En analyse baseret på branche- og landeforskelleKromann, Lene; Rose Skaksen, Jan; Sørensen, Anders (, 2012)[More information][Less information]
Abstract: Formålet med analysen er at udnytte lande- og brancheforskelle i automation, produktivitet og beskæftigelse til at afklare i hvilken udstrækning automation påvirker produktivitet og beskæftigelse. Detaljer omkring analysen findes i: ”Automation, labor productivity and employment – a cross country comparison”. Et hovedresultat er, at arbejdsproduktiviteten i fremstillingssektoren i Danmark kan forøges med ca. 15%, hvis de enkelte brancher indenfor fremstillingssektoren udnytter automation i samme udstrækning, som i de lande, der er mest automatiserede. Det vil på kort sigt også betyde, at beskæftigelsen tendere mod at falde med 7%, men til gengæld vil den vokse med 5% på længere sigt. URI: http://hdl.handle.net/10398/8649 Files in this item: 1

Inference from the Business CycleRose Skaksen, Jan; Sørensen, Anders (København, 2004)[More information][Less information]
Abstract: The relative demand for skills has increased considerably in many OECD countries during recent decades. This development is potentially explained by capital-skill complementarity and high growth rates of capital equipment. When production functions are characterized by capital-skill complementarity, relative wages and employment of skilled labor are countercyclical because capital equipment is a quasi- fixed factor in the short run. The exact behavior of the two variables depends on relative wage flexibility. Relative wages are rigid in Denmark, implying that the employment share of skills should be countercyclical. The labor market is competitive in the United States and therefore relative wages of skilled labor are expected to be countercyclical. We find that the business cycle development of the two economies is consistent with capital-skill complementarity.

Abstract: Der er klar sammenhæng mellem danske virksomheders digitaliseringsstrategi og produktivitet. Det viser denne rapport, som CEBR har udarbejdet for IT- og Telestyrelsen på grundlag af en pålidelig stikprøve på omkring 8.500 danske virksomheder. Et af rapportens nøgleresultater er, at en 1 procent-point større andel af virksomheder, som har digitaliseret visse forretningsprocesser, er knyttet til 0,72 procent højere værditilvækst pr. medarbejder. Det svarer i et makroøkonomisk perspektiv til mellem 2,6 og 6,5 milliarder kroner i årlig bruttoværditilvækst. URI: http://hdl.handle.net/10398/8481 Files in this item: 1

Dalgaard, Carl-Johan; Schultz, Esben Anton; Sørensen, Anders (Frederiksberg, 2009)[More information][Less information]
Abstract: Is the wage gap between majors in human arts and other fields caused by the education? If the educational choice is endogenous, the wage gap may instead be caused by selection. We document that individuals’ educational choice is correlated with that of older students and by the concentration of women in their high school. Conditional on high school fixed effects, these characteristics are unlikely to affect post-university wages and are plausible instruments for the educational choice. Our 2SLS estimates reveal that the gap in returns to education is negligible, implying that the wage gap is attributable to selection. URI: http://hdl.handle.net/10398/7989 Files in this item: 1

Abstract: Is the wage gap between majors in human arts and other fields caused by their education per se? If the educational choice is endogenous, the gap may instead be caused by selection. We document that individuals’ educational choice is correlated with that of older students, and argue that it should not influence wages directly. Exploiting this "cohort dependence" as an instrument for educational choice, our 2SLS estimates show that the hourly wage gap is attributable to selection. However, only half of the gap in annual earnings is explained by selection, whereas the other half is due to lower work hours. URI: http://hdl.handle.net/10398/8521 Files in this item: 1

Iversen, Jens; Malchow-Møller, Nikolaj; Sørensen, Anders (Frederiksberg, 2009)[More information][Less information]
Abstract: We argue that formal schooling and wage-work experience are complementary types of human capital for entrepreneurs. Strong empirical support is found for this hypothesis as the interaction term between schooling and actual wage-work experience enters positively and significantly in a Mincer equation, whereas the effect of schooling in the absence of wage-work experience is insignificant. These results are extremely robust towards more flexible specifications, including fixed-effects estimations dealing with unobserved heterogeneity. For wage workers, the interaction term is negligible, confirming that the complementarity is a distinct characteristic of entrepreneurial human capital.

Abstract: This paper analyses the importance of entrepreneurs for job creation and wage growth. Relying on unique data that covers all plants, firms and individuals in the Danish private sector, we are able to distil a number of different measures of entrepreneurial plants from the set of new plants, including measures that much more precisely capture the "truly new” or "entrepreneurial” plants than in previous studies. Using these data, we find that while new plants in general account for one third of the gross job creation in the economy, entrepreneurial plants are responsible for between 15% and 25% of this, and thus only account for up to 8% of total gross job creation in the economy. However, entrepreneurial plants seem to generate more additional jobs than other new plants in the years following entry. Finally, the jobs generated by entrepreneurial plants are to a large extent low-wage jobs, as they are not found to contribute to the growth in average wages. However, this insight varies across the different types of entrepreneurial plants. URI: http://hdl.handle.net/10398/7713 Files in this item: 1

Abstract: This paper investigates the importance of the educational mix of employees at the firm level for the probability of firms being involved in innovation activities. We distinguish between four types of innovation: product, process, organisational, and marketing innovation. Moreover, we consider three different types of education for employees with at least 16 years of schooling: technical sciences, social sciences, and humanities. Furthermore, we examine the influence of these different innovation activities on firm productivity. Using a rotating panel data sample of Danish firms, we find that different types of innovations are related to distinct educational types. Moreover, we find that firms that adopt product and marketing innovation are more productive than firms that adopt product innovation but not marketing innovation and firms that adopt marketing innovation but not product innovation. In addition, firms that adopt organisational and process innovation demonstrate greated productivity levels than forms that adopt organisational innovation but not process innovation that again demonstrate greater productivity than firms that do not adopt process innovation but not organisational innovation. Finally, we establish that product and marketing innovation as well as organisational and process innovation are complementary inputs using formal tests for supermodularity. Complementarity can be rejected for all other pairs of innovation types. URI: http://hdl.handle.net/10398/8498 Files in this item: 1

