Agricultural commercialisation models,agrarian dynamics and local development in Ghana

The renewed commitment of African states to modernising agriculture has reignited longstanding debates about different models of agricultural commercialisation. Which forms of commercialisation models will reduce land dispossession and the impoverishment of smallholders, and transform smallholder agriculture and the wider economy? Of the three broad models of agriculture commercialisation in this debate – plantation, contract farming and medium-scale commercial farming – contract farming has been identified as central to the future of Africa’s commercial agriculture. This paper provides empirical evidence from Ghana on the impacts of these three models on land, labour/employment, livelihoods and local economic linkages. Our findings show that the plantation and the commercial farming areas have highly commercialised land relations, land scarcity and high land prices, compared to the outgrower area where traditional systems of accessing land still dominate, enabling families to produce their own food crops while also diversifying into wage labour and other activities. Food insecurity was highest in the plantation area followed by the commercial area, but lowest in the outgrower area. Here, semi-proletarianised seasonal workers combine self-provisioning from their own farms with wages, and this results in better livelihood outcomes than for permanent workers in plantations and commercial farms. Due to the processing units in the plantation and the outgrower models, they provided more employment. However, the casualisation of labour and gender discrimination in employment and access to land occur in all three cases. All three models generated strong economic linkages mainly because they combined attributes such as processing, provided markets for nearby farmers, induced state infrastructural development and diffused technology in competitive ways. The effects of the models on household and local development are coproduced by their interaction with pre-existing conditions and wider national economic structures.     

Rent-seeking with asymmetric valuations

This paper analyzes Tullock's rent-seeking game with asymmetric valuations for a variable range of the returns to scale parameter. A necessary and sufficient condition for a unique pure strategy Nash equilibrium is established. Equilibrium effort and expected profits are determined and subjected to comparative statics analysis. Increasing the underdog's valuation induces both players to increase their efforts. Increasing the favorite's valuation increases his effort but decreases the effort of the underdog. Expected profits increase with a player's valuation but decreases with the valuation of the competitor. The impact of the returns to scale parameter is also analyzed.     

The Impact of Social Media Political Activists on Voting Patterns

This paper investigates how social media affects general voting patterns. Unlike previous studies investigating whether citizens’ use of social media affects political participation, this paper considers the connections that social media users have with political activists on social media, and how this connectedness influences general voting patterns, using data from Ghana. With contemporary theoretical perspectives and exploratory techniques, trends from past literature are presented, from a social media-based propagated survey with 420 valid responses. Structural equation modeling was used to test the conceptual model, which demonstrates that the connectedness with political and social media activists is significant and positively influences modifications in voting patterns. Online political participation and political affect also present an effect on voting patterns. The relationship between connections with social media political activists and online political participation is significant, as indicated by a strong covariance observed in the model. The results of the multigroup analysis also indicate some cultural and social issues to shape the phenomena for further investigation.

     

Correlates and predictors of juvenile delinquency in Ghana

Research on juvenile delinquency has focused almost exclusively on western societies with the consequence that very little is known about delinquency and its associated factors outside this context. The aim of this study is to investigate correlates and predictors of juvenile delinquency in Ghana, a developing country. Analysis of data from a sample of 264 boys showed theft as the most common juvenile offense in Ghana. Individual factors were strongly related to juvenile delinquency compared with family factors and perceived neighborhood condition. The best predictor of juvenile delinquency was academic difficulties. Most childrearing variables failed to predict delinquency in Ghana. The findings indicate not only similarities but also important differences particularly with regard to conceptualization and relation between parental childrearing and delinquency.     

Pitfalls in the Use of Time Series Methods to Study Deterrence and Capital Punishment

Objectives

Evaluate the use of various time series methods to measure the deterrence effect of capital punishment.

Methods

The analysis of the time series approach to deterrence is conducted at two levels. First, the mathematical foundations of time series methods are described and the link between the time series properties of aggregate homicide and execution series and individual decision making is developed. Second, individual studies are examined for logical consistency.

Results

The analysis concludes that time series methods used to study the deterrence effects of capital punishment suffer from fundamental limitations and fail to provide credible evidence. The common limitation of these studies is their lack of attention to identification problems. Suggestions are made as to directions for future work that may be able to mitigate the weaknesses of the current literature.

Conclusions

Time series studies of capital punishment suffer from sufficiently serious identification problems that existing empirical findings are compatible with either the presence or the absence of a deterrent effect.
