An Experimental Study of Influences of Performance-Related Payments on Timing of Delegated Stock Purchases

Performance-related bonuses are important tools for investment organizations to incentivize stock traders. Yet, two experiments indicate that bonuses rewarding short-term performance may lead to worse timing of purchases. The authors propose that hyperbolic time discounting makes participants set lower aspired purchase prices for short-term (decreasing percentage) bonuses than for long-term (increasing percentage) bonuses. For this reason purchases are made earlier for decreasing than increasing percentage bonuses, earlier for decreasing than random prices, and earlier for high price volatility than for low price volatility. Neither purchases at the lowest price or highest bonus are attained. Hyperbolic time discounting may account for bubbles observed in experimental double-auction markets.     

Weakly fair allocations and strategy-proofness

This paper investigates the problem of allocating two types of indivisible objects among a group of agents when a priority-order must be respected and only restricted monetary transfers are allowed. Since the existence of a fair (as in envy-free) allocation is not generally guaranteed, due to the restrictions on the money transfers, the concept of fairness is weakened, and a new concept of fairness is introduced. This concept is called weak fairness. This paper defines an allocation rule that implements weakly fair allocations and demonstrates that it is coalitionally strategy-proof. In fact, under a mild regulatory condition and quasi-linear utility functions, it is demonstrated that this is the only coalitionally strategy-proof allocation rule that implements a weakly fair allocation.

Gender and conservation agriculture in East and Southern Africa: towards a research agenda

It is remarkable that despite wide-ranging, in-depth studies over many years, almost no conservation agriculture (CA) studies consider gender and gender relations as a potential explanatory factor for (low) adoption rates. This is important because CA demands new ways of working with the farm system. Implementation will inevitably involve a reallocation of men's and women's resources as well as having an impact upon their ability to realize their gender interests. With respect to intra-household decision-making and the distribution of benefits, CA interventions have implications for labour requirements and labour allocation, investment decisions with respect to mechanization and herbicide use, crop choice, and residue management. CA practice may impact upon the ability of households to source a wide variety of crops, wild plants, and insects and small animals for household nutrition. Gender biases in extension service design can sideline women. This paper examines the limited research to date on the interactions between CA interventions and gender in East and Southern Africa, and, based on the gaps observed, sets out a research agenda. It argues that attention to gender in CA is particularly timely given the increasing interest in CA as a means of adapting to climate change.     

The impact of advanced vocational education and training on earnings in Sweden

Researchers have established a relationship between greater education and training and higher earnings but it is difficult to infer that the former causes the latter if those with higher earnings tend to engage in more education and training. The present study attempts to control for ability and family background to see if stronger inferences can be made about education and training as the independent variable. The study focuses upon advanced vocational education and training (AVET) in Sweden. This is post‐secondary school education for individuals who are 20 years of age or older. The aim of this article is to estimate the effects of AVET on earnings by controlling for selection bias. We used various approaches such as instrumental variables, Hausman–Taylor estimates, fixed effects estimates and propensity score matching to achieve this aim. A panel, or longitudinal, data set for eight different labor markets in Sweden for the period 1996–2008 was used. The results indicate that earnings from AVET are higher than the return on investment in comprehensive education. The average effect on income is estimated to be in the range of 3–8 percent.     

Relationship development in Greenfield expansions

This paper investigates conceptually how new Greenfield subsidiaries develop relationships over time. We focus our analysis on the earliest start-up stage of new Greenfield subsidiaries, and on the dynamics of relationships development with five different groups of actors within the MNC and the local environment of the new Greenfield. We argue that relationship strength, or the intensity of interaction and resource exchange, depends on the new Greenfield's degree of dependence or interdependence within these relationships and develop propositions based on institutional theory, resource dependency theory and network approaches. In the concluding sections we suggest directions for future work to enhance understanding of the dynamics of relationship management in new Greenfield expansions.     

