Saving is setting aside money for emergencies or a future purchase. On the other hand, investing is buying assets such as real estate, stocks, or bonds with the expectation that your investment will grow.<\/p>\n<p>Now, consider the basic economics formula of GDP:<\/p>\n<p>$$GDP = C + I + G + (X \u2013 M)$$<\/p>\n<p>Where:<\/p>\n<p>\\(C =\\) Amount spent by consumers on final goods and services<\/p>\n<p>\\(I =\\) Gross private domestic investment. It consists of business investments in capital goods as well as inventory changes.<\/p>\n<p>\\(G =\\) Government expenditure on finished goods and services.<\/p>\n<p>\\(X =\\) Export.<\/p>\n<p>\\(M =\\) Imports.<\/p>\n<p>This section will have a closer look at some of these variables and how they affect other economic variables.<\/p>\n<h2><strong>Trade Balance<\/strong><\/h2>\n<p>Trade balance refers to the balance that should exist between the trade and capital between a country and the rest of the world. In the above formula, the trade balance of any given country is represented mathematically as \\((X &#8211; M)\\), or exports minus imports.<\/p>\n<p>A country&#8217;s trade balance can be positive if the value of exports exceeds the value of imports.&nbsp; Some of the countries that post positive trade balances include China, Germany, and many oil-exporting countries, the most notable being Saudi Arabia. These countries export goods across the world in exchange for foreign currencies.<\/p>\n<p>Conversely, a country&#8217;s trade balance could be&nbsp;negative if the value of imports exceeds that of exports. France, Canada, Greece, and Israel are among net importers.<\/p>\n<p><!--more--><\/p>\n<h2><strong>Saving and Investment<\/strong><\/h2>\n<p>Saving can be absorbed in three different ways:<\/p>\n<ul type=\"i\">\n<li>it can be absorbed into investment spending (I);<\/li>\n<li>it can be absorbed into financing government deficits (G \u2013 T); and<\/li>\n<li>lastly, it can be absorbed into building up financial claims for or against other economies.<\/li>\n<\/ul>\n<p>For a positive trade balance, \\((X &#8211; M) &gt; 0\\); however, for a trade deficit, \\((X &#8211; M) &lt; 0\\). This implies that domestic saving can be supplemented by inflowing foreign saving; hence overseas economies build up financial claims against the domestic economy. As such, the savings equation can be written as:<\/p>\n<p>$$S = I + (G \u2013T) + (X \u2013 M)$$<\/p>\n<h2><strong>Fiscal Policy<\/strong><\/h2>\n<p>Rearranging the saving function gives us an equation for the fiscal deficit:<\/p>\n<p>$$G \u2013 T = (S \u2013 I) \u2013 (X \u2013 M)$$<\/p>\n<p>Where&nbsp;\\(G \u2013 T\\) represents government spending minus the taxes the government collects.<\/p>\n<p>A fiscal deficit shows that the private sector requires an increment of savings and a reduction of investment. In this case, \\((S \u2013 I) &gt; 0\\). Alternatively, the country might resolve to run a trade deficit with respect to corresponding inflow in foreign saving, such that \\((X \u2013 M) &lt; 0\\).<\/p>\n<blockquote>\n<h3><strong>Question<\/strong><\/h3>\n<p>When aggregate expenditure equals aggregate output, the government\u2019s fiscal deficit is <em>most likely<\/em> equal to:<\/p>\n<p>A. private saving \u2013 Investment \u2013 Net exports.<\/p>\n<p>B. private saving \u2013 Investment + Net exports.<\/p>\n<p>C. investment \u2013 Private saving + Net exports.<\/p>\n<p><strong>Solution<\/strong><\/p>\n<p>The correct answer is <strong>A<\/strong>.<\/p>\n<p>The relationship among saving, investment, fiscal balance, and trade balance can be expressed by the equation \\(G \u2013 T = (S \u2013 I) \u2013 (X \u2013 M)\\). This means that expenditures on investment, net exports, and the government fiscal balance must be funded by private savings.<\/p>\n<\/blockquote>\n<div class=\"notes_inv\"><hr>\n<p><a
