This paper investigates the effect of economic integration on the ability of firms to maintain a collusive understanding about staying out of each other's markets. The paper distinguishes among different types of trade costs: ad valorem, unit, fixed. It is shown that for a sufficient reduction of ad valorem trade costs, a cartel supported by collusion on either quantities or prices will be weakened, ...
This paper presents two new tools for the identification of faking interviewers in surveys. One method is based on Benford's Law, and the other exploits the empirical observation that fakers most often produce answers with less variability than could be expected from the whole survey. We focus on fabricated data, which were taken out of the survey before the data were disseminated in the German Socio-Economic ...
Incomplete data is a common problem of survey research. Recent work on multiple imputation techniques has increased analysts' awareness of the biasing effects of missing data and has also provided a convenient solution. Imputation methods replace non-response with estimates of the unobserved scores. In many instances, however, non-response to a stimulus does not result from measurement problems that ...
This paper investigates the link between the optimal level of nonfinancial firms' leverage and macroeconomic uncertainty. We develop a structural model of a firm's value maximization problem that predicts that as macroeconomic un-certainty increases the firm will decrease its optimal level of borrowing. We test this proposition using a panel of non{financial US firms drawn from the COM-PUSTAT quarterly ...
Many validation studies deal with item nonresponse and measurement error in earnings data. In this article, the author explores respondents' motives for failing to revealearnings using the German Socio-Economic Panel (SOEP). The SOEP collects socioeconomic information from private households in the Federal Republic of Germany.The author explains the evolution of income nonresponse in the SOEP and demonstrates ...
This paper investigates empirically for the first time the impact of experts' agreement on voter turnout. Data were obtained when voters, advised by four independent experts, had to decide on the next move against a chess world champion. Analyzing total voter turnout as well as individual voters' behavior in a panel data subsample, and employing OLS median and ARMAX regression techniques, we find that ...
