An analysis of strategic behavior in eBAY auctions
(World Scientific Publishing Co. Pte. Ltd., 2009) Gonzalez, R.; Hasker, K.; Sickles, R. C.
A relatively new type of panel data analysis is becoming more and more topical in the applied econometrics literature as auction mechanisms are being explored in more depth. The typical data utilized in such studies involves repeated measures of auction outcomes, where the variable of interest involves order statistics from the sample of bids from many bids on completed auctions for a particular commodity. This article presents structural estimates of bidding behavior in eBay computer monitor auctions. We exploit characteristics of such repeated measures to analyze the efficiency of private value auctions for a relatively homogeneous good, computer monitors sold on eBay. We discuss how outcomes of the auction mechanism can be analyzed and their equilibrium outcomes assessed and evaluate the consumer surplus that is generated from such auctions. Particular attention is given to the collection of the eBay data from data recovery protocols that monitor in real time and in relative detail, characteristics of a particular auction with heterogeneity controls for different types of monitors and for different reputation effects of the auctioneer. Among other findings, our results point to a rejection of the use of Jump Bidding (Avery, 1998) or "Snipe or War" bidding (Roth and Ockenfels, 2002). We also find that longer auctions only have a small effect on price and experienced auctioneers respond to this incentive. © 2009 World Scientific Publishing Company.

In the presence of climate change, the use of fertilizers and the effect of income on agricultural emissions
(M D P I AG, 2017) Erbas, B. C.; Solakoglu, E. G.
This study looks into the factual link between nitrogen fertilizer use and the land annual mean temperature anomalies arising from climate change, incorporating the effect of income and agriculture share to understand better their impact on emissions from agricultural activities along climate indicators. The study unearths causalities associated with this link by employing the Vector Error Correction Model (VECM) with back-dated actual panel data specifically constructed for this study by combining four datasets from 2002 to 2010. In the long-run, the causality is significant and unidirectional, indicating that income, agriculture share, and land temperature anomalies cause agricultural emissions, and that disequilibrium from such emissions is not eliminated within a year. In the short-run, the effective use of nitrogen fertilizers and other associated agricultural practices can be achieved as countries approach per capita income of 7000 USD. Changes in the structure of economies have an expected effect on agricultural emissions. Temperature anomalies increase agricultural emissions from nitrogen fertilizers, possibly due to the fact that the potential negative impacts of these anomalies are mitigated by farmers through changes in crop production inputs. Therefore, as part of adoption strategies, to avoid the excessive and inefficient use of nitrogen fertilizers by farmers, economic incentives should be aligned with the national and global incentives of sustainability. © 2017 by the authors.

The resource curse and child mortality, 1961–2011
(Elsevier Ltd, 2017) Wigley, S.
There is now an extensive literature on the adverse effect of petroleum wealth on the political, economic and social well-being of a country. In this study we examine whether the so-called resource curse extends to the health of children, as measured by under-five mortality. We argue that the type of revenue available to governments in petroleum-rich countries reduces their incentive to improve child health. Whereas the type of revenue available to governments in petroleum-poor countries encourages policies designed to improve child health. In order to test that line of argument we employ a panel of 167 countries (all countries with populations above 250,000) for the years 1961–2011. We find robust evidence that petroleum-poor countries outperform petroleum-rich countries when it comes to reducing under-five mortality. This suggests that governments in oil abundant countries often fail to effectively use the resource windfall at their disposal to improve child health.
