Decriminalization versus Legalization

By Jeffrey Miron.

"A new study argues that recent drug de-criminalizations in Oregon and Washington caused substantial increases in drug overdoses.

Is this plausible? And does it imply that prohibition is better than legalization?

Yes, and no.

Decriminalization means elimination of criminal penalties for drug possession. Legalization means elimination of criminal penalties for production and sale.

Standard economics suggests that decriminalization, by reducing the full price of purchasing drugs, shifts demand outward, implying greater use.

This causes, since production and sale are still illegal, a larger underground market and therefore more of the associated negatives. These include increased violence, because black market participants cannot resolve disputes with courts and lawyers; and additional overdoses, because quality control is difficult in black markets.

Thus the study’s result makes sense. But rather than supporting prohibition, it shows that full legalization – rather than decrim – is the right path. Indeed, if policy legalizes only one side of the market, it should be supply rather than demand. A related point is that legalization must not include too much regulation and taxation; that just re-creates the black market.

A possible qualification is that some decrims seem to have avoided increased violence or overdoses. The likely explanation is that in these instances, policy de-escalated supply side enforcement along with decriminalizing."

After decades of warnings, new data suggest the Atlantic’s vital circulation may withstand climate warming better than feared

See Shifting currents by Paul Voosen in Science. Excerpts:

"Climate models have long warned that global warming could weaken “deep-water formation”—the density-driven sinking that is the engine of the AMOC. The logic is straightforward: As Greenland’s ice sheets melt and sea ice formation declines, North Atlantic waters will freshen. Combined with warmer sea temperatures, the freshening makes surface waters more buoyant. The AMOC was thought to have shut down abruptly during past climate warmings, and a handful of researchers now argue such a tipping point could occur this century. A sputtering AMOC could trigger a sharp cooldown in northwestern Europe, rising seas along the U.S. east coast, and shifts in tropical rainfall."

"most climate researchers think the AMOC is more resilient than these worst case scenarios make it seem. Emerging evidence suggests the AMOC may not have actually collapsed in the warm climates following ice ages. More detailed climate models suggest it could weaken but not collapse in the current surge of warming. And studies of the AMOC’s present behavior do not yet show any clear signs of trouble. They’re also exposing new facets of the circulation that could buffer any eventual weakening."

"That stately flow actually swings wildly year to year, masking any long-term trend, the first RAPID measurements showed. Swings between apparent decline and recovery have since become a hallmark of AMOC monitoring, and a recurring source of alarm and reassessment."

"Gerard McCarthy remembers well the first time he saw an AMOC decline. It was 2011, and McCarthy, now a climate scientist at Maynooth University, had just joined the RAPID team. His first task was calculating AMOC’s strength. Beginning in 2009, it plunged. “Everyone was like, ‘The new guy made a mistake,’” he recalls. Others checked the numbers. The drop held. “We all realized that something dramatic had happened.”

What happened was not caused by climate change, but rather the weather. That winter, unusual swings in air pressure weakened the jet stream and shifted wind patterns, disrupting the AMOC’s flow. The decline likely contributed to a frigid European winter in 2009 and, by leaving more heat in tropical basins, also led to an active Atlantic hurricane season the following summer."

 "It seems the AMOC is not a single conveyor belt, but a belt of belts, each part operating semiautonomously."

"OSNAP has changed the picture in other ways, including by showing that overturning occurs not so much in the Labrador Sea, as models suggested, as it does farther north, in the Irminger and Iceland basins. Additional data suggest deep-water formation is migrating even farther north, into the Arctic Ocean, following the retreat of sea ice, Ă…rthun says. “You’re expanding the reach of this cooling machine.” The northward migration could make the AMOC more resilient to warming"

"New climate model runs that capture more realistic melt from the Greenland Ice Sheet are less dire. In two preprints posted online in the past year—one led by Chuncheng Guo, a climate scientist at the Danish Meteorological Institute (DMI), the other led by Oliver Mehling, an ocean modeler at UU—researchers created multiple simulations where carbon emissions continued until 2250 and temperatures rose by up to 7°C. In both studies the AMOC weakened, losing about 40% of its strength. But it never collapsed. Both studies also suggest the weakening is reversible"

"that resilience persisted even in the face of catastrophic warming."

 "even if atmospheric carbon dioxide levels quadrupled, driving extreme warming, the AMOC would decline by 40% after 20 or so years—but once again, it would rebound."

"Evidence from past ice ages seemed to suggest the AMOC switched off entirely when massive pulses of freshwater from the melting of the North American ice sheet poured into the Atlantic. But new work, also presented at Ocean Sciences, suggests the AMOC may not have collapsed at all during these periods."

China’s Economy Is in Worse Shape Than You Think

The estimate of 4.3% GDP growth is below Beijing’s lowest projection—and it’s probably far too high

By Joseph C. Sternberg. Excerpts:

"Beijing’s statisticians on Wednesday said the gross domestic product grew 4.3% year-on-year in inflation-adjusted terms in the April through June quarter. China’s economic data are notoriously prone to fiddling for political purposes. And only this March, the Communist Party set a GDP growth target range of 4.5% to 5% for the year, its most pessimistic since the 1990s."

"Meanwhile there’s accumulating evidence that the country’s true GDP growth rate may be zero, or that the economy is in outright recession. Retail sales were a bright spot in the latest data, increasing 1% year-on-year in June, but looking across recent months this measure of domestic household consumption may be stuck in neutral. Measures of investment are in free fall: Fixed-asset investment has declined 5.7% year-to-date and real-estate investment is down 18%."

"Crude imports in July hit their lowest level in roughly a decade."

"refinery output also is declining"

"demand for energy within China . . . is dropping rapidly."

"it’s hard to find anyone who thinks any of this (more economic “stimulus”) would launch a durable economic recovery. One reason domestic consumption is dipping is that previous iterations of the consumption subsidy (a trade-in scheme, akin to the Obama-era “cash for clunkers” in the U.S., that rewards replacement of old items) pulled forward in time purchases that households would have made anyway, without setting in motion a Keynesian virtuous circle of new corporate investment to meet higher demand. As for public works, China has enough and Beijing’s more important fiscal priority remains bailing out heavily indebted local governments." 

"Domestic consumption is unlikely to revive until the real-estate market has found its bottom." 

Evicting Wall Street From the Housing Market Will Be Messy

Law restricting activities of big investors in residential real estate could mean less cash to build new supply

By Carol Ryan of The WSJ. Excerpts:

"Under the 21st Century ROAD to Housing Act . . . investors who already own more than 350 family homes can’t buy any more from the existing housing stock."

"Any landlords that don’t already have scale will find it hard to expand their portfolios through the exemptions."

"Big landlords are being nudged to pour cash into the build-to-rent sector instead. This means taking on development risk and constructing entire rental neighborhoods from scratch. The benefit of constructing whole rental communities in one area is that they are much cheaper to maintain than homes that are scattered across dispersed neighborhoods."

"Build-to-rent is exempt from restrictions under the new law. Like multifamily apartment buildings, it is an area of the housing market in which large investors can continue to operate freely."

"Anyone considering putting money into the housing market . . . must now weigh the risk that future administrations could tighten the rules further."

"Returns on build-to-rent investments don’t look high enough to compensate for the risk."

"Build-to-rent communities are hard—or impossible under some zoning rules—to sell off individually to consumers"

"Eight large institutional investors were net sellers of more than 3,000 homes in the second quarter of this year, a fivefold increase in net-selling activity from the same period of last year"

"some smaller investors plan to cash out permanently by selling homes to individual home buyers over time"
