Purchasing Power Parity (PPP)

What is purchasing power?

Purchasing power refers to currency’s value represented by the number of goods and services one can purchase with a single unit of it. The purchasing power of a currency declines due to inflation and increases with deflation.

A currency’s purchasing power can shed light on the economic well-being of a nation. If a unit of one currency can purchase a greater number of goods than a unit of another currency, then the purchasing power of the former is greater than that of the latter.

Consider, for example, the value of one dollar in the year 1950. It is quite evident that the value of a dollar has declined with time due to inflation. Back in 1950, a better standard of living was affordable, with a lesser amount of money than what is needed today to afford the same lifestyle.

Why is purchasing power significant?

The purchasing power of a currency determines various aspects of an economy. The high purchasing power of a currency also increases demand in the economy, as well as boosts the stock prices and investments into the economy.

Decreased purchasing power may also trigger a spike in interest rates. As prices go up in the economy, monetary authorities increase the interest rates to encourage saving rather than spending in the economy. This happens because saving becomes more incentivising than spending due to increased interest rates. With lesser liquidity in the market, money is sucked out, and prices decrease slowly.

What do we mean by purchasing power parity?

The theory of purchasing power parity allows the comparison of the value of different currencies. A currency’s purchasing power can be considered as the best indicator of its relative worth. Purchasing power parity states that a basket of goods must be priced similarly in different countries, considering their exchange rate.

Given the exchange rate of the currencies of two countries, the amount of money required to purchase the same basket of goods should be “at par” in both. Therefore, currencies must follow PPP to ensure that the income level and economic well-being of the respective countries is similar.

For instance, if the exchange rate to convert currency A into currency B is 20, and a shirt costs 40 units of currency A in Country A, then it should cost 800 units of currency B in Country B. 

How is PPP categorised?

PPP can be categorised into two sub-types:

  • Absolute PPP: The basic concept of PPP can also be termed as Absolute PPP. The theory is developed based on the idea that without any trade restriction, goods should cost the same across different countries. This theory ignores various other factors like inflation rate, which may not always be the same across countries.
  • Relative PPP: This is an extension of PPP as it includes inflation rate over the existing concept of Absolute PPP. It states that there exist are correlation between price inflation and currency exchange rates. Exchange rate, along with the inflation rates in both countries provide a more inclusive approach to PPP.

As inflation reduces the purchasing power of a currency, it needs to be adjusted when two currencies are compared.

How is PPP calculated?

The PPP equation can be represented as follows:

Here S0 refers to the spot exchange rate between Currency A and B. If one unit of Currency A is equal to S0 units of currency B, then PPP states that S0 should be equal to the price of a good in Currency B divided by the price of the same good in Currency A.

Therefore, if the spot exchange rate between Pound Sterling and the Australian dollar is 1.82 and one unit of a good costs £50 in the UK, then the same good should cost A$91 in Australia.

How is PPP useful?

PPP can be used to assess the relative economic strength of two nations. If other factors like inflation are accounted for, then through PPP, the fair price at which countries should be exporting can be calculated using the exchange rate.

Also, if two countries have a lot of disparity in their prices, then it should reflect in their exchange rate. PPP can also be used to compare metrics such as wages and GDP across nations, even when the countries do not have the same currency.

PPP gives a real touch to the nominal currency values. It uses real comparison rather than nominal comparison to give a better understanding of the countries. Through PPP, the focus shifts from the amount of money in an economy, to the value of a single unit of that money.

Do all currencies follow PPP?

It is difficult to observe a scenario where PPP is accurately followed. The assumption that exchange rates account for all factors affecting the variation in prices of a good in two different countries does not always hold.

There are many external factors like tariffs, transportation costs and various levies that affect cross border price variations. The imposition of taxes and government policies that are unfavourable towards imports of foreign goods, majorly impact these price differences across countries.

Market inefficiencies like subsidies, monopolies or the formulation of cartels affect the prices of goods in a country. If a country has a higher number of government subsidies in one sector, then the domestic production of that sector would be more competitive than imports. Thus, the price would vary even more in the presence of subsidies.

Similarly, when companies form a cartel or have a monopoly over a good, they can charge as much for a good as they want. This also leads to a price variation across countries and is not accounted for in the exchange rate.

