### Summary and key findings
- The paper analyzes the informational efficiency of OTC currency options on the Czech koruna and the Polish zloty correcting for the volatility risk premium and errors-in-variable problems, using state-of-the-art techniques (Chernov 2001).
- It finds that these markets are more efficient than mature markets.
- Possible explanation: higher relative participation of informed dedicated investors, which offset the effects of relative illiquidity and higher transaction costs in these countries.
- Implied volatilities generally anticipate the direction of volatility correctly, with a bias to overpredicting volatility increases reflecting one-sided markets.

### Methodology
- Corrections applied for the volatility risk premium and errors-in-variable problems.
- Techniques referenced: Chernov 2001 (described as state-of-the-art in the paper).

### Implications and interpretive points
- Higher measured informational efficiency in these emerging market OTC options may reflect market structure characteristics (greater share of informed dedicated investors) rather than lower transaction costs or greater liquidity.
- The observed bias of implied volatilities to overpredict volatility increases is consistent with one-sided market conditions.
