Recent developments and dependencies on prices/taxesla Cour, Lisbeth; Milhøj, Anders (København, 2005)[More information][Less information]
Abstract: In the following we will analyse the sale of alcohol in Denmark. Various figures related to this question are published by Statistics Denmark at different frequencies. Our main concern will be with quarterly data for the sale of beer, wine and spirits from the period 1990 – 2004. Our two hypotheses are: First we want to convince the reader that the total sale of alcohol in Denmark since 1980 has been fairly stable. By total sale we mean the total sale of 100% alcohol so the three categories – beer, wine and spirits are measured in litres of 100% alcohol equivalents. In order to convince the reader that the total sale of alcohol has been fairly constant we will present graphs and various indicators and tests of the degree of temporal dependence in this series. The overall impression from this analysis is that our first hypothesis seems to be supported – at least not contradicted – by the data. Next, we want to model the sale of beer and wine as shares of the total sale of alcohol. Even though the total sale can be considered fairly stable there have been divergent paths of evolvement for the sub-groups: the sale of beer has decreased over the period and the sale of wine has increased. The sale of spirits has been fairly stable. Modelling the system of the beer-share and the wine-share we want to split the total development into a part that can be ascribed to changes in the relative prices and a part that can be explained by changes in taste and drinking habits specified as a trend. By specifying a system conditionally on the prices of beer, wine and spirits and a trend we manage to estimate price sensitivity and taste sensitivity. A small forecasting exercise shows that the final model is fairly good at predicting changes in the shares due to price changes. Finally, the effects on the market shares of hypothetical changes in the taxation of alcohol are discussed. URI: http://hdl.handle.net/10398/7532 Files in this item: 1

Abstract: The focus is effects of investments in airports and runways on the market for air travel and more in general for the production possibilities of the economy. In the case of Greenland two types of impacts can be sorted out. One is more efficient production of air transport due to increased density in the utilization of the net because of no use or less use of the airport in Kangerlussuaq. The other effect, connected to the first, is that resources are set free by avoidance of double work receiving the same passengers (and goods) in Kangerlussuaq and especially in Nuuk. Transformation curves are used to illustrate both effects and the first is dealt with also in an ordinary price quantity diagram. Using previous calculations and estimates done by the author two specific scenarios are treated in the theoretical framework presented: one is a lengthening of the runway in Nuuk to 1799 m and less intensive use of Kangerlussuaq, the other is the building of an airport south of Nuuk with a 3000 m runway in combination with abandoning Kangerlussuaq. Profitability and amortisation of the investments are reviewed in transformation curve diagrams. On the assumptions of the calculations both scenarios are profitable, but by far the most profitable is the big investment south of Nuuk. Concluding remarks stress the preliminary character of my calculations, but they also point out that decision makers’ choice of scenarios to be discussed and compared is unstable.

The relevant antitrust market for salmonHaldrup, Niels; Møllgaard, Peter; Kastberg Nielsen, Claus (København, 2005)[More information][Less information]
Abstract: Delineation of the relevant market forms a pivotal part of most antitrust cases. The standard approach is sequential. First the product market is delineated, then the geographical market is defined. Demand and supply substitution in both the product dimension and the geographical dimension will normally be stronger than substitution in either dimension. By ignoring this one might decide first to define products narrowly and then to define the geographical extent narrowly ignoring the possibility of a diagonal substitution. These reflections are important in the empirical delineation of product and geographical markets. Using a unique data set for prices of Norwegian and Scottish salmon, we propose a methodology for simultaneous market delineation and we demonstrate that compared to a sequential approach conclusions will be reversed.

Abstract: Processing ashore of raw materials from the fisheries tend intuitively to recommend itself because more creation of value added in this manner should take place in Greenland. However, we observe the opposite tendency: production is shifted aboard on factory trawlers and catches are shipped directly to export markets or may be so after transshipping in e.g. Nuuk. It is shown that this actual development indeed is the prediction of location economics. In the case of unemployment it may be optimal to secure raw materials for processing on plants ashore, an aim that may be achieved via subsidies. The optimality of such policy is discussed using concepts from cost benefit analysis, and it is demonstrated how the shadow price of labor has a crucial role. Shifting to the macro level capacity restrictions on plants and on the labor market are pointed out. The effect of taking raw material ashore is illustrated with a macro production function, which is assumed to have a positive marginal product until the capacity limit is hit. This, however, may take place after the noninflationary augmenting level of employment has been reached. Finally the possibility of alternative and better policies than the one relying on subsidies is touched upon. URI: http://hdl.handle.net/10398/7570 Files in this item: 1

