Influence of Paternal Age on the Risk of Spontaneous Abortion

The frequency of chromosomal anomalies in spermatozoa appears to increase with male age. Because these anomalies play a role in the etiology of spontaneous abortion, an influence of paternal age on risk of spontaneous abortion is plausible but not established. The aim was to characterize this influence in a prospective study among 5,121 California women, who as members of a prepaid health plan were ...

Contests for Cooperation: A New Approach in German Innovation Policy

A new approach in German innovation policy organizes contests of proposals for developing innovation networks. Based on an overview of the different programs, we investigate the advantages and problems of such an approach. We find that this type of policy may have a relatively large impact and can, therefore, be regarded as a rather efficient instrument of innovation policy. Compared to conventional ...

Explaining Income Nonresponse: A Case Study by Means of the British Household Panel Study (BHPS)

In this paper, we explore motives of respondents for the failure to reveal earnings using the British Household Panel Study (BHPS). The BHPS collects socio-economic information of private households in Great Britain. We explain the evolution of income-nonresponse in the BHPS and demonstrate the importance of a ...

Modeling the Impacts of International Climate Change Policies in a CGE Context: The Use of the GTAP-E Model

The anticipated implications of international environmental policy strategies are critical for the success or failure of international negotiations on climate change policies.

Modeling Inflation Dynamics in Transition Economies: The Case of Ukraine

This paper explores the dynamics of inflation in Ukraine in a period of relative macroeconomic stability. The analysis of the interrelationship among inflation, money growth, wage growth, and devaluation expectations is based on impulse responses and variance decomposition of a vector autoregression model. We find that changes in devaluation expectations appear to be the most important factor driving ...

An Economic Analysis of Security Policies

This paper analyses public policy choices in the security economy from an economic perspective. It discusses the role of public goods for national and global security and identifies the importance of the first- and second-order indirect effects of insecurity on economic activity, which include the behavioural responses of agents and the government to security measures, akin to such effects in insurance ...

This paper examines the income mobility experienced by older people living in Britain and Germany during the 1990s, and identifies the influential personal attributes and ...
