Regulation mandated by the government or state attempts to produce outcomes which might not otherwise occur, produce or prevent outcomes in different places to what might otherwise occur, or produce or prevent outcomes in different timescales than would otherwise occur. Regulations rarely produce complete outcomes or prevent outcomes completely but they generally do modify what would otherwise take place. Common examples of regulation include attempts to control market entries, prices, wages, pollution effects, employment for certain people in certain industries, standards of production for certain goods and services.
