How Do We Pay for It?

Exploring the transition to a degrowth economy often leads to the pivotal question: "How do we pay for it?" This page delves into Modern Monetary Theory (MMT) as a lens through which to view the financing of degrowth initiatives. By breaking down MMT, we'll uncover how this economic framework can support the necessary shifts towards sustainability and equity, challenging conventional views on public financing and monetary policy.

What is Modern Monetary Theory?

At its heart, Modern Monetary Theory (MMT) offers a fresh lens through which we can view our economy and the role of government spending. Unlike traditional economic theories that often compare a country's budget to a household's—emphasising the need to balance income (taxes) and expenses (government spending)—MMT presents a different perspective, particularly for countries that issue their own currency, like the US, Mexico, Australia, and China.

Key Insights from MMT:

Sovereign Currency: MMT emphasises that countries which control their own currency can never "run out of money" in the same way businesses or individuals can. They can always create (print) money to fund public services and initiatives.

Inflation Over Debt: Because governments that issue their own currency can never run out of money, MMT suggests focusing on inflation instead of worrying about accumulating debt. If a government spends more money than the economy can absorb without a corresponding increase in labour, goods and services, it could lead to inflation. Therefore, the real limit to government spending is not debt but the economy's capacity to absorb that spending without causing too much inflation.

The Role of Taxes: MMT shows us that governments don't need taxes to fund spending directly. Instead, they serve to control inflation, redistribute wealth, and encourage or discourage certain behaviours (like taxes on tobacco). This shifts the conversation from "How will we pay for it?" to "How do we manage the economy's resources efficiently?"

Unemployment: MMT views unemployment as evidence that there's more capacity for government spending on productive projects without causing inflation. It proposes the idea of a Job Guarantee to provide employment to everyone willing and able to work, thereby achieving full employment and stabilising the economy.

In essence, imagine the economy as a sink, where the water level represents the total money in the economy. Government spending is like the faucet/tap, adding water (money) into the economy, while taxes are the drain, removing some of it. MMT suggests that the goal is to adjust the flow carefully using the 'sink stopper' (tax policy) to keep the "sink" adequately filled without overflowing (causing inflation) or running too low (causing unemployment).

Why is MMT Relevant to Degrowth?

MMT offers a key to unlocking a successful degrowth transformation by showing us that governments can afford to invest in a healthier planet and society without needing the economy to grow. MMT teaches us that a country with its own currency can fund big changes for the environment (ecosystem regeneration, renewable energy deployment, convivial conservation) and communities (job guarantee, universal basic services, community resilience) as long as it keeps an eye on not causing too much inflation. This means we can focus on what truly matters—building a sustainable world with less waste and more care for people and nature. By embracing MMT, we can pave the way for degrowth, shifting resources towards things that make life better for everyone without pressure to constantly increase economic output (GDP).

This accessible academic paper is a fantastic overview of how we can completely change our economy to get back within planetary boundaries by using insights from Modern Monetary Theory.
