Another Currency War Is Brewing on the Horizon

(Updated 07/21/2018) (Bloomberg) The currency war has arrived as the U.S. and China open up a new front in their increasingly acrimonious game of brinkmanship. The repercussions could threaten the global financial order. Supply-and-demand, inflation , interest rate differentials , purchasing power parity , and other economic factors will cause changes to a currency's relative worth. [1,29] For example, a country's currency tends to appreciate under the following conditions: Less accommodative monetary policy  or fiscal austerity [13] by Raising interest rate For example, Fed Chief Paul Volcker hiked interest rates to fight off inflation during the 1970s and early 1980s and subsequently the dollar surged 78% from June 1980 to December 1984. Under the best practices, governments are encouraged to use interest rate tools rather than manipulate the exchange rate.  Slashing budget Stronger economy Recently, the dollar surged to its highest level in nearly s...

Algae are a very large and diverse group of eukaryotic organisms. Most are phototrophic . Given them right conditions, they can grow very fast in most marine environment including swimming pools. To maintain a healthy swimming pool, the main task is to control their growth—the best process is elimination. In this article, we will examine how to clean and test pool water to eliminate algae . Algae Problem Algae spores constantly enter the pool, brought in by wind, rain or even contaminated swimsuits or equipment. When conditions are right, an algae bloom can occur seemingly overnight. These conditions include out of balance water, warm temperatures, sunlight and presence of nitrates , phosphates , and/or carbon dioxide . Of course, a lack of proper circulation, filtration and sanitation may be the primary cause of the algae. There are over 21,000 known varieties of algae!

Social Security: Should You Retire at Age 62?

Image
After taking a look at the "actuarial adjustments" of social security benefits below: you ask yourself: should I retire at age 62 or not? Tradeoffs The Social Security Administration has designed the benefit formula to, on average, yield the same amount in lifetime benefits irrespective of when you begin receiving payments.  Here is how the U.S. Government Accountability Office explained: "The Social Security benefit formula adjusts monthly payments so that someone living to average life expectancy should receive about the same amount of benefits over their lifetime regardless of which age they claim." If you expect to live to average life expectancy (78.74 in 2012), maybe the decision to retire earlier at age 62 or not is irrelevant. In [1], it has suggested that: If you're fortunate enough to live well into your 80s or beyond, then waiting will indeed result in a larger lifetime haul. However, if I were you, I would go with the prevalent wi...

Image
To maintain the health of your pool, there are two main areas to be considered: Chemical Mechanical For the chemical part, you always need to estimate the size of pool first.  For example, if you need to add chlorine shock,  Leslie's Swimming Pool Supplies always ask your pool size in gallons before they decide how much chlorine powder you need for your pool. If your pool has regular shapes such as rectangles or circles, it's relatively easy to come up the pool size.  For example, for a rectangular pool, its size can be estimated by: Average depth * width * length If you measure your three dimension in feet, you will come up total cubic feet of your pool size. Converting Cubic Feet to Gallons To convert cubic feet to gallons, you can use the following formula: 1 ft 3 * 7.48 gallon/ft 3 = 7.48 gallons To simplify, you may use 7.5 instead of 7.48 in you calculation.  If you have an irregular shape, say, kidney shape as shown below, it takes a bit ...
