Macroeconomics: balance of payments accounts

  • Balance of payment is the sum of three separate accounts and must always be equal to 0 (given no statistical error):
    • Current account: the net flow of funds exchanged for goods and services, and monetary gifts  that flow in and out of a country. This is often used as an indicator for net export.
    • Financial account: also known as the capital account, is the net flow of funds for investment in real assets (direct investments) or financial assets (stocks or bonds) into a nation.
    • Official reserves: in order to balance the two accounts above, a country must have a reserve of foreign money. It measures the net effect of all money flows from the other accounts.
    • If the current account is positive, it must be the case that the sum of the financial account and official reserves is negative.
  • Current account (CA) components:
    • Balance of trade in goods: spending by consumers and firms on imported and exported goods. Exported goods have a positive effect on the current account, whereas imported goods have a negative effect.
    • Balance of trade in services: tourism, banking, transportation, etc... Domestic services bought by foreigners has a positive effect on CA, and foreign services have a negative effect.
    • Income balance: transfer of incomes earned by workers in one country to a foreign nation and vice versa. If part of a worker's income is sent to a relative in a different country, this has a negative effect on the CA.
    • Current transfer balance: transfer payment made by one nation to another, without an exchange of goods or services, or a person sending/receiving money to /from someone in a foreign country.
  • Positive CA is known as a trade surplus, it receives more payments in its current account from the rest of the world than it sends out, and Xn is positive (generally speaking, the last two components are relatively small). 
  • Negative CA is known as a trade deficit. A nation sends more money than it receives. Its net export variable is expected to be negative.
  • Financial account (FA) components:
    • Direct investments: when an entity acquires about 10 percent of company's ownership. If a domestic investors buy 10 percent of foreign company's ownership this has a negative effect on the FA. Positive effect when a foreign company acquires a domestic company.
    • Portfolio investment: just like direct investment but under 10 percent (mostly about stocks and bonds).
    • Other investments: loans made by banks. When a domestic bank lends money abroad this as a negative effect until the loan is payed back.
    • Note that the capital account is not exactly equal to the financial account. It only focuses on payments for capital expenditures/investments.
  • Official reserves account:
    • Foreign exchange reserves: assets of other nations held the domestic central bank. Consists mostly of foreign government bonds and foreign currency.
    • If the flow of money into the country from the current and financial accounts exceeds the flow of money out of the country, the difference is added to the foreign exchange reserves controlled by the central bank.
    • If the sum of the CA and FA accounts is negative, then there is a positive inflow of money (i.e the central bank must sell its foreign reserves in exchange for domestic money).
    • The foreign exchange reserves can be used to influence the exchange rate.
    • Here are the numbers for the U.S foreign exchange reserves

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...

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...

Macroeconomics: multiplier and crowding out effects

Multiplier effect: whenever   any of the components of AD increases, the increase in GDP will be greater than the initial increase in expenditures. The impact on GDP of a particular increase in spending depends on the proportion of the new income that is taken out of the system to the proportion that continues to circulate in the economy. The multiplier effect tells us the impact a particular change in one the components of AD will have on the total income (GDP).  Let k denote the spending multiplier, which is a function of MPC and MPS. The larger the marginal propensity to consume, the larger the spending multiplier. Notice that the larger the MPC, the greater the impact a particular change in the spending variables will have on the nation's GDP. The crowding out effect: If government spending increases without an increase in taxes, the government must borrow funds from the private sector to finance its deficit, thereby increasing the interest rate. This increase in interest ...
