Strategic alliances: a hospitality industry perspective

The article focuses on strategic alliance theory as it applies to the hospitality industry. Citing research as well as real-world examples, the authors integrate a variety of concepts and develop four propositions about the growing use of strategic alliances in the hospitality industry. These propositions include the following: P1: Hospitality alliances will evolve from equity joint ventures to collaborative joint ventures (non-equity) as competitor alliances will emerge. P2: Contractual agreements will evolve from simple franchise and management contracts to more complex resource-sharing, non-equity agreements. P3: Complex resource sharing between allying partners will help incumbent firms build relationships with partner firms that will lead to the development of competitor alliances. P4: Technology will help in the development of competitor alliances, which will also help to increase incumbent firms’ productivity and profitability.

Bayesian networks for identifying incorrect probabilistic intuitions in a climate trend uncertainty quantification context

Abstract

Probabilistic thinking can often be unintuitive. This is the case even for simple problems, let alone the more complex ones arising in climate modelling, where disparate information sources need to be combined. The physical models, the natural variability of systems, the measurement errors and their dependence upon the observational period length should be modelled together in order to understand the intricacies of the underlying processes. We use Bayesian networks (BNs) to connect all the above-mentioned pieces in a climate trend uncertainty quantification framework. Inference in such models allows us to observe some seemingly nonsensical outcomes. We argue that they must be pondered rather than discarded until we understand how they arise. We would like to stress that the main focus of this paper is the use of BNs in complex probabilistic settings rather than the application itself.     

A core-theoretic solution for the design of cooperative agreements on transfrontier pollution

For a simple economic model of transfrontier pollution, widely used in theoretical studies of international treaties bearing on joint abatement, we offer in this paper a scheme for sharing national abatement costs through international financial transfers that is inspired by a classical solution concept from the theory of cooperative games—namely, the core of a game. The scheme has the following properties: total damage and abatement costs in all countries are minimized (optimality property), and no coalition or subset of countries can achieve lower total costs for its members by taking another course of action in terms of emissions or transfers, under some reasonable assumption about the reactions of those not in the coalition (core property). In the concluding section economic interpretations of the scheme are proposed, including its connection with the free-riding problem.     

Why Chinese Exports Face So Many Trade Remedy Actions: An Empirical Study Based on Multi‐country and Multi‐industry Data

This paper offers a comprehensive analysis of the reasons for the large number of trade remedy actions taken against China. Using a multi‐country and multi‐industry dataset, the present paper shows that the macroeconomic situation of China's partners has a great influence on the probability of trade frictions arising with China. Moreover, the more powerful the industry is, the more likely it is to take trade remedy actions against China. The empirical results reveal that China has been hurt under the operating mechanism of the WTO, and the number of free trade agreements is negatively related to the initiation and approval of trade remedy actions. Basically, the determinants for countervailing and double remedy measures are identical, while they are different from determinants of antidumping measures. Accordingly, strengthening communication with trade partners will alleviate friction between China and its trade partners. Meanwhile, making use of foreign lobbies' power, actively integrating into the international trading system and participating in regional trade agreements are effective ways for China to deal with the “new normal” of trade frictions.     

The effects of regional trade agreements on FDI by its origin and type: Evidence from U.S. multinational enterprises activities

The effects of regional trade agreements (RTAs) on foreign direct investment (FDI) depend on both the origin and type of FDI. To estimate the various effects of RTAs, I differentiate between various types of FDI by using data on the sales destinations of foreign subsidiaries of U.S. multinational enterprises (MNEs), while also addressing the endogeneity of RTA formation. Consistent with the theory of MNEs, I find that RTAs reduce horizontal FDI from intra-RTA countries and increase export-platform and total FDI from extra-RTA countries. Moreover, the overall effects of RTAs are positive for extra-RTA FDI, but inconclusive for intra-RTA FDI. The results also support the effect of integrated markets’ economies of scale in inducing extra-RTA FDI.

The impact of 11/13 Paris terrorist attacks on stock prices: evidence from the international defence industry

This study explores the effect of the Paris terrorist attacks on the stock returns and the volatility for the most important companies in the global defence industry. To this end, it employs the General Autoregressive Conditional Heteroscedasticity methodology. The findings clearly indicate that this terrorist event has a positive impact on both the returns and the volatility of these stocks.     

对中国入世“经济增长危害论”的反思

中国加入WTO引发了一些对入世可能影响新世纪经济增长的悲观论调，我们认为关税减让的负面影响可由强化海关监管来减弱；对产业的冲击可能引发全局性结构调整；对农业的冲击可以由切实减轻农民负担来得以根本缓解；对金融业的冲击可通过加速公平税负和规范竞争环境来释放；对信息业的冲击可能带来行政垄断的终结，中国入世必然需要慎思谨行，但不宜悲观疑惧。
