of vehicles of 4,500 pounds, is very popular in the United States. Negative externalities can be corrected with some help from the government, Wolla says.A typical example of negative externalities is the sport utility vehicles (SUVs). In a December 2020 Regional Economist article, economist and Research Officer Guillaume Vandenbroucke explains that a “lack of social distancing by one person during the pandemic creates an externality: a higher risk of infection for all.” He further explains that understanding externalities helps us understand the policy debate surrounding the COVID-19 pandemic and government’s role in externalities. What Does a Pandemic Have to Do with Externalities? People can enjoy the benefits-a warning system or a nice view-without encountering a cost. Other positive externalities are generated by a neighbor’s puppy that only barks at strangers and a neighbor’s lawn that’s beautifully landscaped. “In addition, more education leads to higher worker productivity and higher living standards for society in general.” “For example, well-educated citizens are more likely to make good decisions when electing leaders,” he says. In his video, Wolla explains how education produces positive externalities: The benefits don’t only go to the person getting the education, but also “spill over to society in general,” Wolla says. Education Generates Positive Externalities We’ll see later that in some circumstances a barking puppy can create a positive externality, however. Other negative externalities occur from a puppy that barks all the time and a radio blaring in the middle of the night-there’s seemingly nothing beneficial about either of those for the neighbors. Instead, if society wants clean air, society must pay to clean it.” “If the firm were paying the full cost of production, it would return clean air to the atmosphere. “In its production process, the firm uses clean air-a resource it does not pay for-and returns polluted air to the atmosphere, which creates a potential health risk to anyone who breathes it,” Wolla explains. Thus, the factory is shifting some of the production costs to society. Even those who don’t buy any widgets breathe the polluted air. Wolla talks about a factory that produces widgets and has smokestacks that belch out pollution 24/7. In the Economic Lowdown series video “Externalities,” Scott Wolla explains what makes pollution a negative externality. What Makes Pollution a Negative Externality? Let’s dig into the details and look at some examples. Not all goods and services come with externalities, but many do-and some that do might be a surprise.Externalities that provide a benefit to others are “positive externalities.” Education, for example, generates positive externalities. Pollution is an example of a negative externality. Externalities that place a cost on someone, on a community or on society as whole are known as “negative externalities.” Put another way, a negative externality happens when a cost, or burden, “spills over” to a third party.Pandemics, pollution and puppies, as well as education and well-manicured lawns, help explain the economic concept of externalities.įrom an economic perspective, externalities are costs and benefits that impact someone other than the producer or the consumer of a good or a service. But what does a pandemic have in common with pollution-or puppies? A lot of attention has been given lately to wearing masks and social distancing since we are, after all, in the midst of a pandemic.
