Abstract: Abstract: The balance of payments of Greenland has special features due to an important current transfer, bloktilskud, from Denmark. The trade balance does not exhibit a deficit of this order of magnitude but comparison of the bloktilskud and the deficit is difficult as official figures are available for the merchandise trade only. Figures for services are missing. However, guesses about the size of a deficit in the services’ trade do not easily discard the impression of a large surplus on the current account. Over a ten year period it is suggested that accumulated surpluses could be twice the level of Greenland’s GDP. This seems unlikely, but the available data raise a puzzle that ought to be addressed as it nourishes suspicion of unobserved accumulation of wealth.

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: Product Market Integration, Comparative Advantages and Labour Market Performance* In a two-country model with trade driven by comparative advantages, it is considered how imperfectly competitive labour markets are affected by lower frictions in international goods trade. Easier goods trading is equivalent to increased mobility of employment across countries and thus a change in the trade-off between wages and employment faced by wage setters. While the effects of product market integration on the trade-off between wages and employment in general is ambiguous, it is shown that product market integration works like a general improvement in productivity via the specialization it allows through trade. Unambiguously, real wages and employment and welfare improve upon reductions in trade frictions, and therefore workers are better off irrespective of whether the market power of unions is enhanced or muted.

Abstract: In this paper, we set up a two-country general equilibrium model where trade unions have wage bargaining power. We show that a decrease in trade distortions inducing further product market integration gives rise to specialization gains as well as a labour market reform effect. The implications of the specialization gains are similar to an increase in labour productivity, whereas the labour market reform effect is similar to an increase in the degree of competition in the labour market. Wages, employment and welfare increase as a result of further product market integration. It is interesting to note that the labour market reform effect of product market integration is achieved despite an increase in the wage level. JEL Classification: F15, J30, J50.

Abstract: We consider a model of commercial television market, where private broadcasters coexist with a public television broadcaster. Assuming that the public TV station follows a policy of Ramsey pricing whereas the private stations are profit maximizers, we consider the equilibria in this market and compare with a situation where the public station is privatized and acts as another private TV broadcaster. A closer scrutiny of the market for commercial television leads to a distinction between target rating points, which are the prime unit of account in TV advertising, and net coverage, which is the final goal of advertisers. Working with net coverage as the fundamental concept, we exploit the models of competition between public and private price and quantity in order to show that privatization of the public TV station entails a welfare loss and results in TV advertising becoming more expensive.

Abstract: This paper proposes and analyses a model of start-up investment. Innovative entrepreneurs are commercially inexperienced and can benefit from venture capital support. Only part of them succeed in matching with a venture capitalist while the rest must resort to standard bank finance. We consider a number of policies to promote entrepreneurship and venture capital backed innovation. JEL Classification: D82, G24, G28, H24.

Abstract: In recent years, venture capital has become an important source for nancing young entrepreneurial rms. Given the apparently more innovative nature and extra value added of venture capital backed rms compared to other firms, policy makers have taken an increasing interest in an active venture capital industry. We explore how selected policy instruments determine the incentives of individuals to start up new rms and of venture capitalists to nance and advise them, and how policy thereby influences the size and nature of the industry and how it aspects aggregate welfare. We examine the impact of wage and corporate income taxes as well as capital gains taxes and start-up capital subsidies on the volume and quality of venture capital backed entrepreneurship.

An explorative study of the contracts of the Tender Electronic Daily (TED)la Cour, Lisbeth; Milhøj, Anders (Frederiksberg, 2013)[More information][Less information]
Abstract: Public procurement is estimated to constitute more than 16% of GDP in the EU, see e.g. Ramsey (2006). This is one of the reasons why a lot of interest has been attached to this topic. Most of the papers in this field have been of a theoretical nature but during the last ten years also a few empirical studies have become available, see e.g. Marion, J. (2007) and Bajari et al (2008). At the EU level liberalizations have been going on since the late 80’ies (see e.g. the EU commission (1985). Here certain regulations imply that public projects of a certain size need to be subject to a public tender. Again according to Ramsey (2006) around 16% of all public procurement in the EU is subject to these rules and regulations and information on the contracts corresponding to these 16% can be found in Tenders Electronic Daily (TED) database. In general, the hypothesis is that public procurement will increase competition and ultimately lead to cheaper contracts for the authorities, see e.g. Cecchini (1988) for the economic arguments. But in practice: do the rules and regulations ensure more competition? Do they lead to more internationalization in the sense that more foreign firms become contract winners? Do the government and municipalities in the EU countries actually gain economically from the procurement? Does the choice of type of procedure matter? A lot of interesting questions immediately pops up and some of them – but only some of them - may be analyzed based on the content of this data base. Still, due to the large coverage and the international nature of the data base we believe that a thoroughly study of the possibilities of TED is of major interest and the present study is just a first step in this direction. One of the students who extracted the TED data has also used them for analysis in his master thesis, see Bundsgaard (2010). He has, however, limited his interest to analyze the choice of procedure: auction vs. negotiation and therefore our study has a broader scope when it comes to available variables. To our knowledge we are the first group of researchers who begins to analyze the content of this database using explorative statistical techniques based on a broad range of variables.

