Value-based pricing refers to a strategy where the price of any particular commodity is being set depending on its perceived value of the product.
For pricing the credit risk, this is perhaps one of the earliest reduced-form versions. It was developed by Stuart Turnbull and Robert Jarrow. It uses dynamic analysis and multi-factor of interest rates to determine the probability of default.
Defining Macroeconomics Macroeconomics is a branch of Economics that evaluates the functioning of an economy as a whole. It studies the performance and behaviour of key economic indicators such as economy’s output of goods and service, exchange rates, the growth of output, the rate of unemployment and inflation, and balance of payments. Macroeconomics emphasises on the policies and economic behaviour that influence consumption and investment, exchange rates, trade balance, money flow, fiscal and monetary policy, interest rates, national debt, and factors influencing wages and prices. The scope of the subject goes beyond microeconomic topics like the behaviour of individuals, firms, markets, and households. History of Macroeconomics Macroeconomics originated with John Maynard Keynes post the great depression when the classical economist failed to explain the great economic fallout. Classical economics mostly comprised theories that studied pricing, distribution, and supply & demand. In 1936, John Maynard Keynes published – The General Theory of Employment, Interest and Money – effectively changing the perception of how macroeconomic problems should be addressed. The theories of Keynes shifted to focus on aggregate demand from the aggregate supply. Keynes said: ‘In the long run, we are all dead’. This statement was made to dismiss the notion that the economy would be in full employment in the long run. Later the theories developed by Keynes formed the basis for Keynesian economics, which gained popularity over other schools of thoughts including Neoclassical economics. Neoclassical economics emerged in the 1900s. It introduced imperfect competition models, which included marginal revenue curves, indifference curves. The theories in neoclassical economics argued about the efficient allocation of limited productive resource. Neoclassical economists explain consumption, production, pricing of goods and services through supply and demand. Some assumptions of this thought were an individual’s motive is to maximise utility as companies seek to maximise profits. Individuals make rational choices and act independently on perfect information. Over the years, many new schools of thought in Macroeconomics have found footing in the economics world. These include monetarist theories, new classical economics, new Keynesian economics, and supply-side macroeconomics. Difference between Macroeconomics and Microeconomics Major topics in Macroeconomics National income and output The estimation of national income includes the value of goods and services produced by a country in a financial year domestically and internationally. National income essentially means the value of total output generated by an economy in a year. National income can also be referred as national expenditure, national output or national dividend. Financial systems Understanding financial systems is an important concept in macroeconomics. A financial market is a market for financial securities and commodities, including bonds, shares, precious metal, agriculture goods. It is important for an economy to have markets where buyers and sellers can exchange goods. A financial market helps in the allocation of resources. Financial markets facilitate savings mobilisation, i.e. financial intermediaries channelise funds from savers to borrowers. Investment remains on the agenda for policymakers to promote growth, and financial markets facilitate funds by allowing individuals to invest in bonds and stocks, which are issued by institutions seeking funds for investments. Business cycles A Business cycle or an economic cycle refers to fluctuations in production, trade or economic activities. The upward and downward movement generally indicates the fluctuations in gross domestic product. A business cycle has four different phases: expansion, peak, contraction, and trough. An expansion in an economy is when economic growth, employment, prices are rising. The peak is achieved when the economy is producing maximum output, inflation is visible, and employment levels are running high. After a peak, the economy enters into contraction, which leads to a fall in employment, depleting economic activity, and stabilisation in prices. At trough, the economy is at the bottom of the cycle, and the next phase of expansion starts after the trough. Interest rates Macroeconomics also deals with interest rates in the economy. Interest rate policy of an economy is formulated and maintained by the central bank. A central bank manages the money supply in the economy. The intervention by the central bank to propel economic growth is called monetary policy. The monetary policy of an economy seeks to maintain employment and inflation in the economy. The motive of the monetary policy is to achieve full employment and maintain stable prices.
