Shrinking due to corpulence? BMI in childhood predicts subsequent linear growth among US children and youth, 1963-1970

Abstract
While the USA is one of the most opulent countries, its population is not among the tallest but is among the most corpulent. This short report investigates the association between body mass index in childhood and subsequent change in height-for-age at the individual level, based on data from the National Health Examination Study (1963-1970). A sub-sample of participants in this survey was measured twice at intervals between 2.3 and 4.4 years, and assessed bone age can be used to account for differences in maturation at baseline. Regression results indicate that a BMI-for-age above the 85th percentile is associated with a reduction in growth by 0.03-0.06 height-for-age standard deviations per year, or roughly 1 cm within 4 years. An inefficiently high nutritional status in childhood may thus jeopardize subsequent linear growth. However, the trans-Atlantic height gap is considerably larger than what this empirical relationship could predict.

Where enterprises lead, people follow? Links between migration and FDI in Germany

Abstract
Standard neoclassical models of economic integration are based on the assumptions that capital and labor are substitutes and that the geography of factor market integration does not matter. Yet, these two assumptions are violated if agglomeration forces among factors from specific source countries are at work. Agglomeration implies that factors behave as complements and that the country of origin matters. This paper analyzes agglomeration between capital and labor empirically. We use state-level German data to answer the question whether and how migration and foreign direct investment (FDI) are linked. Stocks of inward FDI and of immigrants have similar determinants, and the geography of factor market integration matters. There are higher stocks of inward FDI in German states hosting a large foreign population from the same country of origin. This agglomeration effect is confined to higher-income source countries.

Explaining Regional Disparities in Housing Prices across German Districts

Abstract
Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.
