Trade unions vs. statistical discrimination: Theory and application to post-apartheid South Africa

A simple model of statistical discrimination is analyzed, which captures some stylized facts of the South African labor market. It shows that this type of discrimination disappears when the wage rates are determined by efficient bargaining between a representative firm and a union, with endogenous membership. This may explain why the wage gap between Black and White workers in post-apartheid South Africa is smaller among unionized workers than among non-unionized ones.     

Cost effectiveness of benralizumab for severe,uncontrolled oral corticosteroid–dependent asthma in Sweden

Abstract

Aim: We investigated cost effectiveness of benralizumab vs. standard of care (SOC) plus oral corticosteroids (OCS) for patients with severe, eosinophilic OCS-dependent asthma in Sweden.

Materials and methods: A three-state, cohort-based Markov model of data from three Phase III benralizumab clinical trials (ZONDA [NCT02075255], SIROCCO [NCT01928771], and CALIMA [NCT01914757]) was used to assess the incremental cost-effectiveness ratio of benralizumab vs. SOC plus OCS. Health outcomes were estimated in terms of quality-adjusted life-years (QALYs). The model included costs and disutilities associated with extrapolated OCS-related adverse events. Patients with severe asthma were defined as those receiving OCS ≥5?mg/day.

Results: Benralizumab demonstrated a cost-effectiveness ratio vs. SOC plus OCS of 2018 Swedish Kronor (SEK) 366,855 (€34,127) per QALY gained, based on increases of 1.33 QALYs and SEK 488,742 (€45,344) per patient. Benralizumab treatment costs contributed most to incremental costs. The probability of benralizumab’s being cost-effective with willingness-to-pay (WTP) thresholds between SEK 429,972 (€40,000) and SEK 752,452 (€70,000) ranged from 75% to 99%.

Limitations: Potential limitations of these analyses include the use of combined data from three different clinical trials, a one-way sensitivity analysis that did not include mortality and transition estimates, and Observational & Pragmatic Research Institute (OPRI) data from the UK as a proxy of the Swedish health care system.

Conclusions: The results of these analyses demonstrate that benralizumab has a high probability of being cost-effective compared with SOC plus OCS for a subgroup of patients with severe, eosinophilic asthma receiving regular OCS treatment and may support clinicians, payers and patients in making treatment decisions.     

Assessing the Impact of District Primary Education Program in India

We examine the impact of India's District Primary Education Program (DPEP) introduced in the mid‐1990s. We exploit the fact that the DPEP was targeted towards primary school age children and was introduced in phases to different districts in India, and many of the districts never got the program to implement a difference‐in‐difference strategy to find the causal impact of the program on probability of attended primary school, probability of completed primary education and years of schooling. We find that the DPEP program increased the probability of attended primary school and completed primary school by about 2 percentage points. Similarly, the program increased the years of schooling by 0.16 years.     

Board Committee Meetings and Firm Financial Performance: An Investigation of Australian Companies

This article examines how the frequency of board committee meetings impacts on Australian firms' financial performance. Data were collected from 118 Australian listed companies – including 26 financial firms and 92 nonfinancial firms – for the period 1999–2007. Analysis of that data shows that the frequencies of audit committee meetings and remuneration committee meetings are positively and significantly associated with return on equity and return on assets. The frequencies of risk committee meetings do not show any significant effects on the financial performance of Australian firms. Estimated results are found to be robust after controlling for internal as well as external governance mechanisms that might affect Australian firm performance.     

An Analysis of Tax Incentives to Attract FDI in Bangladesh： An Empirical Study

The purpose of the study is to understand whether it is still viable to use tax incentives to attract foreign direct investment （FDI） considering their effectiveness and costs to the country, and if not, what should be the alternative, effective, and viable means of promoting the vital FDI inflow. The study investigated various incentives provided by BOI, and other relevant sources available as secondary sources. However, the multinational enterprises （MNEs） are not attracting for investment in Bangladesh always with tax incentives and there are alternative means of attracting FDI such as direct financial grants, subsidies loan guarantees, etc. This paper focuses on tax incentives and the debate against the effectiveness and efficiency in attracting FDI.     

Explaining Caste Differences in Private School Attendance

Using a nationally representative education survey, we explore caste differences in private school attendance in India. We find lower private school attendance among the disadvantaged castes—Scheduled Castes (SCs), Scheduled Tribes (STs) and Other Backward Castes (OBCs)—when compared with the non‐disadvantaged group (non‐SC/ST/OBC). Controlling for geographical location, household and individual level factors reduces the gaps in private school attendance considerably; however, the gaps remain quite large. We find that variation in parental education and household consumption expenditure explains a significant proportion of the observed gaps. For ST students, geographical location remains important in explaining the gap in private school attendance.     

A tale of two states: asymmetries in the UK small,value and momentum premiums

This article performs comparative analysis of the asymmetries in size, value and momentum premium and their macroeconomic determinants over the UK economic cycles, using Markov switching approach. We associate Markov switching regime 1 with economic upturn and regime 2 with economic downturn. We find clear evidence of cyclical variations in the three premiums, most notable being that in the size premium, which changes from positive in expansions to negative in recessions. Macroeconomic indicators prompting such cyclicality the most are variables that proxy credit market conditions, namely the interest rates, term structure and credit spread. Overall, macro factors tend to have more significant impact on the three premiums during economic downturns. The results are robust to the choice of information variable used in modelling transition probabilities of the two-stage Markov switching model. We show that exploiting cyclicality in premiums proves particularly profitable for portfolios featuring small cap stocks in recessions at a feasible level of transaction costs.
