The deterrence hypothesis revisited

This study explores the causes of crime and the differences in deterrent effects of policing on crimes among rural, suburban, and urban communities. We hypothesize that certain numbers of all crimes are unaffected by policing due to their high net return; policing deters only marginal crimes. That is, unlike other research efforts, we recognize that there is a level of crime indigenous to a given type of community about which little can be done, although a particular community can affect deviations from this level. By introducing this ‘natural rate' of crime we are able to empirically reveal the deterrence effect of police expenditures upon all types of property crimes except robberies. The study analyzes 230 communities in a system of six simultaneous equations, using police, crime, and other socio-economic variables. The model can be used by state and regional policy-makers to more effectively allocate resources to the different types of communities under their jurisdiction and among the various police functions designed to deter specific types of crime.     

Structural sign patterns and reduced form restrictions

This paper reconsiders the degree to which the sign patterns of hypothesized structural arrays limit the possible outcomes for the sign pattern of the corresponding estimated reduced form. The conditions under which any structural restrictions would apply were believed to be very narrow, rarely found to apply, and virtually never investigated. As a result, current practice does not test the structural hypothesis in terms of the comparison of the estimated reduced form and the permissible reduced form sign patterns. This paper shows that such tests are always possible. Namely, that the sign patterns of the hypothesized structural arrays always limit the sign patterns that can be taken on by the estimated reduced form. Given this, it is always possible to falsify a structural hypothesis based only upon the sign pattern proposed. Necessary conditions, algorithmic principles, and examples are provided to illustrate the analytic principle and the means of its application.     

Internal trade,productivity and interconnected industries: A quantitative analysis

Does trade within a country affect welfare and productivity? What are the magnitude and consequences of costs to such trade? To answer these questions, we exploit unique Canadian data to measure internal trade costs in a variety of ways—they are large and vary across sectors and provinces. To quantify their consequences for welfare and productivity, we use a recent multi‐sector trade model featuring rich input–output relationships. We find interprovincial trade is an important contributor to Canada's GDP and welfare, though there are significant costs to such trade. Reducing interprovincial trade costs by 10% yields aggregate gains of 0.9%; eliminating our preferred estimates of costs, gains average between 3% and 7%—equivalent to real GDP gains between $50 billion and $130 billion. Finally, as policy reforms are often sector specific, we liberalize sectors one at a time and find gains are largest in highly interconnected industries.

Entrepreneurial versus cooperative social capital: The impact on operational performance

Research has extensively focused on how firms can become more competitive, by discovering new knowledge domains while exploiting current ones. Prior research has shown the positive impact of social capital on performance; however, there have been no empirical studies that distinguished between the architectures of social capital and how they impact the operational performance dimensions. Building upon the knowledge-based theory, we propose a model to examine the effects of the two architectures of social capital (entrepreneurial and cooperative) on individual dimensions of operational performance (quality, delivery, flexibility and cost). The hypotheses are tested using structural equation modelling and data collected from 182 companies in Ireland. The results show that the cooperative social capital archetype supports the operational performance dimensions, while the entrepreneurial social capital archetype only impacts the cost dimension. The findings extend the current understanding about the complex relationships among the architectures of social capital and provide guidance for managers on how to leverage their investments in social capital to enhance specific operational performance dimensions.     

Job satisfaction in teams

This paper analyses and discusses the results of a large sample survey of job satisfaction among clerical employees working in teams. The relative strengths of association between several variables and job satisfaction are assessed and the results support the importance of on-the-job training, participation in decision making and management leadership. Questions are raised about first-line supervisors as team leaders.     

Does host-country education mitigate immigrant inefficiency? Evidence from earnings of Australian university graduates

Imperfect transferability of skills remains a dominant argument in explaining lower earnings of immigrants. Acquisition of host-country education plays a c
