Productivity Growth, Investment, and Secular Stagnation
16 November 2015, Guido Baldi
Roundup 83

In many advanced economies, the economic recovery from the financial crisis has been sluggish. In light of these developments, it has been argued by various economists that economic growth per capita has already been on a downward trend since the 1980s. Studies suggest that this is largely due to low productivity growth. While factors of production such as labor and capital are being used more productively than ever, growth has been slow in the past years by historical standards. In parallel to this low productivity growth, corporate investment in many countries has been subdued, especially (...)

Increasing Father Involvement in Child Care: What Do We Know about Effects on Child Development?
29 September 2015, Pia S. Schober
Roundup 79

The time fathers spend and the activities they perform with children have risen continuously in most Western countries. Increasing father involvement in child care has also been an explicit policy objective with many European countries implementing individual parental leave entitlements for fathers. Whereas these policies mainly aimed at facilitating reconciliation of market work and family care and promoting maternal employment, consequences for child development have received less attention in the policy debate. This DIW Roundup describes potential mechanisms how increased father (...)

Population Ageing and Its Effects on the German Economy
22 September 2015, Dirk Ulbricht
Roundup 78

The latest long-term projection of Germany’s population implies a clear trend: even though slight growth is expected over the next decade, a decline in the future is almost inevitable. Furthermore, an ageing society combined with a low fertility rate will lead to massive shrinkage of the working-age population. What are the social and economic consequences of these developments? Is a decline in economic growth unavoidable? We present the results of the long-term population projection and summarize the various effects population ageing may have on Germany.

Global Food Security
3 August 2015, Isabel Teichmann
Roundup 76

According to the current report on the Millennium Development Goals (UN 2015), the share of undernourished people living in the developing world has fallen from 23.3% in 1990-1992 to 12.9% in 2014-2016 (projection). Despite this progress towards global food security, about 795 million people worldwide (or 780 million people in developing regions) will remain undernourished in 2014-2016 (UN 2015). Put differently, more than 10% of the world population still suffers from chronic hunger (FAO et al. 2015). Moreover, globally, one in seven children under age five are projected to be underweight in (...)

Monetary Policy and the Risk-Taking Channel
28 July 2015, Michele Piffer
Roundup 75

Before the 2007 crisis, the trade-off between output and inflation played a leading role in the discussion of monetary policy. Instead, issues relating to financial stability played a less pronounced role in shaping the stance of monetary policy and were limited to asset price dynamics. This Roundup argues that the great interest that emerged after the 2007 crisis in the effects of monetary policy on financial stability reflects the shift in attention from asset price dynamics to risk-taking incentives of financial intermediaries. The Roundup reviews the economic literature that contributed to (...)

Europe’s Mechanism for Countering the Risk of Carbon Leakage
9 July 2015, Aleksandar Zaklan
Roundup 72

The EU’s Emissions Trading System (EU ETS) is a regional cap-and-trade program in a world with no binding international climate agreement. This climate regulation may induce a relocation of production away from Europe, with potentially negative consequences for the European economy. This relocation could lead to carbon leakage, i.e. a shift of greenhouse gas emissions from Europe into regions with less stringent climate policy. In response, installations in sectors deemed to be vulnerable receive compensatory free emissions allowances. The European Commission compiles a carbon leakage (...)

Foreign Direct Investment and Economic Growth
2 July 2015, Guido Baldi, Jakob Miethe
Roundup 71

Various proposals are currently being suggested to encourage higher foreign direct investment in countries within the euro area, particularly between individual member states. The intended goal is to assist in stimulating economic growth in the euro area. Against this background, this article provides an overview of the large and heterogeneous academic literature on the influence of direct investment on economic growth. The results of the existing studies indicate that direct investment often acts as a kind of catalyst and that a positive influence on economic growth becomes more probable when (...)

Peers at Work – a Brief Overview of the Literature on Peer Effects at the Workplace and the Policy Implications
4 June 2015, Clara Welteke
Roundup 68

Individuals do not exist in isolation but are embedded within networks of relationships, such as families, coworkers, neighbors, friendships or socio-economic groups. While there is a long tradition in sociology and anthropology focusing on the importance of social structure, norms and culture, economists have long ignored social influences on individual behavior. Even though social influences may play an important role in the evaluation of policies, economic evaluations are typically focused on the central question how individuals independently respond to financial incentives. However, (...)

The Debate about Financing Constraints of SMEs in Europe
21 May 2015, Franziska Bremus
Roundup 66

Small and medium-size enterprises (SMEs) are highly dependent on bank financing, which is why they have been particularly hit by tighter credit conditions in the aftermath of the global financial crisis. Given that SMEs account for about 60% of value added and 70% of employment in the euro area, they are crucial for economic recovery. Consequently, several policy initiatives have been launched to alleviate SMEs’ financing constraints. This Roundup gives an overview of the current debate about financing obstacles of SMEs in Europe and collects policy recommendations from the economic (...)

Health consequences of childhood and adolescence shocks: Is there a “critical period”?
19 May 2015, Valeria Groppo
Roundup 65

Individual health is not only determined by genetic factors, but also by negative or positive events during the life course. For example, children exposed to natural disasters or violent conflicts are more likely to have poor health as adults. Positive external factors, such as nutritional programs, will, instead, improve individual health in the long-term. In turn, health can directly affect education and income opportunities, with macroeconomic consequences for economic growth. In particular, this Roundup investigates the following question: is there an age when shocks or interventions can (...)

