美国金融危机对东亚新兴经济体的贸易传染渠道分析

美国金融危机到底以何种方式在全球传播，以至于演变成全球经济海啸，一直是近几年学术界所关注的问题之一。本文以美国金融危机对外传播的贸易传染渠道为切人点，分析了美国金融危机通过贸易伙伴型传染和贸易竞争对手型传染这两个贸易传染子渠道对东亚新兴经济体的溢出程度。对面板数据进行的GLS实证结果显示，美国金融危机通过贸易传染渠道的溢出，与大部分东亚新兴经济体经济波动之间存在10％以上显著性水平的相关性，因而贸易传染渠道是美国金融危机对东亚溢出的一个重要机制。     

Does border enforcement deter unauthorized immigration? The case of Mexican migration to the United States of America

This paper asks whether the migration decisions of unauthorized Mexican immigrants to the USA have been influenced by stronger US border enforcement efforts since 1993 that have sharply increased the physical risk and financial cost of illegal immigration. These measures were supposed to have decreased the probability of successful entry, thereby lowering the expected benefits of migration. We carried out a logistic regression analysis of data from a recent survey of 603 returned migrants and potential first‐time migrants in rural Mexico. Our findings indicate that tougher border controls have had remarkably little influence on the propensity to migrate illegally to the USA. Political restrictions on immigration are far outweighed by economic and family‐related incentives to migrate. An alternative, labor‐market approach to immigration control with higher probability of effectiveness is outlined.

Measurement Properties of the Communities That Care<Superscript>®</Superscript> Youth Survey Across Demographic Groups

Prevention science has produced information about risk and protective factors that predict adolescent drug use and related problem behaviors. This paper investigates the Communities That Care Youth Survey that measures multiple risk and protective factors. Using a sample of 172,628 students who participated in surveys administered in seven states in 1998, analyses were conducted to test the factor structure of these risk and protective factors and to test the equivalence of the factor models across five racial/ethnic groups (African Americans, Asians or Pacific Islanders, Caucasians, Hispanic Americans, and Native Americans), four grade levels (6th, 8th, 10th, and 12th) and both gender groups. Results support the construct validity of the surveys risk and protective factor scales and indicate that the measures are equally reliable across males and females and five racial/ethnic groups. Implications of these findings for science-based prevention planning are discussed.     

The case of the missing victims: Gunshot woundings in the National Crime Survey

National Crime Survey (NCS) data yield an estimate that 171,000 Americans were nonfatally shot in criminal assaults, robberies, and rapes for the period 1973–1979. Comparing this estimate with the number of firearms homicides during this period suggests either that the death rate in gunshot cases is very high (over 1/3) or that the NCS estimate is low. Based on police-generated data appropriate to estimating the true death rate from gunshot wounds, it appears that the NCS estimate is low by a factor of about 3.0 compared with the number of criminal gunshot woundings known to the police. It is common knowledge that survey-based estimates of assault rates tend to be relatively unreliable, a fact that has been attributed to problems with respondents being willing and able to recall threats, fist fights, and other minor assaults. The current result indicates that the estimation problem is not limited to minor assaults. There is reason to think that the underestimate of gunshot woundings is the result of problems with the NCS sample as well as problems with respondent cooperation.     

Methods for Understanding and Analyzing NIBRS Data

The National Incident-Based Reporting System (NIBRS) is an incident-basedcrime reporting program for local, state, and federal law enforcementagencies. Within each criminal incident, NIBRS captures information onoffenses, victims, offenders, property, and persons arrested, as well asinformation about the incident itself. The ability to link and analyze thisdetailed information is a significant improvement to the existing UniformCrime Reporting (UCR) summary reporting system. As one might expect,however, this increase in crime data significantly complicates the life ofthe data analyst, particularly when cross tabulating the NIBRS data. To dealwith the complexity of NIBRS data, one must understand its structure. Thisarticle provides an overview of the NIBRS structure and methods formaneuvering within it to present and interpret correctly cross tabulationsof the NIBRS data.     

Examining Space–Time Interaction in City-Level Homicide Data: Crack Markets and the Diffusion of Guns Among Youth

This paper examines the linkage between crack market activity and gunhomicide suggested by Blumstein (1995), who argues that the arrival ofcrack stimulated an increased availability of guns among juveniles. Thisgreater availability of guns, the argument continues, is responsible for thesharp upswing in juvenile homicide experienced in the United States in themid-1980s. Using city-level data on crack arrests and gun-related juvenilehomicide, we fit a change-point version of the Bass (1969) model ofinnovation diffusion. We find that, in most large American cities, thediffusion process for crack cocaine experienced an onset of dramatic growththat was followed by a similar, slightly slower growth in gun homicidescommitted by juveniles. We further use cluster analysis to find that thespatial patterning of the two processes is similar, starting on the East andWest Coasts and working their way toward other regions of the nation. Gunuse in homicide among slightly older offenders (ages 18–24) alsoexperienced a change at roughly the same time as the juveniles, but the rateof diffusion was considerably milder than for the younger group; offendersages 25 or older generally show no growth in gun-related homicide whatsoever. In addition, there is no detectable surge in juvenile nongun homicide activity. Based on these findings, we conclude that the crack cocaine markets–gun availability linkage is highly plausible, and we suggest directions for future research in clarifying the dynamics of the late-1980s surge in juvenile homicide.     

Opinion formation in foreign policy: the Swiss experience

Applying John Zaller's model of opinion formation to survey data covering 15 years (1981–95) of direct democracy in Switzerland, this paper provides a contribution to the debate about opinion formation in foreign policy. On the one hand, the Swiss experience contradicts the widespread view that citizens are poorly informed about and little interested in foreign affairs. On the other hand, direct democracy often translates into governmental defeats in this field. We address these mixed results and show that opinion formation in foreign policy is not a special case, and differs from that in domestic policy only with respect to the circumstances under which it occurs. In particular, we highlight the unusual type and level of conflict within the elite on foreign policy issues, which translates into distinct patterns of attitudes among the public.
