Buy, Keep, or Sell: Economic Growth and the Market for Ideas

No. 3,
2016
Abstract
An endogenous growth model is developed where each period firms invest in researching and developing new ideas. An idea increases a firm's productivity. By how much depends on the technological propinquity between an idea and the firm's line of business. Ideas can be bought and sold on a market for patents. A firm can sell an idea that is not relevant to its business or buy one if it fails to innovate. The developed model is matched up with stylized facts about the market for patents in the United States. The analysis gauges how efficiency in the patent market affects growth.

Mere Criticism of the ECB is no Solution

Abstract
Criticism in Germany of the ECB is counter-productive. Monetary policy must remain expansive so that it can at least begin to fulfil the ECB mandate. The preservation of its credibility also demands that. Instead of the ECB doing less, European policymakers must do more. They need to act more decisively to set Europe back upon a growth path.
[A shorter version was published under the title “Kritik an Draghi ist noch keine Lösung“ in the Frankfurter Allgemeine Sonntagszeitung of April 10, 2016].
Policymakers, including in Germany, can no longer shirk their responsibility for the current economic situation in large parts of Europe. That calls for growth-friendly fiscal policy, structural reforms to open up new markets and consolidation and restructuring of the financial sector. We in Germany, above all, must look in the mirror, because we need the majority of these reforms just as urgently as our European neighbours do.

Joint Forecast: Migration of Refugees will Challenge Economic Policy

No. 10,
2015
Abstract
According to the Autumn 2015 Joint Forecast German GDP will grow by 1.8% in this year and in the next year also. Thus the business cycle upswing will continue to be moderate. Lower growth in the emerging markets will show a dampening effect on exports whereas private consumption will gain momentum, given a strong labor market and an increase in real wages. However, new workers are increasingly recruited from the non-active population and among immigrants, leaving unemployment more or less unchanged. In the next year, the huge current inflow of refugees will increasingly influence the number of unemployed. For economic policy the challenge is to integrate refugees into the labour market as soon as possible.

German Households Benefit from Low Interest Environment
Calculations of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association show that the average household in Germany has benefited from the low policy rate environment. The average return on their portfolio was higher than in the pre-crisis period while at the same time, they benefited from lower interest on new loans. Households in Germany had a total Euro benefit of more than 364 billion Euro over a five-year period relative to 2003 to 2007. Increases in stock prices and real estate prices over-compensate lower interest rates on savings accounts, despite their relatively low share in households’ portfolios. There are benefits across the income distribution. Households that do not own real estate lost though, but their losses are very small at on average about 100 Euro per year.

Germany Benefited Substantially from the Greek Crisis
The balanced budget in Germany is largely the result of lower interest payments due to the European debt crisis. Research from the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association shows that the debt crisis resulted in a reduction in German bund rates of about 300 basis points (BP), yielding interest savings of more than EUR 100 billion (or more than 3% of gross domestic product, GDP) during the period 2010 to 2015. A significant part of this reduction is directly attributable to the Greek crisis. When discussing the costs to the German tax payer of saving Greece, these benefits should not be overlooked, as they tend to be larger than the expenses, even in a scenario where Greece does not repay any of its debts.

Rejection of Reforms as a Chance for Reforms
The President of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association continues to see a chance for an agreement between the European Union (EU) and Greece. On the surface, Grexit looks now more likely than ever. But the resignation of Yanis Varoufakis, Minister of Finance, and the outcome of the referendum may also provide a chance for the Greek government to agree on reforms and save face. But the window of opportunity is closing very fast.

Do Manufacturing Firms Benefit from Services FDI? – Evidence from Six New EU Member States
J. Damijan, Crt Kostevc, Philipp Marek, Matija Rojec
IWH Discussion Papers,
No. 5,
2015
Abstract
This paper focuses on the effect of foreign presence in the services sector on the productivity growth of downstream customers in the manufacturing sector in six EU new member countries in the course of their accession to the European Union. For this purpose, the analysis combines firm-level information, data on economic structures and annual national input-output tables. The findings suggest that services FDI may enhance productivity of manufacturing firms in Central and Eastern European (CEE) countries through vertical forward spillovers, and thereby contribute to their competitiveness. The consideration of firm characteristics shows that the magnitude of spillover effects depends on size, ownership structure, and initial productivity level of downstream firms as well as on the diverging technological intensity across sector on the supply and demand side. The results suggest that services FDI foster productivity of domestic rather than foreign controlled firms in the host economy. For the period between 2003 and 2008, the findings suggest that the increasing share of services provided by foreign affiliates enhanced the productivity growth of domestic firms in manufacturing by 0.16%. Furthermore, the firms’ absorptive capability and the size reduce the spillover effect of services FDI on the productivity of manufacturing firms. A sectoral distinction shows that firms at the end of the value chain experience a larger productivity growth through services FDI, whereas the aggregate positive effect seems to be driven by FDI in energy supply. This does not hold for science-based industries, which are spurred by foreign presence in knowledge-intensive business services.

Understanding the Great Recession
Mathias Trabandt, Lawrence J. Christiano, Martin S. Eichenbaum
American Economic Journal: Macroeconomics,
No. 1,
2015
Abstract
We argue that the vast bulk of movements in aggregate real economic activity during the Great Recession were due to financial frictions. We reach this conclusion by looking through the lens of an estimated New Keynesian model in which firms face moderate degrees of price rigidities, no nominal rigidities in wages, and a binding zero lower bound constraint on the nominal interest rate. Our model does a good job of accounting for the joint behavior of labor and goods markets, as well as inflation, during the Great Recession. According to the model the observed fall in total factor productivity and the rise in the cost of working capital played critical roles in accounting for the small drop in inflation that occurred during the Great Recession.
