Knowledge diffusion and agricultural development

Low agricultural productivity remains the primary source of poverty in the developing regions and yet little is known about the influence on agricultural productivity of domestic and international accumulated R&D knowledge and the channels through which this knowledge is transmitted internationally. Following a large scientific literature, this article argues that R&D and R&D knowledge spillover are ecozone‐specific and, therefore, are transmitted internationally through ecozones, where ecozones are the broadest biogeographic division of the earth's land surface. Using data for a panel of 88 countries, it is shown that international knowledge spillovers are ecozone‐specific and have been an important contributing factor behind the marked widening of the income gap between developed and developing countries since 1983.     

Exploring the widening food gap: an international perspective

Using data for a long panel of 90 developed and developing countries, this article explores the effects of research and development (R&D) and fixed capital stock on agricultural land productivity over the period 1961–2012. Instruments are used for R&D to deal with feedback effects and measurement errors. The results show very high social returns to investment in R&D and to fixed capital stock, suggesting that increasing investment in these factors are promising ways of arresting the increasing food prices due to increasing demand for animal protein, population growth, desertification, salinization, soil erosion, climate change, and decreasing growth in land productivity.     

SLUM DWELLERS' HOUSEHOLD CONSUMPTION PATTERN AND ITS IMPLICATION FOR COST RECOVERY IN SLUM UPGRADING: Evidence from Dhaka, Bangladesh

Strong emphasis has recently been placed on recovery of improvement costs from slum dwellers for sustainable development of low-income urban settlements. Furthermore, socio-economic stratification of slum dwellers is perceived to influence their consumption and investment patterns in the city. Against this background, populations in six slums in Dhaka, stratified into house owners and renters, were studied. Results show that renters have stronger ties with their rural origin where they are likely to return and remit a significant portion of their income, leaving a limited amount for consumption and investment in the city. In contrast, owners have stronger attachment to the city, remit negligible amounts to their village of origin and pay more attention to city consumption and investment. Consequently, any cost recovery approach to slum upgrading implies heavy reliance on owners. But renters can also be expected to share the cost, to some limited extent, in the form of property tax or community services charges. The key point here is the concurrence of renters and owners on the sharing of costs and benefits.     

The effect of fair disclosure regulation on timeliness and informativeness of earnings announcements

This paper examines the effect of Korea’s fair disclosure regulation on the timeliness and informativeness of earnings announcements. The present regulation for Korean listed firms requires that if a company’s sales revenue, operating income (or loss) and net income (or loss) have changed by over 30% compared to the prior year, the firm must disclose this information through a preliminary financial report (PFR) even before the company is audited by external auditors. To analyze the effects of this policy, we first investigate the timeliness of preliminary financial report disclosures. We examine the extent to which Korean listed companies actually comply with the requirement for prompt notification of information concerning material changes in financial performance. Second, we investigate the informativeness of preliminary financial reports by analyzing differential stock market reactions to different timings of preliminary financial report disclosures. Our empirical results reveal that more than half of our sample firms release their preliminary financial reports after external audits are completed, thereby potentially invalidating the effectiveness of the regulation. In addition, we find that preliminary financial reports have information value only if they are disclosed prior to annual audit report dates. This finding supports the notion that timeliness increases the informativeness of preliminary financial report disclosure by curbing insiders’ ability to potentially profit from their information advantage.     

How well do conservation auctions perform in achieving landscape‐level outcomes? A comparison of auction formats and bid selection criteria

This paper studies the performance of auction design features regarding pricing mechanisms and bid selection criteria for securing wildlife zones across different holdings. We compare two pricing mechanisms: a discriminatory‐price auction and a uniform‐price ascending auction, and four bid selection criteria on the basis of: total bid, bid‐per‐value ratio, bid‐per‐area ratio and a mixed criterion where bids are formed on the basis of cost but they are selected based on the bid‐per‐value ratio. We develop a best‐response group‐bidding model for a discriminatory‐price auction where bidders form optimal group bids for individual wildlife zones. In the uniform‐price ascending auction, individual landholders respond to prices, which are successively raised by the auctioneer and whenever all the landholders from a single zone agree to participate (i.e. the first zone is formed), the auction stops. Based on numerical simulations using a bio‐economic model of malleefowl conservation, we observe that the discriminatory‐price auction is more cost‐effective than the uniform‐price ascending auction. However, the budgetary cost‐effectiveness of a discriminatory‐price auction is sensitive to bidder uncertainty about the number of competing bidder groups and the highest cost of establishing a wildlife zone among these groups. In terms of bid selection, the mixed bid selection criterion performs best. We discuss the policy implications of these findings.     

Examining rural income and employment in Bangladesh: A case of structural changes in the rural nonfarm sector in a developing country

This study uncovers some important stylised facts about the structural changes in the rural nonfarm (RNF) economy in Bangladesh for the period 2000–2016 and identifies some broad determinants. Our work uses household-level, secondary sources such as Household Income and Expenditure Survey, Labour Force Survey and Bangladesh Integrated Household Survey. We find that the positive relationship between landownership and rural income has become weaker in recent years, indicating the increasing role of nonland inputs in generating rural income. The share of RNF income in total rural income has increased substantially over the years. The increase in nonfarm income is largely driven by the nonfarm wage income of the richer households, indicating adverse distributional consequences. There are also indications for specialisation in nonfarm activities—the share of income from the ‘mixed’ sources of farm and nonfarm has decreased, and the ‘only nonfarm’ source has increased. Households tend to move away from agriculture and specialise in RNF occupations as the education level increases. Our results offer important insights into rural development strategies and contribute to the broader questions of the development discourse on the structural changes in developing countries.     

Does remittance fuel labour productivity in Bangladesh? The application of an asymmetric non-linear ARDL approach

Bangladesh, a labour-abundant country, is finally learning to reap gains from her labour abundance. The historical under-optimized capital–labour ratio of Bangladesh is slowly moving towards its optimum as the migration of its labour force and consequent inflow of remittance strategically converts its abundant labour into capital. Though the fear that remittance as an alternative source of earning may result in Dutch disease for existing family members; annual data for 1982–2013 and through applying standard testing methodologies, our empirical findings suggest that such a fear is not valid since remittance flow significantly improves domestic labour productivity in Bangladesh in the long run.
