If the income elasticity of demand for his bicycles is greater than one, it means for Dan's business that for every 1 % change in customers' income, their response in terms of spending on purchasing the bicycles is going to be larger than 1 %. Practically, given that the economy is forecasted to grow and therefore people will experience an increase in their income, for every 1 % increase in income, there is going to be a more significant higher spending on Dan's bicycles. Dan is likely to benefit significantly through increased revenue and if costs remain the same then also through increased profits.
