How entrepreneurship ecosystem influences the development of frugal innovation and informal entrepreneurship

This article critically analyses how the entrepreneurial ecosystem and institutional environment influences the development of frugal innovation and informal entrepreneurship. There is a dearth of empirical research on African entrepreneurship ecosystems and complementors that produce innovations in the informal sector. We address this gap, by examining why and how informal businesses operate and evolve. Based on a qualitative approach, interviewing 20 business owners in Nigeria, two focus groups meeting with 5 and 7 business associations leaders, respectively, we examine the role of institutional environments, how entrepreneurs operate and overcome the barriers to entrepreneurship. The results reveal a model of determinants of frugal innovation and informal entrepreneurship ecosystem comprising formal/informal rules, access to market, and family as important elements that act as a means to effective knowledge flows, networking, capital, and resources sharing.     

Drowning--a major but neglected child health problem in rural Bangladesh: implications for low income countries

This study was intended to estimate the magnitude and explore the determinants of childhood drowning in rural Bangladesh. A cross-sectional survey as well as a population-based case - control study was conducted. By multistage cluster sampling 51 147 children aged 1 - 4 years were identified from 108 827 rural households. All drownings in children aged 1 - 4 years in the preceding 5 years were identified and recruited as cases and two living children of the same age group were selected from the same localities as controls. Socio-economic, demographic, environmental and other related information was collected from mothers of both cases and controls by face-to-face interview with the help of structured questionnaires. The incidence of drowning among children aged 1 - 4 years old was 156.4 per 100 000 children-year. The highest rate (328.1 per 100 000; 95% CI 254.8 - 421.7) was observed in 1 year old male children. The proportional mortality due to drowning in the children was 27.9%. Mothers' age and literacy and family income were identified as risk factors. Drowning is one of the major causes of 1 - 4 years childhood mortality in Bangladesh. One-year-old male children from poor families were at great risk of drowning in rural Bangladesh.     

The Output Effects of Money Growth Uncertainty: Evidence from a Multivariate GARCH-in-Mean VAR

In this paper we extend the work in Serletis and Shahmoradi (Macroecon Dyn 10:652–666, 2006) by investigating the effects of money growth uncertainty on real economic activity, in the context of a multivariate framework in which a structural vector autoregression is modified to accommodate multivariate GARCH-in-Mean errors, as in Elder (J Money, Credit Bank 36:912–928, 2004). The model uses a recursive identification scheme, takes into account the possible interaction between conditional means and variances, isolates the effects of money growth volatility on output growth, and is able to explicitly model heteroskedasticity. We use quarterly data for the United States over the period from 1959:1 to 2005:4, provide a comparison among simple-sum, Divisia, and currency equivalent monetary aggregation procedures at each of the four levels of monetary aggregation—M1, M2, M3, and MZM—and find evidence that money growth volatility has significant negative effects on output growth. Issues of structural stability are addressed and sub-sample analysis is performed. Moreover, the robustness of the results to alternative identification schemes, alternative measures of the level of economic activity, and to the use of monthly observations is also investigated.     

Deflationary policy under digital and fiat currency competition

I examine the implications of digital and fiat currency competition on optimal monetary policy according to the Friedman rule (a standard deflationary policy) in a Fernández-Villaverde and Sanches (2016) framework, with no search friction. Consistent with the existing literature, first, I find that monetary equilibrium under a purely private arrangement of digital currencies will not deliver a socially efficient allocation. Second, I place restrictions on the available supply of digital currencies and find that a socially efficient allocation is possible only if the upper bound on digital currency circulation is equal to the rate of time-preference, albeit some degree of government intervention is required to curb the profit-maximizing incentive of the miners. Third, I find that optimal monetary policy at the Friedman rule will be socially inefficient when digital currencies compete with government-issued fiat money. Finally, I show that the Friedman rule is a socially desirable policy only in a purely fiat monetary regime.     

Accounting Reform in Australia: Contrasting Cases of Agenda Building

On 4 March 1997, the Department of Treasury of the Australian Government announced sweeping measures to reform standard setting arrangements in Australia ( CLERP Paper No.1 , Commonwealth of Australia, 1997 ). The Government's agenda is profoundly reformist as it recommended the wholesale adoption of International Accounting Standards by Australian reporting entities, as well as advocating the introduction of market (selling) price accounting both nationally and internationally. While the notion of market value accounting is not new, this recommendation appears to be a historical first from a government, regulatory or standard setting body. Against this background, our study draws on a framework of 'political agenda building' proposed by Cobb and Elder (1972 ) and Cobb et al . (1976 ), in order to compare and contrast the competing standard setting reform agendas adopted by the Australian accounting profession and the Government. Using the Cobb and Elder framework, we discuss potential reasons why the CLERP agenda has supplanted that of the Australian accounting profession as well as some implications of these developments for the future of standards harmonization.     

Bidding in an Electricity Pay-as-Bid Auction

One of the main elements of the recent reform of electricity trading in the United Kingdom is the change from a uniform price auction in the wholesale market to discriminatory pricing. We analyze this change under two polar market structures (perfectly competitive and monopolistic supply), with demand uncertainty. We find that under perfect competition there is a trade-off between efficiency and consumer surplus between the two auction rules. We also establish that a move from uniform to discriminatory pricing under monopoly conditions has a negative impact on profits and output (weakly), a positive impact on consumer surplus, and ambiguous implications for welfare and average prices.
