When you are able to look at a specific set of data and form general conclusions based on existing knowledge from past experiences, you are using inductive reasoning. The deductive method derives new conclusions from fundamental assumptions or from truth established by other methods. Through observation, some of the theories of generalization are developed or refined with the help of statistical methods. A generalisation drawn under the inductive method is often histrico-relative in economics. Some of the recent macroeconomic researches like the nature of consumption function describing the relationship between income and consumption, acceleration principle describing the factors which determine investment in the economy have been obtained through the use of induction or empirical method. Under these conditions, the hypothesis may turn out to the wrong. In this method changing economic phenomena can be analyzed based on experiences, conclusions can be drawn and appropriate remedial measures can be taken. The second lipstick I ⦠Plagiarism Prevention 4. The next step in deduction is the framing of assumptions which are the basis of hypothesis. If the hypothesis is not confirmed, it can be argued that the hypothesis was correct but the results are contradictory due to special circumstances. For example: Since 95% of the left-handers Iâve seen around the world use left-handed scissors, 95% of left-handers around the world use left-handed scissors. Similar to inductive generalizations, statistical induction uses a small set of statistics to make a generalization. For this purpose, economists now use statistical and econometric methods. The chief merits of this method are as follows: The inductive method is realistic because it is based on facts and explains them as they actually are. Engel propounded the law only after he had studied several family budgets in Austria. Image Guidelines 5. They are the two forms of logic that are complementary and co-relative and help establish the truth. We then work out the relationship in these simplified systems and by introducing more and more complete assumptions, finally work up to the consideration of reality itself.” Thus, this method is nearer to reality. All observed dogs have fleas 2.3. Thus true progress in economic enquiries can be made by a wise combination of deduction and induction. Since the actual world is very complicated, “what we do is to postulate in our own minds economic systems which are simpler than reality but more easy to grasp. In the end, they have one very important thing in common: theyâre both wrong. The second step is the collection, enumeration, classification and analysis of data by using appropriate statistical techniques. To be fruitful for enquiry, the assumption must be general. This method is realistic. Image Courtesy : knowledgejump.com/web_pics/examples/Slide30.jpg. It involves detailed and painstaking processes of collection, classification, analyses and interpretation of data on the part of trained and expert investigators and analysts. Following are the major demerits of inductive method; The induction method is also known as the historical, empirical, and posterior method was advocated by economists related to German Historical School. Engel’s Law of Family Expenditure and the Malthusian Theory of Population have been derived from inductive reasoning. Inductive method (Inductive Reasoning) adopts statistical and mathematical methods for getting conclusions regarding economic phenomena. So the hypothesis stands verified. The inductive method makes use of the statistical method. The verification of theories, generalisations or laws in economics is based on observation. On the basis of observation, generalisation is logically derived which establishes a general truth from particular facts. were based on this method. For instance, the generalisations of the classicists were based on inadequate data and their theories were refuted. Once a generalisation is established, it becomes the starting point of future enquiries. However, economics is also an empirical subject, using inductive methods to explain observed facts. It involves abstraction and simplifies a complex problem by dividing it into component parts. Despite these merits, much criticism has been levelled against this method by the Historical School which flourished in Germany. The inductive method is dynamic. Ahuja, H.L. Since economics is concerned with human behaviour, there are problems in making observation and testing a hypothesis. However, a deductive method begins with general theories and principles about economics, generating a hypothesis before testing them, a reverse of inductive methods in economics when discussing theories. Induction helps in future enquiries. Observation 1.1. For instance, the classicists assumed in their reasoning that particular conditions prevailing in England of their times were valid universally. An inference is a logical connection between two statements: the first is called the premise, while the second is called a conclusionand must bear some kind of logical relationship to the premise. It helps to establish a general truth relating to a particular fact. The historical or inductive method expects the economists to be primarily an economic historian who should first collect material, draw generalizations, and verify the conclusions by applying them to subsequent events. For example, identify the missing terms in the given sequence: 1, 1, 2, 3, 5, 8, _, _, _. Inductive reasoning uses specific ideas to reach a broad conclusion, while deductive reasoning uses general ideas to reach a specific conclusion. Inductive reasoning is a type of logical thinking that involves forming generalizations based on experiences, observations, and facts. For example, the hypothesis that firms always attempt to maximise profits, rests upon the observation that some firms do behave in this way. Some of his actions are also bound by the legal and social institutions of the society in which he lives. Due to the complexity of certain economic problems, it becomes difficult to apply this method even at the hands of an expert researcher. Dogs A and B have fleas 1.3. Every hypothesis is based on a set of assumptions. The chief defect of the deductive method “lies in the fact that those who follow this method may be absorbed in the framing of intellectual toys and the real world may be forgotten in the intellectual gymnastics and mathematical treatment.”