Abstract
To what extent and in what form should the intellectual property rights (IPR) of innovators be protected? Should a company with a large technology lead over its rivals receive the same IPR protection as a company with a more limited advantage? In this paper, we develop a dynamic framework for the study of the interactions between IPR and competition, in particular to understand the impact of such policies on future incentives. The economy consists of many industries and firms engaged in cumulative (step-by-step) innovation. IPR policy regulates whether followers in an industry can copy the technology of the leader. We prove the existence of a steady-state equilibrium and characterize some of its properties. We then quantitatively investigate the implications of different types of IPR policy on the equilibrium growth rate and welfare. The most important result from this exercise is that full patent protection is not optimal; instead, optimal policy involves state-dependent IPR protection, providing greater protection to technology leaders that are further ahead than those that are close to their followers. This is because of a trickle-down effect: providing greater protection to firms that are further ahead of their followers than a certain threshold increases the R&D incentives also for all technology leaders that are less advanced than this threshold.

Protect and Survive? Did Capital Controls Help Shield Emerging Markets from the Crisis?
Makram El-Shagi
Economics Bulletin,
No. 1,
2012
Abstract
Using a new dataset on capital market regulation, we analyze whether capital controls helped protect emerging markets from the real economic consequences of the 2009 financial and economic crisis. The impact of the crisis is measured by the 2009 forecast error of a panel state space model, which analyzes the business cycle dynamics of 63 middle-income countries. We find that neither capital controls in general nor controls that were specifically targeted to derivatives (that played a crucial role during the crisis) helped shield economies. However, banking regulation that limits the exposure of banks to global risks has been highly successful.

Abstract
The aim of this study is to assess the contributions of investment banking to the economy with a particular focus on the German economy. To this end we analyse both the economic benefits and the costs stemming from investment banking.
The study focuses on investment banks as this part of banking is particularly relevant for financing companies as well as the development and use of specific products to support the needs of private and professional clients. The assessment of benefits and costs of investment banking has been conducted from a European perspective. Nevertheless there is a focus on the German economy to allow a more detailed analysis of certain aspects as for example the use of derivatives by German companies, the success of M&As in Germany or the effect of securitization on loan supply and GDP in Germany. For comparison purposes other European countries and also the U.S. have been taken into account.
The last financial crisis has shown the negative impacts of banks on the financial system and the whole economy. In a study on the contribution of investment banks to systemic risk we quantify the negative side of the investment banking business.
In the last part of the study we assess how the effects of regulatory changes on investment banking. All important changes in banking and capital market regulation are taken into account such as Basel III, additional capital requirements for systemically important financial institutions, regulation of OTC derivatives and specific taxes.

Firm level determinants of innovation: small firms with high potential in East Germany
Jutta Günther, Philipp Marek
Wirtschaft im Wandel,
No. 7,
2011
Abstract
Innovations in the sense of new products and production processes are crucial drivers of the economic development in advanced economies. After a phase of massive technological renewal in East Germany, characterized by much a higher rate of innovators in East than in West Germany, firms in East Germany have to compete with original innovation activities. The paper outlines the innovation activity in East and West Germany and investigates the determinants of product and process innovation within a multivariate analysis using the IAB establishment panel.
The empirical study shows that firms in manufacturing industry in East Germany are quite active in innovation activities in the year 2008. As regards the share of innovative firms there are no substantial differences between East and West Germany. The regression analysis shows that R&D is a significant determinant of innovation in East and West for all types of innovation. In East Germany, further education activities for employees also show a statistically significant impact on innovation. A major difference between East and West could be found for the firm size. In East Germany size has no significant impact on innovation while in West Germany size clearly matters. Different from West Germany, small firms (10 up to 49 employees) in the East have a significantly positive impact on product innovations in the sense of market novelties.

The Revealed Competitiveness of U.S. Exports

Federal Reserve Discussion Paper,
No. 1026,
2011
Abstract
The U.S. share of world merchandise exports has declined sharply over the last decade. Using data at the level of detailed industries, this paper analyzes the decline in U.S. share against the backdrop of alternative measures of the competitiveness of the U.S. economy. We document the following facts: (i) only a few industries contributed to the decline in any meaningful way, (ii) a large part of the drop was driven by the changing size of U.S. export industries and not the size of U.S. sales within those industries, (iii) in a gravity framework, the majority of the decline in the U.S. export share within industries was due to the declining U.S. share of world income, and (iv) in a computed structural measure of firm productivity, average U.S. export productivity has generally maintained its high level versus other countries over time. Overall, our analysis suggests that the dismal performance of the U.S. market share is not a sufficient statistic for competitiveness.

