Abstract:
Two-stage examinations consist of a first stage in which students work individually as they typically do in examinations (stage 1), followed by a second stage in which they work in groups to complete another examination (stage 2), which typically consists of a subset of the questions from the first examination. Data from two-stage midterm and final examinations are used to assess the extent to which individuals improve their performance when collaborating with other students. On average, the group (stage 2) score was about one standard deviation above the individual (stage 1) score. While this difference cannot be interpreted as the causal effect of two-stage examinations on learning, it suggests that individuals experienced substantial performance gains when working in groups in an examination. This average performance gain was comparable with the average difference between the top performer of the group in stage 1 and the group’s stage 1 average, and was equivalent to about two-thirds of the difference between the “super student” score (i.e. the sum of the maximum score for each question in stage 1) and the group’s stage 1 average. This last result suggests that group collaboration takes substantial (albeit partial) advantage of the aggregate knowledge and skills of the group’s individual members. Student feedback about their experience with two-stage examinations reveal that that these types of examinations are generally perceived to be more helpful for learning and are less stressful than traditional examinations. Finally, using data on group gender compositions, we investigate the potential role of gender dynamics on group efficiency.

2. From Clans to Co-Ops: Confiscated Mafia Land in Sicily

Abstract:
From Clans to Co-ops explores the social, political, and economic relations that enable the constitution of cooperatives operating on land confiscated from mafiosi in Sicily, a project that the state hails as arguably the greatest symbolic victory over the mafia in Italian history. Rakopoulos’s ethnographic focus is on access to resources, divisions of labor, ideologies of community and food, and the material changes that cooperatives bring to people’s lives in terms of kinship, work and land management. The book contributes to broader debates about cooperativism, how labor might be salvaged from market fundamentalism, and to emergent discourses about the ‘human’ economy.

3. Toward a More Efficient Taxation System in New Zealand

Abstract:
After the radical reforms undertaken in the 1980s, the NZ tax system has long been regarded as one of most efficient within the OECD, and is based on a comprehensive income approach. Looking forward, the country will require a tax regime that helps the economy to continue raising living standards, supports savings and investment and copes with emerging pressures such as increasing geographic mobility of labour and capital. In this context, it will be important to have in place a clear long-term direction for the tax system to guide reforms. There are at least two broad options that are worth considering: adapting the system within a comprehensive income approach or adopting a dual income tax system. Future changes to the tax system need to be consistent with the approach ultimately adopted. In any case, a number of limitations of current tax bases will need to be tackled.