. Jhingan, M.L (2012). This premise is based on a priori knowledge which will continue to be accepted so long as conclusions deduced from it are consistent with the facts. In reality collection of data is not enlightening unless it is related to a hypothesis. (6) Controlled Experimentation not Possible in Economics: Besides the statistical method, the other method used in induction is of controlled experimentation. The deductive method helps in drawing inferences which are of universal validity because they are based on general principles, such as the law of diminishing returns. It is also described as a method where one's experiences and observations, including what are learned from others, are synthesized to come up with a general truth. Furthermore, economists study the economic phenomenon in which pressure groups such as employer’s associations, trade unions, farming lobbies, political parties with their different ideologies play a crucial part and their activities render it difficult to make controlled observation and experimentation on the economic world. In this, changing economic phenomena can be analysed on the basis of experiences, conclusions can be drawn, and appropriate remedial measures can be taken. By its nature, the inductive method allows to be more flexible and lends itself to the exploration, mainly at the beginning. This method is dynamic. Thus, statistical techniques lack concreteness. Thus statistical techniques may lack correctness. Reasoning is the process of using existing knowledge to draw conclusions, make predictions, or construct explanations. The historical or inductive method expects the economist to be primarily an economic historian who should first collect material, draw gereralisations, and verify the conclusions by applying them to subsequent events. Definitions, sources, and methods used in statistical analysis differ from investigator to investigator even for the same problem. In the induction method, statistical use is essential and it is required while generalizing the hypothesis of theory from particular to general structure. And right observation depends upon data which must be correct and adequate. or narrow relating to an industry. (4) Verifying the hypothesis. When economic analysis is conducted through deductive method, the economic analyst has to proceed from general to particular. Further, the hypothetical conditions are so chosen as to make the problem very simple, and then inferences are deduced from them. By discovering and providing general principles, induction helps future investigations. Content Filtrations 6. For instance, India and America differ in their factor endowments. The inductive method involves the following steps: In order to arrive at a generalisation concerning an economic phenomenon, the problem should be properly selected and clearly stated. Inductions, specifically, are inferences based on reasonable probability. Prof. Lerner, therefore, points out that the deductive method is simply “armchair analysis” which cannot be regarded as universal. This method is dynamic. Thus induction is the process in which we arrive at a generalisation on the basis of particular observed facts. to research, a researcher begins by collecting data that is relevant to his or her topic of interest. The collection of detailed data and the use of statistical methods to arrive at economic generalization describing the relationship between facts are being increasingly made. It is the technique of a practical approach to the problem of economic science. An economist recognized such a problem and collected detailed data from the number of farmers. It involves the process of reasoning from certain laws or principles, which are assumed to be true, to the analysis of facts. Thus the downward sloping demand curve, for example, can be deduced from general assumptions about how people try to maximise their satisfaction from the purchase of goods and services. Thus, the inductive method has the merit of applying generalisations only to related situations or phenomena. 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. Inductive method is advantageous in inspecting the changing phenomena of economics. This method of analysis is based on the assumption that economic conditions remain constant. It means if the prediction made by hypotheses is agreed with the fact then the generalized result is produced and established as law or theory. Deductive and Inductive Methods of Economics (Merits and Demerits) The Deductive Method In inductive reasoning, we begin with specific observations and measures to arrive at some general conclusions. Inductive reasoning begins with a small observation, that determines the pattern and develops a theory by working on related issues and establish the hypothesis. The use of deductive method is indispensable in sciences like economics where experimentation is not possible. It is also called empirical, historical, and a posterior method derives economic generalizations based on experience and observations. The inductive method involves the following steps; To arrive at a generalization concerning an economic phenomenon, the