the Danish stock market since World War 1Risager, Ole (København, 1998)[More information][Less information]
Abstract: Abstract: This paper contributes to the growing literature on mean reversion in stock markets by examining a newly constructed Danish data set for the period 1922-95. Variance ratio tests clearly reject the random walk hypothesis at the 2-year horizon, that is, the riskiness of a 2- year investment is significantly less than twice the risk of a 1-year investment. Variance ratio tests for 3- and 4-year horizons are not significant under conventional significance levels, whereas autocorrelation tests of the joint hypothesis that there is departure from random walk at all horizons tend to reject the random walk hypothesis and support the mean reversion hypothesis.

Staff utilisation in branches of a large Canadian bankAsmild, Mette; Bogetoft, Peter; Hougaard, Jens Leth (, 2011)[More information][Less information]
Abstract: In this paper we consider staffing decisions in branches of a large Canadian bank. The bank has well-developed staffing models and the branches work in a highly competitive environment. One would therefore expect limited ’inefficiency’ in the sense of wasted resources and over-staffing. Using Data Envelopment Analysis (DEA) we nevertheless find considerable ’inefficiency’ which raises the question whether this is best interpreted as waste or if the apparent inefficiency may serve other purposes. To investigate this, we invoke the theoretical framework of Rational Inefficiency (Bogetoft and Hougaard 2003). A systematic pattern of slack consumption emerges, which suggests that the allocation of slack between sta↵ groups is far from random. The slack pattern seems natural from the point of view of employee value and hierarchy and also considering employee flexibility and substitutability. For example we find relatively large over-staffing at the supervisor level which is natural given both their strong bargaining position derived from their role in the branch hierarchy and given the relative flexibility of supervisor resources.

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.

Three papers laying the foundation for regional CGE models with agglomeration characteristicsTermansen, Lars Brømsøe (Frederiksberg, 2008)[More information][Less information]
Abstract: The paper analyses the effects of introducing taxes and regional transfers on the equilibrium properties in a standard Core-Periphery model. A central government levies taxes on production factors and redistributes the revenue to all agents regardless of their location. In the case of Core-Periphery economy this is in effect a re-allocation of agglomeration rents. Simulations show that taxes and transfers alter the Core-Periphery model’s properties by moving the Break and Sustain points. The range of freeness of trade with Core-Periphery outcomes is reduced for transfers to the periphery, and increased for transfers to the core. The width of the overlap where the models exhibit hysteresis effects remains the same regardless of the transfers. The analysis reveals that in the Core-Periphery outcome the agglomeration rents can be taxed without exhausting the core’s scale effects. The tax revenues can then be redistributed such that periphery regions and the central government have incentives in promoting core regions, which function as industrial locomotives for the whole economy.

Abstract: Resource rents and models for taxation of these rents. Some references to the situation for Greenland. After a general introduction to the concept of rents the risk of distortion by double taxation of the normal capital income to investment is explained. Cash flow taxation or deduction in the tax base of investment times the risk free interest rate can be used to avoid this double taxation. Among other instruments to secure a part of rents for the public sector are direct participation and selling rights to exploit the resources by auction. The greater part of the paper is about taxation of rents in fisheries. The regulation is assumed to be based on professional advising and individual transferable quotas. Duties on the quota or a general cost increasing tariff, e. g. on fuel, are administratively simple models for taxation. Cost increasing indirect taxation has the good quality of incentive compatibility, as it supports the effort reducing aim of regulation. A concrete example illustrates a possible taxation of the prawn/shrimp fishery combining a duty on the quota with a tariff levied on the catch. Some comment are given on a recent report on the shrimp fishery (2005), and it is criticised for highlighting the theoretical qualities of Greenland’s fisheries policy, but neglecting the regulation and also to which extent incomes derived from quotas end up as income for Greenlandic households.
