Recently, Jean Imbs and colleagues have claimed that much of the purchasing power parity puzzle can be explained by 'aggregation bias'. This paper re-examines aggregation bias. It clarifies the meaning of aggregation bias and its applica... SS Chen,C Engel - 《Pacific Economic Review》 被引...
AggregationRankI find evidence for an Engel curve rank of three in both historical and recent data within the context of polynomial Engel curves. The results have implications for specification and for aggregation of consumer demands.Dora L Costa...
In the in vivo experiments, Eng improved bone loss in ovariectomized mice.Conclusion: Our study found that Eng inhibited RANKL-induced osteoclast differentiation through multiple signaling pathways, including MAPKs, NF-魏B, and ROS aggregation. Furthermore, Eng improved bone loss in ovariectomized ...
However, because of the limited coverage of the ACCRA data, estimation has been restricted to a fairly high level of aggregation. While the price and total-expenditure elasticities obtained at this level are obviously of interest in their own right, one of the main findings with the CES data ...

This paper shows that such systems exist...
This produces foreign exchange transactions that play a central role in information aggregation, providing testable links between transaction flows, exchange rates, and future fundamentals. We test these links using data on all end-user currency trades received at Citibank over 6.5 years, a sample ...
