The mantra in Brussels and throughout Europe nowadays is that investment holds the key to economic recovery. The lynchpin of the new European Commission's economic strategy is its recently unveiled plan to increase investment by euro 315 billion ($390 billion) over the next three years. But the commission's proposal is misguided, both in terms of its emphasis on investment and its proposed financing structure.
The commission's plan, the signature initiative of President Jean-Claude Juncker at the start of his term, comes as no surprise. With the euro zone stuck in a seemingly never-ending recession, the idea that growth-enhancing investment is crucial for a sustainable recovery has become deeply entrenched in public discourse. The underlying assumption is that more investment is always better, because it increases the capital stock and, thus, output.
This is not necessarily the case in Europe at the moment. The European Union (EU) authorities (and many others) argue that Europe - particularly the euro zone - suffers from an "investment gap". The smoking gun is supposedly the euro 400-billion annual shortfall relative to 2007.
But the comparison is misleading, because 2007 was the peak of a credit bubble that led to a lot of wasteful investment. The commission recognises this in its supporting documentation for the Juncker package, in which it argues that the pre-credit-boom years should be used as the benchmark for desirable investment levels today. According to that measure, the investment gap is only half as large.
Unfortunately, even the pre-boom years are not a good guide for today's European economy, because something fundamental has changed more quickly than is typically recognised: Europe's demographic trends.
The euro zone's working-age population had been growing until 2005, but it will fall from 2015 onward. Given that productivity has not been picking up, fewer workers mean significantly lower potential growth rates. And a lower growth rate implies that less investment is needed to maintain the capital-output ratio.
If the euro zone maintained its investment rate at the level of the pre-boom years, there would soon be much more capital relative to the size of the economy. One might be tempted to say: so what? More capital is always good.
An ever-increasing capital stock relative to output, however, means ever-lower returns to capital and, thus, ever more non-performing loans in the banking sector over time. Given the weak state of Europe's banking system, accumulating too much capital is not a luxury that the EU can afford.
Even setting aside the question of whether more is always better, what can the Juncker plan do to have a positive short-run impact on aggregate investment?
Academic research on the determinants of investment has generally concluded that the key variable is growth (or expectations of growth), and that interest rates play at most a secondary role. One immediate implication of this, of course, is that monetary policy is unlikely to have a strong impact on investment.
Indeed, the market signal is clear: at present, there is no shortage of funding available in most of the EU. The countries on the euro-zone periphery, where credit might still be scarce, account for less than one-quarter of Europe's economy. So a lack of funding is not the reason that investment remains weak.
The Juncker plan is supposed to unlock, with euro 21 billion in EU funding, projects worth 15 times as much (euro 315 billion). That sounds far-fetched. Europe's banking system already has more than euro 1 trillion in capital. The addition of euro 21 billion, in the form of guarantees from the EU Budget, is unlikely to have a significant impact on banks' willingness to finance investment.
The Juncker plan targets, in particular, infrastructure projects, which are often riskier than other investments. But these risks usually are not financial; they reflect potential political and regulatory barriers at the national level. These problems cannot be solved by a guarantee from the EU Budget (which in any case could not be larger than 1/15th of the value of the project).
The reason why there still is no good interconnection between the Spanish and the French power grids is not a lack of financing, but the unwillingness of monopolies on both sides of the border to open their markets. Many rail and road projects are also proceeding slowly, owing to local opposition, not a lack of financing. These are the real barriers to infrastructure investment in Europe. Large European companies can easily obtain financing at near-zero interest rates.
Calling for more investment is superficially always attractive. But there are fundamental reasons to believe that the euro zone's investment rate will remain permanently depressed. The often-invoked investment gap is mostly a result of wishful thinking, and the remaining barriers to investment have little to do with a lack of financing.
Economic performance in the United States and the United Kingdom holds an important lesson for the euro zone. Both economies' recoveries have been driven largely by a pick-up in consumption on the back of stronger household balance sheets, especially in the United States. The revival of investment has followed the resumption of consumption growth. If European policymakers are serious about economic recovery, they should focus on consumption, not investment.
