 During extensive public debate on the Consumer Price Index in the 1990s, Abraham testified repeatedly before Congress on the shortcomings of existing methodology and the necessity of making revisions based on objective research.She expanded coverage of the prices of services in the Producer Price Index; instituted improvements in the Current Employment Statistics, including the substitution of a probability sample for the quota sample; accelerated delivery of employment and wage statistics; and took steps toward expanding coverage of wages and salaries in the Occupational Employment Statistics program.Abraham's research has included studies of the effects of job duration on wages; the effects of advertising on job vacancies, wages and the business cycle; and comparisons among the U.S., European, and Japanese labor markets; work-sharing policies, unemployment, and job openings; the operation of internal labor markets; and the measurement of market and nonmarket economic activity.
