The effect of prime age adult mortality on household composition and consumption in rural Ethiopia

Using panel data from Ethiopia covering 1994–1997, we estimate the impact of prime age adult mortality on household composition, household expenditures and dietary diversity. We employed propensity score matching with a difference-in-difference estimator to control for endogeneity of mortality to the outcomes of interest. Households losing a productive adult did not replenish the lost labor, regardless of economic status, sex or status of the deceased adult. With the exception of non-poor households, adult mortality resulted in increased dependency ratios, but did not adversely affect households’ expenditure patterns (total, food and non-food expenditures) regardless of the sex and position of the deceased and the economic status of the households. Although food expenditures were protected, a decline in dietary diversity, especially among the poorest households, reflected increased nutrition insecurity associated with adult mortality.     

Employability and innovative work behaviour in small and medium-sized enterprises

Abstract

The purpose of this study is to cross-validate HRM measurement instruments for employability (individual competence-based approach) and innovative work behaviour within the context of small and medium-sized enterprises (SMEs) further. The sample consisted of 487 pairs of employees and their immediate supervisors who work in 151 SMEs. A multitrait-multimethod analysis was performed, and the results suggest that for both instruments, requirements regarding convergent and divergent validity have been met satisfactorily. Structural Equation Modeling was performed in order to confirm the factor structure of the instruments. Paired-samples comparisons showed that all of the inter-method correlations for the two-source (employee and immediate supervisor) ratings and for both instruments were significantly positive. As for the final part of the cross-validation, multiple regression analyses were performed to demonstrate predictive validity. Depending on the stage of innovative work behaviour, different dimensions of employability appeared to play a significant role, although the effect did not always veer towards the direction expected. Investing in employability enhancement appeared to contribute to innovative work behaviour. The measurement instruments of employability and innovative work behaviour can provide SME managers with effective instruments to be used for performance appraisals, assessments, and employee development tools.     

Risk,Uncertainty and Exchange Rate Behavior in South Africa

This study investigates the role of market sentiment and foreign policy uncertainty in explaining rand price fluctuations using monthly data from 1995M2 to 2017M8. Empirical results from the pair copula analysis indicate no dependence between foreign policy uncertainties and rand returns when market sentiment is controlled for. Furthermore, change in market sentiment seems to drive fluctuations in rand exchange rate suggesting that exchange rate behavior is indeed unpredictable as market sentiment captures both risk and uncertainty. These results are robust across pre- and post-recent financial crisis periods; hence confirming the ability of pair copula to model extreme events.     

Adding value through the mechanization of post-harvest cassava processing,and its impact on household poverty in north-eastern Zambia

This article investigates the impact of adopting a mechanized cassava processing system on household poverty levels in Zambia. An Foster, Greer and Thorbecke (FGT) poverty measure was used to compare poverty levels among households using a mechanized cassava processing system against those households using a nonmechanized process. Based on the FGT poverty measure’s specifications, a significantly lower poverty status of 49% was found among households using the mechanized process when compared to the 58% found among households using the nonmechanized process. The significant factors contributing to these differences in poverty levels include whether households are using a mechanized process or not, the number of years’ schooling among household members, the number of years’ farming experience, household income and membership of associations. The study concludes that the mechanization of cassava processing, particularly if done on the right scale, can transform primary production activities, in turn leading to higher incomes and reduced poverty levels in rural villages. Thus, policies should be introduced aimed at encouraging the promotion of mechanized post-harvest cassava processing technologies among rural households, so as to enhance crop productivity and household income levels, as well as reduce poverty among rural households.     

