Asymmetric trade protection leading not to productivity but to export share change

This article revisits a classical theme in economics, that is, the relationship between trade protection and economic performance, with an improved treatment of the endogeneity of tariffs and with consideration of alternative performance criteria. This paper also considers the effects of asymmetric protection, such as higher tariffs on consumer goods and lower tariffs on producer goods. Using sectoral data on Korean manufacturing during the period from 1967 to 1993, this study finds that the effect of trade protection by tariff tends to show up not in terms of total factor productivity but in terms of revealed comparative advantage and export shares of sectors. Such an effect tends to be greater in consumer goods, which are the main targets of promotion by higher tariffs. This study verifies the potentially positive role of tariffs under certain conditions, especially under discipline from world markets.     

The switchover to digital broadcasting in Korea

This study investigates the development of Korean digital TV transition by tracing the interaction between social and technological entities from various perspectives at different developmental stages. A socio-technical analysis examines the dynamic interactions among the stakeholders in the switchover to digital broadcasting, showing how the various actions taken by leading stakeholders affect diverse groups of stakeholders. The overall findings show that Korean digital TV transition is the outcome of a proactive strategy by industry stakeholders and the Korean government's top–down policy of supporting such a transition. It is argued that the policy of a top–down transition, which overlooks coordination among stakeholders, harms consumers and hinders effective and sustainable development. The case of Korea has implications for other countries that are pursuing digital transition strategies.     

Factors affecting trust between Korean IT firms and their Chinese counterparts

Trust is important in that it facilitates relational exchanges by permitting partners to transcend short-run inequities or risks to concentrate on long-term profits or gains. This study investigates what factors affect the trust between distribution-channel members, principally those between Korean IT firms and their exporting partners in China. We suggest that factors affecting trust include reputation, size, expertise, length of the relationship, communication, and satisfaction with previous outcomes of conflict episodes. Data were collected through a survey of 128 Korean IT firms, which have export-transaction relationships with Chinese buyers. The data strongly support the research hypotheses. As hypothesized, the results of data analysis show that reputation, communication, and satisfaction with previous outcomes tend to enhance trust. Additionally, we noticed that trust seems to decrease as the experience of conflict episodes increases.     

Optimal Exit Costs of Foreign Direct Investment

This paper examines the optimal policy on exit costs of foreign direct investment for a host country considering the impact of varying income level and host country’s risk aversion against volatile FDI flows. Based on a dynamic model about the impact of the exit costs on FDI inflows and capital formation, we demonstrate that a host country should determine the exit cost considering two counterbalancing factors, that is, facilitating higher FDI inflows and reducing volatility of FDI inflows. When a host country is less vulnerable to volatility with inelastic risk aversion against FDI volatility, it is optimal for the host country with a negative income shock to take a more aggressive approach to induce FDI inflows by lowering exit costs. However, if the host country is more vulnerable to volatility with elastic risk aversion, the host country is advised to take a conservative approach by increasing exit costs to reduce FDI volatility. These findings, supported by the OECD data on 42 countries’ exits costs, implicate that developing countries are recommended to lower exit costs to induce higher FDI inflows when they are not highly vulnerable to volatility shocks.     

Warranties as a device to extract rent from low‐risk users of a product

We develop a simple model that provides a new rationale for why a monopolist should bundle its product with a warranty even when all parties are risk neutral. In our model, a risk‐neutral monopolist faces two types of risk‐neutral consumers—low‐risk users that are unlikely to cause product failure and high‐risk users that are more likely to cause product failure. We find that when the firm fails to provide a warranty, a low‐risk user acquires a strictly positive rent by pretending to be a high‐risk user and receiving a price discount. By imposing a warranty, however, the monopolist can increase the price to high‐risk users, which in turn removes the incentive for a low‐risk user to pretend to be a high‐risk user, and the firm successfully extracts rent from the low‐risk user.

International environmental agreements under uncertainty

Negotiations toward international environmental agreements takeplace under uncertainty. We address the process of coalitionformation in this context. Coalitions are more likely to formamong countries which are similar. Since countries are morelikely to be facing similar conditions ex ante rather than expost, (i.e. before the resolution of uncertainty rather thanafter it), the possibility of coalition formation is enhancedthe sooner the negotiations take place. The social value ofbetter scientific information may well be negative in such circumstances.     

Depth of knowledge and the effect of higher order uncertainty

Summary A number of recent papers have highlighted the importance of uncertainty about others' information in models of asymmetric information. We introduce a notion that reflects the depth of knowledge in an information system. We show how the depth of knowledge can be used to bound the effect of higher order uncertainty in certain problems. We further provide bounds on the size of bubbles in finite horizon rational expectations models where the bounds depend on the depth of knowledge.We thank Dov Samet for pointing out an error in an earlier version.     

Does exchange rate variability matter for welfare? A quantitative investigation of stabilization policies

This paper studies what degree of exchange rate stabilization is optimal for several types of open economies. This is accomplished through a quantitative evaluation of optimal monetary policy rules in a two-country sticky-price model. First, a calibrated benchmark model with incomplete asset markets supports past conclusions from simpler models, emphasizing inflation stabilization rather than exchange rate stabilization. It also highlights that the utility gains from optimal stabilization policy are small. Second, while an economy extended to include consumer habits implies greater sensitivity by households to consumption variability, it has only minor effects on the benchmark conclusions and benefits. Finally, these conclusions are altered under an alternative environment where international asset markets exhibit asymmetry in the form of “original sin.” Such countries can benefit from policies that aggressively stabilize the exchange rate, with utility gains larger than the previous cases.     

Consumer ethnocentrism: A test of antecedents and moderators

This article identifies theoretical antecedents of consumer ethnocentricity and the effect ethnocentricity has on evaluations toward importing products. Hypotheses pertaining to the relationship between the identified antecedents and consumer ethnocentricity are developed based on an extensive review of the ethnocentrism and country-of-origin literatures. Also identified are factors moderating the effect of ethnocentric tendencies on consumers’ attitudes toward importing products. The hypotheses are subjected to an empirical test using data collected in Korea.

Does One Soros Make a Difference? A Theory of Currency Crises with Large and Small Traders

Do large investors increase the vulnerability of a country to speculative attacks in the foreign exchange markets? To address this issue, we build a model of currency crises where a single large investor and a continuum of small investors independently decide whether to attack a currency based on their private information about fundamentals. Even abstracting from signalling, the presence of the large investor does make all other traders more aggressive in their selling. Relative to the case in which there is no large investor, small investors attack the currency when fundamentals are stronger. Yet, the difference can be small, or non-existent, depending on the relative precision of private information of the small and large investors. Adding signalling makes the influence of the large trader on small traders' behaviour much stronger.
