Estimation of a German money demand system – a long-run analysis

This study presents a multivariate analysis of the stability of long-run relationships between variables that influence the conduct and transmission process of the German monetary policy. The initial VAR comprises the variables real money M3, real GNP, the inflation rate, a long-term and a weighted short-term interest rate. A multivariate approach has been chosen, as this allows for more than one cointegration relationship and to test restrictions on the cointegration space. In contrast to most other studies on German monetary policy, three stable and economically plausible cointegration relationships are obtained simultaneously within the framework of the Johansen procedure: a money demand relationship, a long-run Fisher effect and a long-run relationship between the short- and the long-term interest rate. It is apparent that the structural break of German reunification can be modelled incorporating dummy variables in the model.

The unequal distribution of unequal pay – An empirical analysis of the gender wage gap in Switzerland

In this paper we analyze the distribution of the gender wage gap. Using microdata for Switzerland we estimate conditional wage distribution functions and find that the total wage gap and its discrimination component are not constant over the range of wages. At low wages an overproportional part of the wage gap is due to discrimination. In a further analysis of specific individuals we examine the wage gap at different quantiles and propose a new measure to assess equal earnings opportunities. These additional results reveal that it is primarily low education that causes the large discrimination component at low wages.

Minsky’s financial fragility: an empirical analysis of electricity distribution firms in Brazil (2007–2015)

This article applies Hyman P. Minsky’s insights on financial fragility to analyze the behavior of electricity distribution firms in Brazil from 2007 to 2015. More specifically, it builds an analytical framework to classify these firms into Minskyan risk categories and assess how financial fragility evolved over time, in each firm and in the sector as a whole. This work adapts Minsky’s financial fragility indicators and taxonomy to the conditions of the electricity distribution sector and applies them to regulatory accounting data for more than 60 firms. This empirical application of Minsky’s theory for analyzing firms engaged in the provision of public goods and services is a novelty. The results show an increase in the financial fragility of those firms as well as of the sector throughout the period, especially between 2008 and 2013.     

Agglomeration economies and clustering – evidence from German and European firms

This article empirically analyses the impact of agglomeration economies on the clustering of German and European firms using partial proportional-odds models. Firms are grouped according to industry and divided into departments. At the industry level, I find evidence for inter-industry economies derived from the New Economic Geography (NEG) framework for European firms in general and German knowledge-intensive firms in particular. At the department level, Marshallian Externalities such as the hiring of skilled labour and technological spillover, and therefore intra-industry economies, are empirically confirmed for European and German departments like Human Resources and R&D but rarely for others.     

ICT and global sourcing – evidence for German manufacturing and service firms

This paper analyses the relevance of information and communication technologies (ICT) for firms’ probability of global sourcing of inputs. Using firm-level data from Germany in 2009, which include mainly small and medium-sized firms, the empirical analysis differentiates between manufacturing and service firms. The results show some differences between the manufacturing and service sector. Controlling for various sources of firm heterogeneity, the global sourcing probability is increasing in the firms’ share of employees with Internet access in the manufacturing sector. E-commerce-intensive firms are more likely to source inputs from abroad but generally, this relationship between e-commerce and global sourcing is only robust in services and much stronger there than in manufacturing. In both sectors, it is strongest in industries with higher upstream industry diversity. Moreover, labour productivity is positively linked to global sourcing. The findings support arguments for the importance of the Internet for global trade.     

Can the link between functional and personal income distribution enhance the analysis of inequality?

