We present a model of a marriage market with positive assortative matching, where in equilibrium, the poorest women stay single. Couples have to decide on the number of children and spousal specialization in home production of public goods and child care. We then study how child care provision affects the equilibrium. Due to specialization in home production, the incentive to use child care is smaller for married mothers than for single mothers. We show that this increases the number of single mothers and the divorce rate. Using survey data from Germany, we present suggestive empirical evidence consistent with this finding.

It shows that building height limits lead to urban sprawl and higher emissions from commuting. On the other hand, aggregate housing consumption may decrease, which reduces emissions from residential energy use. A numerical model is used to evaluate whether total GHG emissions may be lower under building height restrictions. Welfare is not concave in the strictness of building height limits, so either no limit or a very strict one (depending on the strength of the externality) might maximize welfare. The paper discusses several extensions, such as congestion, endogenous transport mode choice, migration, and urban heat island effect. (C) 2016 Elsevier B.V.

In the baseline simulation, total pollution falls by 0.4\%, as decreasing emissions from transport are partly offset by rising residential emissions. A second counterfactual compares a city with and without public transit. This large investment decreases pollution by 1.7\%. When jobs are decentralized, emissions fall by 0.5\% in the first and by 3\% in the second counterfactual.}, language = {en} } @incollection{Borck2023, author = {Borck, Rainald}, title = {Energy policies, agglomeration, and pollution}, series = {Handbook of labor, human resources and population economics}, booktitle = {Handbook of labor, human resources and population economics}, editor = {Zimmermann, Klaus F.}, publisher = {Springer International Publishing}, address = {Cham}, isbn = {978-3-319-57365-6}, doi = {10.1007/978-3-319-57365-6_421-1}, pages = {1 -- 15}, year = {2023}, abstract = {This chapter reviews the interplay of agglomeration and pollution as well as the effect of energy policies on pollution in an urban context. It starts by describing the effect of agglomeration on pollution.

The chapter discusses the implications for optimal city size. Conversely, urban pollution tends to discourage agglomeration if larger cities are more exposed to pollution.

We then analyze the effects of these taxes on urban spatial structure, showing that they reduce the extent of commuting and the level of housing consumption while increasing building heights, generating a more-compact city with a lower level of emissions per capita.}, language = {en} } @article{BorckFossenFreieretal.2015, author = {Borck, Rainald and Fossen, Frank M. and Freier, Ronny and Martin, Thorsten}, title = {Race to the debt trap? - Spatial econometric evidence on debt in German municipalities}, series = {Regional science and urban economics}, volume = {53}, journal = {Regional science and urban economics}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0166-0462}, doi = {10.1016/j.regsciurbeco.2015.04.003}, pages = {20 -- 37}, year = {2015}, abstract = {Through an intertemporal budget constraint, jurisdictions may gain advantages in tax and spending competition by 'competing' on debt. While the existing spatial econometric literature focuses on tax and spending competition, very little is known about spatial interaction via public debt. If jurisdictions compete for mobile capital to finance public spending, they may compete in debt levels as well as taxes. We use a theoretical model to derive the reaction of jurisdictions' debt levels to their neighbors' debts. We then estimate the spatial interdependence of public debt among German municipalities using a panel on municipalities in the two largest German states from 1999 to 2006. We find significant and robust interaction effects between debt levels of neighboring municipalities, which we compare to spatial tax and spending interactions. The results indicate that a municipality increases its per capita debt by 16-33 Euro as a reaction to an increase of 100 Euro in neighboring municipalities. (C) 2015 Elsevier B.V.