Large-Scale Asset Purchases by Central Banks II: Empirical Evidence
8 April 2015, Kerstin Bernoth, Philipp König
Roundup 61

Not just since the European Central Bank announced the large-scale purchase of government bonds a few weeks ago, large-scale asset purchases have always been a controversially discussed topic. This DIW Roundup summarizes the measures that have been taken by central banks in Japan, USA and UK and the empirical evidence about the impacts of these measures on financial markets and the real economy.

Central Bank Asset Purchases I: The Theory
7 April 2015, Philipp König, Kerstin Bernoth
Roundup 60

In the face of interest rates having hit their zero lower bound in major economies, large-scale asset purchases have become an important weapon of central banks in recent years. It is, however, not clear whether and under which circumstances such policy measures produce the desired effects. This DIW Roundup provides a selective overview of theoretical research that has been devoted to understand under what conditions central bank asset purchases lead to reductions in longer-term interest rates and produce stimulating effects on the overall economy.

The Market Stability Reserve: Is Europe serious about the Energy Union?
26 March 2015, , Nils May, Karsten Neuhoff
Roundup 59

The European Union Emission Trading Scheme (EU ETS) has been implemented to provide a common climate policy instrument across European Union countries, to contribute to a credible investment perspective for low-carbon investors and support further European integration of energy markets. Thus the EU ETS is a key element of the European Energy Union. However, given the accumulation of a large surplus in the EU ETS, there is now a consensus between the European Commission, the European Council and the European Union Parliament (ENVI vote) that a Market Stability Reserve (MSR) needs to be (...)

What about the OPEC cartel?
11 March 2015, Daniel Huppmann, Franziska Holz
Roundup 58

The recent decision by the Organization of the Petroleum Exporting Countries (OPEC) not to decrease their output quota in spite of a drastic decline of crude oil prices has brought renewed attention to this supplier group dominating the crude oil market. However, the empirical evidence that OPEC truly acts as a textbook cartel is rather limited. This Roundup summarizes the theories proposed over the past decades to explain the fundamental structure of the crude oil market and the role of OPEC and Saudi Arabia, the pivotal supplier. The consensus in the academic literature points towards (...)

Bubbles and Monetary Policy: To Burst or not to Burst?
10 February 2015, David Pothier, Philipp König
Roundup 55

The question of whether monetary policy should target asset prices remains a contentious issue. Prior to the 2007/08 financial crisis, central banks opted for a wait-and-see approach, remaining passive during the build-up of asset price bubbles but actively seeking to stabilize prices and output after they burst. The macroeconomic and financial turbulence that followed the subprime housing bubble has led to a renewed debate concerning monetary policy’s role in maintaining financial stability. This Round-Up provides a brief overview of this topic.

Is there a bubble in the German housing market?
19 January 2015, Konstantin A. Kholodilin, Claus Michelsen, Dirk Ulbricht
Roundup 53

After a period of stagnation that lasted for almost two decades, German house prices began to grow at an accelerated pace since late 2010. Real house prices that even had been declining in 2000-2008 started to climb up steeply from the second half of 2010, followed by a recovery of construction activities. This development raised concerns about the formation of a speculative house price bubble among German policy makers and central bankers. However, empirical evidence of a misalignment of house prices from their fundamentals is mixed.

Individual Insurance and Mutual Support Arrangements in Developing Countries
8 January 2015, Friederike Lenel
Roundup 51

Insurance coverage in the developing world is expanding rapidly. As recently as 2005, only a small number of commercial insurers offered insurance products that specifically targeted low-income people (‘microinsurance’). Seven years later, in 2012, more than half of the world’s 50 largest insurance companies were involved in microinsurance (Churchill and McCord, 2012). International donor organizations, which identified the promotion of social protection systems as a key priority, strongly encourage this development. Yet, while the positive role insurance can play for poverty (...)

The health effects of retirement
20 November 2014,
Roundup 48

Retirement leads to changes in daily life that may affect health positively or negatively. Existing empirical evidence is inconclusive: While a few studies identify negative health effects, the majority of studies find no or positive effects of retirement on health. The mechanisms behind these effects remain unclear, as is the question of which parts of the population benefit most from retirement. Recent studies indicate that retirees use their increased leisure time for healthier behavior.

Daddy leave: does it change the gender division of domestic work?
13 November 2014, Pia S. Schober
Roundup 45

How to best provide incentives for a more gender-equal division of domestic work has entered policy debates in many Western countries. Growing evidence suggests that a gender-traditional division of household labor may result in lower fertility rates and greater risk of relationship breakdown and correlates with gender employment and wage gaps. Partly in response, many European countries have implemented some individual parental leave entitlements for fathers, which are not transferable to mothers. Such non-transferable entitlements for fathers have been consistently shown to increase take-up (...)

Modelling the impact of energy and climate policies
4 November 2014, Daniel Huppmann, Franziska Holz
Roundup 44

Climate change mitigation and the transformation to a global low-carbon economy is a pressing issue in policy discussions and international negotiations. The political debate is supported by the scientific community with a large number of projections, pathway simulations and scenario analyses of the global energy system and its development over the next decades. These studies are often based on numerical economy-energy-environment-climate models. This DIW Roundup provides an overview of the model types used in the academic arena to evaluate and quantify the potential impacts of energy (...)