Even though PPP cannot always hold, it is still a useful tool in comparing economies. The World Bank and WTO both use PPP to compare different economic indicators like income levels and the overall level of well-being across countries.

What is an Absolute Advantage? Absolute advantage is one of the key macroeconomic terms, which is based on the principles of Capitalism and is often utilised in international trade-related decisions. Absolute advantage refers to the competence of a company, region or country to produce goods or services in an efficient manner compared to any other economic entity. The efficiency in production can be achieved by: Production of the same quantity of good or services as produced by other entity by utilising fewer amount of resources Production of a higher quantity of good or services as produced by other entity by using the same amount of resources What is the Significance of Absolute Advantage? Different countries or businesses possess a different set of ability owing to their location, soil composition, weather, infrastructure, or human resource skills. When applied in the right direction, various factors may pan out to offer more cost-effectiveness and hence build absolute advantage of the entity in comparison to others.  The absolute advantage remains one of the critical determinants for the choice of the goods or services to be produced. Absolute advantage in a particular area often translates into profitability in the area. The profit margin increases by the achievement of cost efficiency, allowing the entity to ensure higher profitability over the competitors.  For example, let us assume that the US can produce ten high-quality aircrafts utilising a specific amount of resources. China, on the other hand, can build 6 similar quality aircrafts using the same amount of resources. Thus, in the production of an aircraft, the US holds Absolute Advantage Let’s say the US has the ability to manufacture a certain amount of steel using 10 tonnes of iron ore. China, on the other hand, can produce the same quantity of steel using 8 tonnes of iron ore.Here, China here holds Absolute Advantage in the production of steel.  How Countries Build Absolute Advantage? While natural conditions, which include climatic factors, geometry, topography, cannot be altered for achieving absolute advantage, the countries use the underlying factors strategically in their favour. Furthermore, factors of production are focused at by many companies or nations for building absolute advantages.  Some of the strategies for building absolute advantage includes: Development of Technological Competencies- The implementation of innovative or latest technological innovations allows the entities to lower their production cost, facilitating absolute advantage.  Enhancing Skills of Human Resources- The improvement in the cost-efficiency, along with the quality of the products, is targeted through imparting varying skill development programs. Many countries subsidize or aid the apprentice or labour training for enhancing the absolute advantage in trade.  Improving Infrastructure- The infrastructure enhancement in the form of road, telecommunications, ports, etc. can be useful in enhancing the cost-effectiveness across different industries.  What Do We Understand by Comparative Advantage Vs Absolute Advantage? Evaluating the comparative advantage introduces the concept of opportunity cost, which is the deciding factor to determine the production of particular goods or services. Opportunity cost refers to the potential benefits associated with the next best possible alternative which is missed out when one option is chosen over another.  The Absolute advantage simply considers the capability of a business or region to deliver goods or services in the most efficient manner. The Comparative Advantage, however, also takes into account the benefits that are forgone if an entity decides for production of a particular product or services.  Comparative advantage, based on the notion of mutual benefits, is often used in international trade deals. The Comparative advantage has been the major factor driving the outsourcing of services in search of cheap labour.  Understanding through an Example For instance, country A can produce ten televisions with the same amount of resources with which it can make 7 laptops. The opportunity cost per television is 7/10 or 0.7 laptops. Meanwhile, the opportunity cost per laptop is 10/7 or 1.42 television.  It highlights that country A is forsaking the production of 0.7 laptops if it is deciding to manufacture one television. On the other hand, it is missing out the opportunity to manufacture 1.42 televisions for every single laptop manufactured.  Now, say Country B’s opportunity cost for producing a television is 0.5 laptop, and that of producing laptop is 2 televisions. Then, country B will have a comparative advantage in making televisions, and country A will have comparative advantage in producing laptops. It has to be noted that despite country A having absolute advantages in both the products, it would be mutually beneficial for both the countries if country B produces television while country A produces laptops. Do You Know About Absolute Advantage Theory by Adam Smith? The concept of Absolute Advantage was indicated by Adam Smith in his book called ‘Wealth of Nations’ which focusses on International trade theory. Adam Smith, in his book attacked on the previous mercantilism theory, which mainly stressed for economies to maintain trade surplus in order to command power.  The Absolute Advantage theory considered that the countries possess different ability with respect to the production of varying goods or services. It argued that it is not necessary that a state may hold an absolute advantage in the production of all goods, and here the relevance of trade comes into play.  It advocates that countries should produce those goods over which they hold a competitive advantage. It would allow the countries to make the same amount of goods using few resources or in less time. The theory propagates the relevance of trade for economic sustainability.  What Are the Limitations of the Absolute Advantage Theory? The assumptions used in the Absolute Advantage Theory by Adam Smith may limit the application in real bilateral trade. The limitations of the theory by Adam Smith include: Smith assumed that the productive capabilities of a country could not be transferred between the two countries. However, in practical terms, the competitive scenario aids the nations to acquire new capabilities and acquire new resources, especially in the technological and human resource skill aspects.  The two-country trade which was used as a basis for the theory does not consider the trade barriers levied. The present scenario, however, is strikingly dominated by trade wars between economies. Nations impose huge tariffs, import duties and other type of barriers to promote local manufacturers.  Absolute Advantage theory assumes that the trade between the two nations will take place only if each of the two economies holds an absolute advantage in one of the commodities traded. However, in general, countries despite not holding absolute advantage are engrossed in international trade, boosting their economic setup.

