| Abstract: | Fifteen per cent of British babies are now born to parents who are neither cohabiting nor married. Little is known about non-residential fatherhood that commences with the birth of a child. Here, we use the Millennium Cohort Study to examine a number of aspects of this form of fatherhood. Firstly, we consider the extent to which these fathers were involved with or acknowledged their child at the time of the birth. Secondly, we identify the characteristics that differentiate parents who continue to live apart from those who move in together. Thirdly, for the fathers who moved in with the mother and their child we enquire whether they differ in the extent of their engagement in family life compared with fathers who have been living with the mother since birth. Finally, for fathers who were living apart from their child when the child was 9 months old we assess the extent to which they were in contact, contributed to their maintenance and were involved in their child's life at this time. |

| Abstract: | Does the death penalty save lives? A surge of recent interest in this question has yielded a series of papers purporting to show robust and precise estimates of a substantial deterrent effect of capital punishment. We assess the various approaches that have been used in this literature, testing the robustness of these inferences. Specifically, we start by assessing the time series evidence, comparing the history of executions and homicides in the United States and Canada, and within the United States, between executing and non-executing states. We analyze the effects of the judicial experiments provided by the Furman and Gregg decisions and assess the relationship between execution and homicide rates in state panel data since 1934. We then revisit the existing instrumental variables approaches and assess two recent state-specific execution morartoria. In each case we find that previous inferences of large deterrent effects based upon specific examples, functional forms, control variables, comparison groups, or IV strategies are extremely fragile and even small changes in the specifications yield dramatically different results. The fundamental difficulty is that the death penalty -- at least as it has been implemented in the United States -- is applied so rarely that the number of homicides that it can plausibly have caused or deterred cannot be reliably disentangled from the large year-to-year changes in the homicide rate caused by other factors. As such, short samples and particular specifications may yield large but spurious correlations. We conclude that existing estimates appear to reflect a small and unrepresentative sample of the estimates that arise from alternative approaches. Sampling from the broader universe of plausible approaches suggests not just "reasonable doubt" about whether there is any deterrent effect of the death penalty, but profound uncertainty -- even about its sign. |

| Abstract: | Donohue and Levitt (2001) argue that the legalization of abortion in the United States in the 1970s played an important role in explaining the observed decline in crime approximately two decades later. Foote and Goetz (2005) challenge the results presented in one of the tables in that original paper. In this reply, we regretfully acknowledge the omission of state-year interactions in the published version of that table, but show that their inclusion does not alter the qualitative results (or their statistical significance), although it does reduce the magnitude of the estimates. When one uses a more carefully constructed measure of abortion (e.g. one that takes into account cross-state mobility, or doing a better job of matching dates of birth to abortion exposure), however, the evidence in support of the abortion-crime hypothesis is as strong or stronger than suggested in our original work. |

| Abstract: | This paper estimates effects of increases in incarceration length on employment and earnings prospects of individuals after their release from prison. I utilize a variety of research designs including controlling for observable factors and using instrumental variables for incarceration length based on randomly assigned judges with different sentencing propensities. The results show no consistent evidence of adverse labor market consequences of longer incarceration length using any of the analytical methods in either the state system in Florida or the federal system in California. |

| Abstract: | New information technology has reduced marginal production and distribution costs of information goods to negligible levels and promises to revolutionize many industries. Unpaid copies of digital products can be as good as paid first-generation copies, and their availability can undermine the ability of sellers to cover first-copy costs. As a result, unpaid distribution has emerged as a major issue facing the music and movie industries in the past few years. Using survey data on movie consumption by about 500 University of Pennsylvania college students, we ask whether unpaid consumption of movies displaces paid consumption. Employing a variety of cross-sectional and longitudinal empirical approaches, we find large and statistically significant evidence of displacement. In what we view as the most appropriate empirical specifications, we find that unpaid first consumption reduces paid consumption by about 1 unit. Unpaid second consumption has a smaller effect, about 0.20 units. These estimates indicate that unpaid consumption, which makes up 5.2 percent of movie viewing in our sample, reduced paid consumption in our sample by 3.5 percent. |

| Abstract: | Using data from three waves of Add Health we find that being very attractive reduces a young adult's (ages 18-26) propensity for criminal activity and being unattractive increases it for a number of crimes, ranging from burglary to selling drugs. A variety of tests demonstrate that this result is not because beauty is acting as a proxy for socio-economic status. Being very attractive is also positively associated adult vocabulary test scores, which suggests the possibility that beauty may have an impact on human capital formation. We demonstrate that, especially for females, holding constant current beauty, high school beauty (pre-labor market beauty) has a separate impact on crime, and that high school beauty is correlated with variables that gauge various aspects of high school experience, such as GPA, suspension or having being expelled from school, and problems with teachers. These results suggest two handicaps faced by unattractive individuals. First, a labor market penalty provides a direct incentive for unattractive individuals toward criminal activity. Second, the level of beauty in high school has an effect on criminal propensity 7-8 years later, which seems to be due to the impact of the level of beauty in high school on human capital formation, although this second avenue seems to be effective for females only. |
