In this paper I attempt to investigate the role of governance - as measured by government effectiveness, control of corruption, and rule of law - on the HIV prevalence. Thus, the paper argues that countries whose governments are highly ranked according to these various indices of the quality of...

Intervention policies for HIV/AIDS differ in their approaches, and acceptability to control the spread of the epidemics. We introduce a theoretical model to depict how several factors may determine an individual's maximum willingness to pay for any HIV/AIDS policy. Heterogeneous baseline risks,...

This paper proposes an alternative to standard cardinal tournaments. The analysis contrasts "hybrid" cardinal tournaments to standard cardinal tournaments and piece rates. It shows that providing for partial insurance against common uncertainty via a hybrid tournament (in which the weights on...

We adapt a genetic-based learning classifier system to a forecast evaluation exercise by making its key parameters endogenous and taking into account the need of convergence of the learning algorithm, an issue usually neglected in the literature. Doing so, we find it hard for the algorithm to...

This note shows that there exists a threshold level of optimal prevention for a risk neutral agent which separates cases where a risk averse agent exerts less effort in prevention than a risk neutral agent and cases where she exerts more effort. We also show that the risk averse agent makes...

This paper proposes a novel method of global optimization based on host-parasite co-evolution. It also develops a Fortran-77 code for the algorithm. The algorithm has been tested on 100 benchmark functions (of which the results of 32 relatively harder problems have been reported). In its search...

According to an early approach, the decision to trust in the one-shot anonymous trust game is intuitively tantamount to a risky decision: the willingness to bet on the reciprocation of my investment. In a seminal study, Eckel and Wilson (2004) explored the correlation between risk attitudes (as...

We correct an analysis by Isik (2004) regarding the effects of uncertainty on the WTA-WTP gap. Isik presents as his primary result a proposition that the introduction of uncertainty regarding environmental quality improvements causes WTA to increase and WTP to decrease by identical amounts...

This paper analyzes the value of menus of contracts in a context of delegated expertise with nondelegated decision making. Firms delegate to managers the task of obtaining information about strategic decisions, and they choose whether or not to delegate the actual decision-making process to...