What is accounts payable? Accounts Payable (AP) is an obligation that an individual or a company has to fulfill for purchasing goods and services bought from their suppliers and vendors. AP refers to the amount that is not paid upfront and can be paid back in a short period of time. Hence, a good or a service purchased on credit to be paid in a short period will fall under AP. For individuals, AP may include the bill paid after availing services such as television network, electricity, internet connection, or telephone. Most of the time, the bill is generated after the designated billing period, depending upon the amount of consumption. The customers have to pay this obligation within a stipulated time to avoid default. What is accounts payable from a Company’s point of View? AP is the amount of money a company is liable to pay to its suppliers or vendors and clear dues for purchases of goods and services purchased from its suppliers or vendors. AP is required to be repaid in a short period, depending on the relationship with suppliers. It is essentially a kind of short-term debt, which is necessary to honour to prevent default. As the current liabilities of the company, AP is required to be settled over the next twelve months. It is presented in the balance sheet as the account payable balance. For example, Entity A buys goods from Entity B for US$400,000.00 on Credit. Entity A has to pay back this amount within 60 days. Entity A will record US$400,000.00 as AP while Entity B will record the same amount as Account receivable. AP is also a part of the cash flow statement. The change in the total AP over a period is shown in the cash flow statement, hence it is part of the company’s working capital. It is widely used in analysing the cash flow of the business and cash flow trends over a period. AP may also depict the bargaining power of the company with its vendor and suppliers. A vendor or supplier may give the customer a longer credit period to settle the cash compared to other customers. The customer here is the company, which will incur AP after buying goods on credit from the vendor. There could be many reasons why the vendor is providing a more extended credit period to the firm such as long-term relationship, bargaining power of the firm, strategic needs of the vendor, the scale of goods or services. By maintaining a more extended repayment period to supplier and shorter cash realisation period from the customer, the company would be able to improve the working capital cycle and need funds to support the business-as-usual. However, prudent working capital management calls for not overtly stretching the payable days as it might lead to dissatisfaction of supplier. Also, investors tend to closely watch the payable days cycle to determine the financial health of the business. When the financial conditions of a firm deteriorate, the management tends to delay the payment to their suppliers. Why accounts payable is an important part of Balance sheet and Cash Flow Statement? As inferred from the previous paragraphs, AP is part of the current liabilities of the balance sheet. This is an obligatory debt that has to be paid back within a time frame so that the company does not default. AP primarily consists of payments to be made to suppliers. If AP keeps on increasing over a period of time, it can be said that the company is purchasing goods or services on credit more, instead of paying up front. If AP decreases, it means the company is reducing its previous debts more than it is buying goods on credit. Managing AP is essential to have a stable cash flow. In a cash flow statement prepared through an indirect method, the net difference in AP is shown under cash flow from operating activities. The business entity can use AP to create the desired variation in the cash flow to some extent. For example, to increase cash reserves, management can increase the duration of paying back the credit taken for a certain period, thus affecting the net difference in AP. What Is the Role of Accounts Payable Department? Every company has an accounts payable department and the size and structure depend upon how big or small the enterprise is. The AP department is formed based on the estimated number of suppliers, vendors, and service providers the company is expected to interact with; the amount of payment volume that would be processed in a given period of time; and the nature of reports that a management will require. For example, a tiny firm with a low volume of purchase transactions may require a simple or a basic accounts payable process.  However, a medium or a large enterprise may have a accounts payable department that may require a set of practices to be followed before paying back the credit. What is the Accounts Payable Process? Guidelines or a process is important as it provides transparency and smoothness in facilitating the volume of transactions in any time period.  