(Reuters) - Bankers can expect their bonus packages in 2011 to be 10 percent to 15 percent richer on average than last year, a widely followed compensation expert said on Friday on Reuters Insider.

Not everyone should expect that level of increase, however.

Asset managers and brokers will command the biggest increases this year, with incentive pay up by 20 percent or more from 2010, according to Alan Johnson, who has been tracking Wall Street pay for two decades as head of Johnson Associates.

Fixed income and equity traders, however, should not expect the same level of largesse from their employers, Johnson said, predicting traders' bonuses will be effectively unchanged from 2010.

Johnson's estimates are based on new research his firm expects to publish to clients next week and that he shared with Insider.

Johnson, on an Insider panel probing "The New Wages of Wall Street," said that while the conventional wisdom holds that banker pay is on a perpetual upward trajectory, compensation adjusted for inflation is not all that different from what it was 10 to 15 years ago.

He also said the current climate at banks is giving a recruiting advantage to boutique investment houses and private equity firms.
