The community and leasehold forestry regimes (CF and LF regimes) are high priority programmes that are designed by the Nepalese government to conserve forests and reduce poverty through the introduction of formal institutions in terms of legal property rights and governance structures and processes. However, little is known about the mechanisms through which informal and formal institutions influence resource access of the poor under these regimes. By employing a collective case study approach, this research provides some understanding of the mechanisms through which formal and informal institutional factors influence access of the poor to forest resources governed under the CF and LF regimes in Nepal. This study found that informal institutional factors significantly influence the impact of formal institutions irrespective of the regime that was imposed on the Nepalese hill communities. It was revealed that where more than one social group co-exist in a community, discriminatory sociocultural norms (for example patriarchal and caste-based norms), and customary property rights favour one social group over others. As a result, certain social groups have greater access to resources and benefits from the resources than do other social groups. Of particular significance, and not previously reported, the lack of prior experience in collective action of the low castes along with their weak social networks and poor leadership ability is highlighted as being directly linked to their relatively limited access to forest resources. When the Bista system, a specific type of a traditional bridging social network is eroded, the low castes end up with less access due to removal of support from the high castes. This study shows that a more inclusive regime (for example CF regime) is likely to lead to more effective outcomes for the livelihood of the poor as compared to a more exclusive regime (e.g. LF regime). When the powerful are included in the forest user group (FUG), along with the poor, there is less resistance to the shift in property rights and the improved access of the poor to forest benefits that the regimes are intended to achieve. However, it was found that active participation is more determinant of resource access than is a specified set of property rights granted by right of membership in a FUG. Although some FUG governance structures provide a forum where the disadvantaged members of the FUGs have the right to participate in decision making, their participation is constrained by discriminatory sociocultural norms. Further, this study revealed that the decision-making processes dominated by the elites tend to address the needs of the disadvantaged members to only a very limited extent. However, improving capacities has the potential to enhance participation of disadvantaged members in the processes. The research findings suggest that informal institutions must explicitly be considered in the design and implementation of CBNRM regimes in order for them to be successful in improving livelihoods of the poor. The implementing staff need support mechanisms for changing their own attitudes and behaviours to those that are more favourable to the social shift that the regimes are intended to bring about. CBNRM regimes have the potential to improve the livelihoods of the poor, but research must continue on how this can be achieved.

It is a conventional wisdom that since the start of the Chinese economic reform in 1978, the domestic saving structure in China has changed significantly. Previous studies of household saving in China (for example: Qian, 1988, Feltenstein et al, 1990, and Wakabayashi and Mackellar, 1999) have usually relied upon the Keynesian absolute-income hypothesis, Duesenberry's relative-income hypothesis, and Friedman's permanent-income hypothesis. This thesis uses the Modigliani-Brumberg life-cycle hypothesis to examine the determinants of household saving behavior in the Peoples' Republic of China during the period 1978 to 2003. The research uses modern cointegration techniques to examine the impact on saving rates of economic growth, age dependency, wealth, the real interest rate, social security payments and unemployment (as a proxy for income uncertainty). Autoregressive distributed lag models are constructed and tested. The results find that economic growth, the real interest rate and social security payments have the expected effect with significant parameters; age dependency has the expected sign but in one model is not statistically significant; and that unemployment is not significant. The most surprising result is that increases in household wealth are associated with increased saving rates, which may help explain very high economic growth rates in China post 1978.

