• The economics of mobile money - VoxEU Mobile money has transformed the landscape of financial inclusion in developing and emerging market countries, leapfrogging the provision of formal banking services. This column explains how mobile money potentially helps ameliorate several areas of market failure in developing economies, including saving, insurance, and the empowerment of women. It illustrates these effects using examples from aburgeoning empirical literature and concludes that the system-wide effects of mobile money may be even greater than current studies suggest.
• A Tax That Could Fix Big Tech - Paul Romer It is the job of government to prevent a tragedy of the commons. That includes the commons of shared values and norms on which democracy depends. The dominant digital platform companies, including Facebook and Google, make their profits using business models that erode this commons. They have created a haven for dangerous misinformation and hate speech that has undermined trust in democratic institutions. And it is troubling when so much information is controlled by so few companies. What is the best way to protect and restore this public commons? Most of the proposals to change platform companies rely on either antitrust law or regulatory action. I propose a different solution. Instead of banning the current business model — in which platform companies harvest user information to sell targeted digital ads — new legislation could establish a tax that would encourage platform companies to shift toward a healthier, more traditional model. ...
• The Economics of Donald J. Keynes - Paul Krugman I made a bad economic call on election night 2016, predicting a Trump recession. But I quickly realized that political dismay had clouded my judgment, and retracted the call three days later. "It's at least possible," I wrote on Nov. 11, 2016, "that bigger budget deficits will, if anything, strengthen the economy briefly." What I didn't realize at the time was just how much bigger the deficits would get. Since 2016, the Trump administration has, in practice, implemented the kind of huge fiscal stimulus followers of John Maynard Keynes pleaded for when unemployment was high — but Republicans blocked. Contrary to what Donald Trump and his supporters claim, we are not seeing an unprecedented boom. ...
• Improving the Phillips Curve with an Interaction Variable - FRBSF A key challenge for monetary policymakers is to predict where inflation is headed. One promising approach involves modifying a typical Phillips curve predictive regression to include an interaction variable, defined as the multiplicative combination of lagged inflation and the lagged output gap. This variable appears better able to capture the true underlying inflationary pressure associated with the output gap itself. Including the interaction variable helps improve the accuracy of Phillips curve inflation forecasts over various sample periods.
• Improving Labor Force Participation - macroblog Without question, the U.S. labor market has tightened a lot over the last few years. But a shifting trend in labor force participation—and especially a rise in the propensity to seek employment by those in their prime working years—seems to be relieving some labor market pressure. From the first quarter of 2015 to the first quarter of 2019, the labor force participation (LFP) rate among prime-age workers (those between 25 and 54 years old) increased by about 1.5 percentage points (see the chart below), adding about 2 million workers more than if the participation rate had not increased. ...
• Two Measures of Core Inflation: A Comparison - Dallasfed.org Abstract: Trimmed-mean Personal Consumption Expenditure (PCE) inflation does not clearly dominate ex-food-and-energy PCE inflation in real-time forecasting of headline PCE inflation. However, trimmed-mean inflation is the superior communications and policy tool because it is a less-biased real-time estimator of headline inflation and because it more successfully filters out headline inflation's transitory variation, leaving only cyclical and trend components.
• Smith, MMT, and science in economics - John Cochrane Many blog readers have asked for my opinions of "Modern Monetary Theory." I haven't written yet, because I try to read about things in some detail, ideally from original sources, before reviewing them, which I have not done. Life is short. From the summaries I have read, some of the central propositions of MMT draw a false conclusion from two sensible premises. 1) Countries that print their own currencies do not have to default on excessive debts. They can always print money to pay off debts. True. 2) Inflation in the end can and must be controlled by raising taxes or cutting spending, sufficiently to soak up such printed (non-interest-bearing) money. True. The latter proposition is the heart of the fiscal theory of the price level, so I would have an especially tough time objecting. It does not follow that the US need not worry about deficits, and may happily borrow tens of trillions to finance all sorts of spending. ...
• Housing market and bank lending effects on young firms and local economies - VoxEU Young firms live a financially precarious life, often dependent on self-funding tied to the value of the business owners' homes. This column uses data from the US to show that housing market fluctuations play a major role in driving medium-term changes in young firm employment shares. As young firms hire a disproportionate number of younger and less-educated workers, these groups are disproportionately affected by house price fluctuations.
• The economy isn't getting better for most Americans. But there is a fix - Heather Boushey The economy is getting bigger, but not better. Not for most Americans, anyway. In the United States, additional income from productivity and growth has been going mostly to those at the top of the income and wealth ladder. Between 1979 and 2016, the US national income grew by nearly 60%, but after accounting for taxes and transfers, the bottom half of the income distribution experienced incomes rising by 22%, while those in the top 10% had income gains that were almost five times as much – 100%. As income inequality widens, it's calcified into some at the top accumulating larger and larger stocks of assets – money, but also property, stocks, bonds and other kinds of capital. In the United States, the distribution of wealth is even more severely unequal than income. Since 1979, wealth gains at the top have grown even faster than income; those in the top 1% now control about 40% of all wealth in the US economy, and the top 0.1% control more than 20% – three times as much as the late 1970s. ...
• The Great Depression: An Intake from "Slouching Towards Utopia?: An Economic History of the Long Twentieth Century 1870-2016" - Brad DeLongThis is the current draft of chapter 10 of Slouching Towards Utopia?. I am, again, of several minds with respect to it. I think it says what really needs to be said. I am not sure it says it in the right length. And I am not sure that I have successfully assembled the puzzle pieces in the right way... So tell me what you think of it:
• The Sabotage Years - Paul Krugman Do you remember the great inflation scare of 2010-2011? The U.S. economy remained deeply depressed from the aftereffects of the burst housing bubble and the 2008 financial crisis. Unemployment was still above 9 percent; wage growth had slowed to a crawl, and measures of underlying inflation were well below the Federal Reserve's targets. So the Fed was doing what it could to boost the economy — keeping short-term interest rates as low as possible, and buying long-term bonds in the hope of getting some extra traction. But Republicans were up in arms, warning that the Fed's policies would lead to runaway inflation. ...
