The Unassuming Economist

From the World Economic Outlook Update, July 2018:

“Global growth is projected to reach 3.9 percent in 2018 and 2019, in line with the forecast of the April 2018 World Economic Outlook (WEO), but the expansion is becoming less even, and risks to the outlook are mounting. The rate of expansion appears to have peaked in some major economies and growth has become less synchronized. In the United States, near-term momentum is strengthening in line with the April WEO forecast, and the US dollar has appreciated by around 5 percent in recent weeks. Growth projections have been revised down for the euro area, Japan, and the United Kingdom, reflecting negative surprises to activity in early 2018. Among emerging market and developing economies, growth prospects are also becoming more uneven, amid rising oil prices, higher yields in the United States, escalating trade tensions, and market pressures on the currencies of some economies with weaker fundamentals. Growth projections have been revised down for Argentina, Brazil, and India, while the outlook for some oil exporters has strengthened.

The balance of risks has shifted further to the downside, including in the short term. The recently announced and anticipated tariff increases by the United States and retaliatory measures by trading partners have increased the likelihood of escalating and sustained trade actions. These could derail the recovery and depress medium-term growth prospects, both through their direct impact on resource allocation and productivity and by raising uncertainty and taking a toll on investment. Financial market conditions remain accommodative for advanced economies—with compressed spreads, stretched valuations in some markets, and low volatility—but this could change rapidly. Possible triggers include rising trade tensions and conflicts, geopolitical concerns, and mounting political uncertainty. Higher inflation readings in the United States,where unemployment is below 4 percent but markets are pricing in a much shallower path of interest rate increases than the one in the projections of the Federal Open Market Committee,could also lead to a sudden reassessment of fundamentals and risks by investors. Tighter financial conditions could potentially cause disruptive portfolio adjustments, sharp exchange rate movements, and further reductions in capital inflows to emerging markets, particularly those with weaker fundamentals or higher political risks.

Avoiding protectionist measures and finding a cooperative solution that promotes continued growth in goods and services trade remain essential to preserve the global expansion. Policies and reforms should aim at sustaining activity, raising medium-term growth, and enhancing its inclusiveness. But with reduced slack and downside risks mounting, many countries need to rebuild fiscal buffers to create policy space for the next downturn and strengthen financial resilience to an environment of possibly higher market volatility.”

From Francis Diebold’s Blog:

“There is little doubt that climate change — tracking, assessment, and hopefully its eventual mitigation — is the burning issue of our times. Perhaps surprisingly, time-series econometric methods have much to offer for weather and climatological modeling (e.g., here), and several econometric groups in the UK, Denmark, and elsewhere have been pushing the agenda forward.

Now the NYU Volatility Institute is firmly on board. A couple months ago I was at their most recent annual conference, “A Financial Approach to Climate Risk”, but it somehow fell through the proverbial (blogging) cracks. The program is here, with links to many papers, slides, and videos. Two highlights, among many, were the presentations by Jim Stock (insights on the climate debate gleaned from econometric tools, slides here) and Bob Litterman (an asset-pricing perspective on the social cost of climate change, paper here). A fine initiative!”

From a new Econbrowser post by James Hamilton:

“Why does a low or negative spread predict future economic weakness? One factor may be the Fed’s tightening cycle. Historically the inflation rate would at times start climbing above where the Fed wanted it. The Fed responded by raising the short-term rate, the traditional instrument of monetary policy. The market response of long-term rates to the higher short rates was significantly more muted. The result is that the yield spread narrowed as the tightening cycle continued. The Fed often found itself behind the curve, and the last short-term rate hikes were likely a contributing factor to some historical economic recessions.

But we’re still very early in the current tightening cycle. The 3-month Treasury bill has not gone up so far by nearly as much as it did in previous complete cycles, and inflation is still very moderate. So I don’t think it’s time to run for cover just yet. However, if the Fed were to raise the short rate by another 100 basis points without any move up in long rates, we would be into inverted territory, and I would be very concerned. Not a danger sign yet, but definitely an indicator to keep watching.”

A new paper finds that “Gross domestic income and gross domestic product—GDI and GDP—measure aggregate economic activity using income and expenditure data, respectively. Discrepancies between the initial estimates of quarterly growth rates for these two measures appear to have some predictive power for subsequent GDP revisions. However, this power has weakened considerably since 2011. Similarly, the first revision to GDP growth has less predictive power in forecasting subsequent revisions since 2011. One possible explanation is that evolving data collection and estimation methods have helped improve initial GDP and GDI estimates.”

David Mihalyi and Tommy Morrison at NRGI created a World Economic Outlook Forecast Tracker that enables users to see how IMF economic projections have evolved over time. On it, you can select from an expansive list of countries and country groupings to track how IMF forecasts evolved year-to-year for dozens of economic indicators, such as GDP growth, government revenues and the budget deficit as well as the price of various commodities. The app shows an animated plot of the forecasts and historical values over 10 years, as well as providing a data download and a plot download (example attached).
