In the years after World War II, Western societies created systems of social security - the ‘Welfare State’ - and for a while it seemed as if they could do so without serious economic consequences. From a macro-economic point of view, they hoped to enjoy growth, full employment and low inflation. These indeed happened in the golden years 1950-1970. However, there arose the problem of stagflation around 1970, i.e. the combination of high unemployment, high inflation and stagnating growth. Around 1980, unemployment and inflation reached double digit values. Other economic indicators in the red were budget deficits, high interest rates, and the crowding out of private investments. Adjustment to these problems has been difficult and slow. The economic performance around 2004 is a major improvement from the worst episode, but the progress seems to be stagnating. The ongoing discussion in policy making circles during all these years is how the Welfare State arrangements are related to these economic problems, and what the proper policy reaction should be.
Welfare state economics differs from ‘traditional’ macro-economics in that there are more arrangements that protect individuals from insecurity and that entitle them to benefits. Welfare state economics however does not differ from ‘traditional’ macro-economics in the respect that the basic laws of economics cannot be changed. Generous as arrangements can be, people fundamentally still react to incentives. Welfare state arrangements tend to reduce the base of the economy of those participating in the workforce and they increase the burden on those. The welfare state also tends to generate more unemployment and inflation. While unemployment would ‘traditionally’ cause people to lose their income and thus to be more cautious with their wage demands, in the welfare state they receive an unemployment benefit and may continue tot insist on high wages. These points can readily be verified from comparing the results of the EU and US economies, where the EU is more of a welfare state and where the US has more traditional features.
Not surprisingly, there has been much debate about the sustainability of the welfare state. The US economy clearly is more dynamic and in many respects also more successful and innovative than the European economy. In this debate, a wide range of issues is discussed, from trade to investments, technology, monetary policy, migration, and so on. All these features indeed are very important for a balanced economic judgement. A common conclusion remains that employment plays a key role, as is for example witnessed by the OECD (1994) “Jobs Study”, the OECD Economic Studies 31 (2000), OECD (2003), to name a few. This conclusion actually is not so surprising, since the very definition of the welfare state suggests that it tries to protect people from the uncertainties of the job market rather than anything else.
Many people accept these days that Western economies have a problem with jobs with a low level of productivity and thus a low level of market-earned income. The United States tolerate more poverty while Europe sets its minimum wage much higher so that Europa has more unemployment. This problem with low productivity jobs finds various explanations, notably those of technology, globalisation and labour market inflexibility - or ‘welfare state sclerosis’. Policies based on these explanations have been enacted for some time now. For quite some time, in fact; while little is being achieved. It is proper that we pose the question: why is it that we don’t achieve much ? [34]
The novel analysis presented in these pages finds the problem and answer in taxes. [ [35] As noted, benefits have to be financed, and the tax arrangements have a key impact on incentives and costs. We will focus on the influence of taxes that runs via the labour market, both directly by ‘labour taxes’ and indirectly by ‘consumption taxes’ that also affect the cost of labour. The emphasis in our study is on dynamics where interactions have more time to take hold. The idea of this present study is that by proper management of tax dynamics, the economy could become more efficient, in both the EU and US alike, so that ultimately the drawbacks of a welfare state can find a better balance with its advantages.
Obviously, when this analysis is new, then it has not been recognised before, and then it has likely been missing in policy. And policy that was based on a wrong analysis, is likely to have been the cause of the very problem that it wanted to solve.
The emphasis on taxes does not mean that technology, international trade and labour market inflexibilities are irrelevant. It does not mean that we can throw away the current macro-economic models. On the contrary: the emphasis on taxes is only an amendment to the current models. The tax analysis would be meaningless without these current models. I myself participated in the construction of the CPB (1990) Athena model, a sectoral model of the Dutch economy with 7000 variables, and I would be the last one to suggest that only taxes matter !
Though the amendment sounds simple, there still are grounds to cover. Unemployment obviously has a much longer history than the current problem. Also, the Western track record on unemployment can only be understood when the record on inflation is taken into account too. A wrong diagnosis of the cause of unemployment would also have its effects via the anti-inflation policy of the monetary authorities.
