DEVELOPMENT OF AIR TRANSPORT INDUSTRY IN THE ASIA‐PACIFIC REGION

The volume of air passengers and cargo in the Asia‐Pacific region has grown significantly over the past decade due to the strong impetus of economic growth as well as trade and economic integration at both the regional and global levels. Although public funds have been the main source of financing for airports in most parts of the region, governments have increasingly resorted to privatization or are seriously considering it as a form of private sector participation enabling new airports to be built or existing airports to be upgraded. The present paper provides a brief survey of airport privatization in the Asia‐Pacific region, discusses the relevant issues, and introduces the following five papers published in this special section on the air transport industry in the Asia‐Pacific region.     

PORTFOLIO SELECTION BETWEEN A MATURE MARKET AND SELECTED EMERGING MARKETS INDICES IN THE PRESENCE OF STRUCTURAL BREAKS

The paper examines the influence of the structural breaks on the optimal weights, hedge ratios and hedge effectiveness index (HEI) of risk‐minimizing portfolios composed of S&P500 and selected emerging markets’ indices from East Europe, Asia and South America. We employ a bivariate DCC‐EGARCH models without and with structural breaks and we find better estimation features when structural breaks are included in the model. However, we do not find evidence that insertion of structural breaks increases portfolio hedging performances. The differences that exist between optimal weights, hedge ratios and HEI values are so small that tangible economic benefit for international investors do not exist.     

The Taxation of Financial Capital under Asymmetric Information and the Tax‐competition Paradox

Information sharing between governments is examined in an optimal‐taxation framework. We introduce a taxonomy of alternative systems of international capital‐income taxation and characterize the choice of tax rates and information exchange. The model reproduces the conclusion found in earlier literature that integration of international caopital markets may lead to the under‐provision of publicly provided goods. However, in contrast to previous results in the literature, under‐provision occurs due to inefficiently coordinated expectations. We show that there exists a second equilibrium with an efficient level of public‐good provision as well as complete and voluntary information exchange between national tax authorities.     

Third‐degree price discrimination in the presence of congestion externality

This paper analyzes third‐degree price discrimination of a monopoly airline in the presence of congestion externality when all markets are served. The model features the business‐passenger and leisure‐passenger markets where business passengers exhibit a higher time valuation, and a less price‐elastic demand, than leisure passengers. Our main result is the identification of the time‐valuation effect of price discrimination, which can work in the opposite direction as the well‐known output effect on welfare. This time‐valuation effect clearly explains why discriminating prices can improve welfare even when this is associated with a reduction in aggregate output.     

Sovereign Debt Capacity and the Distribution of Domestic Wealth: A Common Agency Model*

This paper proposes a stylized two‐period, two‐country model illustrating the role of distribution of domestic wealth in determining a country's level of access to international lending. We model sovereign debt redemption policy in a common agency framework. Within this framework, policy is the outcome of the interaction between government and local and foreign interest groups with conflicting preferences on debt repayment. Our main result is that in full lobby competition, when all interests are represented, the only equilibrium solution is repudiation and the consequent inability of government to access international capital markets. Conversely, when the ability to lobby depends on wealth, governments can access international credit up to a given maximum external debt capacity, determined by the skew in the distribution of domestic wealth.     

我国城市间航空客运量影响因素的实证分析

城市间航空客运需求是航空公司航线网络布局时需要参考的重要信息。文章分析了影响城市间航空客运量的因素,建立了描述城市间航空客运量的半对数形式的线性计量经济模型,并使用我国2002年的352个城市对的横截面数据对模型进行了估计。分析结果表明,城市间距离、机场旅客吞吐量、人口密度、邮政电信业务总量、人均拥有公共交通车辆数以及城市性质和GDP相比,与城市对航空客流有着更为密切的相关关系。文中所建立的城市对客运量的回归模型可以作为航空公司进行航线需求分析的基础。     

The Sleeping Giant Awakes: Projecting Global Implications of China's Energy Consumption

China's rapid economic growth has generated a surge in energy demand that is reallocating global fuel balances. We employ a global energy computable general‐equilibrium model to analyze alternative scenarios for economic growth, Chinese currency appreciation, and oil price shocks, with a special focus on China energy markets. Imports from the Middle East, Central Asia, Russia, and Sub‐Saharan Africa are found to comprise a growing share of China's energy. Imports to China grow from 12% of world energy imports in 2010 to 17% by 2050 when over 80% of China's oil demand will be imported.     

