Types of econometric theory?

Econometric theory uses a mix of mathematics, statistics, and economics to create models that can be used for business studies. Economists and other educated people can engage in these activities as higher degrees are often required to learn and understand these models. Different types of econometric theory include introductory, spatial, and nonparametric estimation. The different theories rely on the data collected to ascertain the information used to make decisions. In short, econometrics aims to provide the best data available for making decisions that present the least risk and the greatest economic rewards.

Introductory econometrics tends to be a much more basic set of models. The two underlying assumptions here include an inverse relationship between the price of an item and the quantity required – capital expenditures rise as interest rates fall, and there is a positive relationship between revenue and consumption expenditures. These factors are commonly part of each introductory theory and are based on econometric studies. Early studies in econometrics often focus on these attributes because companies often want to discover these relationships before moving on to more complex studies. While the econometrics study here and below may seem highly academic, it provides useful data for private companies and governments.

Spatial econometrics uses information gleaned from different data sets to create models for use in the business world. Data generates pieces of dependent data or related data from a larger population of information. Some attributes of this econometric theory include the decay of sample data with distance, observation similar to nearby observations, hierarchy, and a systematic change in parameters. These attributes may not show up in every single study surrounding spatial econometrics theory. Some of the attributes should be included, however, as this will define the study.

Nonparametric studies are a very common inclusion in econometric theory. In short, it is a general method used by reviewers to discover a functional module that fits all observed data. Since the main thrust of econometrics is to collect large sets of data to make statistical or mathematical assumptions, the use of non-parametric estimates is extremely common. When enough econometrics studies continue to collect and report similar data using nonparametric methods, a theory based on the stated assumptions will develop. Hence, econometric theory develops from the many studies of commercial activity that exist around a given data set.
