Media economics the application of economic theories, concepts and principles to study the macroeconomics and microeconomic aspects of most media consumption and industries, for academic lecturers, policymakers, and industry analysts. Media economics methods include how to apply variety of methodological approaches both qualitative and quantitative methods and statistical analysis, as well as studies using financial, historical and policy driven data.Some economists define land, labor, and capital as the three factors of production and the major contributors to a nation's wealth. Can land, labor and capital be as three main factors of production any books, newspapers, magazines etc. reading products in publishing industry? Some economists believed price was determined by the costs of production, whereas marginal economists equated prices with the level of demand can be any books, magazines, newspapers etc. reading products prices is either determined by the cost of printing production or equated any one kind of these reading products with the level of reader' demand more.The marginal economists contributed the basic analytic tools of demand and supply, consumer utility and the use of mathematics as analytical tools to develop microeconomics. Can apply the basic analytic tools of reader demand and the any one kind of these reading products supply and reading consumer individual reading need, utility and the use of mathematics as analytical tools to predict any kind of reading consumer numbers and reading interesting topic choice in media industry?However, some economists also demonstrated that given a free market economy, such as in free publish industry, the factors of production ( land, labor and capital) were important in understanding the economic system. Can apply the factor of production, e.g. publishing book sale location ( land); publishing book salespeople sale experience ( labor); and attractive book printing quality (capital printing expense) to influence the publishing industry reading consumer reading habit or purchase book activities?However, some economists suggested two important contributions: Analysis of monopoly and price discrimination and the market for labor will influence consumer number. Such as publishing case: Can analysis of which famous royalty publishing book sale firm to the most monopoly and then following its different topic of books sale price to evaluate whether how much every different topic of its similar book topic sale price to be higher to avoid reduce reader numbers, due to the not famous royalty book seller which similar topic book to the famous royalty book seller's prices are too higher than the famous royalty publishers' book prices? Book salespeople individual sale experience and sale ability and book knowledge ( labor supply) influence the book publishing shop's reading clients buying decisions, such as the more experience book sellers can persuade many readers to buy the book store's books. Otherwise, the less sale experience book sellers can not persuade many readers to buy the store's books.As the found in the field of economics, it became more refined, scholars began investigate many different economic concepts and principles to predict consumers behaviors, such as media reading customer. Nowadays, the media industries provides all of the elements required for studying the economic process. Content providers can offer information and entertainment, education etc. different topic books, magazine reading products which became the media publishing suppliers. Whereas, reading consumers and media advertisers formed the demand side of the media market.