WTO Exceptions as Insurance

The paper formalizes the notion that GATT exceptions such as antidumping and escape clause actions can act as insurance for import competing sectors affected by adverse price shocks. The authors use a general‐equilibrium model with several import competing sectors and assume incomplete markets so that agents cannot contract insurance. It is shown that sector‐specific contingent protection measures are superior to uniform contingent tariffs as an insurance mechanism. A tax‐cum‐subsidy policy (i.e., taxing all sectors in order to subsidize the shocked sector) also improves welfare and is superior to contingent protection.     

CROSS‐BORDER INTEGRATION IN NORTHEAST ASIAN AIR TRANSPORT MARKET

This study highlights the recent global trends of the air transport market and develops a simulation model to assess the welfare impacts of tripartite liberalization in the Northeast Asian air transport market. First, in the global air transport market, routes between 1000 and 2000 km are identified as the fastest growing segment. Gravity model analysis reveals that there is potentially significant room for further growth from cross‐border liberalization. Second, in the impact assessment of market liberalization in Northeast Asia, the effect of tripartite market liberalization of triangular routes that connect major cities in each of the three nations, Japan, South Korea and Mainland China, is analyzed. Simulation using a Cournot model with product differentiation shows that overall welfare gains would be achieved from tripartite liberalization. Air carriers' losses are overridden by an increase in consumer surplus. Such an arrangement by the three nations might eventually lead to an integrated environment in which airlines could evolve into a true multi‐hub Northeast Asian air carriers.

TESTING CONVERGENCE OF FIJI'S TOURISM MARKETS

Abstract.   The convergence hypothesis for tourism markets is based on the tenet that when tourism markets are converging the difference between total international visitor arrivals to a country and international visitor arrivals from a particular country will be stationary. We argue that if this is true, then convergence can also be tested through examining whether total visitor arrivals and visitor arrivals from a particular market are cointegrated. We test the convergence hypothesis by examining visitor arrivals to Fiji from eight tourist source markets, using both unit root and cointegration tests. We find strong statistical evidence that Fiji's tourism markets converge.     

Study on the price co-movement among the Asia Pacific,European and Chinese coal markets – based on the empirical analysis of MS-VEC model

In this article, based on weekly data of the three major coal markets (the Asia Pacific, Europe and China) from March 2008 to November 2014, an empirical research on their mutual influence and price co-movement effect among the three major coal markets is conducted by using the Co-integration Theory, Granger Causality Test and markov switching-Vector Error Correction (MS-VEC) model. The conclusions are as follows. (1) There exists a long-term cointegration relationship and bidirectional causality relationship between coal prices at home and abroad, and the influences of foreign coal markets on the domestic coal markets are stronger than the influences of domestic coal markets on foreign coal markets, and thus the interaction between the two markets leads to asymmetric linkage effects. (2) Compared with the VEC model, the MS-VEC model can reflect the nonlinear feature of price co-movement effects. (3) There exists an inherent adjustment mechanism between domestic and foreign coal markets, i.e. the coal prices will be self-revised continuously until a long-term equilibrium state is achieved when a deviation from the equilibrium state occurs. (4) There exists a co-movement effect which varies with the change of regime among the three coal prices, and the self-maintenance is strong and the status transfer phenomenon is clear in different regimes.     

DYNAMICS BETWEEN NORTH AMERICAN AND EUROPEAN AGRICULTURAL FUTURES PRICES DURING TURMOIL AND FINANCIALIZATION

North American and European agricultural futures markets faced significant changes in recent years, i.e., the financialization which originated in the USA, the increase of futures trading in Europe and the recent price turmoils in international commodity markets. We analyse the long‐ and short‐run dynamics between North American and European agricultural futures prices during these institutional changes. The empirical results show that the US markets lead in terms of price transmissions and volatility spillovers. US markets, however, predominantly react to deviations from the long‐run equilibrium which indicates a rising impact of European agricultural markets on a global scale.     