The three chapters of my dissertation examine immigrant assimilation in the Canadian labour market. Through three levels of analysis, which are distinguished by the sample restrictions that are employed, I investigate immigrant labour force and job dynamics, immigrant propensity for self-employment, and immigrant wage assimilation, respectively. In the first chapter, I exploit recently-introduced immigrant identifiers in the Canadian Labour Force Survey (LFS) and the longitudinal dimension of these data to compare the labor force and job dynamics of Canada's native-born and immigrant populations. I am particularly interested in the role of job, as opposed to worker, heterogeneity in driving immigrant wage disparities and in how the paths into and out of jobs of varying quality compares between immigrants and the native-born. The main finding is that the disparity in immigrant job quality, which does not appear to diminish with years since arrival, reflects a combination of relatively low transitions into high-wage jobs and high transitions out of these jobs. The former result appears about equally due to difficulties obtaining high-wage jobs directly out of unemployment and in using low-wage jobs as stepping-stones. I find little or no evidence, however, that immigrant jobseekers face barriers to low-wage jobs. We interpret these findings as emphasizing the empirical importance of the quintessential immigrant anecdote of a low-quality "survival job" becoming a "dead-end job". The second chapter analyzes immigrant choice of self-employment versus paid employment. Using the Canadian Census public use microdata files from 1981 to 2006, I update the Canadian literature on immigrant self-employment by examining changes in the likelihood of self-employment across arrival cohorts of immigrants and how self-employment rates evolve in the years following migration to Canada. This study finds that new immigrants, who arrived between 1996 and 2005, turned to self-employment at a faster rate than the earlier cohorts and that immigrants become increasingly likely to be self-employed as they spend more time in Canada. More important, I examine immigrant earnings outcomes relative to the native-born, instead of within, sectors and thus explore the extent to which a comparative advantage in self-employment, captured by the difference in potential earnings between the self- and paid-employment sectors, can explain the tremendous shift toward self-employment in the immigrant population. The results show that the earnings advantage between the self- and the paid-employment sectors accounts for the higher likelihood of self-employment for traditional immigrants in the years following migration. However, the potential earnings difference cannot explain the reason that non-traditional immigrants are more likely to be self-employed as they consistently lose an earnings advantage in the self-employment sector relative to the paid-employment sector. My paper suggests that immigrants may face barriers to accessing paid-employment, or immigrants are attracted to self-employment by non-monetary benefits. Lastly, in the third chapter, studies which estimate separate returns to foreign and host-country sources of human capital have burgeoned in the immigration literature in recent years. In estimating separate returns, analysts are typically forced to make strong assumptions about the timing and exogeneity of human capital investments. Using a particularly rich longitudinal Canadian data source, I consider to what extent the findings of the Canadian literature may be driven by biases arising from errors in measuring foreign and host-country sources of human capital and the endogeneity of post-migration schooling and work experience. The main finding is that the results of the current literature by and large do not appear to be driven by the assumptions needed to estimate separate returns using the standard data sources available.

The overriding theme of my dissertation is the use of short-term weather fluctuations to study how people allocate their time across activities. In Chapter 1, a theoretical model is developed to distinguish malfeasant from legitimate forms of employee sickness absenteeism. In this model, individuals' marginal utility of indoor leisure is increasing in their sickness levels, while their marginal utility of outdoor leisure is an increasing function of the interaction of their health and the quality of outdoor weather. In equilibrium, sickness absenteeism occurs at both ends of the sickness distribution -- among the relatively sick and among the most healthy facing the best weather. The positive relation between marginal changes in weather quality and levels of sickness absenteeism in the workplace reflects the substitution of the inframarginal employees who are the least sick away from work activities towards outdoor leisure activities. The model in Chapter 1 suggests an empirical strategy to identify a shirking component in overall reported sickness absenteeism. Not only does this approach avoid attributing entirely legitimate forms of absenteeism to shirking, but unlike previous studies using employee dismissal rates, it is able to distinguish shirking activity whether or not that activity is detected by employers. In order to exploit exogenous weather fluctuations to identify shirking activity, we need a one-dimensional measure of weather “quality”. The primary objective of Chapter 2 is to construct a weather quality index that captures the influence of the weather on workers' preferences for outdoor leisure activity. The weather quality index takes into account the multifaceted nature of weather conditions, and measures how various weather elements -- temperature, humidity, precipitation, wind speed, and cloud cover -- come together to affect the propensity of employees to engage in high-utility outdoor recreational activities. The resulting index provides a ranking of different weather conditions in terms of their outdoor recreational values, which can then be used to capture the incentives of employees to shirk contractual work hours in response to purely exogenous weather changes. Chapter 3 empirically tests the existence of weather-induced substitution between work and outdoor leisure activities and examines how this type of behaviour varies across workers facing different shirking incentives. Linking 12 years of employee data from Canada's monthly Labour Force Survey (LFS), which queries reasons for employees' absences, to weather quality measured using the index constructed in Chapter 2, a clear positive relationship is found between the quality of outside weather conditions and short-term reported sickness absenteeism. Moreover, consistent with a key proposition of the theoretical model in Chapter 1, the empirical relation between weather and sickness absenteeism tends to be larger when existing shirking incentives are low, such as when sick pay is less generous and when probability of getting fired if caught shirking is high. There is, however, little evidence that firms are able to adjust shirking incentives through the payment of efficiency wages. Finally, Chapter 4 examines another type of substitution induced by weather shocks -- the substitution between outdoor and indoor physical activities. The Chapter begins with a theoretical model of the decision to participate in physical activities, which assumes that when adverse weather shocks deter outdoor physical activities, indoor physical activities are the only viable option for individuals to stay physically active. However, because the indoor options are more costly, substituting from outdoor to indoor physical activities is easier for higher-income individuals. This suggests an explanation for the stylized fact that rates of physical activity participation are low among lower socioeconomic groups. Linking time-use data from Canadian General Social Survey with archival weather data, the results of the empirical analysis in this chapter provides evidence of a positive income effect enabling substitution from outdoor to indoor physical activities when outside weather is not conducive for participating in outdoor activities. By exploiting the role that income plays in maintaining physical activity levels when less costly outdoor options are limited, this chapter formally illustrates a credible causal link between people's income levels and their participation in leisure time physical activities and provides direct evidence of this link. The results have important policy implications for promoting physical activities, especially among lower income population.

