In a pro-male biased society, brothers may reduce the parental investment received by female siblings, if parents face time or financial constraints. But brothers may also cause positive externalities. Using more than 12,000 firstborn twins from a highly sex-imbalanced economy, Taiwan, we test...

The veterans disability compensation (VDC) program, which provides a monthly stipend to disabled veterans, is the third largest American disability insurance program.

Since Akerlof's (1970) seminal paper the existence of adverse selection due to asymmetric information about quality is well-understood. Yet two questions remain. First, given the negative implications for trading and welfare, how do such markets come into existence? And second, why have many...

Although households are responsible for many important decisions, they have rarely been the subject of economics experiments.

This paper examines the role of the coalition formation process in a proportional system. It models its impact on the voters (who maximize their expected utilities) and the parties (who choose their platforms in a Nash game). In contrast with the intuitive idea that proportional systems...

By promoting some of the poor into the middle class and thereby co-opting them into the system, a self-interested elite reduces the threat of political instability and the risk of being overthrown. Co-optation is accomplished through the transfer of resources to some of the poor, enabling them...
