This paper describes a new attrition screen for nonhigh school diploma graduate (NHSDG) applicants for service in the U.S. Army. A sample of 21,432 NHSDG Army accessions from FY00 through FY03 was used in the model development process. The new screen combines several indicators of adaptability from the motivational, mental, and physical fitness domains to forecast the likelihood of an NHSDG app...

Selective Migration and Health Using data from the Panel Study of Income Dynamics, we investigate the impact of health on domestic migration within the United States. We find that, for men below 60 years of age, a move from the middle to the bottom of the health distribution reduces mobility by 32-40%. Non-random attrition from the panel implies that these are lower bounds. By contrast, we find...

We study the exit behavior of a firm in multiple declining markets with an extension of Ghemawat and Nalebuff (1985) to a multimarket environment. We find that the multimarket firms pool their commitment of staying in individual markets when there are technological complementarities between markets, and thereby, may change the credibility of the threat of staying in the war of attrition. The la...

The aim of this paper is to provide the reader with a general overview of the field of attrition. Having situated this relatively new research domain with respect to related fields and approaches, a brief summary of the most important research questions and preliminary findings is given. The discussion then focuses on two issues that are of particular interest with respect to neurolinguistics: ...

As survey response rates decline, correlates of survey participation may also be changing. Panel studies provide an opportunity to study a rich set of correlates of panel attrition over time. We look at changes in attrition rates in the American National Election Studies from 1964 to 2004, a repeated panel survey with a two-wave pre-post election design implemented over multiple decades. We exa...

In this paper I present evidence that sample selection or attrition introduces very little bias into growth rate equations over time periods of approximately five to ten years. In this appendix I present the results of a time series analysis of three sets of firms (those in the sample from 1972 to 1979, from 1976 to 1983, and the combined sample from 1972 to 1983) with some confidence that thes...

We study the war of attrition and the all-pay auction when players’ signals are affiliated and symmetrically distributed. We (a) find sufficient conditions for the existence of symmetric monotonic equilibrium bidding strategies; and (b) examine the performance of these auction forms in terms of the expected revenue accruing to the seller. Under our conditions the war of attrition raises greater...