This thesis investigates the factors that influence the locational choices of foreign firms investing in China and the factors that influence the level of intermediate goods produced by domestic suppliers in China. It finds that some characteristics of the domestic economy are associated with both, and that foreign enterprises? activities are particularly important in determining the output of domestic suppliers. / PhD Doctorate

Existing literature on the airline industry has been largely based on US airline markets due to data availability. The rest of the world, including China?s airline markets, have received relatively little attention. This thesis discusses in some detail the evolution of China's airline industry, current position and the problems faced by the Chinese carriers. In particular, it explores in depth the reasons behind the 2002 airline consolidations, which have brought about many significant changes in China's airline markets. Unlike mergers in developed countries, which might have been assessed and their effects estimated by antitrust authorities before being granted antitrust immunity, the airline mergers that swept China's airline industry in 2002 occurred with no antitrust challenge. This provides researchers with a good opportunity to study market power issues in this market. Using monthly average airfare information for China Eastern Airlines and China Southern Airlines from 2002 to 2004, the actual airfares paid by passengers were found to have significantly fallen in the post-merger period in most Chinese city-pair markets, indicating that competition was still relatively strong and that the major airlines did not seriously abuse any market power gained from the mergers. Based on a reduced form airfare equation in a panel context, the presence of Hainan Airlines appears to have had the competitive effect of suppressing the airfares charged by China Eastern and China Southern. One salient feature of China?s airline industry in the post-merger period is the greatly enhanced multimarket contact of these two major airlines. However, my finding of a negative effect of multimarket contact on airfares in China's airline markets rejects the mutual forbearance hypothesis. In the absence of an effective antitrust law, both fare wars and price collusion have been pervasive in China?s airline markets, causing concern for both airlines and consumers. Both types of conduct tend to be short-lived, but the 'competition then collusion' patterns seem to be repetitive. This observation can be explained in two ways. On the one hand, divergent interests in a particular market at any given time have made it difficult for collusive agreements to be effectively implemented and maintained. On the other hand, the lack of any antitrust intervention has allowed the carriers in China to reach price agreements through overt communication any time they thought it might be commercially helpful. Therefore, both the industrial collusion and price war cycles have not lasted for long periods of time. Using a probit model that estimates the engagement of China Eastern and China Southern in price wars and price collusion, it is found that concentration in both airports and routes did not play any important part in the occurrence of either fare wars or collusion. Multimarket contact had the effect of intensifying and spreading competition in some markets, with no obvious effects of promoting price cooperation. Although the airline mergers overall appear not to have caused seriously anticompetitive consequences, undoubtedly because most carriers were keen to expand in China's fast-growing airline markets, the underlying potential for collusive conduct still demands that a comprehensive antitrust law be adopted to control price-fixing activities, and to stop threats to competition once the airline industry reaches maturity.

Developing timely and reliable house price indices is of interest worldwide, because these measures influence consumer behaviour, inflation targeting, and spot and futures markets. Several techniques for constructing a constant quality price index are available in the literature, but these methods are difficult to apply in localities where market transaction data is limited. Since house price movements are a local phenomena, improving the timeliness of a quality controlled price index at local housing market levels in small countries like New Zealand is a challenge. This thesis comprises three essays that focused on improving the timeliness of reported house price indices at the local market levels. The timeliness issue examined in this thesis has not previously been rigorously investigated and this makes the results of this thesis both important and unique for the benefit of both academic research and practical application. Essay One reviews the sale price appraisal ratio (SPAR) method, which has been applied since the 1960s for producing local house price indices at a semi-annual and quarterly basis in New Zealand. Utilizing a variety of statistical tests and comparing this index with the repeat sales and median price index result in the study highlighting the potential of, as well as the problems associated with, a price index produced by the SPAR method at a monthly level. In the following two essays, monthly price indices are tested using empirical real estate research methods in order to examine their usefulness in exploring the research questions as well as revealing the statistical differences between them. Essay Two studies the relationship between sale price and trading volume, and the ripple effect of local house price comovements. The results show that the trading volume generally leads the sale price in the long-run and the ripple effect is most likely constrained within regions. In Essay Two, the monthly SPAR index produces similar statistical results to those estimated by the repeat sales index for large cities. Essay Three is a study on the market efficiency of housing markets. It is found the local housing market is neither weak-form nor semi-strong form efficient. Local house price movements are strongly correlated and are mean reverting towards their long-run equilibrium. It is further concluded that monthly price indices for small cities are problematic due to the problem of small sample size. Overall, the findings in this thesis show monthly house price indices can be generated by using the SPAR method at local market levels. However, this potential is limited to large cities. Further research can focus on improving the quality of monthly price indices for large cities.
