concentration ratios are used to determine total market shares within four specific industries. I will also discuss the levels of competition within those industries and how oligopolies can benefit society. Case‚ Fare‚ and Oster defines concentration ratio as the share of industry output in sales or employment accounted for by the top firms (2009). They are used to measure the total output produced by a certain number of firms within an industry. Four-firm concentration ratios are used

Profitability Ratios A class of financial metrics that are used to assess a business’s ability to generate earnings as compared to its expenses and other relevant costs incurred during a specific period of time. For most of these ratios‚ having a higher value relative to a competitor’s ratio or the same ratio from a previous period is indicative that the company is doing well. Gross Profit Margin A financial metric used to assess a firm’s financial health by revealing the proportion of

Identifying a Salt by Creating its Heating Curve Introduction: Solubility is a substance’s ability to be dissolved in a liquid‚ usually water‚ and some substances are more soluble than others. A solution can be saturated‚ unsaturated or supersaturated. Temperature plays a large role in the solubility of substances. For example‚ on table G of the Chemistry reference tables it shows that 10g of KClO3 will dissolve in 100g of water at about 25°C‚ but at about 48°C‚ 20g will dissolve. The higher the

For those of you who came to the review in class today‚ The stoichiometry question from class. I read the answer to the wrong decimal place. --What is the total mass of oxygen in 0.26mol of Cu2O? Find the percent of oxygen in Cu2O first. The molar mass of Cu2O is 143‚ the mass of just the oxygen in it is 16. % Composition of oxygen would be 16/143 times 100 is 11.19%‚ To determine the mass of Cu2O in 0.26 mol‚ multiply by the molar mass of Cu2O. This gives

INTRODUCTION Absence is the failure of a worker to report for work when he is scheduled to work. A worker is to be considered as scheduled to work when the employer has work available for him and the worker is aware of it. A worker is to be treated as absent for purpose of this absenteeism. Statistics even when he does not turn up for work after obtaining prior permission any worker who reports for duty even for a part of the day or shift should not be‚ counted among absentees.
