Fetal Malnutrition and Academic Achievement

Jane Greve, Marie Louise Schultz-Nielsen, and Erdal Tekin find that Muslim children in Denmark who were in utero during Ramadan, a time when Muslim mothers might have fasted, exhibit lower test scores on academic achievement tests than children of similar mothers who were born at other times. The results are stronger for girls than for boys, and are most pronounced for children with low socioeconomic status (SES) background.

Tax Evasion across Industries:
Soft Credit Evidence from Greece

Working with microdata on household credit from a Greek bank, Nikolaos Artavanis, Adair Morse, and Margarita Tsoutsoura estimate that more than 43 percent of income of self-employed individuals in Greece goes unreported and untaxed. For 2009, this lost tax revenue exceeded 11 billion euros, or 30 percent of the nation’s deficit. They find the primary tax-evading industries are medicine, law, engineering, education, and media.

The Financial Feasibility of Delaying Social Security:
Evidence from Administrative Tax Data

Most people claim Social Security before the full retirement age despite large and growing returns for deferring. Gopi Shah Goda, Shanthi Ramnath, John B. Shoven, and Sita Nataraj Slavov find evidence that early claimers have higher subjective and actual mortality rates than those who claim later, suggesting that private information about expected future lifetimes may influence claiming behavior.

How Powerful Are Fiscal Multipliers?

Recent analysis suggests that a $1 increase in government spending or decrease in taxes stimulates $1.50 to $2 in output during recessions, but only about $0.50 during expansions, Alan Auerbach and Yuriy Gorodnichenko write in the current issue of the NBER's quarterly Reporter. Also featured in this issue are reports on the rising interest in macroprudential policies, the democracy/development relationship, the economics of happiness, and the effects of early childhood interventions.

How China's Transition to a Developed Economy
Differed from the Experiences of the West

Dividing Chinese enterprises into "heavy" and "light" sectors rather than comparing the state-owned and privately-owned sectors provides fresh insight into the country's macroeconomy, according to research presented in the October issue of the NBER Digest. Other reports in this month's Digest examine the credibility of China's unemployment statistics, the recession-era shopping habits of Americans, the power of nudges, barriers to new technology, and the impact on hospitals of patients who don't pay up.

Enterprising America

Businesses, Banks, and Credit Markets in Historical Perspective

The rise of America from a colonial outpost to one of the world's most sophisticated and productive economies was facilitated by the establishment of a variety of economic enterprises pursued within a framework of laws and institutions that set the rules for their organization and operation. To better understand the historical processes central to American economic development, this NBER Conference Report brings together contributors who address the economic behavior of American firms and financial institutions and the legal institutions that shaped their behavior in the 19th and early 20th centuries. Among the topics are the rise of incorporation and its connection to manufacturing in factories, the organization and operation of large cotton plantations in comparison with factories, the regulation and governance of banks, the transportation revolution's influence on bank stability and survival, and the emergence of long-distance credit in the context of an economy that was growing rapidly and becoming increasingly integrated across space.
