Anti‐dumping Duty and Firm Heterogeneity: Evidence from Korea

This study examines the imposition of anti‐dumping (AD) duties on imported products in Korea. We use panel data for Korean firms between 2000 and 2012 and estimate the firm‐level productivity of import‐competing firms before and after AD imposition. Using a difference‐in‐difference framework, we compare firm productivity changes in a treatment group that receives AD protection to a control group that does not. In contrast to recent findings on the effects of AD measures, we find that the average protected firms experience productivity loss during the AD protection period. Examining the changes in external market condition and internal resource allocation during the protection period, such loss appears to be more evident inside highly concentrated import‐competing sectors. Further, we find that protected firms are more likely to reallocate their resources abroad via FDI at the expense of domestic production and investment once they receive temporary protection.     

What makes you grab low carb beers?

What makes people choose low-carbohydrate, high-protein food (low-carb food), which is good for health but usually tastes bad? Using panel data on US beer consumption in which each consumption occasion is uniquely associated with various companion-based consumption contexts and exposure levels to diet information, we analyse the variations in consumers’ preferences for low-carb food. The results show that there exist considerable gender differences in the preference variation under peer pressure. First, single females behave in a way they dislike drinking low-carb beer in front of friends, spouses and significant others. Second, male (both married and single) and married females pretend to choose low-carb beer when accompanied by spouses or significant others. Finally, the elasticity of demand for healthy food with respect to news articles about low-carb diets is positive, yet with substantial differences in the degree of elasticity across demographic groups.     

Assessing the impact of green supply chain practices on firm performance in the Korean manufacturing industry

As a growing number of customers tend to view corporate social responsibility (CSR) as a key purchase decision criterion, demands for CSR including environmental sustainability have accelerated in today's business world. To meet such demands, many firms consider embracing environment-friendly business practices. However, many firms are still hesitant to implement those practices due to sceptical views about their real managerial benefits. Although the previous literature confirms the positive link between a firm's commitment to environmental sustainability and its performance, the varying degree of impact of different kinds of environment-friendly supply chain practices on the firm's operational performance is still unknown. To fill the void left by prior research, this paper aims to classify various types of green supply chain management (GSCM) practices and then assess the impact of each of these distinct types on the firm's operational performances (especially manufacturing and marketing performance). Also, this paper examines how the firm's organisational profiles such as firm size affect the particular firm's choice of GSCM practices. Our experimental results reveal that the chosen type of GSCM practices influences the firm's performance differently.     

Effects of the preference for environmental quality on the export competition between China and OECD countries

This study examines how importers’ preferences for environmentally friendly products influence the effect of China’s export growth on the exports of OECD countries to third markets. The effect of China’s export growth is systematically investigated using the theoretical gravity model, which assumes that importers’ environmental preferences are heterogeneous among countries. A new measure is also proposed to represent importers’ revealed preferences for environmental quality across countries. Panel data consisting of observations for 30 OECD exporting countries and 60 importing countries over the 2000–10 period confirm that the crowding‐out effect of China’s export growth on the exports of OECD countries observed in markets for consumption goods and the dampening effect observed in markets for intermediate goods are becoming weaker as the importer preference for environmental quality becomes stronger.     

Multi-period heterogeneous vehicle routing considering carbon emission trading

This study considers the problem of determining heterogeneous vehicle routes in each period of a given planning horizon while satisfying service combinations, customer demands and vehicle capacities. The objective is to minimize the sum of vehicle operation costs and carbon emission trading cost/benefit, where the trading cost is incurred to purchase the carbon emission right if the total emission exceeds an upper limit in each period, while the trading benefit can be obtained by selling the right in each period, otherwise. A mixed integer programming model is developed to formulate the problem mathematically. Then, a tabu search algorithm is proposed that incorporates the characteristics of the heterogeneous and the period vehicle routing problems while considering the amount of carbon emission in each period. Computational experiments were done on modified benchmark instances and additional random instances, and the results show that the multi-period approach outperforms the existing single-period one in overall average. In particular, the test results show that the multi-period approach can reduce carbon emission more significantly than the single-period one without sacrificing the total cost.
