Former prime minister of Poland and former Director of the European Department of the International Monetary Fund, is President of the National Bank of Poland.
The European Union's new member states from Central and Eastern Europe are required to join the eurozone as part of their accession agreements. But deciding when to adopt the euro is a matter of heated debate.
At stake is not just an economic calculation, but also a judgment about the outlook of the single currency itself. For many, the benefits of membership have diminished since the financial crisis, and prospective members, such as Poland, can derive maximum advantage from joining only if they are clear about the economic conditions that must first prevail in their own countries.
The formal criteria for entry are contained in the 1992 Maastricht Treaty, which sets targets for government debt, budget deficits, inflation, interest rates, and exchange rates. But merely hitting these targets (or, worse, just approaching them) at any given point in time has proved to be an inadequate foundation for membership. Indeed, the malleability of the Maastricht criteria has caused many of the eurozone's problems. As long as eurozone debts continue to rise and member economies diverge rather than converge, prospective members should also be stress-tested to see if they can withstand external shocks and sustain the membership criteria over the long term.
Before Poland decides to share a currency with its main trading partners, it should consider three vital economic conditions: its international competitiveness, the flexibility of its labor market, and the health of its public finances.
Poland's export markets are growing steadily. But this is not because the country trades mainly with other dynamic emerging economies, or because there is huge global demand for uniquely Polish products. Rather, Poland simply combines low costs (including wages) and high-quality production. For this reason, Poland is sometimes called the "China of Europe."
But competitiveness based on cost, rather than brand value or innovation, makes the Polish economy vulnerable. Poland lacks the deeply rooted competitiveness of, say, Germany, the Netherlands, Austria, Sweden, or Switzerland. Polish exports are sold under non-Polish names (Italian for shoes, for example, or English for clothing). Its machinery exports are part of larger multinational networks run by German, Dutch, or other global companies. And Poland's cost advantage would disappear if the z?oty were to strengthen sharply.
Although Polish companies are working hard to build brands abroad, this can take decades. In the meantime, the country must be careful about joining the exchange rate mechanism (ERM II) - the narrow band within which applicant currencies must operate for at least two years prior to adopting the euro. Doing so could cause the z?oty to strengthen, as it did to the Slovak koruna, and wipe out Poland's competitive advantage.
Another important aspect of Poland's competitiveness is its flexible labor market. One in four employees is on a fixed-term contract or self-employed. A quarter of the typical Polish wage comprises variable elements, making it easy to freeze, or even lower, compensation during tougher economic times. This means that firms can hire workers on short-term contracts when they are unsure of the business outlook; more generally, such flexibility helps the economy withstand external shocks.
But flexible labor markets have disadvantages, too. Companies tend not to invest in talent or develop new skills, and the quality of existing skills can suffer. In the longer run, flexible labor markets also increase structural unemployment and fuel the informal economy.
Furthermore, shortages in Poland's residential rental market restrict workers' ability to move to where the jobs are. Arguably, Poland's labor market is more akin to Spain's than that of Scandinavia, where generous social protection allows for extensive employee training.
Finally, Poland needs sound public finances - that is, fiscal space for automatic stabilizers during economic crises. By saving money for hard times, the government can implement countercyclical measures, while ensuring stable finances throughout the economic cycle.
Such a policy was successfully implemented in 2009 and 2010, but the government lacked the funds it needed when economic conditions subsequently deteriorated. Sound public finances require not only low public debt, but also appropriate budgetary policy, which includes cutting spending (or raising taxes) during boom times, not during downturns, as was recently the case.
Broad-based competitiveness, truly flexible labor markets, and prudent budgeting are not beyond Poland's reach. In each case, there are other national examples to emulate: Switzerland's competitiveness, Denmark's labor markets, and Estonia's public finances, for example. Before Poland joins the eurozone, its economic policy should be directed toward these three criteria of long-term economic success.
