This paper analyzes municipal expenditures in the light of horizontal fiscal interactions. I investigate total expenditures and a set of non-earmarked expenditure subcategories in the largest German federal state, North Rhine-Westphalia (NRW). The empirical analysis is based on a Spatial Durbin Model in a panel for the years 2009-2015. Using a two-regime spatial matrix, I also examine the impact of agglomeration on the intensity of public expenditure interactions, thus testing the hypothesis that an agglomerated region can decrease the amount of public goods without losing mobile factors to the periphery. The findings indicate that significant municipal expenditure interaction effects do exist. The reaction functions also vary for different expenditure subcategories. Unlike spillover effects and fiscal competition, yardstick competition is an insignificant source of potential interactions. Expenditure interaction is fiercer if there is less agglomeration in a municipality. Urbanized and populous municipalities appear to benefit from agglomeration economies, a fact that enables them to spend less. Robustness checks confirm the findings.

This paper aims to quantify the municipal tax revenue effects of built-up area increases. The assumed existence of these effects is one of the key reasons for ongoing land consumption on the side of the municipalities. Some previous case studies however suggested that these effects might be not large enough especially in rural municipalities and would thus make land development not profitable. We estimate the effect of built-up industrial and commercial (BIC) area change on the business tax revenues in cross-sectional instrumental variable (IV) estimations. Based on detailed data for Bavaria, we find a significant and positive tax revenue effect of an increase in municipal BIC area. There exist strong differences in the size of this effect between urban and rural municipalities. The largest effects are generated by the BIC area in the large cities and become substantially smaller when these are dropped from the sample. Based on these findings, we reflect on the tradable planning permits (TPP) scheme recently discussed in the land use literature in the context of policies aiming to limit land consumption. Furthermore, we relate our estimates to the average municipal costs for land development and execute a number of robustness checks.

We investigate how lump-sum equalization transfers affect expenditures and taxes in the municipalities of the largest German state North Rhine-Westphalia. In general, those general-purpose transfers cannot be treated as exogenous variables. Thus, for the identification of causal effects, two exogenous adjustments in the transfer allocation formula are used as instrumental variables. Findings suggest the existence of the “flypaper effect” – municipalities use transfers to increase expenditures but do not reduce tax rates. Extra money from transfers is mainly used to finance social expenditures and public facilities. A set of robustness checks, including a spatial dependence model, confirm the results.

This paper examines the distributional effects of international trade in a general equilibrium model with heterogeneous agents and a welfare state redistributing income. The redistribution scheme is financed by a progressive income tax and gives the same absolute transfer to all individuals. Ceteris paribus, international trade leads to an increase in income per capita but also to higher income inequality on two fronts. Inter-group inequality between managers and workers increases, and intra-group inequality within the group of managers goes up as well. We show that for constant tax rates, there is an endogenous increase in the size of the welfare state that works against the increase in inequality, yet cannot offset it. The paper also sheds light on the conditions under which trade can actually lead to a Pareto improvement.

Left-hand drive (LHD) vehicles share higher road accident risks under left-hand traffic because of blind spot areas. Due to low import prices, the number of wrong-hand drive vehicles skyrockets in emerging countries like Georgia, Kyrgyzstan and Russia. I identify the causal effect of wrong-hand drive vehicles on road safety employing a new “backward version” of the synthetic control method. Sweden switched from left-hand to right-hand traffic in 1967. Before 1967, however, almost all Swedish vehicles were LHD for reasons of international trade and Swedish customer demand. I match on accident figures in the period after 1967, when both Sweden and other European countries drove on the right and used LHD vehicles. Results show that right-hand traffic decreased road fatality, injury and accident risk in Sweden by approximately 30 percent. An earlier switch would have saved more than 4,000 lives between 1953 and 1966.

