One of the main resonator factors in watershed soil erosion is inappropriateland management including conversion of pasture land to dry-land farming.Unfortunately, the changes of Gara Su watershed usages have been very common.Thus, in order to understand the influence of land use on runoff rate and soil loss, soillosses were investigated and determined under both pasture and dry-land agricultur...

The two primary approaches to estimate marginal willingness-to-pay (MWTP) are hedonic (Rosen, 1974) and discrete choice models (McFadden, 1974). This paper provides a tractable framework to investigate the relationship between MWTP in these models. By deriving the hedonic price gradient implicitly from the share function in the discrete choice model, I present an analytical mapping between the ...

Incentivized experiments are commonly used to estimate marginal rates of intertemporal substitution (MRS) in the lab and in the field in order to make inferences about individual time preferences. This paper considers an integrated model of behavior in which individuals are subject to financial shocks and credit constraints, and take those into account when making experimental choices. The mode...

We report a laboratory experiment that enables us to distinguish preferences for altruism (concerning tradeoffs between own payoffs and the payoffs of others) from social preferences (concerning tradeoffs between the payoffs of others). By using graphical representations of three-person Dictator Games that vary the relative prices of giving, we generate a very rich data set well-suited to study...

The increasing body of evidence from high income countries linking pollution to health outcomes (Ken Chay and Michael Greenstone 2003; Janet Currie and Matthew Neidell 2004), has raised concerns about the health impact of adverse air quality in developing countries, where, in general, environmental regulation is less stringent and health monitoring and treatment are less accessible. These conce...

This study uses a new data set which merges the Social Security earnings histories of parents and children in the 1984 Survey of Income and Program Participation to measure the intergenerational elasticity in earnings in the United States. Earlier studies that found an intergenerational elasticity of 0.4 have typically used only five year averages of fathers’ earnings to measure fathers’ perman...

We utilize graphical representations of Dictator Games which generate rich individual-level data. Our baseline experiment employs budget sets over feasible payoff-pairs. We test these data for consistency with utility maximization, and we recover the underlying preferences ∗The results reported here were previously distributed in three different papers titled “Individual Preferences for Giving,...

AND MOTIVATION Many examples exist in nature where the output of a dynamic system is a spiky time series. Well known examples of such systems include the Rössler system [1], which was developed to model the Earth’s magnetic field, the Hindmarsh-Rose [2, 3] system which has been proposed to model neuron membrane electrical activity, Chay-Keizer equations which model pancreatic cells, and many ot...
