Migration and Farm Efficiency: Evidence from Northern Thailand AgEcon
Nonthakot, Phanin; Villano, Renato A..
This paper investigates the relationship between labour migration and agricultural productivity in the Northern Province of Thailand. Drawing on maize production data from a household survey, we estimate a stochastic production function to evaluate the effects of migration, remittances and salient characteristics of migrants on the mean maize output and levels of technical efficiency. Evidence shows that remittances and number of migrant workers facilitate maize production. It was also found that remittances, duration of migration, gender and education of migrants enhance the productive capacity of maize farmers.

Migration, Household Composition, and Child Welfare in Rural Northeast Thailand AgEcon
Cameron, Michael P.; Lim, Steven.
In many developing countries the composition of rural households is influenced by the migration of adult household members to urban locations in search of employment. Children may be left in the care of their mother alone, or in the care of grandparents when both parents have migrated. Using representative data from a household survey conducted in rural Northeast Thailand in 2003, this paper investigates whether household composition has any effect on the welfare of children, as measured by anthropometric measurements including height-for-age, weight-for-age, and weight-for-height. Our findings suggest that household types other than nuclear families result in some significantly worse child nutritional outcomes. The implication is that governments should...

Modelling Water Use in Thailand AgEcon
Piyanuch, Wuttisorn; MacAulay, T. Gordon; Batterham, Robert L..
In this paper a model is proposed for analysing alternative policies that might be used in allocating water in Thailand. The model used is an integration of farm linear programming models with a spatial equilibrium model, using the so-called price-linked farm and spatial model (Batterham and MacAulay, 1994). A method of linking spatial equilibrium models and linear programming representations of farm models via the demand side as opposed to the supply side is outlined in this paper. A case study is made of the Chao Phraya Delta, an area that is progressively challenged by competing claims for water use and which needs to better allocate water resources.

Modern food retailers and traditional markets in developing countries: Comparing quality, prices, and competition strategies in Thailand AgEcon
Schipmann, Christin; Qaim, Matin.
Supermarkets and hypermarkets are expanding rapidly in many developing countries. While consequences for farmers and consumers were analyzed recently, little is known about the implications for traditional retail formats such as wet markets. Using data from a market survey in Thailand and hedonic regression models, we analyze quality and prices for fresh vegetables from different retail outlets. Compared to wet markets, modern retailers sell higher quality at higher prices, indicating that they are primarily targeting better-off consumers. Hence, they are not directly competing for the same market segments. Yet there are signs that modern and traditional markets will gradually converge.

Modern Supply Chains and Product Innovation: How Can Smallholder Farmers Benefit? AgEcon
Schipmann, Christin; Qaim, Matin.
There is an emerging body of literature analysing how smallholder farmers in developing countries can benefit from modern supply chains. However, most of the available studies concentrate on export markets and fail to capture spillover effects that modern supply chains may have on local markets. Here, we analyse the case of sweet pepper in Thailand, which was initially introduced as a product innovation in modern supply chains, but which is now widely traded also in more traditional markets. Using survey data from smallholder farmers and econometric techniques, we show that sweet pepper cultivation contributes significantly to higher household incomes. Strikingly, at this stage, participation in modern supply chains does not lead to higher incomes than...

Molecular characterization of Plasmodium juxtanucleare in Burmese red junglefowls (Gallus gallus spadiceus) in Thailand OAK
Tattiyapong, M.; Deemagarn, T.; Mohkeaw, K.; Ngamjiteu, S.; Jiratanh, M..
Plasmodium gallinaceum and Plasmodium juxtanucleare are the most common species of Plasmodium causing avian malaria in domestic and wild chickens. In Thailand, P. gallinaceum infection in poultry has been reported since 1996, but P. juxtanucleare infection has never been reported. The objective of this study was to identify and characterize the Plasmodium species infecting Burmese red junglefowls (Gallus gallus spadiceus) in Thailand using molecular techniques. Seventeen Burmese red junglefowls from a farm in western Thailand were suspected of being infected with blood parasite. Blood samples of all seventeen Burmese red junglefowls were collected and examined. Microscopic examination revealed the presence of Plasmodium trophozoites in 5 out of 17 samples....