The process involves: Bill receipt: when goods were bought, a bill records the quantity of goods received and the amount that needs to be paid to the vendors. Assessing the bill details: to ensure that the bill or invoice copy includes the name of the vendor, authorization, date of the purchase made and to verify the requirements regarding the purchase order. Updating book of records after the bill is collected: Ledger accounts need to be revised on the basis of bills received. The department makes an expense entry after taking approval from management. Timely payment processing: the department takes care of all payments that need to be processed on or before their due date as mentioned on a bill. The department prepares and verifies all the required documents. All details entered on the cheque along with bank account details of the vendor, payment vouchers, the purchase order, and the original bill and purchase order are scrutinized. The department also takes care of the safety of the company’s cash and assets and prevents: reimbursing a fake invoice reimbursing an incorrect invoice making double payment of the same vendor invoice Apart from making supplier payments, AP departments also takes care of travel expenses, making internal payments, maintaining records of vendor payments, and reducing costs Business Travel Expenses: Bigger entities or firms whose business nature requires all personnel to travel, have their AP department manage their travel costs. The AP department manages the personnel’s travel by making advance payments to travel companies including airlines and car rentals and making hotel reservations. An account payable department may also deals with requests and fund distribution to cover travel costs. After business travel, AP may also be responsible for settling funds supplied versus actual funds spent. Internal Payments: The Accounts Payable department takes care of internal reimbursement payments distribution, controlling and petty cash controlling and administering, and controlling sales tax exemption certificates distribution. Internal reimbursement payments include receipts or both substantiate reimbursement requests. Petty cash controlling and administering includes petty expenses such as out-of-pocket office supplies or miscellaneous postage, company meeting lunch. Sales tax exemption certificates comprise AP department handling sales tax exemption certificates supply to managers to make sure qualifying business purchases excludes sales tax expense. Maintaining Records of Vendor Payments: Accounts Payable maintains information of vendor contact, terms of payment and information of Internal Revenue Service W-9 either manually or on a computer database. The AP department lets management know through reports on how much the business owes at present. Other Functions: The accounts payable department is also responsible to lessen costs by identifying cost structures and creating strategies to reduce the spending of business money. For example, minimising cost by making payment of the invoice within a discount period. The AP department also acts as a direct point of contact between an entity and the vendor. How to Calculate Accounts Payable in Financial Modelling Financial modelling enables calculating the average number of days a company takes to make bill payments. AP days can be calculated using the following formula: AP value can be calculated using the following formula: What is accounts payable turnover ratio? AP turnover ratio shows the capability of a firm to pay cash to its customer after credit purchases. It is counted as an essential ratio to analyse the cash management attribute of the firm and its relationship with vendors or suppliers. It is calculated by dividing purchases by average AP. Purchases by the company are calculated as the sum of the cost of sales and net inventory in a given period: Now let’s understand this with the help of an example. Let us suppose, Cost of sales of Company XYZ for the period was $60,000, and XYZ began with inventories worth $21000 and ended at $15000. AP at the beginning was $20000, and $15000 at the end. Now the purchases will be $66000 (60000+21000-15000). The average AP will be $17500. Therefore, the AP turnover ratio will be 3.77x. Dividing the number of weeks in a year by the AP turnover ratio will give the number of weeks the company takes on average to settle its payables. In this case, it will be around 13.8 weeks (52/3.77). What is the difference between Accounts Payable vs. Trade Payables? Though the phrases "accounts payable" and "trade payables" are used interchangeably, the phrases have slight differences. Trade payables is the cash that a company is obligated to pay to its vendors for goods and supplies which are part of the inventory. Accounts payable include all of the short-term debts or obligations of a company.

