Deflation: a Business Perspective
Deflation: a business perspective Prepared by the Corporate Economists Advisory Group Introduction Early in 2003, ICC's Corporate Economists Advisory Group discussed the risk of deflation in some of the world's major economies, and possible consequences for business. The fear was that historically low levels of inflation and faltering economic growth could lead to deflation - a persistent decline in the general level of prices - which in turn could trigger economic depression, with widespread company and bank failures, a collapse in world trade, mass unemployment and years of shrinking economic activity. While the risk of deflation is now remote in most countries - given the increasingly unambiguous signs of global economic recovery - its potential costs are very high and would directly affect companies. This issues paper was developed to help companies better understand the phenomenon of deflation, and to give them practical guidance on possible measures to take if and when the threat of deflation turns into reality on a future occasion. What is deflation? Deflation is defined as a sustained fall in an aggregate measure of prices (such as the consumer price index). By this definition, changes in prices in one economic sector or falling prices over short periods (e.g., one or two quarters) do not qualify as deflation. Dec lining prices can be driven by an increase in supply due to technological innovation and rapid productivity gains. These supply-induced shocks are usually not problematic and can even be accompanied by robust growth, as experienced by China. A fall in prices led by a drop in demand - due to a severe economic cycle, tight economic policies or a demand-side shock - or by persistent excess capacity can be much more harmful, and is more likely to lead to persistent deflation. -
Carbonomics Innovation, Deflation and Affordable De-Carbonization
EQUITY RESEARCH | October 13, 2020 | 9:24PM BST Carbonomics Innovation, Deflation and Affordable De-carbonization Net zero is becoming more affordable as technological and financial innovation, supported by policy, are flattening the de-carbonization cost curve. We update our 2019 Carbonomics cost curve to reflect innovation across c.100 different technologies to de- carbonize power, mobility, buildings, agriculture and industry, and draw three key conclusions: 1) low-cost de-carbonization technologies (mostly renewable power) continue to improve consistently through scale, reducing the lower half of the cost curve by 20% on average vs. our 2019 cost curve; 2) clean hydrogen emerges as the breakthrough technology in the upper half of the cost curve, lowering the cost of de-carbonizing emissions in more difficult sectors (industry, heating, heavy transport) by 30% and increasing the proportion of abatable emissions from 75% to 85% of total emissions; and 3) financial innovation and a lower cost of capital for low-carbon activities have driven around one-third of renewables cost deflation since 2010, highlighting the importance of shareholder engagement in climate change, monetary stimulus and stable regulatory frameworks. The result of these developments is very encouraging, shaving US$1 tn pa from the cost of the path towards net zero and creating a broader connected ecosystem for de- carbonization that includes renewables, clean hydrogen (both blue and green), batteries and carbon capture.

