新古典派経済学理論の三大前提条件、即ち完全競争、情報の対称性、行為者の合理性のうち、最後の前提条件は、経済学以外の分野からの批判はあっても、経済学自身の側からの批判はなかった。2002年のアルフレッド・ノーベル記念経済学スウェーデン銀行賞受賞者の一人、ダニエル・カーネマンは一貫して経済行為者の非合理性に関する理論を提唱し、彼の理論を裏付ける実験を行ってきた。カーネマンによれば経済行為は合理性よりも直感に依拠する場合が多いという。本論文はカーネマンの理論と実験の内容を短くレヴィユーした後、カーネマンの見解を直近の脳科学(neuroscience)、特にジェラルド・エーデルマンによって提唱されている神経細胞群選択説を参考にしつつ、吟味するものである。

Market price is, as Amartya Sen points out, institutional while the prices through which consumer expresses his preference are conceptual. Thus, price may be inadequate as a weight to aggregate goods to measure income when income is used as a yardstick of welfare. Traditionally, economics regards itself as a social science dealing with goods and services. However, economics does not analyze goods and services but only services. Only services are exchanged in the market and physical goods are mere vehicles of services. Material balance approach vis-a-vis traditional market value balance approach will more sharply shed light on the waste problems.

In a utility interactive photovoltaic (PV) generating system, a PWM inverter is used for the connection between the PV arrays and the utility. The inverter is controlled to keep the output power at the maximum point for the PV. Although the PV power can be easily found by using the measured PV voltage and PV current, the installation of two detectors in the system is indispensable to obtain the exact PV power. In the system operation with the maximum power which is fed into the utility, the PV does not always operate at the maximum point of the PV output power because of the power losses in the system. It has been reported that the use of the measured ac voltage or ac current in the inverter output side can exclude the system losses from consideration and achieve the system operation with the maximum utility power. In this manner, however, since the ac output waveforms of the PWM inverter consist of many pulse trains, the filter circuit may be necessary for the detector to get the exact values of the ac output.This paper proposes a calculation method of the utility power in the PV generating system by using a PWM current source inverter. In this system, the PV current only is measured and is employed for the power calculation combining the control parameter of the PWM inverter. As the proposed manner monitors the utility power instead of the PV power, the control which does not need to take the system losses into consideration can be achieved. This paper presents the calculation method of the power for the single-phase inverter-PV system and gives the experimental basic characteristics. Moreover, the application of the proposed manner to the three-phase PWM inverter-PV system is shown and the experimental results are given.
