Reforming rape laws

Almost all legislative evaluations and impact analyses in the area of rape reform have involved the U.S. This article examines the effects of rape reform legislation introduced in Canada in 1983. In that year the offenses of rape and indecent assault were replaced with three new offenses of sexual assault. As in other jurisdictions in the U.S., the Canadian reforms were designed to achieve several aims. These included increasing the number of victims reporting to the police, reducing the proportion of reports classified by the police as unfounded, and increasing the number of cases in which a charge is laid. This article presents a time-series analysis of reports of crimes of sexual aggression over a 10-year period around passage of the reform legislation. The results indicate that there was a significant increase in the number of reports of these crimes concurrent with the passage of the legislation. Moreover, the increase in sexual assault reports exceeds by a significant margin the increase in reports made of other personal injury offenses (e.g., assault). However, the legislation has had no discernible effect upon the immediate criminal justice response to reports of sexual aggression: Neither the percentage of reports classified as founded, nor the percentage of reported incidents resulting in the laying of a charge has changed.The authors would like to gratefully acknowledge the comments made upon an earlier draft of this article by Ed Renner, the editor of the journal, and an anonymous reviewer.

Industry as a mechanism for urban technology transfer

This paper is based upon research done under the National Science Foundation sponsored study The Role of Industry in Urban Technology Transfer: A Comparative Profile. The purpose of the research is to investigate specific industries that serve the urban market of local governments. The research aim is to develop an understanding for the barriers and incentives that affect industry's ability and desire to produce and market technological innovations for cities.     

Adjusting for Confounding with Text Matching

We identify situations in which conditioning on text can address confounding in observational studies. We argue that a matching approach is particularly well-suited to this task, but existing matching methods are ill-equipped to handle high-dimensional text data. Our proposed solution is to estimate a low-dimensional summary of the text and condition on this summary via matching. We propose a method of text matching, topical inverse regression matching, that allows the analyst to match both on the topical content of confounding documents and the probability that each of these documents is treated. We validate our approach and illustrate the importance of conditioning on text to address confounding with two applications: the effect of perceptions of author gender on citation counts in the international relations literature and the effects of censorship on Chinese social media users.
