This study tests for the law of one price and Grander Causality between the EU ETS and Nord Pool $CO_2$ allowance prices. The Johansen cointegration test shows that there exists a long run equilibrium between EU ETS and Nord Pool prices and support the law of one price. The Granger casuality test suggests that the EU ETS leads Nord Pool for all vintages traded. The test results imply that the EU ETS can be regarded as the representative carbon market in the EU where many exchanges just started competing for the newly rising market for carbon.

The Gang-Seo wholesale market is an experimental system in that two different distribution channels co-exist in the same marketplace; the auction system and the consignment system. The government expects the consignment system offers higher and more stable prices to farmers than the auction system. This study tested if that is the case, but the results did not support the hypotheses. The consignment system needs institutional complements and more transparent operations before wide-spreading.

We explore each of the three major domestic fishery product markets in South Korea- Frozen Squid, Frozen Hair tail and Dried Anchovy- to assess whether we can find evidence for Law of One Price (LOP) across the five major cities- Seoul, Dae-Jeon, Dae-Gu, Gwang-Ju and Busan. To achieve our aim, we utilize two different types of unit root tests: Augmented Dickey-Fuller (ADF) and Kwiatkowski-Phillips-Schmidt-Shin (KPSS) unit root test. In each of the three fishery product markets, we find evidence in support of LOP among several cities, which confirms that these markets are integrated to a certain extent. In particular, we find stronger evidence of LOP for Dried Anchovy market relative to the other two fishery product markets. Based on our findings, we argue that the Dried Anchovy market exhibits a greater degree of market integration across the five major cities in South Korea compared to the other two fishery product markets. The greater degree of market integration in the Dry Anchovy market is facilitated by its higher substitutability across cities; taken together these findings show that the market for Dried Anchovy in South Korea is more efficient than the markets for Frozen Squid and Frozen Hair tail.

The paper studies the degree of international price dispersion for 300 individual goods and services between cities of three country groups over 1999 and 2013, focusing on the role of oil prices in generating deviations from the law of one price. We find that while oil prices did not contribute to the trend in cross-country price dispersion, it does account for within-country price dispersion. Once the oil price effect is subtracted out, the remaining price dispersion between U.S. cities no longer exhibits a noticeable upward trend. If oil prices increase transportation costs, they should increase the deviations from the law of one price, raising price dispersion. Our findings indicate that this effect is more pronounced within a country, while factors such as elasticity of substitution and other trade barriers are likely to matter more in price dispersion across borders. We view our results as complementary to those that emphasize the role of time-varying factors in accounting for price dispersion.
