Trade liberalization and the environment: The case of intra-industry trade

Abstract

While a large body of literature examines the environmental impact of trade on the environment, this discussion focuses largely on the context of inter-industry trade. Empirical evidence has long suggested that an increasing share of international trade takes the form of intra- rather than inter-industry trade. In an attempt to fill this gap, the present paper uses a price-setting duopoly model of intra-industry trade to highlight the environmental consequences of trade liberalization when oligopolistic rivalry rather than comparative advantage drives international trade. We find that the environmental impact of trade liberalization depends mostly on two factors, namely, on the nature of pollution (i.e. whether it is local, transboundary or global) and on which country liberalizes trade (i.e. whether it is the ‘clean’ country or the ‘dirty’ country).     

Do Traditional Chinese Cultural Values Nourish a Market for Pirated CDs?

On one hand, Chinese consumers are well known for conspicuous consumption and the adoption of luxury products and named brands. On the other hand, they also have a bad reputation for buying counterfeit products. Their simultaneous preferences for two contrasting types of product present a paradox that has not been addressed in the literature. This study attempts to present an explanation of this paradox by examining the effects of traditional Chinese cultural values and consumer values on consumers’ deontological judgment of pirated CDs and the amount of social benefits they perceive they gain from them. We interviewed 300 Hong Kong Chinese consumers, and found that face consciousness increased materialism and risk aversion, thereby producing a favorable deontological judgment of pirated CDs. Face consciousness also has a direct effect on the amount of social benefits perceived in pirated CDs. Both favorable deontological judgment and perceived social benefits contributed to a strong intention to buy pirated CDs. The results are discussed in a cultural perspective.     

Chinese firms’ crash risk and CEO media exposure

This study uses panel data from China over the period 2008–2015 to examine the effect of CEO media exposure on crash risk. We show that CEO media coverage in Chinese firms has a wide dispersion and mitigates crash risk at firms. Our study confirms the important role of media to monitor effectively firm behaviours in China.     

Ownership,two-tier board structure,and the informativeness of earnings – Evidence from China

This study extends previous research by empirically examining how ownership, two-tier board structure, and auditor affect the informativeness of earnings for companies listed in China. We measure the informativeness of earnings by the earnings–returns relation, discretionary accruals, and audit opinion. The results show that ownership concentration, the presence of foreign shareholders, the percentage of tradable shares, the type of dominant shareholder, the supervisory board, and independent directors affect the earnings response coefficients and discretionary accruals. We also find that the type of dominant shareholder, the size of the supervisory board, and the percentage of independent directors have an impact on the frequency of modified audit opinions. Our research has implications for China’s regulators who are striving to improve accounting information, transparency, and corporate governance.     

Equity diversification among the four Asian NICs

Recent studies have indicated the potential gains to U.S. investors from international portfolio diversification. Due to the rapid growth of the four Asian newly industrialised countries (NICs), namely, Hong Kong, Singapore, South Korea and Taiwan, it is believed that U.S. investors will become increasingly interested in these equity markets. The purpose of the present study is to investigate from the U.S. perspective, the prospects of diversifying across the countries. The results indicate that a diversified portfolio among these markets yields a higher return-to-risk ratio than investing in the U.S. market alone.The authors are with the School of Management, National University of Singapore.     

Deviations from Purchasing Power Parity

This study uses univariate and multivariate unit root tests to analyze the random walk behavior of real exchange rates for the period 1979–1989. The univariate test fails to reject the random walk model, but the multivariate test indicates that part of the real exchange rates is predictable, a result supporting purchasing power parity. Further analysis of the random walk component in real exchange rates shows that it is quite persistent: for all currencies it takes about five to eight years for this shock to diminish to half its size.     

Testing Calendar Effects of International Equity and Real Estate Markets

There are a lot of previous studies on calendar effects. However, most of them use traditional methods like regression. Hui et al. Habitat International 48, 38–45, (2015b) incorporated Shiryaev-Zhou index with logistic regression to study the Halloween and January effects of eight securitized real estate markets, but they fixed the moving-window size to be 130 days. How the change in moving-window size affects the calendar effects cannot be seen. In this study, we also apply the Shiryaev-Zhou index, but we allow the moving-window size to vary. Furthermore, we incorporated Shiryaev-Zhou index with analysis of mean (ANOM) and logistic regression to examine calendar effects of general equity and securitized real estate indices of Hong Kong, Japan, US, UK, France and Germany during the period 1996 – 2014. The results show that our new methods can detect additional channels of significant calendar effects of which normal methods fail to show. Furthermore, the general equity indices show significant Halloween and January effects. However, for the securitized real estate indices, the Halloween and January effects are less significant or even go into reverse in some cases. This study has two main implications. Firstly, investors can formulate a better trading strategy to earn more profits. Secondly, trends and phenomena found in equity markets may not be applicable to real estate markets, so investment rules on equity markets may not work on real estate markets.     

Pricing and Hedging of Discrete Dynamic Guaranteed Funds

We derive a risk‐neutral pricing model for discrete dynamic guaranteed funds with geometric Gaussian underlying security price process. We propose a dynamic hedging strategy by adding a gamma factor to the conventional delta. Simulation results demonstrate that, when hedging discretely, the risk‐neutral gamma‐adjusted‐delta strategy outperforms the dynamic delta hedging strategy by reducing the expected hedging error, lowering the hedging error variability, and improving the self‐financing possibility. The discrete dynamic delta‐only hedging not only causes potential overcharge to clients but also could be costly to the issuers. We show that a naive application of continuous‐time hedging formula to a discrete‐time hedging setting tends to worsen these possibilities.     

The optimal disposition decision for product returns

We provide an analytic model for the optimal disposition decision for product returns. The manager decides which product returns to accept for processing at the remanufacturing facility, and which ones to sell immediately as-is at a salvage value. High congestion levels in the remanufacturing facility delay the sale of the remanufactured product at the secondary market, decreasing the value at which it can be sold; this may imply a more attractive salvaging option. This is particularly important for high-tech products with short life cycles, such as computers and printers. We propose a two-step policy. In the first step, the returned product’s random processing time is observed. In the second step, a disposition decision is made: if the processing time is larger than a threshold k* the product is salvaged; otherwise the product is remanufactured. We provide an approximate procedure to compute k* in industrial settings. Our numerical study demonstrates the superiority of our policy over the current industrial practice ignoring the time value of money.
