An Incentive-Compatibility Approach to the Problem of Monitoring a Bureau

An incentive-compatibility framework for regulating a monopolist with unknown costs is applied to the sponsor’s problem of monitoring a bureau. Following Mueller (1989), the bureau does not make take-it-or-leave-it budget proposals to the sponsor. Rather, the bureau must announce a marginal cost per unit of output to the sponsor. Given that report, the sponsor chooses a price that it will pay to the bureau for each unit of output, and the sponsor chooses the level of output as well. The analysis reveals the price per unit of output that the sponsor must pay to the bureau to maximize social welfare.Bureaucracy; Administrative Processes in Public Organizations; Corruption; Asymmetric and Private Information; Incentive Compatibility; Monitoring

High-temperature molten salt thermal energy storage systems for solar applications

Alkali and alkaline earth carbonate latent-heat storage salts, metallic containment materials, and thermal conductivity enhancement materials were investigated to satisfy the high temperature (704 to 871 C) thermal energy storage requirements of advanced solar-thermal power generation concepts are described. Properties of the following six salts selected for compatibility studies are given: three pure carbonates, K2CO3, Li2CO3 and Na2CO3; two eutectic mixtures, BaCO3/Na2CO3 and K2CO3/NaCO3, and one off-eutectic mixture of Na2CO3/K2CO3

Is the NAIRU More Useful in Forecasting Inflation than the Natural Rate of Unemployment?

Recent studies have indicated that the terms 'NAIRU' (non-accelerating inflation rate of unemployment) and 'natural rate of unemployment' are not interchangeable. While NAIRU is an empirical macroeconomic relationship estimated via a Phillips curve, the natural rate is an equilibrium condition in the labour market, reflecting the market's microeconomic features. This study evaluates comparatively the inflation-forecasting power of alternative time-varying estimates of the natural rate of unemployment relative to the NAIRU. The natural rate of unemployment in the USA since the Second World War is estimated. Three alternative methods are utilized: the Kalman filter, a structural determinants approach, and the Hodrick-Prescott filter. The section that follows assesses how each estimator of the natural rate compares with the others - as well as with the NAIRU derived from a Phillips curve - in forecasting inflationary changes in the USA in the second half of the twentieth century. The analysis reveals that the overall inflation-forecasting utility of the natural rate of unemployment relative to the NAIRU is not very different. Moreover, the conclusion appears to be quite robust to various estimators of the natural rate.Employment, Unemployment, Wages, Intergenerational Income Distribution; Price Level, Inflation, Deflation; U.S.; Northern America; Inflation; Macroeconomics; NAIRU; Natural Rate; Phillips Curve; Unemployment

Spreading Academic Pay over Nine or Twelve Months: Economists Are Supposed to Know Better, but Do They Act Better?

Our paper empirically considers two general hypotheses related to the literature of behavioral economics. First, we test the null hypothesis that individuals behave, on average, in a manner more consistent with the rational expectations hypothesis than with the idea of self-control in the face of hyperbolic discounting in their saving decisions. Second, along a variety of dimensions, we examine whether individuals exhibit Herbert Simon’s notion that the goal formation of individuals will differ depending upon their relative levels of experience and knowledge. Perhaps there are significant differences among groups in their saving decisions that depend upon their apparent levels of intelligence, education, and knowledge. Finally, using a variety of individual-specific control variables, we test for robustness of the results.Consumer Economics, Empirical Analysis, Life Cycle Models and Saving

High-temperature molten salt thermal energy storage systems

The results of comparative screening studies of candidate molten carbonate salts as phase change materials (PCM) for advanced solar thermal energy storage applications at 540 to 870 C (1004 to 1600 F) and steam Rankine electric generation at 400 to 540 C (752 to 1004 F) are presented. Alkali carbonates are attractive as latent heat storage materials because of their relatively high storage capacity and thermal conductivity, low corrosivity, moderate cost, and safe and simple handling requirements. Salts were tested in 0.1 kWhr lab scale modules and evaluated on the basis of discharge heat flux, solidification temperature range, thermal cycling stability, and compatibility with containment materials. The feasibility of using a distributed network of high conductivity material to increase the heat flux through the layer of solidified salt was evaluated. The thermal performance of an 8 kWhr thermal energy storage (TES) module containing LiKCO3 remained very stable throughout 5650 hours and 130 charge/discharge cycles at 480 to 535 C (896 to 995 F). A TES utilization concept of an electrical generation peaking subsystem composed of a multistage condensing steam turbine and a TES subsystem with a separate power conversion loop was defined. Conceptual designs for a 100 MW sub e TES peaking system providing steam at 316 C, 427 C, and 454 C (600 F, 800 F, and 850 F) at 3.79 million Pa (550 psia) were developed and evaluated. Areas requiring further investigation have also been identified

Gain Modulation by Corticostriatal and Thalamostriatal Input Signals during Reward-Conditioned Behavior.

The cortex and thalamus send excitatory projections to the striatum, but little is known about how these inputs, either individually or collectively, regulate striatal dynamics during behavior. The lateral striatum receives overlapping input from the secondary motor cortex (M2), an area involved in licking, and the parafascicular thalamic nucleus (PF). Using neural recordings, together with optogenetic terminal inhibition, we examine the contribution of M2 and PF projections on medium spiny projection neuron (MSN) activity as mice performed an anticipatory licking task. Each input has a similar contribution to striatal activity. By comparing how suppressing single or multiple projections altered striatal activity, we find that cortical and thalamic input signals modulate MSN gain and that this effect is more pronounced in a temporally specific period of the task following the cue presentation. These results demonstrate that cortical and thalamic inputs synergistically regulate striatal output during reward-conditioned behavior

Simulated Tractor Chassis Suspension System

The development of a chassis suspension system for an agricultural tractor has been described to improve the operator ride comfort. Computer simulation tech-niques were used to formulate the tractor models and to compute the natural frequencies and frequency response of the models, as well as the RMS acceleration response, to evaluate the effect of the suspension system and cab position on operator ride comfort

An Analysis of the Services Offered to Cancer Patients in the State of Maine

People who are diagnosed with cancer should have access to information about their disease. These patients require the proper supportive care to meet their needs, and in order to do that; many people are turning to cancer support centers. These centers offer complementary and alternative medicine (CAM) such as yoga, meditation, reiki, support groups, etc. Cancer support centers have been developed that try to reach as many people as possible with their services. Maine is a very rural state so not everyone has easy access to complementary and alternative medicine practices, but these cancer support services can be found at various facilities throughout the state. Cancer support centers do everything that they can to make sure that patients and families affected by cancer receive high-quality information and support. In order to make sure that these centers are responsive to the needs of the people affected by the disease, I have conducted a study to determine what services the patients have found to be beneficial. One hundred and twenty two participants took the survey. Survey participants found a majority of the services listed to be beneficial to their health. Exercise/fitness group was the most beneficial and hypnosis was the least beneficial. Common themes came up in the survey that included topics such as the need for more support centers and less traveling for members
