A principal sequentially delegates project adoption decisions to an agent, who can assess project quality but has lower standards than the principal. In equilibrium, the principal allows bad projects in the future to incentivize the agent to be selective today. The optimal contract, termed Dynamic Capital Budgeting, comprises two regimes. First, the principal provides an expense account to fund...

Resumen. En este trabajo se presenta la śıntesis de un mecanismo de cuatro barras para seguimiento de una trayectoria lineal de seis puntos. Para resolver el problema de optimización numérica con restricciones asociado al mecanismo se utiliza el algoritmo de evolución diferencial, modificado para aplicar una selección tipo torneo basada en las reglas de factibilidad de Deb. Los resultados alcan...

Kalyanmoy Deb and Samir Agrawal Kanpur Genetic Algorithms Laboratory (KanGAL), Department of Mechanical Engineering, Indian Institute of Technology Kanpur, PIN 208 016, India E-mail: deb,samira @iitk.ac.in Abstract Most applications of genetic algorithms (GAs) in handling constraints use a straightforward penalty function method. Such techniques involve penalty parameters which must be set righ...

A large number of different Pseudo-R measures for some common limited 2 dependent variable models are surveyed. Measures include those based solely on the maximized likelihoods with and without the restriction that slope coefficients are zero, those which require further calculations based on parameter estimates of the coefficients and variances and those that are based solely on whether the qu...

As the first step in developing an optimal foraging model for moose (Belovsky 1978), a time-energy budget for a moose was developed. For the summer period (late May through early September) at Isle Royale National Park, Michigan, we made various behavioral observations on feeding moose and inventoried their food resources. Employing these various sets of data, we were able to determine the quan...

Our paper documents that land-use change impacts regional and global climate through the surface-energy budget, as well as through the carbon cycle. The surface-energy budget effects may be more important than the carbon-cycle effects. However, land-use impacts on climate cannot be adequately quantified with the usual metric of 'global warming potential'. A new metric is needed to quantify the ...

Suppose an agency awards a ...xed number of prizes to applicants in di¤erent categories such that the applicant-to-winner ratio is constant by category. It is demonstrated in a simple theoretical model that the number of awards in a category will typically be positively related to the degree of applicant uncertainty. The theoretical ...ndings are related to awards data from the Social Sciences ...
