Microeconomics uses statistical and mathematical methods to analyze the economic state of a society at an individual or company level. Binary models, such as logit and probit, are commonly used in microeconometrics to predict outcomes based on available data. The focus of microeconometrics has changed over time due to increased computing power and detailed census data. Despite these changes, microeconometrics still focuses on distributive nature, non-linear methods, and determining causality.
Microeconomics is a statistical and mathematical approach to looking at the economic state of a society at an individual level, or at the level of just one company instead of using broader economic trends. The collected data is used to predict the motivations and economic activities related to social science research. Some of the statistical methods used include non-linear modeling, searching for causality rather than simply associating data, and making inferences or logical hypotheses based on limited distributions of the available information. Micro-scale econometric models also sometimes simplify the analysis to get a clearer understanding of their meaning through binary approaches or test what happens when a influences b.
Binary models are common in theoretical economics, and two types of these models that are frequently used in microeconometrics include logit and probit models. Logit, or logistic regression model, is a form of regression analysis that takes data and tries to predict outcomes with it, such as basing a customer’s willingness to buy a new car or not on their income, age, and size of the family. Probit modeling is also a form of linear regression with a simpler binary component that tries to predict the maximum probability of one of two outcomes, such as whether an individual is married or not, based on available probit regression data.
The value of binary econometrics models rests in the fact that the data is not inadvertently choice-based sampling, where one group is favored over another. Biases can also enter if the choices studied were made by only a relatively small sample of the larger population. It is possible to compensate for such errors by using or including the additive random utility model (ARUM) in microeconometric trend analysis instead.
Statistical methods on the microeconometric scale have been around for a long time. Initially, they were used in the mid-1800s to analyze household budget data, and research continued with them into the 1950s to study commercial production levels and consumer demand. From the 1980s to the 21st century, the nature of microeconometrics and its focus have changed. This is largely due to increased computing power for mathematical analysis, coupled with much more detailed census data on populations.
Technology such as laser scanners in retail stores and corporate analysis of business trends, such as an airline’s records in its online passenger bookings, have led to an explosive capacity for microeconometrics. Despite the large databases of information that have arisen and the more complex mathematical models that are used to analyze them, microeconometrics still focuses on several fundamental aspects of analysis. These include the distributive nature of the data, non-linear methods of examining it, and an attempt to determine the causality of actions on simple correlative relationships between the information itself.
