We analyze financial statements from 34 countries for the period 1984–1998 to construct a panel data set measuring three dimensions of reported accounting earnings for each country: earnings aggressiveness, loss avoidance, and earnings smoothing. We hypothesize that these three dimensions are associated with uninformative or opaque earnings, and so we combine these three measures to obtain an overall earnings opacity time-series measure per country. We then explore whether our three measures of earnings opacity affect two characteristics of an equity market in a country: the return the shareholders demand and how much they trade. While not all results are consistent for our three individual earnings opacity measures, our panel data tests document that, after controlling for other influences, an increase in overall earnings opacity in a country is linked to an economically significant increase in the cost of equity and an economically significant decrease in trading in the stock market of that country.

This paper investigates the relation between differences in accounting standards across countries and foreign analyst following and forecast accuracy. We develop two measures of differences in generally accepted accounting principles (GAAP) for 1,176 country-pairs. We then examine the impact of these measures of accounting differences on foreign analysts. In so doing, we utilize a unique database that identifies the location of financial analysts around the world, creating a sample that covers 6,888 foreign analysts making a total of 43,968 forecasts for 6,169 firms from 49 countries during 1998–2004. We find that the extent to which GAAP differs between two countries is negatively related to both foreign analyst following and forecast accuracy. Our results suggest that GAAP differences are associated with economic costs for financial analysts.

We hypothesize that firms' 10-K market risk disclosures, recently mandated by SEC Financial Reporting Release No. 48 (FRR No. 48), reduce investors' uncertainty and diversity of opinion about the implications, for firm value, of changes in interest rates, foreign currency exchange rates, and commodity prices. We argue that this reduced uncertainty and diversity of opinion should dampen trading volume sensitivity to changes in these underlying market rates or prices. Consistent with this hypothesis, we find that after firms disclose FRR No. 48-mandated information about their exposures to interest rates, foreign currency exchange rates, and energy prices, trading volume sensitivity to changes in these underlying market rates and prices declines, even after controlling for other factors associated with trading volume. The observed declines in trading volume sensitivity are consistent with FRR No. 48 market risk disclosures providing useful information to investors.
