consommation d'énergie entre deux périodes peut être décomposée de manière à souligner les rôles joués par le niveau d'activité économique, le changement structurel à l'intérieur du secteur étudié, les conditions climatiques et l'efficacité énergétique. Nous...
