The online overseas asset place of the US

A rustic’s web overseas asset place measures the worth of all of the property residents personal overseas minus the worth of property foreigners personal within the nation. It is a crucial statistic, as a result of all else equal, a better web overseas asset place means a rustic can anticipate increased future web revenue from overseas, and might thus plan on operating bigger future commerce deficits. One widespread approach to decompose adjustments within the web overseas asset place is to recognise that the place can enhance as a result of a rustic, on web, acquires further overseas property – i.e. it runs a present account surplus – or as a result of the market worth of present property owned overseas will increase relative to the worth of foreign-owned property within the nation.

The US has lengthy had a unfavorable web overseas asset place. However till 2007 it was comparatively small, by no means exceeding 20% of US GDP. In truth, the place was surprisingly small given the US historical past of huge and protracted present account deficits. In influential papers, Gourinchas and Rey (2007, 2014) emphasised the significance of valuation results in shaping the dynamics of the US web overseas asset place. On the time they had been writing, these revaluations appeared to maneuver persistently in favour of the US, particularly through the mid-2000s. The online impact was that the US appeared to benefit from the particular privilege of being persistently capable of borrow with out operating up a lot debt. Gourinchas and Rey and others argued that this privilege mirrored an asymmetry in cross-country portfolios, with Individuals proudly owning a number of direct funding and portfolio fairness property overseas – whose worth tended to rise over time – whereas US liabilities consisted disproportionately of low return US authorities bonds. 

Our paper (Atkeson et al. 2022) updates the historical past of the US web overseas asset place, utilizing knowledge assembled by the US Bureau of Financial Evaluation and the US Treasury within the Monetary Accounts of america. We discover that quite a bit has modified within the final 15 years. First and most notably, the US web overseas asset place has deteriorated very sharply, from unfavorable 5% of US GDP in 2007, to unfavorable 65% of US GDP by the third quarter of 2021. Such a big unfavorable web place is unprecedented. What has pushed this decline? What are the welfare implications for Individuals?

We begin by displaying that the decline within the US web overseas asset place over this era is usually pushed by valuation results, with present account deficits enjoying a minor function. In truth, these valuation results are so massive that the US web place is extra unfavorable by the tip of 2021 than the sum of all US present account deficits since 1992 (see Determine 1). That’s the reason we title our paper “The Finish of Privilege.”

Subsequent, we dig into the supply of those valuation results. We discover that valuation results have pushed down the US web overseas asset place as a result of the worth of foreign-owned property within the US has risen quickly. Which may sound shocking to readers beneath the impression that the US operates like a hedge fund, borrowing from overseas within the type of stable-in-value Treasury bonds, and investing abroad in unstable equity-like investments. However the US monetary accounts present that that stylised view of the US worldwide funding place is turning into growing outdated. Particularly, within the post-Nice Recession interval, foreign-owned fairness holdings within the US are massive, and comparable in worth to US-owned fairness property overseas (Determine 2). The US Bureau of Financial Evaluation estimates that the worth of those foreign-owned fairness holdings has surged over the previous 15 years, along side the spectacular bull run for the US inventory market over this era. On the identical time, the worth of US-owned property overseas has risen far more slowly, as overseas fairness markets massively under-performed the US (Determine 3). Thus, the market worth of US overseas liabilities has risen far more shortly than the market worth of US overseas property, miserable the US web overseas asset place.

Up thus far, all we have now performed is straightforward accounting. Our subsequent goal is to deal with the welfare implications of the decline within the US web overseas asset place. To take action requires a mannequin inside which we will simulate shocks that enhance US asset values. Farhi and Gourio (2019) develop a tractable macro asset pricing mannequin that can be utilized as an accounting framework to hint out the contributions of varied potential drivers of asset revaluations. They discover the relative roles in long term macro and asset valuation tendencies of (1) adjustments in agency market energy, (2) adjustments within the significance of intangible capital, and (3) adjustments in danger premia. Greenwald et al. (2022) conduct the same train. They conclude that an important driver of rising US fairness values between 1989 and 2017 was a collection of issue share shocks that reallocated output towards shareholders on the expense of staff. 

In our paper, we prolong a mannequin that’s much like those in Farhi and Gourio (2019) and Greenwald et al. (2022) to a world setting, in order that we will discover differential cross-country asset valuation dynamics and their implications for the present account and the online overseas asset place. In our mannequin, companies in every nation produce differentiated varieties. Every selection may be produced by a extra productive ‘chief’ agency, or by a fringe of much less productive potential opponents. In equilibrium, chief companies interact in restrict pricing, setting markups which are as massive as potential whereas nonetheless preserving their manufacturing monopoly. We use the mannequin to discover two completely different potential drivers of a US-specific improve in asset values. 

The primary speculation we entertain is that the productiveness differential between chief and follower companies has elevated within the US – however not in the remainder of the world. This results in an increase in US markups, in US monopoly earnings, and within the worth of US companies. From the standpoint of agency homeowners, the bounce in agency values seems as a windfall sudden extra return to fairness. And if these homeowners are abroad, the shock implies a everlasting improve within the share of US revenue accruing to foreigners. Thus, on this mannequin, the decline within the US web overseas asset place displays a redistribution of revenue away from Individuals and towards foreigners. We argue that this mannequin of agency values is in step with two key empirical details. First, it’s in step with the truth that measured company payouts relative to GDP have risen markedly within the US in latest a long time, whereas payouts in different international locations haven’t (see Determine 4). Second, the mannequin is in step with the truth that US present account deficits have usually been modest within the post-Nice Recession interval.

We additionally think about an alternate speculation for rising US asset values, which is that manufacturing has develop into extra intensive in types of capital which are poorly measured in nationwide accounts. Underneath this speculation, the worth of the US inventory market has risen as a result of US (however not overseas) companies have undertaken numerous funding in unmeasured intangible types of capital. Alongside a balanced development path, it seems that the upper markups versus extra intangible capital fashions are observationally equal. However in our open economic system setting, the 2 fashions exhibit very completely different dynamics within the transition from one balanced development path to a different. Particularly, if unmeasured capital turns into extra necessary, the mannequin predicts a interval of very massive (and counterfactual) present account deficits, because the US borrows to take a position. As a result of valuation positive factors replicate new capital accumulation there aren’t any windfall positive factors to overseas homeowners of US companies – whoever funds the unmeasured funding reaps the long run returns to that capital.

To conclude, rising worldwide fairness diversification has created highly effective new channels for shocks to propagate throughout nationwide borders. Surging US fairness values in a context of considerable overseas possession of US fairness have led to a collapse within the US web overseas asset place. Financing this web debt to the remainder of the world requires, in expectation, that the US run bigger commerce surpluses shifting ahead. Our most well-liked interpretation of the surge in US fairness values is that US companies unexpectedly grew to become extra worthwhile, whereas overseas companies didn’t. In a closed economic system, this shock would redistribute to American agency homeowners on the expense of American staff. In our open economic system mannequin, the state of affairs for Individuals is worse: a big share of the revenue misplaced by American staff accrues to overseas homeowners of US companies.  Nonetheless, this reallocation is likely to be environment friendly from an ex ante perspective. A key open query right here is whether or not earnings are rising within the US due to the expansion of very productive famous person companies within the US (Baqaee and Farhi 2017), or alternatively as a result of US markets have gotten much less aggressive (Philippon 2020). Within the first case, the shock is basically excellent news for Individuals, and transfers overseas is likely to be environment friendly. The second situation, in distinction, is a foul information shock for the US, and better transfers overseas make a foul state of affairs worse.
