We introduce a notion of fairness in the models for sponsored search auctions that provides a chance to new advertisers, as well as, lower budget advertisers to obtain better slots. This enables the search engines (i.e., auctioneers) to estimate the quality or relevance scores for new advertisers, and to better cater to the advertisers in the tail, and thereby encourage more advertisers to part...

In Australia, as electricity prices have increased, driven mainly by increases in peak demand, electricity use has decreased every year since 2008/09. The factors most responsible for these decreases include increased electricity costs, energy efficiency, solar water heaters and photovoltaics. Further increases in electricity prices and uptake of these technologies could result in further reduc...

We also evaluated our hypotheses using two additional firm performance measures: Tobin’s Q, which is the total dollar amount market value divided by the total dollar amount replacement value of a firm in a given year) and operating revenue/total assets, which is the total dollar amount of revenue divided by total dollar amount of assets of a firm in a given year. We selected these measures beca...

The paper is a survey of recent investigations by the authors and others into the relative efficiencies of structural and functional estimators of the regression parameters in a measurement error model. While structural methods, in particular the quasi-score (QS) method, take advantage of the knowledge of the regressor distribution (if available), functional methods, in particular the corrected...

This paper provides evidence of the role that financial market development and institutional quality play in integration European Union (EU) life insurance markets. It analyzes ten EU markets over a seventeen-year sample period. The meta-technology cost/revenue efficiency ratios, estimated under meta-frontier DEA framework, are used as measure analysis is conducted by applying Tobit panel regre...

This study estimates three hypotheses of OPEC behavior: market-sharing, target revenue and competitive model for the period 1980 to 2000 for all OPEC courtiers except Iraq. To examine co-integration relation for oil production, we use ADF test in OLS estimation. Also we use ARDL approach to examine these hypotheses and the long run relationship of them. Results indicate none of three hypotheses...

The fabless integrated circuit (IC) design is one of the most important sectors of the semiconductor industry. In 2010, the total revenue of the fabless IC design sector had already hit US$59.6 billion, accounting for one-fifth of the total semiconductor industry revenue. Thus, understanding the efficiency of fabless IC design houses is critical not only for managers of fabless IC design houses...

Iterative combinatorial auctions (ICAs) are IT-based economic mechanisms where bidders submit bundle bids in a sequence and an auctioneer computes allocations and ask prices in each auction round. The literature in this field provides equilibrium analysis for ICAs with non-linear personalized prices under strong assumptions on bidders’ strategies. Linear pricing has performed very well in the l...
