East-West Airlines' Sydney-Melbourne Service: Market Expansion or Demand Diversion?

Data on 1278 flights on the East-West Airlines Sydney-Albury-Melbourne services, beginning when the Sydney-Melbourne excursion fare was first offered, are used to estimate three demand curves for the jointly provided services. The elasticities of demand for the Sydney-Melbourne service suggest it expanded the market as much as it attracted passengers from the trunk carriers. The econometric problem of joint estimation with censored dependent variables should be of general interest.     

Code Sharing and Merger: Continental,Delta and Northwest

When Delta joined the code share between Continental and Northwest in 2003, these three legacy carriers formed the only three-way U.S. domestic code sharing partnership. In 2008, Delta and Northwest announced their intention to merge. The merger was granted by the Department of Justice six months later. This paper analyzes the effects of the three-way code share and the effects of the merger between these two previous code sharing partners. I find both competitive effects and anti-competitive effects of code sharing, i.e., mean market price decrease in non-hub markets and price increase in hub-to-hub markets. Meanwhile, passenger volume increases significantly. Moreover, rivals’ responses are to move price in the same direction as code sharing partners. I find an increase in Herfindahl-Hirschman Index (HHI) and a reduction in traffic after the merger. Specifically, HHI increases for over 1,000 points in markets where merging airlines were either duopolistic or with a third carrier. Pre-merger code sharing markets experience an increase in HHI due to the disappearance of the code sharing contract. Low cost carrier entry mitigates merger effects.     

EVALUATION OF ASIAN AIRPORTS AS GATEWAYS: APPLICATION OF NETWORK EQUILIBRIUM MODEL

This research applies the bi‐level market model to the Asia‐based international air transport markets. The model is a two‐stage game in which airlines act as leaders and passengers act as followers. Airlines are assumed to control flight frequencies, and passengers are assumed to choose their optimal route. At the equilibrium point, we have subgame perfect equilibrium. We apply this model to 2003 Asia‐based international air transport markets and conduct some scenario studies. We find that discounting landing charges at Narita Airport increases the passenger flow but diminishes the gateway function for trans‐Pacific transport.     

STOCK‐BOND CO‐MOVEMENTS AND FLIGHT‐TO‐QUALITY IN G7 COUNTRIES: A TIME‐FREQUENCY ANALYSIS

This paper examines co‐movement between stock returns and changes in 10‐year government bond yields as well as flight‐to‐quality behaviour in G7 countries. We conduct the wavelet squared coherence analysis to explore the dynamics in both time and frequency domain. Our results provide evidence of positive co‐movements, which vary over time and across investment horizon. The higher co‐movement is found to be more concentrated in the lower frequency bands. We further analyse the dynamic nature of the scale‐dependent wavelet correlations and find that the correlations are highly volatile and significantly increase across different time scales during the episodes of equity market turbulence. The increase in correlations reflects flights from stocks to safer bond investments as a result of dramatic changes in investor sentiment and risk aversion at times of market stress.     

Wages,Profits, and Rent‐Sharing in an Open Economy

This paper examines the link between international trade and labor market bargaining power. It reviews simple theories of rent‐sharing in closed and open economies. Earlier studies on the issue of rent‐sharing implicitly assume a closed economy. This assumption may provide some misleading results, especially for studying current developments in the US labor market. Empirical results suggest that the apparent decline in labor’s bargaining power in US manufacturing may be attributable to growing international integration.     

Do international flights promote FDI? The role of face‐to‐face communication

International passenger flights facilitate business travel for in‐person meetings abroad. However, the significance of face‐to‐face communication (FFC) is not clear. To identify the FFC channel, this paper examines whether flights promote FDI more strongly for multinational firms that face relatively intensive FFC in foreign production. Expatriate employees are used as a proxy for the FFC intensity. Using firm‐level data on Japanese multinational firms for the period 1989 to 2006, I show that more frequent flights increase new FDI entry, with the larger positive effects for multinationals in high FFC sectors. The results support the FFC channel to connect flights and FDI.     

The Impact of a Marginal Cost Increase on Price and Quality: Theory and Evidence from Airline Market Strikes

This paper examines the impact of a marginal cost increase for one firm on price and quality in a duopoly market. The results are derived theoretically and then tested empirically. The marginal cost increase is interpreted as an increase in the wage one firm pays its workers. The predictions are tested with two United States airline strikes during the 1990's. Quality is proxied in three ways: (1) the number of flights per day, (2) the percentage of flights cancelled, and (3) the percentage of flights arriving late. The results show that the strike coefficients for the effects on quality are most consistent with theoretical predictions when quality is measured as the number of flights per day. These results are encouraging because of the three measures of quality, it seems that number of flights per day is the measure of quality that is most controllable by the .rm. The strike coefficients for the direct effect on price are most consistent with theoretical predictions when quality rankings are determined by the percentage of flights cancelled. The strike coefficients for the total effect on price are most consistent with theoretical predictions when quality rankings are determined by the percentage of flights arriving late.     

Public Employment and Regional Risk Sharing*

We provide an empirical analysis of regional risk sharing in Norway over the period 1977–90. The approach of Asdrubali, Sørensen and Yosha (1996) is extended to take public employment into account as a possible shock absorber. The other channels of risk sharing are capital markets and commuting, taxes and transfers, and credit markets. The estimated degree of regional consumption insurance is very high. We cannot reject the hypothesis that there is full interregional risk sharing in the short term. Public employment absorbs up to 25 percent of private sector output shocks in our analyses. Generally, central government insurance against regional shocks is relatively more important, the more permanent the shocks are, and vice versa for market‐based risk‐sharing channels.     