What is the Dark Web?  The dark web is one such portion of the World Wide Web which is not accessible by regular search engines. The dark web is considered a hotbed for criminal activities, and it is much more than that. Various websites exist on an encrypted network inside the dark web. Standard web browsers and programs cannot find these websites. Once inside the dark web, different sites and pages can be accessed like one does on the web. Scientists believe that the internet we see is only 4% of the entire ocean of the web, meaning the 96% consists of the "Deep and Dark Web".  The user interface used in the dark web is usually internet-based, but it utilises special software which is not part of the standard ones. There are dozens of web browsers to surf the internet, but they all work in the same way. These standard browsers use ports and protocols to request, transfer and view data on the Internet. The website you access may look familiar, but as you enter, it may be illegal or something familiar but otherwise not monitored by anyone else. Therefore, the deep web and the dark web are famous for being anonymous. Also read: Cyber Espionage Campaign: Strings that tie China, Australia and the US How to access dark web browser? In order to access a few areas which are restricted, the user may need a password and a process to follow. A special software called TOR (The Onion Router) or the Freenet has these non-standard connections. These browsers are unlike standard internet browsers and have a process to access. They allow the users to browse around the dark web and are focused on keeping the user identity anonymous. If hacked or accessed, the regular web browser can easily provide user information such as who the user is and whereabouts. Though the dark web is providing 100% anonymity, federal agencies have been successful in tracking down criminal activities on the dark web. It is often said that the person you are talking to on the dark web could either be an FBI agent or a criminal. Image: Kalkine   What happens inside the world of the dark web?  The dark web is famous for allowing sinister activities, but many users go on the dark web to access information which otherwise may not be accessible on standard internet. Such as users from extremely oppressive governments who cut access to the world for their citizens. Unfortunately, such confidential environments also provide open platforms to criminals, terrorists and other such individuals involved in illegal activities.   Hence, experts advise users to not access the dark web even out of curiosity as it is a lawless environment. There have been many incidents where innocent, curious users were trapped and forced to get involved in criminal activities or their digital devices hacked and compromised without their knowledge.  A study conducted by a University of Surrey researcher Dr Michael McGuires in 2019, Into the Web of Profit, shows that the dark web has become worse in recent times. Since 2016 of all the listings on the dark web suggested, 60% could harm companies. Everything illegal and criminal can be found on the dark web, it also has other legitimate options such as chess clubs or book clubs, but because of the anonymity, the user will not know whom he/she is interacting with. Inside the dark web, anonymity and lawless nature make the crimes which exist otherwise in our society hard to trace.  The payment procedure inside the dark web is also different from the World Wide Web. Most often, Bitcoin and Monero cryptocurrency are used for the transactions.    RELATED READ: Knock Knock! Cybercriminal at Your Doorstep   What’s the difference between the deep web and dark web? The dark web is part of the entire deep web and is hidden from regular browsing access. Most people confuse the deep web and the dark web as one entity. It is not. The deep web content includes anything hidden and restricted behind the security wall such as content which otherwise requires paywall or sign-in or blocked by the author. Content which cannot be easily accessible on regular internet such as medical records, membership websites, paid content are available on the deep web; hence it is also called Invisible Web.  No one really knows the total size of the internet, but the experts believe that the standard World Wide Web consists of only 4% internet, the deep web consists of 90% and dark web consists of 6% of the entire internet.  ALSO READ: Technology has changed the way we work amid the COVID-19 crisis: A look at in-demand technologies Image: Kalkine     Also read: It happens again, NZX being bullied by Cyber-attackers- Down for the fourth day   What kind of risk companies face due to the dark web?  The Into the Web of Profit report listed below threats various organisations around the world are facing, especially the ones who have weak or insufficient cybersecurity measures.   Malware attacks Distributed denial of service (DDoS) attacks Botnets Trojan, keyloggers, exploits  Espionage  Credentials access  Phishing  Refunds Customer data Operational data Financial data Intellectual property/ trade secrets    Also read: Cybersecurity and the Requirement of a Resilient Environment in Australia  Are there advantages and disadvantages to the dark web?  The dark web provides complete anonymity, the users get complete privacy to perform any activity, be it illegal or legal. Many countries in the world still have authoritarian regimes offering no civil rights to their people. To such oppressed lot, the dark web provides an opportunity to access news, information, data and also express their views. The dark web is also a perfect place for law agencies to map criminal activities while being undercover. It is also easy to commit gruesome crimes through the dark web as it is complicated and lawless. Criminals can easily use the dark web to compromise someone's privacy, steal data or private information or even hire someone to commit murder.  Do internet users need to be concerned about the dark web?  The simple answer is no unless the user is using the dark web. Study says that most young people visit the dark web out of curiosity. They do not want to indulge in any criminal activity but want to see how the hidden and secret world of the dark web operates. And that is where the possibility of the electronic device IP address getting hacked by other criminals to perform their criminal activities lies.  The earliest use of darknet dates back to the year 2000. Freenet was created at the University of Edinburgh based on a student research paper. Ian Clark wrote the paper in 1999 on the possibility of such an encrypted internet base. Freenet was created to oppose censorship and provide a platform for free speech. The most powerful dark web is TOR, and it was created by the United States government to have a secure encrypted communication in case of emergency and complete disaster. Even today, many law agencies are secretly active inside the world of the dark web to gain access in the criminal world and stay one step ahead.

