DS-optimal designs in one way ANOVA

Characterization and construction of optimal designs using the familiar optimality criteria, for example A-, D- and E-optimality are well studied in the literature. However the study of the Distance Optimality (DS-) criterion introduced by Sinha (1970) has very recently drawn attention of researchers. In the present article, we consider the singularly estimable full rank problem of estimating the full set of elementary treatment contrasts using the DS optimality criterion in the set up of a one way ANOVA model. Using a limit argument it turns out that a CRD in which difference between any two allocation numbers is at the most unity is uniquely DS-optimal. Acknowledgement. We are thankful to Prof. B. K. Sinha for suggesting the problem to us and many helpful discussions with him. We are also thankful to the referees for drawing our attention to the reference of Bischoff (1995) and many helpful comments.     

Minimum wage and restaurant hygiene violations: Evidence from Seattle

We study the association between the minimum wage and food establishment hygiene violations between Seattle (the treated city) and Bellevue (the control city), both cities located in King County and sharing the same health inspection department. An increase in the real minimum wage of $0.25 is associated with an increase of at least 8% in total and less severe (blue) hygiene violation scores for food establishments in Seattle. We find mixed support for the increase in more severe (red) violations. A decline in employment with an increase in minimum wage could be driving the increases in hygiene violations.     

What drives the cross‐country growth and inequality correlation?

Abstract.  We present a neo‐classical model that explores the determinants of growth‐inequality correlation and attempts to reconcile the seemingly conflicting evidence on the nature of the growth‐inequality relationship. The initial distribution of human capital determines the long‐run income distribution and the growth rate by influencing the occupational choice of the agents. The steady‐state proportion of adults that innovates and updates human capital is path dependent. The output elasticity of skilled‐labour, barriers to knowledge spillovers, and the degree of redistribution determine the range of steady‐state equilibria. From a calibration experiment we report that a skill‐intensive technology, low barriers to knowledge spillovers, and high degrees of redistribution characterize the industrial countries with a positive growth‐inequality correlation. A negative correlation between growth and inequality arises for the group of non‐industrial countries with the opposite characteristics. JEL classification: E1, O4     

Redistributive Tax and Growth in a Model with Discrete Occupational Choice

An optimal redistributive tax-subsidy formula is derived for a growth model where income inequality is endogenously driven by an adult's choice of occupation between work and management. Investment in human capital is the engine of growth. The world's stock of exploitable knowledge as well as the economy's average human capital determine the potential rate of return from investment in human capital in an economy. How much available knowledge would be exploited in the economy depends on the proportion of innovators in our model. A redistributive tax reform impacts growth as well as income inequality via its influence over the occupational choice. The optimal redistributive tax rate is path-dependent in the sense that it depends on the initial wealth distribution. The normative implication of the model is that the optimal capital income tax rate could very well be positive if the initial wealth inequality exceeds a threshold. The optimal capital income tax rate depends inversely on the initial wealth inequality.     

Occupational diversification as an adaptation to rainfall variability in rural India

Occupational diversification among household members in rural India is investigated as an adaptation strategy against the risks arising from the variability of local rainfall. Nationally representative household‐level survey data are combined with the coefficient of variation of rainfall constructed based on historical rainfall data at the district level. The analysis finds that high rainfall variability has significant negative effects on the agricultural specialization of within‐household occupational choices. This result is reinforced by the finding that improved access to irrigation, education, credit, roads, and postal services, is associated with a lower occupational diversification within families and a greater specialization of household members in agricultural‐related employment.     

Thinking critically about critical thinking: Assessing critical thinking of business students using multiple measures

Critical thinking is a skill that potential employers expect all graduates to possess. Hence, most business management programs consider critical thinking as an important student learning goal. Unfortunately, there is ambiguity about how to best assess critical thinking, both as a skill and a learning outcome. The authors empirically demonstrate how they measure the critical thinking ability of their students in different settings, and how their critical thinking ability improves as they progress through the business program.     

Understanding the economic dynamics behind growth-inequality relationships

In this paper, a dynamic general equilibrium (DGE) model of growth-inequality relationships, with missing credit markets, knowledge spillover and self-employed agents, is calibrated to New Zealand data. The model explains how two distinct policy shocks involving redistribution and immigration imply, subsequently, two completely opposite outcomes. Agents’ inability to borrow aggravates a negative macroeconomic effect of heterogeneity on growth. Redistribution mitigates that effect but creates microeconomic disincentives on saving and work-effort. Consequently, immigration shocks that perturb variance of efficiency induce a negative growth-inequality relationship, while redistribution shocks, in New Zealand’s case, produce larger fluctuations in incentives than in macro benefits, implying a positive growth-inequality relationship.     

Rationality, path independence, and the power structure

The justification of the requirement of consistency in aggregating individual preferences is to make the choice rational and path independent. This paper shows that a Paretian social choice mechanism that satisfies even the weakest rationality requirement which is related to the principle of some sort of maximization or path independence alone generates an extremely asymmetric power structure, e.g., almost dictatorship. Consequently, some well-known and interesting impossibility results are generalized.     

Unionization and International Market Share Rivalry: A Paradox

Two exporting firms (domestic and foreign) are considered which are symmetric in all respects except that one is unionized while the other faces a competitive labor market. Under free trade the unionized firm has the lower market share. Paradoxically, in the policy equilibrium, the unionized firm has the larger market share. Consequently, the nation hosting the unionized firm has the higher welfare level.     

Regional determinants of life insurance consumption: evidence from selected Asian economies

The life insurance industry in developing Asian economies is under‐developed compared with global standards. The low market penetration is attributed to full or partial government ownership and entry restrictions on foreign insurers. Regulatory changes and adoption of liberal policies have aided the growth of the life insurance industry in the past decade. At the same time, economic and social factors were expected to promote insurance awareness and consumption. In this context, the paper analyses the factors explaining life insurance demand in 12 Asian economies, including economies from the South Asian Association for Regional Cooperation and Association of Southeast Asian Nations regions, as well as China. The results suggest that income, financial depth, inflation, the real interest rate, and the youth dependency ratio are significant determinants of life insurance consumption. Foreign ownership and improved regulations may foster growth. But urbanisation and the literacy rate are among the few determinants found not to have the impact observed in previous studies. The research highlights the limitations of studies using macrodata and contributes to understanding of the growing insurance industry in the region.
