On the Analytics of the Dynamic Laffer Curve
- 2000
-
Reports (other academic/artistic)abstract
- In this paper, we analyze government budget balance within a simple model of endogenous growth. For the AK model, simple analytical conditions for a tax cut to be self-financing can be derived. The critical variable is not the tax rate per se, but the "transfer-adjusted tax rate". We discuss some conceptual issues in dynamic revenue analysis, and we explain why previous studies have arrived at seemingly contradictory results. Finally, we perform an empirical study of the transfer-adjusted tax rates of the OECD countries to see which country has the highest potential for fiscal improvements; it turns out that only a few countries have any potential for such "dynamic scoring".

Gender and Overconfidence
- 2004
-
Reports (other academic/artistic)abstract
- Do males differ from females in terms of self-confidence? The structure of the Economics I exam at Stockholm University provides an opportunity to shed some light in this question. By answering an extra, optional question, the students can aim for a higher mark. We find a clear gender difference in that male students are inclined than female students to take this opportunity. This difference in self-assessment is more pronounced among younger than among older students.

The Effects on Sick Leave of Changes in the Sickness Insurance System
- 2001
-
Reports (other academic/artistic)abstract
- In order to get a more complete picture of how labor supply is affected by economic incentives, the effects on absenteeism and not just on contracted hours should be taken into account. In particular, the effects on absenteeism due to sick leave can be considerable. In this paper we examine whether the level of sick leave compensation affects sick leave behavior. Using time-series data for Sweden spanning a long period (1955-99) with numerous changes of the compensation level, we generally find strong effects of the expected sign. Reforms implying more generous compensation for sick leave tend to be associated with permament increases in total sick leave per person employed and vice versa. These findings are reinforced in a panel study covering the 1983-91 period.

The Gains from Pension Reform
- 2002
-
Reports (other academic/artistic)abstract
- We classify social security pension systems in three dimensions: actuarial versus non-actuarial, funded versus unfunded, and defined-benefit versus defined contribution systems. Recent pension reforms are discussed in terms of these dimensions. Shifting to a more actuarial system reduces labor-market distortions, although limiting the scope for redistribution. Shifting to a funded system may increase saving, redistribute income to future generations and distort contermporary labor supply. A partial shift to a funded system helps individuals diversify their pension assets. A shift from a defined-benefit to a defined-contribution system means that income risk will be shifted from workers to pensioners.

Reconstruction of equivalent currents using a near-field data transformation - with radome applications
- 2004
-
Reports (other academic/artistic)abstract
- Knowledge of the current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to its equivalent current distribution on a surface, i.e., the radome, is analyzed. The transformation is based on the surface integral representation that relates the equivalent currents to the near-field data. The presence of axial symmetry enables usage of the fast Fourier transform (FFT) to reduce the computational complexity. Furthermore, the problem is regularized using the singular value decomposition (SVD). Both synthetic and measured data are used to verify the method. The quantity of data is vast since the height of the radome corresponds to 29 − 43wavelengths in the frequency interval 8.0 − 12.0 GHz. It is shown that the method gives an accurate description of the field radiated from an antenna, on a surface enclosing it. Moreover, defects on the radome, not localized in the measured near field, are focused and detectable on the radome surface.

Five Fallacies in the Social Security Debate
- 2000
-
Reports (other academic/artistic)abstract
- This paper discusses five examples of the conventional wisdom that has often been expressed in the social security debate, even among academic economists. These are: 1. The major problem in most social security systems is that of demography: people simply live too long. 2. Disregarding the issue of demography, a Pay-As-You-Go system is inferior to a fully funded system since the former usually has a lower rate of return. 3. Disregarding the porfolio aspect (which might favor a PAYG system), a funded system dominates a PAYG system in a world of certainty. 4. The social security system is a suitable isntrument for intergenerational risk-sharing. 5. The government is a safe and reliable provider of insurance.
