Inherited wealth creates a second distinguishing characteristic of individuals, in addition to earning abilities. We incorporate this fact into a model of optimal labor income taxation, with bequests motivated by joy of giving. We …nd that taxes on bequests or on inheritances allow further redistribution, if in the parent generation initial wealth and earning abilities are positively related. O...

Conventionally, linear and univariate time series models are broadly used in earning forecast. However, their forecasting accuracies are seriously limited without considering sufficient important factors. On the other hand, using more variables does not guarantee to obtain better forecasting accuracy and may cause inefficiency. The Multi-Objective Genetic Algorithms (MOGA) have been shown to be...

OBJECTIVE Hairdressers have a high incidence of occupational diseases, owing to excessive wet work and exposure to chemical substances. The objective of this study was to assess the prevalence of occupational diseases in a population of self-employed hairdressers, matched for age and sex with a control group of wage-earning hairdressers. METHOD A health questionnaire was administered to both ...

Our university course for non-majors (Biology 100) on the neurobiology of drug addiction was recently retooled for delivery at high schools around the state of Washington in order to engage younger students in the study of psychoactive drugs. Many of these students are earning both high school and university credits (dual-enrollment). This paper outlines the course design principles we used to ...

This article incorporates tax evasion into an optimum taxation framework with individuals di ering in earning abilities and initial wealth. We nd that despite the possibility of its evasion a tax on initial wealth should supplement the optimal nonlinear income tax, given a positive correlation between initial wealth and earning abilities. Further, even if income and initial wealth are taxed opt...

In this paper we build a spatial, aspiration-based model of learning in the context of Cournot oligopoly from which we want to explore the conditions that lead to the emergence of cooperation among rms. We consider an economy consisting of many identical duopolies; each duopoly is placed on a square of a torus. The duopolists are boundedly rational agents which adopt a very simple behavioural r...

islamic and iranian cities, both, east and west, know the physical monuments of islamic culture1 based on one of the features of the islamic cities. meanwhile, other religious centers, including tkaya, hosseiniyeh and hospice is not the case to considerate, while these elements cause to shape group behavior, strengthen social ties and strengthening of cultural integration, have always played a ...

in this paper, we study the boundedness and persistence of the solutions, the global stability of the unique positive equilibrium point and the rate of convergence of a solution that converges to the equilibrium $e=(bar{x}, bar{y})$ of the system of two difference equations of exponential form: begin{equation*} x_{n+1}=dfrac{a+e^{-(bx_n+cy_n)}}{d+bx_n+cy_n}, y_{n+1}=dfrac{a+e^{-(by_n+cx_n)}}{d+...