Cryptocurrency: the Economics of Money and Selected Policy Issues
Cryptocurrency: The Economics of Money and Selected Policy Issues Updated April 9, 2020 Congressional Research Service https://crsreports.congress.gov R45427 SUMMARY R45427 Cryptocurrency: The Economics of Money and April 9, 2020 Selected Policy Issues David W. Perkins Cryptocurrencies are digital money in electronic payment systems that generally do not require Specialist in government backing or the involvement of an intermediary, such as a bank. Instead, users of the Macroeconomic Policy system validate payments using certain protocols. Since the 2008 invention of the first cryptocurrency, Bitcoin, cryptocurrencies have proliferated. In recent years, they experienced a rapid increase and subsequent decrease in value. One estimate found that, as of March 2020, there were more than 5,100 different cryptocurrencies worth about $231 billion. Given this rapid growth and volatility, cryptocurrencies have drawn the attention of the public and policymakers. A particularly notable feature of cryptocurrencies is their potential to act as an alternative form of money. Historically, money has either had intrinsic value or derived value from government decree. Using money electronically generally has involved using the private ledgers and systems of at least one trusted intermediary. Cryptocurrencies, by contrast, generally employ user agreement, a network of users, and cryptographic protocols to achieve valid transfers of value. Cryptocurrency users typically use a pseudonymous address to identify each other and a passcode or private key to make changes to a public ledger in order to transfer value between accounts. Other computers in the network validate these transfers. Through this use of blockchain technology, cryptocurrency systems protect their public ledgers of accounts against manipulation, so that users can only send cryptocurrency to which they have access, thus allowing users to make valid transfers without a centralized, trusted intermediary. -
The Keynesian Model in the General Theory: a Tutorial
The Keynesian Model in the General Theory: A Tutorial Raúl Rojas Freie Universität Berlin January 2012 This small overview of the General Theory is the kind of summary I would have liked to have read, before embarking in a comprehensive study of the General Theory at the time I was a student. As shown here, the main ideas are quite simple and easy to visualize. Unfortunately, numerous introductions to Keynesian theory are not actually based on Keynes opus magnum, but in obscure neo‐classical reinterpretations. This is completely pointless since Keynes’ book is so readable. Introduction John Maynard Keynes (1883‐1946) completed the General Theory of Employment, Interest, and Money [1] in December of 1935, right in the middle of the Great Depression. At that point, millions of workers in the US and Europe had been unemployed for years, and economic orthodoxy could not account for this “anomalous” situation. Keynes’ General Theory tries to tackle exactly this problem. Keynes rejected classical theories based on the idea that production creates its own demand, that is, that the economy always recovers to full employment after a shock. Therefore, Keynes called his treatise the General Theory because he conceived classical doctrine as only a special case of a more complete approach: “The classical theorists resemble Euclidean geometers in a non‐Euclidean world who, discovering that in experience straight lines apparently parallel often meet, rebuke the lines for not keeping straight (...) Yet, in truth, there is no remedy except to throw over the axiom of parallels and to work out a non‐Euclidean geometry. -

While MMT is not new, it has recently received wide- spread attention, particularly as government spending has increased dramatically in response to the ongoing COVID-19 crisis and concerns grow about how to pay for this increased spending. The essential message of MMT is that there is no financial constraint on government spending as long as a country is a sovereign issuer of cur- rency and does not tie the value of its currency to another currency. Both Canada and the US are examples of countries that are sovereign issuers of currency. In principle, being a sovereign issuer of currency endows the government with the ability to borrow money from the country’s cen- tral bank. The central bank can effectively credit the government’s bank account at the central bank for an unlimited amount of money without either charging the government interest or, indeed, demanding repayment of the government bonds the central bank has acquired. In 2020, the cen- tral banks in both Canada and the US bought a disproportionately large share of government bonds compared to previous years, which has led some observers to argue that the governments of Canada and the United States are practicing MMT. -

The Neoclassical Synthesis
Department of Economics- FEA/USP In Search of Lost Time: The Neoclassical Synthesis MICHEL DE VROEY PEDRO GARCIA DUARTE WORKING PAPER SERIES Nº 2012-07 DEPARTMENT OF ECONOMICS, FEA-USP WORKING PAPER Nº 2012-07 In Search of Lost Time: The Neoclassical Synthesis Michel De Vroey ([email protected]) Pedro Garcia Duarte ([email protected]) Abstract: Present day macroeconomics has been sometimes dubbed as the new neoclassical synthesis, suggesting that it constitutes a reincarnation of the neoclassical synthesis of the 1950s. This has prompted us to examine the contents of the ‘old’ and the ‘new’ neoclassical syntheses. Our main conclusion is that the latter bears little resemblance with the former. Additionally, we make three points: (a) from its origins with Paul Samuelson onward the neoclassical synthesis notion had no fixed content and we bring out four main distinct meanings; (b) its most cogent interpretation, defended e.g. by Solow and Mankiw, is a plea for a pluralistic macroeconomics, wherein short-period market non-clearing models would live side by side with long-period market-clearing models; (c) a distinction should be drawn between first and second generation new Keynesian economists as the former defend the old neoclassical synthesis while the latter, with their DSGE models, adhere to the Lucasian view that macroeconomics should be based on a single baseline model.
