Fundamentals or trends? A long-term perspective on house prices

Using a long-term time series covering 350 years of house prices along the Herengracht in Amsterdam, we examine whether a fundamental factor or a trend explains house prices and whether their explanatory power is time varying. We find that agents in the housing market switch in their formation of expectations about future changes in house prices between fundamental and momentum strategies. Specifically, we show that agents base their expectations more on fundamentals during economic slowdowns and more on recent trends or momentum during economic booms.     

Handling Missing Data by Re-approaching Non-respondents

When handling missing data, a researcher should be aware of the mechanism underlying the missingness. In the presence of non-randomly missing data, a model of the missing data mechanism should be included in the analyses to prevent the analyses based on the data from becoming biased. Modeling the missing data mechanism, however, is a difficult task. One way in which knowledge about the missing data mechanism may be obtained is by collecting additional data from non-respondents. In this paper the method of re-approaching respondents who did not answer all questions of a questionnaire is described. New answers were obtained from a sample of these non-respondents and the reason(s) for skipping questions was (were) probed for. The additional data resulted in a larger sample and was used to investigate the differences between respondents and non-respondents, whereas probing for the causes of missingness resulted in more knowledge about the nature of the missing data patterns.     

Economische Groei en Spaargedrag

The impact of a differential saving function on distributive shares and rate of profit during the process of steady-state growth is presented by means of Pasinetti theorems. Some attention is also paid to the differences between post-Keynesian, neo-Keynesian and neo-classical models of economic growth.     

Continental Factors in International Real Estate Returns

This paper examines the extent to which real estate returns are driven by continental factors. This subject is relevant for determining the country allocation of international real estate portfolios. If returns are driven by a continental factor, investors should look for diversification opportunities outside their own continent. This paper finds strong continental factors in North America and especially in the United States. For the Asia–Pacific region, real estate returns are not driven by a continental factor. The results suggest that, for European, North American and Asia—Pacific real estate portfolio managers, the Asia—Pacific region provides attractive international diversification opportunities.     

Operations Research in passenger railway transportation

In this paper we give an overview of state-of-the-art Operations Research models and techniques used in passenger railway transportation. For each planning phase (strategic, tactical and operational), we describe the planning problems arising there and discuss some models and algorithms to solve them. We do not only consider classical, well-known topics such as timetabling, rolling stock scheduling and crew scheduling, but we also discuss some recently developed topics such as shunting and reliability of timetables.
Finally, we focus on several practical aspects for each of these problems at the largest Dutch railway operator, NS Reizigers.     

Strategic capacity investment under uncertainty

This article considers investment decisions within an uncertain dynamic and duopolistic framework. Each investment decision involves to determine the timing and the capacity level. The simultaneous analysis of timing and capacity decisions extends work on entry deterrence/accommodation to consider a timing/delay element. We find that, when applying an entry deterrence policy, the first investor, or incumbent, overinvests in capacity for two reasons. First, it delays the investment of the second investor, or entrant. Second, the entrant will invest in less capacity. We also find that greater uncertainty makes entry deterrence more likely.     

Both Sides of the Coin: Motives for Corruption Among Public Officials and Business Employees

The aim of this study is to better understand why public officials and business employees engage in corruption. Insight into individual-level explanations for corruption was obtained with the aid of a self-report survey. The results suggest that the most indicative factors of whether or not individuals are corruption-prone are as follows: the moral conviction they have to refrain from corruption; perceptions of whether their colleagues approve of and engage in corruption; and difficulties experienced in complying with the rules on corruption. This result pattern was identical for public officials and business employees alike, and as a consequence, for both sides of corrupt acts. The latter indicates that the same motives may not only underlie corruption in both private and public sectors, but also the act of corruption in its active and passive forms. The results of the current study do not provide strong support for the assumption that economic considerations—expected costs and benefits—are crucial in predicting corruption. Based on the findings that norms and the perceived opportunity to comply are dominant factors in explaining corruption, this article focuses on the practical implications for the development of anti-corruption strategies within both public and private sectors.     

Finite project life and uncertainty effects on investment

This paper revisits the important result of the real options approach to investment under uncertainty, which states that increased uncertainty raises the value of waiting and thus decelerates investment. Typically in this literature projects are assumed to be perpetual. However, in today's economy firms face a fast-changing technology environment, implying that investment projects are usually considered to have a finite life. The present paper studies investment projects with finite project life, and we find that, in contrast with the existing theory, investments may be accelerated by increased uncertainty. It is shown that this particularly happens at low levels of uncertainty and when project life is short.
