Effect of public programs on family size,child education and health

"A bulk of public resources in developing countries is devoted to the subvention of population control and health investments. The effects of these programs have been evaluated in this study with household and community data from Bangladesh. The results suggest that subsidy on family planning and secondary school would be most effective in the achievement of harmonious goals of reducing fertility and mortality and fostering investments in child education."     

Epidemiological patterns of suicide terrorism in the civilian Pakistani population

In this study, we assessed the epidemiological patterns of suicide terrorism in the civilian population of Pakistan. Information about suicide terrorism-related events, deaths and injuries was extracted from the South-Asian Terrorism Portal (SATP) for the period from 2002 to October 2009. Of 198 events, civilians were involved in 194 events. Civilians accounted for 74.1% (N?=?2017) of those who died and 93.8% (N?=?6129) of those who were injured. In nine districts, mortality rates were more than one death per 100,000 inhabitants per year. The yearly trend showed a shift of attack targets from foreigners and sectarian targets in 2002-2005 to security forces or general public in 2006-2009. Attacks on public installations (mosques) or political gatherings resulted in a significantly greater (P?≤?0.02) number of deaths (22 vs. 8) and injuries (59 vs. 24) per event compared with security installations. These results show that prevention might focus on political negotiation with armed groups and that appropriate measures should be taken to protect mosques and political gatherings.

How justified is abandoning money in the conduct of monetary policy in Australia on the grounds of instability in the money‐demand function?

The role of money in the design and conduct of monetary policy has reemerged as an important issue in both advanced and developing economies, especially since the 2007 global financial crisis. A growing body of recent literature suggests that the causal relationship between money supply growth and inflation remains intact across countries and over time and that this relation is not conditional on the stability of the money‐demand function or whether money is endogenous or exogenous. Moreover, critical for a rule‐based monetary policy is the presence of a long‐run stable money‐demand function, rather than a short‐run money‐demand model that may exhibit instability for many reasons, including problems with estimating a money‐demand model with high‐frequency data. Provided that a stable money‐demand function exists, it could be useful to establish long‐run equilibrium relations among money, output, prices, and exchange rates, as the classical monetary theory suggests. Within this analytical framework, this paper addresses the question of whether money has any role in the conduct of monetary policy in Australia. The conventional wisdom is that the money‐demand function in Australia has been unstable since the mid‐1980s due to financial deregulation and reforms; this led to a change in the strategy of monetary policy for price stability in the form of inflation targeting that ignores money insofar as inflation and its control are concerned. This paper reports empirical findings for Australia, obtained from a longer quarterly data series over the period 1960Q1–2015Q1, which suggest that instability in the narrow‐money‐demand function in Australia was primarily due to the exclusion of variables which have become important in the deregulated environment since the 1980s. These findings are confirmed by an expanded form of the narrow‐money‐demand function that was found stable over the past two decades, although it experienced multiple structural breaks over the study period. The paper draws the conclusion that abandoning the monetary aggregate as an instrument of monetary policy in Australia, under a rule‐based monetary policy such as inflation targeting, cannot be justified by instability in the money‐demand function or even by lack of a causal link between money supply growth and inflation.     

Minimising emergency response time of ambulances through pre-positioning in Dhaka city,Bangladesh

This study conducted a large-scale survey in Dhaka, Bangladesh; the survey involved 95 major hospitals, more than 3000 emergency room patients, and 2 of the largest ambulance operators. Currently, most ambulances are parked within the vicinity of hospitals and are either dispatched or fetched by the acquaintances of the patient on demand, resulting in lengthy round trips. Reducing the response time of ambulances would certainly improve the emergency service, and pre-positioning of the ambulances could be a solution to reducing the response time. This study used two approaches to address the problem. First, the location-allocation problem was solved to find the optimal number of ambulance locations by maximising the demand coverage. Second, separate location-allocation for the peak and off-peaks, using K-means clustering, was applied to systematically optimise the ambulance positioning in small clusters near demand points. These approaches could substantially improve the existing emergency response time. Distributing ambulances near demand points yielded greater improvements in response time than when the ambulances are stationed near hospitals.     

Organizational differences in managerial compensation and benefits in Chinese firms

More than two decades of economic reforms have brought profound changes in human resource management practices in both the state and non-state sectors in China. This study focuses on the impact of organizational factors on compensation and benefits for Chinese managers in state-owned enterprises (SOEs), publicly listed firms (PLFs), and foreign-invested enterprises (FIEs). The empirical investigation of 465 firms located in three major Chinese cities, Shanghai, Nanjing and Guangzhou, provides evidence that organizational factors, such as ownership, firm size, firm age, location and industrial sector, have significant impacts on the variances in Chinese managers' compensation levels, compensation structures and benefits. The trends in the development of compensation and benefits for Chinese managers are also discussed as the Chinese economy moves closer to a more globalized, highly dynamic economy after China's accession to the World Trade Organization in 2001.

Political corruption shielding and corporate acquisitions

Corruption includes rent‐seeking behavior by public officials (e.g., lavish in‐kind benefits and monetary kickbacks for contracts/permits/regulatory leniency, improper political contributions/support, etc.) that can negatively affect firm valuations, performances, and strategic choices. Shielding strategies are used to diminish rent‐seeking attractiveness of firms. Acquisitions provide a better channel than cash or leverage for assessing the wealth effects of shielding strategies. We find that the mean 3‐day announcement returns for acquirers for a large sample of U.S. domestic acquisitions between 1990 and 2014 is significantly lower for firms headquartered in relatively higher corruption states. Our results survive an array of robustness tests.     

Corporate ownership concentration and audit fees: The case of an emerging economy

The paper investigates the effects of corporate ownership concentration on audit fees in emerging economies, using Bangladesh as a case. Prior studies have indicated that audit fees in Bangladesh are significantly low. Also, the Bangladeshi private sector is dominated by high ownership concentration. Agency theory predicts that in an efficient market, managers in a highly concentrated ownership situation will have sufficient incentives to have more rigorous audits performed. However, managers in emerging economies, where the markets are not as strong, may not have similar incentives. We test whether audit fees in Bangladesh are related to corporate ownership concentration. Our results indicate that audit fees have a significant negative relationship with sponsor and institutional ownership concentrations. This indicates that in Bangladesh, companies actually pay lower audit fees when these are dominated by sponsor and institutional shareholders. For the public shareholders, we find a negative, but statistically insignificant relationship. The results seem to suggest that corporate ownership pattern may be a major factor in explaining the low audit fees in Bangladesh.     

An Investigation into the Potential Adoption of International Financial Reporting Standards in the United States: Implications and Implementation

International Financial Reporting Standards (IFRS) have been adopted by most of the G20 countries. Given the broad worldwide acceptance of IFRS and significance of attaining comparability to facilitate free flow of capital, the US standard setter, the Financial Accounting Standards Board (FASB) made a commitment to jointly work with the International Accounting Standards Board (IASB) to explore the possibilities of convergence of US Generally Accepted Accounting Principles (GAAP) with IFRS. In 2007, the US Securities and Exchange Commission (SEC) eliminated the requirement that foreign companies listed on the US stock exchanges reconcile their IFRS‐based financial statements with the US GAAP. In the same year the US SEC issued a concept release to the public requesting comments on a proposal to allow US issuers to prepare financial statements in accordance with IFRS. Following these initiatives by the FASB and SEC, the aim of the present study is to investigate the implications of a potential full adoption of IFRS by the US. The present study details the challenges and benefits of adoption and outlines the steps required for a successful outcome of this process.