The aim of this paper is to present a framework which links functional and personal income distribution. In the first part of the paper, Piketty’s book “Capital in the XXI Century” is briefly reviewed. Piketty’s framework is discussed arguing that it can only partially explain levels and changes within personal income distribution. Piketty links the returns from capital r to the rate of growth of national income g in a very innovative way comparing them within a macroeconomic framework. He claims that when returns on capital rise more quickly than the overall economy and taxes on capital remain low, a vicious circle of ever-growing dynastic wealth and growing concentration of wealth takes place. However, the rise in the inequality of personal income distribution cannot only be explained by the rise of capital incomes. An analysis of the generation of personal incomes, and consequently of inequality, requires a suitable framework that links incomes at the macroeconomic level (national accounts) and incomes at the level of the individual/household. It is possible to set up this framework starting from individual endowments and their link to the productive structure: that is to what can be called the “generating function of personal income.” This function transforms personal endowments into personal earnings, given the productive structure, the technologies, and the market rules that determine the functional distribution. Personal income distribution and its inequality are linked to the functional one through the shares of capital and labor owned by each individual. The framework introduced here seems to be a suitable tool to account for the fact that personal income distribution is inextricably tied up to different sources of inequality in the distribution of national income. Sources come from institutional and productive structures (matrix Y), but also from the distribution of endowments and of individual/household entitlements (matrix S). This approach, we argue, allows for the assessment and evaluation of the effects of “ambitious new policies,” aimed at reducing poverty and inequality ex-ante, as suggested by Atkinson in his last book.     

Do German renewable energy resources affect prices and mitigate market power in the French electricity market ?

Several empirical studies show that renewable energy sources such as wind and solar power, typically supplied at low marginal cost, can cause electricity market prices to fall. Recent theoretical research and simulations also highlight the link between the integration of renewable energy and market performance in an oligopolistic energy market. This article looks at these dynamics in the context of cross-border effects between two highly interconnected electricity markets, France and Germany. Using a rich panel dataset for hourly data from November 2009 to July 2015, I estimate the impact of German wind and solar power production on both prices and market power in the French wholesale market. The findings highlight the importance of coordinating energy policies via joint renewable energy support schemes among interconnected European electricity markets.     

Non-commercial goals and financial performance of state-owned enterprises – some evidence from the electricity sector in the EU countries

This study considers the financial performance of state-owned enterprises (SOEs) in relation to non-commercial goals. We focus on enterprises operating in the production of electricity sector in the EU countries and analyse their profitability conditioning on the level of electricity prices. We reveal that SOEs underperform as compared to their privately owned counterparts when they operate in those markets that have lower prices. This suggests that their profitability is likely to be substantially affected by pursuing goals other than profit-maximisation - providing crucial products and services at affordable prices - and emphasises a need to consider the non-commercial objectives of SOEs in the empirical research.     

Economic class and the distribution of income: a time-series analysis of the UK economy, 1955–2010

This paper contributes to our understanding of the determinants and dynamics of surplus-value using quarterly UK data, 1955–2010, and the Johansen (1988 Johansen, S. 1988. Statistical analysis of cointegrated vectors. Journal of Economic Dynamic and Control, 12: 231–54. [Crossref], [Web of Science ®] , [Google Scholar], 1991 Johansen, S. 1991. Estimation and hypothesis of cointegration vectors in Gaussian vector autoregressive models. Econometrica, 59: 1551–80. [Crossref], [Web of Science ®] , [Google Scholar]) cointegration and vector error correction model (VECM). A model is introduced to define this Marxian concept, before we explain distribution, paying attention to three forces that are traditionally seen as drivers of power in this struggle: (i) working class militancy; (ii) the size of the ‘reserve army’ of the unemployed; and (iii) political party. Our results demonstrate the ongoing relevance of Marxian economics in providing an alternative, robust and significant explanation of distribution in the post-war UK economy.     

Conceptual confusion – an analysis of the meaning of concepts in technological innovation systems and sociological functionalism

The purpose of this paper is to illustrate how conceptual confusion may be a significant obstacle to cross-disciplinary dialogue. We focus on the relationship between the framework of technological innovation systems (TIS) and sociological functionalism (SF). The paper argues that while there are similarities between the two schools of thought, in particular in the use of the terms ‘structure’ and ‘function’, these are more linguistic than substantive. We demonstrate this by assessing the validity of the spillover to TIS of four main points of critique raised against SF. We conclude by stating some lessons for improving cross-disciplinary communication.     

