Generally, there are two common methods that we can use to check if the PPP holds: the unit root test and cointegration test. The first method is the unit root tests which is to check the stationary or non-stationary of the real exchange rate. If it is stationary, it means the PPP will hold; if it is non-stationary, the PPP does not hold. Another method is cointegration test that can be used to test the residuals, this method can help to avoid wrong regression results. (Charles Engel (1998) & Douglas G. Steigerwald (1996)) The problems with PPP: As many economists concluded, the PPP cannot hold in practice due to there are five main problems behind PPP. In this part, I will explain each one of them in detail. Frist problem is statistical. …show more content…
M. Suranovic, 1999). Since the Law of on price concept is underlying the PPP, both of the theories have the same assumptions. In the previous part, I mentioned the assumptions underlying the law of one price is assume there is no transportation costs and other barriers to trade between the markets which can be implied as there are no trade restrictions in those markets. Despite that, those types of costs and trade restrictions exist in real world, as the transport cost increase, the movement of the exchange rate can be greater and the price of any identical goods can be more expensive. For example, there is a graph from Mohammed and Jeffrey‘s (2004) paper shows the deflated by Jute price are fell faster than the index deflated by Sauerbeck. This means the long distance transport costs fell sharply during the 19th century, and the reason could be the difference between the different routes become less and as well as the price of …show more content…
According to PPP or Law of on prices, if convert the price of a basket of goods in one currency into another currency, the price should be same. But in the real world, when an identical basket of traded and non-traded goods are converted to a common currency, the price index tend to be higher in richer countries. For instance, one dollar can buy more goods in Mexico than in the US. Because of this problem, a modification model is introduced by Balassa (1964) and Samuelson (1964) which are aims to amend the PPP. The Balassa Samuelson model indicates that due to the lower productivity of traded goods sector in developing countries, the price of non-traded goods is lower. That is, the low productivity in tradable sector lead to cheap labors which means the price in non- tradable sector are low. In addition, the Balassa Samuelson effect suggested that the higher income for each capital, the higher the relative price of non-traded goods. As Kenneth (1996) mentioned in his paper, the relationship between the country income and prices is
He then, states that the number of jobs lost barely even put a dent in the number of jobs produced by trade. Another important issue of the trade system is that the people who get rich from trade, keep getting richer while the poor stay poor. This is partially solved by protectionism (taxing imports), although it slows economic growth in the long run and protects some of the jobs that would be lost in the short run. To help understand the price of trade barriers, he explains this by stopping trade across the Mississippi River. This shows that the east side would then have to stop producing their goods and spend some of their time producing what the west side used to export. Although, there would be an increase in jobs, it would not be efficient because they are not using specialization to their full advantage. The author then moves on to the point that trade lowers the price of goods, due to it being cheaper to produce in other areas. He portrays this by showing why Nike can produce shoes in Vietnam instead of the United States. He further elaborates his point by proving that trade helps poor countries as
...lict. Neighboring countries will want to maximize their own revenues and in order to do so, they will set their own prices for goods and services.
The Mc Donald Big Mac index, also known as the Big Mac Purchasing Power Parity (PPP) is a periodic survey done by “The Economist” magazine. This index measures the Purchasing Power Parity between nations using the international prices of the burger as a benchmark (R.L.W., 2014). The index draws its rationality from the concept of “the law if one price”, which infers that in the long-run, all goods must sell for the same price in all locations. This law constitutes the bases of the Purchasing Power Parity theory, which is derived from no arbitrage postulation.

Economic indicators often affect and influence the value of a country's currency. The Trade Deficit, the Gross National Product (GNP), Industrial Production, the Unemployment Rate, and Business Inventories are examples of economic indicators. We will be dealing with four specific indicators: interest rate, inflation, unemployment, and employment growth, as well as Real Gross Domestic Product (GDP). Real GDP is so called because the effects of inflation and depreciation are accounted for in the figures. The state of the economy is important both on a micro and macroeconomic level.
To calculate the change in his purchasing power (CPP) we can use the following formula:

Affordable health care law or Patient Protection and Affordable Care Act (PPACA) is the novel commandment that touches the practice of public health or community health nursing. PPACA, also known as the Affordable Care Act, (ACA) is a united State federal decree signed into law by President Barack Obama on March 23, 2010. The ACA proposal emphasizes three foremost approaches: 1). Dropping costs and increasing productivity so the organization works. 2). Proposing inexpensive, manageable coverage for everybody. 3). Accentuating deterrence agendas in the public health setting (Anderson, K. 2009).
The immigration of Mexicans and Puerto Ricans has brought tremendous talent and great people. However, in the process, the culture of Mexicans and Puerto Ricans are slowly diminishing. The idea of jobs being readily available for immigrants has deprived the culture and saturated the perception of Latin Americans as workaholics. The essays I chose were Puro Border and the Puerto Rican Obituary. Both essays have given context of how Puerto Ricans and Mexicans are slowly losing their identity in this great America. Also in this essay I will be explaining how material wealth can cause the border to become a vacuum.

In order for international trade to work well, governments must allow the world market to determine how goods are sold, manufactured and traded for all to economically prosper. While all nations may have the capability to produce any goods or services needed by their population, it is not possible for all nations to have a comparative advantage for producing a good due to natural resources of the country or other available resources needed to produce a good or service. The example of trading among states comprising the United States is an example of how free trade works best without the interve...

The example used above (which demonstrates increasing opportunity costs, with a curve concave to the origin) is the most common form of PPF. It represents a disparity, in the factor intensities and technologies of the two production sectors. That is, as an economy specializes more and more into one product (such as moving from point B to point D), the opportunity cost of producing that product increases, because we are using more and more resources that are less efficient in producing it. With increasing production of butter, workers from the gun industry will move to it. At first, the least qualified (or most general) gun workers will be transferred into making more butter, and moving these workers has little impact on the opportunity cost of increasing butter production: the loss in gun production will be small. However, the cost of producing successive units of butter will increase as resources that are more and more specialized in gun production are moved into the butter
