De-industrialization and comparative advantage in the global value chain

We investigate the causes of de-industrialization and potential for re-industrialization using trade-linked input–output data from WIOD. By introducing a new global value chain measure of comparative advantage, we relate a sector's share in domestic final demand to that in production and separate the direct effect of trade on its income share. This method identifies the declining share of manufacturing value added in domestic final expenditures to be the main cause of de-industrialization. Differences in comparative advantage between countries do matter, especially in the case of employment shares, but have a limited impact via the direct trade effect on value added. The findings point to a peculiar paradox of industrial policy: precisely when it is successful in raising competitiveness and hence productivity growth of manufacturing, it also furthers the global decline of relative prices in manufacturing. In contrast to the national objectives of re-industrialization, effective industrial policies accelerate de-industrialization in the global economy.     

A dynamic common property resource problem with amenity value and extraction costs

An analytically tractable differential game is presented that describes the exploitation of a common-property resource by finitely many competing players. The resource stock has an amenity value and there are positive extraction costs. We derive both the cooperative solution and Markov-perfect Nash equilibria of the non-cooperative game. After a comparative analysis of the equilibrium strategies and payoffs with respect to all model parameters, we study the effect of a unilateral extraction restriction and discuss the design of a revenue-neutral tax/transfer scheme that supports the cooperative solution.     

Imperfect competition and capital accumulation: the role of price normalization

We consider a capital-accumulation model with infinitely lived households and two production sectors. The intermediate-good sector is characterized by perfect competition, a constant-returns-to-scale technology, and production externalities. The final-good sector is a monopoly operating under constant returns to scale. We analyze the general equilibrium in the sense of Gabszewicz and Vial [Journal of Economic Theory (1972) 4: 381–400] for this economy and different price-normalization rules. It is shown that the qualitative behavior of the equilibrium paths depends crucially on the chosen normalization rule. In particular, whether equilibria are monotonic or oscillating and whether indeterminacy occurs or not may depend on the choice of the numeraire.     

Customer segmentation in retailing based on retail brand patronage patterns

In this study, we propose an alternative method for customer segmentation based on households’ retail brand portfolios. We suggest blockmodeling, a method that is rooted in social network analysis, to identify homogeneous groups of customers being characterized by similar patronage patterns. In a second step, we combine this method with psychometric analyses to examine group differences based on sociodemographic and purchasing behavior variables. To illustrate our approach, we use a sample of 500 households out of a panel data set of 36,502 German households in the fast-moving consumer goods sector. The findings of our analyses yield support for our assumption that our methodology, taking into account the relationship between households and the different retail brands they patronize, provides a broader understanding of the antecedents of households’ multiple store patronage strategies, leading eventually to a new form of customer segmentation.     

The Erosion of the German Middle Class

Since the mid-1990s, income inequality has increased more sharply in Germany than in many other European countries, as the economic basis of middle-class prosperity and security has crumbled. The new minimum wage, an increase in coverage by collective agreements, the re-regulation of atypical employment forms and the elimination of incentives to take marginal, part-time jobs are the keys to strengthening the middle-income groups in Germany.     

WHITHER PANAMA? CONSTRUCTING A CONSISTENT AND BALANCED WORLD SUT SYSTEM INCLUDING INTERNATIONAL TRADE AND TRANSPORT MARGINS

This paper extends work done within the World Input–Output Database project (WIOD), which compiled supply and use tables (SUTs) for 40 countries, covering about 85% of the world economy, by adding SUTs for the “rest of the world” (RoW), the approximately 15% of the world economy not covered by the 40 countries included in the WIOD database, ensuring a consistent and balanced world SUT system. The term “consistency” means that at the world level, all flows of goods and services balance, properly accounting for trade and transport services used in international trade (the “cif-fob difference”). This results in SUTs for the RoW which, together with bilateral trade matrices for all commodities (and together with the 40 national SUTs from the WIOD project), describe a consistent SUT system at the world level.     

Posting of workers in the single market: attempts to prevent social dumping and regime competition in the EU

The so‐called ‘Posting of Workers Directive’ was an integral part of the European Commission (EC) Action programme linked to the Community Charter of Fundamental Rights of Workers and was meant to establish a legal frame for labour conditions of workers posted for a temporary period to another Member State. Its content is about equal treatment, a guarantee of minimum protection, fair competition and respect for the regulatory frame in the host country. In the cases included in this article, increased divergence can be observed with respect to the role of the state versus the social partners with regards to regulation and control. The over‐riding challenge nowadays is to develop effective mechanisms of enforcement compatible with the constraints of European Union principles and regulations. In the EC documents, any reference to the Community Charter of Basic Rights of Workers has disappeared and the weight of power has shifted in favour of the free market hardliners, who seem to regard the Directive as an oddity in breach with the logic of the four freedoms.
