The logic behind this is derived from a theory called ricardian equivalence , which holds that government spending cannot boost demand , since consumers cut their own expenditure in anticipation of higher taxes ahead .
So far , dr murphy told the conference , these experiments have merely confirmed the equivalence principle to one part in 10 trillion .
murphy博士在会议上说,迄今为止,这些实验仅仅是在10万亿分之一的概率上证实了等效原理。
If the equivalence principle were violated , the moon 's orbit around the earth would appear skewed , either towards or away from the sun .
如果等效原理遭到违背,月球围绕地球公转的轨道将会出现偏斜靠近或是远离了太阳。
Albert einstein stands in front of the annual meeting of the american mathematical society and the american association for the advancement of science , attempting to address a problem that he had pondered for decades-that of the equivalence of energy and inertial mass in reference to his theory of special relativity .
Some believe that the shifts in private sector balances in post-bubble countries are caused by fiscal deficits , either because of " ricardian equivalence " the view that people increase savings in response to the higher deficits or because of " crowding out " of spending by the deficits .
The new system uses a calculation based on the energy equivalence of electricity .
新体系采用了一种基于电能能源等效的计算方法。
In fact , under some strict assumptions , the revenue equivalence theorem ( also due to vickrey ) states that all four auction types will result in an identical level of revenue to the seller .
