We consider a supply chain involving one supplier and one retailer in which a revenuesharing contract is adopted. Under this contract, the retailer can obtain the product from the supplier at a discounted price. As a compensation, the retailer must share his revenue with the supplier at a certain revenue-sharing rate, say r (0 ≤ r ≤ 1), where r represents the portion of the revenue to be kept b...

Incidence of cholera outbreak is a serious issue in underdeveloped and developing countries. In Zimbabwe, after the massive outbreak in 2008-09, cholera cases and deaths are reported every year from some provinces. Substantial number of reported cholera cases in some provinces during and after the epidemic in 2008-09 indicates a plausible presence of seasonality in cholera incidence in those re...

In comparison to the other continents where rabies is endemic, the history of rabies in Africa before the 19 th century, is rather fragmentary and largely anecdotal. There are no definite reports to indicate that rabies was present in Zimbabwe before 1902, although Edmonds (as cited by Foggin, 1988 and Swanepoel et al., 1993) reports anecdotal evidence from older members of the population who c...

This paper outlines how the theory of contests is applied to professional team sports leagues. In the first part, we present the traditional Tullock contest and explain some basic properties of the equilibrium. We will then extend this static contest to a two-period model in order to analyze dynamic aspects of contests. In the second part, we will present applications of contest theory in sport...

Although fiscal policies of central governments sometimes provide modest insurance against regional income shocks, this paper shows that procyclical fiscal policy among provincial governments can easily overwhelm these stabilizing effects. We examine the cyclicality of budget items among provincial governments in seven federations, showing that own-source taxes are generally highly procyclical,...

The paper establishes a supply chain coordinating model based on single 4PL-multy 3PL. Considering goods loss and damage, it comes to the conclusion that the fixed revenue-sharing contract couldn't be coordination when the yields was relative to the efforts of 3PL and 4PL. In order to get the coordination, we first model a fixed revenue-sharing contract based on side payment using L-F model and...
