This paper addresses the web service composition problem considering multi-criteria regarding quality of services (QoS). Three different scenarios of multi-criteria mathematical programming models are explored under the framework of network based analysis in web service composition. This work...

We study the link between price points and price rigidity using two data sets: weekly scanner data and Internet data. We find that “9” is the most frequent ending for the penny, dime, dollar, and ten-dollar digits; the most common price changes are those that keep the price endings at...

We study the link between price points and price rigidity, using two datasets - weekly scanner data and Internet data. We find that (i) 9 is the most frequently used price-ending for the penny, dime, dollar, and ten-dollar digits, (ii) the most common price changes are those that keep the price...

We offer new evidence on the link between price points and price rigidity using two datasets. One is a large weekly transaction price dataset, covering 29 product categories over an eight-year period from a large U.S. supermarket chain. The other is from the Internet, and includes daily prices...

We study the link between price points and price rigidity, using two datasets containing over 100 million observations. We find that (i) 9 is the most frequently used price-ending for the penny, dime, dollar and ten-dollar digits, (ii) 9-ending prices are between 24%-73% less likely to change in...

This article examines the paradox that a supermajority rule in a legislature promotes excessive government spending. We propose a simple conjecture: If rent-seeking coalitions dominate legislative politics and if individual legislators' demands for rent-seeking activities are price-inelastic, a...

The “commodity currency†literature highlights the robust exchange rate response to fluctuations in world commodity prices that occurs for major commodity exporters. The magnitude of this response, however, varies widely among countries. Our panel data analysis using 63 countries for...
