Economic Impact of Tariffs and Net Exports

Value of the US Dollar in Yen

  • This summer, the value of the US dollar became increasingly inexpensive for buyers using Japanese Yen.
    • Example rates: ¥134 to ¥155.

Net Exports

  • Factors influencing US households’ spending overseas:

    • Decrease in overseas spending: Could occur due to economic downturns or increased domestic prices.
    • Increase in overseas spending: Can happen due to favorable exchange rates or lower tariffs.

  • Tariffs and Trade Barriers:

    • Definition: Tariffs are taxes applied to imported goods, which consumers pay.
    • Purpose: Aim to increase net exports by making imports more expensive, thereby shifting Aggregate Demand (AD) to the right.

Impact of a Shrinking Trade Deficit

  • A shrinking trade deficit indicates that net exports are rising, meaning exports exceed imports.
  • Effects:
    • Results in a rightward shift of the Aggregate Demand Curve, potentially raising GDP and price level.
    • However, it can lead to higher prices for consumers due to the increased demand.

Questioning Tariff Effectiveness

  • Despite the imposition of tariffs, the initial impact on trade deficits was modest due to various factors:
    • Retaliatory Tariffs: Other countries, like China, imposed their own tariffs on US goods, counteracting impacts.
    • Dependence on Imports: Many US firms rely on imported materials, leading to increased costs and prices for consumers.
  • Important Point: Tariffs are paid by importing firms (not foreign governments) and are often passed onto consumers, affecting domestic buyers of imported goods.

Tariff Impact on Prices

  • Increased tariffs did not necessarily lead to overall increases in domestic prices.
  • Historical price levels (inflation rates) from 2019 to 2022 reflect this:
    • Prices stayed fairly consistent despite tariff implementation.

Subsidies to Domestic Producers

  • Definition: Subsidies are financial aids to support domestic producers against foreign competition.
  • Example: The Chips and Science Act of 2022 provided $50 billion to US semiconductor firms to reduce imports and support domestic production.

Economic Performance Indicators

  • Decline in GDP: The US economy saw a shrinkage in GDP during 2020, largely due to the pandemic.
  • GDP data from Q1 2020 to Q2 2022 illustrates fluctuating figures amid economic challenges.

Aggregate Demand and Supply Model: Recession Effects

  • A recession leads to real GDP falling below equilibrium, featuring:
    • Leftward shift of the AD curve illustrated with decreased GDP and price levels.

Variables Affecting Personal Consumption Expenditure (PCE)

  • Factors leading to a decline in household spending:
    • Reduced Income: Job losses, fewer work hours, lower wages.
    • Reduced Wealth: Declining home values, stock market losses.
    • Higher Taxes & Interest Rates: Increased costs reduce disposable income and consumption.

Investment and Economic Spending

  • Factors leading to a decrease in business expenditure on capital:
    • Lower profits from declining sales.
    • Higher corporate taxes and interest rates affecting borrowing costs.
    • Economic environment threats: increased regulations, uncertainty in workforce.

Negative Accelerator Effect

  • The Accelerator Effect explains how drops in PCE influence business investment levels:
    • As consumption decreases, firms may reduce capital investments, leading to a further decline in economic activity and Aggregate Demand.

Government Spending Impact

  • Reduced government spending on military and infrastructure can indirectly affect consumption even if it does not include transfer payments like Social Security.
  • Decreased state and local spending also affects overall economic activity.