Panel Data Evidence on EuropeDahl, Christian M.; Kongsted, Hans Christian; Sørensen, Anders (Frederiksberg, 2009)[More information][Less information]
Abstract: What has been the quantitative effect on productivity growth of information and communication technology (ICT) in Europe after 1995? Based on a multi-country sectoral panel data set, we provide econometric evidence of positive and significant productivity effects of ICT in Europe, mainly due to advances in total factor productivity. In contrast to the US, this impact of ICT has happened against a negative macro economic shock not related to ICT. Our main result is in contrast to the established consensus in the growth accounting literature that there has been no acceleration of productivity growth in Europe, mainly due to the performance of ICT-using sectors. One important advantage of using econometric methods is that we can distinguish between growth effects from ICT and macro economic shocks; a feature that growth accounting methods cannot handle.

Abstract: This paper investigates the impact of globalization, in the sense of increasing international trade, on the demand for skills in Danish manufacturing companies. The study is based on a unique data set that enables us to develop rich measures of international outsourcing and import penetration. Moreover, the data also allows several strategies to strengthen the causal interpretation of our results. The main finding of the analysis is that it is of crucial importance to distinguish imports - both in the form of outsourcing and overall imports - by country-of-origin. We find that international trade with low-wage countries leads to skill-upgrading. This is especially pronounced for import penetration with a ceteris paribus contribution of around fifty percent to skill-upgrading. Moreover, we find that import penetration in goods originating from high-wage countries lead to skill-downgrading. This latter result suggests that Danish manufacturing has comparative advantage in skill intensive production when compared to low-wage countries, but in unskill-intensive production when compared to high-wage countries.

Abstract: Welfare ranking of policy instruments is addressed in a two-sector Ramsey model with monopoly pricing in one sector as the only distortion. When government spending is restricted, i.e. when a government is unable or unwilling to finance the required costs for implementing the optimum policy, subsidies that directly affect investment incentives may generate higher welfare effects than the direct instrument, which is a production subsidy. The driving mechanism is that an investment subsidy may be more cost effective than the direct instrument; and that the relative welfare gain from cost effectiveness can exceed the welfare loss from introducing new distortions. Moreover, it is found that the investment subsidy is gradually phased out of the welfare maximizing policy, which may be a policy combining the two subsidies, when the level of government spending is increased.

Abstract: The role of product and marketing innovation for productivity growth is addressed using survey and register data for the Danish economy. It is argued that marketing and product innovation are complementary inputs and that innovation activities are skill-intensive. It is found that product and marketing innovation in skill-intensive firms results in significantly faster productivity growth than in unskilled-intensive firms that introduce this combination of innovation activities. More precisely, an increase in the share of educated workers of one percentage point, increases productivity growth by around 0.1 percentage point in firms with product and marketing innovation. In addition, it is found that firms that engage in product innovation but not in marketing innovation or the other way around do not demonstrate a growth effect from their innovation activities. It is also found that product and marketing innovation has an independent role in productivity growth that cannot be attributed to organisational changes, even though the majority of innovative firms engage in this latter innovation type.

Abstract: It may be optimal from a welfare perspective to use R&D subsidies when the source of R&D distortions originates from the surplus appropriability problem and technological spillovers in the form of knowledge spillovers, creative destruction, and duplication externalities are absent. Hence, R&D subsidies may constitute the optimal policy even when subsidies directly targeted on monopoly pricing could be applied. The result holds when dynamic effects are important relative to static effects and when governments spending is restricted. The latter characteristic arises when a government is unable or unwilling to use the level of spending required to implement the optimum policy. The argument is developed in a semi-endogenous growth model where the only distortion is monopoly pricing of intermediate goods.

Heterogeneity and Non-LinearitiesIversen, Jens; Malchow-Møller, Nikolaj; Sørensen, Anders (Frederiksberg, 2010)[More information][Less information]
Abstract: The returns to education in self-employment are addressed in four different specifications of the relationship between log income and years of schooling. The specifications range from a standard Mincer equation with a constant percentage increase in income to an additional year of schooling to the most flexible specification with dummy variables for the different number of years of schooling split into different types of education. Based on the more flexible specifications, important non-linearities and heterogeneity in the returns to education in self-employment are found. These results are robust across different estimation methods: OLS; Heckit correction models to handle sample selection; and IV to deal with the potential endogeneity of years of schooling. Moreover, the results are insensitive to the use of different sample years, different definitions of self-employment, and different income measures for the self-employed.

Country-of-Origin or End-Use of Products.Sørensen, Anders (København, 2007)[More information][Less information]
Abstract: This paper investigates the empirical consequences for the relationship between skill upgrading and internationalization by decomposing import after country-of-origin and after the end-use of products. I find that the break-down after country-of-origin is of crucial importance, implying that international trade with low-wage countries leads to comprehensive skill upgrading, whereas international trade with high-wage countries leads to skill downgrading in Danish Manufacturing. The empirical literature on skill-upgrading and internationalization has mainly focused on international outsourcing and has to a large extent disregarded import penetration. By splitting import after country-of-origin, this reintroduces import penetration as an important explanation for skill upgrading. skill upgrading, import, country-of-origin, end-use of products URI: http://hdl.handle.net/10398/7686 Files in this item: 1
