The outbreak of the financial crisis in 2008 has had significant effects on economic activity, unemployment, and public finances for all European countries. However, European economies do not form a homogenous region, and any serious analysis of macroeconomic imbalances in Europe must account for the fact that different economic and political models and circumstances operate across the continent. This book focuses on the Nordic countries which have a relatively good record of undertaking fiscal and structural reforms after their own financial and debt crises in the 1980s and 1990s.

The welfare state is not merely a stand-in for missing markets; it can do a whole lot more. When generations overlap and the young must borrow to make educational investments, a dynamically-efficient welfare state, by taxing the middle-aged and offering a compensatory old-age pension, can generate higher long-run human capital and welfare compared to laissez faire. Along the transition, no generation is hurt and some are better off. If an intergenerational human capital externality is present, unfunded pensions can be gradually phased out entirely. Public pension reform can be rationalized on efficiency grounds without relying on political-economy concerns or aging.

Recent debates have suggested that taxation is very detrimental to labour force participation and employment. However, some countries - notably the Scandinavian - stand out as contradictions to this view since they have managed to sustain high labour force participation rate despite high tax rates and a generous social safety net. This either refutes the standard incentive argument or leave the Scandinavian countries as a puzzle. This paper argues that both the standard view and the Scandinavian experience can be reconciled when taking into account both the pecuniary and non-pecuniary incentives build into the social safety net. The social safety net in the Scandinavian countries is at the same time both generous and employment conditioned. It is shown that these conditionalities can make high labour force participation consistent with a high marginal effective taxation of labour, and that it on the margin lowers the marginal costs of public funds. Such employment conditionalities make it possible to achieve distributional objectives without jeopardizing the incentive structure.

This paper revisits the role played by myopia in generating a theoretical rationale for pay-as-you-go social security in dynamically efficient economies. Contrary to received wisdom, if the real interest rate is exogenously fixed, enough myopia may justify public pensions but never alongside positive private savings. With sufficient myopia, co-existence of positive optimal pensions and positive private saving is possible if the real interest rate on saving evolves endogenously, as in a model with a neoclassical technology.

It is widely perceived that globalization is a threat to tax financed public sector activities. The argument is that public activities (public consumption and transfers) financed by income taxes may distort labour markets and cause higher wages and thus a loss of competitiveness. If the importance of the latter effect is reinforced by globalization, it is inferred that the marginal costs of public funds increase and a retrenchment of the public sector follows. We consider this issue in a Ricardian trade model in which production and specialization structures are endogenous. Even though income taxation unambiguously worsens wage competitiveness, it does not follow that tax distortions or marginal costs of public funds increase with product market integration. The reason is that gains from trade tend to reduce both. Moreover, non-cooperative fiscal policies do not have a bias towards retrenchment due to a positive terms of trade effect from taxation.

This paper analyses two reasons why inflation may interfere with price adjustment so as to create inefficiencies in resource allocation at low rates of inflation. The first argument is that the higher the rate of inflation the lower the likelihood that downward nominal rigidities are binding (the Tobin argument) which implies a non-linear Phillips-curve. The second argument is that low inflation strengthens nominal price rigidities and thus impairs the flexibility of the price system resulting in a less efficient resource allocation. It is argued that inflation can be too low from a welfare point of view due to the presence of nominal rigidities, but the quantitative importance is an open question. Klassifikation:
