Macroeconomics: imbalances in the balance of payments

  • Current account deficit: 
    • this will cause a currency depreciation, as the demand for imported goods is bigger than the foreign demand for exported goods. This will make it easier for domestic producer to exports their goods as they, the goods, become relatively cheaper on the foreign market.
    • A deficit in the balance of trade implies that the financial account must be positive (remember Xn= S-I). In order to pay for the imported goods, it must be the case that foreign entities own more domestic financial assets. Furthermore, foreign countries will buy domestic government debt.
    • The central bank can try to offset inflation by raising the interest rate which can then attract foreign capital (i.e money). However, in the short term, this will be a monetary contractionary policy.
  • Current account surplus:
    • The domestic currency will appreciate, since foreign demand for exported goods is bigger than the domestic demand for imported goods. Note that domestic savings are then used to finance foreign consumption.
    • Stronger currency implies that people can more easily import foreign goods as they are relatively cheaper.
    • If a nation heavly relies on exports, a strong currency may have an decrease the standard of living of the country's domestic consumers.
  • Methods for correcting imbalance in the balance of payments: 
    • exchange rate intervention: to correct a trade deficit, the government wants to devalue its currency in order to make its export more attractive to foreign consumers. To correct a trade surplus, a government needs to appreciate its currency, in order to make its export more expensive. 
    • Note that naturally, a current account balance, overtime, moves toward 0 (i.e it is balanced). This is due to the exchange rate responding to the difference between the demand for imported and exported goods.
    • Monetary policies: contractionary policies (i.e raise interest rate) aims to appreciate a country's currency whereas an expansionary policy (i.e lowering interest rate) aims to depreciate the domestic currency.
    • Protectionist policies (tariffs, quotas, and subsidies): these policies aims at promoting domestic industries, thereby reducing reliance on imported foreign products. This method is usually implement in order to obtain a trade balance surplus.

Microeconomics: Firms and cost in the short run

In Economics, the term short run refers to a time period where at least one variable of interest does not change . In our case, the short run for a firm is when at least one input  (labor, land, capital) stays fixed. Usually land and capital are considered fixed in the short run.  If an input is fixed during a period time, no matter how much the total product a firm produces, its cost stays the same. This cost is commonly known as fixed cost (FC). Examples of fixed costs: rent, property taxes, loan payments. Labor is often considered to be a part of the  variable cost (VC) . Variable cost can be defined as the cost a firm has control over during the short run. Unlike fixed cost, variable cost increases (decreases) as a firm's total product increases (decreases). Examples of variable costs include: utility bills, wages, raw materials A firm's total cost (TC) is the sum of its variable and fixed costs. As you can see, the fixed cost...

Macroeconomics: equilibrium in the AD/AS model

Real output and price level in the AD/AS model: The short run equilibrium in the AD/AS model, is when the  intersection between the short run aggregate supply curve and the aggregate demand curve determines the level of output and price level.          This short equilibrium output can be compared to the full-employment (i.e long run equilibrium) output by adding the long run aggregate supply curve in the graph.  If the difference between the short run equilibrium output and full employment output is negative than we have a recessionary gap. This could be caused by a decrease in households' consumption, a fall in private investments, or a decrease in government spending. If the difference is positive, we have an inflationary gap, where the short run equilibrium output is bigger than its full employment output. This can be caused by an increase in households expenditures, expansionary fiscal policy, etc... If the gap is zero, this means that t...

Microeconomics: Shift in Supply

We recently talked about the factors that cause a shift in the demand. It is now time to discuss the factors that shift the supply curve which cause the equilibrium price and demand to change. Determinants of Supply: changes in supply are caused by changes in the price of inputs, the number of firms in the market, technology, changes in the price of related goods and services, and changes in expected prices. An increase (decrease) in the price of an input results in less (more) supply as per unit production costs rise (fall). More competition increases supply, and less competition leads to less supply. If a new firm enters the market for good X, then the supply of good X increases. Improvement in technology can result in an increase in the ability of producers to supply their products. For example, the invention of the printing press increased the supply of books. An increase (decrease) in the price of a related good leads to an increase (decrease) in the supply of the other...
