This study investigates the labour supply behaviour of married Thai women with reference to their own and their spouse's wages. Controlling for spousal education and number of children, the main findings indicate an inverse relationship between married women's labour supply and wages, contrary to the evidence from developed countries. The estimated own wage elasticity ranges from −1.70 to −2.40 and the cross elasticity ranges from −0.16 to −0.17, indicating that the impact of own wage on labour supplied is much larger than spouse's wage. The results from disaggregation classified according to different socioeconomic backgrounds also show negative elasticities between own and spouses' wage across all subgroups, except for those with university degrees and higher income.

This study investigates the boomerang phenomenon among adult children in Thailand. We estimate the effect of having children on co-residence between parents and adult children using Socio-Economic Survey panel data. We find that adult children who have moved out tend to move back in with their parents after having children to save time and money on childcare. The presence of young children increases the likelihood of intergenerational co-residence by over 30%. This study is the first to provide empirical evidence of boomerang kids in an Asian context, which is distinctive compared with Western countries. The relationship between intergenerational co-residence and the maternal labor supply is also examined using the instrumental variable approach based on the cross-sectional Labor Force Survey, which has data covering over 30 years. Our results show that co-residence increases the female labor supply by 21% and also extends women's working hours by 10 hours.

This study examines the degree of educational assortative mating, its evolution, and its relationship with income inequality in Thailand using national labor force survey data from 1985 to 2016. Since the 1990s, Thailand shows a trend of decreasing educational homogamy, but there is evidence of continuing educational hypergamy in Thai households. Using the semiparametric decomposition method of DiNardo, Fortin and Lemieux (1996), the study finds that educational assortative mating has affected changes in household income inequality over time. Furthermore, there exists a negative relationship between income inequality and marital sorting with same education, which contradicts evidence found in developed countries.

Abstract. Along with the technological development, running complicated program on mobile phone become possible. Mobile device allows to easily capture pictures and do corresponding processing. Thus, this paper puts forward a rapid estimation method which is aimed at detecting large-scale logos in the natural environment by using mobile device. For this purpose, feature detectors and objectness measure are applied to rapid estimation method. By using the feature extraction results to evaluate the objectness results, the higher the evaluation is, the more possible the objectness result is a logo region. This paper take 1000 pictures in the natural environment for measurement, the experiment results show the effectiveness of the method.
