Using Interdisciplinary Teaching in Economics
Vision, Academic Leadership, and Interdisciplinary Learning
It is fascinating that many questions of interest to economists are also examined by other disciplines. For instance, political scientists are interested in the impact of trade between countries, and scholars in the field of education investigate what determines the level of schooling people complete. Ecologists and Epidemiologists investigate the impact of environmental degradation on health, although they may not refer to this development as a negative externality.
When Neil Rudenstein was president of Harvard he asked the faculty to envision a University organized around questions rather than departments. He imagined various buildings on campus that would house faculty, regardless of their current departmental affiliation, with common interests such as: the well-being of children, peace, technology and life, or water. He initiated this conversation to emphasize his belief that examining issues from multiple perspectives and integrating insights from across disciplines – interdisciplinary thinking – would lead to a deeper understanding of the issues that we find perplexing. Within this spirit, economic research and instruction is becoming increasingly interdisciplinary.
Why Use Interdisciplinary Teaching in Economics?
The discipline of economics is a behavioral science primarily concerned with the production of goods and services and the allocation of scarce resources to promote social welfare. Economists typically examine questions that are also being investigated in other disciplines, but with different analytical frameworks and methodologies. Thus an interdisciplinary approach that fuses knowledge and insights from other disciplines with an economic framework of analysis to form a more inclusive means of examining questions will foster a richer, more productive, discourse.
Some examples where an interdisciplinary perspective might be useful in exploring issues of interest to economists would include efforts to understand the causes and consequences of; joblessness, pollution, educational attainment, and health care. All of these issues have psychological, sociological, moral, and political dimensions for which a market framework may not be sufficient means of exploration.
Thinking Like an Economist is Becoming More Interdisciplinary
Economics Teaching is Now More Interdisciplinary
Colander and McGoldrick (2010) prepared a book for the Teagle Foundation on the status of the economics major and its contribution to the liberal education of students – the accumulation of broad knowledge, transferable skills, and a passion for learning. They assert that economics courses should help students develop their capacity to think critically, integrate insights from the full range of courses they have taken across the curriculum, explore "big think" questions, and account for moral and ethical dimensions of issues – the fundamental features of interdisciplinary learning.
Economic Research is Now More InterdisciplinaryA number of economic research studies are now drawing on insights from other disciplines to inform their efforts to understand a wide range of questions. This development suggests that in the research sphere, economists believe the gains of interdisciplinary evaluation are greater than the costs. A number of examples will serve to illuminate the breadth of interdisciplinary research that economists are engaged in, and serve as a signal that economics instruction benefits from the integration of ideas from other disciplines, and the gains likely supersede the costs.
- Biology, Sociology, and Economics
- Bedhard and Dhuey (2006) use insights from biology and sociology in their work asking at what age should a child start kindergarten
- Their work could be discussed in a course on labor economics when the link between family wealth and schooling is discussed or in courses on poverty, income distribution, or social problems when discussing factors leading to greater income inequality over time.
- Psychology and Economics
- Akerlof (1982) draws on ideas from psychology and sociology in a study that asks how a firm can motivate employees to work hard and reject shirking
- This paper would be illuminating as part of the section in a labor economics class dedicated to understanding ways to reduce worker shirking.
- Neuroscience and Economics
- Berns, Laibson, and Loewenstein (2007) draw on neuroscience scholarship to examine how people make decisions about outcomes today - such as marriage, enrolling in school, saving - and alternative outcomes at a future date.
- A fundamental topic in courses on Finance concerns why some people are savers and others are so myopic. An examination of this work would offer some insights and likely stimulate interesting discussion.
- Religion, Sociology, and Economics
- Krueger, and Maleckova (2003) draw on ideas from the disciplines of religion and sociology to ascertain the factors that lead a person to become a terrorist and engage in a suicide bombing.
- Economics and policy courses that address contemporary social issues as well as courses in international trade and development inevitably discuss factors that inhibit trade and economic well-being. A discussion of this paper would contribute to that dialogue.
- Demography, Sociology, and Economics
- Chiteji and Hamilton (2002) use insights from demographers and sociologists to explain why the racial gap in wealth exists and to challenge the longstanding belief that African American families are less thrifty than comparable white households.
- Courses on the Economics of Race and on Income Inequality cover the causes and consequences of the racial wealth gap. This paper offers a neglected or ignored explanation - intrafamily financial relations and how they may differ across racial groups - that will enrich the classroom discussion
These examples offer a flavor of the types of questions economists are examining in an interdisciplinary manner and reveal that the notions integrated from other disciplines are leading to new insights that would have been undiscovered if a discipline specific approach was adopted.
