Bioeconomics of some nonhuman and human societies: new institutional economics approach

New institutional economics (NIE) has been very successful in explaining the role of institutions such as the firm, money, and contract law in facilitating production and exchange in human societies. In this paper, I will show that the NIE approach, which so far has been used by economists to analyze institutions and organizations in human society, including the ethnically homogeneous middleman groups, can also be extended to explain the high degree of cooperation and coordination of activities of honeybees, ants, and schooling fish. In addition, the paper emphasize the importance of identity in nonhuman and human societies in eliciting cooperation and in detecting cheaters or fakers. This paper thus contribute to the integration/consilience of economics and biology by providing a more unified view of aspects of the bioeconomics of nonhuman and human societies.     

Formulating Hypotheses Graphically in Social Research

This article explores the proposition that the appropriate use of suitable forms of graphic communication can improve the formulation and presentation of hypotheses in quantitative social science research. The creative nature of scientific diagrams is discussed and the technological advances in computer graphic media are seen as part of a visual revolution which is markedly changing not only the way we see things but also the way we think and do things today. Brief historical views on the use of hypotheses and diagrammatic languages in science are given. The restricted use of graphic communication tools in social research academic documents is discussed and the importance of using well-designed data graphics in the production and transmission of scientific knowledge is highlighted. Hypotheses are conceptualised and their importance within social research is emphasised. A methodological approach for formulating hypotheses graphically is proposed based on the use of three types of language: notation, statement (ordinary language) and diagram. Some criteria are suggested for the selection of diagram type dependent on the related variables. Several examples are given covering the different models proposed.     

Women's Leisure as Political Practice: A Feminist Analysis of Orange Is the New Black

ABSTRACT

The purpose of this article is to examine representations of women's leisure portrayed on the popular Netflix television series Orange Is the New Black (OITNB). Using a feminist lens rooted in the notion of interconnectivity, we draw on four television tropes proposed by Pozner (2010 Pozner, J. L. (2010). Reality bites back: The troubling truth about guilty pleasure TV. Berkeley, CA: Seal Press. [Google Scholar]) that are commonly used to depict women characters on television to analyze representations of women's leisure in the first three seasons of OITNB. Our analysis reveals the complex and messy ways representations of women's leisure on OITNB can be used to discipline, reproduce, but also challenge power relations associated with common media tropes, acting as a form of political practice. We conclude by considering the implications of how these representations can influence the lives of women consuming this media content as part of their leisure.     

Has Trade Become More Responsive to Income? Assessing the Evidence for US Imports

This study tests the stability of a standard equation for aggregate US imports over the period 1975–2011. It finds evidence of significant parameter instability, though its dating varies with the equation specification and diagnostic. Nonetheless, the analysis finds a significant rise in the long-run income elasticity that is robust across most break dates and specifications. The increase in the long-run income elasticity is consistent with shifts in the composition of aggregate imports toward capital and consumer goods. There is further evidence that vertical specialization may be behind both the structural instability and the apparent rise in the income elasticity of aggregate US imports.     

What's in Your 403(b)? Academic Retirement Plans and the Costs of Underdiversification

Sponsors of defined contribution retirement plans typically limit the investment choices of plan participants to a small number of investment managers and a limited number of investment vehicles. Such restrictions may limit excessive risk-taking by participants but also may preclude opportunities for efficient diversification. Many college and university 403 (b) plans have restricted investment choices to the retirement annuities offered by TIAA-CREF, the current manager of over half of all 403(b) contributions. Using 10 years of historical data, we study the efficiency of this TIAA-CREF opportunity set relative to a larger set that includes several standard index funds. Extrapolations must be interpreted -with caution. Assuming optimal rebalancing, depending on loss aversion and diversification constraints, the historical sample of returns implies that over a 20-year remaining work life, an employee -with an expanded menu that includes standard index funds could gain over 40% in terminal wealth compared to one who is restricted to TIAA-CREF retirement annuities. Even when a naive diversification strategy of equally weighting (1/n) all available funds is used, the expandedmenu outperforms the restricted portfolio by more than 25% over20years. These differences generally are significant at conventional levels based on parametric and nonparametric testing and do not appear to result from idiosyncratic market performance durinz the sample period.     

Banking relationships and access to equity capital markets: Evidence from Japan’s main bank system

We study the role of banking relationships in IPO underwriting. When a firm in Japan goes public, it can engage an investment bank that is related through a common main bank, or can select an alternative investment bank. The main bank relationship can be an efficient way for the investment bank to acquire information generated by the main bank, but may give rise to conflicts of interest. We find that main bank relationships give small issuers increased access to equity capital markets, but that issuers of large IPOs often switch to non-related investment banks that are capable of managing large offerings. While investment banks seek to exploit bargaining power with related issuers, issuers respond to expected high issue cost by switching to non-related investment banks. The net result is that total issue costs through related and non-related investment banks are similar. With respect to aftermarket performance and use of proceeds, we find no evidence of conflict of interest or self-dealing for either the main bank or the investment bank.     

Inherent risk: An investigation of auditors' judgments

The assessment of inherent risk is a judgment required of auditors by Statement on Auditing Standards 47 (Auditing Standards Board, AICPA, New York, 1983) that normatively affects the scope of work performed on audit engagements. This study explores the judgments of auditors concerning inherent risk in inventory. Four inherent risk factors were examined: turnover of the controller, financing pressure, the amount of complexity of overhead in inventory, and the quality of the personnel responsible for the inventory calculation. A human information processing approach employing ANOVA was utilized to determine the relative reliance on these factors in the inherent risk judgments of 65 practicing auditors. Correlation techniques were used to measure consensus, reliability, and self-insight.The results suggest that although all four inherent risk factors were important to auditors, quality of personnel was the most significant. Reliability was slightly lower than in previous research, but was still fairly high. Self-insight was moderate.     

A Note on Affordability and the Optimal Share Price

Despite the increase in institutional ownership, decreased trading costs, and increased real personal savings, we find that the average stock price is lower today than it was in the 1920s. In the aggregate, the propensity to split is a function of recent market performance, personal savings, and the desirability of appearing to be a small firm. Our results indicate that, after decades of inflation and the average stock price falling, splitting stocks to return to an affordable trading range must be rejected as an explanation. This suggests that other economic forces are behind splits, whether traditional or behavioral in nature.
