‘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).     

The Precursor Role of Cooperation,Coordination, and Relationship Assets in a Relationship Model

ABSTRACT

Purpose: The primary purpose of this study is to test the importance of activity-oriented precursors in a relationship model. This study supports the theoretical view that firms create trust and knowledge through activities and these activities make a commitment decision less risky (Johanson & Vahlne, 2009). The secondary purpose of this study is to collect and examine data from interorganizational relationships in both Sweden and the United States. By including data from two countries, results will be more generalizable. Results can also lead to several managerial implications.

Methodology/approach: This study focuses on a sample of distributors from both the United States and Sweden. One hundred sixty-one usable surveys were returned from the U.S. survey, for a response rate of 27%. One hundred twenty-four usable surveys were returned from the Swedish survey, for a response rate of 21%. The PLS-SEM method was used to examine the model’s constructs.

Findings: Similar to past research results show that trust and commitment have a direct positive influence on satisfaction, and that trust also has a direct positive influence on commitment. However, this study uniquely supports four out of six newly tested hypotheses. Both cooperation and relationship assets have a direct positive influence on commitment. Cooperation has a direct positive influence on trust and commitment. Relationship assets have a direct negative influence on trust but a direct positive influence on commitment. Surprisingly, two hypotheses were not supported: Coordination did not have a significant relationship with either trust or commitment.

Research implications: Managers who want to achieve a satisfactory relationship based on trust and commitment need to prioritize their attention toward cooperation. They should also be aware that participation in joint activities (i.e., coordination and relationship investments) does not guarantee higher levels of trust or commitment in the relationship. It is the quality of the joint activities and the how dependent firms are on each other and not just participation in joint activities that are likely to create higher levels of trust or commitment. The quality of coordination and manageable levels of dependence may counteract the higher costs associated with joint activities compared to the costs associated with cooperation. Managers may be wise to not make major commitments to other firms unless high quality joint activities have created knowledge and trust between firms. Originality/value/contribution: The model adds the joint activity-oriented antecedents associated with collaboration which is essential to a successful relationship. Because of the high failure rate of collaboration may be due to cooperation and coordination failures and because these two constructs are underspecified in interorganizational research, this study is unique in examining activity-oriented antecedents in a trust/commitment model of relationship satisfaction in a cross-cultural context (i.e., with U.S. and Swedish samples).     

Willingness to Pay and Sensitivity to Time Framing: A Theoretical Analysis and an Application on Car Safety

Stated preference (SP) surveys attempt to obtain monetary values for non-market goods that reflect individuals’ “true” preferences. Numerous empirical studies suggest that monetary values from SP studies are sensitive to survey design and so may not reflect respondents’ true preferences. This study examines the effect of time framing on respondents’ willingness to pay (WTP) for car safety. We explore how WTP per unit risk reduction depends on the time period over which respondents pay and face reduced risk in a theoretical model and by using data from a Swedish contingent valuation survey. Our theoretical model predicts the effect to be nontrivial in many scenarios used in empirical applications. In our empirical analysis we examine the sensitivity of WTP to an annual and a monthly scenario. Our theoretical model predicts the effect from the time framing to be negligible, but the empirical estimates from the annual scenario are about 70 % higher than estimates from the monthly scenario.     

Formal microlending and adverse (or nonexistent) selection: a case study of shrimp farmers in Bangladesh

Microcredit schemes have become a popular means of improving smallholders’ access to credit and making long term investment possible. However, it remains to be explored whether the current microcredit schemes are more successful than earlier formal small scale lending in identifying successful borrowers. We studied shrimp farming in a rural region in Bangladesh where formal microlending is well established, but where more expensive informal microlending coexists with the formal schemes. Farmers – both those who exclusively use formal loans and those who also use informal loans – remain credit-constrained; both types overutilize labour in order to reduce the need for working capital. However, the credit constraint is actually milder for the informal borrowers: the implicit shadow price of working capital is substantially higher in the group that only takes formal loans than in the group that also uses informal loans. These results suggest that informal lenders – with their closer ties to the individual farmers – remain more successful in identifying those smallholder farmers that are most likely to use the borrowed funds successfully. Informal lenders have an information advantage that formal microlenders lack: the latter need to find routes to access this information in order for formal microcredit schemes to succeed.     

The economics of on-farm processing: model development and an empirical analysis

Recent trends in the developments of the Common Agricultural Policy suggest an increasing attention towards rural development issues. On-farm processing may offer an alternative for diversification, income generation and rural development in the event of increasingly deregulated agricultural markets. In this study, the economics of on-farm processing for the case of the Swedish potato industry is examined. An interregional partial equilibrium model is developed. Various stages of the potato marketing chain are explicitly modelled. It is empirically demonstrated that, in some regions, on-farm processing is a part of a socially optimal industry structure. Furthermore, it is shown that on-farm processors are more robust towards import competition than bulk product producers. Hence, the results support the notion that small scale processing may contribute towards satisfying some of the objectives of an effective rural development agenda.     

Which News Moves the Euro Area Bond Market?

Abstract. This paper explores a long dataset (1999–2005) of intraday prices on German long-term bond futures and examines market responses to major macroeconomic announcements and ECB monetary policy releases. German bond markets tend to react more strongly to the surprise component in US macro releases compared with aggregated and national euro area and UK releases, and the strength of those reactions to US releases has increased over the period considered. We also document that the numbers of German unemployed workers consistently have been known to investors before official releases.     

Structural Change, Competition, and Job Turnover in Swedish Manufacturing, 1964–96

The rate of interindustry job turnover in Swedish manufacturing seems to be driven by the dispersion of profit changes among industries. Shifts in international competitiveness among industries played a central role for explaining this pattern. The rate of intraindustry job turnover among plants has been higher in industries with many small plants, low profit margins, and high import penetration.     

Determinants of efficiency of vegetable production in smallholder farms: The case of Ethiopia

Improving production efficiency remains as a plausible means of increasing productivity when resource reallocation, and the creation and adoption of new technologies are limited. Technical, allocative and economic efficiencies are derived from a sample of smallholder vegetable farmers in Ethiopia using parametric and non-parametric methods. The results reveal that the two methods yield similar estimates and the existence of substantial inefficiencies in production as well as efficiency differentials among farmers. The analysis of the determinants of efficiency of vegetable production using regression models show that low asset ownership, illiteracy, large family size, inadequate extension contacts, small farm size, age, low off/non-farm income and high consumer spending are the major socio-economic factors causing inefficiency of vegetable production in the study areas. A comparison of the market-driven (vegetables) with the whole-farm (crops and livestock) production efficiency indicates that lower economic efficiency scores for the former might be related to the limited access to capital markets, high consumer spending, and large family size.     

Willingness to Pay and QALYs: What Can We Learn about Valuing Foodborne Risk?

This paper examines the value of reducing foodborne risk. Previous research on the valuation of health risk has been dominated by the study of mortality risk. However, in most cases foodborne illnesses are non‐fatal, so we focus on individuals' preferences for reducing morbidity risk, while also including a realistic, if remote, chance of death. We use a contingent valuation method on a Swedish sample and we estimate a value of a statistical illness consistent with previous findings in the literature. We also examine how willingness to pay (WTP) varies with the expected change in quality‐adjusted life years (QALYs) and estimate the WTP per QALY. We find that WTP increases with, though less than proportionally to, a change in QALYs. However, our results also suggest that respondents may have found it difficult to evaluate compound risks of both morbidity and mortality simultaneously.