Productivity and Firms’ Sales Destination: Chinese Characteristics

In the trade literature, it is often assumed that there is little or no trade cost within a country's borders, but large trade costs across a country's borders. Thus, productive firms self‐select into exporters and the less productive firms can only serve domestic consumers. This paper presents a similar but different case in China, whose domestic markets are segmented by provincial borders mainly owing to the various (hidden) protective measures favoring local firms. These discriminative measures are de facto trade barriers. It applies the heterogeneous trade theory to examine the effects of firms’ productivity on their sales choices in both the international and domestic markets, in the presence of intra‐national and international trade costs. We find that productive firms not only self‐select into exporters, but also into sales in other provincial markets. This pattern is sensitive to firms’ locations and ownerships. For foreign direct investment (FDI)‐controlled firms, increases in productivity are associated with a higher probability of selling into other provincial markets, rather than into international ones. Productivity increases for firms operating in the inland area exhibit different patterns than those in the Eastern area.     

R&D Spillovers and Growth: Specialization Matters

We explore the relationship between openness and growth by taking a closer look at trade‐related knowledge spillovers at the industry level. First, we estimate the relation between sectoral R&D expenditures, trade‐related spillovers, and growth. Next, we incorporate these R&D linkages in a computable general‐equilibrium model for the world economy. We simulate trade liberalization in the model with R&D spillovers and compare the effects on GDP in different regions with a non‐R&D‐based model simulation. We find that the GDP effects of trade liberalization are magnified considerably by R&D spillovers for some regions—notably Japan and Southeast Asia. In other regions, such as China, the additional GDP effects are modest. These findings can be traced back to changing specialization and import patterns.     

Is Asia Decoupling from the United States (Again)?

The recovery from the recent global financial crisis exhibited a decline in the synchronization of Asian output with the rest of the world. However, a simple model based on output gaps demonstrates that the decline in business cycle synchronization during the recovery from the global financial crisis was exceptionally steep by historical standards. We posit two potential reasons for this exceptionally steep decline. First, financial markets during this recovery improved from particularly distressed conditions relative to previous downturns. Second, monetary policy during the recovery from the crisis was constrained in developed economies by the zero bound, but less so in Asia. To test these potential explanations, we examine the implications of an increase in corporate bond spreads similar to that which took place during the recent European financial crisis in a three‐region open‐economy dynamic stochastic general equilibrium model. Our results confirm that global business cycle synchronization is reduced when zero‐bound constraints across the world differ. However, we find that the impact of reduced financial contagion actually goes modestly against our predictions.     

A Model of Crises in Emerging Markets

This paper presents a perfect foresight model of speculative attacks on emerging markets. Credit constrained governments are assumed to have two objectives: to accumulate liquid assets in order to self-insure against shocks to national consumption and to insure poorly regulated domestic financial markets. This policy regime generates endogenous fiscal deficits defined to include the growth of contingent liabilities. The model sets out a sequence of yield differentials consistent with capital inflows followed by anticipated speculative attacks. The model suggests that a common shock generated capital inflows to emerging markets in Asia and Latin America after 1989.     

Spectrum allocation in Latin America: An economic analysis

As elsewhere, wireless markets play a crucial role in Latin American economic growth. Mobile telephone networks increasingly provide the communications infrastructure that has largely been lacking throughout the region. Yet, governments have generally made only modest allocations of bandwidth available to Latin American wireless operators, either absolutely (in terms of spectrum each country could allocate at modest opportunity cost) or relative to countries in North America, Asia and the European Union. Using an empirical model estimated on mobile phone data for international markets, we show that very large social benefits are available to countries that make more spectrum available for mobile phone markets. We conduct simulations using our calibrated model to provide lower bounds for country-by-country gains from larger allocations. We also discuss the impact of alternative regulatory regimes on the feasibility to achieve those social gains.     

Limited asset market participation and the consumption‐real exchange rate anomaly

Abstract Under efficient consumption risk sharing, as assumed in standard international business cycle models, a country's aggregate consumption rises relative to foreign consumption, when the country's real exchange rate depreciates. Yet empirically, relative consumption and the real exchange rate are essentially uncorrelated. This paper shows that this ‘consumption‐real exchange rate anomaly’ can be explained by a simple model in which a subset of households trade in complete financial markets, while the remaining households lead hand‐to‐mouth (HTM) lives. HTM behaviour also generates greater volatility of the real exchange rate and of net exports, which likewise brings the model closer to the data.