Age differences in career activities among higher‐level employees in the Netherlands: a comparison between profit sector and non‐profit sector staff

The present study describes age differences in the occurrence of career activities among profit sector and non‐profit sector employees in the Netherlands. Three different types of variables have been studied, i.e. individual, job‐related and organizational variables. Hypotheses have been tested with original survey data from 423 profit sector employees and 136 non‐profit sector employees. The employees are all working in higher‐level jobs in large organizations. Overall, we may conclude from this study that the differences between profit sector and non‐profit sector workers are not consistent at all. For some factors the situation is more advantageous for profit sector employees, whereas for other factors the outcomes point in the opposite direction. Regarding age effects, we have found that, in general, for profit sector employees the differences between starters (20–34 years) and middle‐aged workers (35–49 years) are not univocal, whereas the differences between middle‐aged workers and seniors (over‐fifties) imply that the amount of individual initiatives and organizational activities is less for the latter group of employees. When the three age groups are compared for the non‐profit sector employees, most factors do not vary significantly. For the factors where the F‐test is found to be significant, by and large, the situation regarding the possibilities for a further career development is worst for the seniors.     

Organisational influences upon the development of occupational expertise throughout the career

The present study describes the relationship between four organisational predictor variables and the degree of occupational expertise of higher‐level employees in three different career stages. The factors in question are: social support from immediate supervisor, social support from near colleagues, organisational facilities and attention from immediate supervisor for a further career development. Hypotheses have been tested with original survey data from 420 higher‐level employees and 224 direct supervisors working in large organisations both in the profit and in the non‐profit sector. The results indicate that the focus of attention is, in general, restricted to the employee's present contribution and to the familiar job domain. Activities aimed at enlarging the outlook are virtually non‐existent. That is to say, management has a preoccupation with instrumental leadership, i.e. aimed at the here‐and‐now and less future‐oriented, instead of appropriate people management.

Can the government create a vibrant cluster? Understanding the impact of cluster policy on the development of a cluster

Research has debated to what extent policy measures can facilitate or contribute to the development of clusters. This article contributes to this debate by questioning how the government can create a cluster that is self-organizing and vibrant but also maintain sufficient influence to continue using the cluster as a policy instrument. Taking the perspective of cluster members, the article investigates how members perceive the ambiguous role of the government in a government-supported cluster. It analyses to what extent cluster members value a government-supported cluster and whether they perceive the government as one that facilitates or hinders them in self-organizing the cluster. Empirical evidence is derived from a case study of a French cluster established as a result of a cluster policy initiative and which has recently been required to fulfil a new set of objectives by the same government. The findings suggest that government-supported clusters can self-organize if members are given the opportunity, but with the consequence that it becomes difficult for the government to fully control such clusters. To continue steering the cluster’s development, the government would have to leverage the technology gatekeepers’ power by designing policies that allow gatekeepers to translate government objectives into meaningful objectives for themselves.     

Inflation and Output Growth Dynamics in South Africa: Evidence from the Markov Switching Vector Autoregressive Model

This paper introduces the possibility of asymmetry in the reaction of output growth to inflation shocks in South Africa by making use of the Markov-switching vector autoregressive model. Using quarterly data from 1969Q1 to 2013Q4, the empirical finding suggests that the reaction of output growth to inflation shocks is not only regime dependent but is also contingent on how the monetary authority reacts to such shocks. Two important regimes are identified; the high and low inflation volatility regimes. Consistent with the signal extraction theory, the output effect of inflation shocks is found to be significantly lower in the high inflation volatility regime compared to the low inflation regime.     

Risk assessment for uncertain cash flows: model ambiguity, discounting ambiguity, and the role of bubbles

We study the risk assessment of uncertain cash flows in terms of dynamic convex risk measures for processes as introduced in Cheridito et al. (Electron. J. Probab. 11(3):57–106, 2006). These risk measures take into account not only the amounts but also the timing of a cash flow. We discuss their robust representation in terms of suitably penalised probability measures on the optional σ-field. This yields an explicit analysis both of model and discounting ambiguity. We focus on supermartingale criteria for time consistency. In particular, we show how “bubbles” may appear in the dynamic penalisation, and how they cause a breakdown of asymptotic safety of the risk assessment procedure.