Estimating the economic costs of electricity deficit using input–output analysis: the case of Brazil

The objective of this article is to present a methodology to estimate the marginal cost of electric energy deficit in the long-term using input–output (I–O) analysis. We obtain a deficit marginal cost (DMC) curve that is not limited to a small number of levels, such as the curve used currently in Brazil, which is limited to four levels. The marginal cost of deficit is an important exogenous parameter used in the model’s chain to calculate the operation’s marginal cost and short-term market pricing. The electric energy deficit is a temporary lack of continuity in meeting demand, which is usually predictable and involves prior notice to the consumer. The cause of this deficit may be a lack of investment and/or low water inflows that impact the production of hydroelectric power plants. In this study, the marginal cost of the deficit is obtained from restrictions on the provision of electricity for productive sectors and by calculating the corresponding impact on the gross domestic product. The proposed methodology can be used with data from the I–O matrix of any country to estimate its marginal cost of electric energy deficit.     

Performance and the Barriers of China＇s Energy Efficiency

中国政府将加快发展能源产业、坚持节约能源和保护环境作为一项基本国策。随着我国经济的不断发展,能源消费总量虽然在逐年增加,但能源利用效率却在不断提高。在中央政府政策的推动下,能源强度虽然呈下降趋势,但近年来下降的速度明显趋于平缓,低于改革开放初期。在分析总结我国能源利用效率变化的趋势和特点的基础上,通过对能源强度系数进行分解,发现能源强度变化的技术效应和结构效应都有减弱的趋势,尤其是结构效应。在此基础上从经济发展和社会因素两方面,进一步探讨了阻碍我国能源利用效率进一步提升的原因。     

An Analysis of Energy and Environment Efficiency of China’s Iron and Steel Industry

Due to heavy energy consumption and low technical efficiency, China’s iron and steel industry is trapped in the dilemma “large but not strong”. This situation not only exerts enormous pressure on energy security but also on increased carbon emission and environmental pollution. The contribution of this study is to calculate the energy and environment efficiency of China’s iron and steel industry and to analyze the factors affecting this efficiency. An index of energy and environment efficiency is introduced based on Directional Slacks-based Distance Measure Model. This index is adopted to measure the energy and environment efficiency of China’s iron and steel industry using 2,382 firm observations during 2001 to 2005. In addition, Hierarchy Linear Model (HLM) is applied to analyze the factors which can influence the efficiency with both firm-level and province-level data. The conclusions are as follows: The energy and environment efficiency of China’s iron and steel industry did not have a significant change during the research period. A firm’s age, size, ownership, product category and the economy of its province have significant influence on its energy and environment efficiency.     

Regulatory ‘Balancing’ and the Efficiency of Green R&D

We identify and analyse several dynamic implications of setting environmental standards such as to balance marginal costs and benefits. The adoption of such a regulatory approach is shown to effect (i) the speed of improvement of abatement technologies; (ii) the direction (in a sense to be defined) of that improvement; (iii) its source and the distribution of the rents from it; and (iv) the rate of development of defensive (averting) technologies. Existing views are thoroughly synthesised in the context of a simple diagrammatic model, several new results are derived and at least one conventional wisdom questioned. The message of the analysis for legislators and regulators is that cost–benefit balancing should be done with care.     

Forecasts of the managed futures market – an empirical analysis

Alternative investments, including managed futures, are primarily intended for institutional investors and for very wealthy individual investors. It therefore seems logical to assume, that the increase of wealth on a global scale can be a factor impacting the value of transactions in individual segments of the alternative-investment market. The purpose of this article is to indicate the factors affecting growth of managed futures transactions. Another research goal is to answer the question: Does the increase of wealth on a global scale affect the value of the managed futures transactions? The article will also present short-term forecasts of the transactions on the managed futures market for the years 2015–2017. The forecasts which will be constructed are meant to present possible scenarios of the market’s further development. Evolution of the alternative investment segment leads to development of those categories, which fulfil the expectations of market participants and meet the requirement and expiration of the remaining investments which do not attract investors and are no longer accepted by them.     

