The living commons of West Tyrol,Austria: Lessons for land policy and land administration

A right of commoners to pastures existed since the Early Middle Ages in Anglo-Saxon England and the European mainland, including Tyrol in Austria. Lowland commons institutions were largely dissolved by the 19th century; however, in the European Alps contiguous commons remain alive. Some two thousand alpine commons institutions are registered in the Tyrolean parcel cadaster and land registry. A specific study of West-Tyrolean commons (known as Agrargemeinschaft or AGMs), framed by Ostrom's design principles is presented. General lessons for land policy and land administration are extracted. An interview period was split between the Inn valley and the Ötztal. Roughly half are considered independent: others are regulated by the Tyrolean Agricultural Authority. Some AGMs hold the full bundle of land rights: others only hold pastoral and forestry rights. AGMs consisted either of a single cadastral parcel or several contiguous parcels. In the Inn valley villages the pastoral commons were owned by the municipalities, while in the researched Ötztal, AGMs are frequently the full owners of the commons. AGM membership ranges between 5 and 60 farm households. The number of livestock units pastured was in most cases stipulated in approved regulations. Alpine commons larger than 200 ha are also hunting-zones: revenue is collected from the lease of hunting rights. Most of the alpine commons are designated and used as ski-zones. Upper portions of two alpine commons in the Ötztal are state protected natural areas. The number of farms with pastoral rights is declining at District and State level. Key lessons for land policy and land administration include: Ostrom's design principles being a precondition rather than a panacea; commons institutions requiring one clear ownership party; both public and collective ownership producing success; publically owned commons requiring a local representative; small membership numbers being preferable; small shareholdings not being preferable; decentralized governance being beneficial; internal democratic elections being beneficial; internal boundary records being superfluous; explicit sanctions being superfluous; mixed economies being acceptable; and geography being a significant influence on the longevity of pastoral commons.     

TIME‐CONSISTENT AND MARKET‐CONSISTENT EVALUATIONS

We consider evaluation methods for payoffs with an inherent financial risk as encountered for instance for portfolios held by pension funds and insurance companies. Pricing such payoffs in a way consistent to market prices typically involves combining actuarial techniques with methods from mathematical finance. We propose to extend standard actuarial principles by a new market‐consistent evaluation procedure which we call “two‐step market evaluation.” This procedure preserves the structure of standard evaluation techniques and has many other appealing properties. We give a complete axiomatic characterization for two‐step market evaluations. We show further that in a dynamic setting with continuous stock prices every evaluation which is time‐consistent and market‐consistent is a two‐step market evaluation. We also give characterization results and examples in terms of g‐expectations in a Brownian‐Poisson setting.

How successfully China has applied the OECD principles of corporate governance: a critical assessment

This paper attempts to critically analyze how successful China has been in applying the OECD principles of corporate governance. In doing so, assessment has been made in light of the six core issues of the OECD principles. A satisfactory level of progress has been noted in China’s legal and regulatory framework since the 1990s. New laws, regulations, and rules have been enacted, existing ones have been amended, and all the required institutions have been built accordingly in order to ensure good corporate governance practices in the country. However, there are still bottlenecks in terms of the enforcement of these laws, regulations, and rules mainly due to the various structural limitations in the Chinese administration and judiciary. The paper argues that China should now move forward with an accelerated enforcement agenda in the area of corporate governance in order to make China Inc. more competitive and sustainable.     

On Teacher Politeness Principles in EFL Classroom

It is proved that teachers' politeness behavior can highly motivate students' learning impulse and improve teaching process. Politeness phenomenon in classroom has been broadly discussed and studied; however, there are still no systematic politeness principles that can be reasonably applied into the teaching process. On the basis of the politeness theories and a case study, this paper tries to seek a more reasonable and more efficient politeness principle in EFL classroom.     

The emergence of home-based accommodations in Iran: A study of self-organization

This paper examines the Iranian home-based accommodation sector using the theory of self-organization. With the aim of identifying the sector's organizing principles, interviews were conducted with the accommodation operators, providing 117 statements which were linked based on their key ideas and/or words. Using UCINET6, a network diagram of five organizing principles were identified: collective identity, balanced legitimacy, local embeddedness, mindful market, and networked finance. While the combination of these organizing principles is interpreted within the Iranian context, broad assumptions can be inferred. It is speculated that a collective aiming to organize itself needs to be considerate of its interactions with members of the collective, the authoritative body, the local community, the market, and capital. Additionally, each separate organizing principle might have relevance for small businesses in various industries. The study contributes to the commercial home and home-based accommodation literature while also providing insights into tourism development in Iran. Furthermore, the method used to identify organizing principles is considered novel and can be used with other collectives.     

HOW COOPERATIVE ARE SAVINGS AND CREDIT COOPERATIVES IN DEVELOPING COUNTRIES?: AN ANALYSIS OF DATASETS FROM UGANDA

Building successful savings and credit cooperatives (SACCOs) that actually embody the cooperative principles is a challenge to development agencies. Although SACCOs form the majority of microfinance providers in many developing countries, the most recent literature on microfinance governance and performance has given little reference to the longstanding body of relevant cooperative literature. SACCO representation in microfinance datasets is biased. Drawing on so‐far unexploited datasets of Ugandan SACCOs and savings groups, this paper empirically analyses policy debate regarding SACCO‐ and savings group regulation. The findings point to the relevance of practically implementing the principle of ‘cooperation between cooperatives’ to ensure effective governance at SACCO level. Moreover, the paper introduces two new measures, based on members' savings and shares, which could become useful tools to track the application of cooperative principles in developing countries, and hence improve evidence‐based policy‐making for SACCOs.     

Simulating Price-Taking

In this article, the author presents a price-takers’ market simulation geared toward principles-level students. This simulation demonstrates that price-taking behavior is a natural result of the conditions that create perfect competition. In trials, there is a significant degree of price convergence in just three or four rounds. Students find this simulation to be a fun, educational experience that adds value to their understanding of competitive markets.
