Firm Size and Wages in Germany – Trends and Impacts of Mobility

The analysis of firm-size wage differentials in Germany, using data from the German Socio-Economic Panel, firstly corroborates the finding that wages rise with firm-size and shows that the rank order of mean wages between firm-size classes is stable for the period 1984–1993. Secondly, the most important novel results are as follows: (i) wage differentials between firm-size classes increased during the period investigated after controlling for individual attributes and computing with deflated values; (ii) average levels of the qualification of employees have diverged noticeably between small and large firms; (iii) movers from small to larger firms have to accept wages below the average pay of incumbents with comparable attributes in the new firms: (iv) movers to smaller firms, however, retain a portion of their higher wages in larger firms; and (v) wage differentials between smaller and larger firms decline with increasing unemployment.     

Tradable and non-tradable expenditure and aggregate demand for imports in an emerging market economy

Using an assumption of non-separability of non-tradable expenditure from imports, this paper examines the impact of the structural transformation undertaken after 2001 on imports and, in turn, the current account stance of Turkey. In this regard, an import demand function is derived under the assumption of non-separability, and is estimated using quarterly time series data from Turkey. The empirical results show that the assumption of non-separability cannot be rejected in the case of Turkey and the relative prices of non-tradable and tradable goods must be among the determinants of import demand in addition to the relative price of imports and real GDP. This result accordingly implies that recent increases in import expenditure are, to some extent, due to changes in the relative price structure in favour of non-tradable goods.

The Winner’s Curse of Human Capital

We extend a model developed by Evans and Jovanovic (1989) to explain when start-ups are credit constrained. We show that the magnitude of the credit constraint is conditioned by the relative productivity of human capital in both wage work and self-employment. The effect of predicted household income on start-up capital is used to indicate the existence of financial constraint. Empirical analysis reveals that entrepreneurs with high human capital have both greater financial wealth and greater levels of start-up capital pointing to the endogenous nature of credit constraints. High human capital relaxes financial constraints, apparently due to greater productivity of human capital in wage work than in self-employment. Those who are the least likely to be credit constrained in self-employment are those that are least likely to switch into self-employment,and vice versa.     

GDPR: A Step Towards a User-centric Internet?

While the potential empowering impact of the GDPR is huge, we argue that the ambivalent attitudes of users towards data protection, as well as the risk of differentiation of legal practice among member states, can seriously limit the real effects of the privacy reform.     

少年罪错司法防治域外借鉴研究

"有比较才有鉴别",纵观人类历史长河,放眼全球,少年罪错司法防治并非新事物。两大法系主要国家或地区都有相关详细而又完备的规定,外国有许多先进的法律制度值得我国学习和借鉴,少年罪错司法防治也不例外,当然,两大法系的少年罪错司法防治制度也有着它们各自的一些特点,我国可以在鉴别的基础上结合我国国情进行学习和吸收。     

Congestion pricing in the absence of demand functions

This paper enhances a trial-and-error implementation scheme of marginal-cost pricing on a transportation network, in the absence of explicit expression of the demand function. Link tolls and link flows are updated for the next trial with the revealed link flows for given current trial toll pattern. The method is quite simple, requiring only some function evaluations. Also, the step size is not required to be square summable, thereby leading to the improvement of the efficiency of the algorithm. The global convergence of the method is proved and some numerical results are reported to illustrate its performance.     

分税制激励与均衡效应的实证分析

科学的财政体制应该兼顾激励与公平。自1994年我国实行分税制财政体制以来，虽然财政收入增长迅速，但地区间财力差距反而拉大了。通过对分税制激励效应与均衡效应的实证分析可以看出，我国现行分税制是激励有余而均衡不足，必须对我国现行财政体制进行改革，使之兼顾激励与均衡。