The distribution of income in Sri Lanka in 1969–1970 and 1980–1981: A decomposition analysis

In 1977 the Sri Lankan government implemented a comprehensive policy of economic liberalization, removing many government controls on the economy and providing incentives for both foreign and domestic investment. The previous policies were often justified as necessary to maintain an equitable distribution of income. Income data from 1969–1970 and 1980–1981 surveys indicate that inequality has increased, but these data are shown to be unreliable for drawing conclusions on changes in the distribution of income. Expenditure data from the same surveys indicate that inequality has declined in the 1970's, both in the economy as a whole and within all sectors and ethnic groups.     

Interest rates,distribution and capital accumulation – A post-Kaleckian perspective on the US and Germany

We analyse the effects of interest rate variations on the rates of capacity utilisation, capital accumulation and profit in a simple post-Kaleckian distribution and growth model. This model gives rise to different potential accumulation regimes depending on the values of the parameters in the investment, saving and distribution function. Estimating these core behavioural equations for the US and Germany in the period 1960–2007, we find significant and robust effects of interest payments with the expected sign in each of the equations. Our estimation results imply, both for the US and for Germany, that the effects of changes in the real long-term rate of interest on the equilibrium rates of capacity utilisation, capital accumulation and profits, are characterised by the ‘normal regime’: rising long-term real rates of interest cause falling rates of capacity utilisation, capital accumulation and profits, as well as redistribution at the expense of labour income and hence an increasing profit share in both countries.     

The forward pricing function of industrial metal futures – evidence from cointegration and smooth transition regression analysis

The prices of internationally traded metals have experienced wild swings and increased volatility in recent years. The relationship between spot and futures prices is an important topic in this context, as the current period’s price of a futures contract should be an unbiased estimator of next period’s spot price under the joint assumption of risk neutrality and rationality. Taking as a basis data from the Dow Jones UBS Commodity Index, which uses metals traded on the London Metal Exchange and US exchanges, this study adopts nonlinear smooth transition models to analyze whether the forward spread is a leading indicator of future spot price movements. Our findings suggest that such a price discovery function can in most cases only be identified in periods of low volatility or small previous spreads. Moreover, the underlying dynamics are captured best by the use of a logistic transition function.     

Assessing the employment effects of the German welfare reform – an integrated CGE-microsimulation approach

The purpose of this article is to quantify the employment effects of the recent German welfare reform. The key element of this reform was to merge the coexisting transfer systems Social Assistance (SA) and Unemployment Assistance (UA) into one unified benefit (Arbeitslosengeld II – ALG II). We also consider a second reform scenario that is intended to further improve the labour supply incentives of low-skilled workers. Our methodological contribution is to use an integrated CGE-microsimulation model. In adopting such an approach, we are able to combine the advantages of microsimulation studies by accounting for the large amount of heterogeneity in terms of households’ preferences and budget constraints with the advantages of an applied general equilibrium model. The latter permits us to identify potential general equilibrium repercussions through changes in wages and unemployment. The simulations indicate that the introduction of ALG II results in a negligible increase in employment of only 45?000 individuals. In contrast, a cut in benefit levels combined with a decrease in transfer withdrawal is shown to produce somewhat larger employment effects of about 190?000 individuals.     

Karl Haushofer and geopolitics — the history of a German mythos

This essay attempts to reassess the writings of Karl Haushofer, a German professor of geopolitics during the period of the Third Reich. However, this examination is not to be another historical reflection. Instead it approaches the question what different kinds of historical reflections on Karl Haushofer as a person and his geopolitics were made in Germany and how they influenced the further geopolitical research. The different interpretations of Haushofer are examined in the form of a discourse analytic study. It shows that the different judgments concerning his work are open to diverse political interpretations.
