Meta‐Analysis of Coefficient Alpha: A Reliability Generalization Study

Increasing precision of measurement is a goal of scientific advancement, but Nunnally's (1978) .70 benchmark for coefficient alpha (alpha) has remained the omnibus test for reliability for nearly 40 years. This likely arises due to there only being scattered empirical evidence of the degree to which the field has met or surpassed this standard. Using meta‐analytic techniques known as reliability generalization (RG), we cumulate alphas across 36 commonly used individual differences, attitudes, and behaviours from 1675 independent samples (N = 991,588). Our primary finding is that alphas almost always exceed .70 and generally fall above .80. In addition, we identified factors that moderate alpha including the specific measure used, the number of scale items, and the rater. The study provides baseline alphas that can be used for research planning and design; it also offers best practices for RG and notes the benefits of RG for understanding systematic fluctuations in reliability.     

Religiosity,borrower gender and loan losses in microfinance institutions: a global evidence

We examine the impact of religious beliefs on loan repayments in 770 microfinance institutions (MFIs) across 65 countries over the period 2006–2018. We find robust evidence of a negative relationship between religiosity and loan losses in MFIs. We also find that the relationship between religiosity and loan losses is stronger for MFIs in Protestant-dominated countries than in Catholic-dominated countries. Moreover, religiosity improves the operational self-sufficiency of MFIs through a reduction in loan losses. We find that religiosity does not improve the loan repayment behaviour of women borrowers, but it reduces the loan size per borrower. Overall, our evidence suggests that although religiosity reduces loan losses through religiosity-induced lender-risk aversion, it does not improve the loan repayment behaviour of borrowers. We also use several approaches to evaluate our results to the effects of endogeneity.

     

Listing Specialization and Pricing Precision

This paper investigates the relationship between property pricing precision (deviation from an expected property value) and specialization in the listing process by agents. It is hypothesized that financially constrained, risk-averse sellers prefer finer gradations of pricing precision, i.e., less deviation from expected property value, and that a set of agents will rise to meet this preference. The findings in this work indicate that agents specializing in listing properties increase pricing precision. The contributions of this work are twofold: (a) it provides a unique and heretofore uninvestigated metric as its dependent variable, thus allowing for further investigation into the brokerage intermediation process beyond the scope of price and marketing time, and (b) it provides an identifiable agent trait that can allow for a better matching of sellers’ preferences with agents’ abilities.     

Private Property in the Context of Community

The dominant philosophy of private land ownership—that private property exists for the benefit of its owner and that use and ownership should be determined by market forces—is not the only philosophy in the American tradition. Classical republicanism's proprietarian perspective was equally in favor of private property, but held that private property exists for the benefit of society. This article begins by presenting the proprietarian view of private property rights, drawing on the legal scholarship where this perspective has been revived. Next, I use the case of contemporary land reform in Scotland to exemplify the rationale for this perspective. Lastly, I attempt to import the lessons of Scottish land reformers without importing their model, instead considering ways in which private land ownership might be embedded in non‐market institutions in the United States.     

López de Peñalver's Reflexiones : an economic and mathematical approach

Juan López de Peñalver was an engineer and mathematician who trained in Spain, Central Europe and Paris. His Reflexiones sobre la variación del precio del trigo (1812) contained three models of: (1) wages, wheat prices and mortality; (2) transport costs and location; and (3) constant relative prices, which were brought to an international readership in 1961. His complete works were published in 1992. An advocate of political arithmetic and mathematical economics, he was influenced by Canard, Condorcet and Steuart and the economic writings of Lavoisier and Lagrange; a considerable distance separated him from both Adam Smith and J.-B. Say.     

Publication bias in entrepreneurship research: An examination of dominant relations to performance

Publication bias (PB) exists when the published literature is not representative of the population of studies. PB has largely been ignored or dismissed in entrepreneurship research as there is a general belief that only fields entrenched in dominant theoretical paradigms are capable of suffering from PB. We tested this presumption by re-analyzing the results of 15 systematic reviews (i.e., meta-analyses) of entrepreneurial antecedents and firm performance. Using three different tests, we found some degree of PB in all but three of these analyses. Our results belie the contention that entrepreneurship is immune to PB.     

The Urban,Politics and Subject Formation

In contrast to more traditional debates about voting patterns, local versus state administrations, and individual rights and participatory democracy, this article addresses the question of urban politics through an analysis of subject formation. By taking subject formation as the analytical focus, research questions about ‘politics’ shift from traditional ones about local or state government and the development of consensus, for instance, to ones about the constitution of subjects who are governed and govern themselves in particular ways. Using the emergence of two increasingly commonplace subject forms in contemporary China — urban professionals and volunteers — as examples, the article considers how modes of self‐regulation become political problems and also how subjects may be of the urban as well as located in the urban. The problematizations of socialist state planning have led to new governmental rationalities and technologies that not only produced new subject positions, but also new urban spaces, landscapes, economies and lifestyles. From this view, the article is an intervention into discussions about the ‘where’ of urban politics. It also argues that it is critical to examine politics as problematization and normalization if we are to understand what is at stake in the constitution of potential ‘communities of action’.