What is a Market Index? A market index could be defined as a representation of a security market, market segment, or asset class of freely tradable market instruments. A market index is primarily made up of constituent marketable securities and is re-calculated on a daily basis. There are basically two forms or variations of the same market index, i.e., one version based upon the price return known as a price return index, and one version based upon total return know as a total return index. Why Do We Need A market Index? Ideally, a large number of market participants including investors and institutional funds gather and analyse vast amounts of information about security markets; however, doing so could be a very troublesome and tiring task as the work is both time consuming and data-intensive. Thus, a large number of market participants prefer to use a single measure that could represent and consolidate a plethora of information while reflecting the performance of an entire security market of interest. This is where market indexes play a major role as they are often a simple measure to reflect the performance of any underlying market of interest. For example, S&P500, NASDAQ, are believed to reflect the true performance and picture of the U.S. stock market in particular and U.S. economy in general. Likewise, many indexes such as S&P/ASX 200 is believed to reflect the performance of the Australian stock market and so on. Index Construction Constructing a market index is almost similar to constructing a portfolio of securities as the construction of an index requires: Target Market and Security Selection The first and the primary decision in constructing an index is to identify the target market and select financial instruments which reflect the true nature of the underlying market. The target market, which determines the investment universe and securities available for inclusion, could be based on any asset class, i.e., equities, fixed income, commodities, real estates or on any geographic region. Once the target market is identified, the next step is to select securities which represent the true nature of the target market and decide on the number of securities to be included in the index. Ideally, a market index could be of all securities in the target market or a representative sample of the target market. For example, some indexes such as FTSE 100, S&P 500, S&P/ASX 200, fix the number of stocks to be included in the index while indexes like Tokyo Stock Price Index (or TOPIX) select and represents all of the largest stocks, known as the First Selection. For such indexes, the included securities must meet some basic parameters like pre-decided market capitalisation, the number of shares outstanding, to remain in the index. Weight Allocation The weight allocation varies considerably among indexes depending upon the method of weight allocation, and it basically decides on how much weight each security in an index carry. The method of weight allocation is one of the most important parts that investors need to understand thoroughly as it has a substantial impact on the value of an index. Some of the most widely-used weight allocation methods are as below: Price Weighting This method was originally used by Charles Dow to construct the Dow Jones Industrial Average (or DJIA) and is one of the simplest methods. The price weight method determines the weight of each individual security of an index by dividing the price of the security by the sum of prices of all securities. In simple terms, each security gets the weight of its price in proportional to the total price of the index. The primary advantage of this method is its simplicity; however, the method leads to arbitrary weights for each security as the method is highly sensitive to some market actions such as stock split. Equal Weighting As the name suggests, this method assigns equal weight to all securities in an index. Just like equal weighting, the major advantage of this method is its simplicity; however, this method tends to underrepresent the value of large securities and overrepresent the value of smaller securities. Market-Capitalisation Weighting Market-Capitalisation method weight each constituent by dividing its market capitalisation with the total market capitalisation of the index, i.e., the sum of the market capitalisation of each constituent. The market capitalisation could be determined by multiplying the number of outstanding shares of the security with its market price per share. Rebalancing and Reconstitution Rebalancing of a market index could be defined as the adjustment to the weights of the constituent securities. Depending upon the method of weighting an index, the weight of each individual security tends to change due to market actions or price appreciation and deprecation, in similar fashion to a stock portfolio requires scheduled rebalancing. A majority of market indexes are rebalanced on a daily basis as price tends to often change regularly. On the other hand, reconstitution could be ideally defined as the process to change the constituent of a market index. As suggested above, many market indexes such as TOPIX require each constituent security to meet some parameters for the inclusion; however, due to market dynamics, various securities tend to get added or removed from an index time to time. Uses of Market Index Originally, market indexes were created to provide a sense to investors on how a security market performed on a given day. However, with the development of the modern finance theory and growing numbers of indexes in the market, uses of market indexes have been expanded significantly. Some of the major uses of market indexes are as below: To Gauge the market sentiment A market index is usually a collection of the opinion of market participants; thus, they reflect the attitude and behaviour of the market participants, making them one of most widely used tool to gauge the market sentiment. To measure and model the risk and return profile of a market Market indexes could serve as a proxy for systematic risk in many popular models such as the Capital Asset Pricing Model (or CAPM). The market portfolio, which represents the systematic risk of the market often uses a market index, as a proxy of the market portfolio as including the whole population or all stocks in the model could lead to wrong output, and it could be very costly and cost consuming. Serves as a Performance Benchmark Market indexes often serve as a performance benchmark for individual investors and especially large investors such as mutual funds, ETFs, pension funds, and large banks.
The Fama French Model is a CAPM (Capital Asset Pricing Model). It?s a total of value, size, and market risk factors in CAPM.