problem should be properly selected and clearly stated. Mill characterised it as a priori method, while others called it abstract and analytical. Statistical Induction. A generalization drawn under the inductive method is often historic-relative in economics. Develop a theory 3.1. These steps are discussed as under. Inductive Reasoning: The first lipstick I pulled from my bag is red. Advanced Economic Theory. Inductive reasoning is a method of reasoning in which the premises are viewed as supplying some evidence, but not full assurance, of the truth of the conclusion. All observed animals depend on water to exist 3. Bacon described it as an ascending process in which facts are collected; arranged and then general conclusions are drawn. A low-cost airline flight is delayed 1.2. A hypothesis is true or not can be verified by observation and experiment. The âdeductive methodâ reasons from generalizations to particular instances. Definitions, sources and methods used in statistical analysis differ from investigator to investigator even for the same problem, as for instance in the case of national income accounts. Report a Violation, Scientific Theory: The Nature of Scientific Theory in Economics, Methods of Economic Analysis: Deductive Method and Inductive Method, Functions of Economies: Production, Consumption and Growth. Thus, the scope for controlled experiments in inductive economics is very little. It may be very wide like poverty, unemployment, inflation, etc. So deduction depends upon the nature of assumptions. (2) The formulation of assumptions on the basis of which the problem is to be explored. Then, the same activity is performed with another triangle, and the result is the same, 180º. There are two method of reasoning in theoretical economics. This aids noteworthy improvements in the application of induction for analyzing economic problems of a wide range. If the premise is true, then the conclusion is probably true as well. Often the conclusions derived from deductive reasoning are not applicable universally because the premises from which they are deduced may not hold good at all time and places. In this method detailed data are collected with regard to a certain economic phenomenon and effort is then made to arrive at certain generalisations which follow from the observations collected. Therefore, induction is the process of arriving at a generalization based on a particular observed fact. First, the internal angles of a triangle are added and it is noted that they result in 180º. Prohibited Content 3. A) Development of a story from a given outline is an example of inductive method because the student may develop any story from the given outline (specific) based on his/her imagination. Researchers make hypotheses and explain some results based on general rules but often need to make new general theories to explain specific results that do not fit into the existing theoretical framework. But other things seldom remain the same which tend to refute theories. The two methods are 1. As pointed out by Cairnes, The method of deduction is incomparably, when conducted under proper checks, the most powerful instrument of discovery ever wielded by human intelligence. In this method, problems are identified and defined, information relevant to the problem are collected, organised and analysed, leading to the establishment of an economic theory. This is in contrast to deductive inferences, in which the conclusion must be true if the premise is. Further, economic phenomena are very complex as they relate to man who does not act rationally. (3) The formulation of hypothesis through the process of logical reasoning whereby inferences are drawn. However, the inductive method is not without its weaknesses which are discussed below. The problem which an investigator selects for enquiry must be stated clearly. Let us discuss the importance of these two methods. Inductive Approaches and Some Examples. This aids noteworthy improvements in the application of induction for analyzing economic problems of a wide range. This method is extremely useful in natural and physical sciences which deal with matter. The inductive approach consists of three stages: 1. Further, the use of the mathematical-deductive method helps in revealing inconsistencies in economic analysis. As pointed out by Gide and Rist, “In a science like political economy, where experiment is practically impossible, abstraction and analysis afford the only means of escape from those other influences which complicate the problem so much.”. The inductive method was employed in economics by the German Historical School which sought to develop economics wholly from historical research. This type of reasoning flows from facts to theory. DEDUCTIVE, INDUCTIVE, AND ABDUCTIVE REASONING. He observed the problem set the hypothesis and through testing and applying against real-world data arrived at the generalization that is known as the law of diminishing returns. In particular, the collection of data by governmental and private agencies or macro variables, like national income, general prices, consumption, saving, total employment, etc., has increased the value of this method and helped governments to formulate economic policies pertaining to the removal of poverty, inequalities, underdevelopment, etc. The inductive method was strongly advocated by economists belonging to the German Historical School. They are the deductive and inductive methods. Disclaimer 9. In this method changing economic phenomena can be analyzed based on experiences, conclusions can be drawn and appropriate remedial measures can be taken. Examples of Inductive Reasoning. Deductive Methods and 2. The conclusion drawn from insufficient data may create greater risk. For this, it uses statistical methods. Marshall also supported