Walras' Law

A famous economic theory, it states that if there is extra supply in one particular market, to balance it out, there should be additional demand in another.

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.

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.

An act created to bolster the educational resources of US-based universities and colleges. The law is intended to aid post-secondary students financially.

This depicts the responsibility of a couple of or more partners to be responsible for fulfilling a liability or pay back a debt. It enables involved parties to share associated risks that are involved with taking on debt and even provide cover in lawsuits as and when required.

What is Keynesian economics? Keynesian economics is the economic theory that states demand is the driver of economic growth. This economic theory also states that fiscal aid helps recover an economy from a recession. Certain Keynesian economic principles stand in stark contrast to the Classical theory of economics. The theory was given by John Maynard Keynes in the 1930s and published in Keynes’ “General Theory of Employment, Interest and Money” in 1936. The Keynesian theory stated that government spending was an essential factor in increasing demand and maintaining full employment. What are the theories under Keynesian economics? Aggregate demand is affected by a host of factors: Aggregate demand is affected by various factors public and private factors. Monetary and fiscal policy both affect the level of aggregate demand in the economy. Any decision taken by the monetary authority or the government greatly affects the economy’s level of demand. Say’s Law proposes that supply generates its own demand. However, Keynesian economics suggests that demand is the driver of supply and overall growth in the economy. Sticky Wages: According to the theory of sticky wages, employers would prefer laying off workers over decreasing the existing workers’ wages. This happens because even in the absence of labour unions, workers would still resist wages cuts. Even if the employers were to reduce wages, it would lead to economic depression as demand would fall and people would become more cautious about their spending. Keynes advocated that the labour markers do not function independently from the savings market. Therefore, prices and wages respond slowly to changes in supply and demand. Liquidity Trap: Liquidity trap refers to an economic scenario where there is a contraction in the economy despite very low interest rates. This contrasts with the relationship between interest rates and investment given in Classical economics. How is Keynesian economics different from Classical economics? Classical economics states that the economy self-regulates in case of a disequilibrium. Any deviations from the market equilibrium would be adjusted on its own without any government regulation. However, Keynesian economics propagates that government intervention must maintain equilibrium or come out of an economic downturn. Keynesian economics highlights the importance of monetary and fiscal policy, while Classical economics does not mention any government intervention. Another crucial difference is that Classical economics suggests that governments should always incur less debt, while Keynesian economics advises that governments should practice deficit financing during a recession. Classical economics states that government spending can be harmful as it leads to crowding out of the private investment. However, it has been later established that this happens when the economy is not in a recession. Government borrowing competes with private investment leading to higher interest rates. Thus, Keynesian economics is of the view that deficit spending during a recession does not crowd out private investment. What are the policy measures advocated by Keynesian economics? According to Keynes, adopting a countercyclical approach can help economies stabilise. This means that governments must move in a direction opposite to the business cycles. The theory also states that governments should recover from economic downturns in the short run itself, instead of waiting for the economy to recover over time. Keynes wrote the famous line, “In the long run, we are all dead”. The short run knowledge of the economy would be far better than the long run prediction made by any government. Thus, it makes sense for governments to focus on short run policies and maintain short run equilibrium. Keynes’ multiplier effect states that government spending would increase the GDP by a greater amount than the increase in government spending. This multiplier effect established a reason for governments to go for fiscal support when the economy requires it. What have been the criticisms of Keynesian economics? The initial stages of Keynesian economics propagated that monetary policy was ineffective and did not play any role in boosting economic growth. However, the positive effects of monetary policy are well established and have been integrated into the new Keynesian framework. Another criticism is that the advantage of the fiscal benefits to the GDP cannot be measured. Thus, it becomes difficult to fine-tune the fiscal policy to suit the economic scenario better. Also, the Keynesian belief of increased spending leading to economic growth may lead to the government investing in projects with a vested interest. It could also lead to increased corruption in the economy. The theory of rational expectations suggests that people understand that tax cuts are only temporary. Thus, they prefer to save up the income left behind to pay for future increases in taxes. This is the Ricardian Equivalence theory. Thus, fiscal policy may be rendered ineffective due to this. Supply-side economics has also shown contrast to Keynesian beliefs. During the stagflation in the 1970s, the Phillips curve failed, bringing out the importance of supply-side economics.
