Optimal tax progression : does it matter whether wage bargaining is decentralized or centralized?
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- We study how the optimal use of labor income tax progression depends on whether the wage bargaining system is decentralized or centralized. Assuming a nonlinear labor income tax and an unrestricted profit tax, we show that a Utilitarian government is able to implement the first best resource allocation with a zero marginal labor income tax rate under decentralized wage bargaining, whereas centralized bargaining typically implies a progressive tax as well as unemployment. However, if the government and a (central) wage-setter bargain over wage formation and public policy, the resulting equilibrium is characterized by full employment and a zero marginal tax rate.

Social identity, education and tax policy
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This paper analyzes the implications of social identity and self-categorization in the context of optimal redistributive income taxation. A two-type model is supplemented by an assumption that individuals select themselves into social categories, in which norms are formed and education effort choices partly depend on these norms. Optimal tax policy is analyzed under two different assumptions about the social objective function: a welfarist objective based on consumer preferences and a paternalist objective that does not reflect the consumer preference for social identity. We show how the welfarist government implements a tax policy to internalize the externalities arising from social norms, while the paternalist government uses tax policy to make individuals behave as if their preferences for social identity were absent.

- BACKGROUND:During ultrasound examination, tricuspid regurgitation may be absent or gives a signal that is not reliable for the estimation of systolic pulmonary pressure. The aim of this study was to evaluate the usefulness of acceleration time (AT) from the right ventricular outflow tract (RVOT) as an estimation of the trans-tricuspid valve gradient (TTVG) and to investigate the correlation between estimated and invasive pulmonary vascular resistance (PVR).METHODS:The AT was correlated to the TTVG measured with routine standard echocardiography in 121 patients. In a subgroup of 29 patients, systolic pulmonary pressure (SPAP) and mean pulmonary arterial pressure (MPAP) were obtained from recent right heart catheterization (RHC).RESULTS:We found no significant correlation between the estimation of right atrial pressure (RAP) by echocardiography and the RAP obtained by RHC. Estimated SPAP (TTGV + RAP mean from RHC) showed a good linear relation to invasively measured SPAP. TTVG and AT showed a non-linear relation, similar to SPAP and MPAP measured by catheterization and AT. For detection of SPAP above 38 mmHg a cut-off for AT of 100 ms resulted in a sensitivity of 89% and a specificity of 84%. For detection of MPAP above 25 mmHg a cut-off for AT of 100 ms resulted in similar sensitivity and specificity. Invasive PVR and the ratio of TTVG and the time velocity integral of the RVOT (TVI RVOT ) had a strong linear relation.CONCLUSIONS: Our study confirms that AT appears to be useful for the evaluation of pulmonary hypertension. In high risk patients, an AT of less than 100 ms indicates a high probability of pulmonary hypertension. Furthermore, PVR estimation by ultrasound seems preferably be done by using the ratio of TTVG and TVI RVOT.

Amalgamation impacts on local growth : Are voluntary amalgamations more efficient than compulsory amalgamations?
- 2010

Ingår i: Canadian journal of regional science. ; 33:1, s. 57-70

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this paper is to analyse amalgamation impacts on local population and income growth as well as whether voluntary amalgamations are more efficient compared to compulsory amalgamations. The empirical analysis is based on data for 1,005 Swedish municipalities for the period 1953-1959, i.e. a six-year period after the 1952 municipal reform. The reform was state imposed and 66 percent of the newly formed municipalities were amalgamated on a compulsory basis. The results show that amalgamations had a positive effect on population growth in small municipalities. The main finding in the paper is that municipalities formed on a voluntary basis had higher population growth compared to municipalities formed on a compulsory basis. One conclusion is that local opinions are important to consider when forming a new local government structure.