Ageing and Labour Markets: An Analysis on the effect of worker’s age on productivity, innovation and mobility
Lutz Schneider
Technische Universität Dresden. Dissertation,
2011
Abstract
The present study analyses the labour market effect of workers’ ageing. Explicitly, the impact of age on productivity and wages, on innovation as well as on mobility is explored empirically. The econometric analyses are based on firm and employment data from the Institute for Employment Research (IAB) and, thus, refer to the labour market of Germany. Regarding the productivity and wage effects of age the econometric results confirm a positive correlation between firm productivity and the share of middle-aged employees (41-50 years old) within the manufacturing sector. Hence, the results provide evidence of an inverted u-shaped age-productivity profile in this sector also found for other countries. Furthermore, age-wage and age-productivity profiles seem to follow unequal patterns. Compared to the group of the 15-30 and the 51 and above years old workers the group of middle-aged employees earn less than a productivity based wage scheme would require. In terms of age effects on innovativeness the micro-econometric analysis again reveals an inverted u-shaped profile. Workers aged around 40 years seem to act as key driver for innovation activities within firms. An additional finding concerns the impact of age diversity on innovation. The expected positive effect of a heterogeneous age structure is not confirmed by the data. With respect to labour market mobility results are in favour of a negative correlation between age and job mobility either in terms of changing professions or firms. The estimation of a multi equation model verifies that expected wages of older workers do not or only marginally increase due to job mobility, so, financial incentives to change jobs are very low. Yet, even after controlling the absent wage incentive older employees still remain more immobile than younger workers. Altogether, these results should not only be of academic interest but also informative for actors on the firm and the governmental level. Both sides are asked to cope with the challenges of demographic change. Only by maintaining productivity and innovativeness until old ages the necessary resources can be generated to preserve an economy’s prosperity even if the share of non-active population is increasing by demographic developments. Secondly, enhancing productivity is essential to ensure employability of older persons and to sustain the size of workforce even in the circumstances of an ageing economy.

Regulation and Taxation: A Complementarity
Benjamin Schoefer
Journal of Comparative Economics,
No. 4,
2010
Abstract
I show how quantity regulation can lower elasticities and thereby increase optimal tax rates. Such regulation imposes regulatory incentives for particular choice quantities. Their strength varies between zero (laissez faire) and infinite (command economy). In the latter case, regulation effectively eliminates any intensive behavioral responses to taxes; a previously distortionary tax becomes a lump sum. For intermediate regulation (where some deviation is feasible), intensive behavioral responses are still weaker than under zero regulation, and so quantity regulation reduces elasticities, thereby facilitating subsequent taxation. I apply this mechanism to labor supply and present correlational evidence for this complementarity: hours worked in high-regulation countries are compressed, and these countries tax labor at higher rates.

Immigration to East Germany: Last chance 2011
Alexander Kubis, Lutz Schneider
Wirtschaft im Wandel,
No. 4,
2010
Abstract
Due to population ageing and shrinking Germany – particularly East Germany – experiences a demographic constellation causing remarkable economic and social problems. One option to cope with the demography based challenges is immigration. In a historical part the article firstly illustrates the history of immigration in Germany during the 20th century and concludes that substantial immigration initially occurred in the 1950th in the Western part of Germany when the so called “Gastarbeiter” were attracted to the West German labour market. Regions in East Germany, instead, show a rather low share of immigrants – a result of the GDR immigration policy that permitted only a low level of temporary migration.
However, prospects of success to stimulate immigration to East Germany seem to be rather limited. Firstly, since 2000 Germany as a whole faces reducing immigration numbers. Secondly, the low immigration experience and density of foreigners’ networks could torpedo existing immigration potentials. The sole opportunity for improving the migration balance seems to be the immigration from Central Eastern European regions. Spatial proximity might compensate for lacking migration incentives and initiate substantial migration flows towards East Germany. Yet, one should not have to high expectation regarding the dimension of immi-gration from Central Eastern Europe. Large parts of the migratory population already moved to other EU member states that implemented the Freedom of Movement for Workers immediately after 2004. Therefore, it seems to be crucial to stay away from every supplementary regulation that might discourage potential labour market migrants from Central East Europe after May 2011.

Change in East German Firm Level Export Determinants
Birgit Schultz
Wirtschaft im Wandel,
No. 3,
2010
Abstract
Exports have a ‘motor of growth’ status for the German economy. They both save and increase employment and provide wealth. However, only a minority of East German manufacturing and construction firms realize sales in foreign countries. The paper analyses for two points in time the influences of firm level export factors on the level of export activities of East German firms, and how the strength of the influence has changed over time. We found export sales especially in firms who are integrated in international corporate groups and are highly specialized. Economies of scale (firm size) increase the export share. Additionally, export sales also depend on wages. These findings are in line with current analysis in the field of international trade. While the above factors are found to be stable over time some others have changed in importance. In 2000 the industrial sector and the unit labor costs were important factors in determining export activities. In 2008 these factors have lost importance. Instead, human capital and investments have achieved significance.

Foreign Investors and Domestic Suppliers: What Feeds Positive External Effects?
Jutta Günther, Björn Jindra, Daniel Sischka
Wirtschaft im Wandel,
No. 9,
2009
Abstract
The empirical study analyses the potential for positive external effects from foreign investors in favor of domestic firms using the IWH-FDI micro database and taking into account firm-specific characteristics of foreign investors in selected Central and East European countries as well as in Eastern Germany. The analysis shows that only half of the foreign investors believe that they are important for technological activities in domestic supplier firms. Thereby, the potential for external positive effects is higher in Central and Eastern Europe than in Eastern Germany. A reason for this might be that supplier firms in Eastern Germany already operate on a clearly higher technological level than their counterparts in Central and Eastern Europe. Taking into account the share of domestic supplies of foreign investors, it shows that the potential for positive external effects increases only to a certain point from which on the spillover potential stagnates or even declines. Furthermore, there is clear evidence for the following characteristics of foreign investors to increase the potential for positive external effects: innovativeness of the foreign investor, internal and external technological cooperation of foreign investors, independence from the headquarters in research and development issues and market entry through acquisition (instead of greenfield investment). The share of foreign participation as well as the duration of presence in the host economy does not show any statistically significant effect on the potential for external effects. Policy makers should therefore not only aim at the settlement of employment intensive foreign investors, but also and particularly support investors that are characterized by technological activity and regional integration.