New Product Development in Thai Agro-Industry: Explaining the Rates of Innovation and Success in Innovation AgEcon
Dhamvithee, Pisit; Shankar, Bhavani; Jangchud, Anuvat; Wuttijumnong, Phaisarn.
The Thai food industry is amongst the most dynamic and diverse in the world. Continual innovation in the form of new product development is critical to this industry, and yet new products are more likely to fail than succeed. In this paper,we investigate factors explaining both the rate of new product development as well as the rate of success in products newly introduced into the market, using data from a survey of firms. The methodology involves a Poisson regression to investigate the determinants of innovation and a Least Squares regression to explain success rates in innovation.

ON TESTS FOR LONG MEMORY PROCESS BEHAVIOR OF INTERNATIONAL TOURISM MARKET: THAILAND AND INDIA AgEcon
Sriboonchitta, Songsak; Chaitip, Prasert; Balogh, Peter; Kovacs, Sandor; Chaiboonsri, Chukiat.
In our research we examine the behaviour of both Thailand’s and India’s international tourism market by using long-memory analysis. The international tourism market of Thailand combined with seven groups such as East Asia, Europe, The Americas, South Asia, Oceania, Middle East and Africa. Similarly, the international tourism market of India combined with nine countries: USA, UK, Canada, Germany, France, Japan, Malaysia, Australia and Sri Lanka. Moreover, three statistical tests for long-memory process such as R/S test, Modified R/S test and GPH-test are employed to study these markets. The empirical findings in general provide more support for long memory process in international tourism market of Thailand and evidence for short-term dependence in...

PARTICIPATION OF LOCAL PEOPLE IN WATER MANAGEMENT: EVIDENCE FROM THE MAE SA WATERSHED, NORTHERN THAILAND AgEcon
Heyd, Helene; Neef, Andreas.
In the early 1990s, Thailand launched an ambitious program of decentralized governance, conferring greater responsibilities upon sub-district administrations and providing fiscal opportunities for local development planning. This process was reinforced by Thailand’s new Constitution of 1997, which explicitly assures individuals, communities and local authorities the right to participate in the management of natural resources. Drawing on a study of water management in the Mae Sa watershed, northern Thailand, this study analyzes to what extent the constitutional right for participation has been put into practice. To this end, a stakeholder analysis was conducted in the watershed, with a focus on the local people’s interests and strategies in water management...

Postharvest R & D concerning tropical fruits AgEcon
Chudleigh, Peter D..
An economic evaluation of two Australian Centre for International Agricultural Research (ACIAR) projects in the area of postharvest technology for tropical fruits was undertaken. This evaluation considered a 30 year time period from the first year of investment and assumed a discount rate of 5 per cent. The estimate of the net present value of the research and development investment was $93 million expressed in 1996/97 terms. The benefit–cost ratio was 38:1 and the internal rate of return estimated at 64 per cent. If benefits realised by 1996/97 were considered, the net present value was $30 million, the benefit–cost ratio was 13:1, and the internal rate of return was 63 per cent. Benefits accrued to both Thailand and Australia, with the proportion of...

Potential income gains for rural households in North Eastern Thailand through trade with organic products AgEcon
Morawetz, Ulrich B.; Wongprawmas, Rungsaran; Haas, Rainer.
The study groups households in North Eastern Thailand according their income and grade of specialisation in crop production to derive representative household types. For these household types a linear optimization model is run to calculate net incomes under four scenarios. These are certified organic farming, organic farming in the initial and transitional phase and a self-sufficient farming. Simulations for the different management scenarios show that per ha cash profits are about double under certification while they can only be increased by 30 percent under self-sufficient farming, even under favourable assumptions. But transition costs to organic farming are high due to reduced yields at the beginning. According to the figures and model used, only...

Pumidonming, Wilawan; Salman, Doaa; Gronsang, Dulyatad; Abdelbaset, E. Abdelbaset; Sangkaeo, Khamphon; Kawazu, Shin-ichiro; Igarashi, Makoto.
Gastrointestinal zoonotic helminths of dogs and cats have a public health concern worldwide. We investigated the prevalence of gastrointestinal helminths of zoonotic significance in dogs and cats in lower Northern Thailand and utilized molecular tools for species identification of hookworms and Opisthorchis viverrini. Fecal samples of 197 dogs and 180 cats were collected. Overall prevalence of infection using microscopy was 40.1% in dogs and 33.9% in cats. Helminth infection found in both dogs and cats included hookworms, Spirometra spp., Taenia spp., Toxocara spp., 0. viverrini, Strongyloides spp. and Trichuris spp. Hookworms were the most common helminth in dogs, while Spirometra spp. were the most prevalent in cats. Among hookworm infection in dogs and...
