Forecasting U.S. social security disability applications
Coping with health shocks in American households
Getting the ROC into Sync
Judging the conformity of binary events in macroeconomics and finance has often been done with indices that measure synchronization. In recent years, the use of Receiver Operating Characteristic (ROC) curve has become popular for this task. This article shows that the ROC and synchronization approaches are closely related, and each can be derived from a decision-making framework. Furthermore, the resulting global measures of the degree of conform…

Productive efficiency in processing social security disability claims
Confidence Bands for ROC Curves With Serially Dependent Data
We propose serial correlation-robust asymptotic confidence bands for the receiver operating characteristic (ROC) curve and its functional, viz., the area under ROC curve (AUC), estimated by quasi-maximum likelihood in the binormal model. Our simulation experiments confirm that this new method performs fairly well in finite samples, and confers an additional measure of robustness to nonnormality. The conventional procedure is found to be markedly …
Fetal growth and neurobehavioral outcomes in childhood
Identifying the Mechanisms for Workplace Burden of Psychiatric Illness
BACKGROUND: Although previous research indicates that mental disorders detract from labor market outcomes, little is known about which psychiatric symptoms are most important. OBJECTIVE: The objective of this study was to identify the mechanisms, or most important symptoms, through which psychiatric disorders affect labor market outcomes. We focus on major depressive episode, panic attack, social phobia, and generalized anxiety disorder. Our appr…
A Structural Model of Social Security's Disability Determination Process
We estimate a multistage sequential logit model reflecting the structure of the disability determination process of the Social Security Administration (SSA). The model is estimated using household survey information exact-matched to SSA records on disability adjudications from 1989 to 1993. Under program provisions, different criteria dictate outcomes at different steps of the determination process. We find that, without the multistaged structura…
Estimation of a macroeconomic model with rational expectations and capital controls for developing countries
A Comparative Study of Alternative Methods of Quantifying Qualitative Survey Responses Using Napm Data
This article examines the effectiveness of a subjective probability approach to quantify three- category qualitative responses from expectations surveys. Since one cannot make a judgment on the validity of estimated expectations by comparing them with ex post outcomes, we use the National Association of Purchasing Managers survey data on materials buying prices and compare them with the Producer Price Index for intermediate materials and componen…
The Estimation and Interpretation of Urban Density Gradients
The negative-exponential varying-parameter, density-gradient model is generalized by introducing the Box–Cox transformation in conjunction with truncated and heteroscedastic errors. An interpretation of this density-gradient model is presented, based directly on the magnitude and response of the expected value of population density to changes in the model's conditioning variables. Previous studies interpreted the gradient parameters purely as des…
More Flexible Use of Survey Data on Expectations in Macroeconomic Models
A flexible procedure is proposed whereby both the random and systematic errors in measurement of survey data on inflation expectations can be appropriately handled when these surveys are used in the estimation of macroeconomic models. During the period 1952–1980, Livingston's two expectations series and the SRC series systematically underestimated inflation expectations by nearly 25%. The ASA–NBER survey, however, does not exhibit such underestim…
