The Incidence of Public Spending on Healthcare: Comparative Evidence from Asia

The article compares the incidence of public healthcare across11 Asian countries and provinces, testing the dominance of healthcareconcentration curves against an equal distribution and Lorenzcurves and across countries. The analysis reveals that the distributionof public healthcare is prorich in most developing countries.That distribution is avoidable, but a propoor incidence is easierto realize at higher national incomes. The experiences of Malaysia,Sri Lanka, and Thailand suggest that increasing the incidenceof propoor healthcare requires limiting the use of user fees,or protecting the poor effectively from them, and building awide network of health facilities. Economic growth may not onlyrelax the government budget constraint on propoor policies butalso increase propoor incidence indirectly by raising richerindividuals' demand for private sector alternatives.     

Social business collaboration at the bottom of the pyramid: The case of orchestration

Social business orchestrators (SBOs) help social businesses of various sizes to tackle major societal issues by filling gaps in knowledge and resources. However, research has overlooked these types of collaboration. Situated within a bottom of the pyramid context in Bangladesh, the current study sheds light on the process of value creation for SBO–social businesses partnerships by comparing different collaboration partners. Multiple case study research through the lens of the relational view were used to ask how SBOs facilitate value creation in social businesses by flexibly adapting resource inputs and governance mechanisms to the specific endowment and size of partners; this approach was informed by interviews and field note analyses. The combined deductive–inductive analysis enhances knowledge of idiosyncrasies of SBO–social business collaborations. Our study draws attention to the role of large orchestrators, whose model could be scaled and transferred to other world regions, including industrialised countries.     

Modeling and forecasting trading volume index: GARCH versus TGARCH approach

Volatility has been described as an indicator of uncertainty which has implications for investment decisions, risk management as well as monetary policy. This paper investigates the pattern of volatility in the daily trading volume index of Hong Kong stock exchange. The empirical evidence provided in this paper suggests that TGARCH specification is superior to GARCH specification. This is particularly important when one is dealing with the case of asymmetric information that captures the leverage effect of the volatile stock market.     

A Pinch or a Pint? Evidence of Pesticide Overuse in Bangladesh

In a recent survey of 820 rice, potato, bean, eggplant, cabbage, sugarcane and mango farmers in Bangladesh, over 47% of farmers were found to be overusing pesticides. With only 4% of farmers formally trained in pesticide use or handling, and over 87% openly admitting to using little or no protective measures while applying pesticides, overuse is potentially a great threat to farmer health as well as the environment. Pesticide overuse was initially modelled using a three‐equation, trivariate probit framework with health effects and misperception of pesticide risk as endogenous dummy variables. Significance tests revealed that health and misperception were not endogenous to overuse, suggesting a bivariate probit model for health effects and misperception and a separate probit model for overuse. Health effects were found to be a function of the amount of pesticides used in production, nutritional status and income, while misperception of pesticide risk was determined by health impairments from pesticides and the toxicity of chemicals used. Pesticide overuse was significantly explained by variation in misperception, income, farm ownership, the toxicity of chemicals used, crop composition and geographical location. These results highlight the necessity for policymakers to design effective and targeted outreach programmes which deal specifically with pesticide risk, safe handling and averting behaviour. Ideally, the approach would be participatory in nature to address key informational gaps, as well as increasing: farmers’ awareness. The results also point to specific crops and locations experiencing a higher prevalence of overuse. Focusing efforts on these crops and geographical areas may have the most measurable effects on pesticide overuse.     

A time series analysis of causality between aggregate merger and stock prices: the case of Canada

It is widely agreed that a positive relationship exists between measures of aggregate merger activity and measures of stock market performance, at least for the USA. Evidence from other countries is relatively sparse. in this paper we pursue the causality question using Canadian data. Most of the previous studies used only a bivariate system (merger and stock prices). We have extended the analysis to trivariate system (merger, stock prices and interest rate) to better reflect the capital market conditions argument for changes in merger activity. The results suggest a bidirectional causality between mergers and stock prices.     

Water pollution abatement by Chinese industry: cost estimates and policy implications

Factory-level data are used to estimate water pollution abatement costs for Chinese industry. Joint abatement cost functions are utilized which relate total costs to treatment volume and the simultaneous effect of reductions in suspended solids, chemical oxygen demand, biological oxygen demand and other pollutants. Tests of alternative functional forms suggest that a very simple (constant elasticity) model fits the data as well as a complex (translog) model, permitting sophisticated policy experiments with relatively simple calculations. From the results, the cost-effectiveness of current pollution control policy in China is analysed. Basic conclusions are (1) The benefits of stricter discharge standards should be weighed carefully against the costs. For the sample of 260 factories, a shift across the existing range of standards entails a present-value difference of US$330 million in abatement costs. (2) Emissions charges as low as US$1.00/ton would be sufficient to induce 80% abatement of suspended solids for cost-minimizing factories. Charges of US$3, US$15 and US$30 per ton would be sufficient to induce 90% abatement of TSS, COD and BOD. (3) The current regulatory system provides an economic incentive to abate by charging a levy on pollution in excess of the standard. However, the results suggest that changing to a full emissions charge system would greatly reduce overall abatement costs. For the 260 factories in the sample, the current overall abatement rate could be attained under a charge system at a reduced annual cost whose present value is US$344 million.     

A panel data analysis of the growth effects of remittances

Many development economists believe that remittances by the migrant workers are an important source of funds for long run growth. Therefore, recent studies have investigated the growth effects remittances in the recipient countries but reached different conclusions. This paper analyses the strength of these effects with a common data set with alternative specifications and estimation methods. Our results show that the direct growth effects of remittances are insignificant. However, remittances may have small indirect growth effects.     

Diverging Stories of “Missing Women” in South Asia: Is Son Preference Weakening in Bangladesh?

ABSTRACT

South Asia is a region characterized by a culture of son preference, severe discrimination against daughters, and excess levels of female mortality, leading to what Amartya Sen called the phenomenon of “missing women.” However, the onset of fertility decline across the region has been accompanied by considerable divergence in this phenomenon. In India, improvements in overall life expectancy have closed the gender gap in mortality rates among adults, but persisting gender discrimination among children and increasing resort to female-selective abortion has led to growing imbalance in child sex ratios and sex ratios at birth. In Bangladesh, by contrast, fertility decline has been accompanied by a closing of the gender gap in mortality in all age groups. Using quantitative and qualitative data, this study explores changing attitudes toward sons and daughters in Bangladesh to explain why the phenomenon of “missing women” has played out so differently in these two neighboring countries.     

Are the Direct and Indirect Growth Effects of Remittances Significant?

Development economists believe that migrant workers’ remittances are an important source of funds for long‐run growth. Therefore, recent studies have investigated the growth effects of remittances but reached different conclusions. In these studies, the rate of growth of output is simply regressed on both remittances and the channels through which remittances affect growth. Thus, no distinction has been made between the indirect and direct growth effects of remittances. Such regressions may give unreliable estimates because the channels may also capture some growth effects of remittances, making the growth effects of remittances insignificant. In this study, we make a distinction between the indirect and direct growth effects of remittances. Our model is estimated with panel data of 40 high remittance recipient countries with the system generalized method of moment. We found that remittances have no direct growth effects but they have small indirect growth effects.
