What internal and external factors determine employee pay?

"Compensation, which includes both pay and benefits, is closely connected to performance appraisals. Employees who perform better tend to get bigger pay raises. Several factors affect an employee’s pay: Pay structure and internal influences. Wages, salaries, and benefits are based on skills, experience, and the level of the job. The most important high-level positions, such as president, chief information officer, and chief financial officer, are compensated at the highest rates. Likewise, different jobs of equal importance to the firm are compensated at similar rates. As the level of management responsibility increases, so does pay. For instance, if a drill-press operator and a lathe operator are considered of equal importance, they may both be paid $21 per hour. Pay level and external influences. In deciding how much to pay workers, the firm must also be concerned with the salaries paid by competitors. If competitors are paying higher wages, a firm may lose its best employees. HR professionals regularly evaluate salaries by geography, job position, and competitor and market wages. Wage and salary surveys conducted by the U.S. Chamber of Commerce and the U.S. Department of Labor can also be useful. There are also several websites such as Glassdoor that post salaries for jobs by company. An employer can decide to pay at, above, or below the going rate. Most firms try to offer competitive wages and salaries within a geographic area or an industry. If a company pays below-market wages, it may not be able to hire skilled people. The level of a firm’s compensation is determined by the firm’s financial condition (or profitability), efficiency, and employee productivity, as well as the going rates paid by competitors. For example, MillerCoors Brewing Co. is considered a high-paying firm ($29–$33 per hour for production employees)."
