This paper examines how the growth in vote-by-mail and changes in voting technologies led to changes in the residual vote rate in California from 1990 to 2010. We find that in California's presidential elections, counties that abandoned punch cards in favor of optical scanning enjoyed a significant improvement in the residual vote rate. However, these findings do not always translate to other races. For instance, find that the InkaVote system in Los Angeles has been a mixed success, performing very well in presidential and gubernatorial races, fairly well for ballot propositions, and poorly in Senate races. We also conduct the first analysis of the effects of the rise of vote-by-mail on residual votes. Regardless of the race, increased use of the mails to cast ballots is robustly associated with a rise in the residual vote rate. The effect is so strong that the rise of voting by mail in California has mostly wiped out all the reductions in residual votes that were due to improved voting technologies since the early 1990s.

Hong Kong plays a prominent role as a re-exporter of a large percentage of trade bound for or coming from China. Current reporting practices in China and its trading partners do not fully reflect this role and therefore provide a misleading picture of the origin or ultimate destination of Chinese exports and imports. We adjust bilateral trade data for both China and its trading partners to correct for this problem. We also correct for differences due to markups in Hong Kong and different standards for reporting trade (c.i.f. versus f.o.b.). For 2003, we estimate that China's overall trade surplus was between $53 billion and $126 billion, larger than that reported in official Chinese data, but smaller than that reported by China's trading partners. We also provide evidence that, in general, the actual origin of a good that is transshipped through Hong Kong is correctly reported by the importing country, but the final destination of such goods is not correctly reported by the exporting country.

To help people make informed decisions, policy-makers often require entities to provide consumers with informational materials known as disclosures. However, it is unclear whether consumers pay attention to disclosures. In two experiments where we manipulate the delivery of disclosures, we find that the mere presence of an observer negatively affects attention to disclosures, while introducing a mandatory waiting period after receiving a disclosure increases attention. In a third study, we analyze more than 3000 surveys answered by recent mortgage borrowers. Borrowers who report receiving disclosures at mortgage closing meetings (which are often attended by multiple stakeholders) are less likely to have questions about their disclosures than those who receive disclosures beforehand, suggesting differential attention. Our findings demonstrate that both mandatory waiting periods and the presence of observers can affect consumers’ attention to disclosures. We discuss implications of our research for policies designed to promote informed consumer decision-making.

Longitudinal survey and experimental research is essential for understanding psychological and economic processes, but attrition is a concern. We examine attrition in a 2016 longitudinal randomized controlled trial of more than 13,000 prospective U.S. homeowners, in which participants were invited to up to seven online surveys delivered every two weeks. Our research has two aims. First, we document overall attrition, finding that 60% of participants completed the study and attrition primarily occurred soon after enrollment. Second, we examine correlates of attrition, examining not only relationships with demographic and study characteristics (enrolling for text message reminders, survey delivery day) but also considering under-studied economic and psychological characteristics (time preferences, subjective numeracy, and financial literacy). Overall, we find that many variables, including some psychological characteristics, predict attrition. Our results suggest specific variables for researchers to measure in adjusting for attrition and identifying interventions to reduce attrition.
