The reforms affected economic, educational, and social policies, ranging from the introduction of a universal child allowance to major changes in its labour market regulations and tax rules. From an economic policy perspective, the most significant reform package was implemented in January 2022. It was composed of a huge increase in Montenegro's statutory minimum wage, alongside a new income tax regime and the abolishment of mandatory health insurance contributions. According to the Government, the reform package aimed at increasing the living standards of citizens and promoting a more sustainable and inclusive growth model. This report evaluates the conjoint impact of this reform package.}, language = {en} } @techreport{BeckerBusleiGeyeretal., type = {Working Paper}, author = {Becker, Sebastian and Buslei, Hermann and Geyer, Johannes and Haan, Peter}, title = {The effect of pension wealth on employment}, edition = {No. 9}, doi = {10.48462/opus4-4702}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:b1570-opus4-47027}, pages = {49}, abstract = {This study provides novel evidence about the pension wealth elasticity of employment. For the identification we exploit reform-induced variation of pension wealth that is related to the number of children but which does not affect the implicit tax rate of employment. We use a difference-in-differences estimator based on administrative data from the German pension insurance and find that, on average, the negative employment effect of pension wealth is significant and economically important. Heterogeneity analyses document a strong age pattern showing that the employment effects are driven by behavioral responses of women close to retirement. The age pattern is partly explained by the positive effect of pension wealth on disability pensions after the age of 60.}, language = {en} } @techreport{HaanSunSundeetal., type = {Working Paper}, author = {Haan, Peter and Sun, Chen and Sunde, Uwe and Weizs{\"a}cker, Georg}, title = {Non-Additivity of Subjective Expectations over Different Time Intervals}, series = {Berlin School of Economics Discussion Papers}, journal = {Berlin School of Economics Discussion Papers}, edition = {No. 4}, doi = {10.48462/opus4-4660}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:b1570-opus4-46602}, pages = {38}, abstract = {We examine the additivity of stock-market expectations over different time intervals. When asked about a ten-year interval, survey respondents expect a stock-price change that is not equal to, but closer to zero than, the sum of their expectations over two shorter time intervals that cover the same ten years. Such sub-additivity is irrational in that it cannot stem from aggregating short-term expectations. Model estimates show that the pattern is consistent with a time perception where shorter time intervals have a proportionally larger weight. We also find that the respondents' degree of additivity is correlated with making larger financial investments.}, language = {en} } @techreport{HaanProwse, type = {Working Paper}, author = {Haan, Peter and Prowse, Victoria}, title = {The Heterogeneous Effects of Social Assistance and Unemployment Insurance: Evidence from a Life-Cycle Model of Family Labor Supply and Savings}, series = {Berlin School of Economics Discussion Papers}, journal = {Berlin School of Economics Discussion Papers}, edition = {No. 20}, doi = {10.48462/opus4-5012}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:b1570-opus4-50128}, pages = {87}, abstract = {We empirically analyze the heterogeneous welfare effects of unemployment insurance and social assistance. We estimate a structural life-cycle model of singles' and married couples' labor supply and savings decisions. The model includes heterogeneity by age, education, wealth, sex and household composition. In aggregate, social assistance dominates unemployment insurance; however, the opposite holds true for married men, whose leisure time declines more than that of their spouses when unemployment insurance is reduced. A revenue-neutral rebalancing of social support away from unemployment insurance and toward social assistance increases aggregate welfare. Income pooling in married households decreases the welfare value of social assistance.}, language = {en} } @techreport{HaanSantonjaZaklan, type = {Working Paper}, author = {Haan, Peter and Santonja, Adri{\´a}n and Zaklan, Aleksandar}, title = {Effectiveness and Heterogeneous Effects of Purchase Grants for Electric Vehicles}, edition = {No. 11}, doi = {10.48462/opus4-4761}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:b1570-opus4-47610}, pages = {35}, abstract = {We evaluate German purchase subsidies for battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) using data on new vehicle registrations in Germany during 2015-2022.

The program was cost-ineffective, as only 40\% of BEV and 25\% of PHEV registrations were subsidy-induced, and had strong distributional effects, with greater uptake in wealthier and greener counties. The implied abatement cost of 870 euro per ton of CO2 for BEVs and 2,470 euro for PHEVs suggests that subsidies to PHEVs were especially cost-ineffective.}, language = {en} } @techreport{HaanKemptnerProwseetal., type = {Working Paper}, author = {Haan, Peter and Kemptner, Daniel and Prowse, Victoria and Schaller, Maximilian}, title = {Insurance, Redistribution, and the Inequality of Lifetime Income}, series = {Berlin School of Economics Discussion Papers}, journal = {Berlin School of Economics Discussion Papers}, edition = {No. 28}, doi = {10.48462/opus4-5112}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:b1570-opus4-51126}, pages = {70}, abstract = {Individuals vary considerably in how much they earn during their lifetimes. This study examines the role of the tax-and-transfer system in mitigating such inequalities, which could otherwise lead to disparities in living standards.

Additionally, the system insures against 48\% of lifetime earnings risk. Implementing a lifetime tax reform linking annual taxes to previous employment could improve the system's insurance capabilities, albeit at the cost of a lower employment rate.}, language = {en} }
