Deductive and inductive methods are two broad approaches to study in economics. The deductive method starts with a general theory or hypothesis and uses data to test it, moving from general to specific. It aims to test theories through a process of selecting a problem, formulating assumptions, developing hypotheses through logical reasoning, and verifying hypotheses. The inductive method gathers data and observations to develop broader generalizations and theories through a process of observing particulars and reasoning to identify patterns, form tentative hypotheses, and develop general conclusions, moving from specific to general. Both approaches have merits and limitations, and most economic research uses elements of both inductive and deductive reasoning.
Inductative ,deductive methods
- 1. Deductive v/s Inductive Method In Economics, we often refer to the two broad methods of study as the deductive and inductive Methods. Deductive Method aims at testing theories. It works Like this – general theory - and develop hypothesis test hypothesis to verify the general theory. Thus it begins with a hypothesis. Sometimes this is informally called a "top-down" approach. It is associated with quantitative research. We might begin with thinking up a theory about our topic of interest. We then narrow that down into more specific hypotheses that we can test. We narrow down even further when we collect observations to address the hypotheses. This ultimately leads us to be able to test the hypotheses with specific data -- a confirmation (or not) of our original theories. Deduction Means reasoning or inference from the general to the particular or from the universal to the individual. Deduction involves four steps: (1) Selecting the problem. (2) The formulation of assumptions on the basis of which the problem is to be explored. (3) The formulation of hypothesis through the process of logical reasoning whereby inferences are drawn. (4) Verifying the hypothesis. Merits of Deductive Method Demerits of Deductive Method Real Unrealistic Assumption Simple Not Universally Applicable Powerful Incorrect Verification Exact Abstract Method Indispensable Static Method Universal Deductive economics starts with a set of axioms about economies and how they work, and relies on these principles to explain individual cases or events. Supply and demand analysis, a staple in any introductory economics course, is an example of deductive reasoning because it involves a set of generally accepted principles about demand and supply. To summarize, deduction in economics starts with a generally accepted principle and proceeds to the specific Inductive Method: Induction “is the process of reasoning from a part to the whole, from particulars to generals or from the individual to the universal.” The problem Data Observation Generalization
- 2. Inductive approach is concerned with generation of new theories. It works like this – Gather data- look and then develop theory. It is associated with qualitative research. It works the other way, moving from specific observations to broader generalizations and theories. Informally, we sometimes call this a "bottom up" approach In inductive reasoning, we begin with specific observations and measures, begin to detect patterns and regularities, formulate some tentative hypotheses that we can explore, and finally end up developing some general conclusions or theories. Merits of Inductive Method Demerits of Inductive Method Realistic Mis-interpretation of Data Future enquiry Uncertainty Dynamic Lacks Concreteness Statistical Method Costly Method Indispensable Difficult to Prove Hypothesis Universal Controlled Experimentation not Possible Inductive reasoning in economics does the reverse of deductive reasoning; namely, it begins with an individual problem or question and proceeds to form a general principle based on the evidence observed in the real world of economic activity. For example, an economist who asks if a government program of public works spending will stimulate a region's economy will proceed to research the issue, collect and analyse data, and based on conclusions, form a general theory about the economic impact of fiscal policies. These two methods of study have a very different "feel" to them when you're conducting research. Inductive reasoning, by its very nature, is more open-ended and exploratory, especially at the beginning. Deductive reasoning is more specific in nature and is concerned with testing or confirming hypotheses. Even though a particular study may look like it's purely deductive most economic research involves both inductive and deductive reasoning processes at some time in the project. ******
