Why Higher Real Wages May Reduce Altruism for the Poor

The non-poor need to have information on the existence and the cause of the plight of the poor for redistribution to be a public good. Since gaining this information takes time, the full price of helping the poor includes both the money cost and the time involved in empathizing. Over the last century, the higher real incomes of the poor have reduced the manifestations of poverty. When poverty is less obvious, the non-poor are not as aware of poverty. This article also discusses when redistribution is most likely to be a public good.Altruism; Wage

Costs of adjustment to climate change

The present paper argues that the costs of climate change are primarily adjustment costs. The central result is that climate change will reduce welfare whenever it occurs more rapidly than the rate at which capital stocks (interpreted broadly to include natural resource stocks) would naturally adjust through market processes. The costs of climate change can be large even when lands are close to their climatic optimum, or evenly distributed both above and below that optimum.Environmental Economics and Policy,

Data catalog series for space science and applications flight missions. Volume 3B: Descriptions of data sets from low- and medium-altitude scientific spacecraft and investigations

The main purpose of the data catalog series is to provide descriptive references to data generated by space science flight missions. The data sets described include all of the actual holdings of the Space Science Data Center (NSSDC), all data sets for which direct contact information is available, and some data collections held and serviced by foreign investigators, NASA and other U.S. government agencies. This volume contains narrative descriptions of data sets from low and medium altitude scientific spacecraft and investigations. The following spacecraft series are included: Mariner, Pioneer, Pioneer Venus, Venera, Viking, Voyager, and Helios. Separate indexes to the planetary and interplanetary missions are also provided

GETTING THE MOST FOR OUR MONEY IN FARMLAND PRESERVATION

This paper looks at the design and operation of the main program in Maryland, the Maryland Agricultural Land Preservation Fund (MALPF). We examine the features of the program in comparison to possible alternative designs. Our broader purpose is to examine the nature of farmland preservation and the implications for how to best design farmland preservation programs.Agricultural and Food Policy,

DIMINISHING MARGINAL VALUE

The notion of diminishing marginal value has had a profound impact on the development of neoclassical theory. Early neoclassical scholars had considerable difficulty convincing contemporaries of the new paradigm's value until political economists, including Jevons and Walras, used the critical assumption of diminishing marginal value to link utility and demand. While diminishing marginal value remains a key component of modern economic intuition, there is surprisingly little empirical verification of its existence or level. This paper gathers field data across a myriad of subject pools--from undergraduate students to PTA members to sportscard enthusiasts--to examine several aspects of preferences in both price and exchange institutions. Examining behavior of nearly 900 subjects across several treatments, we find strong evidence of diminishing marginal value.Research Methods/ Statistical Methods,

Econometrics: A Bird’s Eye View

As a unified discipline, econometrics is still relatively young and has been transforming and expanding very rapidly over the past few decades. Major advances have taken place in the analysis of cross sectional data by means of semi-parametric and non-parametric techniques. Heterogeneity of economic relations across individuals, firms and industries is increasingly acknowledged and attempts have been made to take them into account either by integrating out their effects or by modeling the sources of heterogeneity when suitable panel data exists. The counterfactual considerations that underlie policy analysis and treatment evaluation have been given a more satisfactory foundation. New time series econometric techniques have been developed and employed extensively in the areas of macroeconometrics and finance. Non-linear econometric techniques are used increasingly in the analysis of cross section and time series observations. Applications of Bayesian techniques to econometric problems have been given new impetus largely thanks to advances in computer power and computational techniques. The use of Bayesian techniques have in turn provided the investigators with a unifying framework where the tasks of forecasting, decision making, model evaluation and learning can be considered as parts of the same interactive and iterative process; thus paving the way for establishing the foundation of “real time econometrics”. This paper attempts to provide an overview of some of these developments.history of econometrics, microeconometrics, macroeconometrics, Bayesian econometrics, nonparametric and semi-parametric analysis

"No-Till" Farming Is a Growing Practice

Most U.S. farmers prepare their soil for seeding and weed and pest control through tillage—plowing operations that disturb the soil. Tillage practices affect soil carbon, water pollution, and farmers’ energy and pesticide use, and therefore data on tillage can be valuable for understanding the practice’s role in reaching climate and other environmental goals. In order to help policymakers and other interested parties better understand U.S. tillage practices and, especially, those practices’ potential contribution to climate-change efforts, ERS researchers compiled data from the Agricultural Resource Management Survey and the National Resources Inventory-Conservation Effects Assessment Project’s Cropland Survey. The data show that approximately 35.5 percent of U.S. cropland planted to eight major crops, or 88 million acres, had no tillage operations in 2009.Tillage, no-till, Agricultural Resource Management Survey, ARMS, U.S. crop practices, National Resources Inventory-Conservation Effects Assessment Project, NRI-CEAP, carbon baseline, carbon sequestration, Environmental Economics and Policy, Farm Management, Land Economics/Use, Resource /Energy Economics and Policy, Risk and Uncertainty,

A Test of Competing Explanations of Compensation Demanded

The disparity between willingness-to-pay and willingness-to-accept, also known as compensation demanded, is a robust experimental finding. Two types of explanations been proposed. The first invokes psychological effects, broadly categorized as reference dependence and loss aversion. The second explanation is that there are large substitution effects but that underlying behavior is neoclassically utility-theoretic. The key observation motivating the present study is that loss aversion implies concavity of willingness to accept, whereas the utility-theoretic explanation implies convexity. We report experiments in which subjects were endowed with 3 items and asked the minimum payments they required to be willing to relinquish 1, 2, or 3 of them. We examine whether the compensation demanded is convex, concave, neither, or both in the number of items being relinquished

The Effects of Hypergravic Fields on Neural Signalling in the Hippocampus

The goal of this grant is to study the effect of hypergravic fields on the modulation of hippocampal electrical activity by serotonin (5-HT). The proposed study represents a shift from our previous NASA grants covering three diverse areas in neurobiology (thermoregulation, vestibular and auditory brainstem evoked responses, and the hippocampus) to consideration of only one of these areas, the hippocampus. To place our proposed hippocampal experiments in context with relevant Spacelab-3 experiments and hypergravic experiments, two experiments on receptor changes in animals exposed to altered gravitational fields are first described. Our experiments build on these structural/biochemical observations and extend investigations to related electrical activity at 1 G and in hypergravic fields. The background continues with a review of past studies at 1G related to effects of serotonin on hippocampal electrical activity (i.e., population spikes, intracellular potentials)
