ENVIRONMENTAL IMPACTS ON THE POPULATION DYNAMICS OF A TROPICAL SEABIRD IN THE CONTEXT OF CLIMATE CHANGE: IMPROVING INFERENCE THROUGH HIERARCHICAL MODELING

2011
Toshitaka Fukiharu

A primitive economic model with classical population theory is constructed in order to examine the greenhouse effect on the sustainability of human population as well as the environmental tax when the sustainability is in danger. The conclusion of this paper is that when the negative effect is small, the tax can guarantee the sustainability, where the effective tax rate interval for the sustain...

T he United Nations’ Millennium Development Goals, established in 2000, include the following: “Make available the benefits of new technologies—especially information and communications technologies.” A majority of technology’s benefits have been concentrated in industrialized nations and therefore limited to a fraction of the world’s population. The authors believe that technology has a large ...

In this paper we attempt to (i) extend the competitive equilibrium neoclassical growth model to incorporate consumer preferences that feature temptation and selfcontrol as in the framework developed by Gul and Pesendorfer; (ii) use the model to analyze taxation and welfare; and (iii) extend and specialize the Gul-Pesendorfer temptation formulation to be dynamic and, in particular, quasi-geometr...

It is essential to know the actual level of this standard of living, and whether it is improving or deteriorating. There can be two types of standards of living. One is the standard of living of the society as a whole, and the other is the standard of a group within the s...

Absentee voting is becoming more prevalent throughout the United States. Although there has been some research focused on who votes by absentee ballot, little research has considered another important question about absentee voting: which absentee ballots are counted and which are not? Research in the wake of the 2000 presidential election has studied the problem of uncounted ballots for precin...

Kandori, M., Mailath, G., Rob, R. [(1993), Learning, mutation, and long run equilibria in games, Econometrica 61, 29–56] (hereafter KMR) showed that a risk-dominant equilibrium is selected as a long run equilibrium in a symmetric 2 3 2 coordination game. But a risk-dominant equilibrium and a long run equilibrium exactly coincide only in the case of a large (infinite) population. In this paper w...

This paper attempts to explain the nature of recurrent famine, not just as a result of a series of adventitious effects, but more importantly as the unintended outcome of an exclusionary growth model. This adventitious effects matter a great deal, but their impact can only be understood in the light of the inherent weakness of the growth model, which impoverished the peasantry and hence generat...
