Human capital inequality and income inequality: testing for causality

This study investigates the causal relationship between human capital inequality and income inequality in case of Pakistan. The annual time series data ranging from 1973 to 2009 is used for econometric analysis. Johanson co-integration and Granger Causality tests are used to confirm the existence of long run relationship and the causal relationship between human capital inequality and income inequality. The results indicate that there is positive relationship between the two types of inequalities in the long run. The estimates of causality test indicate that income inequality causes the human capital inequality but human capital inequality does not cause income inequality. Policy initiatives to reduce income inequality may empower people economically to avail skill building opportunities and accumulate their human capital through access to educational services.     

What makes a good conference? Analysing the preferences of labour economists

Conferences are an important element in the work of researchers, requiring substantial investments in fees, travel expenses and the time spent by the participants. The aim of this paper is to identify the preferences of participants with respect to conference characteristics. Based on a sample of European labour economists, preferences are measured using the vignette approach where participants are asked to choose between hypothetical European Association of Labour Economists (EALE) conferences. We find that the keynote speakers are the most important element in the preference for a conference, followed by the location of the conference. There is substantial heterogeneity in the taste of labour economists especially with respect to location, though the link between preference parameters and measured characteristics like gender, age and seniority is limited. Factor analysis suggests that the variety in preferences can be best described by a latent variable that reflects the weights people put on content versus fun.     

How interethnic marriages affect the educational attainment of children: Evidence from a natural experiment

The allocation of Moluccan immigrants across towns and villages at arrival in the Netherlands and the subsequent formation of interethnic marriages resemble a natural experiment. The exogenous variation in marriage formation allows us to estimate the causal effect of interethnic marriages on the educational attainment of children from such marriages. We find that children from Moluccan fathers and native mothers have a higher educational attainment than children from ethnic homogeneous Moluccan couples or children from a Moluccan mother and a native father.     

How to define and study farmers' management capacity: theory and use in agricultural economics

Textbooks and articles on farm management stress the importance of the management capacity of the farmer with respect to his farm results. However, explicit definitions together with an elaboration of this concept are hard to find. In this article, aspects of management capacity are grouped into: (1) personal aspects, consisting of fanner's drives and motivations, fanner's abilities and capabilities and his biographical facts such as age and education; and (2) aspects of the decision-making process, consisting of practices and procedures with respect to planning, implementation and control of decisions at the farm. Empirical studies on the role of management capacity in relation to farm results are reviewed. Frontier production functions are widely used in recent literature to estimate technical and economic efficiency of farms. However, in explaining differences in efficiency most studies do not go further than adding a biographical variabk (e.g., level of education). This study concludes that a next step would be to include aspects of the decision-making process. Longitudinal on-farm observations, which give possibilities for studying the dynamic aspects of the decision-making, are suggested to further analyze the concept of management capacity.     

Transaction Costs and Cattle Marketing: The Information Content of Seller-Provided Presale Data at Bull Auctions

At sales of breeding bulls, prospective buyers have strong incentives to undertake presale measurement activities. To reduce these transaction costs, sellers often provide information on sale bulls. We examine the information content of two measures of the expected performance of the bulls and find that within a given herd, older, simpler measures of performance contain more information about prices (from buyers' perspectives) than newer, more sophisticated measures known as expected progeny differences, or EPDs. We also find, however, that buyers appear to pay considerable attention to annual changes in herd-average EPD values when comparing animals from different sellers.     

The System of Rice Intensification (SRI): a challenge for science,and an opportunity for farmer empowerment towards sustainable agriculture

Increasing demand for cereals produced from limited natural resources stimulated the Green Revolution in grain crops like wheat and rice. But the gap between potential and actual production continues. Concerns about sustainability, and the social and technical shortcomings of the Green Revolution, have triggered a number of alternative crop production strategies. One, in particular, the so-called System of Rice Intensification (SRI), is attracting attention by governments, civil society organizations and farmers in Asia and elsewhere.     

Partnerships and the private recruitment industry

This article, based on a postal survey and qualitative interview‐based research, examines the relationship between major private recruitment bureaux and their clients in the UK, with particular attention to the recruitment and selection of temporary workers. The private recruitment industry is growing and large bureaux are seeking closer partnership arrangements with clients. Contracts for labour services are being developed on a 'preferred' supplier basis – similar in type to the approach taken for the purchase or supply of goods or components. However, formal preferred supplier contracts with temporary work bureaux were used by only a minority of clients, usually larger organisations or those having projects or workplaces with high volume demand. While such bureaux seek models of relational contracting or partnering, many clients prefer less fully engaged or 'semi‐distanced' relations facilitated by the informal dimensions of inter‐organisational contacts.     

Cannabis use and mental health problems

This paper investigates whether cannabis use leads to worse mental health. To do so, we account for common unobserved factors affecting mental health and cannabis consumption by modeling mental health jointly with the dynamics of cannabis use. Our main finding is that using cannabis increases the likelihood of mental health problems, with current use having a larger effect than past use. The estimates suggest a dose–response relationship between the frequency of recent cannabis use and the probability of currently experiencing a mental health problem.

Trust relations in management of change

Trust is essential for the success of change, but transformational change challenges trust. This paper analyses how trust dynamics develop over time in two Danish manufacturing firms affected by major change programmes. The results show that change creates uncertainty among employees, thereby provoking intense scrutiny of management intentions and a tendency to make interpretations that exaggerate management intentions—with the end result of reduced trust. Management then react similarly with negative interpretations of employee reactions, creating a vicious cycle of reduced trust. The paper proposes a model for how change and trust interact and suggests a managerial strategy for trust repair: Strong management actions that symbolise integrity, competence and benevolence may counteract reduced trust, but if low trust turns into distrust, the result may be a deadlock that both parties find difficult to break.