What is data warehousing? Data warehousing is defined as the method of gathering & handling data from different sources to get meaningful output and insights.

Thus, the people involved in decision making do not have to rely on hunches, incomplete data, and poor quality data. It also reduces the risk of delivering slow and inaccurate data. How does a data warehouse work? A data warehouse is like a central repository where the data comes from various sources. The data streams into the data warehouse from the transactional system and other relational databases. These data could either be structured, semi-structured or unstructured. These data get processed, altered, and consumed in a way that the end-user can gain access to the processed data in the data warehouse via business intelligence (BI) devices, SQL clients and spreadsheets. A data warehouse merges the data that comes from various sources into a complete database. The biggest advantage of this merged data is that the Company can analyze the data more holistically. It also makes the process of data mining smooth. Copyright © 2021 Kalkine Media Pty Ltd. Component of a data warehouse A data warehouse can be divided into four components. These are: Load Manager Load Manager, also known as the front component, does operations related to the mining and loading the data into a data warehouse. Load manager transforms the data for entering into Data warehouse. Warehouse Manager The warehouse manager manages the data within the data warehouse. It analyses data to confirm that the data in the data warehouse is steady. It also conducts operations such as the creation of indexes and views, generation of denormalization and aggregations, modifying and integrating the source data. Query Manager Query Manager is a backend component that does operations concerning the supervision of user queries. End-User access tools End-User access tools comprise data reporting, query tools, application development tools, EIS tools, data mining tools, and OLAP tools. Roles of Data Warehouse Tools and Utilities The tools and utilities in a data warehouse are used for: Data extraction: The data extraction process involves gathering data from heterogeneous sources. Data cleaning: Data cleaning consists of searching for any error in the data. Data transformation: Data transformation process involves changing the data into a data warehouse setup. Data loading: This process involves data sorting, recapping, consolidating, verifying integrity. Refreshing: This process requires revising data sources to the warehouse. Application of data warehouse Data warehouse plays a considerable role across multiple sectors. Some of the sectors it caters to are highlighted below. Aviation sector In the aviation sector, a data warehouse’s role can be seen in crew assignment, route profitability analysis, any promotional activity. Banking Industry In the banking sector, the focus is on risk management, policy reversal, customer data analysis, market trends, government rules and regulations and making financial decision. Through a data warehouse, banks can manage the resources available on the deck effectively. Banks also take the help of a data warehouse to do market research, analyze the products they offer, develop marketing programs. Retail industry Retailers act as an intermediary between the producers and the customers. Hence, these retailers use a data warehouse to maintain the records of both producers as well as the customer to maintain their existence in the market. Data warehouses help track inventory, advertisement promotions, tracking customer buying trends and many more. Healthcare industry In the healthcare industry, a data warehouse is used to predict the outcome of any test and taking relevant action accordingly. Data warehouses help them to generate patient treatment report, offer medical services, track the medicine inventory. Many patients visiting hospital have health insurance. Through a data warehouse, hospitals maintain the list of insurance providers.
