Redistribution, Fiscal Competition, and the Politics of Economic Integration

The paper examines the consequences of the economic integration of factor markets in a model with two countries that redistribute income among their residents. The social benefits in each country are financed by a source based tax on capital which is democratically chosen by its inhabitants. If either capital or labour is internationally mobile, the countries engage in fiscal competition and the partial integration of capital or labour markets is detrimental to the countries' redistributive ability. A move from partial to full integration, however, may alleviate rather than intensify fiscal competition, particularly, if the two countries face sufficiently similar economic and political conditions. In such a situation, for example, tax competition for mobile capital is softened as the labour market becomes more integrated and even vanishes if both factors are fully mobile. As a result, there is more redistribution in equilibrium and a majority of the population in each country is strictly better off.     

Systematisierung, Erklärungsbeiträge und Effekte von Innovationsbarrieren

Barriers to innovation represent a research topic which is frequently cited but seldom investigated in depth. This article contains a systematic approach to this important subject for innovation management. The authors suggest classifying barriers to innovation using four dimensions (form of appearance, level of perception, origin, and time of appearance of a barrier). Individual, organizational, and task characteristics determine the barriers to innovation. Various theoretical perspectives are considered for the purpose of identification. The effect of barriers to innovation on individuals and on the innovation itself is also discussed, and the positive as well as negative aspects of barriers to innovation are shown. This article aims to create awareness of the complexity of barriers to innovation, with a view to developing points of departure for future research in order to deepen our theoretical understanding of these barriers.     

Who is saving privately for retirement and how much? New evidence for Germany

Due to demographic change, the replacement rates of the German statutory pension scheme will decrease over the next decades. Voluntary savings for retirement will therefore increase in relevance as a method of maintaining one’s standard of living during retirement. This article examines the savings behavior for retirement on an individual level in Germany at the extensive as well as the intensive margin. First, the decision to save in general is analyzed, showing that the main determinants for saving are personal income and disposable household income. Furthermore, it is shown that migrants and individuals living in the Eastern part of Germany turn out to be less likely to have additional private savings. Second, the chosen gross saving rates are analyzed using a Tobit model, a log-normal hurdle model and a Type II Tobit model. The results suggest that the decision to save in general, as well as the saving rate, are independent of each other, leading to a loss of information if only a standard Tobit model is used. For example, higher personal income increases the probability to save for retirement, but decreases the resulting saving rate. Modeling both decisions separately thus, leads to a better understanding of the determinants of saving for old-age.     

Market Structure and the Environmental Implications of Trade Liberalization: Russia's Accession to the World Trade Organization

We investigate the environmental impacts of Russia's World Trade Organization (WTO) accession with a computable general equilibrium model incorporating imperfectly competitive firms, foreign direct investment and endogenous productivity. WTO accession increases CO₂ emissions through technique (?), composition (+) and scale (+) effects. We consider three complementary policies to limit CO₂ emissions: cap and trade, emission intensity standards and energy efficiency standards. With imperfectly competitive firms, gains from WTO accession result with any of these policies. If we assume perfectly competitive market structures, the negative environmental impacts of WTO accession are smaller and no net gains arise when environmental regulation involves energy intensity or efficiency standards.     

Market structure and competition in transition: results from a spatial analysis

The present article provides first microlevel (indirect) empirical evidence on changes in entry barriers, the determinants of firm profitability as well as the nature of competition for a transition economy. We estimate size thresholds required to support different numbers of firms for several retail and professional service industries in a large number of geographic markets in Slovakia. The 3 time periods in the analysis (1995, 2001 and 2010) characterize different stages of the transition process. Specific emphasis is given to spatial spill-over effects between local markets. Estimation results obtained from a spatial ordered probit model suggest that entry barriers have declined considerably (except for restaurants) and that the intensity of competition has increased on average. We further find that demand spill-overs and/or the effects associated with a positive correlation in unobservable explanatory variables seem to outweigh negative spill-over effects caused by competitive forces between neighbouring cities and villages. The importance of these spatial spill-over effects differs across industries.     

Hot air for sale: a quantitative assessment of Russia’s near-term climate policy options

Since January 2005 the European Union has launched an EU-internal emissions trading scheme (EU ETS) for emission-intensive installations as the central pillar to comply with the Kyoto Protocol. The EU ETS will be linked to a Kyoto emissions market where greenhouse gas emission allowances of signatory Kyoto countries can be traded. In this paper we investigate the implications of Russian market power for environmental effectiveness and regional compliance costs to the Kyoto Protocol taking into account potential linkages between the Kyoto emissions market and the EU ETS. We find that Russia may have incentives to join the EU ETS as long as the latter remains relatively separated from the Kyoto international emissions market. In this case, Russia can exert monopolistic price discrimination between two separated markets thereby maximizing revenues from hot air sales. The EU will be able to substantially reduce compliance costs if it does not restrain itself to EU-internal emission regulation schemes. However, part of the gains from extra-EU emissions trading will come at the expense of environmental effectiveness as (more) hot air will be drawn in.      

Investment and employment from large-scale photovoltaics up to 2050

Investments in renewable energy were at US$211 billion in 2010 and developing economies overtook developed ones for the first time in terms of new financial investments in renewable energy. Photovoltaics for generation of electricity from sunlight has the highest growth rate among the competing forms of renewable energy and has now begun to achieve grid parity in some regions. If these trends of investments continue, solar energy will play a major economic role. We analyze these developments and assess the ensuing amounts of investment and employment for a range of sizes of the sector of solar energy. We find that by 2050 electricity from photovoltaics could cover up to 90% of total global energy demand, with a then global capital investment in our main scenario in photovoltaic manufacturing capacity at 500 billion US$211 billion in 2010 and developing economies overtook developed ones for the first time in terms of new financial investments in renewable energy. Photovoltaics for generation of electricity from sunlight has the highest growth rate among the competing forms of renewable energy and has now begun to achieve grid parity in some regions. If these trends of investments continue, solar energy will play a major economic role. We analyze these developments and assess the ensuing amounts of investment and employment for a range of sizes of the sector of solar energy. We find that by 2050 electricity from photovoltaics could cover up to 90% of total global energy demand, with a then global capital investment in our main scenario in photovoltaic manufacturing capacity at 500 billion US₂₀₁₀ by around 2030 and 1,500 billion by 2050. Employment in photovoltaic manufacturing is predicted to rise to 6 million by 2050. Sensitivity analysis with respect to the core parameters of assumptions is supplied.     

A comment on “Egalitarianism and efficiency in repeated symmetric games” by V. Bhaskar [Games Econ. Behav. 32 (2000) 247-262]

We identify an error in Bhaskar?s (2000) Proposition 4. We provide counterexamples to this result and demonstrate that it is not correctable.     

Price convergence in the EMU? Evidence from micro data

The establishment of the European Monetary Union (EMU) was widely expected to cause price convergence among member states. In an investigation of this claim, the present study avoids problems of comparability and representativeness by using an extremely detailed and comprehensive scanner database on washing machine prices and sales volumes for 17 European countries. A hedonic regression yields country-specific time series for quality-adjusted price differentials. Statistically and economically significant deviations from the Law of One Price emerge. Log t tests firmly reject price convergence among EMU countries. Small convergence clusters can be identified but they are unrelated to EMU membership.