Optimal Privatization Design and Financial Markets

This paper provides a simple general equilibrium analysis of privatization, exploring its real effects. They derive from the expansion of risk‐sharing opportunities (within an incomplete markets setting) that are created by the addition of a market in the public project property rights. The principal conclusion is that an optimal combination of voucher and share issue privatization can implement the first‐best.     

WATER QUALITY TRADING IN THE PRESENCE OF ABATEMENT‐COST SHARING

This paper examines how water quality trading interacts with nonpoint‐source abatement‐cost sharing (e.g., as currently practiced by the National Resource Conservation Service through its Environmental Quality Incentives Program [EQIP]) to promote the participation of nonpoint sources in a water quality market, participation that has thus far been noticeably lacking nationwide. As such, an idealized version of water quality trading is envisioned, where water quality trading and nonpoint cost sharing are treated as complementary policy instruments rather than substitutes. Toward this end, the subgame‐perfect equilibrium concept is used to model a “multilateral contracting” relationship between the regulatory authority and nonpoint sources when the regulator has incomplete information about the nonpoint sources' production costs. We characterize ex ante (or second‐best) nonpoint abatement levels when the regulator chooses cost‐share rates in concert with a water quality market. Numerical analysis indicates that current EQIP cost‐share rates would likely be lower and more flexibly determined in the presence of water quality trading. (JEL Q53)     

Is virtual codesharing a market segmenting mechanism employed by airlines?

It has been suggested that virtual codesharing is a mechanism used by airlines to segment passengers based on their price sensitivity. The objective of this paper is to test whether passengers' choice behavior is consistent with market segmentation being the primary motive for virtual codesharing. The findings fail to support the market segmentation motive.     

Welfare Effects of Transparency in Foreign Exchange Markets: the Role of Hedging Opportunities

The paper studies the impact of more transparency on the risk‐sharing opportunities in the foreign exchange market and the associated implications on ex ante welfare. Transparency is measured in this model by the informational content of publicly observable signals about exchange rate developments. The authors find that in this model more transparency improves welfare in economies that are poorly endowed with capital and/or where investors are not very risk‐averse, while welfare is reduced in economies with large capital endowments and/or where investors are highly risk‐averse.     

Marriage, Divorce and Reciprocity-based Cooperation

This paper considers partnership formation, partnership dissolution and reciprocity‐based cooperation by couples in the form of voluntary transfers to smooth consumption. While risk sharing is one benefit of having a partner, it is also limited by the (endogenous) risk of separation. The equilibrium formation and dissolution of partnerships are determined simultaneously with cooperative behavior. Publicly provided earnings insurance is shown to increase the “turnover” rate in the marriage market as well as to reduce the steady‐state marriage rate and the implicit financial cooperation between partners.     

Should Smaller Countries Be More Protectionist? The Diversification Motive for Tariffs

This paper examines the diversification motive for tariffs under trade‐related uncertainty when there is incomplete international and domestic risk sharing. In the context of a two‐country Ricardian continuum‐of‐sectors model with shocks to foreign technologies or preferences, tariffs allow a country to mitigate external risk by diversifying across sectors. Given sufficiently high risk and risk aversion, the optimality of tariffs depends primarily on a country's ability to diversify, rather than its market power, such that small countries gain most.     

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。     

Information sharing and lending market competition with switching costs and poaching

We analyze information sharing with repeated banking competition. In the presence of switching costs we find that information sharing renders poaching more profitable in future rounds of competition, since the poaching activities can be targeted towards (more) creditworthy borrowers. We find that information sharing reduces relationship benefits, and, therefore relaxes competition for initial market shares. Information sharing introduces a welfare tradeoff by promoting equilibrium profits at the expense of talented entrepreneurs whenever market power persists in credit market, whereas it is a matter of indifference without market power. Thus information sharing may induce exclusion of creditworthy borrowers from credit markets.     

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.     

金融发展与中国跨省消费风险分担

本文利用中国1978—2008年间的省级数据,考察金融发展对消费风险分担程度的影响,结果发现风险分担程度随时间显著变化。在1978-1992年时间段上,金融深化提高了消费的风险分担程度,而信贷市场发展对消费的风险分担程度的影响并不明显。在1993-2002年时间段上,信贷市场发展提高了消费的风险分担程度,而金融深化降低了消费的风险分担程度。在2003-2008年时间段上,金融深化对消费的风险分担程度的影响并不明显,只有微弱的证据表明,信贷市场发展在该阶段提高了各省人均居民消费的风险分担程度。而证券市场发展对消费的风险分担程度的影响一直不明显。     

STANDARDIZATION IN THE WIRELESS INTERNET MARKET: LESSONS FROM JAPAN AND KOREA

The wireless Internet market has been growing rapidly since NTT DoCoMo first introduced the service in 1999. This paper provides a framework within which the wireless Internet market can be analysed so as to draw valuable policy implications. We show that if platforms are standardized: (i) social welfare is increased with the rational expectation of larger installed bases; (ii) the neutrality of a revenue‐sharing ratio that is valid for non‐standardized network platforms is affected; and (iii) the collusive interconnection charge is lower than the social optimum insofar as the population mass of content providers is less dense than that of Internet users.     

Disasters,Household Decisions,and Insurance Mechanisms: A Review of Evidence and a Case Study from a Developing Country in Asia

This article investigates whether and how Asian people's exposure to a variety of disasters undermine their decisions and welfare. Our case study from Vietnam, based on household panel data, shows that households adopt a variety of coping strategies against the damages caused by disasters especially through credit and labor markets. While the consumption risk sharing networks function effectively at the commune level, market and non‐market insurance mechanisms are not sufficient, especially at the regional, national, and international levels. Hence, it is imperative to strengthen market, government, and community based insurance mechanisms to diversify aggregate disaster risks at the individual, national, and regional levels in Asia.
