W-+ H+- production and CP asymmetry at the LHC

The dominant contributions to W-+ H+- production at the LHC are the tree-level b anti-b annihilation and the gg fusion. We perform for the case of the complex MSSM a complete calculation of the NLO EW corrections to the b anti-b annihilation channel and a consistent combination with other contributions including the standard and SUSY QCD corrections and the gg fusion, with resummation of the leading radiative corrections to the bottom-Higgs couplings and the neutral Higgs-boson propagators. We observe a large CP-violating asymmetry, arising mainly from the gg channel.Comment: 33 pages, 21 figures, a few typos corrected, one reference adde

Bribery offences under Vietnamese criminal law in comparision with Swedish and Australian criminal law

There have been attempts, all over the world, to address bribery with recourse to criminal law. As many other countries, Vietnam has been doing activities that show the determination of combating and controlling corruption, including strengthening penal provisions in terms of bribery. However, the situation of bribery in Vietnam is still alarming. For Vietnamese law enforcement authorities, criminal provisions concerning bribery are neither adequate nor clear. Analysis starts with both theoretical and practical issues relating to such offences. The understanding of bribery offences in the light of criminal law is addressed in the idea that the concept of bribery should be perceived in a modern and broad approach to include bribery in the private sector, bribery of foreign public officials; and the criminalization of different types of bribery is dependent on social attitude towards the phenomenon and the need of protecting values concerning not only government system but also private interests. Relevant international standards are analyzed respectively. The research then examines the existing criminal law of Vietnam regarding bribery offences in comparison with that of Swedish and Australia. Domestic laws on bribery indicate the considerable consistency with relevant criminal law theories. However, bribery provisions in Vietnamese Penal Code exist gaps relating to relevant Convention, including lacks of bribery in the private sector and bribery of foreign public officials. Consequently, recommendations both in building comprehensive elements of crimes and setting proportionate sanctions for crimes are made for the amendments of Vietnamese Penal Code

An empirical analysis of the manufacturing sector in Vietnam during the period 2000-2006 with a particular emphasis on technical efficiency, trade reforms and workplace injuries

This thesis investigates empirically the manufacturing sector in Vietnam during the period 2000-2006. The main objective is to provide a comprehensive analysis on the technical performance, and workplace safety of this sector. The analysis uses the sub-dataset for the manufacturing sector extracted from the annual Vietnam Enterprise Surveys for the period under consideration. Chapter one provides an overview of the economic renovation (commonly called Doi moi). The chapter reviews milestones in the Doi moi process and its consequences in terms of economic structural changes, trade, and investment. Chapter two describes the dataset used in the thesis and the construction of the key variables adopted in the subsequent chapters. Chapter three estimates technical efficiency in the Vietnam’s manufacturing sector. The chapter explores if, among other things, the estimates of technical efficiency obtained using the stochastic frontier approach are sensitive to the different distributional and econometric assumptions. Based on several test results, the chapter concludes that average manufacturing sector operated at 62 percent of its technical efficiency. Chapter four investigates empirically the determinants of technical efficiency in the Vietnam’s manufacturing sector using both mean and quantile regression approaches. Results suggested that types of ownership, feminization, and compliance of firms to labour market regulation are among important determinants of technical efficiency. Notably, there is a positive, albeit modest impact of trade liberalization on technical performance of the manufacturing sector and this impact is most pronounced for the least technically efficient firms. Chapter five focuses attention on workplace injuries in the manufacturing sector. As data on workplace injuries in Vietnam is very limited, a number of experiments was tried to find the most relevant estimation strategy. The chapter finally adopts a probit model and a simple OLS to inform determinants of workplace injuries. Results suggest that types of ownership and firm size are important factors that exert influences on workplace injuries reported. Interestingly, the foreign-invested sector was found to be the worst performer compared to the domestic counterparts in terms of technical efficiency and workplace safety. Drawing from these chapters, some policy conclusions, limitations of the current exercise, and outlines of possible agenda for future research in this area are discussed in the conclusion section

Is Nonfarm Diversification a Way Out of Poverty for Rural Households? Evidence from Vietnam in 1993-2006

school. Using the four high quality household living standards surveys available to date this paper reveals that Vietnam’s rural labour force has been markedly diversifying toward nonfarm activities in the doi moi (renovation) reform period. The employment share of the rural nonfarm sector has increased from 23 percent to 58 percent between the years 1993 and 2006. At the individual level, the results indicate that participation in the rural nonfarm sector is determined by a set of individual-, household-, and community-level characteristics. Gender, ethnicity, and education are reported as main individual-level drivers of nonfarm diversification. Lands as most important physical assets of rural households are found to be negative to nonfarm employment. It is also evident that both physical and institutional infrastructure exert important influences on individual participation in the nonfarm sector. At the household level, a combination of parametric and semi-parametric analysis is adopted to examine whether nonfarm diversification is a poverty exit path for rural households. This paper demonstrates a positive effect of nonfarm diversification on household welfare and this effect is robust to different estimation techniques, measures of nonfarm diversification, and the usage of equivalent scales. However, the poor is reported to benefit less than the non-poor from nonfarm activities. Though promoting a buoyant nonfarm sector is crucial for rural development and poverty reduction, it needs to be associated with enhancing access to nonfarm opportunities for the poor.Rural nonfarm sector, nonfarm diversification, household welfare, Vietnam
