title: Sexonomics:  a commentary and review of selected sexually transmitted disease studies in the economics literature.
abstract: BACKGROUND
  The purpose of this review is to highlight selected studies in the economics literature that address sexually transmitted disease (STD)-related topics that are typically not examined in the STD literature.
  
  
  METHODS
  Two databases (EconLit and Web of Science) were searched to locate STD-related articles in the economics journals. Relevant articles were also identified in other ways, such as informal discussions with colleagues familiar with the literature. To maintain a focus on unique STD-related topics, studies with topics common in the STD literature (e.g., cost-effectiveness, transmission modeling) were excluded.
  
  
  RESULTS
  Selected STD-related studies in the economics literature were grouped into the following 8 topics: impact of abortion laws and policies on sexual health outcomes; same-sex marriage and syphilis rates; alcohol policy and STD rates; welfare laws and STD rates; discounting the future; HIV disclosure laws; the impact of tolerance for gays on HIV incidence; and economic versus epidemiologic models of HIV dynamics.
  
  
  CONCLUSIONS
  A general theme of STD-related studies in the economics literature is that laws and policies that increased the "cost" of risky sex tended to reduce the demand for risky sex, and therefore reduce the incidence of STDs. Economic research can contribute in novel ways to our understanding of influences on risky sexual behavior at the individual level and STD incidence at the population level. Economists and STD experts could mutually benefit from increased collaboration.
