Poverty Mapping with Aggregate Census Data: What is the Loss in Precision?

Spatially disaggregated maps of the incidence of poverty can be constructed by combining household survey data and census data. In some countries (notably China and India), national statistics agencies are reluctant, for reasons of confidentiality, to release household‐level census data, but they are generally more willing to release aggregated census data, such as village‐ or district‐level means. This paper examines the loss in precision associated with using aggregated census data instead of household‐level data to generate poverty estimates. The authors show analytically that using aggregated census data will result in poverty rates that are biased downward (upward) if the rate is below (above) 50%, and that the bias approaches zero as the poverty rate approaches zero, 50%, and 100%. Using data from Vietnam, it is found that the mean absolute error in estimating district‐level poverty rates is 2.5 percentage points if the census data are aggregated to the enumeration‐area level means, and 3–4 percentage points if the data are aggregated to commune or district level. Finally, the authors propose a method for reducing the error using variances calculated from the census. When this approach is applied to the Vietnam data, this method can cut the size of the aggregation errors by around 75%.     

Friends with benefits: Behavioral and fMRI studies on the effect of friendship reminders on self-control for compulsive and non-compulsive buyers

Does the real or imagined presence of friends invariantly drive consumers to engage in disinhibited behavior, and give in to the “urge to splurge” in the face of consumption temptations? Or might there be situations in which being with friends or even merely thinking of friends or the friendships we have with them can actually improve self-control?In five studies, using a unique combination of controlled experiments examining overt consumer behavior and functional magnetic resonance imaging (fMRI), we propose and show that the extent to which consumers identify a goal conflict between giving in to buying temptations on the one hand and the perceived consequences for maintaining satisfactory relationships with close friends on the other is a critical mediator of whether friendship reminders decrease or increase self-control. We further show that such a goal conflict is most likely for consumers with a chronic, compulsive tendency for uncontrolled, disinhibited acquisition and consumption—for consumers classified as compulsive buyers. For their non-compulsive counterparts, in contrast, acts of acquisition and consumption, even incidental disinhibited ones, are perceived to be less problematic in light of their friendships and hence do not induce a goal conflict to the same extent. Our findings provide insights into social influences on self-control and identify the concept of friendship reminders as a way to reduce a common type of dysfunctional consumer behavior. In addition to enhancing consumer well-being, reducing compulsive buying will substantially reduce handling costs for organizations. Hence, the findings are of academic, societal and managerial relevance.     

Entrepreneurial metacognition: a study on nascent entrepreneurs

This paper contributes to uncovering the role of metacognition in the decision-making process of entrepreneurs. Specifically, we analyze nascent entrepreneurs in their process of start-up development while relying on metacognitive processes. The experiences of a sample of new venture initiatives are explored in two distinct phases, a start-up competition and the subsequent launch of their venture. Following the Gioia protocol, the study contextualizes the process in which social capital reinforces metacognitive processes. This process stimulates nascent entrepreneurs to consider alternatives, such as extending expertise outside the start-up. Moreover, we find that these processes support entrepreneurs and their teams in improving their decision-making processes. The findings support that nascent entrepreneurs rely heavily on the input of others in their start-up creation process, and contribute to new empirical insights about entrepreneurial metacognition. A dynamic model in which these relationships emerge is developed. The study’s results contribute to a better understanding of the antecedents and consequences of metacognitive processes in nascent entrepreneurship.
