Property Crimes and the Police: An Empirical Analysis of Swedish Data
利用瑞典278个市镇1975-1976年的数据，通过联立方程模型分析警察工作对财产犯罪的影响，发现警察工作能有效威慑犯罪。
The results of a study of the impact of police work on property crimes are reported. The data base is a cross-section of 278 Swedish municipalities during the years 1975 and 1976. A three-equation simultaneous model is compared with a simpler two-equation model. The results indicate that the simpler system is preferable. In the estimates of both models, most parameters are significant with the expected signs. Police work seems to deter crime, as expected.
