Impact of R&D expenditures,rainfall and temperature variations in agricultural productivity: empirical evidence from Bangladesh

ABSTRACT

This study aims to investigate dynamic relationships between research and development (R&D) expenditure, climate change (measured by annual rainfall and temperature variations), human capital (proxied by literacy) and total factor productivity (TFP) growth in Bangladesh agriculture. Pesaran’s Pooled Mean Group (PMG) estimator is used to a unique panel data of 17 regions of Bangladesh covering a 61-year period (1948–2008). In addition, the panel vector autoregression (PVAR) model is also applied to trace the responsiveness of TFP from a shock to R&D, extension services, and literacy rate. Results reveal that R&D has an insignificant impact on TFP in the short-run, while it has a significant positive impact in the long-run. The contributions of climate variables (i.e., rainfall and temperature variations) are highly significant and negative in the long run. The literacy rate is found to have a significant positive impact on TFP as expected. These results suggest that agricultural R&D investment and human capital could play an important role to ameliorate the adverse effects of climate change in the agricultural sector of Bangladesh.

Environmental impacts of technological change in Bangladesh agriculture: farmers' perceptions, determinants, and effects on resource allocation decisions

This article measures the impact of modern technology adoption in raising farmers' environmental awareness and the impact of farmers' environmental awareness on resource use by utilizing survey data from 21 villages in three agro‐ecological regions of Bangladesh. The econometric analysis is based on the application of the Tobit model explaining farmers' environmental awareness in the first stage and a profit function examining environmental awareness and resource use relationships in the second stage. Results reveal that the “level” and “duration” of involvement with modern technology raises farmers' environmental awareness, and that farmers' environmental awareness reduces resource use including chemicals. Farmers, who are aware of the adverse environmental impacts of modern agricultural technology, use lower amounts of all inputs in order to avoid further environmental damage. Therefore, efforts to raise farmers' environmental awareness are expected to enhance intangible benefits accruing from a relatively less chemical‐intensive environment.     

Technical,Allocative, Cost and Scale Efficiencies in Bangladesh Rice Cultivation: A Non‐parametric Approach

Applying programming techniques to detailed data for 406 rice farms in 21 villages, for 1997, produces inefficiency measures, which differ substantially from the results of simple yield and unit cost measures. For the Boro (dry) season, mean technical efficiency was 69.4 per cent, allocative efficiency was 81.3 per cent, cost efficiency was 56.2 per cent and scale efficiency 94.9 per cent. The Aman (wet) season results are similar, but a few points lower. Allocative inefficiency is due to overuse of labour, suggesting population pressure, and of fertiliser, where recommended rates may warrant revision. Second‐stage regressions show that large families are more inefficient, whereas farmers with better access to input markets, and those who do less off‐farm work, tend to be more efficient. The information on the sources of inter‐farm performance differentials could be used by the extension agents to help inefficient farmers. There is little excuse for such sub‐optimal use of survey data, which are often collected at substantial costs.     

Resource use efficiency under self‐selectivity: the case of Bangladeshi rice producers

The paper jointly evaluates the determinants of switching to modern rice and its productivity while allowing for production inefficiency at the level of individual producers. Model diagnostics reveal that serious selection bias exists, justifying the use of a sample selection framework in stochastic frontier models. Results revealed that modern variety selection decisions are influenced positively by the availability of irrigation and gross return from rice and negatively by a rise in the relative wage of labour. Adoption of modern rice is higher in underdeveloped regions. Seasonality and geography/location does matter in adoption decisions. Stochastic production frontier results reveal that land, labour and irrigation are the significant determinants of modern rice productivity. Decreasing returns to scale prevail in modern rice production. The mean level of technical efficiency (MTE) is estimated at 0.82. Results also demonstrate that the conventional stochastic frontier model significantly overestimates inefficiency by three points (MTE = 0.79). Policy implications include measures to increase access to irrigation, tenurial reform and keeping rice prices high to boost farm returns and offset the impact of a rise in the labour wage which will synergistically increase the adoption of modern rice as well as farm productivity.     

A Hierarchical Model of Perceived Value of Group-Oriented Travel Experiences to Major Events and its Influences on Satisfaction and Future Group-Travel Intentions

This study seeks a deeper understanding of the forms of value that travel consumers derive from a group-travel experience to a major event. We focus on specific group-travel value dimensions of social, hedonic, monetary, functional – major event, functional – event-destination tourism infrastructure, epistemic, and convenience. A sample of 389 consumers is used to substantiate our framework. We also empirically examine this model with satisfaction and future group-travel intentions – with satisfaction found to fully mediate the relationship between the perceived value of the group-travel experience and future group-travel intentions. This framework can serve to advance further theory development in this domain.     

A Review of Institutional Alternatives to Collateralized Lending

Abstract: Rural producers’ access to formal finance has often been limited by their inability to provide collaterals, particularly in the form of registered or certified land titles and tenancy contracts or assets which are auctionable as well as by laws that make foreclosure difficult. This paper reviews some of the alternative institutional arrangements (possibilities) for reducing and overcoming collateral requirements such as third party guarantees, ownership of tradeable assets, credit guarantee schemes, group lending, credit‐savings linkages, incremental and loan repayment‐dependent lending, portfolio diversification and an efficient legal system for contract enforcement. It also specifies the land policy and tenure reforms that are desirable, especially in the direction of formal land titling or legally specified rights to the use and ownership of lands, the consolidation of land holdings and the provision of proper cadastres for land and assuring that titles are secure.     

Luddites, the industrial revolution, and the demographic transition

Technological change was unskilled-labor-biased during the early industrial revolution, but is skill-biased today. This implies a rich set of non-monotonic macroeconomic dynamics which are not embedded in extant unified growth models. We present historical evidence and develop a model which can endogenously account for these facts, where factor bias reflects profit-maximizing decisions by innovators. In a setup with directed technological change, and fixed as well as variable costs of education, initial endowments dictate that the early industrial revolution be unskilled-labor-biased. Increasing basic knowledge then causes a growth takeoff, an income-led demand for fewer but more educated children, and a transition to skill-biased technological change in the long run.     

Regional Developmental Problems of the Rural Settlements in Bosnia and Herzegovina

The paper considers developmental problems of the rural settlements in Bosnia and Herzegovina, which are results of long-term disparity in the regional development in the period 1991-2012. In this paper it is considered the recent migration from rural to urban areas and the depopulation of the rural areas. The result of these trends reflects the development of the new infrastructure and tertiary activities. In these investigations, statistical data processed and geovisualised in GIS were used. The obtained data indicate extremely unequable regional arrangement of the population in the rural areas and socio-economic development.     

Investigation of Directional and Functional Relationships of Australian Dollar Exchange Rate,Steam Coal Export,and Steam Coal Price

The interesting finding in this article is that the Australian coal exporter's loss, which occurs due to a strong Australian dollar, is less than the profit from increasingly higher prices of Australian steam coal. For this reason, Australian steam coal exporters choose to export more when the price is high. The empirical results of this analysis confirm that for each one cent increase in Australian dollar value against the U.S. dollar, the Australian steam coal price increases by 0.8182 U.S. dollars and for each additional one million tons export of Australian steam coal, the Australian steam coal price increases by 1.752 U.S. dollars.
