When Do Fiscal Rules Work? Institutional Quality and the Effectiveness of Fiscal Rules in the European Union
This paper finds that while fiscal rules effectively mitigate election-induced fiscal deterioration in Western EU member states, their success in Central and Eastern Europe is contingent upon high domestic institutional quality, particularly regarding the rule of law, corruption control, and democratic accountability.

Governments are made of people, and people are often driven by the desire to stay in power. In the world of economics, this creates a predictable pattern known as a political budget cycle. When an election is approaching, leaders face a powerful temptation to make the economy look better than it really is. They might cut taxes or increase spending to win votes, even if it means borrowing more money or running a larger deficit. This is not a new idea; it is a well-understood risk in how nations manage their money. To stop this, many countries, especially in the European Union, have created strict written rules. These are like speed limits for government spending, designed to force leaders to keep their finances in check no matter how close an election gets.
The European Union has built a massive system of these rules, applying similar laws to all its member states. On paper, a rule in one country looks very much like a rule in another. But the countries themselves are not the same. Some have long histories of stable courts, clean administration, and strong accountability. Others, particularly those in Central and Eastern Europe that joined the union more recently, are still building those same foundations. The big question for economists is whether a rule written on paper works the same way in every country. Does a strict spending limit actually stop a government from overspending before an election, or does it only work if the country has the right tools to enforce it? This is the puzzle a team of researchers set out to solve.
The researchers, Barbara Brix, Marianna Siničáková, and Anna Tykhonenko, looked at the financial records of all twenty-seven European Union member states over nearly thirty years, from 1995 to 2023. They wanted to see if the presence of strong fiscal rules actually changed what governments did during election years. They focused on the primary balance, which is a measure of how much money the government has left after paying for its daily operations but before paying interest on its debts. A drop in this number means the government is spending more than it earns. The team tracked when elections happened, how strong each country's fiscal rules were, and the overall quality of that country's institutions, such as how well its courts work and how much corruption exists.
When they analyzed the data, the first thing they found was that the temptation to spend before an election is real. Across the entire European Union, election years were consistently linked to a weakening of the government's finances. Leaders were indeed loosening their belts when voters were watching. However, the story changed when they looked at whether the strict rules actually stopped this behavior. The answer depended entirely on where the country was located and how well its institutions worked. In the older, Western European nations, the rules worked as intended. In these countries, the stronger the fiscal rules were, the less the government's finances deteriorated before an election. The rules acted as a real brake, preventing leaders from giving in to the pressure to overspend.
The picture was very different in Central and Eastern Europe. In these nations, the same strict rules did not seem to have the same effect. Even when these countries had strong written rules, their governments still tended to weaken their finances before elections. The rules were there, but they did not stop the spending. The researchers found that this difference was not just about geography or history. Instead, it was about the quality of the institutions that enforce the rules. They discovered that in countries where the rule of law is strong, corruption is low, and the government is accountable to its people, the fiscal rules successfully prevented election-year spending sprees. But in countries where these supporting systems were weaker, the rules existed on paper but failed to change behavior.
This finding suggests that writing a law is not the same as having a working system. A fiscal rule is like a sign on a road; it tells drivers the speed limit. But if there are no police to check for speeding, or if the courts do not punish those who break the law, the sign alone will not stop drivers from speeding. The researchers showed that for fiscal rules to work, they need a strong environment to back them up. In the European Union, this means that simply adopting the same set of rules across all member states is not enough to guarantee the same results. The effectiveness of the rules depends on the local capacity to enforce them. For the countries in Central and Eastern Europe, this implies that future progress in fiscal discipline may depend less on writing new rules and more on strengthening the institutions that make those rules matter. The study concludes that the success of economic governance is not automatic; it is conditional on the quality of the democracy and administration in which it operates.