the complementary nature of the two methods when he quoted Schmoller: “Induction and deduction are both needed for scientific thought as the right and left foot are needed for walking.” And then Marshall stressed the need and use of integrating these methods. The inductive method is not only time-consuming but also costly. As a matter of fact, deduction and induction are the two forms of logic that help to establish the truth. A simple example is to find out the result of the sum of the internal angles of a triangle. Economic relationships are of less uniform patter in comparison with natural science. Induction relies on statistical numbers for analysis that can be measured and misrepresented when the assumptions which are required for their use are forgotten. Observe a pattern 2.1. But unlike the natural sciences, there is little scope for experimentation in economics because economics deals with human behaviour which differs from person to person and from place to place. Inductive approach, also known in inductive reasoning, starts with the observations and theories are proposed towards the end of the research process as a result of observations.. Inductive research âinvolves the search for pattern from observation and the development of explanations â theories â for those patterns through series of hypothesesâ. Inductive Methods. Induction is actual and synthetic because it deals with the subject as a whole and does not divide it into parts artificially. Thus induction ensures from time to time new problems to pure theory for their solution. This method is however a complicated, time consuming, and expensive method of lawmaking. However, it needs to be emphasized again that the use of induction or empirical method is not of much value if it is not supported by the economic theory or hypothesis established by the deductive method. Moreover, controlled experiments in a laboratory are not possible in economics. In an inductive approach Collect data, analyze patterns in the data, and then theorize from the data. Based on generalized theories or thoughts hypotheses are formulated for predicting the values of parameters considered in the problem. Much research in fields as diverse as economics, physics, and biology make use of both deductive and inductive reasoning. It involves a detailed and painstaking process of collection, classification, analysis, and interpretation of data on the part of trained and expert investigators and analysts. Bacon described deduction as a “descending process” in which we proceed from a general principle to its consequences. The mathematically trained economist is able to deduce inferences in a short time and make analogies with other generalisations and theories. More so, when he uses mathematics or econometrics. These two methods are very different and offer different elements when carrying out an investigation. 4. New Delhi: S Chand And Company Limited. The collected data are used to observe particular facts concerning our problem. Now-a-days, economists are combining induction and deduction in their studies of economic phenomena in various fields for arriving at generalisations from observed facts and for the indirect verification of hypotheses. Since it is drawn from a particular historical situation, it cannot be applied to all situations unless they are exactly similar. (4) Testing and Verifying the Hypothesis: The final step in the deductive method is to test and verify the hypothesis. The Engel’s Law of Family Expenditure and the Malthusian Theory of Population have been derived from inductive reasoning. The inductive method which is also called empirical method derives economic generalisations on the basis of experience and observations. The inductive method refers to the process of reasoning from part to the whole, from specific to general, from narrow to wider, from individual to the universe. For example, an economist who asks if a government program of public works spending will stimulate a regionâs economy will proceed to research the issue, collect and analyze data, and based on conclusions⦠Three methods of reasoning are the deductive, inductive, and abductive ⦠This supposition was wrong. Above video describes you The Methods used to Study Economics. Inductive and Deductive Methods: 1) Deductive Method: The deductive method is also known as the abstract or analytical method. Thus induction method has the merit of applying generalizations only to related situations or phenomena. basically there are 2 methods - 1. ADVERTISEMENTS: Thus the downward sloping demand curve, for example, can be deduced from general assumptions about how people try to maximise their satisfaction from the purchase of goods and services. In contrast, deductive reasoning begins with a general statement, i.e. Copyright 10. The idea here is to remove or reduce the gap between theory and practice. The best example of inductive reasoning in economics is the formulation of the generalisation of diminishing returns. Data are used to make observation about particular facts concerning the problem. Privacy Policy 8. In reality, collection of data is not illuminating unless it is related to a hypothesis. Another 20 flights from low-cost airlines are delayed 2.2. Employers look for employees with inductive reasoning skills. In any economic enquiry, more than one set of assumptions should be made in terms of which a hypothesis may be formulated. The best example of inductive reasoning in economics is the formulation of the generalization of diminishing returns. The next step is to formulate a hypothesis on the basis of logical reasoning whereby conclusions are drawn from the propositions. Examples of the inductive method. Thus, induction suggests new problems to pure theory for their solution from time to time. (2017). Inductive Method.
