Abstract
A growing body of evidence indicates that the U.S. economy has become less dynamic in recent years. This trend is evident in declining rates of gross job and worker flows as well as declining rates of entrepreneurship and young firm activity, and the trend is pervasive across industries, regions, and firm size classes. We describe the evidence on these changes in the U.S. economy by reviewing existing research. We then describe new empirical facts about the relationship between establishment-level productivity and employment growth, framing our results in terms of canonical models of firm dynamics and suggesting empirically testable potential explanations.

Television Role Models and Fertility: Evidence from a Natural Experiment
Peter Bönisch, Walter Hyll
SOEPpapers, Nr. 752,
Nr. 752,
2015
Abstract
In this paper we study the effect of television exposure on fertility. We exploit a natural experiment that took place in Germany after WWII. For topographical reasons, Western TV programs, which promoted one/no child families, could not be received in certain parts of East Germany. Using an IV approach, we find robust evidence that watching West German TV results in lower fertility. This conclusion is robust to alternative model specifications and data sets. Our results imply that individual fertility decisions are affected by role models or information about other ways of life promoted by media.

The Role of Entrepreneurship in US Job Creation and Economic Dynamism

Journal of Economic Perspectives,
Nr. 3,
2014
Abstract
An optimal pace of business dynamics—encompassing the processes of entry, exit, expansion, and contraction—would balance the benefits of productivity and economic growth against the costs to firms and workers associated with reallocation of productive resources. It is difficult to prescribe what the optimal pace should be, but evidence accumulating from multiple datasets and methodologies suggests that the rate of business startups and the pace of employment dynamism in the US economy has fallen over recent decades and that this downward trend accelerated after 2000. A critical factor in accounting for the decline in business dynamics is a lower rate of business startups and the related decreasing role of dynamic young businesses in the economy. For example, the share of US employment accounted for by young firms has declined by almost 30 percent over the last 30 years. These trends suggest that incentives for entrepreneurs to start new firms in the United States have diminished over time. We do not identify all the factors underlying these trends in this paper but offer some clues based on the empirical patterns for specific sectors and geographic regions.

Abstract
Grundschulschließungen werden kritisiert und gefürchtet. Besonders in peripheren Regionen verbindet sich mit der Aufgabe einer Schule vielfach die Sorge des demographischen Unterganges der Gemeinde infolge einer Abwanderung junger Eltern und ausbleibender Zuwanderung junger Familien. Sind Grundschul-schließungen aber tatsächlich Ursache einer Verschlechterung der Wanderungsbilanz?
Im vorliegenden Beitrag wird diese Fragestellung für die Familienwanderung zwischen Gemeinden Sachsen-Anhalts im Zeitraum von 1991 bis 2008 beantwortet. Die Untersuchung vergleicht im ersten Schritt die Wanderungsraten von Gemeinden mit unterschiedlicher Grundschulausstattung. Im zweiten Schritt wird die Querschnittsbetrachtung um eine Längsschnittanalyse ergänzt: Hier interessiert die Frage, ob sich das Wanderungsverhalten ändert, wenn die letzte Schule einer Gemeinde geschlossen wird. Der Analyse zufolge übt die schulische Infrastruktur von Gemeinden in Sachsen-Anhalt einen signifikanten Einfluss auf das Wanderungsverhalten der Familien mit jüngeren Kindern aus. So zeigt sich, dass nach der Schließung der letzten Grundschule die Zuzüge zurückgehen; überraschenderweise reduzieren sich jedoch auch die Fortzüge. Da sich beide Effekte gegenseitig gerade aufheben, ist eine Wirkung der Schließung per saldo jedoch nicht mehr erkennbar. Damit ist das Problem eines sich selbst verstärkenden Schrumpfungsprozesses zumindest mit Blick auf junge Familien empirisch nicht ersichtlich.

Effects of Entrepreneurship Education at Universities

Jena Economic Research Papers,
Nr. 25,
2012
Abstract
This study analyzes the impact of entrepreneurship education at universities on the intentions of students to become entrepreneurs or self-employed in the short-term (immediately after graduation) and in the long-term (five years after graduation). A difference-in-differences approach is applied that relates changes in entrepreneurial intentions to changes in the attendance of entrepreneurship classes in the same period. To account for a potential bias due to self-selection into entrepreneurship classes, only individuals having no prior entrepreneurial intentions are analyzed. Our results indicate a stimulating effect of entrepreneurship education on students’ intentions to become entrepreneurs or self-employed in the long-term but a discouraging effect on their intentions in the short-term. These results support the conjecture that entrepreneurship education provides more realistic perspectives on what it takes to be an entrepreneur, resulting in ‘sorting’. Overall, the results indicate that entrepreneurship education may improve the quality of labor market matches, the allocation of resources and talent, and increase social welfare. Not distinguishing between short- and long-term intentions may lead to misleading conclusions regarding the economic and social impact of entrepreneurship education.

Abstract
The paper subjects seven structural DSGE models, all used heavily by policymaking institutions, to discretionary fiscal stimulus shocks using seven different fiscal instruments, and compares the results to those of two prominent academic DSGE models. There is considerable agreement across models on both the absolute and relative sizes of different types of fiscal multipliers. The size of many multipliers is large, particularly for spending and targeted transfers. Fiscal policy is most effective if it has moderate persistence and if monetary policy is accommodative. Permanently higher spending or deficits imply significantly lower initial multipliers.

Human Capital and Fertility in Germany after 1990: Evidence from a Multi-Spell Model
Marco Sunder
IWH Discussion Papers,
Nr. 22,
2009
Abstract
We analyze the timing of birth of the first three children based on German panel
data (GSOEP) within a hazard rate framework. A random effects estimator is
used to accommodate correlation across spells. We consider the role of human
capital – approximated by a Mincer-type regression – and its gender-specific
effects on postponement of parenthood and possible recuperation at higherorder
births. An advantage of the use of panel data in this context consists in
its prospective nature, so that determinants of fertility can be measured when
at risk rather than ex-post, thus helping to reduce the risk of reverse causality.
The analysis finds evidence for strong recuperation effects, i.e., women with
greater human capital endowments follow, on average, a different birth history
trajectory, but with negligible curtailment of completed fertility.

The Transition to Post-industrial BMI Values among US Children
Marco Sunder, Ariane Breitfelder, John Komlos
American Journal of Human Biology,
2009
Abstract
The trend in the BMI values of US children has not been estimated very convincingly because of the absence of longitudinal data. Our objective is to estimate time series of BMI values by birth cohorts instead of measurement years. We use five regression models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 between 1941 and 2004. The increase in BMIZ values during the period considered was 1.3 (95% CI: 1.16; 1.44) among black girls, 0.8 for black boys, 0.7 for white boys, and 0.6 for white girls. This translates into an increase in BMI values of some 5.6, 3.3, 2.4, and 1.5 units, respectively. While the increase in BMI values started among the birth cohorts of the 1940s among black girls, the rate of increase tended to accelerate among all four ethnic/gender groups born in the mid-1950s to early-1960s. Some regional evidence leads to the conjecture that the spread of automobiles and radios affected the BMI values of boys already in the interwar period. We suppose that the changes in lifestyle associated with the labor saving technological developments of the 20th century are associated with the weight gains observed. The increased popularity of television viewing was most prominently associated with the contemporaneous acceleration in BMI gain. Am. J. Hum. Biol., 2009. © 2008 Wiley-Liss, Inc.

Evaluating the German (New Keynesian) Phillips Curve
Rolf Scheufele
IWH Discussion Papers,
Nr. 10,
2008
Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity where firms never re-optimize prices. This analysis also offers some explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.
