Trade Policy and Environmental Regulation in the Asia–Pacific: A Simulation

The Asia–Pacific Economic Cooperation (APEC) has the potential to become the world's largest free trade area, encompassing both developed and developing countries. At the same time environmental standards vary substantially in the region. A multilateral computable general equilibrium (CGE) model combined with environmental sub–models simulates the environmental effects of trade and environmental policy changes. The simulations show: (i) Even drastic reductions in trade barriers have only a small effect on pollution; (ii) Low environmental standards relative to trade partners do not necessarily result in increased pollution when trade is liberalised; (iii) Unilaterally raising environmental standards does not crowd out pollution to countries with laxer standards.     

亚太新双边主义兴起的原因研究——一个政治经济学的分析视角

亚太地区双边贸易协定的兴起与演进形成当代亚太区域经济合作发展的新阶段,其意义和影响日益受到国际社会的普遍关注。本文以政治经济学方法为分析工具,对亚太地区双边主义兴起的动因进行剖析和评价,指出亚太地区双边主义的形成是亚太地区各经济体在当前国际政治经济环境约束下,选择最大化自身利益的贸易政策的必然结果。中国应积极参与建立双边自由贸易区;发挥先发优势,谋求以我为主的区域经济一体化进程;协调国家战略与地区战略,平衡经济利益和政治利益。     

The Short– and Long–run Performance of New Listings in Tunisia

This study examines abnormal stock market returns of new listings on the Tunisian Stock Exchange. Substantial positive abnormal returns are found on the first listing day and this finding is similar to that obtained in other countries. Subsequent performance is poor and investors who bought shares at the close of trading on the first day would have lost about 22% against the Tunis Stock Exchange index over a three–year period. The possible causes of this are investigated. Among the factors found in the literature that possibly affect the level of long–term performance, only the state of the IPO market, the initial return, the delay in reaching the ‘first market price’ and the size of the firms have significant coefficients. This result is supportive of the traditional fad’s interpretation of long–term underperformance.     

Bilateralism, multilateralism, and the quest for global free trade

We develop an equilibrium theory of trade agreements in which both the degree and the nature (bilateral or multilateral) of trade liberalization are endogenously determined. To determine whether and how bilateralism matters, we also analyze a scenario where countries pursue trade liberalization on only a multilateral basis. We find that when countries have asymmetric endowments or when governments value producer interests more than tariff revenue and consumer surplus, there exist circumstances where global free trade is a stable equilibrium only if countries are free to pursue bilateral trade agreements. By contrast, under symmetry, both bilateralism and multilateralism yield global free trade.     

Female Entrepreneurs,Work–Family Conflict,and Venture Performance: New Insights into the Work–Family Interface*

Existing theory is extended to predict the effectiveness of strategies for structurally reducing work–family conflict by manipulating roles, given the salience of work and family roles and resources available to the female entrepreneur. A conceptual framework based on the constructs of role involvement and role conflict is used to examine whether high‐growth female entrepreneurs choose more appropriate strategies for reducing work–family conflict than their less successful counterparts. Three basic strategies for manipulating roles are discussed: (1) role elimination; (2) role reduction; and (3) role‐sharing. The following propositions are advanced: (1) work–family management strategies are a significant determinant of venture growth; (2) women who develop high‐growth businesses more effectively reduce work–family conflict by choosing strategies better matched with their internal needs and access to external resources than less successful women; and (3) role‐sharing strategies are preferred because they allow women to enjoy the enhancement of both work and family roles while reducing the level of inter‐role conflict. As a result, the high prevalence of team‐building and participative management practices observed in women‐owned businesses may be driven by the need for female entrepreneurs to manage work–family conflicts as well as genetics or socialization.     

A Leibenstein–Hobbes–Walras Model of Sharecropping

Circumstances under which share tenancy may emerge as a socially viable and incentive-compatible system of land-labor exchange are explored in a model incorporating Leibenstein’s nutrition-effort hypothesis, limited substitution possibilities and endogenous distribution. The model provides a Walrasian resolution of the traditional conundrum of production control under sharecropping. It is shown that a pure sharecropp ing equilibrium with tenant control exists when land is relatively abundant though land rent is zero under either a fixed-rent or wage system. With land relatively scarce, a nearly-symmetric equilibrium with landlord control also exists provided workers share income in the presence of unemployment.     

