CHAPTER 4. YEAR-END SPENDING 181<br />
Congress, Deputy Assistant Attorney General Lee Lofthus may have been suggest<strong>in</strong>g<br />
a connection between those components of DOJ that contribute expir<strong>in</strong>g funds to the<br />
work<strong>in</strong>g capital fund <strong>and</strong> those that benefit from it when he noted that the FBI was<br />
both the biggest contributor to the fund <strong>and</strong> the biggest beneficiary (?).<br />
Given that rollover funds at DOJ are used for I.T. purposes, one might expect<br />
to see little or no end-of-year spike <strong>in</strong> I.T. spend<strong>in</strong>g, because I.T. components of<br />
the agency will know that they will directly benefit from funds contributed to the<br />
work<strong>in</strong>g capital fund. This is <strong>in</strong>deed the case. In the comprehensive FPDS data,<br />
only 3.4 percent of DOJ’s I.T. spend<strong>in</strong>g occurs <strong>in</strong> the last week—the 19th lowest of<br />
the 21 major agencies. In the I.T. dashboard data, DOJ has 16 ongo<strong>in</strong>g major I.T.<br />
<strong>in</strong>vestments, with planned total spend<strong>in</strong>g of just over $5.1 billion. Only 1 <strong>in</strong>vestment<br />
occurred <strong>in</strong> the last week of year. The $99 million cost of this <strong>in</strong>vestment implies<br />
that 1.9 percent of DOJ spend<strong>in</strong>g occurred <strong>in</strong> the last week compared to an average<br />
of 11.0 percent across the other agencies.<br />
Although the sample size of <strong>in</strong>vestments is very small, the quality of DOJ’s year-<br />
end spend<strong>in</strong>g is high. The one last week <strong>in</strong>vestment has the highest quality score of all<br />
major I.T. <strong>in</strong>vestments at the agency. Difference-<strong>in</strong>-differences estimates presented <strong>in</strong><br />
Table 4.8, which allow us to control for <strong>in</strong>vestment characteristics, suggest that the<br />
DOJ pattern is sufficiently unusual to be statistically significant—even though it is<br />
identified off of a s<strong>in</strong>gle end-of-year observation. Specifically, difference-<strong>in</strong>-differences<br />
po<strong>in</strong>t estimates <strong>in</strong>dicate that year-end quality <strong>in</strong>creases by 2.0 to 3.5 categorical levels<br />
at DOJ relative to other agencies. The p-values on the <strong>in</strong>teraction variable are less<br />
than 0.01 <strong>in</strong> all specifications.<br />
Despite the statistical <strong>and</strong> economic significance of the estimates, we are hesitant<br />
to draw strong conclusions from the estimated effect. In addition to the small number<br />
of projects, the fact that the effect is identified off of a s<strong>in</strong>gle agency raises the potential<br />
for bias from unobserved <strong>organization</strong>al characteristics. Nevertheless, the evidence<br />
that exists appears consistent with the prediction that rollover <strong>in</strong>creases year-end<br />
quality.
