Occupational Careers and Longitudinal Data: Tools and Perspectives of Research

Over the last years, the start of an increasing number of longitudinal researches and the development of suitable techniques of analysis have made possible the study of an increasing number of questions about social mobility and individual careers. Yet there is not just one way to face the study of careers. For the richness of the information they contain, longitudinal data offer the possibility to carry out different types of analysis according to the different questions of research. In this article four different approaches to the study of work-life careers will be introduced. The objective is twofold. On one hand, the study intends to offer a brief introduction to the most recent and sophisticated techniques that can be used for the analysis of careers. On the other hand, the article aims to point out the theoretical contribution that each technique can give to the debate on social mobility. The main potentialities and limits of the techniques will be stressed too.The techniques introduced in this article represent a fruitful approach for the study of work-life histories and occupational careers. Nevertheless they can be used for the analysis of all kinds of social careers.     

Productivity, innovation and R&D: Micro evidence for Italy

By exploiting a rich firm level data-base, this paper presents novel empirical evidence on the effect of process and product innovations on productivity, as well as on the role played by R&D and fixed capital investment in enhancing the likelihood of introducing innovations at the firm level. Our results imply that process innovation has a large impact on productivity. Furthermore, R&D spending is strongly positively associated with the probability of introducing a new product, whereas fixed capital spending increases the likelihood of introducing a process innovation. The latter result might reflect the fact that new technologies are frequently embodied in new capital goods. However, the effect of fixed investment on the probability of introducing a process innovation is magnified by R&D spending internal to the firm. This implies that R&D can affect productivity growth by facilitating the absorption of new technologies.     

'Like building a new motorway': establishing the rules for ethical email use at a UK Higher Education Institution

Computer mediated communication, in particular email, is of particular importance in the Higher Education sector. In this paper, research at one Higher Education Institution on the ethical use of email is presented. Focus groups were used to gather data on the impact of email, on current patterns of use, and on perceptions of ethical use. Using the analogy of a new motorway, which everyone is expected to use but for which there are no established rules of behaviour or etiquette, the research demonstrates that some ethical guidelines for the acceptable use of email are necessary. It is argued that there needs to be a greater understanding of individual responsibility for computer mediated communication in the higher education sector.     

Financial consequences of mutual fund mergers

This study examines the impact of mutual fund mergers on performance and investment flows of target and acquiring funds. Results indicate some improvements in the post-merger performance for target funds shareholders. Results also confirm prior evidence of negative net asset flows in target funds in the pre-merger period as well as negative, but not significant, net asset flows in the years following the merger. However, a more detailed analysis allows us to observe that this lack of significance in the negative reaction of investors to mutual fund mergers is explained by the compensation of abnormally high inflows and outflows in the resultant funds. These substantial flows are significantly above the average in their market segment, especially regarding money flows. This finding provides evidence that investors pay attention to mutual fund mergers, especially institutional investors who are concentrated on the market possibilities resulting from these organizational processes.     

Financial System Development and Economic Growth in Transition Economies: New Empirical Evidence from the CEE and CIS Countries

We examine the role of financial development in economic growth in the former Communist countries of Central and Eastern Europe and the Commonwealth of Independent States during the first two decades since the beginning of transition. These countries, which had undeveloped financial systems under Communism, provide an interesting test of the relationship between financial development and growth. Our study is the broadest in terms of coverage and time period. We find that measures of financial market efficiency and competitiveness are more important than the size of the market in terms of promoting economic growth.     

Centralized versus decentralized decision-making in a county government setting

During the November 1988 election cycle, the residents of Mississippi's 82 counties were allowed to choose whether or not to switch to an alternative system for governing the construction and repair of county roads. Under the system then used statewide – the so-called beat system – each of a county's five elected supervisors determined spending priorities and allocated funds within the boundaries of his or her own district. Under the alternative system – the so-called unit system – such choices were to be made by the supervisors collectively and then executed by a hired professional road manager. This paper models the decision of voters to retain the beat system (38 counties) or to switch to the unit system (44 counties). Theory and evidence suggest that the choice between centralized versus decentralized governance depends on the perceived costs and benefits of the alternatives to voters and their elected representatives.

Addressing Heterogeneous Preferences Using Parametric Extended Spike Models

Some public programs simultaneously provide a mix of non-rejectable public goods and public bads. Consequently, some individuals would pay for the program, while others might instead need to becompensated. In this paper we estimate twoparametric extended spike models that accountfor positive and negative preferences as wellas indifference for the public good. Weillustrate the models using data on valuationof prescribed burning of underbrush in forests,which reduces the risk of catastrophicwildfires but also produces smoke emissions(the public bad). We compare the two empiricalapproaches to estimate willingness to pay (WTP)for the program and contrast these results withthose obtained from modeling specificationsthat only account for non-negative preferences.Substantial differences in public net benefitswere found between the most flexible parametricextended spike model and the simple spike modelwhere negative responses were coded as zero anda standard binary logit of only positivebidders. The results from the extended spikemodels demonstrated that accounting forindifference and negative values towards thepublic good resulted in substantially lowerwillingness to pay estimates.