The resource curse hypothesis suggests that resource-rich countries show lower economic growth rates compared to resource-poor countries. We add to this literature by providing empirical evidence on a new transmission channel of the resource curse, namely, the negative effect of rents on the quality of education. The cross-country analysis for more than 70 countries shows a significantly positive effect of oil rents on the quantity of education measured by government spending on primary and secondary education. Hence, the underspending hypothesis championed by Gylfason (2001) no longer holds with newer data. However, we find a robust and negative effect of oil rents dependency on the current objective and subjective indicators of quality of education, controlling for a set of other drivers of education quality and regional dummies. Despite spending significant shares of GDP on education, oil-rich countries still suffer from an insufficient quality of primary and secondary education, which may hamper their growth potentials. The significant negative effect of oil rents dependency on education quality can be explained by both the demand (e.g., skill acquisition) and supply (e.g., teacher quality) side channels.

Ethiopia is one of the most vulnerable countries to climate change. This is because its important economic sector, agriculture, is virtually rain-fed. The role of the sector in the current economic structure and the potency of the anticipated biophysical impacts of climate change necessitates proactive adaptation in agriculture. This, however, breeds questions of adaptation costs and adaptation finance. This study attempts to derive plausible range of planned adaptation costs in agriculture along with their economy-wide and regional effects in Ethiopia. It also assess the economy-wide and regional effects of the likely options available to a government of a least-developed country to finance adaptation in agriculture. The results show that planned public adaptation in agriculture puts pressure on government surplus, impedes on manufacturing and private services, and GDP of urbanized regions. As such, it may strain the current macroeconomic endeavors of the country which puts government driven structural transformation and reducing fiscal deficit relative to GDP at the center. Government of Ethiopia may reconcile this by laying out incentives to urban agriculture and private investment in agriculture. Besides, foreign support in the form of biotechnology transfer and debt-relief may help to control the side effects of grants on foreign exchange market and trade balance.

Quantifying the economic effects of climate change is a crucial step for planning adaptation in developing countries. This study assesses the economy-wide and regional effects of climate change induced productivity and labor supply shocks in agriculture in Ethiopia. The study shows, in worst case scenario, the effects on national GDP may add up to -8% with uneven regional effects ranging from -10% in agrarian regions (e.g. Amhara) to +2.5% in urbanized regions (e.g. Addis Ababa). Cost-free exogenous structural change scenarios in labor markets and transaction costs may offset about 20-30% of the ripple effects of climate change. Therefore, the ongoing structural transformation in the country may underpin the resilience of the economy to climate change. Nevertheless, given the role of agriculture in the current economic structure of the country and the potency of biophysical impacts of climate change, adaptation in the sector is indispensable. Otherwise, climate change may hamper economic progress of the country, and make rural livelihood unpredictable.

This paper investigates the effects of international trade in a general equilibrium model with heterogeneous firms where a welfare state redistributes income. We look at a very stylised progressive non-distortionary redistribution scheme. We show that for a given tax rate international trade increases income per capita, but also leads to higher income inequality. Two aspects of income inequality are examined. First, inter-group inequality between managers and workers is considered. Second, intra-group inequality within the group of managers is investigated. For a given tax rate the size of the welfare state and therefore the transfer per capita increases when going from autarky to trade. This second-round effect counteracts the primary increase in inequality, yet cannot outweigh it. Since the redistribution scheme is non-distortionary, it is possible to decrease trade-induced inequality by increasing the tax rate without jeopardising the gains from trade.

We investigate the effect of general-purpose transfers on different expenditure categories and tax rates in the municipalities of Saxony (eastern Germany) and North Rhine-Westphalia (western Germany). Findings from the panel data analysis suggest the existence of the “flypaper effect” – municipalities use transfers to increase expenditures but do not reduce taxes. For most expenditure subcategories the estimated coefficients are alike, suggesting similarity of spending priorities in the two federal states despite the differences in the transfer dependency. Targeted support of eastern municipalities could potentially explain few identified differences in the spending behavior.
