We examine liquidity commonality in commodity futures markets. Using data from 16 agricultural, energy, industrial metal, precious metal, and livestock commodities, we show there is a strong systematic liquidity factor in commodities. Liquidity commonality was present in 1997–2003 when commodity prices were relatively stable and during the recent boom. There is some support for both “supply-side” and “demand-side” explanations for this commonality. We find no evidence of a consistent link between stock and commodity liquidity in general. Energy commodities appear to provide a better hedge against equity market liquidity risk than the other commodity families. 相似文献

This article investigates the effects of competition on bank risk taking behaviour in four South East Asian countries (Indonesia, Malaysia, Philippines and Vietnam). Our main finding is that competition does not increase bank risk-taking behaviour and the results appear robust to different model specifications, estimation approaches and variable construction. We also find that concentration is inversely related to bank risk whereas regulatory restrictions positively influence bank risk-taking. 相似文献

The event study methodology of Brown and Warner (1985) is adopted and augmented to evaluate the effect of the launch of multilateral trading systems on risk and return in equity markets. The methodology is supplemented with various techniques, such as the nonparametric ranking test and kernel regression, to find out if announcements about the introduction of Chi-X Australia generated abnormal returns (ARs). Asset pricing models are fitted with interaction variables, while GARCH, threshold ARCH (TARCH), exponential GARCH (EGARCH) and power-ARCH (PARCH) are used to determine changes in systematic risk. We find evidence in favour of Fisher’s separation theorem and detect a new market anomaly, which we call the ‘Fisher market anomaly’. Our results show that Chi-X system testings affect ARs. Consistent with the adaptive expectations theory, we confirm that the first announcement about the launch of Chi-X affected systematic risk the most. In addition, we identify industry and firm effects in risk analysis. 相似文献

This paper explores the role of inward foreign direct investment (FDI) as a determinant of domestic firms’ wages, namely wage spillovers. We first construct a theoretical model to demonstrate that the presence of FDI firms affects domestic firms’ expected average wages via productivity spillovers and a cut-off capability. We then estimate FDI-induced wage spillovers by employing IV-GMM estimator with a five-year panel dataset of a growing service industry in Vietnam. Despite FDI firms on average pay 2.25 times that of domestic firms, they put a downward pressure on domestic firms’ wages. A one percent increase in FDI presence causes domestic firms to cut average wages by 2.03 percent. The estimations also find that firm-specific features are attributable to significant differences in their wages as well as FDI-linked wage spillovers. 相似文献

Consumers are increasingly searching for beautiful memories. Memory is not solely the work of the mind retrieving a “true” past. People represent their unique past to (re)construct their identity and seek social links with others who share the remembered events. Through visual analysis of the web posting of war photographs by Vietnam veterans, this paper explores how people consume representations in remembering, reconstructing identities and building a mnemonic community. The analysis suggests that individual remembering is nested within collective remembering. A conceptual framework viewing remembering as mediated action helps to explain how consumers use representations in remembering. This process is carried out not only by individuals but also by cultural institutions. American Vietnam veterans use consumer products including private photographs, movies, books, travel trips and the Internet as tools to assist in the on‐going process of remembering. They add their own voice into the social representation system to create representations that further express who they are and to connect with their community. The constructed memory shapes consumers' present. This in turn modifies their representation of their pasts which become involved in changing the larger social representation system. 相似文献

We use two extremely liquid S&P 500 ETFs to analyze the prevailing trading conditions when mispricing allowing arbitrage opportunities is created. While these ETFs are not perfect substitutes, our correlation and error correction results suggest investors view them as close substitutes. Spreads increase just before arbitrage opportunities, consistent with a decrease in liquidity. Order imbalance increases as markets become more one-sided and spread changes become more volatile which suggests an increase in liquidity risk. The price deviations are followed by a tendency to quickly correct back towards parity. 相似文献

To identify poor households, the government of Vietnam applies a combination of proxy means tests and quick collection of income data. This paper examines how well the government's poverty identification reaches the really poor in Vietnam. It is found that there is a large difference between the poverty rate for provinces and districts reported by the government and the rates estimated using expenditure and income data from independent household surveys. There is also a large difference between the poverty status of households identified by local authorities and the poverty status identified by income or expenditure data. More than 50 per cent of the poor households identified by local authorities are not poor in terms of income or expenditure measures. A better identification approach would be to use only proxy means tests and not income data collected using the simple questionnaire. 相似文献

The purpose of this study is to examine the interaction effects of two commitment foci (parent company and local operation commitment) on a focal work behavior (retention in an international assignment). Accordingly, this study formulated and tested four hypotheses by using hierarchical regression, moderated regression analyses and plots of two-way interactions. The data were gathered from 471 Western expatriates working for the subsidiaries of multinational companies in Vietnam. The results confirmed that all components (affective, normative and continuance) of parent company commitment and local operation commitment positively predicted retention in international assignments; however, the retention was more driven by the parent company commitment. Besides, the relationships between two components (affective and continuance) of local operation commitment and retention were moderated by the corresponding components of parent company commitment. The findings improve the understanding of dual commitment's links to work behaviors in international business contexts. Moreover, as to the practical implication, multinational companies were recommended to be aware of the level of expatriate commitments to two foci in order to reduce the rate of premature return. 相似文献

Which covariates should be controlled in propensity score matching? Evidence from a simulation study
Nguyen Viet Cuong 《Statistica Neerlandica》2013,67(2):169-180
Propensity score matching is a widely‐used method to measure the effect of a treatment in social as well as medicine sciences. An important issue in propensity score matching is how to select conditioning variables in estimation of the propensity scores. It is commonly mentioned that variables which affect both program participation and outcomes are selected. Using Monte Carlo simulation, this paper shows that efficiency in estimation of the Average Treatment Effect on the Treated can be gained if all the available observed variables in the outcome equation are included in the estimation of propensity scores. This result still holds in the presence of non‐sampling errors in the observed control variables. 相似文献