Current Account ‘Core–Periphery Dualism’ in the EMU

Current account (CA) dispersion within European Union (EU) Member States has been increasing progressively since the 1990s. Interestingly, the persistent deficits in many peripheral countries have not been accompanied by a significant growth process able to stimulate a log run rebalancing as neoclassical theory predicts. To shed light on the issue, this paper investigates the determinants of Eurozone CA imbalances, focusing on the role played by financial integration. The analysis considers two samples of 22 OECD and 15 EU countries, three time horizons corresponding to various steps in European integration, different control variables and several panel econometric methods. The results suggest that within the EU group of countries financial integration contributed to explain the CA deterioration in the peripheral countries especially in the post‐EMU period creating an asymmetric behaviour within the EMU. From a financial stability perspective, this ‘divergence’ could hinder the effectiveness of monetary policy. By reducing the apparent benefits of participating in the monetary union, it also raises the risk of a break‐up.     

Intellectual Property Rights in Agriculture and the Interests of Asian‐Pacific Economies

This paper describes recent and ongoing processes of technological change in agriculture, which has become a highly R&D‐intensive sector in many countries of the Asia‐Pacific region. It also considers the role of various forms of intellectual property rights (IPRs) in promoting such technological changes and in affecting their diffusion through the region. A central part of the discussion is a review of how these various IPRs operate and are protected in major economies of the region. There is an assessment of the economic interests of key countries, including the United States, Canada, Australia, China, Japan and the Republic of Korea, in global and regional policy evolution in agricultural IPRs. These interests are a mix of comparative advantage in farming, which is quite distinctive among these countries, and the technological basis of production, which is more convergent. A review of available measures of innovation in the region suggests that all of these economies are active in developing new agricultural technologies, although there is considerable specialisation in the types of processes developed. Given this mix of divergence in comparative costs and convergence in technology interests, it is difficult to describe sharply the preferences these economies may have in continued globalisation of agricultural IPRs. However, the analysis points to some areas in which countries may continue to specialise – thereby retaining the ability to remain in specific areas of farming – and other fields in which international collaboration may be sensible.     

Revisiting the risk/return relations in the Asian Pacific markets: New evidence from alternative models

This paper examines the risk/return relations in eleven Asian Pacific stock markets and explores if the 1997 Asian financial crisis significantly influenced market behavior in the region. We use a plain vanilla time-series regression approach as well as various GARCH models. Although results significantly vary across model specifications, the overall evidence from GARCH models supports a significantly positive risk/return relation in several markets but only prior to the Asian financial crisis. These results accord with Glosten et al. (1993) and Harvey (2001) and suggest that the relative risk aversion is sensitive to both model specifications and structural breaks.     

GENERALIZATION OF THE DYBVIG–INGERSOLL–ROSS THEOREM AND ASYMPTOTIC MINIMALITY

The long‐term limit of zero‐coupon rates with respect to the maturity does not always exist. In this case we use the limit superior and prove corresponding versions of the Dybvig–Ingersoll–Ross theorem, which says that long‐term spot and forward rates can never fall in an arbitrage‐free model. Extensions of popular interest rate models needing this generalization are presented. In addition, we discuss several definitions of arbitrage, prove asymptotic minimality of the limit superior of the spot rates, and illustrate our results by several continuous‐time short‐rate models.     

Critique of the Corn–Guano Model

It is argued that the corn–guano model proposed by Bidard and Erreygers is too simple as a representation of Hotelling's theory because it does not reflect the distinction between the resource in situ and the extracted resource. The claim to have transposed the representation of Hotelling's theory from the neoclassical to a classical context is not warranted because normal prices are not used. The model is elegant in its simiplicity but it does not face the relevant problems of exhaustible resources posed by the real world.