A Disaggregate PerspectiveMalchow-Møller, Nikolaj; Skaksen, Jan Rose (København, 2003)[More information][Less information]
Abstract: Skill-Biased Technological Change in Denmark: A Disaggregate Perspective* In this paper, we provide an industry-level analysis of skill-biased technological change (SBTC) in Denmark over the last two decades. The analysis shows that SBTC has varied considerably across industries, and traditionally large Danish industries have experienced relatively less SBTC. This may partly explain why wage inequality between skilled and less skilled has risen less in Denmark than in other countries. We also find that SBTC has been concentrated in already skill-intensive industries. This contains important information about future labour requirements, as the relative importance of these industries must be expected to grow, thereby reinforcing the shift in demand for skilled labour.

Larsen, Birthe (København, 2004)[More information][Less information]
Abstract: This paper examines the implications of that workers may not be able to estimate their true costs of acquiring skills. Consequently, too few workers may acquire skills. This allows for the possibility that subsidizing education is welfare improving. Furthermore, if the presence of skill-biased technological shocks increase unemployment, this may explain why the market it-self cannot respond to this by making it sufficiently attractive to acquire skills. Consequently, the trade-off in-between subsidizing education and thereby reducing unemployment and optimizing welfare may be eliminated. We analyse this issue in a simple educational model and next in a search equilibrium model including a skill choice decision. Keywords: Education, subsidies, efficiency, unemployment.

Abstract: We find that the main featues of labor policy across OECD countries can be explained by a simple general equilibrium search model with risk neutral agents and a government that chooses policy to maximize a social welfare function. In equilibrum, policies are chosen to optimal redistribute income from advantaged to disadvantaged workers. A worker can be disadvantaged in the sense that they may have less ability to aquire and utilize skills in the workplace. The model explains why passive benefits tend to fall and active benefits tend to increase during the course of unemployment spell. The model also explains why countries that appear to pursue equity spend more on both active and passive labor market programs. URI: http://hdl.handle.net/10398/7648 Files in this item: 1

Abstract: This paper studies the impact of outsourcing on individual wages. In contrast to the standard approach in the literature, we focus on domestic outsourcing as well as foreign outsourcing. By using a simple theoretical model, we argue that, if outsourcing is associated with specialization gains arising from an increase in the extent of the market for intermediate goods, domestic outsourcing tends to increase wages for both unskilled and skilled labor. We use a panel data set of workers in Danish manufacturing industries to show that domestic and foreign outsurcing affect wages as predicted by the theory.

Abstract: This paper introduces the concept of a steepest ascent tariff reform for a small open economy. By construction, it is locally optimal in that it yields the highest gain in utility of any feasible tariff reform vector of the same length. Accordingly, it provides a convenient benchmark for the evaluation of the welfare effectiveness of other well known tariff reform rules, as e.g. the proportional and the concertina rules. We develop the properties of this tariff reform, characterize the sources of the potential welfare gains from tariff reform, use it to establish conditions under which some existing reforms are locally optimal, provide geometric illustrations and compare welfare effectiveness of reforms using numerical examples. Moreover, being a general concept, we apply it to the issue of market access and examine its implications. Overall, the paper’s contribution lies in presenting a theoretical concept where the focus is upon the size of welfare gains accruing from tariff reforms rather than simply with the direction of welfare effects that has been the concern of the literature.

Abstract: This paper examines the macroeconomic effects of youth unemployment programmes in the form of vocational training (YUPs), developing a two sector general equilibrium model featuring matching frictions and worker-fi rm wage bargaining for skilled workers. Unskilled sector wages are indexed to skilled sector wages. Workers differ with respect to ability, having importance for the young worker s skill decision. Furthermore, a young worker may be offered vocational training through YUPs. The total number of skilled workers is therefore determined by these two channels and the interaction between them. We focus on the impact of of YUPs on skill division, unemployment distribution workers and aggregate unemployment.
