Gewerkschaften auf dem Rückzug? Mythen,Fakten und Herausforderungen

A comparison across 20 advanced countries shows that trade union density has fallen in most countries over the last 50 years, with substantial differences between countries. However, unions are not about to vanish everywhere, and some prominent explanations for union decline such as globalization do not hold on closer scrutiny. Current trends that pose serious problems for union membership are demographic change, the declining employment share of the public sector, the rise in atypical employment, and the decline in average firm size. Upholding union presence at the workplace is crucial for keeping and winning members, and union recruiting should focus more on young and atypically employed workers.     

ANFA – nationale Geldschöpfung als Sprengsatz für die Währungsunion?

The so called ANFA secret protocol brought to the public’s attention the previously only little noticed opportunity for national central banks of individual Eurozone members to create money through purchases of securities at their own expense. The ANFA financial assets amount to the significant share of 51% (gross) or rather 18% (net) of the Eurosystem’s balance sheet total and 41% of its total liquidity, thereby jeopardising the principle that the communities of the emitting and the money accepting countries should be congruent, which is seen as a stability condition for currency unions. There is a danger that the money creation via ANFA acts as an explosive device for the currency union. It is therefore necessary to clearly limit the own funds portfolio in order to restore the community of money emission.     

EU Agricultural Policy Reform: Evaluating the EU’s New Methodology for Direct Payments

The Common Agricultural Policy has changed significantly over time. Major changes are now introduced every seven years, with the last fundamental change agreed upon in 2013 for the period 2014-2020. Policymakers also agreed to a mid-term review in order to evaluate the performance of numerous new regulations. The Commission has elaborated a methodology for the evaluation and has already published some documents with initial results for past periods. This article reviews whether the methodology and database used by the Commission are in line with the highest standards for policy evaluation.     

公司税收规避、税率持续性与股票收益波动率

从税率平稳性角度看,避税活动是否会增加税率波动性进而给企业带来高风险是一个值得探讨的重要问题。从动态视角研究发现,避税是一种策略性行为,低实际税率的企业相比高实际税率的企业,其税率在长时期内能够保持平稳。此外,避税活动并不一定会带来未来税率和股票收益的波动性。这说明公司通常采用持续、稳定的税收策略,不会带来公司风险的激增。进一步研究发现：节税率的波动性与公司未来股票收益波动存在着显著正相关,即当避税引起税率波动较大时,会带来公司股票收益风险的增加。     

How safe are the safe haven assets?

The aim of this paper is to examine which of the assets commonly believed to be safe havens do, in fact, protect investors during periods of severe financial instability. Using a broad dataset of 32 assets over the period of 1964–2014, we examine the relationship of these assets with the US equity market during financial crises to determine which of them are safe havens for US investors, hedges, or speculations. We find that the US Treasuries and Japanese yen are the strongest safe haven investments in months characterized by large declines in market value or excessive volatility. We also document that the recent global financial crisis had significantly negative ramifications on the safe haven properties of many of these assets. Our out-of-sample analyses show that while, in general, predictive market exposures are negatively correlated with asset returns in strong market downturns, those of even the strongest safe haven assets are often statistically insignificant.     

External finance and dividend policy: a twist by financial constraints

This study assesses distorting effect of financial constraints on the inverse relationship between internal and external finance by examining impact of an exogenous financing shock (i.e. a regulation released in China in 2008) on dividend policies in a quasi‐natural experimental setting. Our result shows that in the absence of the regulation, the inverse relationship holds. However, the relation is twisted by the 2008 regulation. Compared with unconstrained firms, financially constrained firms are more willing to pay dividends and are more restrained to reduce cash dividends after the regulation, despite the fact that their external financing capacities are further constrained.

Local influence analysis for Poisson autoregression with an application to stock transaction data

In statistical diagnostics and sensitivity analysis, the local influence method plays an important role and has certain advantages over other methods in several situations. In this paper, we use this method to study time series of count data when employing a Poisson autoregressive model. We consider case‐weights, scale, data, and additive perturbation schemes to obtain their corresponding vectors and matrices of derivatives for the measures of slope and normal curvatures. Based on the curvature diagnostics, we take a stepwise local influence approach to deal with data with possible masking effects. Finally, our established results are illustrated to be effective by analyzing a stock transactions data set.
