Globalization and Outward Foreign Direct Investment

While recent research into foreign direct investment (FDI) has focused on examining the importance of institutions, corruption, money laundering, and tax havens, the role of globalization on FDI has not yet been explored. This research investigates the impacts of globalization on outward FDI. We find that both overall globalization and its economic and social dimensions significantly positively influence outward FDI flows. We also demonstrate that beyond the level of globalization, corruption, money laundering, and the status of a country as a tax haven, cross-country similarity also plays an important role. Accordingly, policies specifically designed to increase the transparency of outward FDI flows should be required to address money laundering and the existence of tax havens.     

Export Sophistication: A Dynamic Panel Data Approach

In this article, we analyze export sophistication based on a large panel dataset (2001–2015; 101 countries) and using various estimation algorithms. Using Monte Carlo simulations, we evaluate the bias properties of estimators and show that GMM-type estimators outperform instrumental-variable and fixed-effects estimators. Based on our analysis we document that GDP per capita and the size of the economy exhibit significant and positive effects on export sophistication; weak institutional quality exhibits negative effect. We also show that export sophistication is path-dependent and stable even during a major economic crisis, which is especially important for emerging and developing economies.     

Sovereign Risk Contagion in East Asia: A Mixture of Time-Varying Copulas Approach

This study analyzes sovereign risk contagion between four East Asian economies (China, Hong Kong, Japan, and Korea) and its structural changes through the Global Financial Crisis (GFC) and the European Debt Crisis (EDC) by applying the mixture of time-varying copulas to those economies’ credit default swap (CDS) spreads.

This article first finds a strong contagion from the US and PIIGS economies to the East Asian sovereign CDS markets and intraregional contagion within the East Asian markets. Second, the impact of contagion is different according to whether it is measured by the linear (Gaussian) or the upper tail dependence. Third, Japan plays an important role in increasing the linear dependence whereas China and Korea are crucial in terms of the upper tail dependence. Lastly, the GFC has structurally increased the linear dependence but not the upper tail dependence between the East Asian sovereign CDS markets.     

Overcoming localization of knowledge — the role of professional service firms

The literature on organizational learning asserts that external learning is often limited geographically and technologically. We scrutinize to what extent organizations acquire external knowledge by accessing external knowledge repositories. We argue that professional service firms (PSFs) grant access to nonlocalized knowledge repositories and thereby not only facilitate external learning but also help to overcome localization. Focusing on patent law firms, we test our predictions using a unique dataset of 544,820 pairs of European patent applications. Analyzing patterns of knowledge flows captured in patent citations, we find that accessing a PSF's repository facilitates the acquisition of external knowledge. As the effect is more pronounced for knowledge that is distant to a focal organization, we conclude that having access to a knowledge repository compensates for localization disadvantages.

Institutional duality and political strategies of foreign-invested firms in an emerging economy

This study investigates how the complex institutional environment surrounding foreign-invested firms (FIEs) affects their corporate political strategies (CPS) in China. Analyses of data on 442 FIEs operating in China show that the relative potency of dual institutional pressure from FIEs’ home and host countries shapes their strategic choices. Institutional factors at the country, region, and firm levels not only affect firms’ adoption of multiple firm-based tactics but also shape their collective-oriented associational activities. Moreover, participation in both foreign and domestic business associations enhances an FIE's adoption of firm-based political tactics, but joining domestic business associations has a stronger effect.     

Long-term sustainability of third-party facilitated market linkages: Evidence from the USDA marketing assistance program in the Armenian dairy industry

Public–private partnerships are increasingly seen as an important tool to build agri-food supply chains and develop markets for agri-food products in emerging economies. However, many of these initiatives fail when the public component of the program ends. One exception is the USDA Market Assistance Program (MAP) that facilitated the redevelopment of the Armenian dairy sector after privatization. This paper presents a case study of this initiative and hypothesize that the USDA MAP facilitated farmer investment in private enforcement capital. This investment resulted in sustainable market relationships between farmers and dairy processors even after the USDA MAP expired. We find empirical evidence to support this hypothesis using a panel dataset collected from 172 Armenian dairy farmers in 2004 and 2009.     

Identifying airline cost economies: An econometric analysis of the factors affecting aircraft operating costs

This paper provides the results of an econometric analysis of the influences of airline characteristics on the average operating costs per aircraft movement. The analysis combines a comprehensive selection of airline-output variables, airline-fleet variables, and airline-market variables. The results confirm the existence of economies of density, economies of load factor, economies of aircraft utilisation and economies of aircraft size. The paper does not provide evidence of economies of scale, economies of stage length or economies of fleet commonality. Furthermore, airlines that additionally operate full freighters, airlines that are members of a worldwide alliance and airlines that operate a multi-hub system face higher average operating costs per aircraft movement. Surprisingly, the regression results demonstrate that airlines that use newer aircraft have higher average operating costs per aircraft movement, suggesting that ownership costs (depreciation and leasing costs) of new aircraft outweigh the increasing maintenance costs of old aircraft. Finally, the results show that airlines that have a dominant position at their hubs or bases have higher operating costs per aircraft movement, implying that the absence of serious competitive pressure enables airlines to charge higher ticket prices and, with that, leads to a limited focus on cost savings.     

‘Agents-in-focus’ and ‘Agents-in-context’: The strong structuration analysis of central government accounting practices and reforms in Nepal

Drawing on Stones’ (2005) strong structuration theory, the paper unfolds why and how the key stakeholders of central government accounting in Nepal are involved in the reproduction of routinised accounting practices, resisting the externally-propagated changes. Government accountants (the agents-in-focus) through their capability to control the budget routines have enjoyed a powerful social position in their position–practice relations with the agents-in-context, i.e. professional accountants and international consultants, higher-level officers and administrators, auditors, and politicians. Social position along with historically-imbued dispositions and their conduct and context analysis have enabled government accountants to strategically exercise their agency. Government accountants have articulated duality and a dialectic relation with the agents-in-context, which have resulted in the reproduction of everyday accounting practice and the resistance to the World Bank-led reforms, such as accrual accounting and, more recently, the Cash-Basis IPSAS.     

Do city–county mergers in China promote local economic development?

Municipal mergers have become a worldwide phenomenon in the past few decades, primarily advanced to exploit economies of scale. While most evaluations of municipal mergers have focused on the efficiency of local public goods provision, it is rare in the literature to explore how such mergers promote economic growth in a developing country context. This research investigates the economic consequences of a policy experiment of city–county mergers (che xian she qu) in China during the period 2000–2004. Using comprehensive datasets at city, county and firm levels, we present evidence that the merger significantly increases local economic development, and the magnitude of the effect depends on local endowments related to agglomeration forces. The results are robust to a number of different model specifications. We further verify that improved transport infrastructure and urban agglomeration economies after merger are potential contributors to the positive merger effects.
