10. Information Failure

(0)
The fifth in a series of study resources on Microeconomics that will provide an understanding on market failure and it’s causes. This study resource takes a look at how information failure – a type of market failure – can occur because both individuals or firms have a lack of accurate or relevant information required to make informed economic decisions. Causes of information failure Asymmetric information (Adverse selection and moral hazard) Methods to resolve information failure Behavioral insights and nudge theory

(0)
The first in a series of Microeconomics study resources that looks at consumer behavior theory , a branch of microeconomics that seeks to understand how individuals make decisions regarding the purchase, consumption, and disposal of goods and services. It explores the factors and processes that influence consumers’ choices, preferences, and behaviors in the marketplace. This resource takes a look at utility, and how any rational consumer decides to purchase and use a product/service with the primary aim of maximizing their satisfaction or benefit. It covers Utility (Total, average and marginal utility) Law of diminishing marginal utility Relationship between marginal utility and the demand curve Principal theories of utility (Ordinal and cardinal utility) Limitations of theory of utility

The second in a series of study resources on Microeconomics that looks at how governments can intervene in the free market in order to change free market outcomes, mostly for the better (e.g. maximizing social welfare). This study resource takes a look at buffer stocks, and how they are implemented by governments in order to guard against any unplanned shortages, as well as stabilize prices in an entire economy or an individual market.
23. The Short Run

23. The Short Run

(0)
The second in a series of Microeconomics study resources that looks at*** firm theory***, also known as the theory of the firm, a fundamental concept in economics that seeks to understand the behavior and decision-making processes of firms within an economy. It is a crucial part of microeconomics and provides insights into how businesses operate, produce goods and services, and interact with the market and other economic agents. This resource looks at the short run, a certain time period within the future where at least one input is fixed while others are variable. It looks at: Production function (Total, average and marginal product) Short-run production function (Law of diminishing returns)
22. Cost Theory

22. Cost Theory

(0)
The first in a series of Microeconomics study resources that looks at firm theory, also known as the theory of the firm, a fundamental concept in economics that seeks to understand the behavior and decision-making processes of firms within an economy. It is a crucial part of microeconomics and provides insights into how businesses operate, produce goods and services, and interact with the market and other economic agents. This resource looks into the concept of cost associated with production. It looks at: Fixed and variable costs Total, average and marginal costs
24. The Long Run

24. The Long Run

(0)
The third in a series of Microeconomics study resources that looks at firm theory, also known as the theory of the firm, a fundamental concept in economics that seeks to understand the behavior and decision-making processes of firms within an economy. It is a crucial part of microeconomics and provides insights into how businesses operate, produce goods and services, and interact with the market and other economic agents. This resource looks at the long run, a situation where all main factors of production are variable. It also looks at: Economies of scale (Internal & External) Diseconomies of scale Long run average cost curve (Returns to scale)
18. Consumer Equilibrium

18. Consumer Equilibrium

(0)
The second in a series of Microeconomics study resources that looks at consumer behavior theory , a branch of microeconomics that seeks to understand how individuals make decisions regarding the purchase, consumption, and disposal of goods and services. It explores the factors and processes that influence consumers’ choices, preferences, and behaviors in the marketplace. This resource looks at consumer equilibrium, and how it helps consumers maximize their utility when they spend their given income on one or more commodities, and have no urge to change this level of consumption, given the prices of commodities. It covers: Consumer equilibrium in the case of a single commodity Consumer equilibrium in the case of two or more commodities
16. Government Failure
lifegame828lifegame828

16. Government Failure

(0)
This study resource takes a look at government failure; how microeconomic intervention by the government to resolve market failure can result in an even greater net loss of economic welfare, as well as the causes and effects of government failure such as: Imperfect information Undesirable incentives Policy conflict Excessive administration costs Unintended consequences
