A stated preference study for a car ownership model in the context of developing countries

A stated preference ( SP) experiment of car ownership was conducted in Mumbai Metropolitan Region ( MMR) of Maharashtra in India. A full factorial experiment was designed to considering various attributes such as travel time, travel cost, projected household income, car loan payment and servicing cost. Data on 357 individuals were collected which resulted in 3213 observations for the calibration of the work trip and recreational trip car ownership models. The car ownership alternatives considered 0, 1 and 2 cars. A multinomial logit framework was used to develop the car ownership model taking the household as a decision unit. The specification and results of the SP car ownership model are discussed. The observed and predicted values matched reasonably when the validity of the SP car ownership model was tested against revealed preference ( RP) data. The car ownership models developed in this study exhibit a satisfactory goodness of fit. It is concluded that the SP modelling approach can be successfully used for modelling car ownership decisions of households in developing countries

Not AvailableA field study was conducted during Rabi season in 2014-15 in the Krishi Vignana Kendra Hirehally, Tumkur District to study the effect of mulches. The experiment was conducted in 4 replications of black polythene mulched and unmulched treatment in green chilli, hybrid MHCP 317-Sierra, variety of Mahyco company. Primary and secondary branches were maximum in black polythene mulched (14 & 23), and least in unmulched (10 & 17) plots. The significant increase of 38% green chilli yield in mulched, compared to unmulched plots, was maximum (20.20 tonne per ha and 12.50 tonne per ha respectively). Mulched treatment reduces labour cost up to 39% compared to unmulched, which is highest among variable costs. The use of black polythene mulch in sweet pepper brought the benefit cost ratio from 2.61 to 2.81.Not Availabl