Tourism development: Assessing Social Gains and Losses

Resident attitudes toward tourism, and perceptions of its impacts, are often diverse, with development often generating gains for some and losses for others. The net effect has been discussed conceptually for many years. This study illustrates an empirical evaluation of it, as well as of gains to tourists. Survey responses to hypothetical ski resort development in Åre, Sweden, indicate that some residents gain from such an expansion while others lose; the net effect on the community is negative over the range of slopes evaluated. Tourists gain from expansion, but their gains are not great enough to outweigh the net losses for residents, such that the welfare change for society as a whole is negative.     

The opening of the North–South divide: Cumulative causation,household income disparity and the regional bonus in Taiwan 1976–2005

During the last decades regional income divergence seems to have reappeared in both developed and developing countries. In Taiwan – a renowned case of growth with equity – regional per capita income was converging until the early 1990s after which it began to diverge. With the help of modeled annual household survey data from 1976 to 2005 we indicate the magnitude of a regional bonus and discuss reasons behind the re-opening of the North–South income divide in Taiwan. Our analysis suggests that this process is a consequence of cumulative causation connected to the advent of the rise of ICT industry in conjunction with changes in Taiwan's political economy which provided relatively more advantageous economic opportunities for the industrial structure of the leading region.     

Explaining the choice of accounting standards in municipal corporations: Positive accounting theory and institutional theory as competitive or concurrent theories

Municipal corporations exist in an institutional twilight area, being both private and public, a characteristic, which presumably would be reflected in their choice of accounting standards. The literature of accounting choice does not, however, live in a twilight area, but is fragmented into two main divisions: positive accounting theory (PAT) and institutional theory (IT); only in a very few cases do the theories meet or cross-fertilize. We use both theories in this paper and derive hypotheses from them to explain accounting choices made by municipal corporations. Through testing the hypotheses on a sample of 545 Swedish municipal corporations, we indicate the empirical relevance of both PAT and IT. We conclude by suggesting an integrative approach of PAT and IT in an eclectic alternative.     

‘Because of poverty,we had to come together’: collective action for improved food security in rural Kenya and Uganda

Agricultural productivity in East African smallholder systems is notoriously low and food production faces multiple challenges, including soil degradation, decreasing land availability, poor market integration, disease burdens and climate change impacts. However, recent evidence from an in-depth study from two sites in Kenya and Uganda shows signs of new social dynamics as a response to these multiple stressors. This paper focuses on the emergence of local social institutions for collective action, in which particularly women farmers organize themselves. Although previous research on collective action has largely focused on common-pool resource management, we argue that collective action is one potential pathway to livelihood and sustainability improvements also in a setting of private land ownership. Trust building, awareness raising and actions to improve livelihood security through risk sharing and pooling of labour and other limited assets have given people more time and resources available for diversification, preventative activities, experimentation and resource conservation. It thereby strengthens farmers’ capacity to cope with and adapt to change, as well as contributes to the agency at the local level.     

UML modelling concepts of HAZOP to enhance the ability to identify emerging risks

Unified Modelling Language (UML) has a graphical notation for 13 different types of diagrams and can be used as a general modelling tool. Well-known examples of diagram types are class diagrams for modelling classes that can be instanced into objects, state machine diagrams for modelling states in systems and activity diagrams for modelling process flows. A literature survey shows that UML has been used to model concepts and methodologies of risk assessment and risk management. One example is the Coras Framework. The international standard CEI IEC 61882 Hazard and operability (HAZOP) studies describes concepts for investigating and detecting possible hazards in systems. In CEI IEC 6882, guide words like ‘More’ and ‘Less’ are applied to system parameters to invoke deviations in the system and assess possible hazards due to the deviation from the design intent. In this paper, we have used UML to model concepts of CEI IEC 61882 Hazards and operability studies. Diagrams of UML were used to show dependencies and relations between parts of the target system and concepts of CEI IEC 61882. Extensions of UML are suggested to better capture and display the concepts of CEI IEC 61882, the results of a HAZOP study and emerging risk. These extensions are referred to as UML for emerging risks (UML-ER).
