The effect of code-sharing alliance formations and terminations on firm value: The role of co-specialization and scope extension

This paper examines how alliance co-specialization and scope extension affect firm value at the time of alliance formation and termination, and whether value creation upon alliance formation also explains value creation upon termination. Building on the relational view of the firm, we develop predictions that are tested using event study methodology and data on code-sharing alliances formed, extended, and terminated between 1994 and 2008. The findings suggest that from a stock market perspective alliance formation and termination can be seen as two interrelated events and that it is difficult to reverse initial valuations past the alliance formation phase. They also suggest that the stock market reacts to alliance formation more critically than to post-formation decisions such as alliance scope extensions and terminations.     

Trading gains: terms-of-trade and real-exchange-rate effects

This paper considers alternative measures of a country's trading gains, i.e., the extra income that it earns (or loses) as the result of changes in the relative prices relevant for international trade, and which makes up the difference between real gross domestic product (GDP) and real gross domestic income (GDI). Looking at both the Laspeyres and the Törnqvist aggregation, we show that the trading gains really consist of two components, a terms-of-trade effect and a real-exchange-rate effect. Nearly all national statistical agencies, receiving no firm guidance from international organizations in this matter, merely consider the first effect, which suggests that the so-called trading-gain estimates they publish are incomplete and misnamed. Even more seriously, it implies that the corresponding measures of real GDI they derive are conceptually flawed. A straightforward way to circumvent these difficulties is to use the gross domestic final expenditure price index as deflator when computing real GDI and the trading gains. Some numerical estimates for Australia are provided as an illustration. The paper also identifies the underlying linear and Translog real GDI functions for which the Laspeyres and Törnqvist terms-of-trade and real-exchange-rate effects are exact.     

The use of trading strategies by fund managers: some first survey evidence

A questionnaire survey has found that most fund managers rely on the strategies of buy-&-hold, momentum and contrarian trading. These strategies are typically applied mutually. Their use is rooted in the attributes and beliefs of the respective fund managers: buy-&-hold traders are fundamentally oriented, risk averse and are less (over)confident than others. Momentum traders appear as the least risk-averse professionals, going aggressively with the trend. Contrarian traders, however, show signs of overconfidence and peculiar risk aversion, both indicating difficulties in successful strategy implementation. The behavioural patterns revealed are not easily reconciled with efficient markets.     

Housing, taxation and retirement provision

This paper considers the tax treatment of housing and the issue of savings for retirement in the context of a simplified model that still allows key aspects of the household context to be realistically represented. A model is developed in which both housing and financial assets can be used as vehicles for household saving. Individuals face perfect capital markets and choose between owner-occupied and rented accommodations. For the model developed, it is shown that the tax advantage of owner-occupied housing is not fully removed even if imputed rents are subject to income taxation. However, deferred income taxation for both housing and savings in the form of financial assets would result in an equal treatment of tenants and owner-occupiers.     

Within the triangle of healthcare legacies: comparing the performance of South-Eastern European health systems

Objective: Inter-regional comparison of health-reform outcomes in south-eastern Europe (SEE).

Methods: Macro-indicators were obtained from the WHO Health for All Database. Inter-regional comparison among post-Semashko, former Yugoslavia, and prior-1989-free-market SEE economies was conducted.

Results: United Nations Development Program Human Development Index growth was strongest among prior-free-market SEE, followed by former Yugoslavia and post-Semashko. Policy cuts to hospital beds and nursing-staff capacities were highest in post-Semashko. Physician density increased the most in prior-free-market SEE. Length of hospital stay was reduced in most countries; frequency of outpatient visits and inpatient discharges doubled in prior-free-market SEE. Fertility rates fell for one third in Post-Semashko and prior-free-market SEE. Crude death rates slightly decreased in prior-free-market-SEE and post-Semashko, while growing in the former Yugoslavia region. Life expectancy increased by 4 years on average in all regions; prior-free-market SEE achieving the highest longevity. Childhood and maternal mortality rates decreased throughout SEE, while post-Semashko countries recorded the most progress.

Conclusions: Significant differences in healthcare resources and outcomes were observed among three historical health-policy legacies in south-eastern Europe. These different routes towards common goals created a golden opportunity for these economies to learn from each other.     

Trade creation and the status of FTAs: empirical evidence from East Asia

East Asia has been considered a latecomer with respect to Free Trade Agreements (FTAs). Since the turn of the last century, however, FTAs with East Asian participation have seen an intra- and extra-regional expansion. Many trade initiatives have been proposed, negotiated or even implemented. This introduces interesting perspectives for the analysis of trade agreements regarding their anticipatory trade effects. This paper focuses on the trade impact of FTAs at different stages that East Asian economies participate in. The central part of this study is an econometric analysis that applies panel data to the gravity model of international trade flows. We augment the traditional model with variables to estimate trade effects of bilateral and multilateral agreements and year-to-year changes in the stages of their implementation. Our results reveal that there exist anticipatory effects preceding the actual implementation of bilateral FTAs with East Asian participation. Further, anticipation effects are larger for bilateral than for multilateral agreements, possibly because the realisation of bilateral agreements is considered more realistic.     

EU Emission Allowances and the stock market: Evidence from the electricity industry

This paper constitutes - to our best knowledge - the first econometric analysis on stock market effects of the EU Emission Trading Scheme (EU ETS). Our results suggest that EU Emission Allowance (EUA) price developments matter to the stock performance of electricity firms: EUA price changes and stock returns of the most important European electricity corporations are shown to be positively related. This effect does not work asymmetrically, so that stock markets do not seem to react differently to EUA appreciations in comparison to depreciations. The carbon market effect is shown to be both time- and country-specific: It is particularly strong for the period of EUA market shock in early 2006, and differs with respect to the countries where the electricity corporations analysed are headquartered. Stock market reactions to EUA volatility could not be shown.
