Risky arbitrage,asset prices,and externalities

We introduce a no-risky-arbitrage price condition (NRAP) for asset market models allowing both unbounded short sales and externalities such as trading volume. We then demonstrate that NRAP is sufficient for the existence of competitive equilibrium in the presence of externalities. Moreover, we show that if all risky arbitrages are utility increasing, then NRAP characterizes competitive equilibrium in the presence of externalities. We are indebted to an anonymous referee for helpful comments on an earlier version of this paper. Page and Wooders are especially grateful to CERMSEM and EUREQua for their support and hospitality which made possible our collaboration.     

Volatility linkages in the spot and futures market in Australia: a copula approach

To better characterize the dependence structure of the joint returns distribution, we propose to blend copula functions with Asymmetric GARCH (AGARCH) models, which are allowed for generalized error distribution. We model the copula’s marginals by the AGARCH processes that can differentiate between the impacts of positive and negative shocks on the returns volatility while taking the large kurtosis of the returns into account. An application of the procedure is elaborated on the All Ordinaries Index and its corresponding Share Price Index on future contracts in Australia. The findings reveal that the two spot and future markets show a strong right tail dependence but no left tail dependence. This provides a very useful knowledge for the risk management and hedging in futures markets.     

CEO Optimism and the Credibility of Open-Market Stock Repurchase Announcements

Given their low-cost and low level of commitment, open-market stock repurchase announcements are often viewed by the market with a degree of skepticism, leading to a weak initial market reaction followed by positive stock price drifts. The authors argue that the repurchase announcements made by optimistic CEOs should be more credible than those made by nonoptimistic CEOs. Our results show that optimistic CEOs are more likely to actually buy back their shares after the announcements and the abnormal returns following repurchase announcements are larger for optimistic CEOs. This evidence suggests that CEO optimism is an important factor that the market seems to overlook while evaluating the credibility of open-market repurchase announcements. Our main contribution is to link one of the most important managerial traits, optimism, to the open-market repurchases.     

Acquisition of organizational capabilities and competitive advantage of IJVs in transition economies: The case of Vietnam

Using Vietnam as the context, the study empirically examines how the competitive advantage of international joint ventures (IJVs) in transition economies is affected by the acquisition of resources from foreign partners and of local market-based resources. Our study contributes to the nascent literature on IJVs in transition economies by producing several novel and interesting findings. First, it demonstrates the need to modify certain arguments of the resource-based view (RBV) when applied to IJVs in transition economies. This paper shows that the peculiar market characteristics of transition economies serve as an imitation barrier turning even property-based resources into sources of sustainable competitive advantage. Second, the positive impact of knowledge-based resources on the IJV’s competitiveness seems to be significantly enhanced as the ownership by the foreign parent increases. Lastly, competitive advantage of IJVs appears to be strengthened when the transfer of property-based resources is complemented by that of knowledge-based resources, and when the transfer of internal, firm-specific resources is complemented by that of external, market-based ones. We believe that these findings make significant, incremental theoretical and empirical contributions to both the RBV and IJV literatures.

The nexus between firm-supply-chain relationships and the potential for tourism development: A case study approach

This exploratory study examines the importance of firm-supply chain relationships for tourism development. Based upon prior observations, two firms seeking to boost their tourism offerings and operating in a popular Vietnamese tourist destination were selected. Semi-structured face-to-face and online interviews were conducted and complemented by on-site visits, and firm information. Various salient dimensions emerged from the data analysis. The ‘performance catalyst’ and ‘detectable value adding’ dimensions underscore the supply chain's benefits, while the ‘discerning relations’ dimension highlights deeper relationships through mutual support, building trust, or demonstrating care. Conceptually, the study proposes a framework with associated theoretical and practical implications.     

Similarity in trade structure: Evidence from ASEAN + 3

The present paper aims to explore the competition in exports among ASEAN + 3 members by applying the export similarity index for the disaggregation export data from 1990 to 2014. We also discuss the changes of comparative advantage of ASEAN + 3's exports through the revealed comparative advantage index and its relation with similarity index. First, the results support the idea that export similarity varies among ASEAN + 3 member states over the period 1990–2014. Second, we find evidence of several export communities. In particular, five countries, notably China, Japan, Malaysia, Singapore and South Korea, with the highest similarity index form an export community mainly in the electronic microcircuits and parts of office machines. Third, the revealed comparative advantage seems to be the key factor defining the similarity level of exports. Finally, the revealed comparative advantage analysis partly allows us to verify the Ricardo's theory and New Trade theory in the context of ASEAN + 3 trade integration.     

Determinants of Remittances: Recent Evidence Using Data on Internal Migrants in Vietnam*

The present paper examines the determinants of remittance behavior for Vietnam using data from the 2004 Vietnam Migration Survey on internal migrants. It considers how, among other things, the vulnerability of a migrant's life at the destination, their link to relatives back home, and the time spent at the destination affect remittances. The paper finds that migrants act as risk‐averse economic agents and send remittances back to the household of origin as part of an insurance exercise in the face of economic uncertainty. Remittances are also found to be driven by a migrant's labor market earnings level. The paper highlights the important role of remittances in providing an effective means of risk‐coping and mutual support within the family.
